Fixes #13001

When C_Cpp.intelliSenseEngine is set to "disabled", the language server client is not started. Previously, cpptools.buildAndDebug.isSourceFile and cpptools.buildAndDebug.isFolderOpen context keys (which control the visibility of the "Run / Debug C/C++ File" and "Add Debug Configuration" editor action buttons) were only updated within the language server client (client.ts). Consequently, disabling IntelliSense would cause the Run/Debug shortcut buttons to never appear in the editor title bar.

This PR updates the Debugger extension initialization (Debugger/extension.ts) to track active text editor changes and keep buildAndDebugIsSourceFile and buildAndDebugIsFolderOpen up to date regardless of whether IntelliSense is enabled or disabled.

Changes

  1. Added updateBuildAndDebugSessionState and registered an onDidChangeActiveTextEditor listener in DebuggerExtension.initialize.
  2. Added unit tests in Extension/test/scenarios/SingleRootProject/tests/buildAndDebug.test.ts verifying session state updates for source files, header files, non-C/C++ files, and undefined editors.

Verification

  • Compiled with TypeScript (yarn compile) with 0 errors.
  • Ran tests via yarn test --scenario=SingleRootProject and verified all BuildAndDebug SessionState Tests pass.

The correctness fixes now look sound. One focused test-coverage gap remains for the new event-driven paths.

Prashant Kumar Rai (@8prashant) FYI, the full Run/Debug feature doesn't work since it relies on compiler info that is returned from the cpptools process, but if you have your tasks.json/launch.json already generated (with the IntelliSense engine enabled for example), then it works.

Hi Sean McManus (@sean-mcmanus), thanks for reviewing the PR and for adding the regression coverage. I have confirmed that the requested changes are included, and the latest checks are clean.

The PR is approved, but I do not have the merge permission for the upstream repository, so the Merge button is not available to me. Could you please merge PR #14719 when you have a chance?

Thanks!

* Add processFilter for remote attach process selection (#14684)

* Add processFilter for remote attach process selection

When attaching to a process on a remote target, the process always has
to be selected by hand, even though the launch configuration already
knows which executable it belongs to. A generated configuration cannot
hard-code processId either, because the pid changes on every boot and
on every restart of the service, so the picker is the only option.

Add an optional processFilter regular expression to the cppdbg attach
configuration. When set, it is matched against the label, description
and detail of the remote process list:

  exactly one match  attach to that process directly
  more than one      show the picker with only the matching entries
  no match           show the full picker, as before

All three fields are considered because the item format depends on the
transport: useExtendedRemote reports the user and the full command line
in the label, while pipeTransport reports the process name in the label
and the command line in the detail.

An invalid regular expression is reported instead of being silently
ignored.

This affects remote attach only (pipeTransport and useExtendedRemote);
local attach continues to use program-based matching.

Closes #14682

* Extract remote process filtering into a helper

Move the matching logic out of RemoteAttachPicker into a standalone
function so that it can be unit tested without a VS Code quick pick or
a live connection to a remote target.

No functional change.

* Add unit tests for processFilter matching

Cover empty and non-string filter values, matching against label,
description and detail, multiple matches, an invalid regular
expression, and a regression case ensuring missing fields are not
treated as empty strings.
