      <para>Welcome, committer, to the FreeBSD development
	team!</para>

      <para>The following docs are provided to orient you on doing CVS
	operations on the FreeBSD central repository machine.  A basic

    <para>It is required that you use &man.ssh.1; or &man.telnet.1;
      with Kerberos 5 to connect to the repository hosts.  These are
      generally more secure than plain &man.telnet.1; or
      &man.rlogin.1; since credential negotiation will always be
      encrypted.  All traffic is encrypted by default with &man.ssh.1;.
      With utilities like &man.ssh-agent.1; and &man.scp.1; also
      available, &man.ssh.1; is also far more convenient.  If you do
      not know anything about &man.ssh.1;, please see
      <xref linkend="ssh.guide">.</para>
  </sect1>

  <sect1 id="cvs.operations">
    <title>CVS Operations</title>

    <para>CVS operations are usually done by logging into
      <hostid>freefall</hostid>, making sure the
      <envar>CVSROOT</envar> environment variable is set to
      <filename>/home/ncvs</filename>, and then doing the appropriate
      check-out/check-in operations.  If you wish to add
      something which is wholly new (like new ports, contrib-ified
      sources, etc), a script called <quote>easy-import</quote> is
      also provided for making the process easier.  It automatically
      adds the new module entry, does the appropriate thing with
      <command>cvs import</command>, etc. &ndash; just run it without
      arguments and it will prompt you for everything it needs to
      know.</para>

    <para>If you are familiar with remote CVS and consider yourself
      pretty studly with CVS in general, you can also do CVS
      operations directly from your own machine and local working
      sources. Just remember to set <envar>CVS_RSH</envar> to
      <wordasword>ssh</wordasword> so that you are using a relatively
      secure and reliable transport.  If you have no idea what any of
      the above even means, on the other hand, then please stick with
      logging into <hostid>freefall</hostid> and applying your diffs
      with &man.patch.1;.</para>

    <para>If you need to use CVS <command>add</command> and
      <command>delete</command> operations in a manner that is
      effectively a <quote>mv</quote> operation, then a repository
      copy is in order rather than your CVS <command>add</command> and
      <command>delete</command>.  In a repository copy, a <link
      linkend="conventions">CVS Meister</link> will copy the file(s)
      to their new name and/or location and let you know when it is
      done.  The purpose of a repository copy is to preserve file
      change history, or logs.  We in the FreeBSD Project greatly
      value the change history CVS gives to the project.</para>
  </sect1>

  <sect1 id="conventions">
    <title>Conventions and Traditions</title>

    <para>The CVS Repository Meisters (Peter Wemm and John Polstra)
      are the <quote>owners</quote> of the CVS repository and
      responsible for any and <emphasis>all</emphasis> direct
      modification of it for the purposes of cleanup or fixing some
      grievous abuse of CVS by a committer.  No one else should
      attempt to touch the repository directly.  Should you cause some
      repository accident, say a bad cvs import or tag operation, do
      <emphasis role="bold">not</emphasis> attempt to fix it yourself!
      Mail or call John or Peter immediately and report the problem to
      one of them instead.  The only ones allowed to directly fiddle
      the repository bits are the repomeisters.  Satoshi Asami is also a
      repomeister for the <filename>ports/</filename> portion of the
      tree.  Mark Murray is the repomeister for the International
      Crypto Repository in South Africa.</para>

    <para>If you are a new committer, your very first commit should be
      to add yourself to the developer's section (28.2) of the
      Handbook and remove yourself from the Additional Contributors section
      (19.6).  Figuring out how to check the handbook out and add an
      entry for yourself is relatively easy but still remains a good
      first test of your CVS skills.  If you can handle that one,
      you are probably going to be ok.</para>

    <para>Your second commit should be to add an entry for yourself to
      <filename>www/en/news/newsflash.sgml</filename>.  Look for the other
      entries that look like <quote>A new committer</quote> and follow the
      format.</para>

