3 * Read only access was broken - now fixed.
7 * There was a bug in the diff code which caused conflicts to be flagged which shouldn't
8 have been. This has been fixed.
10 * New "cvs rlog" and "cvs rannotate" commands have been added to get log
11 messages and annotations without having to have a checked-out copy.
13 * The VMS client now accepts wildcards if you're running VMS 7.x.
15 * ZLIB has been updated to version 1.1.3, the most current version. This
16 includes mostly some optimizations and minor bug fixes.
18 * The ~/.cvspass file has a slightly modified format. CVSROOTs are now
19 stored in a new canonical form - hostnames are now case insensitive and port
20 numbers are always stored in the new format. Until a new login for a
21 particular CVSROOT is performed with the new version of CVS, new and old
22 versions of CVS should interoperate invisibly. After that point, an extra login
23 using the old version of CVS may be necessary to continue to allow the new and
24 old versions of CVS to interoperate using the same ~/.cvspass file and CVSROOT.
25 The exception to this rule occurs when the CVSROOTs used with the different
26 versions use case insensitively different hostnames, for example, "empress",
27 and "empress.2-wit.com".
29 * A password and a port number may now be specified in CVSROOT for pserver
30 connections. The new format is:
32 :pserver:[[user][:password]@]host[:[port]]/path
34 Note that passwords specified in a checkout command will be saved in the clear
35 in the CVS/Root file in each created directory, so this is not recommended,
36 except perhaps when accessing anonymous repositories or the like.
38 * The distribution has been converted to use Automake. This shouldn't affect
39 most users except to ease some portability concerns, but if you are building
40 from the repository and encounter problems with the makefiles, you might try
41 running ./noautoconf.sh after a fresh update -AC.
45 * The new "cvs version" command gives a short version message. If
46 the repository is remote, both the client and server versions are
49 * "cvs admin -t" now works correctly in client/server mode.
51 * The "cvs history" command output format has changed -- the date
52 now includes the year and is given is ISO 8601 format (yyyy-mm-dd).
53 Also, the new LogHistory option in CVSROOT/config can be used to
54 control what information gets recorded in the log file and code has
55 been added to record file removals.
57 * The buggy PreservePermissions code has been disabled.
59 * Anonymous read-only access can now be done without requiring a
60 password. On the server side, simply give that user (presumably
61 `anonymous') an empty password in the CVSROOT/passwd file, and then
62 any received password will authenticate successfully.
64 * There is a new access method :fork: which is similar to :local:
65 except that it is implemented via the CVS remote protocol, and thus
66 has a somewhat different set of quirks and bugs.
68 * The -d command line option no longer updates the CVS/Root file. For
69 one thing, the CVS 1.9/1.10 behavior never had updated CVS/Root in
70 subdirectories, and for another, it didn't seem that popular in
71 general. So this change restores the CVS 1.8 behavior (which is also
72 the CVS 1.9/1.10 behavior if the environment variable
73 CVS_IGNORE_REMOTE_ROOT is set; with this change,
74 CVS_IGNORE_REMOTE_ROOT no longer has any effect).
76 * It is now possible for a single CVS command to recurse into several
77 CVS roots. This includes roots which are located on several servers,
78 or which are both remote and local. CVS will make connections to as
79 many servers as necessary.
81 * It is now possible to put the CVS lock files in a directory
82 set by the new LockDir option in CVSROOT/config. The default
83 continues to be to put the lock files in the repository itself.
85 Changes from 1.9 to 1.10:
87 * There is a new feature, enabled by TopLevelAdmin in CVSROOT/config,
88 which tells CVS to modify the behavior of the "checkout" command. The
89 command now creates a CVS directory at the top level of the new
90 working directory, in addition to CVS directories created within
91 checked-out directories. See the Cederqvist for details.
93 * There is an optional set of features, enabled by PreservePermissions
94 in CVSROOT/config, which allow CVS to store unix-specific file
95 information such as permissions, file ownership, and links. See the
96 Cederqvist for details.
98 * One can now authenticate and encrypt using the GSSAPI network
99 security interface. For details see the Cederqvist's description of
100 specifying :gserver: in CVSROOT, and the -a global option.
102 * All access to RCS files is now implemented internally rather than by
103 calling RCS programs. The main user-visible consequence of this is
104 that there is no need to worry about making sure that CVS finds the
105 correct version of RCS. The -b global option and the RCSBIN setting
106 in CVSROOT/config are still accepted but don't do anything. The
107 $RCSBIN internal variable in administrative files is no longer
110 * There is a new syntax, "cvs admin -orev1::rev2", which collapses the
111 revisions between rev1 and rev2 without deleting rev1 or rev2
114 * There is a new administrative file CVSROOT/config which allows one
115 to specify miscellaneous aspects of CVS configuration. Currently
118 - SystemAuth, allows you to prevent pserver from checking for system
121 For more information see the "config" section of cvs.texinfo.
123 * When setting up the pserver server, one now must specify the
124 allowable CVSROOT directories in inetd.conf. See the Password
125 authentication server section of cvs.texinfo for details. Note that
126 this implies that everyone who is running a pserver server must edit
127 inetd.conf when upgrading their CVS.
129 * The client no longer needs an external patch program (assuming both
130 the client and the server have been updated to the new version).
132 * "cvs admin [options]" will now recurse. In previous versions of
133 CVS, it was an error and one needed to specify "cvs admin [options] ."
134 to recurse. This change brings admin in line with the other CVS
137 * New "logout" command to remove the password for a remote cvs
138 repository from the cvspass file.
140 * Read-only repository access is implemented for the
141 password-authenticated server (other access methods are just governed
142 by Unix file permissions, since they require login access to the
143 repository machine anyway). See the "Repository" section of
144 cvs.texinfo for details, including a discussion of security issues.
