This is a preliminary commit that only adds a verbatim copy of WSGIPublisher.py

ERP5TypeTestCase: replace ZPublisher.Test.publish_module with ZPublisher.Publish.publish_module_standard

Sorting in a module is terrible for performance as soon as there is more
than a trivial amount of documents in that module.

Test was failing because family mapping is loaded while connection is
already closed.

Load the object explicitly before so that it's in cache.

SlapOS and NMS documentation are moved into bt and committed in erp5-doc.git. This will allow to install documentation in another erp5 and also to test them.

3 independent conditions does not guarantee to find the next row sorted
simultaneously on those 3 values.

listActions result is cached, and may refer to non-existing workflows
and/or worklists. Tolerate either of these being missing.

It was failing due to addition of module actions in the menu panel.
The test was checking the content of the menu panel before the page was fully loaded,
so getting the old menu panel entries and failing.

- Hardcodes a panel "VIEWS: List" to hide "consistency", "history" and "metadata".
- Only show "WORKFLOWS" on module document.

For instance, on Foo Module the menu panel shows now :

    VIEWS
      List
    ACTIONS
      Do Something

[erp5_accounting_ui_test] Update check_row_in_transactions_table and check_row_in_accounts_ledger_table macros in AccountingZuite_reportMacros to follow the bugfix 17c0aa5a.

But renderjs listbox still creates unneeded broken links and this problem is reproduced in test_journal although it is not tested yet.

If event has an aggregate relation already, merge it with the
aggregate relation of notification message.

When a cell value was empty, listbox js created a link that did not work.

The pagination was not working when using the limit parameter, and when
the total number of documents is equal to the pagination limit + 1.

Before:
   Float Equivalence Tester does not test the divergence even if Divergence Provider is ON
    
After:
     Float Equivalence Tester test the divergence with the epsilon-span if Divergence Provider is ON
    
Before, we needed the following condition to test the divergence at Float Equivalence Tester:
    
       "Divergence Provider is ON"  AND
       ("Absolute Tolerance has some value"  OR
        "Relative Tolerance has some value" )
    
However this default behavior was not consistent with other testers, and
difficult to notice from the user interface.
Thus test the divergence by default with the epsilon span which is defined in 
FloatEquivalenceTester class.
    
The epsilon-span is the same amount that when we put 0.0 into the ranges.
The 0.0 has been the configuration of erp5_configurator_standard_trade_template.

When an object is being indexed, it get wrapped so it has magic properties,
like security definitions as they will be accessed by indexation methods.
One such property is used to trigger the insertion of rows in
roles_and_users table. That property has the special feature that it is
only produced on the first object needing a new set of rows added to
roles_and_users, other objects will get a None value instead for that
property so that no further lines are inserted.
Then, SQCatalog iterates over that wrapper list to compute all indexation
method parameters. It does so via a cache (LazyIndexationParameterList) so
that unused parameters are not computed. The cache key is wrapped object's
uid.
All this together means that if an object is indexed multiple times in a
single call (which happens at site creation, for example) and it needs a
new set of rows added in roles_and_users, only one of produced wrappers
will get the appropriate value. If that object is not the first on which
that parameter is evaluated (which gets more likely with every copy of the
same object being indexed), it will be cached as None and shared between
all copies, causing no row to be added to roles_and_users.

For example, if property_sheet "prop" was moved from BT 1 to BT 2 and BT 1 doesn't exist anymore.

Before this commit we have this order:
1.  install BT 2 ("prop" exist and isn't touched)
2. remove BT 1 ("prop" is removed)
=> at the end "prop" doesn't exist anymore

After this commit we have this order:
1. remove BT 1 ("prop" is removed)
2. install BT 2 ("prop" is readded)
=> at the end "prop" exists and is OK

old key was simply "id" so when a container is a VirtualFolder (like Web
Site), container._getOb("id") can return any object with id "id"
including an object outside the container.
    
Change the key to contain PhysicalPath of the container to get only
objects inside the container.
    
This actually fixes installation of some business templates with Web
Site inside.

Not all lock uses in this code fit context managers, but use them where it
does.

Add 10 seconds timeouts on all blocking calls in this test method, which
should be a thousand times more than required on a slow machine but avoids
completely blocking tests.

Even though it should not raise, a stale lock would be a serious issue.
