[PATCH 1/4] gitweb: Add missing show '...' links change.

[Robert Fitzsimons]

Part of the patch for "gitweb: Show '...' links in "summary" view only
if there are more items" (313ce8cee665447e4476d7e8985b270346a8e5a1) is
missing.  Add it back in.

With all the tooing and frowing this part of the original patch got
lost.  I'm also resubmiting the original optimizations patches with a
few changes.

[PATCH] Small optimizations to gitweb

[Robert Fitzsimons]

Limit some of the git_cmd's so they only return the number of lines
that will be processed.  Don't recompute head hash or have_snapshot
values.

Actually, that is needed to implement checking if we have more than
the number of commits to show to add '...' at the end only if there
are some commits which we don't show. The same for heads and tags.
(On my short TODO list, but feel free to do it yourself, if you want).

So ack without the last chunk.

The counting code in git_*_body is seriously unusual to tempt
anybody who reviews the code to reduce that 17 to 16.

The caller says:

	git_shortlog_body(\@revlist, 0, 15, $refs,
	                  $cgi->a({-href => href(action=>"shortlog")}, "..."));

If it counts up, especially if it counts from zero, the loop
would usually say:

	for (i = bottom; i < end; i++)

and anybody who reads that caller would expect it to show 15
lines of output.

But the actual code does this instead:

    sub git_shortlog_body {
            # uses global variable $project
            my ($revlist, $from, $to, $refs, $extra) = @_;

            $from = 0 unless defined $from;
            $to = $#{$revlist} if (!defined $to || $#{$revlist} < $to);
            ...
            for (my $i = $from; $i <= $to; $i++) {
                    ... draw each item ...
            }
            if (defined $extra) {
                    print "<tr>\n" .
                          "<td colspan=\"4\">$extra</td>\n" .
                          "</tr>\n";
            }
    }

By the way, I wonder how that $extra is omitted when $revlist is
longer than $to; it should be a trivial fix but it seems to me
that it is always spitted out with the current code.

Well, this should be then corrected perhaps to

            my ($revlist, $begin, $end, $refs, $extra) = @_;

            $begin = 0 unless defined $from;
            $end = scalar(@$revlist) if (!defined $end || @$revlist <= $end);
            ...
            for (my $i = $begin; $i < $end; $i++) {
                    ... draw each item ...
            }

I thought that $from..$to ($from <= i <= $to) is more natural
and easier to understand than $begin..$end ($begin <= i < $end)...
guess I guessed wrong.

We should check if we want to omit $extra, either in caller or
in callee, the *_body subroutine itself.

Well, I did not say it was _wrong_, just unusual, so there is
nothing to fix.

Check?

[PATCH] gitweb: Show '...' links in "summary" view only if there are more items

[Jakub Narebski]

Show "..." links in "summary" view to shortlog, heads (if there are
any), and tags (if there are any) only if there are more items to show
than shown already.

This means that "..." link is shown below shortened shortlog if there
are more than 16 commits, "..." link below shortened heads list if
there are more than 16 heads refs (16 branches), "..." link below
shortened tags list if there are more than 16 tags.

Added some comments.

And now it is done.

Slightly tested: on my clone (copy) of git repository, which more than
16 commits, more than 16 heads (most temporary, and no longer worked on,
few tracking branches) and more than 16 heads show all "..." as it should.
Test of freshly created repository shown no "..." for commits (only one
commit), no "..." for heads (only one default head 'master'), and no
tags list (no tags at all).

By the way, I have _NOT_ applied Robert Fitzsimons patch, but they
(this patch and Robert patch) should be not in conflict if we remove
last chunk of Robert's patch (this changing --count=17 to --count=15
in git_summary).

Just removing the last chunk isn't correct, there are two slightly
different changes in that chuck.  The reduction in the max-count value
and a removal of a call to git_get_head_hash.

Here is an updated version of the patch which should apply against
master.

Junio usually puts such comments in brackets (I don't know if it is
always used, i.e. if it is some 'convention'), e.g.:

  Also perform the same "..." link logic to the forks list.

  [rf: Modified patch from Jakub to to apply cleanly to master]

or something like that. Just a nitpick.


By the way, it looks like git_get_projects_list($project) used to get
list of forks does not have any count limit option.

and if we remove that chunk, then your earlier patch would not

It needs to be 17, not 16, otherwise we never would get "...". By default
we show _16_ items, from 0 to 15 inclusive, so we must get _17_ items
to check if there are more than 16.

Here you have 17.

No problem, I tried to find the approreati convention.

That was a copy error on my part.  Though looking at the code
git_get_tags_list and git_get_heads_list already adds one to the limit
value, so if you pass in 17 they will return 18 items.

Sorry, I haven't noticed git_get_head_hash($project) -> $head
Sorry for the noise.

I would actually discourage this on messages that are still on
the list (i.e. not in commits).  I do [jc:] comment when I take
the proposed commit log message from the incoming e-mail
verbatim but I made modification to the patch text, because
otherwise the original submitter cannot tell from the log
message if that is meant to be identical to what was submitted.

I've only took a cursory look of the actual patch text, but what
Robert sent looked good to me.  Thanks, both.

[PATCH 1/4] gitweb: Add missing show '...' links change.

[Robert Fitzsimons]

Part of the patch for "gitweb: Show '...' links in "summary" view only
if there are more items" (313ce8cee665447e4476d7e8985b270346a8e5a1) is
missing.  Add it back in.

With all the tooing and frowing this part of the original patch got
lost.  I'm also resubmiting the original optimizations patches with a
few changes.

[PATCH 4/4] gitweb: optimize git_summary.

[Robert Fitzsimons]

We don't need to call git_get_head_hash at all just pass in "HEAD" and
use the return id field.

Refname doesn't hurt and we have it "for free" (meaning: we have to
calculate it anyway to get commiterepoch). Although we do not use it.
