+Subject: BUG/MINOR: config: use a copy of the file name in proxy configurations
+
+Each proxy contains a reference to the original config file and line
+number where it was declared. The pointer used is just a reference to
+the one passed to the function instead of being duplicated. The effect
+is that it is not valid anymore at the end of the parsing and that all
+proxies will be enumerated as coming from the same file on some late
+configuration errors. This may happen for exmaple when reporting SSL
+certificate issues.
+
+By copying using strdup(), we avoid this issue.
+
+1.4 has the same issue, though no report of the proxy file name is done
+out of the config section. Anyway a backport is recommended to ease
+post-mortem analysis.

+Subject: BUG/MINOR: epoll: correctly disable FD polling in fd_rem()
+
+When calling fd_rem(), the polling was not correctly disabled because the
+->prev state was set to zero instead of the previous value. fd_rem() is
+very rarely used, only just before closing a socket.
+
+The effect is that upon an error reported at the connection level, if the
+task assigned to the connection was too slow to be woken up because of too
+many other tasks in the run queue, the FD was still not disabled and caused
+the connection handler to be called again with the same event until the task
+was finally executed to close the fd.
+
+This issue only affects the epoll poller, not the sepoll variant nor any of
+the other ones.
+
+It was already present in 1.4 and even 1.3 with the same almost unnoticeable
+effects. The bug can in fact only be discovered during development where it
+emphasizes other bugs.
+
+It should be backported anyway.

+Subject: CONTRIB: halog: sort URLs by avg bytes_read or total bytes_read
+
+The patch attached to this mail brings ability to sort URLs by
+averaged bytes read and total bytes read in HALog tool.
+In most cases, bytes read is also the object size.
+The purpose of this patch is to know which URL consume the most
+bandwith, in average or in total.
+It may be interesting as well to know the standard deviation (ecart
+type in french) for some counters (like bytes_read).
+
+The results:

+Subject: BUG/MEDIUM: http: set DONTWAIT on data when switching to tunnel mode
+
+Jaroslaw Bojar diagnosed an issue when haproxy switches to tunnel mode
+after a transfer. The response data are sent with the MSG_MORE flag,
+causing them to be needlessly queued in the kernel. In order to fix this,
+we set the CF_NEVER_WAIT flag on the channels when switching to tunnel
+mode.
+
+One issue remained with client-side keep-alive : if the response is sent
+before the end of the request, it suffers the same issue for the same
+reason. This is easily addressed by setting the CF_SEND_DONTWAIT flag
+on the channel when the response has been parsed and we're waiting for
+the other side.
+
+The same issue is present in 1.4 so the fix must be backported.

+Subject: BUG: fix garbage data when http-send-name-header replaces an existing header
+
+This patch is an attempt to prevent sending garbage data when
+http-send-name-header replaced existing headers in the request.
+
+http-send-name-header is applied late in the request processing. The buffer is
+already ready to be sent to the backend server. When headers are removed, the
+data length is not modified, resulting in sending more data than required. By
+reducing the data length to send after removing them, this should fix the
+issue.
+
+This patch doesn't need to be ported to haproxy-1.5, which already readjust the
+amount of data to be forwarded.
+
+This issue was reported by Michael Seiferle at BaseX, who also tested and
+confirmed the fix.

+
+[ note: this backport is not absolutely required for 1.4 but it eases
+ further backports ]
+
+Using "halog -c" is still something quite common to perform on logs,
+but unfortunately since the recent added controls, it was sensibly
+slowed down due to the parsing of the accept date field.
+
+Now we use a specific loop for the case where nothing is needed from
+the input, and this sped up the line counting by 2.5x. A 2.4 GHz Xeon
+now counts lines at a rate of 2 GB of logs per second.

+Subject: BUG: halog: fix broken output limitation
+
+Commit 667c905f introduced parameter -m to halog which limits the size
+of the output. Unfortunately it is completely broken in that it doesn't
+check that the limit was previously set or not, and also prevents a
+simple counting operation from returning anything if a limit is not set.
+
+Note that the -gt and -pct outputs behave differently in face of this
+limit, since they count the valid output lines BEFORE actually producing
+the data, so the limit really applies to valid input lines.

