-2. Quickstart to Junkbuster Development
+ Privoxy, as an heir to Junkbuster, is a Free Software project and the code
+ is licensed under the GPL. As such, Privoxy development is potentially
+ open to anyone who has the time, knowledge, and desire to contribute in
+ any capacity. Our goals are simply to continue the mission, to improve
+ Privoxy, and to make it available to as wide an audience as possible.
+
+ One does not have to be a programmer to contribute. Packaging, testing,
+ documenting and porting, are all important jobs as well.
+
+ --------------------------------------------------------------------------
+
+ 1.1. Quickstart to Privoxy Development
+
+ The first step is to join the developer's mailing list. You can submit
+ your ideas, or even better patches. Patches are best submitted to the
+ Sourceforge tracker set up for this purpose, but can be sent to the list
+ for review too.
+
+ You will also need to have a cvs package installed, which will entail
+ having ssh installed as well (which seems to be a requirement of
+ SourceForge), in order to access the cvs repository. Having the GNU build
+ tools is also going to be important (particularly, autoconf and gmake).
+
+ For the time being (read, this section is under construction), you can
+ also refer to the extensive comments in the source code. In fact, reading
+ the code is recommended in any case.
+
+ --------------------------------------------------------------------------
+
+2. The CVS Repository
+
+ If you become part of the active development team, you will eventually
+ need write access to our holy grail, the CVS repository. One of the team
+ members will need to set this up for you. Please read this chapter
+ completely before accessing via CVS.
+
+ --------------------------------------------------------------------------
+
+ 2.1. Access to CVS
+
+ The project's CVS repository is hosted on SourceForge. Please refer to the
+ chapters 6 and 7 in SF's site documentation for the technical access
+ details for your operating system. For historical reasons, the CVS server
+ is called ijbswa.cvs.sourceforge.net, the repository is called ijbswa, and
+ the source tree module is called current.
+
+ --------------------------------------------------------------------------
+
+ 2.2. Branches
+
+ Within the CVS repository, there are modules and branches. As mentioned,
+ the sources are in the current "module". Other modules are present for
+ platform specific issues. There is a webview of the CVS hierarchy at
+ http://ijbswa.cvs.sourceforge.net/ijbswa/, which might help with
+ visualizing how these pieces fit together.
+
+ Branches are used to fork a sub-development path from the main trunk.
+ Within the current module where the sources are, there is always at least
+ one "branch" from the main trunk devoted to a stable release series. The
+ main trunk is where active development takes place for the next stable
+ series (e.g. 3.2.x). So just prior to each stable series (e.g. 3.0.x), a
+ branch is created just for stable series releases (e.g. 3.0.0 -> 3.0.1 ->
+ 3.0.2, etc). Once the initial stable release of any stable branch has
+ taken place, this branch is only used for bugfixes, which have had prior
+ testing before being committed to CVS. (See Version Numbers below for
+ details on versioning.)
+
+ At one time there were two distinct branches: stable and unstable. The
+ more drastic changes were to be in the unstable branch. These branches
+ have now been merged to minimize time and effort of maintaining two
+ branches.
+
+ --------------------------------------------------------------------------
+
+ 2.3. CVS Commit Guidelines
+
+ The source tree is the heart of every software project. Every effort must
+ be made to ensure that it is readable, compilable and consistent at all
+ times. There are differing guidelines for the stable branch and the main
+ development trunk, and we ask anyone with CVS access to strictly adhere to
+ the following guidelines:
+
+ Basic Guidelines, for all branches:
+
+ * Please don't commit even a small change without testing it thoroughly
+ first. When we're close to a public release, ask a fellow developer to
+ review your changes.
+
+ * Your commit message should give a concise overview of what you changed
+ (no big details) and why you changed it Just check previous messages
+ for good examples.
+
+ * Don't use the same message on multiple files, unless it equally
+ applies to all those files.
+
+ * If your changes span multiple files, and the code won't recompile
+ unless all changes are committed (e.g. when changing the signature of
+ a function), then commit all files one after another, without long
+ delays in between. If necessary, prepare the commit messages in
+ advance.
+
+ * Before changing things on CVS, make sure that your changes are in line
+ with the team's general consensus on what should be done.
+
+ * Note that near a major public release, we get more cautious. There is
+ always the possibility to submit a patch to the patch tracker instead.

