362007-10-15  Paul Lindner  <[email protected]>
37
38	* Patch from David Bremner <[email protected]> that implements
39	  a new option "-a" which takes an octal permission mask
40	  (like chmod) sets the permissions on the unix domain socket
41	  (specified by "-s").
42
432007-10-03 Paul Lindner <[email protected]>
44	* Incorporate "cas" operation developed by Dustin
45	  Sallings <[email protected]> This change allows you

64
65	* Fix for Unix Domain sockets on FreeBSD

132          Patch contributed by Paolo Borelli <[email protected]>.
133
1342007-04-08  Paul Lindner  <[email protected]>
135
136	* Add cleanup patch from "Tim Yardley" <[email protected]> to

139	  use of conn *c without checking to see if c is NULL first.
140
141        * Also adjust clean-whitespace.pl to clean *.ac files.  Add

170
1712007-03-17
172	* crash fix from Thomas van Gulick <[email protected]> in
173	  conn_shrink(), passing &ptr, instead of ptr to realloc().
174
1752007-03-05  Paul Lindner  <[email protected]>
176	* Fix a number of places where (s)printf calls were using unsigned
177	  or signed formats that did not match their arguments.
178
179	* Add support for stdbool.h and stdint.h to use the bool and
180	  uint8_t types.
181
182	* Major refactoring - move API calls for assoc/items/slabs to
183	  their own individual header files.  Add apropriate const and
184	  static declarations as appropriate.
185
186	* Avoid type-punning.  Do a more efficient realloc inside the
187	  conn_shrink routine.
188
189        * Fix overflow bug where uninitialized access to slabclass caused
190	  size-0 mallocs during slab preallocation.
191
192	* Use EXIT_SUCCESS/EXIT_FAILURE constants.
193
194	* Convert some sprintf calls to snprintf to protect against
195	  buffer overflows.
196
197	* Explicitly compare against NULL or zero in many places.
198
1992007-03-05
200	* Steven Grimm <[email protected]>: Per-object-type stats collection
201	  support. Specify the object type delimiter with the -D command line
202	  option. Turn stats gathering on and off with "stats detail on" and
203	  "stats detail off". Dump the per-object-type details with
204	  "stats detail dump".
205
2062007-03-01
207	* Steven Grimm <[email protected]>: Fix an off-by-one error in the
208	  multithreaded version's message passing code.
209
2102006-12-23
211	* fix expirations of items set with absolute expiration times in
212	  the past, before the server's start time.  bug was introduced in
213	  1.2.0 with rel_time_t.  Thanks to Adam Dixon
214	  <[email protected]> for the bug report and test case!
215
2162006-11-26
217	* Steven Grimm <[email protected]>: Performance improvements:
218
219	  Dynamic sizing of hashtable to reduce collisions on very large
220	  caches and conserve memory on small caches.
221
222	  Only reposition items in the LRU queue once a minute, to reduce
223	  overhead of accessing extremely frequently-used items.
224
225	  Stop listening for new connections until an existing one closes
226	  if we run out of available file descriptors.
227
228	  Command parser refactoring: Add a single-pass tokenizer to cut
229	  down on string scanning.  Split the command processing into
230	  separate functions for easier profiling and better readability.
231	  Pass key lengths along with the keys in all API functions that
232	  need keys, to avoid needing to call strlen() repeatedly.
233
2342006-11-25
235	* Steve Peters <[email protected]>: OpenBSD has a malloc.h,
236	but warns to use stdlib.h instead
237
2382006-11-22
239	* Steven Grimm <[email protected]>: Add support for multithreaded
240	  execution. Run configure with "--enable-threads" to enable. See
241	  doc/threads.txt for details.
242
2432006-11-13
244	* Iain Wade <[email protected]>: Fix for UDP responses on non-"get"
245	 commands.
246
2472006-10-15
248	* Steven Grimm <[email protected]>: Dynamic sizing of hashtable to
