* 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
* 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
* 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out-of-date and will cause the real commit to fail, or which files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 "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
* 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
* 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

* 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
% cvs rtag -b -rFOO_2_0 FOO_2_0_Patch foo
% cvs checkout -rFOO_2_0_Patch foo
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
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
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
% 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
% cvs checkout -jTAG:'1 week ago' -jTAG module
* "cvs diff" now supports the special tags "BASE" and "HEAD". So,
% 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
* 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 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
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
!)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
commit: -r option now supports committing to a
numeric or symbolic tags, with some
restrictions. Full consistency checks will
Added "-f logfile" option, which tells
commit to glean the log message from the
specified file, rather than invoking the
rtag: Added -b option to create a branch tag,
useful for creating a patch for a previous
release, or for forking development.

* 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
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
* 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
* 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
* The "cvs diff" command now recognizes all of the rcsdiff 5.x
options. Unidiff format is available by installing the GNU
* 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
* A history database has been contributed which maintains the
history of certain CVS operations, as well as providing a wide array
* 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
* 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
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.
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
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
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.
* 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
* David G. Grubbs <dgg@ksr.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.
Wed Feb 6 10:10:58 1991 Brian Berliner (berliner at sun.com)
* Changes from CVS 1.0 Patchlevel 1 to CVS 1.0 Patchlevel 2; also
known as "Changes from CVS 1.1 to CVS 1.2".
* Major new support with this release is the ability to use the
recently-posted RCS 5.5 distribution with CVS 1.2. See below for
other assorted bug-fixes that have been thrown in.
* ChangeLog (new): Added Emacs-style change-log file to CVS 1.2
release. Chronological description of changes between release.
* README: Small fixes to installation instructions. My email
address is now "berliner@sun.com".

Thanks to Paul Eggert <eggert@twinsun.com> for this change.
* src/collect_sets.c (Collect_Sets): Be quieter if "-f" option is
specified. When checking out files on-top-of other files that CVS
doesn't know about, run a diff in the hopes that they are really
the same file before aborting.
* src/commit.c (branch_number): Fix for RCS 5.5 parsing.
Thanks to Paul Eggert <eggert@twinsun.com> for this change.
* src/commit.c (do_editor): Bug fix - fprintf missing argument
which sometimes caused core dumps.

* src/patchlevel.h: Increased patch level to "2".
* src/subr.c (isdir, islink): Changed to compare stat mode bits
* src/tag.c (tag_file): Added support for following symbolic links
that are in the master source repository when tagging. Made tag
somewhat quieter in certain cases.
* src/update.c (update_process_lists): Unlink the user's file if it
was put on the Wlist, meaning that the user's file is not modified
and its RCS file has been removed by someone else.
* src/update.c (update): Support for "cvs update dir" to correctly
just update the argument directory "dir".
* src/cvs.h: Fixes for RCS 5.5 parsing.
* src/version_number.c (Version_Number): Fixes for parsing RCS 5.5
and older RCS-format files.
Thanks to Paul Eggert <eggert@twinsun.com> for these changes.

timelocal() with call to maketime().
Mon Nov 19 23:15:11 1990 Brian Berliner (berliner at prisma.com)
* Sent CVS 1.0 release to comp.sources.unix moderator and FSF.
* Special thanks to Dick Grune <dick@cs.vu.nl> for his work on the
1986 version of CVS and making it available to the world. Dick's
version is available on uunet.uu.net in the
comp.sources.unix/volume6/cvs directory.
