this got me quite a bit further:
git-bisect start git-bisect bad 01363220f5d23ef68276db8974e46a502e43d01d git-bisect good f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38 git-bisect fake-good ee404566f97f9254433399fbbcfa05390c7c55f7 git-bisect bad d43a338e395371733a80ec473b40baac5f74d768 git-bisect bad 255f0385c8e0d6b9005c0e09fffb5bd852f3b506 git-bisect fake-good f99c6bb6e2e9c35bd3dc0b1d0faa28bd6970930d git-bisect fake-good 0187f221e96e3436d552c0c7143f183eb82fb658 git-bisect bad 81450b73dde07f473a4a7208b209b4c8b7251d90 git-bisect fake-good ef29498655b18d2bfd69048e20835d19333981ab git-bisect fake-good 8a03d9a498eaf02c8a118752050a5154852c13bf git-bisect good 5c95d3f5783ab184f64b7848f0a871352c35c3cf git-bisect good ecb5f7521a309cb9c5fc0832b9705cd2a03d7d45 git-bisect good 0539771d7236b425f285652f6f297cc7939c8f9a
81450b73dde07f473a4a7208b209b4c8b7251d90 is first bad commit
[ note: by having the "git-bisect must-have-bugfix f3ccb06f" functionality i mentioned in the previous mail git-bisect could have eliminated the fake-good steps. ]
it's not a resolution of this regression yet, because this commit is a merge with upstream:
| commit 81450b73dde07f473a4a7208b209b4c8b7251d90 | Merge: 8a03d9a... 0539771... | Author: Len Brown <len.brown@intel.com> | Date: Fri Feb 16 18:52:41 2007 -0500 | | Pull misc-for-upstream into release branch
which means that the fix in Len's tree got broken by merging with upstream. Note: this 'upstream' in isolation is broken too, due to not having that essential fix from Len's tree!
So we quite likely have /two/ bugs, any of which breaks resume (which breakage looks the same, so no way to isolate them via testing).
I'll now try the following: i'll try to manually apply Len's fix to every tree that git-bisect offers me, in the hope of being able to isolate the /other/ bug.
[ But really, i'm not expecting any miracles because this is way out of league for git-bisect which really depends on only having a binary space to search for. ]
