2016-06-27Merge branch 'cc/apply-introduce-state'Libravatar Junio C Hamano1-609/+820
The "git apply" standalone program is being libified; this is the first step to move many state variables into a structure that can be explicitly (re)initialized to make the machinery callable more than once. The next step that moves some remaining state variables into the structure and turns die()s into an error return that propagates up to the caller is not queued yet but in flight. It would be good to review the above first and give the remainder of the series a solid base to build on. * cc/apply-introduce-state: (50 commits) builtin/apply: remove misleading comment on lock_file field builtin/apply: move 'newfd' global into 'struct apply_state' builtin/apply: add 'lock_file' pointer into 'struct apply_state' builtin/apply: move applying patches into apply_all_patches() builtin/apply: move 'state' check into check_apply_state() builtin/apply: move 'symlink_changes' global into 'struct apply_state' builtin/apply: move 'fn_table' global into 'struct apply_state' builtin/apply: move 'state_linenr' global into 'struct apply_state' builtin/apply: move 'max_change' and 'max_len' into 'struct apply_state' builtin/apply: move 'ws_ignore_action' into 'struct apply_state' builtin/apply: move 'ws_error_action' into 'struct apply_state' builtin/apply: move 'applied_after_fixing_ws' into 'struct apply_state' builtin/apply: move 'squelch_whitespace_errors' into 'struct apply_state' builtin/apply: remove whitespace_option arg from set_default_whitespace_mode() builtin/apply: move 'whitespace_option' into 'struct apply_state' builtin/apply: move 'whitespace_error' global into 'struct apply_state' builtin/apply: move 'root' global into 'struct apply_state' builtin/apply: move 'p_value_known' global into 'struct apply_state' builtin/apply: move 'p_value' global into 'struct apply_state' builtin/apply: move 'has_include' global into 'struct apply_state' ...
2016-06-06builtin/apply: remove misleading comment on lock_file fieldLibravatar Junio C Hamano1-4/+1
Just like pointer field like prefix, the piece of memory pointed at by lock_file field is not owned by the apply_state structure. It is true that the caller needs to be careful about the lifetime rule for lockfile instances, but that is none of this API's business. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-06-03builtin/apply: add 'lock_file' pointer into 'struct apply_state'Libravatar Christian Couder1-4/+15
We cannot have a 'struct lock_file' allocated on the stack, as lockfile.c keeps a linked list of all created lock_file structures. Also 'struct apply_state' users might later want the same 'struct lock_file' instance to be reused by different series of calls to the apply api. So let's add a 'struct lock_file *lock_file' pointer into 'struct apply_state' and have the user of 'struct apply_state' allocate memory for the actual 'struct lock_file' instance. Let's also add an argument to init_apply_state(), so that the caller can easily supply a pointer to the allocated instance.

2016-05-12builtin/apply: introduce 'struct apply_state' to start libifyingLibravatar Christian Couder1-38/+56
Currently commands that want to use the apply functionality have to launch a "git apply" process which can be bad for performance. Let's start libifying the apply functionality and to do that we first need to get rid of the global variables in "builtin/apply.c". This patch introduces "struct apply_state" into which all the previously global variables will be moved. A new parameter called "state" that is a pointer to the "apply_state" structure will come at the beginning of the helper functions that need it and will be passed around the call chain. To start let's move the "prefix" and "prefix_length" global variables into "struct apply_state".
