test-convert: demonstrate an unstable hash issue for bzr -> hg -> hg It looks like the manifest value changing is the only difference, but I'm not sure why it's happening. I've got a similar divergence in a production repo that was also converted from bzr and has an octopus merge[1]. Unlike here, the manifest values for the destination merge commits reflect the initial merge only, instead of all four merges agreeing like this test. $ hg -R src_repo manifest -r 310 --debug | grep file # octopus fixup merge 2d8775bc2481bd28ac87038ecdf33e1dbddc80e9 644 file1 6adb9353a55bb8be76e71382efc724ec3ccf7ed5 644 file2 $ hg -R src_repo manifest -r 309 --debug | grep file # first merge 362e7cb5163153c4989daad1a834871ae849f205 644 file1 2c65d947191938c3ea616b7ceb7648ff3843261f 644 file2 $ hg -R dst_repo manifest -r 273 --debug | grep file # octopus fixup merge 362e7cb5163153c4989daad1a834871ae849f205 644 file1 2c65d947191938c3ea616b7ceb7648ff3843261f 644 file2 $ hg -R dst_repo manifest -r 272 --debug | grep file # first merge 362e7cb5163153c4989daad1a834871ae849f205 644 file1 2c65d947191938c3ea616b7ceb7648ff3843261f 644 file2 This divergence is espcially annoying because unlike changelog differences, I haven't figured out a way to fix this in code. The only way I found to work around it is to convert up to the point of divergence, `hg bundle` the bad revision in the source, apply it to the destination, add a line to the shamap, and fire off the conversion again. But I suspect that there's more to it than just the octopus merge because I also have a commit in the same repo, done in Mercurial (well after the conversion) that is exhibiting a similar issue (and it's not a merge commit). I'm almost positive that it was created with 4.4 or later. Any ideas? [1] https://www.mercurial-scm.org/pipermail/mercurial/2018-June/050924.html
