2        * Incorporate "cas" operation developed by Dustin
3          Sallings <dustin@spy.net> This change allows you
4          to do atomic changes to an existing key.
5
6        * Fix for stats.evictions not incrementing
7          when exptime == 0 items are kicked off the cache.
8          from Jean-Francois BUSTARRET <jfbustarret@wat.tv>.
9
10        * Fix for do_item_cachedump() which was returning
11          an incorrect timestamp.
12       
13        * Switch to unsigned 64-bit increment/decrement counters
14          from Evan Miller and Dustin Sallings.
15
16        * Add append command support written by Filipe Laborde.
17          Thread safe version plus prepend command from Maxim Dounin
18          <mdounin@mdounin.ru>
19
20        * The memcached-tool script can now display stats.  Patch
21          provided by Dan Christian <dchristian@google.com>
22
23        * Fix for Unix Domain sockets on FreeBSD
24          FreeBSD's sendmsg() requires msg_name in msghdr structure
25          to be NULL if not used, setting msg_namelen to 0 isn't enough.
26          Patch from Maxim Dounin <mdounin@mdounin.ru>
27
282007-08-21 Paul Lindner <lindner@inuus.com>

39
402007-07-08  Steven Grimm  <sgrimm@facebook.com>
41
42        * Item stats commands weren't thread-safe; wrap them with locks
43          when compiled in multithreaded mode.
44        * The "stats items" command now works again; it broke with the
45          introduction of the powers-of-N chunk size change.

1332007-03-05  Paul Lindner  <lindner@inuus.com>
134        * Fix a number of places where (s)printf calls were using unsigned
135          or signed formats that did not match their arguments.
136
137        * Add support for stdbool.h and stdint.h to use the bool and
138          uint8_t types.
139
140        * Major refactoring - move API calls for assoc/items/slabs to
141          their own individual header files.  Add apropriate const and
142          static declarations as appropriate.
143       
144        * Avoid type-punning.  Do a more efficient realloc inside the
145          conn_shrink routine.
146

154
155        * Explicitly compare against NULL or zero in many places.
156
1572007-03-05
158        * Steven Grimm <sgrimm@facebook.com>: Per-object-type stats collection
159          support. Specify the object type delimiter with the -D command line
160          option. Turn stats gathering on and off with "stats detail on" and
161          "stats detail off". Dump the per-object-type details with
162          "stats detail dump".
163
1642007-03-01
165        * Steven Grimm <sgrimm@facebook.com>: Fix an off-by-one error in the
166          multithreaded version's message passing code.
167
1682006-12-23
169        * fix expirations of items set with absolute expiration times in
170          the past, before the server's start time.  bug was introduced in
171          1.2.0 with rel_time_t.  Thanks to Adam Dixon
172          <adamtdixon@gmail.com> for the bug report and test case!
173
1742006-11-26
175        * Steven Grimm <sgrimm@facebook.com>: Performance improvements:
176         
177          Dynamic sizing of hashtable to reduce collisions on very large
178          caches and conserve memory on small caches.
179
180          Only reposition items in the LRU queue once a minute, to reduce
181          overhead of accessing extremely frequently-used items.
182
183          Stop listening for new connections until an existing one closes
184          if we run out of available file descriptors.
185
186          Command parser refactoring: Add a single-pass tokenizer to cut
187          down on string scanning.  Split the command processing into
188          separate functions for easier profiling and better readability.
189          Pass key lengths along with the keys in all API functions that
190          need keys, to avoid needing to call strlen() repeatedly.
191
1922006-11-25
193        * Steve Peters <steve@fisharerojo.org>: OpenBSD has a malloc.h,
194        but warns to use stdlib.h instead
195
1962006-11-22
197        * Steven Grimm <sgrimm@facebook.com>: Add support for multithreaded
198          execution. Run configure with "--enable-threads" to enable. See
199          doc/threads.txt for details.
200
2012006-11-13
202        * Iain Wade <iwade@optusnet.com.au>: Fix for UDP responses on non-"get"
203         commands.