    <para>Your next step should be to introduce yourself to the other
      committers, otherwise no one will have any idea who you are or
      what you are working on.  You do not have to write a comprehensive
      biography, just write a paragraph or two about who you are and
      what you plan to be working on as a committer in FreeBSD.  Email
      this to <email>cvs-committers@FreeBSD.org</email> and you will be on
      your way!</para>

    <para>Also, be sure to log into <hostid>hub.FreeBSD.org</hostid>
      and create a
      <filename>/var/forward/<replaceable>user</replaceable></filename>
      (where <replaceable>user</replaceable> is your username) file
      containing the e-mail address where you want mail addressed
      to <replaceable>yourusername</replaceable>@FreeBSD.org
      to be forwarded.  This includes all of the commit messages as
      well as any other mail addressed to
      <email>cvs-committers@FreeBSD.org</email>.  Really large
      mailboxes which have taken up permanent residence on
      <hostid>hub</hostid> often get <quote>accidently</quote>
      truncated without warning, so forward it or read it and you will
      not lose it.</para>

    <para>All new committers also have a mentor assigned to them for
      the first few months.  Your mentor is more or less responsible for
      explaining anything which is confusing to you and is also
      responsible for your actions during this initial period.  If you
      make a bogus commit, it is only going to embarrass your mentor
      and you should probably make it a policy to pass at least your
      first few commits by your mentor before committing it to the
      repository.</para>

    <para>All commits should go to <literal>-CURRENT</literal> first
      before being merged to <literal>-STABLE</literal>.  No major new
      features or high-risk modifications should be made to the
      <literal>-STABLE</literal> branch.</para>
  </sect1>

  <sect1 id="developer.relations">
    <title>Developer Relations</title>

    <para>If you are working directly on your own code or on code
      which is already well established as your responsibility, then
      there is probably little need to check with other committers
      before jumping in with a commit.  If you see a bug in an area of
      the system which is clearly orphaned (and there are a few such
      areas, to our shame), the same applies.  If, however, you are
      about to modify something which is clearly being actively
      maintained by someone else (and it is only by watching the
      <literal>cvs-committers</literal> mailing list that you can
      really get a feel for just what is and is not) then consider
      sending the change to them instead, just as you would have
      before becoming a committer.  For ports, you should contact the
      listed <makevar>MAINTAINER</makevar> in the
      <filename>Makefile</filename>.  For other parts of the
      repository, if you are unsure who the active maintainer might
      be, it may help to scan the output of <command>cvs log</command>
      to see who has committed changes in the past.  &a.fenner; has
      written a nice shell script that can help determine who the
      active maintainer might be.  It lists each person who has
      committed to a given file along with the number of commits each
      person has made.  It can be found on <hostid>freefall</hostid>
      at <filename>~fenner/bin/whodid</filename>.  If your queries go
      unanswered or the committer otherwise indicates a lack of
      proprietary interest in the area affected, go ahead and commit
      it.</para>

    <para>If you are at all unsure about a commit for any reason in
      general, have it reviewed by <literal>-hackers</literal> first
      before committing.  Better to have it flamed then and there
      rather than when it is part of the CVS repository.  If you do
      happen to commit something which results in controversy
      erupting, you may also wish to consider backing the change out
      again until the matter is settled.  Remember &ndash; with CVS we
      can always change it back.</para>

  <sect1 id="gnats">
    <title>GNATS</title>

    <para>The FreeBSD Project utilizes
      <application>GNATS</application> for tracking bugs and change
      requests.  Be sure that if you commit a fix or suggestion found
      in a <application>GNATS</application> PR, you use
      <command>edit-pr <replaceable>pr-number</replaceable></command>
      on <hostid>freefall</hostid> to close it.  It is also considered
      nice if you take time to close any PRs associated with your
      commits, if appropriate.  Your can also make use of

