See also samples/cvsweb-httpd.conf. CVSweb uses the following Perl modules. Chances are that some of these are already installed with your Perl distribution. The oldest Perl distributions, if any, that already ship with these modules have been marked below. If your Perl doesn't have some of the modules, you can get them from CPAN, . Be sure to install also the prerequisites these modules may have. Note that this list contains only modules that aren't already part of Perl 5.6.0 and newer. Module Version Ships with Perl Type ---------------------------------------------------------- File::Temp 5.8.0 required IPC::Run N/A required MIME::Types N/A optional URI N/A required Surprisingly enough, you need to have cvs installed. The recommended version of cvs is 1.11 or newer. Older cvs versions may work with more or less quirks, YMMV. Currently, you'll also need to have the GNU RCS utilities 'rlog', 'rcsdiff' installed (current version is 5.7). This may change if cvs will be able to serve these functions without having a working directory [see TODO]. Note that the cvsweb.cgi script needs to have physical access to the repository (or a copy of it) therefore; rsh, ssh or pserver access doesn't work yet. 2) Copy cvsweb.conf to a configuration directory, typically /usr/local/etc/cvsweb/cvsweb.conf. Edit cvsweb.conf to fit your needs, you'll probably need to tweak the CVS root(s) of the Repository(ies) you want to view. See also the @command_path variable for the path where cvsweb.cgi looks for the various external executables it interacts with. The other cvsweb.conf-* files are example per-cvsroot configuration files, see commentary in cvsweb.conf for more information. 3) Copy cvsweb.cgi to a directory of your web server where the execution of CGI scripts is allowed. Edit it to make the variable $config (look for 'Configuration Area') point to your configuration file. If your perl binary isn't located in /usr/bin you'll have to edit the first line of the script as well. For Apache web servers, there is an optional sample httpd.conf snippet in the samples/ directory. Most setups do not need it though, it is only for advanced and/or mod_perl configurations. 4) If you do not have the dir.gif, text.gif and back.gif icons, copy them somewhere in your $DocumentRoot and edit the %ICONS hash in cvsweb.conf. You won't need to do this if you have a stock Apache installed - they're located in the default icons directory. The icons distributed with this cvsweb are in the public domain. If you think that the default icons are too large, use the corresponding mini icons in the icons/ directory and change the %ICONS hash in cvsweb.conf. 5) Copy cvsweb.css from the css/ directory to a web server directory, and point the $cssurl variable in cvsweb.conf to it. 9) If you like you can add descriptions to be shown next to each directory or module name. These are read from CVSROOT/descriptions. - Check out a copy of your CVSROOT - edit checkoutlist and add a line that says descriptions - Edit descriptions. Add one line for each directory that you would like to have a comment for. You can have HTML in the descriptions. These lines are relative from the $CVSROOT. Example: JVote An application to assist with IRTC voting JVote/images Store the images for JVote JVote/tools Scripts to startup JVote - cvs add descriptions - cvs commit - Set $use_descriptions to 1 in cvsweb.conf. 10) Have fun! Troubleshooting --------------- If you've trouble to make cvsweb.cgi work ... .. if nothing seems to work: o Check if you can execute CGI scripts (Apache needs to have an ScriptAlias /cgi-bin or cgi-script Handler defined). Try to execute a simple CGI script that often comes with the distribution of the web server; locate the log files and try to find hints which explain the malfunction. o View the entries in the web server's error.log. Set $DEBUG to 1 in cvsweb.conf to get more error output. .. If cvsweb seems to work but doesn't show the expected result (Typical error: you can't see any files) o Check whether the CGI script has read permissions to your CVS repository. The CGI script often runs as the user 'nobody' or 'httpd'. o If you use annotation, see @annotate_options in cvsweb.conf. o See CVSROOT/config for various options controlling what gets written into CVSROOT/history, where lock files are placed etc. You can also build a fake cvsroot with symlinks to the 'real' CVS directories and make a fake CVSROOT/history as symbolic link to /dev/null. If you don't want cvs called from cvsweb to place read locks at all, let cvsweb operate on a copy. o Does cvsweb find your RCS utils/cvs binary(annotate)? See $command_path in in cvsweb.conf. o cvsweb allows for compression now. It is determined first if the browser accepts gzip encoding. But - no rule without exception - some versions of MSIE claim to understand gzip encoded content but display garbage .. so compression for MSIE is disabled now. Maybe you find another browser with this problem, then you should disable compression ($allow_compress=0 in cvsweb.conf). Upgrade instructions -------------------- List of things to pay attention to when upgrading CVSweb from earlier versions follows. Lack of instructions for a particular version means that there are no special things to pay attention to. Upgrading to 3.0.5 ------------------ The following configuration variables in cvsweb.conf have changed: $allow_mailtos is new, and optional. See comments in cvsweb.conf. Upgrading to 3.0.3 ------------------ The following configuration variables in cvsweb.conf have changed: $DEBUG is new, and optional. See comments in cvsweb.conf. Upgrading to 3.0.0 ------------------ Make sure that the dependencies are met, see 1) above. The following configuration variables in cvsweb.conf have changed: $command_path has been changed to @command_path, ie. a list. @HideModules has been removed. It had nothing to do with actual modules in CVS terminology, and the implementation was broken. @ForbiddenFiles has been enhanced to affect directories as well. $cvstreedefault is now optional. If unset, the first one in @CVSrepositories is used. %DEFAULTVALUE for "ln" can now be set to a boolean indicating whether line numbers in markup views should be shown or not. The default is off. The following parameters have been removed, use CSS instead: $body_tag, $body_tag_for_src, $navigationHeaderColor, $dirtable, @tabcolors, $columnHeaderColorDefault, $columnHeaderColorSorted, $tableBorderColor, $diffcolorHeading, $diffcolorEmpty, $diffcolorRemove, $diffcolorChange, $diffcolorAdd, $diffcolorDarkChange, $difffontface, $difffontsize, $markupLogColor. The following parameters have been removed, with no replacement: $open_extern_window, $extern_window_height, $extern_window_width, $checkout_magic. $file_list_len can be set to work around problems with rlog(1) and dirs with lots of files. $cssurl contains the absolute URI to the CSS file to use. %ICONS has a new entry: binfile for binary files (-kb keyword substitution). %DIFF_COMMANDS is new, it is used to configure external per file type diff commands.