145 Note that the requirement that read-only users be able to create locks
146 and write the history file still applies.
148 * There is a new administrative file verifymsg which is like editinfo
149 but merely validates the message, rather than also getting it from the
150 user. It therefore works with client/server CVS or if one uses the -m
151 or -F options to commit. See the verifymsg section of cvs.texinfo for
154 * The %s format formerly accepted in loginfo has been extended to
155 formats such as %{sVv}, so that loginfo scripts have access to the
156 version numbers being changed. See the Loginfo section of cvs.texinfo
159 * The postscript documentation (doc/cvs.ps) shipped with CVS is now
160 formatted for US letter size instead of A4. This is not because we
161 consider this size "better" than A4, but because we believe that the
162 US letter version will print better on A4 paper than the other way
165 * The "cvs export" command is now logged in the history file and there
166 is a "cvs history -x E" command to select history file entries
169 * CVS no longer uses the CVS_PASSWORD environment variable. Storing
170 passwords in cleartext in an environment variable is a security risk,
171 especially since (on BSD variants) any user on the system can display
172 any process's environment using 'ps'. Users should use the 'cvs
173 login' command instead.
176 Changes from 1.8 to 1.9:
178 * Windows NT client should now work on Windows 95 as well.
180 * New option "--help-synonyms" prints a list of all recognized command
183 * The "log" command is now implemented internally rather than via the
184 RCS "rlog" program. The main user-visible consequence is that
185 symbolic branch names now work (for example "cvs log -rbranch1").
186 Also, the date formats accepted by -d have changed. They previously
187 had been a bewildering variety of poorly-documented date formats. Now
188 they are the same as the date formats accepted by the -D options to
189 the other CVS commands, which is also a (different) bewildering
190 variety of poorly-documented date formats, but at least we are
191 consistently bewildering :-).
193 * Encryption is now supported over a Kerberos client/server
194 connection. The new "-x" global option requests it. You must
195 configure with the --enable-encryption option in order to enable
198 * The format of the CVS commit message has changed slightly when
199 committing changes on a branch. The tag on which the commit is
200 ocurring is now reported correctly in all cases.
202 * New flag -k in wrappers allows you to specify the keyword expansion
203 mode for added files based on their name. For example, you can
204 specify that files whose name matches *.exe are binary by default.
205 See the Wrappers section of cvs.texinfo for more details.
207 * Remote CVS with the "-z" option now uses the zlib library (included
208 with CVS) to compress all communication between the client and the
209 server, rather than invoking gzip on each file separately. This means
210 that compression is better and there is no need for an external gzip
211 program (except to interoperate with older version of CVS).
213 * The "cvs rlog" command is deprecated and running it will print a
214 warning; use the synonymous "cvs log" command instead. It is
215 confusing for rlog to mean the same as log because some other CVS
216 commands are in pairs consisting of a plain command which operates on
217 a working directory and an "r" command which does not (diff/rdiff;
220 * "cvs diff" has a bunch of new options, mostly long options. Most of
221 these work only if rcsdiff and diff support them, and are named the
222 same as the corresponding options to diff.
224 * The -q and -Q command options to "cvs diff" were removed (use the
225 global options instead). This brings "cvs diff" into line with the
226 rest of the CVS commands.
228 * The "annotate" command can now be used to annotate a revision other
229 than the head revision on the trunk (see the -r, -D, and -f options in
230 the annotate node of cvs.texinfo for details).
232 * The "tag" command has a new option "-c" which checks that all files
233 are not locally modified before tagging.
235 * The -d command line option now overrides the cvsroot setting stored
236 in the CVS/Root file in each working directory, and specifying -d will
237 cause CVS/Root to be updated.
239 * Local (non-client/server) CVS now runs on Windows NT. See
240 windows-NT/README for details.
242 * The CVSROOT variable specification has changed to support more
243 access methods. In addition to "pserver," "server" (internal rsh
244 client), "ext" (external rsh client), "kserver" (kerberos), and
245 "local" (local filesystem access) can now be specified. For more
246 details on each method, see cvs.texinfo (there is an index entry for
247 :local: and each of the other access methods).
249 * The "login" command no longer prompts the user for username and
250 hostname, since one will have to provide that information via the `-d'
251 flag or by setting CVSROOT.
253 Changes from 1.7 to 1.8:
255 * New "cvs annotate" command to display the last modification for each
256 line of a file, with the revision number, user checking in the
257 modification, and date of the modification. For more information see
258 the `annotate' node in cvs.texinfo.
260 * The cvsinit shell script has been replaced by a cvs init command.
261 The cvs init command creates some example administrative files which
262 are similar to the files found in the examples directory (and copied
263 by cvsinit) in previous releases.
265 * Added the patterns *.olb *.exe _$* *$ to default ignore list.
267 * There is now a $USER internal variable for *info files.
269 * There is no longer a separate `mkmodules' program; the functionality
270 is now built into `cvs'. If upgrading an old repository, it is OK to
271 leave in the lines in the modules file which run mkmodules (the
272 mkmodules actions will get done twice, but that is harmless); you will
273 probably want to remove them once you are no longer using the old CVS.
275 * One can now specify user variables in *info files via the
276 ${=varname} syntax; there is a -s global option to set them. See the
277 Variables node in cvs.texinfo for details.
279 Changes from 1.6 to 1.7:
281 * The default ignore list has changed slightly: *.obj has been added
282 and CVS* has been changed to CVS CVS.adm.
284 * CVS now supports password authentication when accessing remote
285 repositories; this is useful for sites that can't use rsh (because of
286 a firewall, for example), and also don't have kerberos. See node
287 "Password authenticated" (in "Remote repositories", in
288 doc/cvs.texinfo) for more details. Note: This feature requires both
289 the client and server to be upgraded.
