Hey,
I wrote a bash script that will retrieve a specified version/tag of a CVS
file without using a sandbox. I added the option of falling back to the
"HEAD" tag when the requested version was not available (by checking to see
if "cvs checkout " was successful (0) or not.)
The problem is that CVS appears to always return 0 when there are no user
tags defined in a CVS file. (This is probably depended on other options as
well ("-p" p" piping file to STDOUT and/or "-kb" using binary mode......
Of course, that's assuming that I'm not just missing some something really
obvious.)
Here is essentially what I tried: (I renamed the tags/files)
cvs checkout -p -kb -r MY_TAG CVS-DIR/my-file > output.file ||
cvs checkout -p -kb -r HEAD CVS-DIR/my-file > output.file
The "CVS-DIR/my-file" did not contain the MY_TAG tag, so the first command
should fail, causing the second command to get the "HEAD" version. But, what
I found is that the first command would exit successfully (without as much
as a warning message, or any of the normal CVS file header information on
STDERR as you would normally get using the "-p" option.), meaning that the
second command would never execute (leaving me with an empty file. And many
hours of confusion...)
Then I added a tag to the CVS file: (from "CVS-DIR/" in my local
sandbox)
cvs tag JUST_A_TAG my-file
At this point I re-ran the "cvs checkout" that I had originally tried. It
worked fine now.
Is this correct behavior, or a bug on in CVS? I just want to make sure this
is NOT how CVS is supposed to work, before I bother the CVS bug/devel
mailing list.
Thanks in advance,
