+
+2006-11-26

+
+2006-09-09
+	* release 1.2.0 (along with 1.1.13, which is the more tested branch)
+
+	nobody has run 1.2.0 in production, to my knowledge.  facebook has run

+	  efficiency.  (intertwined patch, committed all together)
+	  <http://lists.danga.com/pipermail/memcached/2006-May/002164.html>
+	  or see svn commit logs
+
+2006-04-30
+	* River Tarnell:  autoconf work for Solaris 10.  Brad:
+	merge and verify it works on Nexenta.
+
+2006-03-04
+	* avva: bucket/generation patch (old, but Brad's just finally
+	committing it)
+
+2006-01-01
+	* Brad Fitzpatrick <brad@danga.com>:  allocate 1 slab per class
+	on start-up, to avoid confusing users with out-of-memory errors
+	later.  this is 18 MB of allocation on start, unless max memory
+	allowed with -m is lower, in which case only the smaller slab
+	classes are allocated.
+
+2005-08-09
+	* Elizabeth Mattijsen <liz@dijkmat.nl>: needed a way to flush all
+	memcached backend servers, but not at exactly the same time (to
+	reduce load peaks), I've added some simple functionality to the
+	memcached protocol in the "flush_all" command that allows you to
+	specify a time at which the flush will actually occur (instead of
+	always at the moment the "flush_all" command is received).
+
+2005-05-25
+	* patch from Peter van Dijk <peter@nextgear.nl> to make
+	  stderr unbuffered, for running under daemontools
+
+2005-04-04
+	* patch from Don MacAskill <don@smugmug.com> 'flush_all' doesn't
+	seem to work properly.  Basically, if you try to add a key which
+	is present, but expired, the store fails but the old key is no
+	longer expired.
+
+	* release 1.1.12
+
+2005-01-14
+	* Date: Thu, 18 Nov 2004 15:25:59 -0600
+	  From: David Phillips <electrum@gmail.com>
+	Here is a patch to configure.ac and Makefile.am to put the man page in
+	the correct location.  Trying to install the man page from a
+	subdirectory results in the subdirectory being used in the install
+	path (it tries to install to doc/memcached.1).  This is the correct
+	thing to  do:
+
+	- create a Makefile.am in the doc directory that installs the man page
+	  with man_MANS
+	- modify Makefile.am in the base directory to reference the doc
+  	  directory using SUBDIRS
+	- modify the AC_CONFIG_FILES macro in configure.ac to output the 
+	  Makefile in doc
+
+	
+2005-01-14
+	* pidfile saving support from Lisa Seelye <lisa@gentoo.org>, sent
+	  Jan 13, 2005
+
+2005-01-14
+	* don't delete libevent events that haven't been added (the deltimer)
+	  patch from Ted Schundler <tschundler@gmail.com>
+
+2004-12-10
+	* document -M and -r in manpage (Doug Porter <dsp@dsp.name>)
+
+2004-07-22
+	* fix buffer overflow in items.c with 250 byte keys along with
+	  other info on the same line going into a 256 byte char[].
+	  thanks to Andrei Nigmatulin <anight@monamour.ru>
+	
+2004-06-15
+	* immediate deletes weren't being unlinked a few seconds,
+	  preventing "add" commands to the same key in that time period.
+	  thanks to Michael Alan Dorman <mdorman@debian.org> for the
+	  bug report and demo script.
+	
+2004-04-30
+	* released 1.1.11
+
+2004-04-24
+	* Avva: Add a new command line option: -r , to maximize core file
+	limit.
+
+2004-03-31
+	* Avva: Use getrlimit and setrlimit to set limits for number of
+	simultaneously open file descriptors. Get the current limits and
+	try to raise them if they're not enough for the specified (or the
+	default) setting of max connections.
+	
+2004-02-24
+	* Adds a '-M' flag to turn off tossing items from the cache.
+	  (Jason Titus <jtitus@postini.com>)
+
+2004-02-19 (Evan)
+	* Install manpage on "make install", etc.
