René Scharfe d23309733a introduce hex2chr() for converting two hexadecimal digits to a character
Add and use a helper function that decodes the char value of two
hexadecimal digits.  It returns a negative number on error, avoids
running over the end of the given string and doesn't shift negative
values.

Jeff King 00b6c178c3 use strbuf_complete to conditionally append slash
When working with paths in strbufs, we frequently want to
ensure that a directory contains a trailing slash before
appending to it. We can shorten this code (and make the
intent more obvious) by calling strbuf_complete.

Most of these cases are trivially identical conversions, but
there are two things to note:

  - in a few cases we did not check that the strbuf is
    non-empty (which would lead to an out-of-bounds memory
    access). These were generally not triggerable in
    practice, either from earlier assertions, or typically
    because we would have just fed the strbuf to opendir(),
    which would choke on an empty path.

  - in a few cases we indexed the buffer with "original_len"
    or similar, rather than the current sb->len, and it is
    not immediately obvious from the diff that they are the
    same. In all of these cases, I manually verified that
    the strbuf does not change between the assignment and
    the strbuf_complete call.

This does not convert cases which look like:

  if (sb->len && !is_dir_sep(sb->buf[sb->len - 1]))
	  strbuf_addch(sb, '/');

as those are obviously semantically different. Some of these
cases arguably should be doing that, but that is out of
scope for this change, which aims purely for cleanup with no
behavior change (and at least it will make such sites easier
to find and examine in the future, as we can grep for
strbuf_complete).

Jeff King 66c8448543 url: decode buffers that are not NUL-terminated
The url_decode function needs only minor tweaks to handle
arbitrary buffers. Let's do those tweaks, which cleans up an
unreadable mess of temporary strings in http.c.

Stephen Boyd c2e86addb8 Fix sparse warnings
Fix warnings from 'make check'.

 - These files don't include 'builtin.h' causing sparse to complain that
   cmd_* isn't declared:

   builtin/clone.c:364, builtin/fetch-pack.c:797,
   builtin/fmt-merge-msg.c:34, builtin/hash-object.c:78,

   builtin/remote-fd.c:53, builtin/reset.c:236, builtin/send-pack.c:384,
   builtin/unpack-file.c:25, builtin/var.c:75

 - These files have symbols which should be marked static since they're
   only file scope:

   submodule.c:12, diff.c:631, replace_object.c:92, submodule.c:13,

   url.c:129, url.c:136, thread-utils.c:21, thread-utils.c:48

 - These files redeclare symbols to be different types:

   builtin/index-pack.c:210, parse-options.c:564, parse-options.c:571,
   usage.c:49, usage.c:58, usage.c:63, usage.c:72

 - These files use a literal integer 0 when they really should use a NULL
   pointer:

   daemon.c:663, fast-import.c:2942, imap-send.c:1072, notes-merge.c:362

While we're in the area, clean up some unused #includes in builtin files
(mostly exec_cmd.h).

Thomas Rast 730220de8b Do not unquote + into ' ' in URLs
Since 9d2e942 (decode file:// and ssh:// URLs, 2010-05-23) the URL
logic unquotes escaped URLs.  For the %2B type of escape, this is
conformant with RFC 2396.  However, it also unquotes + into a space
character, which is only appropriate for the query strings in HTTP.
This notably broke fetching from the gtk+ repository.

We cannot just remove the corresponding code since the same
url_decode_internal() is also used by the HTTP backend to decode query
parameters.  Introduce a new argument that controls whether the +
decoding happens, and use it only in the (client-side) url_decode().

Junio C Hamano ce83eda155 url.c: "<scheme>://" part at the beginning should not be URL decoded
When using the protocol git+ssh:// for example we do not want to
decode the '+' as a space. The url decoding must take place only
for the server name and parameters.

This fixes a regression introduced in 9d2e942.
