MariaDB and MySQL have identical install methods. In this document we
describe how to install MariaDB; However all documentation at www.mysql.com
also applies.
You can find information about how to install binary distributions at
http://dev.mysql.com/doc/refman/5.1/en/quick-standard-installation.html
2.2. Installing MariaDB from Generic Binaries on Unix/Linux
The MySQL Reference Manual is also available in various formats on
http://dev.mysql.com/doc; if you're interested in the DocBook XML
sources go to http://svn.mysql.com.
This section covers the installation of MariaDB binary distributions
that are provided for various platforms in the form of compressed
tar files (files with a .tar.gz extension).
MariaDB tar file binary distributions have names of the form
mariadb-VERSION-OS.tar.gz, where VERSION is a number (for example,
5.1.39), and OS indicates the type of operating system for which
the distribution is intended (for example, pc-linux-i686).
You need the following tools to install a MariaDB tar file binary
distribution:
* GNU gunzip to uncompress the distribution.
* A reasonable tar to unpack the distribution. GNU tar is known
to work. Some operating systems come with a preinstalled
version of tar that is known to have problems. For example,
the tar provided with early versions of Mac OS X, SunOS 4.x,
Solaris 8, Solaris 9, Solaris 10 and OpenSolaris, and HP-UX
are known to have problems with long file names. On Mac OS X,
you can use the preinstalled gnutar program. On Solaris 10 and
OpenSolaris you can use the preinstalled gtar. On other
systems with a deficient tar, you should install GNU tar
first.
If you run into problems and need to file a bug report,
please report them to: http://bugs.launchpad.net/maria
See the instructions in Section 1.6, "How to Report Bugs or Problems."
The basic commands that you must execute to install and use a
MariaDB binary distribution are:
shell> groupadd mysql
shell> useradd -g mysql mysql
shell> cd /usr/local
shell> gunzip < /path/to/mysql-VERSION-OS.tar.gz | tar xvf -
shell> ln -s full-path-to-mysql-VERSION-OS mysql
shell> cd mysql
shell> chown -R mysql .
shell> chgrp -R mysql .
shell> scripts/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql data
shell> bin/mysqld_safe --user=mysql &
Note
This procedure does not set up any passwords for MariaDB accounts.
After following the procedure, proceed to Section 2.13,
"Post-Installation Setup and Testing."
A more detailed version of the preceding description for
installing a binary distribution follows:
1. Add a login user and group for mysqld to run as:
shell> groupadd mysql
shell> useradd -g mysql mysql
These commands add the mysql group and the mysql user. The
syntax for useradd and groupadd may differ slightly on
different versions of Unix, or they may have different names
such as adduser and addgroup.
You might want to call the user and group something else
instead of mysql. If so, substitute the appropriate name in
the following steps.
2. Pick the directory under which you want to unpack the
distribution and change location into it. In the following
example, we unpack the distribution under /usr/local. (The
instructions, therefore, assume that you have permission to
create files and directories in /usr/local. If that directory
is protected, you must perform the installation as root.)
shell> cd /usr/local
3. Obtain a distribution file using the instructions in Section
2.1.3, "How to Get MariaDB." For a given release, binary
distributions for all platforms are built from the same MariaDB
source distribution.
4. Unpack the distribution, which creates the installation
directory. Then create a symbolic link to that directory:
shell> gunzip < /path/to/mysql-VERSION-OS.tar.gz | tar xvf -
shell> ln -s full-path-to-mysql-VERSION-OS mysql
The tar command creates a directory named mysql-VERSION-OS.
The ln command makes a symbolic link to that directory. This
lets you refer more easily to the installation directory as
/usr/local/mysql.
With GNU tar, no separate invocation of gunzip is necessary.
You can replace the first line with the following alternative
command to uncompress and extract the distribution:
shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz
5. Change location into the installation directory:
shell> cd mysql
You will find several files and subdirectories in the mysql
directory. The most important for installation purposes are
the bin and scripts subdirectories:
+ The bin directory contains client programs and the
server. You should add the full path name of this
directory to your PATH environment variable so that your
shell finds the MariaDB programs properly. See Section
2.14, "Environment Variables."
+ The scripts directory contains the mysql_install_db
script used to initialize the mysql database containing
the grant tables that store the server access
permissions.
