>LDAP authentication is a module for Bugzilla's plugin
authentication architecture.
</P
><P
>&#13; The existing authentication
scheme for Bugzilla uses email addresses as the primary user ID, and a
password to authenticate that user. All places within Bugzilla where
you need to deal with user ID (e.g assigning a bug) use the email
address. The LDAP authentication builds on top of this scheme, rather
than replacing it. The initial log in is done with a username and
password for the LDAP directory. This then fetches the email address
from LDAP and authenticates seamlessly in the standard Bugzilla
authentication scheme using this email address. If an account for this
address already exists in your Bugzilla system, it will log in to that
account. If no account for that email address exists, one is created at
the time of login. (In this case, Bugzilla will attempt to use the
"displayName" or "cn" attribute to determine the user's full name.)
After authentication, all other user-related tasks are still handled by
email address, not LDAP username. You still assign bugs by email
address, query on users by email address, etc.

You will most probably like something like this:
o conf makepl_arg "LIB=~/myperl/lib \
INSTALLMAN1DIR=~/myperl/man/man1 \
INSTALLMAN3DIR=~/myperl/man/man3"
install Sybase::Sybperl
You can make this setting permanent like all "o conf" settings with "o conf commit".
You will have to add ~/myperl/man to the MANPATH environment variable and also tell your Perl programs to
look into ~/myperl/lib, e.g. by including
use lib "$ENV{HOME}/myperl/lib";
or setting the PERL5LIB environment variable.
Another thing you should bear in mind is that the UNINST parameter should never be set if you are not root.</PRE

Perl directory. Set the MANPATH variable and PERL5LIB variable, so
that the installation of the modules goes smoother. (Setting

>shadowdb</DT
><DD
><P
>&#13; You run into an interesting problem when Bugzilla reaches a
high level of continuous activity. MySQL supports only table-level
write locking. What this means is that if someone needs to make a
change to a bug, they will lock the entire table until the operation
is complete. Locking for write also blocks reads until the write is
complete. Note that more recent versions of mysql support row level
locking using different table types. These types are slower than the
standard type, and Bugzilla does not yet take advantage of features
such as transactions which would justify this speed decrease. The
Bugzilla team are, however, happy to hear about any experiences with
row level locking and Bugzilla.
</P
><P
>&#13; The <SPAN
CLASS="QUOTE"
>"shadowdb"</SPAN
> parameter was designed to get around
this limitation. While only a single user is allowed to write to
a table at a time, reads can continue unimpeded on a read-only
shadow copy of the database. Although your database size will
double, a shadow database can cause an enormous performance
improvement when implemented on extremely high-traffic Bugzilla
databases.
</P
><P
>&#13; As a guide, on reasonably old hardware, mozilla.org began needing
<SPAN
CLASS="QUOTE"
>"shadowdb"</SPAN
> when they reached around 40,000 Bugzilla
users with several hundred Bugzilla bug changes and comments per day.
</P
><P
>&#13; The value of the parameter defines the name of the shadow bug
database. You will need to set the host and port settings from
the params page, and set up replication in your database server
so that updates reach this readonly mirror. Consult your database
documentation for more detail.

expression in version 2.16 or earlier, the user must be explicitly
removed from the group. This can easily be done by pressing
buttons named 'Remove Memberships' or 'Remove Memberships
included in regular expression' under the table.</P

>&#13; Upgrading Bugzilla is something we all want to do from time to time,
be it to get new features or pick up the latest security fix. How easy
it is to update depends on a few factors:

><A
NAME="upgrading-version-defns"
>3.11.1. Version Definitions</A
></H3
><P
>&#13; Bugzilla displays the version you are using at the top of most
pages you load. It will look something like '2.16.7' or '2.18rc3'
or '2.19.1+'. The first number in this series is the Major Version.
This does not change very often (that is to say, almost never);
Bugzilla was 1.x.x when it was first created, and went to 2.x.x
when it was re-written in perl in Sept 1998. If/When the major version
is changed to 3.x.x, it will signify a significant structural change
and will be accompanied by much fanfare and many instructions on
how to upgrade, including a revision to this page. :)
</P
><P
>&#13; The second number in the version is called the 'minor number', and
a release that changes the minor number is called a 'point release'.
An even number in this position (2.14, 2.16, 2.18, 2.20, etc.)
represents a stable version, while an odd number (2.17, 2.19, etc.)
represents a development version. In the past, stable point releases
were feature-based, coming when certain enhancements had been
completed, or the Bugzilla development team felt that enough
progress had been made overall. As of version 2.18, however,
Bugzilla has moved to a time-based release schedule; current plans
are to create a stable point release every 6 months or so after
2.18 is deployed.
</P
><P
>&#13; The third number in the Bugzilla version represents a bugfix version.
Bugfix Revisions are normally released only to address security
vulnerabilities; in the future, it is likely that the Bugzilla
development team will back-port bugfixes in a new point release to
the old point release for a limited period. Once enough of these
bugfixes have accumulated (or a new security vulnerability is
identified and closed), a bugfix release will be made. As an
example, 2.16.6 was a bugfix release, and improved on 2.16.5.

right for you depends on how long it has been since you last
installed, the degree to which you have customized your installation,
and/or your network configuration. (Some discussion of the various
methods of updating compared with degree and methods of local
customization can be found in <A

>Section 5.1.2</A

</P
><P
>&#13; The larger the jump you are trying to make, the more difficult it
is going to be to upgrade if you have made local customizations.
Upgrading from 2.18 to 2.18.1 should be fairly painless even if
you are heavily customized, but going from 2.14 to 2.18 is going
to mean a fair bit of work re-writing your local changes to use
the new files, logic, templates, etc. If you have done no local
changes at all, however, then upgrading should be approximately
the same amount of work regardless of how long it has been since
your version was released.

you must make is how you want to go about doing so. There are two
choices, and which you use depends mainly on the scope of your
modifications, and the method you plan to use to upgrade Bugzilla.
</P
><P
>&#13; The first method of making customizations is to directly edit the
templates found in <TT
CLASS="filename"
>template/en/default</TT
>.
This is probably the best way to go about it if you are going to
be upgrading Bugzilla through CVS, because if you then execute
a <B

>, any changes you have made will
be merged automagically with the updated versions.

>&#13; The second method of customization should be used if you
use the overwriting method of upgrade, because otherwise
your changes will be lost. This method may also be better if
you are using the CVS method of upgrading and are going to make major
changes, because it is guaranteed that the contents of this directory
will not be touched during an upgrade, and you can then decide whether
to continue using your own templates, or make the effort to merge your
changes into the new versions by hand.
</P
><P
>&#13; Using this method, your installation may break if incompatible
changes are made to the template interface. Such changes should
be documented in the release notes, provided you are using a
stable release of Bugzilla. If you use using unstable code, you will
need to deal with this one yourself, although if possible the changes
will be mentioned before they occur in the deprecations section of the
previous stable release's release notes.