3. Documentation Guidelines
- All docs are in SGML format and located in the doc/source directory.
-
- How do you update the webserver (i.e. the pages on sourceforge)?
-
- 1. Run make dok (which uses the documents in doc/source to update all
- text files in doc/text and to update all web documents in
- doc/webserver.
- 2. Run make webserver which copies all files from doc/webserver to
- the sourceforge webserver via scp.
- _________________________________________________________________
-
+ All formal documents are maintained in Docbook SGML and located in the
+ doc/source/* directory. You will need Docbook, the Docbook DTD's and the
+ Docbook modular stylesheets (or comparable alternatives), and either jade
+ or openjade (recommended) installed in order to build docs from source.
+ Currently there is user-manual, FAQ, and, of course this, the
+ developer-manual in this format. The README, AUTHORS, INSTALL, privoxy.1
+ (man page), and config files are also now maintained as Docbook SGML.
+ These files, when built, in the top-level source directory are generated
+ files! Also, the Privoxy index.html (and a variation on this file,
+ privoxy-index.html, meant for inclusion with doc packages), are maintained
+ as SGML as well. DO NOT edit these directly. Edit the SGML source, or
+ contact someone involved in the documentation.
+
+ config requires some special handling. The reason it is maintained this
+ way is so that the extensive comments in the file mirror those in
+ user-manual. But the conversion process requires going from SGML to HTML
+ to text to special formatting required for the embedded comments. Some of
+ this does not survive so well. Especially some of the examples that are
+ longer than 80 characters. The build process for this file outputs to
+ config.new, which should be reviewed for errors and mis-formatting. Once
+ satisfied that it is correct, then it should be hand copied to config.
+
+ Other, less formal documents (e.g. LICENSE) are maintained as plain text
+ files in the top-level source directory.
+
+ Packagers are encouraged to include this documentation. For those without
+ the ability to build the docs locally, text versions of each are kept in
+ CVS. HTML versions are also being kept in CVS under doc/webserver/*. And
+ PDF version are kept in doc/pdf/*.
+
+ Formal documents are built with the Makefile targets of make dok, or
+ alternately make redhat-dok. If you have problems, try both. The build
+ process uses the document SGML sources in doc/source/*/* to update all
+ text files in doc/text/ and to update all HTML documents in
+ doc/webserver/.
+
+ Documentation writers should please make sure documents build successfully
+ before committing to CVS, if possible.
+
+ How do you update the webserver (i.e. the pages on privoxy.org)?
+
+ 1. First, build the docs by running make dok (or alternately make
+ redhat-dok). For PDF docs, do make dok-pdf.
+
+ 2. Run make webserver which copies all files from doc/webserver to the
+ sourceforge webserver via scp.
+
+ Finished docs should be occasionally submitted to CVS
+ (doc/webserver/*/*.html) so that those without the ability to build them
+ locally, have access to them if needed. This is especially important just
+ prior to a new release! Please do this after the $VERSION and other
+ release specific data in configure.in has been updated (this is done just
+ prior to a new release).
+
+ --------------------------------------------------------------------------
+
+ 3.1. Quickstart to Docbook and SGML
+
+ If you are not familiar with SGML, it is a markup language similar to
+ HTML. Actually, not a mark up language per se, but a language used to
+ define markup languages. In fact, HTML is an SGML application. Both will
+ use "tags" to format text and other content. SGML tags can be much more
+ varied, and flexible, but do much of the same kinds of things. The tags,
+ or "elements", are definable in SGML. There is no set "standards". Since
+ we are using Docbook, our tags are those that are defined by Docbook. Much
+ of how the finish document is rendered is determined by the "stylesheets".
+ The stylesheets determine how each tag gets translated to HTML, or other
+ formats.
+
+ Tags in Docbook SGML need to be always "closed". If not, you will likely
+ generate errors. Example: <title>My Title</title>. They are also
+ case-insensitive, but we strongly suggest using all lower case. This keeps
+ compatibility with [Docbook] XML.
+
+ Our documents use "sections" for the most part. Sections will be processed
+ into HTML headers (e.g. h1 for sect1). The Docbook stylesheets will use
+ these to also generate the Table of Contents for each doc. Our TOC's are
+ set to a depth of three. Meaning sect1, sect2, and sect3 will have TOC
+ entries, but sect4 will not. Each section requires a <title> element, and
+ at least one <para>. There is a limit of five section levels in Docbook,
+ but generally three should be sufficient for our purposes.
+
+ Some common elements that you likely will use:
+
+ <para></para>, paragraph delimiter. Most text needs to be within paragraph
+ elements (there are some exceptions).
+ <emphasis></emphasis>, the stylesheets make this italics.
+ <filename></filename>, files and directories.
+ <command></command>, command examples.
+ <literallayout></literallayout>, like <pre>, more or less.
+ <itemizedlist></itemizedlist>, list with bullets.
+ <listitem></listitem>, member of the above.
+ <screen></screen>, screen output, implies <literallayout>.
+ <ulink url="example.com"></ulink>, like HTML <a> tag.
+ <quote></quote>, for, doh, quoting text.
+
+ Look at any of the existing docs for examples of all these and more.
+
+ You might also find "Writing Documentation Using DocBook - A Crash Course"
+ useful.
+
+ --------------------------------------------------------------------------
+
+ 3.2. Privoxy Documentation Style
+
+ It will be easier if everyone follows a similar writing style. This just
+ makes it easier to read what someone else has written if it is all done in
+ a similar fashion.
+
+ Here it is:
+
+ * All tags should be lower case.
+
+ * Tags delimiting a block of text (even small blocks) should be on their
+ own line. Like:
+
+ <para>
+ Some text goes here.
+ </para>
+
+
+ Tags marking individual words, or few words, should be in-line:
+
+ Just to <emphasis>emphasize</emphasis>, some text goes here.
+
+
+ * Tags should be nested and step indented for block text like: (except
+ in-line tags)
+
+ <para>
+ <itemizedlist>
+ <para>
+ <listitem>
+ Some text goes here in our list example.
+ </listitem>
+ </para>
+ </itemizedlist>
+ </para>
+
+
+ This makes it easier to find the text amongst the tags ;-)
+ * Use white space to separate logical divisions within a document, like
+ between sections. Running everything together consistently makes it
+ harder to read and work on.
+
+ * Do not hesitate to make comments. Comments can either use the
+ <comment> element, or the <!-- --> style comment familiar from HTML.
+ (Note in Docbook v4.x <comment> is replaced by <remark>.)
+
+ * We have an international audience. Refrain from slang, or English
+ idiosyncrasies (too many to list :). Humor also does not translate
+ well sometimes.
+
+ * Try to keep overall line lengths in source files to 80 characters or
+ less for obvious reasons. This is not always possible, with lengthy
+ URLs for instance.
+
+ * Our documents are available in differing formats. Right now, they are
+ just plain text, HTML, and PDF, but others are always a future
+ possibility. Be careful with URLs (<ulink>), and avoid this mistake:
+
+ My favorite site is <ulink url="http://example.com">here</ulink>.
+
+ This will render as "My favorite site is here", which is not real
+ helpful in a text doc. Better like this:
+
+ My favorite site is <ulink
+ url="http://example.com">example.com</ulink>.
+
+ * All documents should be spell checked occasionally. aspell can check
+ SGML with the -H option. (ispell I think too.)
+
+ --------------------------------------------------------------------------
+
+ 3.3. Privoxy Custom Entities
+
+ Privoxy documentation is using a number of customized "entities" to
+ facilitate documentation maintenance.
+
+ We are using a set of "boilerplate" files with generic text, that is used
+ by multiple docs. This way we can write something once, and use it
+ repeatedly without having to re-write the same content over and over
+ again. If editing such a file, keep in mind that it should be generic.
+ That is the purpose; so it can be used in varying contexts without
+ additional modifications.
+
+ We are also using what Docbook calls "internal entities". These are like
+ variables in programming. Well, sort of. For instance, we have the
+ p-version entity that contains the current Privoxy version string. You are
+ strongly encouraged to use these where possible. Some of these obviously
+ require re-setting with each release (done by the Makefile). A sampling of
+ custom entities are listed below. See any of the main docs for examples.
+
+ * Re- "boilerplate" text entities are defined like:
+
+ <!entity supported SYSTEM "supported.sgml">
+
+ In this example, the contents of the file, supported.sgml is available
+ for inclusion anywhere in the doc. To make this happen, just reference
+ the now defined entity: &supported; (starts with an ampersand and ends
+ with a semi-colon), and the contents will be dumped into the finished
+ doc at that point.
+
+ * Commonly used "internal entities":
+
+ p-version: the Privoxy version string, e.g. "3.0.8".
+ p-status: the project status, either "alpha", "beta", or "stable".
+ p-not-stable: use to conditionally include text in "not stable"
+ releases (e.g. "beta").
+ p-stable: just the opposite.
+ p-text: this doc is only generated as text.
+
+ There are others in various places that are defined for a specific
+ purpose. Read the source!

