Even after repeated adjustment of the constants, this test still fails
randomly. It has educated us to ignore messages from Jenkins, to a
point where we missed some actual failures. In addition, it accounts
for a non-negligible percentage of the run time of the test suite
just by itself. Since no one has proposed a convincing patch in months,
I'm going to remove the patch. We can't keep a randomly failing test
forever.
Unlike other model fields, the newly introduced (1.4)
GenericIPAddressField did not accept verbose_name and name as the
first positional arguments. This commit fixes it.
Thanks Dan McGee for the report and the patch.
The joins for nested nullable foreign keys were often created as INNER
when they should have been OUTER joins. The reason was that only the
first join in the chain was promoted correctly. There were also issues
with select_related etc.
The basic structure for this problem was:
A -[nullable]-> B -[nonnull]-> C
And the basic problem was that the A->B join was correctly LOUTER,
the B->C join not.
The major change taken in this patch is that now if we promote a join
A->B, we will automatically promote joins B->X for all X in the query.
Also, we now make sure there aren't ever join chains like:
a LOUTER b INNER c
If the a -> b needs to be LOUTER, then the INNER at the end of the
chain will cancel the LOUTER join and we have a broken query.
Sebastian reported this problem and did also major portions of the
patch.
The ORM generated a query with INNER JOIN instead of LEFT OUTER JOIN
in a somewhat complicated case. The main issue was that there was a
chain of nullable FK -> non-nullble FK, and the join promotion logic
didn't see the need to promote the non-nullable FK even if the
previous nullable FK was already promoted to LOUTER JOIN. This resulted
in a query like a LOUTER b INNER c, which incorrectly prunes results.
Made two-digit hours and minutes mandatory in tzinfo (the code used
to crash if a one-digit representation was provided).
Added standalone tests for django.utils.dateparse.
Remove the params variable from the context and just put the variables
in directly.
This had not been committed previously as the original pattern was used
in the functional generic views and we wanted consistency between them,
but django.views.generic.simple.direct_to_template is now gone so we can
do it 'right'.
Patch by @jphalip updated to apply, documentation and release notes
added.
I've documented strip_tags as well as remove_tags as the difference
between the two wouldn't be immediately obvious.
We should catch all exceptions in the thread to ensure it doesn't die
with an unhandled exception. The type of the exception is already
checked further in the test.
An ordering test had two problems related to dict.items() usage:
- It assumed the order of the dict was non-randomized
- It indexed to the dict.items() which is py3 incompatible.
I fixed the test by using dict['rank'] directly, where rank is the
column tested on the values queryset.
Deferred models now automatically update only the fields which are
loaded from the db (with .only() or .defer()). In addition, any field
set manually after the load is updated on save.
This patch removes an unconditional float(value) conversion from db
backend default convert_values() method. This can cause problems when
aggregating over character fields for example. In addition, Oracle
and SQLite already return the bare value from their convert_values().
In the long term the converting should be done by fields, and the
fields should then call database backend specific converters when
needed. The current setup is inflexible for 3rd party fields.
Thanks to Merlijn van Deen for the original patch.
* Renamed the __unicode__ methods
* Applied the python_2_unicode_compatible decorator
* Removed the StrAndUnicode mix-in that is superseded by
python_2_unicode_compatible
* Kept the __unicode__ methods in classes that specifically
test it under Python 2
* Renamed smart_unicode to smart_text (but kept the old name under
Python 2 for backwards compatibility).
* Renamed smart_str to smart_bytes.
* Re-introduced smart_str as an alias for smart_text under Python 3
and smart_bytes under Python 2 (which is backwards compatible).
Thus smart_str always returns a str objects.
* Used the new smart_str in a few places where both Python 2 and 3
want a str.
cleaned_data is no longer deleted when form validation fails but only
contains the data that did validate.
Thanks to the various contributors to this patch (see ticket).
The keys/items/values methods return iterators in Python 3, and the
iterkeys/items/values methods don't exist in Python 3. The behavior
under Python 2 is unchanged.
Previously, the flush was done before the test case execution and now
it is performed after it.
Other changes to the testing infrastructure include:
* TransactionTestCase now doesn't reset autoincrement sequences either
(previous behavior can achieved by using `reset_sequences`.)
With this, no implicit such reset is performed by any of the provided
TestCase classes.
* New ordering of test cases: All unittest tes cases are run first and
doctests are run at the end.
THse changes could be backward-incompatible with test cases that relied
on some kind of state being preserved between tests. Please read the
relevant sections of the release notes and testing documentation for
further details.
Thanks Andreas Pelme for the initial patch. Karen Tracey and Anssi
Kääriäinen for the feedback and Anssi for reviewing.
This also fixes#12408.
In particular, allow the '--' sequence to be present in string
values without being interpreted as comment marker.
Thanks Tim Chase for the report and shaleh for the initial patch.
Also removed the hasattr check when firing request_finished signal for
caches with a 'close' method. Should be safe to call `cache.close`
everywhere now
The qs.bulk_create() method did not work with large batches together
with SQLite3. This commit adds a way to split the bulk into smaller
batches. The default batch size is unlimited except for SQLite3 where
the batch size is limited to 999 SQL parameters per batch.
