- <sect id="nmu">Non-Maintainer Uploads (NMUs)
- <p>
-Under certain circumstances it is necessary for someone other than the
-official package maintainer to make a release of a package. This is
-called a non-maintainer upload, or NMU.
- <p>
-Debian porters, who compile packages for different architectures,
-occasionally do binary-only NMUs as part of their porting activity
-(see <ref id="porting">). Another reason why NMUs are done is when a
-Debian developers needs to fix another developers' packages in order to
-address serious security problems or crippling bugs, especially during
-the freeze, or when the package maintainer is unable to release a fix
-in a timely fashion.
- <p>
-This chapter contains information providing guidelines for when and
-how NMUs should be done. A fundamental distinction is made between
-source and binary-only NMUs, which is explained in the next section.
-
- <sect1 id="nmu-terms">Terminology
- <p>
-There are two new terms used throughout this section: ``binary-only NMU''
-and ``source NMU''. These terms are used with specific technical
-meaning throughout this document. Both binary-only and source NMUs are
-similar, since they involve an upload of a package by a developer who
-is not the official maintainer of that package. That is why it's a
-<em>non-maintainer</em> upload.
- <p>
-A source NMU is an upload of a package by a developer who is not the
-official maintainer, for the purposes of fixing a bug in the package.
-Source NMUs always involves changes to the source (even if it is just
-a change to <file>debian/changelog</file>). This can be either a
-change to the upstream source, or a change to the Debian bits of the
-source. Note, however, that source NMUs may also include
-architecture-dependent packages, as well as an updated Debian diff.
- <p>
-A binary-only NMU is a recompilation and upload of a binary package
-for a given architecture. As such, it is usually part of a porting
-effort. A binary-only NMU is a non-maintainer uploaded binary version
-of a package, with no source changes required. There are many cases
-where porters must fix problems in the source in order to get them to
-compile for their target architecture; that would be considered a
-source NMU rather than a binary-only NMU. As you can see, we don't
-distinguish in terminology between porter NMUs and non-porter NMUs.
+name="dpkg-scanpackages" section="8"> and
+<url id="&url-bts-devel;#maintincorrect">.
<p>
-Both classes of NMUs, source and binary-only, can be lumped by the
-term ``NMU''. However, this often leads to confusion, since most
-people think ``source NMU'' when they think ``NMU''. So it's best to
-be careful. In this chapter, if we use the unqualified term ``NMU'',
-we refer to any type of non-maintainer upload NMUs, whether source and
-binary, or binary-only.
+Note also that the term "section" is used for the separation of packages
+according to their licensing, e.g. <em>main</em>, <em>contrib</em> and
+<em>non-free</em>. This is described in another section, <ref id="archive">.
- <sect1 id="nmu-who">Who can do an NMU
+ <sect id="bug-handling">Handling package bugs
<p>
-Only official, registered Debian maintainers can do binary or source
-NMUs. An official maintainer is someone who has their key in the
-Debian key ring. Non-developers, however, are encouraged to download
-the source package and start hacking on it to fix problems; however,
-rather than doing an NMU, they should just submit worthwhile patches
-to the Bug Tracking System. Maintainers almost always appreciate
-quality patches and bug reports.
-
+Often as a package maintainer, you find bugs in other packages or else
+have bugs reported to your packages which need to be reassigned. The
+<url id="&url-bts-control;" name="BTS instructions"> can tell you how
+to do this. Some information on filing bugs can be found in <ref
+id="submit-bug">.
- <sect1 id="nmu-when">When to do a source NMU
+ <sect1>Monitoring bugs
<p>
-Guidelines for when to do a source NMU depend on the target
-distribution, i.e., stable, unstable, or experimental. Porters have
-slightly different rules than non-porters, due to their unique
-circumstances (see <ref id="source-nmu-when-porter">).
+If you want to be a good maintainer, you should periodically check the
+<url id="&url-bts;" name="Debian bug tracking system (BTS)"> for your
+packages. The BTS contains all the open bugs against your packages.
+You can check them by browsing this page:
+<tt>http://&bugs-host;/<var>yourlogin</var>@debian.org</tt>.
<p>
-When a security bug is detected, a fixed package should be uploaded
-as soon as possible. In this case, the Debian security officers get in
-contact with the package maintainer to make sure a fixed package is
-uploaded within a reasonable time (less than 48 hours). If the package
-maintainer cannot provide a fixed package fast enough or if he/she
-cannot be reached in time, a security officer may upload a fixed
-package (i.e., do a source NMU).
+Maintainers interact with the BTS via email addresses at
+<tt>&bugs-host;</tt>. Documentation on available commands can be
+found at <url id="&url-bts;">, or, if you have installed the
+<package>doc-debian</package> package, you can look at the local files
+&file-bts-docs;.
<p>
-During the release cycle (see <ref id="sec-dists">), NMUs which fix
-serious or higher severity bugs are encouraged and accepted. Even
-during this window, however, you should endeavor to reach the current
-maintainer of the package; they might be just about to upload a fix
-for the problem. As with any source NMU, the guidelines found in <ref
-id="nmu-guidelines"> need to be followed.
+Some find it useful to get periodic reports on open bugs. You can add
+a cron job such as the following if you want to get a weekly email
+outlining all the open bugs against your packages:
+<example>
+# ask for weekly reports of bugs in my packages
+&cron-bug-report;
+</example>
+Replace <var>address</var> with your official Debian
+maintainer address.
+
+ <sect1 id="bug-answering">Responding to bugs
<p>
-Bug fixes to unstable by non-maintainers are also acceptable, but only
-as a last resort or with permission. The following protocol should
-be respected to do an NMU:
+Make sure that any discussion you have about bugs are sent both to

