Wrap the Parser.compile_filter method call with a try/except and call the
newly added Parser.compile_filter_error(). Overwrite this method in the
DebugParser to throw the correct error.
Since this error was otherwise catched by the compile_function try/except
block the debugger highlighted the wrong line.
The reason was that the except clause needed to remove a connection
from the django.db.connections dict, but other parts of Django do not
expect this to happen. In addition the except clause was silently
swallowing the exception messages.
Refs #19707, special thanks to Carl Meyer for pointing out that this
approach should be taken.
When a query had a complex where condition (a condition targeting more
than the base table) a subquery was used for deletion. However, the
query had default ordering from the model's meta and Oracle doesn't
work with ordered subqueries.
The regression was caused by fast-path deletion code introduced in
1cd6e04cd4 for fixing #18676.
Thanks to Dylan Klomparens for the report.
Also, according to the comments on the ticket and its duplicates, added
tests execising saving an instance of a model with a GFK to:
* An unsaved object -- This actually doesn't generate the same failure
but another ORM-level exception. The test verifies it's the case.
* An instance of a model with a __nonzero__() method thant returns False
for it. This doesn't fail because that code path isn't executed.
* An instance of a model with a CharField PK and an empty value for it.
This doesn't fail.
They are handled independently now and the latter can be influenced by
the new BaseCommand.leave_locale_alone internal option.
Thanks chrischambers for the report, Claude, lpiatek, neaf and gabooo for
their work on a patch, originally on refs. #17379.
They are simply ignored now. This allows for a more correct behavior when
they are placed before translatable constructs on the same line.
Previously, the latter were wrongly ignored because the former were
preserved when converting template code to the internal Python-syntax
form later fed to xgettext but Python has no ``/* ... */``-style
comments.
Also, special comments directed to translators are now only taken in
account when they are located at the end of a line. e.g.::
{# Translators: ignored #}{% trans "Literal A" %}{# Translators: valid, associated with "Literal B" below #}
{% trans "Literal B" %}
Behavior of ``{% comment %}...{% endcomment %}``tags remains unchanged.
Thanks juneih at redpill-linpro dot com for the report and Claude for
his work on the issue.
