110 <sect1 id="introduction"><title>Introduction</title>
113 I don't like seeing blank space :) So added *something* here.
117 <application>Privoxy</application>, as an heir to
118 <application>Junkbuster</application>, is an Open Source project
119 and licensed under the GPL. As such, <application>Privoxy</application>
120 development is potentially open to anyone who has the time, knowledge,
121 and desire to contribute in any capacity. Our goals are simply to
122 continue the mission, to improve <application>Privoxy</application>, and
123 to make it available to as wide an audience as possible.
126 One does not have to be a programmer to contribute. Packaging, testing,
127 and porting, are all important jobs as well.
130 <!-- ~~~~~ New section ~~~~~ -->
131 <sect2 id="quickstart"><title>Quickstart to Privoxy Development</title>
133 You'll need an account on <ulink
134 url="http://sourceforge.net/">Sourceforge</ulink> to support our
135 development. Mail your ID to <ulink
136 url="mailto:developers@privoxy.org">the list</ulink> and wait until a
137 project manager has added you.
140 For the time being (read, this section is under construction), please
141 refer to the extensive comments in the source code.
146 <!-- ~~~~~ New section ~~~~~ -->
147 <sect1 id="cvs"><title>The CVS Repository</title>
149 If you intend to help us with programming, documentation or packaging
150 you will need write access to our holy grail, the CVS repository.
151 Please read this chapter completely before accessing via CVS.
154 <sect2 id="cvsaccess"><title>Access to CVS</title>
156 The project's CVS repository is hosted on
157 <ulink url="http://sourceforge.net/">SourceForge.</ulink>
158 Please refer to the chapters 6 and 7 in
159 <ulink url="http://sourceforge.net/docman/?group_id=1">SF's site
160 documentation</ulink> for the technical access details for your
161 operating system. For historical reasons, the CVS server is
162 called <literal>cvs.ijbswa.sourceforge.net</literal>, the repository is
163 called <literal>ijbswa</literal>, and the source tree module is called
164 <literal>current</literal>.
168 <sect2 id="cvscommit"><title>CVS Commit Guideline</title>
170 The source tree is the heart of every software project. Every effort must
171 be made to ensure that it is readable, compilable and consistent at all
172 times. We therefore ask anyone with CVS access to strictly adhere to the
173 following guidelines:
176 Never (read: <emphasis>never, ever</emphasis>) be tempted to commit
177 that small change without testing it thoroughly first. When we're
178 close to a public release, ask a fellow developer to review your
182 Your commit message should give a concise overview of <emphasis>what you
183 changed</emphasis> (no big details) and <emphasis>why you changed it</emphasis>
184 Just check previous messages for good examples.
187 Don't use the same message on multiple files, unless it equally applies to
191 If your changes span multiple files, and the code won't recompile unless
192 all changes are committed (e.g. when changing the signature of a function),
193 then commit all files one after another, without long delays in between.
194 If necessary, prepare the commit messages in advance.
197 Before changing things on CVS, make sure that your changes are in line
198 with the team's general consensus on what should be done (see below).
204 <sect2 id="cvswhenask"><title>Discussing Changes First</title>
206 We don't have a too formal policy on this, just use common sense. Hints: If it is..
207 <orderedlist numeration="arabic">
209 ..a bug-fix / clean-up / cosmetic thing: shoot
212 ..a new feature that can be turned off: shoot
215 ..a clear improvement w/o side effects on other parts of the code: shoot
218 ..a matter of taste: <ulink url="mailto:developers@privoxy.org">ask the list</ulink>
221 ..a major redesign of some part of the code: <ulink url="mailto:developers@privoxy.org">ask
227 Note that near a major public release, we get a bit more cautious - if
228 unsure, it doesn't hurt to ask first. There is always the possibility
229 to submit a patch to the <ulink
230 url="http://sourceforge.net/tracker/?atid=311118&group_id=11118&func=browse">patches
231 tracker</ulink> instead.
