SHA1KnitCorrupt

[Luca Pireddu]

I tried upgrading a shared repository in rich-root-pack format
$ bzr info
Shared repository with trees (format: rich-root-pack)
Location:
  shared repository: .

The upgrade fails.

 SHA1KnitCorrupt: Knit <bzrlib.knit._VFContentMapGenerator object at 0xb613f8c> corrupt: sha-1 of reconstructed text does not match expected sha-1. key ('<email address hidden>',) expected sha 57d965dfb10bbf76f8f955f430ba6eb251c1621a actual sha 87e3fcef65c712c69ab77c9b2ab9144ec9956e65

I've attached a complete crash log. I suppose there's a corrupt tree in the shared repository, but the error doesn't say anything, nor does it suggest how I may restore the repository (I figured out that moving the backup to .bzr should fix it).

I can retrieve all the history from the (restored) trees, so I don't think they're corrupt. If it helps, some of them are checkouts of svn repository. Some of the trees report "Repository tree (format: unnamed)", if "unnamed" means anything to you.

I'll be happy to provide more information if necessary.

Crash log attached.

Can you try to run 'bzr check -v' and then 'bzr reconcile' and report the results ?

On bzr check -v (crash file attached)

$ bzr reconcile
Reconciling repository file:///home/pireddu/Projects/old_migrepo_to_trash/
Reconciliation complete.
$ bzr check -v

Again, as before. By the way, the crash happens after

   Checking repository at 'file:///home/pireddu/Projects/old_migrepo_to_trash/'.

i.e. while it's checking the shared root, after it has checked all the individual branches.
