Quick sanity check:
If you just want to see what your repository looks like when seen
through ViewVC, type:
$ bin/standalone.py -r /PATH/TO/REPOSITORY
This will start a tiny ViewVC server at http://localhost:49152/viewvc/,
to which you can connect with your browser.
If you just want to see what your CVS repository looks like with
ViewCVS, type "./standalone.py -g -r /PATH/TO/CVS/ROOT". This
will start a tiny webserver serving at http://localhost:7467/.
Standard operation:
To start installing right away (on UNIX): type "./viewvc-install"

SECURITY INFORMATION
--------------------
ViewVC provides a feature which allows version controlled content to
be served to web browsers just like static web server content. So, if
you have a directory full of interrelated HTML files that is housed in
your version control repository, ViewVC can serve those files as HTML.
You'll see in your web browser what you'd see if the files were part
of your website, with working references to stylesheets and images and
links to other pages.
It is important to realize, however, that as useful as that feature
is, there is some risk security-wise in its use. Essentially, anyone
with commit access to the CVS or Subversion repositories served by
ViewVC has the ability to affect site content. If a discontented or
ignorant user commits malicious HTML to a version controlled file
(perhaps just by way of documenting examples of such), that malicious
HTML is effectively published and live on your ViewVC instance.
Visitors viewing those versioned controlled documents get the
malicious code, too, which might not be what the original author
intended.
For this reason, ViewVC's "checkout" view is disabled by default. If
you wish to enable it, simply add "co" to the list of views enabled in
the allowed_views configuration option.
INSTALLING VIEWVC
INSTALLING VIEWCVS
------------------
NOTE: Windows users can refer to windows/README for Windows-specific
installation instructions.
1) To get viewcvs.cgi to work, make sure that you have Python 1.5 or
greater installed and a webserver which is capable of executing
CGI scripts (either based on the .cgi extension, or by placing the
script within a specific directory).
1) To get viewvc.cgi to work, make sure that you have Python installed
and a webserver which is capable of executing CGI scripts (either

You need to have RCS installed. Specifically, "rlog", "rcsdiff",
and "co". This script was tested against RedHat's rcs-5.7-10.rpm
Note that to browse CVS repositories, the viewvc.cgi script needs to
have READ-ONLY, physical access to the repository (or a copy of it).
Therefore, rsh/ssh or pserver access to the repository will not work.

2) Installation is handled by the ./viewvc-install script. Run this
For the more human readable diff formats you need a modern diff utility.
If you are using Linux, this is no problem. But on commercial unices
you might want to install GNU-diff to be able to use unified or
side-by-side diffs.
If you want to use cvsgraph, you have to obtain and install this
separately. See below. This was tested with cvsgraph-1.1.2.
For the checkin database to work, you will need MySQL >= 3.22,
and the Python DBAPI 2.0 module, MySQLdb. This was tested with
MySQLdb 0.9.1.
2) Installation is handled by the ./viewcvs-install script. Run this
script and you will be prompted for a installation root path.
The default is /usr/local/viewvc-VERSION, where VERSION is
the version of this ViewVC release. The installer sets the install