236 <!-- ~~~~~ New section ~~~~~ -->
237 <sect1 id="documentation"><title>Documentation Guidelines</title>
239 All formal documents are maintained in Docbook SGML and located in the
240 <computeroutput>doc/source/*</computeroutput> directory. You will need
241 <ulink url="http://www.docbook.org">Docbook</ulink>, the Docbook
242 DTD's and the Docbook modular stylesheets (or comparable alternatives),
243 and either <application>jade</application> or
244 <application>openjade</application> (recommended) installed in order to
245 build docs from source. Currently there is <ulink
246 url="../user-manual/index.html"><citetitle>user-manual</citetitle></ulink>,
247 <ulink url="../faq/index.html"><citetitle>FAQ</citetitle></ulink>, and, of
248 course this, the <citetitle>developer-manual</citetitle> in this format.
249 The <citetitle>README</citetitle>, <citetitle>AUTHORS</citetitle>
250 <citetitle>privoxy.1</citetitle> (man page), and
251 <citetitle>config</citetitle> files are also now maintained as Docbook
252 SGML. These files, when built, in the top-level source directory are
253 generated files! Also, the <application>Privoxy</application> <filename>index.html</filename> (and a
254 variation on this file, <filename>privoxy-index.html</filename>,
255 meant for inclusion with doc packages), are maintained as SGML as well.
256 <emphasis>DO NOT edit these directly</emphasis>. Edit the SGML source, or
257 contact someone involved in the documentation (at present Stefan and
261 <filename>config</filename> requires some special handling. The reason it
262 is maintained this way is so that the extensive comments in the file
263 mirror those in <citetitle>user-manual</citetitle>. But the conversion
264 process requires going from SGML to HTML to text to special formatting
265 required for the embedded comments. Some of this does not survive so
266 well. Especially some of the examples that are longer than 80 characters.
267 The build process for this file outputs to <filename>config.new</filename>,
268 which should be reviewed for errors and mis-formatting. Once satisfied
269 that it is correct, then it should be hand copied to
270 <filename>config</filename>.
274 Other, less formal documents (e.g. <filename>LICENSE</filename>,
275 <filename>INSTALL</filename>) are maintained as plain text files in the
276 top-level source directory. At least for the time being.
279 Packagers are encouraged to include this documentation. For those without
280 the ability to build the docs locally, text versions of each are kept in
281 CVS. HTML versions are also now being kept in CVS under
282 <filename>doc/webserver/*</filename>.
285 Formal documents are built with the Makefile targets of
286 <computeroutput>make dok</computeroutput>, or alternately
287 <computeroutput>make redhat-dok</computeroutput>. If you have problems,
288 try both. The build process uses the document SGML sources in
289 <computeroutput>doc/source/*/*</computeroutput> to update all text files in
290 <computeroutput>doc/text/</computeroutput> and to update all HTML
291 documents in <computeroutput>doc/webserver/</computeroutput>.
294 Documentation writers should please make sure documents build
295 successfully before committing to CVS, if possible.
298 How do you update the webserver (i.e. the pages on privoxy.org)?
300 <orderedlist numeration="arabic">
302 First, build the docs by running <computeroutput>make
303 dok</computeroutput> (or alternately <computeroutput>make
304 redhat-dok</computeroutput>).
307 Run <computeroutput>make webserver</computeroutput> which copies all
308 files from <computeroutput>doc/webserver</computeroutput> to the
309 sourceforge webserver via scp.
315 Finished docs should be occasionally submitted to CVS
316 (<filename>doc/webserver/*/*.html</filename>) so that those without
317 the ability to build them locally, have access to them if needed.
318 This is especially important just prior to a new release! Please
319 do this <emphasis>after</emphasis> the <literal>$VERSION</literal> and
320 other release specific data in <filename>configure.in</filename> has been
321 updated (this is done just prior to a new release).
