6 * Thanks to Stefan Esser & Sebastian Krahmer, several potential security
7 problems have been fixed. The ones which were considered dangerous enough
8 to catalogue were assigned issue numbers CAN-2004-0416, CAN-2004-0417, &
9 CAN-2004-0418 by the Common Vulnerabilities and Exposures Project. Please
10 see <http://www.cve.mitre.org> for more information.
12 * A potential buffer overflow vulnerability in the server has been fixed.
13 This addresses the Common Vulnerabilities and Exposures Project's issue
14 #CAN-2004-0414. Please see <http://www.cve.mitre.org> for more information.
16 Changes from 1.11.15 to 1.11.16:
17 ********************************
21 * A potential buffer overflow vulnerability in the server has been fixed.
22 Prior to this patch, a malicious client could potentially use carefully
23 crafted server requests to run arbitrary programs on the CVS server machine.
24 This addresses the Common Vulnerabilities and Exposures Project's issue
25 #CAN-2004-0396. Please see <http://www.cve.mitre.org> for more information.
29 * The Microsoft Visual C++ workspace and project files have been repaired and
30 regenerated with MSVC++ 6.0.
32 * The cvs.1 man page is now generated automatically from a section of the CVS
35 * Thanks to a report from Mark Andrews at the Internet Systems Consortium, the
36 :ext: connection method no longer relies on a transparent transport that uses
37 an argument processor that can handle arbitrary ordering of options and other
38 arguments when using a username other than the caller's.
40 * Thanks to Ken Raeburn at MIT, directory deletion, whether via `cvs release'
41 or empty directory pruning, now works on network shares under Windows XP.
43 Changes from 1.11.14 to 1.11.15:
44 ********************************
46 SERVER SECURITY ISSUES
48 * Piped checkouts of paths above $CVSROOT no longer work. Previously, clients
49 could have requested the contents of RCS archive files anywhere on a CVS
50 server. This addresses CVE issue CAN-2004-0405. Please see
51 <http://www.cve.mitre.org> for more information.
53 CLIENT SECURITY ISSUES
55 * Clients now check paths from the server to verify that they are within one of
56 the sandboxes the user requested be updated. Previously, a trojan server
57 could have written or overwritten files anywhere the user had access,
58 presenting a serious security risk. This addresses CVE issue CAN-2004-1080.
59 Please see <http://www.cve.mitre.org> for more information.
63 * Method options (used by WinCVS & CVS 1.12.7+) in CVSROOTs are ignored.
65 * Configure no longer checks the $TMPDIR, $TMP, & $TEMP variables to set the
66 default temporary directory.
68 * CVS on Cygwin correctly handles X:\ style paths.
70 * Import now uses backslash rather than slash on Windows when checking for
71 "CVS" directories to ignore in import commands.
73 * Relative paths containing up-references (`..') should now work in
74 client/server mode (client fix).
76 * A race condition between the ordering of messages from CVS and messages from
77 called scripts in client/server mode has been removed (server fix).
79 * Resurrected files now get their modes and timestamps set correctly and a
80 longstanding bug involving resurrection of an uncommitted removal has been
83 * Some resurrection (cvs add) status messages have changed slightly.
85 * `cvs release' now works with Kerberos or GSSAPI encryption enabled (server
88 * File resurrection from a previously existing revision no longer just reports
89 that it works (server fix).
91 * Misc error & status message corrections.
93 * Diffing of locally added files against arbitrary revisions in an RCS archive
94 is now allowed when a file of the same name exists or used to exist on some
97 * Misc documentation fixes.
99 Changes from 1.11.13 to 1.11.14:
100 ********************************
104 * Imports will now always ignore directories and files named `CVS' to avoid
105 violating assumptions made by other parts of CVS.
107 * A problem with `cvs release' of subdirs that could corrupt CVS/Entries files
108 has been fixed (client/server).
110 * The CVS server's protocol check for unused data from the client is no longer
111 called automatically at program exit in order to avoid potential recursive
112 calls to error when the first close is due to memory allocation or similar
113 problems that cause calls to error() to fail. The check is still made when
114 the server program exits normally.
116 * The spec file has been updated to work with more recent versions of RPM.
118 * Several memory leaks have been plugged (client/server).
122 * Misc cosmetic, readability, and commenting fixes.
124 Changes from 1.11.12 to 1.11.13:
125 ********************************
129 * Several memory leaks have been plugged.
131 * Thanks to Ville Skyttä the man page has a few less spelling errors and is
132 slightly more accurate.
134 * An unlikely potential segfault when using the :fork: connection method has
137 * The CVS server has had the protocol check for unused data from the client
140 * A fix has been included that should avoid a very rare race condition that
141 could cause a CVS server to exit with a "broken pipe" message.
143 * A minor problem with the nmake build file that was preventing the source from
144 compiling under Windows has been fixed.
146 * Tests have been added to the test suite.
150 * Misc cosmetic, readability, and commenting fixes.
152 Changes from 1.11.11 to 1.11.12:
153 ********************************
157 * Infinite alias loops in the modules file are now checked for and avoided.
159 * Clients on case insensitive systems now preserve the case of directories in
160 CVS/Entries, in addition to files, for use in communications with the CVS
163 * Some previously untested behavior is now being tested.
165 * Server support for case insensitive clients has been removed in favor of the
166 server relying on the client to preserve the case of checked out files, as
167 per the CVS client/server protocol spec. This is not as drastic as it may
168 sound, as all of the current tests still pass without modification when run
169 from a case insensitive client to a case sensitive server. This change
170 disables little previous functionality, enables access to more of the
171 possible namespace to users on systems with case insensitive file systems,
172 fixes a few bugs, and in the end this should provide a major stability
175 * Thanks to Ville Skyttä the man page is a bit more accurate.
177 * Thanks to Ville Skyttä some unused variables were removed from the log_accum
178 Perl script in contrib.
180 * Thanks to Alexey Mahotkin, a bug that prevented CVS from being compiled with
181 Kerberos 4 authentication enabled has been fixed.
183 * A minor bug that caused CVS to fail to report an inifinte alias loop in the
184 modules file when portions of the alias definition contained trailing slashes
187 * A bug in the gzip code that could cause heap corruption and segfaults in CVS
188 servers talking to clients less than 1.8 and some modern third-party CVS
189 clients has been fixed.
191 * mktemp.sh is now included with the source distribution so that the rcs2log
192 and cvsbug executables may be run on systems which do not contain an
193 implementation of mktemp.
195 * Misc documentation fixes.
197 Changes from 1.11.10 to 1.11.11:
198 ********************************
200 SERVER SECURITY ISSUES
202 * pserver can no longer be configured to run as root via the
203 $CVSROOT/CVSROOT/passwd file, so if your passwd file is compromised, it no
204 longer leads directly to a root hack. Attempts to root will also be logged
207 Changes from 1.11.9 to 1.11.10:
208 *******************************
210 SERVER SECURITY ISSUES
212 * Malformed module requests could cause the CVS server to attempt to create
213 directories and possibly files at the root of the filesystem holding the CVS
214 repository. Filesystem permissions usually prevent the creation of these
215 misplaced directories, but nevertheless, the CVS server now rejects the
220 * Case insensitive clients using a case sensitive server can now use a
221 `cvs rm -f file; cvs add FILE' command sequence to add a file with the same
224 * CVSROOTs which contain a symlink to a real repository should work.
226 * The configure script now tests whether it is building CVS on a case
227 insensitive file system. If it is, CVS assumes that all file systems on this
228 platform will be case insensitive. This is useful for getting the case
229 insensitivity flag set correctly when compiling on Mac OS X and under Cygwin
230 on Windows. Autodetection can be overridden using the
231 --disable-case-sensitivity and --enable-case-sensitivity arguments to
234 * A behavior change in `cvs up -jrev1 -jrev2' for modified files with a base
235 revision of rev2 (ie, checked-out version matches rev2 and file has been
236 modified). The operation is no longer ignored and instead is passed to
237 diff3. This will potentially re-apply the diffs between the two revisions to
238 a modified local file. Status messages like from a standard merge have also
239 been added when the file would not or does not change due to this merge
240 request ("[file] already contains the changes between [revisions]...").
