When calling cgit_print_diff() with a bad new_rev and a NULL old_rev,
checking for new_rev's parent commit will result in a null pointer
dereference. Returning on an invalid commit before dereferencing fixes
this. Spotted with clang-analyzer.

reencode() takes three arguments in the order (txt, from, to), opposed to
reencode_string, which will, like iconv, handle the arguments with from
and to swapped. Fix that (this makes reencode more intuitive).
If src and dst encoding are equivalent, don't do any encoding.
If no special encoding parameter is found within the commit, assume
UTF-8 and explicitly convert to PAGE_ENCODING. The change to reencode()
mentioned above avoids re-encoding a UTF-8 string to UTF-8, for example.

When setting virtual-root from cgitrc, care is taken to avoid trailing
slashes. But when no virtual-root setting is specified, SCRIPT_FILE
from the web server is used without similar checks. This patch fixes the

When a query ends in say %gg, (or any invalid hex) e.g.,
http://git.gnome.org/browse/gdlmm/commit/?id=%gg
convert_query_hexchar calls memmove(txt, txt+3, 0), and then returns
txt-1, so the loop in http_parse_querystring never terminates. The
solution is to make the memmove also copy the trailing NUL.

Paths that start with a period ('.') are considered hidden in the Unix world.
scan_path() should arguably not recurse into these directories by default.
This patch makes it so, and introduces the "scan-hidden-path" config variable
for overriding the new default and revert to the old behaviour (scanning _all_
directories, including hidden .directories).

When scanning a tree containing inaccessible directories (e.g. '.ssh'
directories in users' homedirs, or repos with explicitly restricted access),
scan_path() currently causes three lines of "Permissions denied" errors to be
printed to the CGI error log per inaccessible directory:
Error checking path /home/foo/.ssh: Permission denied (13)
Error checking path /home/foo/.ssh/.git: Permission denied (13)
Error opening directory /home/foo/.ssh: Permission denied (13)
This is a side-effect of calling is_git_dir(path) and
is_git_dir(fmt("%s/.git", path) _before_ we try to opendir(path).
By placing the opendir(path) before the two is_git_dir() calls, we reduce the
noise to a single line per inaccessible directory:
Error opening directory /home/foo/.ssh: Permission denied (13)

When showmsg is disabled ui-log truncates long commit subjects. This is good.
However, the same is not desirable when showmsg is enabled, since you then
end up with a truncated commit subject followed by the rest of the commit
message below.
Instead, when showmsg is enabled (and we're using all this space to display
the entire commit message, anyway), line-wrap the commit subject instead of
truncating it.

Use the existing coloring logic in Git's graph code to color the lines
between commits in the commit graph.
Whereas Git normally uses ANSI color escapes to produce colors, we here
use graph_set_column_colors() to replace those with HTML color escapes,
that embed the graph lines in <span> tags that apply the desired color
using CSS.

Teach CGit to print an ASCII art commit graph to the left of the commit
message, similar to 'git log --graph'. The graph adds extra lines (table
rows) to the log when needed to add/remove/shuffle edges in the graph.
When 'showmsg' is enabled, the graph is automatically padded to account
for the extra lines added by the commit message/notes.
This feature is controlled by a new config variable: "enable-commit-graph"
(disabled by default), and individual repos can control it by setting
"repo.enable-commit-graph".

When showmsg is enabled, ui-log (in addition to the table row containing
the details of the current commit) adds a second table row containing the
remainder of the commit message, and yet another table row containing the
commit notes (if any). The vertical margins between commit subject, commit
message and commit notes are controlled by CSS.
In preparation for the commit graph (which will be printed to the left of
the commit message/notes) we need to eliminate these vertical margins (as
they would produce ugly gaps in the commit graph) and instead achieve them
by adding newlines to the commit message/notes. Furthermore, we can no
longer print the "Notes:" header in the "Age" column, since the graph will
be drawn between the "Age" column and the "Commit message" column.
This patch therefore prepares the commit message and commit notes in a
single buffer (properly formatting the notes using the NOTES_SHOW_HEADER
and NOTES_INDENT flags to format_note()), and then prints the entire
buffer into a single table row.

When using ui-log with path limits, the listing of commits enables parent
rewriting in Git's internal log machinery. This did not work well together
with cgit_diff_commit() which is used to generate the filecount and
linecount numbers for each commit in the log view. cgit_diff_commit() would
operate without any path limits, and would therefore process the full diff
between the commits shown (which, because of parent rewriting, is not the
same as processing the diff for the commit itself). Additionally, the bottom
commit in the log view would (again, because of parent rewriting) have zero
parents, causing us to process the entire diff between the empty tree and
that commit. Since path limits were not in effect, this would (in large
projects) reports thousands of files and millions of lines changed in that
bottom commit.
This patch fixes the issue by applying the same path limit to
cgit_diff_commit() as is applied to the rest of the log view. The result is
that the filecount/linecount now only reflects the diff as it pertains to
the given path limit.
