1 Changes since 1.12.12: 2 ********************** 3 4 SECURITY FIXES 5 6 * CVS now uses version 1.2.3 of the ZLib compression libraries in order to 7 avoid two recently announced security vulnerabilities in them. Both may be 8 used for denial of service attacks and one may reportedly allow execution of 9 arbitrary code, though this is not confirmed. Please see the CERT 10 vulnerabilities advisories #238678 <http://www.kb.cert.org/vuls/id/238678> & 11 #680620 <http://www.kb.cert.org/vuls/id/680620> for more. 12 13 NEW FEATURES 14 15 * Thanks to Conrad Pino <conrad (a] pino.com>, a hang in the Windows client, which 16 had pretty much rendered the client useless, has been fixed. 17 18 * A minor problem preventing build of the Kerberos4 client has been fixed. 19 20 * The path to the config file may be set as an argument to the CVS server 21 commands. 22 23 * Sections of directives specific to one or more repositories and not others 24 may now be specified in the config file. 25 26 * %{sV} format strings are now available to the verifymsg trigger, similar to 27 the %{stVv} available to loginfo. 28 29 * `cvs watch add' on an empty directory no longer clears watchers, and 30 specifying a directory for `cvs watch add' now (correctly) sets default 31 attributes. 32 33 * Missing CVSROOT/history files will now cause CVS to attempt to create one. 34 To suppress history logging, set LogHistory equal to the empty string in 35 CVSROOT/config. 36 37 * There are several new options available in CVSROOT/config. These are 38 TmpDir, HistoryLogPath, HistorySearchPath, MinCompressionLevel, & 39 MaxCompressionLevel. Please see the manual for more. 40 41 * CVS on Solaris 10 was refusing to parse command options. This has been 42 fixed. 43 44 * The Windows client now creates locks compatible with older versions of CVS by 45 default. This should only be relevant if your client is accessing a local 46 repository concurrently with another, older client. If you would like to 47 disable compatibility mode (because it is slightly faster), edit the 48 LOCK_COMPATIBILITY flag in windows-NT/config.h and recompile. 49 50 * Misc efficiency and portability improvements. 51 52 BUG FIXES 53 54 * Thanks to Serguei E. Leontiev <lse (a] CryptoPro.ru>, CVS with Kerberos 5 GSSAPI 55 should automatically link on FreeBSD 5.x. (bug #14639). 56 57 * Thanks to Rahul Bhargava <rahul (a] wandisco.com>, heavily loaded systems 58 suffering from a disk crash or power failure will not lose data they claimed 59 to have committed. 60 61 * CVS server now handles conflict markers in Entry requests as documented. 62 63 * CVS now remembers that binary file merge conflicts occurred until the 64 timestamp of the updated binary file changes. 65 66 * CVS client now saves some bandwidth by not sending the contents of files 67 with conflicts to the server when it isn't needed. 68 69 * CVS now does correct locking during import. 70 71 * A problem where the server could block indefinitely waiting for an EOF from 72 the client when compression was enabled has been fixed. 73 74 * `cvs diff' no longer splits its arguments on spaces. 75 76 * Thanks to an old report and patch from Stewart Brodie <stewart (a] eh.org>, a 77 potential crash in response to a corrupt RCS file has been fixed. 78 79 * CVS now locks the history and val-tags files before writing to them. 80 Especially with large repositories, users should no longer see new warnings 81 about corrupt history records when using the `cvs history' command. Existing 82 corrupt history records will still need to be removed manually. val-tags 83 corruption should have had less obvious effects, but removing the 84 CVSROOT/val-tags file and allowing a 1.11.21 or later version of CVS to 85 regenerate it may eliminate a few odd behaviors and possibly cause a slight 86 speed up of read transactions in large repositories over time. 87 88 BUILD ISSUES 89 90 * The RPM spec file works again with the most modern versions of `rpm'. It 91 also finds the correct version of install-sh when building the CVS with 92 GSSAPI. 93 94 DEVELOPER ISSUES 95 96 * We've standardized on Automake 1.9.6 to get some at new features that make 97 our jobs easier. See the HACKING file for more on using the autotools with 98 CVS. 99 100 Changes from 1.12.11 to 1.12.12: 101 ******************************** 102 103 SERVER SECURITY FIXES 104 105 * Thanks to a report from Alen Zukich <alen.zukich (a] klocwork.com>, several minor 106 security issues have been addressed. One was a buffer overflow that is 107 potentially serious but which may not be exploitable, assigned CAN-2005-0753 108 by the Common Vulnerabilities and Exposures Project 109 <http://www.cve.mitre.org>. Other fixes resulting from Alen's report include 110 repair of an arbitrary free with no known exploit and several plugged memory 111 leaks and potentially freed NULL pointers which may have been exploitable for 112 a denial of service attack. 113 114 * Thanks to a report from Craig Monson <craig (a] malachiarts.com>, minor 115 potential vulnerabilities in the contributed Perl scripts have been fixed. 116 The confirmed vulnerability could allow the execution of arbitrary code on 117 the CVS server, but only if a user already had commit access and if one of 118 the contrib scripts was installed improperly, a condition which should have 119 been quickly visible to any administrator. The complete description of the 120 problem is here: <https://ccvs.cvshome.org/issues/show_bug.cgi?id=224>. If 121 you were making use of any of the contributed trigger scripts on a CVS 122 server, you should probably still replace them with the new versions, to be 123 on the safe side. 124 125 Unfortunately, our fix is incomplete. Taint-checking has been enabled in all 126 the contributed Perl scripts intended to be run as trigger scripts, but no 127 attempt has been made to ensure that they still run in taint mode. You will 128 most likely have to tweak the scripts in some way to make them run. Please 129 send any patches you find necessary back to <bug-cvs (a] nongnu.org> so that we 130 may again ship fully enabled scripts in the future. 131 132 You should also make sure that any home-grown Perl scripts that you might 133 have installed as CVS triggers also have taint-checking enabled. This can be 134 done by adding `-T' on the scripts' #! lines. Please try running 135 `perldoc perlsec' if you would like more information on general Perl security 136 and taint-checking. 137 138 NEW FEATURES 139 140 * Thanks to a report from Ian Abbott <abbotti (a] mev.co.uk>, a problem that caused 141 CVS to stop with broken assertions in certain time zones when daylight 142 savings is in effect has been fixed. 143 144 * A problem where a proxy server could fail to notice that its primary closed 145 the connection has been fixed. 146 147 * Failures to open the CVS_CLIENT_LOG, CVS_SERVER_LOG, and CVS_SECONDARY_LOG 148 are no longer fatal. 149 150 * CVS's client and server IO buffers now rely on a GNULIB modules for memory 151 management rather than taking on the task themseleves. This should be faster 152 on any system but may increase memory usage noticably on systems without the 153 POSIX mmap() function. Benchmark reports to <bug-cvs (a] gnulib.org> would be 154 welcome. 155 156 * Some more GNULIB functions have been imported and/or updated for portability 157 reasons. This change should not be visible to most users, though CVS may now 158 compile on a few more platforms. 159 160 * CVS creates a unique session id that gets written to the RCS files during 161 import and commit. When committing several files at once, they all get the 162 same 'commitid'. The commitid becomes visible with log and status commands, 163 and is derived and compatible with the cvsnt project. 164 165 * CVS once again compiles correctly configured with various combinations of 166 --disable-client, --disable-server, and --disable-proxy. 167 168 * CVS now accepts the <tag>:<date> format, which has long been acceptable as an 169 argument to -j options, in most places where <tag> used to be acceptable. An 170 empty tag in this format (e.g. ":<date>"), which used to be rejected, is now 171 interpreted as specifying a date on the trunk. 172 173 * CVS now uses ZLib 1.2.2. This fixes the minor vulnerability described here: 174 <http://www.kb.cert.org/vuls/id/238678>, as well as some other minor bugs we 175 are not aware of bug reports for in conjunction with CVS. 176 177 * `cvs -n release' now does what it should (see changes to the info-cleanup-0 178 test in sanity.sh for more). 179 180 * The configure script now prefers `ssh' to `rsh' when determining a default 181 executable to use when connecting via the :ext: method. 182 183 * A problem in the compression buffer that was causing some incompatibility 184 with some 3rd party CVS clients when compression was enabled has been fixed. 185 186 * Some files missing from the distribution have been added or readded. The 187 missing files were mostly development support files, with a few docs and 188 .cvsignore files thrown in. 189 190 * The incomplete Brazillian Portugese translation of the CVS manual is now 191 included in the distribution. 192 193 BUG FIXES 194 195 * Misc bug and documentation fixes. 196 197 * CVS now detects write errors on standard output. Before, e.g., 198 `cvs update -p FILE > /dev/full' would fail to report the write error. 199 200 * Thanks to a report and a patch from Georg Scwharz <georg.scwarz (a] freenet.de> 201 CVS now builds without error on IRIX 5.3 202 203 DEVELOPER ISSUES 204 205 * We've standardized on Automake 1.9.5 to get some at new features that make 206 our jobs easier. See the HACKING file for more on using the autotools with 207 CVS. 208 209 Changes from 1.12.10 to 1.12.11: 210 ******************************** 211 212 NEW FEATURES 213 214 * Thanks to Conrad Pino <conrad (a] pino.com>, the Windows build works once again. 215 216 * CVSROOT methods and option names are now case insensitive 217 218 * CVSROOT methods :ext: and :fork: now support the CVS_SERVER option. 219 220 * CVSROOT method :ext: now supports the CVS_RSH and Redirect options. 221 222 * Date handling has been improved slightly. 223 224 * Miscellaneous bug fixes. 225 226 * Miscellaneous documentation fixes. 227 228 BUG FIXES 229 230 * An intermittant assertion failure in checkout has been fixed. 231 232 * Thanks to a report from Chris Bohn <cbohn (a] rrinc.com>, all the source files 233 needed to build on Windows are now included in the source distribution. 234 235 Changes from 1.12.9 to 1.12.10: 236 ******************************* 237 238 NEW FEATURES 239 240 * The date formats which CVS accepts are now documented more fully in the 241 manual. 242 243 * CVS commands which accept dates now understand some more time zones, 244 including those which are some hours plus some fraction of an hour off of 245 universal coordinated time. 246 247 * `cvs ls filename' no longer causes an assertion failure. 248 249 * The maximum length of the discovered comment leader used in a Log keyword 250 substitution is now limited to 20 characters by default. If a longer leader 251 is discovered, then the keyword is not expanded. This default behavior may 252 be altered using the new MaxCommentLeaderLength & UseArchiveCommentLeader 253 config options. 254 255 * Commit messages once again include the full relative path to the file being 256 committed. 257 258 * Thanks to funding from Juniper Networks <http://juniper.net>, "write proxy" 259 functionality has been added to the CVS server. Write proxy functionality 260 allows any of multiple, read-only "secondary" servers to relay write requests 261 from clients to a single primary CVS server, allowing for a massive 262 redistribution of server load which is transparent to all known CVS clients. 263 264 * Thanks to funding from Juniper Networks <http://juniper.net>, some code has 265 been added which second-guesses the system file cache for a performance 266 boost. 267 268 * The loginfo scripting hook now runs after the administrative files in CVSROOT 269 are rebuilt, rather than before. 270 271 * Misc error message improvements. 272 273 * Thanks to funding from Juniper Networks <http://juniper.net>, new scripting 274 hooks have been added to the CVS server. These are the postadmin, posttag, 275 and postwatch hooks. See the manual for more info. 276 277 * Thanks to funding from Juniper Networks <http://juniper.net>, all the 278 existing scripting hooks may now optionally be passed a command name 279 argument. 