FreeBSD's sendmsg() requires msg_name in msghdr structure
to be NULL if not used, setting msg_namelen to 0 isn't enough.

122        * Remove unused parameter to item_size_ok()
123
124        * Use a single printf() in usage()
125
126        * Add a failing test for conforming with maximum connections.
127
1282007-03-17
129        * crash fix from Thomas van Gulick <thomas@partyflock.nl> in
130          conn_shrink(), passing &ptr, instead of ptr to realloc().
131
1322007-03-05  Paul Lindner  <lindner@inuus.com>
133        * Fix a number of places where (s)printf calls were using unsigned
134          or signed formats that did not match their arguments.
135
136        * Add support for stdbool.h and stdint.h to use the bool and
137          uint8_t types.
138
139        * Major refactoring - move API calls for assoc/items/slabs to
140          their own individual header files.  Add apropriate const and
141          static declarations as appropriate.
142       
143        * Avoid type-punning.  Do a more efficient realloc inside the
144          conn_shrink routine.
145
146        * Fix overflow bug where uninitialized access to slabclass caused
147          size-0 mallocs during slab preallocation.
148
149        * Use EXIT_SUCCESS/EXIT_FAILURE constants.
150
151        * Convert some sprintf calls to snprintf to protect against
152          buffer overflows.
153
154        * Explicitly compare against NULL or zero in many places.
155
1562007-03-05
157        * Steven Grimm <sgrimm@facebook.com>: Per-object-type stats collection
158          support. Specify the object type delimiter with the -D command line
159          option. Turn stats gathering on and off with "stats detail on" and
160          "stats detail off". Dump the per-object-type details with
161          "stats detail dump".
162
1632007-03-01
164        * Steven Grimm <sgrimm@facebook.com>: Fix an off-by-one error in the
165          multithreaded version's message passing code.
166
1672006-12-23
168        * fix expirations of items set with absolute expiration times in
169          the past, before the server's start time.  bug was introduced in
170          1.2.0 with rel_time_t.  Thanks to Adam Dixon
171          <adamtdixon@gmail.com> for the bug report and test case!
172
1732006-11-26
174        * Steven Grimm <sgrimm@facebook.com>: Performance improvements:
175         
176          Dynamic sizing of hashtable to reduce collisions on very large
177          caches and conserve memory on small caches.
178
179          Only reposition items in the LRU queue once a minute, to reduce
180          overhead of accessing extremely frequently-used items.
181
182          Stop listening for new connections until an existing one closes
183          if we run out of available file descriptors.
184
185          Command parser refactoring: Add a single-pass tokenizer to cut
186          down on string scanning.  Split the command processing into
187          separate functions for easier profiling and better readability.
188          Pass key lengths along with the keys in all API functions that
189          need keys, to avoid needing to call strlen() repeatedly.
190
1912006-11-25
192        * Steve Peters <steve@fisharerojo.org>: OpenBSD has a malloc.h,
193        but warns to use stdlib.h instead
194
1952006-11-22
196        * Steven Grimm <sgrimm@facebook.com>: Add support for multithreaded
197          execution. Run configure with "--enable-threads" to enable. See
198          doc/threads.txt for details.
199
2002006-11-13
201        * Iain Wade <iwade@optusnet.com.au>: Fix for UDP responses on non-"get"
202         commands.
203
2042006-10-15
205        * Steven Grimm <sgrimm@facebook.com>: Dynamic sizing of hashtable to
206          reduce collisions on very large caches and conserve memory on
207          small caches.
208
2092006-10-13
210        * Steven Grimm <sgrimm@facebook.com>: New faster hash function.
211
2122006-09-20
213
214        * don't listen on UDP by default; more clear message when UDP port in use
215
2162006-09-09
217        * release 1.2.0 (along with 1.1.13, which is the more tested branch)
218
219        nobody has run 1.2.0 in production, to my knowledge.  facebook has run
220        their pre-merge-with-trunk version, but bugs were discovered (and fixed)
221        after the merge.  there might be more.  you've been warned.  :)
222
2232006-09-04
224        * improved autoconf libevent detection, from the Tor project.
225
2262006-09-03
227        * test suite and lot of expiration, delete, flush_all, etc corner
228          case bugs fixed (Brad Fitzpatrick)
229
2302006-09-02
231        * Nathan Neulinger <nneul@umr.edu>: fix breakage in expiration code
232          causing expiration times to not be processed correctly.
233
2342006-08-21
235        * Nathan Neulinger <nneul@umr.edu>: fix incompatabilities with
236          unix domain socket support and the UDP code and clean up stale
237          sockets
238
2392006-08-20
240        * Nathan Neulinger <nneul@umr.edu>: unix domain socket support
241
2422006-05-03
243        * Steven Grimm <sgrimm@facebook.com>:  big bunch of changes:
244          big CPU reduction work, UDP-based interface, increased memory
245          efficiency.  (intertwined patch, committed all together)
246          <http://lists.danga.com/pipermail/memcached/2006-May/002164.html>
247          or see svn commit logs
248
2492006-04-30
250        * River Tarnell:  autoconf work for Solaris 10.  Brad:
251        merge and verify it works on Nexenta.
252
2532006-03-04
254        * avva: bucket/generation patch (old, but Brad's just finally
255        committing it)
256
2572006-01-01
258        * Brad Fitzpatrick <brad@danga.com>:  allocate 1 slab per class
259        on start-up, to avoid confusing users with out-of-memory errors
260        later.  this is 18 MB of allocation on start, unless max memory
261        allowed with -m is lower, in which case only the smaller slab
262        classes are allocated.
