902007-10-15  Paul Lindner  <[email protected]>
91
92	* Patch from David Bremner <[email protected]> that implements
93	  a new option "-a" which takes an octal permission mask

96
972007-10-03 Paul Lindner <[email protected]>

122	  Patch from Maxim Dounin <[email protected]>
123
1242007-08-21 Paul Lindner <[email protected]>
125	* Incorporate incrememnt patch from Evan Miller

185	  "verbosity" command and some compiler cleanups.
186          Patch contributed by Paolo Borelli <[email protected]>.
187
1882007-04-08  Paul Lindner  <[email protected]>
189
190	* Add cleanup patch from "Tim Yardley" <[email protected]> to
191	  clean up source spacing issues, fix -Wall warnings, add some

193	  use of conn *c without checking to see if c is NULL first.
194
195        * Also adjust clean-whitespace.pl to clean *.ac files.  Add
196          script to test-suite to test for tabs.
197
1982007-04-04  Paul Lindner  <[email protected]>
199

202
2032007-03-31  Paul Lindner  <[email protected]>

2252007-03-17
226	* crash fix from Thomas van Gulick <[email protected]> in
227	  conn_shrink(), passing &ptr, instead of ptr to realloc().
228
2292007-03-05  Paul Lindner  <[email protected]>
230	* Fix a number of places where (s)printf calls were using unsigned
231	  or signed formats that did not match their arguments.
232
233	* Add support for stdbool.h and stdint.h to use the bool and
234	  uint8_t types.
235
236	* Major refactoring - move API calls for assoc/items/slabs to
237	  their own individual header files.  Add apropriate const and
238	  static declarations as appropriate.
239
240	* Avoid type-punning.  Do a more efficient realloc inside the
241	  conn_shrink routine.
242
243        * Fix overflow bug where uninitialized access to slabclass caused
244	  size-0 mallocs during slab preallocation.
245
246	* Use EXIT_SUCCESS/EXIT_FAILURE constants.
247
248	* Convert some sprintf calls to snprintf to protect against
249	  buffer overflows.
250
251	* Explicitly compare against NULL or zero in many places.
252
2532007-03-05
254	* Steven Grimm <[email protected]>: Per-object-type stats collection
255	  support. Specify the object type delimiter with the -D command line
256	  option. Turn stats gathering on and off with "stats detail on" and
257	  "stats detail off". Dump the per-object-type details with
258	  "stats detail dump".
259
2602007-03-01
261	* Steven Grimm <[email protected]>: Fix an off-by-one error in the
262	  multithreaded version's message passing code.
263
2642006-12-23
265	* fix expirations of items set with absolute expiration times in
266	  the past, before the server's start time.  bug was introduced in
267	  1.2.0 with rel_time_t.  Thanks to Adam Dixon
268	  <[email protected]> for the bug report and test case!
269
2702006-11-26
271	* Steven Grimm <[email protected]>: Performance improvements:
272
273	  Dynamic sizing of hashtable to reduce collisions on very large
274	  caches and conserve memory on small caches.
275
276	  Only reposition items in the LRU queue once a minute, to reduce
277	  overhead of accessing extremely frequently-used items.
278
279	  Stop listening for new connections until an existing one closes
280	  if we run out of available file descriptors.
281
282	  Command parser refactoring: Add a single-pass tokenizer to cut
283	  down on string scanning.  Split the command processing into
284	  separate functions for easier profiling and better readability.
285	  Pass key lengths along with the keys in all API functions that
286	  need keys, to avoid needing to call strlen() repeatedly.
287
2882006-11-25
289	* Steve Peters <[email protected]>: OpenBSD has a malloc.h,
290	but warns to use stdlib.h instead
291
2922006-11-22
293	* Steven Grimm <[email protected]>: Add support for multithreaded
294	  execution. Run configure with "--enable-threads" to enable. See
295	  doc/threads.txt for details.
296
