Edit report at https://bugs.php.net/bug.php?id=51191&edit=1 ID: 51191 Comment by: tim dot siebels at iserv dot eu Reported by: evert at rooftopsolutions dot nl Summary: Request body is 0-size when chunked requests are used Status: Open Type: Feature/Change Request Package: CGI/CLI related Operating System: * PHP Version: 5.3.1 Block user comment: N Private report: N New Comment: Thanks! As a result, I raised these concerns here: https://trac.nginx.org/nginx/ticket/2287 Previous Comments: ------------------------------------------------------------------------ [2021-11-27 19:44:02] bukka@php.net I think FastCGI spec is quite clear about using CGI/1.1 in responder - see http://www.mit.edu/~yandros/doc/specs/fcgi-spec.html#S6.2 . It means that CONTENT_LENGTH is required by spec because it is required by CGI/1.1. Thus I don't think this is a bug and to change that, we would need to change a spec. ------------------------------------------------------------------------ [2021-09-23 11:40:33] cmb@php.net See <https://bugs.php.net/bug.php?id=60826#1582825832>. However, the FastCGI specs are less clear on that, and I tend to agree that it makes sense to support chunked requests. ------------------------------------------------------------------------ [2021-09-23 11:01:48] tim dot siebels at iserv dot eu The following pull request has been associated: Patch Name: Fixed reading in streamed body using fastcgi On GitHub: https://github.com/php/php-src/pull/7509 Patch: https://github.com/php/php-src/pull/7509.patch ------------------------------------------------------------------------ [2021-09-15 07:11:36] tim dot siebels at iserv dot eu We are encountering this issue when disabling fastcgi_request_buffering in nginx. Apparently, others are too [0,1]. The older bug [1] led to apache "fixing" this issue by buffering all chunked requests. I've opened a thread on the nginx mailinglist [2] regarding this. The assessment there is, that fastcgi is a inherently chunked protocol and thus php should not depend on the CONTENT_LENGTH variable, and rather read out all the fastcgi records to get the body. How do you feel about this? Do you agree that this should be fixed in php?

Nginx and Lighttpd don't seem to support this feature at all, and simply return 411 Length Required, but with Apache the request goes through but PHP ends up with an empty request body. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
