Code Review
This pull request introduces a significant new feature: data force repair for meta and tsdb data, including backup logic and detailed execution paths. While the implementation is comprehensive, a security audit identified two medium-severity issues related to how backups are handled: the default backup location in the system's temporary directory may expose sensitive data, and user-provided backup paths are not sanitized for path traversal, potentially allowing arbitrary directory creation. Furthermore, two critical race conditions related to tracking repaired vnodes in a multi-threaded context and a bug in a test helper function need to be addressed.

The global static variable tsMetaRepairDoneVnodeId is accessed and modified here without any synchronization. Since metaOpen is called in parallel for different vnodes, this will lead to a race condition when multiple threads try to update this shared string simultaneously. This can cause memory corruption or incorrect behavior.
Please protect all accesses to tsMetaRepairDoneVnodeId (in this function and in metaForceRepairMatchesVnode) with a mutex. A static TdThreadMutex would be appropriate here.

Similar to the issue in metaOpen.c, the global static variable tsTsdbRepairDoneVnodeId is modified here without thread synchronization. The tsdbDispatchForceRepair function, which calls this, is part of the parallel vnode startup process. This creates a race condition that can lead to memory corruption or incorrect repair behavior.
Please add a mutex to protect all reads and writes to tsTsdbRepairDoneVnodeId.

The variable extra_env is used within this function but is not defined as a parameter or a local variable. This will cause a NameError if the function is ever called.
Although this helper function does not seem to be used in the current test suite, this is a latent bug that should be fixed. Please add extra_env=None to the function signature.

The data repair process defaults to backing up sensitive database metadata to the system's temporary directory (/tmp) when --backup-path is not specified. On multi-user systems, /tmp is typically world-readable, which could allow unauthorized local users to access sensitive database information. It is recommended to use a more secure default location (e.g., a subdirectory within the TDengine data directory with restricted permissions) or explicitly set restrictive permissions (e.g., 0700) on the created backup directories.

The user-provided --backup-path is used to construct filesystem paths for data backups without sanitization for path traversal sequences (e.g., ..). This allows a user with the ability to run the repair command to create directories and write backup files in arbitrary locations on the filesystem. While the impact is limited by the fixed subdirectory structure appended to the path, it is best practice to sanitize the input or validate that the resolved path remains within an authorized base directory.

Pull request overview
This PR enables real execution for taosd -r --node-type vnode --file-type tsdb --mode force by dispatching repair logic inside vnode/TSDB open paths, adds backup/manifest/log handling for affected TSDB file-sets, and introduces end-to-end pytest coverage plus supporting docs/design notes. It also normalizes timezone strings (e.g., /UTC → UTC) to stabilize repair-related startup/tests.
Changes:
- Add TSDB force-repair dispatch in
tsdb open fs, including affected file-set backup (manifest + original files) and core-group drop/rebuild logic. - Add META force-repair dispatch in
metaOpen()with external backup support and CLI parameter flow accessors. - Add/extend pytest E2E coverage for repair flows and add a timezone normalization fix + unit test.

The force-repair "done" tracking uses a process-global CSV string (tsMetaRepairDoneVnodeId) that is read/modified from metaOpen(). Vnodes are opened concurrently (vmOpenVnodes launches multiple threads), so this introduces a data race and possible string corruption, leading to repeated or skipped repairs. Protect the read/check/append with a mutex (or replace the string with a thread-safe set/bitmap keyed by vgId).

The TSDB force-repair "done" tracking uses a process-global CSV string (tsTsdbRepairDoneVnodeId) that is read/modified during open_fs(). Vnodes are opened concurrently, so this is not thread-safe and can corrupt the buffer or cause incorrect de-dup decisions. Guard accesses with a mutex (or use a concurrent set/bitmap keyed by vgId).

_start_repair_process() references extra_env but the function has no such parameter/variable in scope, so this will raise a NameError at runtime when the helper is used. Add an extra_env parameter (default None) and apply it to env, or remove the dead code path if not needed.

_run_taosd_with_cfg() accepts an extra_env argument but never applies it to the subprocess environment. Either remove the parameter or update the function to merge extra_env into env so callers can reliably inject test-only environment variables.

