<h1>Upgrading ViewVC</h1>

<div class="h2">
<h2 id="introduction">Introduction</h2>

<p>This document describes some of the things that you will need to 
   consider, change, or handle when upgrading an existing ViewVC
   or ViewCVS installation to a newer version.</p>

<p>Upgrading from an ancient version to the latest version
   isn't necessarily a multi step process.  The instructions are only
   organized that way.  You can certainly upgrade in a single step.</p>

<p>It is always recommended to install the new version in a fresh
   directory and to carefully compare the configuration files.  A
   possible approach is to name the directories
   <code>/usr/local/viewvc-1.0</code>,
   <code>/usr/local/viewvc-1.1</code> and so on and than create a
   symbolic link <code>viewvc</code> pointing to the production
   version.  This way you can easily test several versions and switch
   back if your users start to complain.</p>

<div class="h2">
<h2 id="sec-from-1-0">Upgrading From ViewVC 1.0</h2>

<p>This section discusses how to upgrade ViewVC 1.0.x to ViewVC 1.1.x.</p>

<div class="h3">
<h3>root_as_url_component Now Enabled by Default</h3>
    
<p>In ViewVC 1.1, the <code>root_as_url_component</code> configuration
   option is now enabled by default.  This option causes ViewVC URLs
   to be of the form
   <code>&hellip;/root-name/path-in-root[?&hellip;]</code> instead of
   <code>&hellip;/path-in-root/?root=root-name[&amp;&hellip;]</code>,
   and makes for a much more intuitive user experience,
   navigation-wise, when ViewVC is serving up multiple version control
   repositories.  When in this mode, ViewVC will automatically perform
   the obvious redirection for URLs which have a <code>root=</code>
   CGI parameter.</p>

<p>Unfortunately, there's a catch.  Older URLs for the default root
   (specified by the <code>default_root</code> configuration option)
   were optimized to <em>not</em> include the <code>root=</code> CGI
   parameter.  This means they look unfortunately similar to the newer
   root-in-the-path URL format, and ViewVC will not attempt to
   redirect them.  But ViewVC won't be able to handle them, either.
   So, old-style default-root URLs, when aimed at a ViewVC for which
   the <code>root_as_url_component</code> option has been subsequently
   enabled, will result in an error.  If you need to preserve the
   functionality of those old URLs, you'll need to either disable
   <code>root_as_url_component</code>, or use some other mechanism
   (like server URL rewriting) to morph them into compliance with the
   new URL format.</p>

</div>

<div class="h3">
<h3>Path-Based Authorization / Forbidden Modules</h3>
    
<p>ViewVC 1.1 introduces a new pluggable authorization (authz)
   subsystem which gives administrators greater control over the
   accessibility of the information ViewVC displays in its output.
   ViewVC provides a number of working authz modules and a framework for
   configuring them.  But of specific interest to folks upgrading from
   ViewVC 1.0 is that one of these new modules has replaced the
   handling of forbidden modules.  As such, the <code>forbidden</code>
   configuration option now lives under the configuration section
   specific to that authz module.</p>

<p>Migrating your existing configuration of forbidden modules should
   be fairly straightforward:</p>

<ol>

   <li>In the new "authz-forbidden" section of viewvc.conf, set the
       <code>forbidden</code> option to the same value as the
       <code>forbidden</code> option in your ViewVC 1.0.x
       configuration's "general" section.</li>

   <li>In the new "authz-forbiddenre" section of viewvc.conf, set the
       <code>forbiddenre</code> option to the same value as the
       <code>forbiddenre</code> option in your ViewVC 1.0.x
       configuration's "general" section.</li>

   <li>Finally, ensure that that the new <code>authorizer</code>
       option is set to either "forbidden" or "forbiddenre", depending
       on which of those you were using in ViewVC 1.0.x.</li>

</ol>

<p>Of course, you might wish to take advantage of another of the
   provided authz modules.  Or, you might wish to write a brand new
   one for your purposes.  The flexibility is yours.</p>