6. Ensure that the distribution contents are accessible to mysql.
If you unpacked the distribution as mysql, no further action
is required. If you unpacked the distribution as root, its
contents will be owned by root. Change its ownership to mysql
by executing the following commands as root in the
installation directory:
shell> chown -R mysql .
shell> chgrp -R mysql .
The first command changes the owner attribute of the files to
the mysql user. The second changes the group attribute to the
mysql group.
7. If you have not installed MariaDB before, you must create the
MariaDB data directory and initialize the grant tables:
shell> scripts/mysql_install_db --user=mysql
If you run the command as root, include the --user option as
shown. If you run the command while logged in as that user,
you can omit the --user option.
The command should create the data directory and its contents
with mysql as the owner.
After creating or updating the grant tables, you need to
restart the server manually.
8. Most of the MariaDB installation can be owned by root if you
like. The exception is that the data directory must be owned
by mysql. To accomplish this, run the following commands as
root in the installation directory:
shell> chown -R root .
shell> chown -R mysql data
9. If you want MariaDB to start automatically when you boot your
machine, you can copy support-files/mysql.server to the
location where your system has its startup files. More
information can be found in the support-files/mysql.server
script itself and in Section 2.13.1.2, "Starting and Stopping
MariaDB Automatically."
10. You can set up new accounts using the bin/mysql_setpermission
script if you install the DBI and DBD::mysql Perl modules. See
Section 4.6.14, "mysql_setpermission --- Interactively Set
Permissions in Grant Tables." For Perl module installation
instructions, see Section 2.15, "Perl Installation Notes."
11. If you would like to use mysqlaccess and have the MariaDB
distribution in some nonstandard location, you must change the
location where mysqlaccess expects to find the mysql client.
Edit the bin/mysqlaccess script at approximately line 18.
Search for a line that looks like this:
$MYSQL = '/usr/local/bin/mysql'; # path to mysql executable
Change the path to reflect the location where mysql actually
is stored on your system. If you do not do this, a Broken pipe
error will occur when you run mysqlaccess.
After everything has been unpacked and installed, you should test
your distribution. To start the MariaDB server, use the following
command:
shell> bin/mysqld_safe --user=mysql &
If you run the command as root, you must use the --user option as
shown. The value of the option is the name of the login account
that you created in the first step to use for running the server.
If you run the command while logged in as mysql, you can omit the
--user option.
If the command fails immediately and prints mysqld ended, you can
find some information in the host_name.err file in the data
directory.
More information about mysqld_safe is given in Section 4.3.2,
"mysqld_safe --- MySQL Server Startup Script."
Note
The accounts that are listed in the MariaDB grant tables initially
have no passwords. After starting the server, you should set up
passwords for them using the instructions in Section 2.13,
"Post-Installation Setup and Testing."

You can find information about how to install from a Windows source
distributions at
2.5.10. Installing MySQL from Source on Windows
http://dev.mysql.com/doc/refman/5.1/en/windows-source-build.html
These instructions describe how to build binaries from source for
MySQL 5.1 on Windows. Instructions are provided for building
binaries from a standard source distribution or from the Bazaar
tree that contains the latest development source.
The MySQL Reference Manual is also available in various formats on
http://dev.mysql.com/doc; if you're interested in the DocBook XML
sources go to http://svn.mysql.com.
Note
The instructions here are strictly for users who want to test
MySQL on Microsoft Windows from the latest source distribution or
from the Bazaar tree. For production use, we do not advise using a
MySQL server built by yourself from source. Normally, it is best
to use precompiled binary distributions of MySQL that are built
specifically for optimal performance on Windows by Oracle
Corporation. Instructions for installing binary distributions are
available in Section 2.5, "Installing MySQL on Windows."
To build MySQL on Windows from source, you must satisfy the
following system, compiler, and resource requirements:
* Windows 2000, Windows XP, or newer version.
Windows Vista is supported when using Visual Studio 2005
provided you have installed the following updates:
+ Microsoft Visual Studio 2005 Professional Edition - ENU
Service Pack 1 (KB926601)
(http://support.microsoft.com/?kbid=926601)
+ Security Update for Microsoft Visual Studio 2005
Professional Edition - ENU (KB937061)
(http://support.microsoft.com/?kbid=937061)
+ Update for Microsoft Visual Studio 2005 Professional
Edition - ENU (KB932232)
(http://support.microsoft.com/?kbid=932232)
* CMake, which can be downloaded from http://www.cmake.org.
