- Changes since 1.11.1:
-
- * Read only access was broken - now fixed.
-
- Changes since 1.11:
-
- * There was a bug in the diff code which caused conflicts to be flagged which shouldn't
- have been. This has been fixed.
-
- * New "cvs rlog" and "cvs rannotate" commands have been added to get log
- messages and annotations without having to have a checked-out copy.
-
- * The VMS client now accepts wildcards if you're running VMS 7.x.
-
- * ZLIB has been updated to version 1.1.3, the most current version. This
- includes mostly some optimizations and minor bug fixes.
-
- * The ~/.cvspass file has a slightly modified format. CVSROOTs are now
- stored in a new canonical form - hostnames are now case insensitive and port
- numbers are always stored in the new format. Until a new login for a
- particular CVSROOT is performed with the new version of CVS, new and old
- versions of CVS should interoperate invisibly. After that point, an extra login
- using the old version of CVS may be necessary to continue to allow the new and
- old versions of CVS to interoperate using the same ~/.cvspass file and CVSROOT.
- The exception to this rule occurs when the CVSROOTs used with the different
- versions use case insensitively different hostnames, for example, "empress",
- and "empress.2-wit.com".
-
- * A password and a port number may now be specified in CVSROOT for pserver
- connections. The new format is:
-
- :pserver:[[user][:password]@]host[:[port]]/path
-
- Note that passwords specified in a checkout command will be saved in the clear
- in the CVS/Root file in each created directory, so this is not recommended,
- except perhaps when accessing anonymous repositories or the like.
-
- * The distribution has been converted to use Automake. This shouldn't affect
- most users except to ease some portability concerns, but if you are building
- from the repository and encounter problems with the makefiles, you might try
- running ./noautoconf.sh after a fresh update -AC.
-
- Changes since 1.10:
-
- * The new "cvs version" command gives a short version message. If
- the repository is remote, both the client and server versions are
- reported.
-
- * "cvs admin -t" now works correctly in client/server mode.
-
- * The "cvs history" command output format has changed -- the date
- now includes the year and is given is ISO 8601 format (yyyy-mm-dd).
- Also, the new LogHistory option in CVSROOT/config can be used to
- control what information gets recorded in the log file and code has
- been added to record file removals.
-
- * The buggy PreservePermissions code has been disabled.
-
- * Anonymous read-only access can now be done without requiring a
- password. On the server side, simply give that user (presumably
- `anonymous') an empty password in the CVSROOT/passwd file, and then
- any received password will authenticate successfully.
-
- * There is a new access method :fork: which is similar to :local:
- except that it is implemented via the CVS remote protocol, and thus
- has a somewhat different set of quirks and bugs.
-
- * The -d command line option no longer updates the CVS/Root file. For
- one thing, the CVS 1.9/1.10 behavior never had updated CVS/Root in
- subdirectories, and for another, it didn't seem that popular in
- general. So this change restores the CVS 1.8 behavior (which is also
- the CVS 1.9/1.10 behavior if the environment variable
- CVS_IGNORE_REMOTE_ROOT is set; with this change,
- CVS_IGNORE_REMOTE_ROOT no longer has any effect).
-
- * It is now possible for a single CVS command to recurse into several
- CVS roots. This includes roots which are located on several servers,
- or which are both remote and local. CVS will make connections to as
- many servers as necessary.
-
- * It is now possible to put the CVS lock files in a directory
- set by the new LockDir option in CVSROOT/config. The default
- continues to be to put the lock files in the repository itself.
-
- Changes from 1.9 to 1.10:
-
- * There is a new feature, enabled by TopLevelAdmin in CVSROOT/config,
- which tells CVS to modify the behavior of the "checkout" command. The
- command now creates a CVS directory at the top level of the new
- working directory, in addition to CVS directories created within
- checked-out directories. See the Cederqvist for details.
-
- * There is an optional set of features, enabled by PreservePermissions
- in CVSROOT/config, which allow CVS to store unix-specific file
- information such as permissions, file ownership, and links. See the
- Cederqvist for details.
-
- * One can now authenticate and encrypt using the GSSAPI network
- security interface. For details see the Cederqvist's description of
- specifying :gserver: in CVSROOT, and the -a global option.
-
- * All access to RCS files is now implemented internally rather than by
- calling RCS programs. The main user-visible consequence of this is
- that there is no need to worry about making sure that CVS finds the
- correct version of RCS. The -b global option and the RCSBIN setting
- in CVSROOT/config are still accepted but don't do anything. The
- $RCSBIN internal variable in administrative files is no longer
- accepted.
-
- * There is a new syntax, "cvs admin -orev1::rev2", which collapses the
- revisions between rev1 and rev2 without deleting rev1 or rev2
- themselves.
-
- * There is a new administrative file CVSROOT/config which allows one
- to specify miscellaneous aspects of CVS configuration. Currently
- supported here:
-
- - SystemAuth, allows you to prevent pserver from checking for system
- usernames/passwords.
