2.18 has not been released yet - these are prerelease notes.
Insert nice little intro for version 2.18 here.
**************************
*** ABOUT THIS VERSION ***
**************************
This is a development snapshot release of Bugzilla. As such the remainder of
these release notes have NOT been updated (we usually do this just prior to a
stable release). For information about a development snapshot release, the
best source of information is on our website (http://www.bugzilla.org/) in
the Status Updates area. Development snapshot releases are NOT recommended
for production use unless you have an expert Perl programmer on hand willing
to combat any difficulties you run into, since there is no guarantee of
stability during a development cycle. You have been warned.
Bug numbers referenced in this document are all on
bugzilla.mozilla.org unless otherwise specified.
*** Recommended Practice For The Upgrade ***
As always, please ensure you have run checksetup.pl after
replacing the files in your installation.
It is recommended that you view the sanity check page
(sanitycheck.cgi) both before the upgrade and after running
checksetup.pl after the upgrade, to see if there are any
problems with your installation.
It is also recommended that if you can, you immediately fix
any problems you find. Be aware that if the sanity check page
contains more errors after an upgrade, it doesn't necessarily
mean there are more errors in your database, as additional
tests are added to the sanity check over time, and it is likely
those errors weren't being checked for in the old version.
Failure to do this may mean that bugzilla will not
work correctly.
Administrators must make sure that certain files are
inaccessible or confidential information might become
available to enterprising individuals. This includes the
localconfig file and the entire data directory. Please
see the Bugzilla Guide for more information.
*** Dependency Requirements ***
MySQL v3.23.41
Perl v5.6.0
CGI v2.88
DBI v1.32
DBD::mysql v2.1010
AppConfig v1.52
Template Toolkit v2.08
Text::Wrap v2001.0131
File::Spec v0.82
Date::Format v2.21
Data::Dumper, File::Temp, CGI::Carp (any)
GD v1.20 (optional)
GD::Text::Align (any, optional)
GD::Graph (any, optional)
Chart::Base v0.99 (optional)
XML::Parser (any, optional)
*** Deprecated Features ***
- (already happened - move this in 2.18 notes) This is
possibly the last stable release that will work with
MySQL version 3.22. Soon Bugzilla will require at least
version 3.23.x. The exact minimum version number required
has not yet been decided.
(bug 87958)
- (already happened - move this in 2.18 notes) This is
possibly the last stable release to support the
shadow database. The replacement (using MySQL's built in
replication) is not present in 2.16, but we expect that
very few sites use this feature, so we are not planning a
transition period. If this would cause a problem for you,
please comment on the below bug.
(bug 124589)
- Placing comments in localconfig is deprecated. If you have done
this, they will likely get nuked with future version of
Bugzilla, as checksetup.pl will likely automatically rewrite localconfig
to automatically get the latest comments.
(bug 147776)
*** Outstanding Issues Of Note ***
These issues may have been fixed in later stable or development
versions of Bugzilla. If you are interested in tracking these
bugs, please see the bug report numbers listed to find out the
status of the fix for these bugs, or to obtain a patch that can
fix the problem on your installation.
- Renaming or removing keywords that are in use will not update
the "keyword cache" on bugs, and queries on keywords may not work
properly, until you rebuild the cache on the sanity check page
(sanitycheck.cgi). The changer will receive a warning to do
this when altering the keyword.
(bug 69621)
- Email notifications will not work out of the box if you are
using Postfix, Exim or possibly other non-SendMail mail
transfer agents, as Bugzilla sends mail by default in
"deferred" mode using the "-ODeliveryMode=deferred" command
line option, which needs to be supported by the sendmail
program. To fix this, you can turn on the "sendmailnow"
parameter on the Edit Parameters page (editparams.cgi).
(bug 37765)
- Users behind rotating transparent proxies or otherwise having
an IP that changes each URL fetch will find they need to log in
regularly.
(bug 20122)
- If you search on any CC or added comments, as well as at least
one other of CC, added comments, assignee, reporter, etc, then
the search can be very slow. This is because of limitations of
the MySQL optimiser.
(bug 96101)
- It is recommended you use the high speed XS Stash of the Template
Toolkit, in order to achieve best performance. However, there are
known problems with XS Stash and Perl 5.005_02 and lower. If you
wish to use these older versions of Perl, please use the regular
stash. You are asked which stash you want to use at Template Toolkit
installation time.
(bug 140674)
- Querying on CC takes too long on big databases.
(bug 127200)
- Attachment changes have no midair collision detection, unlike bug changes.
