>Description:
When "cvs export" is used to export the same file, two or more times in a
row, using a remote repository only (not a local repository), the command
fails with the error:
cvs export: cannot open CVS/Entries for reading: No such file or directory
cvs [export aborted]: no repository
This is not a serious problem, but it makes me wonder if something more
serious might be broken. Since this is an export command, the
local CVS/Entries (or _any_ local CVS files) should not be accessed at all.
Why is the Entries file being accessed? Why only when using a remote
repository? The problem does not occur when the reposittory is local.
>How-To-Repeat:
1) Export a file from cvs, SPECIFICALLY specifying a remote
user and repository. NOTE: I am using ssh v1.2.26 for CVS_RSH
> cvs -d cvsuser@cvshost:/my_cvs_home export -D now my_cvs_module
U my_cvs_module
This works fine. The file is sucessfully exported from CVS.
2) Now try the same command again:
> cvs -d cvsuser@cvshost:/my_cvs_home export -D now my_cvs_module
cvs export: cannot open CVS/Entries for reading: No such file or directory
cvs [export aborted]: no repository
This time the command fails. For some reason, cvs is attempting
to access CVS/Entries, but this should not be happening for an export.
NOTES:
1) This failure only occurs when "user@repository" is specified,
even if the repository is on the local machine. This failure
does not occur if the repository is specified as simply a path
on the local machine.
2) This is happening with cvs clients 1.10.6 & 1.10.8 for Linux.
Also 1.10.5 for FreeBSD. I haven't tested any other
versions/platforms.
3) I haven't tested with rsh as opposed to ssh.
4) Here is a trace with more useful info:
> cvs -t -d cvsuser@cvshost:/my_cvs_home export -D now my_cvs_module
cvs export: notice: main loop with CVSROOT=cvsuser@cvshost:/my_cvs_home
-> Starting server: ssh cvshost -l cvsuser cvs server
S-> do_module (my_cvs_module, Updating, , )
cvs export: cannot open CVS/Entries for reading: No such file or directory
cvs [export aborted]: no repository
>Fix:
well, don't export the same file twice. aside from that, I don't know
