Bug #36514 [Com]: ob_gzhandler() issue

Edit report at https://bugs.php.net/bug.php?id=36514&edit=1 ID: 36514 Comment by: john dot nicholls at eagleeye dot com Reported by: lunter at interia dot pl Summary: ob_gzhandler() issue Status: No Feedback Type: Bug Package: Output Control Operating System: winXP PHP Version: 5.1.2 Assigned To: mike Block user comment: N Private report: N New Comment: The test cases already provided remain valid. Using PHP 5.6.40 on CentOS Linux release 7.7.1908 (Core), we experience the same issue. It has proven possible however, to work around the bug by using a second level of output buffering: // script 3 <? ob_start('ob_gzhandler'); ob_start(); print(str_repeat('a',5)); ob_end_clean(); print(str_repeat('b',5)); ob_end_flush(); ?> Previous Comments: ------------------------------------------------------------------------ [2012-03-16 09:27:59] mike@php.net No feedback was provided.

It's quite clear that the ob_gzhandler output is missing the gzip header but is otherwise similar (identical except for the occasional 4-byte block, I'm guessing those are checksums or something). So Mark would seem to be right that the GZIP header gets thrown out by ob_clean() and doesn't come back. ------------------------------------------------------------------------ [2010-06-18 22:43:26] jani@php.net Assigned to someone who cares. ------------------------------------------------------------------------ [2009-08-18 14:56:59] jani@php.net Need to investigate if this is a) fixed in HEAD by the new output code (or fix it if not) and b) if it's actually fixable somehow in 5.* branches. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
