Yesterday, a few of our developers started seeing an “abort:
00manifest.i@60300915ca73: unknown parent!” error when running `hg
pull` (Mercurial 3.8.4 on Windows 7 x74). I tracked the problem to a
specific changeset, stripped it from our central repository, and they
were able to pull again.
Last week, our Mercurial server died mid-transaction. It is very large
(over 9GB with 175k changesets). The only way to recover was to
re-clone the repository, omitting the last 9,000 commits. After the
clone, I then pushed the “missing” 9,000 changesets from an
uncorrupted clone.
All changesets pushed fine except for two. When I push them, I get
“abort: 00manifest.i@8ed639f6a6e0: no node!” and “abort:
00manifest.i@60300915ca73: no node!” errors.(This second one is the
same missing changeset from above). Wjhen I tried to strip these two
changesets from my repository, I get the “abort:
00manifest.i@60300915ca73: no node!” error. I have no idea of the
missing parent/node errors are related to the corruption and clean-up
process.
From the repository corruption page, it seems like my only option is
to re-clone my repository, excluding these two changesets, then pull
in the remaining changesets from an uncorrupted repository. Since our
repository takes hours to re-clone, I’m wondering if there are any
other magic tricks for stripping these two changesets from my repository.
There is some magic, you can actually truncate revlog files (because
they are append-only) to get rid of the highest rev numbers.
If you do this to just the changelog.d and changelog.i files, then I
think hg recover knows how to fix up the rest of the files in your repo.
You will lose bookmarks pointing to any changesets that you remove as
well when the bookmarks file is next written.
