1-2: 💡 Verification agent🧩 Analysis chain
Verify that Go 1.19 aligns with go.mod and other build configurations.
Ensure all CI/CD stages, Dockerfiles, and
go.modfiles consistently use Go 1.19 to avoid version mismatches or build failures.

Attention: Inconsistent Go Version Configurations Detected
Our verification shows that the vendored file
vendor/github.com/dgraph-io/ristretto/.go-versionspecifies Go 1.19, while the rootgo.modis using Go 1.24.0. Additionally,vendor/modules.txtincludes several explicit Go versions (1.11, 1.16, 1.17, 1.19, 1.21), which further highlights potential version mismatches.•
vendor/github.com/dgraph-io/ristretto/.go-version: Lists Go 1.19.
•go.mod: Sets the project to Go 1.24.0.
•vendor/modules.txt: Contains multiple Go version references.Please update the configuration so that all CI/CD stages, Dockerfiles, and build files consistently use the intended Go version. This may involve updating the vendored file (if it’s safe to do so) or confirming that the distinction is intentional and documented.
🧹 Nitpick comments (156)
vendor/golang.org/x/sys/unix/.gitignore (1)
1-2: Appropriate .gitignore entries for build artifacts.Adding
_obj/andunix.testis an effective way to ensure that build artifacts or temporary test outputs are not tracked by Git. For enhanced maintainability, consider adding brief inline comments to clarify why these entries are being ignored.vendor/github.com/google/uuid/CONTRIBUTING.md (2)
3-3: Nitpick: Fix grammatical number in contribution message.
The line "We definitely welcome patches and contribution to this project!" uses a singular noun "contribution" alongside "patches." Consider changing it to "contributions" for grammatical agreement.-We definitely welcome patches and contribution to this project! +We definitely welcome patches and contributions to this project!🧰 Tools
🪛 LanguageTool
[uncategorized] ~3-~3: The grammatical number of this noun doesn’t look right. Consider replacing it.
Context: ...bute We definitely welcome patches and contribution to this project! ### Tips Commits mus...(AI_EN_LECTOR_REPLACEMENT_NOUN_NUMBER)
23-24: Refactor wording for legal requirements.
The phrase "In order to protect both you and ourselves, you will need to sign the" can be simplified for clarity and brevity. Consider rephrasing it to something like "To protect both you and us, please sign the Contributor License Agreement."-In order to protect both you and ourselves, you will need to sign the -[Contributor License Agreement](https://cla.developers.google.com/clas). +To protect both you and us, please sign the [Contributor License Agreement](https://cla.developers.google.com/clas).vendor/github.com/google/uuid/node_net.go (3)
11-11: Consider thread safety for shared cache variable.The global
interfacesvariable is used as a cache but lacks mutex protection. This could lead to race conditions if multiple goroutines callgetHardwareInterfaceconcurrently.Consider adding a mutex to protect access to this shared resource:
package uuid import ( + "sync" "net" ) var interfaces []net.Interface // cached list of interfaces +var interfacesMutex sync.RWMutexAnd in the function:
func getHardwareInterface(name string) (string, []byte) { + interfacesMutex.RLock() if interfaces == nil { + interfacesMutex.RUnlock() + interfacesMutex.Lock() + // Double check in case another goroutine initialized it + if interfaces == nil { var err error interfaces, err = net.Interfaces() if err != nil { + interfacesMutex.Unlock() return "", nil } + } + interfacesMutex.Unlock() + interfacesMutex.RLock() } // Rest of function... + defer interfacesMutex.RUnlock()
19-33: Consider implementing cache refresh mechanism.The interfaces cache is populated only once and never refreshed, which could be problematic if network interfaces change during the application's lifetime.
Consider adding a way to periodically refresh the cache or providing an explicit method to invalidate it:
// getHardwareInterface returns the name and hardware address of interface name. // If name is "" then the name and hardware address of one of the system's // interfaces is returned. If no interfaces are found (name does not exist or // there are no interfaces) then "", nil is returned. // // Only addresses of at least 6 bytes are returned. func getHardwareInterface(name string) (string, []byte) { // Existing code... } +// refreshNetworkInterfaces forces a refresh of the cached network interfaces. +// This can be called when network configuration changes are detected. +func refreshNetworkInterfaces() { + interfacesMutex.Lock() + defer interfacesMutex.Unlock() + interfaces = nil +}
23-25: Consider logging or exposing the error details.The function silently discards the specific error from
net.Interfaces(), which might make debugging difficult.Consider at least logging the error or providing an option to expose it:
func getHardwareInterface(name string) (string, []byte) { if interfaces == nil { var err error interfaces, err = net.Interfaces() if err != nil { + // Optional: Add logging here + // log.Printf("Failed to get network interfaces: %v", err) return "", nil } } // Rest of function... }vendor/golang.org/x/sys/unix/dev_aix_ppc64.go (3)
13-16: Fix documentation to refer to AIX, not LinuxThe function correctly extracts the major component of a device number for AIX systems, but the documentation incorrectly refers to a "Linux device number" instead of an "AIX device number".
-// Major returns the major component of a Linux device number. +// Major returns the major component of an AIX device number.
18-21: Fix documentation and simplify implementationThe documentation incorrectly refers to a "Linux device number" instead of an "AIX device number". Also, the

23-29: Fix documentation and declare constant at package levelThe documentation incorrectly refers to a "Linux device number". Also, the
DEVNO64constant could be defined at the package level instead of within the function for better maintainability.-// Mkdev returns a Linux device number generated from the given major and minor +// Mkdev returns an AIX device number generated from the given major and minor // components. + +const DEVNO64 uint64 = 0x8000000000000000 + func Mkdev(major, minor uint32) uint64 { - var DEVNO64 uint64 - DEVNO64 = 0x8000000000000000 return ((uint64(major) << 32) | (uint64(minor) & 0x00000000FFFFFFFF) | DEVNO64) }vendor/golang.org/x/sys/unix/dev_aix_ppc.go (3)

1-1: Badge Display – Review Badge FormattingThe opening line contains multiple badge links with extensive use of exclamation marks. While this is a common and accepted practice in README files, the static analysis hints that the punctuation may be a bit excessive. Consider reviewing whether the current formatting meets your style guidelines or if a slight simplification could improve readability.

21-25: Lock order is reversed from conventional patternThe NodeInterface function locks the mutex after setting up the defer unlock, which reverses the typical pattern. While functionally correct, this can be confusing to readers.

23-27: Interface design is concise.
A boolean return fromPush([]uint64)might limit consumer error reporting or partial processing. Consider returning an error if you anticipate more complex handling in the future.vendor/github.com/dgraph-io/ristretto/z/calloc_nojemalloc.go (1)
22-26: CallocNoRef function.
Returningnilis acceptable for a no-op version. However, ensure that callers do not rely on an actual allocated slice in this path.vendor/github.com/dgraph-io/ristretto/ttl.go (1)
24-27: bucketDurationSecs usage.
Consider making this configurable if user requirements change regarding expiration granularity.vendor/github.com/google/uuid/time.go (1)
25-31: Ensure concurrent UUID generation needs are met.Using a single global
timeMulock may limit concurrency when numerous UUIDs need to be generated simultaneously. If high-throughput parallel UUID generation is required, consider using a more scalable mechanism (e.g., sharding locks or eliminating shared mutable state).vendor/github.com/google/uuid/null.go (1)
89-98: Potential support for 'null' text.Currently, text "null" or empty is parsed by
ParseByteswhich may return an error. If you want to treat "null" literally in text encoding (matching JSON's approach), consider a direct check for"null"before parsing.vendor/golang.org/x/sys/unix/cap_freebsd.go (2)
55-88: Consider factoring out shared logic with CapRightsClear.
CapRightsSetdoes a thorough job validating version, size, and bit index, but this logic parallels much of what appears inCapRightsClear. Creating a shared helper could reduce duplication and maintenance overhead.
90-123: Repeated validation code in CapRightsClear.
As withCapRightsSet, you might refactor repeated checks (version check, index calculation, etc.) into a small helper function, ensuring consistent validation across both methods.vendor/github.com/dgraph-io/ristretto/sketch.go (3)
38-41: Consider documenting concurrency requirements for cmSketch.Currently, the
cmSketchstruct does not appear to guard against concurrent reads/writes, which can cause data races if used from multiple goroutines simultaneously. It may help to clarify in the documentation whether the user is expected to synchronize access externally or if concurrency safety is intended in future updates.
57-60: Use cryptographic randomness if collisions are security-sensitive.Seeding with
rand.NewSource(time.Now().UnixNano())is fine for general usage, but if collisions or predictability are security concerns, consider using a more secure random source (e.g.,crypto/rand). Otherwise, please document that standard pseudo-random seeding is intended.
145-156: Potential edge cases in next2Power.If
numCountersis very large (close to max int64), shifting might risk overflow. Also, consider how negative inputs should be handled or documented. Otherwise, the bitwise approach here is efficient and standard for rounding to the next power of two.vendor/github.com/dgraph-io/ristretto/z/flags.go (4)
42-47: Clarify the behavior of default flags vs. user-specified flags.
NewSuperFlagHelpaccepts a defaults string and sets up a map. Consider documenting how flag collisions are handled (e.g., if a user sets a flag again viaFlag()). This ensures consistent usage patterns for the library’s consumers.
120-123: Return explicit error rather than calling log.Fatal in library code.The constructor logs fatal errors, which halts the application. In library code, returning errors up the call stack may offer more flexibility for clients to handle failures gracefully.
180-198: Duration parsing fallback could be more flexible.Currently, if the string contains "d", it interprets it as full days only, otherwise delegates to
time.ParseDuration. This design is fine, but might surprise users. Consider documenting or expanding the day-notation usage (e.g., "1d12h" might be useful).
283-289: Warn about potential issues with user.Current in containerized or cross-compiled environments.
user.Current()can fail in restrictive environments. If it’s a critical path, you might provide a fallback mechanism or at least document the limitation.Would you like a fallback code snippet for these scenarios?
examples/example_ping/main.go (1)
10-29: Consider adding error handling for all operations.While the code works, it would be better to check for errors after each command operation, not just during client creation.
resp := client.Fire(&wire.Command{Cmd: "PING"}) fmt.Println(resp) resp = client.Fire(&wire.Command{Cmd: "SET", Args: []string{"foo", "bar"}}) fmt.Println(resp) +if resp.Error != "" { + fmt.Printf("Error setting key: %s\n", resp.Error) +} resp = client.Fire(&wire.Command{Cmd: "GET", Args: []string{"foo"}}) fmt.Println(resp) +if resp.Error != "" { + fmt.Printf("Error getting key: %s\n", resp.Error) +} resp = client.Fire(&wire.Command{Cmd: "GET", Args: []string{"foo1"}}) fmt.Println(resp) +if resp.Error != "" { + // This is expected for non-existent keys, could handle differently + fmt.Printf("Key not found: %s\n", resp.Error) +} client.Close()vendor/github.com/google/uuid/CHANGELOG.md (1)
1-42: Clear and Detailed Changelog Documentation
The changelog is well structured and clearly documents the features and bug fixes introduced in each version (1.6.0, 1.5.0, 1.4.0, and 1.3.1).

10-15: Clear Constants Definition for Memory Limits
The constantsMaxArrayLenandMaxBufferSizeare defined using bit-shift operations, which is a concise and efficient way to represent these values.Suggestion: Consider annotating the inline comments with units (e.g., "bytes") for extra clarity on what these numbers represent.

5-7: Review Build Constraint Formatting
The build constraint is correctly specified; however, there appears to be extra whitespace betweenarmbeandmipson line 5.
Suggestion: Normalize the spacing between build tags for consistency (e.g., use a single space between each tag).vendor/golang.org/x/sys/unix/aliases.go (1)
11-16: Effective Use of Type Aliases for System Call Types
The type aliases forSignal,Errno, andSysProcAttrenhance code clarity by allowing direct usage of these types from thesyscallpackage. The build constraints and Go version tags are also appropriately specified.Suggestion: Consider adding brief inline comments explaining the rationale for these aliases, which could help future maintainers.

