| 3 | * Item stats commands weren't thread-safe; wrap them with locks |
|---|
| 4 | when compiled in multithreaded mode. |
|---|
| 5 | * The "stats items" command now works again; it broke with the |
|---|
| 6 | introduction of the powers-of-N chunk size change. |

|---|
| 93 | |
|---|
| 94 | 2007-03-05 Paul Lindner <lindner@inuus.com> |
|---|
| 95 | * Fix a number of places where (s)printf calls were using unsigned |
|---|
| 96 | or signed formats that did not match their arguments. |
|---|
| 97 | |
|---|
| 98 | * Add support for stdbool.h and stdint.h to use the bool and |
|---|
| 99 | uint8_t types. |
|---|
| 100 | |
|---|
| 101 | * Major refactoring - move API calls for assoc/items/slabs to |
|---|
| 102 | their own individual header files. Add apropriate const and |
|---|
| 103 | static declarations as appropriate. |
|---|
| 104 | |
|---|
| 105 | * Avoid type-punning. Do a more efficient realloc inside the |
|---|
| 106 | conn_shrink routine. |
|---|
| 107 | |
|---|
| 108 | * Fix overflow bug where uninitialized access to slabclass caused |
|---|
| 109 | size-0 mallocs during slab preallocation. |
|---|
| 110 | |
|---|
| 111 | * Use EXIT_SUCCESS/EXIT_FAILURE constants. |
|---|
| 112 | |
|---|
| 113 | * Convert some sprintf calls to snprintf to protect against |
|---|
| 114 | buffer overflows. |
|---|
| 115 | |
|---|
| 116 | * Explicitly compare against NULL or zero in many places. |
|---|
| 117 | |
|---|
| 118 | 2007-03-05 |
|---|
| 119 | * Steven Grimm <sgrimm@facebook.com>: Per-object-type stats collection |
|---|
| 120 | support. Specify the object type delimiter with the -D command line |
|---|
| 121 | option. Turn stats gathering on and off with "stats detail on" and |
|---|
| 122 | "stats detail off". Dump the per-object-type details with |
|---|
| 123 | "stats detail dump". |
|---|

|---|
| 130 | * fix expirations of items set with absolute expiration times in |
|---|
| 131 | the past, before the server's start time. bug was introduced in |
|---|
| 132 | 1.2.0 with rel_time_t. Thanks to Adam Dixon |
|---|

| 136 | * Steven Grimm <sgrimm@facebook.com>: Performance improvements: |
|---|
| 137 | |
|---|
| 138 | Dynamic sizing of hashtable to reduce collisions on very large |
|---|
| 139 | caches and conserve memory on small caches. |
|---|
| 140 | |
|---|
| 141 | Only reposition items in the LRU queue once a minute, to reduce |
|---|
| 142 | overhead of accessing extremely frequently-used items. |
|---|
| 143 | |
|---|
| 144 | Stop listening for new connections until an existing one closes |
|---|
| 145 | if we run out of available file descriptors. |
|---|
| 146 | |
|---|
| 147 | Command parser refactoring: Add a single-pass tokenizer to cut |
|---|
| 148 | down on string scanning. Split the command processing into |
|---|
| 149 | separate functions for easier profiling and better readability. |
|---|
| 150 | Pass key lengths along with the keys in all API functions that |
|---|
| 151 | need keys, to avoid needing to call strlen() repeatedly. |
|---|
| 152 | |

|---|
| 156 | |
|---|
| 157 | 2006-11-22 |
|---|
| 158 | * Steven Grimm <sgrimm@facebook.com>: Add support for multithreaded |

| 179 | * release 1.2.0 (along with 1.1.13, which is the more tested branch) |
|---|
| 180 | |
|---|
| 181 | nobody has run 1.2.0 in production, to my knowledge. facebook has run |
|---|
| 182 | their pre-merge-with-trunk version, but bugs were discovered (and fixed) |
|---|
| 183 | after the merge. there might be more. you've been warned. :) |
|---|
| 184 | |
|---|
| 185 | 2006-09-04 |

| 188 | 2006-09-03 |
|---|
| 189 | * test suite and lot of expiration, delete, flush_all, etc corner |