242 * A bug which could stop `cvs admin -mTAG:message' from recursing has been
245 * Misc documentation cleanup and fixes.
247 * Some of the contrib scripts, some of the documentation, and sanity.sh were
248 modified to use and recommend more portable commands rather than using and
249 recommending commands which were not compatible with the POSIX 1003.1-2001
254 * A new set of tests to test issues specific to case insensitive clients and
255 servers has also been added.
257 * Support has been added to the test suite to support testing over a :ext: link
258 to another machine, subject to some stringent requirements. This support can
259 be used, for instance, to test the operation of a case insensitive client
260 against a case sensitive server. Please see the comments in TEST and the
261 src/sanity.sh test script itself for more.
263 * We've standardized on Automake 1.7.9 to get a bug fix. See the note below
264 on the Autoconf upgrade for more details.
266 * We've standardized on Autoconf version 2.58 to avoid a bug and get at a few
267 new macros. Again, this should only really affect developers, though it is
268 possible that CVS will now compile on a few new platforms. Please see the
269 section of the INSTALL file about using the autotools if you are compiling
272 Changes from 1.11.8 to 1.11.9:
274 * CVS now knows how to report, as well as record, `P' record types.
276 * When running the `cvs history' command, clients will now send the
277 long-accepted `-e' option, for all records, rather than explicitly requesting
278 `P' record types, a request which servers prior to 1.11.7 will reject with a
281 * A problem with locating files requested by case insensitive clients which was
282 accidentally introduced in 1.11.6 as part of a fix for a data loss problem
283 involving `cvs add's from case insensitive clients has been fixed. The
284 relevant error message was `cvs [<command> aborted]: filE,v is ambiguous;
285 could mean FILE,v or file,v'.
287 * Attempts to use the global `-l' option, removed from both client and server
288 as of version 1.11.6, will now elicit a warning rather than a fatal error
291 Changes from 1.11.7 to 1.11.8:
293 * A problem in the CVS getpass library that could cause passwords to echo on
294 some systems has been fixed.
296 Changes from 1.11.6 to 1.11.7:
298 * A segfault that could occur in very rare cases where the stat of a file
299 failed during a diff has been fixed.
301 * Any user with write privleges to the CVSROOT/checkoutlist file could pass
302 arbitrary format strings directly through to a printf function. This was
303 probably bad and has been fixed. White space at the beginning of error strings
304 in checkoutlist is now ignored properly.
306 * In client/server mode, most messages from CVS now contain the actual
307 command name rather than the generic "server".
309 * A long-standing bug that prevented most client/server updates from being
310 logged in the history file has been fixed.
312 * Updates done via a patch ("P" status) are now logged in the history file
313 by default and the corresponding "P" history record type is now documented.
314 If you're setting the LogHistory option in your CVSROOT/config file, you may
315 want to add "P" to the list of record types.
317 * CVS now will always compile and its own getpass() function (originally from
318 GNULIB) in favor of any system one that may exist. This avoids some problems
319 with long passwords on some systems and updates us to POSIX.2 compliance, since
320 getpass() was removed from the POSIX.2 specification.
322 * A bug that allowed a write lock to be created in a directory despite
323 there being existing read locks when using LockDir in CVSROOT/config has
326 * A bug with short patches (`rdiff -s') which caused rdiff to sometimes report
327 differences that did not exist has been fixed.
329 * Some minor corrections were made to the diff code to keep diff & rdiff from
330 printing diff headers with empty change texts when two files have different
331 revision numbers but the same content.
333 * The global '-l' option, which suppressed history logging, has been removed
334 from both client and server.
336 Changes from 1.11.5 to 1.11.6:
338 * A warning message is now issued if an administrative file contains
339 more than one DEFAULT entry.
341 * An error running a verifymsg script (such as referencing an unset user
342 variable or the script not existing) now causes the verification to
345 * Errors in administrative files commands (like unset user variables)
346 are no longer reported unless the command is actually executed.
348 * When a file is initially checked out, its last access time is now set
349 to the current time rather than being set to the time the file was last
350 checked in like the modification time is.
352 * The Checkin.prog and Update.prog functionality has been removed. This
353 fuctionality previously allowed executables to be specified in the modules file
354 to be run at update and checkin time, but users could edit these files on a per
355 workspace basis, creating a security hole.
357 * contrib/rcs2log and src/cvsbug now use the BSD mktemp program to create
358 their temp files and directories on systems which provide it.
360 * Corrected the path in a failed write error message.
362 * Autoconf and Automake are no longer run automatically unless you run
363 configure with --enable-maintainer-mode. Accordingly, noautomake.sh is
364 no longer needed and has been removed.
366 * We've standardized on Automake version 1.7.5 and Autoconf version 2.57 to get
367 at a few new macros. Again, this should only really affect developers. See
368 the section of the INSTALL file about using the autotools if you are compiling
371 Changes from 1.11.4 to 1.11.5:
373 * Fixed a security hole in the CVS server by which users with read only access
374 could gain write access. This issue does not affect client builds. The
375 Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
376 name CAN-2003-0015 to this issue. See
377 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0015> for more
380 * Fixed some bugs where revision numbers starting with 0 (like 0.3)
381 weren't correctly handled. (CVS doesn't normally use such revision
382 numbers, but users may be able to force it to do so and old RCS files
385 Changes from 1.11.3 to 1.11.4:
387 * Some minor changes to allow the code to compile on Windows platforms.
389 Changes from 1.11.2 to 1.11.3:
391 * The tag/rtag code has been fixed to once again lock just a single
394 * There was a bug where certain error conditions could cause the server
395 to go into an infinite loop. There was also a bug that caused a
396 compressed connection from an older client to hang on shutdown. These
397 bugs have been fixed.
399 * Fixed a bug that caused the server to reject most watch commands.
401 * When waiting for another user's lock, the message timestamps are now
402 in UTC rather than the server's local time.
404 * The options.h file is no longer used. This fixes a bug that occurred when
405 1.11.2 was compiled on Windows platforms.
407 * We've standardized on Automake version 1.6.3 and Autoconf version 2.53.
408 They are cleaner, less bug prone, and will hopfully allow me to start updating
409 sanity.sh to use Autotest and Autoshell. Again, this should only really affect
410 developers. See the section of the INSTALL file about using the autotools if
411 you are compiling CVS yourself.
413 * Fixed a bug in the log/rlog code when a revision range crosses a
416 * Fixed a bug where filenames starting with - would be misinterpreted as
417 options when using client/server mode.
419 Changes from 1.11.1p1 to 1.11.2:
421 * There is a new feature, enabled by RereadLogAfterVerify in CVSROOT/config,
422 which tells CVS to reread the log message after running the verifymsg
423 script. This allows the verifymsg script to reformat or otherwise
424 modify the log message.
426 * The interpretation of revision ranges using :: in "log" and "rlog"
427 has changed: a::b now excludes the log message from revision a but
428 includes the log message from revision b. Also, revision ranges that
429 cross branch points should now work.
431 * zlib has been updated to version 1.4. There is a security advisory
432 out in regards to 1.3. This should fix that problem.
434 * The "log" and "rlog" commands now have a -S option to suppress the
435 header information when no revisions are selected.
437 * A serious error that allowed read-only users to tag files has been
440 * The "annotate" command will no longer annotate binary files unless
441 you specify the new -F option.
443 * The "tag" and "rtag" commands will no longer move or delete branch
444 tags unless you use the new -B option. (This prevents accidental
445 changes to branch tags that are hard to undo.)
447 * We've standardized on the 1.5 Automake release for the moment. Again, this
448 should only really affect developers. See the section of the INSTALL file
449 about using the autotools if you are compiling CVS yourself.
451 Changes from 1.11.1 to 1.11.1p1:
453 * Read only access was broken - now fixed.