>&#13; If you are making template changes that you intend on submitting back
for inclusion in standard Bugzilla, you should read the relevant
sections of the

>Developers'
Guide</A
>.
</P

><P
>&#13; The syntax of the Template Toolkit language is beyond the scope of
this guide. It's reasonably easy to pick up by looking at the current
templates; or, you can read the manual, available on the
<A
HREF="http://www.template-toolkit.org"
TARGET="_top"
>Template Toolkit home
page</A
>.
</P
><P
>&#13; One thing you should take particular care about is the need
to properly HTML filter data that has been passed into the template.
This means that if the data can possibly contain special HTML characters
such as &#60;, and the data was not intended to be HTML, they need to be
converted to entity form, i.e. &#38;lt;. You use the 'html' filter in the
Template Toolkit to do this. If you forget, you may open up
your installation to cross-site scripting attacks.
</P
><P
>&#13; Also note that Bugzilla adds a few filters of its own, that are not
in standard Template Toolkit. In particular, the 'url_quote' filter
can convert characters that are illegal or have special meaning in URLs,
such as &#38;, to the encoded form, i.e. %26. This actually encodes most
characters (but not the common ones such as letters and numbers and so
on), including the HTML-special characters, so there's never a need to
HTML filter afterwards.
</P
><P
>&#13; Editing templates is a good way of doing a <SPAN
CLASS="QUOTE"
>"poor man's custom
fields"</SPAN
>.
For example, if you don't use the Status Whiteboard, but want to have
a free-form text entry box for <SPAN
CLASS="QUOTE"
>"Build Identifier"</SPAN
>,
then you can just
edit the templates to change the field labels. It's still be called
status_whiteboard internally, but your users don't need to know that.

<TT
CLASS="filename"

formats of HTML (complex and simple). The mechanism that provides this
feature is extensible.
</P
><P
>&#13; Bugzilla can support different types of output, which again can have
multiple formats. In order to request a certain type, you can append
the &#38;ctype=&#60;contenttype&#62; (such as rdf or html) to the
<TT
CLASS="filename"
>&#60;cginame&#62;.cgi</TT

retrieve a certain format, you can use the &#38;format=&#60;format&#62;
(such as simple or complex) in the URL.
</P

>&#13; To see if a CGI supports multiple output formats and types, grep the
CGI for <SPAN

multiple format/type support isn't too hard - see how it's done in
other CGIs, e.g. config.cgi.

open a current template for
that CGI and take note of the INTERFACE comment (if present.) This
comment defines what variables are passed into this template. If
there isn't one, I'm afraid you'll have to read the template and
the code to find out what information you get.

served as. The content types are defined in the

the three- or four-letter tag assigned to your content type.

>&#13; There are a few templates you may be particularly interested in
customizing for your installation.
</P
><P
>&#13; <B
CLASS="command"
>index.html.tmpl</B
>:
This is the Bugzilla front page.
</P
><P
>&#13; <B
CLASS="command"
>global/header.html.tmpl</B
>:
This defines the header that goes on all Bugzilla pages.
The header includes the banner, which is what appears to users
and is probably what you want to edit instead. However the
header also includes the HTML HEAD section, so you could for
example add a stylesheet or META tag by editing the header.
</P
><P
>&#13; <B
CLASS="command"
>global/banner.html.tmpl</B
>:
This contains the <SPAN
CLASS="QUOTE"
>"banner"</SPAN
>, the part of the header
that appears
at the top of all Bugzilla pages. The default banner is reasonably
barren, so you'll probably want to customize this to give your
installation a distinctive look and feel. It is recommended you
preserve the Bugzilla version number in some form so the version
you are running can be determined, and users know what docs to read.
</P
><P
>&#13; <B
CLASS="command"
>global/footer.html.tmpl</B
>:
This defines the footer that goes on all Bugzilla pages. Editing
this is another way to quickly get a distinctive look and feel for
your Bugzilla installation.
</P
><P
>&#13; <B
CLASS="command"
>global/variables.none.tmpl</B
>:
This defines a list of terms that may be changed in order to
<SPAN
CLASS="QUOTE"
>"brand"</SPAN
> the Bugzilla instance In this way, terms
like <SPAN
CLASS="QUOTE"
>"bugs"</SPAN
> can be replaced with <SPAN
CLASS="QUOTE"
>"issues"</SPAN
>
across the whole Bugzilla installation. The name
<SPAN
CLASS="QUOTE"
>"Bugzilla"</SPAN
> and other words can be customized as well.
</P
><P
>&#13; <B
CLASS="command"
>list/table.html.tmpl</B
>:
This template controls the appearance of the bug lists created
by Bugzilla. Editing this template allows per-column control of
the width and title of a column, the maximum display length of
each entry, and the wrap behaviour of long entries.
For long bug lists, Bugzilla inserts a 'break' every 100 bugs by
default; this behaviour is also controlled by this template, and
that value can be modified here.
</P
><P
>&#13; <B
CLASS="command"
>bug/create/user-message.html.tmpl</B
>:
This is a message that appears near the top of the bug reporting page.
By modifying this, you can tell your users how they should report
bugs.
</P
><P
>&#13; <B
CLASS="command"
>bug/process/midair.html.tmpl</B
>:
This is the page used if two people submit simultaneous changes to the
same bug. The second person to submit their changes will get this page
to tell them what the first person did, and ask if they wish to
overwrite those changes or go back and revisit the bug. The default
title and header on this page read "Mid-air collision detected!" If
you work in the aviation industry, or other environment where this
might be found offensive (yes, we have true stories of this happening)
you'll want to change this to something more appropriate for your
environment.
</P
><P
>&#13; <B
CLASS="command"
>bug/create/create.html.tmpl</B
> and
<B
CLASS="command"
>bug/create/comment.txt.tmpl</B
>:
You may not wish to go to the effort of creating custom fields in
Bugzilla, yet you want to make sure that each bug report contains
a number of pieces of important information for which there is not
a special field. The bug entry system has been designed in an
extensible fashion to enable you to add arbitrary HTML widgets,
such as drop-down lists or textboxes, to the bug entry page
and have their values appear formatted in the initial comment.
A hidden field that indicates the format should be added inside
the form in order to make the template functional. Its value should
be the suffix of the template filename. For example, if the file
is called <TT
CLASS="filename"
>create-cust.html.tmpl</TT
>, then
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><FONT
COLOR="#000000"
><PRE
CLASS="programlisting"
>&#60;input type="hidden" name="format" value="cust"&#62;</PRE
></FONT
></TD
></TR
></TABLE
>
should be used inside the form.
</P
><P
>
An example of this is the mozilla.org
<A
HREF="http://landfill.bugzilla.org/bugzilla-tip/enter_bug.cgi?product=WorldControl&#38;format=guided"
TARGET="_top"
>guided
bug submission form</A
>. The code for this comes with the Bugzilla
distribution as an example for you to copy. It can be found in the
files
<TT
CLASS="filename"
>create-guided.html.tmpl</TT
> and
<TT
CLASS="filename"
>comment-guided.html.tmpl</TT
>.
</P
><P
>&#13; So to use this feature, create a custom template for
<TT
CLASS="filename"
>enter_bug.cgi</TT
>. The default template, on which you
could base it, is
<TT
CLASS="filename"
>custom/bug/create/create.html.tmpl</TT
>.
Call it <TT
CLASS="filename"
>create-&#60;formatname&#62;.html.tmpl</TT
>, and
in it, add widgets for each piece of information you'd like
collected - such as a build number, or set of steps to reproduce.
</P
><P
>&#13; Then, create a template like
<TT
CLASS="filename"
>custom/bug/create/comment.txt.tmpl</TT
>, and call it
<TT
CLASS="filename"
>comment-&#60;formatname&#62;.txt.tmpl</TT
>. This
template should reference the form fields you have created using
the syntax <TT
CLASS="filename"
>[% form.&#60;fieldname&#62; %]</TT
>. When a
bug report is
submitted, the initial comment attached to the bug report will be
formatted according to the layout of this template.
</P
><P
>&#13; For example, if your custom enter_bug template had a field
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><FONT
COLOR="#000000"
><PRE
CLASS="programlisting"
>&#60;input type="text" name="buildid" size="30"&#62;</PRE
></FONT
></TD

