It seems to accept int, but version is supposed to be a string.

See merge request !1671

a modified version from $366
that supports patterns like
DateTime(2001, 02, 03) => DateTime(2001, 2, 3)
and not DateTime(2001, 0o2, 0o3)

Javascript does not support big integers, so the backend have to be
careful not to return too large numbers in the json. Nowadays there
is bigint, but not equivalent for decimal numbers, so the backend
tries to detect if numbers are too big and returns them as string
in that case - which is better than returning a different number
because it displays correctly in the result table. The pivot table
will still wrong, but at least the table of results is OK.

use sax.xml API which gives us the first parser available, instead of
using a specific parser that happens to come from pyxml

serialize as json instead of using xml.marshal.generic which was
provided by PyXML

This allows custom movement generators to set ad-hoc properties on
generated movements depending on properties of the corresponding
input movement.

There was already _getUpdatePropertyDict which is similar, but was
sometimes not enough because it can only be use to set extra
properties on all movements.

As a result, when we needed a rule with custom properties on
generated movements, we resorted to overriding getGeneratedMovementList
and duplicating the full logic of the method. Existing cases have
been updated to use the new _updateGeneratedMovementList and in the
case of InventoryAssetPriceAccountingRuleMovementGenerator we no
longer need to duplicate the logic.

Also remove the comment suggesting overriding getGeneratedMovementList
in subclasses, now several "extension" methods exists, so it should
not be needed to override getGeneratedMovementList, every needs
should be coverred by defining _updateGeneratedMovementList or
_getUpdatePropertyDict

This patch does not seem necessary

This SELECT option was added when the UPDATE query was split into a
SELECT + UPDATE query pair, in order to try to avoid deadlocks in mariadb.

      Work around poor UPDATE use of index.
That was not completely successful, and another attempt was since made,
which further ipmproved the situation:

      CMFActivity.Activity.SQLBase: Reduce the number of deadlocks

This change made the "FOR UPDATE" option obsolete: there should be
virtually no parallelism between the SELECT and UPDATE queries.
By which I mean only 3rd-party accesses (like an admin on a mysql console)
would bypass the SQL lock, causing index-update-level locking issues.

Checking now, I see that removing "FOR UPDATE" on the "node>0" query makes
that query (with LIMIT 30) run about 5 times faster:
With FOR UPDATE:    0.509s
Without FOR UPDATE: 0.090s
This difference is enough to cause significant activity starvation on a
63-processing-nodes cluster where such activities run in about 1s, just
because of the amount of contention on the SQL lock, itself because of the
duration of every execution of this query.

So remove this now-redundant option.

It is expected that this will improve activity processing performance in
general, beyond just the starvation issue which led to this discovery.