+Once you've dealt with a bug report (e.g. fixed it), mark it as
+<em>done</em> (close it) by sending an explanation message to
+<email>123-done@bugs.debian.org</email>. If you're fixing a bug by
+changing and uploading the package, you can automate bug closing as
+described in <ref id="upload-bugfix">.
<p>
-The following applies to porters insofar as they are playing the dual
-role of being both package bug-fixers and package porters. If a
-porter has to change the Debian source archive, automatically their
-upload is a source NMU and is subject to its rules. If a porter is
-simply uploading a recompiled binary package, the rules are different;
-see <ref id="porter-guidelines">.
+You should <em>never</em> close bugs via the bug server <tt>close</tt>
+command sent to &email-bts-control;. If you do so, the original
+submitter will not receive any information about why the bug was
+closed.
+
+ <sect1 id="bug-housekeeping">Bug housekeeping
<p>
-First and foremost, it is critical that NMU patches to source should
-be as non-disruptive as possible. Do not do housekeeping tasks, do
-not change the name of modules or files, do not move directories; in
-general, do not fix things which are not broken. Keep the patch as
-small as possible. If things bother you aesthetically, talk to the
-Debian maintainer, talk to the upstream maintainer, or submit a bug.
-However, aesthetic changes must <em>not</em> be made in a non-maintainer
-upload.
+As a package maintainer, you will often find bugs in other packages or
+have bugs reported against your packages which are actually bugs in
+other packages. The bug tracking system's features interesting to developers
+are described in the <url id="&url-bts-devel;" name="BTS documentation for
+Debian developers">. Operations such as reassigning, merging, and tagging
+bug reports are described in the <url id="&url-bts-control;" name="BTS
+control bot documentation">. This section contains
+some guidelines for managing your own bugs, based on the collective
+Debian developer experience.
+ <p>
+Filing bugs for problems that you find in other packages is one of
+the "civic obligations" of maintainership, see <ref id="submit-bug">
+for details. However, handling the bugs in your own packages is
+even more important.
+ <p>
+Here's a list of steps that you may follow to handle a bug report:
+<enumlist>
+ <item>
+Decide whether the report corresponds to a real bug or not. Sometimes
+users are just calling a program in the wrong way because they haven't
+read the documentation. If you diagnose this, just close the bug with
+enough information to let the user correct his problem (give pointers
+to the good documentation and so on). If the same report comes up
+again and again you may ask yourself if the documentation is good
+enough or if the program shouldn't detect its misuse in order to
+give an informative error message. This is an issue that may need
+to be brought to the upstream author.
+ <p>
+If the bug submitter disagree with your decision to close the bug,
+they may reopen it until you find an agreement on how to handle it.
+If you don't find any, you may want to tag the bug <tt>wontfix</tt>
+to let people know that the bug exists but that it won't be corrected.
+If this situation is unacceptable, you (or the submitter) may want to
+require a decision of the technical committee by reassigning the bug
+to <package>tech-ctte</package> (you may use the clone command of
+the BTS if you wish to keep it reported against your package). Before
+doing so, please read the <url id="&url-tech-ctte;" name="recommended procedure">.
+ <item>
+If the bug is real but it's caused by another package, just reassign
+the bug the right package. If you don't know which package it should
+be reassigned to, you may either ask for help on &email-debian-devel; or
+reassign it to <package>debian-policy</package> to let them decide which
+package is in fault.
+ <p>
+Sometimes you also have to adjust the severity of the bug so that it
+matches our definition of the severity. That's because people tend to
+inflate the severity of bugs to make sure their bugs are fixed quickly.
+Some bugs may even be dropped to wishlist severity when the requested
+change is just cosmetic.
+ <item>
+The bug submitter may have forgotten to provide some information, in that
+case you have to ask him the information required. You may use the
+<tt>moreinfo</tt> tag to mark the bug as such. Moreover if you can't
+reproduce the bug, you tag it <tt>unreproducible</tt>. Anyone who
+can reproduce the bug is then invited to provide more information
+on how to reproduce it. After a few months, if this information has not
+been sent by someone, the bug may be closed.
+ <item>
+If the bug is related to the packaging, you just fix it. If you are not
+able to fix it yourself, then tag the bug as <tt>help</tt>. You can
+also ask for help on &email-debian-devel; or &email-debian-qa;. If it's an
+upstream problem, you have to forward it to the upstream author.
+Forwarding a bug is not enough, you have to check at each release if
+the bug has been fixed or not. If it has, you just close it, otherwise
+you have to remind the author about it. If you have the required skills
+you can prepare a patch that fixes the bug and that you send at the
+same time to the author. Make sure to send the patch in the BTS and to
+tag the bug as <tt>patch</tt>.
+ <item>
+If you have fixed a bug in your local copy, or if a fix has been
+committed to the CVS repository, you may tag the bug as
+<tt>pending</tt> to let people know that the bug is corrected and that
+it will be closed with the next upload (add the <tt>closes:</tt> in
+the <file>changelog</file>). This is particularly useful if you
+are several developers working on the same package.
+ <item>
+Once a corrected package is available in the <em>unstable</em>
+distribution, you can close the bug. This can be done automatically,
+read <ref id="upload-bugfix">.
+</enumlist>
+ <sect1 id="upload-bugfix">When bugs are closed by new uploads
+ <p>
+If you fix a bug in your packages, it is your responsibility as the
+package maintainer to close the bug when it has been fixed. However,
+you should not close the bug until the package which fixes the bug has
+been accepted into the Debian archive. Therefore, once you get
+notification that your updated package has been installed into the
+archive, you can and should close the bug in the BTS.
+ <p>
+However, it's possible to avoid having to manually close bugs after the
+upload -- just list the fixed bugs in your <file>debian/changelog</file>
+file, following a certain syntax, and the archive maintenance software
+will close the bugs for you. For example:
- <sect2 id="nmu-version">Source NMU version numbering
- <p>
-Whenever you have made a change to a package, no matter how trivial,
-the version number needs to change. This enables our packing system
-to function.
- <p>
-If you are doing a non-maintainer upload (NMU), you should add a new
-minor version number to the <var>debian-revision</var> part of the
-version number (the portion after the last hyphen). This extra minor
-number will start at `1'. For example, consider the package `foo',
-which is at version 1.1-3. In the archive, the source package control
-file would be <file>foo_1.1-3.dsc</file>. The upstream version is
-`1.1' and the Debian revision is `3'. The next NMU would add a new
-minor number `.1' to the Debian revision; the new source control file
-would be <file>foo_1.1-3.1.dsc</file>.
- <p>
-The Debian revision minor number is needed to avoid stealing one of
-the package maintainer's version numbers, which might disrupt their
-work. It also has the benefit of making it visually clear that a
-package in the archive was not made by the official maintainer.
- <p>
-If there is no <var>debian-revision</var> component in the version
-number then one should be created, starting at `0.1'. If it is
-absolutely necessary for someone other than the usual maintainer to
-make a release based on a new upstream version then the person making
-the release should start with the <var>debian-revision</var> value
-`0.1'. The usual maintainer of a package should start their
-<var>debian-revision</var> numbering at `1'. Note that if you do
-this, you'll have to invoke <prgn>dpkg-buildpackage</prgn> with the
-<tt>-sa</tt> switch to force the build system to pick up the new
-source package (normally it only looks for Debian revisions of '0' or
-'1' — it's not yet clever enough to know about `0.1').
+<example>
+acme-cannon (3.1415) unstable; urgency=low
+ * Frobbed with options (closes: Bug#98339)
+ * Added safety to prevent operator dismemberment, closes: bug#98765,
+ bug#98713, #98714.
+ * Added man page. Closes: #98725.
+</example>
- <sect2 id="nmu-changelog">
- <heading>Source NMUs must have a new changelog entry</heading>
- <p>
-A non-maintainer doing a source NMU must create a changelog entry,
-describing which bugs are fixed by the NMU, and generally why the NMU
-was required and what it fixed. The changelog entry will have the
-non-maintainer's email address in the log entry and the NMU version
-number in it.
- <p>
-By convention, source NMU changelog entries start with the line
+Technically speaking, the following Perl regular expression is what is
+used:
<example>
- * Non-maintainer upload
+ /closes:\s*(?:bug)?\#\s*\d+(?:,\s*(?:bug)?\#\s*\d+)*/ig
</example>
+The author prefers the <tt>closes: #<var>XXX</var></tt> syntax, as
+one of the most concise and easiest to integrate with the text of the
+<file>changelog</file>.
+ <p>
+If you happen to mistype a bug number or forget one in the changelog file,
+don't hesitate to undo any damage the error caused. To reopen wrongly closed
+bugs, send an <tt>reopen <var>XXX</var></tt> command in the bug tracking
+system's control bot. To close any remaining bugs that were fixed by your
+upload, email the <file>.changes</file> file to
+<email>XXX-done@bugs.debian.org</email>, where <var>XXX</var> is your
+bug number.
+ <p>
+Bear in mind that it is not obligatory to close bugs using the changelog
+like described above -- if you simply want to close bugs that don't have
+anything to do with an upload of yours, do it simply by emailing an
+explanation to <email>XXX-done@bugs.debian.org</email>.
- <sect2 id="nmu-patch">Source NMUs and the Bug Tracking System
- <p>
-Maintainers other than the official package maintainer should make as
-few changes to the package as possible, and they should always send a
-patch as a unified context diff (<tt>diff -u</tt>) detailing their
-changes to the Bug Tracking System.
- <p>
-What if you are simply recompiling the package? If you just need to
-recompile it for a single architecture, then you may do a binary-only
-NMU as described in <ref id="binary-only-nmu"> which doesn't require any
-patch to be sent. If you want the package to be recompiled for all
-architectures, then you do a source NMU as usual and you will have to
-send a patch.
- <p>
-If the source NMU (non-maintainer upload) fixes some existing bugs,
-these bugs should be tagged <em>fixed</em> in the Bug Tracking
-System rather than closed. By convention, only the official package
-maintainer or the original bug submitter are allowed to close bugs.
-Fortunately, Debian's archive system recognizes NMUs and thus marks
-the bugs fixed in the NMU appropriately if the person doing the NMU
-has listed all bugs in the changelog with the <tt>Closes:
-bug#<var>nnnnn</var></tt> syntax (see <ref id="upload-bugfix"> for
-more information describing how to close bugs via the changelog).
-Tagging the bugs <em>fixed</em> ensures that everyone knows that the
-bug was fixed in an NMU; however the bug is left open until the
-changes in the NMU are incorporated officially into the package by
-the official package maintainer.
- <p>
-Also, after doing an NMU, you have to open a new bug and include a
-patch showing all the changes you have made. Alternatively you can send
-that information to the existing bugs that are fixed by your NMU.
-The normal maintainer will either apply the patch or employ an alternate
-method of fixing the problem. Sometimes bugs are fixed independently
-upstream, which is another good reason to back out an NMU's patch.
-If the maintainer decides not to apply the NMU's patch but to release a
-new version, the maintainer needs to ensure that the new upstream version
-really fixes each problem that was fixed in the non-maintainer release.
- <p>
-In addition, the normal maintainer should <em>always</em> retain the
-entry in the changelog file documenting the non-maintainer upload.