That's it for repository browsing. Instructions for getting the SQL

5) That's it for repository browsing. Instructions for getting the
SQL checkin database working are below.
APACHE CONFIGURATION
--------------------
1) Locate your Apache configuration file(s).
Typical locations are /etc/httpd/httpd.conf,
/etc/httpd/conf/httpd.conf, and /etc/apache/httpd.conf. Depending
on how Apache was installed, you may also look under /usr/local/etc
or /etc/local. Use the vendor documentation or the find utility if
in doubt.
2) Depending on how your Apache configuration is setup by default, you
might need to explicitly allow high-level access to the ViewVC
install location.
<Directory <VIEWVC_INSTALLATION_DIRECTORY>>
Order allow,deny
Allow from all
</Directory>
For example, if ViewVC is installed in /usr/local/viewvc-1.0 on
your system:
<Directory /usr/local/viewvc-1.0>
Order allow,deny
Allow from all
</Directory>
3) Configure Apache to expose ViewVC to users at the URL of your choice.
ViewVC provides several different ways to do this. Choose one of
the following methods:
-----------------------------------
METHOD A: CGI mode via ScriptAlias
-----------------------------------
The ScriptAlias directive is very useful for pointing
directly to the viewvc.cgi script. Simply insert a line containing
ScriptAlias /viewvc <VIEWVC_INSTALLATION_DIRECTORY>/bin/cgi/viewvc.cgi
into your httpd.conf file. Choose the location in httpd.conf where
also the other ScriptAlias lines reside. Some examples:
ScriptAlias /viewvc /usr/local/viewvc-1.0/bin/cgi/viewvc.cgi
ScriptAlias /query /usr/local/viewvc-1.0/bin/cgi/query.cgi
----------------------------------------
METHOD B: CGI mode in cgi-bin directory
----------------------------------------
Copy the CGI scripts from
<VIEWVC_INSTALLATION_DIRECTORY>/bin/cgi/*.cgi
to the /cgi-bin/ directory configured in your httpd.conf file.
You can override configuration file location using:
SetEnv VIEWVC_CONF_PATHNAME /etc/viewvc.conf
------------------------------------------
METHOD C: CGI mode in ExecCGI'd directory
------------------------------------------
Copy the CGI scripts from
<VIEWVC_INSTALLATION_DIRECTORY>/bin/cgi/*.cgi
to the directory of your choosing in the Document Root adding the following
Apache directives for the directory in httpd.conf or an .htaccess file:
Options +ExecCGI
AddHandler cgi-script .cgi
Note: For this to work mod_cgi has to be loaded. And for the .htaccess file
to be effective, "AllowOverride All" or "AllowOverride Options FileInfo"
needs to have been specified for the directory.
------------------------------------------
METHOD D: Using mod_python (if installed)
------------------------------------------
Copy the Python scripts and .htaccess file from
<VIEWVC_INSTALLATION_DIRECTORY>/bin/mod_python/
to a directory being served by Apache.
In httpd.conf, make sure that "AllowOverride All" or at least
"AllowOverride FileInfo Options" are enabled for the directory
you copied the files to.
You can override configuration file location using:
SetEnv VIEWVC_CONF_PATHNAME /etc/viewvc.conf
Note: If you are using Mod_Python under Apache 1.3 the tarball generation
feature may not work because it uses multithreading. This works fine
under Apache 2.
----------------------------------------
METHOD E: Using mod_wsgi (if installed)
----------------------------------------
Copy the Python scripts file from
<VIEWVC_INSTALLATION_DIRECTORY>/bin/wsgi/
to the directory of your choosing. Modify httpd.conf with the
following directives:
WSGIScriptAlias /viewvc <VIEWVC_INSTALLATION_DIRECTORY>/bin/wsgi/viewvc.wsgi
WSGIScriptAlias /query <VIEWVC_INSTALLATION_DIRECTORY>/bin/wsgi/query.wsgi
You'll probably also need the following directive because of the
not-quite-sanctioned way that ViewVC manipulates Python objects.
WSGIApplicationGroup %{GLOBAL}
Note: WSGI support in ViewVC is at this time quite rudimentary,
bordering on downright experimental. Your mileage may vary.
-----------------------------------------
METHOD F: Using mod_fcgid (if installed)
-----------------------------------------
This uses ViewVC's WSGI support (from above), but supports using FastCGI,
and is a somewhat hybrid approach of several of the above methods.
Especially if fcgi is already being used for other purposes, e.g. PHP,
also using fcgi can prevent the need for including additional modules
(e.g. mod_python or mod_wsgi) within Apache, which may help lessen Apache's
memory usage and/or help improve performance.
This depends on mod_fcgid:
http://httpd.apache.org/mod_fcgid/
as well as the fcgi server from Python's flup package:
http://pypi.python.org/pypi/flup
http://trac.saddi.com/flup
The following are some example httpd.conf fragments you can use to
support this configuration:
ScriptAlias /viewvc /usr/local/viewvc/bin/wsgi/viewvc.fcgi
ScriptAlias /query /usr/local/viewvc/bin/wsgi/query.fcgi
4) [Optional] Provide direct access to icons, stylesheets, etc.
ViewVC's HTML templates reference various stylesheets and icons
provided by ViewVC itself. By default, ViewVC generates URLs to
those artifacts which point back into ViewVC (using a magic
syntax); ViewVC in turn handles such magic URL requests by
streaming back the contents of the requested icon or stylesheet
file. While this simplifies the configuration and initial
deployment of ViewVC, it's not the most efficient approach to
deliver what is essentially static content.
To improve performance, consider carving out a URL space in your
webserver's configuration solely for this static content and
instruct ViewVC to use that space when generating URLs for that
content. For example, you might add an Alias such as the following
to your httpd.conf:
Alias /viewvc-docroot /usr/local/viewvc/templates/default/docroot
And then, in viewvc.conf, set the 'docroot' option to the same
location:
docroot = /viewvc-docroot
WARNING: As always when using Alias directives, be careful that you
have them in the correct order. For example, if you use an
ordering such as the following, Apache will hand requests for your
static documents off to ViewVC as if they were versioned resources:
ScriptAlias /viewvc /usr/local/viewvc/bin/wsgi/viewvc.fcgi
Alias /viewvc/static /usr/local/viewvc/templates/default/docroot
The correct order would be:
Alias /viewvc/static /usr/local/viewvc/templates/default/docroot
ScriptAlias /viewvc /usr/local/viewvc/bin/wsgi/viewvc.fcgi
(That said, it's best to avoid such namespace nesting altogether if
you can.)
5) [Optional] Add access control.
In your httpd.conf you can control access to certain modules by
adding directives like this:
<Location "<url to viewvc.cgi>/<modname_you_wish_to_access_ctl>">
AllowOverride None
AuthUserFile /path/to/passwd/file
AuthName "Client Access"
AuthType Basic
require valid-user
</Location>
WARNING: If you enable the "checkout_magic" or "allow_tar" options, you
will need to add additional location directives to prevent people
from sneaking in with URLs like:
http://<server_name>/viewvc/*checkout*/<module_name>
http://<server_name>/viewvc/~checkout~/<module_name>
http://<server_name>/viewvc/<module_name>.tar.gz?view=tar
6) Restart Apache.
The commands to do this vary. "httpd -k restart" and "apache -k
restart" are two common variants. On RedHat Linux it is done using
the command "/sbin/service httpd restart" and on SuSE Linux it is
done with "rcapache restart". Other systems use "apachectl restart".
7) [Optional] Protect your ViewVC instance from server-whacking webcrawlers.
As ViewVC is a web-based application which each page containing various
links to other pages and views, you can expect your server's performance
to suffer if a webcrawler finds your ViewVC instance and begins
traversing those links. We highly recommend that you add your ViewVC
location to a site-wide robots.txt file. Visit the Wikipedia page
for Robots.txt (http://en.wikipedia.org/wiki/Robots.txt) for more
information.
WARNING: ViewCVS has not been tested on web servers operating on the
Win32 platform.