Thanks to everybody who participated in the discussions at Trac.
At least Oracle needs parentheses in negated where conditions, even if
there is only single condition negated. Fixed this by reverting to old
logic in that part of as_sql() and adding a comment about this.
I did not investigate why the parentheses are needed. The original
offending commit was bd283aa844.
When the postgresql_psycopg2 backend was used with DB-level autocommit
mode enabled, after entering transaction management and then leaving
it, the isolation level was never set back to autocommit mode.
Thanks brodie for report and working on this issue.
Made sure the WhereNode.as_sql() handles various EmptyResultSet and
FullResultSet conditions correctly. Also, got rid of the FullResultSet
exception class. It is now represented by '', [] return value in the
as_sql() methods.
This commit tackles a couple of issues. First, in certain cases there
were some mixups if field.attname or field.name should be deferred.
Field.attname is now always used.
Another issue tackled is a case where field is both deferred by
.only(), and selected by select_related. This case is now an error.
A lot of thanks to koniiiik (Michal Petrucha) for the patch, and
to Andrei Antoukh for review.
Added ability to use receiver decorator in the following way:
@receiver([post_save, post_delete], sender=MyModel)
def signals_receiver(sender, **kwargs):
...
Previously, the closing token for the verbatim tag was specified as the
first argument of the opening token. As pointed out by Jannis, this is
a rather major departure from the core tag standard.
The new method reflects how you can give a specific closing name to
{% block %} tags.
In addition, removed a possibly problematic .filter() call from
backends.test_query_encoding test. It is possible the .filter could
cause collation problems on MySQL, and as it wasn't absolutely needed
for the test it seemed better to get rid of the call.
Refs #18461.
Connection.features does not need to be confirmed any more, after
commit aa42357, rendering obsolete the workaround when using
TEST_MIRROR (Refs #16885, #17760).
This does remove the requirement to call features.confirm() method
before checking the properties.
Thanks cdestiger and Ramiro Morales for their work on the patch.
Generic views assumed any object's _meta will be model Options. This
is not true for ModelForms for example. Took isinstance(obj, Model)
in use instead.
Fixed#18381 -- Stopped escaping object ids
when passing them to the contenttypes.shortcut view.
Thanks apollo13 for the patch and dhepper for the review.
On MySQL when checking the server version, a new connection could be
created but never closed. This could result in open connections on
server startup.
When order_by causes new joins to be added to the query, the joins must
be LEFT OUTER joins for nullable relations, otherwise the order_by
could cause the results to be altered. This commit fixes the logic to
only promote new joins, previously all joins in the order_by lookup
path were promoted.
Thanks to Bruno Desthuilliers for spotting this corner case.
A test in model_fields used LEN() in raw SQL. This function is not
available on some 3rd party backends. I removed this function and
ensured that the test works correctly (breaks pre e9bbdb39de) with
the change.
after the full file name is generated by the storage class.
Thanks Refefer for the report, carsongee for the patch, and
everyone else involved in the discussion.
Fixed#18248 -- proxy models were added to included_inherited_models
in sql.query.Query. The variable is meant to be used for multitable
inheritance only. This mistake caused problems in situations where
proxy model's query was reused.
Introduced a distinct implementation depending on the type of the
date field (DateField or DateTimeField), and applied appropriate
conversions is the latter case, when time zone support is enabled.
Fixed#18175 -- Calling SortedDict.__copy__() resulted in changes to
the original dictionary. The reason was likely related to subclassing
dict.
Thanks to linovia for report and patch.
Fixed#15933, #18082 -- the get_indexes() method introspection was
done inconsitently depending on the backend. For example SQLite
included all the columns in the table in the returned dictionary,
while MySQL introspected also multicolumn indexes.
All backends return now consistenly only single-column indexes.
Thanks to andi for the MySQL report, and ikelly for comments on
Oracle's get_indexes() changes.
Fixed#17957 -- when using Oracle and character fields, the fields
were set null = True to ease the handling of empty strings. This
caused problems when using multiple databases from different vendors,
or when the character field happened to be also a primary key.
The handling was changed so that NOT NULL is not emitted on Oracle
even if field.null = False, and field.null is not touched otherwise.
Thanks to bhuztez for the report, ramiro for triaging & comments,
ikelly for the patch and alex for reviewing.
QuerySet had previously some complex logic for dealing with nullable
fields in negated add_filter() calls. It seems the logic is leftover
from a time where the WhereNode wasn't as intelligent in handling
field__in=[] conditions.
Thanks to aaugustin for comments on the patch.
Handled values returned by functions more like field values.
In particular, localized dates, times and datetimes properly,
and converted datetimes to the current timezone.
Fixed#18218 -- previously Django's introspection table_names() and
get_table_list() methods did not sort the output consistently. This
resulted in random order of inspected models.
This commit also removed all external usages of get_table_list().
table_names() should be used instead.
Thanks to claudep for patch and report.