280 281 * Thanks to funding from Juniper Networks <http://juniper.net>, new tags are 282 cached in the val-tags file at the time of tag creation. 283 284 * Thanks to a patch from Brian Murphy <brian (a] murphy.dk>, CVS now supports PAM 285 session management. 286 287 * Thanks to a report from Brian Murphy <brian (a] murphy.dk>, the demo PAM 288 configuration files mentioned in the manual are actually being distributed. 289 290 * Thanks again to Bart Robinson <lomew (a] pobox.com>, `cvs log' & `cvs ls' now 291 actually output local times when the server is version 1.12.9 or greater and 292 the client is version 1.12.10 or greater. 293 294 * The CVS server now sends paths to files relative to the repository. CVS 295 clients have been able to handle this since at least the 10 year old 296 CVS 1.9.2 release, so no attempt at verifying compatibility of clients has 297 been made. This saves a small amount of bandwidth and may enable some future 298 functionality. 299 300 * The CVS client will send relative Directory requests if the server claims to 301 support it. This saves a very small amount of bandwidth but may enable some 302 future functionality. 303 304 * "cvs import" now has a new option, `-X', which causes new files to be 305 imported in a way that they appear only on the vendor branch, and do not 306 automatically appear on the main trunk. 307 308 This option may be made the default on a repository-wide basis 309 using the new ImportNewFilesToVendorBranchOnly=yes option in 310 CVSROOT/config. 311 312 * contrib/cvs_acls.in has been revised. Users of the old version will 313 want to upgrade to use the new format. See the documentation in 314 contrib/cvs_acls.html for more information. 315 316 * Thanks to Dan Peterson <dbpete (a] aol.com>, the contrib/validate_repo script now 317 accepts and logs corrupted revision numbers in RCS archives. 318 319 BUG FIXES 320 321 * Thanks to a report from Gottfried Ganssauge <gotti (a] cvshome.org>, CVS no 322 longer exits when it encounters links pointing to paths containing more 323 than 128 characters. 324 325 * Thanks to a report from Dan Peterson <dbpete (a] aol.com>, error messages from 326 GSSAPI servers are no longer truncated. 327 328 * Thanks to a report from Dan Peterson <dbpete (a] aol.com>, attempts to resurrect 329 a file on the trunk that was added on a branch no longer causes an assertion 330 failure. 331 332 * Thanks to a report from Dan Peterson <dbpete (a] aol.com>, imports to branches 333 like "1.1." no longer create corrupt RCS archives. 334 335 * Thanks to a report from Chris Bohn <cbohn (a] rrinc.com>, links from J.C. Hamlin 336 <jchamlin (a] ibsys.com>, and code posted by Jonathan Gilligan, we think we have 337 finally corrected the Windows "red-file" (daylight savings time) bug once and 338 for all. 339 340 * Thanks to a patch from Jeroen Ruigrok/asmodai <asmodai (a] wxs.nl>, the 341 log_accum.pl script should no longer elicit warnings from Perl 5.8.5. 342 343 * The r* commands (rlog, rls, etc.) can once again handle requests to run 344 against the entire repository (e.g. `cvs rlog .'). Thanks go to Dan Peterson 345 <dbpete (a] aol.com> for the report. 346 347 * A problem where the attempted access of files via tags beginning with spaces 348 could cause the CVS server to hang has been fixed. This was a particular 349 problem with WinCVS clients because users would sometimes accidentally 350 include spaces in tags pasted into a dialog box. This fix also altered some 351 of the error messages generated by the use of invalid tags. Thanks go to Dan 352 Peterson <dbpete (a] aol.com> for the report. 353 354 * Thanks to James E Wilson <wilson (a] specifixinc.com> for a bug fix to 355 modules processing "gcc-core -a !gcc/f gcc" will no longer exclude 356 gcc/fortran by mistake. 357 358 * Thanks to Conrad Pino <conrad (a] pino.com>, the Windows build works once again. 359 360 * Misc updates to the manual. 361 362 DEVELOPER ISSUES 363 364 * We've standardized on Automake 1.9.3 to get some at new features that make 365 our jobs easier. See the note below on the Autoconf upgrade for more 366 details. 367 368 * We've standardized on Autoconf version 2.59 to get presumed bug fixes and 369 features, but nothing specific. Mostly, once we decide to upgrade one of the 370 autotools we just figure it'll save time later to grab the most current 371 versions of the others too. See the HACKING file for more on using the 372 autotools with CVS. 373 374 Changes from 1.12.8 to 1.12.9: 375 ****************************** 376 377 SERVER SECURITY FIXES 378 379 * Thanks to Stefan Esser & Sebastian Krahmer, several potential security 380 problems have been fixed. The ones which were considered dangerous enough 381 to catalogue were assigned issue numbers CAN-2004-0416, CAN-2004-0417, & 382 CAN-2004-0418 by the Common Vulnerabilities and Exposures Project. Please 383 see <http://www.cve.mitre.org> for more information. 384 385 * A potential buffer overflow vulnerability in the server has been fixed. 386 This addresses the Common Vulnerabilities and Exposures Project's issue 387 #CAN-2004-0414. Please see <http://www.cve.mitre.org> for more information. 388 389 NEW FEATURES 390 391 * `cvs log' & `cvs ls' now output local times when both the server and client 392 are 1.12.9 or greater. (Thanks to Bart Robinson <lomew (a] pobox.com>.) 393 394 DEVELOPER NOTES 395 396 * The windows-NT/config.h.in file is now generated dynamically from the 397 root config.h.in file and a few inputs in the windows-NT directory in hopes 398 of keeping it more in sync with the root config.h.in file. 399 400 Changes from 1.12.7 to 1.12.8: 401 ****************************** 402 403 SERVER SECURITY FIXES 404 405 * A potential buffer overflow vulnerability in the server has been fixed. 406 Prior to this patch, a malicious client could potentially use carefully 407 crafted server requests to run arbitrary programs on the CVS server machine. 408 This addresses the Common Vulnerabilities and Exposures Project's issue 409 #CAN-2004-0396. Please see <http://www.cve.mitre.org> for more information. 410 411 NEW FEATURES 412 413 * Some redundant output generated by the `cvs commit' command has been removed. 414 415 * Most output from the `cvs commit' command is suppressed when the -Q global 416 option is specified. 417 418 * Repository directory browsing via `cvs rls' & `cvs ls' commands. Expect 419 changes in the long format output soon. The "entries" format output should 420 remain fairly stable for automated parsers. 421 422 * Glob matches, as specified in ignore lists and wrapper options, now conform 423 to the POSIX.2 specification for fnmatch on all platforms. 424 425 * The Windows MS Visual C++ project files, including the nmake build files, 426 are now generated with MSVC++ 6.0, but should still work with MSVC++ 5.0. 427 428 BUG FIXES 429 430 * The cvs.1 man page is now generated automatically from a section of the CVS 431 Manual. 432 433 * Thanks to a report from Mark Andrews at the Internet Systems Consortium, the 434 :ext: connection method no longer relies on a transparent transport that uses 435 an argument processor that can handle arbitrary ordering of options and other 436 arguments when using a username other than the caller's. 437 438 * Thanks to Ken Raeburn at MIT, directory deletion, whether via `cvs release' 439 or empty directory pruning, now works on network shares under Windows XP. 440 441 Changes from 1.12.6 to 1.12.7: 442 ****************************** 443 444 SERVER SECURITY ISSUES 445 446 * Piped checkouts of paths above $CVSROOT no longer work. Previously, clients 447 could have requested the contents of RCS archive files anywhere on a CVS 448 server. This addresses CVE issue CAN-2004-0405. Please see 449 <http://www.cve.mitre.org> for more information. 450 451 CLIENT SECURITY ISSUES 452 453 * Clients now check paths from the server to verify that they are within one of 454 the sandboxes the user requested be updated. Previously, a trojan server 455 could have written or overwritten files anywhere the user had access, 456 presenting a serious security risk. This addresses CVE issue CAN-2004-1080. 457 Please see <http://www.cve.mitre.org> for more information. 458 459 GENERAL USER ISSUES 460 461 * Imported the most recent version of regex from GNULIB, which actually means 462 some systems will use now their native regex functions instead of compiling 463 CVS's. Users should notice no changes in CVS responses to regular 464 expressions. If you do, please report them to <bug-cvs (a] gnu.org>. 465 466 * CVS now accepts the location of HTTP tunnel web proxies as part of the 467 CVSROOT string. Actually using a proxy remains untested. Please report 468 problems and successes to <bug-cvs (a] gnu.org>. 469 470 * Configure no longer checks the $TMPDIR, $TMP, & $TEMP variables to set the 471 default temporary directory. 472 473 * CVS on Cygwin correctly handles X:\ style paths. 474 475 * Import now uses backslash rather than slash on Windows when checking for 476 "CVS" directories to ignore in import commands. 477 478 * Relative paths containing up-references (`..') should now work in 479 client/server mode (client fix). 480 481 * A race condition between the ordering of messages from CVS and messages from 482 called scripts in client/server mode has been removed (server fix). 483 484 * The check_cvs and cvscheck scripts in the contrib directory have been renamed 485 validate_repo and sandbox_status, respectively, in the interests of clarity. 486 487 * The Windows MS Visual C++ 6.0 project files have been brought up to date. 488 The nmake build files were regenerated from these files with MSVC++ 5.0. 489 490 * A memory allocation bug on Windows that could cause at least executions of 491 `cvs status' to fail has been fixed (client fix). 492 493 * Resurrected files now get their modes and timestamps set correctly and a 494 longstanding bug involving resurrection of an uncommitted removal has been 495 fixed (server fix). 496 497 * Some resurrection (cvs add) status messages have changed slightly. 498 499 * `cvs release' now works with Kerberos or GSSAPI encryption enabled (server 500 fix). 501 502 * File resurrection from a previously existing revision no longer just reports 503 that it works (server fix). 504 505 * Misc error & status message corrections. 506 507 * Diffing of locally added files against arbitrary revisions in an RCS archive 508 is now allowed when a file of the same name exists or used to exist on some 509 branch (server fix). 510 511 * Some user messages have been updated for consistency and spelling. 512 513 DEVELOPER ISSUES 514 515 * The message source differentiation in the test suite between client and 516 server executables has been repaired. 517 518 Changes from 1.12.5 to 1.12.6: 519 ****************************** 520 521 GENERAL USER ISSUES 522 523 * CVSROOT/*info scripts may not work as expected with executables compiled 524 using VC++ under Windows since all quoting is currently done according to 525 Bourne Shell rules, which probably don't look like command.com rules. 526 Patches gratefully accepted. 527 528 * Imports will now always ignore directories and files named `CVS' to avoid 529 violating assumptions made by other parts of CVS. 530 531 * Directories specified to `checkout -d' are no longer required to exist. This 532 consolidates some behavior between `-d' options specified in the modules file 533 and `checkout -d' as well as removing some prior differences between local 534 and client/server mode operation. 535 536 * A problem with `cvs release' of subdirs that could corrupt CVS/Entries files 537 has been fixed (client/server). 538 539 * The CVS server's protocol check for unused data from the client is no longer 540 called automatically at program exit in order to avoid potential recursive 541 calls to error when the first close is due to memory allocation or similar 542 problems that cause calls to error() to fail. The check is still made when 543 the server program exits normally. 544 545 * The CVSROOT/*info files want a new command format and the old style strings 546 have been deprecated. Please see the manual for more information on the new 547 format. 