Explanation:
-
- Comment as much as possible without commenting the obvious. For
- example do not comment "aVariable is equal to bVariable". Instead
- explain why aVariable should be equal to the bVariable. Just because a
- person can read code does not mean they will understand why or what is
- being done. A reader may spend a lot more time figuring out what is
- going on when a simple comment or explanation would have prevented the
- extra research. Please help your brother IJB'ers out!

- The comments will also help justify the intent of the code. If the

Explanation:

- existence and the consequences of using it. The reader should not have
- to read through the code to determine if a given function is safe for

- introduction of a function not only saves time for subsequent
- maintenance or debugging, it more importantly aids in code reuse by
- allowing a user to determine the safety and applicability of any
- function for the problem at hand. As a result of such benefits, all
- functions should contain the information presented in the addendum

Explanation:
-
- Each closing brace should be followed on the same line by a comment
- that describes the origination of the brace if the original brace is
- off of the screen, or otherwise far away from the closing brace. This
- will simplify the debugging, maintenance, and readability of the code.

Note: Unfortunately, this makes a function call for each and every

compiler has to look up the function each time, call it, and return a

Explanation:
-
- This allows a developer to define a const pointer and call your

+
I could then not use it to compare argv's in main: int main( int argc,

+ --------------------------------------------------------------------------
+
+ 4.7.2. Provide a default case for all switch statements
Explanation:
-
- What you think is guaranteed is never really guaranteed. The value
- that you don't think you need to check is the one that someday will be
- passed. So, to protect yourself from the unknown, always have a
- default step in a switch statement.

+ What you think is guaranteed is never really guaranteed. The value that
+ you don't think you need to check is the one that someday will be passed.
+ So, to protect yourself from the unknown, always have a default step in a

Example:

-{
- case hash_actions_file :
- ... code ...
- break;
-
- case hash_confdir :
- ... code ...
- break;
-
- default :
- log_error( ... );
- ... anomly code goes here ...
- continue; / break; / exit( 1 ); / etc ...
-
-} /* end switch( hash_string( cmd ) ) */
-
- Note: If you already have a default condition, you are obviously
- exempt from this point. Of note, most of the WIN32 code calls
- `DefWindowProc' after the switch statement. This API call *should* be
- included in a default statement.
-
+

+
Another Note: This is not so much a readability issue as a robust
- programming issue. The "anomly code goes here" may be no more than a
+ programming issue. The "anomaly code goes here" may be no more than a
print to the STDERR stream (as in load_config). Or it may really be an

+
+ 4.7.3. Try to avoid falling through cases in a switch statement.
Explanation:
-
- In general, you will want to have a 'break' statement within each
- 'case' of a switch statement. This allows for the code to be more
- readable and understandable, and furthermore can prevent unwanted
- surprises if someone else later gets creative and moves the code
- around.
-
- The language allows you to plan the fall through from one case
- statement to another simply by omitting the break statement within the
- case statement. This feature does have benefits, but should only be
- used in rare cases. In general, use a break statement for each case
- statement.
-
- If you choose to allow fall through, you should comment both the fact
- of the fall through and reason why you felt it was necessary.
- _________________________________________________________________

Explanation:
-
+
On 32-bit platforms, int usually has the range of long. On 16-bit
platforms, int has the range of short.
-
+
Status: open-to-debate. In the case of most FSF projects (including
- X/GNU-Emacs), there are typedefs to int4, int8, int16, (or equivalence

+
+ 4.7.5. Don't mix size_t and other types
Explanation:
-
- The type of size_t varies across platforms. Do not make assumptions
- about whether it is signed or unsigned, or about how long it is. Do
- not compare a size_t against another variable of a different type (or
- even against a constant) without casting one of the values. Try to
- avoid using size_t if you can.

