As fn_table is cleared at the end of apply_patch(), it is not

When the apply functionality will be libified, the 'struct apply_state'
will be used by different pieces of code.
To properly initialize a 'struct apply_state', let's provide a nice
and easy to use init_apply_state() function.
Let's also provide clear_apply_state() to release memory used by
'struct apply_state' members, so that a 'struct apply_state' instance
can be easily reused without leaking memory.
Note that clear_apply_state() does nothing for now, but it will later.
While at it, let's rename 'prefix_' parameter to 'prefix'.

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".

As the value returned by gitdiff_verify_name() is put into the
same variable that is passed as a parameter to this function,
it is simpler to pass the address of the variable and have
gitdiff_verify_name() change the variable itself.
This also makes it possible to later have this function return
-1 instead of die()ing in case of error.

Minor code clean-up.
* cc/apply:
builtin/apply: free patch when parse_chunk() fails
builtin/apply: handle parse_binary() failure
apply: remove unused call to free() in gitdiff_{old,new}name()
builtin/apply: get rid of useless 'name' variable
|
|
When parse_chunk() fails it can return -1, for example
when find_header() doesn't find a patch header.
In this case it's better in apply_patch() to free the
"struct patch" that we just allocated instead of
leaking it.

In parse_binary() there is:
forward = parse_binary_hunk(&buffer, &size, &status, &used);
if (!forward && !status)
/* there has to be one hunk (forward hunk) */
return error(_("unrecognized binary patch at line %d"), linenr-1);
so parse_binary() can return -1, because that's what error() returns.
Also parse_binary_hunk() sets "status" to -1 in case of error and
parse_binary() does "if (status) return status;".
In this case parse_chunk() should not add -1 to the patchsize it computes.
It is better for future libification efforts to make it just return -1.
