Fixes#123442

The tracee hit the 5s timeout on the jitstress lane. Given that jitstress lanes are known to be slow, I'm expecting non-jitstress lanes to still complete quickly despite the longer timeout. Also added logs to 1) indicate whether the Tracee's EventSource was enabled and 2) reveal which .NET processes record-trace detected and sent an IPC command.

Below is an example output with these in effect
record-trace emits Enabled .NET events for process: pid=13803

The CI runs logs from record-trace are far more noisy than my local ones, looking into refining.

…lure
Route record-trace diagnostic logs to a temporary file via --log-path
instead of --log-mode console to keep test console output clean. On test
failure, upload the log file alongside the .nettrace to Helix artifacts
for post-mortem analysis.
Generalize UploadTraceFileFromHelix into UploadArtifactsFromHelixOnFailure
to support uploading multiple artifacts, and ensure the record-trace log
is uploaded on all failure paths including when the trace file itself is
missing.

The logs were noisy from record-trace failing to connect to some alternate diagnostic ports for every mmap event. I created an issue microsoft/one-collect#236, but it might be as designed.
Since its unclear how noisy the logs are, routing them into a temporary file instead of to console, and will only upload on failure.

For some reason the request to rerun runtime-coreclr jitstress2-jitstressregs seems to have been ignored. EIther way, that pipeline had passed in jkotas' invocation, which tested the timeout bump. And in the normal coreclr tests, the output is no longer flooded with logs.

Fixes#123442
The tracee hit the 5s timeout on the jitstress lane. Given that jitstress lanes are known to be slow, I'm expecting non-jitstress lanes to still complete quickly despite the longer timeout. Also added logs to 1) indicate whether the Tracee's EventSource was enabled and 2) reveal which .NET processes record-trace detected and sent an IPC command.
Below is an example output with these in effect

Route record-trace diagnostic logs to a temporary file via --log-path
instead of --log-mode console to keep test console output clean. On test
failure, upload the log file alongside the .nettrace to Helix artifacts
for post-mortem analysis.
Generalize UploadTraceFileFromHelix into UploadArtifactsFromHelixOnFailure
to support uploading multiple artifacts, and ensure the record-trace log
is uploaded on all failure paths including when the trace file itself is
missing.

The logs were noisy from record-trace failing to connect to some alternate diagnostic ports for every mmap event. I created an issue microsoft/one-collect#236, but it might be as designed.

Since its unclear how noisy the logs are, routing them into a temporary file instead of to console, and will only upload on failure.

For some reason the request to rerun runtime-coreclr jitstress2-jitstressregs seems to have been ignored. EIther way, that pipeline had passed in jkotas' invocation, which tested the timeout bump. And in the normal coreclr tests, the output is no longer flooded with logs.

For some reason the request to rerun runtime-coreclr jitstress2-jitstressregs seems to have been ignored. EIther way, that pipeline had passed in jkotas' invocation, which tested the timeout bump. And in the normal coreclr tests, the output is no longer flooded with logs.

Fixes#123442
The tracee hit the 5s timeout on the jitstress lane. Given that jitstress lanes are known to be slow, I'm expecting non-jitstress lanes to still complete quickly despite the longer timeout. Also added logs to 1) indicate whether the Tracee's EventSource was enabled and 2) reveal which .NET processes record-trace detected and sent an IPC command.
Below is an example output with these in effect

record-trace emits Enabled .NET events for process: pid=13803

…lure
Route record-trace diagnostic logs to a temporary file via --log-path
instead of --log-mode console to keep test console output clean. On test
failure, upload the log file alongside the .nettrace to Helix artifacts
for post-mortem analysis.
Generalize UploadTraceFileFromHelix into UploadArtifactsFromHelixOnFailure
to support uploading multiple artifacts, and ensure the record-trace log
is uploaded on all failure paths including when the trace file itself is
missing.

The logs were noisy from record-trace failing to connect to some alternate diagnostic ports for every mmap event. I created an issue microsoft/one-collect#236, but it might be as designed.

Since its unclear how noisy the logs are, routing them into a temporary file instead of to console, and will only upload on failure.