291 * Using the -kb option to specify binary files now works--most cases
292 did not work before. See the "Binary files" section of
293 doc/cvs.texinfo for details.
295 * New developer communication features. See the "Watches" section of
296 doc/cvs.texinfo for details.
298 * RCS keyword "Name" supported for "cvs update -r <tag>" and "cvs
301 * If there is a group whose name matches a compiled in value which
302 defaults to "cvsadmin", only members of that group can use "cvs
303 admin". This replaces the CVS_NOADMIN option.
305 * CVS now sets the modes of files in the repository based on the
306 CVSUMASK environment variable or a compiled in value defaulting to
307 002. This way other developers will be able to access the files in
308 the repository regardless of the umask of the developer creating them.
310 * The command names in .cvsrc now match the official name of the
311 command, not the one (possibly an alias) by which it was invoked. If
312 you had previously relied on "cvs di" and "cvs diff" using different
313 options, instead use a shell function or alias (for example "alias
314 cvsdi='cvs diff -u'"). You also can specify global CVS options (like
315 "-z") using the command name "cvs".
317 Changes from 1.5 to 1.6:
319 * Del updated the man page to include all of the new features
322 * "cvs tag" now supports a "-r | -D" option for tagging an already
323 tagged revision / specific revision of a file.
325 * There is a "taginfo" file in CVSROOT that supports filtering and
326 recording of tag operations.
328 * Long options support added, including --help and --version options.
330 * "cvs release" no longer cares whether or not the directory being
331 released has an entry in the `modules' file.
333 * The modules file now takes a -e option which is used instead of -o
334 for "cvs export". If your modules file has a -o option which you want
335 to be used for "cvs export", change it to specify -e as well as -o.
337 * "cvs export" now takes a -k option to set RCS keyword expansion.
338 This way you can export binary files. If you want the old behavior,
339 you need to specify -kv.
341 * "cvs update", "cvs rdiff", "cvs checkout", "cvs import", "cvs
342 release", "cvs rtag", and "cvs tag" used to take -q and -Q options
343 after the command name (e.g. "cvs update -q"). This was confusing
344 because other commands, such as "cvs ci", did not. So the options
345 after the command name have been removed and you must now specify, for
346 example, "cvs -q update", which has been supported since CVS 1.3.
348 * New "wrappers" feature. This allows you to set a hook which
349 transforms files on their way in and out of cvs (apparently on the
350 NeXT there is some particular usefulness in tarring things up in the
351 repository). It also allows you to declare files as merge-by-copy
352 which means that instead of trying to merge the file, CVS will merely
353 copy the new version. There is a CVSROOT/cvswrappers file and an
354 optionsl ~/.cvswrappers file to support this feature.
356 * You can set CVSROOT to user@host:dir, not just host:dir, if your
357 username on the server host is different than on the client host.
359 * VISUAL is accepted as well as EDITOR.
361 * $CVSROOT is expanded in *info files.
363 Changes from 1.4A2 to 1.5:
365 * Remote implementation. This is very helpful when collaborating on a
366 project with someone across a wide-area network. This release can
367 also be used locally, like other CVS versions, if you have no need for
370 Here are some of the features of the remote implementation:
371 - It uses reliable transport protocols (TCP/IP) for remote repository
372 access, not NFS. NFS is unusable over long distances (and sometimes
373 over short distances)
374 - It transfers only those files that have changed in the repository or
375 the working directory. To save transmission time, it will transfer
376 patches when appropriate, and can compress data for transmission.
377 - The server never holds CVS locks while waiting for a reply from the client;
378 this makes the system robust when used over flaky networks.
380 The remote features are documented in doc/cvsclient.texi in the CVS
381 distribution, but the main doc file, cvs.texinfo, has not yet been
382 updated to include the remote features.
384 * Death support. See src/README-rm-add for more information on this.
386 * Many speedups, especially from jtc@cygnus.com.
388 * CVS 1.2 compatibility code has been removed as a speedup. If you
389 have working directories checked out by CVS 1.2, CVS 1.3 or 1.4A2 will
390 try to convert them, but CVS 1.5 and later will not (if the working
391 directory is up to date and contains no extraneous files, you can just
392 remove it, and then check out a new working directory). Likewise if
393 your repository contains a CVSROOT.adm directory instead of a CVSROOT
394 directory, you need to rename it.
396 Fri Oct 21 20:58:54 1994 Brian Berliner <berliner@sun.com>
398 * Changes between CVS 1.3 and CVS 1.4 Alpha-2
400 * A new program, "cvsbug", is provided to let you send bug reports
401 directly to the CVS maintainers. Please use it instead of sending
402 mail to the info-cvs mailing list. If your build fails, you may
403 have to invoke "cvsbug" directly from the "src" directory as
406 * A new User's Guide and Tutorial, written by Per Cederqvist
407 <ceder@signum.se> of Signum Support. See the "doc" directory. A
408 PostScript version is included as "doc/cvs.ps".
410 * The Frequesntly Asked Questions file, FAQ, has been added to the
411 release. Unfortunately, its contents are likely out-of-date.
413 * The "cvsinit" shell script is now installed in the $prefix/bin
414 directory like the other programs. You can now create new
415 CVS repositories with great ease.
417 * Index: lines are now printed on output from 'diff' and 'rdiff',
418 in order to facilitate application of patches to multiple subdirs.
420 * Support for a ~/.cvsrc file, which allows you to specify options
421 that are always supposed to be given to a specific command. This
422 feature shows the non-orthogonality of the option set, since while
423 there may be an option to turn something on, the option to turn
424 that same thing off may not exist.
426 * You can now list subdirectories that you wish to ignore in a
427 modules listing, such as:
429 gcc -a gnu/gcc, !gnu/gcc/testsuites
431 which will check out everything underneath gnu/gcc, except
432 everything underneath gnu/gcc/testsuites.