Instead of:

- Explanation: - there is more room for comments on the individual
- variables - easier to add new variables without messing up the
- original ones - when searching on a variable to find its type, there
- is less clutter to "visually" eliminate

Explanation:
-
- If you have to "malloc" an instance, you are responsible for insuring

- within some other programmer's code. You are also responsible for
- ensuring that deletion is timely (i.e. not too soon, not too late).
- This is known as "low-coupling" and is a "good thing (tm)". You may

+
+ * Select group: the version of Privoxy that we are about to release.
+
+ * Fill the Summary and Detailed Description with something intelligent
+ (keep it short and precise).
+
+ Do not mail to the mailing list (we cannot keep track on issues there).
+
+ --------------------------------------------------------------------------
+
+6. Releasing a New Version
+
+ When we release versions of Privoxy, our work leaves our cozy secret lab
+ and has to work in the cold RealWorld[tm]. Once it is released, there is
+ no way to call it back, so it is very important that great care is taken
+ to ensure that everything runs fine, and not to introduce problems in the
+ very last minute.
+
+ So when releasing a new version, please adhere exactly to the procedure
+ outlined in this chapter.
+
+ The following programs are required to follow this process: ncftpput
+ (ncftp), scp, ssh (ssh), gmake (GNU's version of make), autoconf, cvs.
+
+ --------------------------------------------------------------------------
+
+ 6.1. Version numbers
+
+ First you need to determine which version number the release will have.
+ Privoxy version numbers consist of three numbers, separated by dots, like
+ in X.Y.Z (e.g. 3.0.0), where:
+
+ * X, the version major, is rarely ever changed. It is increased by one
+ if turning a development branch into stable substantially changes the
+ functionality, user interface or configuration syntax. Majors 1 and 2
+ were Junkbuster, and 3 will be the first stable Privoxy release.
+
+ * Y, the version minor, represents the branch within the major version.
+ At any point in time, there are two branches being maintained: The
+ stable branch, with an even minor, say, 2N, in which no functionality
+ is being added and only bug-fixes are made, and 2N+1, the development
+ branch, in which the further development of Privoxy takes place. This
+ enables us to turn the code upside down and inside out, while at the
+ same time providing and maintaining a stable version. The minor is
+ reset to zero (and one) when the major is incremented. When a
+ development branch has matured to the point where it can be turned
+ into stable, the old stable branch 2N is given up (i.e. no longer
+ maintained), the former development branch 2N+1 becomes the new stable
+ branch 2N+2, and a new development branch 2N+3 is opened.
+
+ * Z, the point or sub version, represents a release of the software
+ within a branch. It is therefore incremented immediately before each
+ code freeze. In development branches, only the even point versions
+ correspond to actual releases, while the odd ones denote the evolving
+ state of the sources on CVS in between. It follows that Z is odd on
+ CVS in development branches most of the time. There, it gets increased
+ to an even number immediately before a code freeze, and is increased
+ to an odd number again immediately thereafter. This ensures that
+ builds from CVS snapshots are easily distinguished from released
+ versions. The point version is reset to zero when the minor changes.
+
+ Stable branches work a little differently, since there should be
+ little to no development happening in such branches. Remember, only
+ bugfixes, which presumably should have had some testing before being
+ committed. Stable branches will then have their version reported as
+ 0.0.0, during that period between releases when changes are being
+ added. This is to denote that this code is not for release. Then as
+ the release nears, the version is bumped according: e.g. 3.0.1 ->
+ 0.0.0 -> 3.0.2.
+
+ In summary, the main CVS trunk is the development branch where new
+ features are being worked on for the next stable series. This should
+ almost always be where the most activity takes place. There is always at
+ least one stable branch from the trunk, e.g now it is 3.0, which is only
+ used to release stable versions. Once the initial *.0 release of the
+ stable branch has been done, then as a rule, only bugfixes that have had
+ prior testing should be committed to the stable branch. Once there are
+ enough bugfixes to justify a new release, the version of this branch is
+ again incremented Example: 3.0.0 -> 3.0.1 -> 3.0.2, etc are all stable
+ releases from within the stable branch. 3.1.x is currently the main trunk,
+ and where work on 3.2.x is taking place. If any questions, please post to
+ the devel list before committing to a stable branch!
+
+ Developers should remember too that if they commit a bugfix to the stable
+ branch, this will more than likely require a separate submission to the
+ main trunk, since these are separate development trees within CVS. If you
+ are working on both, then this would require at least two separate check
+ outs (i.e main trunk, and the stable release branch, which is v_3_0_branch
+ at the moment).
+
+ --------------------------------------------------------------------------
+
+ 6.2. Before the Release: Freeze
+
+ The following must be done by one of the developers prior to each new
+ release.
+
+ * Make sure that everybody who has worked on the code in the last couple
+ of days has had a chance to yell "no!" in case they have pending
+ changes/fixes in their pipelines. Announce the freeze so that nobody
+ will interfere with last minute changes.
+
+ * Increment the version number (point from odd to even in development
+ branches!) in configure.in. (RPM spec files will need to be
+ incremented as well.)
+
+ * If default.action has changed since last release (i.e. software
+ release or standalone actions file release), bump up its version info
+ to A.B in this line:
+
+ {+add-header{X-Actions-File-Version: A.B} -filter -no-popups}
+
+ Then change the version info in doc/webserver/actions/index.php, line:
+ '$required_actions_file_version = "A.B";'
+
+ * All documentation should be rebuild after the version bump. Finished
+ docs should be then be committed to CVS (for those without the ability
+ to build these). Some docs may require rather obscure processing
+ tools. config, the man page (and the html version of the man page),
