Jakub Narebski 69a9b41c15 gitweb cleanup: Move @diff_opts declaration earlier
Move @diff_opts declaration earlier, so that all gitweb options are
together (and not separated by %feature hash and some subroutines),
with the exception of $GITWEB_CONFIG which must be after all option
variables including %feature hash.

While at it, in the moved comment, note that diff option '-C' implies
'-M', instead of suggesting that '-M', '-C' is required.

Matt McCutchen c956395e2b gitweb: make "No commits" in project list gray, not bold green
A missing return statement in git_get_last_activity made gitweb think
a project with no commits was in age class "age0", so the "No commits"
appeared in bold green, which was ridiculous.  I added the return so
those projects get "noage" and added a block to gitweb.css to format
the "No commits" text gray.

Matthias Lederhofer 9a7d941056 gitweb: change filename/directory name of snapshots
/.git or .git is removed from the project name and the
basename of the remaining path is used as the beginning of
the filename and as the directory in the archive.

The regexp will actually not strip off /.git or .git if there
wouldn't be anything left after removing it.

Currently the full project name is used as directory in the
archive and the basename is used as filename.  For example a
repository named foo/bar/.git will have a archive named
.git-<version>.* and extract to foo/bar/.git.  With this patch
the file is named bar-<version>.* and extracts to bar.

Jakub Narebski cd030c3a70 gitweb: '--cc' for merges in 'commitdiff' view
Allow choosing between '-c' (combined diff) and '--cc' (compact
combined) diff format in 'commitdiff' view for merge (multiparent)
commits.  Default is now '--cc'.

In the bottom part of navigation bar there is link allowing to change
diff format: "combined" for '-c' (when using '--cc') and "compact" for
'--cc' (when using '-c'), just on the right of "raw" link to
'commitdiff_plain" view.

About patchset part of diff --cc output: the difftree (whatchanged
table) has "patch" links to anchors to individual patches (on the same
page). The --cc option further compresses the patch output by
omitting some hunks; when this optimization makes all hunks disappear,
the patch is not shown (like in any other "empty diff" case). But the
fact that patch has been simplified out is not reflected in the raw
(difftree) part of diff output; the raw part is the same for '-c' and
'--cc' options. As correcting difftree is rather out of the question,
as it would require scanning patchset part before writing out
difftree, we add "Simple merge" empty diffs as a place to have anchor
to in place of those simplified out and removed patches.

Jakub Narebski deaa01a9f5 gitweb: Create special from-file/to-file header for combined diff

combined diff (for a merge commit), which looks like:

  --- a/git-gui/git-gui.sh
  +++ b/_git-gui/git-gui.sh_

(where _link_ denotes [hidden] hyperlink), create from-file(n)/to-file

  --- 1/_git-gui/git-gui.sh_
  --- 2/_git-gui.sh_

Test it on one of merge commits involving rename, e.g.

Jakub Narebski 90921740bd gitweb: Split git_patchset_body into separate subroutines
This commit makes git_patchset_body easier to read, and reduces level of
nesting and indent level. It adds more lines that it removes because of
extra parameter passing in subroutines, and subroutine calls in
git_patchset_body. Also because there are few added comments.

Below there are descriptions of all split-off subroutines:

Separate formatting "git diff" header into format_git_diff_header_line.
While at it fix it so it always escapes pathname. It would be even more
useful if we decide to use `--cc' for merges, and need to generate by
hand empty patches for anchors.

Separate formatting extended (git) diff header lines into
format_extended_diff_header_line. This one is copied without changes.

Separate formatting two-lines from-file/to-file diff header into
format_diff_from_to_header subroutine. While at it fix it so it always
escapes pathname. Beware calling convention: it takes _two_ lines.

Separate generating %from and %to hashes (with info used among others to
generate hyperlinks) into parse_from_to_diffinfo subroutine. This one is
copied without changes.

Separate checking if file was deleted (and among others therefore does
not have link to the result file) into is_deleted subroutine. This would
allow us to easily change the algotithm to find if file is_deleted in
the result.