11-15: Markdown Heading Level Consistency
The headings for the "Install" and "Documentation" sections are marked as level 6 (######), which may trigger markdown linting warnings about heading level increments.
Suggestion: Consider using a consistent and slightly higher-level heading (e.g.,## Installand## Documentation) to improve readability and adhere to common markdown style guidelines.🧰 Tools
🪛 markdownlint-cli2 (0.17.2)
11-11: Heading levels should only increment by one level at a time
Expected: h2; Actual: h6(MD001, heading-increment)
19-19: Avoid Bare URLs in Documentation
The documentation includes a bare URL (http://pkg.go.dev/github.com/google/uuid) which might trigger static analysis warnings.
Suggestion: Replace the bare URL with a proper markdown link, for example:[GoDoc](http://pkg.go.dev/github.com/google/uuid), to improve the overall presentation.vendor/github.com/google/uuid/version6.go (1)
15-20: Minor documentation issues in commentsThere's a small grammatical issue in the function documentation. The sentence "If GetTime fails to return the current NewV6 returns Nil and an error" is a bit unclear - it seems to be missing some words.
vendor/github.com/cespare/xxhash/v2/xxhash_safe.go (1)
1-2: Consider adding modern build constraint syntax.The file only uses the legacy build tag syntax. For better compatibility with newer Go versions, consider adding the modern
//go:buildsyntax.+//go:build appengine // +build appenginevendor/github.com/dustin/go-humanize/commaf.go (2)
14-20: Consider not modifying the input parameter.The function modifies the input value with
v.Abs(v), which could lead to unexpected behavior if the caller reuses the input after calling this function.func BigCommaf(v *big.Float) string { buf := &bytes.Buffer{} + var absV big.Float if v.Sign() < 0 { buf.Write([]byte{'-'}) - v.Abs(v) + absV.Abs(v) + v = &absV } else { + absV.Set(v) + v = &absV }
30-34: Avoid adding unnecessary comma only to remove it later.The current implementation always adds a trailing comma in the loop, then truncates it afterward. This works but is slightly inefficient.
- for ; pos < len(parts[0]); pos += 3 { - buf.WriteString(parts[0][pos : pos+3]) - buf.Write(comma) - } - buf.Truncate(buf.Len() - 1) + for ; pos < len(parts[0]); pos += 3 { + buf.WriteString(parts[0][pos : pos+3]) + if pos+3 < len(parts[0]) { + buf.Write(comma) + } + }vendor/github.com/dgraph-io/ristretto/z/file_default.go (1)
27-40: Error handling is inconsistent in the final step.The function returns detailed error messages for the first three operations, but returns the raw error from Mmap without formatting it consistently with the others.
var err error m.Data, err = Mmap(m.Fd, true, maxSz) // Mmap up to max size. - return err + if err != nil { + return fmt.Errorf("while mmap file: %s, error: %v\n", m.Fd.Name(), err) + } + return nilvendor/golang.org/x/sys/unix/dev_darwin.go (1)
20-24: Add input validation to Mkdev function.The function does not validate that the major number fits within 8 bits or that the minor number fits within 24 bits, which could lead to unexpected results if invalid values are provided.
func Mkdev(major, minor uint32) uint64 { + // Ensure major fits in 8 bits and minor fits in 24 bits + major &= 0xff + minor &= 0xffffff return (uint64(major) << 24) | uint64(minor) }vendor/golang.org/x/sys/unix/fdset.go (3)
11-13: Consider adding bounds check for large file descriptorsThe implementation doesn't verify if
fd/NFDBITSis within the bounds of theBitsarray. While this likely works for typical file descriptors, extremely large values could cause an out-of-bounds panic.func (fds *FdSet) Set(fd int) { + if fd < 0 || fd/NFDBITS >= len(fds.Bits) { + return + } fds.Bits[fd/NFDBITS] |= (1 << (uintptr(fd) % NFDBITS)) }
16-18: Consider adding bounds check for large file descriptorsSimilar to the
Setmethod, theClearmethod doesn't validate if the array index is within bounds.func (fds *FdSet) Clear(fd int) { + if fd < 0 || fd/NFDBITS >= len(fds.Bits) { + return + } fds.Bits[fd/NFDBITS] &^= (1 << (uintptr(fd) % NFDBITS)) }
21-23: Consider adding bounds check for large file descriptorsThe
IsSetmethod should also include bounds checking to prevent panics with large file descriptors.func (fds *FdSet) IsSet(fd int) bool { + if fd < 0 || fd/NFDBITS >= len(fds.Bits) { + return false + } return fds.Bits[fd/NFDBITS]&(1<<(uintptr(fd)%NFDBITS)) != 0 }vendor/github.com/dustin/go-humanize/.travis.yml (1)
4-14: Consider updating Go versions in CI configurationThe Travis CI configuration tests against Go versions 1.13.x through 1.16.x, which are now quite old. Consider updating to test with more recent Go versions (e.g., 1.20+).
vendor/github.com/dgryski/go-farm/farmhashmk.go (2)
20-85: Consider adding comments to explain the algorithm stepsThe
Hash32function implementation is correct, but the complex bit manipulations, rotations, and magic constants lack explanatory comments that would make the code more maintainable.You could add comments explaining:
- The purpose of constants like
c1,c2, and0xe6546b64- The different steps of the algorithm
- The reasoning behind the specific bit manipulations and rotations
15-16: Simplify slice expression for better readabilityThe slice access pattern
s[0 : 0+4]could be simplified to the more readables[0:4].- a += binary.LittleEndian.Uint32(s[0 : 0+4]) + a += binary.LittleEndian.Uint32(s[0:4])vendor/github.com/dustin/go-humanize/ftoa.go (2)
40-43: Consider adding support for special float valuesThe current implementation uses a fixed precision of 6 decimal places which may not be suitable for very large or small numbers. It also doesn't explicitly handle special float values like NaN or Infinity.
// Ftoa converts a float to a string with no trailing zeros. func Ftoa(num float64) string { + // Handle special values like NaN and Infinity + if math.IsNaN(num) { + return "NaN" + } + if math.IsInf(num, 1) { + return "+Inf" + } + if math.IsInf(num, -1) { + return "-Inf" + } return stripTrailingZeros(strconv.FormatFloat(num, 'f', 6, 64)) }
45-49: Same special case handling needed for FtoaWithDigitsSimilar to Ftoa, this function should handle special float values like NaN and Infinity.
// FtoaWithDigits converts a float to a string but limits the resulting string // to the given number of decimal places, and no trailing zeros. func FtoaWithDigits(num float64, digits int) string { + // Handle special values like NaN and Infinity + if math.IsNaN(num) { + return "NaN" + } + if math.IsInf(num, 1) { + return "+Inf" + } + if math.IsInf(num, -1) { + return "-Inf" + } return stripTrailingZeros(stripTrailingDigits(strconv.FormatFloat(num, 'f', 6, 64), digits)) }vendor/golang.org/x/sys/unix/race.go (1)
15-31: Race detection wrappers implemented correctlyThese internal functions correctly wrap the runtime's race detection functionality for use within the unix package. Consider adding documentation comments for maintainability, even though they're not exported functions.
const raceenabled = true +// raceAcquire marks the beginning of a critical section by recording that +// the current goroutine has acquired the lock at addr. func raceAcquire(addr unsafe.Pointer) { runtime.RaceAcquire(addr) } +// raceReleaseMerge marks the end of a critical section by recording that +// the current goroutine has released the lock at addr. func raceReleaseMerge(addr unsafe.Pointer) { runtime.RaceReleaseMerge(addr) } +// raceReadRange marks a read operation on memory range [addr, addr+len). func raceReadRange(addr unsafe.Pointer, len int) { runtime.RaceReadRange(addr, len) } +// raceWriteRange marks a write operation on memory range [addr, addr+len). func raceWriteRange(addr unsafe.Pointer, len int) { runtime.RaceWriteRange(addr, len) }vendor/github.com/dustin/go-humanize/big.go (1)
21-31: Similar potential overflow issue in the unlimited order of magnitude functionThe implementation of
oomfunction is correct for calculating the order of magnitude without an upper limit. However, it has the same potential issue with the return value calculation as theoommfunction.For more precise decimal representation of large integers, consider using the
Rattype from themath/bigpackage:func oom(n, b *big.Int) (float64, int) { mag := 0 m := &big.Int{} for n.Cmp(b) >= 0 { n.DivMod(n, b, m) mag++ } - return float64(n.Int64()) + (float64(m.Int64()) / float64(b.Int64())), mag + // Create a more precise representation for the fraction part + rat := new(big.Rat).SetFrac(m, b) + f, _ := rat.Float64() + return float64(n.Int64()) + f, mag }vendor/github.com/pkg/errors/Makefile (3)
13-16: Consider updating the staticcheck installation methodThe current method of installing staticcheck is outdated. The repository has moved to a new location and the installation method has changed.
staticcheck: - $(GO) get honnef.co/go/tools/cmd/staticcheck + $(GO) install honnef.co/go/tools/cmd/staticcheck@latest staticcheck -checks all $(PKGS)You can verify this by checking the current installation method:
#!/bin/bash # Check the current recommended installation method for staticcheck curl -s https://staticcheck.io/docs/getting-started/ | grep -A 5 "Installation"
17-23: Ensure misspell configuration is appropriateThe misspell configuration is using GB locale which might not be appropriate depending on your project's audience. Consider whether US English might be more suitable.
24-27: Consider updating Go tool installation methodsThe installation methods for several Go tools (unconvert, ineffassign, unparam, errcheck) use the older
go getapproach. Modern Go projects typically usego installwith versioning.For example:
unconvert: - $(GO) get github.com/mdempsky/unconvert + $(GO) install github.com/mdempsky/unconvert@latest unconvert -v $(PKGS)Apply similar changes to other tool installations.

26-30: Check for potential overflow.
Combining major and minor by shifting major left by 8 bits might overflow ifminorcan occupy more than 8 bits. Ensure calling code uses valid ranges.Change the doc comment to clarify that
minormust fit within 8 bits for correct behavior, for example:-// Mkdev returns a FreeBSD device number generated from the given major and -// minor components. +// Mkdev returns a FreeBSD device number from the given major and minor +// components.

30-40: Reduce repeated mixing for short slices if performance is critical.
hash32Len0to4repeatedly mixes data in a small loop for slices up to 4 bytes. Although this logic is likely derived from CityHash semantics, you could inline or simplify for slices of length 1, 2, 3, or 4 to reduce overhead.
53-56: Struct naming clarity.
type uint128 structis straightforward, but consider clarifying the type name to represent that it’s a higher-level data structure (e.g.,type Uint128 struct) unless you want to keep it intentionally minimal. The all-lowercase name might be less idiomatic in Go.
60-96: Potential performance trade-offs in cityMurmur.
cityMurmurprocesses data in chunks with multiple 64-bit reads, bit rotations, and repeated mixing. While correct for a reference implementation, you may gain further speed by unrolling the loop or inlining small-slice logic. Check hardware metrics to confirm necessity.
179-183: Public function usage clarity.
Fingerprint128returns twouint64values(lo, hi), requiring callers to combine them for a full 128-bit representation. Ensure this usage is well-documented so consumers of your API handle it correctly.
185-188: Alias vs. direct call.

