Webman fail with php8.1

[joanhey]

Hi, as the ppa:ondrej/php include now php8.1-rc5, I'm testing the frameworks for the benchmark.

Workerman is working OK, but Webman is failing. The worst thing, it's that don't show any error in the first run, only: Verifying test query for webman caused an exception: ('Connection aborted.', BadStatusLine('No status line received - the server has closed the connection',)) that come from the test.

In the second run, give me the same error and webman: worker[webman:43] exit with status 139. That look like a segmentation fault.

But will be good if webman try to return a better error. PHP8.1 final will be released 25th from this month.

Hi joanhey, thank you for your post.

webman: worker[webman:43] exit with status 139. That look like a segmentation fault.

Yes, you are right, it is a segmentation fault. That means php8.1-rc5 has a bug.

But will be good if webman try to return a better error.

When a segment error occurs, the process is forced to exit and all connections are destroyed. PHP code can't catch this error or control it, so there's basically no way to give users better error info.

Later I will try to find out which code triggered this crash.

Plain Workerman and kumbiaphp with workerman for now work OK with php8.1. Trying with more frameworks now.

Curiously kumbia with nginx fail for preg_match() but not with workerman that is also using preg_match() exactly egual.

[walkor]

preg_match(): Compilation failed: unrecognised compile-time option bit(s) at offset 0 in file /root/FrameworkBenchmarks/frameworks/PHP/webman/vendor/workerman/workerman/Worker.php on line 1056

preg_match_all(): Compilation failed: unrecognised compile-time option bit(s) at offset 0 in file /root/FrameworkBenchmarks/frameworks/PHP/webman/vendor/workerman/workerman/Worker.php on line 794

PHP Warning: preg_split(): Compilation failed: unrecognised compile-time option bit(s) at offset 0 in /root/FrameworkBenchmarks/frameworks/PHP/webman/vendor/nikic/fast-route/src/RouteParser/Std.php on line 31

Warning: preg_replace(): Compilation failed: unrecognised compile-time option bit(s) at offset 0 in Standard input code on line 1252 ( Similar error with composer too)

There are some warnings for preg_* with php8.1 - RC5. Webman required nikic/fast-route which broken with preg_split too . I think php8.1-rc5 changed something with regular expression . I decided to wait for the official release of php8.1 and then decide whether to fix preg_related issues.

[joanhey]

Yes, exist a problem with preg_*, but other frameworks show the error, but not Webman. Perhaps to see the errors you are usingstream_select()`, but now it's the moment to try to show the errors when exist a php problem using another ext event loop.

[walkor]

Ok, I will fix it later.

I find out the key, when php8.1-dev installed the preg_* has no errors that why webman or workerman not show preg_* errors.

[joanhey]

Kumbiaphp-workerman pass the tests, but with errors. ~As Kumbia show more info, perhaps will be useful to help in finding the problem:~

SORRY: This error is normal (bad url). but still exist the problem with the memory.

Also I update the ini with memory_limit = 1024M from the before 512M, but still eat all the memory.

I don't know from where is the problem for now: php, libevent or workerman. Perhaps together we can find the problem.

https://github.com/php/php-src/blob/php-8.1.0RC6/UPGRADING

[joanhey]

~As the errors all point to the include(), perhaps is a problem with the new Inheritance Cache in CLI mode. https://externals.io/message/113091~

[joanhey]

Tried disabling JIT and OPCache, but the errors persist.

Checking the libevent extension issues, I don't find anything relevant to this problem. Well perhaps issue 69. https://bitbucket.org/osmanov/pecl-event/issues

[walkor]

It's strange, I just ran it, but I didn't see that errors.

[joanhey]

Kumbia only fail with kumbiaphp-workerma-mysql (using the ORM).

And only in the update test in the tfb --mode verify. Using tfb --mode debug work perfect without errors.

And show the same error than webman: in /run/ .log worker[none:13] exit with status 139 in the output: Verifying test update for kumbiaphp-workerman-mysql caused an exception: ('Connection aborted.', BadStatusLine('No status line received - the server has closed the connection',))

[joanhey]

I will check the update test code, as the problem is the same than with webman.

Comet that use workerman have another error: Deprecated: str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in /comet/vendor/workerman/workerman/Protocols/Http/Request.php on line 166

That error is normal in php8.1

But also have some 139:

webman: worker[webman:44] exit with status 139

That seems opcache's bug in php8.1.0RC6, when I disabled opcache by opcache.enable_cli=0 the error disappeared for webman and kumbiaphp-workerman-mysql.

[joanhey]

Without opcache is working. With opcache and without jit fail.

And in the actual run kumbia-workeman, that pass the verify, had failed in all the tests: [kumbiaphp-workerman] failed: json db query fortune update plaintext In local, run the benchmark without any error.

In about 2 days we could check which fw passed, and watch the logs. We need to isolate this bug.

PD: php 8.1 is really fast. Cakephp and laravel with fastcgi are about 100% faster in all tests.

[joanhey]

Mixphp-workerman passed the run with mysql (orm) and postgresql raw. The performance gain is about 2-3%.

[joanhey]

Ubiquity-workerman and workerman plain both worked OK.

Kumbiaphp-workerman failed with the same status 139: https://tfb-status.techempower.com/unzip/results.2021-11-18-19-10-12-391.zip/results/20211114055625/kumbiaphp-workerman/run/kumbiaphp-workerman.log

But in local worked without any problem. Update: in the last run worked without problems.

[joanhey]

Tested with event 3.0.7RC1 (beta) and the same problem.

[joanhey]

Tested without event extension and the same problem. So the problem will be in the opcache in php 8.1.

Well, Webman pass the plaintext and fail with the others.

[joanhey]

With only 1 process it's working OK.