324 <!-- ~~~~~ New section ~~~~~ -->
326 <title>Quickstart to Docbook and SGML</title>
328 If you are not familiar with SGML, it is a markup language similar to HTML.
329 Actually, not a mark up language per se, but a language used to define
330 markup languages. In fact, HTML is an SGML application. Both will use
331 <quote>tags</quote> to format text and other content. SGML tags can be much
332 more varied, and flexible, but do much of the same kinds of things. The tags,
333 or <quote>elements</quote>, are definable in SGML. There is no set
334 <quote>standards</quote>. Since we are using
335 <application>Docbook</application>, our tags are those that are defined by
336 <application>Docbook</application>. Much of how the finish document is
337 rendered is determined by the <quote>stylesheets</quote>.
338 The stylesheets determine how each tag gets translated to HTML, or other
343 Tags in Docbook SGML need to be always <quote>closed</quote>. If not, you
344 will likely generate errors. Example: <literal><title>My
345 Title</title></literal>. They are also case-insensitive, but we
346 strongly suggest using all lower case. This keeps compatibility with
347 [Docbook] <application>XML</application>.
351 Our documents use <quote>sections</quote> for the most part. Sections
352 will be processed into HTML headers (e.g. <literal>h1</literal> for
353 <literal>sect1</literal>). The <application>Docbook</application> stylesheets
354 will use these to also generate the Table of Contents for each doc. Our
355 TOC's are set to a depth of three. Meaning <literal>sect1</literal>,
356 <literal>sect2</literal>, and <literal>sect3</literal> will have TOC
357 entries, but <literal>sect4</literal> will not. Each section requires
358 a <literal><title></literal> element, and at least one
359 <literal><para></literal>. There is a limit of five section
360 levels in Docbook, but generally three should be sufficient for our
365 Some common elements that you likely will use:
371 <emphasis><para></para></emphasis>, paragraph delimiter. Most
372 text needs to be within paragraph elements (there are some exceptions).
375 <emphasis><emphasis></emphasis></emphasis>, the stylesheets
379 <emphasis><filename></filename></emphasis>, files and directories.
382 <emphasis><command></command></emphasis>, command examples.
385 <emphasis><literallayout></literallayout></emphasis>, like
386 <literal><pre></literal>, more or less.
389 <emphasis><itemizedlist></itemizedlist></emphasis>, list with bullets.
392 <emphasis><listitem></listitem></emphasis>, member of the above.
395 <emphasis><screen></screen></emphasis>, screen output, implies
396 <literal><literallayout></literal>.
399 <emphasis><ulink url="example.com"></ulink></emphasis>, like
400 HTML <literal><a></literal> tag.
403 <emphasis><quote></quote></emphasis>, for, doh, quoting text.
409 Look at any of the existing docs for examples of all these and more.
413 You might also find <quote><ulink
414 url="http://www.bureau-cornavin.com/opensource/crash-course/">Writing Documentation
415 Using DocBook - A Crash Course</ulink></quote> useful.
419 <!-- ~~~~~ New section ~~~~~ -->
420 <sect2 id="docstyle">
421 <title><application>Privoxy</application> Documentation Style</title>
423 It will be easier if everyone follows a similar writing style. This
424 just makes it easier to read what someone else has written if it
425 is all done in a similar fashion.
434 All tags should be lower case.
439 Tags delimiting a <emphasis>block</emphasis> of text (even small
440 blocks) should be on their own line. Like:
446 Tags marking individual words, or few words, should be in-line:
448 Just to <emphasis>emphasize</emphasis>, some text goes here.
454 Tags should be nested and step indented for block text like: (except
461 Some text goes here in our list example.
464 </itemizedlist>
467 This makes it easier to find the text amongst the tags ;-)
472 Use white space to separate logical divisions within a document,
473 like between sections. Running everything together consistently
474 makes it harder to read and work on.
479 Do not hesitate to make comments. Comments can either use the
480 <comment> element, or the <!-- --> style comment
481 familiar from HTML. (Note in Docbook v4.x <comment> is
482 replaced by <remark>.)