548 549 * The spec file has been updated to work with more recent versions of RPM. 550 551 * Some more GNULIB functions have been imported and/or updated for portability 552 reasons. 553 554 * Several memory leaks have been plugged. 555 556 * A seg fault which always occurred after waiting on another process's lock 557 in order to establish a promotable lock is now avoided. 558 559 * An unlikely potential segfault when using the :fork: connection method has 560 been fixed. 561 562 * The CVS server has had the protocol check for unused data from the client 563 partially restored. 564 565 * A fix has been included that should avoid a very rare race condition that 566 could cause a CVS server to exit with a "broken pipe" message. 567 568 * Infinite alias loops in the modules file are now checked for and avoided. 569 570 * Clients on case insensitive systems now preserve the case of directories in 571 CVS/Entries, in addition to files, for use in communications with the CVS 572 server. 573 574 * Misc status message fixes for consistency. 575 576 * Some previously untested behavior is now being tested. 577 578 * Server no longer claims to support the "Case" request. 579 580 * Case insensitive clients once again preserve the case of filenames in 581 CVS/Entries for communication with the server, as specified in the CVS 582 client/server protocol spec. Note that all CVS _servers_ still lack support 583 for case insensitive clients - servers are relying on the client to preserve 584 the case of checked out files. 585 586 * Thanks to Ville Skytt the man page has a few less spelling errors and is 587 slightly more accurate. 588 589 * Thanks to Ville Skytt some unused variables were removed from the log_accum 590 Perl script in contrib. 591 592 * Thanks to Alexey Mahotkin, a bug that prevented CVS from being compiled with 593 Kerberos 4 authentication enabled has been fixed. 594 595 * A minor bug that caused CVS to fail to report an inifinte alias loop in the 596 modules file when portions of the alias definition contained trailing slashes 597 has been fixed. 598 599 * A bug in the gzip code that could cause heap corruption and segfaults in CVS 600 servers talking to clients less than 1.8 and some modern third-party CVS 601 clients has been fixed. 602 603 * mktemp.sh is now included with the source distribution so that the rcs2log 604 and cvsbug executables may be run on systems which do not contain an 605 implementation of mktemp. 606 607 * Misc documentation fixes. 608 609 DEVELOPER ISSUES 610 611 * xmalloc, xstrdup, & some other memory allocating functions are now available 612 vi GNULIB versions imported into lib. 613 614 * The asnprintf() & vasnprintf() functions are now available due to a GNULIB 615 implementation. 616 617 * Misc cosmetic, readability, and commenting fixes. 618 619 Changes between 1.12.4 and 1.12.5: 620 ********************************** 621 622 SERVER SECURITY ISSUES 623 624 * pserver can no longer be configured to run as root via the 625 $CVSROOT/CVSROOT/passwd file, so if your passwd file is compromised, it no 626 longer leads directly to a root hack. Attempts to root will also be logged 627 via the syslog. 628 629 GENERAL USER ISSUES 630 631 * The Windows build files were updated to allow building of the current version 632 under Windows. 633 634 Changes between 1.12.3 and 1.12.4: 635 ********************************** 636 637 GENERAL USER ISSUES 638 639 * The CVS server no longer locks more than a directory at a time for write, so 640 large commits & tags should now have a much harder time blocking other 641 operations. 642 643 * Add support for large files. Use --disable-largefile to omit support 644 for large files. 645 646 Changes between 1.12.2 and 1.12.3: 647 ********************************** 648 649 SERVER SECURITY ISSUES 650 651 * Malformed module requests could cause the CVS server to attempt to create 652 directories and possibly files at the root of the filesystem holding the CVS 653 repository. Filesystem permissions usually prevent the creation of these 654 misplaced directories, but nevertheless, the CVS server now rejects the 655 malformed requests. 656 657 GENERAL USER ISSUES 658 659 * Support for case insensitive clients has been removed. This is not as 660 drastic as it sounds, as all of the current tests still pass without 661 modification when run from a case insensitive client to a case sensitive 662 server. In the end this should provide a major stability improvement. 663 664 * A minor problem that prevented the correct version of a system ZLIB from 665 being detected on some platforms has been fixed. 666 667 * Attempts to use the global `-l' option, removed from both client and server 668 as of version 1.12.1, will now elicit a warning rather than a fatal error 669 from the server. 670 671 * The configure script now tests whether it is building CVS on a case 672 insensitive file system. If it is, CVS assumes that all file systems on this 673 platform will be case insensitive. This is useful for getting the case 674 insensitivity flag set correctly when compiling on Mac OS X and under Cygwin 675 on Windows. Autodetection can be overridden using the 676 --disable-case-sensitivity and --enable-case-sensitivity arguments to 677 configure. 678 679 DEVELOPER ISSUES 680 681 * A new set of tests to test issues specific to case insensitive clients and 682 servers has also been added. 683 684 * Support has been added to the test suite to support testing over a :ext: link 685 to another machine, subject to some stringent requirements. This support can 686 be used, for instance, to test the operation of a case insensitive client 687 against a case sensitive server. Please see the comments in TEST and the 688 src/sanity.sh test script itself for more. 689 690 * We've standardized on Automake 1.7.9 to get a bug fix. See the note below 691 on the Autoconf upgrade for more details. 692 693 * We've standardized on Autoconf version 2.58 to avoid a bug and get at a few 694 new macros. Again, this should only really affect developers, though it is 695 possible that CVS will now compile on a few new platforms. Please see the 696 section of the INSTALL file about using the autotools if you are compiling 697 CVS yourself. 698 699 Changes between 1.12.1 and 1.12.2: 700 701 * Misc cleanup, reorganization, and other minor fixes. 702 703 * A behavior change in `cvs up -jrev1 -jrev2' for modified files with a base 704 revision of rev2 (ie, checked-out version matches rev2 and file has been 705 modified). The operation is no longer ignored and instead is passed to 706 diff3. This will potentially re-apply the diffs between the two revisions to 707 a modified local file. Status messages like from a standard merge have also 708 been added when the file would not or does not change due to this merge 709 request ("[file] already contains the changes between [revisions]..."). 710 711 * A build problem that caused warnings and slower builds on systems without a 712 working getline() function (e.g. Mac OS X 10.1) has been fixed. 713 714 * A build problem that prevented the CVS executable from being built on systems 715 with the gettext library installed has been fixed. 716 717 * A bug which could stop `cvs admin -mTAG:message' from recursing has been 718 fixed. 719 720 * Misc documentation cleanup and fixes. 721 722 * Some of the contrib scripts, some of the documentation, and sanity.sh were 723 modified to use and recommend more portable commands rather than using and 724 recommending commands which were not compatible with the POSIX 1003.1-2001 725 specification. 726 727 * CVS now knows how to report, as well as record, `P' record types. 728 729 * When running the `cvs history' command, clients will now send the 730 long-accepted `-e' option, for all records, rather than explicitly requesting 731 `P' record types, a request which servers prior to 1.11.7 will reject with a 732 fatal error message. 733 734 * A problem with locating files requested by case insensitive clients which was 735 accidentally introduced in 1.11.6 as part of a fix for a data loss problem 736 involving `cvs add's from case insensitive clients has been fixed. The 737 relevant error message was `cvs [<command> aborted]: filE,v is ambiguous; 738 could mean FILE,v or file,v'. 739 740 * A problem in the CVS getpass library that could cause passwords to echo on 741 some systems has been fixed. 742 743 * A segfault that could occur in very rare cases where the stat of a file 744 failed during a diff has been fixed. 745 746 * Any user with write privleges to the CVSROOT/checkoutlist file could pass 747 arbitrary format strings directly through to a printf function. This was 748 probably bad and has been fixed. White space at the beginning of error strings 749 in checkoutlist is now ignored properly. 750 751 * A chmod 0600 that CVS performed on temp files it created designed to work 752 around a bug in versions of GLIBC eariler than 2.0.7 has been removed since it 753 still left a race condition open to exploitation and provided a false sense of 754 security. If you are linking CVS against a version of GLIBC prior to 2.0.7, 755 you should consider upgrading GLIBC. 756 757 * The CVSROOT/editinfo file is no longer referenced by CVS. This funcitonality 758 has been deprecated for over six years and removing it will presumably not 759 cause anyone any problems. 760 761 * In client/server mode, most messages from CVS now contain the actual 762 command name rather than the generic "server". 763 764 * A long-standing bug that prevented most client/server updates from being 765 logged in the history file has been fixed. 766 767 * Updates done via a patch ("P" status) are now logged in the history file 768 by default and the corresponding "P" history record type is now documented. 769 If you're setting the LogHistory option in your CVSROOT/config file, you may 770 want to add "P" to the list of record types. 771 772 * CVS now will always compile its own getpass() function (originally from 773 GNULIB) in favor of any system one that may exist. This avoids some problems 774 with long passwords on some systems and updates us to POSIX.2 compliance, since 775 getpass() was removed from the POSIX.2 specification. 776 777 * Support for pre-ANSI compilers has been removed. Our minimum support level 778 now assumes at least a freestanding C89 compilers. See the HACKING file for 779 more information. If you *really* need K&R support, our Makefile.am files 780 should only need minor tweaking to get them to run the ansi2knr script from the 781 Automake project. If you get this working, please send a patch to 782 <bug-cvs (a] gnu.org>. 783 784 * Experimental support for Pluggable Authentication Modules (PAM) has been 785 added, though it is not compiled by default. If you like this feature (or 786 don't), please send us feedback. See the Cederqvist, `./configure --help', 787 and the INSTALL file for more. 788 789 * Command line keyword expansion modes no longer override binary keyword 790 expansion modes. 791 792 * New LocalKeyword and KeywordExpand options to CVSROOT/config which 793 FreeBSD, OpenBSD, and NetBSD users may find familiar as the "tag" and 794 "tagexpand" options used for many years. The CVSHeader keyword has 795 also been added to the mixture. 796 797 * A bug that allowed a write lock to be created in a directory despite 798 there being existing read locks when using LockDir in CVSROOT/config has 799 been fixed. 800 801 * A bug with short patches (`rdiff -s') which caused rdiff to sometimes report 802 differences that did not exist has been fixed. 803 804 * Some minor corrections were made to the diff code to keep diff & rdiff from 805 printing diff headers with empty change texts when two files have different 806 revision numbers but the same content. 807 808 * The global '-l' option, which suppressed history logging, has been removed 809 from both client and server. 810 811 Changes from 1.11.5 to 1.12.1: 812 813 * The new --with-external-zlib option can be passed to configure to compile 814 CVS against an external installed zlib. 815 816 * A warning message is now issued if an administrative file contains 817 more than one DEFAULT entry. 818 819 * An error running a verifymsg script (such as referencing an unset user 820 variable or the script not existing) now causes the verification to 821 fail. 822 823 * Errors in administrative files commands (like unset user variables) 824 are no longer reported unless the command is actually executed. 