263
2642005-08-09
265        * Elizabeth Mattijsen <liz@dijkmat.nl>: needed a way to flush all
266        memcached backend servers, but not at exactly the same time (to
267        reduce load peaks), I've added some simple functionality to the
268        memcached protocol in the "flush_all" command that allows you to
269        specify a time at which the flush will actually occur (instead of
270        always at the moment the "flush_all" command is received).
271
2722005-05-25
273        * patch from Peter van Dijk <peter@nextgear.nl> to make
274          stderr unbuffered, for running under daemontools
275
2762005-04-04
277        * patch from Don MacAskill <don@smugmug.com> 'flush_all' doesn't
278        seem to work properly.  Basically, if you try to add a key which
279        is present, but expired, the store fails but the old key is no
280        longer expired.
281
282        * release 1.1.12
283
2842005-01-14
285        * Date: Thu, 18 Nov 2004 15:25:59 -0600
286          From: David Phillips <electrum@gmail.com>
287        Here is a patch to configure.ac and Makefile.am to put the man page in
288        the correct location.  Trying to install the man page from a
289        subdirectory results in the subdirectory being used in the install
290        path (it tries to install to doc/memcached.1).  This is the correct
291        thing to  do:
292
293        - create a Makefile.am in the doc directory that installs the man page
294          with man_MANS
295        - modify Makefile.am in the base directory to reference the doc
296          directory using SUBDIRS
297        - modify the AC_CONFIG_FILES macro in configure.ac to output the
298          Makefile in doc
299
300       
3012005-01-14
302        * pidfile saving support from Lisa Seelye <lisa@gentoo.org>, sent
303          Jan 13, 2005
304
3052005-01-14
306        * don't delete libevent events that haven't been added (the deltimer)
307          patch from Ted Schundler <tschundler@gmail.com>
308
3092004-12-10
310        * document -M and -r in manpage (Doug Porter <dsp@dsp.name>)
311
3122004-07-22
313        * fix buffer overflow in items.c with 250 byte keys along with
314          other info on the same line going into a 256 byte char[].
315          thanks to Andrei Nigmatulin <anight@monamour.ru>
316       
3172004-06-15
318        * immediate deletes weren't being unlinked a few seconds,
319          preventing "add" commands to the same key in that time period.
320          thanks to Michael Alan Dorman <mdorman@debian.org> for the
321          bug report and demo script.
322       
3232004-04-30
324        * released 1.1.11
325
3262004-04-24
327        * Avva: Add a new command line option: -r , to maximize core file
328        limit.
329
3302004-03-31
331        * Avva: Use getrlimit and setrlimit to set limits for number of
332        simultaneously open file descriptors. Get the current limits and
333        try to raise them if they're not enough for the specified (or the
334        default) setting of max connections.
335       
3362004-02-24
337        * Adds a '-M' flag to turn off tossing items from the cache.
338          (Jason Titus <jtitus@postini.com>)
339
3402004-02-19 (Evan)
341        * Install manpage on "make install", etc.
342
3432003-12-30 (Brad)
344        * remove static build stuff.  interferes with PAM setuid stuff
345          and was only included as a possible fix with the old memory
346          allocator.  really shouldn't make a difference.
347        * add Jay Bonci's Debian scripts and manpage
348        * release version 1.1.10
349
3502003-12-01 (Avva)
351        * New command: flush_all, causes all existing items to
352          be invalidated immediately (without deleting them from
353          memory, merely causing memcached to no longer return them).
3542003-10-23
355        * Shift init code around to fix daemon mode on FreeBSD,
356        * and drop root only after creating the server socket (to
357        * allow the use of privileged ports)
358        * version 1.1.10pre
359
3602003-10-09
361        * BSD compile fixes from Ryan T. Dean
362        * version 1.1.9
363       
3642003-09-29
365        * ignore SIGPIPE at start instead of crashing in rare cases it
366          comes up.  no other code had to be modified, since everything
367          else is already dead-connection-aware.  (avva)
368       
3692003-09-09 (Avva, Lisa Marie Seelye <lisa@gentoo.org>)
370        * setuid support
371       
3722003-09-05 (Avva)
373        * accept all new connections in the same event (so we work with ET epoll)
374        * mark all items as clsid=0 after slab page reassignment to please future
375          asserts (on the road to making slab page reassignment work fully)
376
3772003-08-12 (Brad Fitzpatrick)
378        * use TCP_CORK on Linux or TCP_PUSH on BSD
379        * only use TCP_NODELAY when we don't have alternatives
380       
3812003-08-10
382        * disable Nagel's Algorithm (TCP_NODELAY) for better performance (avva)
383
3842003-08-10
385        * support multiple levels of verbosity (-vv)
386
3872003-08-10  (Evan Martin)
388        * Makefile.am: debug, optimization, and static flags are controlled
389          by the configure script.
390        * configure.ac:
391          - allow specifying libevent directory with --with-libevent=DIR
392          - check for malloc.h (unavailable on BSDs)
393          - check for socklen_t (unavailable on OSX)
394        * assoc.c, items.c, slabs.c:  Remove some unused headers.
395        * memcached.c:  allow for nonexistence of malloc.h; #define a POSIX
396          macro to import mlockall flags.
397
3982003-07-29
399        * version 1.1.7
400        * big bug fix: item exptime 0 meant expire immediately, not never
401        * version 1.1.8
402
4032003-07-22
404        * make 'delete' take second arg, of time to refuse new add/replace
405        * set/add/replace/delete can all take abs or delta time (delta can't
406          be larger than a month)
407
