39I.    INTRODUCTION
40      ============
41
42  A. Audience
43
44      This document is written for people who intend to build
45      Subversion from source code.  Normally, the only people who do
46      this are Subversion developers and package maintainers.
47
48      If neither of these labels fits you, we recommend you find an
49      appropriate binary package of Subversion and install that.
50      While the Subversion project doesn't officially release binary
51      packages, a number of volunteers have made such packages
52      available for different operating systems.  Most Linux and BSD
53      distributions already have Subversion packages ready to go via
54      standard packaging channels, and other volunteers have built
55      'installers' for both Windows and OS X.  Visit this page for
56      package links:
57
58         https://subversion.apache.org/packages.html
59
60      For those of you who still wish to build from source, Subversion
61      follows the Unix convention of "./configure && make", but it has
62      a number of dependencies.
63
64
65  B. Dependency Overview
66
67      You'll need the following build tools to compile Subversion:
68
69      * autoconf 2.59 or later (Unix only)
70      * libtool 1.4 or later (Unix only)
71      * a reasonable C compiler (gcc, Visual Studio, etc.)
72
73
74      Subversion also depends on the following third-party libraries:
75
76      * libapr and libapr-util (REQUIRED for client and server)
77
78         The Apache Portable Runtime (APR) library provides an
79         abstraction of operating-system level services such as file
80         and network I/O, memory management, and so on.  It also
81         provides convenience routines for things like hashtables,
82         checksums, and argument processing.  While it was originally
83         developed for the Apache HTTP server, APR is a standalone
84         library used by Subversion and other products.  It is a
85         critical dependency for all of Subversion; it's the layer
86         that allows Subversion clients and servers to run on
87         different operating systems.
88
89      * SQLite  (REQUIRED for client and server)
90
91         Subversion uses SQLite to manage some internal databases.
92
93      * libz  (REQUIRED for client and server)
94
95         Subversion uses zlib for compressing binary differences.
96         These diff streams are used everywhere -- over the network,
97         in the repository, and in the client's working copy.
98
99      * Apache Serf  (OPTIONAL for client)
100
101         The Apache Serf library allows the Subversion client to send HTTP
102         requests.  This is necessary if you want your client to access
103         a repository served by the Apache HTTP server.  There is an
104         alternate 'svnserve' server as well, though, and clients
105         automatically know how to speak the svnserve protocol.
106         Thus it's not strictly necessary for your client to be able
107         to speak HTTP... though we still recommend that your client
108         be built to speak both HTTP and svnserve protocols.
109
110      * OpenSSL (OPTIONAL for client and server)
111
112         OpenSSL enables your client to access SSL-encrypted https://
113         URLs (using Apache Serf) in addition to unencrypted http:// URLs.
114         To use SSL with Subversion's WebDAV server, Apache needs to be
115         compiled with OpenSSL as well.
116
117      * Netwide Assembler (OPTIONAL for client and server)
118
119        The Netwide Assembler (NASM) is used to build the (optionally)
120        assembler modules of OpenSSL.  As of OpenSSL 1.1.0 NASM is the
121        only supported assembler.
122
123      * Berkeley DB (OPTIONAL for client and server)
124
125         There are two different repository 'back-end'
126         implementations.  One implementation stores data in a flat
127         filesystem (known as FSFS); the other implementation stores
128         data in a Berkeley DB database (known as BDB).  When you
129         create a repository, you have the option of specifying a
130         storage back-end.  The Berkeley DB back-end will only be
131         available if the BDB libraries are discovered at compile
132         time.  The Berkeley DB back-end has been deprecated and
133         is not recommend.
134
135      * libsasl (OPTIONAL for client and server)
136
137         If the Cyrus SASL library is detected at compile time, then
138         the svn client (and svnserve server) will be able to utilize
139         SASL to do various forms of authentication when speaking the
140         svnserve protocol.
141
142      * Python, Perl, Java, Ruby  (OPTIONAL)
143
144         Subversion is mostly a collection of C libraries with
145         well-defined APIs, with a small collection of programs that
146         use the APIs.  If you want to build Subversion API bindings
147         for other languages, you need to have those languages
148         available at build time.
149
150      * KDELibs, GNOME Keyring  (OPTIONAL for client)
151
152         Subversion contains optional support for storing passwords in
153         KWallet (KDE 4) or GNOME Keyring.
154
155      * libmagic (OPTIONAL)
156
157         If the libmagic library is detected at compile time,
158         it will be used to determine mime-types of binary files
159         which are added to version control. Note that mime-types
160         configured via auto-props or the mime-types-file option
161         take precedence.
162
163      * Googlemock aka Gmock (OPTIONAL)
164
165         This optional package is used by the tests for Subversions'
166         C++ bindings.
167
168
169  C. Dependencies in Detail
170
171      Subversion depends on a number of third party tools and libraries.
172      Some of them are only required to run a Subversion server; others
173      are necessary just for a Subversion client.  This section explains
174      what other tools and libraries will be required so that Subversion
175      can be built with the set of features you want.
176
177      On Unix systems, the './configure' script will tell you if you are
178      missing the correct version of any of the required libraries or
179      tools, so if you are in a real hurry to get building, you can skip
180      straight to section II.  If you want to gather the pieces you will
181      need before starting out, however, you should read the following.
182
183      If you're just installing a Subversion client, the Subversion
184      team has created a script that downloads the minimal prerequisite
185      libraries (Apache Portable Runtime, Sqlite, and Zlib).  The script,
186      'get-deps.sh', is available in the same directory as this file.
187      When run, it will place 'apr', 'apr-util', 'serf', 'zlib', and
188      'sqlite-amalgamation' directories directly into your unpacked Subversion
189      distribution.  With the exception of sqlite-amalgamation, they will
190      still need to be configured, built and installed explicitly, and
191      Subversion's own configure script may need to be told where to find
192      them, if they were not installed in standard system locations.
193
194      Note: there are optional dependencies (such as OpenSSL, swig, and httpd)
195      which get-deps.sh does not download.
196
197      Note: Because previous builds of Subversion may have installed older
198      versions of these libraries, you may want to run some of the cleanup
199      commands described in section II.B before installing the following.
200
201
202      1.  Apache Portable Runtime 1.3 or newer  (REQUIRED)
203
204      Whenever you want to build any part of Subversion, you need the
205      Apache Portable Runtime (APR) and the APR Utility (APR-util)
206      libraries.