-Debian supports an ever-increasing number of architectures. Even if

-portability. Therefore, even if you are not a porter, you should read
-most of this chapter.
- <p>
-Porting is the act of building Debian packages for architectures that
-is different from the original architecture of the package
-maintainer's binary package. It is a unique and essential activity.
-In fact, porters do most of the actual compiling of Debian packages.
-For instance, for a single <em>i386</em> binary package, there must be

- <p>
-Porters have a difficult and unique task, since they are required to
-deal with a large volume of packages. Ideally, every source package

-committed by Debian maintainers — common problems which often stymie
-porters, and make their jobs unnecessarily difficult.
- <p>
-The first and most important watchword is to respond quickly to bug or
-issues raised by porters. Please treat porters with courtesy, as if
-they were in fact co-maintainers of your package (which in a way, they
-are). Please be tolerant of succinct or even unclear bug reports,
-doing your best to hunt down whatever the problem is.
- <p>
-By far, most of the problems encountered by porters are caused by
-<em>packaging bugs</em> in the source packages. Here is a checklist
+</list>
+
+ <sect2 id="bug-security-confidentiality">Confidentiality
+ <p>
+Unlike most other activities within Debian, information about security
+issues must sometimes be kept private for a time. Whether this is the
+case depends on the nature of the problem and corresponding fix, and
+whether it is already a matter of public knowledge.
+<p>
+There are a few ways a developer can learn of a security problem:
+
+<list compact>
+ <item>he notices it on a public forum (mailing list, web site, etc.)
+ <item>someone files a bug report
+ <item>someone informs him via private email
+</list>
+
+ In the first two cases, the information is public and it is important
+ to have a fix as soon as possible. In the last case, however, it
+ might not be public information. In that case there are a few
+ possible options for dealing with the problem:
+
+<list>
+ <item>if it is a trivial problem (like insecure temporary files)
+ there is no need to keep the problem a secret and a fix should be
+ made and released.
+
+ <item>if the problem is severe (remotely exploitable, possibility to
+ gain root privileges) it is preferable to share the information with
+ other vendors and coordinate a release. The security team keeps
+ contacts with the various organizations and individuals and can take
+ care of that.
+</list>
+
+<p>
+ In all cases if the person who reports the problem asks to not
+ disclose the information that should be respected, with the obvious
+ exception of informing the security team (make sure you tell the
+ security team that the information can not be disclosed).
+
+<p>
+Please note that if secrecy is needed you can also not upload a fix to
+unstable (or anywhere else), since the changelog and diff information
+for unstable is public.
+
+<p>
+There are two reasons for releasing information even though secrecy is
+requested: the problem has been known for a while, or that the problem

+ <heading>Preparing packages to address security issues</heading>
+ <p>
+One way that you can assist the security team in their duties is to
+provide fixed packages suitable for a security advisory for the stable
+Debian release.
+ <p>
+ When an update is made to the stable release, care must be taken to
+ avoid changing system behavior or introducing new bugs. In order to
+ do this, make as few changes as possible to fix the bug. Users and
+ administrators rely on the exact behavior of a release once it is
+ made, so any change that is made might break someone's system.
+ This is especially true of libraries: make sure you never change the
+ API or ABI, no matter how small the change.
+<p>
+This means that moving to a new upstream version is not a good
+solution. Instead, the relevant changes should be back-ported to the
+version present in the current stable Debian release. Generally,
+upstream maintainers are willing to help if needed. If not, the
+Debian security team may be able to help.
+<p>
+In some cases, it is not possible to back-port a security fix, for
+example when large amounts of source code need to be modified or
+rewritten. If this happens, it may be necessary to move to a new
+upstream version. However, you must always coordinate that with the
+security team beforehand.
+<p>
+Related to this is another important guideline: always test your
+changes. If you have an exploit available, try it and see if it
+indeed succeeds on the unpatched package and fails on the fixed
+package. Test other, normal actions as well, as sometimes a security
+fix can break seemingly unrelated features in subtle ways.
+<p>
+Review and test your changes as much as possible. Check the
+differences from the previous version repeatedly
+(<prgn>interdiff</prgn> from the <package>patchutils</package> package
+and <prgn>debdiff</prgn> from <package>devscripts</package> are useful tools for
+this).
+
+When packaging the fix, keep the following points in mind:
+
+<list>
+ <item>Make sure you target the right distribution in your
+ <file>debian/changelog</file>. For stable this is <tt>stable-security</tt> and for
+ testing this is <tt>testing-security</tt>, and for the previous
+ stable release, this is <tt>oldstable-security</tt>. Do not target
+ <var>distribution</var>-proposed-updates!
+
+ <item>Make sure the version number is proper. It must be greater
+ than the current package, but less than package versions in later
+ distributions. If in doubt, test it with <tt>dpkg
+ --compare-versions</tt>. For <em>testing</em>, there must be
+ a higher version in <em>unstable</em>. If there is none yet (for example,
+ if <em>testing</em> and <em>unstable</em> have the same version) you must upload a
+ new version to unstable first.
+
+ <item>Do not make source-only uploads if your package has any
+ binary-all packages (do not use the <tt>-S</tt> option to
+ <prgn>dpkg-buildpackage</prgn>). The <prgn>buildd</prgn> infrastructure will
+ not build those. This point applies to normal package uploads as
+ well.
+
+ <item>If the upstream source has been uploaded to
+ security.debian.org before (by a previous security update), build
+ the upload without the upstream source (<tt>dpkg-buildpackage
+ -sd</tt>). Otherwise, build with full source
+ (<tt>dpkg-buildpackage -sa</tt>).
+
+ <item>Be sure to use the exact same <file>*.orig.tar.gz</file> as used in the
+ normal archive, otherwise it is not possible to move the security
+ fix into the main archives later.
+
+ <item>Be sure, when compiling a package, to compile on a clean
+ system which only has packages installed from the distribution you
+ are building for. If you do not have such a system yourself, you
+ can use a debian.org machine (see <ref id="server-machines">)
+ or setup a chroot (see <ref id="pbuilder"> and
+ <ref id="debootstrap">).
+</list>
+
+ <sect2 id="bug-security-upload">Uploading the fixed package
+<p>
+<em>DO NOT</em> upload a package to the security upload queue without
+prior authorization from the security team. If the package does not
+exactly meet the team's requirements, it will cause many problems and
+delays in dealing with the unwanted upload.
+<p>
+<em>DO NOT</em> upload your fix to proposed-updates without
+coordinating with the security team. Packages from
+security.debian.org will be copied into the proposed-updates directory
+automatically. If a package with the same or a higher version number
+is already installed into the archive, the security update will be
+rejected by the archive system. That way, the stable distribution
+will end up without a security update for this package instead.
+<p>
+Once you have created and tested the new package and it has been
+approved by the security team, it needs to be uploaded so that it can
+be installed in the archives. For security uploads, the place to
+upload to is
+<tt>ftp://security.debian.org/pub/SecurityUploadQueue/</tt> .
+
+<p>
+Once an upload to the security queue has been accepted, the package
+will automatically be rebuilt for all architectures and stored for
+verification by the security team.
+
+<p>
+Uploads which are waiting for acceptance or verification are only
+accessible by the security team. This is necessary since there might
+be fixes for security problems that cannot be disclosed yet.
+
+<p>
+If a member of the security team accepts a package, it will be

