Apache Portable Runtime Utility Library README

----------------------------------------------
4
The Apache Portable Runtime Utility Library provides a predictable
5
and consistent interface to underlying client library interfaces.
6
This API assures predictable if not identical behavior regardless
7
of which libraries are available on a given platform.
9
APR and its companion libraries are implemented entirely in C
10
and provide a common programming interface across a wide variety
11
of operating system platforms without sacrificing performance.
12
Currently supported platforms include:
20
To give a brief overview, the primary core
21
subsystems of APR-util 1.3 include the following:
23
Hashing and UUID services
24
Multiple SQL DBD client interfaces
25
Multiple flat-database DBM client interfaces
26
Typesafe function Hooks abstraction
27
LDAP SSL connections for a variety of LDAP toolkits
29
Date parsing rourtines
33
Relocatable Memory Management functions
34
String filename-style pattern matching
36
Charset translation (iconv based)
37
XML parsing (expat based)
39

43
Users of APR 0.9 should be aware that migrating to the APR 1.x
44
programming interfaces may require some adjustments; APR 1.x is
45
neither source nor binary compatible with earlier APR 0.9 releases.
46
Users of APR 1.x can expect consistent interfaces and binary backwards
47
compatibility throughout the entire APR 1.x release cycle, as defined
48
in our versioning rules:
50
http://apr.apache.org/versioning.html
52
APR is already used extensively by the Apache HTTP Server
53
version 2 and the Subversion revision control system, to
54
name but a few. We list all known projects using APR at
55
http://apr.apache.org/projects.html -- so please let us know
56
if you find our libraries useful in your own projects!
61
As of apr-util version 1.2.11, MySQL DBD driver is shipped as part of the
62
distribution. However, to avoid licensing incompatibilities, it is not
63
built by default. To enable MySQL support, use the --with-mysql option,
64
but be aware that the MySQL license may introduce licensing implications
65
for your compiled code. Similarly, the bindings for propritary drivers
66
such as Oracle (--with-oracle option) must also be explicitly enabled.
68
On windows, selection of supported drivers is via the environment values
69
DBD_LIST (for freetds, mysql, oracle, pgsql, sqlite2 and/or sqlite3)
70
and DBM_LIST (db and/or gdbm). DBD odbc and DBM sdbm are unconditionally
71
compiled and installed, do not include these in the list.
73
Whenever distributing apr-util in combination with database client
74
drivers, always review the license requirements of all components.
