Florian Achleitner	df7428eca4	Add argv_array_detach and argv_array_free_detached Allow detaching of ownership of the argv_array's contents and add a function to free those detached argv_arrays later. This makes it possible to use argv_array efficiently with the exiting struct child_process which only contains a member char **argv. Add to documentation.

Jeff King	fe4a0a2888	argv-array: add pop function Sometimes we build a set of similar command lines, differing only in the final arguments (e.g., "fetch --multiple"). To use argv_array for this, you have to either push the same set of elements repeatedly, or break the abstraction by manually manipulating the array's internal members. Instead, let's provide a sanctioned "pop" function to remove elements from the end. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	13 years ago
Jeff King	d15bbe1379	argv-array: add a new "pushl" method It can be convenient to push many strings in a single line (e.g., if you are initializing an array with defaults). This patch provides a convenience wrapper to allow this. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	13 years ago
Jeff King	c1189caeaf	refactor argv_array into generic code The submodule code recently grew generic code to build a dynamic argv array. Many other parts of the code can reuse this, too, so let's make it generically available. There are two enhancements not found in the original code: 1. We now handle the NULL-termination invariant properly, even when no strings have been pushed (before, you could have an empty, NULL argv). This was not a problem for the submodule code, which always pushed at least one argument, but was not sufficiently safe for generic code. 2. There is a formatted variant of the "push" function. This is a convenience function which was not needed by the submodule code, but will make it easier to port other users to the new code.
