This release contains bugfixes as well as a new playhouse extension module for
working with SQLite in multi-threaded / concurrent environments.
The new module is called playhouse.sqliteq and it works by serializing
queries using a dedicated worker thread (or greenlet). The performance is quite
good, hopefully this proves useful to someone besides myself! You can learn
more by reading the sqliteq documentation.
As a miscellaneous note, I did some major refactoring and cleanup in
ExtQueryResultsWrapper and it's corollary in the speedups module. The code
is much easier to read than before.
Bugs fixed
- #1061 - @akrs patched a bug in
TimestampFieldwhich affected the accuracy
of sub-second timestamps (for resolution > 1). - #1071, small python 3 fix.
- #1072, allow
DeferredRelationto be used multiple times if there are
multiple references to a given deferred model. - #1073, fixed regression in the speedups module that caused SQL functions to
always coerce return values, regardless of thecoerceflag. - #1083, another Python 3 issue - this time regarding the use of
exc.message.