Various queries can be performed on the database. After installing ViewVC,
Various queries can be performed on the database. After installing ViewCVS,
there are some additional steps required to get the database working.
1) You need MySQL and MySQLdb (a Python DBAPI 2.0 module) installed.
1) You need MySQL >= 3.22, and the Python module MySQLdb 0.9.0 installed.
Python 1.5.2 is REQUIRED by MySQLdb, therefore to use this part of
ViewCVS you must be using Python 1.5.2. Additionally you will need the
mxDateTime extension. I've tested with version 1.3.0
2) You need to create a MySQL user who has permission to create databases.
Optionally, you can create a second user with read-only access to the
database.
3) Run the <VIEWVC_INSTALLATION_DIRECTORY>/bin/make-database script. It will

existing ViewCVS database, you will lose all your data!
4) Edit your <VIEWVC_INSTALLATION_DIRECTORY>/viewvc.conf file.
4) Edit your <VIEWCVS_INSTALLATION_DIRECTORY>/viewcvs.conf file.
There is a [cvsdb] section. You will need to set:
enabled = 1 # Whether to enable query support in viewvc.cgi
host = # MySQL database server host
port = # MySQL database server port (default is 3306)
database_name = # name of database you created with make-database
user = # read/write database user
passwd = # password for read/write database user
readonly_user = # read-only database user
readonly_passwd = # password for the read-only user
Note that it's pretty safe in this instance for your read-only user
and your read-write user to be the same.
5) At this point, you need to tell your version control system(s) to
publish their commit information to the database. This is done
using utilities that ViewVC provides.
To publish CVS commits into the database:
Two programs are provided for updating the checkin database from
a CVS repository, cvsdbadmin and loginfo-handler. They serve
two different purposes. The cvsdbadmin program walks through
your CVS repository and adds every commit in every file. This
is commonly used for initializing the database from a repository
which has been in use. The loginfo-handler script is executed
by the CVS server's CVSROOT/loginfo system upon each commit. It
makes real-time updates to the checkin database as commits are
made to the repository.
To build a database of all the commits in the CVS repository
/home/cvs, invoke: "./cvsdbadmin rebuild /home/cvs". If you
want to update the checkin database, invoke: "./cvsdbadmin
update /home/cvs". The update mode checks to see if a commit is
already in the database, and only adds it if it is absent.
To get real-time updates, you'll want to checkout the CVSROOT
module from your CVS repository and edit CVSROOT/loginfo. For
folks running CVS 1.12 or better, add this line:
ALL <VIEWVC_INSTALLATION_DIRECTORY>/bin/loginfo-handler %p %{sVv}
If you are running CVS 1.11 or earlier, you'll want a slightly
different command line in CVSROOT/loginfo:
ALL <VIEWVC_INSTALLATION_DIRECTORY>/bin/loginfo-handler %{sVv}
If you have other scripts invoked by CVSROOT/loginfo, you will
want to make sure to change any running under the "DEFAULT"
keyword to "ALL" like the loginfo handler, and probably
carefully read the execution rules for CVSROOT/loginfo from the
CVS manual.
If you are running the Unix port of CVS-NT, the handler script
need to know about it. CVS-NT delivers commit information to
loginfo scripts differently than the way mainstream CVS does.
Your command line should look like this:
ALL <VIEWVC_INSTALLATION_DIRECTORY>/bin/loginfo-handler %{sVv} cvsnt
host = # MySQL database server host
database_name = # the name of the database you created with
# make-database
user = # the read/write database user
passwd = # password for read/write database user
readonly_user = # the readonly database user -- it's pretty
# safe to use the read/write user here
readonly_passwd = # password for the readonly user
To publish Subversion commits into the database:
To build a database of all the commits in the Subversion
repository /home/svn, invoke: "./svndbadmin rebuild /home/svn".
If you want to update the checkin database, invoke:
"./svndbadmin update /home/svn".
To get real time updates, you will need to add a post-commit
hook (for the repository example above, the script should go in
/home/svn/hooks/post-commit). The script should look something
like this:
#!/bin/sh
REPOS="$1"
REV="$2"
<VIEWVC_INSTALLATION_DIRECTORY>/bin/svndbadmin update \
"$REPOS" "$REV"
If you allow revision property changes in your repository,
create a post-revprop-change hook script which uses the same
'svndbadmin update' command as the post-commit script, except
with the addition of the --force option:
#!/bin/sh
REPOS="$1"
REV="$2"
<VIEWVC_INSTALLATION_DIRECTORY>/bin/svndbadmin update --force \
"$REPOS" "$REV"
This will make sure that the checkin database stays consistent
when you change the svn:log, svn:author or svn:date revision
properties.
5) Two programs are provided for updating the checkin database,
cvsdbadmin and loginfo-handler. They serve two different purposes.
The cvsdbadmin program walks through your CVS repository and adds
every commit in every file. This is commonly used for initializing
the database from a repository which has been in use. The
loginfo-handler script is executed by the CVS server's CVSROOT/loginfo
system upon each commit. It makes real-time updates to the checkin
database as commits are made to the repository.
You should be ready to go. Click one of the "Query revision history"
links in ViewVC directory listings and give it a try.
To build a database of all the commits in the CVS repository /home/cvs,
invoke: "./cvsdbadmin rebuild /home/cvs". If you want to update
the checkin database, invoke: "./cvsdbadmin update /home/cvs". The
update mode checks to see if a commit is already in the database,
and only adds it if it is absent.
To get real-time updates, you'll want to checkout the CVSROOT module
from your CVS repository and edit CVSROOT/loginfo. Add the line:
ALL (echo %{sVv}; cat) | <VIEWCVS_INSTALLATION_DIRECTORY>/loginfo-handler
If you have other scripts invoked by CVSROOT/loginfo, you will want
to make sure to change any running under the "DEFAULT" keyword to
"ALL" like the loginfo handler, and probably carefully read the
execution rules for CVSROOT/loginfo from the CVS manual.
6) You may want to modify the HTML template file:
<VIEWCVS_INSTALLATION_DIRECTORY>/templates/query.ezt
This is used by the query.cgi script to generate part of its HTML output.
At some point the currently hardcoded table output will also vanish.
7) You should be ready to go. Load up the query.cgi script and give
it a try.
ENABLING SYNTAX COLORATION
--------------------------
ENSCRIPT CONFIGURATION
----------------------
ViewVC uses Pygments (http://pygments.org) for syntax coloration. You
need only install a suitable version of that module, and if ViewVC
finds it in your Python module path, it will use it (unless you
specifically disable the feature by setting use_pygments = 0 in your
viewvc.conf file).
Enscript is program that can colorize sourcecode of a lot of languages.
Linux distributions like for example SuSE Linux from at least 7.0
up to the recently released 7.3 already contain a precompiled and
configured enscript 1.6.2 package.
1) Download genscript from http://people.ssh.com/mtr/genscript/
2) Configure and compile per instructions with enscript.
(I 've not done this, since I'm using the precompiled package
delivered with SuSE Linux)
3) Set the 'use_enscript' option in viewcvs.conf to 1.
4) That's it!
5) If you want to colorize exotic languages, you might have to
patch 'lib/viewcvs.py' and add a new highlighting file to enscript.
I've done this for Modula-2 and submitted the file to the
enscript maintainer long ago. If interested in this patch for
enscript mailto:pefu@sourceforge.net