(bug 99215)
- The email preferences option "Priority, status, severity, and/or milestone
changes" does not actually report status changes. You can however use the
option "The bug is resolved or verified" to achieve part of this.
(bug 130821)

- Fixed a cross site scriptability issue in quips. This is only a problem
if quips with HTML could have been inserted into your quips files. Bugzilla
has not allowed this since 2.12.
(bug 179329)
- checksetup.pl will now attempt to prevent access to "editor backups" of
localconfig.
(bug 186383)
- collectstats.pl no longer makes data/mining (which contains graphing
information) world writeable.
(bug 183188)

exploitable.
(bug 165221)
See also next major section.
*** Bug fixes of note ***
- The VERSION cookie which allowed the previously entered version of a product
to be remembered was not correctly set. It was only set as a session
cookie, and under some circumstances could interfere with other cookies
(such as the login information) send at the same time.
(bug 160227)
- importxml.pl would fail if the versioncache needed to be updated.
(bug 164464)
- Bug changes going through intermediate pages would munge fields with
multiple fields, such as CCs.
(bug 161203)
- On failure in template->new, Bugzilla will now die rather than futilely
attempt to use an error template.
(bug 166023)
- Fixed a problem where checksetup had problems converting old installations
that didn't have a duplicates table.
(bug 151619)
- Fixed a problem that caused taint errors when viewing or editing user
preferences with Perl 5.005 and Template 2.08.

******************************************************
*** SECURITY ISSUES RESOLVED ***
- When a new product is added to an installation with 47 groups or more and
"usebuggroups" is enabled, the new group will be assigned a groupset bit
using Perl math that is not exact beyond 2^48. This results in the new
group being defined with a "bit" that has several bits set. As users are
given access to the new group, those users will also gain access to
spurious lower group privileges. Also, group bits were not always reused
when groups were deleted.
(bug 167485)

*** The Bugzilla 2.18 Release Notes ***
***************************************
Introduction
************
This document contains the release notes for Bugzilla 2.18. In this document
recently added, changed, and removed features of Bugzilla are described.
The 2.18 release is the first in a new stable series, containing the results
of over two years of hard and dedicated work by volunteers all over the world
under the lead of Dave Miller.
This is a preliminary document detailing how we expect things to be in the
final 2.18 release. The contents of this document are subject to change up
until the final release. Please file bugs in Bugzilla for any additions or
corrections needed in this document.
- The email interface had another insecure single parameter system call. This
could potentially allow arbitrary shell commands to be run. This file is
not supported at this time, but as long as we knew about the problem, we
couldn't overlook it.
(bug 163024)
*** Bug fixes of note ***
- The email interface was broken. This was a 2.14.3 regression. This file
is not supported at this time, but as long as we knew about the problem, we
couldn't overlook it.
(bug 160631)
Dependency Requirements
-----------------------
Minimum software requirements:
MySQL v3.23.41 (changed from 2.16)
Perl v5.6.0 (changed from 2.16)
***********************************************
*** USERS UPGRADING FROM 2.14.5 OR EARLIER ***
***********************************************
*** SECURITY ISSUES RESOLVED ***
- The bug reporter could set the priority even when
'letsubmitterchoosepriority' was off.
(bug 63018)
- Most CGIs are now templatised. This helps to make it
easier to remember to HTML filter values and easier to spot
when they are not, preventing cross site scripting attacks.
(bug 86168)
- Most CGIs now run in taint mode. This helps to prevent
failure to validate errors.
(bug 108982)
*** IMPORTANT CHANGES ***
- 2.16 introduces "templatisation", a new feature that allows
administrators to easily customise the HTML output (the "look and feel")
of Bugzilla without altering Perl code. Bugzilla uses the
"Template Toolkit" for this. Please see the "Template Customisation"
section of the Bugzilla Guide for more details.
Administrators who ran the 2.15 development version and customised
templates should check the templates are still valid, as file names
and file paths have changed.
Most output is now templatised. This process will be complete next
milestone.
For speed, compiled templates are cached on disk. If you modify the
templates, the toolkit will normally detect the changes, and recompile the
changed templates.
Adding new directories anywhere inside the template directory may cause
permission errors if you don't have a webservergroup specified in
localconfig. If you see these, rerun checksetup.pl as root. If you do not
have root access, or cannot get someone who does to do this for you, you can
rename the data/template directory to data/template.old (or any other name
Bugzilla doesn't use). Then rerun checksetup.pl to regenerate the compiled
templates.
(bug 86168, 97832)
- Administrators can now configure maximum attachment sizes. These
should remain below the maximum size for your MySQL server, or you
will get obscure MySQL errors if you attach a bigger attachment.