2972006-11-13
298	* Iain Wade <[email protected]>: Fix for UDP responses on non-"get"
299	 commands.
300
3012006-10-15
302	* Steven Grimm <[email protected]>: Dynamic sizing of hashtable to
303	  reduce collisions on very large caches and conserve memory on
304	  small caches.
305
3062006-10-13
307	* Steven Grimm <[email protected]>: New faster hash function.
308
3092006-09-20
310
311	* don't listen on UDP by default; more clear message when UDP port in use
312
3132006-09-09
314	* release 1.2.0 (along with 1.1.13, which is the more tested branch)
315
316	nobody has run 1.2.0 in production, to my knowledge.  facebook has run
317	their pre-merge-with-trunk version, but bugs were discovered (and fixed)
318	after the merge.  there might be more.  you've been warned.  :)
319
3202006-09-04
321	* improved autoconf libevent detection, from the Tor project.
322
3232006-09-03
324	* test suite and lot of expiration, delete, flush_all, etc corner
325	  case bugs fixed (Brad Fitzpatrick)
326
3272006-09-02
328	* Nathan Neulinger <[email protected]>: fix breakage in expiration code
329	  causing expiration times to not be processed correctly.
330
3312006-08-21
332	* Nathan Neulinger <[email protected]>: fix incompatabilities with
333	  unix domain socket support and the UDP code and clean up stale
334	  sockets
335
3362006-08-20
337	* Nathan Neulinger <[email protected]>: unix domain socket support
338
3392006-05-03
340	* Steven Grimm <[email protected]>:  big bunch of changes:
341	  big CPU reduction work, UDP-based interface, increased memory
342	  efficiency.  (intertwined patch, committed all together)
343	  <http://lists.danga.com/pipermail/memcached/2006-May/002164.html>
344	  or see svn commit logs
345
3462006-04-30
347	* River Tarnell:  autoconf work for Solaris 10.  Brad:
348	merge and verify it works on Nexenta.
349
3502006-03-04
351	* avva: bucket/generation patch (old, but Brad's just finally
352	committing it)
353
3542006-01-01
355	* Brad Fitzpatrick <[email protected]>:  allocate 1 slab per class
356	on start-up, to avoid confusing users with out-of-memory errors
357	later.  this is 18 MB of allocation on start, unless max memory
358	allowed with -m is lower, in which case only the smaller slab
359	classes are allocated.
360
3612005-08-09
362	* Elizabeth Mattijsen <[email protected]>: needed a way to flush all
363	memcached backend servers, but not at exactly the same time (to
364	reduce load peaks), I've added some simple functionality to the
365	memcached protocol in the "flush_all" command that allows you to
366	specify a time at which the flush will actually occur (instead of
367	always at the moment the "flush_all" command is received).
368
3692005-05-25
370	* patch from Peter van Dijk <[email protected]> to make
371	  stderr unbuffered, for running under daemontools
372
3732005-04-04
374	* patch from Don MacAskill <[email protected]> 'flush_all' doesn't
375	seem to work properly.  Basically, if you try to add a key which
376	is present, but expired, the store fails but the old key is no
377	longer expired.
378
379	* release 1.1.12
380
3812005-01-14
382	* Date: Thu, 18 Nov 2004 15:25:59 -0600
383	  From: David Phillips <[email protected]>
384	Here is a patch to configure.ac and Makefile.am to put the man page in
385	the correct location.  Trying to install the man page from a
386	subdirectory results in the subdirectory being used in the install
387	path (it tries to install to doc/memcached.1).  This is the correct
388	thing to  do:
389
390	- create a Makefile.am in the doc directory that installs the man page
391	  with man_MANS
392	- modify Makefile.am in the base directory to reference the doc
393  	  directory using SUBDIRS
394	- modify the AC_CONFIG_FILES macro in configure.ac to output the
395	  Makefile in doc
396
397
3982005-01-14
399	* pidfile saving support from Lisa Seelye <[email protected]>, sent
400	  Jan 13, 2005