487 We have an international audience. Refrain from slang, or English
488 idiosyncrasies (too many to list :). Humor also does not translate
494 Try to keep overall line lengths in source files to 80 characters or less
495 for obvious reasons. This is not always possible, with lengthy URLs for
501 Our documents are available in differing formats. Right now, they
502 are just plain text, and HTML, but PDF, and others is always a
503 future possibility. Be careful with URLs (<ulink>), and avoid
507 My favorite site is <ulink url="http://example.com">here</ulink>.
510 This will render as <quote>My favorite site is here</quote>, which is
511 not real helpful in a text doc. Better like this:
514 My favorite site is <ulink url="http://example.com">example.com</ulink>.
519 All documents should be spell checked occasionally.
520 <application>aspell</application> can check SGML with the
521 <literal>-H</literal> option. (<application>ispell</application> I think
532 <!-- ~~~~~ New section ~~~~~ -->
534 <sect2><title>Privoxy Custom Entities</title>
536 <application>Privoxy</application> documentation is using
537 a number of customized <quote>entities</quote> to facilitate
538 documentation maintenance.
541 We are using a set of <quote>boilerplate</quote> files with generic text,
542 that is used by multiple docs. This way we can write something once, and use
543 it repeatedly without having to re-write the same content over and over again.
544 If editing such a file, keep in mind that it should be
545 <emphasis>generic</emphasis>. That is the purpose; so it can be used in varying
546 contexts without additional modifications.
549 We are also using what <application>Docbook</application> calls
550 <quote>internal entities</quote>. These are like variables in
551 programming. Well, sort of. For instance, we have the
552 <literal>p-version</literal> entity that contains the current
553 <application>Privoxy</application> version string. You are strongly
554 encouraged to use these where possible. Some of these obviously
555 require re-setting with each release (done by the Makefile). A sampling of
556 custom entities are listed below. See any of the main docs for examples.
563 Re- <quote>boilerplate</quote> text entities are defined like:
566 <literal><!entity supported SYSTEM "supported.sgml"></literal>
569 In this example, the contents of the file,
570 <filename>supported.sgml</filename> is available for inclusion anywhere
571 in the doc. To make this happen, just reference the now defined
572 entity: <literal>&supported;</literal> (starts with an ampersand
573 and ends with a semi-colon), and the contents will be dumped into
574 the finished doc at that point.
579 Commonly used <quote>internal entities</quote>:
583 <emphasis>p-version</emphasis>: the <application>Privoxy</application>
584 version string, e.g. <quote>&p-version;</quote>.
587 <emphasis>p-status</emphasis>: the project status, either
588 <quote>alpha</quote>, <quote>beta</quote>, or <quote>stable</quote>.
591 <emphasis>p-not-stable</emphasis>: use to conditionally include
592 text in <quote>not stable</quote> releases (e.g. <quote>beta</quote>).
595 <emphasis>p-stable</emphasis>: just the opposite.
598 <emphasis>p-text</emphasis>: this doc is only generated as text.
605 There are others in various places that are defined for a specific
606 purpose. Read the source!

637 <sect3 id="s3"><title>Comment, Comment, Comment</title>
639 <para><emphasis>Explanation:</emphasis></para>
641 <para>Comment as much as possible without commenting the obvious.
642 For example do not comment "aVariable is equal to bVariable".
643 Instead explain why aVariable should be equal to the bVariable.
644 Just because a person can read code does not mean they will
645 understand why or what is being done. A reader may spend a lot
646 more time figuring out what is going on when a simple comment
647 or explanation would have prevented the extra research. Please
648 help your brother IJB'ers out!</para>
650 <para>The comments will also help justify the intent of the code.
651 If the comment describes something different than what the code
652 is doing then maybe a programming error is occurring.</para>
654 <para><emphasis>Example:</emphasis></para>
656 /* if page size greater than 1k ... */
657 if ( PageLength() > 1024 )
659 ... "block" the page up ...
662 /* if page size is small, send it in blocks */
663 if ( PageLength() > 1024 )
665 ... "block" the page up ...
668 This demonstrates 2 cases of "what not to do". The first is a
669 "syntax comment". The second is a comment that does not fit what
670 is actually being done.