+Subject: MEDIUM: checks: avoid accumulating TIME_WAITs during checks
+
+Some checks which do not induce a close from the server accumulate
+local TIME_WAIT sockets because they're cleanly shut down. Typically
+TCP probes cause this. This is very problematic when there are many
+servers, when the checks are fast or when local source ports are rare.
+
+So now we'll disable lingering on the socket instead of sending a
+shutdown. Before doing this we try to drain any possibly pending data.
+That way we avoid sending an RST when the server has closed first.
+
+This change means that some servers will see more RSTs, but this is
+needed to avoid local source port starvation.

+Subject: BUG/MAJOR: cli: show sess <id> may randomly corrupt the back-ref list
+
+show sess <id> puts a backref into the session it's dumping. If the output
+is interrupted, the backref cannot always be removed because it's only done
+in the I/O handler. This can randomly corrupt the backref list when the
+session closes, because it passes the pointer to the next session which
+itself might be watched.
+
+The case is hard to reproduce (hundreds of attempts) but monitoring systems
+might encounter it frequently.
+
+Thus we have to add a release handler which does the cleanup even when the
+I/O handler is not called.
+
+This issue should also be present in 1.4 so the patch should be backported.
+(cherry picked from commit 5f9a8779b3d4fb324dacc1daacfb478bd12963d1)
+
+NOTE: In 1.4 there is no release function so we have to hard-code the
+release in session.c when the condition is encountered.

+Subject: BUG/MINOR: http: don't report client aborts as server errors
+
+If a client aborts with an abortonclose flag, the close is forwarded
+to the server and when server response is processed, the analyser thinks
+it's the server who has closed first, and logs flags "SD" or "SH" and
+counts a server error. In order to avoid this, we now first detect that
+the client has closed and log a client abort instead.
+
+This likely is the reason why many people have been observing a small rate
+of SD/SH flags without being able to find what the error was.
+
+This fix should probably be backported to 1.4.

+Subject: BUG/MEDIUM: tcp: process could theorically crash on lack of source ports
+
+When connect() fails with EAGAIN or EADDRINUSE, an error message is
+sent to logs and uses srv->id to indicate the server name (this is
+very old code). Since version 1.4, it is possible to have srv == NULL,
+so the message could cause a crash when connect() returns EAGAIN or
+EADDRINUSE. However in practice this does not happen because on lack
+of source ports, EADDRNOTAVAIL is returned instead, so this code is
+never called.
+
+This fix consists in not displaying the server name anymore, and in
+adding the test for EADDRNOTAVAIL.
+
+Also, the log level was lowered from LOG_EMERG to LOG_ERR in order
+not to spam all consoles when source ports are missing for a given
+target.
+
+This fix should be backported to 1.4.

+
+When a server responds prematurely to a POST request, haproxy used to
+cause the transfer to be aborted before the end. This is problematic
+because this causes the client to receive a TCP reset when it tries to
+push more data, generally preventing it from receiving the response
+which contain the reason for the premature reponse (eg: "entity too
+large" or an authentication request).
+
+From now on we take care of allowing the upload traffic to flow to the

+
+This bug has been present since 1.4 and the fix should probably be

+experience an average response time of 99.5 ms with a standard
+deviation of 2 ms.
+
+The reason for this inaccuracy is that when computing frequency
+counters, we use one part of the previous value proportional to the
+number of milliseconds remaining in the current second. But even the
+last millisecond still uses a part of the past value, which is wrong :
+since we have a 1ms resolution, the last millisecond must be dedicated
+only to filling the current second.
+
+So we slightly adjust the algorithm to use 999/1000 of the past value
+during the first millisecond, and 0/1000 of the past value during the
+last millisecond. We also slightly improve the computation by computing
+the remaining time instead of the current time in tv_update_date(), so
+that we don't have to negate the value in each frequency counter.
+
+Now with the fix, the connection rate measured by both the client and
+haproxy is a steady 1000/s, the average response time measured is 99.2ms
+and more importantly, the standard deviation has been divided by 3 to
+0.6 millisecond.
+
+This fix should also be backported to 1.4 which has the same issue.

+Subject: BUG/MINOR: http: don't process abortonclose when request was sent
+
+option abortonclose may cause a valid connection to be aborted just
+after the request has been sent. This is because we check for it
+during the session establishment sequence before checking for write
+activity. So if the abort and the connect complete at the same time,
+the abort is still considered. Let's check for an explicity partial
+write before aborting.
+
+This fix should be backported to 1.4 too.