825 826 * When a file is initially checked out, its last access time is now set 827 to the current time rather than being set to the time the file was last 828 checked in like the modification time is. 829 830 * The Checkin.prog and Update.prog functionality has been removed. This 831 fuctionality previously allowed executables to be specified in the modules file 832 to be run at update and checkin time, but users could edit these files on a per 833 workspace basis, creating a security hole. 834 835 * CVSROOTs which contain a symlink to a real repository should work. 836 837 * contrib/rcs2log and src/cvsbug now use the BSD mktemp program to create 838 their temp files and directories on systems which provide it. 839 840 * Added a UserAdminOptions configuration option to CVSROOT/config to 841 control which `cvs admin' commands are not restricted to the `cvsadmin' 842 group. 843 844 * If the rcsinfo specified template changes after a user has checked 845 out a tree, the template in the users' tree will be updated rather 846 than remaining static from the time of the original checkout. 847 848 * Added a CVSREADONLYFS environment variable and `-R' cvs global 849 option to turn on read-only repository mode for local repositories. 850 This allows users to checkout from a CDROM repository or other 851 read-only filesystem. 852 853 * There is a new CVS_LOCAL_BRANCH_NUM environment variable, which 854 may be used to give control over the branch number to be used next. 855 Useful for having local changes in a CVSup mirrored repository. 856 857 * Miscellaneous documentation corrections. 858 859 * Corrected the path in a failed write error message. 860 861 * Autoconf and Automake are no longer run automatically unless you run 862 configure with --enable-maintainer-mode. Accordingly, noautomake.sh is 863 no longer needed and has been removed. 864 865 * We've standardized on Automake version 1.7.5 and Autoconf version 2.57 to get 866 at a few new macros. Again, this should only really affect developers. See 867 the section of the INSTALL file about using the autotools if you are compiling 868 CVS yourself. 869 870 Changes from 1.11.4 to 1.11.5: 871 872 * Fixed a security hole in the CVS server by which users with read only access 873 could gain write access. This issue does not affect client builds. The 874 Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the 875 name CAN-2003-0015 to this issue. See 876 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0015> for more 877 information. 878 879 * Fixed some bugs where revision numbers starting with 0 (like 0.3) 880 weren't correctly handled. (CVS doesn't normally use such revision 881 numbers, but users may be able to force it to do so and old RCS files 882 might.) 883 884 Changes from 1.11.3 to 1.11.4: 885 886 * Some minor changes to allow the code to compile on Windows platforms. 887 888 Changes from 1.11.2 to 1.11.3: 889 890 * The tag/rtag code has been fixed to once again lock just a single 891 directory at a time. 892 893 * There was a bug where certain error conditions could cause the server 894 to go into an infinite loop. There was also a bug that caused a 895 compressed connection from an older client to hang on shutdown. These 896 bugs have been fixed. 897 898 * Fixed a bug that caused the server to reject most watch commands. 899 900 * When waiting for another user's lock, the message timestamps are now 901 in UTC rather than the server's local time. 902 903 * The options.h file is no longer used. This fixes a bug that occurred when 904 1.11.2 was compiled on Windows platforms. 905 906 * We've standardized on Automake version 1.6.3 and Autoconf version 2.53. 907 They are cleaner, less bug prone, and will hopfully allow me to start updating 908 sanity.sh to use Autotest and Autoshell. Again, this should only really affect 909 developers. See the section of the INSTALL file about using the autotools if 910 you are compiling CVS yourself. 911 912 * Fixed a bug in the log/rlog code when a revision range crosses a 913 branch point. 914 915 * Fixed a bug where filenames starting with - would be misinterpreted as 916 options when using client/server mode. 917 918 Changes from 1.11.1p1 to 1.11.2: 919 920 * There is a new feature, enabled by RereadLogAfterVerify in CVSROOT/config, 921 which tells CVS to reread the log message after running the verifymsg 922 script. This allows the verifymsg script to reformat or otherwise 923 modify the log message. 924 925 * The interpretation of revision ranges using :: in "log" and "rlog" 926 has changed: a::b now excludes the log message from revision a but 927 includes the log message from revision b. Also, revision ranges that 928 cross branch points should now work. 929 930 * zlib has been updated to version 1.4. There is a security advisory 931 out in regards to 1.3. This should fix that problem. 932 933 * The "log" and "rlog" commands now have a -S option to suppress the 934 header information when no revisions are selected. 935 936 * A serious error that allowed read-only users to tag files has been 937 corrected. 938 939 * The "annotate" command will no longer annotate binary files unless 940 you specify the new -F option. 941 942 * The "tag" and "rtag" commands will no longer move or delete branch 943 tags unless you use the new -B option. (This prevents accidental 944 changes to branch tags that are hard to undo.) 945 946 * We've standardized on the 1.5 Automake release for the moment. Again, this 947 should only really affect developers. See the section of the INSTALL file 948 about using the autotools if you are compiling CVS yourself. 949 950 Changes from 1.11.1 to 1.11.1p1: 951 952 * Read only access was broken - now fixed. 953 954 Changes from 1.11 to 1.11.1: 955 956 * There was a locking bug in the tag/rtag code that could lose changes 957 made to a file while the tag operation was in progress. This has been 958 fixed, but all of the directories being tagged are now locked for the 959 entire duration of the tag operation rather than only one directory at a 960 time. 961 962 * The "cvs diff" command now accepts the -y/--side=by-side and -T/ 963 --initial-tab options. (To use these options with a remote repository, 964 both the client and the server must support them.) 965 966 * The expansion of the loginfo format string has changed slightly. 967 Previously, the expansion was surrounded by single quotes ('); if a file 968 name contained a single quote character, the string would not be parsed 969 as a single entity by the Unix shell (and it would not be possible to 970 parse it unambiguously). Now the expansion is surrounded by double 971 quotes (") and any embedded dollar signs ($), backticks (`), backslashes 972 (\), and double quotes are preceded by a backslash. This is parsed as a 973 single entity by the shell reguardless of content. This change should 974 not be noticable unless you're not using a Unix shell or you have 975 embedded the format string inside a double quoted string. 976 977 * There was a bug in the diff code which sometimes caused conflicts to 978 be flagged which shouldn't have been. This has been fixed. 979 980 * New "cvs rlog" and "cvs rannotate" commands have been added to get log 981 messages and annotations without having to have a checked-out copy. 982 983 * Exclusive revision ranges have been added to "cvs log" using :: 984 (similar to "cvs admin -o"). 985 986 * The VMS client now accepts wildcards if you're running VMS 7.x. 987 988 * ZLIB has been updated to version 1.1.3, the most current version. This 989 includes mostly some optimizations and minor bug fixes. 990 991 * The ~/.cvspass file has a slightly modified format. CVSROOTs are now 992 stored in a new canonical form - hostnames are now case insensitive and 993 port numbers are always stored in the new format. Until a new login for 994 a particular CVSROOT is performed with the new version of CVS, new and 995 old versions of CVS should interoperate invisibly. After that point, an 996 extra login using the old version of CVS may be necessary to continue to 997 allow the new and old versions of CVS to interoperate using the same 998 ~/.cvspass file and CVSROOT. The exception to this rule occurs when the 999 CVSROOTs used with the different versions use case insensitively 1000 different hostnames, for example, "empress", and "empress.2-wit.com". 1001 1002 * A password and a port number may now be specified in CVSROOT for 1003 pserver connections. The new format is: 1004 1005 :pserver:[[user][:password]@]host[:[port]]/path 1006 1007 Note that passwords specified in a checkout command will be saved in the 1008 clear in the CVS/Root file in each created directory, so this is not 1009 recommended, except perhaps when accessing anonymous repositories or the 1010 like. 1011 1012 * The distribution has been converted to use Automake. This shouldn't 1013 affect most users except to ease some portability concerns, but if you 1014 are building from the repository and encounter problems with the 1015 makefiles, you might try running ./noautomake.sh after a fresh update 1016 -AC. 1017 1018 Changes from 1.10 to 1.11: 1019 1020 * The "cvs update" command has a new -C option to get clean copies from 1021 the repository, abandoning any local changes. 1022 1023 * The new "cvs version" command gives a short version message. If 1024 the repository is remote, both the client and server versions are 1025 reported. 1026 1027 * "cvs admin -t" now works correctly in client/server mode. 1028 1029 * The "cvs history" command output format has changed -- the date 1030 now includes the year and is given is ISO 8601 format (yyyy-mm-dd). 1031 Also, the new LogHistory option in CVSROOT/config can be used to 1032 control what information gets recorded in the log file and code has 1033 been added to record file removals. 1034 1035 * The buggy PreservePermissions code has been disabled. 1036 1037 * Anonymous read-only access can now be done without requiring a 1038 password. On the server side, simply give that user (presumably 1039 `anonymous') an empty password in the CVSROOT/passwd file, and then 1040 any received password will authenticate successfully. 1041 1042 * There is a new access method :fork: which is similar to :local: 1043 except that it is implemented via the CVS remote protocol, and thus 1044 has a somewhat different set of quirks and bugs. 1045 1046 * The -d command line option no longer updates the CVS/Root file. For 1047 one thing, the CVS 1.9/1.10 behavior never had updated CVS/Root in 1048 subdirectories, and for another, it didn't seem that popular in 1049 general. So this change restores the CVS 1.8 behavior (which is also 1050 the CVS 1.9/1.10 behavior if the environment variable 1051 CVS_IGNORE_REMOTE_ROOT is set; with this change, 1052 CVS_IGNORE_REMOTE_ROOT no longer has any effect). 1053 1054 * It is now possible for a single CVS command to recurse into several 1055 CVS roots. This includes roots which are located on several servers, 1056 or which are both remote and local. CVS will make connections to as 1057 many servers as necessary. 1058 1059 * It is now possible to put the CVS lock files in a directory 1060 set by the new LockDir option in CVSROOT/config. The default 1061 continues to be to put the lock files in the repository itself. 1062 1063 Changes from 1.9 to 1.10: 1064 1065 * A bug was discovered in the -t/-f wrapper support that can cause 1066 serious data loss. Because of this (and also the fact that it doesn't 1067 work at all in client/server mode), the -t/-f wrapper code has been 1068 disabled until it can be fixed. 1069 1070 * There is a new feature, enabled by TopLevelAdmin in CVSROOT/config, 1071 which tells CVS to modify the behavior of the "checkout" command. The 1072 command now creates a CVS directory at the top level of the new 1073 working directory, in addition to CVS directories created within 1074 checked-out directories. See the Cederqvist for details. 1075 1076 * There is an optional set of features, enabled by PreservePermissions 1077 in CVSROOT/config, which allow CVS to store unix-specific file 1078 information such as permissions, file ownership, and links. See the 1079 Cederqvist for details. 1080 1081 * One can now authenticate and encrypt using the GSSAPI network 1082 security interface. For details see the Cederqvist's description of 1083 specifying :gserver: in CVSROOT, and the -a global option. 