To find out the current size attachment that MySQL can accept, type
the command 'mysqladmin variables' and find out the value of the
'max_allowed_packet' varible in bytes.
To change the maximum size that MySQL can accept you can alter this
variable in your 'my.cnf' file.
(bug 91664)
- Perl 5.004 is no longer supported because the Template Toolkit
requires 5.005.
(bug 97721)
- New module requirements: Text::Wrap, Template [requires AppConfig],
File::Spec.
(bugs 97784, 84338, 103778)
- The index page is now a CGI instead of an HTML page. You should remove
any existing index.html file and make sure your web server allows index.cgi
to be the default page in a directory. If you are not able to do that you
can instead set index_html in the 'localconfig' file to 1 and checksetup.pl
will create a redirect page for you.
(bug 80183)
- It is now recommended that administrators run "processmail rescanall"
after upgrading to 2.16 or beyond.
This will send out notification emails for changes that were
made but not emailed, due to Bugzilla bugs. All known
causes of this have been fixed in this version (bug 104589 and 99519).
It is also recommended that this be run nightly to avoid
lengthy delays in future if this problem reoccurs.
(bug 106377)
- In parallel with templatisation, a lot of changes have been made to the HTML
output of the Bugzilla CGIs. This could break code that attempts to parse
such code. For example, this breaks mozbot.
(no bug number)
- The "HTML template" parameters (headerhtml, bodyhtml, footerhtml,
errorhtml, bannerhtml, blurbhtml, mostfreqhtml, entryheaderhtml) have now
been moved to Template Toolkit templates. If you have modified these
parameters you will need to make corresponding changes to the corresponding
templates. Your old parameter values will be moved to a file called
old-params.txt by checksetup.pl.
The old parameters correspond to files in template/en/default as follows:
headerhtml: global/header.html.tmpl
footerhtml: global/footer.html.tmpl
bannerhtml: global/banner.html.tmpl
blurbhtml: global/banner.html.tmpl
mostfreqhtml: reports/duplicates*.html.tmpl
entryheaderhtml: bug/create/user-message.html.tmpl
(bug 140437)
*** Other changes of note ***
- The query page has been redesigned for better user friendliness.
(bug 98707)
- Users can now change their email account.
(bug 23067)
- "Dependent Bug Changed" notification emails now contain the
dependent bug's summary and URL.
(bug 28736, 113383)
- Bugs with severity "critical", "blocker", and "enhancement" are
visually differentiated on bug lists for browsers with sufficient
CSS support.
(bug 28884)
- Bugzilla now has a sidebar for the Mozilla browser.
(bug 37339)
- A link to just created attachments now appears in notification
email.
(bug 66651)
- Comments now have numbers and can be referenced with
autohyperlinkifying similar to bugs.
(bug 71840)
- The attachment system has been rewritten, supporting new
"attachment statuses" (like keywords, but for attachments),
the ability to obsolete attachments, edit attachment MIME type,
and edit whether the attachment is a patch.
(bugs 84338, 75176)
- syncshadowdb now supports a configurable temp file location,
and properly shuts down Bugzilla while running.
(bug 75840)
- Dependency tree now lets you exclude resolved bugs and bugs
below a specified depth.
(bugs 83058)
- The "strictvaluechecks" parameter has gone away. These checks
are now always done.
(bug 119715)
- The midair collision page now shows all changes since the bug
page was loaded, not just the last one.
(bug 108312)
- Added support for making dependency graphs with 'dot', which
is better at creating complex graphs than 'webdot'.
(bug 120537)
*** Bug fixes of note ***
- Bugzilla scripts are now usually not terminated when the browser
window they are running in is closed. This caused hard to
reproduce bugs.
(bug 104589)
- On browsers that "reflow" the page, large component / milestone /
version fields were extremely slow to reflow when you altered
the product field.
(bug 96534)
- The selection in the component / milestone / version fields is
no longer lost when you change the selection in the product
field or use the back/forward buttons in your browser to return
to the page.
(bug 97966)
- You could not reverse dependencies in one step.
(bug 82143)
- Mass reassignment of non-open bugs will no longer reopen them.
(bug 30731)
- Attempting to bulk change no bugs will now give a user-friendly
error message.
(bug 90333)
- If you make a change to a bug where you only add yourself to CC,
email notifications are now properly sent out for MySQL 3.23.
(bug 99519)
- Bug entry now properly validates the data it has been sent.
(bug 107743)
- Midair collision checks will now properly work in all situations
where dependencies have changed.
(bug 73502)
- Browsers can no longer corrupt the params file if they use the "wrong"
end-of-line markers.