+ and the PDF docs fall in this category. REAMDE, the man page, AUTHORS,
+ and config should all also be committed to CVS for other packagers.
+ The formal docs should be uploaded to the webserver. See the Section
+ "Updating the webserver" in this manual for details.
+
+ * The User Manual is also used for context sensitive help for the CGI
+ editor. This is version sensitive, so that the user will get
+ appropriate help for his/her release. So with each release a fresh
+ version should be uploaded to the webserver (this is in addition to
+ the main User Manual link from the main page since we need to keep
+ manuals for various versions available). The CGI pages will link to
+ something like http://privoxy.org/$(VERSION)/user-manual/. This will
+ need to be updated for each new release. There is no Makefile target
+ for this at this time!!! It needs to be done manually.
+
+ * All developers should look at the ChangeLog and make sure noteworthy
+ changes are referenced.
+
+ * Commit all files that were changed in the above steps!
+
+ * Tag all files in CVS with the version number with "cvs tag v_X_Y_Z".
+ Don't use vX_Y_Z, ver_X_Y_Z, v_X.Y.Z (won't work) etc.
+
+ * If the release was in a development branch, increase the point version
+ from even to odd (X.Y.(Z+1)) again in configure.in and commit your
+ change.
+
+ * On the webserver, copy the user manual to a new top-level directory
+ called X.Y.Z. This ensures that help links from the CGI pages, which
+ have the version as a prefix, will go into the right version of the
+ manual. If this is a development branch release, also symlink
+ X.Y.(Z-1) to X.Y.Z and X.Y.(Z+1) to . (i.e. dot).
+
+ --------------------------------------------------------------------------
+
+ 6.3. Building and Releasing the Packages
+
+ Now the individual packages can be built and released. Note that for GPL
+ reasons the first package to be released is always the source tarball.
+
+ For all types of packages, including the source tarball, you must make
+ sure that you build from clean sources by exporting the right version from
+ CVS into an empty directory (just press return when asked for a password):
+
+ mkdir dist # delete or choose different name if it already exists
+ cd dist
+ cvs -d:pserver:anonymous@ijbswa.cvs.sourceforge.net:/cvsroot/ijbswa login
+ cvs -z3 -d:pserver:anonymous@ijbswa.cvs.sourceforge.net:/cvsroot/ijbswa export -r v_X_Y_Z current
+
+ Do NOT change a single bit, including, but not limited to version
+ information after export from CVS. This is to make sure that all release
+ packages, and with them, all future bug reports, are based on exactly the
+ same code.
+
+ +------------------------------------------------------------------------+
+ | Warning |
+ |------------------------------------------------------------------------|
+ | Every significant release of Privoxy has included at least one package |
+ | that either had incorrect versions of files, missing files, or |
+ | incidental leftovers from a previous build process that gave unknown |
+ | numbers of users headaches to try to figure out what was wrong. |
+ | PLEASE, make sure you are using pristene sources, and are following |
+ | the prescribed process! |
+ +------------------------------------------------------------------------+
+
+ Please find additional instructions for the source tarball and the
+ individual platform dependent binary packages below. And details on the
+ Sourceforge release process below that.
+
+ --------------------------------------------------------------------------
+
+ 6.3.1. Note on Privoxy Packaging
+
+ Please keep these general guidelines in mind when putting together your
+ package. These apply to all platforms!
+
+ * Privoxy requires write access to: all *.action files, all logfiles,
+ and the trust file. You will need to determine the best way to do this
+ for your platform.
+
+ * Please include up to date documentation. At a bare minimum:
+
+ LICENSE (top-level directory)
+
+ README (top-level directory)
+
+ AUTHORS (top-level directory)
+
+ man page (top-level directory, Unix-like platforms only)
+
+ The User Manual (doc/webserver/user-manual/)
+
+ FAQ (doc/webserver/faq/)
+
+ Also suggested: Developer Manual (doc/webserver/developer-manual) and
+ ChangeLog (top-level directory). FAQ and the manuals are HTML docs.
+ There are also text versions in doc/text/ which could conceivably also
+ be included.
+
+ The documentation has been designed such that the manuals are linked
+ to each other from parallel directories, and should be packaged that
+ way. privoxy-index.html can also be included and can serve as a focal
+ point for docs and other links of interest (and possibly renamed to
+ index.html). This should be one level up from the manuals. There is a
+ link also on this page to an HTMLized version of the man page. To
+ avoid 404 for this, it is in CVS as
+ doc/webserver/man-page/privoxy-man-page.html, and should be included
+ along with the manuals. There is also a css stylesheets that can be
+ included for better presentation: p_doc.css. This should be in the
+ same directory with privoxy-index.html, (i.e. one level up from the
+ manual directories).
+
+ * user.action and user.filter are designed for local preferences. Make
+ sure these do not get overwritten! config should not be overwritten
+ either. This has especially important configuration data in it. trust
+ should be left in tact as well.
+
+ * Other configuration files (default.action, default.filter and
+ standard.action) should be installed as the new defaults, but all
+ previously installed configuration files should be preserved as
+ backups. This is just good manners :-) These files are likely to
+ change between releases and contain important new features and bug
+ fixes.
+
+ * Please check platform specific notes in this doc, if you haven't done
+ "Privoxy" packaging before for other platform specific issues.
+ Conversely, please add any notes that you know are important for your
+ platform (or contact one of the doc maintainers to do this if you
+ can't).
+
+ * Packagers should do a "clean" install of their package after building
+ it. So any previous installs should be removed first to ensure the
+ integrity of the newly built package. Then run the package for a while
+ to make sure there are no obvious problems, before uploading.
+
+ --------------------------------------------------------------------------
+
+ 6.3.2. Source Tarball
+
+ First, make sure that you have freshly exported the right version into an
+ empty directory. (See "Building and releasing packages" above). Then run:
+
+ cd current
+ autoheader && autoconf && ./configure
