114 <sect1 id="introduction"><title>Introduction</title>
117 I don't like seeing blank space :) So added *something* here.
121 <application>Privoxy</application>, as an heir to
122 <application>Junkbuster</application>, is an Open Source project
123 and licensed under the GPL. As such, <application>Privoxy</application>
124 development is potentially open to anyone who has the time, knowledge,
125 and desire to contribute in any capacity. Our goals are simply to
126 continue the mission, to improve <application>Privoxy</application>, and
127 to make it available to as wide an audience as possible.
130 One does not have to be a programmer to contribute. Packaging, testing,
131 and porting, are all important jobs as well.
134 <!-- ~~~~~ New section ~~~~~ -->
135 <sect2 id="quickstart"><title>Quickstart to Privoxy Development</title>
137 You'll need an account on <ulink
138 url="http://sourceforge.net/">Sourceforge</ulink> to support our
139 development. Mail your ID to <ulink
140 url="mailto:developers@privoxy.org">the list</ulink> and wait until a
141 project manager has added you.
144 For the time being (read, this section is under construction), please
145 refer to the extensive comments in the source code.
150 <!-- ~~~~~ New section ~~~~~ -->
151 <sect1 id="cvs"><title>The CVS Repository</title>
153 If you intend to help us with programming, documentation or packaging
154 you will need write access to our holy grail, the CVS repository.
155 Please read this chapter completely before accessing via CVS.
158 <sect2 id="cvsaccess"><title>Access to CVS</title>
160 The project's CVS repository is hosted on
161 <ulink url="http://sourceforge.net/">SourceForge.</ulink>
162 Please refer to the chapters 6 and 7 in
163 <ulink url="http://sourceforge.net/docman/?group_id=1">SF's site
164 documentation</ulink> for the technical access details for your
165 operating system. For historical reasons, the CVS server is
166 called <literal>cvs.ijbswa.sourceforge.net</literal>, the repository is
167 called <literal>ijbswa</literal>, and the source tree module is called
168 <literal>current</literal>.
172 <sect2 id="cvscommit"><title>CVS Commit Guideline</title>
174 The source tree is the heart of every software project. Every effort must
175 be made to ensure that it is readable, compilable and consistent at all
176 times. We therefore ask anyone with CVS access to strictly adhere to the
177 following guidelines:
180 Never (read: <emphasis>never, ever</emphasis>) be tempted to commit
181 that small change without testing it thoroughly first. When we're
182 close to a public release, ask a fellow developer to review your
186 Your commit message should give a concise overview of <emphasis>what you
187 changed</emphasis> (no big details) and <emphasis>why you changed it</emphasis>
188 Just check previous messages for good examples.
191 Don't use the same message on multiple files, unless it equally applies to
195 If your changes span multiple files, and the code won't recompile unless
196 all changes are committed (e.g. when changing the signature of a function),
197 then commit all files one after another, without long delays in between.
198 If necessary, prepare the commit messages in advance.
201 Before changing things on CVS, make sure that your changes are in line
202 with the team's general consensus on what should be done (see below).
205 Don't commit into the stable branch, unless immediately before a new
206 release. (See <link linkend="versionnumbers">Version Numbers</link> below
207 for details.) Collect your changes on the <ulink
208 url="http://sourceforge.net/tracker/?atid=311118&group_id=11118&func=browse">patches
209 tracker</ulink> instead.
215 <sect2 id="cvswhenask"><title>Discussing Changes First</title>
217 We don't have a too formal policy on this, just use common sense. Hints: If it is..
218 <orderedlist numeration="arabic">
220 ..a bug-fix / clean-up / cosmetic thing: shoot
223 ..a new feature that can be turned off: shoot
226 ..a clear improvement w/o side effects on other parts of the code: shoot
229 ..a matter of taste: <ulink url="mailto:developers@privoxy.org">ask the list</ulink>
232 ..a major redesign of some part of the code: <ulink url="mailto:developers@privoxy.org">ask
238 Note that near a major public release, we get a bit more cautious - if
239 unsure, it doesn't hurt to ask first. There is always the possibility
240 to submit a patch to the <ulink
241 url="http://sourceforge.net/tracker/?atid=311118&group_id=11118&func=browse">patches
242 tracker</ulink> instead.
247 <!-- ~~~~~ New section ~~~~~ -->
248 <sect1 id="documentation"><title>Documentation Guidelines</title>
250 All formal documents are maintained in Docbook SGML and located in the
251 <computeroutput>doc/source/*</computeroutput> directory. You will need
252 <ulink url="http://www.docbook.org">Docbook</ulink>, the Docbook
253 DTD's and the Docbook modular stylesheets (or comparable alternatives),
254 and either <application>jade</application> or
255 <application>openjade</application> (recommended) installed in order to
256 build docs from source. Currently there is <ulink
257 url="../user-manual/index.html"><citetitle>user-manual</citetitle></ulink>,
258 <ulink url="../faq/index.html"><citetitle>FAQ</citetitle></ulink>, and, of
259 course this, the <citetitle>developer-manual</citetitle> in this format.
260 The <citetitle>README</citetitle>, <citetitle>AUTHORS</citetitle>
261 <citetitle>privoxy.1</citetitle> (man page), and
262 <citetitle>config</citetitle> files are also now maintained as Docbook
263 SGML. These files, when built, in the top-level source directory are
264 generated files! Also, the <application>Privoxy</application> <filename>index.html</filename> (and a
265 variation on this file, <filename>privoxy-index.html</filename>,
266 meant for inclusion with doc packages), are maintained as SGML as well.
267 <emphasis>DO NOT edit these directly</emphasis>. Edit the SGML source, or
268 contact someone involved in the documentation (at present Stefan and
272 <filename>config</filename> requires some special handling. The reason it
273 is maintained this way is so that the extensive comments in the file
274 mirror those in <citetitle>user-manual</citetitle>. But the conversion
275 process requires going from SGML to HTML to text to special formatting
276 required for the embedded comments. Some of this does not survive so
277 well. Especially some of the examples that are longer than 80 characters.
278 The build process for this file outputs to <filename>config.new</filename>,
279 which should be reviewed for errors and mis-formatting. Once satisfied
280 that it is correct, then it should be hand copied to
281 <filename>config</filename>.
285 Other, less formal documents (e.g. <filename>LICENSE</filename>,
286 <filename>INSTALL</filename>) are maintained as plain text files in the
287 top-level source directory. At least for the time being.
290 Packagers are encouraged to include this documentation. For those without
291 the ability to build the docs locally, text versions of each are kept in
292 CVS. HTML versions are also now being kept in CVS under
293 <filename>doc/webserver/*</filename>.
296 Formal documents are built with the Makefile targets of
297 <computeroutput>make dok</computeroutput>, or alternately
298 <computeroutput>make redhat-dok</computeroutput>. If you have problems,
299 try both. The build process uses the document SGML sources in
300 <computeroutput>doc/source/*/*</computeroutput> to update all text files in
301 <computeroutput>doc/text/</computeroutput> and to update all HTML
302 documents in <computeroutput>doc/webserver/</computeroutput>.
305 Documentation writers should please make sure documents build
306 successfully before committing to CVS, if possible.
309 How do you update the webserver (i.e. the pages on privoxy.org)?
311 <orderedlist numeration="arabic">
313 First, build the docs by running <computeroutput>make
314 dok</computeroutput> (or alternately <computeroutput>make
315 redhat-dok</computeroutput>).
318 Run <computeroutput>make webserver</computeroutput> which copies all
319 files from <computeroutput>doc/webserver</computeroutput> to the
320 sourceforge webserver via scp.
326 Finished docs should be occasionally submitted to CVS
327 (<filename>doc/webserver/*/*.html</filename>) so that those without
328 the ability to build them locally, have access to them if needed.
329 This is especially important just prior to a new release! Please
330 do this <emphasis>after</emphasis> the <literal>$VERSION</literal> and
331 other release specific data in <filename>configure.in</filename> has been
332 updated (this is done just prior to a new release).

