The way addToDate was working with dates was not good, and creating
confusion when removing 1 month from the last days of a 31-day month, as
the previous day had less days than the current month:

date = DateTime(2023, 5, 31)
print date
print addToDate(date, month=-1)
> 2023/05/31 00:00:00 GMT+2
> 2023/05/01 00:00:00 GMT+2

This was even more confusing in March, with february having only 28
days:

date = DateTime(2023, 3, 31)
print date
print addToDate(date, month=-1)
> 2023/03/31 00:00:00 GMT+2
> 2023/03/03 00:00:00 GMT+2

The new behavior is to, when removing a month, if the new day of the new
month is more than the number of days in month to default to the last
day of the month. For exemple, removing one month from 31/05 becomes
30/04, and from there it will add/remove the days as necessary.

The real issue being that removing a month is ambiguous and can mean
a different thing for different people.

For reference, the reference implementation of timedelta in python
doesn't support adding months:

https://docs.python.org/3/library/datetime.html#datetime.timedelta

I hope my solution will make the more sense in ERP5's context.

The fix from 7597c300 (accounting_l10n_fr: don't export
lines with 0 quantity in FEC, 2023-03-31) was not 100% correct,
lines with a quantity but with an asset price of 0 were still
exported.

We used a wrong condition that was causing lines with a debit
and asset credit (ie. different sides) to be output wrongly
with debit and credit.

in 5ae0508d (accounting_l10n_fr: Workaround encoding bugs
in Test Compta Demat, 2023-03-31) we replaced a few characters
that were known to be problematic, but while trying on some
other production data, we found new problematic characters.
This shown that this approach was too "optimistic" and that we
the safest way to have a file that is compatible with Test
Compta Demat is to use only ascii characters, this use
unicodedata to try to retain the original characters (so that
"Jérôme" becomes "Jerome") and also special case € to replace
it by "EUR"

    If two open orders are validated on the same transaction, archivePrevious script will get the an already archived as catalog will be outdated.

we pass the schema already, but for now this only supports basic
syntax highlighting

programmatically calling script.setParameterSignature('') was
setting _params to None and making it causing errors when calling
the script

This change modifies the FEC export to conform to the test software from
https://www.economie.gouv.fr/dgfip/outil-test-des-fichiers-des-ecritures-comptables-fec 
/ https://github.com/DGFiP/Test-Compta-Demat.

A new `test_compta_demat_compatibility` to enable compatibility mode was introduced.
This will be True when rendering the report from the dialog, i.e., using `AccountingTransactionModule_viewFrenchAccountingTransactionFile` and False when
using `AccountingTransactionModule_viewFrenchAccountingTransactionFileActive` directly
so the behavior of reusing FEC export for accounting interfaces should be the same as before.

XLTE(*) follows the same top-level packaging structure like
wendelin.core does.

Registration is done via new `register_xpkg` function instead of just
loop so that pkgname argument is properly captured in created lambda and
does not change after going to next iteration.

In 5796a17a (core_test: Add test to make sure that wendelin.core
basically works) I added wendelin_transform to pylint so that the
checker could recognize wendelin.core's special wendelin top-level
module/package and handle ok

	from wendelin.bigarray.array_zodb import ZBigArray

this works, but e.g. for plain

	import wendelin			or
	from wendelin import bigarray

pylint currenly fails with

	AssertionError: explicit relative import, but no context_file?

To better see what is going on let's conside the following test program

	"""ZZZ"""

	from wendelin.bigarray.array_zodb import ZBigArray
	from wendelin import bigarray

	def main():
	    """main"""
	    _ = ZBigArray

and run pylint on it. Here is what it gives:

we see that the line

	from wendelin.bigarray.array_zodb import ZBigArray

corresponds to

	('_add_imported_module', <From() l.3 [test] at 0x7ff214b4cb90>, 'wendelin.bigarray.array_zodb.ZBigArray')

and the line

	from wendelin import bigarray

corresponds to

	('_add_imported_module', <From() l.4 [test] at 0x7ff214b4cf50>, '.bigarray')

notice that in the latter case there is no 'wendelin' prefix and the
import goes as just '.bigarray' instead of 'wendelin.bigarray' which
leads to further crash in get_module_part.

-> Fix it by initializing wendelin module yielded by wendelin_transform
with .name set. Not sure why it is working longer imports without that.

  On the automatic upgrade some bt5 (erp5_core) can be upgraded
  before erp5_property_sheets. Since, it isnt a problem if this happens
  if no Mixin configuration is present, it is better directly check the
  existence of the property on the bt5.

  In general we expect that erp5_property_sheets is upgraded before any
  other bt5 with TypeMixin definition.

       Use the proper way to include Mixin into a portal type

   Use the proper way to include Mixin into a portal type

  This value isnt exported anymore

 Handle type_mixin like property_sheets and use Business Template properly

  Allow the developer associate a Mixin on Business template level
without require to overwrite the portal type itself

  Include mixins can be done in the same way, allowed content types or
property sheets are set.

After updating Products.CMFCore we had issues on sites where URLTool was registered as ISiteRoot.

In the case of ERP5, we don't really need portal_url.getPortalObject(), this changes to use ERP5Site.getPortalObject(), while at the same time doing something so that portal_url.getPortalObject() also works.

See https://github.com/zopefoundation/Products.CMFCore/pull/126 for more details

this is a "magic" local variable used to add more debugging information
in zope traceback, it's not supposed to be used directly so it was a
false positive in our case.

This extends the default value of --dummy-variable-rgx that was defined
to _$|dummy in pylint 1.4.4 (
https://github.com/PyCQA/pylint/blob/pylint-1.4.4/pylint/checkers/variables.py#L296

Products.CMFCore's version 2.7.0 of portal_url.getPortalObject
returns the portal in an incomplete acquisition context, which
causes issues when the site is registered as ISiteRoot utility
(the typical error being AttributeError REQUEST)

ERP5Site.getPortalObject works just fine and is used in many
places, this commit replaces all occurences of
portal_url.getPortalObject by getPortalObject.