434 * It is now much harder to accidentally overwrite an existing tag
435 name, since attempting to move a tag name will result in a error,
436 unless the -F (force) flag is given to the tag subcommands.
438 * Better error checking on matching of the repository used to
439 check code out from against the repository the current cvs
440 commnands would use. (Thanks to Mark Baushke <mdb@cisco.com>)
442 * Better support for sites with multiple CVSROOT repositories has
443 been contributed. The file "CVS/Root" in your working directory
444 is created to hold the full path to the CVS repository and a
445 simple check is made against your current CVSROOT setting.
447 * You can now specify an RCS keyword substitution value when you
448 import files into the repository.
450 * Uses a much newer version of Autoconf, and conforms to the GNU
451 coding standards much more closely. No, it still doesn't have
454 * Code cleanup. Many passes through gcc -Wall helped to identify
455 a number of questionable constructs. Most arbitrary length limits
458 * Profiling to determine bottlenecks helped to identify the best
459 places to spend time speeding up the code, which was then done. A
460 number of performance enhancements in filename matching have sped
463 * Many more contributions have been added to the "contrib"
464 directory. See the README file in that directory for more
467 * "cvs commit" will try harder to not change the file's
468 modification time after the commit. If the file does not change
469 as a result of the commit operation, CVS will preserve the
470 original modification time, thus speeding up future make-type
473 * "cvs commit" now includes any removed files in the (optional)
474 pre-commit checking program that may be invoked. Previously, only
475 added and modified files were included.
477 * It is now possible to commit a file directly onto the trunk at a
478 specific revision level by doing "cvs commit -r3.0 file.c", where
479 "3.0" specifies the revision you wish to create. The file must be
480 up-to-date with the current head of the trunk for this to succeed.
482 * "cvs commit" will now function with a pre-commit program that
483 has arguments specified in the "commitinfo" file.
485 * The "mkmodules" program will now look within the
486 $CVSROOT/CVSROOT/checkoutlist" file for any additional files that
487 should be automatically checked out within CVSROOT; mkmodules also
488 tries harder to preserve any execute bits the files may have
491 * "cvs diff" is much more accurate about its exit status now. It
492 now returns the maximum exit status of any invoked diff.
494 * The "-I !" option is now supported for the import and update
495 commands correctly. It will properly clear the ignore list now.
497 * Some problems with "cvs import" handling of .cvsignore have been
498 fixed; as well, some rampant recursion problems with import have
501 * "cvs rdiff" (aka "cvs patch") now tries to set the modify time
502 of any temporary files it uses to match those specified for the
503 particular revision. This allows a more accurate patch image to
506 * "cvs status" has improved revision descriptions. "Working
507 revision" is used for the revision of the working file that you
508 edit directly; "Repository revision" is the revision of the file
509 with the $CVSROOT source repository. Also, the output is clearer
510 with regard to sticky and branch revisions.
512 * CVS no longer dumps core when given a mixture of directories and
513 files in sub-directories (as in "cvs ci file1 dir1/file2").
514 Instead, arguments are now clumped into their respective directory
515 and operated on in chunks, together.
517 * If the CVSEDITOR environment variable is set, that editor is
518 used for log messages instead of the EDITOR environment variable.
519 This makes it easy to substitute intelligent programs to make more
520 elaborate log messages. Contributed by Mark D Baushke
523 * Command argument changes:
524 cvs: The "-f" option has been added to ignore
526 commit: Renamed the "-f logfile" option to the
527 "-F logfile" option. Added the "-f"
528 option to force a commit of the specified
529 files (this disables recursion).
530 history: Added "-t timezone" option to force any
531 date-specific output into the specified
533 import: Added "-d" option to use the file's
534 modification time as the time of the
535 import. Added "-k sub" option to set the
536 default RCS keyword substitution mode for
538 remove: Added "-f" option to force the file's
539 automatic removal if it still exists in
540 the working directory (use with caution).
541 rtag: Added "-F" option to move the tag if it
542 already exists -- new default is to NOT
543 move tags automatically.
544 tag: Added "-F" option to move the tag if it
545 already exists -- new default is to NOT
546 move tags automatically.
548 Tue Apr 7 15:55:25 1992 Brian Berliner (berliner at sun.com)
550 * Changes between CVS 1.3 Beta-3 and official CVS 1.3!
552 * A new shell script is provided, "./cvsinit", which can be run at
553 install time to help setup your $CVSROOT area. This can greatly
554 ease your entry into CVS usage.
556 * The INSTALL file has been updated to include the machines on
557 which CVS has compiled successfully. I think CVS 1.3 is finally
558 portable. Thanks to all the Beta testers!
560 * Support for the "editinfo" file was contributed. This file
561 (located in $CVSROOT/CVSROOT) can be used to specify a special
562 "editor" to run on a per-directory basis within the repository,
563 instead of the usual user's editor. As such, it can verify that
564 the log message entered by the user is of the appropriate form
565 (contains a bugid and test validation, for example).
567 * The manual pages cvs(1) and cvs(5) have been updated.
569 * The "mkmodules" command now informs you when your modules file
570 has duplicate entries.
572 * The "add" command now preserves any per-directory sticky tag when
573 you add a new directory to your checked-out sources.
575 * The "admin" command is now a fully recursive interface to the
576 "rcs" program which operates on your checked-out sources. It no
577 longer requires you to specify the full path to the RCS file.
579 * The per-file sticky tags can now be effectively removed with
580 "cvs update -A file", even if you had checked out the whole
581 directory with a per-directory sticky tag. This allows a great
582 deal of flexibility in managing the revisions that your checked-out
583 sources are based upon (both per-directory and per-file sticky
586 * The "cvs -n commit" command now works, to show which files are
587 out-of-date and will cause the real commit to fail, or which files
588 will fail any pre-commit checks. Also, the "cvs -n import ..."
