Annotation of cvsweb/INSTALL, Revision 3.29

3.3       knu         1: $FreeBSD$
3.2       knu         2:
3.29    ! scop        3: For notes on upgrading between FreeBSD-CVSweb releases, see the bottom
        !             4: of this document.
3.17      scop        5:
3.16      scop        6: 1) To get cvsweb.cgi to work, make sure that you have Perl 5.6.0 or
3.7       scop        7:    newer installed and a web server which is capable of executing CGI
3.18      scop        8:    scripts.  See also samples/cvsweb-httpd.conf.
3.7       scop        9:
3.10      scop       10:    CVSweb uses the following Perl modules.  Chances are that some of
3.7       scop       11:    these are already installed with your Perl distribution.  The oldest
                     12:    Perl distributions, if any, that already ship with these modules have
                     13:    been marked below.  If your Perl doesn't have some of the modules,
                     14:    you can get them from CPAN, <http://www.cpan.org/>.  Be sure to
                     15:    install also the prerequisites these modules may have.  Note that
                     16:    this list contains only modules that aren't already part of Perl
3.16      scop       17:    5.6.0 and newer.
3.17      scop       18:
3.7       scop       19:
3.11      scop       20:       Module                Version  Ships with Perl      Type
                     21:       ----------------------------------------------------------
                     22:       File::Temp                          5.8.0         required
3.12      scop       23:       IPC::Run                              N/A         required
3.11      scop       24:       MIME::Types                           N/A         optional
3.13      scop       25:       String::Ediff                         N/A         optional
3.15      scop       26:       URI                                   N/A         required
3.1       knu        27:
3.4       scop       28:    Surprisingly enough, you need to have cvs installed.  The recommended
                     29:    version of cvs is 1.11 or newer.  Older cvs versions may work with
                     30:    more or less quirks, YMMV.
                     31:
                     32:    Currently, you'll also need to have the GNU RCS utilities  'rlog',
3.17      scop       33:    'rcsdiff' installed (current version is 5.7).
3.1       knu        34:
3.6       scop       35:    This may change if cvs will be able to serve these functions without
                     36:    having a working directory [see TODO].
3.1       knu        37:
3.6       scop       38:    Note that the cvsweb.cgi script needs to have physical access to the
                     39:    repository (or a copy of it) therefore; rsh, ssh or pserver access
                     40:    doesn't work yet.
                     41:
3.20      scop       42:    Install CvsGraph if you want to use it with CVSweb, and see (6) for
3.8       scop       43:    configuration notes.  CvsGraph 1.4.0 or newer is required.
3.5       scop       44:
3.9       scop       45:    Install GNU Enscript if you want syntax highlighting, and see (7) for
3.19      scop       46:    more info.  You'll need version 1.6.3 or newer.
3.9       scop       47:
3.29    ! scop       48:    Install CVSHistory if you want to use it with CVSweb, and see (8) for
        !            49:    configuration notes.  You'll need version 2.0 or newer.
        !            50:
3.17      scop       51: 2) Copy cvsweb.conf to a configuration directory, typically
                     52:    /usr/local/etc/cvsweb/cvsweb.conf.
                     53:    Edit cvsweb.conf to fit your needs, you'll probably need to tweak the
                     54:    CVS root(s) of the Repository(ies) you want to view.
3.26      scop       55:    See also the @command_path variable for the path where cvsweb.cgi
3.17      scop       56:    looks for the various external executables it interacts with.
3.26      scop       57:    The other cvsweb.conf-* files are example per-cvsroot configuration files,
                     58:    see commentary in cvsweb.conf for more information.
3.17      scop       59:
                     60: 3) Copy cvsweb.cgi to a directory of your web server where the execution
                     61:    of CGI scripts is allowed.  Edit it to make the variable $config
                     62:    (look for 'Configuration Area') point to your configuration file.
3.4       scop       63:    If your perl binary isn't located in /usr/bin you'll have to edit the
3.26      scop       64:    first line of the script as well.  For Apache web servers, there is an
                     65:    optional sample httpd.conf snippet in the samples/ directory.  Most
                     66:    setups do not need it though, it is only for advanced and/or mod_perl
                     67:    configurations.
3.1       knu        68:
3.4       scop       69: 4) If you do not have the dir.gif, text.gif and back.gif icons, copy
                     70:    them somewhere in your $DocumentRoot and edit the %ICONS hash
                     71:    in cvsweb.conf.  You won't need to do this if you have a stock
                     72:    Apache installed - they're located in the default icons directory.
3.1       knu        73:    The icons distributed with this cvsweb are in the public domain.
3.4       scop       74:    If you think that the default icons are too large, use the corresponding
                     75:    mini icons in the icons/ directory and change the %ICONS hash in
3.1       knu        76:    cvsweb.conf.
                     77:
3.6       scop       78: 5) Copy cvsweb.css from the css/ directory to a web server directory, and
                     79:    point the $cssurl variable in cvsweb.conf to it.
                     80:
                     81: 6) CvsGraph <http://www.akhphd.au.dk/~bertho/cvsgraph/> can be used with
3.20      scop       82:    this version of CVSweb.  See the $allow_cvsgraph and $cvsgraph_config
3.28      scop       83:    configuration variables in cvsweb.conf.  Note (and install) also the
                     84:    cvsgraph.png icon in the icons/ directory.
3.5       scop       85:
3.9       scop       86: 7) GNU Enscript <http://www.iki.fi/~mtr/genscript/> can be used for syntax
3.27      scop       87:    highlighting.  To enable it, copy lang_cvsweb.st and lang_cvsweb_diff.st
                     88:    from the enscript/ dir to your Enscript "hl" directory (often eg.
                     89:    /usr/share/enscript/hl/) and enable $allow_enscript in cvsweb.conf.
                     90:    lang_cvsweb.st is used for generic colorization, and lang_cvsweb_diff.st
                     91:    for diffs.
3.9       scop       92:
3.29    ! scop       93: 8) CVSHistory <http://www.jamwt.com/CVSHistory/> can be used with this
        !            94:    version of CVSweb.  See the $cvshistory_url configuration variable in
        !            95:    cvsweb.conf.  For best results, configure CVSweb and CVSHistory to use
        !            96:    the same "logical names" for CVS roots.
3.1       knu        97:
3.17      scop       98: 9) If you like you can add descriptions to be shown next to each directory
3.4       scop       99:    or module name.  These are read from CVSROOT/descriptions.
3.1       knu       100:
                    101:    - Check out a copy of your CVSROOT
                    102:    - edit checkoutlist and add a line that says
                    103:        descriptions
3.17      scop      104:    - Edit descriptions.  Add one line for each directory that you would like
3.1       knu       105:      to have a comment for.  You can have HTML in the descriptions.
                    106:      These lines are relative from the $CVSROOT.  Example:
3.22      scop      107:        JVote          An application to assist with <a href="http://www.irtc.org/">IRTC</a> voting
3.3       knu       108:        JVote/images   Store the images for JVote
                    109:        JVote/tools    Scripts to startup JVote
3.1       knu       110:    - cvs add descriptions
                    111:    - cvs commit
                    112:    - Set $use_descriptions to 1 in cvsweb.conf.
                    113:
3.29    ! scop      114: 10) Have fun!