+
+ Then do:
+
+ make tarball-dist
+
+ To upload the package to Sourceforge, simply issue
+
+ make tarball-upload
+
+ Go to the displayed URL and release the file publicly on Sourceforge. For
+ the change log field, use the relevant section of the ChangeLog file.
+
+ --------------------------------------------------------------------------
+
+ 6.3.3. SuSE, Conectiva or Red Hat RPM
+
+ In following text, replace dist with either "rh" for Red Hat or "suse" for
+ SuSE.
+
+ First, make sure that you have freshly exported the right version into an
+ empty directory. (See "Building and releasing packages" above).
+
+ As the only exception to not changing anything after export from CVS, now
+ examine the file privoxy-dist.spec and make sure that the version
+ information and the RPM release number are correct. The RPM release
+ numbers for each version start at one. Hence it must be reset to one if
+ this is the first RPM for dist which is built from version X.Y.Z. Check
+ the file list if unsure. Else, it must be set to the highest already
+ available RPM release number for that version plus one.
+
+ Then run:
+
+ cd current
+ autoheader && autoconf && ./configure
+
+ Then do
+
+ make dist-dist
+
+ To upload the package to Sourceforge, simply issue
+
+ make dist-upload rpm_packagerev
+
+ where rpm_packagerev is the RPM release number as determined above. Go to
+ the displayed URL and release the file publicly on Sourceforge. Use the
+ release notes and change log from the source tarball package.
+
+ --------------------------------------------------------------------------
+
+ 6.3.4. OS/2
+
+ First, make sure that you have freshly exported the right version into an
+ empty directory. (See "Building and releasing packages" above). Then get
+ the OS/2 Setup module:
+
+ cvs -z3 -d:pserver:anonymous@ijbswa.cvs.sourceforge.net:/cvsroot/ijbswa co os2setup
+
+ You will need a mix of development tools. The main compilation takes place
+ with IBM Visual Age C++. Some ancillary work takes place with GNU tools,
+ available from various sources like hobbes.nmsu.edu. Specificially, you
+ will need autoheader, autoconf and sh tools. The packaging takes place
+ with WarpIN, available from various sources, including its home page:
+ xworkplace.
+
+ Change directory to the os2setup directory. Edit the os2build.cmd file to
+ set the final executable filename. For example,
+
+ installExeName='privoxyos2_setup_X.Y.Z.exe'
+
+ Next, edit the IJB.wis file so the release number matches in the PACKAGEID
+ section:
+
+ PACKAGEID="Privoxy Team\Privoxy\Privoxy Package\X\Y\Z"
+
+ You're now ready to build. Run:
+
+ os2build
+
+ You will find the WarpIN-installable executable in the ./files directory.
+ Upload this anonymously to uploads.sourceforge.net/incoming, create a
+ release for it, and you're done. Use the release notes and Change Log from
+ the source tarball package.
+
+ --------------------------------------------------------------------------
+
+ 6.3.5. Solaris
+
+ Login to Sourceforge's compilefarm via ssh:
+
+ ssh cf.sourceforge.net
+
+ Choose the right operating system (not the Debian one). When logged in,
+ make sure that you have freshly exported the right version into an empty
+ directory. (See "Building and releasing packages" above). Then run:
+
+ cd current
+ autoheader && autoconf && ./configure
+
+ Then run
+
+ gmake solaris-dist
+
+ which creates a gzip'ed tar archive. Sadly, you cannot use make
+ solaris-upload on the Sourceforge machine (no ncftpput). You now have to
+ manually upload the archive to Sourceforge's ftp server and release the
+ file publicly. Use the release notes and Change Log from the source
+ tarball package.
+
+ --------------------------------------------------------------------------
+
+ 6.3.6. Windows
+
+ You should ensure you have the latest version of Cygwin (from
+ http://www.cygwin.com/). Run the following commands from within a Cygwin
+ bash shell.
+
+ First, make sure that you have freshly exported the right version into an
+ empty directory. (See "Building and releasing packages" above). Then get
+ the Windows setup module:
+
+ cvs -z3 -d:pserver:anonymous@ijbswa.cvs.sourceforge.net:/cvsroot/ijbswa co winsetup
+
+ Then you can build the package. This is fully automated, and is controlled
+ by winsetup/GNUmakefile. All you need to do is:
+
+ cd winsetup
+ make
+
+ Now you can manually rename privoxy_setup.exe to privoxy_setup_X_Y_Z.exe,
+ and upload it to SourceForge. When releasing the package on SourceForge,
+ use the release notes and Change Log from the source tarball package.
+
+ --------------------------------------------------------------------------
+
+ 6.3.7. Debian
+
+ First, make sure that you have freshly exported the right version into an
+ empty directory. (See "Building and releasing packages" above). Then add a
+ log entry to debian/changelog, if it is not already there, for example by
+ running:
+
+ debchange -v 3.0.8-stable-1 "New upstream version"
+
+ Then, run:
+
+ dpkg-buildpackage -rfakeroot -us -uc -b
+
+ This will create ../privoxy_3.0.8-stable-1_i386.deb which can be uploaded.
+ To upload the package to Sourceforge, simply issue
+
+ make debian-upload
+
+ --------------------------------------------------------------------------
+
+ 6.3.8. Mac OSX
+
+ First, make sure that you have freshly exported the right version into an
+ empty directory. (See "Building and releasing packages" above). Then get
+ the Mac OSX setup module:
+
+ cvs -z3 -d:pserver:anonymous@ijbswa.cvs.sourceforge.net:/cvsroot/ijbswa co osxsetup
+
+ Then run:
+
+ cd osxsetup
+ build
+
+ This will run autoheader, autoconf and configure as well as make. Finally,
+ it will copy over the necessary files to the ./osxsetup/files directory
+ for further processing by PackageMaker.
+
+ Bring up PackageMaker with the PrivoxyPackage.pmsp definition file, modify
+ the package name to match the release, and hit the "Create package"
+ button. If you specify ./Privoxy.pkg as the output package name, you can
+ then create the distributable zip file with the command:
+
+ zip -r privoxyosx_setup_x.y.z.zip Privoxy.pkg
+
+ You can then upload privoxyosx_setup_x.y.z.zip anonymously to
+ uploads.sourceforge.net/incoming, create a release for it, and you're
+ done. Use the release notes and Change Log from the source tarball
+ package.
+
+ --------------------------------------------------------------------------
+
+ 6.3.9. FreeBSD
+
+ Login to Sourceforge's compile-farm via ssh:
+
+ ssh cf.sourceforge.net
+
+ Choose the right operating system. When logged in, make sure that you have
+ freshly exported the right version into an empty directory. (See "Building