207
208      If you do not have a pre-installed APR and APR-util, you will need
209      to get these yourself:
210
211          https://apr.apache.org/download.cgi
212
213      On Unix systems, if you already have the APR libraries compiled and do
214      not wish to regenerate them from source code, then Subversion needs to
215      be able to find them.
216
217      There are a couple of options to "./configure" that tell it where
218      to look for the APR and APR-util libraries. By default it will try
219      to locate the libraries using apr-config and apu-config scripts.
220      These scripts provide all the relevant information for the APR and
221      APR-util installations.
222
223      If you want to specify the location of the APR library, you can use
224      the "--with-apr=" option of "./configure". It should be able to find
225      the apr-config script in the standard location under that directory
226      (e.g. ${prefix}/bin).
227
228      Similarly, you can specify the location of APR-util using the
229      "--with-apr-util=" option to "./configure". It will look for the
230      apu-config script relative to that directory.
231
232      For example, if you want to use the APR libraries you built
233      with the Apache httpd server, you could run:
234
235          $ ./configure --with-apr=/usr/local/apache2 \
236            --with-apr-util=/usr/local/apache2  ...
237
238      Be sure to use a native Windows SVN client (as opposed to
239      Cygwin's version) so that the .dsp files get carriage-returns at
240      the ends of their lines.  Otherwise Visual Studio will complain
241      that it doesn't recognize the .dsp files.
242
243      If you use APR libraries checked out from svn in an Unix
244      environment, you need to run the 'buildconf' script in each
245      library's directory, to regenerate the configure scripts and
246      other files required for compiling the libraries:
247
248      $ cd apr; ./buildconf; ./configure ...; make; make install; cd ..
249
250      $ cd apr-util; ./buildconf; ./configure ...; make; make install; cd ..
251
252      Configure build and install both libraries before running Subversion's
253      configure script.
254
255
256      2. Zlib  (REQUIRED)
257
258         Subversion's binary-differencing engine depends on zlib for
259         compression.   Most Unix systems have libz pre-installed, but
260         if you need it, you can get it from
261
262            http://www.zlib.net/
263
264
265      3.  autoconf 2.59 or newer (Unix only)
266
267      This is required only if you plan to build from the latest source
268      (see section II.B). Generally only developers would be doing this.
269
270
271      4.  libtool 1.4 or newer (Unix only)
272
273      This is required only if you plan to build from the latest source
274      (see section II.B).
275
276      Note: Some systems (Solaris, for example) require libtool 1.4.3 or
277      newer. The autogen.sh script knows about that.
278
279
280      5.  Apache Serf library 1.3.4 or newer (OPTIONAL)
281
282      If you want your client to be able to speak to an Apache
283      server (via a http:// or https:// URL), you must link against
284      Apache Serf.  Though optional, we strongly recommend this.
285
286      In order to use ra_serf, you must install serf, and run Subversion's
287      ./configure with the argument --with-serf.  If serf is installed in a
288      non-standard place, you should use
289
290               --with-serf=/path/to/serf/install
291
292      instead.
293
294      Apache Serf can be obtained via your system's package distribution
295      system or directly from http://code.google.com/p/serf/.
296
297      For more information on Apache Serf and Subversion's ra_serf, see the
298      file subversion/libsvn_ra_serf/README.
299
300      6. OpenSSL  (OPTIONAL)
301
302      ### needs some updates. I think Apache Serf automagically handles
303      ### finding OpenSSL, but we may need more docco here. and w.r.t
304      ### zlib.
305
306      The Apache Serf library has support for SSL encryption by relying on the
307      OpenSSL library.
308
309        a. Using OpenSSL on the client through Apache Serf
310
311          On Unix systems, to build Apache Serf with OpenSSL, you need OpenSSL
312          installed on your system, and you must add "--with-ssl" as a
313          "./configure" parameter.  If your OpenSSL installation is hard
314          for Apache Serf to find, you may need to use
315          "--with-libs=/path/to/lib" in addition.  In particular, on Red Hat
316          (but not Fedora Core) it is necessary to specify
317          "--with-libs=/usr/kerberos" for OpenSSL to be found.  You can also
318          specify a path to the zlib library using "--with-libs".
319
320          Under Windows, you can specify the paths to these libraries by
321          passing the options --with-zlib and --with-openssl to gen-make.py.
322
323        b. Using OpenSSL on the Apache server
324
325          You can also add support for these features to an Apache httpd
326          server to be used for Subversion using the same support libraries.
327          The Subversion build system will not provide them, however.  You
328          add them by specifying parameters to the "./configure" script of
329          the Apache Server instead.
330
331          For getting SSL on your server, you would add the "--enable-ssl"
332          or "--with-ssl=/path/to/lib" option to Apache's "./configure"
333          script.  Apache enables zlib support by default, but you can
334          specify a nonstandard location for the library with the
335          "--with-z=/path/to/dir" option.  Consult the Apache documentation
336          for more details, and for other modules you may wish to install
337          to enhance your Subversion server.
338
339      If you don't already have it, you can get a copy of OpenSSL,
340      including instructions for building and packaging on both Unix
341      systems and Windows, at:
342
343          https://www.openssl.org/
344
345
346      7.  Berkeley DB 4.X  (OPTIONAL)
347
348      Berkeley DB is needed to build a Subversion server that supports
349      the BDB repository filesystem, or to access a BDB repository on
350      local disk.  If you will only use the FSFS repository filesystem,
351      or if you are building a Subversion client that will only speak
352      to remote (networked) repositories, you don't need it.
353
354      The current recommended version is 4.4.20 or newer, which brings
355      auto-recovery functionality to the Berkeley DB database
356      environment.
357
358      If you must use an older version of Berkeley DB, we *strongly*
359      recommend using 4.3 or 4.2 over the 4.1 or 4.0 versions.  Not
360      only are these significantly faster and more stable, but they
361      also enable Subversion repositories to automatically clean up
362      database journal files to save disk space.
363
364      You'll need Berkeley DB installed on your system.  You can
365      get it from:
366
367      http://www.oracle.com/technetwork/database/database-technologies/berkeleydb/overview/index.html
368
369      If you have Berkeley DB installed in a place not searched by default
370      for includes and libraries, add something like this:
371
372          --with-berkeley-db=db.h:/usr/local/include/db4.7:/usr/local/lib/db4.7:db-4.7
373
374      to your `configure' switches, and the build process will use the
375      Berkeley DB header and library in the named directories.  You may
376      need to use a different path, of course.  Note that in order for
377      the detection to succeed, the dynamic linker must be able to find
378      the libraries at configure time.
