* This API allows you to create a temporary object directory, advertise it to
|
||
|
* sub-processes via GIT_OBJECT_DIRECTORY and GIT_ALTERNATE_OBJECT_DIRECTORIES,
|
||
|
* and then either migrate its object into the main object directory, or remove
|
||
|
* it. The library handles unexpected signal/exit death by cleaning up the
|
||
|
* temporary directory.
|
||
|
*
|
||
|
* Example:
|
||
|
*
|
||
|
* struct tmp_objdir *t = tmp_objdir_create();
|
||
|
* if (!run_command_v_opt_cd_env(cmd, 0, NULL, tmp_objdir_env(t)) &&
|
||
|
* !tmp_objdir_migrate(t))
|
||
|
* printf("success!\n");
|
||
|
* else
|
||
|
* die("failed...tmp_objdir will clean up for us");