337 <title>Quickstart to Docbook and SGML</title>
339 If you are not familiar with SGML, it is a markup language similar to HTML.
340 Actually, not a mark up language per se, but a language used to define
341 markup languages. In fact, HTML is an SGML application. Both will use
342 <quote>tags</quote> to format text and other content. SGML tags can be much
343 more varied, and flexible, but do much of the same kinds of things. The tags,
344 or <quote>elements</quote>, are definable in SGML. There is no set
345 <quote>standards</quote>. Since we are using
346 <application>Docbook</application>, our tags are those that are defined by
347 <application>Docbook</application>. Much of how the finish document is
348 rendered is determined by the <quote>stylesheets</quote>.
349 The stylesheets determine how each tag gets translated to HTML, or other
354 Tags in Docbook SGML need to be always <quote>closed</quote>. If not, you
355 will likely generate errors. Example: <literal><title>My
356 Title</title></literal>. They are also case-insensitive, but we
357 strongly suggest using all lower case. This keeps compatibility with
358 [Docbook] <application>XML</application>.
362 Our documents use <quote>sections</quote> for the most part. Sections
363 will be processed into HTML headers (e.g. <literal>h1</literal> for
364 <literal>sect1</literal>). The <application>Docbook</application> stylesheets
365 will use these to also generate the Table of Contents for each doc. Our
366 TOC's are set to a depth of three. Meaning <literal>sect1</literal>,
367 <literal>sect2</literal>, and <literal>sect3</literal> will have TOC
368 entries, but <literal>sect4</literal> will not. Each section requires
369 a <literal><title></literal> element, and at least one
370 <literal><para></literal>. There is a limit of five section
371 levels in Docbook, but generally three should be sufficient for our
376 Some common elements that you likely will use:
382 <emphasis><para></para></emphasis>, paragraph delimiter. Most
383 text needs to be within paragraph elements (there are some exceptions).
386 <emphasis><emphasis></emphasis></emphasis>, the stylesheets
390 <emphasis><filename></filename></emphasis>, files and directories.
393 <emphasis><command></command></emphasis>, command examples.
396 <emphasis><literallayout></literallayout></emphasis>, like
397 <literal><pre></literal>, more or less.
400 <emphasis><itemizedlist></itemizedlist></emphasis>, list with bullets.
403 <emphasis><listitem></listitem></emphasis>, member of the above.
406 <emphasis><screen></screen></emphasis>, screen output, implies
407 <literal><literallayout></literal>.
410 <emphasis><ulink url="example.com"></ulink></emphasis>, like
411 HTML <literal><a></literal> tag.
414 <emphasis><quote></quote></emphasis>, for, doh, quoting text.
420 Look at any of the existing docs for examples of all these and more.
424 You might also find <quote><ulink
425 url="http://www.bureau-cornavin.com/opensource/crash-course/">Writing Documentation
426 Using DocBook - A Crash Course</ulink></quote> useful.
430 <!-- ~~~~~ New section ~~~~~ -->
431 <sect2 id="docstyle">
432 <title><application>Privoxy</application> Documentation Style</title>
434 It will be easier if everyone follows a similar writing style. This
435 just makes it easier to read what someone else has written if it
436 is all done in a similar fashion.
445 All tags should be lower case.
450 Tags delimiting a <emphasis>block</emphasis> of text (even small
451 blocks) should be on their own line. Like:
457 Tags marking individual words, or few words, should be in-line:
459 Just to <emphasis>emphasize</emphasis>, some text goes here.
465 Tags should be nested and step indented for block text like: (except
472 Some text goes here in our list example.
475 </itemizedlist>
478 This makes it easier to find the text amongst the tags ;-)
483 Use white space to separate logical divisions within a document,
484 like between sections. Running everything together consistently
485 makes it harder to read and work on.
490 Do not hesitate to make comments. Comments can either use the
491 <comment> element, or the <!-- --> style comment
492 familiar from HTML. (Note in Docbook v4.x <comment> is
493 replaced by <remark>.)
498 We have an international audience. Refrain from slang, or English
499 idiosyncrasies (too many to list :). Humor also does not translate
505 Try to keep overall line lengths in source files to 80 characters or less
506 for obvious reasons. This is not always possible, with lengthy URLs for
512 Our documents are available in differing formats. Right now, they
513 are just plain text, and HTML, but PDF, and others is always a
514 future possibility. Be careful with URLs (<ulink>), and avoid
518 My favorite site is <ulink url="http://example.com">here</ulink>.
521 This will render as <quote>My favorite site is here</quote>, which is
522 not real helpful in a text doc. Better like this:
525 My favorite site is <ulink url="http://example.com">example.com</ulink>.
530 All documents should be spell checked occasionally.
531 <application>aspell</application> can check SGML with the
532 <literal>-H</literal> option. (<application>ispell</application> I think
543 <!-- ~~~~~ New section ~~~~~ -->
545 <sect2><title>Privoxy Custom Entities</title>
547 <application>Privoxy</application> documentation is using
548 a number of customized <quote>entities</quote> to facilitate
549 documentation maintenance.
552 We are using a set of <quote>boilerplate</quote> files with generic text,
553 that is used by multiple docs. This way we can write something once, and use
554 it repeatedly without having to re-write the same content over and over again.
555 If editing such a file, keep in mind that it should be
556 <emphasis>generic</emphasis>. That is the purpose; so it can be used in varying
557 contexts without additional modifications.
560 We are also using what <application>Docbook</application> calls
561 <quote>internal entities</quote>. These are like variables in
562 programming. Well, sort of. For instance, we have the
563 <literal>p-version</literal> entity that contains the current
564 <application>Privoxy</application> version string. You are strongly
565 encouraged to use these where possible. Some of these obviously
566 require re-setting with each release (done by the Makefile). A sampling of
567 custom entities are listed below. See any of the main docs for examples.
574 Re- <quote>boilerplate</quote> text entities are defined like:
577 <literal><!entity supported SYSTEM "supported.sgml"></literal>
580 In this example, the contents of the file,
581 <filename>supported.sgml</filename> is available for inclusion anywhere
582 in the doc. To make this happen, just reference the now defined
583 entity: <literal>&supported;</literal> (starts with an ampersand
584 and ends with a semi-colon), and the contents will be dumped into
585 the finished doc at that point.
590 Commonly used <quote>internal entities</quote>:
594 <emphasis>p-version</emphasis>: the <application>Privoxy</application>
595 version string, e.g. <quote>&p-version;</quote>.
598 <emphasis>p-status</emphasis>: the project status, either
599 <quote>alpha</quote>, <quote>beta</quote>, or <quote>stable</quote>.
602 <emphasis>p-not-stable</emphasis>: use to conditionally include
603 text in <quote>not stable</quote> releases (e.g. <quote>beta</quote>).
606 <emphasis>p-stable</emphasis>: just the opposite.
609 <emphasis>p-text</emphasis>: this doc is only generated as text.
616 There are others in various places that are defined for a specific
617 purpose. Read the source!