589 command will now show you what it would've done without actually
592 * Doing "cvs commit modules" to checkin the modules file will no
593 properly run the "mkmodules" program (assuming you have setup your
594 $CVSROOT/CVSROOT/modules file to do so).
596 * The -t option in the modules file (which specifies a program to
597 run when you do a "cvs rtag" operation on a module) now gets the
598 symbolic tag as the second argument when invoked.
600 * When the source repository is locked by another user, that user's
601 login name will be displayed as the holder of the lock.
603 * Doing "cvs checkout module/file.c" now works even if
604 module/file.c is in the Attic (has been removed from main-line
607 * Doing "cvs commit */Makefile" now works as one would expect.
608 Rather than trying to commit everything recursively, it will now
609 commit just the files specified.
611 * The "cvs remove" command is now fully recursive. To schedule a
612 file for removal, all you have to do is "rm file" and "cvs rm".
613 With no arguments, "cvs rm" will schedule all files that have been
614 physically removed for removal from the source repository at the
617 * The "cvs tag" command now prints "T file" for each file that was
618 tagged by this invocation and "D file" for each file that had the
619 tag removed (as with "cvs tag -d").
621 * The -a option has been added to "cvs rtag" to force it to clean
622 up any old, matching tags for files that have been removed (in the
623 Attic) that may not have been touched by this tag operation. This
624 can help keep a consistent view with your tag, even if you re-use
627 Sat Feb 29 16:02:05 1992 Brian Berliner (berliner at sun.com)
629 * Changes between CVS 1.3 Beta-2 and CVS 1.3 Beta-3
631 * Many portability fixes, thanks to all the Beta testers! With any
632 luck, this Beta release will compile correctly on most anything.
633 Hey, what are we without our dreams.
635 * CVS finally has support for doing isolated development on a
636 branch off the current (or previous!) revisions. This is also
637 extremely nice for generating patches for previously released
638 software while development is progressing on the next release.
639 Here's an example of creating a branch to fix a patch with the 2.0
640 version of the "foo" module, even though we are already well into
643 % cvs rtag -b -rFOO_2_0 FOO_2_0_Patch foo
644 % cvs checkout -rFOO_2_0_Patch foo
649 A physical branch will be created in the RCS file only when you
650 actually commit the change. As such, forking development at some
651 random point in time is extremely light-weight -- requiring just a
652 symbolic tag in each file until a commit is done. To fork
653 development at the currently checked out sources, do:
655 % cvs tag -b Personal_Hack
656 % cvs update -rPersonal_Hack
660 Now, if you decide you want the changes made in the Personal_Hack
661 branch to be merged in with other changes made in the main-line
662 development, you could do:
664 % cvs commit # to make Personal_Hack complete
665 % cvs update -A # to update sources to main-line
666 % cvs update -jPersonal_Hack # to merge Personal_Hack
668 to update your checked-out sources, or:
670 % cvs checkout -jPersonal_Hack module
672 to checkout a fresh copy.
674 To support this notion of forked development, CVS reserves
675 all even-numbered branches for its own use. In addition, CVS
676 reserves the ".0" and ".1" branches. So, if you intend to do your
677 own branches by hand with RCS, you should use odd-numbered branches
678 starting with ".3", as in "1.1.3", "1.1.5", 1.2.9", ....
680 * The "cvs commit" command now supports a fully functional -r
681 option, allowing you to commit your changes to a specific numeric
682 revision or symbolic tag with full consistency checks. Numeric
683 tags are useful for bringing your sources all up to some revision
688 For symbolic tags, you can only commit to a tag that references a
689 branch in the RCS file. One created by "cvs rtag -b" or from
690 "cvs tag -b" is appropriate (see below).
692 * Roland Pesch <pesch@cygnus.com> and K. Richard Pixley
693 <rich@cygnus.com> were kind enough to contribute two new manual
694 pages for CVS: cvs(1) and cvs(5). Most of the new CVS 1.3 features
695 are now documented, with the exception of the new branch support
696 added to commit/rtag/tag/checkout/update.
698 * The -j options of checkout/update have been added. The "cvs join"
699 command has been removed.
701 With one -j option, CVS will merge the changes made between the
702 resulting revision and the revision that it is based on (e.g., if
703 the tag refers to a branch, CVS will merge all changes made in
704 that branch into your working file).
706 With two -j options, CVS will merge in the changes between the two
707 respective revisions. This can be used to "remove" a certain delta
708 from your working file. E.g., If the file foo.c is based on
709 revision 1.6 and I want to remove the changes made between 1.3 and
712 % cvs update -j1.5 -j1.3 foo.c # note the order...
714 In addition, each -j option can contain on optional date
715 specification which, when used with branches, can limit the chosen
716 revision to one within a specific date. An optional date is
717 specified by adding a colon (:) to the tag, as in:
719 -jSymbolic_Tag:Date_Specifier
721 An example might be what "cvs import" tells you to do when you have
722 just imported sources that have conflicts with local changes:
724 % cvs checkout -jTAG:yesterday -jTAG module
726 which tells CVS to merge in the changes made to the branch
727 specified by TAG in the last 24 hours. If this is not what is
728 intended, substitute "yesterday" for whatever format of date that
729 is appropriate, like:
731 % cvs checkout -jTAG:'1 week ago' -jTAG module
733 * "cvs diff" now supports the special tags "BASE" and "HEAD". So,
736 % cvs diff -u -rBASE -rHEAD
738 will effectively show the changes made by others (in unidiff
739 format) that will be merged into your working sources with your
740 next "cvs update" command. "-rBASE" resolves to the revision that
741 your working file is based on. "-rHEAD" resolves to the current
742 head of the branch or trunk that you are working on.
