The&nbsp;following&nbsp;is&nbsp;a&nbsp;guide&nbsp;for&nbsp;reviewers&nbsp;when&nbsp;checking&nbsp;code&nbsp;into&nbsp;Bugzilla's<br>
CVS&nbsp;repostory&nbsp;at&nbsp;mozilla.org.&nbsp;&nbsp;If&nbsp;you&nbsp;wish&nbsp;to&nbsp;submit&nbsp;patches&nbsp;to&nbsp;Bugzilla,<br>
you&nbsp;should&nbsp;follow&nbsp;the&nbsp;rules&nbsp;and&nbsp;style&nbsp;conventions&nbsp;below.&nbsp;&nbsp;Any&nbsp;code&nbsp;that<br>
does&nbsp;not&nbsp;adhere&nbsp;to&nbsp;these&nbsp;basic&nbsp;rules&nbsp;will&nbsp;not&nbsp;be&nbsp;added&nbsp;to&nbsp;Bugzilla's<br>
codebase.<br>
<br>
&nbsp;1.&nbsp;Usage&nbsp;of&nbsp;variables&nbsp;in&nbsp;Regular&nbsp;Expressions<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;It&nbsp;is&nbsp;very&nbsp;important&nbsp;that&nbsp;you&nbsp;don't&nbsp;use&nbsp;a&nbsp;variable&nbsp;in&nbsp;a&nbsp;regular<br>
&nbsp;&nbsp;&nbsp;&nbsp;expression&nbsp;unless&nbsp;that&nbsp;variable&nbsp;is&nbsp;supposed&nbsp;to&nbsp;contain&nbsp;an&nbsp;expression.<br>
&nbsp;&nbsp;&nbsp;&nbsp;This&nbsp;especially&nbsp;applies&nbsp;when&nbsp;using&nbsp;grep.&nbsp;&nbsp;You&nbsp;should&nbsp;use:<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;grep&nbsp;($_&nbsp;eq&nbsp;$value,&nbsp;@array);<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;-&nbsp;NOT&nbsp;-<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;grep&nbsp;(/$value/,&nbsp;@array);<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;If&nbsp;you&nbsp;need&nbsp;to&nbsp;use&nbsp;a&nbsp;non-expression&nbsp;variable&nbsp;inside&nbsp;of&nbsp;an&nbsp;expression,&nbsp;be<br>
&nbsp;&nbsp;&nbsp;&nbsp;sure&nbsp;to&nbsp;quote&nbsp;it&nbsp;properly&nbsp;(using&nbsp;\Q..\E).<br>
<br>
Coding&nbsp;Style&nbsp;for&nbsp;Bugzilla<br>
-------------------------<br>
<br>
While&nbsp;it's&nbsp;true&nbsp;that&nbsp;not&nbsp;all&nbsp;of&nbsp;the&nbsp;code&nbsp;currently&nbsp;in&nbsp;Bugzilla&nbsp;adheres&nbsp;to<br>
this&nbsp;styleguide,&nbsp;it&nbsp;is&nbsp;something&nbsp;that&nbsp;is&nbsp;being&nbsp;worked&nbsp;toward.&nbsp;&nbsp;Therefore,<br>
we&nbsp;ask&nbsp;that&nbsp;all&nbsp;new&nbsp;code&nbsp;(submitted&nbsp;patches&nbsp;and&nbsp;new&nbsp;files)&nbsp;follow&nbsp;this&nbsp;guide<br>
as&nbsp;closely&nbsp;as&nbsp;possible&nbsp;(if&nbsp;you're&nbsp;only&nbsp;changing&nbsp;1&nbsp;or&nbsp;2&nbsp;lines,&nbsp;you&nbsp;don't&nbsp;have<br>
to&nbsp;reformat&nbsp;the&nbsp;entire&nbsp;file&nbsp;:).<br>
<br>
&nbsp;1.&nbsp;Whitespace<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;Bugzilla's&nbsp;prefered&nbsp;indentation&nbsp;is&nbsp;4&nbsp;spaces&nbsp;(no&nbsp;tabs,&nbsp;please).<br>
<br>
&nbsp;2.&nbsp;Curly&nbsp;braces.<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;The&nbsp;opening&nbsp;brace&nbsp;of&nbsp;a&nbsp;block&nbsp;should&nbsp;be&nbsp;on&nbsp;the&nbsp;same&nbsp;line&nbsp;as&nbsp;the&nbsp;statement<br>
&nbsp;&nbsp;&nbsp;&nbsp;that&nbsp;is&nbsp;causing&nbsp;the&nbsp;block&nbsp;and&nbsp;the&nbsp;closing&nbsp;brace&nbsp;should&nbsp;be&nbsp;at&nbsp;the&nbsp;same<br>
