l.t.t.t.TestSharingMigrationPerformance(TestCaseWithFactory, TranslatedProductMixin) : class documentation

Part of lp.translations.tests.test_translationmerger View In Hierarchy

Test performance-related aspects of migration.

Memory usage is a particular problem for this script, so this class particularly looks for regressions in that area.

Method setUp Undocumented
Method assertNoStatementsInvolvingTable The specified table name is not in any of the statements.
Method test_merging_loads_no_msgids_or_potranslations Undocumented
Method _flushDbObjects Flush ORM-backed objects from memory as much as possible.
Method _resetReferences Reset translation-related references in the test object.

Inherited from TestCaseWithFactory:

Method getUserBrowser Return a Browser logged in as a fresh user, maybe opened at url.
Method getNonRedirectingBrowser Undocumented
Method createBranchAtURL Create a branch at the supplied URL.
Method create_branch_and_tree Create a database branch, bzr branch and bzr checkout.
Method createBzrBranch Create a bzr branch for a database branch.
Static Method getBranchPath Return the path of the branch in the mirrored area.
Method useTempBzrHome Undocumented
Method useBzrBranches Prepare for using bzr branches.

Inherited from TestCase (via TestCaseWithFactory):

Method becomeDbUser Commit, then log into the database as dbuser.
Method __str__ The string representation of a test is its id.
Method useContext Use the supplied context in this test.
Method makeTemporaryDirectory Create a temporary directory, and return its path.

Method assertProvides Assert 'obj' correctly provides 'interface'.
Method assertNotifies Assert that a callable performs a given notification.
Method assertNoNotification Assert that no notifications are generated by the callable.
Method assertSqlAttributeEqualsDate Fail unless the value of the attribute is equal to the date.
Method assertTextMatchesExpressionIgnoreWhitespace Undocumented
Method assertIsInstance Assert that an instance is an instance of assert_class.
Method assertIsNot Assert that expected is not the same object as observed.
Method assertContentEqual Assert that 'iter1' has the same content as 'iter2'.
Method assertRaisesWithContent Check if the given exception is raised with given content.
Method assertBetween Assert that 'variable' is strictly between two boundaries.
Method assertVectorEqual Apply assertEqual to all given pairs in one go.
Method expectedLog Expect a log to be written that matches the regex.
Method pushConfig Push some key-value pairs into a section of the config.
Method attachOopses Undocumented
Method attachLibrarianLog Include the logChunks from fixture in the test details.
Method assertStatementCount Assert that the expected number of SQL statements occurred.
Method useTempDir Use a temporary directory for this test.
Method assertEmailHeadersEqual Assert that two email headers are equal.
Method assertStartsWith Undocumented
Method assertEndsWith Asserts that s ends with suffix.
Method checkPermissions Check if the used_permissions match expected_permissions.
Method assertEmailQueueLength Pop the email queue, assert its length, and return it.
Method _unfoldEmailHeader Unfold a multiline email header.

Inherited from TranslatedProductMixin:

Method setUpProduct Undocumented
Method _makeTranslationMessage Set a translation for given message in given translation.
Method _makeTranslationMessages Translate the POTMsgSets in our trunk and stable templates.
Method _getPOTMsgSet Get POTMsgSet for given template.
Method _getPOTMsgSets Get POTMsgSets in our trunk and stable series.
Method _getMessage Get TranslationMessage for given POTMsgSet in given template.
Method _getMessages Get current TranslationMessages in trunk and stable POTMsgSets.
Method _getTranslation Get (singular) translation string from TranslationMessage.
Method _getTranslations Get translated strings for trunk and stable POTMsgSets.
def setUp(self):
def _flushDbObjects(self):
Flush ORM-backed objects from memory as much as possible.

This involves a commit.

def _resetReferences(self):
Reset translation-related references in the test object.

This stops the test itself from pinning things in memory as caches are cleared.

Transactions are committed and the templates list is discarded and rebuilt to get rid of pinned objects.

def assertNoStatementsInvolvingTable(self, table_name, statements):
The specified table name is not in any of the statements.
def test_merging_loads_no_msgids_or_potranslations(self):