+cases.
+
+ <sect1 id="moving-pkgs">Moving packages
+ <p>
+Sometimes a package will change its section. For instance, a

+`contrib'.<footnote> See the <url id="&url-debian-policy;"

+You also have to detail the reasons justifying that request. This is to
+avoid unwanted removals and to keep a trace of why a package has been
+removed. For example, you can provide the name of the package that
+supersedes the one to be removed.
+ <p>
+Usually you only ask the removal of a package maintained by yourself.
+If you want to remove another package, you have to get the approval
+of its last maintainer.
+ <p>
+If in doubt concerning whether a package is disposable, email
+&email-debian-devel; asking for opinions. Also of interest is the
+<prgn>apt-cache</prgn> program from the <package>apt</package>
+package. When invoked as <tt>apt-cache showpkg
+<var>package</var></tt>, the program will show details for
+<var>package</var>, including reverse depends.
+ <p>
+Once the package has been removed, the package's bugs should be handled.
+They should either be reassigned to another package in the case where
+the actual code has evolved into another package (e.g. <tt>libfoo12</tt>
+was removed because <tt>libfoo13</tt> supersedes it) or closed if the
+software is simply no more part of Debian.
+
+ <sect2>Removing packages from <file>Incoming</file>
+ <p>
+In the past, it was possible to remove packages from <file>incoming</file>.
+However, with the introduction of the new incoming system, this is no longer
+possible. Instead, you have to upload a new revision of your package with
+a higher version as the package you want to replace. Both versions will be
+installed in the archive but only the higher version will actually be
+available in <em>unstable</em> since the previous version will immediately
+be replaced by the higher. However, if you do proper testing of your
+packages, the need to replace a package should not occur too often anyway.
+
+ <sect1>Replacing or renaming packages
+ <p>
+Sometimes you made a mistake naming the package and you need to rename
+it. In this case, you need to follow a two-step process. First, set
+your <file>debian/control</file> file to replace and conflict with the
+obsolete name of the package (see the <url id="&url-debian-policy;"
+name="Debian Policy Manual"> for details). Once you've uploaded
+the package and the package has moved into the archive, file a bug
+against <tt>ftp.debian.org</tt> asking to remove the package with the
+obsolete name. Do not forget to properly reassign the package's bugs
+at the same time.
+ <p>
+At other times, you may make a mistake in constructing your package and
+wish to replace it. The only way to do this is to increase the version
+number and upload a new version. The old version will be expired in
+the usual manner. Note that this applies to each part of your package,
+including the sources: if you wish to replace the upstream source tarball
+of your package, you will need to upload it with a different version. An
+easy possibility is to replace <file>foo_1.00.orig.tar.gz</file> with
+<file>foo_1.00+0.orig.tar.gz</file>. This restriction gives each file
+on the ftp site a unique name, which helps to ensure consistency across the
+mirror network.
+
+ <sect1 id="orphaning">Orphaning a package
+ <p>
+If you can no longer maintain a package, you need to inform the others
+about that, and see that the package is marked as orphaned.
+You should set the package maintainer to <tt>Debian QA Group
+&orphan-address;</tt> and submit a bug report
+against the pseudo package <package>wnpp</package>. The bug report should be
+titled <tt>O: <var>package</var> -- <var>short description</var></tt>
+indicating that the package is now orphaned. The severity of the bug
+should be set to <em>normal</em>. If you feel it's necessary, send a copy
+to &email-debian-devel; by putting the address in the X-Debbugs-CC: header
+of the message (no, don't use CC:, because that way the message's subject
+won't indicate the bug number).
+ <p>
+If the package is especially crucial to Debian, you should instead submit
+a bug against <package>wnpp</package> and title it <tt>RFA: <var>package</var> --
+<var>short description</var></tt> and set its severity to
+<em>important</em>. <tt>RFA</tt> stands for <em>Request For Adoption</em>.
+Definitely copy the message to debian-devel in this case, as described
+above.

+packages listed in the WNPP, please take a look at the aforementioned
+page for information and procedures.
+ <p>
+It is not OK to simply take over a package that you feel is neglected
+— that would be package hijacking. You can, of course, contact the
+current maintainer and ask them if you may take over the package.
+If you have reason to believe a maintainer has gone AWOL
+(absent without leave), see <ref id="mia-qa">.
+ <p>
+Generally, you may not take over the package without the assent of the
+current maintainer. Even if they ignore you, that is still not grounds to
+take over a package. Complaints about maintainers should be brought up on
+the developers' mailing list. If the discussion doesn't end with a positive
+conclusion, and the issue is of a technical nature, consider bringing it to
+the attention of the technical committee (see the <url name="technical
+committee web page" id="&url-tech-ctte;"> for more information).
+ <p>
+If you take over an old package, you probably want to be listed as the
+package's official maintainer in the bug system. This will happen
+automatically once you upload a new version with an updated
+<tt>Maintainer:</tt> field, although it can take a few hours after the
+upload is done. If you do not expect to upload a new version for a while,
+you can use <ref id="pkg-tracking-system"> to get the bug reports. However,
+make sure that the old maintainer has no problem with the fact that
+they will continue to receive the bugs during that time.

+
+ <sect id="porting">Porting and being ported
+ <p>
+Debian supports an ever-increasing number of architectures. Even if
+you are not a porter, and you don't use any architecture but one, it
+is part of your duty as a maintainer to be aware of issues of
+portability. Therefore, even if you are not a porter, you should read
+most of this chapter.
+ <p>
+Porting is the act of building Debian packages for architectures that
+is different from the original architecture of the package
+maintainer's binary package. It is a unique and essential activity.
+In fact, porters do most of the actual compiling of Debian packages.
+For instance, for a single <em>i386</em> binary package, there must be
+a recompile for each architecture, which amounts to
+&number-of-arches; more builds.
+
+
+ <sect1 id="kind-to-porters">Being kind to porters
+ <p>
+Porters have a difficult and unique task, since they are required to
+deal with a large volume of packages. Ideally, every source package
+should build right out of the box. Unfortunately, this is often not
+the case. This section contains a checklist of ``gotchas'' often
+committed by Debian maintainers — common problems which often stymie
+porters, and make their jobs unnecessarily difficult.
+ <p>
+The first and most important watchword is to respond quickly to bug or
+issues raised by porters. Please treat porters with courtesy, as if
+they were in fact co-maintainers of your package (which in a way, they
+are). Please be tolerant of succinct or even unclear bug reports,
+doing your best to hunt down whatever the problem is.
+ <p>
+By far, most of the problems encountered by porters are caused by
+<em>packaging bugs</em> in the source packages. Here is a checklist
of things you should check or be aware of.