&nbsp;&nbsp;&nbsp;&nbsp;indentation&nbsp;level&nbsp;as&nbsp;that&nbsp;statement,&nbsp;for&nbsp;example:<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;if&nbsp;($var)&nbsp;{<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print&nbsp;"The&nbsp;variable&nbsp;is&nbsp;true";<br>
&nbsp;&nbsp;&nbsp;&nbsp;}<br>
&nbsp;&nbsp;&nbsp;&nbsp;else&nbsp;{<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print&nbsp;"Try&nbsp;again";<br>
&nbsp;&nbsp;&nbsp;&nbsp;}<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;-&nbsp;NOT&nbsp;-<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;if&nbsp;($var)<br>
&nbsp;&nbsp;&nbsp;&nbsp;{<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print&nbsp;"The&nbsp;variable&nbsp;is&nbsp;true";<br>
&nbsp;&nbsp;&nbsp;&nbsp;}<br>
&nbsp;&nbsp;&nbsp;&nbsp;else<br>
&nbsp;&nbsp;&nbsp;&nbsp;{<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print&nbsp;"Try&nbsp;again";<br>
&nbsp;&nbsp;&nbsp;&nbsp;}<br>
<br>
&nbsp;3.&nbsp;File&nbsp;Names<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;File&nbsp;names&nbsp;for&nbsp;bugzilla&nbsp;code&nbsp;and&nbsp;support&nbsp;documention&nbsp;should&nbsp;be&nbsp;legal&nbsp;across<br>
&nbsp;&nbsp;&nbsp;&nbsp;multiple&nbsp;platforms.&nbsp;&nbsp;\&nbsp;/&nbsp;:&nbsp;*&nbsp;?&nbsp;"&nbsp;&#60;&nbsp;&#62;&nbsp;and&nbsp;|&nbsp;are&nbsp;all&nbsp;illegal&nbsp;characters&nbsp;for<br>
&nbsp;&nbsp;&nbsp;&nbsp;filenames&nbsp;on&nbsp;various&nbsp;platforms.&nbsp;&nbsp;Also,&nbsp;file&nbsp;names&nbsp;should&nbsp;not&nbsp;have&nbsp;spaces&nbsp;in<br>
&nbsp;&nbsp;&nbsp;&nbsp;them&nbsp;as&nbsp;they&nbsp;can&nbsp;cause&nbsp;confusion&nbsp;in&nbsp;CVS&nbsp;and&nbsp;other&nbsp;mozilla.org&nbsp;utilities.<br>
<br>
&nbsp;4.&nbsp;Variable&nbsp;Names<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;If&nbsp;a&nbsp;variable&nbsp;is&nbsp;scoped&nbsp;globally&nbsp;($::variable)&nbsp;its&nbsp;name&nbsp;should&nbsp;be&nbsp;descriptive<br>
&nbsp;&nbsp;&nbsp;&nbsp;of&nbsp;what&nbsp;it&nbsp;contains.&nbsp;&nbsp;Local&nbsp;variables&nbsp;can&nbsp;be&nbsp;named&nbsp;a&nbsp;bit&nbsp;looser,&nbsp;provided&nbsp;the<br>
&nbsp;&nbsp;&nbsp;&nbsp;context&nbsp;makes&nbsp;their&nbsp;content&nbsp;obvious.&nbsp;&nbsp;For&nbsp;example,&nbsp;$ret&nbsp;could&nbsp;be&nbsp;used&nbsp;as&nbsp;a<br>
&nbsp;&nbsp;&nbsp;&nbsp;staging&nbsp;variable&nbsp;for&nbsp;a&nbsp;routine's&nbsp;return&nbsp;value&nbsp;as&nbsp;the&nbsp;line&nbsp;|return&nbsp;$ret;|&nbsp;will<br>
&nbsp;&nbsp;&nbsp;&nbsp;make&nbsp;it&nbsp;blatently&nbsp;obvious&nbsp;what&nbsp;the&nbsp;variable&nbsp;holds&nbsp;and&nbsp;most&nbsp;likely&nbsp;be&nbsp;shown<br>
&nbsp;&nbsp;&nbsp;&nbsp;on&nbsp;the&nbsp;same&nbsp;screen&nbsp;as&nbsp;|my&nbsp;$ret&nbsp;=&nbsp;"";|.<br>
<br>
&nbsp;5.&nbsp;Cross&nbsp;Database&nbsp;Compatability<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;Bugzilla&nbsp;was&nbsp;originally&nbsp;written&nbsp;to&nbsp;work&nbsp;with&nbsp;MySQL&nbsp;and&nbsp;therefore&nbsp;took&nbsp;advantage<br>
