#24725 [Asn]: cURL CURLOPT_ENCODING does not appear to work
ID: 24725 User updated by: Julian_bond at voidstar dot com Reported By: Julian_bond at voidstar dot com Status: Assigned Bug Type: cURL related Operating System: Redhat 7.3 and MS Win PHP Version: 4.3.2 Assigned To: edink New Comment: php4-STABLE-200307220930 To confirm. The bug fix worked and HTTP_ACCEPT_ENCODING is now generated. On Unix with zlib bound into curl, it's correctly requesting gzip, deflate and decoding the result. On Windows with php_curl, it's generating identity as the only supported compression. Almost certainly because php_curl.dll doesn't yet bind zlib. Thanks guys. Almost there. Previous Comments: [2003-07-20 10:54:37] Julian_bond at voidstar dot com Got there eventually. I can confirm that the snapshot still has the same problem on *nix redhat/7.3 php/4.3.3RC2-dev libcurl/7.10.5 OpenSSL/0.9.6b zlib/1.1.4 php4-STABLE-200307201330 From the comments below, it sounds like the bug has been found. Happy to test it once it's in the snapshot. [2003-07-20 10:22:54] [EMAIL PROTECTED] There was a small bug in the php curl, but it's fixed now. Now the encoding works as long as libcurl is linked with zlib. (Edin, is the libcurl used by win32 stuff linked with it??) [2003-07-20 08:42:16] [EMAIL PROTECTED] Just a build issue with curl libs.

#24725 [NEW]: cURL CURLOPT_ENCODING does not appear to work
From: Julian_bond at voidstar dot com Operating system: Redhat 7.3 and MS Win PHP version: 4.3.2 PHP Bug Type: cURL related Bug description: cURL CURLOPT_ENCODING does not appear to work Description: Redhat/7.3 php/4.3.2 libcurl/7.10.5 OpenSSL/0.9.6b zlib/1.1.4 MS Win php/4.3.2 libcurl/7.10.5 OpenSSL/0.9.7b MS Win php/4.3.3RC1 libcurl/7.10.5 OpenSSL/0.9.7b See also: http://bugs.php.net/bug.php?id=23048 http://bugs.php.net/bug.php?id=21995 http://bugs.php.net/bug.php?id=23702 According to the libcurl docuentation, curl_setopt ($ch, CURLOPT_ENCODING,); should generate a header HTTP_ACCEPT_ENCODING: gzip,deflate And then autodecode the returned data if the remote server supports compression. However in the above three PHP releases it never does. Reading the three bug reports above, it appears that support for this option call may have been added to php 4.3.2 and so the problem is currently viewed as a documentation problem. However after repeated tests, it still appears to be missing from either php and/or libcurl and hence this bug report. The libcurl crew deny responsibility(!) and point at the php implementation. Using curl from the command line with the --compressed option I can see the header and auto-decoding working but I don't have the facilities to check the libcurl library except from inside php. The libcurl readme http://cvs.php.net/co.php/curl/lib/README.encoding?r=1.3 says that The library zlib is required for this feature. but as can be seen above from the version report, php_curl.dll for windows does not appear to bind the zlib library, so even if the parameter option is being passed to libcurl, it probably wouldn't work anyway. Reproduce code: --- $ch = curl_init(http://www.voidstar.com/temp/accept.php;); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_ENCODING,); curl_setopt ($ch, CURLOPT_HEADER, 1); $data = curl_exec($ch); curl_close ($ch); print pre . htmlentities($data) . /pre; Expected result: http://www.voidstar.com/temp/accept.php prints the headers it receives. It's running on a server with zlib support compiled into php and zlib.output_compression = on This can be seen by using a browser that supports gzip to navigate to the url above. In this case the header can be seen. The reproduce code above should generate the accept_encoding header which should then result in it being mirrored back to curl which then displays it.
