I have the same problem /var/tmp/portage/dev-lang/php-5.2.6/work/php-5.2.6/main/streams/streams.c(390) : Stream of type 'STDIO' 0x8386378 (path:./storage/706e362fa415aa530247b0c4a372b249) was not closed What infomation you need too? ------------------------------------------------------------------------ [2008-03-25 13:33:31] jani@php.net Ilia, the fix propably wasn't quite right, and I get this with the example script: [jani@localhost ~]$ /home/jani/src/build/php_5_2/sapi/cli/php t.php Warning: file_put_contents(compress.zlib:///tmp/hello.txt.gz): failed to open stream: Inappropriate ioctl for device in /home/jani/t.php on line 5 bool(false) int(0) string(0) "" /home/jani/src/php-5.2/main/streams/streams.c(390) : Stream of type 'STDIO' 0x9504c4c (path:/tmp/hello.txt.gz) was not closed [Tue Mar 25 15:30:11 2008] Script: 't.php' /home/jani/src/php-5.2/main/streams/streams.c(227) : Freeing 0x09504C4C (128 bytes), script=t.php /home/jani/src/php-5.2/ext/zlib/zlib_fopen_wrapper.c(127) : Actual location (location was relayed) === Total 1 memory leaks detected === ------------------------------------------------------------------------ [2008-03-22 03:06:49] david at acz dot org Description: ------------ When passing LOCK_EX to file_put_contents() using a "compress.zlib" stream, the function creates a valid gzip file (non-empty) containing zero un-compressed bytes (gunzip outputs nothing) and returns false. This was reported in #42468, but wasn't actually fixed. The function needs to fail BEFORE it opens (and destroys) the output file. Reproduce code: --------------- <? $name = "/tmp/hello.txt.gz"; $file = "compress.zlib://" . $name; var_dump(file_put_contents($file, "hello", LOCK_EX)); var_dump(filesize($name)); var_dump(file_get_contents($file)); ?> Expected result: ---------------- int(5) int(31) string(5) "hello" Actual result: -------------- bool(false) int(26) string(0) "" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=44501&edit=1
