Bug #76535 [Opn]: Opcache does not replay compile-time warnings

Edit report at https://bugs.php.net/bug.php?id=76535&edit=1 ID: 76535 Updated by: nikic@php.net Reported by: nikic@php.net Summary: Opcache does not replay compile-time warnings Status: Open Type: Bug Package: opcache PHP Version: Irrelevant Block user comment: N Private report: N New Comment: If there is a performance concern, I'd be fine with having this behind an ini flag like opcache.replay_warnings=1. Previous Comments: ------------------------------------------------------------------------ [2018-06-28 09:36:45] laruence@php.net I mean that if there is warning, people(php users) should fix it in there own codes... anyway, I understand your point, maybe just disable opcache while test warnings? I was concern that we need pay some costs, like performance reduce to achieve this... like save_cwd... if it cost little, then I have no problems.... ------------------------------------------------------------------------ [2018-06-28 08:49:54] nikic@php.net @laruence: My main use for this is testing. To test file cache, you need to run something like sapi/cli/php run-tests.php -P -c php.ini -d opcache.file_cache=/tmp Zend/ sapi/cli/php run-tests.php -P -c php.ini -d opcache.file_cache=/tmp -d opcache.validate_timestamps=0 Zend/ However, this causes a lot of test failures even if every thing works "correctly", due to differences in warnings. Unless by killing warnings you mean that we have plans to remove them from PHP entirely, I think it makes sense to implement this. ------------------------------------------------------------------------ [2018-06-28 04:40:17] laruence@php.net on the other hand, warnings should be killed anyway.... so I am not sure if it is worthy to do this... ------------------------------------------------------------------------ [2018-06-27 09:00:40] nikic@php.net Description: ------------ If opcache is enabled, non-fatal compile-time diagnostics are only emitted on first compile, not when the file is fetched from cache. It would be nice if we would register an error handler that records all the emitted warnings and then emit them when the file is loaded. Main motivation is testing: Currently if you want to test a file cache compile&load cycle, you have to filter out many tests that always fail due to warning differences. It's hard to spot regressions because of that. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76535&edit=1
