Import CVS-1.6.3-951211.. Basically, this is the cvs-1.6.2 release
plus a couple of minor changes..
Some highlights of the new stuff that was not in the old version:
- remote access support.. full checkout/commit/log/etc..
- much improved dead file support..
- speed improvements
- better $CVSROOT handling
- $Name$ support
- support for a "cvsadmin" group to cut down rampant use of "cvs admin -o"
- safer setuid/setgid support
- many bugs fixed.. :-)
- probably some new ones.. :-(
- more that I cannot remember offhand..

There are a number of systems + that now use /var/tmp. These should probably be detected by autoconf. + + 2) The server deals rather ungracefully with the tmp directory + becoming full. + + 3) There's some oddness with relative paths in Repository files that + causes the directory prefix to be added twice; e.g. if I have CVSROOT + set to `machine:/this/dir', and I try to update in a directory whose + Repository file says `src/bin', the server looks in + `/this/dir/machine:/this/dir/src/bin'. + +* From: "Charles M.

The default prefix + value is "/usr/local", with binaries in sub-directory "bin", manual + pages in sub-directory "man", and libraries in sub-directory "lib". + + This release of CVS also requires RCS commands to be installed in + the user's PATH (or a path you have configured in src/options.h). + If you don't have RCS, you will need to get it from GNU as well. It + is best to get the version 5.7 (or later) version of RCS, available + from prep.ai.mit.edu in the file pub/gnu/rcs-5.7.tar.gz. It is best + (although not essential) to avoid RCS versions 5.6.[5-7] beta + because the rcsmerge therein defaults to -A instead of -E which + affects the way CVS handles conflicts (this is fixed in RCS 5.6.8 + and RCS 5.7). + + Along with RCS, you will want to run GNU diffutils. This will allow + revision control of files with binary data (a real nice feature). + You will need at least version 1.15 of GNU diff for this to work. + The current version of GNU diffutils is 2.7, and it is also + available from prep.ai.mit.edu in the file pub/gnu/diffutils-2.7.tar.gz. + + WARNING: Be sure that you (have) configure(d) RCS to work correctly + with GNU diff to avoid other configuration problems. + + Configure will attempt to discern the location of your most capable + version of diff, and tries to find the GNU Diffutils version first. + You can explicitly tell configure to use the diffutils that's + installed in the same place you intend to install CVS: + + $ ./configure --with-diffutils + + Or, if you've installed it somewhere else, you can give configure + the full pathname: + + $ ./configure --with-diffutils=/usr/gnu/bin/diff + + Configure will also try to find a version of grep that supports the + '-s' option, and tries to find the GNU Grep version first. You can + similarly tell it where to find GNU Grep: + + $ ./configure --with-gnugrep + $ ./configure --with-gnugrep=/usr/gnu/bin/grep + + If you are using the remote client, you will need a version of patch + which understands unidiffs (such as any recent version of GNU + patch). Configure does not yet check to see if you've got this, so + be careful! + + NOTE: The configure program will cache the results of the previous + configure execution. If you need to re-run configure from scratch, you + may need to run "make distclean" first to remove the cached + configuration information. + + Try './configure --help' for further information on its usage. + + NOTE ON CVS's USE OF NDBM: + + By default, CVS uses some built-in ndbm emulation code to allow + CVS to work in a heterogeneous environment. However, if you have + a very large modules database, this may not work well. You will + need to edit src/options.h to turn off the MY_NDBM #define and + re-run configure. If you do this, the following comments apply. + If not, you may safely skip these comments. + + If you configure CVS to use the real ndbm(3) libraries and + you do not have them installed in a "normal" place, you will + probably want to get the GNU version of ndbm (gdbm) and install + that before running the CVS configure script. Be aware that the + GDBM 1.5 release does NOT install the <ndbm.h> header file included + with the release automatically. You may have to install it by hand. + + If you configure CVS to use the ndbm(3) libraries, you cannot + compile CVS with GNU cc (gcc) on Sun-4 SPARC systems. However, gcc + 2.0 may have fixed this limitation if -fpcc-struct-return is + defined. When using gcc on other systems to compile CVS, you *may* + need to specify the -fpcc-struct-return option to gcc (you will + *know* you have to if "cvs checkout" core dumps in some ndbm + function). You can do this as follows: + + $ CC='gcc -fpcc-struct-return' ./configure + + for sh, bash, and ksh users and: + + % setenv CC 'gcc -fpcc-struct-return' + % ./configure + + for csh and tcsh users. + + END OF NOTE FOR NDBM GUNK. + +2) Edit src/options.h. Appropriate things to look at may be the + invocation locations of programs like DIFF, GREP, RM, and SORT. + Also glance at the default values for the environment variables + that CVS uses, in particular, the RCSBIN variable, which holds the + path to where the RCS programs live on your system. The + likelihood is that you don't have to change anything here, except + perhaps adding the -a option to DIFF if you are using GNU diff. + +3) Try to build it: + + $ make + + This will (hopefully) make the needed CVS binaries within the "src" + directory. If something fails for your system, using the "cvsbug" + script submit your "config.status" file together with your host + type, operating system and compiler information, make output, and + anything else you think will be helpful. + + You may also wish to validate the correctness of the new binary by + running the regression tests: + + $ make check + + Note that if your /bin/sh doesn't support shell functions, you'll + have to try something like this, where "/bin/sh5" is replaced by the + pathname of a shell which handles normal shell functions: + + $ make SHELL=/bin/sh5 check + + WARNING: This test can take quite a while to run, esp. if your + disks are slow or over-loaded. + + If you receive any un-expected output from the regression tests, + using the "cvsbug" script please submit your "config.status" file, + together with your host type, operating system and compiler + information, the contents of /tmp/cvs-sanity/check.log, and any + "make check" output. + +4) Install the binaries/documentation: + + $ make install + + Depending on your installation's configuration, you may need to be + root to do this. + +5) Take a look at the CVS documentation. + + $ man cvs + + and + + $ info cvs + + See what it can do for you, and if it fits your environment (or can + possibly be made to fit your environment). If things look good, + continue on... + +6) Setup the master source repository. Choose a directory with ample disk + space available for source files. This is where the RCS ",v" files + will be stored. Note that this should be some shared directory for your + site. It should probably be auto-mounted, if you're running NFS. + + Say you choose "/src/master" as the root of your source repository. + Run the "cvsinit" script to help you set it up. It will ask you to + enter the path to your CVSROOT area. You would enter /src/master in + this example. + + $ ./cvsinit + + The cvsinit script will setup a reasonable CVSROOT area to start with. + It is also valuable to folks who already have a CVSROOT area setup from + using earlier releases of CVS. It assumes that you have installed CVS + already (step 4) and that the RCS programs (co and ci) are in your + PATH. There are many ways to customize CVS for your site. Read the + cvs(5) manual page when you get the chance. + +7) Have all users of the CVS system set the CVSROOT environment + variable appropriately to reflect the placement of your source + repository. If the above example is used, the following commands + can be placed in user's ~/.profile, ~/.bash_profile file; or in the + site-wide /etc/profile: + + CVSROOT=/src/master; export CVSROOT + + for sh/bash/ksh users, or place the following commands in the user's + ~/.cshrc, ~/.login, or /etc/chsrc file: + + setenv CVSROOT /src/master + + for csh/tcsh users. If these environment variables are not already set + in your current shell, set them now (or source the login script you + just edited). You will need to have the CVSROOT environment variable + set to continue on to the next step. + +8) It might be a good idea to jump right in and put the CVS distribution + directly under CVS control. From within the top-level directory of the + CVS distribution (the one that contains this README file) do the + following commands: + + $ make distclean + $ cvs import -m 'CVS 1.6 distribution' cvs CVS CVS-1_6 + +9) Having done step 8, one should be able to checkout a fresh copy of the + CVS distribution and hack away at the sources with the following command: + + $ cd + $ cvs checkout cvs + + This will make the directory "cvs" in your current directory and + populate it with the appropriate CVS files and directories. + +10) Remember to edit the modules file manually when sources are checked in + with "cvs import" or "cvs add". A copy of the modules file for editing + can usually be retrieved with the "cvs checkout modules" command, and + definitely with the "cvs checkout CVSROOT" command. See cvs(5). + +11) Read the NEWS file to see what's new. + +12) Hack away. + +------------------------------------------------------------------------------- + +Detailed information about your interaction with "configure": + +The "configure" script and its interaction with its options and the +environment is described here.