648 <sect3 id="s3"><title>Comment, Comment, Comment</title>
650 <para><emphasis>Explanation:</emphasis></para>
652 <para>Comment as much as possible without commenting the obvious.
653 For example do not comment "aVariable is equal to bVariable".
654 Instead explain why aVariable should be equal to the bVariable.
655 Just because a person can read code does not mean they will
656 understand why or what is being done. A reader may spend a lot
657 more time figuring out what is going on when a simple comment
658 or explanation would have prevented the extra research. Please
659 help your brother IJB'ers out!</para>
661 <para>The comments will also help justify the intent of the code.
662 If the comment describes something different than what the code
663 is doing then maybe a programming error is occurring.</para>
665 <para><emphasis>Example:</emphasis></para>
667 /* if page size greater than 1k ... */
668 if ( PageLength() > 1024 )
670 ... "block" the page up ...
673 /* if page size is small, send it in blocks */
674 if ( PageLength() > 1024 )
676 ... "block" the page up ...
679 This demonstrates 2 cases of "what not to do". The first is a
680 "syntax comment". The second is a comment that does not fit what
681 is actually being done.
687 <sect3 id="s4"><title>Use blocks for comments</title>
689 <para><emphasis>Explanation:</emphasis></para>
691 <para>Comments can help or they can clutter. They help when they
692 are differentiated from the code they describe. One line
693 comments do not offer effective separation between the comment
694 and the code. Block identifiers do, by surrounding the code
695 with a clear, definable pattern.</para>
697 <para><emphasis>Example:</emphasis></para>
699 /*********************************************************************

