New Revision: 1937749
Log:
Replace the 'Dependency Overview' section with a brief list of dependencies.
Fold the content of 'Dependency Overview' into 'DEPENDENCIES IN DETAIL', so
that the content remains in the document.
Currently, two sections related to dependencies duplicate each other. This
change eliminates this duplication and provide a simple, skimmable list of
dependencies at the beginning of the document rather than an elaborate
per-dependency summary (which is still available in section V).
* INSTALL
(I.B): Replace the content with a brief list of dependencies.
(V): Fold the earlier content of I.B into V, verbatim where possible. Some
text is skipped since it duplicates a content that is already present in V.

Subversion also depends on the following third-party libraries:

-
- * Expat (REQUIRED for client and server)
-
- Subversion uses the Expat library for XML parsing.
-
- * SQLite (REQUIRED for client and server)
-
- Subversion uses SQLite to manage some internal databases.
-
- * Zlib (REQUIRED for client and server)
-
- Subversion uses zlib for compressing binary differences.
- These diff streams are used everywhere -- over the network,
- in the repository, and in the client's working copy.
-
- * LZ4 (REQUIRED for client and server)
-
- Subversion uses the LZ4 library for compression. If it is not
- detected at compile time, a copy bundled with the Subversion sources
- can be used.
-
- * utf8proc (REQUIRED for client and server)
-
- Subversion uses utf8proc for UTF-8 support, including Unicode
- normalization.
-
- * Apache Serf (OPTIONAL for client)
-
- The Apache Serf library enables the Subversion client to access
- repositories over http:// and https:// URLs. Apache Serf uses OpenSSL
- for the encrypted https:// communication.
-
- * Berkeley DB (DEPRECATED, TO BE REMOVED IN THE FUTURE)
-
- Needed only for the deprecated BDB repository backend. Support for
- BDB is planned to be removed completely in the future.
-
- The CMake build system does not support building with BDB.
-
- * libsasl (OPTIONAL for client and server)
-
- If the Cyrus SASL library is detected at compile time, then
- the svn client (and svnserve server) will be able to utilize
- SASL to do various forms of authentication when speaking the
- svnserve protocol.
-
- * Python, Perl, Java, Ruby (OPTIONAL)
-
- Subversion is mostly a collection of C libraries with
- well-defined APIs, with a small collection of programs that
- use the APIs. If you want to build Subversion API bindings
- for other languages, you need to have those languages
- available at build time.
-
- * py3c (OPTIONAL, but REQUIRED for Python bindings)
-
- The Python 3 Compatibility Layer for C Extensions is required
- to build the Python language bindings.
-
- * KDE Framework 5, libsecret, GNOME Keyring (OPTIONAL for client)
-
- Subversion contains optional support for storing passwords in
- KWallet via KDE Framework 5 libraries (preferred) or kdelibs4,
- and GNOME Keyring via libsecret (preferred) or GNOME APIs.
-
- * libmagic (OPTIONAL)
-
- If the libmagic library is detected at compile time,
- it will be used to determine mime-types of binary files
- which are added to version control. Note that mime-types
- configured via auto-props or the mime-types-file option
- take precedence.
+ Required:
+ * APR and APR-Util 1.4 or later -- the portability layer that allows
+ Subversion to run on different operating systems.
+ * Expat -- XML parsing.
+ * zlib -- compression of binary diffs, used everywhere.
+ * LZ4 r129 or later -- compression. A bundled copy can be used.