455 Changes from 1.11 to 1.11.1:
457 * There was a locking bug in the tag/rtag code that could lose changes
458 made to a file while the tag operation was in progress. This has been
459 fixed, but all of the directories being tagged are now locked for the
460 entire duration of the tag operation rather than only one directory at a
463 * The "cvs diff" command now accepts the -y/--side=by-side and -T/
464 --initial-tab options. (To use these options with a remote repository,
465 both the client and the server must support them.)
467 * The expansion of the loginfo format string has changed slightly.
468 Previously, the expansion was surrounded by single quotes ('); if a file
469 name contained a single quote character, the string would not be parsed
470 as a single entity by the Unix shell (and it would not be possible to
471 parse it unambiguously). Now the expansion is surrounded by double
472 quotes (") and any embedded dollar signs ($), backticks (`), backslashes
473 (\), and double quotes are preceded by a backslash. This is parsed as a
474 single entity by the shell reguardless of content. This change should
475 not be noticable unless you're not using a Unix shell or you have
476 embedded the format string inside a double quoted string.
478 * There was a bug in the diff code which sometimes caused conflicts to
479 be flagged which shouldn't have been. This has been fixed.
481 * New "cvs rlog" and "cvs rannotate" commands have been added to get log
482 messages and annotations without having to have a checked-out copy.
484 * Exclusive revision ranges have been added to "cvs log" using ::
485 (similar to "cvs admin -o").
487 * The VMS client now accepts wildcards if you're running VMS 7.x.
489 * ZLIB has been updated to version 1.1.3, the most current version. This
490 includes mostly some optimizations and minor bug fixes.
492 * The ~/.cvspass file has a slightly modified format. CVSROOTs are now
493 stored in a new canonical form - hostnames are now case insensitive and
494 port numbers are always stored in the new format. Until a new login for
495 a particular CVSROOT is performed with the new version of CVS, new and
496 old versions of CVS should interoperate invisibly. After that point, an
497 extra login using the old version of CVS may be necessary to continue to
498 allow the new and old versions of CVS to interoperate using the same
499 ~/.cvspass file and CVSROOT. The exception to this rule occurs when the
500 CVSROOTs used with the different versions use case insensitively
501 different hostnames, for example, "empress", and "empress.2-wit.com".
503 * A password and a port number may now be specified in CVSROOT for
504 pserver connections. The new format is:
506 :pserver:[[user][:password]@]host[:[port]]/path
508 Note that passwords specified in a checkout command will be saved in the
509 clear in the CVS/Root file in each created directory, so this is not
510 recommended, except perhaps when accessing anonymous repositories or the
513 * The distribution has been converted to use Automake. This shouldn't
514 affect most users except to ease some portability concerns, but if you
515 are building from the repository and encounter problems with the
516 makefiles, you might try running ./noautomake.sh after a fresh update
519 Changes from 1.10 to 1.11:
521 * The "cvs update" command has a new -C option to get clean copies from
522 the repository, abandoning any local changes.
524 * The new "cvs version" command gives a short version message. If
525 the repository is remote, both the client and server versions are
528 * "cvs admin -t" now works correctly in client/server mode.
530 * The "cvs history" command output format has changed -- the date
531 now includes the year and is given is ISO 8601 format (yyyy-mm-dd).
532 Also, the new LogHistory option in CVSROOT/config can be used to
533 control what information gets recorded in the log file and code has
534 been added to record file removals.
536 * The buggy PreservePermissions code has been disabled.
538 * Anonymous read-only access can now be done without requiring a
539 password. On the server side, simply give that user (presumably
540 `anonymous') an empty password in the CVSROOT/passwd file, and then
541 any received password will authenticate successfully.
543 * There is a new access method :fork: which is similar to :local:
544 except that it is implemented via the CVS remote protocol, and thus
545 has a somewhat different set of quirks and bugs.
547 * The -d command line option no longer updates the CVS/Root file. For
548 one thing, the CVS 1.9/1.10 behavior never had updated CVS/Root in
549 subdirectories, and for another, it didn't seem that popular in
550 general. So this change restores the CVS 1.8 behavior (which is also
551 the CVS 1.9/1.10 behavior if the environment variable
552 CVS_IGNORE_REMOTE_ROOT is set; with this change,
553 CVS_IGNORE_REMOTE_ROOT no longer has any effect).
555 * It is now possible for a single CVS command to recurse into several
556 CVS roots. This includes roots which are located on several servers,
557 or which are both remote and local. CVS will make connections to as
558 many servers as necessary.
560 * It is now possible to put the CVS lock files in a directory
561 set by the new LockDir option in CVSROOT/config. The default
562 continues to be to put the lock files in the repository itself.
564 Changes from 1.9 to 1.10:
566 * A bug was discovered in the -t/-f wrapper support that can cause
567 serious data loss. Because of this (and also the fact that it doesn't
568 work at all in client/server mode), the -t/-f wrapper code has been
569 disabled until it can be fixed.
571 * There is a new feature, enabled by TopLevelAdmin in CVSROOT/config,
572 which tells CVS to modify the behavior of the "checkout" command. The
573 command now creates a CVS directory at the top level of the new
574 working directory, in addition to CVS directories created within
575 checked-out directories. See the Cederqvist for details.
577 * There is an optional set of features, enabled by PreservePermissions
578 in CVSROOT/config, which allow CVS to store unix-specific file
579 information such as permissions, file ownership, and links. See the
580 Cederqvist for details.
582 * One can now authenticate and encrypt using the GSSAPI network
583 security interface. For details see the Cederqvist's description of
584 specifying :gserver: in CVSROOT, and the -a global option.
586 * All access to RCS files is now implemented internally rather than by
587 calling RCS programs. The main user-visible consequence of this is
588 that there is no need to worry about making sure that CVS finds the
589 correct version of RCS. The -b global option and the RCSBIN setting
590 in CVSROOT/config are still accepted but don't do anything. The
591 $RCSBIN internal variable in administrative files is no longer
594 * There is a new syntax, "cvs admin -orev1::rev2", which collapses the
595 revisions between rev1 and rev2 without deleting rev1 or rev2
598 * There is a new administrative file CVSROOT/config which allows one
599 to specify miscellaneous aspects of CVS configuration. Currently
602 - SystemAuth, allows you to prevent pserver from checking for system
605 For more information see the "config" section of cvs.texinfo.
607 * When setting up the pserver server, one now must specify the
608 allowable CVSROOT directories in inetd.conf. See the Password
609 authentication server section of cvs.texinfo for details. Note that
610 this implies that everyone who is running a pserver server must edit
611 inetd.conf when upgrading their CVS.
613 * The client no longer needs an external patch program (assuming both
614 the client and the server have been updated to the new version).
616 * "cvs admin [options]" will now recurse. In previous versions of
617 CVS, it was an error and one needed to specify "cvs admin [options] ."
618 to recurse. This change brings admin in line with the other CVS
621 * New "logout" command to remove the password for a remote cvs
622 repository from the cvspass file.
624 * Read-only repository access is implemented for the
625 password-authenticated server (other access methods are just governed
626 by Unix file permissions, since they require login access to the
627 repository machine anyway). See the "Repository" section of
628 cvs.texinfo for details, including a discussion of security issues.
629 Note that the requirement that read-only users be able to create locks
630 and write the history file still applies.
632 * There is a new administrative file verifymsg which is like editinfo
633 but merely validates the message, rather than also getting it from the
634 user. It therefore works with client/server CVS or if one uses the -m
635 or -F options to commit. See the verifymsg section of cvs.texinfo for
638 * The %s format formerly accepted in loginfo has been extended to
639 formats such as %{sVv}, so that loginfo scripts have access to the
640 version numbers being changed. See the Loginfo section of cvs.texinfo
643 * The postscript documentation (doc/cvs.ps) shipped with CVS is now
644 formatted for US letter size instead of A4. This is not because we
645 consider this size "better" than A4, but because we believe that the
646 US letter version will print better on A4 paper than the other way
649 * The "cvs export" command is now logged in the history file and there
650 is a "cvs history -x E" command to select history file entries
653 * CVS no longer uses the CVS_PASSWORD environment variable. Storing
654 passwords in cleartext in an environment variable is a security risk,
655 especially since (on BSD variants) any user on the system can display
656 any process's environment using 'ps'. Users should use the 'cvs
657 login' command instead.