-
- <sect1 id="moving-pkgs">Moving packages
- <p>
-Sometimes a package will change its section. For instance, a

-`contrib'.<footnote> See the <url id="&url-debian-policy;"

- </footnote>
- <p>
-If you need to change the section for one of your packages, change the

-name="Debian Policy Manual"> for details). If your new section is

-override file updated, as described in <ref id="override-file">.
-
+Under certain circumstances it is necessary for someone other than the
+official package maintainer to make a release of a package. This is
+called a non-maintainer upload, or NMU.
+ <p>
+Debian porters, who compile packages for different architectures,
+occasionally do binary-only NMUs as part of their porting activity
+(see <ref id="porting">). Another reason why NMUs are done is when a
+Debian developers needs to fix another developers' packages in order to
+address serious security problems or crippling bugs, especially during
+the freeze, or when the package maintainer is unable to release a fix
+in a timely fashion.
+ <p>
+This chapter contains information providing guidelines for when and
+how NMUs should be done. A fundamental distinction is made between
+source and binary-only NMUs, which is explained in the next section.
- <sect1 id="removing-pkgs">Removing packages
- <p>
-If for some reason you want to completely remove a package (say, if it
-is an old compatibility library which is no longer required), you
-need to file a bug against <tt>ftp.debian.org</tt> asking that the
-package be removed. Make sure you indicate which distribution the
-package should be removed from. Normally, you can only have packages
-removed from <em>unstable</em> and <em>experimental</em>. Packages
-are not removed from <em>testing</em> directly. Rather, they will be
-removed automatically after the package has been removed from
-<em>unstable</em> and no package in <em>testing</em> depends on it.
+ <sect1 id="nmu-terms">Terminology
<p>
-You also have to detail the reasons justifying that request. This is to
-avoid unwanted removals and to keep a trace of why a package has been
-removed. For example, you can provide the name of the package that
-supersedes the one to be removed.
+There are two new terms used throughout this section: ``binary-only NMU''
+and ``source NMU''. These terms are used with specific technical
+meaning throughout this document. Both binary-only and source NMUs are
+similar, since they involve an upload of a package by a developer who
+is not the official maintainer of that package. That is why it's a
+<em>non-maintainer</em> upload.
<p>
-Usually you only ask the removal of a package maintained by yourself.
-If you want to remove another package, you have to get the approval
-of its last maintainer.
+A source NMU is an upload of a package by a developer who is not the
+official maintainer, for the purposes of fixing a bug in the package.
+Source NMUs always involves changes to the source (even if it is just
+a change to <file>debian/changelog</file>). This can be either a
+change to the upstream source, or a change to the Debian bits of the
+source. Note, however, that source NMUs may also include
+architecture-dependent packages, as well as an updated Debian diff.
<p>
-If in doubt concerning whether a package is disposable, email
-&email-debian-devel; asking for opinions. Also of interest is the
-<prgn>apt-cache</prgn> program from the <package>apt</package>
-package. When invoked as <tt>apt-cache showpkg
-<var>package</var></tt>, the program will show details for
-<var>package</var>, including reverse depends.
+A binary-only NMU is a recompilation and upload of a binary package
+for a given architecture. As such, it is usually part of a porting
+effort. A binary-only NMU is a non-maintainer uploaded binary version
+of a package, with no source changes required. There are many cases
+where porters must fix problems in the source in order to get them to
+compile for their target architecture; that would be considered a
+source NMU rather than a binary-only NMU. As you can see, we don't
+distinguish in terminology between porter NMUs and non-porter NMUs.
<p>
-Once the package has been removed, the package's bugs should be handled.
-They should either be reassigned to another package in the case where
-the actual code has evolved into another package (e.g. <tt>libfoo12</tt>
-was removed because <tt>libfoo13</tt> supersedes it) or closed if the
-software is simply no more part of Debian.
+Both classes of NMUs, source and binary-only, can be lumped by the
+term ``NMU''. However, this often leads to confusion, since most
+people think ``source NMU'' when they think ``NMU''. So it's best to
+be careful. In this chapter, if we use the unqualified term ``NMU'',
+we refer to any type of non-maintainer upload NMUs, whether source and
+binary, or binary-only.

+ <item>
+Wait a few more days. If you still haven't got an answer from the
+maintainer, send him a mail announcing your intent to NMU the package.
+Prepare an NMU as described in <ref id="nmu-guidelines">, test it
+carefully on your machine (cf. <ref id="upload-checking">).
+Double check that your patch doesn't have any unexpected side effects.
+Make sure your patch is as small and as non-disruptive as it can be.
+ <item>
+Upload your package to incoming in <file>DELAYED/7-day</file> (cf.
+<ref id="delayed-incoming">), send the final patch to the maintainer via
+the BTS, and explain to them that they have 7 days to react if they want

-Often as a package maintainer, you find bugs in other packages or else

-<url id="&url-bts-control;" name="BTS instructions"> can tell you how
-to do this. Some information on filing bugs can be found in <ref
-id="submit-bug">.
+At times, the release manager or an organized group of developers can
+announce a certain period of time in which the NMU rules are relaxed.
+This usually involves shortening the period during which one is to wait

- <sect1>Monitoring bugs
- <p>
-If you want to be a good maintainer, you should periodically check the
-<url id="&url-bts;" name="Debian bug tracking system (BTS)"> for your
-packages. The BTS contains all the open bugs against your packages.
-You can check them by browsing this page:
-<tt>http://&bugs-host;/<var>yourlogin</var>@debian.org</tt>.
+ <sect1 id="nmu-guidelines">How to do a source NMU
<p>
-Maintainers interact with the BTS via email addresses at
-<tt>&bugs-host;</tt>. Documentation on available commands can be
-found at <url id="&url-bts;">, or, if you have installed the
-<package>doc-debian</package> package, you can look at the local files
-&file-bts-docs;.
+The following applies to porters insofar as they are playing the dual
+role of being both package bug-fixers and package porters. If a
+porter has to change the Debian source archive, automatically their
+upload is a source NMU and is subject to its rules. If a porter is
+simply uploading a recompiled binary package, the rules are different;
+see <ref id="porter-guidelines">.
<p>
-Some find it useful to get periodic reports on open bugs. You can add
-a cron job such as the following if you want to get a weekly email
-outlining all the open bugs against your packages:
+First and foremost, it is critical that NMU patches to source should
+be as non-disruptive as possible. Do not do housekeeping tasks, do
+not change the name of modules or files, do not move directories; in
+general, do not fix things which are not broken. Keep the patch as
+small as possible. If things bother you aesthetically, talk to the
+Debian maintainer, talk to the upstream maintainer, or submit a bug.
+However, aesthetic changes must <em>not</em> be made in a non-maintainer

+ <sect2 id="nmu-version">Source NMU version numbering
+ <p>
+Whenever you have made a change to a package, no matter how trivial,
+the version number needs to change. This enables our packing system
+to function.
+ <p>
+If you are doing a non-maintainer upload (NMU), you should add a new
+minor version number to the <var>debian-revision</var> part of the
+version number (the portion after the last hyphen). This extra minor
+number will start at `1'. For example, consider the package `foo',
+which is at version 1.1-3. In the archive, the source package control
+file would be <file>foo_1.1-3.dsc</file>. The upstream version is
+`1.1' and the Debian revision is `3'. The next NMU would add a new
+minor number `.1' to the Debian revision; the new source control file
+would be <file>foo_1.1-3.1.dsc</file>.
+ <p>
+The Debian revision minor number is needed to avoid stealing one of
+the package maintainer's version numbers, which might disrupt their
+work. It also has the benefit of making it visually clear that a
+package in the archive was not made by the official maintainer.
+ <p>
+If there is no <var>debian-revision</var> component in the version
+number then one should be created, starting at `0.1'. If it is
+absolutely necessary for someone other than the usual maintainer to
+make a release based on a new upstream version then the person making
+the release should start with the <var>debian-revision</var> value
+`0.1'. The usual maintainer of a package should start their
+<var>debian-revision</var> numbering at `1'.
+

