Split the command processing into 255 separate functions for easier profiling and better readability. 256 Pass key lengths along with the keys in all API functions that 257 need keys, to avoid needing to call strlen() repeatedly. 258 2592006-11-25 260 * Steve Peters <[email protected]>: OpenBSD has a malloc.h, 261 but warns to use stdlib.h instead 262 2632006-11-22 264 * Steven Grimm <[email protected]>: Add support for multithreaded 265 execution.

(intertwined patch, committed all together) 314 <http://lists.danga.com/pipermail/memcached/2006-May/002164.html> 315 or see svn commit logs 316 3172006-04-30 318 * River Tarnell: autoconf work for Solaris 10. Brad: 319 merge and verify it works on Nexenta. 320 3212006-03-04 322 * avva: bucket/generation patch (old, but Brad's just finally 323 committing it) 324 3252006-01-01 326 * Brad Fitzpatrick <[email protected]>: allocate 1 slab per class 327 on start-up, to avoid confusing users with out-of-memory errors 328 later. this is 18 MB of allocation on start, unless max memory 329 allowed with -m is lower, in which case only the smaller slab 330 classes are allocated. 331 3322005-08-09 333 * Elizabeth Mattijsen <[email protected]>: needed a way to flush all 334 memcached backend servers, but not at exactly the same time (to 335 reduce load peaks), I've added some simple functionality to the 336 memcached protocol in the "flush_all" command that allows you to 337 specify a time at which the flush will actually occur (instead of 338 always at the moment the "flush_all" command is received). 339 3402005-05-25 341 * patch from Peter van Dijk <[email protected]> to make 342 stderr unbuffered, for running under daemontools 343 3442005-04-04 345 * patch from Don MacAskill <[email protected]> 'flush_all' doesn't 346 seem to work properly. Basically, if you try to add a key which 347 is present, but expired, the store fails but the old key is no 348 longer expired. 349 350 * release 1.1.12 351 3522005-01-14 353 * Date: Thu, 18 Nov 2004 15:25:59 -0600 354 From: David Phillips <[email protected]> 355 Here is a patch to configure.ac and Makefile.am to put the man page in 356 the correct location. Trying to install the man page from a 357 subdirectory results in the subdirectory being used in the install 358 path (it tries to install to doc/memcached.1). This is the correct 359 thing to do: 360 361 - create a Makefile.am in the doc directory that installs the man page 362 with man_MANS 363 - modify Makefile.am in the base directory to reference the doc 364 directory using SUBDIRS 365 - modify the AC_CONFIG_FILES macro in configure.ac to output the 366 Makefile in doc 367 368 3692005-01-14 370 * pidfile saving support from Lisa Seelye <[email protected]>, sent 371 Jan 13, 2005 372 3732005-01-14 374 * don't delete libevent events that haven't been added (the deltimer) 375 patch from Ted Schundler <[email protected]> 376 3772004-12-10 378 * document -M and -r in manpage (Doug Porter <[email protected]>) 379 3802004-07-22 381 * fix buffer overflow in items.c with 250 byte keys along with 382 other info on the same line going into a 256 byte char[]. 383 thanks to Andrei Nigmatulin <[email protected]> 384 3852004-06-15 386 * immediate deletes weren't being unlinked a few seconds, 387 preventing "add" commands to the same key in that time period. 388 thanks to Michael Alan Dorman <[email protected]> for the 389 bug report and demo script. 390 3912004-04-30 392 * released 1.1.11 393 3942004-04-24 395 * Avva: Add a new command line option: -r , to maximize core file 396 limit. 397 3982004-03-31 399 * Avva: Use getrlimit and setrlimit to set limits for number of 400 simultaneously open file descriptors. Get the current limits and 401 try to raise them if they're not enough for the specified (or the 402 default) setting of max connections. 403 4042004-02-24 405 * Adds a '-M' flag to turn off tossing items from the cache. 406 (Jason Titus <[email protected]>) 407 4082004-02-19 (Evan) 409 * Install manpage on "make install", etc. 410 4112003-12-30 (Brad) 412 * remove static build stuff. interferes with PAM setuid stuff 413 and was only included as a possible fix with the old memory 414 allocator. really shouldn't make a difference. 415 * add Jay Bonci's Debian scripts and manpage 416 * release version 1.1.10 417 4182003-12-01 (Avva) 419 * New command: flush_all, causes all existing items to 420 be invalidated immediately (without deleting them from 421 memory, merely causing memcached to no longer return them). 4222003-10-23 423 * Shift init code around to fix daemon mode on FreeBSD, 424 * and drop root only after creating the server socket (to 425 * allow the use of privileged ports) 426 * version 1.1.10pre 427 4282003-10-09 429 * BSD compile fixes from Ryan T. Dean 430 * version 1.1.9 431 4322003-09-29 433 * ignore SIGPIPE at start instead of crashing in rare cases it 434 comes up. no other code had to be modified, since everything 435 else is already dead-connection-aware. (avva) 436 4372003-09-09 (Avva, Lisa Marie Seelye <[email protected]>) 438 * setuid support 439 4402003-09-05 (Avva) 441 * accept all new connections in the same event (so we work with ET epoll) 442 * mark all items as clsid=0 after slab page reassignment to please future 443 asserts (on the road to making slab page reassignment work fully) 444 4452003-08-12 (Brad Fitzpatrick) 446 * use TCP_CORK on Linux or TCP_PUSH on BSD 447 * only use TCP_NODELAY when we don't have alternatives 448 4492003-08-10 450 * disable Nagel's Algorithm (TCP_NODELAY) for better performance (avva) 451 4522003-08-10 453 * support multiple levels of verbosity (-vv) 454 4552003-08-10 (Evan Martin) 456 * Makefile.am: debug, optimization, and static flags are controlled 457 by the configure script. 458 * configure.ac: 459 - allow specifying libevent directory with --with-libevent=DIR 460 - check for malloc.h (unavailable on BSDs) 461 - check for socklen_t (unavailable on OSX) 462 * assoc.c, items.c, slabs.c: Remove some unused headers. 463 * memcached.c: allow for nonexistence of malloc.h; #define a POSIX 464 macro to import mlockall flags. 465 4662003-07-29 467 * version 1.1.7 468 * big bug fix: item exptime 0 meant expire immediately, not never 469 * version 1.1.8 470 4712003-07-22 472 * make 'delete' take second arg, of time to refuse new add/replace 473 * set/add/replace/delete can all take abs or delta time (delta can't 474 be larger than a month) 475 4762003-07-21 477 * added doc/protocol.txt 478 4792003-07-01 480 * report CPU usage in stats 481 4822003-06-30 483 * version 1.1.6 484 * fix a number of obscure bugs 485 * more stats reporting 486 4872003-06-10 488 * removing use of Judy; use a hash.
