[Monotone-devel] monotone.cvssync: Invariant failure

[Tobias Hunger]

Hi there!

I managed to build the monotone.cvssync branch on ubuntu/breezy (gcc 4.0) 
without problems. All 239 tests in the testsuite behaved as expected. 
Congratulations on that!

What I wanted to do was import the gdb sources into monotone. So I set up a DB 
first, using the usual commands:
    > monotone --db=~/.MT/gdb.db db init
    > monotone --db=~/.MT/gdb.db genkey email-as-above

Then I tried to import the CVS module:
    > monotone --db=~/.MT/gdb.db \
         address@hidden/gdb-dejagnu \  
         -k "email-as-above" \
         cvs_pull :pserver:address@hidden:/cvs/src gdb+dejagnu

    enter passphrase for key ID [email-as-above]:
    monotone: bytes in | bytes out
    monotone:     6692 |       517 |        0

Running the cvs_pull with debug gives the following information for the 
critical passage:

    [snip]
    monotone: readline result 'T9999'
    monotone: readline result 'Set-sticky src/cpu/'
    monotone: readline result '/cvs/src/src/cpu/'
    monotone: readline result 'T9999'
    monotone: readline result 'E cvs checkout: warning: new-born

    monotone: warning: cvs checkout: warning: new-born src/djunpack.bat has 
disappeared
    monotone: readline result 'Remove-entry src/'
    monotone: readline result '/cvs/src/src/djunpack.bat'
    monotone: cvs_client::RequestServerDir lresult[0].second is 
'Remove-entry', not 'Clear-static-directory'
    monotone: cvs_client.cc:1467: invariant 
'I(lresult[0].second=="Clear-static-directory")' violated
    monotone: db.execute("ROLLBACK")
    [snip]

I hope this helps with debugging. The really good thing is that it fails very 
early, so this is not causing too much network traffic when testing it;-)