This way other developers will be able to access the files in +the repository regardless of the umask of the developer creating them. + +* The command name .cvsrc now matches the official name of the +command, not the one (possibly an alias) by which it was invoked. If +you had previously relied on "cvs di" and "cvs diff" using different +options, instead use a shell function or alias (for example "alias +cvsdi='cvs diff -u'"). + +Changes from 1.5 to 1.6: + +* Del updated the man page to include all of the new features +of CVS 1.6. + +* "cvs tag" now supports a "-r | -D" option for tagging an already +tagged revision / specific revision of a file. + +* There is a "taginfo" file in CVSROOT that supports filtering and +recording of tag operations. + +* Long options support added, including --help and --version options. + +* "cvs release" no longer cares whether or not the directory being +released has an entry in the `modules' file. + +* The modules file now takes a -e option which is used instead of -o +for "cvs export". If your modules file has a -o option which you want +to be used for "cvs export", change it to specify -e as well as -o. + +* "cvs export" now takes a -k option to set RCS keyword expansion. +This way you can export binary files. If you want the old behavior, +you need to specify -kv. + +* "cvs update", "cvs rdiff", "cvs checkout", "cvs import", "cvs +release", "cvs rtag", and "cvs tag" used to take -q and -Q options +after the command name (e.g. "cvs update -q"). This was confusing +because other commands, such as "cvs ci", did not. So the options +after the command name have been removed and you must now specify, for +example, "cvs -q update", which has been supported since CVS 1.3. + +* New "wrappers" feature. This allows you to set a hook which +transforms files on their way in and out of cvs (apparently on the +NeXT there is some particular usefulness in tarring things up in the +repository). It also allows you to declare files as merge-by-copy +which means that instead of trying to merge the file, CVS will merely +copy the new version. There is a CVSROOT/cvswrappers file and an +optionsl ~/.cvswrappers file to support this feature. + +* You can set CVSROOT to user@host:dir, not just host:dir, if your +username on the server host is different than on the client host. + +* VISUAL is accepted as well as EDITOR. + +* $CVSROOT is expanded in *info files. + +Changes from 1.4A2 to 1.5: + +* Remote implementation. This is very helpful when collaborating on a +project with someone across a wide-area network. This release can +also be used locally, like other CVS versions, if you have no need for +remote access. + +Here are some of the features of the remote implementation: +- It uses reliable transport protocols (TCP/IP) for remote repository + access, not NFS. NFS is unusable over long distances (and sometimes + over short distances) +- It transfers only those files that have changed in the repository or + the working directory. To save transmission time, it will transfer + patches when appropriate, and can compress data for transmission. +- The server never holds CVS locks while waiting for a reply from the client; + this makes the system robust when used over flaky networks. + +The remote features are documented in doc/cvsclient.texi in the CVS +distribution, but the main doc file, cvs.texinfo, has not yet been +updated to include the remote features. + +* Death support. See src/README-rm-add for more information on this. + +* Many speedups, especially from jtc@cygnus.com. + +* CVS 1.2 compatibility code has been removed as a speedup. If you +have working directories checked out by CVS 1.2, CVS 1.3 or 1.4A2 will +try to convert them, but CVS 1.5 and later will not (if the working +directory is up to date and contains no extraneous files, you can just +remove it, and then check out a new working directory). Likewise if +your repository contains a CVSROOT.adm directory instead of a CVSROOT +directory, you need to rename it. + +Fri Oct 21 20:58:54 1994 Brian Berliner <berliner@sun.com> + + * Changes between CVS 1.3 and CVS 1.4 Alpha-2 + + * A new program, "cvsbug", is provided to let you send bug reports + directly to the CVS maintainers. Please use it instead of sending + mail to the info-cvs mailing list. If your build fails, you may + have to invoke "cvsbug" directly from the "src" directory as + "src/cvsbug.sh". + + * A new User's Guide and Tutorial, written by Per Cederqvist + <ceder@signum.se> of Signum Support. See the "doc" directory. A + PostScript version is included as "doc/cvs.ps". + + * The Frequesntly Asked Questions file, FAQ, has been added to the + release. Unfortunately, its contents are likely out-of-date. + + * The "cvsinit" shell script is now installed in the $prefix/bin + directory like the other programs. You can now create new + CVS repositories with great ease. + + * Index: lines are now printed on output from 'diff' and 'rdiff', + in order to facilitate application of patches to multiple subdirs. + + * Support for a ~/.cvsrc file, which allows you to specify options + that are always supposed to be given to a specific command. This + feature shows the non-orthogonality of the option set, since while + there may be an option to turn something on, the option to turn + that same thing off may not exist. + + * You can now list subdirectories that you wish to ignore in a + modules listing, such as: + + gcc -a gnu/gcc, !gnu/gcc/testsuites + + which will check out everything underneath gnu/gcc, except + everything underneath gnu/gcc/testsuites. + + * It is now much harder to accidentally overwrite an existing tag + name, since attempting to move a tag name will result in a error, + unless the -F (force) flag is given to the tag subcommands. + + * Better error checking on matching of the repository used to + check code out from against the repository the current cvs + commnands would use. (Thanks to Mark Baushke <mdb@cisco.com>) + + * Better support for sites with multiple CVSROOT repositories has + been contributed. The file "CVS/Root" in your working directory + is created to hold the full path to the CVS repository and a + simple check is made against your current CVSROOT setting. + + * You can now specify an RCS keyword substitution value when you + import files into the repository. + + * Uses a much newer version of Autoconf, and conforms to the GNU + coding standards much more closely. No, it still doesn't have + long option names. + + * Code cleanup. Many passes through gcc -Wall helped to identify + a number of questionable constructs. Most arbitrary length limits + were removed. + + * Profiling to determine bottlenecks helped to identify the best + places to spend time speeding up the code, which was then done. A + number of performance enhancements in filename matching have sped + up checkouts. + + * Many more contributions have been added to the "contrib" + directory. See the README file in that directory for more + information. + + * "cvs commit" will try harder to not change the file's + modification time after the commit. If the file does not change + as a result of the commit operation, CVS will preserve the + original modification time, thus speeding up future make-type + builds. + + * "cvs commit" now includes any removed files in the (optional) + pre-commit checking program that may be invoked. Previously, only + added and modified files were included. + + * It is now possible to commit a file directly onto the trunk at a + specific revision level by doing "cvs commit -r3.0 file.c", where + "3.0" specifies the revision you wish to create. The file must be + up-to-date with the current head of the trunk for this to succeed. + + * "cvs commit" will now function with a pre-commit program that + has arguments specified in the "commitinfo" file. + + * The "mkmodules" program will now look within the + $CVSROOT/CVSROOT/checkoutlist" file for any additional files that + should be automatically checked out within CVSROOT; mkmodules also + tries harder to preserve any execute bits the files may have + originally had. + + * "cvs diff" is much more accurate about its exit status now. It + now returns the maximum exit status of any invoked diff. + + * The "-I !" option is now supported for the import and update + commands correctly. It will properly clear the ignore list now. + + * Some problems with "cvs import" handling of .cvsignore have been + fixed; as well, some rampant recursion problems with import have + also been fixed. + + * "cvs rdiff" (aka "cvs patch") now tries to set the modify time + of any temporary files it uses to match those specified for the + particular revision. This allows a more accurate patch image to + be created. + + * "cvs status" has improved revision descriptions. "Working + revision" is used for the revision of the working file that you + edit directly; "Repository revision" is the revision of the file + with the $CVSROOT source repository. Also, the output is clearer + with regard to sticky and branch revisions. + + * CVS no longer dumps core when given a mixture of directories and + files in sub-directories (as in "cvs ci file1 dir1/file2"). + Instead, arguments