Hmph. I happened to be looking at the write_idx_file code a few minutes ago, and noticed the results of commit 68be2fe (receive-pack, fetch-pack: reject bogus pack that records objects twice, 2011-11-16). Now I feel like a dunce for reimplementing the same thing a few lines above (and the reason I did not catch it in my tests is that "index-pack --strict" is not enabled by default). We should probably drop the two top commits. We may want to keep the test from the second-to-last, though, but change it to use "index-pack --strict". Like this: -- >8 -- Subject: t5308: check that index-pack --strict detects duplicate objects Commit 68be2fe long ago taught index-pack to notice and reject duplicate objects if --strict is given (which it is for incoming packs, if transfer.fsckObjects is set). However, it never tested the code, because we did not have an easy way of generating such a bogus pack. Now that we have test infrastructure to handle this, let's confirm that it works.