660 Changes from 1.8 to 1.9:
662 * Windows NT client should now work on Windows 95 as well.
664 * New option "--help-synonyms" prints a list of all recognized command
667 * The "log" command is now implemented internally rather than via the
668 RCS "rlog" program. The main user-visible consequence is that
669 symbolic branch names now work (for example "cvs log -rbranch1").
670 Also, the date formats accepted by -d have changed. They previously
671 had been a bewildering variety of poorly-documented date formats. Now
672 they are the same as the date formats accepted by the -D options to
673 the other CVS commands, which is also a (different) bewildering
674 variety of poorly-documented date formats, but at least we are
675 consistently bewildering :-).
677 * Encryption is now supported over a Kerberos client/server
678 connection. The new "-x" global option requests it. You must
679 configure with the --enable-encryption option in order to enable
682 * The format of the CVS commit message has changed slightly when
683 committing changes on a branch. The tag on which the commit is
684 ocurring is now reported correctly in all cases.
686 * New flag -k in wrappers allows you to specify the keyword expansion
687 mode for added files based on their name. For example, you can
688 specify that files whose name matches *.exe are binary by default.
689 See the Wrappers section of cvs.texinfo for more details.
691 * Remote CVS with the "-z" option now uses the zlib library (included
692 with CVS) to compress all communication between the client and the
693 server, rather than invoking gzip on each file separately. This means
694 that compression is better and there is no need for an external gzip
695 program (except to interoperate with older version of CVS).
697 * The "cvs rlog" command is deprecated and running it will print a
698 warning; use the synonymous "cvs log" command instead. It is
699 confusing for rlog to mean the same as log because some other CVS
700 commands are in pairs consisting of a plain command which operates on
701 a working directory and an "r" command which does not (diff/rdiff;
704 * "cvs diff" has a bunch of new options, mostly long options. Most of
705 these work only if rcsdiff and diff support them, and are named the
706 same as the corresponding options to diff.
708 * The -q and -Q command options to "cvs diff" were removed (use the
709 global options instead). This brings "cvs diff" into line with the
710 rest of the CVS commands.
712 * The "annotate" command can now be used to annotate a revision other
713 than the head revision on the trunk (see the -r, -D, and -f options in
714 the annotate node of cvs.texinfo for details).
716 * The "tag" command has a new option "-c" which checks that all files
717 are not locally modified before tagging.
719 * The -d command line option now overrides the cvsroot setting stored
720 in the CVS/Root file in each working directory, and specifying -d will
721 cause CVS/Root to be updated.
723 * Local (non-client/server) CVS now runs on Windows NT. See
724 windows-NT/README for details.
726 * The CVSROOT variable specification has changed to support more
727 access methods. In addition to "pserver," "server" (internal rsh
728 client), "ext" (external rsh client), "kserver" (kerberos), and
729 "local" (local filesystem access) can now be specified. For more
730 details on each method, see cvs.texinfo (there is an index entry for
731 :local: and each of the other access methods).
733 * The "login" command no longer prompts the user for username and
734 hostname, since one will have to provide that information via the `-d'
735 flag or by setting CVSROOT.
737 Changes from 1.7 to 1.8:
739 * New "cvs annotate" command to display the last modification for each
740 line of a file, with the revision number, user checking in the
741 modification, and date of the modification. For more information see
742 the `annotate' node in cvs.texinfo.
744 * The cvsinit shell script has been replaced by a cvs init command.
745 The cvs init command creates some example administrative files which
746 are similar to the files found in the examples directory (and copied
747 by cvsinit) in previous releases.
749 * Added the patterns *.olb *.exe _$* *$ to default ignore list.
751 * There is now a $USER internal variable for *info files.
753 * There is no longer a separate `mkmodules' program; the functionality
754 is now built into `cvs'. If upgrading an old repository, it is OK to
755 leave in the lines in the modules file which run mkmodules (the
756 mkmodules actions will get done twice, but that is harmless); you will
757 probably want to remove them once you are no longer using the old CVS.
759 * One can now specify user variables in *info files via the
760 ${=varname} syntax; there is a -s global option to set them. See the
761 Variables node in cvs.texinfo for details.
763 Changes from 1.6 to 1.7:
765 * The default ignore list has changed slightly: *.obj has been added
766 and CVS* has been changed to CVS CVS.adm.
768 * CVS now supports password authentication when accessing remote
769 repositories; this is useful for sites that can't use rsh (because of
770 a firewall, for example), and also don't have kerberos. See node
771 "Password authenticated" (in "Remote repositories", in
772 doc/cvs.texinfo) for more details. Note: This feature requires both
773 the client and server to be upgraded.
775 * Using the -kb option to specify binary files now works--most cases
776 did not work before. See the "Binary files" section of
777 doc/cvs.texinfo for details.
779 * New developer communication features. See the "Watches" section of
780 doc/cvs.texinfo for details.
782 * RCS keyword "Name" supported for "cvs update -r <tag>" and "cvs
785 * If there is a group whose name matches a compiled in value which
786 defaults to "cvsadmin", only members of that group can use "cvs
787 admin". This replaces the CVS_NOADMIN option.
789 * CVS now sets the modes of files in the repository based on the
790 CVSUMASK environment variable or a compiled in value defaulting to
791 002. This way other developers will be able to access the files in
792 the repository regardless of the umask of the developer creating them.
794 * The command names in .cvsrc now match the official name of the
795 command, not the one (possibly an alias) by which it was invoked. If
796 you had previously relied on "cvs di" and "cvs diff" using different
797 options, instead use a shell function or alias (for example "alias
798 cvsdi='cvs diff -u'"). You also can specify global CVS options (like
799 "-z") using the command name "cvs".
801 Changes from 1.5 to 1.6:
803 * Del updated the man page to include all of the new features
806 * "cvs tag" now supports a "-r | -D" option for tagging an already
807 tagged revision / specific revision of a file.
809 * There is a "taginfo" file in CVSROOT that supports filtering and
810 recording of tag operations.
812 * Long options support added, including --help and --version options.
814 * "cvs release" no longer cares whether or not the directory being
815 released has an entry in the `modules' file.
817 * The modules file now takes a -e option which is used instead of -o
818 for "cvs export". If your modules file has a -o option which you want
819 to be used for "cvs export", change it to specify -e as well as -o.
821 * "cvs export" now takes a -k option to set RCS keyword expansion.
822 This way you can export binary files. If you want the old behavior,
823 you need to specify -kv.
825 * "cvs update", "cvs rdiff", "cvs checkout", "cvs import", "cvs
826 release", "cvs rtag", and "cvs tag" used to take -q and -Q options
827 after the command name (e.g. "cvs update -q"). This was confusing
828 because other commands, such as "cvs ci", did not. So the options
829 after the command name have been removed and you must now specify, for
830 example, "cvs -q update", which has been supported since CVS 1.3.
832 * New "wrappers" feature. This allows you to set a hook which
833 transforms files on their way in and out of cvs (apparently on the
834 NeXT there is some particular usefulness in tarring things up in the
835 repository). It also allows you to declare files as merge-by-copy
836 which means that instead of trying to merge the file, CVS will merely
837 copy the new version. There is a CVSROOT/cvswrappers file and an
838 optionsl ~/.cvswrappers file to support this feature.
840 * You can set CVSROOT to user@host:dir, not just host:dir, if your
841 username on the server host is different than on the client host.
843 * VISUAL is accepted as well as EDITOR.
845 * $CVSROOT is expanded in *info files.
847 Changes from 1.4A2 to 1.5:
849 * Remote implementation. This is very helpful when collaborating on a
850 project with someone across a wide-area network. This release can
851 also be used locally, like other CVS versions, if you have no need for
854 Here are some of the features of the remote implementation:
855 - It uses reliable transport protocols (TCP/IP) for remote repository
856 access, not NFS. NFS is unusable over long distances (and sometimes
857 over short distances)
858 - It transfers only those files that have changed in the repository or
859 the working directory. To save transmission time, it will transfer
860 patches when appropriate, and can compress data for transmission.
