[Monotone-devel] Monotone server problems

[Jon Bright]

I've been playing around with setting up a monotone netsync server of my 
own (using the monotone-0.11 deb) and have encountered a few problems:

1. Somebody's mentioned it before on the list, but: empty passphrases. 
Monotone doesn't seem to like them, which makes unattended operation for 
the server a little tricky...

2. Removing keys from the DB doesn't seem to be possible directly - I 
resorted to running the appropriate SQL via the debug command, but this 
doesn't seem optimal.  Additionally, when importing a key with an ID 
that's already in the database, the old key is left alone (probably 
correctly) but no warning is printed to the effect that there's already 
a key by that name...

3. On the server, I took the following steps:

a) monotone --db=... db init
b) monotone --db=... genkey address@hidden
c) monotone --db=... --branch=com.sc.project cvs_import /path/to/repo
d) <key importing/exporting stuff>, <setup of permissions to allow my 
client key to pull*>
e) monotone --db=... --rcfile=permissions.lua serve 
host.siliconcircus.com com.siliconcircus.project

* side note - the docs don't surround the addresses with quotes, but 
this wouldn't work for me until I'd added quotes...

On the client:
a) monotone --db=... db init
b) monotone --db=... genkey address@hidden
c) <key importing/exporting stuff, synchronised with stage d on the 
server side>
d) monotone --db=... pull host.siliconcircus.com com.siliconcircus.project

This went ok (albeit with a lot of debug output), until:

-----------------------------
processing 411096 byte input buffer from peer host.siliconcircus.com
netio.hh:31: invariant 'I(pos < str.size())' violated
db.execute("ROLLBACK")

*** Error: std::logic_error: netio.hh:31: invariant 'I(pos < 
str.size())' violated


**** error return code 205
-----------------------------

e) Ran the same command again (without changing anything, so using the 
same db), got:

-----------------------------
monotone: read from fd 5 (peer host.siliconcircus.com) closed OK after 
goodbye
-----------------------------

f) monotone --branch=com.siliconcircus.project checkout project-source

This produced:

-----------------------------
monotone: fetching heads of branch 'com.siliconcircus.project'
monotone: misuse: no file version 
faa94569b127838245641b4025add6ccb97c6cea found in database for .cvsignore
-----------------------------

After this, I was left with directory 'project-source', which contained 
the MT directory, which in turn contained a manifest, which contained 
hashes for all files in the project.

4. The CVS import should import files within the Attic directories in an 
already-deleted state.  But you probably know this already, and it's not 
a big deal...