(bug 92500)
- The MySQL port defined in localconfig is now properly honoured.
(bug 98368)
- Apostrophes in component/milestone/version names no longer cause
a problem on the query page.
(bug 30689/42810)
- File attachment comments will now wrap.
(bug 52060)
- Saved queries are no longer mangled if you need to log in again,
for example if you had cookies off.
(bug 38835)
- Bug counts (on reports.cgi) were very slow if you had to
count a lot of bugs.
(bug 63249)
- 2.14 introduced options to let people see a bug when their name
is on it but who aren't in the groups the bug is restricted
to. These only allowed the people to view the bugs directly,
and not see them on buglists and receive email about them.
(bugs 95024, 97469)
- A new 'cookiepath' parameter on editparams.cgi allows multiple
Bugzilla installations to exist on one host without problems.
(bug 19910)
- whineatnews.pl now respects the 'sendmailnow' parameter.
(bug 52782)
- The query page came up even when Bugzilla was shut down.
(bug 121747)
- Quicksearch gave a weird error message when Bugzilla was
shut down.
(bug 121741)
- Operating system detection fixes.
(bugs 92763, 135666)
- QA contacts now receive emails when a new bug is created and
their only email preference was being added or removed from QA.
(bug 143091)

***********************************************
*** SECURITY ISSUES RESOLVED ***
- Basic maintenance on contrib/bug_email.pl and
contrib/bugzilla_email_append.pl which also fixes a
possible security hole with a misuse of a system() call.
These files are not supported at this time, but as long
as we knew about the problem, we couldn't overlook it.
(bug 154008)
*** Bug fixes of note ***
- The fix for bug 130821 in 2.14.2 broke being able to sort
bug lists on more than one field. buglist.cgi now allows
you to sort on more than one field again.
(bug 152138)
***********************************************
*** USERS UPGRADING FROM 2.14.1 OR EARLIER ***
***********************************************
*** SECURITY ISSUES RESOLVED ***
- queryhelp.cgi no longer shows confidential products to
people it shouldn't.
(bug 126801)
- It was possible for a user to bypass the IP check by
setting up a fake reverse DNS, if the Bugzilla web server
was configured to do reverse DNS lookups. Apache is not
configured as such by default. This is not a complete
exploit, as the user's login cookie would also need to
be divulged for this to be a problem.
(bug 129466)
- In some situations the data directory became world writeable.
(bug 134575)
- Any user with access to editusers.cgi could delete a user
regardless of whether 'allowuserdeletion' is on.
(bug 141557)
- Real names were not HTML filtered, causing possible cross
site scripting attacks.
(bug 146447, 147486)
- Mass change would set the groupset of every bug to be the
groupset of the first bug.
(bug 107718)
- Some browsers (eg NetPositive) interacted with Bugzilla
badly and could have various form problems, including
removing group restrictions on bugs.
(bug 148674)
- It was possible for random confidential information to be
divulged, if the shadow database was in use and became
corrupted.
(bug 92263)
- The bug list sort order is now stricter about the SQL it will accept,
ensuring you use correct column name syntax. Before this, there were
some syntax checks, so it is not known whether this problem was
exploitable.
(bug 130821)
Required Perl modules:
********************************************
*** USERS UPGRADING FROM 2.14 OR EARLIER ***
********************************************

The 2.14.1 release fixes several security issues that became
known to us after the Bugzilla 2.14 release.
*** SECURITY ISSUES RESOLVED ***
- If LDAP Authentication was being used, Bugzilla would allow
you to log in as anyone if you left the password blank.
(bug 54901)
- It was possible to add comments or file a bug as someone else
by editing the HTML on the appropriate submission page before
submitting the form. User identity is checked now, and the
form values suggesting the user are now ignored.
(bug 108385, 108516)
- The Product popup menu on the show_bug form listed all
products, even if the user didn't have access to all of them.
It now only shows products the user has access to (and the
product the bug is in, if the user is viewing it because of
some other override).
(bug 102141)
- If a user had any blessgroupset privileges (the ability to
change only specific privileges for other users), it was
possible to change your own groupset (privileges) by
altering the page HTML before submitting on editusers.cgi.
(bug 108821)
- An untrusted variable was echoed back to user in the HTML
output if there was a login error while editing votes.
(bug 98146)
- buglist.cgi had an undocumented parameter that allowed you
to pass arbitrary SQL for the "WHERE" part of a query.
This has been disabled.
(bug 108812)
- It was possible for a user to send arbitrary SQL by inserting
single quotes in the "mybugslink" field in the user
preferences.