&nbsp;&nbsp;&nbsp;&nbsp;of&nbsp;some&nbsp;of&nbsp;its&nbsp;features&nbsp;that&nbsp;aren't&nbsp;contained&nbsp;in&nbsp;other&nbsp;RDBMS&nbsp;software.&nbsp;&nbsp;These<br>
&nbsp;&nbsp;&nbsp;&nbsp;should&nbsp;be&nbsp;avoided&nbsp;in&nbsp;all&nbsp;new&nbsp;code.&nbsp;&nbsp;Examples&nbsp;of&nbsp;these&nbsp;features&nbsp;are&nbsp;enums&nbsp;and<br>
&nbsp;&nbsp;&nbsp;&nbsp;encrypt().<br>
<br>
&nbsp;6.&nbsp;Cross&nbsp;Platform&nbsp;Compatability<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;While&nbsp;Bugzilla&nbsp;was&nbsp;written&nbsp;to&nbsp;be&nbsp;used&nbsp;on&nbsp;Unix&nbsp;based&nbsp;systems&nbsp;(and&nbsp;Unix/Linux&nbsp;is<br>
&nbsp;&nbsp;&nbsp;&nbsp;still&nbsp;the&nbsp;only&nbsp;officially&nbsp;supported&nbsp;platform)&nbsp;there&nbsp;are&nbsp;many&nbsp;who&nbsp;desire/need&nbsp;to<br>
&nbsp;&nbsp;&nbsp;&nbsp;run&nbsp;Bugzilla&nbsp;on&nbsp;Microsoft&nbsp;Windows&nbsp;boxes.&nbsp;&nbsp;Whenever&nbsp;possible,&nbsp;we&nbsp;should&nbsp;strive<br>
&nbsp;&nbsp;&nbsp;&nbsp;not&nbsp;to&nbsp;make&nbsp;the&nbsp;lives&nbsp;of&nbsp;these&nbsp;people&nbsp;any&nbsp;more&nbsp;complicated&nbsp;and&nbsp;avoid&nbsp;doing&nbsp;things<br>
&nbsp;&nbsp;&nbsp;&nbsp;that&nbsp;break&nbsp;Bugzilla's&nbsp;ability&nbsp;to&nbsp;run&nbsp;on&nbsp;multiple&nbsp;operating&nbsp;systems.<br>

routine's return value as the line <TT

&nbsp;&nbsp;&nbsp;&nbsp;Bugzilla&nbsp;was&nbsp;originally&nbsp;written&nbsp;to&nbsp;work&nbsp;with&nbsp;MySQL&nbsp;and&nbsp;therefore&nbsp;took&nbsp;advantage<br>
&nbsp;&nbsp;&nbsp;&nbsp;of&nbsp;some&nbsp;of&nbsp;its&nbsp;features&nbsp;that&nbsp;aren't&nbsp;contained&nbsp;in&nbsp;other&nbsp;RDBMS&nbsp;software.&nbsp;&nbsp;These<br>
&nbsp;&nbsp;&nbsp;&nbsp;should&nbsp;be&nbsp;avoided&nbsp;in&nbsp;all&nbsp;new&nbsp;code.&nbsp;&nbsp;Examples&nbsp;of&nbsp;these&nbsp;features&nbsp;are&nbsp;enums&nbsp;and<br>

<br>
&nbsp;&nbsp;&nbsp;&nbsp;While&nbsp;Bugzilla&nbsp;was&nbsp;written&nbsp;to&nbsp;be&nbsp;used&nbsp;on&nbsp;Unix&nbsp;based&nbsp;systems&nbsp;(and&nbsp;Unix/Linux&nbsp;is<br>
&nbsp;&nbsp;&nbsp;&nbsp;still&nbsp;the&nbsp;only&nbsp;officially&nbsp;supported&nbsp;platform)&nbsp;there&nbsp;are&nbsp;many&nbsp;who&nbsp;desire/need&nbsp;to<br>

<title>Hacking Bugzilla</title>
<para>
What follows are some general guidelines for changing Bugzilla, and adhering to good coding practice while doing so. We've had some checkins in the past which ruined Bugzilla installations because of disregard for these conventions. Sorry for the lack of formatting; I got this info into the Guide on the day of 2.14 release and haven't formatted it yet.
The following is a guide for reviewers when checking code into Bugzilla's
CVS repostory at mozilla.org. If you wish to submit patches to Bugzilla,
you should follow the rules and style conventions below. Any code that
does not adhere to these basic rules will not be added to Bugzilla's
codebase.
</para>
<literallayout>
