Replace the code that calls backend specific argument parsers by a
simple flag mechanism. This reduces code size and complexity.
We can add back such a mechanism (based on incremental parse_opt(),
perhaps) when we need it. The compression level parameter, though,
is going to be shared by future compressing backends like tgz.

Add a pointer parameter to read_tree_recursive(), which is passed to the
callback function. This allows callers of read_tree_recursive() to
share data with the callback without resorting to global variables. All
current callers pass NULL.

From: René Scharfe @ 2008-07-14 19:22 UTC (permalink / raw)
To: Junio C Hamano; +Cc: Git Mailing List
Add the exported function write_archive_entries() to archive.c, which uses
the new ability of read_tree_recursive() to pass a context pointer to its
callback in order to centralize previously duplicated code.
The new callback function write_archive_entry() does the work that every
archiver backend needs to do: loading file contents, entering subdirectories,
handling file attributes, constructing the full path of the entry. All that
done, it calls the backend specific write_archive_entry_fn_t function.

Now that all file attribute handling for git archive has moved to archive.c,
we can unexport sha1_file_to_archive() and is_archive_path_ignored() even
disappears.
Add setup_archive_check(), modelled after similar functions used in the code
of other commands that support multiple file attributes.
Also remove convert_to_archive(), as it's only remaining function with
attribute handling gone was to call format_subst() if commit was not NULL,
which is now checked in sha1_file_to_archive().

Calculate the length of base and save it in a new member of struct
archiver_args. This way we don't have to compute it in each of the
format backends.
Note: parse_archive_args() guarantees that ->base won't ever be NULL.