Jakub Narebski 47598d7a49 gitweb: Provide links to commitdiff to each parent in 'commitdiff' view
Since commit-fb1dde4a we show combined diff for merges in 'commitdiff'
view, and since commit-208ecb2e also in 'commit' view. Sometimes
though one would want to see diff to one of merge commit parents. It
is easy in 'commit' view: in the commit header part there are "diff"
links for each of parent header. This commit adds such links also for
'commitdiff' view.

Add to difftree / whatchanged table row with "1", "2", ... links to
'commitdiff' view for diff with n-th parent for merge commits, as a
table header.  This is visible only in 'comitdiff' view, and only for
a merge commit (comit with more than one parent).

To save space links are shown as "n", where "n" is number of a parent,
and not as for example shortened (to 7 characters) sha1 of a parent
commit.  To make it easier to discover what links is for, each link
has 'title' attribute explaining the link.

Note that one would need to remember that difftree table in 'commit'
view has one less column (it doesn't have "patch" link column), if one
would want to add such table header also in 'commit' view.

Example output:
                          1       2       3

Petr Baudis 63fcbe00a6 gitweb: Do not use absolute font sizes
Avoid specifying font sizes in pixels, since that is just pure evil.
Pointed out by Chris Riddoch.

Note that this is pretty much just a proposal; I didn't test if everything
fits perfectly right, but things seem to be pretty much okay. repo.or.cz
uses it now as a test drive - if you find any visual quirks, please point
them out, with a patch if possible since I'm total CSS noob and debugging
CSS is an extremely painful experience for me.

Note that this patch actually does change visual look of gitweb in Firefox
with my resolution and default settings - everything is bigger and I can't
explain the joy of actually seeing gitweb text that is in _readable_ size;
also, my horizontal screen real estate feels better used now. But judging
from the look of most modern webpages on the 'net, most people prefer
reading the web with strained eyes and/or a magnifying glass (I wonder what
species of scientists should look into this mystifying phenomenon) - so,
please tell us what you think.

Maybe we might want to get rid of absolute sizes other than font sizes in
the CSS file too in the long term.

Gerrit Pape 7f9778b19b gitweb: choose appropriate view for file type if a= parameter missing
gitweb URLs use the a= parameter for the view to use on the given path, such
as "blob" or "tree".  Currently, if a gitweb URL omits the a= parameter,
gitweb just shows the top-level repository summary, regardless of the path
given.  gitweb could instead choose an appropriate view based on the file
type: blob for blobs (files), tree for trees (directories), and summary if
no path given (the URL included no f= parameter, or an empty f= parameter).

Apart from making gitweb more robust and supporting URL editing more easily,
this change would aid the creation of shortcuts to git repositories using
simple substitution, such as:
http://example.org/git/?p=path/to/repo.git;hb=HEAD;f=%s

With this patch, if given the hash through the h= parameter, or the hash
base (hb=) and a filename (f=), gitweb uses cat-file -t to automatically set
the a= parameter.

Jakub Narebski e72c0eaf9b gitweb: Add combined diff support to git_patchset_body
Calling convention for combined diff similar to the one for
git_difftree_body subroutine: difftree info (first parameter) must be
result of calling git-diff-tree with -c/--cc option, and all parents
of a commit must be passed as last parameters. See also description in
  "gitweb: Add combined diff support to git_difftree_body"

This ability is not used yet.

Generating "src" file name for renames in combined diff was separated
into fill_from_file_info subroutine; git_difftree_body was modified to
use it. Currently git_difftree_body and git_patchset_body fills this
info separately.

The from-file line in two-line from-file/to-file header is not
hyperlinked: there can be more than one "from"/"src" file. This
differs from HTML output of ordinary (not combined) diff.

format_diff_line subroutine needs extra $from/$to parameters to format
combined diff patch line correctly.

Jakub Narebski ed224deac9 gitweb: Add combined diff support to git_difftree_body
You have to pass all parents as final parameters of git_difftree_body
subroutine; the number of parents of a diff must be equal to the
number derived from parsing git-diff-tree output, raw combined diff
for git_difftree_body to display combined diff correctly (but it is
not checked).

