Before it was possible to resize the buffers using global.tune.bufsize, the trash has always been the size of a buffer by design. Unfortunately, the recent buffer sizing at runtime forgot to adjust the trash, resulting in it being too short for content rewriting if buffers were enlarged from the default value. The bug was encountered in 1.4 so the fix must be backported there.

Subject: Re: [PATCH] Flush buffers also where there are exactly 0 bytes left
|

I'm also attaching a debug patch that helps to trigger this bug.

|
|
Without the fix:
|
|
# echo -ne "GET /haproxy?stats;csv;norefresh HTTP/1.0\r\n\r\n"|nc 127.0.0.1=
|
|
801|wc -c
