fast-export: don't handle uninteresting refs They have been marked as UNINTERESTING for a reason, lets respect that. Currently the first ref is handled properly, but not the rest. Assuming that all the refs point at the same commit in the following example: % git fast-export master ^uninteresting ^foo ^bar reset refs/heads/bar from :0 reset refs/heads/foo from :0 reset refs/heads/uninteresting from :0 % git fast-export ^uninteresting ^foo ^bar master reset refs/heads/master from :0 reset refs/heads/bar from :0 reset refs/heads/foo from :0 Clearly this is wrong; the negative refs should be ignored. After this patch: % git fast-export ^uninteresting ^foo ^bar master # nothing % git fast-export master ^uninteresting ^foo ^bar # nothing And even more, it would only happen if the ref is pointing to exactly the same commit, but not otherwise: % git fast-export ^next next reset refs/heads/next from :0 % git fast-export ^next next^{commit} # nothing % git fast-export ^next next~0 # nothing % git fast-export ^next next~1 # nothing % git fast-export ^next next~2 # nothing The reason this happens is that before traversing the commits, fast-export checks if any of the refs point to the same object, and any duplicated ref gets added to a list in order to issue 'reset' commands after the traversing. Unfortunately, it's not even checking if the commit is flagged as UNINTERESTING. The fix of course, is to check it. However, in order to do it properly we need to get the UNINTERESTING flag from the command line, not from the commit object, because "^foo bar" will mark the commit 'bar' uninteresting if foo and bar points at the same commit. rev_cmdline_info, which was introduced exactly to handle this situation, contains all the information we need for get_tags_and_duplicates(), plus the ref flag. This way the rest of the positive refs will remain untouched; it's only the negative ones that change in behavior.