are now clumped into their respective directory + and operated on in chunks, together. + + * If the CVSEDITOR environment variable is set, that editor is + used for log messages instead of the EDITOR environment variable. + This makes it easy to substitute intelligent programs to make more + elaborate log messages. Contributed by Mark D Baushke + (mdb@cisco.com). + + * Command argument changes: + cvs: The "-f" option has been added to ignore + the ~/.cvsrc file. + commit: Renamed the "-f logfile" option to the + "-F logfile" option. Added the "-f" + option to force a commit of the specified + files (this disables recursion). + history: Added "-t timezone" option to force any + date-specific output into the specified + timezone. + import: Added "-d" option to use the file's + modification time as the time of the + import. Added "-k sub" option to set the + default RCS keyword substitution mode for + newly-created files. + remove: Added "-f" option to force the file's + automatic removal if it still exists in + the working directory (use with caution). + rtag: Added "-F" option to move the tag if it + already exists -- new default is to NOT + move tags automatically. + tag: Added "-F" option to move the tag if it + already exists -- new default is to NOT + move tags automatically. + +Tue Apr 7 15:55:25 1992 Brian Berliner (berliner at sun.com) + + * Changes between CVS 1.3 Beta-3 and official CVS 1.3! + + * A new shell script is provided, "./cvsinit", which can be run at + install time to help setup your $CVSROOT area. This can greatly + ease your entry into CVS usage. + + * The INSTALL file has been updated to include the machines on + which CVS has compiled successfully. I think CVS 1.3 is finally + portable. Thanks to all the Beta testers! + + * Support for the "editinfo" file was contributed. This file + (located in $CVSROOT/CVSROOT) can be used to specify a special + "editor" to run on a per-directory basis within the repository, + instead of the usual user's editor. As such, it can verify that + the log message entered by the user is of the appropriate form + (contains a bugid and test validation, for example). + + * The manual pages cvs(1) and cvs(5) have been updated. + + * The "mkmodules" command now informs you when your modules file + has duplicate entries. + + * The "add" command now preserves any per-directory sticky tag when + you add a new directory to your checked-out sources. + + * The "admin" command is now a fully recursive interface to the + "rcs" program which operates on your checked-out sources. It no + longer requires you to specify the full path to the RCS file. + + * The per-file sticky tags can now be effectively removed with + "cvs update -A file", even if you had checked out the whole + directory with a per-directory sticky tag. This allows a great + deal of flexibility in managing the revisions that your checked-out + sources are based upon (both per-directory and per-file sticky + tags). + + * The "cvs -n commit" command now works, to show which files are + out-of-date and will cause the real commit to fail, or which files + will fail any pre-commit checks. Also, the "cvs -n import ..." + command will now show you what it would've done without actually + doing it. + + * Doing "cvs commit modules" to checkin the modules file will no + properly run the "mkmodules" program (assuming you have setup your + $CVSROOT/CVSROOT/modules file to do so). + + * The -t option in the modules file (which specifies a program to + run when you do a "cvs rtag" operation on a module) now gets the + symbolic tag as the second argument when invoked. + + * When the source repository is locked by another user, that user's + login name will be displayed as the holder of the lock. + + * Doing "cvs checkout module/file.c" now works even if + module/file.c is in the Attic (has been removed from main-line + development). + + * Doing "cvs commit */Makefile" now works as one would expect. + Rather than trying to commit everything recursively, it will now + commit just the files specified. + + * The "cvs remove" command is now fully recursive. To schedule a + file for removal, all you have to do is "rm file" and "cvs rm". + With no arguments, "cvs rm" will schedule all files that have been + physically removed for removal from the source repository at the + next "cvs commit". + + * The "cvs tag" command now prints "T file" for each file that was + tagged by this invocation and "D file" for each file that had the + tag removed (as with "cvs tag -d"). + + * The -a option has been added to "cvs rtag" to force it to clean + up any old, matching tags for files that have been removed (in the + Attic) that may not have been touched by this tag operation. This + can help keep a consistent view with your tag, even if you re-use + it frequently. + +Sat Feb 29 16:02:05 1992 Brian Berliner (berliner at sun.com) + + * Changes between CVS 1.3 Beta-2 and CVS 1.3 Beta-3 + + * Many portability fixes, thanks to all the Beta testers! With any + luck, this Beta release will compile correctly on most anything. + Hey, what are we without our dreams. + + * CVS finally has support for doing isolated development on a + branch off the current (or previous!) revisions. This is also + extremely nice for generating patches for previously released + software while development is progressing on the next release. + Here's an example of creating a branch to fix a patch with the 2.0 + version of the "foo" module, even though we are already well into + the 3.0 release. Do: + + % cvs rtag -b -rFOO_2_0 FOO_2_0_Patch foo + % cvs checkout -rFOO_2_0_Patch foo + % cd foo + [[ hack away ]] + % cvs commit + + A physical branch will be created in the RCS file only when you + actually commit the change. As such, forking development at some + random point in time is extremely light-weight -- requiring just a + symbolic tag in each file until a commit is done. To fork + development at the currently checked out sources, do: + + % cvs tag -b Personal_Hack + % cvs update -rPersonal_Hack + [[ hack away ]] + % cvs commit + + Now, if you decide you want the changes made in the Personal_Hack + branch to be merged in with other changes made in the main-line + development, you could do: + + % cvs commit # to make Personal_Hack complete + % cvs update -A # to update sources to main-line + % cvs update -jPersonal_Hack # to merge Personal_Hack + + to update your checked-out sources, or: + + % cvs checkout -jPersonal_Hack module + + to checkout a fresh copy. + + To support this notion of forked development, CVS reserves + all even-numbered branches for its own use. In addition, CVS + reserves the ".0" and ".1" branches. So, if you intend to do your + own branches by hand with RCS, you should use odd-numbered branches + starting with ".3", as in "1.1.3", "1.1.5", 1.2.9", .... + + * The "cvs commit" command now supports a fully functional -r + option, allowing you to commit your changes to a specific numeric + revision or symbolic tag with full consistency checks. Numeric + tags are useful for bringing your sources all up to some revision + level: + + % cvs commit -r2.0 + + For symbolic tags, you can only commit to a tag that references a + branch in the RCS file. One created by "cvs rtag -b" or from + "cvs tag -b" is appropriate (see below). + + * Roland Pesch <pesch@cygnus.com> and K. Richard Pixley + <rich@cygnus.com> were kind enough to contribute two new manual + pages for CVS: cvs(1) and cvs(5). Most of the new CVS 1.3 features + are now documented, with the exception of the new branch support + added to commit/rtag/tag/checkout/update. + + * The -j options of checkout/update have been added. The "cvs join" + command has been removed. + + With one -j option, CVS will merge the changes made between the + resulting revision and the revision that it is based on (e.g., if + the tag refers to a branch, CVS will merge all changes made in + that branch into your working file). + + With two -j options, CVS will merge in the changes between the two + respective revisions. This can be used to "remove" a certain delta + from your working file. E.g., If the file foo.c is based on + revision 1.6 and I want to remove the changes made between 1.3 and + 1.5, I might do: + + % cvs update -j1.5 -j1.3 foo.c # note the order... + + In addition, each -j option can contain on optional date + specification which, when used with branches, can limit the chosen + revision to one within a specific date. An optional date is + specified by adding a colon (:) to the tag, as in: + + -jSymbolic_Tag:Date_Specifier + + An example might be what "cvs import" tells you to do when you have + just imported sources that have conflicts with local changes: + + % cvs checkout -jTAG:yesterday -jTAG module + + which tells CVS to merge in the changes made to the branch + specified by TAG in the last 24 hours. If this is not what is + intended, substitute "yesterday" for whatever format of date that + is appropriate, like: + + % cvs checkout -jTAG:'1 week ago' -jTAG module + + * "cvs diff" now supports the special tags "BASE" and "HEAD". So, + the command: + + % cvs diff -u -rBASE -rHEAD + + will effectively show the changes made by others (in unidiff + format) that will be merged into your working sources with your + next "cvs update" command. "-rBASE" resolves to the revision that + your working file is based on. "-rHEAD" resolves to the current + head of the branch or trunk that you are working on. + + * The -P option of "cvs checkout" now means to Prune empty + directories, as with "update". The default is to not remove empty + directories. However, if you do "checkout" with any -r options, -P + will be implied. I.e., checking out with a tag will cause empty + directories to be pruned automatically. + + * The new file INSTALL describes how to install CVS, including + detailed descriptions of interfaces to "configure". + + * The example loginfo file in examples/loginfo has been updated to + use the perl script included in contrib/log.pl. The nice thing + about this log program is that it records the revision numbers of + your change in the log message. + + Example files for commitinfo and rcsinfo are now included in the + examples directory. + + * All "#if defined(__STDC__) && __STDC__ == 1" lines have been + changed to be "#if __STDC__" to fix some problems with the former. + + * The lib/regex.