249	  reduce collisions on very large caches and conserve memory on
250	  small caches.
251
2522006-10-13
253	* Steven Grimm <[email protected]>: New faster hash function.
254
2552006-09-20
256
257	* don't listen on UDP by default; more clear message when UDP port in use
258
2592006-09-09
260	* release 1.2.0 (along with 1.1.13, which is the more tested branch)
261
262	nobody has run 1.2.0 in production, to my knowledge.  facebook has run
263	their pre-merge-with-trunk version, but bugs were discovered (and fixed)
264	after the merge.  there might be more.  you've been warned.  :)
265
2662006-09-04
267	* improved autoconf libevent detection, from the Tor project.
268
2692006-09-03
270	* test suite and lot of expiration, delete, flush_all, etc corner
271	  case bugs fixed (Brad Fitzpatrick)
272
2732006-09-02
274	* Nathan Neulinger <[email protected]>: fix breakage in expiration code
275	  causing expiration times to not be processed correctly.
276
2772006-08-21
278	* Nathan Neulinger <[email protected]>: fix incompatabilities with
279	  unix domain socket support and the UDP code and clean up stale
280	  sockets
281
2822006-08-20
283	* Nathan Neulinger <[email protected]>: unix domain socket support
284
2852006-05-03
286	* Steven Grimm <[email protected]>:  big bunch of changes:
287	  big CPU reduction work, UDP-based interface, increased memory
288	  efficiency.  (intertwined patch, committed all together)
289	  <http://lists.danga.com/pipermail/memcached/2006-May/002164.html>
290	  or see svn commit logs
291
2922006-04-30
293	* River Tarnell:  autoconf work for Solaris 10.  Brad:
294	merge and verify it works on Nexenta.
295
2962006-03-04
297	* avva: bucket/generation patch (old, but Brad's just finally
298	committing it)
299
3002006-01-01
301	* Brad Fitzpatrick <[email protected]>:  allocate 1 slab per class
302	on start-up, to avoid confusing users with out-of-memory errors
303	later.  this is 18 MB of allocation on start, unless max memory
304	allowed with -m is lower, in which case only the smaller slab
305	classes are allocated.
306
3072005-08-09
308	* Elizabeth Mattijsen <[email protected]>: needed a way to flush all
309	memcached backend servers, but not at exactly the same time (to
310	reduce load peaks), I've added some simple functionality to the
311	memcached protocol in the "flush_all" command that allows you to
312	specify a time at which the flush will actually occur (instead of
313	always at the moment the "flush_all" command is received).
314
3152005-05-25
316	* patch from Peter van Dijk <[email protected]> to make
317	  stderr unbuffered, for running under daemontools
318
3192005-04-04
320	* patch from Don MacAskill <[email protected]> 'flush_all' doesn't
321	seem to work properly.  Basically, if you try to add a key which
322	is present, but expired, the store fails but the old key is no
323	longer expired.
324
325	* release 1.1.12
326
3272005-01-14
328	* Date: Thu, 18 Nov 2004 15:25:59 -0600
329	  From: David Phillips <[email protected]>
330	Here is a patch to configure.ac and Makefile.am to put the man page in
331	the correct location.  Trying to install the man page from a
332	subdirectory results in the subdirectory being used in the install
333	path (it tries to install to doc/memcached.1).  This is the correct
334	thing to  do:
335
336	- create a Makefile.am in the doc directory that installs the man page
337	  with man_MANS
338	- modify Makefile.am in the base directory to reference the doc
339  	  directory using SUBDIRS
340	- modify the AC_CONFIG_FILES macro in configure.ac to output the
341	  Makefile in doc
342
343
3442005-01-14
345	* pidfile saving support from Lisa Seelye <[email protected]>, sent
346	  Jan 13, 2005
347
3482005-01-14
349	* don't delete libevent events that haven't been added (the deltimer)
350	  patch from Ted Schundler <[email protected]>
351
3522004-12-10
