Mariusz Felisiak 1760ad4e8c
Relaxed some query ordering assertions in various tests. 
It accounts for differences seen on MySQL with MyISAM storage engine.

Made select_for_update() don't raise TransactionManagementError on databases that don't support transactions. 2022-04-14 07:53:15 +02:00
Tim Graham db83ac48d4 Expanded QuerySet.explain() error message if a backend supports no formats. 2022-04-14 06:46:42 +02:00
Mariusz Felisiak 0b63124c84
Improved ExplainTests.test_basic(). 
QuerySet.select_for_update() is not supported by all databases.
Moreover it cannot be used outside of a transaction.

mgaligniana 0ad5316f22 Fixed #24296 -- Made QuerySet.exists() clear selected columns for not sliced distinct querysets. 2022-04-12 08:18:22 +02:00
mgaligniana d2263b7b87 Refs #18414 -- Added tests for selected columns of sliced distinct querysets. 2022-04-12 08:18:22 +02:00

Mariusz Felisiak 6723a26e59 Fixed CVE-2022-28347 -- Protected QuerySet.explain(**options) against SQL injection on PostgreSQL. 2022-04-11 08:59:58 +02:00

Matt Hanson, David Briggs, and a security researcher: Danylo Dmytriiev
(DDV_UA) for the report.

Nick Pope 847f46e9bf
Removed redundant QuerySet.all() calls in docs and tests. 
Most QuerySet methods are mapped onto the Manager and, in general,
it isn't necessary to call .all() on the manager.

Simon Charette d35ce682e3 Fixed #33506 -- Made QuerySet.bulk_update() perform atomic writes against write database. 
The lack of _for_write = True assignment in bulk_update prior to
accessing self.db resulted in the db_for_read database being used to
wrap batched UPDATEs in a transaction.

Also tweaked the batch queryset creation to also ensure they are
executed against the same database as the opened transaction under all
circumstances.

Mariusz Felisiak 7119f40c98 Refs #33476 -- Refactored code to strictly match 88 characters line length. 2022-02-07 20:37:05 +01:00
django-bot 9c19aff7c7 Refs #33476 -- Reformatted code with Black. 2022-02-07 20:37:05 +01:00
Mariusz Felisiak c5cd878382
Refs #33476 -- Refactored problematic code before reformatting by Black. 
In these cases Black produces unexpected results, e.g.

def make_random_password(
    self,
    length=10,
    allowed_chars='abcdefghjkmnpqrstuvwxyz' 'ABCDEFGHJKLMNPQRSTUVWXYZ' '23456789',
):

or

cursor.execute("""
SELECT ...
""",
    [table name],
)

Thanks Eugene Kovalev for the initial patch, Simon Charette for the
review, and Chetan Khanna for help.

Jacob Walls e17ab0af91 Fixed tests.queries.models.StaffUser.__str__(). 2021-10-08 06:25:17 +02:00
Mariusz Felisiak 903aaa35e5
Fixed #33159 -- Reverted "Fixed #32970 -- Changed WhereNode.clone() to create a shallow copy of children." 
This reverts commit e441847eca.

A shallow copy is not enough because querysets can be reused and
evaluated in nested nodes, which shouldn't mutate JOIN aliases.

Thanks Michal Čihař for the report.

Simon Charette b81c7562fc Fixed #32717 -- Fixed filtering of querysets combined with the | operator. 
Address a long standing bug in a Where.add optimization to discard
equal nodes that was surfaced by implementing equality for Lookup
instances in bbf141bcdc.

Thanks Shaheed Haque for the report.
 2021-05-13 07:26:52 +02:00
Hasan Ramezani 8de4ca74ba Fixed #32693 -- Quoted and lowercased generated column aliases. 2021-05-04 07:36:56 +02:00
Simon Charette c8b6594305 Fixed #32632, Fixed #32657 -- Removed flawed support for Subquery deconstruction. 
Subquery deconstruction support required implementing complex and
expensive equality rules for sql.Query objects for little benefit as
the latter cannot themselves be made deconstructible to their reference
to model classes.

Making Expression @deconstructible and not BaseExpression allows
interested parties to conform to the "expression" API even if they are
not deconstructible as it's only a requirement for expressions allowed
in Model fields and meta options (e.g. constraints, indexes).

Thanks Phillip Cutter for the report.

This also fixes a performance regression in bbf141bcdc.

Used assertCountEqual() in ExcludeTests.test_exclude_subquery(). 2021-04-22 10:47:10 +02:00
Simon Charette 6d0cbe42c3 Fixed #32650 -- Fixed handling subquery aliasing on queryset combination. 
This issue started manifesting itself when nesting a combined subquery
relying on exclude() since 8593e162c9 but
sql.Query.combine never properly handled subqueries outer refs in the
first place, see QuerySetBitwiseOperationTests.test_subquery_aliases()
(refs #27149).

Thanks Raffaele Salmaso for the report.