676 <sect3 id="s4"><title>Use blocks for comments</title>
678 <para><emphasis>Explanation:</emphasis></para>
680 <para>Comments can help or they can clutter. They help when they
681 are differentiated from the code they describe. One line
682 comments do not offer effective separation between the comment
683 and the code. Block identifiers do, by surrounding the code
684 with a clear, definable pattern.</para>

711 <para>If you are trying to add a small logic comment and do not
712 wish to "disrupt" the flow of the code, feel free to use a 1

719 <sect3 id="s5"><title>Keep Comments on their own line</title>
721 <para><emphasis>Explanation:</emphasis></para>
723 <para>It goes back to the question of readability. If the comment

725 the comment that is on its own line.</para>

796 <para>A reader of the code should be able to look at the comments
797 just prior to the beginning of a function and discern the
798 reason for its existence and the consequences of using it. The
799 reader should not have to read through the code to determine if
800 a given function is safe for a desired use. The proper
801 information thoroughly presented at the introduction of a
802 function not only saves time for subsequent maintenance or
803 debugging, it more importantly aids in code reuse by allowing a
804 user to determine the safety and applicability of any function
805 for the problem at hand. As a result of such benefits, all
806 functions should contain the information presented in the

1301 for ( size_t cnt = 0; cnt < blockListLength(); cnt ++ )
1306 <para><emphasis>Note:</emphasis> Unfortunately, this makes a function call for
1307 each and every iteration. This increases the overhead in the
1308 program, because the compiler has to look up the function each

1310 the blockListLength() call, it might even be creating and
1311 destroying structures with each iteration, even though in each

1362 <para>Most structures cannot fit onto a normal stack entry (i.e.

1955 <sect1 id="newrelease"><title>Releasing a New Version</title>
1957 When we release versions of <application>Privoxy</application>,
1958 our work leaves our cozy secret lab and has to work in the cold
1959 RealWorld[tm]. Once it is released, there is no way to call it
1960 back, so it is very important that great care is taken to ensure
1961 that everything runs fine, and not to introduce problems in the
1965 So when releasing a new version, please adhere exactly to the
1966 procedure outlined in this chapter.
1970 The following programs are required to follow this process:
1971 <filename>ncftpput</filename> (ncftp), <filename>scp, ssh</filename> (ssh),
1972 <filename>gmake</filename> (GNU's version of make), autoconf, cvs.
1975 <sect2 id="versionnumbers">
1976 <title>Version numbers</title>
1979 First you need to determine which version number the release will have.
1980 <application>Privoxy</application> version numbers consist of three numbers,
1981 separated by dots, like in X.Y.Z, where:
1985 X, the version major, is rarely ever changed. It is increased by one if
1986 turning a development branch into stable substantially changes the functionality,
1987 user interface or configuration syntax. Majors 1 and 2 were
1988 <application>Junkbuster</application>, and 3 will be the first stable
1989 <application>Privoxy</application> release.
1994 Y, the version minor, represents the branch within the major version.
1995 At any point in time, there are two branches being maintained:
1996 The stable branch, with an even minor, say, 2N, in which no functionality is
1997 being added and only bug-fixes are made, and 2N+1, the development branch, in
1998 which the further development of <application>Privoxy</application> takes
2000 This enables us to turn the code upside down and inside out, while at the same time
2001 providing and maintaining a stable version.
2002 The minor is reset to zero (and one) when the major is incremented. When a development
2003 branch has matured to the point where it can be turned into stable, the old stable branch
2004 2N is given up (i.e. no longer maintained), the former development branch 2N+1 becomes the
2005 new stable branch 2N+2, and a new development branch 2N+3 is opened.
2010 Z, the point or sub version, represents a release of the software within a branch.
2011 It is therefore incremented immediately before each code freeze.
2012 In development branches, only the even point versions correspond to actual releases,
2013 while the odd ones denote the evolving state of the sources on CVS in between.
2014 It follows that Z is odd on CVS in development branches most of the time. There, it gets
2015 increased to an even number immediately before a code freeze, and is increased to an odd
2016 number again immediately thereafter.
