The registry attributes 'registry_invalidated' and 'cache_invalidated'
are used to flag that the current request has modified the registry or
invalidated the ormcache, respectively. This provides a simple yet
efficient way to signal registry changes or cache invalidations to other
workers.
However, those flags were not meant to be used with multi-threaded
workers. For instance, a thread may signal registry changes that are
actually made by another thread. It can also happen that a thread
changes the registry, which makes another thread crash (like a thread
modifying a dict while another one iterates over it), and the latter
will reset the registry to its original state because it misinterprets
the registry changes as its own changes.
The situation can even get worse, making threads crash in cascade and
eventually leaving the registry in an inconsistent state. When this
happens, the worker is broken and has to be manually restarted.
The fix consists in making those flags thread-specific. This does not
prevent thread crashing because of concurrent changes, but at least it
avoids leaving the worker in a broken state.

Commit cd12293386 introduced an
optimization in the way that models and their inheritances are loaded,
with this commit we defer the setting of each model class' bases
from the _build_model method to the _prepare_setup method.
This has the advantage of setting any given model class' `__bases__`
attribute only once, but it also means that when _add_manual_models is
called, the __bases__ for ir.model are not yet set (only the default
implementation exists), therefore any module overrides to ir.model do
not take effect when creating the custom models.
This meant that if one creates a custom model with chatter support (i.e.
custom ir.model behaviour implemented in mail) and one restarted the
server, the registry would not properly setup ir.model before creating
the custom model (yielding warnings about tracking and such not being
valid fields) and when creating a record of the custom model, the
registry would crash.
With this commit, ir.model's _prepare_setup is explicitly called before
_add_manual_models to ensure that all overrides to ir.model are taken
into account.

Before this commit searched terms were the ones entered by the end-user.
After this commit if the searched term is not found then the search is
performed on a resembling term.
The similarity is obtained from a Levenshtein distance combined with
ratios of common and different letters.
By default the dictionary against which the search term is matched is
based on the content of the search fields containing a word that starts
with the first letter of the search term.
If the `pg_trgm` Postgresql extension is installed the dictionary is
built from matches using the `<%%` operator (similar to the
`word_similarity` function).
Several approaches were benchmarked during development, those results

When computing the foreign key name,
`check_foreign_keys` didn't take into account the limit of 63 characters
for constraint names.
Because of this, some constraints were dropped and recreated
over and over while they were correct, during install and upgrades.
For instance, when installing `base`
when adding the foreign key for which the name was computed
`base_partner_merge_automatic_wizard_res_partner_rel_base_partner_merge_automatic_wizard_id_fkey`
Postgresql created the constraint under the name
`base_partner_merge_automatic__base_partner_merge_automatic_fkey`
and therefore, as the name did not match,
the constraint was dropped and re-created.

The attributes field.depends and field.depends_context are problematic
for sharing fields across registries, because they depend on the model's
registry class, which may vary from one registry to another. In order
to make computed fields shareable, we have to move those values away
from fields.
For the same reason, field.recursive should not be inferred, because its
value may depend on the registry, although it is generally not the case.
Moreover, the flag recursive=True is set on a field when field triggers
are determined (on the registry). A compute method may be called before
the flag is set (if no update has been done yet), and that can lead to
incorrect computations.
This happened in test TestUsers2.test_reified_groups in module 'base'.
The user groups view was apparently determined without the flag being
set, and the view depends on the recursive field 'trans_implied_ids',
which was not correctly computed.
We thus force developers to be explicit about recursive computed fields.
The code now logs a warning when the flag is not set up properly.
CRM install query count can vary from one execution to another, leading
to difficulties when analysing performances evolution.
The main reason for this is that some compute methods were called in
different order. Even if compute order shouldn't have any effect on the
final result, making it well defined will help finding other causes of
non-determinism.
The initial observation was that sorting Environment.fields_to_compute
leads to a fixed number of query when installing crm.
The main cause of non-determinisim is the usage of `set` impacting
Field.compute_value and BaseModel._modified_triggers.
Transforming all these `set` to `OrderedSet` solves the problem.
The query count is now deterministic when installing a database from
scratch, but not when updating a database with -i crm.

This patch complements the previous one by ensuring that any
`cache_invalidated=True` flag inherited from the master process
(pre-fork mode) cannot trigger a cache clear.
This could occur when the first request is served, because the flag was
never clear in the master process, which never server any request.
At the end of `check_signaling()`, the local cache has either been
cleared because a (real) increment of the cache sequence was detected,
or it is considered still valid. The final state of the
`cache_invalidated` flag should reflect this, by being `False`.

During loading, the registry clears all `ormcache` data multiple
times, in order to ensure consistency with the newly loaded module
data.
Since 083c70bbb6, this was done by
calling `self.clear_caches()`, with the side-effect
of signalling to all other worker processes that the cache
*needs* to be invalidated, which is actually untrue.
If the other workers have any reason to reload their own registries,
they will also clear their own cache in the process - there is no
need to forcefully invalidate it globally.
One could think that combining the pre-fork mode with the `-d <db>`
parameter would mitigate this issue, by making all workers inherit from
a fully loaded registry, In reality it doesn't work, because they also
inherit from the `cache_invalidated=True` flag, that was never cleared
in the master process. So despite having a fully loaded registry, the
newly forked workers will signal a cache invalidation upon serving
their first request.
Further, in a multi-tenant setup with large numbers of databases,
registries may be recycled and loaded much more frequently than
new workers are starting, due to the limited registry LRU, amplifying
this effect a bit.
~~
This patch directly clears the cache LRU without going through
`clear_cache()`, avoiding setting the `cache_invalidated` flag of the
registry, and thus not signalling to other workers.
This is similar to what was being done before 083c70bbb6,
where the LRU was dropped like all other lazy properties.

