ID: 47204 User updated by: a...@php.net Reported By: a...@php.net Status: Open Bug Type: Feature/Change Request Operating System: Irrelevant PHP Version: 5.3 Assigned To: srinatar New Comment:
While adding PHP-side support for CURLOPT_IOCTLFUNCTION is indeed a feature request, complete inability for curl extension to handle redirects / digest authentication when using CURLOPT_INFILE (CURLOPT_READDATA) looks like a genuine bug to me. The problem lies with Curl extension registering a custom callback curl_read() as CURLOPT_READFUNCTION (it handles both reading from a stream provided as CURLOPT_INFILE and calling PHP callback provided as CURLOPT_READFUNCTION) but failing to implement custom callback for rewinding the data, at least for the case when stream is used.

Doesn't work *at all* with POST due to PHP bug #47204, workaround needed. ------------------------------------------------------------------------ [2009-09-24 19:26:54] srina...@php.net since, this is a feature, this will probably apply only for 5.3 onwards. ------------------------------------------------------------------------ [2009-09-20 17:31:31] j...@php.net Recategorized, this is not a bug. ------------------------------------------------------------------------ [2009-09-20 08:47:21] a...@php.net Marking this as "cURL related" to increase visibility. ------------------------------------------------------------------------ [2009-06-22 16:04:07] felix-php at 7val dot com This problem not only occurs when negotiating HTTP Auth. It's much easier to provoke by posting to a URL that answers with a redirect. Any valid HTTP redirect (be it 302, 303 or 307) lets curl rewind its request body before following the Location header. Thus CURLOPT_READFUNCTION is pretty useless for accessing web servers in the wild. Therefore I think it's rather a bug than a feature. Reproduce: Both examples above with an extra curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); and a URL answering with a redirect. (Tested with PHP 5.2.9 and curl 7.19.5) Proposal: Instead of adding CURLOPT_IOCTLFUNCTION to the PHP extension, this bug could be fixed by adding the CURLTOP_SEEKFUNCTION functionality. If set, curl uses this to rewind the body, too (see Curl_readrewind() in transfer.c). But the seek_func callback is also used for resuming uploads which might be a nice side effect. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