204
2052006-10-15
206        * Steven Grimm <sgrimm@facebook.com>: Dynamic sizing of hashtable to
207          reduce collisions on very large caches and conserve memory on
208          small caches.
209
2102006-10-13
211        * Steven Grimm <sgrimm@facebook.com>: New faster hash function.
212
2132006-09-20
214
215        * don't listen on UDP by default; more clear message when UDP port in use
216
2172006-09-09
218        * release 1.2.0 (along with 1.1.13, which is the more tested branch)
219
220        nobody has run 1.2.0 in production, to my knowledge.  facebook has run
221        their pre-merge-with-trunk version, but bugs were discovered (and fixed)
222        after the merge.  there might be more.  you've been warned.  :)
223
2242006-09-04
225        * improved autoconf libevent detection, from the Tor project.
226
2272006-09-03
228        * test suite and lot of expiration, delete, flush_all, etc corner
229          case bugs fixed (Brad Fitzpatrick)
230
2312006-09-02
232        * Nathan Neulinger <nneul@umr.edu>: fix breakage in expiration code
233          causing expiration times to not be processed correctly.
234
2352006-08-21
236        * Nathan Neulinger <nneul@umr.edu>: fix incompatabilities with
237          unix domain socket support and the UDP code and clean up stale
238          sockets
239
2402006-08-20
241        * Nathan Neulinger <nneul@umr.edu>: unix domain socket support
242
2432006-05-03
244        * Steven Grimm <sgrimm@facebook.com>:  big bunch of changes:
245          big CPU reduction work, UDP-based interface, increased memory
246          efficiency.  (intertwined patch, committed all together)
247          <http://lists.danga.com/pipermail/memcached/2006-May/002164.html>
248          or see svn commit logs
249
2502006-04-30
251        * River Tarnell:  autoconf work for Solaris 10.  Brad:
252        merge and verify it works on Nexenta.
253
2542006-03-04
255        * avva: bucket/generation patch (old, but Brad's just finally
256        committing it)
257
2582006-01-01
259        * Brad Fitzpatrick <brad@danga.com>:  allocate 1 slab per class
260        on start-up, to avoid confusing users with out-of-memory errors
261        later.  this is 18 MB of allocation on start, unless max memory
262        allowed with -m is lower, in which case only the smaller slab
263        classes are allocated.
264
2652005-08-09
266        * Elizabeth Mattijsen <liz@dijkmat.nl>: needed a way to flush all
267        memcached backend servers, but not at exactly the same time (to
268        reduce load peaks), I've added some simple functionality to the
269        memcached protocol in the "flush_all" command that allows you to
270        specify a time at which the flush will actually occur (instead of
271        always at the moment the "flush_all" command is received).
272
2732005-05-25
274        * patch from Peter van Dijk <peter@nextgear.nl> to make
275          stderr unbuffered, for running under daemontools
276
2772005-04-04
278        * patch from Don MacAskill <don@smugmug.com> 'flush_all' doesn't
279        seem to work properly.  Basically, if you try to add a key which
280        is present, but expired, the store fails but the old key is no
281        longer expired.
282
283        * release 1.1.12
284
2852005-01-14
286        * Date: Thu, 18 Nov 2004 15:25:59 -0600
287          From: David Phillips <electrum@gmail.com>
288        Here is a patch to configure.ac and Makefile.am to put the man page in
289        the correct location.  Trying to install the man page from a
290        subdirectory results in the subdirectory being used in the install
291        path (it tries to install to doc/memcached.1).  This is the correct
292        thing to  do:
293
294        - create a Makefile.am in the doc directory that installs the man page
295          with man_MANS
296        - modify Makefile.am in the base directory to reference the doc
297          directory using SUBDIRS
298        - modify the AC_CONFIG_FILES macro in configure.ac to output the
299          Makefile in doc
300
301       
3022005-01-14
303        * pidfile saving support from Lisa Seelye <lisa@gentoo.org>, sent
304          Jan 13, 2005
305
3062005-01-14
307        * don't delete libevent events that haven't been added (the deltimer)
308          patch from Ted Schundler <tschundler@gmail.com>
309
3102004-12-10
311        * document -M and -r in manpage (Doug Porter <dsp@dsp.name>)
312
3132004-07-22
314        * fix buffer overflow in items.c with 250 byte keys along with
315          other info on the same line going into a 256 byte char[].
