It has been a while since commit 8753941, but I think Solaris was such a platform (and maybe AIX, too, based on [1]). [1] http://article.gmane.org/gmane.comp.version-control.git/97076 They could actually just be "grep" in this case, since we know the patterns do not have any metacharacters. I was thinking that our $GIT_COMMITTER_NAME (grepped below) did, but it is "C O Mitter", not "C. O. Mitter".

I added the tag test at the very end, and you can see that it did not get as much attention. :) We should check "! grep mytag stream" here.

So our choices are basically "%m" or "%m %ct". I think the latter is probably the least bad choice. Will switch. There's a potential problem with picking the same branches in the same order. We can cheat a little here, though, because "master" retains its same name. Since there's only one other branch, it's always the other one we want. The trees are not necessarily so lucky. We check that the root tree ends up with a blob and a tree. But the anonymization does not necessarily have to preserve their order (and it probably wouldn't under many schemes).

Yes, because test_commit makes a bunch of extraneous tags, which I thought made the test a little brittle. > > +test_expect_success 'idents are shared' ' > > + git log --all --format="%an <%ae>" >authors && > > + sort -u authors >unique && > > + test_line_count = 1 unique && > > + git log --all --format="%cn <%ce>" >committers && > > + sort -u committers >unique && > > + test_line_count = 1 unique && > > + ! test_cmp authors committers > > +' > > Two commits by the same author must convert to two commits by the > same anonymized author, but that is not tested here; the history > made in 'setup a simple repo' step is a bit too simple to do that > anyway, though ;-). I think we do check that. The commits are all by the same author, so the fact that "sort -u authors" has one line means that they all got anonymized to the same author. What we don't check is that two _different_ authors get different idents. I check that the two idents get different values (authors != committers), but it is not clear from a blackbox test that it is because the anonymization is working (it might be because authors and committers come from a different pool of strings, though I know having written the code that that is not the case). I also do not test that the same ident as an author and as a committer ends up the same. Honestly, I didn't really feel that it was worth much bother. The shape of history and the tree is the most interesting thing here, and the primary thing about idents is that we wipe them. Maybe it was just me being lazy, though. > > +test_expect_success 'commit timestamps are retained' ' > > + git log --all --format="%ct" >timestamps && > > + sort -u timestamps >unique && > > + test_line_count = 4 unique > > +' I think we can drop this one if we check %ct in the graph-shape test above. It's redundant. I'll send v3 in a minute.
