See the Cederqvist manual (cvs.texinfo) for information on how to report bugs (and what will happen to your bug reports if you do). The following is a list of some of the known bugs. It may or may not be comprehensive. We would dearly love for people to volunteer to help us keep it up to date (for starters, if you notice any inaccuracies, please let bug-cvs know as described in the Cederqvist manual). There are some other reported bugs in MINOR-BUGS; the difference, at least in theory, is that those bugs are less serious. * For platform-specific information (in some cases including known bugs), see README.VMS, windows-NT/README, or os2/README. There is no similar file for the unix-like operating systems (not yet, at least). This file also might contain some platform-specific bugs. * If your login name contains a space or various other characters (particularly an issue on Windows), CVS will have trouble (it will write invalid RCS files, probably). The fix would be to have CVS change such characters to underscores before writing them to the RCS file. Furthermore, the LOGNAME or USER environment variables usually won't override the system login name, so this can be hard to work around. * If you specify the -w global option to client/server CVS, it only overrides a CVSREAD environment variable set on the client, not a CVSREAD variable which was set on the server (for example, in .bashrc when the server was run via rsh). The fix of course will be to provide a "Option-read-write" request which sends -w, in addition to "Global_option -r" which sends -r. * Symbolic links to files will not work with or without LockDir. In the repository, you should avoid using symbolic links to files since this issue can cause data loss. Symlinks are only a problem when writing files. If your repository does not allow any write access, symlinks are not a problem. * Symbolic links to directories will not work with LockDir. In the repository, you should avoid using symbolic links to directories if you intend to use LockDir as the correct directory will NOT be locked by CVS during write. Directory symlinks are not recommended, but should work as long as LockDir is not being used. Symlinks are only a problem when writing files. If your repository does not allow any write access, symlinks are never a problem, whether or not LockDir is in use. * The -m option to "cvs add" does not work with client/server CVS. CVS will accept the option, but it won't actually set the file's description. * cvs update walks into a user's work directory if there's a directory of the same name in the repository even if the user's directory doesn't yet have a CVS admin sub-directory. This can greatly confuse users who try to add the same directory at nearly the same time. * From: "Charles M. Hannum" To: Subject: Still one more bug Date: Sat, 25 Feb 1995 17:01:15 -0500 mycroft@duality [1]; cd /usr/src/lib/libc mycroft@duality [1]; cvs diff -C2 '-D1 day ago' -Dnow cvs server: Diffing . cvs server: Diffing DB cvs [server aborted]: could not chdir to DB: No such file or directory mycroft@duality [1]; `DB' is an old directory, which no longer has files in it, and is removed automatically when I use the `-P' option to checkout. This error doesn't occur when run locally. P.S. Is anyone working on fixing these bugs? * CVS does not always seem to be waiting to the next filesystem timestamp quanta after commits. So far this has only shown up in testing under the BSDI OS. The symptoms are that ocassionally CVS will not notice that modified files are modified, though the file must be modified within a short time after the commit, probably milliseconds or seconds, for this symptom to be noticed. One suspected cause is that one of the calls to sleep_past() is being called with an incorrect value, though this does not explain why symptoms have only been noticed under BSDI. * The CVS server is leaving a temp directory (/tmp/cvs-serv*) on AIX 4.3 under very rare circumstances (one out of c. 10,500 test cases). This appears to be dependent on some sort of race condition as it disappears with tracing enabled and under the debugger. Informative feedback is welcome. * UNICOS 9.0 on Cray currently fails testing in both client/server and writeproxy modes. * Status This experimental version of CVS contains new features which may not have been tested as thoroughly as the stable release. It is classified as: /*-------------. | Experimental | `-------------*/ /*-------------------------. | Sane for full scale use. | `-------------------------*/
