There was a problem hiding this comment.
While merging this up into 7.4, I found that we have 41c4816 there, which should have much the same effect -- the main difference I see is that it does not close and null the stream. The EOF branch below also doesn't do this. I'm wondering if it's necessary?

I did this to be coherent with lines 851 & 852 (
php-src/ext/standard/http_fopen_wrapper.c
Line 851 in 86e6cff
Removing both lines doesn't work because the stream is not technically EOF, so it still goes through the second call, thus applying 2 times the timeout.
Only php_stream_close(stream) -> seg fault
Only stream = null -> seems to work

Sorry for the delay, I forgot about this. Now merged as e691a98 into 7.2+. Thanks! |

Currently, if getting the response headers fails, we are still trying to read past them to get the content. Is that logical? 🤔
That's the cause of the fixed bug : the current behavior makes 2 call to
php_stream_get_line, thus "applying" 2 times the timeout. I guess that in the particular described setup, the end of stream is not detected. However, the timeout being applied 2 times is not coherent at all.I just moved the
/* read past HTTP headers */code block so it is executed only if getting the headers was successful. We can also fix it by forcing$stream->eof = 1;when the first call fails but I guess that's dirtier.I know close to nothing about C and PHP source code but at least the test can be used if it can be fixed in a better way 😄