(bug 108822)
- buglist.cgi was not validating that the field names being
passed from the "boolean chart" query form were valid field
names, thus allowing arbitrary SQL to be inserted if you
edited the HTML by hand before submitting the form.
(bug 109679)
- long_list.cgi was not validating that the bug ID parameter
was actually a number, allowing arbitrary SQL to be inserted
if you edited the HTML by hand.
(bug 109690)
Optional Perl modules:
********************************************
*** USERS UPGRADING FROM 2.12 OR EARLIER ***
********************************************
Chart::Base v1.0 (changed from 2.16) (changed from 2.17.7)
GD v1.20 (changed from 2.16)
GD::Graph (any) (new since 2.16)
GD::Text::Align (any) (new since 2.16)

*** SECURITY ISSUES RESOLVED ***
- Multiple instances of unauthorised access to confidential
bugs has been fixed.
(bug 39524, 39526, 39527, 39531, 39533, 70189, 82781)
- Multiple instances of untrusted parameters not being
checked/escaped was fixed. These included definite security
holes.
(bug 38854, 38855, 38859, 39536, 87701, 95235)
- After logging in passwords no longer appear in the URL.
(bug 15980)
- Procedures to prevent unauthorised access to confidential
files are now simpler. In particular the shadow directory
no longer exists and the data/comments file no longer needs
to be directly accessible, so the entire data directory can
be blocked. However, no changes are required here if you
have a properly secured 2.12 installation as no new files
must be protected.
(bug 71552, 73191)
- If they do not already exist, checksetup.pl will attempt to
write Apache .htaccess files by default, to prevent
unauthorised access to confidential files. You can turn this
off in the localconfig file.
(bug 76154)
- Sanity check can now only be run by people in the 'editbugs'
group. Although it would be better to have a separate
group, this is not possible until the limitation on the
number of groups allowed has been removed.
(bug 54556)
- The password is no longer stored in plaintext form. It will
be eradicated next time you run checksetup.pl. A user must
now change their password via a password change request that
gets validated at their e-mail account, rather than have it
mailed to them.
(bug 74032)
- When you are using product groups and you move a bug between
products (single or mass change), the bug will no longer be
restricted to the old product's group (if it was) and will
be restricted to the new product's group.
(bug 66235)
- There are now options on a bug to choose whether the
reporter, and CCs can access a bug even if they aren't in
groups the bug it is restricted to.
(bug 39816)
- You can no longer mark a bug as a duplicate of a bug you
can't see, and if you mark a bug a duplicate of a bug
the reporter cannot see you will be given options as to
what to do regarding adding the reporter of the resolved
bug to the CC of the open bug.
(bug 96085)
*** IMPORTANT CHANGES ***
- Bugzilla 2.14 no longer supports old email tech. Upon
upgrading, all users will be moved over to new email tech.
This should speed up upgrading for installations with
a large number of bugs.
(bug 71552)
- There is new functionality for people to see why they are
receiving notification mails.
Previously, some people filtered old email tech
notifications depending on whether they were in the To or the
CC header, in order to get a limited way of determining why
they were receiving the notification for filtering purposes.
Existing installations will need to make changes to support
this feature. The receive reasons can be added to the
notifications as a header and/or in the body. To add these
you will need to modify your newchangedmail parameter on
editparams.cgi, either by resetting it or appropriately
modifying it. The header value is specified by
%reasonsheader% and the body by %reasonsbody%. For example,
the new default parameter is:
--------------------------------------------------
From: bugzilla-daemon
To: %to%
Subject: [Bug %bugid%] %neworchanged%%summary%
X-Bugzilla-Reason: %reasonsheader%
%urlbase%show_bug.cgi?id=%bugid%
%diffs%
%reasonsbody%
--------------------------------------------------
(bug 26194)
- Very long fields (especially multi-valued fields like keywords,
CCs, dependencies) on bug activity and notifications previously
could get truncated, resulting in useless notifications and data
loss on bug activity. Now the multi-valued fields only show
changes, and very big changes are split into multiple lines.
Where data loss has already occurred on bug activity, it is
indicated using question marks.
(bug 55161, 92266)
- Previously, when a product's voting preferences changed all
votes were removed from all the bugs in the product. Also,
when a bug was moved to another product, all of its votes
were removed. This no longer occurs.
Instead, if the action would leave one or more bugs with
greater than the maximum number of votes per person per bug,
the number of votes will be reduced to the maximum. The
person will still be notified of this as before.
If the action would leave a user with more votes in a product
than is allowed, the limit will be breached so as to not lose
votes. However the user will not be able to update their
votes except to fix this situation. No further action is taken
in this version to make sure that the user does this.
