to me that it may cause a problem if there agent-check is | |||
configured and there is some kind of error making a connection for it. | |||

Subject: [PATCH] BUG/MEDIUM: http: fetch "base" is not compatible with | |||
set-header | |||
The sample fetch function "base" makes use of the trash which is also | |||
used by set-header/add-header etc... everything which builds a formated | |||
line. So we end up with some junk in the header if base is in use. Let's | |||
fix this as all other fetches by using a trash chunk instead. | |||
This bug was reported by Baptiste Assmann, and also affects 1.5. | |||

For some browsers (firefox), an expired OCSP Response causes unwanted behavior. | |||
Haproxy stops serving OCSP response if nextupdate date minus | |||
the supported time skew (#define OCSP_MAX_RESPONSE_TIME_SKEW) is | |||
in the past. | |||

Subject: [PATCH 5/5] BUG/MAJOR: session: revert all the crappy client-side | |||
timeout changes | |||
This is the 3rd regression caused by the changes below. The latest to | |||
date was reported by Finn Arne Gangstad. If a server responds with no | |||
content-length and the client's FIN is never received, either we leak | |||
the client-side FD or we spin at 100% CPU if timeout client-fin is set. | |||
Enough is enough. The amount of tricks needed to cover these side-effects | |||
starts to look like used toilet paper stacked over a chocolate cake. I | |||
don't want to eat that cake anymore! | |||
All this to avoid reporting a server-side timeout when a client stops | |||
uploading data and haproxy expires faster than the server... A lot of | |||
"ifs" resulting in a technically valid log that doesn't always please | |||
users, and whose alternative causes that many issues for all others | |||
users. | |||
So let's revert this crap merged since 1.5-dev25 : | |||
Revert "CLEANUP: http: don't clear CF_READ_NOEXP twice" | |||
This reverts commit 1592d1e72a4a2d25a554c299ae95a3e6cad80bf1. | |||
Revert "BUG/MEDIUM: http: clear CF_READ_NOEXP when preparing a new transaction" | |||
This reverts commit 77d29029af1c44216b190dd7442964b9d8f45257. | |||
Revert "BUG/MEDIUM: session: don't clear CF_READ_NOEXP if analysers are not called" | |||
This reverts commit 0943757a2144761c60e416b5ed07baa76934f5a4. | |||
Revert "BUG/MEDIUM: http: disable server-side expiration until client has sent the body" | |||
This reverts commit 3bed5e9337fd6eeab0f0006ebefcbe98ee5c4f9f. | |||
Revert "BUG/MEDIUM: http: correctly report request body timeouts" | |||
This reverts commit b9edf8fbecc9d1b5c82794735adcc367a80a4ae2. | |||
Revert "BUG/MEDIUM: http/session: disable client-side expiration only after body" | |||
This reverts commit b1982e27aaff2a92a389a9f1bc847e3bb8fdb4f2. | |||
If a cleaner AND SAFER way to do something equivalent in 1.6-dev, we *might* | |||
consider backporting it to 1.5, but given the vicious bugs that have surfaced | |||
since, I doubt it will happen any time soon. | |||
Fortunately, that crap never made it into 1.4 so no backport is needed. | |||

Subject: [PATCH 6/6] BUG/MINOR: logs: properly initialize and count log | |||
sockets | |||
Commit 81ae195 ("[MEDIUM] add support for logging via a UNIX socket") | |||
merged in 1.3.14 introduced a few minor issues with log sockets. All | |||
of them happen only when a failure is encountered when trying to set | |||
up the logging socket (eg: socket family is not available or is | |||
temporarily short in resources). | |||
The first socket which experiences an error causes the socket setup | |||
loop to abort, possibly preventing any log from being sent if it was | |||
the first logger. The second issue is that if this socket finally | |||
succeeds after a second attempt, errors are reported for the wrong | |||
logger (eg: logger #1 failed instead of #2). The last point is that | |||
we now have multiple loggers, and it's a waste of time to walk over | |||
their list for every log while they're almost always properly set up. | |||
So in order to fix all this, let's merge the two lists. If a logger | |||
experiences an error, it simply sends an alert and skips to the next | |||
one. That way they don't prevent messages from being sent and are | |||
all properly accounted for. | |||
