Before we introduce additional features for controlling overlay analysis
enablement, change the unit tests to specify features directly instead
of through a isFeatureEnabled boolean field.
In an upcoming change, getOverlayDatabaseMode() will depend on the
contents of Config. As a result, getOverlayDatabaseMode() needs to be
called after the rest of Config has already been populated.
This commit performs the refactoring to move the
getOverlayDatabaseMode() into initConfig(), after the rest of Config has
already been populated.
The loadConfig() function is mostly the same as getDefaultConfig(),
except that it calls loadUserConfig() and stores the results in
originalUserInput.
This refactoring commit replaces the loadConfig() call with
getDefaultConfig() and loadUserConfig(), which allows deleting a large
amount of duplicated code.
This commit adds useOverlayDatabaseCaching to AugmentationProperties to
indicate whether the action should upload overlay-base databases to the
actions cache and to download a cached overlay-base database when
creating an overlay database.
This commit changes getOverlayDatabaseMode so that, when
Feature.OverlayAnalysis is enabled, it calculates the overlay database
mode automatically based on analysis metadata. If we are analyzing the
default branch, use OverlayBase, and if we are analyzing a PR, use
Overlay.
If CODEQL_OVERLAY_DATABASE_MODE is set to a valid overlay database mode,
that environment variable still takes precedence.
This commit changes databaseInitCluster() to use overlayDatabaseMode
from AugmentationProperties instead of the overlayDatabaseMode
parameter. There is no behavior change because both overlayDatabaseMode
values are computed the same way.
The commit then cleans up the overlayDatabaseMode parameter and the code
paths that feed into it.
This commit adds overlayDatabaseMode to AugmentationProperties and
creates a placeholder getOverlayDatabaseMode() function, with the
necessary inputs, to populate it.
