Russell Keith-Magee 64be8f29d5 Fixed #9253 -- Modified the method used to generate constraint names so that it is consistent regardless of machine word size.
NOTE: This change is backwards incompatible for some users.

If you are using a 32-bit platform, you will observe no differences as a
result of this change. However, users on 64-bit platforms may experience
some problems using the `reset` management command.

Prior to this change, 64-bit platforms would generate a 64-bit, 16 character
digest in the constraint name; for example:

ALTER TABLE `myapp_sometable` ADD CONSTRAINT `object_id_refs_id_5e8f10c132091d1e` FOREIGN KEY ...

Following this change, all platforms, regardless of word size, will
generate a 32-bit, 8 character digest in the constraint name; for example:

ALTER TABLE `myapp_sometable` ADD CONSTRAINT `object_id_refs_id_32091d1e` FOREIGN KEY ...

As a result of this change, you will not be able to use the `reset`
management command on any table created with 64-bit constraints. This
is because the the new generated name will not match the historically
generated name; as a result, the SQL constructed by the `reset` command
will be invalid.

If you need to reset an application that was created with 64-bit
constraints, you will need to manually drop the old constraint prior
to invoking `reset`.

Gary Wilson Jr d89ba464dd Changes to `ImageFileDescriptor` and `ImageField` to fix a few cases of setting image dimension fields.
* Moved dimension field update logic out of `ImageFileDescriptor.__set__` and into its own method on `ImageField`.
 * New `ImageField.update_dimension_fields` method is attached to model instance's `post_init` signal so that:
   * Dimension fields are set when defined before the ImageField.
   * Dimension fields are set when the field is assigned in the model constructor (fixes #11196), but only if the dimension fields don't already have values, so we avoid updating the dimensions every time an object is loaded from the database (fixes #11084).
 * Clear dimension fields when the ImageField is set to None, which also causes dimension fields to be cleared when `ImageFieldFile.delete()` is used.
 * Added many more tests for ImageField that test edge cases we weren't testing before, and moved the ImageField tests out of `file_storage` and into their own module within `model_fields`.

Jacob Kaplan-Moss 2b0903b2c4 Fixed #10404: ImageField height_field and width_field options no longer depend on putting the image field after the height/width fields as they did after r9766.
This bug actually exposed a related handful of inconsistancies in the underlying file handling and wraping, so a few related changes are in here as well:

    * Dimensions are also now calculated the moment the image is assigned to the field instead of upon save.
    * The base `File` object now when possible delegates its closed attribute down to the os-level file it wrapps.
    * In-memory files' `close()` now is a no-op. Without this certain APIs that should be able to handle in-memory files were failing.
    * Accessing `FieldFile.closed` used to open the file. That's silly, and it doesn't any more.
    * Some over-eager error handling was squishing some errors that would normally be raised. One unit test was incorrectly depending on this behavior, so the test was removed.

Thanks to Armin Ronacher for much of this work.

this version.

Affects the postgresql_psycopg2 backend only. We now don't use the

Malcolm Tredinnick 7d9b29a56d Use plain model.Manager, or suitable proxy, for model saving.
We can't use the default manager in Model.save_base(), since we need to
retrieve existing objects which might be filtered out by that manager. We now
always use a plain Manager instance at that point (or something that can
replace it, such as a GeoManager), making all existing rows in the
database visible to the saving code.

The logic for detecting a "suitable replacement" plain base is the same as for
related fields: if the use_for_related_fields is set on the manager subclass,
we can use it. The general requirement here is that we want a base class that
returns the appropriate QuerySet subclass, but does not restrict the rows
returned.

Fixed #8990, #9527.

This will make it easier for multiple database support. Thanks to Alex Gaynor for the initial patch.
This is backwards-compatible but will likely break third-party database backends. Specific API changes are:

* BaseDatabaseWrapper.__init__() now takes a settings_dict instead of a settings module. It's called settings_dict to disambiguate, and for easy grepability. This should be a dictionary containing DATABASE_NAME, etc.

* BaseDatabaseWrapper has a settings_dict attribute instead of an options attribute. BaseDatabaseWrapper.options is now BaseDatabaseWrapper['DATABASE_OPTIONS']

* BaseDatabaseWrapper._cursor() no longer takes a settings argument.

* BaseDatabaseClient.__init__() now takes a connection argument (a DatabaseWrapper instance) instead of no arguments.

Malcolm Tredinnick 14c8e5227a Changed the row count value returned from update queries in some cases.
If an update only affected an ancestor model (not the child), we were
returning 0 for the number of rows updated. This could have been
misleading if the value is used to detect an update occuring. So we now
return the rowcount from the first non-trivial query that is executed
(if any). Still a slight compromise, but better than what we had.

Karen Tracey 344f16e220 Fixed #8138 -- Changed django.test.TestCase to rollback tests (when the database supports it) instead of flushing and reloading the database. This can substantially reduce the time it takes to run large test suites.
This change may be slightly backwards incompatible, if existing tests need to test transactional behavior, or if they rely on invalid assumptions or a specific test case ordering.  For the first case, django.test.TransactionTestCase should be used.  TransactionTestCase is also a quick fix to get around test case errors revealed by the new rollback approach, but a better long-term fix is to correct the test case.  See the testing doc for full details.

Malcolm Tredinnick 062a94ef45 Reconciling where- and having-clause behaviour.
Extricated the code that works directly with SQL columns (standard
"where" stuff) from the the code that takes SQL fragments and combines
it with lookup types and values. The latter portion is now more
generally reusable. Any existing code that was poking at Query.having
will now break in very visible ways (no subtle miscalculations, which is
a good thing).

This patch, en passant, removes the existing "having" test, since the
new implementation requires more setting up than previously. The
aggregates support (currently in a separate codebase) has tests for this
functionality that work as a replacement for the removed test.

Malcolm Tredinnick f1f1d366c8 Removed django.db.models.options.Options.one_to_one_field.
The last use of it was removed in r9641 (it's internal API) and it's been
broken since r7477, as there's no longer a maximum of one OneToOneField per
model, so anything relying on it contained subtle bugs.

Malcolm Tredinnick a1cbeb9afb If an SQL query doesn't specify any ordering, avoid the implicit sort
that happens with MySQL when a "GROUP BY" clause is included. This is a
backend-specific operation, so any other databases requiring similar
encouragement can have a function added to their own backend code.

This means that accidentally executing HugeStoryArchive.objects.all() at the
interactive prompt (or in the debug template) won't try to load all 4,233,010
stories into memory and print them out. That would previously cause resource
starvation and other "interesting" crashes.

If you really, really want the previous behaviour (e.g. in a doctest that
prints more than 20 items), display "list(qs)" instead of just "qs".