[ch] files have been updated to the 1.3 release of + the GNU regex package. + + * The ndbm emulation routines included with CVS 1.3 Beta-2 in the + src/ndbm.[ch] files has been moved into the src/myndbm.[ch] files + to avoid any conflict with the system <ndbm.h> header file. If + you had a previous CVS 1.3 Beta release, you will want to "cvs + remove ndbm.[ch]" form your copy of CVS as well. + + * "cvs add" and "cvs remove" are a bit more verbose, telling you + what to do to add/remove your file permanently. + + * We no longer mess with /dev/tty in "commit" and "add". + + * More things are quiet with the -Q option set. + + * New src/config.h option: If CVS_BADROOT is set, CVS will not + allow people really logged in as "root" to commit changes. + + * "cvs diff" exits with a status of 0 if there were no diffs, 1 if + there were diffs, and 2 if there were errors. + + * "cvs -n diff" is now supported so that you can still run diffs + even while in the middle of committing files. + + * Handling of the CVS/Entries file is now much more robust. + + * The default file ignore list now includes "*.so". + + * "cvs import" did not expand '@' in the log message correctly. It + does now. Also, import now uses the ignore file facility + correctly. + + Import will now tell you whether there were conflicts that need to + be resolved, and how to resolve them. + + * "cvs log" has been changed so that you can "log" things that are + not a part of the current release (in the Attic). + + * If you don't change the editor message on commit, CVS now prompts + you with the choice: + + !)reuse this message unchanged for remaining dirs + + which allows you to tell CVS that you have no intention of changing + the log message for the remainder of the commit. + + * It is no longer necessary to have CVSROOT set if you are using + the -H option to get Usage information on the commands. + + * Command argument changes: + checkout: -P handling changed as described above. + New -j option (up to 2 can be specified) + for doing rcsmerge kind of things on + checkout. + commit: -r option now supports committing to a + numeric or symbolic tags, with some + restrictions. Full consistency checks will + be done. + Added "-f logfile" option, which tells + commit to glean the log message from the + specified file, rather than invoking the + editor. + rtag: Added -b option to create a branch tag, + useful for creating a patch for a previous + release, or for forking development. + tag: Added -b option to create a branch tag, + useful for creating a patch for a previous + release, or for forking development. + update: New -j option (up to 2 can be specified) + for doing rcsmerge kind of things on + update. + +Thu Jan 9 10:51:35 MST 1992 Jeff Polk (polk at BSDI.COM) + + * Changes between CVS 1.3 Beta-1 and CVS 1.3 Beta-2 + + * Thanks to K.

Note also that the + "-nfc1" or "-nfca" may be appropriate in files where comments have + been carefully formatted (e.g, modules.c). + +Sat Dec 14 20:35:22 1991 Brian Berliner (berliner at sun.com) + + * Changes between CVS 1.2 and CVS 1.3 Beta are described here. + + * Lots of portability work. CVS now uses the GNU "configure" + script to dynamically determine the features provided by your + system. It probably is not foolproof, but it is better than + nothing. Please let me know of any portability problems. Some + file names were changed to fit within 14-characters. + + * CVS has a new RCS parser that is much more flexible and + extensible. It should read all known RCS ",v" format files. + + * Most of the commands now are fully recursive, rather than just + operating on the current directory alone. This includes "commit", + which makes it real easy to do an "atomic" commit of all the + changes made to a CVS hierarchy of sources. Most of the commands + also correctly handle file names that are in directories other than + ".", including absolute path names. Commands now accept the "-R" + option to force recursion on (though it is always the default now) + and the "-l" option to force recursion off, doing just "." and not + any sub-directories. + + * CVS supports many of the features provided with the RCS 5.x + distribution - including the new "-k" keyword expansion options. I + recommend using RCS 5.x (5.6 is the current official RCS version) + and GNU diff 1.15 (or later) distributions with CVS. + + * Checking out files with symbolic tags/dates is now "sticky", in + that CVS remembers the tag/date used for each file (and directory) + and will use that tag/date automatically on the next "update" call. + This stickyness also holds for files checked out with the the new + RCS 5.x "-k" options. + + * The "cvs diff" command now recognizes all of the rcsdiff 5.x + options. Unidiff format is available by installing the GNU + diff 1.15 distribution. + + * The old "CVS.adm" directories created on checkout are now called + "CVS" directories, to look more like "RCS" and "SCCS". Old CVS.adm + directories are automagically converted to CVS directories. The + old "CVSROOT.adm" directory within the source repository is + automagically changed into a "CVSROOT" directory as well. + + * Symbolic links in the source repository are fully supported ONLY + if you use RCS 5.6 or later and (of course) your system supports + symlinks. + + * A history database has been contributed which maintains the + history of certain CVS operations, as well as providing a wide array + of querying options. + + * The "cvs" program has a "-n" option which can be used with the + "update" command to show what would be updated without actually + doing the update, like: "cvs -n update". All usage statements + have been cleaned up and made more verbose. + + * The module database parsing has been rewritten. The new format + is compatible with the old format, but with much more + functionality. It allows modules to be created that grab pieces or + whole directories from various different parts of your source + repository. Module-relative specifications are also correctly + recognized now, like "cvs checkout module/file.c". + + * A configurable template can be specified such that on a "commit", + certain directories can supply a template that the user must fill + before completing the commit operation. + + * A configurable pre-commit checking program can be specified which + will run to verify that a "commit" can happen. This feature can be + used to restrict certain users from changing certain pieces of the + source repository, or denying commits to the entire source + repository. + + * The new "cvs export" command is much like "checkout", but + establishes defaults suitable for exporting code to others (expands + out keywords, forces the use of a symbolic tag, and does not create + "CVS" directories within the checked out sources. + + * The new "cvs import" command replaces the deprecated "checkin" + shell script and is used to import sources into CVS control. It is + also much faster for the first-time import. Some algorithmic + improvements have also been made to reduce the number of + conflicting files on next-time imports. + + * The new "cvs admin" command is basically an interface to the + "rcs" program. (Not yet implemented very well). + + * Signal handling (on systems with BSD or POSIX signals) is much + improved. Interrupting CVS now works with a single interrupt! + + * CVS now invokes RCS commands by direct fork/exec rather than + calling system(3). This improves performance by removing a call to + the shell to parse the arguments. + + * Support for the .cvsignore file has been contributed. CVS will + now show "unknown" files as "? filename" as the result of an "update" + command. The .cvsignore file can be used to add files to the + current list of ignored files so that they won't show up as unknown. + + * Command argument changes: + cvs: Added -l to turn off history logging. + Added -n to show what would be done without actually + doing anything. + Added -q/-Q for quiet and really quiet settings. + Added -t to show debugging