+
+2003-12-30 (Brad)
+	* remove static build stuff.  interferes with PAM setuid stuff

+	  allocator.  really shouldn't make a difference.
+	* add Jay Bonci's Debian scripts and manpage
+	* release version 1.1.10
+
+2003-12-01 (Avva)
+	* New command: flush_all, causes all existing items to
+	  be invalidated immediately (without deleting them from
+	  memory, merely causing memcached to no longer return them).
+2003-10-23
+	* Shift init code around to fix daemon mode on FreeBSD,
+	* and drop root only after creating the server socket (to
+	* allow the use of privileged ports)
+	* version 1.1.10pre
+
+2003-10-09
+	* BSD compile fixes from Ryan T. Dean
+	* version 1.1.9
+	
+2003-09-29

+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about.  Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+
+If using Linux, you need a kernel with epoll.  Sure, libevent will
+work with normal select, but it sucks.
+
+epoll isn't in Linux 2.4 yet, but there's a backport at:
+
+    http://www.xmailserver.org/linux-patches/nio-improve.html
+     
+You want the epoll-lt patch (level-triggered).
+
+If you're using MacOS, you'll want libevent 1.1 or higher to deal with 
+a kqueue bug.
+
+Also, be warned that the -k (mlockall) option to memcached might be
+dangerous when using a large cache.  Just make sure the memcached machines
+don't swap.  memcached does non-blocking network I/O, but not disk.  (it
+should never go to disk, or you've lost the whole point of it)
+
+The memcached website is at:

+
+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+
+If four pairs of (a,b,c) inputs are run through mix(), or through
+mix() in reverse, there are at least 32 bits of the output that
+are sometimes the same for one pair and different for another pair.
+This was tested for:
+* pairs that differed by one bit, by two bits, in any combination
+  of top bits of (a,b,c), or in any combination of bottom bits of
+  (a,b,c).
+* "differ" is defined as +, -, ^, or ~^.  For + and -, I transformed
+  the output delta to a Gray code (a^(a>>1)) so a string of 1's (as
+  is commonly produced by subtraction) look like a single 1-bit
+  difference.
+* the base values were pseudorandom, all zero but one bit set, or
+  all zero plus a counter that starts at zero.
+
+Some k values for my "a-=c; a^=rot(c,k); c+=b;" arrangement that

+used http://burtleburtle.net/bob/hash/avalanche.html to choose
+the operations, constants, and arrangements of the variables.
+
+This does not achieve avalanche.  There are input bits of (a,b,c)
+that fail to affect some output bits of (a,b,c), especially of a.  The
+most thoroughly mixed value is c, but it doesn't really even achieve
+avalanche in c.
+
+This allows some parallelism.  Read-after-writes are good at doubling
+the number of bits affected, so the goal of mixing pulls in the opposite
+direction as the goal of parallelism.  I did what I could.  Rotates
+seem to cost as much as shifts on every machine I could lay my hands
+on, and rotates are much kinder to the top and bottom bits, so I used
+rotates.

+\`configure' configures memcached 1.2.3 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+			  [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+			  [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR           user executables [EPREFIX/bin]
+  --sbindir=DIR          system admin executables [EPREFIX/sbin]
+  --libexecdir=DIR       program executables [EPREFIX/libexec]

+  --libdir=DIR           object code libraries [EPREFIX/lib]
+  --includedir=DIR       C header files [PREFIX/include]
+  --oldincludedir=DIR    C header files for non-gcc [/usr/include]
+  --datarootdir=DIR      read-only arch.-independent data root [PREFIX/share]

+  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
+  --with-libevent=PATH     Specify path to libevent installation
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+	    meantime, this test will reject xlc, which is OK, since
+	    our stdbool.h substitute should suffice.  We also test

+.SH NAME
+memcached \- high-performance memory object caching system
+.SH SYNOPSIS
+.B memcached
+.RI [ options ]
+.br
+.SH DESCRIPTION
+This manual page documents briefly the
+.B memcached
+memory object caching daemon.
