os/exec: only use cachedLookExtensions if Cmd.Path is unmodified

2024-07-07T16:40:57Z

Caching the invocation of lookExtensions on an absolute path in Command and reusing the cached result in Start is only viable if Cmd.Path isn't set to a different value after Command returns. For #66586. Fixes #68314.

os/exec: on Windows look for extensions in Run if not already done

2024-06-07T20:13:53Z

CL 512155 fixed #36768, but introduced #62596. CL 527820 fixed #62596, but meant that the code failed to look up file extensions on Windows for a relative path. This CL fixes that problem by recording whether it has already looked up file extensions. This does mean that if Path is set manually then we do not update it with file extensions, as doing that would be racy.

Revert "os/exec: avoid calling LookPath in cmd.Start for resolved paths"

2023-09-12T00:57:26Z

This reverts CL 512155. Reason for revert: CL 512155 introduced a race in that it caused cmd.Start to set cmd.Path. Previously it was fine if code looked at cmd.Path in one goroutine while calling cmd.Start in a different goroutine. A test case for this race is in CL 527495.