_run_taosd() uses subprocess.run() without a timeout. Several cases invoke taosd -r ... without -V and could hang if the CLI behavior regresses, which would stall CI. Add a reasonable timeout and include the timeout handling in the assertion helper.

metaMarkForceRepairDone() is never called after a successful meta force repair. Without marking the vnode as repaired, repeated metaOpen() calls in the same process could re-run force repair unexpectedly. After a successful metaForceRepair() (or after metaForceRepairIfShould() returns success), record completion via metaMarkForceRepairDone(TD_VID(pVnode)).

The test docstring says taosd is stopped before running tsdb force repair, but the test doesn't actually stop the running dnode before launching taosd -r .... This can make the test flaky (port already in use / data directory lock) and diverges from the intended scenario. Stop taosd (e.g., tdDnodes.stop(1)) before invoking _run_taosd_with_cfg, and restart in a finally block like the other tests in this file.

dmParseRepairOption() declares const char *arg = argv[index]; but never uses it. This can trigger -Wunused-variable warnings in builds that treat warnings as errors. Remove the unused variable (or use it) to keep the build clean.

metaBackupCurrentMeta() is defined but never called. As a result, meta force repair won't create the external backup directory that the tests (and design notes) expect. Call metaBackupCurrentMeta(pVnode) when metaShouldForceRepair() is true (ideally before any local rename/switch operations) and handle/propagate its error code.
- Introduce new `--repair-target` parameter to replace single-profile options (`--file-type`, `--vnode-id`) - Support multiple repair targets in a single `taosd -r` invocation - Define grammar: `<file-type>:<key>=<value>[:<key>=<value>]...` with file types: meta, tsdb, wal - Enforce validation: requires `-r`, `--mode force`, `--node-type vnode`, and at least one `--repair-target` - Remove backward compatibility for old CLI options, treat them as invalid - Update error messages and test cases to reflect new interface - Centralize parsing in `dmMain.c` with normalized target structures
…ggregated structures - Replace `SArray<SDmRepairTarget>` runtime model with three aggregated structures: `meta` (vnodeId -> strategy), `wal` (vnodeId -> presence), and `tsdb` (vnodeId -> fileId -> strategy) - Update `dmRepair.h` to expose only leaf configurations and dedicated accessors, hiding underlying containers - Modify `metaOpen.c` and `tsdbFS2.c` to use new accessors instead of scanning generic target lists - Update documentation in `findings.md` and `progress.md` to reflect the refined data model - Ensure parser test cases (`test_com_cmdline.py -k repair_cmdline_repair_target`) continue to pass after refactoring

tsdbRepairDropCoreOnTmpFSet() clears/unrefs fset->farr[ftype] before calling tsdbTFileSetEdit() with a TSDB_FOP_REMOVE op. tsdbTFileSetEdit()'s remove path dereferences fset->farr[op->of.type] to unref it, so setting it to NULL here will lead to a NULL dereference (and also double-unref if it were non-NULL). Let tsdbTFileSetEdit() own the unref/NULL assignment (i.e., remove the manual tsdbTFileObjUnref + farr[ftype]=NULL), or apply the edit before mutating fset->farr.

metaForceRepair() has multiple early-return error paths after successfully opening pNewMeta (and/or starting a transaction) that don't close pNewMeta or otherwise clean up the temp meta state. This can leak resources and potentially leave meta_tmp in a partially initialized state. Consider switching to a single goto _exit cleanup path that always metaClose(&pNewMeta) (and aborts/rolls back any started transaction) before returning.

metaMarkForceRepairDone() / tsMetaRepairDoneVnodeId are introduced and used for the “already repaired in this process” check, but the code never calls metaMarkForceRepairDone() after a successful force repair. As a result, the done-list check will never take effect, and the helper itself is currently dead code. Either call metaMarkForceRepairDone(TD_VID(pVnode)) after metaForceRepair() succeeds (so repeated metaOpen() calls don't re-run repair), or remove the unused tracking code.

