Split the command processing into 243 separate functions for easier profiling and better readability. 244 Pass key lengths along with the keys in all API functions that 245 need keys, to avoid needing to call strlen() repeatedly. 246 2472006-11-25 248 * Steve Peters <[email protected]>: OpenBSD has a malloc.h, 249 but warns to use stdlib.h instead 250 2512006-11-22 252 * Steven Grimm <[email protected]>: Add support for multithreaded 253 execution.

(intertwined patch, committed all together) 302 <http://lists.danga.com/pipermail/memcached/2006-May/002164.html> 303 or see svn commit logs 304 3052006-04-30 306 * River Tarnell: autoconf work for Solaris 10. Brad: 307 merge and verify it works on Nexenta. 308 3092006-03-04 310 * avva: bucket/generation patch (old, but Brad's just finally 311 committing it) 312 3132006-01-01 314 * Brad Fitzpatrick <[email protected]>: allocate 1 slab per class 315 on start-up, to avoid confusing users with out-of-memory errors 316 later. this is 18 MB of allocation on start, unless max memory 317 allowed with -m is lower, in which case only the smaller slab 318 classes are allocated. 319 3202005-08-09 321 * Elizabeth Mattijsen <[email protected]>: needed a way to flush all 322 memcached backend servers, but not at exactly the same time (to 323 reduce load peaks), I've added some simple functionality to the 324 memcached protocol in the "flush_all" command that allows you to 325 specify a time at which the flush will actually occur (instead of 326 always at the moment the "flush_all" command is received). 327 3282005-05-25 329 * patch from Peter van Dijk <[email protected]> to make 330 stderr unbuffered, for running under daemontools 331 3322005-04-04 333 * patch from Don MacAskill <[email protected]> 'flush_all' doesn't 334 seem to work properly. Basically, if you try to add a key which 335 is present, but expired, the store fails but the old key is no 336 longer expired. 337 338 * release 1.1.12 339 3402005-01-14 341 * Date: Thu, 18 Nov 2004 15:25:59 -0600 342 From: David Phillips <[email protected]> 343 Here is a patch to configure.ac and Makefile.am to put the man page in 344 the correct location. Trying to install the man page from a 345 subdirectory results in the subdirectory being used in the install 346 path (it tries to install to doc/memcached.1). This is the correct 347 thing to do: 348 349 - create a Makefile.am in the doc directory that installs the man page 350 with man_MANS 351 - modify Makefile.am in the base directory to reference the doc 352 directory using SUBDIRS 353 - modify the AC_CONFIG_FILES macro in configure.ac to output the 354 Makefile in doc 355 356 3572005-01-14 358 * pidfile saving support from Lisa Seelye <[email protected]>, sent 359 Jan 13, 2005 360 3612005-01-14 362 * don't delete libevent events that haven't been added (the deltimer) 363 patch from Ted Schundler <[email protected]> 364 3652004-12-10 366 * document -M and -r in manpage (Doug Porter <[email protected]>) 367 3682004-07-22 369 * fix buffer overflow in items.c with 250 byte keys along with 370 other info on the same line going into a 256 byte char[]. 371 thanks to Andrei Nigmatulin <[email protected]> 372 3732004-06-15 374 * immediate deletes weren't being unlinked a few seconds, 375 preventing "add" commands to the same key in that time period. 376 thanks to Michael Alan Dorman <[email protected]> for the 377 bug report and demo script. 378 3792004-04-30 380 * released 1.1.11 381 3822004-04-24 383 * Avva: Add a new command line option: -r , to maximize core file 384 limit. 385 3862004-03-31 387 * Avva: Use getrlimit and setrlimit to set limits for number of 388 simultaneously open file descriptors. Get the current limits and 389 try to raise them if they're not enough for the specified (or the 390 default) setting of max connections. 391 3922004-02-24 393 * Adds a '-M' flag to turn off tossing items from the cache. 394 (Jason Titus <[email protected]>) 395 3962004-02-19 (Evan) 397 * Install manpage on "make install", etc. 398 3992003-12-30 (Brad) 400 * remove static build stuff. interferes with PAM setuid stuff 401 and was only included as a possible fix with the old memory 402 allocator. really shouldn't make a difference. 403 * add Jay Bonci's Debian scripts and manpage 404 * release version 1.1.10 405 4062003-12-01 (Avva) 407 * New command: flush_all, causes all existing items to 408 be invalidated immediately (without deleting them from 409 memory, merely causing memcached to no longer return them). 4102003-10-23 411 * Shift init code around to fix daemon mode on FreeBSD, 412 * and drop root only after creating the server socket (to 413 * allow the use of privileged ports) 414 * version 1.1.10pre 415 4162003-10-09 417 * BSD compile fixes from Ryan T. Dean 418 * version 1.1.9 419 4202003-09-29 421 * ignore SIGPIPE at start instead of crashing in rare cases it 422 comes up. no other code had to be modified, since everything 423 else is already dead-connection-aware. (avva) 424 4252003-09-09 (Avva, Lisa Marie Seelye <[email protected]>) 426 * setuid support 427 4282003-09-05 (Avva) 429 * accept all new connections in the same event (so we work with ET epoll) 430 * mark all items as clsid=0 after slab page reassignment to please future 431 asserts (on the road to making slab page reassignment work fully) 432 4332003-08-12 (Brad Fitzpatrick) 434 * use TCP_CORK on Linux or TCP_PUSH on BSD 435 * only use TCP_NODELAY when we don't have alternatives 436 4372003-08-10 438 * disable Nagel's Algorithm (TCP_NODELAY) for better performance (avva) 439 4402003-08-10 441 * support multiple levels of verbosity (-vv) 442 4432003-08-10 (Evan Martin) 444 * Makefile.am: debug, optimization, and static flags are controlled 445 by the configure script. 446 * configure.ac: 447 - allow specifying libevent directory with --with-libevent=DIR 448 - check for malloc.h (unavailable on BSDs) 449 - check for socklen_t (unavailable on OSX) 450 * assoc.c, items.c, slabs.c: Remove some unused headers. 451 * memcached.c: allow for nonexistence of malloc.h; #define a POSIX 452 macro to import mlockall flags. 453 4542003-07-29 455 * version 1.1.7 456 * big bug fix: item exptime 0 meant expire immediately, not never 457 * version 1.1.8 458 4592003-07-22 460 * make 'delete' take second arg, of time to refuse new add/replace 461 * set/add/replace/delete can all take abs or delta time (delta can't 462 be larger than a month) 463 4642003-07-21 465 * added doc/protocol.txt 466 4672003-07-01 468 * report CPU usage in stats 469 4702003-06-30 471 * version 1.1.6 472 * fix a number of obscure bugs 473 * more stats reporting 474 4752003-06-10 476 * removing use of Judy; use a hash.
