R devel - Feb 2002 - File permissions test during R CMD check

I (still) use RCS, and not CVS, for my own projects. R CMD check does not
like the 0444 file permissions on files check into RCS.  

I conjecture that this stems from desire to have the installed files in a
state in which they can be edited, but I might be off base ... In case my
conjecture holds, would it be possible to relax the restriction during R CMD
check, but then install the files as 0644 ?

Other than that, R CMD check is a very impressive tool.

Not as long as R CMD build takes what is in the source dirs.

There are some comments about possible improvements to permission tests
in the code of check, but in any case all files that are to be installed
should be at least 644.  We could relax that for e.g. C source or
headers, but not e.g. for DESCRIPTION.

Dirk, I've had the exaxt same situation months ago (since then
R-devel was "1.4.0 to be") and reacted the same way as you, just
to R-core instead of R-devel back then ....
My solution was to manually "rcs -U" all the relevant files, and
from then on, rcs kept them rw-r--r-- (aka 644) as desired.
I haven't seen a reason why I should use RCS locks when I'm the
only one accessing these files.

(yes, and because of that and later submission to CRAN
 I agree that "--no-perms" is not a solution to me neither).

I think that I understand why R CMD check should warn if the permissions on a
file are too restrictive, but I don't understand why it should warn if they
are
"too" loose. On UNIX, why is a file with 644 OK, but one with 664
(just adding
group writability) problematic enough to require a warning?

Thanks,