trace. + add: Added -k to allow RCS 5.x -k options to be specified. + admin: New command; an interface to rcs(1). + checkout: Added -A to reset sticky tags/date/options. + Added -N to not shorten module paths. + Added -R option to force recursion. + Changed -p (prune empty directories) to -P option. + Changed -f option; forcing tags match is now default. + Added -p option to checkout module to standard output. + Added -s option to cat the modules db with status. + Added -d option to checkout in the specified directory. + Added -k option to use RCS 5.x -k support. + commit: Removed -a option; use -l instead. + Removed -f option. + Added -l option to disable recursion. + Added -R option to force recursion. + If no files specified, commit is recursive. + diff: Now recognizes all RCS 5.x rcsdiff options. + Added -l option to disable recursion. + Added -R option to force recursion. + history: New command; displays info about CVS usage. + import: Replaces "checkin" shell script; imports sources + under CVS control. Ignores files on the ignore + list (see -I option or .cvsignore description above). + export: New command; like "checkout", but w/special options + turned on by default to facilitate exporting sources. + join: Added -B option to join from base of the branch; + join now defaults to only joining with the top two + revisions on the branch. + Added -k option for RCS 5.x -k support. + log: Supports all RCS 5.x options. + Added -l option to disable recursion. + Added -R option to force recursion. + patch: Changed -f option; forcing tags match is now default. + Added -c option to force context-style diffs. + Added -u option to support unidiff-style diffs. + Added -V option to support RCS specific-version + keyword expansion formats. + Added -R option to force recursion. + remove: No option changes. It's a bit more verbose. + rtag: Equivalent to the old "cvs tag" command. + No option changes. It's a lot faster for re-tag. + status: New output formats with more information. + Added -l option to disable recursion. + Added -R option to force recursion. + Added -v option to show symbolic tags for files. + tag: Functionality changed to tag checked out files + rather than modules; use "rtag" command to get the + old "cvs tag" behaviour. + update: Added -A to reset sticky tags/date/options. + Changed -p (prune empty directories) to -P option. + Changed -f option; forcing tags match is now default. + Added -p option to checkout module to standard output. + Added -I option to add files to the ignore list. + Added -R option to force recursion. + + Major Contributors: + + * Jeff Polk <polk@bsdi.com> rewrote most of the grody code of CVS + 1.2. He made just about everything dynamic (by using malloc), + added a generic hashed list manager, re-wrote the modules database + parsing in a compatible - but extended way, generalized directory + hierarchy recursion for virtually all the commands (including + commit!), generalized the loginfo file to be used for pre-commit + checks and commit templates, wrote a new and flexible RCS parser, + fixed an uncountable number of bugs, and helped in the design of + future CVS features. If there's anything gross left in CVS, it's + probably my fault! + + * David G. Grubbs <dgg@odi.com> contributed the CVS "history" and + "release" commands. As well as the ever-so-useful "-n" option of + CVS which tells CVS to show what it would do, without actually + doing it.

Improved Efficency + +* CVS uses a single doubly linked list/hash table data structure for + all of its lists. Since the back links are only used for deleting + list nodes it might be beneficial to use singly linked lists or a + tree structure. Most likely, a single list implementation will not + be appropriate for all uses. + + One easy change would be to remove the "type" field out of the list + and node structures.

The overhead of malloc()/strcpy()/free() + needs to be measured. If significant, it could be minimized by using a + reference counted string "class". + +* File modification time is stored as a character string. It might be + worthwile to use a time_t internally if the time to convert a time_t + (from struct stat) to a string is greater that the time to convert a + ctime style string (from the entries file) to a time_t. time_t is + an machine-dependant type (although it's pretty standard on UN*X + systems), so we would have to have different conversion routines. + Profiles show that both operations are called about the same number + of times. + +* stat() is one of the largest performance bottlenecks on systems + without the 4.4BSD filesystem. By spliting information out of + the filesystem (perhaps the "rename database") we should be + able to improve performance. + +* Parsing RCS files is very expensive.

In most cases the correct +.I site +will be the default. This argument indicates the support site which +is responsible for the category of problem involved. Some sites may +use a local address as a default. +.I site +values are defined by using the +.BR aliases (5). +.LP +.B cvsbug +invokes an editor on a problem report template (after trying to fill +in some fields with reasonable default values). When you exit the +editor, +.B cvsbug +sends the completed form to the +.I Problem Report Management System +(\fBGNATS\fR) at a central support site. At the support site, the PR +is assigned a unique number and is stored in the \fBGNATS\fR database +according to its category and submitter-id. \fBGNATS\fR automatically +replies with an acknowledgement, citing the category and the PR +number. +.LP +To ensure that a PR is handled promptly, it should contain your (unique) +\fIsubmitter-id\fR and one of the available \fIcategories\fR to identify the +problem area. (Use +.B `cvsbug -L' +to see a list of categories.) +.LP +The +.B cvsbug +template at your site should already be customized with your +submitter-id (running `\|\fBinstall-sid\fP \fIsubmitter-id\fP\|' to +accomplish this is part of the installation procedures for +.BR cvsbug ). +If this hasn't been done, see your system administrator for your +submitter-id, or request one from your support site by invoking +.B `cvsbug \-\-request\-id'. +If your site does not distinguish between different user sites, or if +you are not affiliated with the support site, use +.B `net' +for this field. +.LP +The more precise your problem description and the more complete your +information, the faster your support team can solve your problems. +.SH OPTIONS +.TP +.BI \-f " problem-report" +specify a file (\fIproblem-report\fR) which already contains a +complete problem report. +.B cvsbug +sends the contents of the file without invoking the editor. If +the value for +.I problem-report +is +.BR `\|\-\|' , +then +.B cvsbug +reads from standard input. +.TP +.BI \-t " mail-address" +Change mail address at the support site for problem reports. The +default +.I mail-address +is the address used for the default +.IR site . +Use the +.I site +argument rather than this option in nearly all cases. +.TP +.B \-P +print the form specified by the environment variable +.B PR_FORM +on standard output. If +.B PR_FORM +is not set, print the standard blank PR template. No mail is sent. +.TP +.B -L +print the list of available categories. No mail is sent. +.TP +.B \-\-request\-id +sends mail to the default support site, or +.I site +if specified, with a request for your +.IR submitter-id . +If you are +not affiliated with +.IR site , +use a +.I submitter-id +of +.BR net \|'. +.TP +.B \-v +Display the +.B cvsbug +version number. +.LP +Note: use +.B cvsbug +to submit problem reports rather than mailing them directly. Using +both the template and +.B cvsbug +itself will help ensure all necessary information will reach the +support site. +.SH ENVIRONMENT +The environment variable +.B EDITOR +specifies the editor to invoke on the template. +.br +default: +.B vi +.sp +If the environment variable +.B PR_FORM +is set, then its value is used as the file name of the template for +your problem-report editing session. You can use this to start with a +partially completed form (for example, a form with the identification +fields already completed). +.SH "HOW TO FILL OUT A PROBLEM REPORT" +Problem reports have to be in a particular form so that a program can +easily manage them. Please remember the following guidelines: +.IP \(bu 3m +describe only +.B one problem +with each problem report. +.IP \(bu 3m +For follow-up mail, use the same subject line as the one in the automatic +acknowledgent. It consists of category, PR number and the original synopsis +line. This allows the support site to relate several mail messages to a +particular PR and to record them automatically. +.IP \(bu 3m +Please try to be as accurate as possible in the subject and/or synopsis line. +.IP \(bu 3m +The subject and the synopsis line are not confidential. This is +because open-bugs lists are compiled from them. Avoid confidential +information there. +.LP +See the GNU +.B Info +file +.B cvsbug.info +or the document \fIReporting Problems With cvsbug\fR\ for detailed +information on reporting problems +.SH "HOW TO SUBMIT TEST CASES, CODE, ETC." +Submit small code samples with the PR.

