Problem
When creating a Python virtual environment in a very large workspace folder (e.g., a dev folder with many subdirectories and files), the "Searching for dependencies" progress notification would run for an extended period with no way to cancel. Users were forced to either wait indefinitely or exit VS Code entirely to escape the operation.
Solution
Added cancellation support to the dependency search progress by setting
cancellable: truein thewithProgressoptions. This enables a Cancel button (X) on the progress notification, allowing users to gracefully exit the operation.Changes
Modified
src/managers/builtin/pipUtils.ts:cancellable: trueto the progress options in thegetProjectInstallablefunctionfindFilescalls, so no additional changes were neededAdded tests in
src/test/managers/builtin/pipUtils.unit.test.ts:cancellableflag is set correctlyHow Cancellation Works
token.isCancellationRequested = truefindFilesAPI calls check the token and terminate the searchCancellationErroris thrown and propagates up the call stackImpact
