|
|
|
87 2007-03-05 Paul Lindner <lindner@inuus.com>
|
|
|
88 * Fix a number of places where (s)printf calls were using unsigned
|
|
|
89 or signed formats that did not match their arguments.
|
|
|
90
|
|
|
91 * Add support for stdbool.h and stdint.h to use the bool and
|
|
|
92 uint8_t types.
|
|
|
93
|
|
|
94 * Major refactoring - move API calls for assoc/items/slabs to
|
|
|
95 their own individual header files. Add apropriate const and
|
|
|
96 static declarations as appropriate.
|
|
|
97
|
|
|
98 * Avoid type-punning. Do a more efficient realloc inside the

|
|
99 conn_shrink routine.
|
|
|
100
|
|
|
101 * Fix overflow bug where uninitialized access to slabclass caused

|
|
108
|
|
|
109 * Explicitly compare against NULL or zero in many places.

|
|
|
112 * Steven Grimm <sgrimm@facebook.com>: Per-object-type stats collection
|
|
|
113 support. Specify the object type delimiter with the -D command line
|
|
|
114 option. Turn stats gathering on and off with "stats detail on" and
|
|
|
115 "stats detail off". Dump the per-object-type details with
|
|
|
116 "stats detail dump".
|

118 2007-03-01

|
|
|
123 * fix expirations of items set with absolute expiration times in
|
|
|
124 the past, before the server's start time. bug was introduced in
|
|
|
125 1.2.0 with rel_time_t. Thanks to Adam Dixon
|
|
|
126 <adamtdixon@gmail.com> for the bug report and test case!

|
|
129 * Steven Grimm <sgrimm@facebook.com>: Performance improvements:
|
|
|
130
|
|
|
131 Dynamic sizing of hashtable to reduce collisions on very large
|
|
|
132 caches and conserve memory on small caches.
|
|
|
133
|
|
|
134 Only reposition items in the LRU queue once a minute, to reduce
|
|
|
135 overhead of accessing extremely frequently-used items.
|
|
|
136
|
|
|
137 Stop listening for new connections until an existing one closes
|
|
|
138 if we run out of available file descriptors.
|
|
|
139
|
|
|
140 Command parser refactoring: Add a single-pass tokenizer to cut
|
|
|
141 down on string scanning. Split the command processing into
|
|
|
142 separate functions for easier profiling and better readability.
|
|
|
143 Pass key lengths along with the keys in all API functions that
|
|
|
144 need keys, to avoid needing to call strlen() repeatedly.

|
147 * Steve Peters <steve@fisharerojo.org>: OpenBSD has a malloc.h,

148 but warns to use stdlib.h instead
|
|
|
149
|
|
|
150 2006-11-22
|
|
|
151 * Steven Grimm <sgrimm@facebook.com>: Add support for multithreaded

|
|
|
167 2006-09-20

|
|
|
170
|
|
|
171 2006-09-09
|
|
|
172 * release 1.2.0 (along with 1.1.13, which is the more tested branch)
|
|
|
173
|
|
|
174 nobody has run 1.2.0 in production, to my knowledge. facebook has run
|
|
|
175 their pre-merge-with-trunk version, but bugs were discovered (and fixed)
|
|
|
176 after the merge. there might be more. you've been warned. :)
|
|
|
177
|
|
|
178 2006-09-04

211
|

212 2006-01-01
|
|
|
213 * Brad Fitzpatrick <brad@danga.com>: allocate 1 slab per class
|
|
|
214 on start-up, to avoid confusing users with out-of-memory errors
|
|
|
215 later. this is 18 MB of allocation on start, unless max memory
|
|
|
216 allowed with -m is lower, in which case only the smaller slab
|
|
|
217 classes are allocated.

|
|
218
|
|
|
219 2005-08-09
|
|
|
220 * Elizabeth Mattijsen <liz@dijkmat.nl>: needed a way to flush all
|
|
|
221 memcached backend servers, but not at exactly the same time (to
|
|
|
222 reduce load peaks), I've added some simple functionality to the
|
|
|
223 memcached protocol in the "flush_all" command that allows you to
|
|
|
224 specify a time at which the flush will actually occur (instead of
|
|
|
225 always at the moment the "flush_all" command is received).
|
|
|
226
|
|
|
227 2005-05-25
|
|
|
228 * patch from Peter van Dijk <peter@nextgear.nl> to make
|
|
|
229 stderr unbuffered, for running under daemontools
|
|
|
230
|
|
|
231 2005-04-04
|
|
|
232 * patch from Don MacAskill <don@smugmug.com> 'flush_all' doesn't
|
|
|
233 seem to work properly. Basically, if you try to add a key which
|
|
|
234 is present, but expired, the store fails but the old key is no
|
|
|
235 longer expired.
|
|
|
236
|
|
|
237 * release 1.1.12
|
|
|

