Junio C Hamano 3e1629f5a6 archive-tar.c: squelch a type mismatch warning
On some systems, giving a value of type time_t to printf "%lo" that
expects an unsigned long would give a type mismatch warning.

Brandon Casey f285a2d7ed Replace calls to strbuf_init(&foo, 0) with STRBUF_INIT initializer
Many call sites use strbuf_init(&foo, 0) to initialize local
strbuf variable "foo" which has not been accessed since its
declaration. These can be replaced with a static initialization
using the STRBUF_INIT macro which is just as readable, saves a
function call, and takes up fewer lines.

René Scharfe 562e25abea archive: centralize archive entry writing
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.

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.

Add a pointer parameter to read_tree_recursive(), which is passed to the

Johannes Schindelin ef90d6d420 Provide git_config with a callback-data parameter
git_config() only had a function parameter, but no callback data
parameter.  This assumes that all callback functions only modify
global variables.

With this patch, every callback gets a void * parameter, and it is hoped
that this will help the libification effort.

René Scharfe ac7fa2776c git-archive: ignore prefix when checking file attribute
Ulrik Sverdrup noticed that git-archive doesn't correctly apply the attribute
export-subst when the option --prefix is given, too.

When it checked if a file has the attribute turned on, git-archive would try
to look up the full path -- including the prefix -- in .gitattributes.  That's
wrong, as the prefix doesn't need to have any relation to any existing
directories, tracked or not.

This patch makes git-archive ignore the prefix when looking up if value of the
attribute export-subst for a file.

Pierre Habouzit f1696ee398 Strbuf API extensions and fixes.
* Add strbuf_rtrim to remove trailing spaces.
  * Add strbuf_insert to insert data at a given position.
  * Off-by one fix in strbuf_addf: strbuf_avail() does not counts the final
    \0 so the overflow test for snprintf is the strict comparison. This is
    not critical as the growth mechanism chosen will always allocate _more_
    memory than asked, so the second test will not fail. It's some kind of
    miracle though.
  * Add size extension hints for strbuf_init and strbuf_read. If 0, default
    applies, else:
      + initial buffer has the given size for strbuf_init.
      + first growth checks it has at least this size rather than the
        default 8192.

Pierre Habouzit 7a604f16b7 Simplify strbuf uses in archive-tar.c using strbuf API
This is just cleaner way to deal with strbufs, using its API rather than
reinventing it in the module (e.g. strbuf_append_string is just the plain
strbuf_addstr function, and it was used to perform what strbuf_addch does
anyways).

Pierre Habouzit b449f4cfc9 Rework strbuf API and semantics.
The gory details are explained in strbuf.h. The change of semantics this
patch enforces is that the embeded buffer has always a '\0' character after
its last byte, to always make it a C-string. The offs-by-one changes are all
related to that very change.

  A strbuf can be used to store byte arrays, or as an extended string
library. The `buf' member can be passed to any C legacy string function,
because strbuf operations always ensure there is a terminating \0 at the end
of the buffer, not accounted in the `len' field of the structure.

  A strbuf can be used to generate a string/buffer whose final size is not
really known, and then "strbuf_detach" can be used to get the built buffer,
and keep the wrapping "strbuf" structure usable for further work again.

  Other interesting feature: strbuf_grow(sb, size) ensure that there is
enough allocated space in `sb' to put `size' new octets of data in the
buffer. It helps avoiding reallocating data for nothing when the problem the
strbuf helps to solve has a known typical size.

René Scharfe 8460b2fcd4 archive: specfile support (--pretty=format: in archive files)
Add support for a new attribute, specfile.  Files marked as being
specfiles are expanded by git-archive when they are written to an
archive.  It has no effect on worktree files.  The same placeholders
as those for the option --pretty=format: of git-log et al. can be
used.

The attribute is useful for creating auto-updating specfiles.  It is
limited by the underlying function format_commit_message(), though.
E.g. currently there is no placeholder for git-describe like output,
and expanded specfiles can't contain NUL bytes.  That can be fixed
in format_commit_message() later and will then benefit users of
git-log, too.

René Scharfe 5e6cfc80e2 git-archive: convert archive entries like checkouts do
As noted by Johan Herland, git-archive is a kind of checkout and needs
to apply any checkout filters that might be configured.

This patch adds the convenience function convert_sha1_file which returns
a buffer containing the object's contents, after converting, if necessary
(i.e. it's a combination of read_sha1_file and convert_to_working_tree).
Direct calls to read_sha1_file in git-archive are then replaced by calls
to convert_sha1_file.

Since convert_sha1_file expects its path argument to be NUL-terminated --
a convention it inherits from convert_to_working_tree -- the patch also
changes the path handling in archive-tar.c to always NUL-terminate the
string.  It used to solely rely on the len field of struct strbuf before.

archive-zip.c already NUL-terminates the path and thus needs no such
change.

Nicolas Pitre 21666f1aae convert object type handling from a string to a number
We currently have two parallel notation for dealing with object types
in the code: a string and a numerical value.  One of them is obviously
redundent, and the most used one requires more stack space and a bunch
of strcmp() all over the place.

This is an initial step for the removal of the version using a char array
found in object reading code paths.  The patch is unfortunately large but
there is no sane way to split it in smaller parts without breaking the
system.

René Scharfe f08b3b0e2e Set default "tar" umask to 002 and owner.group to root.root
In order to make the generated tar files more friendly to users who
extract them as root using GNU tar and its implied -p option, change
the default umask to 002 and change the owner name and group name to
root.  This ensures that a) the extracted files and directories are
not world-writable and b) that they belong to user and group root.

Before they would have been assigned to a user and/or group named
git if it existed.  This also answers the question in the removed
comment: uid=0, gid=0, uname=root, gname=root is exactly what we
want.

Normal users who let tar apply their umask while extracting are
only affected if their umask allowed the world to change their
files (e.g. a umask of zero).  This case is so unlikely and strange
that we don't need to support it.

Junio C Hamano 85023577a8 simplify inclusion of system header files.
This is a mechanical clean-up of the way *.c files include
system header files.

 (1) sources under compat/, platform sha-1 implementations, and
     xdelta code are exempt from the following rules;

 (2) the first #include must be "git-compat-util.h" or one of
     our own header file that includes it first (e.g. config.h,
     builtin.h, pkt-line.h);

 (3) system headers that are included in "git-compat-util.h"
     need not be included in individual C source files.

 (4) "git-compat-util.h" does not have to include subsystem
     specific header files (e.g. expat.h).