+ <sect2 id="nmu-changelog">
+ <heading>Source NMUs must have a new changelog entry</heading>
+ <p>
+A non-maintainer doing a source NMU must create a changelog entry,
+describing which bugs are fixed by the NMU, and generally why the NMU
+was required and what it fixed. The changelog entry will have the
+non-maintainer's email address in the log entry and the NMU version
+number in it.
+ <p>
+By convention, source NMU changelog entries start with the line
<example>
-# ask for weekly reports of bugs in my packages
-&cron-bug-report;
+ * Non-maintainer upload
</example>
-Replace <var>address</var> with your official Debian
-maintainer address.
- <sect1 id="bug-answering">Responding to bugs
+
+ <sect2 id="nmu-patch">Source NMUs and the Bug Tracking System
+ <p>
+Maintainers other than the official package maintainer should make as
+few changes to the package as possible, and they should always send a
+patch as a unified context diff (<tt>diff -u</tt>) detailing their
+changes to the Bug Tracking System.
+ <p>
+What if you are simply recompiling the package? If you just need to
+recompile it for a single architecture, then you may do a binary-only
+NMU as described in <ref id="binary-only-nmu"> which doesn't require any
+patch to be sent. If you want the package to be recompiled for all
+architectures, then you do a source NMU as usual and you will have to
+send a patch.
+ <p>
+If the source NMU (non-maintainer upload) fixes some existing bugs,
+these bugs should be tagged <em>fixed</em> in the Bug Tracking
+System rather than closed. By convention, only the official package
+maintainer or the original bug submitter are allowed to close bugs.
+Fortunately, Debian's archive system recognizes NMUs and thus marks
+the bugs fixed in the NMU appropriately if the person doing the NMU
+has listed all bugs in the changelog with the <tt>Closes:
+bug#<var>nnnnn</var></tt> syntax (see <ref id="upload-bugfix"> for
+more information describing how to close bugs via the changelog).
+Tagging the bugs <em>fixed</em> ensures that everyone knows that the
+bug was fixed in an NMU; however the bug is left open until the
+changes in the NMU are incorporated officially into the package by
+the official package maintainer.
+ <p>
+Also, after doing an NMU, you have to open a new bug and include a
+patch showing all the changes you have made. Alternatively you can send
+that information to the existing bugs that are fixed by your NMU.
+The normal maintainer will either apply the patch or employ an alternate
+method of fixing the problem. Sometimes bugs are fixed independently
+upstream, which is another good reason to back out an NMU's patch.
+If the maintainer decides not to apply the NMU's patch but to release a
+new version, the maintainer needs to ensure that the new upstream version
+really fixes each problem that was fixed in the non-maintainer release.
+ <p>
+In addition, the normal maintainer should <em>always</em> retain the
+entry in the changelog file documenting the non-maintainer upload.

-Make sure that any discussion you have about bugs are sent both to
-the original submitter of the bug, and the bug itself (e.g.,
-<email>123@bugs.debian.org</email>). If you're writing a new

-contact the submitter <em>and</em> to record your mail within the

+If one of your packages has been NMU'ed, you have to incorporate the

+In any case, you should not be upset by the NMU. An NMU is not a

+someone cares enough about the package and that they were willing to help
+you in your work, so you should be thankful. You may also want to

-have bugs reported against your packages which are actually bugs in
-other packages. The <url id="&url-bts-control;" name="BTS

-how to file, reassign, merge, and tag bugs. This section contains
-some guidelines for managing your own bugs, based on the collective
-Debian developer experience.
+
+ <sect id="collaborative-maint">
+ <heading>Collaborative maintenance</heading>
<p>
-Filing bugs for problems that you find in other packages is one of
-the "civic obligations" of maintainership, see <ref id="submit-bug">
-for details. However handling the bugs on your own packages is
-even more important.
+"Collaborative maintenance" is a term describing the sharing of Debian
+package maintenance duties by several people. This collaboration is
+almost always a good idea, since it generally results in higher quality and
+faster bug fix turnaround time. It is strongly recommended that
+packages in which a priority of <tt>Standard</tt> or which are part of
+the base set have co-maintainers.</p>
<p>
-Here's a list of steps that you may follow to handle a bug report:
-<enumlist>
- <item>
-Decide whether the report corresponds to a real bug or not. Sometimes
-users are just calling a program in the wrong way because they haven't
-read the documentation. If you diagnose this, just close the bug with
-enough information to let the user correct his problem (give pointers
-to the good documentation and so on). If the same report comes up
-again and again you may ask yourself if the documentation is good
-enough or if the program shouldn't detect its misuse in order to
-give an informative error message. This is an issue that may need
-to be brought to the upstream author.
- <p>
-If the bug submitter disagree with your decision to close the bug,
-they may reopen it until you find an agreement on how to handle it.
-If you don't find any, you may want to tag the bug <tt>wontfix</tt>
-to let people know that the bug exists but that it won't be corrected.
-If this situation is unacceptable, you (or the submitter) may want to
-require a decision of the technical committee by reassigning the bug
-to <package>tech-ctte</package> (you may use the clone command of
-the BTS if you wish to keep it reported against your package).
-<!-- FIXME: Follow the procedure described at
- tech-ctte-url (there's no such url yet). -->
- <item>
-If the bug is real but it's caused by another package, just reassign
-the bug the right package. If you don't know which package it should
-be reassigned to, you may either ask for help on &email-debian-devel; or
-reassign it to <package>debian-policy</package> to let them decide which
-package is in fault.
- <p>
-Sometimes you also have to adjust the severity of the bug so that it
-matches our definition of the severity. That's because people tend to
-inflate the severity of bugs to make sure their bugs are fixed quickly.
-Some bugs may even be dropped to wishlist severity when the requested
-change is just cosmetic.
- <item>
-The bug submitter may have forgotten to provide some information, in that
-case you have to ask him the information required. You may use the
-<tt>moreinfo</tt> tag to mark the bug as such. Moreover if you can't
-reproduce the bug, you tag it <tt>unreproducible</tt>. Anyone who
-can reproduce the bug is then invited to provide more information
-on how to reproduce it. After a few months, if this information has not
-been sent by someone, the bug may be closed.
- <item>
-If the bug is related to the packaging, you just fix it. If you are not
-able to fix it yourself, then tag the bug as <tt>help</tt>. You can
-also ask for help on &email-debian-devel; or &email-debian-qa;. If it's an
-upstream problem, you have to forward it to the upstream author.
-Forwarding a bug is not enough, you have to check at each release if
-the bug has been fixed or not. If it has, you just close it, otherwise
-you have to remind the author about it. If you have the required skills
-you can prepare a patch that fixes the bug and that you send at the
-same time to the author. Make sure to send the patch in the BTS and to
-tag the bug as <tt>patch</tt>.
- <item>
-If you have fixed a bug in your local copy, or if a fix has been
-committed to the CVS repository, you may tag the bug as
-<tt>pending</tt> to let people know that the bug is corrected and that
-it will be closed with the next upload (add the <tt>closes:</tt> in
-the <file>changelog</file>). This is particularly useful if you
-are several developers working on the same package.
- <item>
-Once a corrected package is available in the <em>unstable</em>
-distribution, you can close the bug. This can be done automatically,
-read <ref id="upload-bugfix">.
-</enumlist>
+Generally there is a primary maintainer and one or more
+co-maintainers. The primary maintainer is the whose name is listed in
+the <tt>Maintainer</tt> field of the <file>debian/control</file> file.
+Co-maintainers are all the other maintainers.</p>
+ <p>
+In its most basic form, the process of adding a new co-maintainer is
+quite easy:<list>
+ <item>
+ <p>
+Setup the co-maintainer with access to the sources you build the
+package from. Generally this implies you are using a network-capable
+version control system, such as <prgn>CVS</prgn> or
+<prgn>Subversion</prgn>.</p>
+ </item>
+ <item>
+ <p>
+Add the co-maintainer's correct maintainer name and address to the
+<tt>Uploaders</tt> field in the global part of the
+<file>debian/control</file> file.

