Coding Style for Bugzilla</H2 -><P -> While it's true that not all of the code currently in Bugzilla adheres 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 :). - </P -><P -> The Bugzilla development team has decided to adopt the perl style guide as - published by Larry Wall. This giude can be found in <SPAN -CLASS="QUOTE" ->"Programming - Perl"</SPAN -> (the camel book) or by typing <B -CLASS="command" ->man perlstyle</B -> at - your favorite shell prompt. - </P -><P -> What appears below if a brief summary, please refer to the perl style - guide if you don't see your question covered here. It is much better to submit - a patch which fails these criteria than no patch at all, but please try to meet - these minimum standards when submitting code to Bugzilla. - </P -><P -></P -><UL -><LI -><P -> Whitespace - </P -><P -> Bugzilla's preferred indentation is 4 spaces (no tabs, please). - </P -></LI -><LI -><P -> Curly braces. - </P -><P -> 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: - </P -><P -> <TABLE -BORDER="0" -BGCOLOR="#E0E0E0" -WIDTH="100%" -><TR -><TD -><FONT -COLOR="#000000" -><PRE -CLASS="programlisting" -> if ($var) { - print "The variable is true"; -} -else { - print "Try again"; -} - </PRE -></FONT -></TD -></TR -></TABLE -> - </P -><P -> -- NOT THIS -- - </P -><P -> <TABLE -BORDER="0" -BGCOLOR="#E0E0E0" -WIDTH="100%" -><TR -><TD -><FONT -COLOR="#000000" -><PRE -CLASS="programlisting" -> if ($var) -{ - print "The variable is true"; -} -else -{ - print "Try again"; -} - </PRE -></FONT -></TD -></TR -></TABLE -> - </P -></LI -><LI -><P -> Cookies - </P -><P -> Bugzilla uses cookies to ease the user experience, but no new patches - should <EM ->require</EM -> user-side cookies. - </P -></LI -><LI -><P -> File Names - </P -><P -> File names for bugzilla code and support documention should be legal across - multiple platforms. <TT -CLASS="computeroutput" ->\ / : * ? " < ></TT -> - and <TT -CLASS="computeroutput" ->|</TT -> 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. - </P -></LI -><LI -><P -> Javascript dependencies - </P -><P -> While Bugzilla uses Javascript to make the user experience easier, no patch - to Bugzilla should <EM ->require</EM -> Javascript. - </P -></LI -><LI -><P -> Patch Format - </P -><P -> All patches submitted for inclusion into Bugzilla should be in the form of a - <SPAN -CLASS="QUOTE" ->"unified diff"</SPAN ->. This comes from using <SPAN -CLASS="QUOTE" ->"diff -u"</SPAN -> - instead of simply <SPAN -CLASS="QUOTE" ->"diff"</SPAN -> when creating your patch. This will - result in quicker acceptance of the patch. - </P -></LI -><LI -><P -> Schema Changes - </P -><P -> If you make schema changes, you should modify <TT -CLASS="filename" ->sanitycheck.cgi</TT -> - to support the new schema. All referential columns should be checked. - </P -></LI -><LI -><P -> Taint Mode - </P -><P -> All new cgis must run in Taint mode (Perl taint and DBI taint), and existing cgi's - which run in taint mode must not have taint mode turned off. - </P -></LI -><LI -><P -> Templatization - </P -><P -> Patches to Bugzilla need to support templates so they do not force user interface choices - on Bugzilla administrators. - </P -></LI -><LI -><P -> Variable Names - </P -><P -> If a variable is scoped globally (<TT -CLASS="computeroutput" ->$::variable</TT ->) - its name should be descriptive of what it contains. Local variables can be named - a bit looser, provided the context makes their content obvious. For example, - <TT -CLASS="computeroutput" ->$ret</TT -> could be used as a staging variable for a - routine's return value as the line <TT -CLASS="computeroutput" ->return $ret;</TT -> - will make it blatantly obvious what the variable holds and most likely be shown - on the same screen as <TT -CLASS="computeroutput" ->my $ret = "";</TT ->. - </P -></LI -><LI -><P -> Cross Database Compatability - </P -><P -> 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 - <TT -CLASS="function" ->encrypt()</TT ->. - </P -></LI -><LI -><P -> Cross Platform Compatability - </P -><P -> 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. - </P -></LI -></UL -></DIV -></DIV -><DIV -CLASS="NAVFOOTER" -><HR -ALIGN="LEFT" -WIDTH="100%"><TABLE -SUMMARY="Footer navigation table" -WIDTH="100%" -BORDER="0" -CELLPADDING="0" -CELLSPACING="0" -><TR -><TD -WIDTH="33%" -ALIGN="left" -VALIGN="top" -><A -HREF="quicksearch.html" -ACCESSKEY="P" ->Prev</A -></TD -><TD -WIDTH="34%" -ALIGN="center" -VALIGN="top" -><A -HREF="index.html" -ACCESSKEY="H" ->Home</A -></TD -><TD -WIDTH="33%" -ALIGN="right" -VALIGN="top" -><A -HREF="gfdl.html" -ACCESSKEY="N" ->Next</A -></TD -></TR -><TR -><TD -WIDTH="33%" -ALIGN="left" -VALIGN="top" ->The Quicksearch Utility</TD -><TD -WIDTH="34%" -ALIGN="center" -VALIGN="top" -><A -HREF="patches.html" -ACCESSKEY="U" ->Up</A -></TD -><TD -WIDTH="33%" -ALIGN="right" -VALIGN="top" ->GNU Free Documentation License</TD -></TR -></TABLE -></DIV -></BODY -></HTML ->