379
380      If you are on the Windows platform and want to build Subversion,
381      a precompiled version of the Berkeley DB library is available for
382      download at the Subversion web site "Documents & files" area:
383
384          http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=688
385
386      Look in the "Releases > Windows > Windows BDB" section.
387
388
389      8.  Cyrus SASL library (OPTIONAL)
390
391      If the Simple Authentication and Security Layer (SASL) library
392      is detected on your system, then the Subversion client and
393      svnserve server can utilize its abilities for various forms of
394      authentication.  To learn more about SASL or to get the source
395      code, visit:
396
397         http://freshmeat.net/projects/cyrussasl/
398
399
400      9.  Apache Web Server 2.2.X or newer  (OPTIONAL)
401
402          (https://httpd.apache.org/download.cgi)
403
404      The Apache httpd server is one of two methods to make your Subversion
405      repository available over a network - the other is a custom server
406      program called svnserve, which requires no extra software packages.
407      Building Subversion, the Apache server, and the modules that Apache
408      needs to communicate with Subversion are complicated enough that there
409      is a whole section at the end of this document that describes how it
410      is done: See section III for details.
411
412
413      10.  Python 2.7 or newer (https://www.python.org/)  (OPTIONAL)
414
415      If you want to run "make check" or build from the latest source
416      under Unix/Windows as described in section II.B, II.E and III.D,
417      install Python 2.7 or higher on your system. The majority of the
418      test suite is written in Python, as is part of Subversion's build
419      system.
420
421      Note that Python 3.x is not supported and most likely won't work.
422
423
424      11. Perl 5.8 or newer (Windows only)  (OPTIONAL)
425
426      To build Subversion under any of the MS Windows platforms, you
427      will also need Perl 5.8 or newer to run apr-util's w32locatedb.pl
428      script.
429
430
431      12. SQLite  (REQUIRED)
432
433      Subversion requires SQLite version 3.8.2 or above.  You can meet this
434      dependency several ways:
435        * Use an SQLite amalgamation file.
436        * Specify an SQLite installation to use.
437        * Let Subversion find an installed SQLite.
438
439      To use an SQLite-provided amalgamation, just drop sqlite3.c into
440      Subversion's sqlite-amalgamation/ directory, or point to it with the
441      --with-sqlite configure option.  This file also ships with the Subversion
442      dependencies distribution, or you can download it from SQLite:
443
444          https://www.sqlite.org/download.html
445
446
447      13. pkg-config  (Unix only, OPTIONAL)
448
449      Subversion uses pkg-config to find appropriate options used
450      at build time.
451
452
453      14. D-Bus  (Unix only, OPTIONAL)
454
455      D-Bus is a message bus system. D-Bus is required for support for KWallet
456      and GNOME Keyring. pkg-config is needed to find D-Bus headers and library.
457
458
459      15. Qt 4  (Unix only, OPTIONAL)
460
461      Qt is a cross-platform application framework. QtCore, QtDBus and QtGui
462      modules are required for support for KWallet. pkg-config is needed
463      to find Qt headers and libraries.
464
465
466      16. KDELibs 4  (Unix only, OPTIONAL)
467
468      Subversion contains optional support for storing passwords in KWallet.
469      KDELibs contains core KDE libraries. Subversion uses libkdecore and libkdeui
470      libraries when support for KWallet is enabled. kde4-config is used to get
471      some necessary options. pkg-config, D-Bus and Qt 4 are also required.
472      If you want to build support for KWallet, then pass the '--with-kwallet'
473      option to `configure`. If KDE is installed in a non-standard prefix, then
474      use:
475
476          --with-kwallet=/path/to/KDE/prefix
477
478      17. GLib 2  (Unix only, OPTIONAL)
479
480      GLib is a general-purpose utility library. GLib is required for support
481      for GNOME Keyring. pkg-config is needed to find GLib headers and library.
482
483
484      18. GNOME Keyring  (Unix only, OPTIONAL)
485
486      Subversion contains optional support for storing passwords in GNOME Keyring.
487      pkg-config is needed to find GNOME Keyring headers and library. D-Bus and
488      GLib are also required. If you want to build support for GNOME Keyring,
489      then pass the '--with-gnome-keyring' option to `configure`.
490
491
492      19. Ctypesgen  (OPTIONAL)
493
494      Ctypesgen is Python wrapper generator for ctypes. It is used to generate
495      a part of Subversion Ctypes Python bindings (CSVN). If you want to build
496      CSVN, then pass the '--with-ctypesgen' option to `configure`. If ctypesgen.py
497      is installed in a non-standard place, then use:
498
499          --with-ctypesgen=/path/to/ctypesgen.py
500
501      For more information on CSVN, see subversion/bindings/ctypes-python/README.
502
503      20. libmagic (OPTIONAL)
504
505      Subversion's configure script attempts to find libmagic automatically.
506      If it is installed in a non-standard location, then use:
507
508        --with-libmagic=/path/to/libmagic/prefix
509
510      The files include/magic.h and lib/libmagic.so.1.0 (or similar)
511      are expected beneath this prefix directory. If they cannot be
512      found Subversion will be compiled without support for libmagic.
513
514      If libmagic is installed but support for it should not be compiled
515      in, then use:
516
517        --with-libmagic=no
518
519      If configure should fail when libmagic is not present, but only
520      the default locations should be searched, then use:
521
522        --with-libmagic
523
524      21. Googlemock (OPTIONAL)
525
526      Googlemock can be installed and built in-tree by invoking
527
528      $ ./get-dep.sh gmock
529
530      22. LZ4 (OPTIONAL)
531
532      Subversion uses LZ4 compression libary version r129 or above. Configure
533      will attempt to locate the system library by default using pkg-config
534      and known paths.
535
536      If it is installed in a non-standard location, then use:
537
538        --with-lz4=/path/to/liblz4
539
540      If configure should use the version bundled with the sources, use:
541        --with-lz4=internal
542
543  D. Documentation
544
545      The primary documentation for Subversion is the free book
546      "Version Control with Subversion", a.k.a. "The Subversion Book",
547      obtainable from http://svnbook.red-bean.com/.
548
549      Various additional documentation exists in the doc/ subdirectory of
550      the Subversion source.  See the file doc/README for more information.

553
554II.   INSTALLATION
555      ============
556
557  A.  Building from a Tarball
558      ------------------------------
559
560      1.  Building from a Tarball
561
562      Download the most recent distribution tarball from:
563
564          https://subversion.apache.org/download/
565
566      Unpack it, and use the standard GNU procedure to compile:
567
568          $ ./configure
569          $ make
570          # make install
571
572      You can also run the full test suite by running 'make check'.  Even
573      in successful runs, some tests will report XFAIL; that is normal.