861 - The server never holds CVS locks while waiting for a reply from the client;
862 this makes the system robust when used over flaky networks.
864 The remote features are documented in doc/cvsclient.texi in the CVS
865 distribution, but the main doc file, cvs.texinfo, has not yet been
866 updated to include the remote features.
868 * Death support. See src/README-rm-add for more information on this.
870 * Many speedups, especially from jtc@cygnus.com.
872 * CVS 1.2 compatibility code has been removed as a speedup. If you
873 have working directories checked out by CVS 1.2, CVS 1.3 or 1.4A2 will
874 try to convert them, but CVS 1.5 and later will not (if the working
875 directory is up to date and contains no extraneous files, you can just
876 remove it, and then check out a new working directory). Likewise if
877 your repository contains a CVSROOT.adm directory instead of a CVSROOT
878 directory, you need to rename it.
880 Fri Oct 21 20:58:54 1994 Brian Berliner <berliner@sun.com>
882 * Changes between CVS 1.3 and CVS 1.4 Alpha-2
884 * A new program, "cvsbug", is provided to let you send bug reports
885 directly to the CVS maintainers. Please use it instead of sending
886 mail to the info-cvs mailing list. If your build fails, you may
887 have to invoke "cvsbug" directly from the "src" directory as
890 * A new User's Guide and Tutorial, written by Per Cederqvist
891 <ceder@signum.se> of Signum Support. See the "doc" directory. A
892 PostScript version is included as "doc/cvs.ps".
894 * The Frequesntly Asked Questions file, FAQ, has been added to the
895 release. Unfortunately, its contents are likely out-of-date.
897 * The "cvsinit" shell script is now installed in the $prefix/bin
898 directory like the other programs. You can now create new
899 CVS repositories with great ease.
901 * Index: lines are now printed on output from 'diff' and 'rdiff',
902 in order to facilitate application of patches to multiple subdirs.
904 * Support for a ~/.cvsrc file, which allows you to specify options
905 that are always supposed to be given to a specific command. This
906 feature shows the non-orthogonality of the option set, since while
907 there may be an option to turn something on, the option to turn
908 that same thing off may not exist.
910 * You can now list subdirectories that you wish to ignore in a
911 modules listing, such as:
913 gcc -a gnu/gcc, !gnu/gcc/testsuites
915 which will check out everything underneath gnu/gcc, except
916 everything underneath gnu/gcc/testsuites.
918 * It is now much harder to accidentally overwrite an existing tag
919 name, since attempting to move a tag name will result in a error,
920 unless the -F (force) flag is given to the tag subcommands.
922 * Better error checking on matching of the repository used to
923 check code out from against the repository the current cvs
924 commnands would use. (Thanks to Mark Baushke <mdb@cisco.com>)
926 * Better support for sites with multiple CVSROOT repositories has
927 been contributed. The file "CVS/Root" in your working directory
928 is created to hold the full path to the CVS repository and a
929 simple check is made against your current CVSROOT setting.
931 * You can now specify an RCS keyword substitution value when you
932 import files into the repository.
934 * Uses a much newer version of Autoconf, and conforms to the GNU
935 coding standards much more closely. No, it still doesn't have
938 * Code cleanup. Many passes through gcc -Wall helped to identify
939 a number of questionable constructs. Most arbitrary length limits
942 * Profiling to determine bottlenecks helped to identify the best
943 places to spend time speeding up the code, which was then done. A
944 number of performance enhancements in filename matching have sped
947 * Many more contributions have been added to the "contrib"
948 directory. See the README file in that directory for more
951 * "cvs commit" will try harder to not change the file's
952 modification time after the commit. If the file does not change
953 as a result of the commit operation, CVS will preserve the
954 original modification time, thus speeding up future make-type
957 * "cvs commit" now includes any removed files in the (optional)
958 pre-commit checking program that may be invoked. Previously, only
959 added and modified files were included.
961 * It is now possible to commit a file directly onto the trunk at a
962 specific revision level by doing "cvs commit -r3.0 file.c", where
963 "3.0" specifies the revision you wish to create. The file must be
964 up-to-date with the current head of the trunk for this to succeed.
966 * "cvs commit" will now function with a pre-commit program that
967 has arguments specified in the "commitinfo" file.
969 * The "mkmodules" program will now look within the
970 $CVSROOT/CVSROOT/checkoutlist" file for any additional files that
971 should be automatically checked out within CVSROOT; mkmodules also
972 tries harder to preserve any execute bits the files may have
975 * "cvs diff" is much more accurate about its exit status now. It
976 now returns the maximum exit status of any invoked diff.
978 * The "-I !" option is now supported for the import and update
979 commands correctly. It will properly clear the ignore list now.
981 * Some problems with "cvs import" handling of .cvsignore have been
982 fixed; as well, some rampant recursion problems with import have
985 * "cvs rdiff" (aka "cvs patch") now tries to set the modify time
986 of any temporary files it uses to match those specified for the
987 particular revision. This allows a more accurate patch image to
990 * "cvs status" has improved revision descriptions. "Working
991 revision" is used for the revision of the working file that you
992 edit directly; "Repository revision" is the revision of the file
993 with the $CVSROOT source repository. Also, the output is clearer
994 with regard to sticky and branch revisions.
996 * CVS no longer dumps core when given a mixture of directories and
997 files in sub-directories (as in "cvs ci file1 dir1/file2").
998 Instead, arguments are now clumped into their respective directory
999 and operated on in chunks, together.
1001 * If the CVSEDITOR environment variable is set, that editor is
1002 used for log messages instead of the EDITOR environment variable.
1003 This makes it easy to substitute intelligent programs to make more
1004 elaborate log messages. Contributed by Mark D Baushke
1007 * Command argument changes:
1008 cvs: The "-f" option has been added to ignore
1010 commit: Renamed the "-f logfile" option to the
1011 "-F logfile" option. Added the "-f"
1012 option to force a commit of the specified
1013 files (this disables recursion).
1014 history: Added "-t timezone" option to force any
1015 date-specific output into the specified
1017 import: Added "-d" option to use the file's
1018 modification time as the time of the
1019 import. Added "-k sub" option to set the
1020 default RCS keyword substitution mode for
1021 newly-created files.
1022 remove: Added "-f" option to force the file's
1023 automatic removal if it still exists in
1024 the working directory (use with caution).
1025 rtag: Added "-F" option to move the tag if it
1026 already exists -- new default is to NOT
1027 move tags automatically.
1028 tag: Added "-F" option to move the tag if it
1029 already exists -- new default is to NOT
1030 move tags automatically.
1032 Tue Apr 7 15:55:25 1992 Brian Berliner (berliner at sun.com)
1034 * Changes between CVS 1.3 Beta-3 and official CVS 1.3!
1036 * A new shell script is provided, "./cvsinit", which can be run at
1037 install time to help setup your $CVSROOT area. This can greatly
1038 ease your entry into CVS usage.
1040 * The INSTALL file has been updated to include the machines on
1041 which CVS has compiled successfully. I think CVS 1.3 is finally
1042 portable. Thanks to all the Beta testers!
1044 * Support for the "editinfo" file was contributed. This file
1045 (located in $CVSROOT/CVSROOT) can be used to specify a special
1046 "editor" to run on a per-directory basis within the repository,
1047 instead of the usual user's editor. As such, it can verify that
1048 the log message entered by the user is of the appropriate form
1049 (contains a bugid and test validation, for example).
1051 * The manual pages cvs(1) and cvs(5) have been updated.
1053 * The "mkmodules" command now informs you when your modules file
1054 has duplicate entries.
1056 * The "add" command now preserves any per-directory sticky tag when
1057 you add a new directory to your checked-out sources.
1059 * The "admin" command is now a fully recursive interface to the
1060 "rcs" program which operates on your checked-out sources. It no
1061 longer requires you to specify the full path to the RCS file.
