RCS 5.7 & bin/text mounts

RCS 5.7 & bin/text mounts

[Ian Miller]

Hi, I'd like some advice on how I can make best use of the RCS 5.7 port
for Cygwin B20. The README file says:-

     - the package has been built for binary mounts and not tested on
       nonbinary ones. But as RCS internally handles its files in UN*X
       LF format I don't expect it to work.

However, I have all my partitions mounted as text!=binary as recommended by
various posters and FAQs. I used to use the DJGPP port of RCS in conjunction
with NTEmacs 20.x and had no problems; but now if I check stuff in and out
using NTEmacs and my old RCS files, I get corrupted RCS files, though it
seems to work perfectly with newly created RCS files!

[I believe NTEmacs adopts the "approved" Cygwin approach of removing the 
CR's for display and replacing them when the file is written (even though
it is not itself a Cygwin port)? ]

I don't understand why there should be a problem with using this port of
RCS with text mounts, because surely it just means that extra characters
are checked in and out (i.e. the CR's)? I presume the DJGPP port did something
different re: the CR/LF situation, and that is why I am having trouble 
checking in/out old files? Please advise!

cheers,
ian

Ok, a little more experimentation reveals that all is not well even with
new RCS files - although the latest version is checked out by NTEmacs in
text-mode, previous versions are displayed as "Unix" (i.e. binary mode),
and diffs as a result seem to go a bit funny...

What is the best solution to this problem - simply to mount the partition
that I do my RCS work on, as binary? I still don't understand why RCS is
interfering with the extra CR's added by text-mode anyway... if that is
indeed the problem...?

cheers,
ian

You're right about the exrta CR's: if the RCS file foo.c,v is stored in
"UNIX mode" (no extra CR's) and you check foo.c in "DOS mode", the extra
CR's _will_ count as differences, even if you haven't changed a single char.

I rebuilt RCS on a text mounted filesystem, and so far, it seems to work OK. I
haven't stressed it very much, though.
