support for Centos 7 (Scientific Unix 7)

[andrewmilkowski]

Hello, trying this client on Scientific Unix 7 (kernel is based off Centos 7) based on the write up I see only Ubuntu and Debian support for HHVM client (specific versions listed are "Currently tested on 64-bit Ubuntu 14.04 LTS against HHVM 3.7.2"

HHVM 3.7.2 and HHVM 3.8.2 does succeed on Centos 7 without a problem

Is there a plan to support Centos 7 OS and approximate timing for this... running master version of this client (aerospike-client-hhvm) with aerospike aerospike-server-community-3.5.14-el6 version and aerospike client c library ( 3.1.16 ) produce segment fault exception

below is HHVM issue regarding HHVM 3.7.2 (my hope is that support for this client will be enabled for higher versions of HHVM as this git repo is suggesting will happen)

below ticket has been canceled, issue was with the artifacts. fresh new git pull and checkout assemble binaries just fine.. issue is with aerospike-client-hhvm alone
facebook/hhvm#5692

[rbotzer]

Hi Andrew. We intend to support all 64-bit Linux variants, but we'll probably do it once HHVM does so as well. Once HHVM reaches the next LTS (3.9.0) we will push to get wider support, and until then we intend to continue testing with resent releases on Ubuntu 14.04. For example, HHVM 3.8.0 was released just a couple of hours ago.

[andrewmilkowski]

thank you @rbotzer , it is imperative for my org, that all interfaces are as stable as they possibly can as we intend to use this in high volume production environment

put a watch on this topic (and facebook HHVM), meantime re-pulling latest master from here and attempting HHVM 3.8.0 assembly

thanks for your fast feedback on this, we look forward to speed gains provided by this client...

[andrewmilkowski]

@rbotzer HHVM 3.8.0 assembly fails on Centos 7 so this is pretty much a blocker for us.. for now

[rbotzer]

Did you look at their instructions for using other pre-built packages or building HHVM manually?

[andrewmilkowski]

yes, git master succeeds... then git checkout HHVM-3.8 and below and error

cmake -DCMAKE_INSTALL_PREFIX=/opt/local/src/git/facebook/hhvm/dist .
make -j$(($(nproc)+1)) # make with CORE_COUNT+1 threads, that would be fast. You may run out of RAM

./hphp/hhvm/hhvm --version
make install

let me do fresh check out fresh new copy and re-assembly as sanity check

[andrewmilkowski]

@rbotzer fresh new git clone (and git checkout HHVM-3.8 from within), did the trick... HVVM-3.8 is assembling (pass 48 step error) then I will tie it into this areospike client and repeat the test.. (must have been old artifacts) appreciate it ...

[andrewmilkowski]

• actually hhvm does not start file (daemon mode) *... hold a sec investigating

@rbotzer , using HHVM-3.8 on Centos 7, so HHVM starts up fine: below is command line process list and php.ini used

1. /opt/local/src/git/facebook/hhvm/dist/bin/hhvm --config /etc/hhvm/server.ini --mode daemon -vServer.Type=fastcgi -vServer.Port=9000
2. /etc/hhvm/server.ini :

pid = /var/run/hhvm/hhvm.pid

hhvm.server.port = 9000
hhvm.server.type = fastcgi
hhvm.server.ip = 127.0.0.1
hhvm.server.default_document = index.php
hhvm.log.use_log_file = true
hhvm.log.header = true
hhvm.log.file = /var/log/hhvm/error.log
hhvm.repo.central.path = /var/run/hhvm/hhvm.hhbc
hhvm.server.thread_count = 40
hhvm.server.expose_hphp = false
hhvm.server.request_timeout_seconds = 8
hhvm.repo.authoritative = true
hhvm.extensions[] = /opt/local/src/git/aerospike/aerospike-client-hhvm/dist/lib64/hhvm/extensions/20150212/aerospike-hhvm.so

[amilkowski@localhost aerospike]$ ps aux | grep hhvm
root 101539 0.0 0.0 210744 3448 pts/1 S+ 18:30 0:00 sudo tail -f /var/log/hhvm/error.log

amilkow+ 106403 0.0 0.0 112648 972 pts/2 S+ 18:34 0:00 grep --color=auto hhvm

then doing below causes "Seg Fault"

[amilkowski@localhost aerospike]$ pwd
/opt/local/src/git/aerospike/aerospike-client-hhvm/src/aerospike
[amilkowski@localhost aerospike]$ cp tests/aerospike.inc tests/aerospike.local.inc

[andrewmilkowski]

@rbotzer , ok sorry about.. have the "use case"

HHVM by itself works perfect on Centos 7 with fastcgi, sample php info page displays "PHP Version 5.6.99-hhvm"

iff/when I add aerospike extension such as below, segment fault results, so we can not use Centos 7 with this solution.. (for now) is there any other help I can yield to trace Centos 7 issue @rbotzer , such as dump analysis , otherwise it is unfortunate.. speed ups would be great for this client/driver...

hhvm.extensions[] = /opt/local/src/git/aerospike/aerospike-client-hhvm/dist/lib64/hhvm/extensions/20150212/aerospike-hhvm.so

[rbotzer]

Please echo that stack trace file - that will help.

[andrewmilkowski]

empty, nothing following "PHP Stacktrace"

also for reference apache2 server is running with fastcgi (installed via these simplest possible instruction, sorry for Spanish. but it was simplest bare bone I could find: https://gist.github.com/marciopaiva/5c8087e53691d50a046b)

command line was:

/opt/local/src/git/facebook/hhvm/dist/bin/hhvm --config /etc/hhvm/server.ini --mode daemon -vServer.Type=fastcgi -vServer.Port=9000

HHVM itself supports Centos 7

just checked hhvm version, still on the wrong one, HipHop VM 3.9.0-dev, making sure it is 3.8.0 and retesting

isolated, SIGINT to these lines of code (commented them out) extension is loaded, obviously you need these registrations, but hopefully helps troubleshooting @rbotzer

something very likely connects to "EXTENSION_CONSTANTS_SIZE" being incorrect

class AerospikeExtension : public Extension {
    public:
        AerospikeExtension(): Extension("aerospike", "1.0") {}
        void moduleInit() override
        {

/*
for (uint32_t i = 0; i <= EXTENSION_CONSTANTS_SIZE; i++) {
Native::registerClassConstant(s_Aerospike.get(),
StaticString(extension_constants[i].constant_name).get(),
extension_constants[i].constant_no);
}
*/

[rbotzer]

@andrewmilkowski it does help, thanks.

[andrewmilkowski]

appreciate it!, this extension you wrote would be great performance boost for us as you can imagine, anything else you need shoot message immediate, will respond right back

thanks so much
