* Migrate most RAW_LOGs and RAW_CHECKs in tests to regular LOG and CHECK.Gravatar Andy Getzendanner2023-05-23
| | | | | | | | | | | The non-RAW_ versions provide better output but weren't available when most of these tests were written. There are just a couple spots where RAW_ is actually needed, e.g. signal handlers and malloc hooks. Also fix a couple warnings in layout_test.cc newly surfaced because the optimizer understands CHECK_XX differently than INTERNAL_CHECK.

* Fix handling of `CHECK` macros in static analysis tools.Gravatar Abseil Team2023-04-24
| | | | | | | Currently static analysis tools built using the Clang Dataflow Analysis framework can't prove that code under `switch (0) case 0:` is executed on all paths. The Clang Dataflow Analysis framework should ultimately be improved to handle these cases. In the meantime, to enable the use of such tools in their current state, we add a `default` case back to the `switch` statement in `ABSL_LOG_INTERNAL_STATELESS_CONDITION` to help them understand that the code is executed on all paths.

* Initialize ScopedMockLog.is_triggered_ with false.Gravatar Abseil Team2023-02-23
| | | | | | | | | In C++20, this happens by default, but in C++17, it's left uninitialized if no logs are sent and StartCapturingLogs is never called. The destructor then makes an attempt to access it, which is both unsafe and not very useful while it is uninitialized. Also add a test that expects the appropriate CHECK fail when StartCapturingLogs is not called. PiperOrigin-RevId: 511865440 Change-Id: Ie23ff3f901e926761d5f487e10d33c21c3bd43d3

* Prevent all CHECK functions from expanding macros for the error string.Gravatar Mike Kruskal2022-12-13
| | | | | | | | | This was likely an unintentional behavior change made a while ago while trying to reduce duplication. The new behavior will always include the unexpanded macro in the error string. For example, `CHECK_EQ(MACRO(x), MACRO(y))` will now output "MACRO(x) == MACRO(y)" if it fails. Before this change, CHECK and QCHECK were the only macros that had this behavior. Not using function-like macro aliases is a possible alternative here, but unfortunately that would flood the macro namespace downstream with CHECK* and break existing code.

* Fixing macro expansion changes in new logging macros.Gravatar Mike Kruskal2022-12-08
| | | | | | | | | This was an unintentional behavior change when we added a new layer of macros. Not using function-like macro aliases would get around this, but unfortunately that would flood the macro namespace downstream with CHECK and LOG (and break existing code). Note, the old behavior only applied to CHECK and QCHECK. Other CHECK macros already had multiple layers of function-like macros and were unaffected.