and then your comment.txt.tmpl had
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><FONT
COLOR="#000000"
><PRE
CLASS="programlisting"
>BuildID: [% form.buildid %]</PRE
></FONT

then something like
<TABLE

><FONT

>&#13; Template hooks are a way for extensions to Bugzilla to insert code
into the standard Bugzilla templates without modifying the template files
themselves. The hooks mechanism defines a consistent API for extending
the standard templates in a way that cleanly separates standard code
from extension code. Hooks reduce merge conflicts and make it easier
to write extensions that work across multiple versions of Bugzilla,
making upgrading a Bugzilla installation with installed extensions easier.
</P
><P
>&#13; A template hook is just a named place in a standard template file
where extension template files for that hook get processed. Each hook
has a corresponding directory in the Bugzilla directory tree. Hooking an
extension template to a hook is as simple as putting the extension file
into the hook's directory. When Bugzilla processes the standard template
and reaches the hook, it will process all extension templates in the
hook's directory. The hooks themselves can be added into any standard
template upon request by extension authors.
</P
><P
>&#13; To use hooks to extend a Bugzilla template, first make sure there is
a hook at the appropriate place within the template you want to extend.
Hooks appear in the standard Bugzilla templates as a single directive
in the format
<VAR
CLASS="literal"
>[% Hook.process("<VAR
CLASS="varname"
>name</VAR
>") %]</VAR
>,
where <VAR
CLASS="varname"
>name</VAR
> is the unique (within that template)
name of the hook.
</P
><P
>&#13; If you aren't sure which template you want to extend or just want
to browse the available hooks, either use your favorite multi-file search
tool (e.g. <B
CLASS="command"
>grep</B
>) to search the standard templates
for occurrences of <CODE
CLASS="methodname"
>Hook.process</CODE
> or browse
the directory tree in
<TT
CLASS="filename"
>BUGZILLA_ROOT/template/en/extension/hook/</TT
>,
which contains a directory for each hook in the following location:
</P
><P
>&#13; <TT
CLASS="filename"
>BUGZILLA_ROOT/template/en/extension/hook/PATH_TO_STANDARD_TEMPLATE/STANDARD_TEMPLATE_NAME/HOOK_NAME/</TT
>
</P
><P
>&#13; If there is no hook at the appropriate place within the Bugzilla template
you want to extend,
<A
HREF="http://bugzilla.mozilla.org/enter_bug.cgi?product=Bugzilla&#38;component=User%20Interface"
TARGET="_top"
>file

><P
>&#13; The Bugzilla reviewers will promptly review each hook request,
name the hook, add it to the template, check the new version
of the template into CVS, and create the corresponding directory in
<TT
CLASS="filename"
>BUGZILLA_ROOT/template/en/extension/hook/</TT
>.
</P
><P
>&#13; You may optionally attach a patch to the bug which implements the hook
and check it in yourself after receiving approval from a Bugzilla
reviewer. The developers may suggest changes to the location of the
hook based on their analysis of your needs or so the hook can satisfy
the needs of multiple extensions, but the process of getting hooks
approved and checked in is not as stringent as the process for general
changes to Bugzilla, and any extension, whether released or still in
development, can have hooks added to meet their needs.
</P
><P
>&#13; After making sure the hook you need exists (or getting it added if not),
add your extension template to the directory within the Bugzilla
directory tree corresponding to the hook.
</P
><P
>&#13; That's it! Now, when the standard template containing the hook
is processed, your extension template will be processed at the point
where the hook appears.
</P
><P
>&#13; For example, let's say you have an extension named Projman that adds
project management capabilities to Bugzilla. Projman has an
administration interface <TT
CLASS="filename"
>edit-projects.cgi</TT
>,
and you want to add a link to it into the navigation bar at the bottom
of every Bugzilla page for those users who are authorized
to administer projects.
</P

</P
><P
>&#13; Notes:
</P
><P
></P
><UL
><LI
><P
>&#13; You may want to prefix your extension template names
with the name of your extension, e.g.
<TT
CLASS="filename"
>projman-foo.html.tmpl</TT
>,
so they do not conflict with the names of templates installed by
other extensions.
</P
></LI
><LI
><P
>&#13; If your extension includes entirely new templates in addition to
extensions of standard templates, it should install those new
templates into an extension-specific subdirectory of the
<TT
CLASS="filename"
>BUGZILLA_ROOT/template/en/extension/</TT
>
directory. The <TT
CLASS="filename"
>extension/</TT
> directory, like the
<TT
CLASS="filename"
>default/</TT
> and <TT
CLASS="filename"
>custom/</TT
>
directories, is part of the template search path, so putting templates
there enables them to be found by the template processor.
</P
><P
>&#13; The template processor looks for templates first in the
<TT
CLASS="filename"
>custom/</TT
> directory (i.e. templates added by the
specific installation), then in the <TT
CLASS="filename"
>extension/</TT
>
directory (i.e. templates added by extensions), and finally in the
<TT
CLASS="filename"
>default/</TT
> directory (i.e. the standard Bugzilla
templates). Thus extension templates can override standard templates,
but installation-specific templates override both.
</P
><P
>&#13; Note that overriding standard templates with extension templates
gives you great power but also makes upgrading an installation harder.
As with custom templates, we recommend using this functionality
sparingly and only when absolutely necessary.
</P
></LI
><LI
><P
>&#13; Installation customizers can also take advantage of hooks when adding
code to a Bugzilla template. To do so, create directories in
<TT
CLASS="filename"
>BUGZILLA_ROOT/template/en/custom/hook/</TT
>
equivalent to the directories in
<TT
CLASS="filename"
>BUGZILLA_ROOT/template/en/extension/hook/</TT
>
for the hooks you want to use, then place your customization templates
into those directories.
</P
><P
>&#13; Obviously this method of customizing Bugzilla only lets you add code
to the standard templates; you cannot change the existing code.
Nevertheless, for those customizations that only add code, this method
can reduce conflicts when merging changes, making upgrading
your customized Bugzilla installation easier.