The following is a guide for reviewers when checking code into Bugzilla's
CVS repostory at mozilla.org. If you wish to submit patches to Bugzilla,
you should follow the rules and style conventions below. Any code that
does not adhere to these basic rules will not be added to Bugzilla's
codebase.
1. Usage of variables in Regular Expressions
It is very important that you don't use a variable in a regular
expression unless that variable is supposed to contain an expression.
This especially applies when using grep. You should use:
grep ($_ eq $value, @array);
- NOT -
grep (/$value/, @array);
If you need to use a non-expression variable inside of an expression, be
sure to quote it properly (using \Q..\E).
Coding Style for Bugzilla
-------------------------
While it's true that not all of the code currently in Bugzilla adheres to
this styleguide, it is something that is being worked toward. Therefore,
we ask that all new code (submitted patches and new files) follow this guide
as closely as possible (if you're only changing 1 or 2 lines, you don't have
to reformat the entire file :).
1. Whitespace
Bugzilla's prefered indentation is 4 spaces (no tabs, please).
2. Curly braces.
The opening brace of a block should be on the same line as the statement
that is causing the block and the closing brace should be at the same
indentation level as that statement, for example:
if ($var) {
print "The variable is true";
}
else {
print "Try again";
}
- NOT -
if ($var)
{
print "The variable is true";
}
else
{
print "Try again";
}
3. File Names
File names for bugzilla code and support documention should be legal across
multiple platforms. \ / : * ? " < > and | are all illegal characters for
filenames on various platforms. Also, file names should not have spaces in
them as they can cause confusion in CVS and other mozilla.org utilities.
4. Variable Names
If a variable is scoped globally ($::variable) its name should be descriptive
of what it contains. Local variables can be named a bit looser, provided the
context makes their content obvious. For example, $ret could be used as a
staging variable for a routine's return value as the line |return $ret;| will
make it blatently obvious what the variable holds and most likely be shown
on the same screen as |my $ret = "";|.
5. Cross Database Compatability
Bugzilla was originally written to work with MySQL and therefore took advantage
of some of its features that aren't contained in other RDBMS software. These
should be avoided in all new code. Examples of these features are enums and
encrypt().
6. Cross Platform Compatability
While Bugzilla was written to be used on Unix based systems (and Unix/Linux is
still the only officially supported platform) there are many who desire/need to
run Bugzilla on Microsoft Windows boxes. Whenever possible, we should strive
not to make the lives of these people any more complicated and avoid doing things
that break Bugzilla's ability to run on multiple operating systems.