<p><strong>Known Issues:</strong></p>

<ul>

   <li>ViewVC does not provide an <em>authentication</em> framework.
       It does, however, inherit authenticated usernames as determined
       by the HTTP server (Apache, e.g.) via the CGI environment.  So,
       any authorization module that assigns privileges based on
       usernames will work only if ViewVC is deployed in a way that
       requires successful authentication (as opposed to allowing
       anonymous access).</li>

   <li>Currently, the root listing view only honors the global or
       vhost-specific configurations, <em>not</em> any root-specific
       configuration.  In the event that ViewVC is using root-specific
       configuration for its authorization stuffs, this may cause
       either the unintended leak of root names to users or the
       inability to see roots at all.  However, for root-specific
       ViewVC views, all configuration &mdash; include root-specific
       configuration &mdash; is honored.  If you are concerned about
       leaking root names in the root listing view, you might consider
       disabling that view altogether by removing <code>roots</code>
       from the list of views specified in the 
       <code>allowed_views</code> configuration option.</li>

   <li>The experimental module which allows ViewVC to serve up views
       of remote Subversion repositories is not yet fully integrated
       with the authorization subsystem, and almost certainly will
       leak privileged data.  Sorry.  That's (one reason) why it's
       experimental.</li>

</ul>

</div>

<div class="h3">
<h3>Syntax Highlighting</h3>

<p>ViewVC 1.0.x supports syntax highlighting provided by multiple
   third-party highlighting engines, including GNU enscript, GNU
   source-highlight, highlight, php, and py2html.  Unfortunately, each
   of those integrations worked differently than the others.  Some
   supported line numbers, some didn't; some were under active
   development and recognized newer languages; some weren't; each had
   its own set of CSS stylations that needed to be customized;
   etc.</p>

<p>In ViewVC 1.1, we've dropped support for all of those integations
   in favor of a single integration with <a
   href="http://www.pygments.org/" >Pygments</a>, a
   Python-module-based syntax highlighting engine.  As such, the
   configuration options for the various other engines (both those
   that enabled the integration and those that specified the locations
   of the third-party tools) have been removed from ViewVC, and have
   been replaced by a single new configuration option:
   <code>enable_syntax_coloration</code>.</p>

<p>The list of removed options is as follows:</p>

<ul>
  <li>options/enscript_path</li>
  <li>options/highlight_convert_tabs</li>
  <li>options/highlight_path</li>
  <li>options/markup_line_numbers</li>
  <li>options/php_exe</li>
  <li>options/py2html_path</li>
  <li>options/use_enscript</li>
  <li>options/use_highlight</li>
  <li>options/use_pagesize</li>
  <li>options/use_php</li>
  <li>options/use_py2html</li>
</ul>

</div>

<div class="h3">
<h3>Checkin Database</h3>

<p>ViewVC 1.1 introduces to the <code>cvsdbadmin</code>
   and <code>svndbadmin</code> tools a new "purge" operation, which
   allows you to remove all the information related to a given root
   from your checkins database (without disturbing the information
   associated with other roots).  Likewise, the "rebuild" command in
   those tools now implies a "purge" followed by an update.</p>

<p>As a related change, the <code>svndbadmin</code> program's
   "rebuild" subcommand has had its purpose become more defined.  It
   no longer accepts a revision argument, and therefore can now only
   be used to completely rebuild the entirety of the checkin database
   information for a Subversion repository (instead of being able to
   only update the information related to single Subversion revision).
   For per-revision updating, use <code>svndbadmin update</code> and
   provide a revision (or revision range).  And to get the previous
   rebuild-a-revision effect, pass the new <code>--force</code> option
   to <code>svndbadmin update</code>.</p>

<p>In other words, where you once did this:</p>

<blockquote><pre>$ svndbadmin rebuild /path/to/repository 1234
</pre>
</blockquote>

<p>you now need to do this:</p>

<blockquote><pre>$ svndbadmin update /path/to/repository 1234 --force
</pre>
</blockquote>

