Migration partially fails without visible diagnostics on Unicode errors

Reported by: checat@… Owned by: John Hampton

Cc: Trac Release: 0.11


Migration fails for my installation of trac with additional

First of all, there were no diagnostics on console!

Output was:

$ python sqlite2pg -e env -p 'postgres://www:@/trac'
Timing and Estimation needs an upgrade
Upgrading Database
Creating bill_date table
Creating report_version table
Upgrading report_version table to v4
Dropping report_version table
Upgrading reports
Upgrading usermanual
Done Upgrading

But in reality (in pg_log) there are messages:

ERROR:  relation "bill_date" does not exist
ERROR:  relation "report_version"  does not exist

This situation must be detected at least.

In result only some part of tickets was migrated.

I've found the reason of failure. It's unrelated to mentioned log entries and output.

One of tickets appears to contain non-UTF-8 data whcih cannot be decoded by pysqlite2 adapter.

>>> from pysqlite2 import dbapi2 as sqlite
>>> conn = sqlite.connect('./trac.db')
>>> c = conn.cursor()
>>> c.execute('select * from ticket')
<pysqlite2.dbapi2.Cursor object at 0xb7f131a0>
>>> for row in c :
...   pass
pysqlite2.dbapi2.OperationalError: Could not decode to UTF-8 column 'description' with text ' ........

But the ticket still applies. Trac itself complains accessing this ticket, but sqlite2pg doesn't, silently failing in 'for' operator, but it should complain.