574      Failed runs are indicated by FAIL or XPASS results, or a non-zero exit
575      code from "make check".
576
577
578  B.  Building the Latest Source under Unix
579      -------------------------------------
580
581      These instructions assume you have already installed Subversion
582      and checked out a working copy of Subversion's own code --
583      either the latest /trunk code, or some branch or tag.  You also
584      need to have already installed whatever prerequisites that
585      version of Subversion requires (if you haven't, the ./configure
586      step should complain).
587
588      You can discard the directory created by the tarball; you're
589      about to build the latest, greatest Subversion client.  This is
590      the procedure Subversion developers use.
591
592      First off, if you have any Subversion libraries lying around
593      from previous 'make installs', clean them up first!
594
595          # rm -f /usr/local/lib/libsvn*
596          # rm -f /usr/local/lib/libapr*
597          # rm -f /usr/local/lib/libserf*
598
599      Start the process by running "autogen.sh":
600
601          $ sh ./autogen.sh
602
603      This script will make sure you have all the necessary components
604      available to build Subversion.  If any are missing, you will be
605      told where to get them from.  (See the 'Dependency Overview' in
606      section I.)
607
608      Note: if the command "autoconf" on your machine does not run
609      autoconf 2.59 or later, but you do have a new enough autoconf
610      available, then you can specify the correct one with the
611      AUTOCONF variable.  (The AUTOHEADER variable is similar.)  This
612      may be required on Debian GNU/Linux, where "autoconf" is
613      actually a Perl script that attempts to guess which version is
614      required -- because of the interaction between Subversion's and
615      APR's configuration systems, the Perl script may get it wrong.
616      So for example, you might need to do:
617
618          $ AUTOCONF=autoconf2.59 sh ./autogen.sh
619
620      Once you've prepared the working copy by running autogen.sh,
621      just follow the usual configuration and build procedure:
622
623          $ ./configure
624          $ make
625          # make install
626
627      (Optionally, you might want to pass --enable-maintainer-mode to
628      the ./configure script.  This enables debugging symbols in your
629      binaries (among other things) and most Subversion developers use it.)
630
631      Since the resulting binary depends on shared libraries, the
632      destination library directory must be identified in your
633      operating system's library search path. That is in either
634      /etc/ld.so.conf or $LD_LIBRARY_PATH for Linux systems and in
635      /etc/rc.conf for FreeBSD, followed by a run of the 'ldconfig'
636      program. Check your system documentation for details. By
637      identifying the destination directory, Subversion will be able
638      to dynamically load repository access plugins.  If you try to do
639      a checkout and see an error like:
640
641      subversion/libsvn_ra/ra_loader.c:209: (apr_err=170000)
642      svn: Unrecognized URL scheme 'https://svn.apache.org/repos/asf/subversion/trunk'
643
644      It probably means that the dynamic loader/linker can't find all
645      of the libsvn_* libraries.
646
647
648  C.  Building under Unix in Different Directories
649      --------------------------------------------
650
651      It is possible to configure and build Subversion on Unix in a
652      directory other than the working copy. For example
653
654          $ svn co https://svn.apache.org/repos/asf/subversion/trunk svn
655          $ cd svn
656          $ # get SQLite amalgamation if required
657          $ chmod +x autogen.sh
658          $ ./autogen.sh
659          $ mkdir ../obj
660          $ cd ../obj
661          $ ../svn/configure [...with options as appropriate...]
662          $ make
663
664      puts the Subversion working copy in the directory svn and builds
665      it in a separate, parallel directory obj.
666
667      Why would you want to do this? Well there are a number of
668      reasons...
669
670          *  You may prefer to avoid "polluting" the working copy with
671             files generated during the build.
672
673          *  You may want to put the build directory and the working
674             copy on different physical disks to improve performance.
675
676          *  You may want to separate source and object code and only
677             backup the source.
678
679          *  You may want to remote mount the working copy on multiple
680             machines, and build for different machines from the same
681             working copy.
682
683          *  You may want to build multiple configurations from the
684             same working copy.
685
686      The last reason above is possibly the most useful.  For instance
687      you can have separate debug and optimized builds each using the
688      same working copy. Or you may want a client-only build and a
689      client-server build. Using multiple build directories you can
690      rebuild any or all configurations after an edit without the need
691      to either clean and reconfigure, or identify and copy changes
692      into another working copy.
693
694
695  D.  Installing from a Zip or Installer File under Windows
696      -----------------------------------------------------
697
698      Of all the ways of getting a Subversion client, this is the
699      easiest.  Download a Zip or self-extracting installer via:
700
701      https://subversion.apache.org/packages.html#windows
702
703      For a Zip file extract the DLLs and EXEs to a directory of your
704      choice. Included in the download are among other tools the SVN
705      client, the SVNADMIN administration tool and the SVNLOOK reporting
706      tool.
707
708      You may want to add the bin directory in the Subversion folder to your
709      PATH environment variable so as to not have to use the full path when
710      running Subversion commands.
711
712      To test the installation, open a DOS box (run either "cmd" or
713      "command" from the Start menu's "Run..." menu option), change to
714      the directory you installed the executables into, and run:
715
716          C:\test>svn co https://svn.apache.org/repos/asf/subversion/trunk svn
717
718      This will get the latest Subversion sources and put them into the
719      "svn" subdirectory.
720
721      If using a self-extracting .exe file, just run it instead of
722      unzipping it, to install Subversion.
723
724  E.  Building the Latest Source under Windows
725      ----------------------------------------
726
727  E.1 Prerequisites
728
729      * Microsoft Visual Studio. Any recent (2005+) version containing the
730        Visual C++ component will work (E.g. Professional, Express, Community
731        Edition). Make sure you enable C++ support during setup.
732      * Python 2.7 or higher, downloaded from https://www.python.org/ which is
733        used to generate the project files.
734        Note that Python 3.x is not supported (yet).
735      * Perl 5.8 or higher from https://www.perl.org/get.html
736      * Awk (from https://www.cs.princeton.edu/~bwk/btl.mirror/awk95.exe) is
737        needed to compile Apache.  Note that this is the actual awk program,
738        not an installer - just rename it to awk.exe and it is ready to use.
