No idea why/what the underlying reason for the lack of resolution is, especially given all of the excellent suggestions. But, as we have just run-up against this bug, and it has become a real show stopper for us, we are sadly left with no alternative but to migrate our entire web-server fleet to Nginx.

Thanks a lot for the pointer Yann! So, unveiling all my ignorance about the CL header, IIUC when TE:chunked is not used (in a POST request), the client sends the CL header and then mod_proxy_fcgi is able to populate the CGI's CONTENT_LENGTH header easily, but when TE:chunked is used, there is no quick way to get the number of bytes in the body/payload unless something explicitly counts them. So mod_proxy_http's trick is to pull the body/payload from the input chain, and then use it later on to easily count the CL. -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: bugs-unsubscr...@httpd.apache.org For additional commands, e-mail: bugs-h...@httpd.apache.org

I checked and indeed it is implemented only in _http, not _fcgi, but it is a good pointer! After reading a bit the code, I'd add a condition in mod_proxy_fcgi's dispatch() to add the missing CL if TE:chunked is present, but I am not super clear if it is possible to do such a thing from the data in request_req. It seems to me that it shouldn't be super difficult but I need to read more code before adding a meaningful code change.

Hi Rainer,
I can repro with this simple php script:
getBody();
echo($request);
echo("\n");
?>
1) curl -k https://localhost/receiveChunk.php --header "Pragma: no-cache"
--header -X POST -d "blablablabla"
POST /receiveChunk.php HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Content-Length: 12
Pragma: no-cache
Accept: */*
User-Agent: curl/7.52.1
Host: localhost
blablablabla
2) curl -k https://localhost/receiveChunk.php --header "Pragma: no-cache"
--header "Transfer-Encoding: chunked" -X POST -d "blablablabla"
POST /receiveChunk.php HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Transfer-Encoding: chunked
Pragma: no-cache
Accept: */*
User-Agent: curl/7.52.1
Host: localhost
I also added "SetEnv proxy-sendctl" to my vhost config but didn't observe any
difference.
With a bit more detail, I also added LogLevel proxy_fcgi:trace8 and spotted the
following log only in the first case:

https://bz.apache.org/bugzilla/show_bug.cgi?id=57087 --- Comment #4 from Steffen Moser --- We've just encountered this problem even with Nextcloud 13.0.5 on Apache 2.4.33 and PHP-FPM 7.1.17, OS: Oracle Solaris 11.3 SRU 34. Uploads to Nextcloud (which internally uses SabreDAV) initiated by macOS Finder's builtin WebDAV client produce empty files in Nextcloud 13.0.5 storage. When changing from "mod_proxy_fcgi" and PHP-FPM back to the "libphp" module, the problem is gone, but I can only run Apache in prefork MPM then due to multi-threading-related issues in PHP. The main problem is that the user on the WebDAV client site doesn't necessarily get noticed about a problem at all. The uploaded files are just empty which is a major failure in my opinion, because data integrity is not guaranteed. Only when uploading larger files (haven't found the size limit yet), the user receivers an unspecified "WebDAV error -36". After analyzing this further, I am very sure that it is caused by the chunked encoding WebDAV PUT requests which are used by Apple's Finder. Some other WebDAV clients don't show the problem with the same server setup because they use other methods. According to the discussion of the PHP developers [1], this is a behavior against the specification.
