Bug #80726 [Opn]: With any PHP 8 version I get crash running more than one CLI

Edit report at https://bugs.php.net/bug.php?id=80726&edit=1 ID: 80726 User updated by: rfcastro at porto dot ucp dot pt Reported by: rfcastro at porto dot ucp dot pt Summary: With any PHP 8 version I get crash running more than one CLI Status: Open Type: Bug Package: JIT Operating System: Windows Server 2012 R2 PHP Version: 8.0.2 Block user comment: N Private report: N New Comment: The multi-run php cli seemed to go away like you said I still get once a week perhaps this error with JIT: msodbcsql17.dll . I did think perhaps it's when the code runs a bit faster, it's an synchronizer and when it doesn't find any changes, sometimes I get this error. I was thinking perhaps it's triggering the same problem the multi cache. I have updated that DLL but it came back again. Perhaps some JIT buffer overflow? The code is working 24 hours none stop till I hit this error. Event log: Faulting application name: php.exe, version: 8.0.2.0, time stamp: 0x601adf99 Faulting module name: msodbcsql17.dll, version: 2017.177.1.1, time stamp: 0x6001e170 Exception code: 0xc0000005 Fault offset: 0x0000000000029a76 Faulting process id: 0xadc Faulting application start time: 0x01d701c93dd362e3 Faulting application path: C:\Program Files\PHP\v8.0.2\php.exe Faulting module path: C:\Windows\system32\msodbcsql17.dll Do you want me to open a new bug or perhaps this has something to do with the opcache? Previous Comments: ------------------------------------------------------------------------ [2021-02-10 13:38:36] rfcastro at porto dot ucp dot pt So for Windows I should set in the PHP.INI opcache.cache_id=1 so any code will run always in opcache.cache_id=1 And manual if I have to run multi-codes at the same time, I should set each extra one with a opcache.cache_id=2 and opcache.cache_id=3, etc... Is this correct? And thank you for your time. ------------------------------------------------------------------------ [2021-02-10 13:34:55] cmb@php.net opcache.cache_id defaults to an empty string (the documentation is wrong about the "1" default). This default is different from any other ID. Note that ID is an arbitrary *string* (the documentation is correct about that). ------------------------------------------------------------------------ [2021-02-10 12:17:58] rfcastro at porto dot ucp dot pt Right now I have it working placing the opcache.cache_id=2 on runtime on the main running script and the rest I have no opcache.cache_id, so I was guessing it would use 1 by default. I see now in the PHP.ini there is an "opcache.cache_id=" commented. So should I place an opcache.cache_id=1 in the PHP.INI, or will it always used by default the opcache.cache_id=1 and since my main running code is on opcache.cache_id=2 it will work. ------------------------------------------------------------------------ [2021-02-10 12:09:19] cmb@php.net On non Windows systems, OPcache instances are never shared between unrelated PHP processes; only forked childs share the instance with their parent. Since there is FPM, this model works very well. On Windows, there is no FPM (and generally no fork(3)), so all PHP processes using the same PHP version and SAPI share an OPcache instance (until there is no more PHP process within that group, in which case the OPcache instance is destroyed). This is required to have only a single OPcache instance for (F)CGI. This does not really make sense for typical CLI scripts, but there may be cases where this is desired even for CLI. Thus, the opcache.cache_id INI option has been introduced, so that it's possible to control the sharing of instances. It might be sensible to automatically use separate OPcache instances for CLI, if opcache.cache_id is not set, but that would be a behavioral change. I wonder, though, whether different OPcache instances are supposed to be required in your case, or whether there is a bug in the JIT implementation. ------------------------------------------------------------------------ [2021-02-10 10:26:20] rfcastro at porto dot ucp dot pt Yes, using the two different caches works. But is this possible automatically? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