739      * Apache apr, apr-util, and optionally apr-iconv libraries, version
740        1.3 or later (1.2 for apr-iconv). If you are building from a Subversion
741        checkout and have not downloaded Apache 2, then get these 3 libraries
742        from https://www.apache.org/dist/apr/.
743      * SQLite 3.8.2 or higher from https://www.sqlite.org/download.html
744        (3.8.11.1 or higher recommended)
745      * ZLib 1.2 or higher is required and can be obtained from
746        http://www.zlib.net/
747      * Either a Subversion client binary from
748        https://subversion.apache.org/packages.html to do the initial checkout
749        of the Subversion source or the zip file source distribution.
750
751      Additional Options
752
753      * [Optional] Apache Httpd 2 source, downloaded from
754        https://httpd.apache.org/download.cgi, these instructions assume
755        version 2.0.58.  This is only needed for building the Subversion
756        server Apache modules.  ### FIXME Apache 2.2 or greater required.
757      * [Optional] Berkeley DB for backend support of the server components
758        are available from
759        http://www.oracle.com/technetwork/database/database-technologies/berkeleydb/downloads/index-082944.html
760        (Version 4.4.20 or in specific cases some higher version recommended)
761        For more information see Section I.C.7.
762      * [Optional] Openssl can be obtained from https://www.openssl.org/source/
763      * [Optional] NASM can be obtained from http://www.nasm.us/
764      * [Optional] A modified version of GNU libintl, called
765        svn-win32-libintl.zip, can be used for displaying localized
766        messages. Available at:
767        http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=2627
768      * [Optional] GNU gettext for generating message catalog (.mo)
769        files from message translations. You can get the latest
770        binaries from http://gnuwin32.sourceforge.net/. You'll need the
771        binaries (gettext-0.14.1-bin.zip) and dependencies
772        (gettext-0.14.1-dep.zip).
773
774  E.2 Notes
775
776      The Apache Serf library supports secure connections with OpenSSL
777      and on-the-wire compression with zlib. If you want to use the
778      secure connections feature, you should pass the option
779      "--with-openssl" to the gen-make.py script. See Section I.C.6 for
780      more details.
781
782  E.3 Preparation
783
784      This section describes how to unpack the files to make a build tree.
785
786      * Make a directory SVN and cd into it.
787      * Either checkout Subversion:
788
789          svn co https://svn.apache.org/repos/asf/subversion/trunk src-trunk
790
791        or unpack the zip file distribution and rename the directory to
792        src-trunk.
793
794      * Install Visual Studio Environment. You either have to tell the
795        installer to register environment variables or run VCVARS32.BAT
796        before building anything.  If you are using a newer Visual Studio,
797        use the 'Visual Studio 20xx Command Prompt' on the Start menu.
798      * Install Python and add it to your path
799      * Install Perl (it should add itself to the path)
800        ### Subversion doesn't need perl. Only some dependencies need it
801            (OpenSSL and some apr scripts)
802      * Copy AWK (awk95.exe) to awk.exe (e.g. SVN\awk\awk.exe) and add
803        the directory containing it (e.g. SVN\awk) to the path.
804        ### Subversion doesn't need awk. Only some dependencies need it
805            (some apr scripts)
806      * [Optional] Install NASM and add it to your path
807        ### Subversion doesn't need NASM. Only some dependencies need it
808            optionally (OpenSSL)
809      * [Optional] If you checked out Subversion from the repository and want
810        to build Subversion with http/https access support then install the
811        Apache Serf sources into SVN\src-trunk\serf.
812      * [Optional] If you want BDB backend support, extract the Berkeley DB
813        files into SVN\src-trunk\db4-win32. It's a good idea to add
814        SVN\src-trunk\db4-win32\bin to your PATH, so that Subversion can find
815        the Berkeley DB DLLs.
816
817        [NOTE: This binary package of Berkeley DB is provided for
818            convenience only. Please don't address questions about
819            Berkeley DB that aren't directly related to using Subversion
820            to the project mailing list.]
821
822        If you build Berkeley DB from the source, you will have to copy
823        the file db-x.x.x\build_win32\db.h to
824        SVN\src-trunk\db4-win32\include, and all the import libraries to
825        SVN\src-trunk\db4-win32\lib. Again, the DLLs should be somewhere in
826        your path.
827        ### Just use --with-serf instead of the hardcoded path
828
829      * [Optional] If you want to build the server modules, extract Apache
830        source into SVN\httpd-2.x.x.
831      * If you are building from a checkout of Subversion, and you are NOT
832        building Apache, then you will need the APR libraries.  Depending
833        on how you got your version of APR, either:
834          - Extract the APR, APR-util and APR-iconv source distributions into
835            SVN\apr, SVN\apr-util, and SVN\apr-iconv respectively.
836        Or:
837          - Extract the apr, apr-util and apr-iconv directories from the
838            srclib folder in the Apache httpd source into SVN\apr,
839            SVN\apr-util, and SVN\apr-iconv respectively.
840        ### Just use --with-apr, etc. instead of the hardcoded paths
841      * Extract the ZLib sources into SVN\zlib if you are not using the zlib
842        included in the dependencies zip file.
843        ### Just use --with-zlib instead of the hardcoded path
844      * [Optional] If you want secure connection (https) client support extract
845        OpenSSL into SVN\openssl
846        ### And pass the path to both serf and gen-make.py
847      * [Optional] If you want localized message support, extract
848        svn-win32-libintl.zip into SVN\svn-win32-libintl and extract
849        gettext-x.x.x-bin.zip and gettext-x.x.x-dep.zip into
850        SVN\gettext-x.x.x-bin.
851        Add SVN\gettext-x.x.x-bin\bin to your path.

857  E.4 Building the Binaries
858
859      To build the binaries either follow the instructions here or use
860      build\win32\vc6-build.bat.in after editing its default paths to match
861      yours and saving it as vc6-build.bat.  The vc6-build.bat does a full build
862      using all options so it requires Apache 2 source and the other optional
863      components.