	<para>If you do not wish to to type your password in every

    </orderedlist>

    <para>As noted, breaking some of these rules can be grounds for
      suspension or, upon repeated offense, permanent removal of
      commit privileges.  Three or more members of core, or the
      Principal Architect and another member of core acting in unison,
      have the power to temporarily suspend commit privileges until
      <literal>-core</literal> as a whole has the chance to review the
      issue.  In case of an <quote>emergency</quote> (a committer
      doing damage to the repository), a temporary suspension may also
      be done by the repository meisters or any other member of core
      who may happen to be awake at the time.  Only core as a whole
      has the authority to suspend commit privileges for any
      significant length of time or to remove them permanently, the
      latter generally only being done after consultation with
      committers.  This rule does not exist to set core up as a bunch
      of cruel dictators who can dispose of committers as casually as
      empty soda cans, but to give the project a kind of safety fuse.
      If someone is seriously out of control, it's important to be
      able to deal with this immediately rather than be paralyzed by
      debate.  In all cases, a committer whose privileges are
      suspended or revoked is entitled to a <quote>hearing</quote>,
      the total duration of the suspension being determined at that
      time.  A committer whose privileges are suspended may also
      request a review of the decision after 30 days and every 30 days
      thereafter (unless the total suspension period is less than 30
      days).  A committer whose privileges have been revoked entirely
      may request a review after a period of 6 months have elapsed.
      This review policy is <emphasis>strictly informal</emphasis>
      and, in all cases, core reserves the right to either act on or
      disregard requests for review if they feel their original
      decision to be the right one.</para>
    
    <para>In all other aspects of project operation, core is a subset
      of committers and is bound by the <emphasis>same
      rules</emphasis>.  Just because someone is in core doesn't mean
      that they have special dispensation to step outside of any of
      the lines painted here; core's <quote>special powers</quote>
      only kick in when it acts as a group, not on an individual
      basis.  As individuals, we are all committers first and core
      second.</para>

	  <para>Respect other committers.</para>

	  <para>This means that you need to treat other committers as

	    occasional attempts to prove the contrary, one doesn't get
	    into committers by being stupid and nothing rankles more
	    than being treated that way by one of your peers.  Whether
	    we always feel respect for one another or not (and
	    everyone has off days), we still have to

	    your side of the argument is correct, don't just blow off

	  </question>

	  <answer>
	    <para>First, please read the section about repository
	      copy.</para>

	    <para>The easiest way to import a new port is to use the
	      <command>easy-import</command> script on
	      <hostid>freefall</hostid>.  It will ask you some
	      questions and import the port in the directory you
	      specify.  It will also add an entry to the
	      <filename>CVSROOT/modules</filename> file.  It was
	      written by &a.joerg; so please send mail to him if you
	      have questions about
	      <command>easy-import</command>.</para>

	    <para>One thing it will not do for you is add the port to
	      the parent (category) <filename>Makefile</filename>.
	      You have to do that yourself.</para>

	<qandaentry>
	  <question>
	    <para>Any other things I need to know when I import a new
	      port?</para>
	  </question>

	  <answer>
	    <para>Check the port, preferably to make sure it compiles
	      and packages correctly.  This is the recommended
	      sequence:</para>

	    <screen>&prompt.user; <userinput>make install</userinput>
&prompt.user; <userinput>make package</userinput>
&prompt.user; <userinput>make deinstall</userinput>
&prompt.user; <userinput>pkg_add <replaceable>package you built above</replaceable></userinput>
&prompt.user; <userinput>make deinstall</userinput>
&prompt.user; <userinput>make reinstall</userinput>
&prompt.user; <userinput>make package</userinput>
	    </screen>

	    <para>The Handbook's
	      <ulink url="../handbook/porting.html">porting
	      section</ulink> contains more detailed
	      instructions.</para>

	    <para>Use &man.portlint.1; to check the syntax of the port.
	      You don't necessarily have to eliminate all warnings but
	      make sure you have fixed the simple ones.</para>