2017 This ensures that builds from CVS snapshots are easily distinguished from released versions.
2018 The point version is reset to zero when the minor changes.
2026 <sect2 id="beforerelease">
2027 <title>Before the Release: Freeze</title>
2029 The following <emphasis>must be done by one of the
2030 developers</emphasis> prior to each new release.
2036 Make sure that everybody who has worked on the code in the last
2037 couple of days has had a chance to yell <quote>no!</quote> in case
2038 they have pending changes/fixes in their pipelines. Announce the
2039 freeze so that nobody will interfere with last minute changes.
2044 Increment the version number (point from odd to even in development
2045 branches!) in <filename>configure.in</filename>.
2050 If <filename>default.action</filename> has changed since last
2051 release (i.e. software release or standalone actions file release),
2052 bump up its version info to A.B in this line:
2056 {+add-header{X-Actions-File-Version: A.B} -filter -no-popups}
2060 Then change the version info in doc/webserver/actions/index.php,
2061 line: '$required_actions_file_version = "A.B";'
2066 If the HTML documentation is not in sync with the SGML sources
2067 you need to regenerate and upload it to the webserver. (If in
2068 doubt, just do it.) See the Section "Updating the webserver" in
2069 this manual for details.
2074 <emphasis>Commit all files that were changed in the above steps!</emphasis>
2079 Tag all files in CVS with the version number with
2080 <quote><command>cvs tag v_X_Y_Z</command></quote>.
2081 Don't use vX_Y_Z, ver_X_Y_Z, v_X.Y.Z (won't work) etc.
2086 If the release was in a development branch, increase the point version
2087 from even to odd (X.Y.(Z+1)) again in <filename>configure.in</filename> and
2093 On the webserver, copy the user manual to a new top-level directory
2094 called <filename>X.Y.Z</filename>. This ensures that help links from the CGI
2095 pages, which have the version as a prefix, will go into the right version of the manual.
2096 If this is a development branch release, also symlink <filename>X.Y.(Z-1)</filename>
2097 to <filename>X.Y.Z</filename> and <filename>X.Y.(Z+1)</filename> to
2098 <filename>.</filename> (i.e. dot).
2105 <sect2 id="therelease">
2106 <title>Building and Releasing the Packages</title>
2108 Now the individual packages can be built and released. Note that for
2109 GPL reasons the first package to be released is always the source tarball.
2113 For <emphasis>all</emphasis> types of packages, including the source tarball,
2114 <emphasis>you must make sure that you build from clean sources by exporting
2115 the right version from CVS into an empty directory:</emphasis>.
2120 mkdir dist # delete or choose different name if it already exists
2122 cvs -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa login
2123 cvs -z3 -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa export -r v_X_Y_Z current
2128 <emphasis>Do NOT change</emphasis> a single bit, including, but not limited to
2129 version information after export from CVS. This is to make sure that
2130 all release packages, and with them, all future bug reports, are based
2131 on exactly the same code.
2135 Please find additional instructions for the source tarball and the
2136 individual platform dependent binary packages below. And details
2137 on the Sourceforge release process below that.
2140 <sect3 id="pack-guidelines">
2141 <title>Note on Privoxy Packaging</title>
2143 Please keep these general guidelines in mind when putting together
2144 your package. These apply to <emphasis>all</emphasis> platforms!
2150 <application>Privoxy</application> <emphasis>requires</emphasis>
2151 write access to: all <filename>*.action</filename> files, all
2152 logfiles, and the <filename>trust</filename> file. You will
2153 need to determine the best way to do this for your platform.
