Junio C Hamano [Thu, 6 Oct 2011 00:23:20 +0000 (17:23 -0700)]
commit: teach --gpg-sign option

This uses the gpg-interface.[ch] to allow signing the commit, i.e.

    $ git commit --gpg-sign -m foo
    You need a passphrase to unlock the secret key for
    user: "Junio C Hamano <gitster@pobox.com>"
    4096-bit RSA key, ID 96AFE6CB, created 2011-10-03 (main key ID 713660A7)

    [master 8457d13] foo
     1 files changed, 1 insertions(+), 0 deletions(-)

The lines of GPG detached signature are placed in a new multi-line header
field, instead of tucking the signature block at the end of the commit log
message text (similar to how signed tag is done), for multiple reasons:

 - The signature won't clutter output from "git log" and friends if it is
   in the extra header. If we place it at the end of the log message, we
   would need to teach "git log" and friends to strip the signature block
   with an option.

 - Teaching new versions of "git log" and "gitk" to optionally verify and
   show signatures is cleaner if we structurally know where the signature
   block is (instead of scanning in the commit log message).

 - The signature needs to be stripped upon various commit rewriting
   operations, e.g. rebase, filter-branch, etc. They all already ignore
   unknown headers, but if we place signature in the log message, all of
   these tools (and third-party tools) also need to learn how a signature
   block would look like.

 - When we added the optional encoding header, all the tools (both in tree
   and third-party) that acts on the raw commit object should have been
   fixed to ignore headers they do not understand, so it is not like that
   new header would be more likely to break than extra text in the commit.

A commit made with the above sample sequence would look like this:

    $ git cat-file commit HEAD
    tree 3cd71d90e3db4136e5260ab54599791c4f883b9d

Support sizes >=2G in various config options accepting 'g' sizes.

The config options core.packedGitWindowSize, core.packedGitLimit,
core.deltaBaseCacheLimit, core.bigFileThreshold, pack.windowMemory and
pack.packSizeLimit all claim to support suffixes up to and including
'g'.  This implies that they should accept sizes >=2G on 64-bit
systems: certainly, specifying a size of 3g should not silently be
translated to zero or transformed into a large negative value due to
integer overflow.  However, due to use of git_config_int() rather than
git_config_ulong(), that is exactly what happens:

% git config core.bigFileThreshold 2g
% git gc --aggressive # with extra debugging code to print out
                      # core.bigfilethreshold after parsing
bigfilethreshold: -2147483648
[...]

This is probably irrelevant for core.deltaBaseCacheLimit, but is
problematic for the other values.  (It is particularly problematic for
core.packedGitLimit, which can't even be set to its default value in
the config file due to this bug.)

This fixes things for 32-bit platforms as well.  They get the usual bad
config error if an overlarge value is specified, e.g.:

fatal: bad config value for 'core.bigfilethreshold' in /home/nix/.gitconfig

This is detected in all cases, even if the 32-bit platform has no size
larger than 'long'.  For signed integral configuration values, we also
detect the case where the value is too large for the signed type but
not the unsigned type.

"verify-tag" (aka "tag -v") used to save the whole tag contents as if it
is a detached signature, and fed gpg the payload part of the tag. It
relied on gpg to fail when the given tag is not signed but just is

http: don't always prompt for password

When a username is already specified at the beginning of any HTTP
transaction (e.g. "git push https://user@hosting.example.com/project.git"
or "git ls-remote https://user@hosting.example.com/project.git"), the code
interactively asks for a password before calling into the libcurl library.
It is very likely that the reason why user included the username in the
URL is because the user knows that it would require authentication to
access the resource. Asking for the password upfront would save one
roundtrip to get a 401 response, getting the password and then retrying
the request. This is a reasonable optimization.

HOWEVER.

This is done even when $HOME/.netrc might have a corresponding entry to
access the site, or the site does not require authentication to access the
resource after all. But neither condition can be determined until we call
into libcurl library (we do not read and parse $HOME/.netrc ourselves). In
these cases, the user is forced to respond to the password prompt, only to
give a password that is not used in the HTTP transaction. If the password
is in $HOME/.netrc, an empty input would later let the libcurl layer to
pick up the password from there, and if the resource does not require
authentication, any input would be taken and then discarded without
getting used. It is wasteful to ask this unused information to the end
user.

Reduce the confusion by not trying to optimize for this case and always
incur roundtrip penalty. An alternative might be to document this and keep
this round-trip optimization as-is.

it turns things around and says what it wants to achieve in a more direct

#if mingw32
        #include "compat/mingw.h"
#elif msvc
        #include "compat/msvc.h"
#else
        ... all the others ...

gitweb: Add a feature to show side-by-side diff

This commits adds to support for showing "side-by-side" style diff.
Currently you have to hand-craft the URL; navigation for selecting
diff style is to be added in the next commit.

The diff output in unified format from "git diff-tree" is reorganized to
side-by-side style chunk by chunk with format_sidebyside_diff_chunk().
This reorganization requires knowledge about diff line classification,
so format_diff_line() was renamed to process_diff_line(), and changed to
return tuple (list) consisting of class of diff line and of
HTML-formatted (but not wrapped in <div class="diff ...">...</div>) diff
line.  Wrapping is now done by caller, i.e. git_patchset_body().

Gitweb uses float+margin CSS-based layout for "side by side" diff.

You can specify style of diff with "ds" ('diff_style') query
parameter.  Currently supported values are 'inline' and 'sidebyside';
the default is 'inline'.

Another solution would be to use "opt" ('extra_options') for that...
though current use of it in gitweb seems to suggest that "opt" is more
about passing extra options to underlying git commands, and "git diff"
doesn't support '--side-by-side' like GNU diff does, (yet?).