+.PP
+.B memcached
+is a flexible memory object caching daemon designed to alleviate database load
+in dynamic web applications by storing objects in memory.  It's based on 
+libevent to scale to any size needed, and is specifically optimized to avoid 
+swapping and always use non-blocking I/O.
+.br
+.SH OPTIONS
+These programs follow the usual GNU command line syntax. A summary of options 
+is included below.
+.TP
+.B \-l <ip_addr>  
+Listen on <ip_addr>; default to INDRR_ANY. This is an important option to 
+consider as there is no other way to secure the installation. Binding to an 
+internal or firewalled network interface is suggested.
+.TP
+.B \-d
+Run memcached as a daemon.
+.TP
+.B \-u <username> 
+Assume the identity of <username> (only when run as root).
+.TP
+.B \-m <num>
+Use <num> MB memory max to use for object storage; the default is 64 megabytes.
+.TP
+.B \-c <num>
+Use <num> max simultaneous connections; the default is 1024.
+.TP
+.B \-k 
+Lock down all paged memory. This is a somewhat dangerous option with large
+caches, so consult the README and memcached homepage for configuration
+suggestions.
+.TP
+.B \-p <num> 
+Listen on TCP port <num>, the default is port 11211.
+.TP
+.B \-U <num> 
+Listen on UDP port <num>, the default is port 11211.
+.TP
+.B \-M
+Disable automatic removal of items from the cache when out of memory.
+Additions will not be possible until adequate space is freed up.
+.TP
+.B \-r
+Raise the core file size limit to the maximum allowable.
+.TP
+.B \-f <factor>
+Use <factor> as the multiplier for computing the sizes of memory chunks that
+items are stored in. A lower value may result in less wasted memory depending
+on the total amount of memory available and the distribution of item sizes.
+The default is 1.25.
+.TP
+.B \-s <size>
+Allocate a minimum of <size> bytes for the item key, value, and flags. The
+default is 48. If you have a lot of small keys and values, you can get a
+significant memory efficiency gain with a lower value. If you use a high
+chunk growth factor (-f option), on the other hand, you may want to increase
+the size to allow a bigger percentage of your items to fit in the most densely
+packed (smallest) chunks.
+.TP
+.B \-h
+Show the version of memcached and a summary of options.
+.TP
+.B \-v
+Be verbose during the event loop; print out errors and warnings.
+.TP
+.B \-vv
+Be even more verbose; same as \-v but also print client commands and 
+responses.
+.TP
+.B \-i
+Print memcached and libevent licenses.
+.TP
+.B \-P <filename>
+Print pidfile to <filename>, only used under -d option.
+.TP
+.B \-t <threads>
+Number of threads to use to process incoming requests. This option is only
+meaningful if memcached was compiled with thread support enabled. It is 
+typically not useful to set this higher than the number of CPU cores on the
+memcached server.
+.TP
+.B \-D <char>
+Use <char> as the delimiter between key prefixes and IDs. This is used for
+per-prefix stats reporting. The default is ":" (colon). If this option is
+specified, stats collection is turned on automatically; if not, then it may
+be turned on by sending the "stats detail on" command to the server.

+
+There's no documentation yet, and it's worth mentioning that this
+subsystem is the most active area of memcached under development at the 
+moment (however, all the changes to it won't modify the way memcached
+presents itself towards clients, they're primarily directed at making
+memcached use memory more efficiently).
+
+Here's a quick recap of what it does now and what is being worked
+on. 