864
865      Start in the SVN directory you created.
866
867      Set up the environment (commands should be one line even if wrapped here).
868
869      C:>set VER=trunk
870      C:>set DIR=trunk
871      C:>set BUILD_ROOT=C:\SVN
872      C:>set PYTHONDIR=C:\Python27
873      C:>set AWKDIR=C:\SVN\Awk
874      C:>set ASMDIR=C:\SVN\asm
875      C:>set SDKINC="C:\Program Files\Microsoft SDK\include"
876      C:>set SDKLIB="C:\Program Files\Microsoft SDK\lib"
877      C:>set GETTEXTBIN=C:\SVN\gettext-0.14.1-bin\bin
878      C:>PATH=%PATH%;%BUILD_ROOT%\src-%DIR%\db4-win32;%ASMDIR%;
879              %PYTHONDIR%;%AWKDIR%;%GETTEXTBIN%
880      C:>set INCLUDE=%SDKINC%;%INCLUDE%
881      C:>set LIB=%SDKLIB%;%LIB%
882
883      OpenSSL < 1.1.0
884
885      C:>cd openssl
886      C:>perl Configure VC-WIN32
887  [*] C:>call ms\do_masm
888      C:>nmake -f ms\ntdll.mak
889      C:>cd out32dll
890      C:>call ..\ms\test
891      C:>cd ..\..
892
893      *Note: Use "call ms\do_nasm" if you have nasm instead of MASM, or
894             "call ms\do_ms" if you don't have an assembler.
895             Also if you are using OpenSSL >= 1.0.0 masm is no longer
896             supported. You will have to use do_nasm or do_ms in this case.
897
898      OpenSSL >= 1.1.0
899
900      C:>cd openssl
901      C:>perl Configure VC-WIN32
902      C:>nmake
903      C:>nmake test
904      C:>cd ..
905
906      Apache 2
907
908      This step is only required for building the server dso modules.
909
910      ### FIXME Apache 2.2 or greater required. Old build instructions for VC6.
911
912      C:>set APACHEDIR=C:\Program Files\Apache Group\Apache2
913      C:>msdev httpd-2.0.58\apache.dsw /MAKE "BuildBin - Win32 Release"
914
915      APR
916
917      If you downloaded APR / APR-UTIL / APR_ICONV by source, you will have to
918      build these libraries first.
919      Building these libraries on Windows is straight forward and in most cases
920      as simple as issuing these two commands:
921
922      C:>nmake -f Makefile.win
923      C:>nmake -f Makefile.win install
924
925      Please refere to the build instructions provided by the library source
926      for actual build instructions.
927
928      ZLib
929
930      If you downloaded the zlib source, you will have to build ZLib first.
931      Building ZLib using Visual Studio should be quite simple. Just open the
932      appropriate solution and build the project zlibstat using the IDE.
933
934      Please refere to the build instructions provided by the library source
935      for actual build instructions.
936
937      Note that you'd make sure to define ZLIB_WINAPI in the ZLib config
938      header and move the lib-file into the zlib root-directory.
939
940      Apache Serf
941
942      ### Section about Apache Serf might be required/useful to add.
943      ### scons is required too and Apache Serf needs to be configured prior to
944      ### be able to build Subversion using:
945      ### scons APR=[PATH_TO_APR] APU=[PATH_TO_APU] OPENSSL=[PATH_TO_OPENSSL]
946      ### ZLIB=[PATH_TO_ZLIB] PREFIX=[PATH_TO_SERF_DEST]
947      ### scons check
948      ### scons install
949
950      Subversion
951
952      Things to note:
953
954      * If you don't want to build mod_dav_svn, omit the --with-httpd
955        option.  The zip file source distribution contains apr, apr-util and
956        apr-iconv in the default build location. If you have downloaded the
957        apr files yourself you will have to tell the generator where to find
958        the APR libraries; the options are --with-apr, --with-apr-util and
959        --with-apr-iconv.
960      * If you would like a debug build substitute Debug for Release in
961        the msbuild command.
962      * There have been rumors that Subversion on Win32 can be built
963        using the latest cygwin, you probably don't want the zip file source
964        distribution though. ymmv.
965      * You will also have to distribute the C runtime dll with the binaries.
966        Also, since Apache/APR do not provide .vcproj files, you will need to
967        convert the Apache/APR .dsp files to .vcproj files with Visual Studio
968        before building -- just open the Apache .dsw file and answer 'Yes To
969        All' when the conversion dialog pops up, or you can open the individual
970        .dsp files and convert them one at a time.
971        The Apache/APR projects required by Subversion are:
972        apr-util\libaprutil.dsp, apr\libapr.dsp,
973        apr-iconv\libapriconv.dsp, apr-util\xml\expat\lib\xml.dsp,
974        apr-iconv\ccs\libapriconv_ccs_modules.dsp, and
975        apr-iconv\ces\libapriconv_ces_modules.dsp.
976      * If the server dso modules are being built and tested Apache must not
977        be running or the copy of the dso modules will fail.
978
979      C:>cd src-%DIR%
980
981      If Apache 2 has been built and the server modules are required then
982      gen-make.py will already have been run. If the source is from the zip
983      file, Apache 2 has not been built so gen-make.py must be run:
984
985      C:>python gen-make.py --vsnet-version=20xx --with-berkeley-db=db4-win32
986          --with-openssl=..\openssl --with-zlib=..\zlib
987          --with-libintl=..\svn-win32-libintl
988
989      Then build subversion:
990
991      C:>msbuild subversion_vcnet.sln /t:__MORE__ /p:Configuration=Release
992      C:>cd ..
993
994      The binaries have now been built.
995
996  E.5 Packaging the binaries
997
998      You now need to copy the binaries ready to make the release zip
999      file. You also need to do this to run the tests as the new binaries
1000      need to be in your path. You can use the build/win32/make_dist.py
1001      script in the Subversion source directory to do that.
1002
1003      [TBD: Describe how to do this. Note dependencies on zip, jar, doxygen.]
1004
1005  E.6 Testing the Binaries
1006      [TBD: It's been a long, long while since it was necessary to move
1007            binaries around for testing. win-tests.py does that automagically.
1008            Fix this section accordingly, and probably reorder, putting
1009            the packaging at the end.]
1010
1011      The build process creates the binary test programs but it does not
1012      copy the client tests into the release test area.
1013
1014      C:>cd src-%DIR%
1015      C:>mkdir Release\subversion\tests\cmdline
1016      C:>xcopy /S /Y subversion\tests\cmdline Release\subversion\tests\cmdline
1017
1018      If the server dso modules  have been built then copy the dso files and
1019      dlls into the Apache modules directory.
1020
1021      C:>copy Release\subversion\mod_dav_svn\mod_dav_svn.so "%APACHEDIR%"\modules
1022      C:>copy Release\subversion\mod_authz_svn\mod_authz_svn.so
1023         "%APACHEDIR%"\modules
1024      C:>copy svn-win32-%VER%\bin\intl.dll "%APACHEDIR%\bin"
1025      C:>copy svn-win32-%VER%\bin\iconv.dll "%APACHEDIR%\bin"
1026      C:>copy svn-win32-%VER%\bin\libdb42.dll "%APACHEDIR%\bin"
1027      C:>cd ..
1028
1029      Put the svn-win32-trunk\bin directory at the start of your path so
1030      you run the newly built binaries and not another version you might
1031      have installed.