You might consider makingNumCounters,MaxCost, andBufferItemsconfigurable to support different environments or memory constraints. Doing so can help users fine-tune caching for large or small workloads.
80-86: Consider adding a graceful shutdown mechanism for the goroutine.
The goroutine that callsListenForMessagesmay run indefinitely. You currently rely onc.wg.Wait()inClose(), but you might also want a context-based stop signal to avoid blocking if the connection is disrupted or if the user wants early termination.
220-244:ListenForMessagespanics on watch connection errors.
A panic might bring the entire service down. If you want to keep the client robust, consider more graceful error handling (return an error to the caller, log it, or attempt reconnection).vendor/golang.org/x/sys/unix/epoll_zos.go (1)
161-203:epollwaitusage of a fixed-size slice, then appending, might cause confusion.
You start withpollfds := make([]PollFd, 4)then append to it in a loop, effectively skipping the initial pre-allocated elements. Switching tomake([]PollFd, 0, 4)can be cleaner:-func (e *epollImpl) epollwait(epfd int, events []EpollEvent, msec int) (n int, err error) { - pollfds := make([]PollFd, 4) + pollfds := make([]PollFd, 0, 4)vendor/golang.org/x/sys/unix/fstatfs_zos.go (2)
16-31: Ensure error handling consistency inFstatfsfunction.
While the core logic appears sound, consider wrapping the post-call assignment ofstat_xxfields in a separate function or block. This could make the code more maintainable and reduce risk of missing future fields if the system structure changes.
32-56: Consider refactoring the pass loop for clarity.
Using aforloop with an index from 0 to 4 is clear, but employing a switch plus multiplebreakstatements might obscure the intent. A refactored approach (e.g., slice of function references) can reduce branching and repetition.-func Fstatfs(fd int, stat *Statfs_t) (err error) { ... - for passn := 0; passn < 5; passn++ { - switch passn { - case 0: - err = tryGetmntent64(stat) - break - case 1: - err = tryGetmntent128(stat) - break - ... - } - if err == nil || (err != nil && err != ERANGE) { - break - } - } +func Fstatfs(fd int, stat *Statfs_t) error { + ... + attempts := []func(*Statfs_t) error{ + tryGetmntent64, + tryGetmntent128, + tryGetmntent256, + tryGetmntent512, + tryGetmntent1024, + } + for _, attempt := range attempts { + err = attempt(stat) + if err == nil || (err != ERANGE && err != nil) { + break + } + } ... }vendor/golang.org/x/sys/unix/syscall_aix_ppc.go (1)
39-53: Consider unified error handling for file status calls.
All wrappers (Fstat,Fstatat,Lstat,Stat) directly call their respective syscalls with minimal error handling. If multiple error transformations or special cases arise in AIX environments, a shared function could unify handling.vendor/golang.org/x/sys/unix/ioctl_unsigned.go (2)
49-58: Guard against potential integer overflow inIoctlGetInt.
If the ioctl returns large numbers, storing them in a Gointmight truncate on some platforms. Confirm that all known request codes remain within the permissible range ofint.Do you want me to generate a check for unexpected large return values?
60-70: Consider inlining specialized request codes forIoctlGetWinsizeandIoctlGetTermios.
Similar to the TODO inIoctlSetWinsizeandIoctlSetTermios, if these are known to only handle certain request codes (e.g.,TIOCGWINSZ), referencing them directly can reduce confusion and potential misuse.vendor/github.com/google/uuid/hash.go (1)
28-43: Consider validating the hash length before copying.While most hashing algorithms used here (e.g., MD5, SHA1) naturally produce at least 16 bytes, the function documentation states that the hash “should be at least 16 bytes in length” but doesn't enforce it. If a non-standard or insufficient hash were mistakenly used, copying fewer bytes could lead to incorrect UUID values.
vendor/golang.org/x/sys/unix/ioctl_zos.go (2)
27-31: Window size configuration via ioctl is fine.Hardcoding
TIOCSWINSZforreqcould simplify usage in the future once any backward-compatibility concerns are resolved.
65-72: Terminal attributes retrieval logic looks good.The check for
TCGETSis correctly enforced before callingTcgetattr. Optionally, consider usingruntime.KeepAlive(&value)for consistency, though typically reading from the kernel is completed once the syscall returns.vendor/github.com/pkg/errors/errors.go (1)
181-197: Additional context with stack trace wrapping.Wrapping an error with both a new message and stack trace is helpful. However, consider if a typical usage might overlap with the Go 1.13+
%wapproach infmt.Errorf.vendor/github.com/dgraph-io/ristretto/z/bbloom.go (1)
101-108: Note about element count trackingThe
ElemNumfield is incremented for each bit set in theAddmethod rather than once per hash added. This could lead to overcounting if this field is used to track the number of unique elements added to the Bloom filter.Consider incrementing
ElemNumonly once per hash addition:func (bl *Bloom) Add(hash uint64) { h := hash >> bl.shift l := hash << bl.shift >> bl.shift for i := uint64(0); i < bl.setLocs; i++ { bl.Set((h + i*l) & bl.size) - bl.ElemNum++ } + bl.ElemNum++ }vendor/github.com/dgraph-io/ristretto/z/z.go (1)
33-57: Consider returning errors instead of panickingThe
KeyToHashfunction panics for unsupported key types. While this may be a deliberate design choice, consider returning error values instead to allow callers to handle type errors gracefully in production environments.-func KeyToHash(key interface{}) (uint64, uint64) { +func KeyToHash(key interface{}) (uint64, uint64, error) { if key == nil { - return 0, 0 + return 0, 0, nil } switch k := key.(type) { case uint64: - return k, 0 + return k, 0, nil case string: - return MemHashString(k), xxhash.Sum64String(k) + return MemHashString(k), xxhash.Sum64String(k), nil // ... other cases ... default: - panic("Key type not supported") + return 0, 0, fmt.Errorf("key type %T not supported", key) } }vendor/github.com/dgraph-io/ristretto/z/btree.go (3)
259-261: Access restriction on invalid keys.
Panicking whenkis0ormath.MaxUint64ensures reserved key space, but it forces the entire application to crash on misuse. Consider returning an error for these edge cases instead of panicking.
263-278: Potential root node expansion edge case.
Whenroot.isFull()triggers a split, the code reuses node references. Frequent root splits in rapid succession might lead to repeated buffer growth. Consider caching or reusing buffer segments to reduce allocations.
315-317: Remove or document unused code.
TheshareWithSiblingXXXfunction is commented out and marked unused. Remove it or provide usage context to avoid confusion and keep the codebase clean.vendor/golang.org/x/sys/unix/affinity_linux.go (1)
63-68: Spark warnings on out-of-bounds CPU clearing.
Wheni >= len(s), the code silently fails to clear the CPU bit. Consider logging a warning or returning an error, so that misconfigurations do not go unnoticed.vendor/github.com/pkg/errors/stack.go (2)
65-84: Consider cost of detailed stack traces in high-frequency use.
Frame.Formatprocesses function/file/line for each frame. In performance-sensitive paths or tight loops, repeated calls toruntime.FuncForPCcan be expensive. Consider caching or deferring the resolution if profiling indicates high overhead.
108-116: Refrain from printing partial stack traces by default.
Using+vcan generate extensive multi-line output. If too verbose, consider a short summary or a configurable detail level—particularly important if logs might become noisy in production.vendor/golang.org/x/sys/unix/sockcmsg_unix.go (1)
38-53: Suggest testing for partial/truncated message scenarios.
While this parsing logic is correct and idiomatic, it would be beneficial to add unit tests that verify behavior when the byte slice is truncated or partially contains control message data. This helps ensure graceful error handling and prevents any unsafe corner cases.vendor/github.com/dgraph-io/ristretto/z/file.go (2)
36-36: Minor naming note.
The global variableNewFileis used as a sentinel error rather than a function. Consider renaming it (e.g.,ErrNewFile) for clarity, to better match Go error variable naming conventions.
166-184: Good cleanup sequence on Delete.
Unmapping before truncation and file removal helps avoid stray references to stale memory. This function is consistent with well-managed file resources, though be mindful of concurrency if multiple goroutines interact with the file concurrently.vendor/github.com/dgraph-io/ristretto/z/histogram.go (2)
37-46: Consider validating input for Fibonacci generation.
Currently, the function only assertsnum > 4. If a smaller number is passed, the function panics. You might consider returning an error or handling it gracefully to maintain production-grade reliability.
169-192: Enforce validity ofpinPercentile.
Though the doc statespmust be [0.0 - 1.0], no explicit check is implemented. CallingPercentile(2.0)or a negative p might not produce meaningful results.Consider:
func (histogram *HistogramData) Percentile(p float64) float64 { + if p < 0 || p > 1 { + return 0 // or histogram.Bounds[0], or an error + } ...vendor/github.com/google/uuid/uuid.go (1)
164-172: Panic-based error handling.
MustParsepanics if parsing fails, which may or may not be desired in production code. This is commonly acceptable for initialization flows, though.vendor/github.com/dgraph-io/ristretto/z/allocator.go (2)
181-194: Check partial trim behavior.
TrimTofrees entire buffers only after crossingmax. Ifallocis huge, the leftover could be large. This is presumably intended, but confirm if partial buffer trimming was required.
224-237:AllocateAlignedzeroes memory forcibly.
This is good for safety, but can introduce overhead for large allocations. Evaluate performance trade-offs if this is called frequently.vendor/golang.org/x/sys/unix/syscall_aix.go (1)
330-333: Implement or remove the unimplementedsendfilefunction.
Currently,sendfilereturnsENOSYSand is marked with aTODO; you might consider either implementing it if the underlying AIX syscall becomes available or removing it if it is not planned for future use.Do you want me to open a tracking issue or provide a fallback approach for file transfers on AIX?
vendor/github.com/dgraph-io/ristretto/z/buffer.go (1)
58-73: Consider providing an error return instead of panicking on allocation failures.
This constructor panics ifCallocor file operations fail. Depending on usage, returning an error can be more flexible than panicking in library code.-func NewBuffer(capacity int, tag string) *Buffer { +func NewBuffer(capacity int, tag string) (*Buffer, error) { ... - panic(err) + return nil, err }vendor/github.com/dgraph-io/ristretto/policy.go (1)
134-208: Avoid potential linear scans insampledLFUunder high load.
When evicting items,fillSamplescans potentially many entries. Under high or skewed workloads, consider a more efficient data structure (e.g., random indexing or min-heap) to reduce eviction overhead and improve throughput.vendor/github.com/dgraph-io/ristretto/store.go (4)
24-30: Consider mergingstoreItemwithItem.There's a TODO comment questioning the need for a separate
storeItemstruct. If the fields align closely withItem, merging them might reduce duplicated definitions and simplify maintenance.
70-79: Parameterize the number of shards.
numShardsis currently a fixed constant (256). Making this configurable could help adapt to different workloads or hardware environments while retaining the benefits of sharding.
129-145: Remove expired items eagerly to free up memory.While returning
falsefor expired entries prevents stale reads, it leaves the items in the map untilCleanupruns. Consider removing them immediately to conserve memory and reduce potential collisions in high-churn scenarios.
229-242: Handle eviction failures gracefully.
Clearperforms eviction callbacks under a single lock and doesn't accommodate partial failures. IfonEvictencounters errors, consider adding an error-handling mechanism or partial rollback strategy.vendor/golang.org/x/sys/unix/ioctl_linux.go (1)
108-148: Ensure safe handling of dedupe range buffers.Manual construction of the buffer for
IoctlFileDedupeRangeis prone to out-of-bounds or alignment mistakes. Regularly review and test these bounds for different platforms to avoid memory corruption issues.vendor/golang.org/x/sys/unix/syscall_bsd.go (1)
599-603: Offer help with the TODO calls.There is a
TODOindicating additional calls (e.g.,Acct,Gethostuuid,Ptrace) may need wrapping. Let me know if you'd like assistance creating appropriate Go wrappers for these system calls.vendor/github.com/dgraph-io/ristretto/cache.go (3)
34-37: Consider makingsetBufSizeconfigurable.Hardcoding
setBufSize = 32 * 1024can limit flexibility under different workloads. A configurable option inConfig(or an environment variable) might better accommodate varying usage patterns and reduce the risk of either excessive memory usage or dropped sets under high contention.-var ( - // TODO: find the optimal value for this or make it configurable - setBufSize = 32 * 1024 -) +const DefaultSetBufSize = 32768 + +// In NewCache or Config, allow override via config.SetBufSize if needed. +// Example: +// if config.SetBufSize > 0 { +// setBufSize = config.SetBufSize +// }
83-140: Gracefully handle negative configuration values.Although zero values for
NumCounters,MaxCost,BufferItemsare checked, negative integers are not explicitly handled. Passing a negative value may introduce unexpected behavior or overflow in some logic.switch { case config.NumCounters <= 0: return nil, errors.New("NumCounters must be positive") case config.MaxCost <= 0: return nil, errors.New("MaxCost must be positive") case config.BufferItems <= 0: return nil, errors.New("BufferItems must be positive") ... }
429-503: MakenumToKeepconfigurable to avoid excessive memory usage.In
processItems(),numToKeepis hardcoded to100000. Large traffic or extended runtimes may cause significant memory usage instartTs. Exposing it as a configurable parameter can optimize memory usage, especially under varying traffic patterns.- numToKeep := 100000 // TODO: Make this configurable via options. + numToKeep := config.AdmissionTrackingLimit + if numToKeep <= 0 { + numToKeep = 100000 // fallback if not set + }vendor/github.com/dgraph-io/ristretto/z/simd/baseline.go (3)
10-20: Check for out-of-bounds access and clarify stepping logic.The
Naivefunction incrementsiby 2 in each iteration, but there's no boundary check before accessingxs[i]. If the slice has an odd length, this could lead to an out-of-bounds error.Additionally, the function appears to be designed for a specific data structure where elements are stored at even indices. Consider adding a comment explaining why the function steps by 2 and why the result is divided by 2.
// Search finds the key using the naive way func Naive(xs []uint64, k uint64) int16 { var i int - for i = 0; i < len(xs); i += 2 { + for i = 0; i < len(xs)-1; i += 2 { x := xs[i] if x >= k { return int16(i / 2) } } return int16(i / 2) }
92-99: Clarify the Binary search implementation.The
Binaryfunction uses a multiplication by 2 to access elements, similar to other functions in this file. This suggests a specific data structure pattern, but it's not clearly explained.Also, there's a boundary check
if i*2 >= len(keys)but its purpose isn't obvious without more context.func Binary(keys []uint64, key uint64) int16 { + // This binary search is designed for a specific data structure + // where keys are stored at even indices (0, 2, 4, etc.) return int16(sort.Search(len(keys), func(i int) bool { if i*2 >= len(keys) { return true } return keys[i*2] >= key })) }
101-130: Review unused comparison functions for consistency.The three comparison functions are marked as unused and have inconsistent behavior:
cmp2_nativechecks for equality (==)cmp4_nativechecks for greater than or equal (>=)cmp8_nativeonly compares against pk[0]If these functions are intended for future use, they should have consistent behavior and better documentation.
Consider either:
- Removing these unused functions if they're not needed
- Making their behavior consistent and adding proper documentation
- Implementing tests to verify their correctness if they will be used
//nolint:unused func cmp2_native(twos, pk [2]uint64) int16 { + // Returns the index of the first element that matches the key + // or 2 if no match is found if twos[0] == pk[0] { return 0 } if twos[1] == pk[1] { return 1 } return 2 } //nolint:unused func cmp4_native(fours, pk [4]uint64) int16 { + // Returns the index of the first element that is >= the corresponding key + // or 4 if no such element is found for i := range fours { if fours[i] >= pk[i] { return int16(i) } } return 4 } //nolint:unused func cmp8_native(a [8]uint64, pk [4]uint64) int16 { + // Returns the index of the first element that is >= pk[0] + // or 8 if no such element is found for i := range a { if a[i] >= pk[0] { return int16(i) } } return 8 }

