2016-09-07builtin/apply: make create_one_file() return -1 on errorLibravatar Christian Couder1-15/+21
To libify `git apply` functionality we have to signal errors to the caller instead of exit()ing. To do that in a compatible manner with the rest of the error handling in "builtin/apply.c", create_one_file() should return -1 instead of calling exit().

2016-09-07builtin/apply: make try_create_file() return -1 on errorLibravatar Christian Couder1-11/+33
To libify `git apply` functionality we have to signal errors to the caller instead of die()ing. To do that in a compatible manner with the rest of the error handling in "builtin/apply.c", try_create_file() should return -1 in case of error. Unfortunately try_create_file() currently returns -1 to signal a recoverable error. To fix that, let's make it return 1 in case of a recoverable error and -1 in case of an unrecoverable error.

To libify `git apply` functionality we have to signal errors to the caller instead of die()ing. To do that in a compatible manner with the rest of the error handling in "builtin/apply.c", gitdiff_*() functions should return -1 instead of calling die(). A previous patch made it possible for gitdiff_*() functions to return -1 in case of error. Let's take advantage of that to make gitdiff_verify_name() return -1 on error, and to have gitdiff_oldname() and gitdiff_newname() directly return what gitdiff_verify_name() returns.

2016-08-11builtin/apply: make gitdiff_*() return 1 at end of headerLibravatar Christian Couder1-3/+9
The gitdiff_*() functions that are called as p->fn() in parse_git_header() should return 1 instead of -1 in case of end of header or unrecognized input, as these are not real errors. It just instructs the parser to break out. This makes it possible for gitdiff_*() functions to return -1 in case of a real error. This will be done in a following patch.

2016-08-11builtin/apply: make apply_all_patches() return 128 or 1 on errorLibravatar Christian Couder1-11/+26
To finish libifying the apply functionality, apply_all_patches() should not die() or exit() in case of error, but return either 128 or 1, so that it gives the same exit code as when die() or exit(1) is called. This way scripts relying on the exit code don't need to be changed. While doing that we must take care that file descriptors are properly closed and, if needed, reset to a sensible value. Also, according to the lockfile API, when finished with a lockfile, one should either commit it or roll it back. This is even more important now that the same lockfile can be passed to init_apply_state() many times to be reused by series of calls to the apply lib functions.

To libify `git apply` functionality we have to signal errors to the caller instead of die()ing. As a first step in this direction, let's make apply_patch() return -1 or -128 in case of errors instead of dying. For now its only caller apply_all_patches() will exit(128) when apply_patch() return -128 and it will exit(1) when it returns -1. We exit() with code 128 because that was what die() was doing and we want to keep the distinction between exiting with code 1 and exiting with code 128.