+
+The primary goal of the slabs subsystem in memcached was to eliminate
+memory fragmentation issues totally by using fixed-size memory chunks
+coming from a few predetermined size classes (early versions of 
+memcached relied on malloc()'s handling of fragmentation which proved 
+woefully inadequate for our purposes). For instance, suppose
+we decide at the outset that the list of possible sizes is: 64 bytes,
+128 bytes, 256 bytes, etc. - doubling all the way up to 1Mb. For each
+size class in this list (each possible size) we maintain a list of free
+chunks of this size. Whenever a request comes for a particular size,
+it is rounded up to the closest size class and a free chunk is taken 
+from that size class. In the above example, if you request from the 
+slabs subsystem 100 bytes of memory, you'll actually get a chunk 128
+bytes worth, from the 128-bytes size class. If there are no free chunks
+of the needed size at the moment, there are two ways to get one: 1) free
+an existing chunk in the same size class, using LRU queues to free the 
+least needed objects; 2) get more memory from the system, which we 
+currently always do in _slabs_ of 1Mb each; we malloc() a slab, divide 
+it to chunks of the needed size, and use them.
+
+The tradeoff is between memory fragmentation and memory utilisation. In 
+the scheme we're now using, we have zero fragmentation, but a relatively
+high percentage of memory is wasted. The most efficient way to reduce
+the waste is to use a list of size classes that closely matches (if 
+that's at all possible) common sizes of objects that the clients
+of this particular installation of memcached are likely to store.
+For example, if your installation is going to store hundreds of                                                                  thousands of objects of the size exactly 120 bytes, you'd be much better
+off changing, in the "naive" list of sizes outlined above, the class
+of 128 bytes to something a bit higher (because the overhead of 
+storing an item, while not large, will push those 120-bytes objects over 
+128 bytes of storage internally, and will require using 256 bytes for
+each of them in the naive scheme, forcing you to waste almost 50% of
+memory). Such tinkering with the list of size classes is not currently
+possible with memcached, but enabling it is one of the immediate goals.
+
+Ideally, the slabs subsystem would analyze at runtime the common sizes
+of objects that are being requested, and would be able to modify the
+list of sizes dynamically to improve memory utilisation. This is not
+planned for the immediate future, however. What is planned is the 
+ability to reassign slabs to different classes. Here's what this means. 
+Currently, the total amount of memory allocated for each size class is
+determined by how clients interact with memcached during the initial 
+phase of its execution, when it keeps malloc()'ing more slabs and 
+dividing them into chunks, until it hits the specified memory limit 
+(say, 2Gb, or whatever else was specified). Once it hits the limit, to 
+allocate a new chunk it'll always delete an existing chunk of the same 
+size (using LRU queues), and will never malloc() or free() any memory 
+from/to the system. So if, for example, during those initial few hours 
+of memcached's execution your clients mainly wanted to store very small 
+items, the bulk of memory allocated will be divided to small-sized 
+chunks, and the large size classes will get fewer memory, therefore the 
+life-cycle of large objects you'll store in memcached will henceforth 
+always be much shorter, with this instance of memcached (their LRU 
+queues will be shorter and they'll be pushed out much more often). In 
+general, if your system starts producing a different pattern of common 
+object sizes, the memcached servers will become less efficient, unless 
+you restart them. Slabs reassignment, which is the next feature being 
+worked on, will ensure the server's ability to reclaim a slab (1Mb of 
+memory) from one size  class and put it into another class size, where 
+it's needed more.

+Protocol
+--------
+
+Clients of memcached communicate with server through TCP connections.
+(A UDP interface is also available; details are below under "UDP
+protocol.") A given running memcached server listens on some
+(configurable) port; clients connect to that port, send commands to
+the server, read responses, and eventually close the connection.
+
+There is no need to send any command to end the session. A client may
+just close the connection at any moment it no longer needs it. Note,
+however, that clients are encouraged to cache their connections rather
+than reopen them every time they need to store or retrieve data.  This
+is because memcached is especially designed to work very efficiently
+with a very large number (many hundreds, more than a thousand if
+necessary) of open connections. Caching connections will eliminate the
+overhead associated with establishing a TCP connection (the overhead
+of preparing for a new connection on the server side is insignificant
+compared to this).
+
+There are two kinds of data sent in the memcache protocol: text lines
+and unstructured data.  Text lines are used for commands from clients
+and responses from servers. Unstructured data is sent when a client
+wants to store or retrieve data. The server will transmit back
+unstructured data in exactly the same way it received it, as a byte
+stream. The server doesn't care about byte order issues in
+unstructured data and isn't aware of them. There are no limitations on
+characters that may appear in unstructured data; however, the reader
+of such data (either a client or a server) will always know, from a
+preceding text line, the exact length of the data block being
+transmitted.
