* Command tokenizer performance and cleanliness improvement.
Patch contributed by Paolo Borelli <paolo.borelli@gmail.com>.
2007-04-16 Paul Lindner <lindner@inuus.com>

2007-04-12 Paul Lindner <lindner@mirth.inuus.com>
* Allow changes to the verbosity level of the server with a new
"verbosity" command and some compiler cleanups.
Patch contributed by Paolo Borelli <paolo.borelli@gmail.com>.
2007-04-08 Paul Lindner <lindner@inuus.com>
* Add cleanup patch from "Tim Yardley" <liquid@haveheart.com> to
clean up source spacing issues, fix -Wall warnings, add some
null checks, adds asserts at the top of each function for any
use of conn *c without checking to see if c is NULL first.
* Also adjust clean-whitespace.pl to clean *.ac files. Add
script to test-suite to test for tabs.
2007-04-04 Paul Lindner <lindner@inuus.com>
* Add clarification of flush_all in the protocol docs
from Elizabeth Mattijsen <liz@dijkmat.nl>
2007-03-31 Paul Lindner <lindner@inuus.com>
* Add patch from Eli Bingham <eli@pandora.com> to
re-enable the -n switch to memcached.
2007-03-20 Paul Lindner <lindner@inuus.com>
* Add patch to collect eviction statistics from
Jean-Francois BUSTARRET <jfbustarret@wat.tv>.
* Updated docs, added new test cases for t/stats.t
2007-03-18 Paul Lindner <lindner@inuus.com>
* Add more test cases using larger buffer sizes up to and greater
than 1MB.
* Remove unused parameter to item_size_ok()
* Use a single printf() in usage()
* Add a failing test for conforming with maximum connections.
2007-03-17
* crash fix from Thomas van Gulick <thomas@partyflock.nl> in
conn_shrink(), passing &ptr, instead of ptr to realloc().
2007-03-05 Paul Lindner <lindner@inuus.com>
* Fix a number of places where (s)printf calls were using unsigned
or signed formats that did not match their arguments.
* Add support for stdbool.h and stdint.h to use the bool and
uint8_t types.
* Major refactoring - move API calls for assoc/items/slabs to
their own individual header files. Add apropriate const and
static declarations as appropriate.
* Avoid type-punning. Do a more efficient realloc inside the
conn_shrink routine.
* Fix overflow bug where uninitialized access to slabclass caused
size-0 mallocs during slab preallocation.
* Use EXIT_SUCCESS/EXIT_FAILURE constants.
* Convert some sprintf calls to snprintf to protect against
buffer overflows.
* Explicitly compare against NULL or zero in many places.
2007-03-05
* Steven Grimm <sgrimm@facebook.com>: Per-object-type stats collection
support. Specify the object type delimiter with the -D command line
option. Turn stats gathering on and off with "stats detail on" and
"stats detail off". Dump the per-object-type details with
"stats detail dump".
2007-03-01
* Steven Grimm <sgrimm@facebook.com>: Fix an off-by-one error in the
multithreaded version's message passing code.
2006-12-23
* fix expirations of items set with absolute expiration times in
the past, before the server's start time. bug was introduced in
1.2.0 with rel_time_t. Thanks to Adam Dixon
<adamtdixon@gmail.com> for the bug report and test case!
changes since 1.1.12:
2006-11-26
* Steven Grimm <sgrimm@facebook.com>: Performance improvements:
Dynamic sizing of hashtable to reduce collisions on very large
caches and conserve memory on small caches.
Only reposition items in the LRU queue once a minute, to reduce
overhead of accessing extremely frequently-used items.
Stop listening for new connections until an existing one closes
if we run out of available file descriptors.
Command parser refactoring: Add a single-pass tokenizer to cut
down on string scanning. Split the command processing into
separate functions for easier profiling and better readability.
Pass key lengths along with the keys in all API functions that
need keys, to avoid needing to call strlen() repeatedly.
2006-11-13
* Iain Wade <iwade@optusnet.com.au>: Fix for UDP responses on
non-"get" commands.
2006-10-13
* Steven Grimm <sgrimm@facebook.com>: New faster hash function.
2006-09-20
* don't listen on UDP by default; more clear message when UDP port
in use
2006-09-09
* release 1.2.0 (along with 1.1.13, which is the more tested branch)
2006-09-02
* Nathan Neulinger <nneul@umr.edu>: fix breakage in expiration code
causing expiration times to not be processed correctly.
2006-08-21
* Nathan Neulinger <nneul@umr.edu>: fix incompatabilities with
unix domain socket support and the UDP code and clean up stale
sockets
2006-08-20
* Nathan Neulinger <nneul@umr.edu>: unix domain socket support
2006-05-03
* Steven Grimm <sgrimm@facebook.com>: big bunch of changes:
big CPU reduction work, UDP-based interface, increased memory
efficiency. (intertwined patch, committed all together)

* Elizabeth Mattijsen <liz@dijkmat.nl>: needed a way to flush all
memcached backend servers, but not at exactly the same time (to
reduce load peaks), I've added some simple functionality to the
memcached protocol in the "flush_all" command that allows you to
specify a time at which the flush will actually occur (instead of
always at the moment the "flush_all" command is received).
2005-05-25
* patch from Peter van Dijk <peter@nextgear.nl> to make
stderr unbuffered, for running under daemontools
changes since 1.1.11:
2005-04-04
* patch from Don MacAskill <don@smugmug.com> 'flush_all' doesn't
seem to work properly. Basically, if you try to add a key which
is present, but expired, the store fails but the old key is no
longer expired.

From: David Phillips <electrum@gmail.com>
Here is a patch to configure.ac and Makefile.am to put the man page in
the correct location. Trying to install the man page from a
subdirectory results in the subdirectory being used in the install
path (it tries to install to doc/memcached.1). This is the correct
thing to do:
- create a Makefile.am in the doc directory that installs the man page
with man_MANS
- modify Makefile.am in the base directory to reference the doc
directory using SUBDIRS
- modify the AC_CONFIG_FILES macro in configure.ac to output the
Makefile in doc

* pidfile saving support from Lisa Seelye <lisa@gentoo.org>, sent
Jan 13, 2005
2005-01-14
* don't delete libevent events that haven't been added (the deltimer)
patch from Ted Schundler <tschundler@gmail.com>
2004-12-10
* document -M and -r in manpage (Doug Porter <dsp@dsp.name>)
2004-07-22
* fix buffer overflow in items.c with 250 byte keys along with
other info on the same line going into a 256 byte char[].
thanks to Andrei Nigmatulin <anight@monamour.ru>
2004-06-15
* immediate deletes weren't being unlinked a few seconds,
preventing "add" commands to the same key in that time period.
thanks to Michael Alan Dorman <mdorman@debian.org> for the
bug report and demo script.
memcached is a high-performance, distributed memory object caching
system, generic in nature, but intended for use in speeding up dynamic
web applications by alleviating database load.