1032
1033      Then run the client tests:
1034
1035      C:>PATH=%BUILD_ROOT%\svn-win32-%VER%\bin;%PATH%
1036      C:>cd src-%DIR%
1037      C:>python win-tests.py -c -r -v
1038
1039      If the server dso modules were built configure Apache to use the
1040      mod_dav_svn and mod_authz_svn modules by making sure these lines appear
1041      uncommented in httpd.conf:
1042
1043        LoadModule dav_module         modules/mod_dav.so
1044        LoadModule dav_fs_module      modules/mod_dav_fs.so
1045        LoadModule dav_svn_module     modules/mod_dav_svn.so
1046        LoadModule authz_svn_module   modules/mod_authz_svn.so
1047
1048      And further down the file add location directives to point to the
1049      test repositories. Change the paths to the SVN directory you created
1050      (paths should be on one line even if wrapped here):
1051
1052        <Location /svn-test-work/repositories>
1053         DAV svn
1054         SVNParentPath C:/SVN/src-trunk/Release/subversion/tests/cmdline/
1055                       svn-test-work/repositories
1056        </Location>
1057
1058        <Location /svn-test-work/local_tmp/repos>
1059         DAV svn
1060         SVNPath c:/SVN/src-trunk/Release/subversion/tests/cmdline/
1061                 svn-test-work/local_tmp/repos
1062        </Location>
1063
1064      Then restart Apache and run the tests:
1065
1066      C:>python win-tests.py -c -r -v -u http://localhost
1067      C:>cd ..
1068
1069III.  BUILDING A SUBVERSION SERVER
1070      ============================
1071
1072      Subversion has two servers you can choose from:  svnserve and
1073      Apache.  svnserve is a small, lightweight server program that is
1074      automatically compiled when you build Subversion's source.  Apache
1075      is a more heavyweight HTTP server, but tends to have more features.
1076
1077      This section primarily focuses on how to build Apache and the
1078      accompanying mod_dav_svn server module for it.  If you plan to use
1079      svnserve instead, jump right to section E for a quick explanation.
1080
1081
1082  A.  Setting Up Apache Httpd
1083      -----------------------
1084
1085      1.  Obtaining and Installing Apache Httpd 2
1086
1087      Subversion tries to compile against the latest released version
1088      of Apache httpd 2.2+.  The easiest thing for you to do is download
1089      a source tarball of the latest release and unpack that.
1090
1091      If you have questions about the Apache httpd 2.2 build, please consult
1092      the httpd install documentation:
1093
1094          https://httpd.apache.org/docs-2.2/install.html
1095
1096      At the top of the httpd tree:
1097
1098          $ ./buildconf
1099          $ ./configure --enable-dav --enable-so --enable-maintainer-mode
1100
1101      The first arg says to build mod_dav.
1102
1103      The second arg says to enable shared module support which is needed
1104      for a typical compile of mod_dav_svn (see below).
1105
1106      The third arg says to include debugging information.  If you
1107      built Subversion with --enable-maintainer-mode, then you should
1108      do the same for Apache; there can be problems if one was
1109      compiled with debugging and the other without.
1110
1111      Note: if you have multiple db versions installed on your system,
1112      Apache might link to a different one than Subversion, causing
1113      failures when accessing the repository through Apache.  To prevent
1114      this from happening, you have to tell Apache which db version to
1115      use and where to find db.  Add --with-dbm=db4 and
1116      --with-berkeley-db=/usr/local/BerkeleyDB.4.2 to the configure
1117      line.  Make sure this is the same db as the one Subversion uses.
1118      This note assumes you have installed Berkeley DB 4.2.52
1119      at its default locations.  For more info about the db requirement,
1120      see section I.C.7.
1121
1122      You may also want to include other modules in your build. Add
1123      --enable-ssl to turn on SSL support, and --enable-deflate to turn on
1124      compression support, for example.  Consult the Apache documentation
1125      for more details.
1126
1127      All instructions below assume you configured Apache to install
1128      in its default location, /usr/local/apache2/; substitute
1129      appropriately if you chose some other location.
1130
1131      Compile and install apache:
1132
1133          $ make && make install
1134
1135
1136  B.  Making and Installing the Subversion Apache Server Module
1137      ---------------------------------------------------------
1138
1139      Go back into your subversion working copy and run ./autogen.sh if
1140      you need to.  Then, assuming Apache httpd 2.2 is installed in the
1141      standard location, run:
1142
1143          $ ./configure
1144
1145      Note: do *not* configure subversion with "--disable-shared"!
1146      mod_dav_svn *must* be built as a shared library, and it will
1147      look for other libsvn_*.so libraries on your system.
1148
1149      If you see a warning message that the build of mod_dav_svn is
1150      being skipped, this may be because you have Apache httpd 2.x
1151      installed in a non-standard location.  You can use the
1152      "--with-apxs=" option to locate the apxs script:
1153
1154          $ ./configure --with-apxs=/usr/local/apache2/bin/apxs
1155
1156      Note: it *is* possible to build mod_dav_svn as a static library
1157      and link it directly into Apache. Possible, but painful. Stick
1158      with the shared library for now; if you can't, then ask.
1159
1160          $ rm /usr/local/lib/libsvn*
1161
1162      If you have old subversion libraries sitting on your system,
1163      libtool will link them instead of the `fresh' ones in your tree.
1164      Remove them before building subversion.
1165
1166          $ make clean && make && make install
1167
1168      After the make install, the Subversion shared libraries are in
1169      /usr/local/lib/.  mod_dav_svn.so should be installed in
1170      /usr/local/libexec/ (or elsewhere, such as /usr/local/apache2/modules/,
1171      if you passed --with-apache-libexecdir to configure).
1172
1173
1174      Section II.E explains how to build the server on Windows.
1175
1176
1177  C.  Configuring Apache Httpd for Subversion
1178      ---------------------------------------
1179
1180      The following section is an abbreviated version of the
1181      information in the Subversion Book
1182      (http://svnbook.red-bean.com).  Please read chapter 6 for more
1183      details.
1184
1185      The following assumes you have already created a repository.
1186      For documentation on how to do that, see README.
1187
1188      The following also assumes that you have modified
1189      /usr/local/apache2/conf/httpd.conf to reflect your setup.