+
+Text lines are always terminated by \r\n. Unstructured data is _also_
+terminated by \r\n, even though \r, \n or any other 8-bit characters
+may also appear inside the data. Therefore, when a client retrieves
+data from a server, it must use the length of the data block (which it
+will be provided with) to determine where the data block ends, and not
+the fact that \r\n follows the end of the data block, even though it
+does.
+
+Keys
+----
+
+Data stored by memcached is identified with the help of a key. A key
+is a text string which should uniquely identify the data for clients
+that are interested in storing and retrieving it.  Currently the
+length limit of a key is set at 250 characters (of course, normally
+clients wouldn't need to use such long keys); the key must not include
+control characters or whitespace.
+
+Commands
+--------
+
+There are three types of commands. 
+
+Storage commands (there are three: "set", "add" and "replace") ask the
+server to store some data identified by a key. The client sends a
+command line, and then a data block; after that the client expects one
+line of response, which will indicate success or faulure.
+
+Retrieval commands (there is only one: "get") ask the server to
+retrieve data corresponding to a set of keys (one or more keys in one
+request). The client sends a command line, which includes all the
+requested keys; after that for each item the server finds it sends to
+the client one response line with information about the item, and one
+data block with the item's data; this continues until the server
+finished with the "END" response line.
+
+All other commands don't involve unstructured data. In all of them,
+the client sends one command line, and expects (depending on the
+command) either one line of response, or several lines of response
+ending with "END" on the last line.
+
+A command line always starts with the name of the command, followed by
+parameters (if any) delimited by whitespace. Command names are
+lower-case and are case-sensitive.
+
+Expiration times
+----------------
+
+Some commands involve a client sending some kind of expiration time
+(relative to an item or to an operation requested by the client) to
+the server. In all such cases, the actual value sent may either be
+Unix time (number of seconds since January 1, 1970, as a 32-bit
+value), or a number of seconds starting from current time. In the
+latter case, this number of seconds may not exceed 60*60*24*30 (number
+of seconds in 30 days); if the number sent by a client is larger than
+that, the server will consider it to be real Unix time value rather
+than an offset from current time.
+
+
+Error strings
+-------------
+
+Each command sent by a client may be answered with an error string
+from the server. These error strings come in three types:
+
+- "ERROR\r\n" 
+
+  means the client sent a nonexistent command name.
+
+- "CLIENT_ERROR <error>\r\n"
+
+  means some sort of client error in the input line, i.e. the input
+  doesn't conform to the protocol in some way. <error> is a
+  human-readable error string.
+
+- "SERVER_ERROR <error>\r\n"
+
+  means some sort of server error prevents the server from carrying
+  out the command. <error> is a human-readable error string. In cases
+  of severe server errors, which make it impossible to continue
+  serving the client (this shouldn't normally happen), the server will
+  close the connection after sending the error line. This is the only
+  case in which the server closes a connection to a client.
+
+
+In the descriptions of individual commands below, these error lines
+are not again specifically mentioned, but clients must allow for their
+possibility.
+
+
+Storage commands
+----------------
+
+First, the client sends a command line which looks like this:
+
+<command name> <key> <flags> <exptime> <bytes>\r\n
+
+- <command name> is "set", "add" or "replace"
+
+  "set" means "store this data".  
+
+  "add" means "store this data, but only if the server *doesn't* already
+  hold data for this key".  
+
+  "replace" means "store this data, but only if the server *does*
+  already hold data for this key".
+
+- <key> is the key under which the client asks to store the data
+
+- <flags> is an arbitrary 16-bit unsigned integer (written out in
+  decimal) that the server stores along with the data and sends back
+  when the item is retrieved. Clients may use this as a bit field to
+  store data-specific information; this field is opaque to the server.