The current server +implementation is a long way from being able to do any of these +things. The protocol, however, is not known to contain any defects +which would preclude them. + +@item +The server never has to have any CVS locks in place while it is waiting +for communication with the client. This makes things robust in the face +of flaky networks. + +@item +Data is transferred in large chunks, which is necessary for good +performance. In fact, currently the client uploads all the data +(without waiting for server responses), and then waits for one server +response (which consists of a massive download of all the data). There +may be cases in which it is better to have a richer interraction, but +the need for the server to release all locks whenever it waits for the +client makes it complicated. +@end itemize + +@node Notes +@chapter Notes on the Current Implementation + +The client is built in to the normal @code{cvs} program, triggered by a +@code{CVSROOT} variable containing a colon, for example +@code{cygnus.com:/rel/cvsfiles}. + +The client stores what is stored in checked-out directories (including +@file{CVS}). The way these are stored is totally compatible with +standard CVS. The server requires no storage other than the repository, +which also is totally compatible with standard CVS. + +The server is started by @code{cvs server}. There is no particularly +compelling reason for this rather than making it a separate program +which shares a lot of sources with cvs. + +The server can also be started by @code{cvs kserver}, in which case it +does an initial Kerberos authentication on stdin. If the authentication +succeeds, it subsequently runs identically to @code{cvs server}. + +The current server implementation can use up huge amounts of memory +when transmitting a lot of data over a slow link (i.e. the network is +slower than the server can generate the data). Avoiding this is +tricky because of the goal of not having the server block on the +network when it has locks open (this could lock the repository for +hours if things are running smoothly or longer if not). Several +solutions are possible. The two-pass design would involve first +noting what versions of everything we need (with locks in place) and +then sending the data, blocking on the network, with no locks needed. +The lather-rinse-repeat design would involve doing things as it does +now until a certain amount of server memory is being used (10M?), then +releasing locks, and trying the whole update again (some of it is +presumably already done). One problem with this is getting merges to +work right. The two-pass design appears to be the more elegant of the +two (it actually reduces the amount of time that locks need to be in +place), but people have expressed concerns about whether it would be +slower (because it traverses the repository twice). It is not clear +whether this is a real problem (looking for whether a file needs to be +updated and actually checking it out are done separately already), but +I don't think anyone has investigated carefully. One hybrid approach +which avoids the problem with merges would be to start out in one-pass +mode and switch to two-pass mode if data is backing up--but this +complicates the code and should be undertaken only if the pure +two-pass design is shown to be flawed. + +@node How To +@chapter How to add more remote commands + +It's the usual simple twelve step process. Let's say you're making +the existing @code{cvs fix} command work remotely. + +@itemize @bullet +@item +Add a declaration for the @code{fix} function, which already implements +the @code{cvs fix} command, to @file{server.c}. +@item +Now, the client side. +Add a function @code{client_fix} to @file{client.c}, which calls +@code{parse_cvsroot} and then calls the usual @code{fix} function. +@item +Add a declaration for @code{client_fix} to @file{client.h}. +@item +Add @code{client_fix} to the "fix" entry in the table of commands in +@file{main.c}. +@item +Now for the server side. +Add the @code{serve_fix} routine to @file{server.c}; make it do: +@example @code +static void +serve_fix (arg) + char *arg; +@{ + do_cvs_command (fix); +@} +@end example +@item +Add the server command @code{"fix"} to the table of requests in @file{server.c}. +@item +The @code{fix} function can now be entered in three different situations: +local (the old situation), client, and server. On the server side it probably +will not need any changes to cope. +Modify the @code{fix} function so that if it is run when the variable +@code{client_active} is set, it starts the server, sends over parsed +arguments and possibly files, sends a "fix" command to the server, +and handles responses from the server. Sample code: +@example @code + if (!client_active) @{ + /* Do whatever you used to do */ + @} else @{ + /* We're the local client. Fire up the remote server. */ + start_server (); + + if (local) + if (fprintf (to_server, "Argument -l\n") == EOF) + error (1, errno, "writing to server"); + send_option_string (options); + + send_files (argc, argv, local); + + if (fprintf (to_server, "fix\n") == EOF) + error (1, errno, "writing to server"); + err = get_responses_and_close (); + @} +@end example +@item +Build it locally. Copy the new version into somewhere on the +remote system, in your path so that @code{rsh host cvs} finds it. +Now you can test it. +@item +You may want to set the environment variable @code{CVS_CLIENT_PORT} to +-1 to prevent the client from contacting the server via a direct TCP +link. That will force the client to fall back to using @code{rsh}, +which will run your new binary. +@item +Set the environment variable @code{CVS_CLIENT_LOG} to a filename prefix +such as @file{/tmp/cvslog}. Whenever you run a remote CVS command, +the commands and responses sent across the client/server connection +will be logged in @file{/tmp/cvslog.in} and @file{/tmp/cvslog.out}. +Examine them for problems while you're testing. +@end itemize + +This should produce a good first cut at a working remote @code{cvs fix} +command. You may have to change exactly how arguments are passed, +whether files or just their names are sent, and how some of the deeper +infrastructure of your command copes with remoteness. + +@node Protocol Notes +@chapter Notes on the Protocol + +A number of enhancements are possible: + +@itemize @bullet +@item +The @code{Modified} request could be speeded up by sending diffs rather +than entire files. The client would need some way to keep the version +of the file which was originally checked out, which would double client +disk space requirements or require coordination with editors (e.g. maybe +it could use emacs numbered backups). This would also allow local +operation of @code{cvs diff} without arguments. + +@item +Have the client keep a copy of some part of the repository. This allows +all of @code{cvs diff} and large parts of @code{cvs update} and +@code{cvs ci} to be local. The local copy could be made consistent with +the master copy at night (but if the master copy has been updated since +the latest nightly re-sync, then it would read what it needs to from the +master). + +@item +Provide encryption using kerberos. + +@item +The current procedure for @code{cvs update} is highly sub-optimal if +there are many modified files. One possible alternative would be to +have the client send a first request without the contents of every +modified file, then have the server tell it what files it needs. Note +the server needs to do the what-needs-to-be-updated check twice (or +more, if changes in the repository mean it has to ask the client for +more files), because it can't keep locks open while waiting for the +network. Perhaps this whole thing is irrelevant if client-side +repositories are implemented, and the rcsmerge is done by the client. +@end itemize + +@node Protocol +@chapter The CVS client/server protocol + +@menu +* Entries Lines:: +* Modes:: +* Requests:: +* Responses:: +* Example:: +@end menu + +@node Entries Lines +@section Entries Lines + +Entries lines are transmitted as: + +@example +/ @var{name} / @var{version} / @var{conflict} / @var{options} / @var{tag_or_date} +@end example + +@var{tag_or_date} is either @samp{T} @var{tag} or @samp{D} @var{date} +or empty.