744 * The -P option of "cvs checkout" now means to Prune empty
745 directories, as with "update". The default is to not remove empty
746 directories. However, if you do "checkout" with any -r options, -P
747 will be implied. I.e., checking out with a tag will cause empty
748 directories to be pruned automatically.
750 * The new file INSTALL describes how to install CVS, including
751 detailed descriptions of interfaces to "configure".
753 * The example loginfo file in examples/loginfo has been updated to
754 use the perl script included in contrib/log.pl. The nice thing
755 about this log program is that it records the revision numbers of
756 your change in the log message.
758 Example files for commitinfo and rcsinfo are now included in the
761 * All "#if defined(__STDC__) && __STDC__ == 1" lines have been
762 changed to be "#if __STDC__" to fix some problems with the former.
764 * The lib/regex.[ch] files have been updated to the 1.3 release of
765 the GNU regex package.
767 * The ndbm emulation routines included with CVS 1.3 Beta-2 in the
768 src/ndbm.[ch] files has been moved into the src/myndbm.[ch] files
769 to avoid any conflict with the system <ndbm.h> header file. If
770 you had a previous CVS 1.3 Beta release, you will want to "cvs
771 remove ndbm.[ch]" form your copy of CVS as well.
773 * "cvs add" and "cvs remove" are a bit more verbose, telling you
774 what to do to add/remove your file permanently.
776 * We no longer mess with /dev/tty in "commit" and "add".
778 * More things are quiet with the -Q option set.
780 * New src/config.h option: If CVS_BADROOT is set, CVS will not
781 allow people really logged in as "root" to commit changes.
783 * "cvs diff" exits with a status of 0 if there were no diffs, 1 if
784 there were diffs, and 2 if there were errors.
786 * "cvs -n diff" is now supported so that you can still run diffs
787 even while in the middle of committing files.
789 * Handling of the CVS/Entries file is now much more robust.
791 * The default file ignore list now includes "*.so".
793 * "cvs import" did not expand '@' in the log message correctly. It
794 does now. Also, import now uses the ignore file facility
797 Import will now tell you whether there were conflicts that need to
798 be resolved, and how to resolve them.
800 * "cvs log" has been changed so that you can "log" things that are
801 not a part of the current release (in the Attic).
803 * If you don't change the editor message on commit, CVS now prompts
806 !)reuse this message unchanged for remaining dirs
808 which allows you to tell CVS that you have no intention of changing
809 the log message for the remainder of the commit.
811 * It is no longer necessary to have CVSROOT set if you are using
812 the -H option to get Usage information on the commands.
814 * Command argument changes:
815 checkout: -P handling changed as described above.
816 New -j option (up to 2 can be specified)
817 for doing rcsmerge kind of things on
819 commit: -r option now supports committing to a
820 numeric or symbolic tags, with some
821 restrictions. Full consistency checks will
823 Added "-f logfile" option, which tells
824 commit to glean the log message from the
825 specified file, rather than invoking the
827 rtag: Added -b option to create a branch tag,
828 useful for creating a patch for a previous
829 release, or for forking development.
830 tag: Added -b option to create a branch tag,
831 useful for creating a patch for a previous
832 release, or for forking development.
833 update: New -j option (up to 2 can be specified)
834 for doing rcsmerge kind of things on
837 Thu Jan 9 10:51:35 MST 1992 Jeff Polk (polk at BSDI.COM)
839 * Changes between CVS 1.3 Beta-1 and CVS 1.3 Beta-2
841 * Thanks to K. Richard Pixley at Cygnus we now have function
842 prototypes in all the files
844 * Some small changes to configure for portability. There have
845 been other portability problems submitted that have not been fixed
846 (Brian will be working on those). Additionally all __STDC__
847 tests have been modified to check __STDC__ against the constant 1
848 (this is what the Second edition of K&R says must be true).
850 * Lots of additional error checking for forked processes (run_exec)
851 (thanks again to K. Richard Pixley)
853 * Lots of miscellaneous bug fixes - including but certainly not
855 various commit core dumps
856 various update core dumps
857 bogus results from status with numeric sticky tags
858 commitprog used freed memory
859 Entries file corruption caused by No_Difference
860 commit to revision broken (now works if branch exists)
861 ignore file processing broken for * and !
862 ignore processing didn't handle memory reasonably
863 miscellaneous bugs in the recursion processor
864 file descriptor leak in ParseInfo
865 CVSROOT.adm->CVSROOT rename bug
868 * Reformatted all the code in src (with GNU indent) and then
869 went back and fixed prototypes, etc since indent gets confused. The
870 rationale is that it is better to do it sooner than later and now
871 everything is consistent and will hopefully stay that way.
872 The basic options to indent were: "-bad -bbb -bap -cdb -d0 -bl -bli0
873 -nce -pcs -cs -cli4 -di1 -nbc -psl -lp -i4 -ip4 -c41" and then
874 miscellaneous formatting fixes were applied. Note also that the
875 "-nfc1" or "-nfca" may be appropriate in files where comments have
876 been carefully formatted (e.g, modules.c).
878 Sat Dec 14 20:35:22 1991 Brian Berliner (berliner at sun.com)
880 * Changes between CVS 1.2 and CVS 1.3 Beta are described here.
882 * Lots of portability work. CVS now uses the GNU "configure"
883 script to dynamically determine the features provided by your
884 system. It probably is not foolproof, but it is better than
885 nothing. Please let me know of any portability problems. Some
886 file names were changed to fit within 14-characters.
888 * CVS has a new RCS parser that is much more flexible and
889 extensible. It should read all known RCS ",v" format files.