1084 1085 * All access to RCS files is now implemented internally rather than by 1086 calling RCS programs. The main user-visible consequence of this is 1087 that there is no need to worry about making sure that CVS finds the 1088 correct version of RCS. The -b global option and the RCSBIN setting 1089 in CVSROOT/config are still accepted but don't do anything. The 1090 $RCSBIN internal variable in administrative files is no longer 1091 accepted. 1092 1093 * There is a new syntax, "cvs admin -orev1::rev2", which collapses the 1094 revisions between rev1 and rev2 without deleting rev1 or rev2 1095 themselves. 1096 1097 * There is a new administrative file CVSROOT/config which allows one 1098 to specify miscellaneous aspects of CVS configuration. Currently 1099 supported here: 1100 1101 - SystemAuth, allows you to prevent pserver from checking for system 1102 usernames/passwords. 1103 1104 For more information see the "config" section of cvs.texinfo. 1105 1106 * When setting up the pserver server, one now must specify the 1107 allowable CVSROOT directories in inetd.conf. See the Password 1108 authentication server section of cvs.texinfo for details. Note that 1109 this implies that everyone who is running a pserver server must edit 1110 inetd.conf when upgrading their CVS. 1111 1112 * The client no longer needs an external patch program (assuming both 1113 the client and the server have been updated to the new version). 1114 1115 * "cvs admin [options]" will now recurse. In previous versions of 1116 CVS, it was an error and one needed to specify "cvs admin [options] ." 1117 to recurse. This change brings admin in line with the other CVS 1118 commands. 1119 1120 * New "logout" command to remove the password for a remote cvs 1121 repository from the cvspass file. 1122 1123 * Read-only repository access is implemented for the 1124 password-authenticated server (other access methods are just governed 1125 by Unix file permissions, since they require login access to the 1126 repository machine anyway). See the "Repository" section of 1127 cvs.texinfo for details, including a discussion of security issues. 1128 Note that the requirement that read-only users be able to create locks 1129 and write the history file still applies. 1130 1131 * There is a new administrative file verifymsg which is like editinfo 1132 but merely validates the message, rather than also getting it from the 1133 user. It therefore works with client/server CVS or if one uses the -m 1134 or -F options to commit. See the verifymsg section of cvs.texinfo for 1135 details. 1136 1137 * The %s format formerly accepted in loginfo has been extended to 1138 formats such as %{sVv}, so that loginfo scripts have access to the 1139 version numbers being changed. See the Loginfo section of cvs.texinfo 1140 for details. 1141 1142 * The postscript documentation (doc/cvs.ps) shipped with CVS is now 1143 formatted for US letter size instead of A4. This is not because we 1144 consider this size "better" than A4, but because we believe that the 1145 US letter version will print better on A4 paper than the other way 1146 around. 1147 1148 * The "cvs export" command is now logged in the history file and there 1149 is a "cvs history -x E" command to select history file entries 1150 produced by export. 1151 1152 * CVS no longer uses the CVS_PASSWORD environment variable. Storing 1153 passwords in cleartext in an environment variable is a security risk, 1154 especially since (on BSD variants) any user on the system can display 1155 any process's environment using 'ps'. Users should use the 'cvs 1156 login' command instead. 1157 1158 1159 Changes from 1.8 to 1.9: 1160 1161 * Windows NT client should now work on Windows 95 as well. 1162 1163 * New option "--help-synonyms" prints a list of all recognized command 1164 synonyms. 1165 1166 * The "log" command is now implemented internally rather than via the 1167 RCS "rlog" program. The main user-visible consequence is that 1168 symbolic branch names now work (for example "cvs log -rbranch1"). 1169 Also, the date formats accepted by -d have changed. They previously 1170 had been a bewildering variety of poorly-documented date formats. Now 1171 they are the same as the date formats accepted by the -D options to 1172 the other CVS commands, which is also a (different) bewildering 1173 variety of poorly-documented date formats, but at least we are 1174 consistently bewildering :-). 1175 1176 * Encryption is now supported over a Kerberos client/server 1177 connection. The new "-x" global option requests it. You must 1178 configure with the --enable-encryption option in order to enable 1179 encryption. 1180 1181 * The format of the CVS commit message has changed slightly when 1182 committing changes on a branch. The tag on which the commit is 1183 ocurring is now reported correctly in all cases. 1184 1185 * New flag -k in wrappers allows you to specify the keyword expansion 1186 mode for added files based on their name. For example, you can 1187 specify that files whose name matches *.exe are binary by default. 1188 See the Wrappers section of cvs.texinfo for more details. 1189 1190 * Remote CVS with the "-z" option now uses the zlib library (included 1191 with CVS) to compress all communication between the client and the 1192 server, rather than invoking gzip on each file separately. This means 1193 that compression is better and there is no need for an external gzip 1194 program (except to interoperate with older version of CVS). 1195 1196 * The "cvs rlog" command is deprecated and running it will print a 1197 warning; use the synonymous "cvs log" command instead. It is 1198 confusing for rlog to mean the same as log because some other CVS 1199 commands are in pairs consisting of a plain command which operates on 1200 a working directory and an "r" command which does not (diff/rdiff; 1201 tag/rtag). 1202 1203 * "cvs diff" has a bunch of new options, mostly long options. Most of 1204 these work only if rcsdiff and diff support them, and are named the 1205 same as the corresponding options to diff. 1206 1207 * The -q and -Q command options to "cvs diff" were removed (use the 1208 global options instead). This brings "cvs diff" into line with the 1209 rest of the CVS commands. 1210 1211 * The "annotate" command can now be used to annotate a revision other 1212 than the head revision on the trunk (see the -r, -D, and -f options in 1213 the annotate node of cvs.texinfo for details). 1214 1215 * The "tag" command has a new option "-c" which checks that all files 1216 are not locally modified before tagging. 1217 1218 * The -d command line option now overrides the cvsroot setting stored 1219 in the CVS/Root file in each working directory, and specifying -d will 1220 cause CVS/Root to be updated. 1221 1222 * Local (non-client/server) CVS now runs on Windows NT. See 1223 windows-NT/README for details. 1224 1225 * The CVSROOT variable specification has changed to support more 1226 access methods. In addition to "pserver," "server" (internal rsh 1227 client), "ext" (external rsh client), "kserver" (kerberos), and 1228 "local" (local filesystem access) can now be specified. For more 1229 details on each method, see cvs.texinfo (there is an index entry for 1230 :local: and each of the other access methods). 1231 1232 * The "login" command no longer prompts the user for username and 1233 hostname, since one will have to provide that information via the `-d' 1234 flag or by setting CVSROOT. 1235 1236 Changes from 1.7 to 1.8: 1237 1238 * New "cvs annotate" command to display the last modification for each 1239 line of a file, with the revision number, user checking in the 1240 modification, and date of the modification. For more information see 1241 the `annotate' node in cvs.texinfo. 1242 1243 * The cvsinit shell script has been replaced by a cvs init command. 1244 The cvs init command creates some example administrative files which 1245 are similar to the files found in the examples directory (and copied 1246 by cvsinit) in previous releases. 1247 1248 * Added the patterns *.olb *.exe _$* *$ to default ignore list. 1249 1250 * There is now a $USER internal variable for *info files. 1251 1252 * There is no longer a separate `mkmodules' program; the functionality 1253 is now built into `cvs'. If upgrading an old repository, it is OK to 1254 leave in the lines in the modules file which run mkmodules (the 1255 mkmodules actions will get done twice, but that is harmless); you will 1256 probably want to remove them once you are no longer using the old CVS. 1257 1258 * One can now specify user variables in *info files via the 1259 ${=varname} syntax; there is a -s global option to set them. See the 1260 Variables node in cvs.texinfo for details. 1261 1262 Changes from 1.6 to 1.7: 1263 1264 * The default ignore list has changed slightly: *.obj has been added 1265 and CVS* has been changed to CVS CVS.adm. 1266 1267 * CVS now supports password authentication when accessing remote 1268 repositories; this is useful for sites that can't use rsh (because of 1269 a firewall, for example), and also don't have kerberos. See node 1270 "Password authenticated" (in "Remote repositories", in 1271 doc/cvs.texinfo) for more details. Note: This feature requires both 1272 the client and server to be upgraded. 1273 1274 * Using the -kb option to specify binary files now works--most cases 1275 did not work before. See the "Binary files" section of 1276 doc/cvs.texinfo for details. 1277 1278 * New developer communication features. See the "Watches" section of 1279 doc/cvs.texinfo for details. 1280 1281 * RCS keyword "Name" supported for "cvs update -r <tag>" and "cvs 1282 checkout -r <tag>". 1283 1284 * If there is a group whose name matches a compiled in value which 1285 defaults to "cvsadmin", only members of that group can use "cvs 1286 admin". This replaces the CVS_NOADMIN option. 1287 1288 * CVS now sets the modes of files in the repository based on the 1289 CVSUMASK environment variable or a compiled in value defaulting to 1290 002. This way other developers will be able to access the files in 1291 the repository regardless of the umask of the developer creating them. 1292 1293 * The command names in .cvsrc now match the official name of the 1294 command, not the one (possibly an alias) by which it was invoked. If 1295 you had previously relied on "cvs di" and "cvs diff" using different 1296 options, instead use a shell function or alias (for example "alias 1297 cvsdi='cvs diff -u'"). You also can specify global CVS options (like 1298 "-z") using the command name "cvs". 1299 1300 Changes from 1.5 to 1.6: 1301 1302 * Del updated the man page to include all of the new features 1303 of CVS 1.6. 1304 1305 * "cvs tag" now supports a "-r | -D" option for tagging an already 1306 tagged revision / specific revision of a file. 1307 1308 * There is a "taginfo" file in CVSROOT that supports filtering and 1309 recording of tag operations. 1310 1311 * Long options support added, including --help and --version options. 1312 1313 * "cvs release" no longer cares whether or not the directory being 1314 released has an entry in the `modules' file. 1315 1316 * The modules file now takes a -e option which is used instead of -o 1317 for "cvs export". If your modules file has a -o option which you want 1318 to be used for "cvs export", change it to specify -e as well as -o. 1319 1320 * "cvs export" now takes a -k option to set RCS keyword expansion. 1321 This way you can export binary files. If you want the old behavior, 1322 you need to specify -kv. 1323 1324 * "cvs update", "cvs rdiff", "cvs checkout", "cvs import", "cvs 1325 release", "cvs rtag", and "cvs tag" used to take -q and -Q options 1326 after the command name (e.g. "cvs update -q"). This was confusing 1327 because other commands, such as "cvs ci", did not. So the options 1328 after the command name have been removed and you must now specify, for 1329 example, "cvs -q update", which has been supported since CVS 1.3. 1330 1331 * New "wrappers" feature. This allows you to set a hook which 1332 transforms files on their way in and out of cvs (apparently on the 1333 NeXT there is some particular usefulness in tarring things up in the 1334 repository). It also allows you to declare files as merge-by-copy 1335 which means that instead of trying to merge the file, CVS will merely 1336 copy the new version. There is a CVSROOT/cvswrappers file and an 1337 optionsl ~/.cvswrappers file to support this feature. 