[Monotone-devel] Sanity check failures on current head

[Jon Bright]

Hi,

This seems like a blocker for 0.17.  Upon following the self-hosting 
instructions on venge.net, using current head, the pull fails a sanity 
check.  I've run it with --debug, the last few lines of the debug log are:

monotone: db.fetch("SELECT id FROM 'manifest_deltas' WHERE id = 
'be30a61e6943059d907bc3dfa2780ad1f47aa95d'")
monotone: db.fetch("SELECT id FROM 'manifests' WHERE id = 
'be30a61e6943059d907bc3dfa2780ad1f47aa95d'")
monotone: db.fetch("SELECT base from 'manifest_deltas' WHERE id = 
'be30a61e6943059d907bc3dfa2780ad1f47aa95d'")

monotone: version cache expiring 57e868c942e01cac463a2a902b65591e330b7660
monotone: db.fetch("SELECT data FROM revisions WHERE id =

violated
monotone: db.execute("ROLLBACK")

The full log's 112MB, but a 7.6MB bzip2ed version of it can be found at 
http://discord.ensued.net/pulllog.bz2

Following this, I copied a 0.16 DB, did 'db dump' with 0.16, did 'db 
load' with 0.17, did 'db migrate' with 0.17.  This resulted in a db with 
which I could check out the monotone source.  On trying 'db rebuild', 
however, a different sanity failure occurred.  I've run this with 
--debug, too, but I can't really tell how much of the end of the debug 
log might be needed.  The assertion, in any event, is:

monotone: finished concatenation
monotone: revision.cc:158: invariant 'I(*changesets.find(old_id)->second 
== *old_to_child_changes_p)' violated

More of this is available to any takers, too :-)  The whole thing's 
73MB, but again, a 2MB bzip2ed version of it can be found at
http://discord.ensued.net/rebuildlog.bz2

All of this was on Win32, but Derek describes similar symptoms.