🔇 Additional comments (414)
vendor/golang.org/x/sys/unix/constants.go (1)
1-14: LGTM: Constants for file permission checking are correctly defined.These constants (R_OK, W_OK, X_OK) are standard POSIX values used for checking file permissions via access functions. The values are correctly defined according to POSIX standards, and the file includes proper build constraints for all supported Unix-like operating systems. The inclusion of both the newer
//go:builddirective and the older+buildcomment format ensures compatibility with different Go versions.vendor/golang.org/x/sys/unix/dev_zos.go (5)
5-6: Build tags look good.The code correctly uses both the newer
//go:builddirective and the older// +buildcomment style for backward compatibility, ensuring proper compilation constraints for z/OS on s390x architecture.
8-12: Documentation is clear and helpful.The comment effectively explains the purpose of the file and correctly references the source of the implementation details (
<sys/stat.h>macros), providing valuable context for developers.
15-18: Implementation of Major function looks correct.The function correctly extracts the major component from a z/OS device number by using bit shifting (right by 16 bits) and masking operations.
20-23: Implementation of Minor function looks correct.The function correctly extracts the minor component from a z/OS device number by applying the appropriate bit mask.
25-29: Implementation of Mkdev function looks correct.The function properly combines major and minor components into a single device number using bit shifting and OR operations, providing the inverse operation to Major and Minor functions.
vendor/golang.org/x/sys/unix/asm_aix_ppc64.s (3)
1-19: Implementation follows Go assembly best practices.This assembly file properly implements system call entry points for AIX on the PPC64 architecture. The use of NOSPLIT is appropriate for system calls as it prevents stack splitting during execution, which is essential for maintaining the correct stack layout when interacting with the operating system. The file correctly delegates the actual implementation to the Go runtime package as indicated in the comments.
14-15: System call implementation matches established pattern.The
syscall6function is correctly implemented as a simple jump to the corresponding function in the runtime package. The function signature with$0-88indicates 0 bytes of local variables and 88 bytes for arguments and return values, which is consistent with a system call taking 6 parameters.
17-18: Raw system call implementation matches established pattern.The
rawSyscall6function follows the same pattern assyscall6, providing an entry point for raw system calls (those that don't retry on EINTR). This implementation is consistent with similar functions in other architecture-specific assembly files in the x/sys/unix package.vendor/golang.org/x/sys/unix/dev_aix_ppc64.go (1)
1-12: LGTM: Build constraints and package declaration look good.The build constraints correctly specify this file is only for AIX on PPC64 architecture, and the package declaration is appropriate.
vendor/golang.org/x/sys/unix/dev_aix_ppc.go (2)
1-12: LGTM: Build constraints and package declaration look good.The build constraints correctly specify this file is only for AIX on PPC architecture, and the package declaration is appropriate.
1-28: Verify the different device number formats between PPC and PPC64I notice the implementation of device number handling differs significantly between PPC and PPC64:
- PPC: Major is the high 16 bits, minor is the low 16 bits
- PPC64: Major is bits 32-61, minor is bits 0-31, with a special flag DEVNO64 (0x8000000000000000)
Please verify that these different implementations are intentional and correctly match AIX's device number format on the respective architectures.
vendor/github.com/dgryski/go-farm/VERSION (1)
1-2: Review Version File Content.
The file is meant to specify the version as2.0.1, but it appears to contain an extra line with a lone2. Please verify if the second line is intentional or if it should be removed to avoid confusion in dependency management.vendor/github.com/cespare/xxhash/v2/.travis.yml (1)
1-9: CI Configuration Looks Good.
The Travis CI configuration is well defined with the Go versions "1.x" and "master", along with two environments (one default and one with the-tags puregoflag). Confirm that both environments are required for your testing strategy.vendor/github.com/google/uuid/LICENSE (1)

The LICENSE file accurately reflects the copyright notice and redistribution conditions for this package, adhering to the original terms provided by The Go Authors.vendor/github.com/dgryski/go-farm/fp_stub.go (1)
1-10: Auto-generated fingerprint stub file verified
This auto-generated file provides the function stubs for Fingerprint64 and Fingerprint32 with proper build constraints for the amd64 architecture. As it is generated code, it should not be modified manually.vendor/github.com/pkg/errors/appveyor.yml (1)
1-32: Configuration looks goodThis AppVeyor CI configuration follows the standard patterns for Go projects, correctly setting up the environment, build, and test process.
vendor/github.com/dgryski/go-farm/fp_generic.go (1)
1-14: Implementation looks goodThe fingerprint functions are well-defined with appropriate build constraints for non-amd64 architectures. The functions provide a clean interface for generating both 32-bit and 64-bit fingerprints from byte slices.
vendor/golang.org/x/sys/unix/sockcmsg_dragonfly.go (1)
8-16: Alignment implementation is well-designedThe function correctly handles the alignment of socket control message headers, including special handling for older 64-bit DragonFly BSD systems. The bitwise calculation for alignment is efficient and follows standard practice.
vendor/github.com/dgraph-io/ristretto/z/LICENSE (1)
1-64: License file is properly documentedThe LICENSE file correctly attributes the original components (bbloom.go and rtutil.go) under MIT License with their respective copyright holders, while also specifying the Apache License 2.0 for modifications by Dgraph Labs.

vendor/github.com/cespare/xxhash/v2/xxhash_amd64.go (1)
1-13: LGTM: Properly configured hash function declarationsThe build tags are correctly configured to ensure this implementation is only used in appropriate environments. Both functions use the
//go:noescapecompiler directive which is appropriate for optimized hash functions as it prevents escape analysis overhead.vendor/github.com/dgraph-io/ristretto/CHANGELOG.md (1)
1-187: LGTM: Well-formatted changelogThe changelog follows the "Keep a Changelog" format and Semantic Versioning principles. It provides good documentation of the library's evolution with categorized changes and links to relevant PRs.

math/randusage and a reasonable line length limit of 120 characters. The selective enabling of linters provides a good balance between code quality and practicality.vendor/golang.org/x/sys/unix/dev_openbsd.go (3)
10-13: Implementation matches OpenBSD device number format.The bit manipulation for extracting the major device number correctly handles the OpenBSD device number encoding.
15-20: Correctly extracts the minor device number.The implementation properly combines bits from different positions in the device number to form the complete minor number according to OpenBSD's encoding standard.
22-29: Device number construction looks good.The
Mkdevfunction correctly assembles the device number by placing the major and minor components in their appropriate bit positions according to OpenBSD's convention.vendor/github.com/dgryski/go-farm/basics.go (4)
5-8: Well-chosen prime constants for hashing.These prime number constants are appropriately selected for hashing functions, providing good distribution properties.
10-12: Standard Murmur3 constants.These constants match the ones used in the Murmur3 hashing algorithm, which is a good choice for fast, non-cryptographic hashing.
14-22: Proper implementation of the fmix function.This mixing function follows the standard pattern for finalizing hash values in Murmur3, with appropriate bit manipulation operations to achieve good avalanche effects.
24-32: Correct implementation of the mur helper function.The function properly implements the mixing step from Murmur3, using the standard constants and bit rotation operations.

1-3: Validate build tags usage.The build tags are properly excluding App Engine, requiring gc, and skipping pure Go implementations. This seems intentional to ensure the assembly-based optimization is included only when relevant. No changes required.
57-59: Check for short slice handling.The jump to
noBlocksis guarded byCMPQ DX, $32followed byJLT noBlocks. This cleanly handles cases where the input slice is shorter than 32 bytes, preventing out-of-bounds reads in the block loop. Looks correct.
194-195: Confirm the guaranteed minimum block condition.The comment states this function is “always called with at least one block of data to process.” Please ensure all callers adhere to that contract. If there's any call site that might pass fewer than 32 bytes, it could lead to undefined behavior.
Would you like a script to search for potential caller sites that pass short slices to

NetBSD device encoding major minor💡 Result:
In NetBSD, device encoding using major and minor numbers follows the Unix tradition with specific implementation details:
Major Number Assignment
- Major numbers are statically assigned in configuration files:
- Architecture-independent devices:
/usr/src/sys/conf/majors- Architecture-specific (e.g., i386):
/usr/src/sys/arch/i386/conf/majors.i386- Example entry:
device-major skeleton char 140 skeletonassigns major 140 to a pseudo-device[1].System Representation
Devices are represented in two key contexts:
Kernel/driver level:
- Major number identifies the driver (via
cdevsw/bdevswtables)- Minor number handled internally by driver (often via
softcstruct)[1][2]Filesystem/tools:
- Mtree format:
netbsd,major,minor
Example:device=netbsd,140,0[4][7]- Tar archives: Stored in
SCHILY.devmajor/SCHILY.devminorextended attributes[8]Minor Number Usage
- Managed per driver (e.g., 0 for single-instance devices[2])
- Common approaches:
- Direct use: Single minor for simple devices
- Softc allocation: One
softcstruct per minor[1]struct rperm_softc { // Example from pseudo-device char *buf; int buf_len; } sc[2];Device Node Creation
Using
mknodwith explicit major/minor:mknod /dev/rperm c 420 0 # major=420, minor=0[2]Key implementation details:
- Major numbers ≥144 are dynamically assigned for pseudo-devices[1]
- Historical 16-bit minor limit (now extended to 32-bit via
dev_tchanges)- Maintains compatibility with POSIX device encoding standards[7][8]
This system allows precise device management while maintaining cross-tool compatibility through standardized encoding formats.

24-44: Implementation correctly provides Plan 9 placeholders returning appropriate errors.These placeholder functions for memory mapping operations on Plan 9 follow the Go pattern for unsupported OS features. All functions return
syscall.EPLAN9error as expected, which is the correct approach for this platform.Note that these unexported functions (starting with lowercase) are likely intended to be used internally by other exported functions in the package that handle cross-platform compatibility.
vendor/golang.org/x/sys/unix/dev_linux.go (2)
20-32: LGTM! Functions correctly extract Linux device number components.The implementation correctly follows the Linux device number encoding described in the comments. The bitwise operations properly extract the major and minor components according to the glibc encoding format.

36-42: Factory function is straightforward.
Initialization logic is concise and aligns with the struct’s expectations.
44-57: Push method logic is consistent.
Appending items and draining upon capacity threshold is clear. The reset pathway (make([]uint64, 0, s.capa)) is a valid way to refresh the buffer.
59-66: Struct for ring buffer is minimal and effective.
Sync pool usage is appropriate for reducing allocations.
68-82: Initialization of ringBuffer is correct.
Lossy nature of stripes insync.Pooldue to GC is acknowledged and well documented.
84-91: Push method concurrency approach.
Retrieving a stripe from the pool, pushing, then returning it ensures minimal contention. Confirm that external usage consistently pairs Get/Put calls to avoid resource leakage.vendor/github.com/dgraph-io/ristretto/z/calloc_nojemalloc.go (6)
1-7: License and build constraints.
The build tags clearly segregate jemalloc vs. non-jemalloc builds.