-
- For more information see the "config" section of cvs.texinfo.
-
- * When setting up the pserver server, one now must specify the
- allowable CVSROOT directories in inetd.conf. See the Password
- authentication server section of cvs.texinfo for details. Note that
- this implies that everyone who is running a pserver server must edit
- inetd.conf when upgrading their CVS.
-
- * The client no longer needs an external patch program (assuming both
- the client and the server have been updated to the new version).
-
- * "cvs admin [options]" will now recurse. In previous versions of
- CVS, it was an error and one needed to specify "cvs admin [options] ."
- to recurse. This change brings admin in line with the other CVS
- commands.
-
- * New "logout" command to remove the password for a remote cvs
- repository from the cvspass file.
-
- * Read-only repository access is implemented for the
- password-authenticated server (other access methods are just governed
- by Unix file permissions, since they require login access to the
- repository machine anyway). See the "Repository" section of
- cvs.texinfo for details, including a discussion of security issues.
- Note that the requirement that read-only users be able to create locks
- and write the history file still applies.
-
- * There is a new administrative file verifymsg which is like editinfo
- but merely validates the message, rather than also getting it from the
- user. It therefore works with client/server CVS or if one uses the -m
- or -F options to commit. See the verifymsg section of cvs.texinfo for
- details.
-
- * The %s format formerly accepted in loginfo has been extended to
- formats such as %{sVv}, so that loginfo scripts have access to the
- version numbers being changed. See the Loginfo section of cvs.texinfo
- for details.
-
- * The postscript documentation (doc/cvs.ps) shipped with CVS is now
- formatted for US letter size instead of A4. This is not because we
- consider this size "better" than A4, but because we believe that the
- US letter version will print better on A4 paper than the other way
- around.
-
- * The "cvs export" command is now logged in the history file and there
- is a "cvs history -x E" command to select history file entries
- produced by export.
-
- * CVS no longer uses the CVS_PASSWORD environment variable. Storing
- passwords in cleartext in an environment variable is a security risk,
- especially since (on BSD variants) any user on the system can display
- any process's environment using 'ps'. Users should use the 'cvs
- login' command instead.
-
-
- Changes from 1.8 to 1.9:
-
- * Windows NT client should now work on Windows 95 as well.
-
- * New option "--help-synonyms" prints a list of all recognized command
- synonyms.
-
- * The "log" command is now implemented internally rather than via the
- RCS "rlog" program. The main user-visible consequence is that
- symbolic branch names now work (for example "cvs log -rbranch1").
- Also, the date formats accepted by -d have changed. They previously
- had been a bewildering variety of poorly-documented date formats. Now
- they are the same as the date formats accepted by the -D options to
- the other CVS commands, which is also a (different) bewildering
- variety of poorly-documented date formats, but at least we are
- consistently bewildering :-).
-
- * Encryption is now supported over a Kerberos client/server
- connection. The new "-x" global option requests it. You must
- configure with the --enable-encryption option in order to enable
- encryption.
-
- * The format of the CVS commit message has changed slightly when
- committing changes on a branch. The tag on which the commit is
- ocurring is now reported correctly in all cases.
-
- * New flag -k in wrappers allows you to specify the keyword expansion
- mode for added files based on their name. For example, you can
- specify that files whose name matches *.exe are binary by default.
- See the Wrappers section of cvs.texinfo for more details.
-
- * Remote CVS with the "-z" option now uses the zlib library (included
- with CVS) to compress all communication between the client and the
- server, rather than invoking gzip on each file separately. This means
- that compression is better and there is no need for an external gzip
- program (except to interoperate with older version of CVS).
-
- * The "cvs rlog" command is deprecated and running it will print a
- warning; use the synonymous "cvs log" command instead. It is
- confusing for rlog to mean the same as log because some other CVS
- commands are in pairs consisting of a plain command which operates on
- a working directory and an "r" command which does not (diff/rdiff;
- tag/rtag).
-
- * "cvs diff" has a bunch of new options, mostly long options. Most of
- these work only if rcsdiff and diff support them, and are named the
- same as the corresponding options to diff.
-
- * The -q and -Q command options to "cvs diff" were removed (use the
- global options instead). This brings "cvs diff" into line with the
- rest of the CVS commands.
-
- * The "annotate" command can now be used to annotate a revision other
- than the head revision on the trunk (see the -r, -D, and -f options in
- the annotate node of cvs.texinfo for details).
-
- * The "tag" command has a new option "-c" which checks that all files
- are not locally modified before tagging.
-
- * The -d command line option now overrides the cvsroot setting stored
- in the CVS/Root file in each working directory, and specifying -d will
- cause CVS/Root to be updated.
-
- * Local (non-client/server) CVS now runs on Windows NT. See
- windows-NT/README for details.
-
- * The CVSROOT variable specification has changed to support more
- access methods. In addition to "pserver," "server" (internal rsh
- client), "ext" (external rsh client), "kserver" (kerberos), and
- "local" (local filesystem access) can now be specified. For more
- details on each method, see cvs.texinfo (there is an index entry for
- :local: and each of the other access methods).