+  Note that in memcached 1.2.1 and higher, flags may be 32-bits, instead
+  of 16, but you might want to restrict yourself to 16 bits for
+  compatibility with older versions.
+
+- <exptime> is expiration time. If it's 0, the item never expires
+  (although it may be deleted from the cache to make place for other
+  items). If it's non-zero (either Unix time or offset in seconds from
+  current time), it is guaranteed that clients will not be able to
+  retrieve this item after the expiration time arrives (measured by
+  server time).  
+
+- <bytes> is the number of bytes in the data block to follow, *not*
+  including the delimiting \r\n. <bytes> may be zero (in which case
+  it's followed by an empty data block).
+
+After this line, the client sends the data block:
+
+<data block>\r\n
+
+- <data block> is a chunk of arbitrary 8-bit data of length <bytes>
+  from the previous line.
+
+After sending the command line and the data blockm the client awaits
+the reply, which may be:
+
+- "STORED\r\n", to indicate success.
+
+- "NOT_STORED\r\n" to indicate the data was not stored, but not
+because of an error. This normally means that either that the
+condition for an "add" or a "replace" command wasn't met, or that the
+item is in a delete queue (see the "delete" command below).
+
+
+Retrieval command:
+------------------
+
+The retrieval command looks like this:
+
+get <key>*\r\n
+
+- <key>* means one or more key strings separated by whitespace.
+
+After this command, the client expects zero or more items, each of
+which is received as a text line followed by a data block. After all
+the items have been transmitted, the server sends the string
+
+"END\r\n"
+
+to indicate the end of response.
+
+Each item sent by the server looks like this:
+
+VALUE <key> <flags> <bytes>\r\n
+<data block>\r\n
+
+- <key> is the key for the item being sent
+
+- <flags> is the flags value set by the storage command
+
+- <bytes> is the length of the data block to follow, *not* including
+  its delimiting \r\n
+
+- <data block> is the data for this item.
+
+If some of the keys appearing in a retrieval request are not sent back
+by the server in the item list this means that the server does not
+hold items with such keys (because they were never stored, or stored
+but deleted to make space for more items, or expired, or explicitly
+deleted by a client).
+
+
+
+Deletion
+--------
+
+The command "delete" allows for explicit deletion of items:
+
+delete <key> <time>\r\n
+
+- <key> is the key of the item the client wishes the server to delete
+
+- <time> is the amount of time in seconds (or Unix time until which)
+  the client wishes the server to refuse "add" and "replace" commands
+  with this key. For this amount of item, the item is put into a
+  delete queue, which means that it won't possible to retrieve it by
+  the "get" command, but "add" and "replace" command with this key
+  will also fail (the "set" command will succeed, however). After the
+  time passes, the item is finally deleted from server memory.
+
+  The parameter <time> is optional, and, if absent, defaults to 0
+  (which means that the item will be deleted immediately and further
+  storage commands with this key will succeed).
+
+The response line to this command can be one of:
+
+- "DELETED\r\n" to indicate success
+
+- "NOT_FOUND\r\n" to indicate that the item with this key was not
+  found.
+
+See the "flush_all" command below for immediate invalidation
+of all existing items.
+
+
+Increment/Decrement
+-------------------
+
+Commands "incr" and "decr" are used to change data for some item
+in-place, incrementing or decrementing it. The data for the item is
+treated as decimal representation of a 32-bit unsigned integer. If the
+current data value does not conform to such a representation, the
+commands behave as if the value were 0. Also, the item must already
+exist for incr/decr to work; these commands won't pretend that a
+non-existent key exists with value 0; instead, they will fail.
+
+The client sends the command line:
+
+incr <key> <value>\r\n
+
+or
+
+decr <key> <value>\r\n
+
+- <key> is the key of the item the client wishes to change
+
+- <value> is the amount by which the client wants to increase/decrease
+the item. It is a decimal representation of a 32-bit unsigned integer.
+
+The response will be one of:
+
+- "NOT_FOUND\r\n" to indicate the item with this value was not found
+
+- <value>\r\n , where <value> is the new value of the item's data,
+  after the increment/decrement operation was carried out.