Documentation is sufficient to convey the intent of these no-jemalloc functions.
17-20: Calloc function.
This straightforward allocation aligns with standard Go memory usage.
28-29: Free function is no-op.
This is consistent with Go’s runtime garbage collection approach.
31-34: Leaks / StatsPrint.
Simple pass-through messaging is clear about the usage of native Go memory.
36-38: ReadMemStats is intentionally unimplemented.
No issues observed since the Go runtime handles all memory stats.vendor/golang.org/x/sys/unix/bluetooth_linux.go (3)
9-19: Bluetooth protocol constants.
Values appear to match standard Linux definitions.
21-27: HCI channel constants.
No discrepancies found with known kernel constants.

1-15: License and disclaimers.
No issues found.
17-22: Package and imports.
Usage ofsyncandtimeis typical for concurrency and scheduling.
29-37: storageBucket / cleanupBucket calculations.
Logic to offset cleanup for an additional interval ensures elements are not prematurely removed. Implementation is clear.
39-41: bucket type
A map from key → conflict is straightforward.
42-46: expirationMap struct
Use of read-write lock is appropriate for concurrent access to buckets.
48-52: newExpirationMap initialization
Instantiating the buckets map ensures subsequent methods can reliably store data.
54-74: add method
Items that don’t expire are skipped, preserving memory. Bucket creation logic is safe and concurrency is well-managed with locks.
76-97: update method
Removing the old bucket reference before inserting into the new prevents stale references. Lock usage is consistent.
99-112: del method
Skipping if the expiration is zero or if no bucket is found avoids unnecessary map operations.
114-149: cleanup method
Periodic cleanup approach is robust. Validating expiration via store ensures no premature eviction, and the onEvict callback is invoked as needed.vendor/github.com/google/uuid/time.go (3)
33-40: Validate negative or pre-epoch times.When computing
secandnsecfromt - g1582ns100, ensure that negative values oftare handled as expected.
51-67: Clock sequence incrementation logic is sound.This correctly increments the clock sequence and sets the higher variant bit if the new time is not strictly greater than
lasttime. The approach matches the recommended practice for version-based UUID generation.
110-128: Forward compatibility for Version 6 and 7.The switch statement properly accounts for multiple UUID versions, extracting the time field differently. This design ensures easier extension of future versions without breaking older logic.
vendor/github.com/google/uuid/null.go (3)
34-49: Check for consistent error handling in Scan.The logic properly sets
(nu.UUID, nu.Valid) = (Nil, false)ifvalueisnil. For non-nil values,nu.UUID.Scan(value)is delegated. Confirm that any errors fromScanare appropriately tested downstream.
60-67: Binary marshaling aligns with typical Null-value semantics.Returning an empty slice for invalid UUIDs is consistent with the
MarshalBinarycontract for null-like data. No issues spotted.
109-118: JSON handling of null UUIDs is correct.The check
bytes.Equal(data, jsonNull)ensures valid detection of null. The fallback to parsing the UUID withjson.Unmarshalfor non-null data is standard.vendor/github.com/google/uuid/dce.go (4)
23-40: Check cross-platform UID/GID usage.
NewDCESecurityand its domain-based customization are aligned with Version 2 (DCE Security). Ensureos.Getuid()andos.Getgid()usage is correct on all target platforms if compiled outside POSIX systems.
33-37: Version field setting is correct.Setting
uuid[6] = (uuid[6] & 0x0f) | 0x20properly encodes the version 2 bits in the UUID.
50-56: Group domain usage.
NewDCEGroupparallelsNewDCEPerson, substitutingos.Getgid(). The logic is straightforward and consistent.
70-80: Domain string method is comprehensive.Covers all known domain constants and provides a fallback format for unknown domains, ensuring robust string representation.
vendor/golang.org/x/sys/unix/cap_freebsd.go (5)
17-29: Constants and lookup table look consistent.
The capability version and bounds defined here appear aligned with FreeBSD’s capability approach, and thebit2idxarray seems correctly designed for bit-to-index mapping. No immediate issues from a correctness or performance standpoint.
31-53: Index and version extraction helpers are well-structured.
capidxbit(),rightToIndex(), and related version helpers cleanly encapsulate the bit manipulations, reducing the likelihood of errors. The explicit error messages (e.g., “out of range”) help with debug workflows.
125-157: Logical check for membership is correct.
CapRightsIsSetcorrectly handles partial mismatches. If any required right is absent, it returns a Boolean false immediately. This is well-structured and should behave reliably in production.
163-175: Initialization logic is clean.
CapRightsInitproperly sets up defaults before applying specified rights. No issues detected with memory usage or correctness; the appended version bits and structure layout look in line with the rest of the file.
177-196: CapRightsLimit and CapRightsGet usage is straightforward.
These routines cleanly wrap the underlying syscalls, preserving errors and providing an idiomatic Go interface. Their minimal logic appears correct and consistent with the rest of the library.vendor/github.com/dustin/go-humanize/bigbytes.go (4)
10-62: IEC and SI expansions for big.Int look correct.
The definitions ofbigIECExp,bigSIExp, and the associated big byte constants are consistent and logically grouped. This should handle large-scale conversions reliably.
64-108: Extensive suffix map is handy for parsing and canonicalization.
ThebigBytesSizeTablecovers both IEC/IEC-based suffixes and short forms. Converting suffixes to lowercase ensures uniform handling of user input. This approach looks robust.
110-146: Human-readable size formatting is straightforward.
ThehumanateBigByteshelper and public wrappers (BigBytes,BigIBytes) appear correct. The threshold-based approach for numeric formatting (e.g., using one decimal if < 10) is a nice UX detail.
148-190: Parsing byte strings is comprehensive.
ParseBigByteshandles various suffixes, optional commas, and decimal inputs. Error reporting when encountering an unknown suffix is clear. This meets typical needs for human-readable byte input.vendor/golang.org/x/sys/unix/ifreq_linux.go (4)
28-41: Interface name validation is correct.
NewIfreqenforcesIFNAMSIZ - 1, leaving room for the trailing null character. ReturningEINVALfor overly long names is aligned with typical kernel constraints.
50-88: IPv4 address getters/setters are well-defined.
The checks for the correct address family and address length help prevent invalid assignments. Clearing residual data inSetInet4Addr()viaifr.clear()is a good safety measure.
90-118: Flag and metric getters/setters are concise.
Uint16,SetUint16,Uint32, andSetUint32reliably read and write kernel-compatible numeric fields. The zeroing of union data before setting values prevents leftover bits from prior usage.
123-143: Pointer-based ifreqData approach looks appropriate.
withDataoffers a safer path for ioctls needing pointer data without mixing pointer references in the raw ifreq byte array. This maintains correct alignment and preserves type safety within the Go domain.vendor/github.com/dgraph-io/ristretto/sketch.go (2)
65-70: Increment logic appears correct.The loop and hashing operations look appropriate. Each row is incremented by XOR-ing with its seed, ensuring distribution of counters. No concerns here.
109-120:✅ Verification successful
Confirm handling of overflow wrap-around logic.
The
if v < 15check prevents overflow from saturating the 4-bit counter but never decreases it, potentially skewing usage data over time if calls toReset()are infrequent. Verify that this behavior is intended for your use case.
🏁 Script executed:
#!/bin/bash # Searching for references to increment usage to confirm the presence of frequent resets rg -A 5 'Increment'Length of output: 2957
Confirmation: The 4-bit Saturating Counter Behavior Is Intentional
The implementation in
cmRow.incrementcorrectly prevents counter wrap-around by saturating the value at 15. As observed in the LFU policy (invendor/github.com/dgraph-io/ristretto/policy.go), a reset is triggered when the increment counter reaches a threshold (p.resetAt), ensuring that usage data is periodically cleared even if some counters temporarily saturate. Please ensure that the reset frequency aligns with your workload requirements to avoid any potential skew in frequency estimates.vendor/github.com/dustin/go-humanize/humanize.go (1)
1-8: Well-documented package introductionThe package documentation clearly describes the purpose of the humanize package and gives good examples of its functionality. The formatting and structure follow Go's standard documentation practices.
vendor/github.com/pkg/errors/.travis.yml (1)

