481 <p>It is highly functional. However, not all methods are implemented,
482 and for those methods that are implemented,
483 not all switches are implemented.</p>
484 </div>
485 <div class="paragraph">
486 <p>Testing has been done using both the CLI CVS client, and the Eclipse CVS
487 plugin. Most functionality works fine with both of these clients.</p>

565 <p>Note: Some inetd servers let you specify the name of the executable
566 independently of the value of argv[0] (i.e. the name the program assumes

576 <p>Only anonymous access is provided by pserver by default. To commit you
577 will have to create pserver accounts, simply add a gitcvs.authdb
578 setting in the config file of the repositories you want the cvsserver
579 to allow writes to, for example:</p>

721 <h2 id="dbbackend">DATABASE BACKEND</h2>
722 <div class="sectionbody">
723 <div class="paragraph">
724 <p><em>git-cvsserver</em> uses one database per Git head (i.e. CVS module) to
725 store information about the repository to maintain consistent
726 CVS revision numbers. The database needs to be
727 updated (i.e. written to) after every commit.</p>
728 </div>
729 <div class="paragraph">
730 <p>If the commit is done directly by using <code>git</code> (as opposed to
731 using <em>git-cvsserver</em>) the update will need to happen on the
732 next repository access by <em>git-cvsserver</em>, independent of
733 access method and requested operation.</p>
734 </div>
735 <div class="paragraph">
736 <p>That means that even if you offer only read access (e.g. by using
737 the pserver method), <em>git-cvsserver</em> should have write access to
738 the database to work reliably (otherwise you need to make sure
739 that the database is up to date any time <em>git-cvsserver</em> is executed).</p>
740 </div>
741 <div class="paragraph">
742 <p>By default it uses SQLite databases in the Git directory, named
743 <code>gitcvs.</code><em>&lt;module-name&gt;</em><code>.sqlite</code>. Note that the SQLite backend creates
744 temporary files in the same directory as the database file on
745 write so it might not be enough to grant the users using
746 <em>git-cvsserver</em> write access to the database file without granting
747 them write access to the directory, too.</p>
748 </div>
749 <div class="paragraph">
750 <p>The database cannot be reliably regenerated in a
751 consistent form after the branch it is tracking has changed.
752 Example: For merged branches, <em>git-cvsserver</em> only tracks
753 one branch of development, and after a <em>git merge</em> an
754 incrementally updated database may track a different branch
755 than a database regenerated from scratch, causing inconsistent
756 CVS revision numbers. <code>git-cvsserver</code> has no way of knowing which
757 branch it would have picked if it had been run incrementally
758 pre-merge. So if you have to fully or partially (from old
759 backup) regenerate the database, you should be suspicious
760 of pre-existing CVS sandboxes.</p>

947 checkout, diff, status, update, log, add, remove, commit.</p>
948 </div>
949 <div class="paragraph">
950 <p>Most CVS command arguments that read CVS tags or revision numbers
951 (typically -r) work, and also support any git refspec
952 (tag, branch, commit ID, etc).
953 However, CVS revision numbers for non-default branches are not well
954 emulated, and cvs log does not show tags or branches at
955 all. (Non-main-branch CVS revision numbers superficially resemble CVS
956 revision numbers, but they actually encode a git commit ID directly,
957 rather than represent the number of revisions since the branch point.)</p>
958 </div>
959 <div class="paragraph">
960 <p>Note that there are two ways to checkout a particular branch.
961 As described elsewhere on this page, the "module" parameter
962 of cvs checkout is interpreted as a branch name, and it becomes
963 the main branch. It remains the main branch for a given sandbox
964 even if you temporarily make another branch sticky with
965 cvs update -r. Alternatively, the -r argument can indicate
966 some other branch to actually checkout, even though the module
967 is still the "main" branch. Tradeoffs (as currently
968 implemented): Each new "module" creates a new database on disk with
969 a history for the given module, and after the database is created,
970 operations against that main branch are fast. Or alternatively,
971 -r doesn&#8217;t take any extra disk space, but may be significantly slower for
972 many operations, like cvs update.</p>
973 </div>
974 <div class="paragraph">
975 <p>If you want to refer to a git refspec that has characters that are
976 not allowed by CVS, you have two options. First, it may just work
977 to supply the git refspec directly to the appropriate CVS -r argument;
978 some CVS clients don&#8217;t seem to do much sanity checking of the argument.
979 Second, if that fails, you can use a special character escape mechanism
980 that only uses characters that are valid in CVS tags. A sequence
981 of 4 or 5 characters of the form (underscore ("_"), dash ("-"),
982 one or two characters, and dash ("-")) can encode various characters based
983 on the one or two letters: "s" for slash ("/"), "p" for
984 period ("."), "u" for underscore ("_"), or two hexadecimal digits
985 for any byte value at all (typically an ASCII number, or perhaps a part
986 of a UTF-8 encoded character).</p>
987 </div>
988 <div class="paragraph">
989 <p>Legacy monitoring operations are not supported (edit, watch and related).

993 <h3 id="_crlf_line_ending_conversions">CRLF Line Ending Conversions</h3>
994 <div class="paragraph">
995 <p>By default the server leaves the <code>-k</code> mode blank for all files,
996 which causes the CVS client to treat them as a text files, subject
997 to end-of-line conversion on some platforms.</p>
998 </div>
999 <div class="paragraph">
1000 <p>You can make the server use the end-of-line conversion attributes to
1001 set the <code>-k</code> modes for files by setting the <code>gitcvs.usecrlfattr</code>
1002 config variable. See <a href="gitattributes.html">gitattributes(5)</a> for more information
1003 about end-of-line conversion.</p>
1004 </div>
1005 <div class="paragraph">
1006 <p>Alternatively, if <code>gitcvs.usecrlfattr</code> config is not enabled
1007 or the attributes do not allow automatic detection for a filename, then
1008 the server uses the <code>gitcvs.allBinary</code> config for the default setting.
1009 If <code>gitcvs.allBinary</code> is set, then file not otherwise
1010 specified will default to <em>-kb</em> mode. Otherwise the <code>-k</code> mode
1011 is left blank. But if <code>gitcvs.allBinary</code> is set to "guess", then
1012 the correct <code>-k</code> mode will be guessed based on the contents of
1013 the file.</p>
1014 </div>
1015 <div class="paragraph">
1016 <p>For best consistency with <em>cvs</em>, it is probably best to override the
