[cvsnt] CVS with LabView (binary) files

[Martin Cole]

I'm sorry, I was in a hurry, and didn't make a clear email.

There is a module in your repository that is setup by the server called "CVSROOT" if your check this out, you will find it populated with various files, one of them being "cvswrappers"

cvswrappers is a plain text file that tells the server how to operate on specific file types. One of the options in here is the merge method used when you are trying to check in, and someone else has already checked in before you... Obviously if you merge labview vi's, they will fail badly, as it is a propriatory binary format. I added some lines to my cvswrappers file to tell the server to create a copy of the file during update, instead of merge (All standard stuff, not specific to my application).

It may not be perfect, but it works for me, and properly :)

Here is a copy of my cvswrappers file:

# This file affects handling of files based on their names.
#
# The -m option specifies whether CVS attempts to merge files.
#
# The -k option specifies keyword expansion (e.g. -kb for binary).
#
# Format of wrapper file ($CVSROOT/CVSROOT/cvswrappers or .cvswrappers)
#
#  wildcard [option value][option value]...
#
#  where option is one of
#  -m  update methodology value: MERGE or COPY
#  -k  expansion mode  value: b, o, kkv, &c
#
#  and value is a single-quote delimited value.
# For example:
#*.gif -k 'b'


# Wrappers for labview binary files
*.vi -m 'COPY'
*.llb -m 'COPY'
*.llx -m 'COPY'
*.mnu -m 'COPY'
*.ctl -m 'COPY'
*.vit -m 'COPY'
*.rtm -m 'COPY'


# Wrapper for msaccess database files
*.mdb -m 'COPY'
*.mde -m 'COPY'

# End of changes