you may want to edit if desired to set color and font characteristics.
See the cvsgraph.conf documentation. No edits are required in
cvsgraph.conf for operation with ViewVC.
SUBVERSION INTEGRATION
----------------------
Unlike the CVS integration, which simply wraps the RCS and CVS utility
programs, the Subversion integration requires additional Python
libraries. To use ViewVC with Subversion, make sure you have both
Subversion itself and the Subversion Python bindings installed. These
can be obtained through typical package distribution mechanisms, or
may be build from source. (See the files 'INSTALL' and
'subversion/bindings/swig/INSTALL' in the Subversion source tree for
more details on how to build and install Subversion and its Python
bindings.)
Generally speaking, you'll know when your installation of Subversion's
bindings has been successful if you can import the 'svn.core' module
from within your Python interpreter. Here's an example of doing so
which doubles as a quick way to check what version of the Subversion
Python binding you have:
% python
Python 2.2.2 (#1, Oct 29 2002, 02:47:30)
[GCC 2.96 20000731 (Red Hat Linux 7.2 2.96-108.7.2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from svn.core import *
>>> "%s.%s.%s" % (SVN_VER_MAJOR, SVN_VER_MINOR, SVN_VER_PATCH)
'1.3.1'
>>>
Note that by default, Subversion installs its bindings in a location
that is not in Python's default module search path (for example, on
Linux systems the default is usually /usr/local/lib/svn-python). You
need to remedy this, either by adding this path to Python's module
search path, or by relocating the bindings to some place in that
search path.
For example, you might want to create .pth file in your Python
installation directory's site-packages area which tells Python where
to find additional modules (in this case, you Subversion Python
bindings). You would do this as follows (and as root):
$ echo "/path/to/svn/bindings" > /path/to/python/site-packages/svn.pth
(Though, obviously, with the correct paths specified.)
Configuration of the Subversion repositories happens in much the same
way as with CVS repositories, only with the 'svn_roots' configuration
variable instead of the 'cvs_roots' one.
cvsgraph.conf for operation with viewcvs.
IF YOU HAVE PROBLEMS ...
------------------------
If nothing seems to work:
If you've trouble to make viewcvs.cgi work:
* 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 webserver; locate the logfiles and try to find hints which
explain the malfunction
=== If nothing seems to work:
* View the entries in the webserver's error.log
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 webserver; locate the logfiles and try to find hints
which explain the malfunction
o view the entries in the webserver's error.log
If ViewVC seems to work but doesn't show the expected result (Typical
error: you can't see any files)
* Check whether the CGI-script has read-permissions to your
CVS-Repository. The CGI-script generally runs as the same user
that the web server does, often user 'nobody' or 'httpd'.
* Does ViewVC find your RCS utilities? (edit rcs_dir)
If something else happens or you can't get it to work:
* Check the ViewVC home page:
http://viewvc.org/
* Review the ViewVC mailing list archive to see if somebody else had
the same problem, and it was solved:
http://viewvc.tigris.org/servlets/SummarizeList?listName=users
* Check the ViewVC issue database to see if the problem you are
seeing is the result of a known bug:
http://viewvc.tigris.org/issues/query.cgi
o make sure there is a trailing slash on the URL. for example:
* Send mail to the ViewVC mailing list, users@viewvc.tigris.org.
NOTE: make sure you provide an accurate description of the problem
-- including the version of ViewVC you are using -- and any
relevant tracebacks or error logs.
http://www.example.com/cgi-bin/viewcvs.cgi/
(ViewCVS should perform a redirection to ensure this, but a report
has indicated that it doesn't always do this... please send more
of these bug reports if you run into this)
=== If viewcvs 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 does viewcvs find your RCS utilities? (edit rcs_path)
=== If something else happens or you can't get it to work:
o check the ViewCVS home page:
http://viewcvs.sourceforge.net/
o review the ViewCVS mailing list archive to see if somebody else had
the same problem, and it was solved:
http://mailman.lyra.org/pipermail/viewcvs/
o send mail to the ViewCVS mailing list: viewcvs@lyra.org
NOTE: make sure you provide an accurate description of the problem
and any relevant tracebacks or error logs.