3.17      scop      116: Troubleshooting
                    117: ---------------
3.1       knu       118:
                    119: If you've trouble to make cvsweb.cgi work ...
                    120: .. if nothing seems to work:
3.17      scop      121:  o Check if you can execute CGI scripts (Apache needs to have an
                    122:    ScriptAlias /cgi-bin or cgi-script Handler defined).  Try to
3.4       scop      123:    execute a simple CGI script that often comes with the distribution
                    124:    of the web server; locate the log files and try to find hints
                    125:    which explain the malfunction.
3.17      scop      126: o  View the entries in the web server's error.log.
3.1       knu       127:
                    128: .. If cvsweb seems to work but doesn't show the expected result
                    129:   (Typical error: you can't see any files)
3.4       scop      130:  o Check whether the CGI script has read permissions to your
3.17      scop      131:    CVS repository.  The CGI script often runs as the user 'nobody'
                    132:    or 'httpd'.
                    133:  o If you use annotation, see @annotate_options in cvsweb.conf.
                    134:  o See CVSROOT/config for various options controlling what gets written
                    135:    into CVSROOT/history, where lock files are placed etc.  You can also
                    136:    build a fake cvsroot with symlinks to the 'real' CVS directories and make
3.1       knu       137:    a fake CVSROOT/history as symbolic link to /dev/null.
3.17      scop      138:    If you don't want cvs called from cvsweb to place read locks at all, let
3.1       knu       139:    cvsweb operate on a copy.
3.17      scop      140:  o Does cvsweb find your RCS utils/cvs binary(annotate)?
                    141:    See $command_path in in cvsweb.conf.
                    142:  o cvsweb allows for compression now.  It is determined first if the
                    143:    browser accepts gzip encoding.  But - no rule without exception - some
                    144:    versions of MSIE claim to understand gzip encoded content but
                    145:    display garbage .. so compression for MSIE is disabled now.  Maybe you
                    146:    find another browser with this problem, then you should disable
                    147:    compression ($allow_compress=0 in cvsweb.conf) and report it to
                    148:    <freebsd-cvsweb@freebsd.org>.

                    165:
3.25      scop      166:    @HideModules has been removed.  It had nothing to do with actual
                    167:    modules in CVS terminology, and the implementation was broken.
                    168:    @ForbiddenFiles has been enhanced to affect directories as well.
                    169:

3.17      scop      176:
                    177:    %DEFAULTVALUE for "ln" can now be set to a boolean indicating whether
                    178:    line numbers in markup views should be shown or not.  The default is off.
                    179:
