Edit report at https://bugs.php.net/bug.php?id=78312&edit=1 ID: 78312 User updated by: oleg at andreyev dot lv Reported by: oleg at andreyev dot lv Summary: Different results between 7.3.7 and 7.4 -Status: Feedback +Status: Assigned Type: Documentation Problem Package: PCRE related Operating System: Linux PHP Version: 7.4Git-2019-07-19 (Git) Assigned To: sjon Block user comment: N Private report: N New Comment: As Nikita mentioned only UNMATCHED_AS_NULL is covered and OFFSET_CAPTURE was missed (probably other cases are also missed) Previous Comments: ------------------------------------------------------------------------ [2019-07-19 15:53:26] nikic@php.net This specific case doesn't seem to be mentioned in UPGRADING (it currently only discusses the UNMATCHED_AS_NULL case), so that at least should be added. ------------------------------------------------------------------------ [2019-07-19 14:44:57] requinix@php.net It will be documented in the function's Changelog and the 7.4 migration guide. That is how these sorts of changes are always handled. Anyone blindly upgrading their codebase to 7.4, or any new version series, is shooting themselves in the foot. Is that acceptable? If not then what are you asking for to happen? ------------------------------------------------------------------------ [2019-07-19 14:41:36] oleg at andreyev dot lv This is something that I would like to see highlighted because it can affect all templating engines who has some Lexers e.g.: Twig ------------------------------------------------------------------------ [2019-07-19 14:12:17] requinix@php.net What's more, this is mentioned by NEWS and UPGRADING so it's not like this change has been forgotten... ------------------------------------------------------------------------ [2019-07-19 12:59:00] sjon@php.net Actually the output in 7.4 seems to be correct as before the offset was completely missing. This was fixed in Bug #73948 also - the output in 7.4 actually matches the documentation better - don't you agree? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