After installing, modify your path to include the cmake
binary.
* Microsoft Visual C++ 2005 Express Edition, Visual Studio .Net
2003 (7.1), or Visual Studio 2005 (8.0) compiler system.
* If you are using Visual C++ 2005 Express Edition, you must
also install an appropriate Platform SDK. More information and
links to downloads for various Windows platforms is available
from
http://www.microsoft.com/downloads/details.aspx?familyid=0baf2
b35-c656-4969-ace8-e4c0c0716adb.
* If you are compiling from a Bazaar tree or making changes to
the parser, you need bison for Windows, which can be
downloaded from
http://gnuwin32.sourceforge.net/packages/bison.htm. Download
the package labeled "Complete package, excluding sources".
After installing the package, modify your path to include the
bison binary and ensure that this binary is accessible from
Visual Studio.
* Cygwin might be necessary if you want to run the test script
or package the compiled binaries and support files into a Zip
archive. (Cygwin is needed only to test or package the
distribution, not to build it.) Cygwin is available from
http://cygwin.com.
* 3GB to 5GB of disk space.
The exact system requirements for Visual Studio can be found here:
http://msdn.microsoft.com/vstudio/Previous/2003/sysreqs/default.as
px and
http://msdn.microsoft.com/vstudio/products/sysreqs/default.aspx
You also need a MySQL source distribution for Windows, which can
be obtained two ways:
* Obtain a source distribution packaged by Oracle Corporation.
These are available from http://dev.mysql.com/downloads/.
* Package a source distribution yourself from the latest Bazaar
developer source tree. For instructions on pulling the latest
source files, see Section 2.3.3, "Installing from the
Development Source Tree."
If you find something not working as expected, or you have
suggestions about ways to improve the current build process on
Windows, please send a message to the win32 mailing list. See
Section 1.6.1, "MySQL Mailing Lists."
2.5.10.1. Building MySQL from Source Using CMake and Visual Studio
You can build MySQL on Windows by using a combination of cmake and
Microsoft Visual Studio .NET 2003 (7.1), Microsoft Visual Studio
2005 (8.0), Microsoft Visual Studio 2008 (9.0) or Microsoft Visual
C++ 2005 Express Edition. You must have the appropriate Microsoft
Platform SDK installed.
Note
To compile from the source code on Windows you must use the
standard source distribution (for example, mysql-5.1.46.tar.gz).
You build from the same distribution as used to build MySQL on
Unix, Linux and other platforms. Do not use the Windows Source
distributions as they do not contain the necessary configuration
script and other files.
Follow this procedure to build MySQL:
1. If you are installing from a packaged source distribution,
create a work directory (for example, C:\workdir), and unpack
the source distribution there using WinZip or another Windows
tool that can read .zip files. This directory is the work
directory in the following instructions.
Note
You must run the commands in the win directory from the
top-level source directory. Do not change into the win
directory, as the commands will not be executed correctly.
2. Start a command shell. If you have not configured the PATH and
other environment variables for all command shells, you may be
able to start a command shell from the Start Menu within the
Windows Visual Studio menu that contains the necessary
environment changes.
3. Within the command shell, navigate to the work directory and
run the following command:
C:\workdir>win\configure.js options
If you have associated the .js file extension with an
application such as a text editor, then you may need to use
the following command to force configure.js to be executed as
a script:
C:\workdir>cscript win\configure.js options
These options are available for configure.js:
+ WITH_INNOBASE_STORAGE_ENGINE: Enable the InnoDB storage
engine.
+ WITH_PARTITION_STORAGE_ENGINE: Enable user-defined
partitioning.
+ WITH_ARCHIVE_STORAGE_ENGINE: Enable the ARCHIVE storage
engine.
+ WITH_BLACKHOLE_STORAGE_ENGINE: Enable the BLACKHOLE
storage engine.
+ WITH_EXAMPLE_STORAGE_ENGINE: Enable the EXAMPLE storage
engine.
+ WITH_FEDERATED_STORAGE_ENGINE: Enable the FEDERATED
storage engine.