+
+Note that underflow in the "decr" command is caught: if a client tries
+to decrease the value below 0, the new value will be 0. Overflow in
+the "incr" command is not checked.
+
+Note also that decrementing a number such that it loses length isn't
+guaranteed to decrement its returned length.  The number MAY be
+space-padded at the end, but this is purely an implementation
+optimization, so you also shouldn't rely on that.
+
+Statistics
+----------
+
+The command "stats" is used to query the server about statistics it
+maintains and other internal data. It has two forms. Without
+arguments:
+
+stats\r\n
+
+it causes the server to output general-purpose statistics and
+settings, documented below.  In the other form it has some arguments:
+
+stats <args>\r\n
+
+Depending on <args>, various internal data is sent by the server. The
+kinds of arguments and the data sent are not documented in this vesion
+of the protocol, and are subject to change for the convenience of
+memcache developers.
+
+
+General-purpose statistics
+--------------------------
+
+Upon receiving the "stats" command without arguments, the server sents
+a number of lines which look like this:
+
+STAT <name> <value>\r\n
+
+The server terminates this list with the line
+
+END\r\n
+
+In each line of statistics, <name> is the name of this statistic, and
+<value> is the data.  The following is the list of all names sent in
+response to the "stats" command, together with the type of the value
+sent for this name, and the meaning of the value.
+
+In the type column below, "32u" means a 32-bit unsigned integer, "64u"
+means a 64-bit unsigner integer. '32u:32u' means two 32-but unsigned
+integers separated by a colon.
+

+                           use for storage. 
+
+
+
+Other commands
+--------------
+
+"flush_all" is a command with an optional numeric argument. It always
+succeeds, and the server sends "OK\r\n" in response. Its effect is to
+invalidate all existing items immediately (by default) or after the
+expiration specified.  After invalidation none of the items will be returned
+in response to a retrieval command (unless it's stored again under the
+same key *after* flush_all has invalidated the items). flush_all doesn't
+actually free all the memory taken up by existing items; that will
+happen gradually as new items are stored. The most precise definition
+of what flush_all does is the following: it causes all items whose
+update time is earlier than the time at which flush_all was set to be
+executed to be ignored for retrieval purposes.
+
+The intent of flush_all with a delay, was that in a setting where you
+have a pool of memcached servers, and you need to flush all content,
+you have the option of not resetting all memcached servers at the
+same time (which could e.g. cause a spike in database load with all
+clients suddenly needing to recreate content that would otherwise
+have been found in the memcached daemon).
+
+The delay option allows you to have them reset in e.g. 10 second
+intervals (by passing 0 to the first, 10 to the second, 20 to the
+third, etc. etc.).
+
+
+"version" is a command with no arguments:
+
+version\r\n
+
+In response, the server sends
+
+"VERSION <version>\r\n", where <version> is the version string for the
+server.
+
+"verbosity" is a command with a numeric argument. It always                                                  
+succeeds, and the server sends "OK\r\n" in response. Its effect is to                                        
+set the verbosity level of the logging output.                                                               
+
+"quit" is a command with no arguments:
+
+quit\r\n
+
+Upon receiving this command, the server closes the
+connection. However, the client may also simply close the connection
+when it no longer needs it, without issuing this command.
+
+
+UDP protocol
+------------
+
+For very large installations where the number of clients is high enough
+that the number of TCP connections causes scaling difficulties, there is
+also a UDP-based interface. The UDP interface does not provide guaranteed
+delivery, so should only be used for operations that aren't required to
+succeed; typically it is used for "get" requests where a missing or
+incomplete response can simply be treated as a cache miss.
+
+Each UDP datagram contains a simple frame header, followed by data in the
+same format as the TCP protocol described above. In the current
+implementation, requests must be contained in a single UDP datagram, but
+responses may span several datagrams. (The only common requests that would
+span multiple datagrams are huge multi-key "get" requests and "set"
+requests, both of which are more suitable to TCP transport for reliability
+reasons anyway.)
