The problem is that _DB_get_type() can't be called without the GIL
because it calls a bunch of PyErr_* APIs when an error occurs.
There were no other cases in this file that it was called without the GIL.
Removing the BEGIN/END THREAD around _DB_get_type() made everything work.
Will backport.
now works reliably. It has been updated to use automatic BerkeleyDB
deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
database calls that would previously deadlock. [SF python bug #775414]
aborts the db transaction safely when a modifier callback fails.
Fixes SF python patch/bug #1408584.
Also cleans up the bsddb.dbtables docstrings since thats the only
documentation that exists for that unadvertised module. (people
really should really just use sqlite3)
in BerkeleyDB >= 4.2 it tried to construct a list out of an uninitialized
char **log_list.
feature: export the DB_ARCH_REMOVE flag by name in the module on BerkeleyDB >= 4.2.
bsddb.*open() methods cachesize parameter wouldn't work (raised an
internal bsddb.db exception when it was given). The set_cachesize
call needed to be moved from the DB object to the DBEnv since the env
was introduced to allow for threading.
(will backport to 2.4)
Using None for a filename with the 'n' flag when calling bsddb.btopen
would cause an error while checking if the file None existed. error
not likely to be seen as anyone using None for a filename would likely
use the 'c' flag in the first place.
between a TestCase instance, the database it opened (or a cursor to a
database) and a bound method as a registered database callback, and a lack
of GC-handling in bsddb caused the TestCases to linger. Fix the test, for
now, as backward compatibility makes adding GC to bsddb annoying.
* the has_key() method was not raising a DBError when a database error
had occurred. [SF patch id 1212590]
* added a wrapper for the DBEnv.set_lg_regionmax method [SF patch id 1212590]
* DBKeyEmptyError now derives from KeyError just like DBNotFoundError.
* internally everywhere DB_NOTFOUND was checked for has been updated
to also check for DB_KEYEMPTY. This fixes the semantics of a couple
operations on recno and queue databases to be more intuitive and results
in less unexpected DBKeyEmptyError exceptions being raised.