+ WITH_NDBCLUSTER_STORAGE_ENGINE (experimental): Enable the
NDBCLUSTER storage engine in the MySQL server; cause
binaries for the MySQL Cluster management and data node,
management client, and other programs to be built.
This option is supported only in MySQL Cluster NDB 7.0
(NDBCLUSTER storage engine versions 6.4.0 and later)
using the MySQL Cluster sources. It cannot be used to
enable clustering support in other MySQL source trees or
distributions.
+ MYSQL_SERVER_SUFFIX=suffix: Server suffix, default none.
+ COMPILATION_COMMENT=comment: Server comment, default
"Source distribution".
+ MYSQL_TCP_PORT=port: Server port, default 3306.
+ DISABLE_GRANT_OPTIONS: Disables the --bootstrap,
--skip-grant-tables, and --init-file options for mysqld.
This option is available as of MySQL 5.1.15.
For example (type the command on one line):
C:\workdir>win\configure.js WITH_INNOBASE_STORAGE_ENGINE
WITH_PARTITION_STORAGE_ENGINE MYSQL_SERVER_SUFFIX=-pro
4. From the work directory, execute the win\build-vs9.bat
(Windows Visual Studio 2008), win\build-vs8.bat (Windows
Visual Studio 2005), or win\build-vs71.bat (Windows Visual
Stidion 2003) script, depending on the version of Visual
Studio you have installed. The script invokes CMake, which
generates the mysql.sln solution file.
You can also use the corresponding 64-bit file (for example
win\build-vs8_x64.bat or win\build-vs9_x64.bat) to build the
64-bit version of MySQL. However, you cannot build the 64-bit
version with Visual Studio Express Edition. You must use
Visual Studio 2005 (8.0) or higher.
5. From the work directory, open the generated mysql.sln file
with Visual Studio and select the proper configuration using
the Configuration menu. The menu provides Debug, Release,
RelwithDebInfo, MinRelInfo options. Then select Solution >
Build to build the solution.
Remember the configuration that you use in this step. It is
important later when you run the test script because that
script needs to know which configuration you used.
6. Test the server. The server built using the preceding
instructions expects that the MySQL base directory and data
directory are C:\mysql and C:\mysql\data by default. If you
want to test your server using the source tree root directory
and its data directory as the base directory and data
directory, you need to tell the server their path names. You
can either do this on the command line with the --basedir and
--datadir options, or by placing appropriate options in an
option file. (See Section 4.2.3.3, "Using Option Files.") If
you have an existing data directory elsewhere that you want to
use, you can specify its path name instead.
When the server is running in standalone fashion or as a
service based on your configuration, try to connect to it from
the mysql interactive command-line utility.
You can also run the standard test script, mysql-test-run.pl.
This script is written in Perl, so you'll need either Cygwin
or ActiveState Perl to run it. You may also need to install
the modules required by the script. To run the test script,
change location into the mysql-test directory under the work
directory, set the MTR_VS_CONFIG environment variable to the
configuration you selected earlier (or use the --vs-config
option), and invoke mysql-test-run.pl. For example (using
Cygwin and the bash shell):
shell> cd mysql-test
shell> export MTR_VS_CONFIG=debug
shell> ./mysql-test-run.pl --force --timer
shell> ./mysql-test-run.pl --force --timer --ps-protocol
When you are satisfied that the programs you have built are
working correctly, stop the server. Now you can install the
distribution. One way to do this is to use the make_win_bin_dist
script in the scripts directory of the MySQL source distribution
(see Section 4.4.2, "make_win_bin_dist --- Package MySQL
Distribution as ZIP Archive"). This is a shell script, so you must
have Cygwin installed if you want to use it. It creates a Zip
archive of the built executables and support files that you can
unpack in the location at which you want to install MySQL.
It is also possible to install MySQL by copying directories and
files directly:
1. Create the directories where you want to install MySQL. For
example, to install into C:\mysql, use these commands:
C:\> mkdir C:\mysql
C:\> mkdir C:\mysql\bin
C:\> mkdir C:\mysql\data
C:\> mkdir C:\mysql\share
C:\> mkdir C:\mysql\scripts
If you want to compile other clients and link them to MySQL,
you should also create several additional directories:
C:\> mkdir C:\mysql\include
C:\> mkdir C:\mysql\lib
C:\> mkdir C:\mysql\lib\debug
C:\> mkdir C:\mysql\lib\opt
If you want to benchmark MySQL, create this directory:
C:\> mkdir C:\mysql\sql-bench
Benchmarking requires Perl support. See Section 2.15, "Perl
Installation Notes."
