svntest scripts                                           -*- Text -*-
===============

This set of scripts is designed to wrap execution of all of
Subversion's Makefile test targets (e.g. "check", "davcheck",
"svncheck", etc.).


Usage
=====

1) Read the INSTALL (http://svn.collab.net/repos/svn/trunk/INSTALL)
   file, especially the sections about bootstrapping from a tarball
   and getting the latest APR-0.9, APR-UTIL-0.9 and httpd-2.0 sources.
   Check out and compile the latest Subversion. You could easily run
   svntest.sh against APR/APR-UTIL 1.0 and HTTPD 2.1 branches, just 
   checkout corresponding repositories, and edit svntest-config.sh.

2) Copy the svntest scripts from trunk/tools/test-scripts/svntest to
   somewhere outside the repository.  Then read and modify
   svntest-config.sh to reflect your local installation.  The rest of
   these instructions assume you have done this, and that you are
   familiar with the $TEST_ROOT and $INST_DIR locations from
   svntest-config.sh.

3) In $TEST_ROOT, create one or more scripts that configure Subversion
   in different ways (e.g., configure.shared, configure.static).
   These scripts must be set executable (chmod +x).

   Although they live in $TEST_ROOT, these scripts will be invoked
   from a $TEST_ROOT/obj-<projname>, e.g., $TEST_ROOT/obj-apr-0.9,
   (for which the config script would be $TEST_ROOT/config.apr-0.9).

   See the examples/ directory next to this README for some examples
   of these config scripts.

   At the moment, svntest-rebuild.sh will only recognize shared and
   static build types, but you can easily change that. If you do, also
   change svntest.sh so that it tests all the different configurations.

4) Tailor ${TEST_ROOT}/$HTTPD_NAME.conf (e.g., httpd-2.0.conf) as
   necessary.  The easiest way to get a template for http-2.0.conf is
   to install Apache httpd once, take the installed conf/httpd.conf,
   and edit it.  Things you probably want to change are: 

      a) Listen 127.0.0.1:52080

      b) LoadModule dav_svn_module     modules/mod_dav_svn.so

      c) User YOUR_USERNAME
         Group YOUR_GROUPNAME

      d) ServerName localhost:52080

      e) Add a mod_dav_svn block:
    
           <IfModule mod_dav_svn.c>
              Include conf/mod_dav_svn.conf
           </IfModule>

      f) Copy ./mod_dav_svn.conf (i.e., the one in the same directory
         as this README) to ${TEST_ROOT}/mod_dav_svn.conf, and adjust
         it as necessary.

         The actual name of the used mod_dav_svn conf file is
         ${TEST_ROOT}/mod_dav_${SVN_NAME}.conf, which is
         mod_dav_svn.conf with default settings.

         Likwise, copy ./dav_svn.passwd to ${TEST_ROOT}/dav_svn.passwd.
         (You shouldn't need to adjust it.)

         If you want to run regression tests for 1.1.x or 1.2.x with
         the same svntest setup, you have to change the SVN_NAME
         variable, and generate two additional mod_dav_svn conf files:

           sed 's!/svn-test-work!!' mod_dav_svn.conf > mod_dav_svn_1.2.x.conf
           sed 's!/svn-test-work!!' mod_dav_svn.conf > mod_dav_svn_1.1.x.conf
        
         and set SVN_NAME=svn_1.2.x for 1.2.x, and SVN_NAME=svn_1.1.x
         for 1.1.x.

   Don't ever touch config files under $INST_DIR/$HTTPD_NAME/conf,
   they will be overwritten by the script.
   
5) Make sure your environment (e.g., LD_LIBRARY_PATH) is set correctly
   to find Berkeley DB, etc.

6) Test execution can be dramatically sped up by keeping Subversion
   test data on a RAM disk.  On a Linux system, add lines like the
   following in your /etc/fstab file:

   tmpfs  /home/YOUR_USERNAME/svn/obj-sh/subversion/tests  tmpfs  defaults,user,noauto,exec,size=64m
   tmpfs  /home/YOUR_USERNAME/svn/obj-st/subversion/tests  tmpfs  defaults,user,noauto,exec,size=64m

   The minimum required size for testing RAM disk is actually many
   times greater than shown above.  However, svntest will
   automatically flag your test targets for cleanup when using a
   ramdisk, which dramatically reduces the space requirement.

   To enable RAM disk usage by svntest, set RAMDISK=yes, and check
   mount_ramdisk and umount_ramdisk in the svntest-config.sh file if
   your system is not GNU/Linux.  See
   http://subversion.tigris.org/faq.html#ramdisk-tests for further
   information.
   
7) Run svntest.sh to get the latest versions of APR, APR-UTIL, HTTPPD and
   Subversion, build and test all the configurations. 

8) If you like force rebuilding of some component, you could do:
   echo "0" > $<PROJ>_SOURCE.rb, dependencies are:
   apr-util depends on apr, and httpd depends on apr and apr-util.
   Any dependent project will be also rebuild.
   When you run this script first time, everything will be rebuilt 
   automatically.