# Very simple inetd/xinetd "cvsnt rcsfile" service

# from mod_python to die. This gives empty diff outputs or different errors like
# "Error: Rlog output ended early. Expected RCS file ..."
# This script removes forking from mod_python code and solves the issue.
# Additional profit of this script is that you can probably browse REMOTE cvs
# repositories, if you expose this service to ViewVC, although it is not tested.
# USAGE: (local) create an inetd service with this script as server listening

Granny.py - display CVS annotations in HTML
with lines colored by code age in days.
Original Perl version by J. Gabriel Foster (gabe@sgrail.com)
Posted to info-cvs on 02/27/1997
You can still get the original shell archive here:
http://www.geocrawler.com/archives/3/382/1997/2/0/2103824/
Perl modifications for NT by Marc Paquette (marcpa@cam.org)
Python port and CGI modifications by Brian Lenihan (brianl@real.com)
From the original granny.pl README:
--
What is Granny? Why do I care?
Granny is a tool for viewing cvs annotation information graphically. Using
Netscape, granny indicates the age of lines by color. Red lines are new,
blue lines are old. This information can be very useful in determining
what lines are 'hot'. New lines are more likely to contain bugs, and this
is an easy way to visualize that information.
Requirements:
Netscape (version 2.0 or better)
Perl5
CVS 1.9 (1.8 should work, but I have not tried it.)
Installation:
Put granny somewhere in your path. You may need to edit the
first line to point to your perl5 binary and libraries.
What to do:
Run granny just like you would 'cvs annotate' for a single file.
granny thefile.C
To find out who is to blame for that new 'feature'.
granny -U thefile.C
For all your options:
granny -h
Questions, Comments, Assertions?
send e-mail to the author: Gabe Foster (gabe@sgrail.com)
Notes:
I'm not the first person to try this sort of display, I just read about it
in a magazine somewhere and decided that cvs had all the information
I needed. To whomever first had this idea, it's a great one.
Granny is free, please use it as you see fit. I give no warranties.
As a courtesy, I ask that you tell me about any modifications you have made,
and also ask that you acknowledge my work if you use Granny in your own
software.
--
Granny.py:
granny.py [-h][-d days][-i input][-o output][-DUV] file
-h: Get this help display.
-i: Specify the input file. (Use - for stdin.)
-o: Specify the output file. (Use - for stdout.)
-d: Specify the day range for the coloring.\n
-r: Specify the cvs revision of the file.
-D: Display the date the line was last edited.
-U Display the user that last edited the line.
-V: Display the version the line was last edited.
By default, granny.py executes cvs annotate on a FILE and
runs netscape to display the graphic.
It is assumed that cvs and Netscape (for command line version) are
in your path.
If granny.py is placed in the cgi-bin directory of your Web
server, it will act as a CGI script. The working directory
defaults to /usr/tmp, but it can be overridden in the class
constructor:
A = CGIAnnotate(tempdir='/tmp')
Required fields:
root The full path to the cvs root directory.
Name The module/filename of the annotated file.
Optional fields:
rev The cvs revision number to use. (default HEAD).
Set the following fields to display extra info:
showUser Display the user that last edited the line.
showVersion Display version that the line was last edited in.
showDate Display the date the line was last edited.
http://yourserver.yourdomain.com/cgi-bin/granny.py?root=/cvsroot&Name=module/file
TODO:
Add support for determining the MIME type of files and/or a binary check.
- easily done by parsing Apache (mime.conf) or Roxen (extensions) MIME
files.
Consider adding buttons to HTML for optional display fields.
Add support for launching other browsers.