1338 1339 * You can set CVSROOT to user@host:dir, not just host:dir, if your 1340 username on the server host is different than on the client host. 1341 1342 * VISUAL is accepted as well as EDITOR. 1343 1344 * $CVSROOT is expanded in *info files. 1345 1346 Changes from 1.4A2 to 1.5: 1347 1348 * Remote implementation. This is very helpful when collaborating on a 1349 project with someone across a wide-area network. This release can 1350 also be used locally, like other CVS versions, if you have no need for 1351 remote access. 1352 1353 Here are some of the features of the remote implementation: 1354 - It uses reliable transport protocols (TCP/IP) for remote repository 1355 access, not NFS. NFS is unusable over long distances (and sometimes 1356 over short distances) 1357 - It transfers only those files that have changed in the repository or 1358 the working directory. To save transmission time, it will transfer 1359 patches when appropriate, and can compress data for transmission. 1360 - The server never holds CVS locks while waiting for a reply from the client; 1361 this makes the system robust when used over flaky networks. 1362 1363 The remote features are documented in doc/cvsclient.texi in the CVS 1364 distribution, but the main doc file, cvs.texinfo, has not yet been 1365 updated to include the remote features. 1366 1367 * Death support. See src/README-rm-add for more information on this. 1368 1369 * Many speedups, especially from jtc (a] cygnus.com. 1370 1371 * CVS 1.2 compatibility code has been removed as a speedup. If you 1372 have working directories checked out by CVS 1.2, CVS 1.3 or 1.4A2 will 1373 try to convert them, but CVS 1.5 and later will not (if the working 1374 directory is up to date and contains no extraneous files, you can just 1375 remove it, and then check out a new working directory). Likewise if 1376 your repository contains a CVSROOT.adm directory instead of a CVSROOT 1377 directory, you need to rename it. 1378 1379 Fri Oct 21 20:58:54 1994 Brian Berliner <berliner (a] sun.com> 1380 1381 * Changes between CVS 1.3 and CVS 1.4 Alpha-2 1382 1383 * A new program, "cvsbug", is provided to let you send bug reports 1384 directly to the CVS maintainers. Please use it instead of sending 1385 mail to the info-cvs mailing list. If your build fails, you may 1386 have to invoke "cvsbug" directly from the "src" directory as 1387 "src/cvsbug.sh". 1388 1389 * A new User's Guide and Tutorial, written by Per Cederqvist 1390 <ceder (a] signum.se> of Signum Support. See the "doc" directory. A 1391 PostScript version is included as "doc/cvs.ps". 1392 1393 * The Frequesntly Asked Questions file, FAQ, has been added to the 1394 release. Unfortunately, its contents are likely out-of-date. 1395 1396 * The "cvsinit" shell script is now installed in the $prefix/bin 1397 directory like the other programs. You can now create new 1398 CVS repositories with great ease. 1399 1400 * Index: lines are now printed on output from 'diff' and 'rdiff', 1401 in order to facilitate application of patches to multiple subdirs. 1402 1403 * Support for a ~/.cvsrc file, which allows you to specify options 1404 that are always supposed to be given to a specific command. This 1405 feature shows the non-orthogonality of the option set, since while 1406 there may be an option to turn something on, the option to turn 1407 that same thing off may not exist. 1408 1409 * You can now list subdirectories that you wish to ignore in a 1410 modules listing, such as: 1411 1412 gcc -a gnu/gcc, !gnu/gcc/testsuites 1413 1414 which will check out everything underneath gnu/gcc, except 1415 everything underneath gnu/gcc/testsuites. 1416 1417 * It is now much harder to accidentally overwrite an existing tag 1418 name, since attempting to move a tag name will result in a error, 1419 unless the -F (force) flag is given to the tag subcommands. 1420 1421 * Better error checking on matching of the repository used to 1422 check code out from against the repository the current cvs 1423 commnands would use. (Thanks to Mark Baushke <mdb (a] cisco.com>) 1424 1425 * Better support for sites with multiple CVSROOT repositories has 1426 been contributed. The file "CVS/Root" in your working directory 1427 is created to hold the full path to the CVS repository and a 1428 simple check is made against your current CVSROOT setting. 1429 1430 * You can now specify an RCS keyword substitution value when you 1431 import files into the repository. 1432 1433 * Uses a much newer version of Autoconf, and conforms to the GNU 1434 coding standards much more closely. No, it still doesn't have 1435 long option names. 1436 1437 * Code cleanup. Many passes through gcc -Wall helped to identify 1438 a number of questionable constructs. Most arbitrary length limits 1439 were removed. 1440 1441 * Profiling to determine bottlenecks helped to identify the best 1442 places to spend time speeding up the code, which was then done. A 1443 number of performance enhancements in filename matching have sped 1444 up checkouts. 1445 1446 * Many more contributions have been added to the "contrib" 1447 directory. See the README file in that directory for more 1448 information. 1449 1450 * "cvs commit" will try harder to not change the file's 1451 modification time after the commit. If the file does not change 1452 as a result of the commit operation, CVS will preserve the 1453 original modification time, thus speeding up future make-type 1454 builds. 1455 1456 * "cvs commit" now includes any removed files in the (optional) 1457 pre-commit checking program that may be invoked. Previously, only 1458 added and modified files were included. 1459 1460 * It is now possible to commit a file directly onto the trunk at a 1461 specific revision level by doing "cvs commit -r3.0 file.c", where 1462 "3.0" specifies the revision you wish to create. The file must be 1463 up-to-date with the current head of the trunk for this to succeed. 1464 1465 * "cvs commit" will now function with a pre-commit program that 1466 has arguments specified in the "commitinfo" file. 1467 1468 * The "mkmodules" program will now look within the 1469 $CVSROOT/CVSROOT/checkoutlist" file for any additional files that 1470 should be automatically checked out within CVSROOT; mkmodules also 1471 tries harder to preserve any execute bits the files may have 1472 originally had. 1473 1474 * "cvs diff" is much more accurate about its exit status now. It 1475 now returns the maximum exit status of any invoked diff. 1476 1477 * The "-I !" option is now supported for the import and update 1478 commands correctly. It will properly clear the ignore list now. 1479 1480 * Some problems with "cvs import" handling of .cvsignore have been 1481 fixed; as well, some rampant recursion problems with import have 1482 also been fixed. 1483 1484 * "cvs rdiff" (aka "cvs patch") now tries to set the modify time 1485 of any temporary files it uses to match those specified for the 1486 particular revision. This allows a more accurate patch image to 1487 be created. 1488 1489 * "cvs status" has improved revision descriptions. "Working 1490 revision" is used for the revision of the working file that you 1491 edit directly; "Repository revision" is the revision of the file 1492 with the $CVSROOT source repository. Also, the output is clearer 1493 with regard to sticky and branch revisions. 1494 1495 * CVS no longer dumps core when given a mixture of directories and 1496 files in sub-directories (as in "cvs ci file1 dir1/file2"). 1497 Instead, arguments are now clumped into their respective directory 1498 and operated on in chunks, together. 1499 1500 * If the CVSEDITOR environment variable is set, that editor is 1501 used for log messages instead of the EDITOR environment variable. 1502 This makes it easy to substitute intelligent programs to make more 1503 elaborate log messages. Contributed by Mark D Baushke 1504 (mdb (a] cisco.com). 1505 1506 * Command argument changes: 1507 cvs: The "-f" option has been added to ignore 1508 the ~/.cvsrc file. 1509 commit: Renamed the "-f logfile" option to the 1510 "-F logfile" option. Added the "-f" 1511 option to force a commit of the specified 1512 files (this disables recursion). 1513 history: Added "-t timezone" option to force any 1514 date-specific output into the specified 1515 timezone. 1516 import: Added "-d" option to use the file's 1517 modification time as the time of the 1518 import. Added "-k sub" option to set the 1519 default RCS keyword substitution mode for 1520 newly-created files. 1521 remove: Added "-f" option to force the file's 1522 automatic removal if it still exists in 1523 the working directory (use with caution). 1524 rtag: Added "-F" option to move the tag if it 1525 already exists -- new default is to NOT 1526 move tags automatically. 1527 tag: Added "-F" option to move the tag if it 1528 already exists -- new default is to NOT 1529 move tags automatically. 1530 1531 Tue Apr 7 15:55:25 1992 Brian Berliner (berliner at sun.com) 1532 1533 * Changes between CVS 1.3 Beta-3 and official CVS 1.3! 1534 1535 * A new shell script is provided, "./cvsinit", which can be run at 1536 install time to help setup your $CVSROOT area. This can greatly 1537 ease your entry into CVS usage. 1538 1539 * The INSTALL file has been updated to include the machines on 1540 which CVS has compiled successfully. I think CVS 1.3 is finally 1541 portable. Thanks to all the Beta testers! 1542 1543 * Support for the "editinfo" file was contributed. This file 1544 (located in $CVSROOT/CVSROOT) can be used to specify a special 1545 "editor" to run on a per-directory basis within the repository, 1546 instead of the usual user's editor. As such, it can verify that 1547 the log message entered by the user is of the appropriate form 1548 (contains a bugid and test validation, for example). 1549 1550 * The manual pages cvs(1) and cvs(5) have been updated. 1551 1552 * The "mkmodules" command now informs you when your modules file 1553 has duplicate entries. 1554 1555 * The "add" command now preserves any per-directory sticky tag when 1556 you add a new directory to your checked-out sources. 1557 1558 * The "admin" command is now a fully recursive interface to the 1559 "rcs" program which operates on your checked-out sources. It no 1560 longer requires you to specify the full path to the RCS file. 1561 1562 * The per-file sticky tags can now be effectively removed with 1563 "cvs update -A file", even if you had checked out the whole 1564 directory with a per-directory sticky tag. This allows a great 1565 deal of flexibility in managing the revisions that your checked-out 1566 sources are based upon (both per-directory and per-file sticky 1567 tags). 1568 1569 * The "cvs -n commit" command now works, to show which files are 1570 out-of-date and will cause the real commit to fail, or which files 1571 will fail any pre-commit checks. Also, the "cvs -n import ..." 1572 command will now show you what it would've done without actually 1573 doing it. 1574 1575 * Doing "cvs commit modules" to checkin the modules file will no 1576 properly run the "mkmodules" program (assuming you have setup your 1577 $CVSROOT/CVSROOT/modules file to do so). 1578 1579 * The -t option in the modules file (which specifies a program to 1580 run when you do a "cvs rtag" operation on a module) now gets the 1581 symbolic tag as the second argument when invoked. 1582 1583 * When the source repository is locked by another user, that user's 1584 login name will be displayed as the holder of the lock. 1585 1586 * Doing "cvs checkout module/file.c" now works even if 1587 module/file.c is in the Attic (has been removed from main-line 1588 development). 1589 1590 * Doing "cvs commit */Makefile" now works as one would expect. 1591 Rather than trying to commit everything recursively, it will now 1592 commit just the files specified. 1593 1594 * The "cvs remove" command is now fully recursive. To schedule a 1595 file for removal, all you have to do is "rm file" and "cvs rm". 1596 With no arguments, "cvs rm" will schedule all files that have been 1597 physically removed for removal from the source repository at the 1598 next "cvs commit". 