Is advisory file locking an option? Such as the "portalocker" module for Python?
You can have your writer process obtain an exclusive lock (and block
until it's obtained), while the readers obtain shared locks for the
duration of their read.
Readers don't block other readers, while writers block
Bob,
Is there are reason you can't use PyODBC?
https://github.com/mkleehammer/pyodbc/wiki
It is more actively maintained and I've used it successfully for years.
I'm curious what adodbapi is doing for you that PyODBC can't? Are you using
non-SQL data sources?
thanks,

You could have a worker thread or process that keeps the serial port open
and listens for jobs on some kind of task queue.
However it's not clear to me how keeping the serial port open between
requests provides assurance of data integrity.

Without getting into too philosophical of a discussion, the only sense
in which objects can truly move from one process to another is
recreating them in the other process. Even fork() makes copies of

Hi,
I think people might be reluctant to give you an in-depth tutorial

Hello all,
I'm curious why the odbc module included in PyWin32 (version 214) is
compiled without the Unicode flags/defines. This prevents you from
using Unicode string literals in queries. By that I mean the Unicode
literals are converted to the 8-bit codepage (cp1252) and any