2. From the work directory, copy into the C:\mysql directory the
following files and directories:
C:\> cd \workdir
C:\workdir> mkdir C:\mysql

If you want to compile other clients and link them to MySQL,
you should also copy several libraries and header files:
C:\workdir> copy lib\Release\mysqlclient.lib C:\mysql\lib\debug
C:\workdir> copy lib\Release\libmysql.* C:\mysql\lib\debug
C:\workdir> copy lib\Release\zlib.* C:\mysql\lib\debug

C:\workdir> copy lib\Release\libmysql.* C:\mysql\lib\opt
C:\workdir> copy lib\Release\zlib.* C:\mysql\lib\opt
C:\workdir> copy include\*.h C:\mysql\include
C:\workdir> copy libmysql\libmysql.def C:\mysql\include
Note
If you have compiled a Debug, rather than Release solution,
you can replace Release with Debug in the source file names
shown above.
If you want to benchmark MySQL, you should also do this:
C:\workdir> xcopy sql-bench\*.* C:\mysql\bench /E
After installation, set up and start the server in the same way as
for binary Windows distributions. This includes creating the
system tables by running mysql_install_db. For more information,
see Section 2.5, "Installing MySQL on Windows."

This file should contain all know fatal bugs in the Mariadb and the
Maria storage engine for the last source or binary release. Minor
bugs, extensions and feature request and bugs found since this release
can be find in the MariaDB bugs database at:
https://bugs.launchpad.net/maria and in the MySQL bugs databases at:
http://bugs.mysql.com/ (category "Maria storage engine").
There shouldn't normally be any bugs that affects normal operations in
any MariaDB release. Still, there are always exceptions and edge cases
and that's what this file is for.
If you have found a bug that is not listed here, please add it to
http://bugs.launchpad.net/maria so that we can either fix it for next
release or in the worst case add it here for others to know!
IMPORTANT:
If you have been using the Maria storage engine with
MySQL-5.1-Maria-alpha build and upgrading to a newer MariaDB you MUST
run maria_chk --recover on all your Maria tables. This is because we
made an incompatible change of how transaction id is stored and old
transaction id's must be reset!
cd mysql-data-directory
maria_chk --recover */*.MAI
As the Maria storage engine is now in beta we will do our best to not
introduce any incompatible changes in the data format for the Maria
tables; If this would be ever be needed, we will, if possible, support
both the old and the new version to make upgrades as easy as possible.
Note that for the MariaDB 5.1 release the Maria storage engine is
classified as 'beta'; It should work, but use it with caution. Please
report all bugs to https://bugs.launchpad.net/maria so that we can fix
them!

This is a release of MySQL, a dual-license SQL DBMS.
MySQL is brought to you by the MySQL team at Oracle Corporation.
This is a release of MariaDB.
MariaDB is designed as a drop-in replacement of MySQL(R) with more
features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by many of the original developers of MySQL
who now work for Monty Program Ab, and by many people in the
community.
MySQL, which is the base of MariaDB, is a product and trademark of Sun
Microsystems, Inc. For a list of developers and other contributors,
see the Credits appendix. You can also do 'SHOW authors' to get a
list of active contributors.
A description of the MariaDB project and a manual can be found at:
http://askmonty.org/wiki/index.php/MariaDB
http://askmonty.org/wiki/index.php/MariaDB_versus_MySQL
http://askmonty.org/wiki/index.php/Manual:Contents
As MariaDB is a full replacement of MySQL, the MySQL manual at
http://dev.mysql.com/doc is generally applicable.
More help is available from the Maria Discuss mailing list
https://launchpad.net/~maria-discuss
and the #maria IRC channel on Freenode.

GPLv2 Disclaimer
For the avoidance of doubt, except that if any license choice
other than GPL or LGPL is available it will apply instead, Oracle
elects to use only the General Public License version 2 (GPLv2)
at this time for any software where a choice of GPL license versions
is made available with the language indicating that GPLv2 or any

To build libevent, type
$ ./configure && make
(If you got libevent from the subversion repository, you will
first need to run the included "autogen.sh" script in order to
generate the configure script.)