720 <para><emphasis>Exception:</emphasis></para>
722 <para>If you are trying to add a small logic comment and do not
723 wish to "disrupt" the flow of the code, feel free to use a 1

730 <sect3 id="s5"><title>Keep Comments on their own line</title>
732 <para><emphasis>Explanation:</emphasis></para>
734 <para>It goes back to the question of readability. If the comment
735 is on the same line as the code it will be harder to read than
736 the comment that is on its own line.</para>
738 <para>There are three exceptions to this rule, which should be
739 violated freely and often: during the definition of variables,

805 <para><emphasis>Explanation:</emphasis></para>
807 <para>A reader of the code should be able to look at the comments
808 just prior to the beginning of a function and discern the
809 reason for its existence and the consequences of using it. The
810 reader should not have to read through the code to determine if
811 a given function is safe for a desired use. The proper
812 information thoroughly presented at the introduction of a
813 function not only saves time for subsequent maintenance or
814 debugging, it more importantly aids in code reuse by allowing a
815 user to determine the safety and applicability of any function
816 for the problem at hand. As a result of such benefits, all

1307 <para>It is easy to write the following code, and a clear argument

1310 <para><emphasis>Example:</emphasis></para>
1312 for ( size_t cnt = 0; cnt < blockListLength(); cnt ++ )
1317 <para><emphasis>Note:</emphasis> Unfortunately, this makes a function call for
1318 each and every iteration. This increases the overhead in the
1319 program, because the compiler has to look up the function each
1320 time, call it, and return a value. Depending on what occurs in
1321 the blockListLength() call, it might even be creating and
1322 destroying structures with each iteration, even though in each
1323 case it is comparing "cnt" to the same value, over and over.
1324 Remember too - even a call to blockListLength() is a function
1325 call, with the same overhead.</para>
1327 <para>Instead of using a function call during the iterations,