+ and releasing packages" above). Then run:
+
+ cd current
+ autoheader && autoconf && ./configure
+
+ Then run:
+
+ gmake freebsd-dist
+
+ which creates a gzip'ed tar archive. Sadly, you cannot use make
+ freebsd-upload on the Sourceforge machine (no ncftpput). You now have to
+ manually upload the archive to Sourceforge's ftp server and release the
+ file publicly. Use the release notes and Change Log from the source
+ tarball package.
+
+ --------------------------------------------------------------------------
+
+ 6.3.10. HP-UX 11
+
+ First, make sure that you have freshly exported the right version into an
+ empty directory. (See "Building and releasing packages" above). Then run:
+
+ cd current
+ autoheader && autoconf && ./configure
+
+ Then do FIXME.
+
+ --------------------------------------------------------------------------
+
+ 6.3.11. Amiga OS
+
+ First, make sure that you have freshly exported the right version into an
+ empty directory. (See "Building and releasing packages" above). Then run:
+
+ cd current
+ autoheader && autoconf && ./configure
+
+ Then do FIXME.
+
+ --------------------------------------------------------------------------
+
+ 6.3.12. AIX
+
+ Login to Sourceforge's compilefarm via ssh:
+
+ ssh cf.sourceforge.net
+
+ Choose the right operating system. When logged in, make sure that you have
+ freshly exported the right version into an empty directory. (See "Building
+ and releasing packages" above). Then run:
+
+ cd current
+ autoheader && autoconf && ./configure
+
+ Then run:
+
+ make aix-dist
+
+ which creates a gzip'ed tar archive. Sadly, you cannot use make aix-upload
+ on the Sourceforge machine (no ncftpput). You now have to manually upload
+ the archive to Sourceforge's ftp server and release the file publicly. Use
+ the release notes and Change Log from the source tarball package.
+
+ --------------------------------------------------------------------------
+
+ 6.4. Uploading and Releasing Your Package
+
+ After the package is ready, it is time to upload it to SourceForge, and go
+ through the release steps. The upload is done via FTP:
+
+ * Upload to: ftp://upload.sourceforge.net/incoming
+
+ * user: anonymous
+
+ * password: ijbswa-developers@lists.sourceforge.net
+
+ Or use the make targets as described above.
+
+ Once this done go to
+ http://sourceforge.net/project/admin/editpackages.php?group_id=11118,
+ making sure you are logged in. Find your target platform in the second
+ column, and click Add Release. You will then need to create a new release
+ for your package, using the format of $VERSION ($CODE_STATUS), e.g. 3.0.8
+ (beta).
+
+ Now just follow the prompts. Be sure to add any appropriate Release notes.
+ You should see your freshly uploaded packages in "Step 2. Add Files To
+ This Release". Check the appropriate box(es). Remember at each step to hit
+ the "Refresh/Submit" buttons! You should now see your file(s) listed in
+ Step 3. Fill out the forms with the appropriate information for your
+ platform, being sure to hit "Update" for each file. If anyone is
+ monitoring your platform, check the "email" box at the very bottom to
+ notify them of the new package. This should do it!
+
+ If you have made errors, or need to make changes, you can go through
+ essentially the same steps, but select Edit Release, instead of Add
+ Release.
+
+ --------------------------------------------------------------------------
+
+ 6.5. After the Release
+
+ When all (or: most of the) packages have been uploaded and made available,
+ send an email to the announce mailing list, Subject: "Version X.Y.Z
+ available for download". Be sure to include the download location, the
+ release notes and the Changelog. Also, post an updated News item on the
+ project page Sourceforge, and update the Home page and docs linked from
+ the Home page (see below). Other news sites and release oriented sites,
+ such as Freshmeat, should also be notified.
+
+ --------------------------------------------------------------------------
+
+7. Update the Webserver
+
+ The webserver should be updated at least with each stable release. When
+ updating, please follow these steps to make sure that no broken links,
+ inconsistent contents or permission problems will occur (as it has many
+ times in the past!):
+
+ If you have changed anything in the stable-branch documentation source
+ SGML files, do:
+
+ make dok dok-pdf # (or 'make redhat-dok dok-pdf' if 'make dok' doesn't work for you)
+
+ That will generate doc/webserver/user-manual,
+ doc/webserver/developer-manual, doc/webserver/faq, doc/pdf/*.pdf and
+ doc/webserver/index.html automatically.
+
+ If you changed the manual page sources, generate
+ doc/webserver/man-page/privoxy-man-page.html by running "make man". (This
+ is a separate target due to dependencies on some obscure perl scripts [now
+ in CVS, but not well tested]. See comments in GNUmakefile.)
+
+ If you want to add new files to the webserver, create them locally in the
+ doc/webserver/* directory (or create new directories under doc/webserver).
+
+ Next, commit any changes from the above steps to CVS. All set? If these
+ are docs in the stable branch, then do:
+
+ make webserver
+
+ This will do the upload to the webserver (www.privoxy.org) and ensure all
+ files and directories there are group writable.
+
+ Please do NOT use any other means of transferring files to the webserver
+ to avoid permission problems. Also, please do not upload docs from
+ development branches or versions. The publicly posted docs should be in
+ sync with the last official release.
+
+ --------------------------------------------------------------------------
+
+8. Contacting the developers, Bug Reporting and Feature Requests
+
+ We value your feedback. In fact, we rely on it to improve Privoxy and its
+ configuration. However, please note the following hints, so we can provide
+ you with the best support:
+
+ --------------------------------------------------------------------------
+
+ 8.1. Get Support
+
+ For casual users, our support forum at SourceForge is probably best
+ suited: http://sourceforge.net/tracker/?group_id=11118&atid=211118
+
+ All users are of course welcome to discuss their issues on the users
+ mailing list, where the developers also hang around.
+
+ Note that the Privoxy mailing lists are moderated. Posts from unsubscribed
+ addresses have to be accepted manually by a moderator. This may cause a
+ delay of several days and if you use a subject that doesn't clearly
+ mention Privoxy or one of its features, your message may be accidentally
+ discarded as spam.
+
