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

a modified version from nexedi/erp5$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.

Draft: The first state when we create a new Sale Opportunity.

Open: All information of the Sale Opportunity is entered such as prospect's contact email, questions, etc

Suspended: We replied to prospect, waiting for their return.

Closed: The Sale opportunity is either 1) accepted by prospect, turn into a Sale Order; or 2) Clearly rejected by prospect.

Expired: No return/ news from prospect for some time.

Deleted: in case added by mistake, so user can delete it

Reference must always be after the web section path.

This will also forbid using document relative url directly (web_page_module/123).

See merge request nexedi/erp5!1666

For example, Web Section can contain a Script (Python) to set Access
Rule, but the parent section's objectValues(portal_type='Web Section')
should not include such object.

When there are many simultaneously-pending activities attached to any
processing node family, the
  node>=0
subquery becomes dominant (taking hundreds of time longer than the other
subqueries). As a consequence, this starves processing nodes of activities
and increases the CPU needs of the mariadb process hosting the activity
tables.
So, move this subquery out of the regular codepath, and only run it if no
other subquery found any activity:
- there is no activity preferentially targeting the current node
- there is no activity bound to any of the current node's families
- there is no activity without any node preference at all
Also, simplify the content of that subquery: the effective priority can
only be 3 * priority + 1 when this query is run, and node=0 rows can be
excluded (they should not exist in the current database view).
Also, factorise the logic producing "node=processing_node" and
"node IN node_set" subqueries, for simplicity. In turn, this makes all
family-dependent subqueries use a simple equality test, ensuring a stable
query plan independently from the number of families the current node is
member of.
Also, use "UNION ALL" always, as now:
- all subqueries have stritly distinct result sets
- as per mariadb documentation, "UNION [DISTINCT] applies to all UNIONs
  on the left", so the original comment about where ALL is used was
  incorrect in assuming it was improving the effective query performance
Also, line-split SQL queries as visible in the python source to be more
readable, without effect on the produced SQL.
Also, line-split a few non-trivial python expression to make their
internal structure immediately apparent.

Another effect of this change this change is to reduce activity theft
(activities to be preferentially executed by one node being executed by
another), potentially improving object cache hit-rate and hence decreasing
I/O pressure on the ZODB.

this way they will be expanded in simulation
