Re: Eclipse, cvs, and extssh

[Mark D. Baushke]

Hi Bruno,

After doing a bit more research, I agree that Joseph P. Skudlarek's
patch was not applied as originally posted.

Sudlarek's patch introduces CVS_SSH to handle cases where "ssh" is not
good enough.

Derek's original reply:
  http://www.mail-archive.com/bug-cvs@nongnu.org/msg00638.html

Indicates that he intended for :extssh: as an alias for :ext: rather
than adding functionality to ignore CVS_RSH and use $CVS_SSH or "ssh".
After all, the default is --with-rsh=ssh for cvs 1.11.22 already.

As for cvs 1.11.22, you are quite correct. It is missing a few changes
to work properly. The first, in client.c to use RSH_DFLT instead of "rsh"
as a hardcoded value. The configure step will hopefully have defaulted
RSH_DFLT to "ssh" if it is available. The second file is root.c which
needs to do the right thing when it processes the :extssh: method.

I have a source patch for the client.c and root.c files to hopefully
fix your problem.

I plan to commit these patches along with some changes to sanity.sh
to verify that :extssh: works as soon as my regression tests pass.

I plan to commit these patches to both the cvs 1.11.xx STABLE
(cvs1-11-x-branch) and cvs 1.12.xx FEATURE (main trunk) branches this
week.
