This file contains the current CVS root, as described in Specifying a repository.

This file contains the directory within the repository which the current directory corresponds with. It can be either an absolute pathname or a relative pathname; CVS has had the ability to read either format since at least version 1.3 or so. The relative pathname is relative to the root, and is the more sensible approach, but the absolute pathname is quite common and implementations should accept either. For example, after the command

cvs -d :local:/usr/local/cvsroot checkout yoyodyne/tc

`Root' will contain

:local:/usr/local/cvsroot

and `Repository' will contain either

/usr/local/cvsroot/yoyodyne/tc

or

yoyodyne/tc

This file lists the files and directories in the working directory. It is a text file according to the conventions appropriate for the operating system in question. The first character of each line indicates what sort of line it is. If the character is unrecognized, programs reading the file should silently skip that line, to allow for future expansion.

If the first character is `/', then the format is:

/name/revision/timestamp[+conflict]/options/tagdate

where `[' and `]' are not part of the entry, but instead indicate that the `+' and conflict marker are optional. name is the name of the file within the directory. revision is the revision that the file in the working derives from, or `0' for an added file, or `-' followed by a revision for a removed file. timestamp is the timestamp of the file at the time that CVS created it; if the timestamp differs with the actual modification time of the file it means the file has been modified. It is in Universal Time (UT), stored in the format used by the ISO C asctime() function (for example, `Sun Apr 7 01:29:26 1996'). One may write a string which is not in that format, for example, `Result of merge', to indicate that the file should always be considered to be modified. This is not a special case; to see whether a file is modified a program should take the timestamp of the file and simply do a string compare with timestamp. conflict indicates that there was a conflict; if it is the same as the actual modification time of the file it means that the user has obviously not resolved the conflict. options contains sticky options (for example `-kb' for a binary file). tagdate contains `T' followed by a tag name, or `D' for a date, followed by a sticky tag or date. Note that if timestamp contains a pair of timestamps separated by a space, rather than a single timestamp, you are dealing with a version of CVS earlier than CVS 1.5 (not documented here).

If the first character of a line in `Entries' is `D', then it indicates a subdirectory. `D' on a line all by itself indicates that the program which wrote the `Entries' file does record subdirectories (therefore, if there is such a line and no other lines beginning with `D', one knows there are no subdirectories). Otherwise, the line looks like:

D/name/filler1/filler2/filler3/filler4

where name is the name of the subdirectory, and all the filler fields should be silently ignored, for future expansion. Programs which modify Entries files should preserve these fields.

This file does not record any information beyond that in `Entries', but it does provide a way to update the information without having to rewrite the entire `Entries' file, including the ability to preserve the information even if the program writing `Entries' and `Entries.Log' abruptly aborts. Programs which are reading the `Entries' file should also check for `Entries.Log'. If the latter exists, they should read `Entries' and then apply the changes mentioned in `Entries.Log'. After applying the changes, the recommended practice is to rewrite `Entries' and then delete `Entries.Log'. The format of a line in `Entries.Log' is a single character command followed by a space followed by a line in the format specified for a line in `Entries'. The single character command is `A' to indicate that the entry is being added, `R' to indicate that the entry is being removed, or any other character to indicate that the entire line in `Entries.Log' should be silently ignored (for future expansion). If the second character of the line in `Entries.Log' is not a space, then it was written by an older version of CVS (not documented here).

This is a temporary file. Recommended usage is to write a new entries file to `Entries.Backup', and then to rename it (atomically, where possible) to `Entries'.

The only relevant thing about this file is whether it exists or not. If it exists, then it means that only part of a directory was gotten and CVS will not create additional files in that directory. To clear it, use the update command with the `-d' option, which will get the additional files and remove `Entries.Static'.

This file contains per-directory sticky tags or dates. The first character is `T' for a branch tag, `N' for a non-branch tag, or `D' for a date, or another character to mean the file should be silently ignored, for future expansion. This character is followed by the tag or date. Note that per-directory sticky tags or dates are used for things like applying to files which are newly added; they might not be the same as the sticky tags or dates on individual files. For general information on sticky tags and dates, see Sticky tags.

These files store the programs specified by the `-i' and `-u' options in the modules file, respectively.

This file stores notifications (for example, for edit or unedit) which have not yet been sent to the server. Its format is not yet documented here.

This file is to `Notify' as `Entries.Backup' is to `Entries'. That is, to write `Notify', first write the new contents to `Notify.tmp' and then (atomically where possible), rename it to `Notify'.

If watches are in use, then an edit command stores the original copy of the file in the `Base' directory. This allows the unedit command to operate even if it is unable to communicate with the server.

The file lists the revision for each of the files in the `Base' directory. The format is:

Bname/rev/expansion

where expansion should be ignored, to allow for future expansion.

This file is to `Baserev' as `Entries.Backup' is to `Entries'. That is, to write `Baserev', first write the new contents to `Baserev.tmp' and then (atomically where possible), rename it to `Baserev'.

This file contains the template specified by the `rcsinfo' file (see rcsinfo). It is only used by the client; the non-client/server CVS consults `rcsinfo' directly.
