version 1.1.0 (tag zasync-1_1_0)

(note that there is a spurious zasync_1_1_0 tag as well)

• Add Windows files and rc files from Arno Gross into bin directory.
• Put more information on diagnostic call analysis page, thanks to Arno Gross.
• Make zasync work in 2.7 and 2.8. Note that making it run in 2.7 now requires an extra argument to run: see the example files in the bin directory. Briefly, here are two example calls, from one of my test installations:

  For 2.7:

  ~/zope2/bin/python -c "import zasync; zasync.run(/home/gary/zope2/instance277/etc/zasync.conf, 2.7)"

  For 2.8:

  ~/zope2/bin/python -c "import zasync; zasync.run(/home/gary/zope2/instance/etc/zasync.conf)"

• Add some example text about the zope_exec plugin in plugins.txt.

version 1.0.7 (tag zasync-1_0_7)

• Some small changes (like using get_transaction().begin()) driven more by superstition and risk reduction than anything else.
• Make manager include lines that make Python datetime objects acceptable to use in restricted python. This should make it easier for a simple install.
• Fix edge-case bug: if you have a call manager with new calls that have expired, the client would not be working with wrapped deferred objects so aq_... attributes would be missing and the new call wouldn't be tossed, and new (non-expired) calls wouldn't be processed.

version 1.0.6 (tag zasync-1_0_6)

• More fixes for the code path of handling error-raising reprs (grr).

version 1.0.5 (tag zasync-1_0_5)

• cleanFailure using customized code because __repr__ can fail in Zope. :-/
• Fix nasty small bug in client.py that could make zasync effectively into a zombie process. :-(

version 1.0.4 (tag zasync-1_0_4)

• Add in ability to pass in form variables to request.
• Fix bug in rendering error message in client config.

version 1.0.3 (tag zasync-1_0_3)

• fix retry code in client to call makeCall correctly

version 1.0.2 (tag zasync-1_0_2)

• Try for more and earlier transaction aborts.
• Reinstate lost diagnostic call analysis page.

version 1.0.1 (tag zasync-1_0_1)

• Added new diagnostic call analysis page for the ZMI call manager. Unfortunately it was not exposed in this release. :-/
• Attempt to improve the README file to give people more of a chance to get this set up and going.
• A clean up of the two example configuration scripts to remove references to Zope 3, which really probably just confused matters.
• Manager needs to fix up local roles to get the owner info in.

version 1.0 (tag zasync-1_0)

• Add an overview tab that includes information on the plugins and allows you to ping the zasync client to see if it is active.
• Make the verbose traceback optional, defaulting to False. Incorporate the new verbose traceback option in logging output
• Make the normal Zope event log work.
• Go ahead and include temporary storage in schema and example zasync.conf so DBTab doesn't complain.
• Add new "aggregate" plugin.
• Include exception info in Conflict Error logs.
• Make a returned failure in a zope exec callback abort the transaction.
• Bug fixes in plugins, especially zope_exec
• fix bug: if tool disappeared, then zasync was unable to recover because of a number of problems. Most importantly, it was holding on to connections without closing them. Fixed this bug and similar problems elsewhere.
• More paranoid about starting up now, and more paranoid about telling the manager about the available plugins when the tool has been re-found.
• tweak backoff interval for assigning tasks; add backoff interval to calling zope_exec start_worker so that existing threads have a better chance to grab new jobs before we create an unnecessary new thread.
• Add sanitize method so that calls to (and from zope_exec) do not have persistent objects.
• Remove an opportunity for Conflict Error in the client.
• Don't raise an error when a deferred is called twice--this will abort the transaction, which means that the deferred will never be resolved if it was supposed to be. Therefore, return a failure and log the problem.
• Add a here to the context dict for the callbacks because some code wants it.

version 0.2

• Significantly rewritten to solve the problems of 0.1.
  • don't keep persistent objects around
  • try to handle exceptions better
  • close the connection after every transaction
• remove all CMF dependencies of the call manager
• Use a ZConfig-based configuration for zasync
  • better Zope initialization
  • configuration-driven plugin registration
• saner startup
  • not reliant on zopectl run (intended to be in preparation for using twistd)
  • sh start script
• try to remove plugins from the manager's plugin list upon zasync shutdown
• ZPL