|---|
| 220 | * Brad Fitzpatrick <brad@danga.com>: allocate 1 slab per class |
|---|
| 221 | on start-up, to avoid confusing users with out-of-memory errors |
|---|
| 222 | later. this is 18 MB of allocation on start, unless max memory |
|---|
| 223 | allowed with -m is lower, in which case only the smaller slab |
|---|
| 224 | classes are allocated. |
|---|
| 225 | |
|---|
| 226 | 2005-08-09 |
|---|
| 227 | * Elizabeth Mattijsen <liz@dijkmat.nl>: needed a way to flush all |
|---|
| 228 | memcached backend servers, but not at exactly the same time (to |
|---|
| 229 | reduce load peaks), I've added some simple functionality to the |
|---|
| 230 | memcached protocol in the "flush_all" command that allows you to |
|---|
| 231 | specify a time at which the flush will actually occur (instead of |
|---|
| 232 | always at the moment the "flush_all" command is received). |
|---|
| 233 | |
|---|
| 234 | 2005-05-25 |
|---|
| 235 | * patch from Peter van Dijk <peter@nextgear.nl> to make |
|---|
| 236 | stderr unbuffered, for running under daemontools |
|---|
| 237 | |
|---|
| 238 | 2005-04-04 |
|---|
| 239 | * patch from Don MacAskill <don@smugmug.com> 'flush_all' doesn't |
|---|
| 240 | seem to work properly. Basically, if you try to add a key which |
|---|
| 241 | is present, but expired, the store fails but the old key is no |
|---|
| 242 | longer expired. |
|---|
| 243 | |
|---|
| 244 | * release 1.1.12 |
|---|
| 245 | |