vendor/github.com/google/uuid/doc.go (1)
1-12: Clear and concise package documentationThe documentation properly explains the purpose of the uuid package, references the relevant standards (RFC 4122 and DCE 1.1), and provides key information about UUIDs. The formatting follows Go's documentation conventions.
vendor/golang.org/x/sys/unix/endian_little.go (2)
5-6: Consider updating the build tags syntaxWhile the code uses both the newer
//go:builddirective and the older// +buildstyle for compatibility, note that the older style will eventually be phased out. This is correct for now as it maintains backward compatibility with older Go versions.
8-10: Appropriate endianness constantThe constant correctly defines
isBigEndianasfalsefor little-endian architectures, which matches the file name and build constraints.vendor/golang.org/x/sys/unix/pagesize_unix.go (2)
5-6: Build constraints correctly target Unix-like systemsThe file properly uses both new and old build tag syntax for compatibility across Go versions, and correctly targets Unix-like systems where this implementation applies.
14-16: Clean wrapper implementationThe
Getpagesize()function provides a clean wrapper around the syscall implementation, maintaining API consistency within the unix package.vendor/golang.org/x/sys/unix/endian_big.go (2)
5-6: Well-defined build constraints for big-endian architecturesThe build constraints correctly identify and target big-endian architectures, ensuring the
isBigEndianconstant is only included in builds for those specific platforms.
10-10: Appropriate constant definition for endiannessThis constant properly defines the endianness for target architectures, which is essential for byte order operations in system-level programming.
vendor/github.com/dustin/go-humanize/ordinals.go (2)
5-8: Well-documented exported functionThe documentation clearly explains the function's purpose with a helpful example, following Go's best practices for public API documentation.
8-25: Comprehensive handling of ordinal suffixesThe function correctly handles all edge cases for English ordinal numbers, including the special cases for 11th, 12th, and 13th where the usual rules for numbers ending in 1, 2, and 3 don't apply.
vendor/golang.org/x/sys/unix/mmap_nomremap.go (2)
5-6: Proper OS targeting for memory mapping implementationThe build constraints correctly target Unix-like operating systems that don't support the mremap system call, ensuring platform-specific memory mapping behavior.
10-14: Correct initialization of memory mapperThe mapper variable is properly initialized with an active mapping tracker and the appropriate memory mapping functions, providing the foundation for memory-mapped operations on these platforms.
vendor/golang.org/x/sys/unix/fcntl_linux_32bit.go (2)
5-6: Precise architecture targeting for 32-bit Linux systemsThe build constraints correctly identify 32-bit Linux architectures where special handling for fcntl operations is required.
10-14: Platform-specific syscall correction for file lockingThis initialization properly sets the correct syscall (SYS_FCNTL64) for file control operations on 32-bit Linux systems, ensuring proper file locking functionality with Go's Flock_t type.
vendor/github.com/dgryski/go-farm/LICENSE (1)
1-21: License file looks good.This is a standard MIT license file for the go-farm package, properly attributing the copyright to Damian Gryski and Nicola Asuni. The MIT license is permissive and commonly used in open-source projects, allowing for both commercial and non-commercial use.
vendor/github.com/google/uuid/node_js.go (2)
5-6: Build tag syntax is correct.The build tag
+build jsensures this file is only compiled when targeting JavaScript (likely using GopherJS or WebAssembly).
9-12: Implementation provides JavaScript optimization.This implementation correctly provides a no-op version of
getHardwareInterfacefor JavaScript builds, which helps reduce the compiled JS size by removing the "net" dependency. The function signature matches what would be expected in the non-JS version, ensuring compatibility.examples/example_ping/main.go (4)
19-21: SET command implementation looks good.The code correctly fires a SET command to store "bar" under the key "foo". The response is properly printed to stdout.
22-24: GET command implementation looks good.The code correctly retrieves the previously set value for key "foo". The response is properly printed to stdout.
25-27: Testing non-existent key is good practice.Testing the GET command with a non-existent key "foo1" is a good practice to verify how the client handles keys that haven't been set.
28-28: Good resource management with client.Close().Adding the
client.Close()call ensures proper cleanup of resources when the client is no longer needed.vendor/github.com/dgryski/go-farm/.gitignore (1)
1-24: Standard Go .gitignore file.This is a standard .gitignore file for Go projects, correctly excluding common build artifacts, object files, and temporary files. Appropriately vendored as part of the dependency.
vendor/github.com/dgraph-io/ristretto/z/calloc_64bit.go (1)
1-6: Appropriate Build Constraints and File Metadata
The copyright notice and build tag comments are formatted correctly and provide the necessary build constraint details for the supported architectures.vendor/github.com/dgraph-io/ristretto/z/calloc_32bit.go (1)
9-14: Concise Constants for 32-bit Architectures
The constantsMaxArrayLenandMaxBufferSizeare clearly defined for 32-bit architectures using bit shifts, mirroring the approach in the 64-bit file.vendor/github.com/google/uuid/README.md (1)
1-10: Comprehensive README for the UUID Package
The README provides a clear overview of the package functionality and its basis on RFC 4122 and DCE 1.1 standards. The installation instructions and reference to online documentation are especially helpful.vendor/golang.org/x/sys/unix/readdirent_getdirentries.go (1)
17-19: Note the TODO item about potential optimizationThe code creates a new uint64 for the base pointer with each call, and the TODO comment suggests a potential optimization by using a single global base pointer. Since this is vendored code, you shouldn't modify it directly, but it's worth noting if this function gets called frequently in your application.
vendor/golang.org/x/sys/unix/gccgo_linux_amd64.go (1)
12-21: Implementation looks correctThis code properly interfaces with the system's gettimeofday function for Linux AMD64 when using the gccgo compiler. The error handling follows the standard pattern of converting negative return values to syscall.Errno.
vendor/golang.org/x/sys/unix/asm_solaris_amd64.s (1)
14-18: Assembly stubs look correctThese assembly stubs correctly forward system calls to the implementations in the runtime package using NOSPLIT for efficiency. This is the standard pattern for Solaris system calls on AMD64.
vendor/github.com/google/uuid/version6.go (2)
49-51: Consider verifying the behavior of setNodeInterface with empty stringThis code calls
setNodeInterface("")when nodeID is zero. Calling this function with an empty string parameter typically triggers a search across all system interfaces. Verify if this is the intended behavior for UUID generation in your application.
42-53: Overall implementation is correctThe implementation correctly constructs Version 6 UUIDs with proper time encoding, version/variant bits, and node ID. The mutex usage ensures thread safety when accessing shared state.
vendor/golang.org/x/sys/unix/readdirent_getdents.go (1)
10-13: Implementation looks good.The ReadDirent function is a clean wrapper around Getdents with proper documentation. The function signature accepts a file descriptor and buffer, returning the number of entries read and any error encountered.
vendor/github.com/google/uuid/version1.go (1)
19-44: Well-implemented UUID version 1 generator.The NewUUID function correctly implements a Version 1 UUID generator according to the specification, with:
- Proper time-based generation
- Correct version bit setting (timeHi |= 0x1000)
- Thread-safe node ID handling with mutex
- Appropriate error handling
- Efficient binary encoding
vendor/github.com/dgraph-io/ristretto/z/mremap_linux.go (1)
31-57: Appropriate implementation of Linux mremap syscall.The function correctly wraps the Linux-specific mremap system call, which allows remapping memory pages. The implementation:
- Uses the correct syscall parameters
- Properly handles error conditions
- Correctly updates the slice header to reflect the new memory mapping
Note that this code necessarily uses unsafe operations to manipulate memory directly, which is appropriate for this low-level system function but requires careful handling.
vendor/golang.org/x/sys/unix/ptrace_ios.go (1)
12-18: Appropriate stub implementation for iOS platform.These stub implementations of ptrace functions correctly return ENOTSUP, properly indicating that these operations are not supported on iOS. This is the expected pattern for maintaining API compatibility across platforms while respecting platform-specific limitations.
vendor/github.com/google/uuid/util.go (3)
11-16: Well-implemented random data generation.The
randomBitsfunction correctly usesio.ReadFullto ensure the byte slice is completely filled with random data. The panic approach is appropriate here since random generation failures typically indicate critical system-level issues that cannot be recovered from gracefully.
18-36: Efficient hex conversion lookup table.The
xvaluesarray provides an efficient O(1) lookup mechanism for converting hex characters to their byte values. The use of 255 as an invalid marker is a good choice since it's outside the valid hex value range (0-15).
38-43: Clean hex-to-byte conversion implementation.The
xtobfunction effectively combines two hex characters into a single byte using bit manipulation, while also validating both characters are valid hex digits. This is an optimal implementation for this common UUID parsing operation.vendor/golang.org/x/sys/unix/ptrace_darwin.go (2)
5-6: Properly defined build constraints.The file correctly uses both modern (
//go:build) and legacy (// +build) build constraint syntaxes for maximum compatibility across different Go versions.
12-18: Well-defined ptrace wrapper functions.Both
ptraceandptracePtrfunctions provide a clean interface to the Darwin-specific ptrace system call implementation, with appropriate parameter types for different use cases.vendor/github.com/cespare/xxhash/v2/xxhash_safe.go (1)
8-15: Safe but potentially inefficient string handling.Both functions implement safety by converting strings to byte slices, which is necessary for App Engine compatibility but introduces allocation overhead. This is an appropriate trade-off given the constraints.
vendor/github.com/dgraph-io/ristretto/z/mremap_linux_arm64.go (1)
26-52: Well-documented ARM64-specific mremap implementation.The implementation correctly handles the Linux-specific mremap system call for ARM64 architecture with proper documentation of the architectural differences. The unsafe operations are necessary and properly implemented for this low-level memory manipulation.
A couple of notes:
- The error handling is appropriate, returning the errno directly.
- The comment about ARM64's inconsistent return value is helpful documentation.
vendor/github.com/dustin/go-humanize/commaf.go (2)
1-3: Build constraint looks good.Using both modern

Consider potential overflow in order of magnitude calculation
The implementation of
oommfunction correctly calculates the order of magnitude with a maximum limit. However, there's a potential issue with the return value calculation that might lead to precision loss or incorrect results when handling very large integers.The expression
float64(n.Int64()) + (float64(m.Int64()) / float64(b.Int64()))assumes thatn,m, andbcan be represented as int64 values. For large integers outside the range of int64, this might lead to precision issues.
🏁 Script executed:
#!/bin/bash # Check if this function is used with large integers in the codebase rg -A 2 -B 2 "oomm\("Length of output: 720
Attention: Review the precision of the
oommcalculationThe current implementation converts
big.Intvalues toint64before converting them tofloat64. This approach can lead to precision loss or overflow if any ofn,m, orbcontain values outside the 64-bit integer range.
- The return expression
float64(n.Int64()) + (float64(m.Int64()) / float64(b.Int64()))
assumes that the values inn,m, andbwill fit within anint64.- Since the function is later used in
bigbytes.go, verify whether input numbers may ever exceed the safeint64range.- If there’s a possibility of larger values in your use case, consider switching to a conversion mechanism using
big.Floator applying range checks to prevent potential inaccuracies.vendor/github.com/pkg/errors/Makefile (2)

- Arguments passed in registers R4, R5, R6
- Syscall number in R2
- Return values stored in R2, R3
47-55: Correctly implemented RawSyscallNoErrorThe
RawSyscallNoErrorfunction is properly implemented without runtime notifications, which is appropriate for syscalls that don't block or when the runtime doesn't need to be notified.The register usage follows the MIPS architecture syscall convention correctly.

Confirm alignment with FreeBSD's major number encoding.
Shifting by 8 bits and masking with0xffis often correct for FreeBSD, but ensure it matches the current FreeBSD definition.Run this script to confirm that the upstream FreeBSD constants align with the chosen shift and mask:
🏁 Script executed:
#!/bin/bash # Checking relevant definitions in FreeBSD headers: fd --type f --regex 'sys/types.h$' --exec cat {} \| rg 'st_rdev'Length of output: 67
Attention: Manual Verification Required for FreeBSD Major Number Encoding
The current implementation for extracting the major number using a shift of 8 bits and masking with
0xffappears standard, but the automated script did not return the expected FreeBSD header definitions. Please manually verify the upstream FreeBSD documentation or system headers (e.g., in/usr/include/sys/types.hor/usr/include/sys/mkdev.h) to ensure this encoding fully aligns with FreeBSD’s major number definitions.

Fingerprint64andFingerprint32) optimized for the AMD64 architecture and appears to be correctly implemented.vendor/github.com/cespare/xxhash/v2/xxhash_unsafe.go (2)
28-35: Unsafe operations used for performance optimization.The implementation leverages unsafe pointer operations to avoid unnecessary string-to-byte slice copying, which is a common performance optimization for hash functions. However, this approach relies on internal string and slice representations in Go, which could potentially change in future Go versions.
For long-term maintenance, consider adding tests that would detect if the implementation breaks due to changes in Go's internal representation of strings or slices.
39-46: Similar unsafe pattern in WriteString method.This method mirrors the same unsafe approach used in Sum64String. Both implementations are common patterns for performance-critical code but should be monitored across Go version updates.

Usingint(size)in theunix.Mmapcall might introduce issues whensizeexceeds the maximum value forinton 32-bit systems. Consider ensuring thatsizewill remain within safe limits for this cast or handle it gracefully if there's a risk of overflow.Would you like a script to locate all calls where
mmapis invoked, to verify that larger file sizes aren’t passed in 32-bit environments?
36-55: Check edge cases formunmap.
The code checkslen(data) == 0 || len(data) != cap(data)and returnsunix.EINVAL. While this can prevent accidental misuse, ensure that there's no valid scenario in whichlen(data)andcap(data)might differ for a legitimate slice. Otherwise, this might lead to unintended errors for certain slices.vendor/golang.org/x/sys/unix/env_unix.go (1)
14-32: Be mindful of concurrency risks with environment variables.
Environment variables are process-wide, so multiple goroutines changing or clearing them can lead to race conditions unless carefully respected.

104-153:✅ Verification successful
Loop-based hashing for >64 bytes is well-structured but verify large inputs.
The
naHash64function processes data in 64-byte chunks, updating the internal state. The loop logic, including post-processing withhashLen16Mul(), seems correct. Consider verifying performance on very large inputs, but as vendor code, it’s consistent with farmhash references.Run the following script to confirm no known performance regressions or major differences from official farmhash implementations:

Loop-Based Hashing Implementation Looks Consistent with Official FarmHash
The implementation in
vendor/github.com/dgryski/go-farm/farmhashna.go(lines 104–153) correctly processes inputs in 64-byte chunks and updates its internal state as expected. Verification via the README confirms that this is a mechanical translation of Google's FarmHash, so the logic—including the loop and post-processing usinghashLen16Mul()—is consistent with the original reference.• The algorithm details align with the official FarmHash design.
• No discrepancies or performance regressions were apparent in the vendor-provided references.While the implementation appears correct, it is still advisable to run performance benchmarks on very large inputs to ensure parity with production benchmarks.

27-35: Ensure robust handling ofmmaperrors
This function correctly returns the error fromunix.Mmap. For better observability, consider annotating the error with context or logs if needed.
37-40:munmapusage is straightforward
Unmapping memory viaunix.Munmapis standard practice. Just ensure this function isn’t called on an already unmapped or truncated region to avoid runtime errors.
57-59:msyncimplementation looks correct
Synchronizing mapped memory viaunix.Msyncis the recommended approach.

madvisesupport on Apple Silicon
Usingsyscall.Syscallformadviseis valid on Darwin due to missing support ingolang.org/x/sys/unix. Verify it also behaves as expected on arm64.
🌐 Web query:
Is `syscall.SYS_MADVISE` fully supported on Darwin arm64 as of Go 1.20?💡 Result:
The support for
syscall.SYS_MADVISEon Darwin arm64 in Go 1.20 involves a mix of definitions and potential runtime issues, based on available documentation and historical context:
Syscall Definition:
TheSYS_MADVISEsyscall number (75) is explicitly defined for Darwin arm64 in the Go syscall package, as seen in the code from the golang-codereviews group. This confirms its inclusion in the syscall table[5][9].Implementation Challenges:
However, historical issues highlight problems withmadvise()on Darwin arm64. A 2016 bug report (issue #16850) documented crashes due tomadvise()failures during memory scavenging, returning errors in contexts where other platforms succeeded[10]. While this predates Go 1.20, it underscores platform-specific instability risks.Syscall Handling in Go:
The generated syscall code for Darwin arm64 (zsyscall_darwin_arm64.go) does not include direct wrappers formadvise, suggesting it might rely on libSystem (/usr/lib/libSystem.B.dylib) via CGO or indirect calls[3][12]. This contrasts with Linux, wheremadviseis a direct syscall[2].Runtime Behavior:
The Go runtime on Darwin uses libSystem wrappers for syscalls, as seen in the assembly code for syscall trampolines[5][12]. This implies compatibility with Darwin’s stricter syscall policies (e.g., avoiding private APIs like___getdirentries64[1]), but also potential divergence from Linux’s raw syscall behavior.Conclusion:
Whilesyscall.SYS_MADVISEis defined for Darwin arm64 in Go 1.20, its operational reliability depends on the underlying libSystem implementation and runtime integration. Developers should testmadvise-dependent code thoroughly on Apple Silicon devices, as historical edge cases (e.g., parameter validation, error handling) may persist. For memory management, prefer higher-level abstractions likesyscall.Mmapunless low-level control is necessary.Citations:

madviseBehavior on Apple SiliconThe code correctly uses
syscall.SyscallwithSYS_MADVISEon Darwin. Our recent research confirms that whileSYS_MADVISEis defined on Darwin arm64 in Go 1.20, historical issues (e.g., golang/go#16850) highlight potential runtime instability on Apple Silicon. Please ensure this functionality is thoroughly tested on arm64 devices, particularly focusing on parameter validation and error handling.