+
+The frame header is 8 bytes long, as follows (all values are 16-bit integers
+in network byte order, high byte first):
+
+0-1 Request ID
+2-3 Sequence number
+4-5 Total number of datagrams in this message
+6-7 Reserved for future use; must be 0
+
+The request ID is supplied by the client. Typically it will be a
+monotonically increasing value starting from a random seed, but the client
+is free to use whatever request IDs it likes. The server's response will
+contain the same ID as the incoming request. The client uses the request ID
+to differentiate between responses to outstanding requests if there are
+several pending from the same server; any datagrams with an unknown request
+ID are probably delayed responses to an earlier request and should be
+discarded.
+
+The sequence number ranges from 0 to n-1, where n is the total number of
+datagrams in the message. The client should concatenate the payloads of the
+datagrams for a given response in sequence number order; the resulting byte
+stream will contain a complete response in the same format as the TCP
+protocol (including terminating \r\n sequences).

+Multithreading support in memcached
+
+OVERVIEW
+
+By default, memcached is compiled as a single-threaded application. This is
+the most CPU-efficient mode of operation, and it is appropriate for memcached
+instances running on single-processor servers or whose request volume is
+low enough that available CPU power is not a bottleneck.
+
+More heavily-used memcached instances can benefit from multithreaded mode.
+To enable it, use the "--enable-threads" option to the configure script:
+
+./configure --enable-threads
+
+You must have the POSIX thread functions (pthread_*) on your system in order
+to use memcached's multithreaded mode.
+
+Once you have a thread-capable memcached executable, you can control the
+number of threads using the "-t" option; the default is 4. On a machine
+that's dedicated to memcached, you will typically want one thread per
+processor core. Due to memcached's nonblocking architecture, there is no
+real advantage to using more threads than the number of CPUs on the machine;
+doing so will increase lock contention and is likely to degrade performance.
+
+
+INTERNALS
+
+The threading support is mostly implemented as a series of wrapper functions
+that protect calls to underlying code with one of a small number of locks.
+In single-threaded mode, the wrappers are replaced with direct invocations
+of the target code using #define; that is done in memcached.h. This approach
+allows memcached to be compiled in either single- or multi-threaded mode.
+
+Each thread has its own instance of libevent ("base" in libevent terminology).
+The only direct interaction between threads is for new connections. One of
+the threads handles the TCP listen socket; each new connection is passed to
+a different thread on a round-robin basis. After that, each thread operates
+on its set of connections as if it were running in single-threaded mode,
+using libevent to manage nonblocking I/O as usual.
+
+UDP requests are a bit different, since there is only one UDP socket that's
+shared by all clients. The UDP socket is monitored by all of the threads.
+When a datagram comes in, all the threads that aren't already processing
+another request will receive "socket readable" callbacks from libevent.
+Only one thread will successfully read the request; the others will go back
+to sleep or, in the case of a very busy server, will read whatever other
+UDP requests are waiting in the socket buffer. Note that in the case of
+moderately busy servers, this results in increased CPU consumption since
+threads will constantly wake up and find no input waiting for them. But
+short of much more major surgery on the I/O code, this is not easy to avoid.
+
+
+TO DO
+
+The locking is currently very coarse-grained.  There is, for example, one
+lock that protects all the calls to the hashtable-related functions. Since
+memcached spends much of its CPU time on command parsing and response
+assembly, rather than managing the hashtable per se, this is not a huge
+bottleneck for small numbers of processors. However, the locking will likely
+have to be refined in the event that memcached needs to run well on
+massively-parallel machines.
+
+One cheap optimization to reduce contention on that lock: move the hash value
+computation so it occurs before the lock is obtained whenever possible.
+Right now the hash is performed at the lowest levels of the functions in
+assoc.c. If instead it was computed in memcached.c, then passed along with
+the key and length into the items.c code and down into assoc.c, that would
+reduce the amount of time each thread needs to keep the hashtable lock held.