Bugzilla has been
designed to make it easy for you to write your own custom rules to define
who is allowed to make what sorts of value transition.
</P
><P
>&#13; For maximum flexibility, customizing this means editing Bugzilla's Perl
code. This gives the administrator complete control over exactly who is
allowed to do what. The relevant function is called
<TT
CLASS="filename"
>CheckCanChangeField()</TT
>,
and is found in <TT
CLASS="filename"
>process_bug.cgi</TT
> in your
Bugzilla directory. If you open that file and search for
<SPAN

</P
><P
>&#13; This function has been carefully commented to allow you to see exactly
how it works, and give you an idea of how to make changes to it.
Certain marked sections should not be changed - these are
the <SPAN
CLASS="QUOTE"

In between those sections, you'll find snippets of code like:
<TABLE

><FONT

}</PRE
></FONT

></TR
></TABLE
>
It's fairly obvious what this piece of code does.
</P
><P
>&#13; So, how does one go about changing this function? Well, simple changes
can be made just by removing pieces - for example, if you wanted to
prevent any user adding a comment to a bug, just remove the lines marked
<SPAN
CLASS="QUOTE"
>"Allow anyone to change comments."</SPAN
> If you don't want the
Reporter to have any special rights on bugs they have filed, just
remove the entire section that deals with the Reporter.
</P
><P
>&#13; More complex customizations are not much harder. Basically, you add
a check in the right place in the function, i.e. after all the variables
you are using have been set up. So, don't look at $ownerid before
$ownerid has been obtained from the database. You can either add a
positive check, which returns 1 (allow) if certain conditions are true,
or a negative check, which returns 0 (deny.) E.g.:

This says that only users in the group "quality_assurance" can change
the QA Contact field of a bug.

This says that if the user is trying to change the priority field,

>5.5. MySQL Bugzilla Database Introduction</A
></H2
><P
>This information comes straight from my life. I was forced to learn
how Bugzilla organizes database because of nitpicky requests from users
for tiny changes in wording, rather than having people re-educate
themselves or figure out how to work our procedures around the tool. It
sucks, but it can and will happen to you, so learn how the schema works
and deal with it when it comes.</P
><P
>So, here you are with your brand-new installation of Bugzilla.
You've got MySQL set up, Apache working right, Perl DBI and DBD talking
to the database flawlessly. Maybe you've even entered a few test bugs to
make sure email's working; people seem to be notified of new bugs and
changes, and you can enter and edit bugs to your heart's content. Perhaps
you've gone through the trouble of setting up a gateway for people to
submit bugs to your database via email, have had a few people test it,
and received rave reviews from your beta testers.</P
><P
>What's the next thing you do? Outline a training strategy for your
development team, of course, and bring them up to speed on the new tool
you've labored over for hours.</P
><P
>Your first training session starts off very well! You have a
captive audience which seems enraptured by the efficiency embodied in
this thing called "Bugzilla". You are caught up describing the nifty
features, how people can save favorite queries in the database, set them
up as headers and footers on their pages, customize their layouts,
generate reports, track status with greater efficiency than ever before,
leap tall buildings with a single bound and rescue Jane from the clutches
of Certain Death!</P
><P
>But Certain Death speaks up -- a tiny voice, from the dark corners
of the conference room. "I have a concern," the voice hisses from the
darkness, "about the use of the word 'verified'."</P
><P
>The room, previously filled with happy chatter, lapses into
reverential silence as Certain Death (better known as the Vice President
of Software Engineering) continues. "You see, for two years we've used
the word 'verified' to indicate that a developer or quality assurance
engineer has confirmed that, in fact, a bug is valid. I don't want to
lose two years of training to a new software product. You need to change
the bug status of 'verified' to 'approved' as soon as possible. To avoid
confusion, of course."</P
><P
>Oh no! Terror strikes your heart, as you find yourself mumbling
"yes, yes, I don't think that would be a problem," You review the changes
with Certain Death, and continue to jabber on, "no, it's not too big a
change. I mean, we have the source code, right? You know, 'Use the
Source, Luke' and all that... no problem," All the while you quiver
inside like a beached jellyfish bubbling, burbling, and boiling on a hot
Jamaican sand dune...</P
><P
>Thus begins your adventure into the heart of Bugzilla. You've been
forced to learn about non-portable enum() fields, varchar columns, and
tinyint definitions. The Adventure Awaits You!</P

&nbsp;&nbsp;Here's&nbsp;an&nbsp;overview&nbsp;of&nbsp;what&nbsp;each&nbsp;table&nbsp;does.&nbsp;Most&nbsp;columns&nbsp;in&nbsp;each&nbsp;table&nbsp;have<br>
descriptive&nbsp;names&nbsp;that&nbsp;make&nbsp;it&nbsp;fairly&nbsp;trivial&nbsp;to&nbsp;figure&nbsp;out&nbsp;their&nbsp;jobs.<br>
<br>
attachments:&nbsp;This&nbsp;table&nbsp;stores&nbsp;all&nbsp;attachments&nbsp;to&nbsp;bugs.&nbsp;It&nbsp;tends&nbsp;to&nbsp;be&nbsp;your<br>
largest&nbsp;table,&nbsp;yet&nbsp;also&nbsp;generally&nbsp;has&nbsp;the&nbsp;fewest&nbsp;entries&nbsp;because&nbsp;file<br>
attachments&nbsp;are&nbsp;so&nbsp;(relatively)&nbsp;large.<br>
<br>
bugs:&nbsp;&nbsp;This&nbsp;is&nbsp;the&nbsp;core&nbsp;of&nbsp;your&nbsp;system.&nbsp;The&nbsp;bugs&nbsp;table&nbsp;stores&nbsp;most&nbsp;of&nbsp;the<br>
current&nbsp;information&nbsp;about&nbsp;a&nbsp;bug,&nbsp;with&nbsp;the&nbsp;exception&nbsp;of&nbsp;the&nbsp;info&nbsp;stored&nbsp;in&nbsp;the<br>
other&nbsp;tables.<br>
<br>
bugs_activity:&nbsp;&nbsp;This&nbsp;stores&nbsp;information&nbsp;regarding&nbsp;what&nbsp;changes&nbsp;are&nbsp;made&nbsp;to&nbsp;bugs<br>