Install as root via
# make install
You can run the regression tests by
$ make verify
Before, reporting any problems, please run the regression tests.
To enable the low-level tracing build the library as:
CFLAGS=-DUSE_DEBUG ./configure [...]

/*
* This file defines five types of data structures: singly-linked lists,
* lists, simple queues, tail queues, and circular queues.
*
*
* A singly-linked list is headed by a single forward pointer. The elements
* are singly linked for minimum space and pointer manipulation overhead at
* the expense of O(n) removal for arbitrary elements. New elements can be
* added to the list after an existing element or at the head of the list.
* Elements being removed from the head of the list should use the explicit
* macro for this purpose for optimum efficiency. A singly-linked list may
* only be traversed in the forward direction. Singly-linked lists are ideal
* for applications with large datasets and few or no removals or for
* implementing a LIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before
* or after an existing element or at the head of the list. A list
* may only be traversed in the forward direction.
*
* A simple queue is headed by a pair of pointers, one the head of the
* list and the other to the tail of the list. The elements are singly
* linked to save space, so elements can only be removed from the
* head of the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the
* list. A simple queue may only be traversed in the forward direction.
*
* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.
*
* A circle queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the list.
* A circle queue may be traversed in either direction, but has a more
* complex end of list detection.

/*
* This file defines data structures for different types of trees:
* splay trees and red-black trees.
*
* A splay tree is a self-organizing data structure. Every operation
* on the tree causes a splay to happen. The splay moves the requested
* node to the root of the tree and partly rebalances it.
*
* This has the benefit that request locality causes faster lookups as
* the requested nodes move to the top of the tree. On the other hand,
* every lookup causes memory writes.
*
* The Balance Theorem bounds the total access time for m operations
* and n inserts on an initially empty tree as O((m + n)lg n). The
* amortized cost for a sequence of m accesses to a splay tree is O(lg n);
*
* A red-black tree is a binary search tree with the node color as an
* extra attribute. It fulfills a set of conditions:
* - every search path from the root to a leaf consists of the
* same number of black nodes,
* - each red node (except for the root) has a black parent,
* - each leaf node is black.
*
* Every operation on a red-black tree is bounded as O(lg n).
* The maximum height of a red-black tree is 2lg (n+1).

/** @file evdns.h
*
* Welcome, gentle reader
*
* Async DNS lookups are really a whole lot harder than they should be,
* mostly stemming from the fact that the libc resolver has never been
* very good at them. Before you use this library you should see if libc
* can do the job for you with the modern async call getaddrinfo_a
* (see http://www.imperialviolet.org/page25.html#e498). Otherwise,
* please continue.
*
* This code is based on libevent and you must call event_init before
* any of the APIs in this file. You must also seed the OpenSSL random
* source if you are using OpenSSL for ids (see below).
*
* This library is designed to be included and shipped with your source
* code. You statically link with it. You should also test for the
* existence of strtok_r and define HAVE_STRTOK_R if you have it.
*
* The DNS protocol requires a good source of id numbers and these
* numbers should be unpredictable for spoofing reasons. There are
* three methods for generating them here and you must define exactly
* one of them. In increasing order of preference:
*
* DNS_USE_GETTIMEOFDAY_FOR_ID:
* Using the bottom 16 bits of the usec result from gettimeofday. This
* is a pretty poor solution but should work anywhere.
* DNS_USE_CPU_CLOCK_FOR_ID:
* Using the bottom 16 bits of the nsec result from the CPU's time
* counter. This is better, but may not work everywhere. Requires
* POSIX realtime support and you'll need to link against -lrt on
* glibc systems at least.
* DNS_USE_OPENSSL_FOR_ID:
* Uses the OpenSSL RAND_bytes call to generate the data. You must
* have seeded the pool before making any calls to this library.
*
* The library keeps track of the state of nameservers and will avoid
* them when they go down. Otherwise it will round robin between them.
*
* Quick start guide:
* #include "evdns.h"
* void callback(int result, char type, int count, int ttl,
* void *addresses, void *arg);
* evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf");
* evdns_resolve("www.hostname.com", 0, callback, NULL);
*
* When the lookup is complete the callback function is called. The
* first argument will be one of the DNS_ERR_* defines in evdns.h.