After a successful repair in metaForceRepairIfShould(), the vnode isn't marked as “repaired” for this process, so a later metaOpen() for the same vnode (e.g., reopen paths) could re-run force repair again. This is especially important since metaForceRepairMatchesVnode() checks tsMetaRepairDoneVnodeId but that list is never updated. Mark the vnode as done on success (or remove the done-list gate entirely).
- Introduce SRepairVnodeOpt structure to encapsulate vnode-specific repair options - Update SDmRepairOption to use vnodeOpt and prepare for mnode/snode support - Adjust cleanup and target insertion functions to work with new structure - Clarify node-type options in comments and add new repair modes (copy, replica)
… flag - Remove 'dnode' from the node-type option comment in dmMain.c as it is no longer supported - Eliminate the global variable generateNewMeta and all its references across dmMain.c and metaOpen.c - Simplify repair option handling by removing unnecessary flag resets - Update code to reflect current supported node types: vnode, mnode, snode

| **Goal:** Add real execution for `taosd -r --mode force --file-type meta` by enhancing the existing `metaGenerateNewMeta()` path so each vnode decides during `metaOpen()` whether it should run force repair, with external backup support and crash-safe local directory switching. | ||

This plan doc includes assistant-specific directions (“For Claude…Use superpowers…”). If the intent is a reusable engineering plan, consider removing those lines or moving them into an AI-specific runbook (e.g., AGENTS.md) to avoid confusing non-AI readers.
- Remove tsMetaRepairDoneVnodeId static variable and related helper functions - Simplify metaShouldForceRepair by directly checking repair flow and vnode options - Eliminate redundant metaForceRepairMatchesVnode function - Improve code clarity by removing unnecessary indirection in repair condition checks
Disable the meta backup step in metaForceRepair by commenting it out with #if 0. This change is likely a temporary measure to allow the repair process to proceed without performing a backup, possibly for debugging or to avoid backup-related failures during forced repairs. The statistics reset step remains active.

metaBackupCurrentMeta() is never executed because the call is wrapped in #if 0 inside metaForceRepair(). This makes the external backup feature effectively disabled and will also break the E2E expectation that a backup directory is created during meta force repair. Please remove the compile-time guard (or gate it on dmRepairHasBackupPath() / repair mode) so backups are actually produced in repair runs.

tsTsdbRepairDoneVnodeId is a process-global mutable buffer used to track which vnodes have been repaired. Vnodes are opened concurrently (see vmOpenVnodes() spawning threads in source/dnode/mgmt/mgmt_vnode/src/vmInt.c), so reads/writes to this global (via tsdbShouldForceRepair() / tsdbMarkForceRepairDone()) can race and corrupt the CSV or cause missed/duplicate repairs. Please make this tracking thread-safe (e.g., a mutex-protected hash/set keyed by vgId, or store the flag on SVnode/STsdb instance) or otherwise ensure the open path is single-threaded in repair mode.

Introduce walShouldDeleteCorruption inline function to conditionally delete corrupted WAL files based on tsWalDeleteOnCorruption flag or dmRepairNeedWalRepair status. This replaces direct checks of tsWalDeleteOnCorruption in walLogEntriesComplete and walCheckAndRepairMeta, enabling more flexible corruption handling that considers both global configuration and vgId-specific repair requirements.

tsTsdbRepairDoneVnodeId is a file-static global that is mutated by tsdbShouldForceRepair() / tsdbMarkForceRepairDone() without synchronization. Vnodes are opened concurrently (multiple threads in vmOpenVnodes), so this is a data race and can corrupt the CSV buffer or lead to repeated/partial dispatch decisions. Please make the “already repaired” state per-vnode/per-STFileSystem (or guard shared state with a mutex/atomic).

walShouldDeleteCorruption() calls dmRepairNeedWalRepair(), but in this PR that symbol is only implemented in the taosd executable (dmMain.c) and in vnodeRepair.c (vnode library). The WAL unit test (walTest) links wal without those objects, so this introduces an undefined symbol at link time for test builds (and any other binary that links wal but not vnode/mgmt). Provide weak/default dmRepair implementations from a library that wal always links (e.g., common), or otherwise ensure the symbol is available wherever wal is used.

