Hi all, I am a bit surprised by the behavior of "darcs get --tag" and I wonder if I'm misinterpreting the following statement in the output of "darcs get --help":
It is often desiderable to make a copy of a repository that excludes some patches. For example, if releases are tagged then `darcs get --tag .' would make a copy of the repository as at the latest release. Does "as at the latest release" actually means "as at the latest *tagged* release" or effectively "as at the latest *commit*"? My case is as follows: I have a product on a server, in production, where I forgot to properly tag the exact version; I made some further changes in my development branch and when I realized the fact, I went on the production server and made a tag there, that I subsequently pulled in my development branch: as expected, doing a "darcs changes" shows the tag, at the top of all my other changes I recorded. At this point I wanted to test the exact production version and thus I tried to "darcs get --tag X" from my *development* branch, but what I got was actually a copy of the whole development branch, *including* the changes that are *not* part of the X tag! I tried with both latest darcs (2.8.1) and a previous version (2.5.2) with the same result, so the doubt about me doing something wrong... I'm pretty sure I already did something like that in the past, and it worked! I'm attaching a test script that exhibits the unexpected behaviour.