(bug 28882, 92593)
*** Other changes of note ***
- Groups can now be marked inactive, so you can't add a new
restriction on that group to a bug, while leaving bugs that
were previously restricted on that group alone.
(bug 75482)
- backdoor.cgi has been removed from the installation. It was
old code that was Netscape-specific and its name was scaring
people.
(bug 87983)
- You can now add or remove from CC on the bulk change page.
(bug 12819)
- New users created by administrators are now automatically
inserted into groups according to the group's regular
expression. Administrators must edit the user in a second
step to override these choices. Previously the
administrator specified these explicitly which could lead
to incorrect settings.
(bug 45164)
- The userregexp of system groups can now be edited without
resorting to direct database access.
(bug 65290)
*** Bug fixes of note ***
- The bug list page was sometimes bringing up a not logged in
footer when the user was logged in and the installation was
using a shadow database.
(bug 47914)
- You can now view the bug summary in your browser title for
a group-restricted bug if you have proper permissions.
(bug 71767)
- Quick search for search terms did not work in IE5.
This has been worked around.
(bug 77699)
- Quick search for search terms crashed NN4.76/4.77 for Unix.
This has been worked around.
(bug 83619)
- Queries on bugs you have commented on using the "added
comment" feature should be a lot faster and not time out
on large installations due to the addition of an index.
(bug 57350)
- You can now alter group settings on bulk change for groups
that aren't on for all bugs or off for all bugs.
(bug 84714)
- New bug notifications now include the CC and QA fields.
(bug 28458)
- Bugzilla is now more Windows friendly, although it is still
not an official platform.
(bug 88179, 29064)
- Passwords are now encrypted using Perl's encrypt function.
This makes Bugzilla more portable to more operating systems.
(bug 77473)
- Bugzilla didn't properly shut down when told to - some
queries could still be sent to the database.
(bug 95082)
What's New?
***********
Generic Reporting
-----------------
Bugzilla has a new mechanism for generating reports of the current state of
the bug database. It has two related parts: a table-based view, and several
graphical views.
The table-based view allows you to specify an x, y and z (multiple tables of
data) axis to plot, and then restrict the bugs plotted using the standard
query form. You can view the resulting data as an HTML or CSV export (e.g.:
for importing into a spreadsheet).
There are also bar, line and pie charts, which are defined in a very similar
way. These views may be more appropriate for particular data types, and are
suitable for saving and then putting into presentations or web pages.
Request System
---------------
The Request System (RS) is a set of enhancements that adds powerful flag
(superset of the old attachment status) features to the bugs.
RS allows for four states: off, granted, denied, and (optionally) requested,
where "granted" is the equivalent of "on". These additions mean it is no
longer necessary to define a status to negate another status (e.g.
"needs-work" to negate "has-review") because negation is built into each
status via the status' "denied" state. Bug statuses: Previously only
attachments could have these kinds of statuses. RS enables them for bugs as
well. This feature can be used to request and grant/deny certain properties
for a bug, such as inclusion for a specific milestone or approval for checkin.
This way, Bugzilla supports the natural decision-making process in your
organization.
- Requests: Flags can now optionally be made requestable, which means users
can ask other users to set them. When a user requests a flag, Bugzilla
emails the requestee and adds the request to a browsable queue so both the
requester and the requestee can keep track of its status. Once the
requestee fulfills the request by setting the flag to either granted or
denied, Bugzilla emails the requestee and removes the request from the
queue. This feature supports workflow like the mozilla.org code review
and milestone approval processes, whereby code is peer reviewed before
being committed and patches get approved by product release managers for
inclusion in specific product releases.
- Product/component specificity: Previously flags were product-specific, and
if you wanted the same flag for multiple products you had to define
multiple flags with the same name. Flags are now
product/component-specific, and a single flag can be enabled or disabled
for multiple product/component combinations via inclusions and exclusions
lists. Flags are enabled for all combinations on their inclusions list
except those that appear on their exclusions list.
Enterprise Group Support
------------------------
Bugzilla is no longer limited to 55 access control groups. Administrators can
define an arbitrary number of access groups composed of individual users or
other groups. The groups can be configured via the web interface to achieve a
wide variety of access control policies. See the documentation section on
'Groups And Group Controls' for details.
User Wildcard Matching
----------------------
Sites can now enable the use of wildcards and substrings in bug entry and
editing forms. If the user enters an incomplete username, he'll get a list of
users that matched the given username.