# FORMAT INFORMATION
#
# This file is delineated by sections, specified in [brackets]. Within each
# section, are a number of configuration settings. These settings take the
# form of: name = value. Values may be continued on the following line by
# indenting the continued line.
#
# WARNING: indentation *always* means continuation. name=value lines should
# always start in column zero.
#
# Comments should always start in column zero, and are identified with "#".
#
# Certain configuration settings may have multiple values. These should be
# separated by a comma. The settings where this is allowed are noted below.
#
# Any other setting that requires special syntax is noted at that setting.
#
#---------------------------------------------------------------------------
[general]
#
# This setting specifies each of the CVS roots on your system and assigns
# names to them. Each root should be given by a "name: path" value. Multiple
# roots should be separated by commas.
#
cvs_roots =
Development : /home/cvsroot
# this is the name of the default CVS root.
default_root = Development
# uncomment if the RCS binaries are not on the standard path
#rcs_path = /usr/bin/
#
# This is a pathname to a MIME types file to help viewcvs to guess the
# correct MIME type on checkout.
#
# If you are having problems with the default guess on the MIME type, then
# uncomment this option and point it at a MIME type file.
#
# For example, you can use the mime.types from apache here:
#mime_types_file = /usr/local/apache/conf/mime.types
# This address is shown in the footer of the generated pages.
# It must be replaced with the address of the local CVS maintainer.
address = <a href="mailto:cvs-admin@insert.your.domain.here">No CVS admin address has been configured</a>
# this title is used on the main entry page
main_title = CVS Repository
#
# This should contain a list of modules in the repository that should not be
# displayed (by default or by explicit path specification).
#
# This configuration can be a simple list of modules, or it can get quite
# complex:
#
# *) The "!" can be used before a module to explicitly state that it
# is NOT forbidden. Whenever this form is seen, then all modules will
# be forbidden unless one of the "!" modules match.
#
# *) Shell-style "glob" expressions may be used. "*" will match any
# sequence of zero or more characters, "?" will match any single
# character, "[seq]" will match any character in seq, and "[!seq]"
# will match any character not in seq.
#
# *) Tests are performed in sequence. The first match will terminate the
# testing. This allows for more complex allow/deny patterns.
#
# Tests are case-sensitive.
#
forbidden =
# Some examples:
#
# Disallow "example" but allow all others:
# forbidden = example
#
# Disallow "example1" and "example2" but allow all others:
# forbidden = example1, example2
#
# Allow *only* "example1" and "example2":
# forbidden = !example1, !example2
#
# Forbid modules starting with "x":
# forbidden = x*
#
# Allow modules starting with "x" but no others:
# forbidden = !x*
#
# Allow "xml", forbid other modules starting with "x", and allow the rest:
# forbidden = !xml, x*, !*
#
#
# This option provides a mechanism for custom key/value pairs to be
# available to templates. These are stored in key/value files (KV files).
#
# Pathnames to the KV files are listed here, specified as absolute paths
# or relative to this configuration file. The kV files follow the same
# format as this configuration file. It may have multiple, user-defined
# sections, and user-defined options in those sections. These are all
# placed into a structure available to the templates as:
#
# kv.SECTION.OPTION
#
# Note that an option name can be dotted. For example:
#
# [my_images]
# logos.small = /images/small-logo.png
# logos.big = /images/big-logo.png
#
# Templates can use these with a directive like: [kv.my_images.logos.small]
#
# Note that sections across multiple files will be merged. If two files
# have a [my_images] section, then the options will be merged together.
# If two files have the same option name in a section, then one will
# overwrite the other (it is unspecified regarding which "wins").
#
# To further categorize the KV files, and how the values are provided to
# the templates, a KV file name may be annotated with an additional level
# of dotted naming. For example:
#
# kv_files = [asf]kv/images.conf
#
# Assuming the same section as above, the template would refer to an image
# using [kv.asf.my_images.logos.small]
#
# Lastly, it is possible to use %lang% in the filenames to specify a
# substitution of the selected language-tag.
#
kv_files =
# example:
# kv_files = kv/file1.conf, kv/file2.conf, [i18n]kv/%lang%_data.conf
#
#
# The languages available to ViewCVS. There are several i18n mechanisms
# available:
#
# 1) using key/value extension system and reading KV files based on
# the selected language
# 2) GNU gettext to substitute text in the templates
# 3) using different templates, based on the selected language
#
# ### NOTE: at the moment, the GNU gettext style is not implemented
#
# This option is a comma-separated list of language-tag values. The first
# language-tag listed is the default language, and will be used if an
# Accept-Language header is not present in the request, or none of the
# user's requested languages are available. If there are ties on the
# selection of a language, then the first to appear in the list is chosen.
#
languages = en-us
# other examples:
#
# languages = en-us, de
# languages = en-us, en-gb, de
# languages = de, fr, en-us
#
#---------------------------------------------------------------------------
[templates]
#
# The templates are specified relative to the configuration file. Absolute
# paths may be used, if you want to keep these elsewhere.
#
# If %lang% occurs in the pathname, then the selected language will be
# substituted.
#
# Note: the selected language is defined by the "languages" item in the
# [general] section, and based on the request's Accept-Language
# header.

