Not all GDB errors are shown in the debug console?

[GitMensch]

I've wondered why a launch configuration did not work, and only after "openGdbConsole": true, was enabled I've seen it there: "symbol lookup error: undefined symbol" (there was a bad .so in LD_LIBRARY_PATH).

Any idea why this was not reported by the debug adapter to the ui?`

IIUC the error message appeared in the CLI output and all the MI side was only informed that the inferior had terminated? If so, that is a question for GDB folk I guess? (But I know you do a lot of stuff on GDB, so perhaps I am misunderstanding the issue?)

[GitMensch]

Yes.

If so, that is a question for GDB folk I guess?

Possibly both "GDB folk" and "debug adapter".

The issue from the debug adapter site is that cli output is not handled if "openGdbConsole": false is set, but should. Other extensions will then show the output in the debug console (detailed when verbose, otherwise only the actual stdout and stderr/undefined messages - the later is currently missing in the extension and not shown in the log at all).

But yes: there should be a MI message and rechecking shows - there isn't one. I guess I'll need to build GDB 13 (or at least the last release 12) and recheck there, and report it otherwise.

[jonahgraham]

Thanks for the clarification. Let me see what I can do about the "openGdbConsole": false case.

[jonahgraham]

Can you send the DAP + MI trace when "openGdbConsole": false? Alternatively how to make such a broken executable that you described in OP?

If I do the simple case of passing in an invalid program I get an expected pop-up:

[jonahgraham]

The screenshot above has a testcase to verify it:

https://github.com/eclipse-cdt-cloud/cdt-gdb-adapter/blob/49a568340bffe56990806b8feaa1e773cbecd843/src/integration-tests/launch.spec.ts#L44

I will have a read through the code to see why other error messages might be muted.

[GitMensch]

how to make such a broken executable that you described in OP?

• create libsome with exported function "a"
• create libsomeB with exported function "b"
• create a.out linking against libsome for function "a"
• debug a.out - all is fine
• rename libsomeB to libsomeA
• debug a.out - see the error

The "common" real-world example is a library that was linked with version 123 but used with version 120.

[GitMensch]

The screenshot above has a testcase to verify it

That works because there is an async result record for the "file-exec-and-symbols" request (output from another client, but identical here):

{"token":2,"outOfBandRecord":[],"resultRecords":{"resultClass":"error","results":[["msg","/tmp/not/there: No such file or directory."]]}}

(note: that's a local gdb, not gdbserver with "No such file or directory.", so the comments in the referenced code are at least misleading)

if a linked shared library has a mismatch you get:

{"token":2,"outOfBandRecord":[],"resultRecords":{"resultClass":"done","results":[]}}

And also a positive result for exec-run and only after both an stderr message (not a failure), likely from the dynamic link loader. The only "direct" result GDB sends is a console output with the "Inferior ... exited", followed by notify events thread-exited + thread-group-exited, followed by "stopped" return.

The code you've linked is likely "finished" there already.

[jonahgraham]

See #241 for what I created as you outlined in https://github.com/eclipse-cdt-cloud/cdt-gdb-adapter/issues/239#issuecomment-1411173434

[jonahgraham]

The test case I added in #241 sends the error to the inferior's stderr, so it is completely lost by cdt-gdb-adapter, but would be improved by having #161 fixed properly.

For now with no proper inferior, the stderr of the inferior disappear to nothing as the spawned process's stderr is never read:

https://github.com/eclipse-cdt-cloud/cdt-gdb-adapter/blob/c653a9afaecf2063501ba02d0f438eea6925f468/src/GDBBackend.ts#L81-L87

[jonahgraham]

In the immediate term I am going to start capturing stderr and returning that to the client.

[jonahgraham]

In the immediate term I am going to start capturing stderr and returning that to the client.

With the stderr captured and sent as OutputEvent this issue is now resolved, however somewhat unsatisfactorily as buffering, and intermixing of outputs with gdb itself, means that it is brittle.

161 will fix this in a better way.

[GitMensch]

Well done. As there's no way to update the built-in extension (which isn't rebuild and ci-published as vsix either) I can't test this now. To make this complete: would you mind sharing the output when starting this with the "wrong" libsome in the debugger, both with and without verbose mode enabled?
