      CMFActivity: in case of ConflictError, retry earlier than for other failures · 30fbdd3d
      Julien Muchembled authored 
      This tweaks retry delays as follows (seconds):

        ConflictError  other failures (K = 1 + retry², with retry >= 0)
before     30             15 * K
after      15             30 * K

Today, bigger delays in case of errors should not be an issue because the
quality of ERP5 has improved a lot and normal code should not rely anymore on
this.

We also don't want to lower ConflictError delay too much, because this
increase the probability of conflicts.

This will be required to improve invokeGroup, in case that a message fails.
We'd like that:
- successful messages are retried immediately
- skipped messages are retried next, and separately
- at last, failed messages are retried, also separately

      CMFActivity: automatic migration of queues and removal of button to recreate tables · 3d644bde
      Julien Muchembled authored 
      The action to recreate activity tables while preserving existing messages
was unsafe for 2 reasons:
- if any error happened, messages could be lost
- it relied on Message.reactivate

Which this patch, any instance created after commit d881edd1 (Aug 2010) will
upgrade successfully. For older instances, make sure you have no activity left.

For cases where 'ALTER TABLE' would not work, a better way to implement repair
functionality would be:
- one action to backup all messages in ZODB
- and another to restore them
And maybe a security so that during the backup-clear-restore sequence,
activities can't be created nor processed.

If any column is added in the future, it would still be possible to write code
that fills them by inspecting messages.

      Commit work done by Vincent · e2ff442c
      Sebastien Robin authored 
        Make ActivityTool:Message.getObjectList simple to use: detect internaly 
wether an expand method must be called, catch exception when object on which 
the activity was executed cannot be found.
  Remove broadcast message support.
  Merge indexes on processing_node and processing columns on both message and 
message_queue tables.
  Always use SQL server's time.
  Do not update processing node value when setting the message as being 
processed.
  Commit SQL connection as soon as messages get assigned to reduce lock 
duration.
  Make SQLDict ZSQLMethods support list of uids instead of single value per 
call.
  Make ZSQLMethod handle processing_node differently if it's 0 or None (when 
not passed as parameter, behave as if it's None).
  Do not force all parameters to be passed to SQLQueue_setPriority.
  Factorise SQL code inside <dtml-if> blocks.
  Allow to select ranges of lines in readMessageList with a custom offset.
  When reseting message processing state at first activity execution pass 
after a node start, also reset the processing_node.
  Commit SQL connection as soon as messages are set to processing state, 
mainly to make it visible outside current connection.
  Add a common class for SQL-using activity queues.
  CMFActivity/Activity/SQLDict.py
    Remove unused (and broken) prepareQueueMessage method.
    Replace a tab by spaces.
    Add ZSQLMethod wrappers for new ZSQLMethods.
    Split dequeueMessage into dequeueMessage, getProcessableMessageList, 
finalizeMessage_Execution.
    Return True instead of 0 in case of an important error, in order to 
prevent CMFActivity from doing infinite loops  over dequeueMessage when 
something goes wrong.
  CMFActivity/Activity/Queue.py
    Allow caller to specify the current date and transmit it when recursing. 
Fallback on DateTime (calculate just once) if not specified.
  CMFActivity/Activity/SQLQueue.py
    Precompute parameters in prepareQueueMessage to make it easier to add a 
log when needed. Also reduces the distance with SQLDict's equivalent method.
    Add ZSQLMethod wrappers for new ZSQLMethods.
    Split dequeueMessage into dequeueMessage, getProcessableMessageList, 
finalizeMessage_Execution.
    Return True instead of 0 in case of an important error, in order to 
prevent CMFActivity from doing infinite loops  over dequeueMessage when 
something goes wrong.
  Add scripts to monitor activity distribution.  
  Remove unused ZSQLMethods.
  Add new ZSQLMethods related to the new distribution scheme and SQL server 
time grabbing.

      This big change optimizes the scheduling of active objects, · 1c300e5c
      Yoshinori Okuji authored 
      and fix some bugs.

The basic idea is to track a dependency graph to find executable
messages quickly. This makes the activity system far more efficient,
when you have many inter-dependent messages queued in the tables.

Also, this obsoletes the time shifting in the schedulers,
as executable messages can be found in a more efficient manner.
So the activity parameter "at_date" should work expectedly.

Now the API of validate methods in Activities return a
list of message objects instead of a boolean value. Such
a list contains messages that are depended upon by a given
message.

The validate method in Message accepts a new optional
parameter, check_order_validation, to indicate whether
order validation should be performed. The default behavior
has not changed.

getDependentMessageList is added to ActivityTool, Queue
and Message. This method collects dependent message for
a given message from all activities.

There are some other subtle changes. Look at the diffs for
more details.