Before this patch, adding a field on a custom model discards all
automated actions on that model. The explanation is relatively simple.
When models are set up in the registry, the classes of custom models are
dropped then recreated. Given that automated actions are implemented as
monkey-patches on model classes, the setup of models simply loses those
monkey-patches, which explains why they stop working on custom models.
The fix introduces an `_unregister_hook()` method, that is expected to
clean up what has been done in `_register_hook()`. When the registry is
ready (i.e., not being loaded), the setup of models first invokes
`_unregister_hook()` on models, proceeds with the setup, and finally
invokes `_register_hook()` to reinstall the hooks.

Before this, invalidations to the UID cache is not synchronised
between workers because it's an ad-hoc solution (so a user changing
their password or an admin disabling a user would only lock out an
attacker currently using the API of one of possibly several
workers). Shift the entire thing to ormcache which already has proper
support for synchronising cache invalidation between workers.
Also simplify the cache invalidation mess in Users.write because the
caches have been unified into a single registry-level LRU, so the
half-dozen cache clears on specific ormcached methods & models is
pretty much the same as repeatedly calling clear_caches on the current
model.
**However** registry.cache is trivially accessible from server actions
and safe_eval as long as they provide access to a model (through
`model.pool.cache`). Which is common, and an issue given we're very
much putting sensible data in there.
Fix this by renaming `Registry.cache` to `Registry.__cache`, this
requires few editions and mangled names are not accessible from
safe_eval contexts.
The alternative would have been to add more bespoke handling of the
uid cache to hook it into the cache invalidation propagation
machinery.
After discussion with (@)odony, fixing LRU access and using that seems
cleaner and less error-prone.
Note on lazy_property
=====================
Make Registry.cache / Registry.__cache into a regular attribute: the
overhead of the LRU is not that high (compared to that of the registry
itself), it's rare that we *don't* need it, and it's assumed to be a
persisted attribute (it's not just a cache) so making it a normal
attribute seems fine; and lazy_property doesn't work for mangled
names: the name of the property is mangled using the name of the
definition class, but the name of the symbol (fget) is not mangled so
lazy_property would set the __cache attribute but then Python would
lookup _Registry__cache, creating a new cache every access.
And we can't (always) mangle things correctly on `__get__(obj,
owner)`: `owner` is just `type(obj)`, meaning in the case of
inheritance the type we get is the type through which the property is
accessed rather than the one it's defined on. So it would work in the
cases where no inheritance is involved (such as Registry.__cache) but
not in general (lest we want to play around walking the MRO ourselves
to find the definition source, which doesn't seem worth it).
lazy_property *could* be made to work properly on Python 3.6+: the
descriptor protocol gains `__set_name__(name, owner)`, which is called
with the properly mangled name — and with the definition class to boot
(though there might still be issues when overriding lazy properties as
the override will be mangled & named differently... or maybe that's a
feature?). However we're still supporting 3.5 at this point, AFAIK, so
that's not an option. Plus it feels unnecessary / not very useful.
However add an assertion to `lazy_property` so it signals when we try
to use it on a mangled method (as otherwise it kinda sorta work in the
sense that the property / object is accessible but is in effect a
slower way to write a regular property).
This is a followup of commit bc2bb5e03c2b32d4ee1b0597ea5889c17d2b0e0e
When a module is updated, a constraint application may (temporarily)
fail because the existing data does not respect the constraint, this is
OK and can be fixed through hooks/migration scripts and was handled by
the aforementioned commit.
However when updating multiple modules, it is possible that an
inheriting module will try to re-apply the failed constraint and
succeed, if that is the case, when processing the `post_constraints` an
already-existing constraint will be applied and raise an error.
To fix this, a check is made before trying to apply the constraint, to
verify that it is not already in _constraint_queue, if it is not, then
we may attempt to apply it, if it is in the queue, then we may safely
ignore it as it will be applied further down the registry cycle.

Convert these to iterating on the LRU's internal mapping, and also

In some case, a pre-migration script calls `xml_import.parse` to force
reload a no-update data in pre-script. It is possible that fields are
marked to recompute in the process. The problem is that the reference to
the field added in `env.all.tocompute` won't be the same as the
reference of the same field after calling `registry.setup_models()`,
leading to an infinite loop while recomputing this field, since
`fields.__get__` wont find `self` in `env.all.tocompute`.

problem when a custom field is fucked up: its inherited fields will make

faithfully the database, only fields that explicitly depend on the
context have an extra indirection in the cache;
* delay recomputations by default: use method `recompute` to explicitly
flush out pending recomputations;
* delay updates in method `write`: updates are stored in a data
structure that can be flushed efficiently to the database with method
`flush` (which also flush out recomputations);
* make method `modified` take advantage of inverse fields to inverse
dependencies;
* filter records by evaluating a domain on records in Python;
* a computed field with `readonly=False` behaves like a normal field
