String UDA defer the evaluation of the sort_compare method
to the '<' operator of the Variant class, since the logic for
comparing string UDAs (which can have custom sort orders) is
already implemented there.
However, since primary use case of Variant is the filter evaluation,
it handles trivial (empty) values in a manner which does not allow
for its direct usage as the comparison operator between sort UDAs.
When filtering, a trivial (empty) value should neither match
'uda < A' nor 'uda >= A'. However, when sorting tasks upon values of
this UDA, precisely one of the above expressions *must* be true.
This commit implements the UDA string sorting logic directly in
the sort_compare method.
- 'priority.long' and 'priority.short' formats now map to 'priority', and
generate a warning.
- Man page updated.
- Converted priority urgency coefficients to UDA equivalents.
- Converted priority color rules to UDA color rules.
- Removed 'default.priority' support.
- Removed special sort handling for 'priority' field in Variant, added special
UDA sort handling.
- Removed ColPriority.{h,cpp} source files.
- Removed asorted newly-unused variables.
- The 'show' command now highlights unused priority settings.
- Removed unused localized priority-relateѕ strings.
- Added legacy mapping for columns and sort columns for 'priority.long' and
'priority.short' columns in report definitions.
- Removed priority color rules implementation.
- Removed obsolete tests for #860, #990, custom.priority_long.t.
- Updated various tests that set priority default, colors.
- Many files were missing an explicit cmake.h include. Some were not including
it at all. Now it's used almost everywhere.
(cherry picked from commit 82ae86979c497e6d1d0c6b2b5a55aa379ec82c98)
- Added support for more type-specific checks of attribute values.
- Added support for more type-specific attribute rendering.
- Improved generalized methods for checking columns in a report.
- Added unit tests.
- Minor code cleanup.
- Added secret hidden feature for internal testing.
- Change the was performance measurements are taken. This in preparation
to automated daily perf charts, leading to efforts to speed up certain
operations.