This test runs taosd -r ... via _run_taosd_with_cfg() while the dnode is still running (unlike the other tests in this file which stop the dnode first). Starting a second taosd against the same config/data dir is likely to fail (port conflict / file lock / concurrent data access) and makes the test flaky. Stop tdDnodes before invoking the repair process and restart it in a finally block, consistent with test_tsdb_force_repair_dispatches_in_open_fs().
- Add `dmRepairNodeTypeIsVnode()` and `dmRepairModeIsForce()` functions to header and implementation - Introduce `tsdbShouldForceRepair()` and `tsdbForceRepair()` function declarations for TSDB repair logic - Refactor TSDB repair flow to conditionally apply force repair based on node type and mode - Improve repair plan handling with detailed block validation and error reporting
- Implement `tsdbForceRepair` to handle missing or corrupted files in TSDB - Add helper functions for detecting bad files and performing deep scans - Include STT file validation and data part verification mechanisms - Introduce commit change process with proper locking for thread safety - Structure repair operations to maintain data consistency during recovery

tsdbRepair.c currently contains incomplete/invalid C code (e.g., wrong type STFileset, empty initializer SSttBlk *pSttBlk = ;, and a placeholder call to tsdbReadFile(...) with a function signature pasted into the call).

In tsdbForceRepair, the loop calls tsdbForceRepairFileSet(fs, pFileSet, &hasChange) but tsdbForceRepairFileSet is declared with four parameters (pFS, pFileSet, opArr, hasChange).

The current tsdbForceRepair implementation doesn’t print the dispatch marker that the new pytest cases assert on (e.g., "tsdb force repair dispatch"). The only printf/marker emission is in the #if 0 block below, so the tests will fail even if this compiles. Please either re-enable the implemented dispatch/logging path or update the tests to assert on the actual output produced by the enabled repair flow.

This test runs taosd -r --mode force ... without stopping the existing tdDnodes taosd instance first. Launching a second taosd process against the same data/cfg directories can fail due to locks or (worse) corrupt state. Consider stopping tdDnodes (as done in other repair tests) before invoking the repair-mode taosd, then restarting in finally.
Add deep scanning logic to tsdbRepair.c to detect and fix corrupted data blocks within brin blocks. The new tsdbDeepScanAndFixDataPart function reads brin blocks, validates data blocks, and skips corrupted entries. This enhances data integrity during repair operations by isolating and handling bad data segments without affecting the entire dataset.
- Change default TSDB repair strategy from `shallow_repair` to `drop_invalid_only` - Rename TSDB repair strategies: `shallow_repair` → `drop_invalid_only`, `deep_repair` → `head_only_rebuild` - Add new `full_rebuild` strategy for complete core data reconstruction - Update documentation in both English and Chinese versions with detailed strategy descriptions - Modify internal enum values and code references to reflect new strategy naming - Update command examples to use new strategy names - Add test configurations for new repair functionality The changes provide more granular control over TSDB repair operations with clearer strategy semantics.

tsdbRepairTest is added unconditionally, but tsdbRepairTest.cpp includes/uses POSIX-only APIs (e.g. sys/syscall.h, mkstemp, SYS_close). This will fail to build on Windows. Suggest guarding the ADD_EXECUTABLE(tsdbRepairTest ...) block with IF(NOT TD_WINDOWS) (similar to tqTest) or providing a Windows-compatible implementation.

The metaBackupCurrentMeta function is defined but the call site is wrapped in #if 0 (line 558), so it's dead code. If this is intentional for a future phase, consider adding a comment explaining when it will be enabled; otherwise remove it to avoid confusion.

In metaForceRepair, if metaOpenImpl or metaBegin fails, pNewMeta is leaked (it's opened but never closed on the error path). Similarly, if metaForceRepairFromUid or metaForceRepairFromRedo fails at lines 582-591, pNewMeta is not closed before returning.

dmFinalizeRepairOption returns 1 (line 788) for TSDB_CODE_OPS_NOT_SUPPORT, which is an ad-hoc non-standard error code that gets propagated from dmParseArgs. This breaks the convention where the function otherwise returns TSDB_CODE_* values. The caller in mainWindows checks code != 0 and may misinterpret this as an unrelated error. Consider returning a proper TSDB_CODE_* constant instead.

The _prepare_stt_fixture method accepts a total_rows=4000 parameter but never uses it — the actual row count is hardcoded to 200 (two batches of 100 + 1 extra row, and row_count is returned as 200). The total_rows parameter is misleading and should either be removed or actually used.