240 * Date: Thu, 18 Nov 2004 15:25:59 -0600
|
|
|
241 From: David Phillips <electrum@gmail.com>
|
|
|
242 Here is a patch to configure.ac and Makefile.am to put the man page in
|
|
|
243 the correct location. Trying to install the man page from a
|
|
|
244 subdirectory results in the subdirectory being used in the install
|
|
|
245 path (it tries to install to doc/memcached.1). This is the correct
|
|
|
246 thing to do:
|
|
|
247
|
|
|
248 - create a Makefile.am in the doc directory that installs the man page
|
|
|
249 with man_MANS
|
|
|
250 - modify Makefile.am in the base directory to reference the doc
|
|
|
251 directory using SUBDIRS
|
|
|
252 - modify the AC_CONFIG_FILES macro in configure.ac to output the
|
|
|
253 Makefile in doc
|
|
|
254
|
|
|
255
|
|
|
256 2005-01-14
|
|
|
257 * pidfile saving support from Lisa Seelye <lisa@gentoo.org>, sent
|
|
|
258 Jan 13, 2005
|
|
|
259
|
|
|
260 2005-01-14
|
|
|
261 * don't delete libevent events that haven't been added (the deltimer)
|
|
|
262 patch from Ted Schundler <tschundler@gmail.com>
|
|
|
263
|
|
|
264 2004-12-10
|
|
|
265 * document -M and -r in manpage (Doug Porter <dsp@dsp.name>)
|
|
|
266
|
|
|
267 2004-07-22
|
|
|
268 * fix buffer overflow in items.c with 250 byte keys along with
|
|
|
269 other info on the same line going into a 256 byte char[].
|
|
|
270 thanks to Andrei Nigmatulin <anight@monamour.ru>
|
|
|
271
|
|
|
272 2004-06-15
|
|
|
273 * immediate deletes weren't being unlinked a few seconds,
|
|
|
274 preventing "add" commands to the same key in that time period.
|
|
|
275 thanks to Michael Alan Dorman <mdorman@debian.org> for the
|
|
|
276 bug report and demo script.
|
|
|
277
|
|
|
278 2004-04-30
|
|
|
279 * released 1.1.11
|
|
|
280
|
|
|
281 2004-04-24
|
|
|
282 * Avva: Add a new command line option: -r , to maximize core file
|
|
|
283 limit.
|
|
|
284
|
|
|
285 2004-03-31
|
|
|
286 * Avva: Use getrlimit and setrlimit to set limits for number of
|
|
|
287 simultaneously open file descriptors. Get the current limits and
|
|
|
288 try to raise them if they're not enough for the specified (or the
|
|
|
289 default) setting of max connections.
|
|
|
290
|
|
|
291 2004-02-24
|
|
|
292 * Adds a '-M' flag to turn off tossing items from the cache.

|
|
294
|
|
|
295 2004-02-19 (Evan)
|
|
|
296 * Install manpage on "make install", etc.
|
|
|
297
|
|
|
298 2003-12-30 (Brad)
|
|
|
299 * remove static build stuff. interferes with PAM setuid stuff
|
|
|
300 and was only included as a possible fix with the old memory
|
|
|
301 allocator. really shouldn't make a difference.
|
|
|
302 * add Jay Bonci's Debian scripts and manpage
|
|
|
303 * release version 1.1.10
|
|
|
304
|
|
|
305 2003-12-01 (Avva)
|
|
|
306 * New command: flush_all, causes all existing items to
|
|
|
307 be invalidated immediately (without deleting them from
|
|
|
308 memory, merely causing memcached to no longer return them).
|
|
|
309 2003-10-23
|
|
|
310 * Shift init code around to fix daemon mode on FreeBSD,
|
|
|
311 * and drop root only after creating the server socket (to
|
|
|
312 * allow the use of privileged ports)
|
|
|
313 * version 1.1.10pre
|
|
|
314
|
|
|
315 2003-10-09
|
|
|
316 * BSD compile fixes from Ryan T. Dean
|
|
|
317 * version 1.1.9
|
|
|
318
|
|
|
319 2003-09-29
|
|
|
320 * ignore SIGPIPE at start instead of crashing in rare cases it
|
|
|
321 comes up. no other code had to be modified, since everything
|
|
|
322 else is already dead-connection-aware. (avva)
|
|
|
323
|
|
|
324 2003-09-09 (Avva, Lisa Marie Seelye <lisa@gentoo.org>)
|
|
|
325 * setuid support
|
|
|
326
|
|
|
327 2003-09-05 (Avva)
|
|
|
328 * accept all new connections in the same event (so we work with ET epoll)
|
|
|
329 * mark all items as clsid=0 after slab page reassignment to please future
|
|
|
330 asserts (on the road to making slab page reassignment work fully)
|
|
|
331
|
|
|
332 2003-08-12 (Brad Fitzpatrick)
|
|
|
333 * use TCP_CORK on Linux or TCP_PUSH on BSD
|
|
|
334 * only use TCP_NODELAY when we don't have alternatives
|
|
|
335
|