<p>To enhance the performance of the new "purge" operation, ViewVC 1.1
   introduces some slight changes to the checkin database schema.  If
   you use the <code>make-database</code> tool to (re)create your
   checkins database, it will by default employ the new database
   schema.  This should cause the database to be virtually unusable by
   previous versions of ViewVC, and that's by design.  If, however,
   you need to (re)create your checkins database and you require
   compatibility with previous versions of ViewVC or ViewCVS, simply
   pass the "--version=1.0" option to the <code>make-database</code>
   script.  Note that your "purge" and "rebuild" operations could be
   abysmally slow, though, as that version of the database schema is
   not optimized for those operations.</p>

</div>

<div class="h3">
<h3>Configuration Options</h3>

<p>This section covers changes to configuration options not already
   discussed in other sections pertaining to this upgrade.</p>

<p>In ViewVC 1.1, a new "utilities" section was added to the
   viewvc.conf file.  All the options used for configuring the
   locations of various helper applications that ViewVC uses which
   were previously scattered throughout the configuration file are now
   all centralized in this one new section.  To accomplish this, the
   following options were added:</p>

<ul>
  <li>utilities/cvsgraph</li>
  <li>utilities/cvsnt</li>
  <li>utilities/diff</li>
  <li>utilities/rcs_dir</li>
  <li>utilities/svn</li>
</ul>

<p>&hellip;and these were removed:</p>

<ul>
  <li>general/cvsnt_ext_path</li>
  <li>general/rcs_path</li>
  <li>general/svn_path</li>
  <li>options/cvsgraph_path</li>
</ul>

<p>All the options which governed which ViewVC views were enabled have
   been consolidated into a single new option.  This new option:</p>

<ul>
  <li>options/allowed_views</li>
</ul>

<p>&hellip;replaces these, which have been removed:</p>

<ul>
  <li>options/allow_annotate</li>
  <li>options/allow_markup</li>
  <li>options/allow_tar</li>
</ul>

<p>ViewVC now honors the "svn:mime-type" property stored on
   Subversion-versioned files as the primary source of MIME type
   determination (before falling back to name-based MIME mappings and
   such).  However, this can negatively affect the viewability of
   certain files &mdash; especially images &mdash; whose
   "svn:mime-type" properties are set incorrectly, such as will happen
   if Subversion itself merely determines that the file isn't
   human-readable and uses the "application/octet-stream" MIME type to
   record this determination.  To make ViewVC <em>not</em> honor the
   "svn:mime-type" property value, set the <code>svn_ignore_mimetype</code>
   configuration option.</p>

<p>Speaking of MIME types, the option <code>mime_types_file</code> is
   now <code>mime_types_files</code>, as it now carries multiple paths
   to MIME mappings files, ordered by preference.</p>

<p>The <code>use_rcsparse</code> option was moved from the "general"
   section to the "options" section.</p>

<p>The <code>log_sort</code> option's value "cvs" has been renamed to
   "none" (for general application across all supported version
   control systems).</p>

<p>Custom sections which define per-virtual-host configuration option
   overrides must now have their names prefixed with "vhost-".  Also,
   instead of a hyphen (-) between the virtual host name and the base
   configuration section being overridden, now there should be a
   forward slash character (/).  For example, the following
   configuration which was valid in ViewVC 1.0 is no longer valid:</p>

<blockquote><pre>[vhosts]
all = viewvc.*

[all-options]
allowed_views = annotate, diff, markup, tar
</pre>
</blockquote>

<p>This now needs to be written like so:</p>

<blockquote><pre>[vhosts]
all = viewvc.*

[vhost-all/options]
allowed_views = annotate, diff, markup, tar
</pre>
</blockquote>

<p>The following is a grab-bag of additional new options:</p>

<ul>
  <li>options/hide_errorful_entries</li>
  <li>options/mangle_email_addresses</li>
</ul>

</div>

<div class="h3">
<h3>Templates</h3>
    
<p>This section describes template variable changes introduced in this
   release.  See the <a href="./template-authoring-guide.html">Template
   Authoring Guide</a> for the current set of variables available to
   each templates.</p>