Support for "Insiders"
----------------------
If the 'insidergroup' parameter is defined, a specific group of users can be
designated insiders who can designate comments and attachments as private to
other insiders. These comments and attachments will be invisible to other
users who are not members of the insiders group even if the bugs to which they
apply are visible. Other insiders will see the comments and attachments with a
visual tinting indicating that they are private.
Time Tracking
-------------
Controls for tracking time spent fixing bugs are included in the bug form for
members of the group specified by the 'timetrackinggroup' parameter. Any time
comments are added to the bug, members of the time tracking group can add an
amount of time they spent, and it's figured into the total and displayed at
the top of the bug. Shown in the bug are your original estimate, the amount of
time spent so far, the revised estimate of how much time is remaining, and
your gain/loss on the original estimate.
Authentication module/LDAP improvements
---------------------------------------
Bugzilla's authentication mechanisms have been modularized, making pluggable
authentication schemes for Bugzilla a reality. Both the existing database and
LDAP systems were ported as part of modularization process. Additionally, the
CGI portion of the backend was redesigned to allow for authentication from
other sources, including (theoretically) email, which will help Bug 94850.
As part of this conversion, LDAP logins now use Perl's standard Net::LDAP
module, which has no external library dependencies.
Improved localization support
-----------------------------
Bugzilla administrators can now configure which languages are supported by
their installations and automatically serve correct, localized content to
users based on the HTTP 'Accept-Language' header sent from users' browsers.
There are currently localized templates available for: Arabic, Belarusian,
Chinese, French, German, Italian, Korean, Portuguese (Brazil) Spanish (Spain
or Mexico) and Russian. These localized template packs are third-party
contributions, may only be available for specific versions, and may not be
supported in the future. (http://www.bugzilla.org/download/#localizations)
Patch Viewer
------------
Viewing and reviewing patches in Bugzilla is often difficult due to lack of
context, improper format and the inherent readability issues that raw patches
present. Patch Viewer is an enhancement to Bugzilla designed to fix that by
offering increased context, linking to sections, and integrating with Bonsai,
LXR and CVS.
Comment Reply Links
-------------------
In Edit Bug, each bug comment now includes a convenient (reply) link that
quotes the comment text into the textarea. This feature is only enabled in
Javascript-capable browsers, but causes no inconvenience to other user agents.
Full-Text Search
----------------
It is now possible to query the Bugzilla database using full-text searching,
which spans comments and summaries, and which searches for substrings and stem
variations of the search term. Basically, it's like using Google.
Email Address Munging
---------------------
The fact that raw email addresses are displayed in Bugzilla makes it trivial
for bots that spamharvest to spider through Bugzilla, in particular, through
Bugzilla's buglists. This change adds HTML obfuscation of email addresses as
they appear in the Bugzilla web pages.
Generic Charting
----------------
Bugzilla's new charting feature allows you to display flexible summary charts,
based on configurable data sets (bug 16009).
Miscellaneous Improvements
--------------------------
- The "Assigned To" field on the new bug page is now prefilled with the default
component owner.
- A bug alias column is now available in the buglist page.
- Lists of bugs containing errors in the sanity check page now have a "view as
buglist" link in addition to the individual bug links.
- Autolinkification Page - It's now possible to apply Bugzilla's comment
hyperlinking algorithm to any text you like. This should be useful for status
updates and other web pages which give lists of bugs. The bug links created
include the subject, status and resolution of the bug as a tooltip.
- There are more <link> tags on the links toolbar for navigating quickly between
different areas.
- Buglists are now available as comma-separated value files (CSV) and JavaScript
(JS) as well as HTML and RDF.
- Keywords and dependencies can now be entered during initial bug entry.
- A CSS id signature unique to each Bugzilla installation is now added to the
<body> tag on Bugzilla pages to allow custom end-user CSS to explicitly affect
Bugzilla.
- Perl's path has been changed to a normal /usr/bin/perl from the original
legacy "bonsaitools" path specifier.
- A new "always-require-login" parameter allows administrators to require a
login before being able to view any page, except the front page.
- A developer may add an attachment, and also reassign a bug to himself as part
of that single action.
- Bugzilla is now able to use the replication facilities provided by the
MySQL database to handle updates from the main database to the secondaries.
- Mail handling is now between 125% to 175% faster.
Code Changes Which May Affect Customizations
********************************************
*** USERS UPGRADING FROM 2.10 OR EARLIER ***
********************************************
*** SECURITY ISSUES RESOLVED ***
- Some security holes have been fixed where shell escape characters
could be passed to Bugzilla, allowing remote users to execute
system commands on the web server.
*** IMPORTANT CHANGES ***
- There is now a facility for users to choose the sort of
notifications they wish to receive. This facility will
probably be improved in future versions.