checkins in the past which ruined Bugzilla installations because of
disregard for these conventions. Sorry for the lack of formatting; I
got this info into the Guide on the day of 2.14 release and haven't

The following is a guide for reviewers when checking code into
Bugzilla's CVS repostory at mozilla.org. If you wish to submit patches
to Bugzilla, you should follow the rules and style conventions below.
Any code that does not adhere to these basic rules will not be added

you should follow the rules and style conventions below. Any code tha
t
does not adhere to these basic rules will not be added to Bugzilla's
codebase.
1. Usage of variables in Regular Expressions
It is very important that you don't use a variable in a regular
expression unless that variable is supposed to contain an expressi
on.
This especially applies when using grep. You should use:
grep ($_ eq $value, @array);
- NOT -
grep (/$value/, @array);
If you need to use a non-expression variable inside of an expressi
on, be
sure to quote it properly (using \Q..\E).

-- NOT THIS --
grep (/$value/, @array);
Note
If you need to use a non-expression variable inside of an expression,
be sure to quote it properly (using \Q..\E).
_________________________________________________________________
D.5.2. Coding Style for Bugzilla
While it's true that not all of the code currently in Bugzilla adheres
to
this styleguide, it is something that is being worked toward. Therefo
re,
we ask that all new code (submitted patches and new files) follow this
guide
as closely as possible (if you're only changing 1 or 2 lines, you don'
t have
to reformat the entire file :).
1. Whitespace
to this (or any) styleguide, it is something that is being worked
toward. Therefore, we ask that all new code (submitted patches and new
files) follow this guide as closely as possible (if you're only
changing 1 or 2 lines, you don't have to reformat the entire file :).
The Bugzilla development team has decided to adopt the perl style
guide as published by Larry Wall. This giude can be found in
"Programming Perl" (the camel book) or by typing man perlstyle at your
favorite shell prompt.
What appears below if a brief summary, please refer to the perl style
guide if you don't see your question covered here.
* Whitespace
Bugzilla's prefered indentation is 4 spaces (no tabs, please).
2. Curly braces.
The opening brace of a block should be on the same line as the sta
tement
that is causing the block and the closing brace should be at the s
ame
indentation level as that statement, for example:
if ($var) {
print "The variable is true";
}
else {
print "Try again";
}
- NOT -
if ($var)
{
print "The variable is true";
}
else
{
print "Try again";
}
3. File Names
File names for bugzilla code and support documention should be leg
al across
multiple platforms. \ / : * ? " < > and | are all illegal charact
ers for
filenames on various platforms. Also, file names should not have
spaces in
them as they can cause confusion in CVS and other mozilla.org util
ities.
4. Variable Names
* Curly braces.
The opening brace of a block should be on the same line as the
statement that is causing the block and the closing brace should
be at the same indentation level as that statement, for example:
if ($var) {
print "The variable is true";
}
else {
print "Try again";
}
-- NOT THIS --
if ($var)
{
print "The variable is true";
}
else
{
print "Try again";
}
* File Names
File names for bugzilla code and support documention should be
legal across multiple platforms. \ / : * ? " < > and | are all
illegal characters for filenames on various platforms. Also, file
names should not have spaces in them as they can cause confusion
in CVS and other mozilla.org utilities.
* Variable Names
If a variable is scoped globally ($::variable) its name should be
descriptive
of what it contains. Local variables can be named a bit looser, p
rovided the
context makes their content obvious. For example, $ret could be u
sed as a
staging variable for a routine's return value as the line |return
$ret;| will
make it blatently obvious what the variable holds and most likely
be shown
on the same screen as |my $ret = "";|.
5. Cross Database Compatability
Bugzilla was originally written to work with MySQL and therefore t
ook advantage
of some of its features that aren't contained in other RDBMS softw
are. These
should be avoided in all new code. Examples of these features are
enums and
encrypt().
6. Cross Platform Compatability
While Bugzilla was written to be used on Unix based systems (and U
nix/Linux is
still the only officially supported platform) there are many who d
esire/need to
run Bugzilla on Microsoft Windows boxes. Whenever possible, we sh
ould strive
not to make the lives of these people any more complicated and avo