1350 <para><emphasis>Explanation:</emphasis></para>
1352 <para>This allows a developer to define a const pointer and call
1353 your function. If your function does not have the const
1354 keyword, we may not be able to use your function. Consider
1355 strcmp, if it were defined as: extern int strcmp( char *s1,

1359 int argc, const char *argv[] ) { strcmp( argv[0], "privoxy"

1363 maintainers do it, we should too.</para>
1369 <sect3 id="s30"><title>Pass and Return by Value</title>
1371 <para><emphasis>Explanation:</emphasis></para>
1373 <para>Most structures cannot fit onto a normal stack entry (i.e.
1374 they are not 4 bytes or less). Aka, a function declaration
1375 like: int load_aclfile( struct client_state csp )</para>

1393 partial path to distinguish their header files from system or
1394 other header files.</para>

1966 <sect1 id="newrelease"><title>Releasing a New Version</title>
1968 When we release versions of <application>Privoxy</application>,
1969 our work leaves our cozy secret lab and has to work in the cold
1970 RealWorld[tm]. Once it is released, there is no way to call it
1971 back, so it is very important that great care is taken to ensure
1972 that everything runs fine, and not to introduce problems in the
1976 So when releasing a new version, please adhere exactly to the
1977 procedure outlined in this chapter.
1981 The following programs are required to follow this process:
1982 <filename>ncftpput</filename> (ncftp), <filename>scp, ssh</filename> (ssh),
1983 <filename>gmake</filename> (GNU's version of make), autoconf, cvs.
1986 <sect2 id="versionnumbers">
1987 <title>Version numbers</title>
1990 First you need to determine which version number the release will have.
1991 <application>Privoxy</application> version numbers consist of three numbers,
1992 separated by dots, like in X.Y.Z, where:
1996 X, the version major, is rarely ever changed. It is increased by one if
1997 turning a development branch into stable substantially changes the functionality,
1998 user interface or configuration syntax. Majors 1 and 2 were
1999 <application>Junkbuster</application>, and 3 will be the first stable
2000 <application>Privoxy</application> release.
2005 Y, the version minor, represents the branch within the major version.
2006 At any point in time, there are two branches being maintained:
2007 The stable branch, with an even minor, say, 2N, in which no functionality is
2008 being added and only bug-fixes are made, and 2N+1, the development branch, in
2009 which the further development of <application>Privoxy</application> takes
2011 This enables us to turn the code upside down and inside out, while at the same time
2012 providing and maintaining a stable version.
2013 The minor is reset to zero (and one) when the major is incremented. When a development
2014 branch has matured to the point where it can be turned into stable, the old stable branch
2015 2N is given up (i.e. no longer maintained), the former development branch 2N+1 becomes the
2016 new stable branch 2N+2, and a new development branch 2N+3 is opened.
2021 Z, the point or sub version, represents a release of the software within a branch.
2022 It is therefore incremented immediately before each code freeze.
2023 In development branches, only the even point versions correspond to actual releases,
2024 while the odd ones denote the evolving state of the sources on CVS in between.
2025 It follows that Z is odd on CVS in development branches most of the time. There, it gets
2026 increased to an even number immediately before a code freeze, and is increased to an odd
2027 number again immediately thereafter.
2028 This ensures that builds from CVS snapshots are easily distinguished from released versions.
2029 The point version is reset to zero when the minor changes.
2037 <sect2 id="beforerelease">
2038 <title>Before the Release: Freeze</title>
2040 The following <emphasis>must be done by one of the
2041 developers</emphasis> prior to each new release.
2047 Make sure that everybody who has worked on the code in the last
2048 couple of days has had a chance to yell <quote>no!</quote> in case
2049 they have pending changes/fixes in their pipelines. Announce the
2050 freeze so that nobody will interfere with last minute changes.
2055 Increment the version number (point from odd to even in development
2056 branches!) in <filename>configure.in</filename>. (RPM spec files
2057 will need to be incremented as well.)
2062 If <filename>default.action</filename> has changed since last
2063 release (i.e. software release or standalone actions file release),
2064 bump up its version info to A.B in this line:
2068 {+add-header{X-Actions-File-Version: A.B} -filter -no-popups}
2072 Then change the version info in doc/webserver/actions/index.php,
2073 line: '$required_actions_file_version = "A.B";'
2078 All documentation should be rebuild after the version bump.
2079 Finished docs should be then be committed to CVS (for those
2080 without the ability to build these). Some docs may require
2081 rather obscure processing tools. <filename>config</filename>,
2082 the man page (and the html version of the man page), and the PDF docs
2083 fall in this category. REAMDE, the man page, AUTHORS, and config
2084 should all also be committed to CVS for other packageers. The
2085 formal docs should be uploaded to the webserver. See the
2086 Section "Updating the webserver" in this manual for details.
2091 All developers should look at the <filename>ChangeLog</filename> and
2092 make sure noteworthy changes are referenced.
2097 <emphasis>Commit all files that were changed in the above steps!</emphasis>
2102 Tag all files in CVS with the version number with
2103 <quote><command>cvs tag v_X_Y_Z</command></quote>.
2104 Don't use vX_Y_Z, ver_X_Y_Z, v_X.Y.Z (won't work) etc.
2109 If the release was in a development branch, increase the point version
2110 from even to odd (X.Y.(Z+1)) again in <filename>configure.in</filename> and
2116 On the webserver, copy the user manual to a new top-level directory
2117 called <filename>X.Y.Z</filename>. This ensures that help links from the CGI
2118 pages, which have the version as a prefix, will go into the right version of the manual.
2119 If this is a development branch release, also symlink <filename>X.Y.(Z-1)</filename>
2120 to <filename>X.Y.Z</filename> and <filename>X.Y.(Z+1)</filename> to
2121 <filename>.</filename> (i.e. dot).