If at all possible, give these their +POSIX meaning and use other mode-types for other behaviors. For +example, on VMS it shouldn't be hard to make the groups behave like +POSIX, but you would need to use ACLs for some cases. + +@var{data} consists of any data not containing @samp{,}, @samp{\0} or +@samp{\n}. For @samp{u}, @samp{g}, and @samp{o} mode types, data +consists of alphanumeric characters, where @samp{r} means read, @samp{w} +means write, @samp{x} means execute, and unrecognized letters are +silently ignored. + +@node Requests +@section Requests + +File contents (noted below as @var{file transmission}) can be sent in +one of two forms. The simpler form is a number of bytes, followed by a +newline, followed by the specified number of bytes of file contents. +These are the entire contents of the specified file. Second, if both +client and server support @samp{gzip-file-contents}, a @samp{z} may +precede the length, and the `file contents' sent are actually compressed +with @samp{gzip}. The length specified is that of the compressed +version of the file. + +In neither case are the file content followed by any additional data. +The transmission of a file will end with a newline iff that file (or its +compressed form) ends with a newline. + +@table @code +@item Root @var{pathname} \n +Response expected: no. +Tell the server which @code{CVSROOT} to use. + +@item Valid-responses @var{request-list} \n +Response expected: no. +Tell the server what responses the client will accept. +request-list is a space separated list of tokens. + +@item valid-requests \n +Response expected: yes. +Ask the server to send back a @code{Valid-requests} response. + +@item Repository @var{repository} \n +Response expected: no. Tell the server what repository to use. This +should be a directory name from a previous server response. Note that +this both gives a default for @code{Entry } and @code{Modified } and +also for @code{ci} and the other commands; normal usage is to send a +@code{Repository } for each directory in which there will be an +@code{Entry } or @code{Modified }, and then a final @code{Repository } +for the original directory, then the command. + +@item Directory @var{local-directory} \n +Additional data: @var{repository} \n. This is like @code{Repository}, +but the local name of the directory may differ from the repository name. +If the client uses this request, it affects the way the server returns +pathnames; see @ref{Responses}. @var{local-directory} is relative to +the top level at which the command is occurring (i.e. the last +@code{Directory} or @code{Repository} which is sent before the command). + +@item Max-dotdot @var{level} \n +Tell the server that @var{level} levels of directories above the +directory which @code{Directory} requests are relative to will be +needed. For example, if the client is planning to use a +@code{Directory} request for @file{../../foo}, it must send a +@code{Max-dotdot} request with a @var{level} of at least 2. +@code{Max-dotdot} must be sent before the first @code{Directory} +request. + +@item Static-directory \n +Response expected: no. Tell the server that the directory most recently +specified with @code{Repository} or @code{Directory} should not have +additional files checked out unless explicitly requested. The client +sends this if the @code{Entries.Static} flag is set, which is controlled +by the @code{Set-static-directory} and @code{Clear-static-directory} +responses. + +@item Sticky @var{tagspec} \n +Response expected: no. Tell the server that the directory most recently +specified with @code{Repository} has a sticky tag or date @var{tagspec}. +The first character of @var{tagspec} is @samp{T} for a tag, or @samp{D} +for a date. The remainder of @var{tagspec} contains the actual tag or +date. + +@item Checkin-prog @var{program} \n +Response expected: no. Tell the server that the directory most recently +specified with @code{Directory} has a checkin program @var{program}. +Such a program would have been previously set with the +@code{Set-checkin-prog} response. + +@item Update-prog @var{program} \n +Response expected: no. Tell the server that the directory most recently +specified with @code{Directory} has an update program @var{program}. +Such a program would have been previously set with the +@code{Set-update-prog} response. + +@item Entry @var{entry-line} \n +Response expected: no. Tell the server what version of a file is on the +local machine. The name in @var{entry-line} is a name relative to the +directory most recently specified with @code{Repository}. If the user +is operating on only some files in a directory, @code{Entry} requests +for only those files need be included. If an @code{Entry} request is +sent without @code{Modified}, @code{Unchanged}, or @code{Lost} for that +file the meaning depends on whether @code{UseUnchanged} has been sent; +if it has been it means the file is lost, if not it means the file is +unchanged. + +@item Modified @var{filename} \n +Response expected: no. Additional data: mode, \n, file transmission. +Send the server a copy of one locally modified file. @var{filename} is +relative to the most recent repository sent with @code{Repository}. If +the user is operating on only some files in a directory, only those +files need to be included. This can also be sent without @code{Entry}, +if there is no entry for the file. + +@item Lost @var{filename} \n +Response expected: no. Tell the server that @var{filename} no longer +exists. The name is relative to the most recent repository sent with +@code{Repository}. This is used for any case in which @code{Entry} is +being sent but the file no longer exists. If the client has issued the +@code{UseUnchanged} request, then this request is not used. + +@item Unchanged @var{filename} \n +Response expected: no. Tell the server that @var{filename} has not been +modified in the checked out directory. The name is relative to the most +recent repository sent with @code{Repository}. This request can only be +issued if @code{UseUnchanged} has been sent. + +@item UseUnchanged \n +Response expected: no. Tell the server that the client will be +indicating unmodified files with @code{Unchanged}, and that files for +which no information is sent are nonexistent on the client side, not +unchanged. This is necessary for correct behavior since only the server +knows what possible files may exist, and thus what files are +nonexistent. + +@item Argument @var{text} \n +Response expected: no. +Save argument for use in a subsequent command. Arguments +accumulate until an argument-using command is given, at which point +they are forgotten. + +@item Argumentx @var{text} \n +Response expected: no. Append \n followed by text to the current +argument being saved. + +@item Global_option @var{option} \n +Transmit one of the global options @samp{-q}, @samp{-Q}, @samp{-l}, +@samp{-t}, @samp{-r}, or @samp{-n}. @var{option} must be one of those +strings, no variations (such as combining of options) are allowed. For +graceful handling of @code{valid-requests}, it is probably better to +make new global options separate requests, rather than trying to add +them to this request. + +@item expand-modules \n +Response expected: yes. Expand the modules which are specified in the +arguments. Returns the data in @code{Module-expansion} responses. Note +that the server can assume that this is checkout or export, not rtag or +rdiff; the latter do not access the working directory and thus have no +need to expand modules on the client side. + +@item co \n +@itemx update \n +@itemx ci \n +@itemx diff \n +@itemx tag \n +@itemx status \n +@itemx log \n +@itemx add \n +@itemx remove \n +@itemx rdiff \n +@itemx rtag \n +@itemx import \n +@itemx admin \n +@itemx export \n +@itemx history \n +@itemx release \n +Response expected: yes. Actually do a cvs command. This uses any +previous @code{Argument}, @code{Repository}, @code{Entry}, +@code{Modified}, or @code{Lost} requests, if they have been sent. The +last @code{Repository} sent specifies the working directory at the time +of the operation. No provision is made for any input from the user. +This means that @code{ci} must use a @code{-m} argument if it wants to +specify a log message. + +@item update-patches \n +This request does not actually do anything. It is used as a signal that +the server is able to generate patches when given an @code{update} +request. The client must issue the @code{-u} argument to @code{update} +in order to receive patches. + +@item gzip-file-contents @var{level} \n +This request asks the server to filter files it sends to the client +through the @samp{gzip} program, using the specified level of +compression. If this request is not made, the server must not do any +compression. + +This is only a hint to the server. It may still decide (for example, in +the case of very small files, or files that already appear to be +compressed) not to do the compression. Compression is indicated by a +@samp{z} preceding the file length. + +Availability of this request in the server indicates to the client that +it may compress files sent to the server, regardless of whether the +client actually uses this request. + +@item @var{other-request} @var{text} \n +Response expected: yes. +Any unrecognized request expects a response, and does not +contain any additional data. The response will normally be something like +@samp{error unrecognized request}, but it could be a different error if +a previous command which doesn't