[darcs-devel] [Fwd: [issue67] Getting a tag giving inconsistent repository.]

[Grant Husbands]

Hi,

It was mentioned to me that I might want to CC the list on this, so 
below's a bug that you may be interested in, as it results in a broken 
repository. It turned out to be less significant than we thought and no 
longer significantly impedes our use of Darcs.

We've had some success in tracing this issue. It looks like darcs get 
--tag doesn't store the commuted patches. We don't know how to fix it. 
Here's a simple way to reproduce the bug:

$ mkdir repo1
$ cd repo1
[repo1]$ darcs init
[repo1]$ cat >file
1
2
3
4
[repo1]$ darcs add file
[repo1]$ darcs record -a -m 'Added file'
Darcs needs to know what name (conventionally an email address) to use 
as the
(...)

What is your email address? edwint
Finished recording patch 'Added file'
[repo1]$ cat >file
2
3
4
[repo1]$ darcs record -a -m 'Removed line 1'
Finished recording patch 'Removed line 1'
[repo1]$ cat >file
2
4
[repo1]$ darcs record -a -m 'Removed line 3'
Finished recording patch 'Removed line 3'
[repo1]$ cd ..
$ mkdir repo2
$ cd repo2
[repo2]$ darcs init
[repo2]$ darcs pull C:/darcsbug/repo1