1599 1600 * The "cvs tag" command now prints "T file" for each file that was 1601 tagged by this invocation and "D file" for each file that had the 1602 tag removed (as with "cvs tag -d"). 1603 1604 * The -a option has been added to "cvs rtag" to force it to clean 1605 up any old, matching tags for files that have been removed (in the 1606 Attic) that may not have been touched by this tag operation. This 1607 can help keep a consistent view with your tag, even if you re-use 1608 it frequently. 1609 1610 Sat Feb 29 16:02:05 1992 Brian Berliner (berliner at sun.com) 1611 1612 * Changes between CVS 1.3 Beta-2 and CVS 1.3 Beta-3 1613 1614 * Many portability fixes, thanks to all the Beta testers! With any 1615 luck, this Beta release will compile correctly on most anything. 1616 Hey, what are we without our dreams. 1617 1618 * CVS finally has support for doing isolated development on a 1619 branch off the current (or previous!) revisions. This is also 1620 extremely nice for generating patches for previously released 1621 software while development is progressing on the next release. 1622 Here's an example of creating a branch to fix a patch with the 2.0 1623 version of the "foo" module, even though we are already well into 1624 the 3.0 release. Do: 1625 1626 % cvs rtag -b -rFOO_2_0 FOO_2_0_Patch foo 1627 % cvs checkout -rFOO_2_0_Patch foo 1628 % cd foo 1629 [[ hack away ]] 1630 % cvs commit 1631 1632 A physical branch will be created in the RCS file only when you 1633 actually commit the change. As such, forking development at some 1634 random point in time is extremely light-weight -- requiring just a 1635 symbolic tag in each file until a commit is done. To fork 1636 development at the currently checked out sources, do: 1637 1638 % cvs tag -b Personal_Hack 1639 % cvs update -rPersonal_Hack 1640 [[ hack away ]] 1641 % cvs commit 1642 1643 Now, if you decide you want the changes made in the Personal_Hack 1644 branch to be merged in with other changes made in the main-line 1645 development, you could do: 1646 1647 % cvs commit # to make Personal_Hack complete 1648 % cvs update -A # to update sources to main-line 1649 % cvs update -jPersonal_Hack # to merge Personal_Hack 1650 1651 to update your checked-out sources, or: 1652 1653 % cvs checkout -jPersonal_Hack module 1654 1655 to checkout a fresh copy. 1656 1657 To support this notion of forked development, CVS reserves 1658 all even-numbered branches for its own use. In addition, CVS 1659 reserves the ".0" and ".1" branches. So, if you intend to do your 1660 own branches by hand with RCS, you should use odd-numbered branches 1661 starting with ".3", as in "1.1.3", "1.1.5", 1.2.9", .... 1662 1663 * The "cvs commit" command now supports a fully functional -r 1664 option, allowing you to commit your changes to a specific numeric 1665 revision or symbolic tag with full consistency checks. Numeric 1666 tags are useful for bringing your sources all up to some revision 1667 level: 1668 1669 % cvs commit -r2.0 1670 1671 For symbolic tags, you can only commit to a tag that references a 1672 branch in the RCS file. One created by "cvs rtag -b" or from 1673 "cvs tag -b" is appropriate (see below). 1674 1675 * Roland Pesch <pesch (a] cygnus.com> and K. Richard Pixley 1676 <rich (a] cygnus.com> were kind enough to contribute two new manual 1677 pages for CVS: cvs(1) and cvs(5). Most of the new CVS 1.3 features 1678 are now documented, with the exception of the new branch support 1679 added to commit/rtag/tag/checkout/update. 1680 1681 * The -j options of checkout/update have been added. The "cvs join" 1682 command has been removed. 1683 1684 With one -j option, CVS will merge the changes made between the 1685 resulting revision and the revision that it is based on (e.g., if 1686 the tag refers to a branch, CVS will merge all changes made in 1687 that branch into your working file). 1688 1689 With two -j options, CVS will merge in the changes between the two 1690 respective revisions. This can be used to "remove" a certain delta 1691 from your working file. E.g., If the file foo.c is based on 1692 revision 1.6 and I want to remove the changes made between 1.3 and 1693 1.5, I might do: 1694 1695 % cvs update -j1.5 -j1.3 foo.c # note the order... 1696 1697 In addition, each -j option can contain on optional date 1698 specification which, when used with branches, can limit the chosen 1699 revision to one within a specific date. An optional date is 1700 specified by adding a colon (:) to the tag, as in: 1701 1702 -jSymbolic_Tag:Date_Specifier 1703 1704 An example might be what "cvs import" tells you to do when you have 1705 just imported sources that have conflicts with local changes: 1706 1707 % cvs checkout -jTAG:yesterday -jTAG module 1708 1709 which tells CVS to merge in the changes made to the branch 1710 specified by TAG in the last 24 hours. If this is not what is 1711 intended, substitute "yesterday" for whatever format of date that 1712 is appropriate, like: 1713 1714 % cvs checkout -jTAG:'1 week ago' -jTAG module 1715 1716 * "cvs diff" now supports the special tags "BASE" and "HEAD". So, 1717 the command: 1718 1719 % cvs diff -u -rBASE -rHEAD 1720 1721 will effectively show the changes made by others (in unidiff 1722 format) that will be merged into your working sources with your 1723 next "cvs update" command. "-rBASE" resolves to the revision that 1724 your working file is based on. "-rHEAD" resolves to the current 1725 head of the branch or trunk that you are working on. 1726 1727 * The -P option of "cvs checkout" now means to Prune empty 1728 directories, as with "update". The default is to not remove empty 1729 directories. However, if you do "checkout" with any -r options, -P 1730 will be implied. I.e., checking out with a tag will cause empty 1731 directories to be pruned automatically. 1732 1733 * The new file INSTALL describes how to install CVS, including 1734 detailed descriptions of interfaces to "configure". 1735 1736 * The example loginfo file in examples/loginfo has been updated to 1737 use the perl script included in contrib/log.pl. The nice thing 1738 about this log program is that it records the revision numbers of 1739 your change in the log message. 1740 1741 Example files for commitinfo and rcsinfo are now included in the 1742 examples directory. 1743 1744 * All "#if defined(__STDC__) && __STDC__ == 1" lines have been 1745 changed to be "#if __STDC__" to fix some problems with the former. 1746 1747 * The lib/regex.[ch] files have been updated to the 1.3 release of 1748 the GNU regex package. 1749 1750 * The ndbm emulation routines included with CVS 1.3 Beta-2 in the 1751 src/ndbm.[ch] files has been moved into the src/myndbm.[ch] files 1752 to avoid any conflict with the system <ndbm.h> header file. If 1753 you had a previous CVS 1.3 Beta release, you will want to "cvs 1754 remove ndbm.[ch]" form your copy of CVS as well. 1755 1756 * "cvs add" and "cvs remove" are a bit more verbose, telling you 1757 what to do to add/remove your file permanently. 1758 1759 * We no longer mess with /dev/tty in "commit" and "add". 1760 1761 * More things are quiet with the -Q option set. 1762 1763 * New src/config.h option: If CVS_BADROOT is set, CVS will not 1764 allow people really logged in as "root" to commit changes. 1765 1766 * "cvs diff" exits with a status of 0 if there were no diffs, 1 if 1767 there were diffs, and 2 if there were errors. 1768 1769 * "cvs -n diff" is now supported so that you can still run diffs 1770 even while in the middle of committing files. 1771 1772 * Handling of the CVS/Entries file is now much more robust. 1773 1774 * The default file ignore list now includes "*.so". 1775 1776 * "cvs import" did not expand '@' in the log message correctly. It 1777 does now. Also, import now uses the ignore file facility 1778 correctly. 1779 1780 Import will now tell you whether there were conflicts that need to 1781 be resolved, and how to resolve them. 1782 1783 * "cvs log" has been changed so that you can "log" things that are 1784 not a part of the current release (in the Attic). 1785 1786 * If you don't change the editor message on commit, CVS now prompts 1787 you with the choice: 1788 1789 !)reuse this message unchanged for remaining dirs 1790 1791 which allows you to tell CVS that you have no intention of changing 1792 the log message for the remainder of the commit. 1793 1794 * It is no longer necessary to have CVSROOT set if you are using 1795 the -H option to get Usage information on the commands. 1796 1797 * Command argument changes: 1798 checkout: -P handling changed as described above. 1799 New -j option (up to 2 can be specified) 1800 for doing rcsmerge kind of things on 1801 checkout. 1802 commit: -r option now supports committing to a 1803 numeric or symbolic tags, with some 1804 restrictions. Full consistency checks will 1805 be done. 1806 Added "-f logfile" option, which tells 1807 commit to glean the log message from the 1808 specified file, rather than invoking the 1809 editor. 1810 rtag: Added -b option to create a branch tag, 1811 useful for creating a patch for a previous 1812 release, or for forking development. 1813 tag: Added -b option to create a branch tag, 1814 useful for creating a patch for a previous 1815 release, or for forking development. 1816 update: New -j option (up to 2 can be specified) 1817 for doing rcsmerge kind of things on 1818 update. 1819 1820 Thu Jan 9 10:51:35 MST 1992 Jeff Polk (polk at BSDI.COM) 1821 1822 * Changes between CVS 1.3 Beta-1 and CVS 1.3 Beta-2 1823 1824 * Thanks to K. Richard Pixley at Cygnus we now have function 1825 prototypes in all the files 1826 1827 * Some small changes to configure for portability. There have 1828 been other portability problems submitted that have not been fixed 1829 (Brian will be working on those). Additionally all __STDC__ 1830 tests have been modified to check __STDC__ against the constant 1 1831 (this is what the Second edition of K&R says must be true). 1832 1833 * Lots of additional error checking for forked processes (run_exec) 1834 (thanks again to K. Richard Pixley) 1835 1836 * Lots of miscellaneous bug fixes - including but certainly not 1837 limited to: 1838 various commit core dumps 1839 various update core dumps 1840 bogus results from status with numeric sticky tags 1841 commitprog used freed memory 1842 Entries file corruption caused by No_Difference 1843 commit to revision broken (now works if branch exists) 1844 ignore file processing broken for * and ! 1845 ignore processing didn't handle memory reasonably 1846 miscellaneous bugs in the recursion processor 1847 file descriptor leak in ParseInfo 1848 CVSROOT.adm->CVSROOT rename bug 1849 lots of lint fixes 1850 1851 * Reformatted all the code in src (with GNU indent) and then 1852 went back and fixed prototypes, etc since indent gets confused. The 1853 rationale is that it is better to do it sooner than later and now 1854 everything is consistent and will hopefully stay that way. 1855 The basic options to indent were: "-bad -bbb -bap -cdb -d0 -bl -bli0 1856 -nce -pcs -cs -cli4 -di1 -nbc -psl -lp -i4 -ip4 -c41" and then 1857 miscellaneous formatting fixes were applied. Note also that the 1858 "-nfc1" or "-nfca" may be appropriate in files where comments have 1859 been carefully formatted (e.g, modules.c). 1860 1861 Sat Dec 14 20:35:22 1991 Brian Berliner (berliner at sun.com) 1862 1863 * Changes between CVS 1.2 and CVS 1.3 Beta are described here. 1864 1865 * Lots of portability work. CVS now uses the GNU "configure" 1866 script to dynamically determine the features provided by your 1867 system. It probably is not foolproof, but it is better than 1868 nothing. Please let me know of any portability problems. Some 1869 file names were changed to fit within 14-characters. 1870 1871 * CVS has a new RCS parser that is much more flexible and 1872 extensible. It should read all known RCS ",v" format files. 1873 1874 * Most of the commands now are fully recursive, rather than just 1875 operating on the current directory alone. This includes "commit", 1876 which makes it real easy to do an "atomic" commit of all the 1877 changes made to a CVS hierarchy of sources. Most of the commands 1878 also correctly handle file names that are in directories other than 1879 ".", including absolute path names. Commands now accept the "-R" 1880 option to force recursion on (though it is always the default now) 1881 and the "-l" option to force recursion off, doing just "." and not 1882 any sub-directories. 