Thanks. Previous Comments: ------------------------------------------------------------------------ [2016-09-19 07:49:02] maggus dot staab at googlemail dot com Thx anatol for your patch! I am not sure what the easiest way is to get a custom php7 build running with this patch included. Do I have to build/make/compile it on my machine? ------------------------------------------------------------------------ [2016-09-16 13:56:46] ab@php.net Markus, could you check the attached patch please? Besides your actual repro case, with the data size < 8k, > 16k and the rest of your app. Thanks. ------------------------------------------------------------------------ [2016-09-16 13:52:51] ab@php.net The following patch has been added/updated: Patch Name: bug73037.try.2.patch Revision: 1474033971 URL: https://bugs.php.net/patch-display.php?bug=73037&patch=bug73037.try.2.patch&revision=1474033971 ------------------------------------------------------------------------ [2016-09-15 15:42:03] ab@php.net I repro the case with gzip compression. But from what i could debug, it looks rather like an issue with the exact case, not with the streams. The compressed data arrives, but the wrapping stream doesn't eat all the uncompressed buffer. Right now it looks like an issue with XML parser in conjunction with streams. The internal stream buffer is 8192 bytes, any data smaller than that seems to come through. Also, a simple snippet without XML parser works, too. Like $fd = fopen("php://input", "rb"); stream_filter_append($fd, 'zlib.inflate', STREAM_FILTER_READ, array('window' => 0x2f)); $in = ""; while (!feof($fd)) { $in .= fread($fd, 1024); } fclose($fd); I was able to track this down to PHP 5.5 already. Digging further on this. Bob, i currently don't see, how the other snippet is connected to this. Works in both 5 and 7 on my side. Maybe it's also about buffered enclosed stream. Didn't try anything else, but google seems to deliver the whole page, though always different size. Thanks. ------------------------------------------------------------------------ [2016-09-12 12:17:54] maggus dot staab at googlemail dot com I can re-produce the issue with opcache, blackfire disabled. same issue without those extensions. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