<p>One notable change in ViewVC 1.1 is that the markup.ezt and
   annotate.ezt templates have been combined into a single file.ezt
   template.</p>

<p>Also, the configuration options under the <code>[templates]</code>
   section are now paths relative to the configured template directory
   (either the value of the <code>options/template_dir</code>
   option, or the default "templates" directory), instead of being
   relative to the configuration location.</p>

<h2 id="sec-from-0-9">Upgrading From ViewCVS 0.9</h2>

<p>This section discusses how to upgrade ViewCVS 0.9 to ViewVC 1.0.</p>

<div class="h3">
<h3>CGI Stubs</h3>
    
<p>The CGI stub scripts haved been moved from
   <code>&lt;VIEWVC_INSTALLATION_DIRECTORY&gt;/cgi/</code> to
   <code>&lt;VIEWVC_INSTALLATION_DIRECTORY&gt;/bin/cgi/</code>, so
   you will need update any ScriptAlias directives pointing to them in
   your apache configuration. Also, the contents of these scripts have
   changed, so you may need to replace copies of the old scripts you
   put in other directories.</p>

</div>

<div class="h3">
<h3>Checkin Database</h3>
    
<p>ViewVC 1.0 reads and writes commit times in the MySQL database in
   UTC time rather than local time.  This can cause times displayed on
   the query page to be a few hours off if an old database is being
   used with a new version of ViewVC.  The best way to fix this is to
   rebuild the database with the new version of cvsdbadmin, but it
   is also possible to enable a backwards compatibility mode by
   setting <code>utc_time = 0</code> at the top of lib/dbi.py</p>

</div>

<div class="h3">
<h3>"checkout_magic" Option</h3>

<p>In ViewVC 1.0, the <code>checkout_magic</code> option has been
   disabled by default to provide a simpler URL scheme that works
   safely with URL authorization. Most users will not notice any
   difference in behavior, but users who had been using ViewCVS to
   browse the contents of static HTML pages stored in a repository
   may notice that links and images in those pages targetted at other
   files in the repository no longer display correctly. The new
   <code>default_file_view</code> option can be used to solve this
   problem and, if neccessary, <code>checkout_magic</code> can also
   be re-enabled. The <code>viewcvs.conf</code> file describes these
   options in detail.</p>

<h3>Templates</h3>
    
<p>The templates have changed drastically in this version of ViewVC.
   If you are using customized templates from 0.9 or earlier, you will want
   to port your old customizations to the new template files instead of
   trying to get the old template files to work with the new ViewVC.</p>

<p>There is a new <a href="template-authoring-guide.html">Template
   Authoring Guide</a> for ViewVC 1.0 templates that can help you
   with your customizations. And the chart below lists all 0.9 
   template variables and shows what's become of them in 1.0.</p>

<h3>Template Arrangement</h3>
    
<p>The default templates have been rearranged a bit in ViewVC 1.0.
   Specifically, "header.ezt" and "footer.ezt" have moved into the
   "templates/include/" subdirectory.  Also, "directory.ezt" and
   "dir_alternate.ezt" now reference new template files
   "dir_header.ezt" and "dir_footer.ezt", also found in the
   "templates/include/" subdirectory.</p>

<p>Notably, the "markup.ezt" and "annotate.ezt" templates are now
   fully self-contained.  That is, the markup and annotation data
   generated by ViewVC is now accessible in those templates just like
   other template variables.  As a result, ViewVC now has no more
   internal need for the <var>templates.footer</var> configuration
   variable, so that variable has been removed from the default
   configuration file.</p>

<div class="h2">
<h2 id="sec-from-0-8">Upgrading From ViewCVS 0.8</h2>

<p>This section discusses how to upgrade ViewCVS 0.8 to version
   0.9 or a later version of the software.</p>
    
<p><strong>NOTE:</strong> these changes will bring you up to the
   requirements of version 0.9. You must also follow the directions
   for <a href="#sec-from-0-9">upgrading from 0.9</a>.</p>

<div class="h3">
<h3>Configuration Options</h3>

<p>More templates were introduced in version 0.8 of the software,
   which made many of the configuration options obsolete. This section
   covers which options were removed. If you made any changes to these
   options, then you will need to make corresponding changes in the
   templates.</p>

      <dl>
	<dt>
	  Colors:
	  <strong>diff_heading</strong>,
	  <strong>diff_empty</strong>,
	  <strong>diff_remove</strong>,
	  <strong>diff_change</strong>,
	  <strong>diff_add</strong>,
	  and <strong>diff_dark_change</strong>
	</dt>
	<dd>
	  These options have been incorporated into the
	  <code>diff.ezt</code> template.