expect a response produced an error. +@end table + +When the client is done, it drops the connection. + +@node Responses +@section Responses + +After a command which expects a response, the server sends however many +of the following responses are appropriate. Pathnames are of the actual +files operated on (i.e. they do not contain @samp{,v} endings), and are +suitable for use in a subsequent @code{Repository} request. However, if +the client has used the @code{Directory} request, then it is instead a +local directory name relative to the directory in which the command was +given (i.e. the last @code{Directory} before the command). Then a +newline and a repository name (the pathname which is sent if +@code{Directory} is not used). Then the slash and the filename. For +example, for a file @file{i386.mh} which is in the local directory +@file{gas.clean/config} and for which the repository is +@file{/rel/cvsfiles/devo/gas/config}: + +@example +gas.clean/config/ +/rel/cvsfiles/devo/gas/config/i386.mh +@end example + +Any response always ends with @samp{error} or @samp{ok}. This indicates +that the response is over. + +@table @code +@item Valid-requests @var{request-list} \n +Indicate what requests the server will accept. @var{request-list} +is a space separated list of tokens. If the server supports sending +patches, it will include @samp{update-patches} in this list. The +@samp{update-patches} request does not actually do anything. + +@item Checked-in @var{pathname} \n +Additional data: New Entries line, \n. This means a file @var{pathname} +has been successfully operated on (checked in, added, etc.). name in +the Entries line is the same as the last component of @var{pathname}. + +@item New-entry @var{pathname} \n +Additional data: New Entries line, \n. Like @code{Checked-in}, but the +file is not up to date. + +@item Updated @var{pathname} \n +Additional data: New Entries line, \n, mode, \n, file transmission. A +new copy of the file is enclosed. This is used for a new revision of an +existing file, or for a new file, or for any other case in which the +local (client-side) copy of the file needs to be updated, and after +being updated it will be up to date. If any directory in pathname does +not exist, create it. + +@item Merged @var{pathname} \n +This is just like @code{Updated} and takes the same additional data, +with the one difference that after the new copy of the file is enclosed, +it will still not be up to date. Used for the results of a merge, with +or without conflicts. + +@item Patched @var{pathname} \n +This is just like @code{Updated} and takes the same additional data, +with the one difference that instead of sending a new copy of the file, +the server sends a patch produced by @samp{diff -u}. This client must +apply this patch, using the @samp{patch} program, to the existing file. +This will only be used when the client has an exact copy of an earlier +revision of a file. This response is only used if the @code{update} +command is given the @samp{-u} argument. + +@item Checksum @var{checksum}\n +The @var{checksum} applies to the next file sent over via +@code{Updated}, @code{Merged}, or @code{Patched}. In the case of +@code{Patched}, the checksum applies to the file after being patched, +not to the patch itself. The client should compute the checksum itself, +after receiving the file or patch, and signal an error if the checksums +do not match. The checksum is the 128 bit MD5 checksum represented as +32 hex digits. This response is optional, and is only used if the +client supports it (as judged by the @code{Valid-responses} request). + +@item Copy-file @var{pathname} \n +Additional data: @var{newname} \n. Copy file @var{pathname} to +@var{newname} in the same directory where it already is. This does not +affect @code{CVS/Entries}. + +@item Removed @var{pathname} \n +The file has been removed from the repository (this is the case where +cvs prints @samp{file foobar.c is no longer pertinent}). + +@item Remove-entry @var{pathname} \n +The file needs its entry removed from @code{CVS/Entries}, but the file +itself is already gone (this happens in response to a @code{ci} request +which involves committing the removal of a file). + +@item Set-static-directory @var{pathname} \n +This instructs the client to set the @code{Entries.Static} flag, which +it should then send back to the server in a @code{Static-directory} +request whenever the directory is operated on. @var{pathname} ends in a +slash; its purpose is to specify a directory, not a file within a +directory. + +@item Clear-static-directory @var{pathname} \n +Like @code{Set-static-directory}, but clear, not set, the flag. + +@item Set-sticky @var{pathname} \n +Additional data: @var{tagspec} \n. Tell the client to set a sticky tag +or date, which should be supplied with the @code{Sticky} request for +future operations. @var{pathname} ends in a slash; its purpose is to +specify a directory, not a file within a directory. The first character +of @var{tagspec} is @samp{T} for a tag, or @samp{D} for a date. The +remainder of @var{tagspec} contains the actual tag or date. + +@item Clear-sticky @var{pathname} \n +Clear any sticky tag or date set by @code{Set-sticky}. + +@item Set-checkin-prog @var{dir} \n +Additional data: @var{prog} \n. Tell the client to set a checkin +program, which should be supplied with the @code{Checkin-prog} request +for future operations. + +@item Set-update-prog @var{dir} \n +Additional data: @var{prog} \n. Tell the client to set an update +program, which should be supplied with the @code{Update-prog} request +for future operations. + +@item Module-expansion @var{pathname} \n +Return a file or directory which is included in a particular module. +@var{pathname} is relative to cvsroot, unlike most pathnames in +responses. + +@item M @var{text} \n +A one-line message for the user. + +@item E @var{text} \n +Same as @code{M} but send to stderr not stdout. + +@item error @var{errno-code} @samp{ } @var{text} \n +The command completed with an error. @var{errno-code} is a symbolic +error code (e.g. @code{ENOENT}); if the server doesn't support this +feature, or if it's not appropriate for this particular message, it just +omits the errno-code (in that case there are two spaces after +@samp{error}). Text is an error message such as that provided by +strerror(), or any other message the server wants to use. + +@item ok \n +The command completed successfully. +@end table + +@node Example +@section Example + +Lines beginning with @samp{c>} are sent by the client; lines beginning +with @samp{s>} are sent by the server; lines beginning with @samp{#} are +not part of the actual exchange. + +@example +c> Root /rel/cvsfiles +# In actual practice the lists of valid responses and requests would +# be longer +c> Valid-responses Updated Checked-in M ok error +c> valid-requests +s> Valid-requests Root co Modified Entry Repository ci Argument Argumentx +s> ok +# cvs co devo/foo +c> Argument devo/foo +c> co +s> Updated /rel/cvsfiles/devo/foo/foo.c +s> /foo.c/1.4/Mon Apr 19 15:36:47 1993 Mon Apr 19 15:36:47 1993// +s> 26 +s> int mein () @{ abort (); @} +s> Updated /rel/cvsfiles/devo/foo/Makefile +s> /Makefile/1.2/Mon Apr 19 15:36:47 1993 Mon Apr 19 15:36:47 1993// +s> 28 +s> foo: foo.c +s> $(CC) -o foo $< +s> ok +# In actual practice the next part would be a separate connection. +# Here it is shown as part of the same one. +c> Repository /rel/cvsfiles/devo/foo +# foo.c relative to devo/foo just set as Repository. +c> Entry /foo.c/1.4/Mon Apr 19 15:36:47 1993 Mon Apr 19 15:36:47 1993// +c> Entry /Makefile/1.2/Mon Apr 19 15:36:47 1993 Mon Apr 19 15:36:47 1993// +c> Modified foo.c +c> 26 +c> int main () @{ abort (); @} +# cvs ci -m <log message> foo.c +c> Argument -m +c> Argument Well, you see, it took me hours and hours to find this typo and I +c> Argumentx searched and searched and eventually had to ask John for help. +c> Argument foo.c +c> ci +s> Checked-in /rel/cvsfiles/devo/foo/foo.c +s> /foo.c/1.5/ Mon Apr 19 15:54:22 CDT 1993// +s> M Checking in foo.c; +s> M /cygint/rel/cvsfiles/devo/foo/foo.c,v <-- foo.c +s> M new revision: 1.5; previous revision: 1.4 +s> M done +s> ok +@end example +@bye diff --git a/gnu/usr.bin/cvs/examples/checkoutlist b/gnu/usr.bin/cvs/examples/checkoutlist new file mode 100644 index 0000000..45ee6dc --- /dev/null +++ b/gnu/usr.bin/cvs/examples/checkoutlist @@ -0,0 +1,20 @@ +# +#ident "@(#)cvs/examples:$Name: $:$Id: checkoutlist,v 1.2 1995/11/14 23:24:49 woods Exp $" +# +# The "checkoutlist" file is used to support additional version controlled +# administrative files in $CVSROOT/CVSROOT, such as template files. +# +# The first entry on a line is a filename which will be checked out from +# the corresponding RCS file in the $CVSROOT/CVSROOT directory. +# The remainder of the line is an error message to use if the file cannot +# be checked out. +# +# File format: +# +# [<whitespace>]<filename><whitespace><error message><end-of-line> +# +# comment lines begin with '#' +# +rcstemplate +wrap +unwrap diff --git a/gnu/usr.bin/cvs/examples/cvswrappers b/gnu/usr.bin/cvs/examples/cvswrappers new file mode 100644 index 0000000..c666292 --- /dev/null +++ b/gnu/usr.bin/cvs/examples/cvswrappers @@ -0,0 +1,29 @@ +# +#ident "@(#)cvs/examples:$Name: $:$Id: cvswrappers,v 1.3 1995/11/14 23:23:11 woods Exp $" +# +# This file describes wrappers and other binary files to CVS. +# +# Wrappers are the concept where directories of files are to be +# treated as a single file.