# taken to escape the constructed expression.
# - A '$' at the end of the merge_to expression can be important to

<h1>ViewVC 1.1.0 Release Notes</h1>
<div class="h2">
<h2 id="introduction">Introduction</h2>
<p>ViewVC 1.1.0 is the superset of all previous ViewVC releases.</p>
</div> <!-- h2 -->
<div class="h2">
<h2 id="compatibility">Compatibility</h2>
<p>Each ViewVC release strives to maintain URL stability with previous
releases, and 1.1.0 is no exception. All URLs considered valid for
previous ViewVC releases should continue to work correctly in this
release, though possibly only via the use of HTTP redirects
(generated by ViewVC itself).</p>
<p>The commits database functionality has changed in ViewVC 1.1.0 in
way that breaks compatibility with prior ViewVC releases, but only
for new database instantiations. ViewVC 1.1.0 will continue to
understand (for both read and write operations) the previous
schema, so you are not required to rebuild your commits database
for ViewVC 1.1.0 compatibility. By default, new commits databases
created using the 1.1.0 version of the <code>make-database</code>
script will use a new database schema that is unreadable by
previous ViewVC versions. However, if you need a database which
can co-exist with a previous ViewVC version, you can use
the <code>--version=1.0</code> option
to <code>make-database</code>.</p>
<p>The ViewVC configuration files and template language have changed
dramatically. See the file <code>docs/upgrading-howto.html</code>
in the release for information on porting existing versions of
those items for use with ViewVC 1.1.0.</p>
</div> <!-- h2 -->
<div class="h2">
<h2 id="compatibility">Features and Fixes</h2>
<div class="h3">
<h3 id="">Extensible path-based authorization w/ Subversion authz support</h3>
<p>In a nutshell, ViewVC is now able to do path-based authorization.
ViewVC 1.0 has a configuration option for naming 'forbidden'
modules, but it is really limited &mdash; it basically just makes a
universal decision about which top-level directories in every
hosted repository should be hidden by ViewVC. People want
more, and specifically requested that ViewVC learn how to honor
Subversion's authz files and semantics. So, along with some other
types of authorization approaches, that's what ViewVC 1.1 can now
do. If you are using mod_authz_svn with Apache today, or
svnserve's built-in authorization support, then you can now point
ViewVC to the same authz configuration file and have it honor the
access rules you've defined for your repositories.</p>
<p>Note that ViewVC does <strong>not</strong> handle authentication,
though. You'll need to configure your web server to demand login
credentials from users, which the web server itself can then hand
off to ViewVC for application against the authorization rules
you've defined.</p>
<p class="warning">WARNING: The root listing view does not consult the
authorization subsystem when deciding what roots to display to a
given user. If you need to protect your root names, consider
disabling it by removing <code>roots</code> from the set of views
listed in the <code>allowed_views</code> configuration option.
<strong>UPDATE: This was fixed in ViewVC 1.1.3.</strong></p>
<p class="warning">WARNING: Support for path-based authorization is
incomplete in the experimental version control backend modules,
including the one that permits display of remote Subversion
repositories. <strong>UPDATE: This was fixed in ViewVC
1.1.15.</strong></p>
</div> <!-- h3 -->
<div class="h3">
<h3 id="">Subversion versioned properties display</h3>
<p>ViewVC 1.1 displays the properties that Subversion lets you store
on files and directories
(<code>svn:mime-type</code>, <code>svn:mergeinfo</code>,
<code>svn:ignore</code>, etc.). Directory properties are shown by
default at the bottom of that directory's entry listing. File
properties are displayed at the bottom of that file's
markup/annotate view.</p>
</div> <!-- h3 -->
<div class="h3">
<h3 id="">Unified markup and annotation views</h3>
<p>The "markup" and "annotate" views in ViewVC now have a unified look
and feel (driven by a single EZT template). Both views support
syntax highlighting and Subversion file property display.</p>
</div> <!-- h3 -->
<div class="h3">
<h3 id="">Unified, hassle-free Pygments-based syntax highlighting</h3>
<p>ViewVC 1.0 does syntax highlighting by working with GNU enscript, or
highlight, or php, or py2html &mdash; all these external tools just
to accomplish a single task. But they all do things in slightly
different ways. And if you configure them wrongly, you get strange
errors. <a href="http://www.pygments.org/">Pygments</a> (which is
also used by <a href="http://trac.edgewall.org/">Trac</a> for
syntax highlighting) is a Python package that requires no
configuration, is easier to use inside ViewVC, and so on. So
ViewVC 1.1 drops support for all those various old integrations,
and just uses Pygments for everything now. This change was about
developer and administrator sanity. There will be complaints, to
be sure, about how various color schemes differ and what file types
now are and aren't understood by the syntax highlighting engine,
but this change should vastly simplify the discussions of such
things.</p>
</div> <!-- h3 -->
<div class="h3">
<h3 id="">Better MIME detection and handling</h3>
<p>ViewVC typically consults a MIME types file to determine what kind
of file a given document is, based on its filename extension
(<code>.jpg</code> = <code>image/jpeg</code>, &hellip;). But
Subversion lets you dictate a file's MIME type using
the <code>svn:mime-type</code> property. ViewVC now recognizes and
honors that property as the preferred source of a file's MIME type.
This can be disabled in the configuration, though, which might be
desirable if many of your Subversion-versioned files carry the
generic <code>application/octet-stream</code> MIME type that
Subversion uses by default for non-human-readable files.</p>
<p>Also, ViewVC now allows you to specify multiple MIME type mapping
files that you'd like it to consult when determine the MIME type of
files based on their extensions. This allows administrators to
easily define their own custom mappings for ViewVC's benefit
without potentially affecting the mappings used by other site
services.</p>
</div> <!-- h3 -->
<div class="h3">
<h3 id="">Support for full content diffs</h3>
<p>ViewVC 1.1 expands the previously existing options of "colored
diff" and "long colored diff" with a new "full colored diff", which
shows the full contents of the changed file (instead of only the 3
or 15 lines of context shown via the older diff display types).</p>
</div> <!-- h3 -->
<div class="h3">
<h3 id="">Support for per-root configuration overrides</h3>
<p>In ViewVC 1.1, you can setup configuration option overrides on a
per-root (per-repository) basis (if you need/care to do so). See
the comments in the <code>viewvc.conf.dist</code> file for more on
how to do this.</p>
</div> <!-- h3 -->
<div class="h3">
<h3 id="">Optional email address obfuscation/mangling</h3>
<p>ViewVC can, when displaying revision metadata, munge strings that
look like email addresses to protect them from screen-scraping
spammers. For example, a log message that says, "Patch by:
cmpilato@red-bean.com" can optionally be displayed by ViewVC using
HTML entity encoding for the characters (a trick that causes no
visible change to the output, but that might confuse
unsophisticated spam bot crawlers) or as "Patch by: cmpilato@..."
(which isn't a complete email address at all, but might be enough
information for the human reading the log message to know who to
blame for the patch).</p>
</div> <!-- h3 -->
<div class="h3">
<h3 id="">Pagination improvements</h3>
<p>The way that ViewVC splits directory and log views across pages has
been reworked. The old way was "Fetch all the information you can
find, then display only one page's worth." The new way is "Fetch
only what you need to display the page requested, plus a little bit
of border information." This provides a large performance
enhancement for the default sort orderings.</p>