<br>
cc:&nbsp;&nbsp;This&nbsp;tiny&nbsp;table&nbsp;simply&nbsp;stores&nbsp;all&nbsp;the&nbsp;CC&nbsp;information&nbsp;for&nbsp;any&nbsp;bug&nbsp;which&nbsp;has<br>
any&nbsp;entries&nbsp;in&nbsp;the&nbsp;CC&nbsp;field&nbsp;of&nbsp;the&nbsp;bug.&nbsp;Note&nbsp;that,&nbsp;like&nbsp;most&nbsp;other&nbsp;tables&nbsp;in<br>
Bugzilla,&nbsp;it&nbsp;does&nbsp;not&nbsp;refer&nbsp;to&nbsp;users&nbsp;by&nbsp;their&nbsp;user&nbsp;names,&nbsp;but&nbsp;by&nbsp;their&nbsp;unique<br>
userid,&nbsp;stored&nbsp;as&nbsp;a&nbsp;primary&nbsp;key&nbsp;in&nbsp;the&nbsp;profiles&nbsp;table.<br>

translation&nbsp;to&nbsp;the&nbsp;actual&nbsp;field&nbsp;name&nbsp;"assigned_to"&nbsp;for&nbsp;entry&nbsp;into&nbsp;MySQL.<br>
<br>
groups:&nbsp;&nbsp;defines&nbsp;bitmasks&nbsp;for&nbsp;groups.&nbsp;A&nbsp;bitmask&nbsp;is&nbsp;a&nbsp;number&nbsp;that&nbsp;can&nbsp;uniquely<br>
identify&nbsp;group&nbsp;memberships.&nbsp;For&nbsp;instance,&nbsp;say&nbsp;the&nbsp;group&nbsp;that&nbsp;is&nbsp;allowed&nbsp;to<br>
tweak&nbsp;parameters&nbsp;is&nbsp;assigned&nbsp;a&nbsp;value&nbsp;of&nbsp;"1",&nbsp;the&nbsp;group&nbsp;that&nbsp;is&nbsp;allowed&nbsp;to&nbsp;edit<br>
users&nbsp;is&nbsp;assigned&nbsp;a&nbsp;"2",&nbsp;and&nbsp;the&nbsp;group&nbsp;that&nbsp;is&nbsp;allowed&nbsp;to&nbsp;create&nbsp;new&nbsp;groups&nbsp;is<br>
assigned&nbsp;the&nbsp;bitmask&nbsp;of&nbsp;"4".&nbsp;By&nbsp;uniquely&nbsp;combining&nbsp;the&nbsp;group&nbsp;bitmasks&nbsp;(much<br>
like&nbsp;the&nbsp;chmod&nbsp;command&nbsp;in&nbsp;UNIX,)&nbsp;you&nbsp;can&nbsp;identify&nbsp;a&nbsp;user&nbsp;is&nbsp;allowed&nbsp;to&nbsp;tweak<br>
parameters&nbsp;and&nbsp;create&nbsp;groups,&nbsp;but&nbsp;not&nbsp;edit&nbsp;users,&nbsp;by&nbsp;giving&nbsp;him&nbsp;a&nbsp;bitmask&nbsp;of<br>
"5",&nbsp;or&nbsp;a&nbsp;user&nbsp;allowed&nbsp;to&nbsp;edit&nbsp;users&nbsp;and&nbsp;create&nbsp;groups,&nbsp;but&nbsp;not&nbsp;tweak<br>
parameters,&nbsp;by&nbsp;giving&nbsp;him&nbsp;a&nbsp;bitmask&nbsp;of&nbsp;"6"&nbsp;Simple,&nbsp;huh?<br>
&nbsp;&nbsp;If&nbsp;this&nbsp;makes&nbsp;no&nbsp;sense&nbsp;to&nbsp;you,&nbsp;try&nbsp;this&nbsp;at&nbsp;the&nbsp;mysql&nbsp;prompt:<br>
mysql&#62;&nbsp;select&nbsp;*&nbsp;from&nbsp;groups;<br>

housecleaning&nbsp;--&nbsp;I&nbsp;see&nbsp;cookies&nbsp;in&nbsp;this&nbsp;file&nbsp;I've&nbsp;not&nbsp;used&nbsp;for&nbsp;months.&nbsp;However,<br>
since&nbsp;Bugzilla&nbsp;never&nbsp;expires&nbsp;your&nbsp;cookie&nbsp;(for&nbsp;convenience'&nbsp;sake),&nbsp;it&nbsp;makes<br>
sense.<br>
<br>
longdescs:&nbsp;&nbsp;The&nbsp;meat&nbsp;of&nbsp;bugzilla&nbsp;--&nbsp;here&nbsp;is&nbsp;where&nbsp;all&nbsp;user&nbsp;comments&nbsp;are&nbsp;stored!<br>

would&nbsp;take&nbsp;(uncompressed,&nbsp;16&nbsp;megabytes).&nbsp;Each&nbsp;comment&nbsp;is&nbsp;keyed&nbsp;to&nbsp;the<br>
bug_id&nbsp;to&nbsp;which&nbsp;it's&nbsp;attached,&nbsp;so&nbsp;the&nbsp;order&nbsp;is&nbsp;necessarily&nbsp;chronological,&nbsp;for<br>
comments&nbsp;are&nbsp;played&nbsp;back&nbsp;in&nbsp;the&nbsp;order&nbsp;in&nbsp;which&nbsp;they&nbsp;are&nbsp;received.<br>
<br>
milestones:&nbsp;&nbsp;Interesting&nbsp;that&nbsp;milestones&nbsp;are&nbsp;associated&nbsp;with&nbsp;a&nbsp;specific&nbsp;product<br>
in&nbsp;this&nbsp;table,&nbsp;but&nbsp;Bugzilla&nbsp;does&nbsp;not&nbsp;yet&nbsp;support&nbsp;differing&nbsp;milestones&nbsp;by<br>
product&nbsp;through&nbsp;the&nbsp;standard&nbsp;configuration&nbsp;interfaces.<br>
<br>
namedqueries:&nbsp;&nbsp;This&nbsp;is&nbsp;where&nbsp;everybody&nbsp;stores&nbsp;their&nbsp;"custom&nbsp;queries".&nbsp;Very<br>

50,000&nbsp;bugs&nbsp;play&nbsp;across&nbsp;your&nbsp;screen.<br>

&nbsp;&nbsp;You&nbsp;can&nbsp;limit&nbsp;the&nbsp;display&nbsp;from&nbsp;above&nbsp;a&nbsp;little&nbsp;with&nbsp;the&nbsp;command,&nbsp;where<br>

change,&nbsp;but&nbsp;I&nbsp;won't&nbsp;plunge&nbsp;into&nbsp;that&nbsp;in&nbsp;this&nbsp;document.&nbsp;Let's&nbsp;verify&nbsp;the<br>

"http://www.bugzilla.org" will be turned into a link:

>If you are changing the fields on a bug, only comment if
either you have something pertinent to say, or Bugzilla requires it.
Otherwise, you may spam people unnecessarily with bug mail.
To take an example: a user can set up their account to filter out messages
where someone just adds themselves to the CC field of a bug
(which happens a lot.) If you come along, add yourself to the CC field,
and add a comment saying "Adding self to CC", then that person
gets a pointless piece of mail they would otherwise have avoided.
</P

if you do it out of habit, but full mail/news-style
four line ASCII art creations are not.