316          thanks to Andrei Nigmatulin <anight@monamour.ru>
317       
3182004-06-15
319        * immediate deletes weren't being unlinked a few seconds,
320          preventing "add" commands to the same key in that time period.
321          thanks to Michael Alan Dorman <mdorman@debian.org> for the
322          bug report and demo script.
323       
3242004-04-30
325        * released 1.1.11
326
3272004-04-24
328        * Avva: Add a new command line option: -r , to maximize core file
329        limit.
330
3312004-03-31
332        * Avva: Use getrlimit and setrlimit to set limits for number of
333        simultaneously open file descriptors. Get the current limits and
334        try to raise them if they're not enough for the specified (or the
335        default) setting of max connections.
336       
3372004-02-24
338        * Adds a '-M' flag to turn off tossing items from the cache.
339          (Jason Titus <jtitus@postini.com>)
340
3412004-02-19 (Evan)
342        * Install manpage on "make install", etc.
343
3442003-12-30 (Brad)
345        * remove static build stuff.  interferes with PAM setuid stuff
346          and was only included as a possible fix with the old memory
347          allocator.  really shouldn't make a difference.
348        * add Jay Bonci's Debian scripts and manpage
349        * release version 1.1.10
350
3512003-12-01 (Avva)
352        * New command: flush_all, causes all existing items to
353          be invalidated immediately (without deleting them from
354          memory, merely causing memcached to no longer return them).
3552003-10-23
356        * Shift init code around to fix daemon mode on FreeBSD,
357        * and drop root only after creating the server socket (to
358        * allow the use of privileged ports)
359        * version 1.1.10pre
360
3612003-10-09
362        * BSD compile fixes from Ryan T. Dean
363        * version 1.1.9
364       
3652003-09-29
366        * ignore SIGPIPE at start instead of crashing in rare cases it
367          comes up.  no other code had to be modified, since everything
368          else is already dead-connection-aware.  (avva)
369       
3702003-09-09 (Avva, Lisa Marie Seelye <lisa@gentoo.org>)
371        * setuid support
372       
3732003-09-05 (Avva)
374        * accept all new connections in the same event (so we work with ET epoll)
375        * mark all items as clsid=0 after slab page reassignment to please future
376          asserts (on the road to making slab page reassignment work fully)
377
3782003-08-12 (Brad Fitzpatrick)
379        * use TCP_CORK on Linux or TCP_PUSH on BSD
380        * only use TCP_NODELAY when we don't have alternatives
381       
3822003-08-10
383        * disable Nagel's Algorithm (TCP_NODELAY) for better performance (avva)
384
3852003-08-10
386        * support multiple levels of verbosity (-vv)
387
3882003-08-10  (Evan Martin)
389        * Makefile.am: debug, optimization, and static flags are controlled
390          by the configure script.
391        * configure.ac:
392          - allow specifying libevent directory with --with-libevent=DIR
393          - check for malloc.h (unavailable on BSDs)
394          - check for socklen_t (unavailable on OSX)
395        * assoc.c, items.c, slabs.c:  Remove some unused headers.
396        * memcached.c:  allow for nonexistence of malloc.h; #define a POSIX
397          macro to import mlockall flags.
398
3992003-07-29
400        * version 1.1.7
401        * big bug fix: item exptime 0 meant expire immediately, not never
402        * version 1.1.8
403
4042003-07-22
405        * make 'delete' take second arg, of time to refuse new add/replace
406        * set/add/replace/delete can all take abs or delta time (delta can't
407          be larger than a month)
408
