Edit report at https://bugs.php.net/bug.php?id=70361&edit=1 ID: 70361 Comment by: divinity76 at gmail dot com Reported by: me at kelunik dot com Summary: HTTP stream wrapper doesn't close keep-alive connections Status: Closed Type: Bug Package: Streams related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: note that "fixing" this may actually break code that communicate with dodgy http servers sending the wrong content-length header. the original code will read all bytes until the connection closes, completely disregarding content-length (which, with keep-alive connections, can have huge performance penalties), thus still working if the content-header is incorrect :p not saying this isn't a good thing, just that it IS a edge-case backward-incompatible change Previous Comments: ------------------------------------------------------------------------ [2015-09-15 12:13:41] ab@php.net Automatic comment on behalf of me@kelunik.com Revision: http://git.php.net/?p=php-src.git;a=commit;h=4b1dff6f438f84f7694df701b68744edbdd86153 Log: Fix #70361: HTTP stream wrapper doesn't close keep-alive connections ------------------------------------------------------------------------ [2015-09-04 14:36:01] bwoebi@php.net Automatic comment on behalf of me@kelunik.com Revision: http://git.php.net/?p=php-src.git;a=commit;h=4b1dff6f438f84f7694df701b68744edbdd86153 Log: Fix #70361: HTTP stream wrapper doesn't close keep-alive connections ------------------------------------------------------------------------ [2015-09-04 14:32:53] bwoebi@php.net Automatic comment on behalf of me@kelunik.com Revision: http://git.php.net/?p=php-src.git;a=commit;h=4b1dff6f438f84f7694df701b68744edbdd86153 Log: Fix #70361: HTTP stream wrapper doesn't close keep-alive connections ------------------------------------------------------------------------ [2015-08-25 22:05:59] me at kelunik dot com Patch is outdated, PR contains test fixes and NEWS entry. ------------------------------------------------------------------------ [2015-08-25 18:04:48] me at kelunik dot com Description: ------------ Downloading a file with file_get_contents("http://example.com/example.json"); defaults to using HTTP/1.0. RFC compliant servers should respond with a HTTP/1.1 in such a case if they support HTTP/1.1. Some servers initiate a keep-alive connection in that case, resulting a client hang, because PHP waits until the connection is closed instead of relying on the Content-Length header. This behavior should be fixed in two ways: (1) Always send "Connection: close" – even for HTTP/1.0 requests – and (2) use Content-Length to determine the end of a response and close the connection then. My attached patch only fixes the first point.