-
- * The "login" command no longer prompts the user for username and
- hostname, since one will have to provide that information via the `-d'
- flag or by setting CVSROOT.
-
- Changes from 1.7 to 1.8:
-
- * New "cvs annotate" command to display the last modification for each
- line of a file, with the revision number, user checking in the
- modification, and date of the modification. For more information see
- the `annotate' node in cvs.texinfo.
-
- * The cvsinit shell script has been replaced by a cvs init command.
- The cvs init command creates some example administrative files which
- are similar to the files found in the examples directory (and copied
- by cvsinit) in previous releases.
-
- * Added the patterns *.olb *.exe _$* *$ to default ignore list.
-
- * There is now a $USER internal variable for *info files.
-
- * There is no longer a separate `mkmodules' program; the functionality
- is now built into `cvs'. If upgrading an old repository, it is OK to
- leave in the lines in the modules file which run mkmodules (the
- mkmodules actions will get done twice, but that is harmless); you will
- probably want to remove them once you are no longer using the old CVS.
-
- * One can now specify user variables in *info files via the
- ${=varname} syntax; there is a -s global option to set them. See the
- Variables node in cvs.texinfo for details.
-
- Changes from 1.6 to 1.7:
-
- * The default ignore list has changed slightly: *.obj has been added
- and CVS* has been changed to CVS CVS.adm.
-
- * CVS now supports password authentication when accessing remote
- repositories; this is useful for sites that can't use rsh (because of
- a firewall, for example), and also don't have kerberos. See node
- "Password authenticated" (in "Remote repositories", in
- doc/cvs.texinfo) for more details. Note: This feature requires both
- the client and server to be upgraded.
-
- * Using the -kb option to specify binary files now works--most cases
- did not work before. See the "Binary files" section of
- doc/cvs.texinfo for details.
-
- * New developer communication features. See the "Watches" section of
- doc/cvs.texinfo for details.
-
- * RCS keyword "Name" supported for "cvs update -r <tag>" and "cvs
- checkout -r <tag>".
-
- * If there is a group whose name matches a compiled in value which
- defaults to "cvsadmin", only members of that group can use "cvs
- admin". This replaces the CVS_NOADMIN option.
-
- * CVS now sets the modes of files in the repository based on the
- CVSUMASK environment variable or a compiled in value defaulting to
- 002. 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 names in .cvsrc now match 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'"). You also can specify global CVS options (like
- "-z") using the command name "cvs".
-
- 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.

-
- * 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.

-
- * 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.

-
- * Changes between CVS 1.3 Beta-1 and CVS 1.3 Beta-2
-
- * Thanks to K. Richard Pixley at Cygnus we now have function
- prototypes in all the files
-
- * Some small changes to configure for portability. There have
- been other portability problems submitted that have not been fixed
- (Brian will be working on those). Additionally all __STDC__
- tests have been modified to check __STDC__ against the constant 1
- (this is what the Second edition of K&R says must be true).
-
- * Lots of additional error checking for forked processes (run_exec)
- (thanks again to K. Richard Pixley)
-
- * Lots of miscellaneous bug fixes - including but certainly not
- limited to:
- various commit core dumps
- various update core dumps
- bogus results from status with numeric sticky tags
- commitprog used freed memory
- Entries file corruption caused by No_Difference
- commit to revision broken (now works if branch exists)
- ignore file processing broken for * and !
- ignore processing didn't handle memory reasonably
- miscellaneous bugs in the recursion processor
- file descriptor leak in ParseInfo
- CVSROOT.adm->CVSROOT rename bug
- lots of lint fixes
-
- * Reformatted all the code in src (with GNU indent) and then
- went back and fixed prototypes, etc since indent gets confused. The
- rationale is that it is better to do it sooner than later and now
- everything is consistent and will hopefully stay that way.
- The basic options to indent were: "-bad -bbb -bap -cdb -d0 -bl -bli0
- -nce -pcs -cs -cli4 -di1 -nbc -psl -lp -i4 -ip4 -c41" and then
- miscellaneous formatting fixes were applied. Note also that the
- "-nfc1" or "-nfca" may be appropriate in files where comments have
- been carefully formatted (e.g, modules.c).

-
- * 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. He also contributed support for the .cvsignore file.
-
- * Paul Sander, HaL Computer Systems, Inc. <paul@hal.com> wrote and
- contributed the code in lib/sighandle.c. I added support for
- POSIX, BSD, and non-POSIX/non-BSD systems.
-
- * Free Software Foundation contributed the "configure" script and
- other compatibility support in the "lib" directory, which will help
- make CVS much more portable.
-
- * Many others have contributed bug reports and enhancement requests.
- Some have even submitted actual code which I have not had time yet
- to integrate into CVS. Maybe for the next release.
-
- * Thanks to you all!