891 * Most of the commands now are fully recursive, rather than just
892 operating on the current directory alone. This includes "commit",
893 which makes it real easy to do an "atomic" commit of all the
894 changes made to a CVS hierarchy of sources. Most of the commands
895 also correctly handle file names that are in directories other than
896 ".", including absolute path names. Commands now accept the "-R"
897 option to force recursion on (though it is always the default now)
898 and the "-l" option to force recursion off, doing just "." and not
901 * CVS supports many of the features provided with the RCS 5.x
902 distribution - including the new "-k" keyword expansion options. I
903 recommend using RCS 5.x (5.6 is the current official RCS version)
904 and GNU diff 1.15 (or later) distributions with CVS.
906 * Checking out files with symbolic tags/dates is now "sticky", in
907 that CVS remembers the tag/date used for each file (and directory)
908 and will use that tag/date automatically on the next "update" call.
909 This stickyness also holds for files checked out with the the new
910 RCS 5.x "-k" options.
912 * The "cvs diff" command now recognizes all of the rcsdiff 5.x
913 options. Unidiff format is available by installing the GNU
914 diff 1.15 distribution.
916 * The old "CVS.adm" directories created on checkout are now called
917 "CVS" directories, to look more like "RCS" and "SCCS". Old CVS.adm
918 directories are automagically converted to CVS directories. The
919 old "CVSROOT.adm" directory within the source repository is
920 automagically changed into a "CVSROOT" directory as well.
922 * Symbolic links in the source repository are fully supported ONLY
923 if you use RCS 5.6 or later and (of course) your system supports
926 * A history database has been contributed which maintains the
927 history of certain CVS operations, as well as providing a wide array
930 * The "cvs" program has a "-n" option which can be used with the
931 "update" command to show what would be updated without actually
932 doing the update, like: "cvs -n update". All usage statements
933 have been cleaned up and made more verbose.
935 * The module database parsing has been rewritten. The new format
936 is compatible with the old format, but with much more
937 functionality. It allows modules to be created that grab pieces or
938 whole directories from various different parts of your source
939 repository. Module-relative specifications are also correctly
940 recognized now, like "cvs checkout module/file.c".
942 * A configurable template can be specified such that on a "commit",
943 certain directories can supply a template that the user must fill
944 before completing the commit operation.
946 * A configurable pre-commit checking program can be specified which
947 will run to verify that a "commit" can happen. This feature can be
948 used to restrict certain users from changing certain pieces of the
949 source repository, or denying commits to the entire source
952 * The new "cvs export" command is much like "checkout", but
953 establishes defaults suitable for exporting code to others (expands
954 out keywords, forces the use of a symbolic tag, and does not create
955 "CVS" directories within the checked out sources.
957 * The new "cvs import" command replaces the deprecated "checkin"
958 shell script and is used to import sources into CVS control. It is
959 also much faster for the first-time import. Some algorithmic
960 improvements have also been made to reduce the number of
961 conflicting files on next-time imports.
963 * The new "cvs admin" command is basically an interface to the
964 "rcs" program. (Not yet implemented very well).
966 * Signal handling (on systems with BSD or POSIX signals) is much
967 improved. Interrupting CVS now works with a single interrupt!
969 * CVS now invokes RCS commands by direct fork/exec rather than
970 calling system(3). This improves performance by removing a call to
971 the shell to parse the arguments.
973 * Support for the .cvsignore file has been contributed. CVS will
974 now show "unknown" files as "? filename" as the result of an "update"
975 command. The .cvsignore file can be used to add files to the
976 current list of ignored files so that they won't show up as unknown.
978 * Command argument changes:
979 cvs: Added -l to turn off history logging.
980 Added -n to show what would be done without actually
982 Added -q/-Q for quiet and really quiet settings.
983 Added -t to show debugging trace.
984 add: Added -k to allow RCS 5.x -k options to be specified.
985 admin: New command; an interface to rcs(1).
986 checkout: Added -A to reset sticky tags/date/options.
987 Added -N to not shorten module paths.
988 Added -R option to force recursion.
989 Changed -p (prune empty directories) to -P option.
990 Changed -f option; forcing tags match is now default.
991 Added -p option to checkout module to standard output.
992 Added -s option to cat the modules db with status.
993 Added -d option to checkout in the specified directory.
994 Added -k option to use RCS 5.x -k support.
995 commit: Removed -a option; use -l instead.
997 Added -l option to disable recursion.
998 Added -R option to force recursion.
999 If no files specified, commit is recursive.
1000 diff: Now recognizes all RCS 5.x rcsdiff options.
1001 Added -l option to disable recursion.
1002 Added -R option to force recursion.
1003 history: New command; displays info about CVS usage.
1004 import: Replaces "checkin" shell script; imports sources
1005 under CVS control. Ignores files on the ignore
1006 list (see -I option or .cvsignore description above).
1007 export: New command; like "checkout", but w/special options
1008 turned on by default to facilitate exporting sources.
1009 join: Added -B option to join from base of the branch;
1010 join now defaults to only joining with the top two
1011 revisions on the branch.
1012 Added -k option for RCS 5.x -k support.
1013 log: Supports all RCS 5.x options.
1014 Added -l option to disable recursion.
1015 Added -R option to force recursion.
1016 patch: Changed -f option; forcing tags match is now default.
1017 Added -c option to force context-style diffs.
1018 Added -u option to support unidiff-style diffs.
1019 Added -V option to support RCS specific-version
1020 keyword expansion formats.
1021 Added -R option to force recursion.
1022 remove: No option changes. It's a bit more verbose.
1023 rtag: Equivalent to the old "cvs tag" command.
1024 No option changes. It's a lot faster for re-tag.
1025 status: New output formats with more information.
1026 Added -l option to disable recursion.
1027 Added -R option to force recursion.
1028 Added -v option to show symbolic tags for files.
1029 tag: Functionality changed to tag checked out files
1030 rather than modules; use "rtag" command to get the
1031 old "cvs tag" behaviour.
