#29045 [Sus]: gzopen for URL

ID: 29045 Updated by: pollita@php.net Reported By: fcartegnie at nordnet dot fr Status: Suspended Bug Type: Documentation problem Operating System: Linux PHP Version: 4.3.6 Assigned To: pollita New Comment: Wez needs to chime in on this... I stated that it wouldn't work for http (with or without the patch) because I thought we had disabled shrinking the chunk_size to 1 while reading into the HTTP headers (for performance reasons). Looking back at the code I see that the temporary shift into small chuck sizes *IS* enabled when the STREAM_WILL_CAST flag is set (which it is for the zlib fopen wrapper). Maybe it was the conditional set based on the option flag that was the compromise... in which case I'd say: Go ahead and use fopen('compress.zlib://http://blah...',... but the patch provided for gzopen() seems completely unnecessary. Previous Comments: ------------------------------------------------------------------------ [2004-07-07 16:16:46] derick@php.net compress.zlib://http://host.file.gz should work fine in php 4, not? include "compress.zlib://file.php.gz"; works too ;-) ------------------------------------------------------------------------ [2004-07-07 16:12:31] pollita@php.net compress.zlib://host/path isn't actually valid. What is valid however (as of PHP5) is: $fp = fopen('http://host/path/file.gz', 'r'); /* Maybe a small fread() here to consume gzip headers, I don't recall if they're sent with deflated content */ stream_filter_append($fp, 'zlib.inflate'); Note: For PHP 5.0 you need PECL package zlib_filter, it'll be rolled into the core in PHP 5.1 . The patch supplied above needs further review as I see a big potential for zlib stream errors with the read buffer blocks that come in with the headers. ------------------------------------------------------------------------ [2004-07-07 14:39:51] fcartegnie at nordnet dot fr compress.zlib://http:// seems to work Maybe we could add some deprecation/pointer info in the documentation of gzopen() Changing for documentation problem ------------------------------------------------------------------------ [2004-07-07 14:33:40] fcartegnie at nordnet dot fr I did not see this syntax in the documentation. fopen("compress.zlib://host.com/file.gz") How would you specify HTTP or FTP ? ------------------------------------------------------------------------ [2004-07-07 13:09:46] derick@php.net Why not use fopen("compress.zlib://host.com/file.gz") and all the other normal file operations? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