2129 <title>Building and Releasing the Packages</title>
2131 Now the individual packages can be built and released. Note that for
2132 GPL reasons the first package to be released is always the source tarball.
2136 For <emphasis>all</emphasis> types of packages, including the source tarball,
2137 <emphasis>you must make sure that you build from clean sources by exporting
2138 the right version from CVS into an empty directory</emphasis> (just press return when
2139 asked for a password):
2144 mkdir dist # delete or choose different name if it already exists
2146 cvs -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa login
2147 cvs -z3 -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa export -r v_X_Y_Z current
2152 <emphasis>Do NOT change</emphasis> a single bit, including, but not limited to
2153 version information after export from CVS. This is to make sure that
2154 all release packages, and with them, all future bug reports, are based
2155 on exactly the same code.
2159 Please find additional instructions for the source tarball and the
2160 individual platform dependent binary packages below. And details
2161 on the Sourceforge release process below that.
2164 <sect3 id="pack-guidelines">
2165 <title>Note on Privoxy Packaging</title>
2167 Please keep these general guidelines in mind when putting together
2168 your package. These apply to <emphasis>all</emphasis> platforms!
2174 <application>Privoxy</application> <emphasis>requires</emphasis>
2175 write access to: all <filename>*.action</filename> files, all
2176 logfiles, and the <filename>trust</filename> file. You will
2177 need to determine the best way to do this for your platform.
2182 Please include up to date documentation. At a bare minimum:
2186 <filename>LICENSE</filename> (top-level directory)
2191 <filename>README</filename> (top-level directory)
2196 <filename>AUTHORS</filename> (top-level directory)
2201 <filename>man page</filename> (top-level directory, Unix-like
2207 <filename>The User Manual</filename> (doc/webserver/user-manual/)
2212 <filename>FAQ</filename> (doc/webserver/faq/)
2216 Also suggested: <filename>Developer Manual</filename>
2217 (doc/webserver/developer-manual) and <filename>ChangeLog</filename>
2218 (top-level directory). <filename>FAQ</filename> and the manuals are
2219 HTML docs. There are also text versions in
2220 <filename>doc/text/</filename> which could conceivably also be
2224 The documentation has been designed such that the manuals are linked
2225 to each other from parallel directories, and should be packaged
2226 that way. <filename>privoxy-index.html</filename> can also be
2227 included and can serve as a focal point for docs and other links of
2228 interest (and possibly renamed to <filename>index.html</filename>).
2229 This should be one level up from the manuals. There is a link also
2230 on this page to an HTMLized version of the man page. To avoid 404 for
2231 this, it is in CVS as
2232 <filename>doc/webserver/man-page/privoxy-man-page.html</filename>,
2233 and should be included along with the manuals. There is also a
2234 css stylesheets that can be included for better presentation:
2235 <filename>p_doc.css</filename>. This should be in the same directory
2236 with <filename>privoxy-index.html</filename>, (i.e. one level up from
2237 the manual directories).
2242 <filename>user.action</filename> is designed for local preferences.
2243 Make sure this does not get overwritten!
2248 Other configuration files should be installed as the new defaults,
2249 but all previously installed configuration files should be preserved
2250 as backups. This is just good manners :-)
2255 Please check platform specific notes in this doc, if you haven't
2256 done <quote>Privoxy</quote> packaging before for other platform
2257 specific issues. Conversely, please add any notes that you know
2258 are important for your platform (or contact one of the doc
2259 maintainers to do this if you can't).
2264 Packagers should do a <quote>clean</quote> install of their
2265 package after building it. So any previous installs should be
2266 removed first to ensure the integrity of the newly built package.
2267 Then run the package for a while to make sure there are no
2268 obvious problems, before uploading.
2277 <sect3 id="newrelease-tarball"><title>Source Tarball</title>
2279 First, <emphasis>make sure that you have freshly exported the right
2280 version into an empty directory</emphasis>. (See "Building and releasing
2281 packages" above). Then run:
2286 autoheader && autoconf && ./configure
2298 To upload the package to Sourceforge, simply issue
2306 Go to the displayed URL and release the file publicly on Sourceforge.
2307 For the change log field, use the relevant section of the
2308 <filename>ChangeLog</filename> file.
2312 <sect3 id="newrelease-rpm"><title>SuSE, Conectiva or Red Hat RPM</title>
2314 In following text, replace <replaceable class="parameter">dist</replaceable>
2315 with either <quote>rh</quote> for Red Hat or <quote>suse</quote> for SuSE.
2318 First, <emphasis>make sure that you have freshly exported the right