353	* document -M and -r in manpage (Doug Porter <[email protected]>)
354
3552004-07-22
356	* fix buffer overflow in items.c with 250 byte keys along with
357	  other info on the same line going into a 256 byte char[].
358	  thanks to Andrei Nigmatulin <[email protected]>
359
3602004-06-15
361	* immediate deletes weren't being unlinked a few seconds,
362	  preventing "add" commands to the same key in that time period.
363	  thanks to Michael Alan Dorman <[email protected]> for the
364	  bug report and demo script.
365
3662004-04-30
367	* released 1.1.11
368
3692004-04-24
370	* Avva: Add a new command line option: -r , to maximize core file
371	limit.
372
3732004-03-31
374	* Avva: Use getrlimit and setrlimit to set limits for number of
375	simultaneously open file descriptors. Get the current limits and
376	try to raise them if they're not enough for the specified (or the
377	default) setting of max connections.
378
3792004-02-24
380	* Adds a '-M' flag to turn off tossing items from the cache.
381	  (Jason Titus <[email protected]>)
382
3832004-02-19 (Evan)
384	* Install manpage on "make install", etc.
385
3862003-12-30 (Brad)
387	* remove static build stuff.  interferes with PAM setuid stuff
388	  and was only included as a possible fix with the old memory
389	  allocator.  really shouldn't make a difference.
390	* add Jay Bonci's Debian scripts and manpage
391	* release version 1.1.10
392
3932003-12-01 (Avva)
394	* New command: flush_all, causes all existing items to
395	  be invalidated immediately (without deleting them from
396	  memory, merely causing memcached to no longer return them).
3972003-10-23
398	* Shift init code around to fix daemon mode on FreeBSD,
399	* and drop root only after creating the server socket (to
400	* allow the use of privileged ports)
401	* version 1.1.10pre
402
4032003-10-09
404	* BSD compile fixes from Ryan T. Dean
405	* version 1.1.9
406
4072003-09-29
408	* ignore SIGPIPE at start instead of crashing in rare cases it
409	  comes up.  no other code had to be modified, since everything
410	  else is already dead-connection-aware.  (avva)
411
4122003-09-09 (Avva, Lisa Marie Seelye <[email protected]>)
413	* setuid support
414
4152003-09-05 (Avva)
416	* accept all new connections in the same event (so we work with ET epoll)
417	* mark all items as clsid=0 after slab page reassignment to please future
418	  asserts (on the road to making slab page reassignment work fully)
419
4202003-08-12 (Brad Fitzpatrick)
421	* use TCP_CORK on Linux or TCP_PUSH on BSD
422	* only use TCP_NODELAY when we don't have alternatives
423
4242003-08-10
425	* disable Nagel's Algorithm (TCP_NODELAY) for better performance (avva)
426
4272003-08-10
428	* support multiple levels of verbosity (-vv)
429
4302003-08-10  (Evan Martin)
431	* Makefile.am: debug, optimization, and static flags are controlled
432	  by the configure script.
433	* configure.ac:
434	  - allow specifying libevent directory with --with-libevent=DIR
435	  - check for malloc.h (unavailable on BSDs)
436	  - check for socklen_t (unavailable on OSX)
437	* assoc.c, items.c, slabs.c:  Remove some unused headers.
438	* memcached.c:  allow for nonexistence of malloc.h; #define a POSIX
439	  macro to import mlockall flags.
440
4412003-07-29
442	* version 1.1.7
443	* big bug fix: item exptime 0 meant expire immediately, not never
444	* version 1.1.8
445
4462003-07-22
447	* make 'delete' take second arg, of time to refuse new add/replace
448	* set/add/replace/delete can all take abs or delta time (delta can't
449	  be larger than a month)
450
4512003-07-21
452	* added doc/protocol.txt
453
4542003-07-01

459	* fix a number of obscure bugs
460	* more stats reporting

487
488	* configure.ac, autogen.sh, Makefile.am:  Use autotools.
489	* items.c, memcached.c:  #include <time.h> for time(),
490	  printf time_t as %lu (is this correct?),
491	  minor warnings fixes.