+Uploaders: John Buzz <jbuzz@debian.org>, Adam Rex <arex@debian.org>

+ <heading>Best Packaging Practices</heading>
+ <p>
+Debian's quality is largely due to the <url id="&url-debian-policy;"
+name="Debian Policy">, which defines explicit baseline requirements
+which all Debian packages must fulfill. Yet there is also a shared
+history of experience which goes beyond the Debian Policy, an
+accumulation of years of experience in packaging. Many very
+talented people have created great tools, tools which help you, the
+Debian maintainer, create and maintain excellent packages.
+ <p>
+This chapter provides some best practices for Debian developers. All
+recommendations are merely that, and are not requirements or policy.
+These are just some subjective hints, advice and pointers collected
+from Debian developers. Feel free to pick and choose whatever works
+best for you.
+
+ <sect id="bpp-debian-rules">
+ <heading>Best practices for <file>debian/rules</file></heading>
+ <p>
+The following recommendations apply to the <file>debian/rules</file>
+file. Since <file>debian/rules</file> controls the build process and
+selects the files which go into the package (directly or indirectly),
+it's usually the file maintainers spend the most time on.
+
+ <sect1 id="helper-scripts">Helper scripts
<p>
-If you fix a bug in your packages, it is your responsibility as the
-package maintainer to close the bug when it has been fixed. However,
-you should not close the bug until the package which fixes the bug has
-been accepted into the Debian archive. Therefore, once you get
-notification that your updated package has been installed into the
-archive, you can and should close the bug in the BTS.
+The rationale for using helper scripts in <file>debian/rules</file> is
+that lets maintainers use and share common logic among many packages.
+Take for instance the question of installing menu entries: you need to
+put the file into <file>/usr/lib/menu</file>, and add commands to the
+maintainer scripts to register and unregister the menu entries. Since
+this is a very common thing for packages to do, why should each
+maintainer rewrite all this on their own, sometimes with bugs? Also,
+supposing the menu directory changed, every package would have to be
+changed.
+ <p>
+Helper scripts take care of these issues. Assuming you comply with
+the conventions expected by the helper script, the helper takes care
+of all the details. Changes in policy can be made in the helper
+script, then packages just need to be rebuilt with the new version of
+the helper and no other changes.
+ <p>
+<ref id="tools"> contains a couple of different helpers. The most
+common and best (in our opinion) helper system is
+<package>debhelper</package>. Previous helper systems, such as
+<package>debmake</package>, were "monolithic": you couldn't pick and
+choose which part of the helper you found useful, but had to use the
+helper to do everything. <package>debhelper</package>, however, is a
+number of separate little <prgn>dh_*</prgn> programs. For instance,
+<prgn>dh_installman</prgn> installs and compresses man pages,
+<prgn>dh_installmenu</prgn> installs menu files, and so on. Thus, it
+offers enough flexibility to be able to use the little helper scripts,
+where useful, in conjunction with hand-crafted commands in
+<file>debian/rules</file>.
<p>
-If you are using a new version of <package>dpkg-dev</package> and you do
-your changelog entry properly, the archive maintenance software will close
-the bugs automatically. All you have to do is follow a certain syntax in
-your <file>debian/changelog</file> file:
-<example>
-acme-cannon (3.1415) unstable; urgency=low
-
- * Frobbed with options (closes: Bug#98339)
- * Added safety to prevent operator dismemberment, closes: bug#98765,
- bug#98713, #98714.
- * Added man page. Closes: #98725.
-</example>
+You can get started with <package>debhelper</package> by reading
+<manref name="debhelper" section="1">, and looking at the examples
+that come with the package. <prgn>dh_make</prgn>, from the
+<package>dh-make</package> package (see <ref id="dh-make">), can be
+used to convert a "vanilla" source package to a
+<package>debhelper</package>ized package. This shortcut, though,
+should not convince you that you do not need to bother understanding
+the individual <prgn>dh_*</prgn> helpers. If you are going to use a
+helper, you do need to take the time to learn to use that helper, to
+learn its expectations and behavior.
+ <p>
+Some people feel that vanilla <file>debian/rules</file> files are
+better, since you don't have to learn the intricacies of any helper
+system. This decision is completely up to you. Use what works for
+you. Many examples of vanilla <file>debian/rules</file> files are
+available at <url id="&url-rules-files;">.
+
+
+ <sect1 id="multiple-patches">
+ <heading>Separating your patches into multiple files</heading>
+ <p>
+Big, complex packages may have many bugs that you need to deal with.
+If you correct a number of bug directly in the source, if you're not
+careful, it can get hard to differentiate the various patches that you
+applied. It can get quite messy when you have to update the package
+to a new upstream version which integrates some of the fixes (but not
+all). You can't take the total set of diffs (e.g., from
+<file>.diff.gz</file>) and work out which patch sets to back out as a
+unit as bugs are fixed upstream.
+ <p>
+Unfortunately, the packaging system as such currently doesn't provide for
+separating the patches into several files. Nevertheless, there are ways to
+separate patches: the patch files are shipped within the Debian patch file
+(<file>.diff.gz</file>), usually within the <file>debian/</file> directory.
+The only difference is that they aren't applied immediately by dpkg-source,
+but by the <tt>build</tt> rule of <file>debian/rules</file>. Conversely,
+they are reverted in the <tt>clean</tt> rule.
+ <p>
+<prgn>dbs</prgn> is one of the more popular approaches to this. It does all
+of the above, and provides a facility for creating new and updating old
+patches. See the package <package>dbs</package> for more information and
+<package>hello-dbs</package> for an example.
+ <p>
+<prgn>dpatch</prgn> also provides these facilities, but it's intented to be
+even easier to use. See the package <package>dpatch</package> for
+documentation and examples (in <file>/usr/share/doc/dpatch</file>).
-Technically speaking, the following Perl regular expression is what is
-used:
-<example>
- /closes:\s*(?:bug)?\#\s*\d+(?:,\s*(?:bug)?\#\s*\d+)*/ig
-</example>
-The author prefers the <tt>closes: #<var>XXX</var></tt> syntax, as
-one of the most concise and easiest to integrate with the text of the
-<file>changelog</file>.
+ <sect1 id="multiple-binary">Multiple binary packages
<p>
-If you want to close bugs the old fashioned, manual way, it is usually
-sufficient to mail the <file>.changes</file> file to
-<email>XXX-done@bugs.debian.org</email>, where <var>XXX</var> is your
-bug number.
+A single source package will often build several binary packages,
+either to provide several flavors of the same software (examples are
+the <package>vim-*</package> packages) or to make several small
+packages instead of a big one (e.g., if the user can install only the
+subset she needs, and thus save some disk space).
+ <p>
+The second case can be easily managed in <file>debian/rules</file>.
+You just need to move the appropriate files from the build directory
+into the package's temporary trees. You can do this using
+<prgn>install</prgn> (vanilla approach) or <prgn>dh_install</prgn>
+(from <package>debhelper</package>). Be sure to check the different
+permutations of the various packages, ensuring that you have the
+inter-package dependencies set right in <file>debian/control</file>.
+ <p>
+The first case is a bit more difficult since it involves multiple
+recompiles of the same software but with different configure
+options. The <package>vim</package> is an example of how to manage
+this using an hand-crafted <file>debian/rules</file> file.