(bug 17464)
- "Changed" will no longer appear on the subject line of
change notification emails. Because of this, you should
change the subject line in your 'changedmail' and
'newchangedmail' params on editparams.cgi. The subject
line needs to be changed from
Subject: [Bug %bugid%] %neworchanged% - %summary%
to:
Subject: [Bug %bugid%] %neworchanged%%summary%
or whatever is appropriate for the subject you are using
on your system. Note the removal of the " - " in the
middle.
(bug 29820)
*** Other changes of note ***
- Bug titles now appear in the page title, and will hence
display in the user's browser's bookmarks and history.
(bug 22041)
- Edit groups functionality (editgroups.cgi).
(bug 25010)
- Support for moving bugs to other Bugzilla databases.
(bug 36133)
- Bugzilla now can generate a frequently reported bugs list
based on what duplicates you receive.
(bug 25693)
- When installing Bugzilla fresh, the administrator account is
now created in checksetup.pl.
(bug 17773)
- Stored queries now show their name above the bug list, which
helps the user when they have multiple bug lists in multiple
browser windows. It also appears in the page title, and will
hence display in the user's browser's bookmarks and history.
(bug 52228)
- All states and resolutions can now be collected for charting.
(bug 6682)
- A new search-engine-like "quick search" feature appears on
the front page to try and making searching easier.
(bug 69793)
- Querying on dependencies now works in the advanced query
section of the query page.
(bug 30823)
- When a bug is marked as a duplicate, the reporter of the
resolved bug is automatically added to the CC list of the
open bug.
(bug 28676)
*** Bug fixes of note ***
- Notification emails will now always be sent to QA contacts.
Previously they wouldn't if you were using new email tech.
(bug 30826)
- When marking a bug as a duplicate, the duplicate stamp marked
on the open bug will no longer be written too early (such as
on mid-air collisions).
(bug 7873)
- Various bug fixes were made to the initial assignee and QA
of a component. It is no longer possible to enter an
invalid address. They will also now properly update when
a user's email address is changed. Sanity check will now
check these.
(bug 66876)
- Administrators can no longer create an email accounts that do
not match the global email regular expression parameter.
Previously this could occur and would cause sanity check
errors.
(bug 32971)
- The resolution field can no longer become empty when the
bug is resolved. This occurred because of midair collisions.
(bug 49306)
*******************************************
*** USERS UPGRADING FROM 2.8 OR EARLIER ***
*******************************************
Release notes were not compiled for versions of Bugzilla before
2.12.
The file 'UPGRADING-pre-2.8' contains instructions you may
need to perform in addition to running 'checksetup.pl' if you
are running a pre 2.8 version.
- A mechanism (called "Template Hooks") for third party extensions to plug into
existing templates without having to patch or replace distributed templates
has been added. More information on this can be found in the documentation.
- Header output now uses CGI.pm, in a step towards enabling mod_perl
compatibility. This change will affect users that had customized charsets in
their CGI files: previously the charset had to be added everywhere that
printed the Content-Type header; now it only needs changing in one spot, in
Bugzilla/CGI.pm.
- $::FORM{} and $::COOKIE{} are deprecated. Use the $cgi methods to access
them.
- $::userid is gone in favor of Bugzilla->user->id
- ConnectToDatabase() is gone (it's done automatically when you initialize the
Bugzilla object)
- quietly_check_login() and confirm_login() are gone, use Bugzilla->login()
with parameters for whether the login is required or not.
- Use Bugzilla->user->login in place of $::COOKIE{Bugzilla_login}
- You can tell if there's a user logged in or not by checking if
Bugzilla->user exists rather than looking for $::userid==0
Recommended Practice for the Upgrade
************************************
As always, please ensure you have run checksetup.pl after replacing the
files in your installation.
It is recommended that you view the sanity check page (sanitycheck.cgi) both
before the upgrade and after running checksetup.pl after the upgrade, to see
if there are any problems with your installation.
It is also recommended that, if possible, you fix any problems you find
immediately. Failure to do this may mean that Bugzilla will not work correctly.
Be aware that if the sanity check page contains more errors after an upgrade,
it doesn't necessarily mean there are more errors in your database, as
additional tests are added to the sanity check over time, and it is possible
that those errors weren't being checked for in the old version.
As previously noted in the Dependency Requirements MySQL is now required to be
at least version 3.23.41. This implies that all tables of type ISAM will be
converted by the checksetup.pl script to MyISAM. As with any upgrade it is
recommended to make a backup of the database, perhaps by using mysqldump.
Example:
mysqldump -u root -p --databases bugs > bugs.db.backup