2158 Please include up to date documentation. At a bare minimum:
2162 <filename>LICENSE</filename> (top-level directory)
2167 <filename>README</filename> (top-level directory)
2172 <filename>AUTHORS</filename> (top-level directory)
2177 <filename>man page</filename> (top-level directory, Unix-like
2183 <filename>The User Manual</filename> (doc/webserver/user-manual/)
2188 <filename>FAQ</filename> (doc/webserver/faq/)
2192 Also suggested: <filename>Developer Manual</filename>
2193 (doc/webserver/developer-manual) and <filename>ChangeLog</filename>
2194 (top-level directory). <filename>FAQ</filename> and the manuals are
2195 HTML docs. There are also text versions in

2200 The documentation has been designed such that the manuals are linked
2201 to each other from parallel directories, and should be packaged
2202 that way. <filename>privoxy-index.html</filename> can also be
2203 included and can serve as a focal point for docs and other links of
2204 interest (and possibly renamed to <filename>index.html</filename>).
2205 This should be one level up from the manuals. There is a link also
2206 on this page to an HTMLized version of the man page. To avoid 404 for
2207 this, it is in CVS as
2208 <filename>doc/webserver/man-page/privoxy-man-page.html</filename>,
2209 and should be included along with the manuals. There is also a
2210 css stylesheets that can be included for better presentation:
2211 <filename>p_doc.css</filename>. This should be in the same directory
2212 with <filename>privoxy-index.html</filename>, (i.e. one level up from
2213 the manual directories).
2218 <filename>user.action</filename> is designed for local preferences.
2219 Make sure this does not get overwritten!
2224 Other configuration files should be installed as the new defaults,
2225 but all previously installed configuration files should be preserved
2226 as backups. This is just good manners :-)
2231 Please check platform specific notes in this doc, if you haven't
2232 done <quote>Privoxy</quote> packaging before for other platform
2233 specific issues. Conversely, please add any notes that you know
2234 are important for your platform (or contact one of the doc
2235 maintainers to do this if you can't).

2330 Use the release notes and change log from the source tarball package.
2334 <sect3 id="newrelease-os2"><title>OS/2</title>
2336 First, <emphasis>make sure that you have freshly exported the right
2337 version into an empty directory</emphasis>. (See "Building and releasing
2338 packages" above). Then get the OS/2 Setup module:
2342 cvs -z3 -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa co os2setup
2346 You will need a mix of development tools.
2347 The main compilation takes place with IBM Visual Age C++.
2348 Some ancillary work takes place with GNU tools, available from
2349 various sources like hobbes.nmsu.edu.
2350 Specificially, you will need <filename>autoheader</filename>,
2351 <filename>autoconf</filename> and <filename>sh</filename> tools.
2352 The packaging takes place with WarpIN, available from various sources, including
2353 its home page: <ulink url="http://www.xworkplace.org/">xworkplace</ulink>.
2356 Change directory to the <filename>os2setup</filename> directory.
2357 Edit the os2build.cmd file to set the final executable filename.
2362 installExeName='privoxyos2_setup_X.Y.Z.exe'
2366 Next, edit the <filename>IJB.wis</filename> file so the release number matches
2367 in the <filename>PACKAGEID</filename> section:
2371 PACKAGEID="Privoxy Team\Privoxy\Privoxy Package\X\Y\Z"
2375 You're now ready to build. Run:
2383 You will find the WarpIN-installable executable in the
2384 <filename>./files</filename> directory. Upload this anonymously to
2385 <filename>uploads.sourceforge.net/incoming</filename>, create a release
2386 for it, and you're done. Use the release notes and Change Log from the
2387 source tarball package.
2391 <sect3 id="newrelease-solaris"><title>Solaris</title>
2393 Login to Sourceforge's compilefarm via ssh:
2397 ssh cf.sourceforge.net
2401 Choose the right operating system (not the Debian one).
2402 When logged in, <emphasis>make sure that you have freshly exported the right
2403 version into an empty directory</emphasis>. (See "Building and releasing
2404 packages" above). Then run:
2409 autoheader && autoconf && ./configure
2421 which creates a gzip'ed tar archive. Sadly, you cannot use <command>make
2422 solaris-upload</command> on the Sourceforge machine (no ncftpput). You now have
2423 to manually upload the archive to Sourceforge's ftp server and release
2424 the file publicly. Use the release notes and Change Log from the
2425 source tarball package.
