Split the command processing into 259 separate functions for easier profiling and better readability. 260 Pass key lengths along with the keys in all API functions that 261 need keys, to avoid needing to call strlen() repeatedly. 262 2632006-11-25 264 * Steve Peters <[email protected]>: OpenBSD has a malloc.h, 265 but warns to use stdlib.h instead 266 2672006-11-22 268 * Steven Grimm <[email protected]>: Add support for multithreaded 269 execution.

(intertwined patch, committed all together) 318 <http://lists.danga.com/pipermail/memcached/2006-May/002164.html> 319 or see svn commit logs 320 3212006-04-30 322 * River Tarnell: autoconf work for Solaris 10. Brad: 323 merge and verify it works on Nexenta. 324 3252006-03-04 326 * avva: bucket/generation patch (old, but Brad's just finally 327 committing it) 328 3292006-01-01 330 * Brad Fitzpatrick <[email protected]>: allocate 1 slab per class 331 on start-up, to avoid confusing users with out-of-memory errors 332 later. this is 18 MB of allocation on start, unless max memory 333 allowed with -m is lower, in which case only the smaller slab 334 classes are allocated. 335 3362005-08-09 337 * Elizabeth Mattijsen <[email protected]>: needed a way to flush all 338 memcached backend servers, but not at exactly the same time (to 339 reduce load peaks), I've added some simple functionality to the 340 memcached protocol in the "flush_all" command that allows you to 341 specify a time at which the flush will actually occur (instead of 342 always at the moment the "flush_all" command is received). 343 3442005-05-25 345 * patch from Peter van Dijk <[email protected]> to make 346 stderr unbuffered, for running under daemontools 347 3482005-04-04 349 * patch from Don MacAskill <[email protected]> 'flush_all' doesn't 350 seem to work properly. Basically, if you try to add a key which 351 is present, but expired, the store fails but the old key is no 352 longer expired. 353 354 * release 1.1.12 355 3562005-01-14 357 * Date: Thu, 18 Nov 2004 15:25:59 -0600 358 From: David Phillips <[email protected]> 359 Here is a patch to configure.ac and Makefile.am to put the man page in 360 the correct location. Trying to install the man page from a 361 subdirectory results in the subdirectory being used in the install 362 path (it tries to install to doc/memcached.1). This is the correct 363 thing to do: 364 365 - create a Makefile.am in the doc directory that installs the man page 366 with man_MANS 367 - modify Makefile.am in the base directory to reference the doc 368 directory using SUBDIRS 369 - modify the AC_CONFIG_FILES macro in configure.ac to output the 370 Makefile in doc 371 372 3732005-01-14 374 * pidfile saving support from Lisa Seelye <[email protected]>, sent 375 Jan 13, 2005 376 3772005-01-14 378 * don't delete libevent events that haven't been added (the deltimer) 379 patch from Ted Schundler <[email protected]> 380 3812004-12-10 382 * document -M and -r in manpage (Doug Porter <[email protected]>) 383 3842004-07-22 385 * fix buffer overflow in items.c with 250 byte keys along with 386 other info on the same line going into a 256 byte char[]. 387 thanks to Andrei Nigmatulin <[email protected]> 388 3892004-06-15 390 * immediate deletes weren't being unlinked a few seconds, 391 preventing "add" commands to the same key in that time period. 392 thanks to Michael Alan Dorman <[email protected]> for the 393 bug report and demo script. 394 3952004-04-30 396 * released 1.1.11 397 3982004-04-24 399 * Avva: Add a new command line option: -r , to maximize core file 400 limit. 401 4022004-03-31 403 * Avva: Use getrlimit and setrlimit to set limits for number of 404 simultaneously open file descriptors. Get the current limits and 405 try to raise them if they're not enough for the specified (or the 406 default) setting of max connections. 407 4082004-02-24 409 * Adds a '-M' flag to turn off tossing items from the cache. 410 (Jason Titus <[email protected]>) 411 4122004-02-19 (Evan) 413 * Install manpage on "make install", etc. 414 4152003-12-30 (Brad) 416 * remove static build stuff. interferes with PAM setuid stuff 417 and was only included as a possible fix with the old memory 418 allocator. really shouldn't make a difference. 419 * add Jay Bonci's Debian scripts and manpage 420 * release version 1.1.10 421 4222003-12-01 (Avva) 423 * New command: flush_all, causes all existing items to 424 be invalidated immediately (without deleting them from 425 memory, merely causing memcached to no longer return them). 4262003-10-23 427 * Shift init code around to fix daemon mode on FreeBSD, 428 * and drop root only after creating the server socket (to 429 * allow the use of privileged ports) 430 * version 1.1.10pre 431 4322003-10-09 433 * BSD compile fixes from Ryan T. Dean 434 * version 1.1.9 435 4362003-09-29 437 * ignore SIGPIPE at start instead of crashing in rare cases it 438 comes up. no other code had to be modified, since everything 439 else is already dead-connection-aware. (avva) 440 4412003-09-09 (Avva, Lisa Marie Seelye <[email protected]>) 442 * setuid support 443 4442003-09-05 (Avva) 445 * accept all new connections in the same event (so we work with ET epoll) 446 * mark all items as clsid=0 after slab page reassignment to please future 447 asserts (on the road to making slab page reassignment work fully) 448 4492003-08-12 (Brad Fitzpatrick) 450 * use TCP_CORK on Linux or TCP_PUSH on BSD 451 * only use TCP_NODELAY when we don't have alternatives 452 4532003-08-10 454 * disable Nagel's Algorithm (TCP_NODELAY) for better performance (avva) 455 4562003-08-10 457 * support multiple levels of verbosity (-vv) 458 4592003-08-10 (Evan Martin) 460 * Makefile.am: debug, optimization, and static flags are controlled 461 by the configure script. 462 * configure.ac: 463 - allow specifying libevent directory with --with-libevent=DIR 464 - check for malloc.h (unavailable on BSDs) 465 - check for socklen_t (unavailable on OSX) 466 * assoc.c, items.c, slabs.c: Remove some unused headers. 467 * memcached.c: allow for nonexistence of malloc.h; #define a POSIX 468 macro to import mlockall flags. 469 4702003-07-29 471 * version 1.1.7 472 * big bug fix: item exptime 0 meant expire immediately, not never 473 * version 1.1.8 474 4752003-07-22 476 * make 'delete' take second arg, of time to refuse new add/replace 477 * set/add/replace/delete can all take abs or delta time (delta can't 478 be larger than a month) 479 4802003-07-21 481 * added doc/protocol.txt 482 4832003-07-01 484 * report CPU usage in stats 485 4862003-06-30 487 * version 1.1.6 488 * fix a number of obscure bugs 489 * more stats reporting 490 4912003-06-10 492 * removing use of Judy; use a hash.