1190      At a minimum you should look at the User, Group and ServerName
1191      directives.  Full details on setting up apache can be found at:
1192      https://httpd.apache.org/docs-2.2/
1193
1194      First, your httpd.conf needs to load the mod_dav_svn module.
1195      If you pass --enable-mod-activation to Subversion's configure,
1196      'make install' target should automatically add this line for you.
1197      In any case, if Apache HTTPD gives you an error like "Unknown
1198      DAV provider: svn", then you may want to verify that this line
1199      exists in your httpd.conf:
1200
1201         LoadModule dav_svn_module     modules/mod_dav_svn.so
1202
1203      NOTE: if you built mod_dav as a dynamic module as well, make sure
1204      the above line appears after the one that loads mod_dav.so.
1205
1206      Next, add this to the *bottom* of your httpd.conf:
1207
1208      <Location /svn/repos>
1209          DAV svn
1210          SVNPath /absolute/path/to/repository
1211      </Location>
1212
1213      This will give anyone unrestricted access to the repository.  If
1214      you want limited access, read or write, you add these lines to
1215      the Location block:
1216
1217          AuthType Basic
1218          AuthName "Subversion repository"
1219          AuthUserFile /my/svn/user/passwd/file
1220
1221      And:
1222
1223          a) For a read/write restricted repository:
1224
1225             Require valid-user
1226
1227          b) For a write restricted repository:
1228
1229             <LimitExcept GET PROPFIND OPTIONS REPORT>
1230                 Require valid-user
1231             </LimitExcept>
1232
1233          c) For separate restricted read and write access:
1234
1235             AuthGroupFile /my/svn/group/file
1236
1237             <LimitExcept GET PROPFIND OPTIONS REPORT>
1238                 Require group svn_committers
1239             </LimitExcept>
1240
1241             <Limit GET PROPFIND OPTIONS REPORT>
1242                 Require group svn_committers
1243                 Require group svn_readers
1244             </Limit>
1245
1246      ### FIXME Tutorials section refers to old 2.0 docs
1247      These are only a few simple examples.  For a complete tutorial
1248      on Apache access control, please consider taking a look at the
1249      tutorials found under "Security" on the following page:
1250      https://httpd.apache.org/docs-2.0/misc/tutorials.html
1251
1252      In order for 'svn cp' to work (which is actually implemented as a
1253      DAV COPY command), mod_dav needs to be able to determine the
1254      hostname of the server.  A standard way of doing this is to use
1255      Apache's ServerName directive to set the server's hostname.  Edit
1256      your /usr/local/apache2/conf/httpd.conf to include:
1257
1258      ServerName svn.myserver.org
1259
1260      If you are using virtual hosting through Apache's NameVirtualHost
1261      directive, you may need to use the ServerAlias directive to specify
1262      additional names that your server is known by.
1263
1264      If you have configured mod_deflate to be in the server, you can enable
1265      compression support for your repository by adding the following line
1266      to your Location block:
1267
1268          SetOutputFilter DEFLATE
1269
1270
1271      NOTE: If you are unfamiliar with an Apache directive, or not exactly
1272      sure about what it does, don't hesitate to look it up in the
1273      documentation: https://httpd.apache.org/docs-2.2/mod/directives.html.
1274
1275      NOTE: Make sure that the user 'nobody' (or whatever UID the
1276      httpd process runs as) has permission to read and write the
1277      Berkeley DB files!  This is a very common problem.

1280  D.  Running and Testing
1281      -------------------
1282
1283      Fire up apache 2:
1284
1285          $ /usr/local/apache2/bin/apachectl stop
1286          $ /usr/local/apache2/bin/apachectl start
1287
1288      Check /usr/local/apache2/logs/error_log to make sure it started
1289      up okay.
1290
1291      Try doing a network checkout from the repository:
1292
1293          $ svn co http://localhost/svn/repos wc
1294
1295      The most common reason this might fail is permission problems
1296      reading the repository db files.  If the checkout fails, make
1297      sure that the httpd process has permission to read and write to
1298      the repository.  You can see all of mod_dav_svn's complaints in
1299      the Apache error logfile, /usr/local/apache2/logs/error_log.
1300
1301      To run the regression test suite for networked Subversion, see
1302      the instructions in subversion/tests/cmdline/README.
1303      For advice about tracing problems, see "Debugging the server" in
1304      https://subversion.apache.org/docs/community-guide/.
1305
1306
1307  E.  Alternative:  'svnserve' and ra_svn
1308      -----------------------------------
1309
1310      An alternative network layer is libsvn_ra_svn (on the client
1311      side) and the 'svnserve' process on the server.  This is a
1312      simple network layer that speaks a custom protocol over plain
1313      TCP (documented in libsvn_ra_svn/protocol):
1314
1315         $ svnserve -d     # becomes a background daemon
1316         $ svn checkout svn://localhost/usr/local/svn/repository
1317
1318      You can use the "-r" option to svnserve to set a logical root
1319      for repositories, and the "-R" option to restrict connections to
1320      read-only access.  ("Read-only" is a logical term here; svnserve
1321      still needs write access to the database in this mode, but will
1322      not allow commits or revprop changes.)
1323
1324      'svnserve' has built-in CRAM-MD5 authentication (so you can use
1325      non-system accounts), and can also be tunneled over SSH (so you
1326      can use existing system accounts).  It's also capable of using
1327      Cyrus SASL if libsasl2 is detected at ./configure time.  Please
1328      read chapter 6 in the Subversion Book
1329      (http://svnbook.red-bean.com) for details on these features.

1333IV.   PLATFORM-SPECIFIC ISSUES
1334      ========================
1335
1336  A.  Windows XP
1337      ----------
1338
1339      There is an error in the Windows XP TCP/IP stack which causes
1340      corruption in certain cases.  This problem is exposed only
1341      through ra_dav.
1342
1343      The root of the matter is caused by duplicating file handles
1344      between parent and child processes.  The httpd Apache group
1345      explains this a lot better:
1346
1347          https://www.apache.org/dist/httpd/binaries/win32/#xpbug
1348
1349      And there's an item about this in the Subversion FAQ:
1350
1351          https://subversion.apache.org/faq.html#windows-xp-server
1352
1353      The only known workaround for now is to update to Windows XP
1354      SP1 (or higher).
1355
1356
1357  B.  Mac OS X
1358      --------
1359
1360      [TBD: Describe BDB 4.0.x problem]
