This is created temporarily while an RFL/RFL lock is created. > RFL/WFL lock - created on every read (the rfl file) and write > the wfl file? > Seems to be in the lockdirs only directory.

They're created during checkout, update, log, and other read-only operations, and deleted when the operations complete. WFL files are exclusive (write) locks, and are created by commit, tag, rtag, and other write operations, and are deleted when the operations complete. The locking algorithms are described in great detail in the CVS documentation. They get left behind when something extraordinary happens that causes CVS to terminate early (e.g. kill -9, broken pipes in *info scripts, and so on). > ,file, - every time file is updated in the repository, this > file is created in the directory the ,v file resides > in. Destroyed (actually copied over ,v) at end of > write operation. These are RCS lock files. Whenever the version history of a file is modified (e.g. commit, tag, admin -k, and so on), a copy of the ,v file is made which is used as a lock. The copy (the ,*, file) is written with the necessary changes, and then renamed back to the its original (,v) name when it's complete. Again, these are left around only when something extraordinary happens. >Any help you folks can provide is greatly appreciated. >--- End of forwarded message from [EMAIL PROTECTED] _______________________________________________ Info-cvs mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/info-cvs
