This adds support for using PGroonga to back the Zulip full-text
search feature. Because built-in PostgreSQL full text search doesn't
support languages that don't put space between terms such as Japanese,
Chinese and so on. PGroonga supports all languages including Japanese
and Chinese.
Developers will need to re-provision when rebasing past this patch for
the tests to pass, since provision is what installs the PGroonga
package and extension.
PGroonga is enabled by default in development but not in production;
the hope is that after the PGroonga support is tested further, we can
enable it by default.
Fixes#615.
[docs and tests tweaked by tabbott]
This new helper combines two old helpers, one of which was misnamed
and the other of which was always called after the first, so it
made sense to just combine the helpers.
Fixes: #1386
This commit adds these two tests:
test_use_first_unread_anchor_with_some_unread_messages
test_use_first_unread_anchor_with_no_unread_messages
The new tests add coverage to the conditional logic in
get_old_messages_backend() that looks at first_unread_result
when use_first_unread_anchor is set to True.
The test is now called test_use_first_unread_anchor_with_muted_topics().
Before this commit, the test exercised setting
use_first_unread_anchor to True, but it didn't inspect the
most relevant query affected by the flag. Now it does.
This test is still kind of hard to read, and it's far from ideal,
but I'm reluctant to remove it from the test suite.
This increases test coverage by exercising highlight_string().
It also gives deeper test coverage to NarrowBuilder.by_search(),
which had test coverage before, but only in terms of inspecting
the SQL that was generated. This test actually runs the SQL
under the hood.
This partly fixes#1006.