2323 As the only exception to not changing anything after export from CVS,
2324 now examine the file <filename>privoxy-</filename><replaceable class="parameter">dist</replaceable><filename>.spec</filename>
2325 and make sure that the version information and the RPM release number are
2326 correct. The RPM release numbers for each version start at one. Hence it must
2327 be reset to one if this is the first RPM for

2332 release number for that version plus one.
2340 autoheader && autoconf && ./configure

2352 To upload the package to Sourceforge, simply issue
2356 make <replaceable class="parameter">dist</replaceable>-upload <replaceable class="parameter">rpm_packagerev</replaceable>
2360 where <replaceable class="parameter">rpm_packagerev</replaceable> is the
2361 RPM release number as determined above.
2362 Go to the displayed URL and release the file publicly on Sourceforge.
2363 Use the release notes and change log from the source tarball package.
2367 <sect3 id="newrelease-os2"><title>OS/2</title>
2369 First, <emphasis>make sure that you have freshly exported the right
2370 version into an empty directory</emphasis>. (See "Building and releasing
2371 packages" above). Then get the OS/2 Setup module:
2375 cvs -z3 -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa co os2setup
2379 You will need a mix of development tools.
2380 The main compilation takes place with IBM Visual Age C++.
2381 Some ancillary work takes place with GNU tools, available from
2382 various sources like hobbes.nmsu.edu.
2383 Specificially, you will need <filename>autoheader</filename>,
2384 <filename>autoconf</filename> and <filename>sh</filename> tools.
2385 The packaging takes place with WarpIN, available from various sources, including
2386 its home page: <ulink url="http://www.xworkplace.org/">xworkplace</ulink>.
2389 Change directory to the <filename>os2setup</filename> directory.
2390 Edit the os2build.cmd file to set the final executable filename.
2395 installExeName='privoxyos2_setup_X.Y.Z.exe'
2399 Next, edit the <filename>IJB.wis</filename> file so the release number matches
2400 in the <filename>PACKAGEID</filename> section:
2404 PACKAGEID="Privoxy Team\Privoxy\Privoxy Package\X\Y\Z"
2408 You're now ready to build. Run:
2416 You will find the WarpIN-installable executable in the
2417 <filename>./files</filename> directory. Upload this anonymously to
2418 <filename>uploads.sourceforge.net/incoming</filename>, create a release
2419 for it, and you're done. Use the release notes and Change Log from the
2420 source tarball package.
2424 <sect3 id="newrelease-solaris"><title>Solaris</title>
2426 Login to Sourceforge's compilefarm via ssh:
2430 ssh cf.sourceforge.net
2434 Choose the right operating system (not the Debian one).
2435 When logged in, <emphasis>make sure that you have freshly exported the right
2436 version into an empty directory</emphasis>. (See "Building and releasing
2437 packages" above). Then run:
2442 autoheader && autoconf && ./configure
2454 which creates a gzip'ed tar archive. Sadly, you cannot use <command>make
2455 solaris-upload</command> on the Sourceforge machine (no ncftpput). You now have
2456 to manually upload the archive to Sourceforge's ftp server and release
2457 the file publicly. Use the release notes and Change Log from the
2458 source tarball package.
2462 <sect3 id="newrelease-windows"><title>Windows</title>
2464 You should ensure you have the latest version of Cygwin (from
2465 <ulink url="http://www.cygwin.com/">http://www.cygwin.com/</ulink>).
2466 Run the following commands from within a Cygwin bash shell.
2469 First, <emphasis>make sure that you have freshly exported the right
2470 version into an empty directory</emphasis>. (See "Building and releasing
2471 packages" above). Then get the Windows setup module:
2475 cvs -z3 -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa co winsetup
2479 Then you can build the package. This is fully automated, and is
2480 controlled by <filename>winsetup/GNUmakefile</filename>.
2481 All you need to do is:
2490 Now you can manually rename <filename>privoxy_setup.exe</filename> to
2491 <filename>privoxy_setup_X_Y_Z.exe</filename>, and upload it to
2492 SourceForge. When releasing the package on SourceForge, use the release notes
2493 and Change Log from the source tarball package.
2497 <sect3 id="newrelease-debian"><title>Debian</title>
2499 First, <emphasis>make sure that you have freshly exported the
2500 right version into an empty directory</emphasis>. (See
2501 "Building and releasing packages" above). Then add a log
2502 entry to <filename>debian/changelog</filename>, if it is not
2503 already there, for example by running:
2507 debchange -v &p-version;-&p-status;-1 "New upstream version"
2515 dpkg-buildpackage -rfakeroot -us -uc -b
2520 <filename>../privoxy_&p-version;-&p-status;-1_i386.deb</filename>
2521 which can be uploaded. To upload the package to Sourceforge, simply
2531 <sect3 id="newrelease-macosx"><title>Mac OSX</title>
2533 First, <emphasis>make sure that you have freshly exported the right
2534 version into an empty directory</emphasis>. (See "Building and releasing
2535 packages" above). Then get the Mac OSX setup module:
2539 cvs -z3 -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa co osxsetup
2552 This will run <filename>autoheader</filename>, <filename>autoconf</filename> and