1063 * The per-file sticky tags can now be effectively removed with
1064 "cvs update -A file", even if you had checked out the whole
1065 directory with a per-directory sticky tag. This allows a great
1066 deal of flexibility in managing the revisions that your checked-out
1067 sources are based upon (both per-directory and per-file sticky
1070 * The "cvs -n commit" command now works, to show which files are
1071 out-of-date and will cause the real commit to fail, or which files
1072 will fail any pre-commit checks. Also, the "cvs -n import ..."
1073 command will now show you what it would've done without actually
1076 * Doing "cvs commit modules" to checkin the modules file will no
1077 properly run the "mkmodules" program (assuming you have setup your
1078 $CVSROOT/CVSROOT/modules file to do so).
1080 * The -t option in the modules file (which specifies a program to
1081 run when you do a "cvs rtag" operation on a module) now gets the
1082 symbolic tag as the second argument when invoked.
1084 * When the source repository is locked by another user, that user's
1085 login name will be displayed as the holder of the lock.
1087 * Doing "cvs checkout module/file.c" now works even if
1088 module/file.c is in the Attic (has been removed from main-line
1091 * Doing "cvs commit */Makefile" now works as one would expect.
1092 Rather than trying to commit everything recursively, it will now
1093 commit just the files specified.
1095 * The "cvs remove" command is now fully recursive. To schedule a
1096 file for removal, all you have to do is "rm file" and "cvs rm".
1097 With no arguments, "cvs rm" will schedule all files that have been
1098 physically removed for removal from the source repository at the
1101 * The "cvs tag" command now prints "T file" for each file that was
1102 tagged by this invocation and "D file" for each file that had the
1103 tag removed (as with "cvs tag -d").
1105 * The -a option has been added to "cvs rtag" to force it to clean
1106 up any old, matching tags for files that have been removed (in the
1107 Attic) that may not have been touched by this tag operation. This
1108 can help keep a consistent view with your tag, even if you re-use
1111 Sat Feb 29 16:02:05 1992 Brian Berliner (berliner at sun.com)
1113 * Changes between CVS 1.3 Beta-2 and CVS 1.3 Beta-3
1115 * Many portability fixes, thanks to all the Beta testers! With any
1116 luck, this Beta release will compile correctly on most anything.
1117 Hey, what are we without our dreams.
1119 * CVS finally has support for doing isolated development on a
1120 branch off the current (or previous!) revisions. This is also
1121 extremely nice for generating patches for previously released
1122 software while development is progressing on the next release.
1123 Here's an example of creating a branch to fix a patch with the 2.0
1124 version of the "foo" module, even though we are already well into
1125 the 3.0 release. Do:
1127 % cvs rtag -b -rFOO_2_0 FOO_2_0_Patch foo
1128 % cvs checkout -rFOO_2_0_Patch foo
1133 A physical branch will be created in the RCS file only when you
1134 actually commit the change. As such, forking development at some
1135 random point in time is extremely light-weight -- requiring just a
1136 symbolic tag in each file until a commit is done. To fork
1137 development at the currently checked out sources, do:
1139 % cvs tag -b Personal_Hack
1140 % cvs update -rPersonal_Hack
1144 Now, if you decide you want the changes made in the Personal_Hack
1145 branch to be merged in with other changes made in the main-line
1146 development, you could do:
1148 % cvs commit # to make Personal_Hack complete
1149 % cvs update -A # to update sources to main-line
1150 % cvs update -jPersonal_Hack # to merge Personal_Hack
1152 to update your checked-out sources, or:
1154 % cvs checkout -jPersonal_Hack module
1156 to checkout a fresh copy.
1158 To support this notion of forked development, CVS reserves
1159 all even-numbered branches for its own use. In addition, CVS
1160 reserves the ".0" and ".1" branches. So, if you intend to do your
1161 own branches by hand with RCS, you should use odd-numbered branches
1162 starting with ".3", as in "1.1.3", "1.1.5", 1.2.9", ....
1164 * The "cvs commit" command now supports a fully functional -r
1165 option, allowing you to commit your changes to a specific numeric
1166 revision or symbolic tag with full consistency checks. Numeric
1167 tags are useful for bringing your sources all up to some revision
1172 For symbolic tags, you can only commit to a tag that references a
1173 branch in the RCS file. One created by "cvs rtag -b" or from
1174 "cvs tag -b" is appropriate (see below).
1176 * Roland Pesch <pesch@cygnus.com> and K. Richard Pixley
1177 <rich@cygnus.com> were kind enough to contribute two new manual
1178 pages for CVS: cvs(1) and cvs(5). Most of the new CVS 1.3 features
1179 are now documented, with the exception of the new branch support
1180 added to commit/rtag/tag/checkout/update.
1182 * The -j options of checkout/update have been added. The "cvs join"
1183 command has been removed.
1185 With one -j option, CVS will merge the changes made between the
1186 resulting revision and the revision that it is based on (e.g., if
1187 the tag refers to a branch, CVS will merge all changes made in
1188 that branch into your working file).
1190 With two -j options, CVS will merge in the changes between the two
1191 respective revisions. This can be used to "remove" a certain delta
1192 from your working file. E.g., If the file foo.c is based on
1193 revision 1.6 and I want to remove the changes made between 1.3 and
1196 % cvs update -j1.5 -j1.3 foo.c # note the order...
1198 In addition, each -j option can contain on optional date
1199 specification which, when used with branches, can limit the chosen
1200 revision to one within a specific date. An optional date is
1201 specified by adding a colon (:) to the tag, as in:
1203 -jSymbolic_Tag:Date_Specifier
1205 An example might be what "cvs import" tells you to do when you have
1206 just imported sources that have conflicts with local changes:
1208 % cvs checkout -jTAG:yesterday -jTAG module
1210 which tells CVS to merge in the changes made to the branch
1211 specified by TAG in the last 24 hours. If this is not what is
1212 intended, substitute "yesterday" for whatever format of date that
1213 is appropriate, like:
1215 % cvs checkout -jTAG:'1 week ago' -jTAG module
1217 * "cvs diff" now supports the special tags "BASE" and "HEAD". So,
1220 % cvs diff -u -rBASE -rHEAD
1222 will effectively show the changes made by others (in unidiff
1223 format) that will be merged into your working sources with your
1224 next "cvs update" command. "-rBASE" resolves to the revision that
1225 your working file is based on. "-rHEAD" resolves to the current
1226 head of the branch or trunk that you are working on.
1228 * The -P option of "cvs checkout" now means to Prune empty
1229 directories, as with "update". The default is to not remove empty
1230 directories. However, if you do "checkout" with any -r options, -P
1231 will be implied. I.e., checking out with a tag will cause empty
1232 directories to be pruned automatically.
1234 * The new file INSTALL describes how to install CVS, including
1235 detailed descriptions of interfaces to "configure".
1237 * The example loginfo file in examples/loginfo has been updated to
1238 use the perl script included in contrib/log.pl. The nice thing
1239 about this log program is that it records the revision numbers of
1240 your change in the log message.
1242 Example files for commitinfo and rcsinfo are now included in the
1245 * All "#if defined(__STDC__) && __STDC__ == 1" lines have been
1246 changed to be "#if __STDC__" to fix some problems with the former.
1248 * The lib/regex.[ch] files have been updated to the 1.3 release of
1249 the GNU regex package.
1251 * The ndbm emulation routines included with CVS 1.3 Beta-2 in the
1252 src/ndbm.[ch] files has been moved into the src/myndbm.[ch] files
1253 to avoid any conflict with the system <ndbm.h> header file. If
1254 you had a previous CVS 1.3 Beta release, you will want to "cvs
1255 remove ndbm.[ch]" form your copy of CVS as well.
1257 * "cvs add" and "cvs remove" are a bit more verbose, telling you
1258 what to do to add/remove your file permanently.
1260 * We no longer mess with /dev/tty in "commit" and "add".
1262 * More things are quiet with the -Q option set.
1264 * New src/config.h option: If CVS_BADROOT is set, CVS will not
1265 allow people really logged in as "root" to commit changes.
