Subject: Invitation to test cothread.catools release candidate

At http://controls.diamond.ac.uk/downloads/python/cothread in the git repository listed there I have pushed updates for both the current version of cothread (to shortly be released as version 2.6) and a Python 3 branch.

I would be very grateful if anybody interested in using cothread.catools could check out the latest version from git and test this pre-release in your environment.  I've also posted links on the cothread page to downloads for this pre-release version.


cothread.catools is a Python library providing easy to use and powerful Channel Access bindings.

Since version 2.3, released in January, there have been a number of significant changes, including:

1. Support for Python 3.  Please apply the 2to3 patch or check out the Python 3 branch.

2. Explicit support for Unicode in Python 2 (and correspondingly for bytes in Python 3) as a requested data type in caput or camonitor, and as a value in caput.

3. The default camonitor events mask now takes account of the requested format, so for example, alarm updates are reported if appropriate.

4. Channel access is now allowed to run asynchronously to improve the handling of rapidly updating data streams. 

5. Fix long standing OSX compatibility bug.

6. Fix equally long standing bug in EPICS epoch correction.

7. FORMAT_TIME values now have a .datetime property.


Of these changes points 4, 5 & 6 are probably the most significant.  The channel access change hugely improves performance when processing large images.
