In ERP5 software release we now have `mock` egg installed, so we can use it in tests instead of doing manually like this:

```python
saved_method = Class.method
def patched_method():
  ...
try:
   Class.method = patched_method
   ...
finally:
   Class.method = saved_method
```

Change the caching policy to one hour.

Use the CDN to publish the page if the backend is down

Cache the manifest like the HTML page but force refreshing the manifest to prevent CDN cache inconsistency.

Defining it inside portal_components ledds to business template update issue.
Bypass it by defining the expected behaviour into the web section hook.

Allow the CDN to cache the content.

Use stale_if_error to allow the CDN to return content if backend is down

Unify Vary Header.

erp5_banking_cash depends from erp5_trade via erp5_banking_core.

Gadgets:

* Support `changed` flag from `erp5.js`: 

![unsaved changes sreenshot](/uploads/cff30eae0a5d87df26bac13d43e1da3f/image.png)

* Comply with translation protocol used in ERP5JS. This does not translate, because it would not be easy ( ERP5JS translate client side with a json database of message, but in xhtml style the translation is performed server side with localizer) and not so important now. What matters is just that we can somehow reuse gadgets.

Style:

* While we are at it, fix a minor annoyance that the button in "long" dialogs where not easy to reach, at least on chrome

Remove all globals to allow multiple live tests running on the same page.
Stop reading the test output if the browser tab doesn't have the focus.
Stop hardcoding the URL in the javascript.
Stop hardcoding other fields path in the javascript (+ embed the textarea in the gadget).

Propagate all parameters via formulator.
It will allow to use this gadget from another context document.

Run live test from the RJS UI

This way we can use gadgets using of ERP5JS translation API in xhtml
style.
This is really minimal compatibility layer and translation is not
actually performed.

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

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.

This way the "you have unsaved changes" pops up also when navigating
away after changing gadget content.

When the page height is larger than viewport, the scrollbar hides the
button on chrome.  Also does the "Loading" status message on chrome.
By using a margin, we make sure buttons are not behind scrollbar or
status message and are easier to reach.

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.

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.