+ <sect id="bpp-debian-maint-scripts">
+ <heading>Best practices for maintainer scripts</heading>
+ <p>
+Maintainer scripts include the files <file>debian/postinst</file>,
+<file>debian/preinst</file>, <file>debian/prerm</file> and
+<file>debian/postrm</file>. These scripts take care of any package
+installation or deinstallation setup which isn't handled merely by the
+creation or removal of files and directories. The following
+instructions supplement the <url id="&url-debian-policy;" name="Debian
+Policy">.
+ <p>
+Maintainer scripts must be idempotent. That means that you need to
+make sure nothing bad will happen if the script is called twice where
+it would usually be called once.
+ <p>
+Standard input and output may be redirected (e.g. into pipes) for
+logging purposes, so don't rely on them being a tty.
+ <p>
+All prompting or interactive configuration should be kept to a
+minimum. When it is necessary, you should use the
+<package>debconf</package> package for the interface. Remember that
+prompting in any case can only be in the <tt>configure</tt> stage of
+the <file>postinst</file> script.
+ <p>
+Keep the maintainer scripts as simple as possible. We suggest you use
+pure POSIX shell scripts. Remember, if you do need any bash features,
+the maintainer script must have a bash sh-bang line. POSIX shell or
+Bash are preferred to Perl, since they enable
+<package>debhelper</package> to easily add bits to the scripts.
+ <p>
+If you change your maintainer scripts, be sure to test package
+removal, double installation, and purging. Be sure that a purged
+package is completely gone, that is, it must remove any files created,
+directly or indirectly, in any maintainer script.
+ <p>
+If you need to check for the existence of a command, you should use
+something like
+<example>if [ -x /usr/sbin/install-docs ]; then ...</example>
+
+If you don't wish to hard-code the path of the command in your
+maintainer script, the following POSIX-compliant shell function may
+help:
+&example-pathfind;
- <sect1 id="lintian-reports">Lintian reports
+You can use this function to search <tt>$PATH</tt> for a command name,
+passed as an argument. It returns true (zero) if the command was
+found, and false if not. This is really the most portable way, since
+<tt>command -v</tt>, <prgn>type</prgn>, and <prgn>which</prgn> are not
+POSIX.
<p>
-You should periodically get the new <package>lintian</package> from
-`unstable' and check over all your packages. Alternatively you can
-check for your maintainer email address at the <url id="&url-lintian;"
-name="online lintian report">. That report, which is updated
-automatically, contains <prgn>lintian</prgn> reports against the
-latest version of the distribution (usually from 'unstable') using the
-latest <package>lintian</package>.
+While <prgn>which</prgn> is an acceptable alternative, since
+it is from the required <package>debianutils</package> package, it's
+not on the root partition. That is, it's in <file>/usr/bin</file> rather
+than <file>/bin</file>, so one can't use it in scripts which are run
+before the <file>/usr</file> partition is mounted. Most scripts won't have
+this problem, though.

-<package>debconf</package> can automatically report outdated translations,
-if package maintainers follow some basic guidelines described below.
- <p>
-Translators can use <prgn>debconf-getlang</prgn> (package
-<package>debconf-utils</package>) to write a <file>templates.xx</file>
-file containing both English and localized fields (where <em>xx</em> is
-the language code, may be followed by a country code). This file can be
-put into the <file>debian</file> subdirectory without any change.
- <p>
-When building a binary package, <file>debian/templates.xx</file> files are
-merged along with <file>debian/templates</file> to generate the
-<file>templates</file> file contained in the binary package. This is
-automatically done by <prgn>dh_installdebconf</prgn> (package
-<package>debhelper</package>). If you do not use debhelper, you can
-do the same with <prgn>debconf-mergetemplate</prgn>
-(package <package>debconf-utils</package>).
- <p>
-When the package maintainer needs to update the templates file, they only

+ <heading>Handling debconf translations</heading>
+ <p>
+Like porters, translators have a difficult task. They work on many
+packages and must collaborate with many different
+maintainers. Moreover, most of the time, they are not native English
+speakers, so you may need to be particularly patient with them.
+ <p>
+The goal of <package>debconf</package> was to make packages
+configuration easier for maintainers and for users. Originally,
+translation of debconf templates was handled with
+<prgn>debconf-mergetemplate</prgn>. However, that technique is now
+deprecated; the best way to accomplish <package>debconf</package>
+internationalization is by using the <package>po-debconf</package>
+package. This method is easier both for maintainer and translators;
+transition scripts are provided.
+ <p>
+Using <package>po-debconf</package>, the translation is stored in
+<file>po</file> files (drawing from <prgn>gettext</prgn> translation
+techniques). Special template files contain the original messages and
+mark which fields are translatable. When you change the value of a
+translatable field, by calling <prgn>debconf-updatepo</prgn>, the
+translation is marked as needing attention from the translators. Then,
+at build time, the <prgn>dh_installdebconf</prgn> program takes care
+of all the needed magic to add the template along with the up-to-date
+translations into the binary packages. Refer to the <manref

+ <p>
+Internationalizing documentation is crucial for users, but a lot of
+labor. There's no way to eliminate all that work, but you can make things
+easier for translators.
+ <p>
+If you maintain documentation of any size, its easier for translators
+if they have access to a source control system. That lets translators
+see the differences between two versions of the documentation, so, for
+instance, they can see what needs to be retranslated. It is
+recommended that the translated documentation maintain a note about
+what source control revision the translation is based on. An
+interesting system is provided by <url id="&url-i18n-doc-check;"
+name="doc-check"> in the <package>boot-floppies</package> package,
+which shows an overview of the translation status for any given
+language, using structured comments for the current revision of the
+file to be translated and, for a translated file, the revision of the
+original file the translation is based on. You might wish to adapt
+and provide that in your CVS area.
+ <p>
+If you maintain XML or SGML documentation, we suggest that you isolate
+any language-independent information and define those as entities in a
+separate file which is included by all the different
+translations. This makes it much easier, for instance, to keep URLs
+up-to-date across multiple files.

+If you notice that a package is lacking maintenance, you should
+make sure that the maintainer is active and will continue to work on
+their packages. It is possible that they are not active any more, but
+haven't registered out of the system, so to speak. On the other hand,
+it is also possible that they just need a reminder.
+ <p>
+The first step is to politely contact the maintainer, and wait for a
+response, for a reasonable time. It is quite hard to define "reasonable
+time", but it is important to take into account that real life is sometimes
+very hectic. One way to handle this would be send a reminder after two
+weeks.
+ <p>
+If the maintainer doesn't reply within four weeks (a month), one can
+assume that a response will probably not happen. If that happens, you
+should investigate further, and try to gather as much useful information
+about the maintainer in question as possible. This includes:
+ <p>
+ <list>
+ <item>The "echelon" information available through the
+ <url id="&url-debian-db;" name="developers' LDAP database">,
+ which indicates when's the last time a developer has posted to
+ a Debian mailing list. (This includes uploads via
+ debian-*-changes lists.) Also, remember to check whether the
+ maintainer is marked as "on vacation" in the database.
+
+ <item>The number of packages this maintainer is responsible for,
+ and the condition of those packages. In particular, are there
+ any RC bugs that have been open for ages? Furthermore, how
+ many bugs are there in general? Another important piece of
+ information is whether the packages have been NMUed, and if
+ so, by whom?
+
+ <item>Is there any activity of the maintainer outside of Debian?
+ For example, they might have posted something recently to
+ non-Debian mailing lists or news groups.
+ </list>
+ <p>
+One big problem are packages which were sponsored -- the maintainer is not
+an official Debian developer. The echelon information is not available for
+sponsored people, for example, so you need to find and contact the Debian
+developer who has actually uploaded the package. Given that they signed the
+package, they're responsible for the upload anyhow, and should know what
+happened to the person they sponsored.
+ <p>
+It is also allowed to post a query to &email-debian-devel;, asking if anyone
+is aware of the whereabouts of the missing maintainer.
+ <p>
+Once you have gathered all of this, you can contact &email-debian-qa;.
+People on this alias will use the information you provided in order to
+decide how to proceed. For example, they might orphan one or all of the
+packages of the maintainer. If a packages has been NMUed, they might prefer
+to contact the NMUer before orphaning the package -- perhaps the person who
+has done the NMU is interested in the package.
+ <p>
+One last word: please remember to be polite. We are all volunteers and
+cannot dedicate all of our time to Debian. Also, you are not aware of the
+circumstances of the person who is involved. Perhaps they might be
+seriously ill or might even had died -- you do not know who may be on the
+receiving side -- imagine how a relative will feel if they read the e-mail
+of the deceased and find a very impolite, angry and accusing message!)
+ <p>
+On the other hand, although we are volunteers, we do have a responsibility.
+So you can stress the importance of the greater good -- if a maintainer does
+not have the time or interest anymore, they should "let go" and give the
