Hi all, Krzysztof Oledzki managed to make dev7 reliably crash. After investigation, it appeared that one of the latest keep-alive bugs I had fixed was not complete as the same code was present in another function.
In practice, 1.4-dev5, -dev6 and -dev7 are affected by the same bug and may randomly crash in http-server-close mode (or corrupt part of their memory) when users are running at low speed with pipelined requests and that the server is very fast, and many headers are added or rewritten in the response. So I'm releasing 1.4-dev8 with that nasty bug fixed, so that people don't take useless risks and we can make a difference between that bug and any possibly new one in bug reports. A few other minor issues were fixed (eg: don't forward invalid pending response data when closing a keep-alive connection). Cyril Bonté also did a nice review of config options in the doc versus the parser in order to fix both to make them agree. Last, some of you may be aware that most browsers and proxies use the non-standard HTTP header Proxy-Connection instead of Connection when talking on proxied connections. This one requires special handling as such non-conform HTTP agents simply ignore the Connection header which is still the only one defined by the spec. So I have added an option for frontends for those who want to deploy haproxy in front of a proxy farm with keep-alive. This option allows haproxy to automatically detect proxied connections (URL does not start by '/' nor '*') and switch to Proxy-Connection instead of Connection. I don't recommend enabling that by default when not needed. Well, hopefully this time 1.4-dev8 will be reliable... It's available at the usual place : http://haproxy.1wt.eu/download/1.4/src/ http://haproxy.1wt.eu/download/1.4/src/haproxy-1.4-dev8.tar.gz http://haproxy.1wt.eu/download/1.4/src/CHANGELOG http://haproxy.1wt.eu/download/1.4/doc/configuration.txt Please report any regression or issue you may observe. And keep in mind that it MUST NOT crash, never ever. If it ever does, please complain here loudly with maximum information. Thanks, Willy
