The second one is because our bots have the libc debug info package installed,
the first, no idea.

[lldb-dap] Test Gardening, improving DebugCommunication. (#141689)
Improving the readability and correctness of DebugCommunication by
adding type annotations to many parts of the library and trying to
improve the implementation of a few key areas of the code to better
handle correctness.

Specifically, this refactored the
`DebugCommunication._handle_recv_packet` function to ensure consistency
with the reader thread when handling state changes and improved the
`DebugCommunication._recv_packet` helper to make it easier to follow by
adding some additional helpers.

[lldb-dap] Adding additional asserts to unit tests. (#140107)
Adding an assert that the 'continue' request succeeds caused a number of
tests to fail. This showed a number of tests that were not specifying if
they should be stopped or not at key points in the test. This is likely
contributing to these tests being flaky since the debugger is not in the
expected state.

Additionally, I spent a little time trying to improve the readability of
the dap_server.py and lldbdap_testcase.py.

[lldb-dap] Re-enable the lldb-dap tests (#138791)
Re-enable the lldb-dap tests. We've spent the last week improving the
reliability of the test suite and the tests now pass reliably on macOS
and Linux at desk. Let's see how things fare on the bots.

[lldb-dap] Give attach test binaries unique names (#138435)
Give the test binaries used for attaching unique names to avoid
accidentally attaching to the wrong binary.

2dbab4ca8d [lldb][test] Disable a bunch of flakey lldb-dap tests
These, or parts of these, are all failing every so often on Linaro's
build bots with:
    raise ValueError(desc)
ValueError: no response for "disconnect"

Sorry to use a global disable here but this is happening too often
and spamming unrelated PRs.

I think it's the same issue as https://github.com/llvm/llvm-project/issues/137660.

[lldb-dap] Adaptor -> Adapter (NFC) (#129110)
Both spellings are considered correct and acceptable, with adapter being
more common in American English. Given that DAP stands for Debug Adapter
Protocol (with an e) let's go with that as the canonical spelling.

[lldb-dap] Automatically skip lldb-dap tests for remote platforms (#93169)
The don't currently work (and they're also not particularly useful,
since all of the remote stuff happens inside lldb).

This saves us from annotating tests one by one.

[lldb] Fixed the DAP tests in case of a remote target (#92398)
These tests failed in case of Windows host and Linux target, because
dap_server tried to run ELF file on Windows.

[lldb][dap] Avoid concurrent HandleCommand calls (#83162)
The `EventThreadFunction` can end up calling `HandleCommand`
concurrently with the main request processing thread. The underlying API
does not appear to be thread safe, so add a narrowly scoped mutex lock
to prevent calling it in this place from more than one thread.

Fixes #81686. Prior to this, TestDAP_launch.py is 4% flaky. After, it
passes in 1000 runs.

[lldb-dap] Implement command directives (#74808)
This adds support for optionally prefixing any command with `?` and/or
`!`.
- `?` prevents the output of a commands to be printed to the console
unless it fails.
- `!` aborts the dap if the command fails.

They come in handy when programmatically running commands on behalf of
the user without wanting them to know unless they fail, or when a
critical setup is required as part of launchCommands and it's better to
abort on failures than to silently skip.