8-19: Validate slice length forh32
Since this function reads from indices [0..15], confirm the caller ensureslen(s) >= 16to avoid out-of-range panics.
21-32: Double-check negative indexing forh32Seeds
Similar toh32, this function accesses s[slen-16..slen], requiring at least 16 bytes. Verify upstream logic guarantees this size.
34-73:xohashLen33to64logic is cohesive
The multi-step hashing process appears consistent with the rest of the code. No immediate concerns.
75-84:xohashLen65to96function follows the same pattern
Usesh32for the first 64 bytes and seeds the final 32 bytes. Implementation is logically aligned with neighboring functions.
86-104: Confirm presence of helper functions inHash64
This function referenceshashLen0to16,hashLen17to32,naHash64, anduoHash64, which aren’t shown here. Ensure they exist and are tested.vendor/github.com/dustin/go-humanize/comma.go (4)
15-44:Commafunction properly handles formatting
The logic for inserting commas inint64values looks correct, including negative values and the special case formath.MinInt64.
50-77: Consider Infinity/NaN handling inCommaf
While typical floats are formatted properly, watch out for edge cases likemath.Informath.NaN, which might yield unexpected output.
79-85:CommafWithDigitsaligns well with rounding expectations
Limiting decimals by post-processing theCommafresult is concise. Implementation appears correct.
89-116:BigCommahandles large integer formatting properly
The approach for splitting giant numbers into 3-digit chunks is standard, and negative values are handled gracefully by storing and prepending the sign.vendor/golang.org/x/sys/unix/asm_linux_loong64.s (6)
1-8: Build constraints are correctly definedThe build tags specify that this file should only be compiled for Linux on Loong64 architecture using the Go compiler, which is appropriate for this architecture-specific assembly code.
16-17: Simple wrapper implementation looks goodThis is correctly implementing a jump to the syscall package's implementation of Syscall, which is a common pattern for syscall wrappers.
19-20: Syscall6 wrapper is correctly implementedSimilar to the Syscall function, this correctly jumps to the syscall package's implementation.
22-35: SyscallNoError implementation follows expected patternThe implementation correctly:
- Calls runtime.entersyscall
- Sets up registers (R4-R9) for the syscall parameters
- Performs the syscall
- Stores the result
- Calls runtime.exitsyscall before returning
This matches the pattern used for other architectures in the codebase.
37-41: RawSyscall and RawSyscall6 wrappers look goodThese are correctly implemented as jumps to the syscall package's implementations.
43-54: RawSyscallNoError implementation is correctThis implementation handles syscall parameters and results correctly for the Loong64 architecture. It properly sets up registers R4-R9, performs the syscall, and stores the result.
vendor/github.com/dgraph-io/ristretto/z/mmap_unix.go (6)
1-2: Build constraints are correctly definedThe build tags ensure this file is only compiled on Unix-like systems while excluding specific platforms (Windows, Darwin, Plan9, Linux, WASI) where different implementations might be needed.
22-26: Imports are appropriateThe file correctly imports the os package for file operations and the unix package from x/sys for the system calls needed for memory mapping.
28-36: mmap implementation is correctThe function properly:
- Sets memory protection based on the writable flag
- Uses the appropriate unix.Mmap call with the correct parameters
- Returns the byte slice and any error from the syscall
This implementation follows standard patterns for memory-mapped files on Unix systems.
38-41: munmap implementation is straightforwardThis correctly passes the byte slice to unix.Munmap for unmapping the memory.
43-52: madvise implementation handles readahead flag correctlyThe function properly:
- Sets the advice flag based on the readahead parameter
- Uses MADV_NORMAL for readahead and MADV_RANDOM for random access
- Passes the correct parameters to unix.Madvise
This is a good practice for optimizing memory access patterns.
54-56: msync implementation uses appropriate flagsThe function correctly uses the MS_SYNC flag to ensure synchronous writing of memory changes to the underlying file.
vendor/github.com/dustin/go-humanize/README.markdown (1)
1-125: Well-structured documentation with clear examplesThe README provides comprehensive documentation for the go-humanize package, including:
- Purpose and installation instructions
- Detailed sections for each feature (sizes, times, ordinals, etc.)
- Clear examples with expected outputs
- References to external resources
This will be helpful for developers using the package.
vendor/github.com/dustin/go-humanize/si.go (7)
10-32: Comprehensive SI prefix tableThe SI prefix table is complete and up-to-date, including all standard SI prefixes from quecto (10^-30) to quetta (10^30). This provides excellent coverage for a wide range of numerical values.
37-43: Efficient reverse mapping with precomputed powersThe reverse mapping function not only creates the inverse map but also precomputes the power multipliers, which is an efficient optimization for later calculations.
47-55: Clever regex construction for SI parsingThe init function dynamically builds a regex pattern using all SI prefixes from the table, which is an elegant approach that ensures the parser stays in sync with the defined prefixes.
64-85: ComputeSI function handles edge cases properlyThe function correctly:
- Handles the special case of zero
- Calculates the appropriate exponent for SI prefixes
- Handles the special case of values that are exactly 1000.0
- Preserves the sign of the input value
This ensures accurate SI prefix computation across a wide range of inputs.
117-127: ParseSI error handling is appropriateThe function properly checks for invalid input formats and returns clear errors. It also correctly handles parsing the float value and multiplying by the appropriate SI prefix magnitude.
95-108:✅ Verification successful
String formatting functions reference undefined helpers
The SI and SIWithDigits functions call
FtoaandFtoaWithDigitswhich aren't defined in this file. These are presumably defined elsewhere in the package.

Verification Complete: Helper Functions are Defined
After running the verification script, we confirmed that both
FtoaandFtoaWithDigitsare defined in the package (specifically invendor/github.com/dustin/go-humanize/ftoa.go). Therefore, the concerns about undefined helpers in theSIandSIWithDigitsfunctions are resolved.
57-64:✅ Verification successful
Missing logn function reference
The ComputeSI function uses a
lognfunction that isn't defined in this file. While it's likely defined elsewhere in the package, it would be helpful to verify this.
🏁 Script executed:
#!/bin/bash # Check if logn function is defined in the package rg -r1 "func logn" vendor/github.com/dustin/go-humanize/Length of output: 130
Logn function reference confirmed
The
lognfunction is indeed defined within the package (located invendor/github.com/dustin/go-humanize/bytes.go). The ComputeSI function correctly calls an existing utility from the package, so no code modifications are necessary. If clarity is a concern, consider enhancing the documentation by adding a comment noting the location of thelognimplementation.vendor/github.com/dgryski/go-farm/farmhashcc.go (3)
42-51: Confirm 128-to-64 downconversion approach.
hash128to64uses a Murmur-inspired approach for folding a 128-bit hash into a 64-bit result. This is consistent with known hashing practices. Confirm you’ve validated collisions and distribution with representative data for your use cases.
98-169: Ensure thorough testing across large inputs.
cityHash128WithSeedhandles rather complex logic, especially for large inputs ≥ 128 bytes. Verify boundary behaviors near 128, repeated blocks, and final tail handling. A robust test suite with random data of varying lengths is recommended.
171-177: Suitability of default seeding.
cityHash128usesk0, k1as default seeds for short slices. That’s correct per the reference. If cryptographic collision resistance is desired (often not for hash-based lookups), consider more advanced seeds or a different library. Otherwise, this is fine for typical use cases.vendor/github.com/dgryski/go-farm/farmhashuo.go (1)
15-106: Check for potential overflow in extended loops.
Hash64WithSeedsperforms repeated state updates in a loop, combining large sums and 64-bit multiples. Ensure no intermediate overflow occurs, especially if compiled for 32-bit systems. The final call touoHalso merges state. Broad test coverage across varying lengths is recommended.vendor/golang.org/x/sys/unix/asm_linux_386.s (3)
21-39: Confirm consistent runtime transitions for SyscallNoError.Lines 27–39 use
runtime·entersyscallandruntime·exitsyscall. Confirm the rest of your 386 syscalls (Syscall, Syscall6) also handle transitions similarly. This helps the Go runtime manage goroutines pre-emptively.
47-57: Alignment with typical system call patterns.
RawSyscallNoErroris consistent with typical usage ofAX,BX,CX,DX,SI,DIregisters andint 0x80. Just ensure you handle negative return values (for errors) in higher-level code if needed, as this version doesn’t handle error checking.
62-64: Centralizing syscall definitions.
rawsocketcallandseekalso simply jump to thesyscallpackage. Consolidation is clean; no changes needed. Keep them if they must be distinct for linking or runtime introspection. Otherwise, consider referencing them in doc comments for clarity.Also applies to: 65-67
main.go (6)
6-6: Imports look fine with newly introduced dependencies.
These imports (strconv, sync, ristretto, farm, structpb) seem appropriate for caching, hashing, and protobuf field handling. Ensure that yourgo.modfile pins exact versions for reproducible builds, and keep an eye on any security advisories for these libraries.Also applies to: 8-8, 11-12, 16-16
64-64: Client construction with cache reference is correct.
This line properly sets up the client with the newly created cache.
109-146: Cache usage for GET commands with subscription is promising, but watch for non-string values.
- The logic to check and store string values is correct, but verify that the server consistently returns string responses for
"GET"commands. Otherwise, type assertions might fail.- Consider how you might handle partial errors (e.g., if the server returns a different type in
resp.Value).
204-204: Properly waiting for all goroutines before closing.
Usingc.wg.Wait()ensures no goroutine is left hanging afterClose(). This is a clean approach for a graceful shutdown.
208-218: Subscription logic is straightforward but always calls "GET.WATCH".
- If you plan to support multiple subscribe commands in the future, consider a more general approach or parameterizing the subscription command.
- Also watch for error handling strategies beyond just printing an error to the console (e.g., returning or retrying).
245-251:Fingerprintusage looks correct.
Generating a uint32 fingerprint usingfarm.Fingerprint32is an efficient way to cache based on command strings. No concerns here.vendor/golang.org/x/sys/unix/dirent.go (3)
12-21:readIntfunctionality appears correct.
You correctly handle boundary checks and return(0, false)if the slice is too short. This prevents out-of-bounds errors.
23-59: Endian-specific reads are well structured.
readIntBEandreadIntLEproperly handle 1, 2, 4, and 8-byte cases, and panic on unsupported sizes. This is a clear and maintainable approach.
61-103:ParseDirentlogic is thorough.
- The loop discards invalid or empty entries and skips
"."and"..".- The boundary checks (e.g., for
reclen > len(buf)) ensure safe parsing.
If there’s a use case for including.or..entries, consider parameterizing that behavior. Otherwise, this is effectively robust.vendor/golang.org/x/sys/unix/epoll_zos.go (5)
16-22:EpollEventstruct is consistent with a Linux-like layout.
The addedPadfield aligns with the Linuxepoll_eventstruct size. If z/OS never transmits this struct to the kernel, you might removePadonce you confirm there's no need to mimic Linux alignment.
24-46: Constants mirror typical epoll flags.
Marking unsupported flags for z/OS is a good practice to avoid confusion. The documentation clarifies the difference between Linux and z/OS features.
48-121:epToPollEvtandpToEpollEvtconversions are succinct, but keep them updated.
You noted a TODO about possibly merging poll and epoll bit masks. That would simplify this mapping logic, but the current approach is still readable.
124-159:epollcreate,epollcreate1, andepollctlhandle basic epoll operations.
- Error codes like
EBADFandEEXISTare well-placed.- Consider adding a check for invalid input (e.g., negative FDs), depending on how the rest of your code uses these APIs.
205-221: High-level epoll functions are straightforward.
Your userland implementation ofEpollCreate,EpollCreate1,EpollCtl, andEpollWaitprovides a functional shim for z/OS.vendor/golang.org/x/sys/unix/asm_zos_s390x.s (1)
238-293: Verify parameter offsets in 9-argument syscall.The assembly code for
syscall_syscall9carefully writes each parameter into specific offsets like(2176+24)(R4),(2176+32)(R4), etc. If these offsets don't correctly match the expected LE structures or environmental control blocks, this could lead to corrupted parameters or undefined behavior.Please verify these offsets are correct for the z/OS s390x environment by examining the official IBM Language Environment documentation or any associated LE stack layout references.
vendor/golang.org/x/sys/unix/syscall.go (2)
37-44: Sensible string conversion check.
ByteSliceFromStringproperly checks for embedded NUL bytes and returnsEINVALif found, preventing partial truncation or corruption. This approach aligns with standard OS-level string handling.
69-85: Risk of out-of-bound reads in BytePtrToString.Although documented, there is an inherent risk of a crash if the memory pointed to by
pdoes not contain a terminating NUL. Make sure that any pointer passed in is guaranteed to be valid and NUL-terminated to avoid potential segmentation faults.Would you like a helper function or test to validate the pointer before usage?
vendor/github.com/dgraph-io/ristretto/z/rtutil.go (2)
51-54: Hash not suitable for persistence.
MemHashrelies on the runtime’s hash seed, which changes per process. This is fine for in-memory hashing but unsafe for persistent storage. Ensure that keys hashed withMemHashare never used as stable IDs across processes.
72-78: Efficient memory clearing.
MemclremploysmemclrNoHeapPointers, which is efficient for zeroing slices without pointer overhead. This approach is safe for slices known to contain no pointers. Confirm that the target slices indeed do not store pointers to avoid memory safety issues.Would you like to add a check or comment clarifying that the slice does not contain pointer fields?