* Hopefully it will be DNS_ERR_NONE, in which case type will be
* DNS_IPv4_A, count will be the number of IP addresses, ttl is the time
* which the data can be cached for (in seconds), addresses will point
* to an array of uint32_t's and arg will be whatever you passed to
* evdns_resolve.
*
* Searching:
*
* In order for this library to be a good replacement for glibc's resolver it
* supports searching. This involves setting a list of default domains, in
* which names will be queried for. The number of dots in the query name
* determines the order in which this list is used.
*
* Searching appears to be a single lookup from the point of view of the API,
* although many DNS queries may be generated from a single call to
* evdns_resolve. Searching can also drastically slow down the resolution
* of names.
*
* To disable searching:
* 1. Never set it up. If you never call evdns_resolv_conf_parse or
* evdns_search_add then no searching will occur.
*
* 2. If you do call evdns_resolv_conf_parse then don't pass
* DNS_OPTION_SEARCH (or DNS_OPTIONS_ALL, which implies it).
*
* 3. When calling evdns_resolve, pass the DNS_QUERY_NO_SEARCH flag.
*
* The order of searches depends on the number of dots in the name. If the
* number is greater than the ndots setting then the names is first tried
* globally. Otherwise each search domain is appended in turn.
*
* The ndots setting can either be set from a resolv.conf, or by calling
* evdns_search_ndots_set.
*
* For example, with ndots set to 1 (the default) and a search domain list of
* ["myhome.net"]:
* Query: www
* Order: www.myhome.net, www.
*
* Query: www.abc
* Order: www.abc., www.abc.myhome.net
*
* Internals:
*
* Requests are kept in two queues. The first is the inflight queue. In
* this queue requests have an allocated transaction id and nameserver.
* They will soon be transmitted if they haven't already been.
*
* The second is the waiting queue. The size of the inflight ring is
* limited and all other requests wait in waiting queue for space. This
* bounds the number of concurrent requests so that we don't flood the
* nameserver. Several algorithms require a full walk of the inflight
* queue and so bounding its size keeps thing going nicely under huge
* (many thousands of requests) loads.
*
* If a nameserver loses too many requests it is considered down and we
* try not to use it. After a while we send a probe to that nameserver
* (a lookup for google.com) and, if it replies, we consider it working
* again. If the nameserver fails a probe we wait longer to try again
* with the next probe.

* evport.c: event backend using Solaris 10 event ports. See port_create(3C).
* This implementation is loosely modeled after the one used for select(2) (in
* select.c).
*
* The outstanding events are tracked in a data structure called evport_data.
* Each entry in the ed_fds array corresponds to a file descriptor, and contains
* pointers to the read and write events that correspond to that fd. (That is,
* when the file is readable, the "read" event should handle it, etc.)
*
* evport_add and evport_del update this data structure. evport_dispatch uses it
* to determine where to callback when an event occurs (which it gets from
* port_getn).
*
* Helper functions are used: grow() grows the file descriptor array as
* necessary when large fd's come in. reassociate() takes care of maintaining
* the proper file-descriptor/event-port associations.
*
* As in the select(2) implementation, signals are handled by evsignal.

* This header files provides basic support for an RPC server and client.
*
* To support RPCs in a server, every supported RPC command needs to be
* defined and registered.
*
* EVRPC_HEADER(SendCommand, Request, Reply);
*
* SendCommand is the name of the RPC command.
* Request is the name of a structure generated by event_rpcgen.py.
* It contains all parameters relating to the SendCommand RPC. The
* server needs to fill in the Reply structure.
* Reply is the name of a structure generated by event_rpcgen.py. It
* contains the answer to the RPC.
*
* To register an RPC with an HTTP server, you need to first create an RPC
* base with:
*
* struct evrpc_base *base = evrpc_init(http);
*
* A specific RPC can then be registered with
*
* EVRPC_REGISTER(base, SendCommand, Request, Reply, FunctionCB, arg);
*
* when the server receives an appropriately formatted RPC, the user callback
* is invokved. The callback needs to fill in the reply structure.
*
* void FunctionCB(EVRPC_STRUCT(SendCommand)* rpc, void *arg);
*
* To send the reply, call EVRPC_REQUEST_DONE(rpc);
*
* See the regression test for an example.