Currently the possibility of displaying diffree of combined diff is
not used in gitweb code; git_difftree_body is always caled for
ordinary diff, and with only one parent.

Description of output for combined diff:
----------------------------------------

The difftree table for combined diff starts with a cell with pathname
of changed blob (changed file), which if possible is hidden link
(class="list") to the 'blob' view of final version (if it exists),
like for difftree for ordinary diff. If file was deleted in the final
commit then filename is not hyperlinked.

There is no cell with single file status (new, deleted, mode change,
rename), as for combined diff as there is no single status: different
parents might have different status.

If git_difftree_body was called from git_commitdiff (for 'commitdiff'
action) there is inner link to anchor to appropriate fragment (patch)
in patchset body; the "patch" link does not replace "diff" link like
for ordinary diff.

Each of "diff" links is in separate cell, contrary to output for
ordinary diff in which all links are (at least for now) in a single
cell.

For each parent, if file was not present we leave cell empty. If file
was deleted in the result, we provide link to 'blob' view. Otherwise
we provide link to 'commitdiff' view, even if patch (diff) consist
only of extended diff header, and contents is not changed (pure
rename, pure mode change). The only difference is that link to
"blobdiff" view with no contents change is with 'nochange' class.

At last, there is provided link to current version of file as "blob"
link, if the file was not deleted in the result, and lik to history of
a file, if there exists one. (The link to file history might be
confused, at least for now, by renames.)

Note that git-diff-tree raw output dor combined diff does not provide
filename before change for renames and copies; we use
git_get_path_by_hash to get "src" filename for renames (this means
additional call to git-ls-tree for a _whole_ tree).

Jakub Narebski 78bc403aaf gitweb: Add parsing of raw combined diff format to parse_difftree_raw_line
Add parsing line of raw combined diff ("git diff-tree -c/-cc" output)
as described in section "diff format for merges" in diff-format.txt
to parse_difftree_raw_line subroutine.

Returned hash (or hashref) has for combined diff 'nparents' key which
holds number of parents in a merge. At keys 'from_mode' and 'from_id'
there are arrayrefs holding modes and ids, respectively. There is no
'similarity' value, and there is only 'to_file' value and no
'from_file' value.

Frank Lichtenheld b06dcf8cb8 gitweb: Allow configuring the default projects order and add order 'none'
Introduce new configuration variable $default_projects_order
that can be used to specify the default order of projects on
the index page if no 'o' parameter is given.

Allow a new value 'none' for order that will cause the projects
to be in the order we learned about them. In case of reading the
list of projects from a file, this should be the order as they are
listed in the file. In case of reading the list of projects from
a directory this will probably give random results depending on the
filesystem in use.

Jakub Narebski 957d6ea78f gitweb: Fix bug in "blobdiff" view for split (e.g. file to symlink) patches
git_patchset_body needs patch generated with --full-index option to
detect split patches, meaning two patches which corresponds to single
difftree (raw diff) entry.  An example of such situation is changing
type (mode) of a file, e.g. from plain file to symbolic link.

Add, in git_blobdiff, --full-index option to patch generating git diff
invocation, for the 'html' format output ("blobdiff" view).

"blobdiff_plain" still uses shortened sha1 in the extended git diff
header "index <hash>..<hash>[ <mode>]" line.

Jakub Narebski 5ae917acdf gitweb: Support comparing blobs (files) with different names
Fix the bug that caused "blobdiff" view called with new style URI
for a rename with change diff to be show as new (added) file diff.

New style URI for "blobdiff" for rename means with $hash_base ('hb') and
$hash_parent_base ('hpb') paramaters denoting tree-ish (usually commit)
of a blobs being compared, together with both $file_name ('f') and
$file_parent ('fp') parameters.

It is done by adding $file_parent ('fp') to the path limiter, meaning
that diff command becomes:

	git diff-tree [options] hpb hb -- fp f

Other option would be finding hash of a blob using git_get_hash_by_path
subroutine and comparing blobs using git-diff, or using extended SHA-1
syntax and compare blobs using git-diff:

	git diff [options] hpb:fp hp:f