+ If you aren't subscribed, you should therefore spend a few seconds to come
+ up with a proper subject. Additionally you should make it clear that you
+ want to get CC'd. Otherwise some responses will be directed to the mailing
+ list only, and you won't see them.
+
+ --------------------------------------------------------------------------
+
+ 8.2. Reporting Problems
+
+ "Problems" for our purposes, come in two forms:
+
+ * Configuration issues, such as ads that slip through, or sites that
+ don't function properly due to one Privoxy "action" or another being
+ turned "on".
+
+ * "Bugs" in the programming code that makes up Privoxy, such as that
+ might cause a crash.
+
+ --------------------------------------------------------------------------
+
+ 8.2.1. Reporting Ads or Other Configuration Problems
+
+ Please send feedback on ads that slipped through, innocent images that
+ were blocked, sites that don't work properly, and other configuration
+ related problem of default.action file, to
+ http://sourceforge.net/tracker/?group_id=11118&atid=460288, the Actions
+ File Tracker.
+
+ New, improved default.action files may occasionally be made available
+ based on your feedback. These will be announced on the ijbswa-announce
+ list and available from our the files section of our project page.
+
+ --------------------------------------------------------------------------
+
+ 8.2.2. Reporting Bugs
+
+ Please report all bugs through our bug tracker:
+ http://sourceforge.net/tracker/?group_id=11118&atid=111118.
+
+ Before doing so, please make sure that the bug has not already been
+ submitted and observe the additional hints at the top of the submit form.
+ If already submitted, please feel free to add any info to the original
+ report that might help to solve the issue.
+
+ Please try to verify that it is a Privoxy bug, and not a browser or site
+ bug or documented behaviour that just happens to be different than what
+ you expected. If unsure, try toggling off Privoxy, and see if the problem
+ persists.
+
+ If you are using your own custom configuration, please try the stock
+ configs to see if the problem is configuration related. If you're having
+ problems with a feature that is disabled by default, please ask around on
+ the mailing list if others can reproduce the problem.
+
+ If you aren't using the latest Privoxy version, the bug may have been
+ found and fixed in the meantime. We would appreciate if you could take the
+ time to upgrade to the latest version (or even the latest CVS snapshot)
+ and verify that your bug still exists.
+
+ Please be sure to provide the following information:
+
+ * The exact Privoxy version you are using (if you got the source from
+ CVS, please also provide the source code revisions as shown in
+ http://config.privoxy.org/show-version).
+
+ * The operating system and versions you run Privoxy on, (e.g. Windows XP
+ SP2), if you are using a Unix flavor, sending the output of "uname -a"
+ should do, in case of GNU/Linux, please also name the distribution.
+
+ * The name, platform, and version of the browser you were using (e.g.
+ Internet Explorer v5.5 for Mac).
+
+ * The URL where the problem occurred, or some way for us to duplicate
+ the problem (e.g. http://somesite.example.com/?somethingelse=123).
+
+ * Whether your version of Privoxy is one supplied by the Privoxy
+ developers via SourceForge, or if you got your copy somewhere else.
+
+ * Whether you are using Privoxy in tandem with another proxy such as
+ Tor. If so, please temporary disable the other proxy to see if the
+ symptoms change.
+
+ * Whether you are using a personal firewall product. If so, does Privoxy
+ work without it?
+
+ * Any other pertinent information to help identify the problem such as
+ config or log file excerpts (yes, you should have log file entries for
+ each action taken).
+
+ You don't have to tell us your actual name when filing a problem report,
+ but please use a nickname so we can differentiate between your messages
+ and the ones entered by other "anonymous" users that may respond to your
+ request if they have the same problem or already found a solution.
+
+ Please also check the status of your request a few days after submitting
+ it, as we may request additional information. If you use a SF id, you
+ should automatically get a mail when someone responds to your request.
+
+ The appendix of the Privoxy User Manual also has helpful information on
+ understanding actions, and action debugging.
+
+ --------------------------------------------------------------------------
+
+ 8.3. Request New Features
+
+ You are welcome to submit ideas on new features or other proposals for
+ improvement through our feature request tracker at
+ http://sourceforge.net/tracker/?atid=361118&group_id=11118.
+
+ --------------------------------------------------------------------------
+
+ 8.4. Other
+
+ For any other issues, feel free to use the mailing lists. Technically
+ interested users and people who wish to contribute to the project are also
+ welcome on the developers list! You can find an overview of all
+ Privoxy-related mailing lists, including list archives, at:
+ http://sourceforge.net/mail/?group_id=11118.

+
+ 9.2. History
+
+ A long time ago, there was the Internet Junkbuster, by Anonymous Coders
+ and Junkbusters Corporation. This saved many users a lot of pain in the
+ early days of web advertising and user tracking.
+
+ But the web, its protocols and standards, and with it, the techniques for
+ forcing ads on users, give up autonomy over their browsing, and for
+ tracking them, keeps evolving. Unfortunately, the Internet Junkbuster did
+ not. Version 2.0.2, published in 1998, was (and is) the last official
+ release available from Junkbusters Corporation. Fortunately, it had been
+ released under the GNU GPL, which allowed further development by others.
+
+ So Stefan Waldherr started maintaining an improved version of the
+ software, to which eventually a number of people contributed patches. It
+ could already replace banners with a transparent image, and had a first
+ version of pop-up killing, but it was still very closely based on the
+ original, with all its limitations, such as the lack of HTTP/1.1 support,
+ flexible per-site configuration, or content modification. The last release
+ from this effort was version 2.0.2-10, published in 2000.
+
+ Then, some developers picked up the thread, and started turning the
+ software inside out, upside down, and then reassembled it, adding many new
+ features along the way.
+
+ The result of this is Privoxy, whose first stable version, 3.0, was
+ released August, 2002.
