Thanks to Adam Dixon 225 <[email protected]> for the bug report and test case! 226 2272006-11-26 228 * Steven Grimm <[email protected]>: Performance improvements: 229 230 Dynamic sizing of hashtable to reduce collisions on very large 231 caches and conserve memory on small caches. 232 233 Only reposition items in the LRU queue once a minute, to reduce 234 overhead of accessing extremely frequently-used items. 235 236 Stop listening for new connections until an existing one closes 237 if we run out of available file descriptors. 238 239 Command parser refactoring: Add a single-pass tokenizer to cut 240 down on string scanning. Split the command processing into 241 separate functions for easier profiling and better readability. 242 Pass key lengths along with the keys in all API functions that 243 need keys, to avoid needing to call strlen() repeatedly. 244 2452006-11-25 246 * Steve Peters <[email protected]>: OpenBSD has a malloc.h, 247 but warns to use stdlib.h instead 248 2492006-11-22 250 * Steven Grimm <[email protected]>: Add support for multithreaded 251 execution.

(intertwined patch, committed all together) 300 <http://lists.danga.com/pipermail/memcached/2006-May/002164.html> 301 or see svn commit logs 302 3032006-04-30 304 * River Tarnell: autoconf work for Solaris 10. Brad: 305 merge and verify it works on Nexenta. 306 3072006-03-04 308 * avva: bucket/generation patch (old, but Brad's just finally 309 committing it) 310 3112006-01-01 312 * Brad Fitzpatrick <[email protected]>: allocate 1 slab per class 313 on start-up, to avoid confusing users with out-of-memory errors 314 later. this is 18 MB of allocation on start, unless max memory 315 allowed with -m is lower, in which case only the smaller slab 316 classes are allocated. 317 3182005-08-09 319 * Elizabeth Mattijsen <[email protected]>: needed a way to flush all 320 memcached backend servers, but not at exactly the same time (to 321 reduce load peaks), I've added some simple functionality to the 322 memcached protocol in the "flush_all" command that allows you to 323 specify a time at which the flush will actually occur (instead of 324 always at the moment the "flush_all" command is received). 325 3262005-05-25 327 * patch from Peter van Dijk <[email protected]> to make 328 stderr unbuffered, for running under daemontools 329 3302005-04-04 331 * patch from Don MacAskill <[email protected]> 'flush_all' doesn't 332 seem to work properly. Basically, if you try to add a key which 333 is present, but expired, the store fails but the old key is no 334 longer expired. 335 336 * release 1.1.12 337 3382005-01-14 339 * Date: Thu, 18 Nov 2004 15:25:59 -0600 340 From: David Phillips <[email protected]> 341 Here is a patch to configure.ac and Makefile.am to put the man page in 342 the correct location. Trying to install the man page from a 343 subdirectory results in the subdirectory being used in the install 344 path (it tries to install to doc/memcached.1). This is the correct 345 thing to do: 346 347 - create a Makefile.am in the doc directory that installs the man page 348 with man_MANS 349 - modify Makefile.am in the base directory to reference the doc 350 directory using SUBDIRS 351 - modify the AC_CONFIG_FILES macro in configure.ac to output the 352 Makefile in doc 353 354 3552005-01-14 356 * pidfile saving support from Lisa Seelye <[email protected]>, sent 357 Jan 13, 2005 358 3592005-01-14 360 * don't delete libevent events that haven't been added (the deltimer) 361 patch from Ted Schundler <[email protected]> 362 3632004-12-10 364 * document -M and -r in manpage (Doug Porter <[email protected]>) 365 3662004-07-22 367 * fix buffer overflow in items.c with 250 byte keys along with 368 other info on the same line going into a 256 byte char[]. 369 thanks to Andrei Nigmatulin <[email protected]> 370 3712004-06-15 372 * immediate deletes weren't being unlinked a few seconds, 373 preventing "add" commands to the same key in that time period. 374 thanks to Michael Alan Dorman <[email protected]> for the 375 bug report and demo script. 376 3772004-04-30 378 * released 1.1.11 379 3802004-04-24 381 * Avva: Add a new command line option: -r , to maximize core file 382 limit. 383 3842004-03-31 385 * Avva: Use getrlimit and setrlimit to set limits for number of 386 simultaneously open file descriptors. Get the current limits and 387 try to raise them if they're not enough for the specified (or the 388 default) setting of max connections. 389 3902004-02-24 391 * Adds a '-M' flag to turn off tossing items from the cache. 392 (Jason Titus <[email protected]>) 393 3942004-02-19 (Evan) 395 * Install manpage on "make install", etc. 396 3972003-12-30 (Brad) 398 * remove static build stuff. interferes with PAM setuid stuff 399 and was only included as a possible fix with the old memory 400 allocator. really shouldn't make a difference. 401 * add Jay Bonci's Debian scripts and manpage 402 * release version 1.1.10 403 4042003-12-01 (Avva) 405 * New command: flush_all, causes all existing items to 406 be invalidated immediately (without deleting them from 407 memory, merely causing memcached to no longer return them). 4082003-10-23 409 * Shift init code around to fix daemon mode on FreeBSD, 410 * and drop root only after creating the server socket (to 411 * allow the use of privileged ports) 412 * version 1.1.10pre 413 4142003-10-09 415 * BSD compile fixes from Ryan T. Dean 416 * version 1.1.9 417 4182003-09-29 419 * ignore SIGPIPE at start instead of crashing in rare cases it 420 comes up. no other code had to be modified, since everything 421 else is already dead-connection-aware. (avva) 422 4232003-09-09 (Avva, Lisa Marie Seelye <[email protected]>) 424 * setuid support 425 4262003-09-05 (Avva) 427 * accept all new connections in the same event (so we work with ET epoll) 428 * mark all items as clsid=0 after slab page reassignment to please future 429 asserts (on the road to making slab page reassignment work fully) 430 4312003-08-12 (Brad Fitzpatrick) 432 * use TCP_CORK on Linux or TCP_PUSH on BSD 433 * only use TCP_NODELAY when we don't have alternatives 434 4352003-08-10 436 * disable Nagel's Algorithm (TCP_NODELAY) for better performance (avva) 437 4382003-08-10 439 * support multiple levels of verbosity (-vv) 440 4412003-08-10 (Evan Martin) 442 * Makefile.am: debug, optimization, and static flags are controlled 443 by the configure script. 444 * configure.ac: 445 - allow specifying libevent directory with --with-libevent=DIR 446 - check for malloc.h (unavailable on BSDs) 447 - check for socklen_t (unavailable on OSX) 448 * assoc.c, items.c, slabs.c: Remove some unused headers. 449 * memcached.c: allow for nonexistence of malloc.h; #define a POSIX 450 macro to import mlockall flags. 451 4522003-07-29 453 * version 1.1.7 454 * big bug fix: item exptime 0 meant expire immediately, not never 455 * version 1.1.8 456 4572003-07-22 458 * make 'delete' take second arg, of time to refuse new add/replace 459 * set/add/replace/delete can all take abs or delta time (delta can't 460 be larger than a month) 461 4622003-07-21 463 * added doc/protocol.txt 464 4652003-07-01 466 * report CPU usage in stats 467 4682003-06-30 469 * version 1.1.6 470 * fix a number of obscure bugs 471 * more stats reporting 472 4732003-06-10 474 * removing use of Judy; use a hash.
