Apache Portable Runtime Utility Library README
|
||
|
|
----------------------------------------------
|
||
|
|
|
||
|
|
The Apache Portable Runtime Utility Library provides a predictable
|
||
|
|
and consistent interface to underlying client library interfaces.
|
||
|
|
This API assures predictable if not identical behavior regardless
|
||
|
|
of which libraries are available on a given platform.
|
||
|
|
|
||
|
|
APR and its companion libraries are implemented entirely in C
|
||
|
|
and provide a common programming interface across a wide variety
|
||
|
|
of operating system platforms without sacrificing performance.
|
||
|
|
Currently supported platforms include:
|
||
|
|
|
||
|
|
UNIX variants
|
||
|
|
Windows
|
||
|
|
Netware
|
||
|
|
Mac OS X
|
||
|
|
OS/2
|
||
|
|
|
||
|
|
To give a brief overview, the primary core
|
||
|
|
subsystems of APR-util 1.3 include the following:
|
||
|
|
|
||
|
|
Hashing and UUID services
|
||
|
|
Multiple SQL DBD client interfaces
|
||
|
|
Multiple flat-database DBM client interfaces
|
||
|
|
Typesafe function Hooks abstraction
|
||
|
|
LDAP SSL connections for a variety of LDAP toolkits
|
||
|
|
MemCache interface
|
||
|
|
Date parsing rourtines
|
||
|
|
Resource Lists
|
||
|
|
Thread Pools
|
||
|
|
Queues
|
||
|
|
Relocatable Memory Management functions
|
||
|
|
String filename-style pattern matching
|
||
|
|
URI Parsing
|
||
|
|
Charset translation (iconv based)
|
||
|
|
XML parsing (expat based)
|
||
|
|
|
||
|
|

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

Cryptographic Software Notice
|
||
|
|
-----------------------------
|
||
|
|
This distribution includes cryptographic software. The country in
|
||
|
|
which you currently reside may have restrictions on the import,
|
||
|
|
possession, use, and/or re-export to another country, of
|
||
|
|
encryption software. BEFORE using any encryption software, please
|
||
|
|
check your country's laws, regulations and policies concerning the
|
||
|
|
import, possession, or use, and re-export of encryption software, to
|
||
|
|
see if this is permitted. See http://www.wassenaar.org/ for more
|
||
|
|
information.
|
||
|
|
|
||
|
|
The U.S. Government Department of Commerce, Bureau of Industry and
|
||
|
|
Security (BIS), has classified this software as Export Commodity
|
||
|
|
Control Number (ECCN) 5D002.C.1, which includes information security
|
||
|
|
software using or performing cryptographic functions with asymmetric
|
||
|
|
algorithms. The form and manner of this Apache Software Foundation
|
||
|
|
distribution makes it eligible for export under the License Exception
|
||
|
|
ENC Technology Software Unrestricted (TSU) exception (see the BIS
|
||
|
|
Export Administration Regulations, Section 740.13) for both object
|
||
|
|
code and source code.
|
||
|
|
|
||
|
|
The following provides more details on the included cryptographic
|
||
|
|
software:
|
||
|
|
|
||
|
|
APR-Util provides an abstract interface for symmetrical cryptographic
|
||
|
|
functions that make use of a general-purpose encryption library,
|
||
|
|
such as OpenSSL, NSS, or the operating system's platform-specific
|
||
|
|
facilities. This interface is known as the apr_crypto interface,
|
||
|
|
with implementation beneath the /crypto directory.
|
||
|
|
|
||
|
|
APR-Util provides an abstract interface for SSL encrypted LDAP (ldaps
|
||
|
|
and STARTTLS style) connections, which can be powered by OpenLDAP,
|
||
|
|
Netscape LDAP SDK, Mozilla LDAP SDK, or other platform specific ldap
|
||
|
|
interfaces.