401
4022005-01-14
403	* don't delete libevent events that haven't been added (the deltimer)
404	  patch from Ted Schundler <[email protected]>
405
4062004-12-10
407	* document -M and -r in manpage (Doug Porter <[email protected]>)
408
4092004-07-22
410	* fix buffer overflow in items.c with 250 byte keys along with
411	  other info on the same line going into a 256 byte char[].
412	  thanks to Andrei Nigmatulin <[email protected]>
413
4142004-06-15
415	* immediate deletes weren't being unlinked a few seconds,
416	  preventing "add" commands to the same key in that time period.
417	  thanks to Michael Alan Dorman <[email protected]> for the
418	  bug report and demo script.
419
4202004-04-30
421	* released 1.1.11
422
4232004-04-24
424	* Avva: Add a new command line option: -r , to maximize core file
425	limit.
426
4272004-03-31
428	* Avva: Use getrlimit and setrlimit to set limits for number of
429	simultaneously open file descriptors. Get the current limits and
430	try to raise them if they're not enough for the specified (or the
431	default) setting of max connections.
432
4332004-02-24
434	* Adds a '-M' flag to turn off tossing items from the cache.
435	  (Jason Titus <[email protected]>)
436
4372004-02-19 (Evan)
438	* Install manpage on "make install", etc.
439
4402003-12-30 (Brad)
441	* remove static build stuff.  interferes with PAM setuid stuff
442	  and was only included as a possible fix with the old memory
443	  allocator.  really shouldn't make a difference.
444	* add Jay Bonci's Debian scripts and manpage
445	* release version 1.1.10
446
4472003-12-01 (Avva)
448	* New command: flush_all, causes all existing items to
449	  be invalidated immediately (without deleting them from
450	  memory, merely causing memcached to no longer return them).
4512003-10-23
452	* Shift init code around to fix daemon mode on FreeBSD,
453	* and drop root only after creating the server socket (to
454	* allow the use of privileged ports)
455	* version 1.1.10pre
456
4572003-10-09
458	* BSD compile fixes from Ryan T. Dean
459	* version 1.1.9
460
4612003-09-29
462	* ignore SIGPIPE at start instead of crashing in rare cases it
463	  comes up.  no other code had to be modified, since everything
464	  else is already dead-connection-aware.  (avva)
465
4662003-09-09 (Avva, Lisa Marie Seelye <[email protected]>)
467	* setuid support
468
4692003-09-05 (Avva)
470	* accept all new connections in the same event (so we work with ET epoll)
471	* mark all items as clsid=0 after slab page reassignment to please future
472	  asserts (on the road to making slab page reassignment work fully)
473
4742003-08-12 (Brad Fitzpatrick)
475	* use TCP_CORK on Linux or TCP_PUSH on BSD
476	* only use TCP_NODELAY when we don't have alternatives
477
4782003-08-10
479	* disable Nagel's Algorithm (TCP_NODELAY) for better performance (avva)
480
4812003-08-10
482	* support multiple levels of verbosity (-vv)
483
4842003-08-10  (Evan Martin)
485	* Makefile.am: debug, optimization, and static flags are controlled
486	  by the configure script.
487	* configure.ac:
488	  - allow specifying libevent directory with --with-libevent=DIR
489	  - check for malloc.h (unavailable on BSDs)
490	  - check for socklen_t (unavailable on OSX)
491	* assoc.c, items.c, slabs.c:  Remove some unused headers.
492	* memcached.c:  allow for nonexistence of malloc.h; #define a POSIX
493	  macro to import mlockall flags.
494
4952003-07-29
496	* version 1.1.7
497	* big bug fix: item exptime 0 meant expire immediately, not never
498	* version 1.1.8
499
5002003-07-22
501	* make 'delete' take second arg, of time to refuse new add/replace
502	* set/add/replace/delete can all take abs or delta time (delta can't
503	  be larger than a month)
504
5052003-07-21
506	* added doc/protocol.txt
507
5082003-07-01
509	* report CPU usage in stats
510
5112003-06-30
512	* version 1.1.6
513	* fix a number of obscure bugs