	  <p></p>
	</dd>

	<dt><strong>markup_log</strong></dt>
	<dd>
	  This option has been incorporated into the
	  <code>markup.ezt</code> template.

	  <p></p>
	</dd>

        <dt>Colors: <strong>nav_header</strong>
          and <strong>alt_background</strong></dt>
	<dd>
	  These options have been incorporated into the
	  <code>header.ezt</code> template.

	  <p></p>
	</dd>

        <dt>
	  Images:
          <strong>back_icon</strong>,
          <strong>dir_icon</strong>,
          and <strong>file_icon</strong>
        </dt>
	<dd>
	  These options have been incorporated into the
	  <code>directory.ezt</code>, <code>header.ezt</code>,
	  <code>log.ezt</code>, <code>log_table.ezt</code>, and
	  <code>query.ezt</code> templates.

	  <p></p>
	</dd>

	<dt><strong>use_java_script</strong>
          and <strong>open_extern_window</strong></dt>
	<dd>
	  The templates now use JavaScript in all applicable places,
	  and open external windows for most downloading and viewing
	  of files. If you wish to not use JavaScript and/or external
	  windows, then remove the feature(s) from the templates.

	  <p></p>
	</dd>

	<dt><strong>show_author</strong></dt>
	<dd>
          Changing this option would be quite strange and rare. If you
          do not want to show the author for the revisions, then you
          should remove it from the various templates.

	  <p></p>
	</dd>

	<dt><strong>hide_non_readable</strong></dt>
	<dd>
          This option was never used, so it has been removed.

	  <p></p>
	</dd>

	<dt><strong>flip_links_in_dirview</strong></dt>
	<dd>
          This option is no longer available. If you want the links in
          your directory view flipped, then you may use the
          <code>dir_alternate.ezt</code> template.

	  <p></p>
	</dd>

      </dl>

<div class="h3">
<h3>Template Variables</h3>

<p>Some template variables that were available in 0.8 have been
   removed in 0.9. If you have custom templates that refer to these
   variables, then you will need to modify your templates.</p>

	    <dl>
	      <dt><code>directory.ezt</code>: <var>headers</var></dt>
	      <dd>
		The headers are now listed explicitly in the template,
		rather than made available through a list.
		<p></p>
	      </dd>

	      <dt>
		<code>directory.ezt</code>:
		<var>rows.cols</var>,
		and <var>rows.span</var>
	      </dt>
	      <dd>
		These variables were used in conjunction with the
		<var>headers</var> variable to control the column
		displays. This is now controlled explicitly within the
		templates.
		<p></p>
	      </dd>

	      <dt><code>directory.ezt</code>:
		<var>rev_in_front</var></dt>
	      <dd>
		This was used to indicate that revision links should
		be used in the first column, rather than in their
		standard place in the second column. Changing the
		links should now be done in the template, rather than
		according to this variable. You may want to look at
		the <code>dir_alternate.ezt</code> template, which has
		the revision in front.
		<p></p>
	      </dd>

	      <dt><code>directory.ezt</code>:
		<var>rows.attic</var>
		and <var>rows.hide_attic_href</var></dt>
	      <dd>
		These variable were used to manage the hide and
		showing of the contents of the <code>Attic/</code>
		subdirectory. Several new variables were introduced
		which can be used to replace this functionality:
		<var>show_attic_href</var>,
		<var>hide_attic_href</var>, and <var>rows.state</var>.
		<p></p>