| 247 | * Date: Thu, 18 Nov 2004 15:25:59 -0600 |
|---|
| 248 | From: David Phillips <electrum@gmail.com> |
|---|
| 249 | Here is a patch to configure.ac and Makefile.am to put the man page in |
|---|
| 250 | the correct location. Trying to install the man page from a |
|---|
| 251 | subdirectory results in the subdirectory being used in the install |
|---|
| 252 | path (it tries to install to doc/memcached.1). This is the correct |
|---|
| 253 | thing to do: |
|---|
| 254 | |
|---|
| 255 | - create a Makefile.am in the doc directory that installs the man page |
|---|
| 256 | with man_MANS |
|---|
| 257 | - modify Makefile.am in the base directory to reference the doc |
|---|
| 258 | directory using SUBDIRS |
|---|
| 259 | - modify the AC_CONFIG_FILES macro in configure.ac to output the |
|---|
| 260 | Makefile in doc |
|---|
| 261 | |
|---|
| 262 | |
|---|
| 263 | 2005-01-14 |
|---|
| 264 | * pidfile saving support from Lisa Seelye <lisa@gentoo.org>, sent |
|---|
| 265 | Jan 13, 2005 |
|---|
| 266 | |
|---|
| 267 | 2005-01-14 |
|---|
| 268 | * don't delete libevent events that haven't been added (the deltimer) |
|---|
| 269 | patch from Ted Schundler <tschundler@gmail.com> |
|---|
| 270 | |
|---|
| 271 | 2004-12-10 |
|---|
| 272 | * document -M and -r in manpage (Doug Porter <dsp@dsp.name>) |
|---|
| 273 | |
|---|
| 274 | 2004-07-22 |
|---|
| 275 | * fix buffer overflow in items.c with 250 byte keys along with |
|---|
| 276 | other info on the same line going into a 256 byte char[]. |
|---|
| 277 | thanks to Andrei Nigmatulin <anight@monamour.ru> |
|---|
| 278 | |
|---|
| 279 | 2004-06-15 |
|---|
| 280 | * immediate deletes weren't being unlinked a few seconds, |
|---|
| 281 | preventing "add" commands to the same key in that time period. |
|---|
| 282 | thanks to Michael Alan Dorman <mdorman@debian.org> for the |
|---|
| 283 | bug report and demo script. |
|---|
| 284 | |
|---|
| 285 | 2004-04-30 |
|---|
| 286 | * released 1.1.11 |
|---|
| 287 | |
|---|
| 288 | 2004-04-24 |
|---|
| 289 | * Avva: Add a new command line option: -r , to maximize core file |
|---|
| 290 | limit. |
|---|
| 291 | |
|---|
| 292 | 2004-03-31 |
|---|
| 293 | * Avva: Use getrlimit and setrlimit to set limits for number of |
|---|
| 294 | simultaneously open file descriptors. Get the current limits and |
|---|
| 295 | try to raise them if they're not enough for the specified (or the |
|---|
| 296 | default) setting of max connections. |
|---|
| 297 | |
|---|
| 298 | 2004-02-24 |
|---|
| 299 | * Adds a '-M' flag to turn off tossing items from the cache. |
|---|
| 300 | (Jason Titus <jtitus@postini.com>) |
|---|
| 301 | |
|---|
| 302 | 2004-02-19 (Evan) |
|---|
| 303 | * Install manpage on "make install", etc. |
|---|
| 304 | |
|---|
| 305 | 2003-12-30 (Brad) |
|---|
| 306 | * remove static build stuff. interferes with PAM setuid stuff |
|---|
| 307 | and was only included as a possible fix with the old memory |
|---|
| 308 | allocator. really shouldn't make a difference. |
|---|
| 309 | * add Jay Bonci's Debian scripts and manpage |
|---|
| 310 | * release version 1.1.10 |
|---|
| 311 | |
|---|
| 312 | 2003-12-01 (Avva) |
|---|
| 313 | * New command: flush_all, causes all existing items to |
|---|
| 314 | be invalidated immediately (without deleting them from |
|---|
| 315 | memory, merely causing memcached to no longer return them). |
|---|
| 316 | 2003-10-23 |
|---|
| 317 | * Shift init code around to fix daemon mode on FreeBSD, |
|---|
| 318 | * and drop root only after creating the server socket (to |
|---|
| 319 | * allow the use of privileged ports) |
|---|
| 320 | * version 1.1.10pre |
|---|
| 321 | |
|---|
| 322 | 2003-10-09 |
|---|
| 323 | * BSD compile fixes from Ryan T. Dean |
|---|
| 324 | * version 1.1.9 |
|---|
| 325 | |
|---|
| 326 | 2003-09-29 |
|---|
| 327 | * ignore SIGPIPE at start instead of crashing in rare cases it |
|---|
| 328 | comes up. no other code had to be modified, since everything |
|---|
| 329 | else is already dead-connection-aware. (avva) |
|---|
| 330 | |
|---|
| 331 | 2003-09-09 (Avva, Lisa Marie Seelye <lisa@gentoo.org>) |
|---|
| 332 | * setuid support |
|---|
| 333 | |
|---|
| 334 | 2003-09-05 (Avva) |
|---|
| 335 | * accept all new connections in the same event (so we work with ET epoll) |
|---|
| 336 | * mark all items as clsid=0 after slab page reassignment to please future |
|---|
| 337 | asserts (on the road to making slab page reassignment work fully) |
|---|
| 338 | |
|---|
| 339 | 2003-08-12 (Brad Fitzpatrick) |
|---|
| 340 | * use TCP_CORK on Linux or TCP_PUSH on BSD |
|---|
| 341 | * only use TCP_NODELAY when we don't have alternatives |
|---|
| 342 | |
|---|
| 343 | 2003-08-10 |
|---|
| 344 | * disable Nagel's Algorithm (TCP_NODELAY) for better performance (avva) |
|---|
| 345 | |
|---|
| 346 | 2003-08-10 |
|---|
| 347 | * support multiple levels of verbosity (-vv) |
|---|
| 348 | |
|---|
| 349 | 2003-08-10 (Evan Martin) |
|---|
| 350 | * Makefile.am: debug, optimization, and static flags are controlled |
|---|
| 351 | by the configure script. |
|---|
| 352 | * configure.ac: |
|---|
| 353 | - allow specifying libevent directory with --with-libevent=DIR |
|---|
| 354 | - check for malloc.h (unavailable on BSDs) |
|---|
| 355 | - check for socklen_t (unavailable on OSX) |
|---|
| 356 | * assoc.c, items.c, slabs.c: Remove some unused headers. |
|---|
| 357 | * memcached.c: allow for nonexistence of malloc.h; #define a POSIX |
|---|
| 358 | macro to import mlockall flags. |
|---|
| 359 | |
|---|
| 360 | 2003-07-29 |
|---|
| 361 | * version 1.1.7 |
|---|
| 362 | * big bug fix: item exptime 0 meant expire immediately, not never |
|---|
| 363 | * version 1.1.8 |
|---|
| 364 | |
|---|
