Re: Error when creating tags from working copy

[Michael Susser <hd...@googlemail.com>]

Hi David,

this can't be true, because it worked with all versions until 1.5.2. "Tag
from working copy" would make no sense if all files must have the same
revision...

Re: Error when creating tags from working copy

It looks like you're right. My understanding is that there are four
different types of copies in Subversion:

WC -> WC
URL -> WC
WC -> URL
URL -> URL

And, that when you do a copy to a URL, no actual copying happens. Instead, a
simple link is made from one URL and version to another.

That would mean that a working copy having multiple revisions in it wouldn't
pick up all those revisions since only a single URL and version are linked..

However, I just did a quick test. In a test repository, I checked out a
project, then updated one file to a previous revision. This way, the whole
directory has multiple revisions in it. Then I did:

$ svn cp . http://subversion/dev/foo/tags/TEST

I then executed:

$ svn log -v http://subversion/dev/foo/tags/TEST

Changed paths:
   A /foo/tags/TEST (from /foo/trunk:46988)
   R /foo/tags/TEST/build.xml (from /foo/trunk/build.xml:20137)

Testing
[...]

So, Subversion actually did pick up the different revisions in side my
working directory when it created the tag.

I assume the same thing happens if I had a different revision in a directory
than a file. However, I am using Subversion 1.3 as a client.