	    <para>If the port came from a submitter who has not
	      contributed to the project before, add that person's
	      name to the Handbook's <citetitle
	      pubwork="section">Additional Contributors</citetitle>
	      section.</para>

	    <para>Close the PR if the port came in as a PR.  To close
	      a PR, just do 
	      <userinput>edit-pr <replaceable>PR#</replaceable></userinput>
	      on <hostid>freefall</hostid> and change the
	      <varname>state</varname> from <constant>open</constant>
	      to <constant>closed</constant>.  You will be asked to

	<title>Repository Copies</title>

	<qandaentry>
	  <question>
	    <para>When do we need a repository copy?</para>
	  </question>

	  <answer>
	    <para>When you want to import a port that is related to
	      any port that is already in the tree in a separate
	      directory, please send mail to the ports manager asking
	      about it.  Here <wordasword>related</wordasword> means
	      it is a different version or a slightly modified
	      version.  Examples are
	      <filename>print/ghostscript*</filename> (different
	      versions) and <filename>x11-wm/windowmaker*</filename>
	      (English-only and internationalized version).</para>

	    <para>Another example is when a port is moved from one
	      subdirectory to another, or when you want to change the
	      name of a directory because the author(s) renamed their
	      software even though it is a
	      descendant of a port already in a tree.</para>

	  <answer>
	    <para>When there is no history to preserve.  If a port is
	      imported into a wrong category and is moved immediately,

	  <answer>
	    <para>No.  The ports manager will regenerate the

	  <answer>
	    <para>Any file directly under <filename>ports/</filename>, or
	      any file under a subdirectory that starts with an

	      <filename>Tools/</filename>, etc.).  In particular, the

	      commit changes to those files unless you want to face his

	<question>
	  <para>Why are trivial or cosmetic changes to files on a vendor
	    branch a bad idea?</para>
	</question>

	<answer>
	  <para>The RCS file format is quite braindead and certain
	    operations to achieve things for CVS are hideously
	    expensive for the repository.  Making changes to files on
	    a vendor branch, thereby pulling the file off that branch,
	    is one example of this.</para>

	  <para>Suppose you have a file which was first imported on a
	    vendor branch, and was then re-imported three times (still
	    on the vendor branch) as the vendor makes updates to the
	    file.</para>

	  <segmentedlist>
	    <seglistitem>
	      <seg>1.1.1.1</seg>
	      <seg>vendor import</seg>
	    </seglistitem>

	    <seglistitem>
	      <seg>1.1.1.2</seg>
	      <seg>vendor import, +1000, -500 lines</seg>
	    </seglistitem>

	    <seglistitem>
	      <seg>1.1.1.3</seg>
	      <seg>vendor import, +2000, -500 lines</seg>
	    </seglistitem>

	    <seglistitem>
	      <seg>1.1.1.4</seg>
	      <seg>vendor import, +1000, -1000 lines</seg>
	    </seglistitem>
	  </segmentedlist>

	  <para>Now suppose that one of the FreeBSD committers makes a
	    one line change to this file, causing it to go to version
	    1.2.  This causes it to leave the branch, resulting in
	    4,001 lines being added to the file's history, and 2,001
	    lines being deleted.</para>

	  <para>This is because the 1.2 delta is stored relative to
	    1.1.1.1, <emphasis>not</emphasis> 1.1.1.4, and so the
	    entire vendor history is duplicated in the 1.2 delta.
	    Now, repeat this for 2000 files in a large directory, it
	    adds up a lot.</para>

	  <para><emphasis>This</emphasis> is why we have such
	    <quote>hands off</quote> policies for
	    <filename>src/contrib</filename> and other things that
	    track the vendor releases.  This is why <quote>typo
	    fixes</quote> in man pages and spelling
	    <quote>corrections</quote> are so strongly discouraged for
	    vendor code.</para>