2429 <sect3 id="newrelease-windows"><title>Windows</title>
2431 You should ensure you have the latest version of Cygwin (from
2432 <ulink url="http://www.cygwin.com/">http://www.cygwin.com/</ulink>).
2433 Run the following commands from within a Cygwin bash shell.
2436 First, <emphasis>make sure that you have freshly exported the right
2437 version into an empty directory</emphasis>. (See "Building and releasing
2438 packages" above). Then get the Windows setup module:
2442 cvs -z3 -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa co winsetup
2446 Then you can build the package. This is fully automated, and is
2447 controlled by <filename>winsetup/GNUmakefile</filename>.
2448 All you need to do is:
2457 Now you can manually rename <filename>privoxy_setup.exe</filename> to
2458 <filename>privoxy_setup_X_Y_Z.exe</filename>, and upload it to
2459 SourceForge. When releasing the package on SourceForge, use the release notes
2460 and Change Log from the source tarball package.
2464 <sect3 id="newrelease-debian"><title>Debian</title>
2466 First, <emphasis>make sure that you have freshly exported the
2467 right version into an empty directory</emphasis>. (See
2468 "Building and releasing packages" above). Then add a log
2469 entry to <filename>debian/changelog</filename>, if it is not
2470 already there, for example by running:

2500 First, <emphasis>make sure that you have freshly exported the right
2501 version into an empty directory</emphasis>. (See "Building and releasing
2502 packages" above). Then get the Mac OSX setup module:
2506 cvs -z3 -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa co osxsetup
2519 This will run <filename>autoheader</filename>, <filename>autoconf</filename> and
2520 <filename>configure</filename> as well as <filename>make</filename>.
2521 Finally, it will copy over the necessary files to the ./osxsetup/files directory
2522 for further processing by <filename>PackageMaker</filename>.
2525 Bring up PackageMaker with the PrivoxyPackage.pmsp definition file, modify the package
2526 name to match the release, and hit the "Create package" button.
2527 If you specify ./Privoxy.pkg as the output package name, you can then create
2528 the distributable zip file with the command:
2532 zip -r privoxyosx_setup_x.y.z.zip Privoxy.pkg
2536 You can then upload <filename>privoxyosx_setup_x.y.z.zip</filename> anonymously to
2537 <filename>uploads.sourceforge.net/incoming</filename>,
2538 create a release for it, and you're done. Use the release notes
2539 and Change Log from the source tarball package.

2688 of <literal>$VERSION ($CODE_STATUS)</literal>, e.g. <emphasis>&p-version;

2725 <sect1 id="webserver-update"><title>Update the Webserver</title>
2727 When updating the webserver, please follow these steps to make
2728 sure that no broken links, inconsistent contents or permission
2729 problems will occur:
2732 If you have changed anything in the documentation source SGML files,
2737 make dok # (or make redhat-dok if make dok doesn't work for you)
2741 That will generate <filename>doc/webserver/user-manual</filename>,
2742 <filename>doc/webserver/developer-manual</filename>,
2743 <filename>doc/webserver/faq</filename> and
2744 <filename>doc/webserver/index.html</filename> automatically.
2747 If you changed the manual page source, generate
2748 <filename>doc/webserver/man-page/privoxy-man-page.html</filename>
2749 by running <quote><command>make man</command></quote>. (This is
2750 a separate target due to dependencies on some obscure perl scripts.
2751 See comments in <filename>GNUmakefile</filename>.)
2754 If you want to add new files to the webserver, create them locally in
2755 the <filename>doc/webserver/*</filename> directory (or
2756 create new directories under <filename>doc/webserver</filename>).
2759 Next, commit any changes from the above steps to CVS. All set? Then do
2767 This will do the upload to <ulink url="http://www.privoxy.org/">the
2768 webserver</ulink> (www.privoxy.org) and ensure all files and directories
2769 there are group writable.
2772 Please do <emphasis>NOT</emphasis> use any other means of transferring
2773 files to the webserver to avoid permission problems.