><P
>&#13; Use attachments, rather than comments, for large chunks of ASCII data,
such as trace, debugging output files, or log files. That way, it doesn't
bloat the bug for everyone who wants to read it, and cause people to
receive fat, useless mails.
</P
><P
>Trim screenshots. There's no need to show the whole screen if
you are pointing out a single-pixel problem.
</P
><P
>Don't attach simple test cases (e.g. one HTML file, one
CSS file and an image) as a ZIP file. Instead, upload them in
reverse order and edit the referring file so that they point to the
attached files. This way, the test case works immediately
out of the bug.
</P
><P
>Bugzilla stores and uses a Content-Type for each attachment
(e.g. text/html). To download an attachment as a different
Content-Type (e.g. application/xhtml+xml), you can override this
using a 'content-type' parameter on the URL, e.g.
<TT
CLASS="filename"
>&#38;content-type=text/plain</TT
>.
</P
><P
>&#13; If you have a really large attachment, something that does not need to
be recorded forever (as most attachments are), you can mark your
attachment as a Big File, Assuming the administrator of the
installation has enabled this feature. Big Files are stored directly on
disk instead of in the database, and can be deleted when it is no longer
needed. The maximum size of a Big File is normally larger than the
maximum size of a regular attachment.

line/pie/bar-chart-based one. The two have different pages to
define them, but are close cousins - once you've defined and
viewed a report, you can switch between any of the different
views of the data at will.
</P
><P
>&#13; Both report types are based on the idea of defining a set of bugs
using the standard search interface, and then choosing some
aspect of that set to plot on the horizontal and/or vertical axes.
You can also get a form of 3-dimensional report by choosing to have
multiple images or tables.
</P

>&#13; So, for example, you could use the search form to choose "all
bugs in the WorldControl product", and then plot their severity
against their component to see which component had had the largest
number of bad bugs reported against it.

you can switch between HTML, CSV, Bar, Line and Pie. (Note: Pie
is only available if you didn't define a vertical axis, as pie

>&#13; Whining is a feature in Bugzilla that can regularly annoy users at
specified times. Using this feature, users can execute saved searches
at specific times (i.e. the 15th of the month at midnight) or at
regular intervals (i.e. every 15 minutes on Sundays). The results of the
searches are sent to the user, either as a single email or as one email
per bug, along with some descriptive text.

>&#13; The whining system defines an "Event" as one or more queries being
executed at regular intervals, with the results of said queries (if
there are any) being emailed to the user. Events are created by
clicking on the "Add new event" button.
</P
><P
>&#13; Once a new event is created, the first thing to set is the "Email
subject line". The contents of this field will be used in the subject
line of every email generated by this event. In addition to setting a
subject, space is provided to enter some descriptive text that will be
included at the top of each message (to help you in understanding why
you received the email in the first place).
</P
><P
>&#13; The next step is to specify when the Event is to be run (the Schedule)
and what searches are to be performed (the Queries).

></H3
><P
>&#13; Each whining event is associated with zero or more schedules. A
schedule is used to specify when the query (specified below) is to be
run. A new event starts out with no schedules (which means it will
never run, as it is not scheduled to run). To add a schedule, press
the "Add a new schedule" button.
</P
><P
>&#13; Each schedule includes an interval, which you use to tell Bugzilla
when the event should be run. An event can be run on certain days of
the week, certain days of the month, during weekdays (defined as
Monday through Friday), or every day.

every hour, half-hour, or quarter-hour on the specified day(s).
</P
><P
>&#13; If a single schedule does not execute an event as many times as you
would want, you can create another schedule for the same event. For
example, if you want to run an event on days whose numbers are
divisible by seven, you would need to add four schedules to the event,
setting the schedules to run on the 7th, 14th, 21st, and 28th (one day
per schedule) at whatever time (or times) you choose.

saved yourself (the default saved search, "My Bugs", is not a valid

We can't find any head-to-head comparisons of Bugzilla against
other defect-tracking software. If you know of one, please get
in touch. In the experience of Matthew Barnson (the original
author of this FAQ), though, Bugzilla offers superior
performance on commodity hardware, better price (free!), more
developer-friendly features (such as stored queries, email
integration, and platform independence), improved scalability,
greater flexibility, and superior ease-of-use when compared
to commercial bug-tracking software.
</P

software, and would like to submit a list of advantages your

It may be that the support has not been built yet, or that you
have not yet found it. While Bugzilla makes strides in usability,
customizability, scalability, and user interface with each release,
that doesn't mean it can't still use improvement!

>&#13; The best way to make an enhancement request is to <A
HREF="http://bugzilla.mozilla.org/enter_bug.cgi?product=Bugzilla"
TARGET="_top"

a bug at bugzilla.mozilla.org</A
> and set the Severity
to 'enhancement'. Your 'request for enhancement' (RFE) will
start out in the UNCONFIRMED state, and will stay there until
someone with the ability to COMFIRM the bug reviews it.
If that person feels it to be a good request that fits in with
Bugzilla's overall direction, the status will be changed to
NEW; if not, they will probably explain why and set the bug
to RESOLVED/WONTFIX. If someone else has made the same (or
almost the same) request before, your request will be marked
RESOLVED/DUPLICATE, and a pointer to the previous RFE will be
added.
</P
><P
>&#13; Even if your RFE gets approved, that doesn't mean it's going
to make it right into the next release; there are a limited
number of developers, and a whole lot of RFEs... some of

happens, it's VERY unlikely to work without the end-user-company

Sybase is just NOT very standards-compliant (despite all the hype),
and it turned out that way too much had to be changed to make it
work -- like moving half of the application logic into stored
procedures to get any kind of decent performance out of it.