1267 * "cvs diff" exits with a status of 0 if there were no diffs, 1 if
1268 there were diffs, and 2 if there were errors.
1270 * "cvs -n diff" is now supported so that you can still run diffs
1271 even while in the middle of committing files.
1273 * Handling of the CVS/Entries file is now much more robust.
1275 * The default file ignore list now includes "*.so".
1277 * "cvs import" did not expand '@' in the log message correctly. It
1278 does now. Also, import now uses the ignore file facility
1281 Import will now tell you whether there were conflicts that need to
1282 be resolved, and how to resolve them.
1284 * "cvs log" has been changed so that you can "log" things that are
1285 not a part of the current release (in the Attic).
1287 * If you don't change the editor message on commit, CVS now prompts
1288 you with the choice:
1290 !)reuse this message unchanged for remaining dirs
1292 which allows you to tell CVS that you have no intention of changing
1293 the log message for the remainder of the commit.
1295 * It is no longer necessary to have CVSROOT set if you are using
1296 the -H option to get Usage information on the commands.
1298 * Command argument changes:
1299 checkout: -P handling changed as described above.
1300 New -j option (up to 2 can be specified)
1301 for doing rcsmerge kind of things on
1303 commit: -r option now supports committing to a
1304 numeric or symbolic tags, with some
1305 restrictions. Full consistency checks will
1307 Added "-f logfile" option, which tells
1308 commit to glean the log message from the
1309 specified file, rather than invoking the
1311 rtag: Added -b option to create a branch tag,
1312 useful for creating a patch for a previous
1313 release, or for forking development.
1314 tag: Added -b option to create a branch tag,
1315 useful for creating a patch for a previous
1316 release, or for forking development.
1317 update: New -j option (up to 2 can be specified)
1318 for doing rcsmerge kind of things on
1321 Thu Jan 9 10:51:35 MST 1992 Jeff Polk (polk at BSDI.COM)
1323 * Changes between CVS 1.3 Beta-1 and CVS 1.3 Beta-2
1325 * Thanks to K. Richard Pixley at Cygnus we now have function
1326 prototypes in all the files
1328 * Some small changes to configure for portability. There have
1329 been other portability problems submitted that have not been fixed
1330 (Brian will be working on those). Additionally all __STDC__
1331 tests have been modified to check __STDC__ against the constant 1
1332 (this is what the Second edition of K&R says must be true).
1334 * Lots of additional error checking for forked processes (run_exec)
1335 (thanks again to K. Richard Pixley)
1337 * Lots of miscellaneous bug fixes - including but certainly not
1339 various commit core dumps
1340 various update core dumps
1341 bogus results from status with numeric sticky tags
1342 commitprog used freed memory
1343 Entries file corruption caused by No_Difference
1344 commit to revision broken (now works if branch exists)
1345 ignore file processing broken for * and !
1346 ignore processing didn't handle memory reasonably
1347 miscellaneous bugs in the recursion processor
1348 file descriptor leak in ParseInfo
1349 CVSROOT.adm->CVSROOT rename bug
1352 * Reformatted all the code in src (with GNU indent) and then
1353 went back and fixed prototypes, etc since indent gets confused. The
1354 rationale is that it is better to do it sooner than later and now
1355 everything is consistent and will hopefully stay that way.
1356 The basic options to indent were: "-bad -bbb -bap -cdb -d0 -bl -bli0
1357 -nce -pcs -cs -cli4 -di1 -nbc -psl -lp -i4 -ip4 -c41" and then
1358 miscellaneous formatting fixes were applied. Note also that the
1359 "-nfc1" or "-nfca" may be appropriate in files where comments have
1360 been carefully formatted (e.g, modules.c).
1362 Sat Dec 14 20:35:22 1991 Brian Berliner (berliner at sun.com)
1364 * Changes between CVS 1.2 and CVS 1.3 Beta are described here.
1366 * Lots of portability work. CVS now uses the GNU "configure"
1367 script to dynamically determine the features provided by your
1368 system. It probably is not foolproof, but it is better than
1369 nothing. Please let me know of any portability problems. Some
1370 file names were changed to fit within 14-characters.
1372 * CVS has a new RCS parser that is much more flexible and
1373 extensible. It should read all known RCS ",v" format files.
1375 * Most of the commands now are fully recursive, rather than just
1376 operating on the current directory alone. This includes "commit",
1377 which makes it real easy to do an "atomic" commit of all the
1378 changes made to a CVS hierarchy of sources. Most of the commands
1379 also correctly handle file names that are in directories other than
1380 ".", including absolute path names. Commands now accept the "-R"
1381 option to force recursion on (though it is always the default now)
1382 and the "-l" option to force recursion off, doing just "." and not
1383 any sub-directories.
1385 * CVS supports many of the features provided with the RCS 5.x
1386 distribution - including the new "-k" keyword expansion options. I
1387 recommend using RCS 5.x (5.6 is the current official RCS version)
1388 and GNU diff 1.15 (or later) distributions with CVS.
1390 * Checking out files with symbolic tags/dates is now "sticky", in
1391 that CVS remembers the tag/date used for each file (and directory)
1392 and will use that tag/date automatically on the next "update" call.
1393 This stickyness also holds for files checked out with the the new
1394 RCS 5.x "-k" options.
1396 * The "cvs diff" command now recognizes all of the rcsdiff 5.x
1397 options. Unidiff format is available by installing the GNU
1398 diff 1.15 distribution.
1400 * The old "CVS.adm" directories created on checkout are now called
1401 "CVS" directories, to look more like "RCS" and "SCCS". Old CVS.adm
1402 directories are automagically converted to CVS directories. The
1403 old "CVSROOT.adm" directory within the source repository is
1404 automagically changed into a "CVSROOT" directory as well.
1406 * Symbolic links in the source repository are fully supported ONLY
1407 if you use RCS 5.6 or later and (of course) your system supports
1410 * A history database has been contributed which maintains the
1411 history of certain CVS operations, as well as providing a wide array
1412 of querying options.
1414 * The "cvs" program has a "-n" option which can be used with the
1415 "update" command to show what would be updated without actually
1416 doing the update, like: "cvs -n update". All usage statements
1417 have been cleaned up and made more verbose.
1419 * The module database parsing has been rewritten. The new format
1420 is compatible with the old format, but with much more
1421 functionality. It allows modules to be created that grab pieces or
1422 whole directories from various different parts of your source
1423 repository. Module-relative specifications are also correctly
1424 recognized now, like "cvs checkout module/file.c".
1426 * A configurable template can be specified such that on a "commit",
1427 certain directories can supply a template that the user must fill
1428 before completing the commit operation.
1430 * A configurable pre-commit checking program can be specified which
1431 will run to verify that a "commit" can happen. This feature can be
1432 used to restrict certain users from changing certain pieces of the
1433 source repository, or denying commits to the entire source
1436 * The new "cvs export" command is much like "checkout", but
1437 establishes defaults suitable for exporting code to others (expands
1438 out keywords, forces the use of a symbolic tag, and does not create
1439 "CVS" directories within the checked out sources.
1441 * The new "cvs import" command replaces the deprecated "checkin"
1442 shell script and is used to import sources into CVS control. It is
1443 also much faster for the first-time import. Some algorithmic
1444 improvements have also been made to reduce the number of
1445 conflicting files on next-time imports.
1447 * The new "cvs admin" command is basically an interface to the
1448 "rcs" program. (Not yet implemented very well).
1450 * Signal handling (on systems with BSD or POSIX signals) is much
1451 improved. Interrupting CVS now works with a single interrupt!
1453 * CVS now invokes RCS commands by direct fork/exec rather than
1454 calling system(3). This improves performance by removing a call to
1455 the shell to parse the arguments.
1457 * Support for the .cvsignore file has been contributed. CVS will
1458 now show "unknown" files as "? filename" as the result of an "update"
1459 command. The .cvsignore file can be used to add files to the
1460 current list of ignored files so that they won't show up as unknown.
1462 * Command argument changes:
1463 cvs: Added -l to turn off history logging.