2558 Bring up PackageMaker with the PrivoxyPackage.pmsp definition file, modify the package
2559 name to match the release, and hit the "Create package" button.
2560 If you specify ./Privoxy.pkg as the output package name, you can then create
2561 the distributable zip file with the command:
2565 zip -r privoxyosx_setup_x.y.z.zip Privoxy.pkg
2569 You can then upload <filename>privoxyosx_setup_x.y.z.zip</filename> anonymously to
2570 <filename>uploads.sourceforge.net/incoming</filename>,
2571 create a release for it, and you're done. Use the release notes

2760 <sect1 id="webserver-update"><title>Update the Webserver</title>
2762 When updating the webserver, please follow these steps to make
2763 sure that no broken links, inconsistent contents or permission
2764 problems will occur:
2767 If you have changed anything in the stable-branch documentation source
2772 make dok dok-pdf # (or 'make redhat-dok dok-pdf' if 'make dok' doesn't work for you)
2776 That will generate <filename>doc/webserver/user-manual</filename>,
2777 <filename>doc/webserver/developer-manual</filename>,
2778 <filename>doc/webserver/faq</filename>,
2779 <filename>doc/pdf/*.pdf</filename> and
2780 <filename>doc/webserver/index.html</filename> automatically.
2783 If you changed the manual page sources, generate
2784 <filename>doc/webserver/man-page/privoxy-man-page.html</filename>
2785 by running <quote><command>make man</command></quote>. (This is
2786 a separate target due to dependencies on some obscure perl scripts
2787 [now in CVS, but not well tested]. See comments in <filename>GNUmakefile</filename>.)
2790 If you want to add new files to the webserver, create them locally in
2791 the <filename>doc/webserver/*</filename> directory (or
2792 create new directories under <filename>doc/webserver</filename>).
2795 Next, commit any changes from the above steps to CVS. All set?
2796 If these are docs in the stable branch, then do:
2804 This will do the upload to <ulink url="http://www.privoxy.org/">the
2805 webserver</ulink> (www.privoxy.org) and ensure all files and directories
2806 there are group writable.
2809 Please do <emphasis>NOT</emphasis> use any other means of transferring
2810 files to the webserver to avoid permission problems. Also, please do not
2811 upload docs from development branches or versions. The publicly posted
2812 docs should be in sync with the last official release.