Bugzilla used to have the path to perl on the shebang line set
to <TT

>/usr/bonsaitools/bin/perl</TT

Terry first started writing the code for mozilla.org he needed a
version of Perl and other tools that were completely under his
control. This location was abandoned for the 2.18 release in favor
of the more sensible <TT

>/usr/bin/perl</TT

installed an older verion of Bugzilla and created the symlink we
suggested, you can remove it now (provided that you don't have
anything else, such as Bonsai, using it and you don't intend to
reinstall an older version of Bugzilla).

If that's not an option for you, the following bit of perl

the line at the top of each file that starts with '#!'

Bugzilla can output buglists as HTML (the default), CSV or RDF.

format. This CSV format can easily be imported into MS Excel or

is meant to be machine readable and thus it is assumed that the
URL would be generated programmatically so there is no user visible

It all depends on your level of commitment. Someone with much
Bugzilla experience can get you up and running in less than a day,
and your Bugzilla install can run untended for years. If your
Bugzilla strategy is critical to your business workflow, hire
somebody to who has reasonable Perl skills, and a familiarity
with the operating system on which Bugzilla will be running,
and have them handle your process management, bug-tracking
maintenance, and local customization.

No. Bugzilla, Perl, the Template Toolkit, and all other support

Bugzilla does not lock records. It provides mid-air collision

about to conflict with commits recently made by another user,
and offers the second user a choice of options to deal with
the conflict.

Yes, but commits to the database must wait until the tables
are unlocked. Bugzilla databases are typically very small,
and backups routinely take less than a minute. If your database
is larger, you may want to look into alternate backup
techniques, such as database replication, or backing up from
a read-only mirror. (Read up on these in the MySQL docs
on the MySQL site.)

To use the UNCONFIRMED status, you must have the 'usevotes'

Number of votes a bug in this product needs to automatically
get out of the UNCONFIRMED state"</SPAN

(You will have to do this for each product that wants to use
the UNCONFIRMED state.) If you do not actually want users to be
able to vote for bugs entered against this product, leave the
<SPAN
CLASS="QUOTE"
>"Maximum votes per person"</SPAN
> value at '0'.
</P
><P
>&#13; There is work being done to decouple the UNCONFIRMED state from
the 'usevotes' parameter for future versions of Bugzilla.

The Bugzilla code has undergone a reasonably complete security
audit, and user-facing CGIs run under Perl's taint mode. However,
it is recommended that you closely examine permissions on your
Bugzilla installation, and follow the recommended security
guidelines found in The Bugzilla Guide.

The user can stop Bugzilla from sending any mail by unchecking
all boxes on the 'Edit prefs' -&#62; 'Email settings' page.
(As of 2.18,this is made easier by the addition of a 'Disable
All Mail' button.) Alternately, you can add their email address
to the <TT
CLASS="filename"
>data/nomail</TT

per line). This will override their personal preferences, and
they will never be sent mail again.

There is no facility in Bugzilla itself to do this. It's also
generally not a smart thing to do if you don't know exactly what
you're doing. If you understand SQL, though, you can use the
<B

delete and modify table information. There are also more intuitive
GUI clients available. Personal favorites of the Bugzilla team

Try running MySQL from its binary:

This will allow you to completely rule out grant tables as the
cause of your frustration. If this Bugzilla is able to connect
at this point then you need to check that you have granted proper
permission to the user password combo defined in
<TT

Well, you can synchronize or you can move bugs.
Synchronization will only work one way -- you can create
a read-only copy of the database at one site, and have it
regularly updated at intervals from the main database.
</P
><P
>&#13; MySQL has some synchronization features built-in to the
latest releases. It would be great if someone looked into
the possibilities there and provided a report to the
newsgroup on how to effectively synchronize two Bugzilla
installations.

Not currently. Bundle::Bugzilla enormously simplifies Bugzilla
installation on UNIX systems. If someone can volunteer to
create a suitable PPM bundle for Win32, it would be appreciated.

Depending on what Web server you are using, you will have to
configure the Web server to treat *.cgi files as CGI scripts.
In IIS, you do this by adding *.cgi to the App Mappings with
the &#60;path&#62;\perl.exe %s %s as the executable.

Note For the ActiveState Perl script interpreter, the extension
'.pl' is associated with PerlIS.dll by default. If you want
to change the association of .pl to perl.exe, you need to
change the application mapping. In the mapping, you must add
two percent (%) characters to the end of the pathname for
perl.exe, as shown in this example:

Simple answer; you can.
</P
><P
>&#13; The logic behind the page checks every bug in the list to
determine legal state changes, and then only shows you controls
to do things that could apply to <EM
>every</EM
> bug
on the list. The reason for this is that if you try to do something
illegal to a bug, the whole process will grind to a halt, and all
changes after the failed one will <EM
>also</EM
> fail.
Since that isn't a good outcome, the page doesn't even present
you with the option.
</P
><P
>&#13; In practical terms, that means that in order to mark
multiple bugs as CLOSED, then every bug on the page has to be
either RESOLVED or VERIFIED already; if this is not the case,
then the option to close the bugs will not appear on the page.
</P
><P
>&#13; The rationale is that if you pick one of the bugs that's not
VERIFIED and try to CLOSE it, the bug change will fail
miserably (thus killing any changes in the list after it
while doing the bulk change) so it doesn't even give you the
choice.

the cookiepath set to "/", or to a sufficiently-high enough directory that
all of the involved apps can see the cookies.

implements a rotating proxy server. This causes the user's effective IP

address, each time the effective address changes, the user will have to
log in again.

parameter called <SPAN

the number of bits of the user's IP address to require to be matched when
authenticating the cookies. If you set this to something less than 32,
then the user will be given a checkbox for <SPAN
CLASS="QUOTE"
>"Restrict this login to
my IP address"</SPAN
> on the login screen, which defaults to checked. If
they leave the box checked, Bugzilla will behave the same as it did
before, requiring an exact match on their IP address to remain logged in.
If they uncheck the box, then only the left side of their IP address (up
to the number of bits you specified in the parameter) has to match to
remain logged in.