1464 Added -n to show what would be done without actually
1466 Added -q/-Q for quiet and really quiet settings.
1467 Added -t to show debugging trace.
1468 add: Added -k to allow RCS 5.x -k options to be specified.
1469 admin: New command; an interface to rcs(1).
1470 checkout: Added -A to reset sticky tags/date/options.
1471 Added -N to not shorten module paths.
1472 Added -R option to force recursion.
1473 Changed -p (prune empty directories) to -P option.
1474 Changed -f option; forcing tags match is now default.
1475 Added -p option to checkout module to standard output.
1476 Added -s option to cat the modules db with status.
1477 Added -d option to checkout in the specified directory.
1478 Added -k option to use RCS 5.x -k support.
1479 commit: Removed -a option; use -l instead.
1481 Added -l option to disable recursion.
1482 Added -R option to force recursion.
1483 If no files specified, commit is recursive.
1484 diff: Now recognizes all RCS 5.x rcsdiff options.
1485 Added -l option to disable recursion.
1486 Added -R option to force recursion.
1487 history: New command; displays info about CVS usage.
1488 import: Replaces "checkin" shell script; imports sources
1489 under CVS control. Ignores files on the ignore
1490 list (see -I option or .cvsignore description above).
1491 export: New command; like "checkout", but w/special options
1492 turned on by default to facilitate exporting sources.
1493 join: Added -B option to join from base of the branch;
1494 join now defaults to only joining with the top two
1495 revisions on the branch.
1496 Added -k option for RCS 5.x -k support.
1497 log: Supports all RCS 5.x options.
1498 Added -l option to disable recursion.
1499 Added -R option to force recursion.
1500 patch: Changed -f option; forcing tags match is now default.
1501 Added -c option to force context-style diffs.
1502 Added -u option to support unidiff-style diffs.
1503 Added -V option to support RCS specific-version
1504 keyword expansion formats.
1505 Added -R option to force recursion.
1506 remove: No option changes. It's a bit more verbose.
1507 rtag: Equivalent to the old "cvs tag" command.
1508 No option changes. It's a lot faster for re-tag.
1509 status: New output formats with more information.
1510 Added -l option to disable recursion.
1511 Added -R option to force recursion.
1512 Added -v option to show symbolic tags for files.
1513 tag: Functionality changed to tag checked out files
1514 rather than modules; use "rtag" command to get the
1515 old "cvs tag" behaviour.
1516 update: Added -A to reset sticky tags/date/options.
1517 Changed -p (prune empty directories) to -P option.
1518 Changed -f option; forcing tags match is now default.
1519 Added -p option to checkout module to standard output.
1520 Added -I option to add files to the ignore list.
1521 Added -R option to force recursion.
1525 * Jeff Polk <polk@bsdi.com> rewrote most of the grody code of CVS
1526 1.2. He made just about everything dynamic (by using malloc),
1527 added a generic hashed list manager, re-wrote the modules database
1528 parsing in a compatible - but extended way, generalized directory
1529 hierarchy recursion for virtually all the commands (including
1530 commit!), generalized the loginfo file to be used for pre-commit
1531 checks and commit templates, wrote a new and flexible RCS parser,
1532 fixed an uncountable number of bugs, and helped in the design of
1533 future CVS features. If there's anything gross left in CVS, it's
1536 * David G. Grubbs <dgg@odi.com> contributed the CVS "history" and
1537 "release" commands. As well as the ever-so-useful "-n" option of
1538 CVS which tells CVS to show what it would do, without actually
1539 doing it. He also contributed support for the .cvsignore file.
1541 * Paul Sander, HaL Computer Systems, Inc. <paul@hal.com> wrote and
1542 contributed the code in lib/sighandle.c. I added support for
1543 POSIX, BSD, and non-POSIX/non-BSD systems.
1545 * Free Software Foundation contributed the "configure" script and
1546 other compatibility support in the "lib" directory, which will help
1547 make CVS much more portable.
1549 * Many others have contributed bug reports and enhancement requests.
1550 Some have even submitted actual code which I have not had time yet
1551 to integrate into CVS. Maybe for the next release.
1553 * Thanks to you all!
1555 Wed Feb 6 10:10:58 1991 Brian Berliner (berliner at sun.com)
1557 * Changes from CVS 1.0 Patchlevel 1 to CVS 1.0 Patchlevel 2; also
1558 known as "Changes from CVS 1.1 to CVS 1.2".
1560 * Major new support with this release is the ability to use the
1561 recently-posted RCS 5.5 distribution with CVS 1.2. See below for
1562 other assorted bug-fixes that have been thrown in.
1564 * ChangeLog (new): Added Emacs-style change-log file to CVS 1.2
1565 release. Chronological description of changes between release.
1567 * README: Small fixes to installation instructions. My email
1568 address is now "berliner@sun.com".
1570 * src/Makefile: Removed "rcstime.h". Removed "depend" rule.
1572 * src/partime.c: Updated to RCS 5.5 version with hooks for CVS.
1573 * src/maketime.c: Updated to RCS 5.5 version with hooks for CVS.
1574 * src/rcstime.h: Removed from the CVS 1.2 distribution.
1575 Thanks to Paul Eggert <eggert@twinsun.com> for these changes.
1577 * src/checkin.csh: Support for RCS 5.5 parsing.
1578 Thanks to Paul Eggert <eggert@twinsun.com> for this change.
1580 * src/collect_sets.c (Collect_Sets): Be quieter if "-f" option is
1581 specified. When checking out files on-top-of other files that CVS
1582 doesn't know about, run a diff in the hopes that they are really
1583 the same file before aborting.
1585 * src/commit.c (branch_number): Fix for RCS 5.5 parsing.
1586 Thanks to Paul Eggert <eggert@twinsun.com> for this change.
1588 * src/commit.c (do_editor): Bug fix - fprintf missing argument
1589 which sometimes caused core dumps.
1591 * src/modules.c (process_module): Properly NULL-terminate
1592 update_dir[] in all cases.
1594 * src/no_difference.c (No_Difference): The wrong RCS revision was
1595 being registered in certain (strange) cases.
1597 * src/patch.c (get_rcsdate): New algorithm. No need to call
1598 maketime() any longer.
1599 Thanks to Paul Eggert <eggert@twinsun.com> for this change.
1601 * src/patchlevel.h: Increased patch level to "2".
1603 * src/subr.c (isdir, islink): Changed to compare stat mode bits
1606 * src/tag.c (tag_file): Added support for following symbolic links
1607 that are in the master source repository when tagging. Made tag
1608 somewhat quieter in certain cases.
1610 * src/update.c (update_process_lists): Unlink the user's file if it
1611 was put on the Wlist, meaning that the user's file is not modified
1612 and its RCS file has been removed by someone else.
1614 * src/update.c (update): Support for "cvs update dir" to correctly
1615 just update the argument directory "dir".
1617 * src/cvs.h: Fixes for RCS 5.5 parsing.
1618 * src/version_number.c (Version_Number): Fixes for parsing RCS 5.5
1619 and older RCS-format files.
1620 Thanks to Paul Eggert <eggert@twinsun.com> for these changes.
1622 * src/version_number.c (Version_Number): Bug fixes for "-f" option.
1623 Bug fixes for parsing with certain branch numbers. RCS
1624 revision/symbol parsing is much more solid now.
1626 Wed Feb 14 10:01:33 1990 Brian Berliner (berliner at sun.com)
1628 * Changes from CVS 1.0 Patchlevel 0 to CVS 1.0 Patchlevel 1; also
1629 known as "Changes from CVS 1.0 to CVS 1.1".
1631 * src/patch.c (get_rcsdate): Portability fix. Replaced call to
1632 timelocal() with call to maketime().
1634 Mon Nov 19 23:15:11 1990 Brian Berliner (berliner at prisma.com)
1636 * Sent CVS 1.0 release to comp.sources.unix moderator and FSF.
1638 * Special thanks to Dick Grune <dick@cs.vu.nl> for his work on the
1639 1986 version of CVS and making it available to the world. Dick's
1640 version is available on uunet.uu.net in the
1641 comp.sources.unix/volume6/cvs directory.
