run-command: store an optional argv_array
All child_process structs need to point to an argv. For flexibility, we do not mandate the use of a dynamic argv_array. However, because the child_process does not own the memory, this can make memory management with a separate argv_array difficult. For example, if a function calls start_command but not finish_command, the argv memory must persist. The code needs to arrange to clean up the argv_array separately after finish_command runs. As a result, some of our code in this situation just leaks the memory. To help such cases, this patch adds a built-in argv_array to the child_process, which gets cleaned up automatically (both in finish_command and when start_command fails). Callers may use it if they choose, but can continue to use the raw argv if they wish. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
