This commit replaces calls to pycompat helpers that were intended for
python 2 <-> python 3 interoperability for python 3 builtins, as python
2 is no longer officially supported by Odoo.
This includes:
* calls to imap/izip/ifilter replaced by map/zip/filter
* uses of text_type replaced by str
* uses of unichr replaced by chr
* calls to implements_to_string, implements_iterator removed
* string_types and integer_types replaced by str, int respectively
* calls to to_native replaced by calls to to_text
This is done in preparation to the removal of these deprecated helpers
in the following commit.
After 12744bc81ebdaa1671a953c14ba54c637d6a9255, x2m operations are
fully batched, and deletions are processed last when the operations are
flushed, regardless of the order in which they were specified by the
write() or create() call.
This carries a risk of violating (non-deferred) unique SQL constraints,
when the operations for deleting previous lines and re-creating new
ones are processed in the same batch.
This patch executes the deletions before other operations during a
flush, which should be safer with regard to SQL constraints.
An extra constraint is added in test_performance.line to simulate this
corner case, then covered by an extra unit test.
Another unrelated test had to be altered to avoid violating the
new constraint.
This can be reproduced easily by upgrading the `project` module in master,
due to the unique constraint[1] on `ir.actions.act_window.view`, that
gets violated when processing the batch write on this o2m[2].

Purpose of this commit is to give description more "business oriented"
because those descriptions appears in Odoo Studio which is supposed to be used by end users, not only by developers.

When a record fields are prefetched, the currently accessed record is
prefetched as well as PREFETCH_MAX (=1000) minus currenly accessed
records.
Since 439fa826 the id field was thought as "prefetched" but was not,
which caused that in an onchange, we would have a prefetching as follow
for 1200 records:
- get records 1-1000
- get record 1001 (1001-1200 INTERSECTION 1-999 (id) + 1001 (current))
- get record 1002 (1002-1200 INTERSECTION 1-999 (id) + 1002 (current))
- get record 1003 (1003-1200 INTERSECTION 1-999 (id) + 1003 (current))
- ...
- get record 1200 (1200 INTERSECTION 1-999 (id) + 1200 (current))
So we would do 201 queries instead of 2 when prefetching the records.
The added test without this change failed the query count with:
"AssertionError: 284 not less than or equal to 5 : admin"

closes#24326
Add the context manager method `assertQueryCount` to count queries,
the decorator `@users(...)` to execute a test for several users, and
the decorator `@warmup` to execute a test twice (warm-up, then real).
Containing
* fix self._round not always existing;
* fix counter for activity creation;
* use self.str() in order to have some variation in test_mail;
* separate base performance to mail feature specific performance tests;
Test performance will now hold the base class for performance tests as
well as tests related to the ORM, depending only on base. A new module
test_mail is introduced at this commit that contains performance tests
related to mail module. This commit contains only code move and should
not impact anything.
Future commits will move mail tests into test_mail so that all mail
related tests are located in the same optional module. This allows
notably to avoid creating a lot of unnecessary tables when installing
mail module on production databases.
The command does not need to remove existing relations, as there is no relation
yet on new records. This saves one query per many2many field with that command
in a `create`.
An update by a list of commands is now guaranteed to have at most three SQL
queries to update the relation, whatever the number of commands and records.
The record cache is indexed by `(field, record_id, key)`, where `key` depends
on the environment. The key is either `(cr, uid, context)` or `(cr, uid)`,
depending on whether the field's value is context-dependent. As most fields
are not context-dependent, this should avoid some cache prefetching when
swiching context.