1032 update: Added -A to reset sticky tags/date/options.
1033 Changed -p (prune empty directories) to -P option.
1034 Changed -f option; forcing tags match is now default.
1035 Added -p option to checkout module to standard output.
1036 Added -I option to add files to the ignore list.
1037 Added -R option to force recursion.
1041 * Jeff Polk <polk@bsdi.com> rewrote most of the grody code of CVS
1042 1.2. He made just about everything dynamic (by using malloc),
1043 added a generic hashed list manager, re-wrote the modules database
1044 parsing in a compatible - but extended way, generalized directory
1045 hierarchy recursion for virtually all the commands (including
1046 commit!), generalized the loginfo file to be used for pre-commit
1047 checks and commit templates, wrote a new and flexible RCS parser,
1048 fixed an uncountable number of bugs, and helped in the design of
1049 future CVS features. If there's anything gross left in CVS, it's
1052 * David G. Grubbs <dgg@odi.com> contributed the CVS "history" and
1053 "release" commands. As well as the ever-so-useful "-n" option of
1054 CVS which tells CVS to show what it would do, without actually
1055 doing it. He also contributed support for the .cvsignore file.
1057 * Paul Sander, HaL Computer Systems, Inc. <paul@hal.com> wrote and
1058 contributed the code in lib/sighandle.c. I added support for
1059 POSIX, BSD, and non-POSIX/non-BSD systems.
1061 * Free Software Foundation contributed the "configure" script and
1062 other compatibility support in the "lib" directory, which will help
1063 make CVS much more portable.
1065 * Many others have contributed bug reports and enhancement requests.
1066 Some have even submitted actual code which I have not had time yet
1067 to integrate into CVS. Maybe for the next release.
1069 * Thanks to you all!
1071 Wed Feb 6 10:10:58 1991 Brian Berliner (berliner at sun.com)
1073 * Changes from CVS 1.0 Patchlevel 1 to CVS 1.0 Patchlevel 2; also
1074 known as "Changes from CVS 1.1 to CVS 1.2".
1076 * Major new support with this release is the ability to use the
1077 recently-posted RCS 5.5 distribution with CVS 1.2. See below for
1078 other assorted bug-fixes that have been thrown in.
1080 * ChangeLog (new): Added Emacs-style change-log file to CVS 1.2
1081 release. Chronological description of changes between release.
1083 * README: Small fixes to installation instructions. My email
1084 address is now "berliner@sun.com".
1086 * src/Makefile: Removed "rcstime.h". Removed "depend" rule.
1088 * src/partime.c: Updated to RCS 5.5 version with hooks for CVS.
1089 * src/maketime.c: Updated to RCS 5.5 version with hooks for CVS.
1090 * src/rcstime.h: Removed from the CVS 1.2 distribution.
1091 Thanks to Paul Eggert <eggert@twinsun.com> for these changes.
1093 * src/checkin.csh: Support for RCS 5.5 parsing.
1094 Thanks to Paul Eggert <eggert@twinsun.com> for this change.
1096 * src/collect_sets.c (Collect_Sets): Be quieter if "-f" option is
1097 specified. When checking out files on-top-of other files that CVS
1098 doesn't know about, run a diff in the hopes that they are really
1099 the same file before aborting.
1101 * src/commit.c (branch_number): Fix for RCS 5.5 parsing.
1102 Thanks to Paul Eggert <eggert@twinsun.com> for this change.
1104 * src/commit.c (do_editor): Bug fix - fprintf missing argument
1105 which sometimes caused core dumps.
1107 * src/modules.c (process_module): Properly NULL-terminate
1108 update_dir[] in all cases.
1110 * src/no_difference.c (No_Difference): The wrong RCS revision was
1111 being registered in certain (strange) cases.
1113 * src/patch.c (get_rcsdate): New algorithm. No need to call
1114 maketime() any longer.
1115 Thanks to Paul Eggert <eggert@twinsun.com> for this change.
1117 * src/patchlevel.h: Increased patch level to "2".
1119 * src/subr.c (isdir, islink): Changed to compare stat mode bits
1122 * src/tag.c (tag_file): Added support for following symbolic links
1123 that are in the master source repository when tagging. Made tag
1124 somewhat quieter in certain cases.
1126 * src/update.c (update_process_lists): Unlink the user's file if it
1127 was put on the Wlist, meaning that the user's file is not modified
1128 and its RCS file has been removed by someone else.
1130 * src/update.c (update): Support for "cvs update dir" to correctly
1131 just update the argument directory "dir".
1133 * src/cvs.h: Fixes for RCS 5.5 parsing.
1134 * src/version_number.c (Version_Number): Fixes for parsing RCS 5.5
1135 and older RCS-format files.
1136 Thanks to Paul Eggert <eggert@twinsun.com> for these changes.
1138 * src/version_number.c (Version_Number): Bug fixes for "-f" option.
1139 Bug fixes for parsing with certain branch numbers. RCS
1140 revision/symbol parsing is much more solid now.
1142 Wed Feb 14 10:01:33 1990 Brian Berliner (berliner at sun.com)
1144 * Changes from CVS 1.0 Patchlevel 0 to CVS 1.0 Patchlevel 1; also
1145 known as "Changes from CVS 1.0 to CVS 1.1".
1147 * src/patch.c (get_rcsdate): Portability fix. Replaced call to
1148 timelocal() with call to maketime().
1150 Mon Nov 19 23:15:11 1990 Brian Berliner (berliner at prisma.com)
1152 * Sent CVS 1.0 release to comp.sources.unix moderator and FSF.
1154 * Special thanks to Dick Grune <dick@cs.vu.nl> for his work on the
1155 1986 version of CVS and making it available to the world. Dick's
1156 version is available on uunet.uu.net in the
1157 comp.sources.unix/volume6/cvs directory.