# CONFIGURATION
# -------------
#
# There are three forms of configuration:
#
# 1. edit the viewvc.conf created by the viewvc-install(er)
# 2. as (1), but delete all unchanged entries from viewvc.conf
# 3. do not use viewvc.conf and just edit the defaults in this file
# 1) edit the viewcvs.conf created by the viewcvs-install(er)
# 2) as (1), but delete all unchanged entries from viewcvs.conf
# 3) do not use viewcvs.conf and just edit the defaults in this file
#
# Most users will want to use (1), but there are slight speed advantages
# to the other two options. Note that viewvc.conf values are a bit easier
# to the other two options. Note that viewcvs.conf values are a bit easier
# to work with since it is raw text, rather than python literal values.
#
#
# A WORD ABOUT OPTION LAYERING/OVERRIDES
# --------------------------------------
#
# ViewVC has three "layers" of configuration options:
#
# 1. base configuration options - very basic configuration bits
# found in sections like 'general', 'options', etc.
# 2. vhost overrides - these options overlay/override the base
# configuration on a per-vhost basis.
# 3. root overrides - these options overlay/override the base
# configuration and vhost overrides on a per-root basis.
#
# Here's a diagram of the valid overlays/overrides:
#
# PER-ROOT PER-VHOST BASE
#
# ,-----------. ,-----------.

# | general | --> | general |

or attributes of objects contained in the data dictionary given to the
.generate() method.
Qualified names
---------------
Qualified names have two basic forms: a variable reference, or a string
constant. References are a name from the data dictionary with optional
dotted attributes (where each intermediary is an object with attributes,
of course).
Examples:
[varname]
[ob.attr]
["string"]
Simple directives
-----------------
[QUAL_NAME]
This directive is simply replaced by the value of the qualified name.
If the value is a number it's converted to a string before being
outputted. If it is None, nothing is outputted. If it is a python file
object (i.e. any object with a "read" method), it's contents are
outputted. If it is a callback function (any callable python object
is assumed to be a callback function), it is invoked and passed an EZT
Context object as an argument.
[QUAL_NAME QUAL_NAME ...]
If the first value is a callback function, it is invoked with an EZT
Context object as a first argument, and the rest of the values as
additional arguments.
Otherwise, the first value defines a substitution format, specifying
constant text and indices of the additional arguments. The arguments
are substituted and the result is inserted into the output stream.
Example:
["abc %0 def %1 ghi %0" foo bar.baz]
Note that the first value can be any type of qualified name -- a string
constant or a variable reference. Use %% to substitute a percent sign.
Argument indices are 0-based.
This directive is simply replaced by the value of identifier from the data
dictionary. QUAL_NAME might be a dotted qualified name refering to some
instance attribute of objects contained in the dats dictionary.
Numbers are converted to string though.
[include "filename"] or [include QUAL_NAME]
This directive is replaced by content of the named include file. Note
that a string constant is more efficient -- the target file is compiled
inline. In the variable form, the target file is compiled and executed
at runtime.
This directive is replaced by content of the named include file.

These five directives work similar to [if-any], but are only useful
within a [for ...]-block (see above). The odd/even directives are
for example useful to choose different background colors for
adjacent rows in a table. Similar the first/last directives might
be used to remove certain parts (for example "Diff to previous"
doesn't make sense, if there is no previous).

[is QUAL_NAME STRING] ... [else] ... [end]
[is QUAL_NAME QUAL_NAME] ... [else] ... [end]
The [is ...] directive is similar to the other conditional
directives above. But it allows to compare two value references or
a value reference with some constant string.
[define VARIABLE] ... [end]
The [define ...] directive allows you to create and modify template
variables from within the template itself. Essentially, any data
between inside the [define ...] and its matching [end] will be
expanded using the other template parsing and output generation
rules, and then stored as a string value assigned to the variable
VARIABLE. The new (or changed) variable is then available for use
with other mechanisms such as [is ...] or [if-any ...], as long as
they appear later in the template.
[format STRING] ... [end]
The format directive controls how the values substituted into
templates are escaped before they are put into the output stream. It
has no effect on the literal text of the templates, only the output
from [QUAL_NAME ...] directives. STRING can be one of "raw" "html"
"xml" or "uri". The "raw" mode leaves the output unaltered; the "html"
and "xml" modes escape special characters using entity escapes (like
&quot; and &gt;); the "uri" mode escapes characters using hexadecimal
escape sequences (like %20 and %7e).
[format CALLBACK]
The [is ...] directive is similar to the other conditional directives
above. But it allows to compare two value references or a value reference
with some constant string.
Python applications using EZT can provide custom formatters as callback
variables. "[format CALLBACK][QUAL_NAME][end]" is in most cases
equivalent to "[CALLBACK QUAL_NAME]"

work in CGI mode. It looks for a field 'script=URL' and tries to
use that URL as input file. If it can't find this field, the path
info (the part of the URL following the CGI script name) is
tried. In case no host is given, the host where the CGI script
lives and HTTP are used.

TIMESTAMP is the date and time that the revision was created, as an

PYTEXT.
The returned value is a list of tuples, formatted like this:
[('keyword', 0, 6, None),
('keyword', 11, 17, None),

TAG is one of 'keyword', 'string', 'comment' or 'identifier'
SUBLIST is not used, hence always None.