61-80: Validate thatFsidconsistently matches theDevfield.
When matchingstat.Fsidtomnt_ent_buffer.filesys_info[i].Dev, ensure the platform consistently treats both as unsigned 64-bit fields. Potential type mismatches or sign extensions could lead to hard-to-detect errors.vendor/golang.org/x/sys/unix/syscall_aix_ppc.go (2)
15-21: Prevent potential overflow insetTimespecandsetTimeval.
secandnsec(orusec) can be large, and casting to 32-bit fields can lead to overflow on systems with timestamps beyond 2038. Verify if these fields must remain 32-bit for AIX PPC support.
23-37: Validate numeric boundaries on length setters.
Usinguint32orint32might risk overflow or negative values if the caller inadvertently passes in out-of-spec lengths. Confirm that upstream code restricts the lengths to valid ranges to prevent potential out-of-bounds usage.vendor/golang.org/x/sys/unix/ioctl_unsigned.go (2)
19-21: Check usage ofuintptrfor set operations.
uintptr(value)inIoctlSetIntfits many Unix ioctl definitions, but confirm the request codes never require a 64-bit pass or extended data structure.
27-30: Confirm size alignment forIoctlSetPointerInt.
int32(value)aligns to the standard Cint; still, ensure the underlying driver expects a 32-bit pointer value, not 64-bit.vendor/github.com/google/uuid/hash.go (3)
13-26: No issues found with the namespace or special UUID definitions.The well-known namespaces and special forms (
NilandMax) are introduced correctly, and the usage ofMust(Parse(...))here appears consistent with typical patterns for namespace UUIDs.
45-51: MD5-based UUID generation looks correct.No issues found. The function is a straightforward wrapper around
NewHashwith MD5.
53-59: SHA1-based UUID generation looks correct.No issues found. The function is a straightforward wrapper around
NewHashwith SHA1.vendor/golang.org/x/sys/unix/pledge_openbsd.go (4)
24-59: Well-structured implementation of the Pledge syscall.The version checks and error handling for
execpromiseson older OpenBSD releases are correct. Returning the raw error fromsyscall.Syscallis consistent with typical patterns in Go’s syscall usage.
66-91: Straightforward approach for changing only pledge promises.The function reuses the same version checks and omits
execpromises, which aligns with its documented purpose.
98-123: Straightforward approach for changing only pledge execpromises.Similar to
PledgePromises, this function adjusts onlyexecpromiseswhile leavingpromisesuntouched. The implementation is consistent with OpenBSD’s rules.
150-163: Version-based pledge availability checks are correct.No major issues identified. The conditional checks for version compatibility and
execpromisesusage align with OpenBSD’s documented pledge requirements.vendor/golang.org/x/sys/unix/ioctl_zos.go (4)
20-22: Generic integer-based ioctl usage is fine.No issues found. The function delegating to
ioctlis straightforward.
34-43: Termios set operation looks consistent.The check for valid
reqvalues and subsequent call toTcsetattris appropriate. Includingruntime.KeepAlive(value)helps ensure the pointer remains valid during the system call.
50-54: Integer retrieval from file descriptor.No issues found. This approach aligns with typical ioctl invocation patterns.
56-60: Window size retrieval approach is acceptable.No issues found. The usage of a temporary
Winsizestruct and returning it as a pointer is standard.vendor/golang.org/x/sys/unix/sockcmsg_linux.go (4)
11-22: Looks correct for credential passing.The approach of creating a buffer with
CmsgSpace(SizeofUcred), setting the levels and types, and writing theUcredis standard for sending credentials via Unix domain sockets. No immediate issues found.
24-36: Robust validation of expected socket control message level and type.Thanks for ensuring the code checks both
LevelandTypebefore decoding theUcred. This helps avoid unintended parsing of unrelated control messages.
38-58: Clean encoding of IPv4 and IPv6 packet info.Both
PktInfo4andPktInfo6correctly allocate and encode the data with properCmsgSpaceandCmsgLenusage. This matches Linux kernel expectations for IP and IPv6 control messages.
60-85: Comprehensive handling of original destination addresses.The switch on
(m.Header.Level, m.Header.Type)is crucial for supporting both IPv4 and IPv6. ReturningEINVALby default is an appropriate fallback for unknown message types.vendor/github.com/pkg/errors/errors.go (3)
95-118: Straightforward creation of new errors and formatted errors.Using
&fundamental{}to capture stack traces at creation time is a reliable approach. The logic is clear, and no obvious issues are noted.
119-143: Well-defined fundamental error structure.The code separates the message (
msg) from the stack pointer, ensuring the stack trace is captured once. This design is consistent and clear.
264-289: Thorough implementation ofCausefor retrieving root errors.The recursive approach terminates when the type no longer implements
causer. This is a proven pattern for unwrapping complex error chains.vendor/golang.org/x/sys/unix/ioctl_signed.go (7)
14-21: Safe integer setting with ioctl.Passing the integer directly as
uintptr(value)is typical. Ensure that thereqconstants used here align with the correct ioctl on AIX or Solaris systems.
23-30: Pointer-based integer ioctl usage.Using
unsafe.Pointer(&v)with a localint32ensures correct size for the data. Keep in mind potential endianness differences across platforms.
32-39: Window size manipulation.The
Winsizestructure is platform-specific, and deferring thereqparameter removal is logical for maintainability. Good job keeping the TODO visible.
41-47: Termios struct usage.Similar to the Winsize comment, parameterizing the
reqis a flexible approach, though it may be streamlined in the future.
49-58: Retrieving integer from ioctl.Appropriately returning
(value, err)ensures the integer is captured even if an error occurs. This is consistent with typical ioctl usage.
60-64: Get Winsize.Allocating a local
Winsizeand then returning a pointer is standard. No issues spotted.
66-70: Get Termios.Mirrors the Winsize logic. Looks consistent and clear.

1-211: Well-implemented Bloom filter data structureThis is a complete and efficient implementation of a Bloom filter, which is a space-efficient probabilistic data structure used to test whether an element is a member of a set. The implementation includes proper memory management, bit manipulation, and serialization/deserialization support.
153-157: Efficient bit manipulation using unsafe pointersThe bit manipulation code using unsafe pointers is an efficient approach for Bloom filters where performance is critical. This is a common pattern in high-performance Go code when direct memory access is needed.

1-237: Well-implemented xxHash algorithmThis is a thorough implementation of the 64-bit variant of xxHash (XXH64), a non-cryptographic hash function known for its high performance. The code properly implements the hash.Hash64 interface and includes optimizations.
19-31: Detailed comments explaining implementation decisionsThe extensive comments explaining the reasoning behind using both constants and variables for prime numbers demonstrate good development practices. This helps other developers understand performance tradeoffs in the code.
167-199: Proper binary marshaling implementationThe MarshalBinary and UnmarshalBinary implementations correctly handle serialization and deserialization of the hash state, including appropriate error checking and magic number validation.
vendor/github.com/dgraph-io/ristretto/z/z.go (2)
67-132: Well-designed goroutine lifecycle managementThe
Closerstruct provides a robust pattern for managing goroutine lifecycles using a combination of context and WaitGroup. The implementation includes defensive nil checks and clear documentation.
134-150: Efficient memory zeroing with fallbackThe
ZeroOutfunction properly validates indices before zeroing memory. The commented-out alternative implementation serves as a clear fallback if theMemclrfunction (which is likely more optimized) isn't available.vendor/golang.org/x/sys/unix/gccgo.go (3)
1-61: Standard syscall implementation for gccgoThis file provides appropriate syscall wrappers specific to the gccgo compiler environment. The implementation follows the standard pattern of separating regular syscalls (which use Enter/Exitsyscall) from raw syscalls.
47-60: Be cautious with Raw syscallsRaw syscalls bypass Go's scheduler since they don't call Enter/Exitsyscall. This makes them more efficient but potentially dangerous if they block, as they could prevent goroutine scheduling. Ensure these are only used when appropriate (typically for non-blocking calls).
5-6: Clear build constraintsThe build constraints are well-defined, targeting gccgo compiler but excluding aix and hurd operating systems. Both the new-style
//go:buildand legacy-style// +buildtags are included for compatibility.vendor/github.com/dgraph-io/ristretto/z/btree.go (2)
31-35: Validate pageSize alignment or negative fallback handling.
Whileos.Getpagesize()typically returns a system-aligned page size, consider safeguarding for edge cases (e.g., unusual OS returns). You might guard against unexpected values, or at least log an error ifpageSizeis zero or negative.
352-357: Careful with large-scale deletes.

The current implementation (vendor/github.com/dgraph-io/ristretto/z/simd/search.go, lines 31–50) mirrors the approach in both the baseline and assembly versions by returning an int16. However, as with the assembly code, this design assumes that the slice length (when divided by two) will never exceed 32767. Please confirm one of the following:
- The upstream or caller constraints ensure that the number of elements in xs is such that len(xs)/2 is always ≤ 32767.
- Or, consider introducing safeguards (or documenting the assumption) to prevent silent overflow if larger slices are ever passed.

Potential out-of-bounds accesses in Clever function.
The Clever function accesses elements like xs[i+2], xs[i+4], and xs[i+6] without ensuring these indices are within bounds. This could lead to panics if the slice doesn't have enough elements.
Also, the function replicates the key into a 4-element array but then performs individual comparisons, which seems unnecessary.
func Clever(xs []uint64, k uint64) int16 {
if len(xs) < 8 {
return Naive(xs, k)
}
var twos, pk [4]uint64
pk[0] = k
pk[1] = k
pk[2] = k
pk[3] = k
- for i := 0; i < len(xs); i += 8 {
+ for i := 0; i < len(xs)-7; i += 8 {
twos[0] = xs[i]
twos[1] = xs[i+2]
twos[2] = xs[i+4]
twos[3] = xs[i+6]
if twos[0] >= pk[0] {
return int16(i / 2)

Improve error handling and performance in Parallel function.
The function panics if the number of CPUs is odd, which is not a graceful error handling approach. It should adapt to any number of CPUs.
Also, the constant (1 << 15) - 1 is used as a sentinel value without explanation. Consider defining it as a named constant for better readability.
func Parallel(xs []uint64, k uint64) int16 {
cpus := runtime.NumCPU()
- if cpus%2 != 0 {
- panic(fmt.Sprintf("odd number of CPUs %v", cpus))
- }
+ // Ensure even number of CPUs for consistency
+ if cpus%2 != 0 {
+ cpus--
+ }
sz := len(xs)/cpus + 1
var wg sync.WaitGroup
retChan := make(chan int16, cpus)
for i := 0; i < len(xs); i += sz {
end := i + sz
if end >= len(xs) {
end = len(xs)
}
chunk := xs[i:end]
wg.Add(1)
go func(hd int16, xs []uint64, k uint64, wg *sync.WaitGroup, ch chan int16) {
for i := 0; i < len(xs); i += 2 {
if xs[i] >= k {
ch <- (int16(i) + hd) / 2
break
}
}
wg.Done()
}(int16(i), chunk, k, &wg, retChan)
}
wg.Wait()
close(retChan)
+ const maxInt16 = (1 << 15) - 1 // Define sentinel value as a named constant
- var min int16 = (1 << 15) - 1
+ var min int16 = maxInt16
for i := range retChan {
if i < min {
min = i
}
}
- if min == (1<<15)-1 {