>The purpose of this License is to make a manual, textbook, or other
written document "free" in the sense of freedom: to assure everyone the
effective freedom to copy and redistribute it, with or without modifying
it, either commercially or noncommercially. Secondarily, this License
preserves for the author and publisher a way to get credit for their
work, while not being considered responsible for modifications made by
others.</P
><P
>This License is a kind of "copyleft", which means that derivative
works of the document must themselves be free in the same sense. It
complements the GNU General Public License, which is a copyleft license
designed for free software.</P
><P
>We have designed this License in order to use it for manuals for
free software, because free software needs free documentation: a free
program should come with manuals providing the same freedoms that the
software does. But this License is not limited to software manuals; it
can be used for any textual work, regardless of subject matter or whether
it is published as a printed book. We recommend this License principally
for works whose purpose is instruction or reference.</P

NAME="gfdl-1"
>1. Applicability and Definition</A
></H2
><P
>This License applies to any manual or other work that contains a
notice placed by the copyright holder saying it can be distributed under
the terms of this License. The "Document", below, refers to any such
manual or work. Any member of the public is a licensee, and is addressed
as "you".</P
><P
>A "Modified Version" of the Document means any work containing the
Document or a portion of it, either copied verbatim, or with
modifications and/or translated into another language.</P
><P
>A "Secondary Section" is a named appendix or a front-matter section
of the Document that deals exclusively with the relationship of the
publishers or authors of the Document to the Document's overall subject
(or to related matters) and contains nothing that could fall directly
within that overall subject. (For example, if the Document is in part a
textbook of mathematics, a Secondary Section may not explain any
mathematics.) The relationship could be a matter of historical connection
with the subject or with related matters, or of legal, commercial,
philosophical, ethical or political position regarding them.</P
><P
>The "Invariant Sections" are certain Secondary Sections whose
titles are designated, as being those of Invariant Sections, in the
notice that says that the Document is released under this License.</P
><P
>The "Cover Texts" are certain short passages of text that are
listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says
that the Document is released under this License.</P
><P
>A "Transparent" copy of the Document means a machine-readable copy,
represented in a format whose specification is available to the general
public, whose contents can be viewed and edited directly and
straightforwardly with generic text editors or (for images composed of
pixels) generic paint programs or (for drawings) some widely available
drawing editor, and that is suitable for input to text formatters or for
automatic translation to a variety of formats suitable for input to text
formatters. A copy made in an otherwise Transparent file format whose
markup has been designed to thwart or discourage subsequent modification
by readers is not Transparent. A copy that is not "Transparent" is called
"Opaque".</P
><P
>Examples of suitable formats for Transparent copies include plain
ASCII without markup, Texinfo input format, LaTeX input format, SGML or
XML using a publicly available DTD, and standard-conforming simple HTML
designed for human modification. Opaque formats include PostScript, PDF,
proprietary formats that can be read and edited only by proprietary word
processors, SGML or XML for which the DTD and/or processing tools are not
generally available, and the machine-generated HTML produced by some word
processors for output purposes only.</P
><P
>The "Title Page" means, for a printed book, the title page itself,
plus such following pages as are needed to hold, legibly, the material
this License requires to appear in the title page. For works in formats
which do not have any title page as such, "Title Page" means the text
near the most prominent appearance of the work's title, preceding the
beginning of the body of the text.</P

>2. Verbatim Copying</A
></H2
><P
>You may copy and distribute the Document in any medium, either
commercially or noncommercially, provided that this License, the
copyright notices, and the license notice saying this License applies to
the Document are reproduced in all copies, and that you add no other
conditions whatsoever to those of this License. You may not use technical
measures to obstruct or control the reading or further copying of the
copies you make or distribute. However, you may accept compensation in
exchange for copies. If you distribute a large enough number of copies
you must also follow the conditions in section 3.</P
><P
>You may also lend copies, under the same conditions stated above,
and you may publicly display copies.</P

>3. Copying in Quantity</A
></H2
><P
>If you publish printed copies of the Document numbering more than
100, and the Document's license notice requires Cover Texts, you must
enclose the copies in covers that carry, clearly and legibly, all these
Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts
on the back cover. Both covers must also clearly and legibly identify you
as the publisher of these copies. The front cover must present the full
title with all words of the title equally prominent and visible. You may
add other material on the covers in addition. Copying with changes
limited to the covers, as long as they preserve the title of the Document
and satisfy these conditions, can be treated as verbatim copying in other
respects.</P
><P
>If the required texts for either cover are too voluminous to fit
legibly, you should put the first ones listed (as many as fit reasonably)
on the actual cover, and continue the rest onto adjacent pages.</P
><P
>If you publish or distribute Opaque copies of the Document
numbering more than 100, you must either include a machine-readable
Transparent copy along with each Opaque copy, or state in or with each
Opaque copy a publicly-accessible computer-network location containing a
complete Transparent copy of the Document, free of added material, which
the general network-using public has access to download anonymously at no
charge using public-standard network protocols. If you use the latter
option, you must take reasonably prudent steps, when you begin
distribution of Opaque copies in quantity, to ensure that this
Transparent copy will remain thus accessible at the stated location until
at least one year after the last time you distribute an Opaque copy
(directly or through your agents or retailers) of that edition to the
public.</P
><P
>It is requested, but not required, that you contact the authors of
the Document well before redistributing any large number of copies, to
give them a chance to provide you with an updated version of the
Document.</P

under the conditions of sections 2 and 3 above, provided that you release
the Modified Version under precisely this License, with the Modified
Version filling the role of the Document, thus licensing distribution and
modification of the Modified Version to whoever possesses a copy of it.
In addition, you must do these things in the Modified Version:</P

permission.</P

>Preserve the section entitled "History", and its title, and add
to it an item stating at least the title, year, new authors, and
publisher of the Modified Version as given on the Title Page. If
there is no section entitled "History" in the Document, create one
stating the title, year, authors, and publisher of the Document as
given on its Title Page, then add an item describing the Modified
Version as stated in the previous sentence.</P

>Preserve the network location, if any, given in the Document
for public access to a Transparent copy of the Document, and likewise
the network locations given in the Document for previous versions it
was based on. These may be placed in the "History" section. You may
omit a network location for a work that was published at least four
years before the Document itself, or if the original publisher of the
version it refers to gives permission.</P

preserve the section's title, and preserve in the section all the
substance and tone of each of the contributor acknowledgements and/or
dedications given therein.</P

in their text and in their titles. Section numbers or the equivalent
are not considered part of the section titles.</P

not be included in the Modified Version.</P

conflict in title with any Invariant Section.</P

></OL
><P
>If the Modified Version includes new front-matter sections or
appendices that qualify as Secondary Sections and contain no material
copied from the Document, you may at your option designate some or all of
these sections as invariant. To do this, add their titles to the list of
Invariant Sections in the Modified Version's license notice. These titles
must be distinct from any other section titles.</P
><P
>You may add a section entitled "Endorsements", provided it contains
nothing but endorsements of your Modified Version by various parties--for
example, statements of peer review or that the text has been approved by
an organization as the authoritative definition of a standard.</P
><P
>You may add a passage of up to five words as a Front-Cover Text,
and a passage of up to 25 words as a Back-Cover Text, to the end of the
list of Cover Texts in the Modified Version. Only one passage of
Front-Cover Text and one of Back-Cover Text may be added by (or through
arrangements made by) any one entity. If the Document already includes a
cover text for the same cover, previously added by you or by arrangement
made by the same entity you are acting on behalf of, you may not add
another; but you may replace the old one, on explicit permission from the
previous publisher that added the old one.</P

License give permission to use their names for publicity for or to assert
or imply endorsement of any Modified Version.</P