1883 1884 * CVS supports many of the features provided with the RCS 5.x 1885 distribution - including the new "-k" keyword expansion options. I 1886 recommend using RCS 5.x (5.6 is the current official RCS version) 1887 and GNU diff 1.15 (or later) distributions with CVS. 1888 1889 * Checking out files with symbolic tags/dates is now "sticky", in 1890 that CVS remembers the tag/date used for each file (and directory) 1891 and will use that tag/date automatically on the next "update" call. 1892 This stickyness also holds for files checked out with the the new 1893 RCS 5.x "-k" options. 1894 1895 * The "cvs diff" command now recognizes all of the rcsdiff 5.x 1896 options. Unidiff format is available by installing the GNU 1897 diff 1.15 distribution. 1898 1899 * The old "CVS.adm" directories created on checkout are now called 1900 "CVS" directories, to look more like "RCS" and "SCCS". Old CVS.adm 1901 directories are automagically converted to CVS directories. The 1902 old "CVSROOT.adm" directory within the source repository is 1903 automagically changed into a "CVSROOT" directory as well. 1904 1905 * Symbolic links in the source repository are fully supported ONLY 1906 if you use RCS 5.6 or later and (of course) your system supports 1907 symlinks. 1908 1909 * A history database has been contributed which maintains the 1910 history of certain CVS operations, as well as providing a wide array 1911 of querying options. 1912 1913 * The "cvs" program has a "-n" option which can be used with the 1914 "update" command to show what would be updated without actually 1915 doing the update, like: "cvs -n update". All usage statements 1916 have been cleaned up and made more verbose. 1917 1918 * The module database parsing has been rewritten. The new format 1919 is compatible with the old format, but with much more 1920 functionality. It allows modules to be created that grab pieces or 1921 whole directories from various different parts of your source 1922 repository. Module-relative specifications are also correctly 1923 recognized now, like "cvs checkout module/file.c". 1924 1925 * A configurable template can be specified such that on a "commit", 1926 certain directories can supply a template that the user must fill 1927 before completing the commit operation. 1928 1929 * A configurable pre-commit checking program can be specified which 1930 will run to verify that a "commit" can happen. This feature can be 1931 used to restrict certain users from changing certain pieces of the 1932 source repository, or denying commits to the entire source 1933 repository. 1934 1935 * The new "cvs export" command is much like "checkout", but 1936 establishes defaults suitable for exporting code to others (expands 1937 out keywords, forces the use of a symbolic tag, and does not create 1938 "CVS" directories within the checked out sources. 1939 1940 * The new "cvs import" command replaces the deprecated "checkin" 1941 shell script and is used to import sources into CVS control. It is 1942 also much faster for the first-time import. Some algorithmic 1943 improvements have also been made to reduce the number of 1944 conflicting files on next-time imports. 1945 1946 * The new "cvs admin" command is basically an interface to the 1947 "rcs" program. (Not yet implemented very well). 1948 1949 * Signal handling (on systems with BSD or POSIX signals) is much 1950 improved. Interrupting CVS now works with a single interrupt! 1951 1952 * CVS now invokes RCS commands by direct fork/exec rather than 1953 calling system(3). This improves performance by removing a call to 1954 the shell to parse the arguments. 1955 1956 * Support for the .cvsignore file has been contributed. CVS will 1957 now show "unknown" files as "? filename" as the result of an "update" 1958 command. The .cvsignore file can be used to add files to the 1959 current list of ignored files so that they won't show up as unknown. 1960 1961 * Command argument changes: 1962 cvs: Added -l to turn off history logging. 1963 Added -n to show what would be done without actually 1964 doing anything. 1965 Added -q/-Q for quiet and really quiet settings. 1966 Added -t to show debugging trace. 1967 add: Added -k to allow RCS 5.x -k options to be specified. 1968 admin: New command; an interface to rcs(1). 1969 checkout: Added -A to reset sticky tags/date/options. 1970 Added -N to not shorten module paths. 1971 Added -R option to force recursion. 1972 Changed -p (prune empty directories) to -P option. 1973 Changed -f option; forcing tags match is now default. 1974 Added -p option to checkout module to standard output. 1975 Added -s option to cat the modules db with status. 1976 Added -d option to checkout in the specified directory. 1977 Added -k option to use RCS 5.x -k support. 1978 commit: Removed -a option; use -l instead. 1979 Removed -f option. 1980 Added -l option to disable recursion. 1981 Added -R option to force recursion. 1982 If no files specified, commit is recursive. 1983 diff: Now recognizes all RCS 5.x rcsdiff options. 1984 Added -l option to disable recursion. 1985 Added -R option to force recursion. 1986 history: New command; displays info about CVS usage. 1987 import: Replaces "checkin" shell script; imports sources 1988 under CVS control. Ignores files on the ignore 1989 list (see -I option or .cvsignore description above). 1990 export: New command; like "checkout", but w/special options 1991 turned on by default to facilitate exporting sources. 1992 join: Added -B option to join from base of the branch; 1993 join now defaults to only joining with the top two 1994 revisions on the branch. 1995 Added -k option for RCS 5.x -k support. 1996 log: Supports all RCS 5.x options. 1997 Added -l option to disable recursion. 1998 Added -R option to force recursion. 1999 patch: Changed -f option; forcing tags match is now default. 2000 Added -c option to force context-style diffs. 2001 Added -u option to support unidiff-style diffs. 2002 Added -V option to support RCS specific-version 2003 keyword expansion formats. 2004 Added -R option to force recursion. 2005 remove: No option changes. It's a bit more verbose. 2006 rtag: Equivalent to the old "cvs tag" command. 2007 No option changes. It's a lot faster for re-tag. 2008 status: New output formats with more information. 2009 Added -l option to disable recursion. 2010 Added -R option to force recursion. 2011 Added -v option to show symbolic tags for files. 2012 tag: Functionality changed to tag checked out files 2013 rather than modules; use "rtag" command to get the 2014 old "cvs tag" behaviour. 2015 update: Added -A to reset sticky tags/date/options. 2016 Changed -p (prune empty directories) to -P option. 2017 Changed -f option; forcing tags match is now default. 2018 Added -p option to checkout module to standard output. 2019 Added -I option to add files to the ignore list. 2020 Added -R option to force recursion. 2021 2022 Major Contributors: 2023 2024 * Jeff Polk <polk (a] bsdi.com> rewrote most of the grody code of CVS 2025 1.2. He made just about everything dynamic (by using malloc), 2026 added a generic hashed list manager, re-wrote the modules database 2027 parsing in a compatible - but extended way, generalized directory 2028 hierarchy recursion for virtually all the commands (including 2029 commit!), generalized the loginfo file to be used for pre-commit 2030 checks and commit templates, wrote a new and flexible RCS parser, 2031 fixed an uncountable number of bugs, and helped in the design of 2032 future CVS features. If there's anything gross left in CVS, it's 2033 probably my fault! 2034 2035 * David G. Grubbs <dgg (a] odi.com> contributed the CVS "history" and 2036 "release" commands. As well as the ever-so-useful "-n" option of 2037 CVS which tells CVS to show what it would do, without actually 2038 doing it. He also contributed support for the .cvsignore file. 2039 2040 * Paul Sander, HaL Computer Systems, Inc. <paul (a] hal.com> wrote and 2041 contributed the code in lib/sighandle.c. I added support for 2042 POSIX, BSD, and non-POSIX/non-BSD systems. 2043 2044 * Free Software Foundation contributed the "configure" script and 2045 other compatibility support in the "lib" directory, which will help 2046 make CVS much more portable. 2047 2048 * Many others have contributed bug reports and enhancement requests. 2049 Some have even submitted actual code which I have not had time yet 2050 to integrate into CVS. Maybe for the next release. 2051 2052 * Thanks to you all! 2053 2054 Wed Feb 6 10:10:58 1991 Brian Berliner (berliner at sun.com) 2055 2056 * Changes from CVS 1.0 Patchlevel 1 to CVS 1.0 Patchlevel 2; also 2057 known as "Changes from CVS 1.1 to CVS 1.2". 2058 2059 * Major new support with this release is the ability to use the 2060 recently-posted RCS 5.5 distribution with CVS 1.2. See below for 2061 other assorted bug-fixes that have been thrown in. 2062 2063 * ChangeLog (new): Added Emacs-style change-log file to CVS 1.2 2064 release. Chronological description of changes between release. 2065 2066 * README: Small fixes to installation instructions. My email 2067 address is now "berliner (a] sun.com". 2068 2069 * src/Makefile: Removed "rcstime.h". Removed "depend" rule. 2070 2071 * src/partime.c: Updated to RCS 5.5 version with hooks for CVS. 2072 * src/maketime.c: Updated to RCS 5.5 version with hooks for CVS. 2073 * src/rcstime.h: Removed from the CVS 1.2 distribution. 2074 Thanks to Paul Eggert <eggert (a] twinsun.com> for these changes. 2075 2076 * src/checkin.csh: Support for RCS 5.5 parsing. 2077 Thanks to Paul Eggert <eggert (a] twinsun.com> for this change. 2078 2079 * src/collect_sets.c (Collect_Sets): Be quieter if "-f" option is 2080 specified. When checking out files on-top-of other files that CVS 2081 doesn't know about, run a diff in the hopes that they are really 2082 the same file before aborting. 2083 2084 * src/commit.c (branch_number): Fix for RCS 5.5 parsing. 2085 Thanks to Paul Eggert <eggert (a] twinsun.com> for this change. 2086 2087 * src/commit.c (do_editor): Bug fix - fprintf missing argument 2088 which sometimes caused core dumps. 2089 2090 * src/modules.c (process_module): Properly NULL-terminate 2091 update_dir[] in all cases. 2092 2093 * src/no_difference.c (No_Difference): The wrong RCS revision was 2094 being registered in certain (strange) cases. 2095 2096 * src/patch.c (get_rcsdate): New algorithm. No need to call 2097 maketime() any longer. 2098 Thanks to Paul Eggert <eggert (a] twinsun.com> for this change. 2099 2100 * src/patchlevel.h: Increased patch level to "2". 2101 2102 * src/subr.c (isdir, islink): Changed to compare stat mode bits 2103 correctly. 2104 2105 * src/tag.c (tag_file): Added support for following symbolic links 2106 that are in the master source repository when tagging. Made tag 2107 somewhat quieter in certain cases. 2108 2109 * src/update.c (update_process_lists): Unlink the user's file if it 2110 was put on the Wlist, meaning that the user's file is not modified 2111 and its RCS file has been removed by someone else. 2112 2113 * src/update.c (update): Support for "cvs update dir" to correctly 2114 just update the argument directory "dir". 2115 2116 * src/cvs.h: Fixes for RCS 5.5 parsing. 2117 * src/version_number.c (Version_Number): Fixes for parsing RCS 5.5 2118 and older RCS-format files. 2119 Thanks to Paul Eggert <eggert (a] twinsun.com> for these changes. 2120 2121 * src/version_number.c (Version_Number): Bug fixes for "-f" option. 2122 Bug fixes for parsing with certain branch numbers. RCS 2123 revision/symbol parsing is much more solid now. 2124 2125 Wed Feb 14 10:01:33 1990 Brian Berliner (berliner at sun.com) 2126 2127 * Changes from CVS 1.0 Patchlevel 0 to CVS 1.0 Patchlevel 1; also 2128 known as "Changes from CVS 1.0 to CVS 1.1". 2129 2130 * src/patch.c (get_rcsdate): Portability fix. Replaced call to 2131 timelocal() with call to maketime(). 2132 2133 Mon Nov 19 23:15:11 1990 Brian Berliner (berliner at prisma.com) 2134 2135 * Sent CVS 1.0 release to comp.sources.unix moderator and FSF. 2136 2137 * Special thanks to Dick Grune <dick (a] cs.vu.nl> for his work on the 2138 1986 version of CVS and making it available to the world. Dick's 2139 version is available on uunet.uu.net in the 2140 comp.sources.unix/volume6/cvs directory. 2141
