support for multiple snapshot formats changed the format of

gitweb.snapshot configuration variable (repository configuration).
It supported old gitweb.snapshot values of 'gzip', 'bzip2' and 'zip'

$feature{'snapshot'}{'default'}; at least those corresponding to

  ['x-gzip', 'gz', 'gzip']
  ['x-bzip2', 'bz2', 'bzip2']
  ['x-zip', 'zip', '']

This commit moves legacy configuration support out of feature_snapshot
subroutine to separate filter_snapshot_fmts subroutine. The
filter_snapshot_fmts is used on result on result of
gitweb_check_feature('snapshot').  This way feature_snapshot deals
_only_ with repository config.

As a byproduct you can now use 'gzip' and 'bzip2' as aliases to 'tgz'
and 'tbz2' also in $feature{'snapshot'}{'default'}, not only in
gitweb.snapshot.

  information is specified.  In particular, zip files are no longer a

- Add support for offering multiple snapshot formats to the user so

  The site-wide or project configuration now gives a list of formats

  link becomes something like "snapshot (_tar.bz2_ _zip_)".

  tells the user what it is.

three pieces of information about a single format to a list of one or
more formats you wish to offer from the set ('tgz', 'tbz2', 'zip').
Update your gitweb_config.perl appropriately.  There was taken care
for old-style gitweb configuration to work as it used to, but this
backward compatibility works only for the values which correspond to
gitweb.snapshot values of 'gzip', 'bzip2' and 'zip', i.e.

  ['x-bzip2', 'bz2', 'bzip2']

Rename read_pipe() with read_fd() and make its buffer nul-terminated.

The new name is closer to the purpose of the function.

A NUL-terminated buffer makes things easier when callers need that.
Since the function returns only the memory written with data,
almost always allocating more space than needed because final
size is unknown, an extra NUL terminating the buffer is harmless.
It is not included in the returned size, so the function
remains working as before.

Also, now the function allows the buffer passed to be NULL at first,
and alloc_nr is now used for growing the buffer, instead size=*2.

Do a better job at guessing unknown character sets

At least in the kernel development community, we're generally slowly
converting to UTF-8 everywhere, and the old default of Latin1 in emails is
being supplanted by UTF-8, and it doesn't necessarily show up as such in
the mail headers (because, quite frankly, when people send patches
around, they want the email client to do as little as humanly possible
about the patch)

Despite that, it's often the case that email addresses etc still have
Latin1, so I've seen emails where this is a mixed bag, with Signed-off
parts being copied from email (and containing Latin1 characters), and the
rest of the email being a patch in UTF-8.

So this suggests a very natural change: if the target character set is
utf-8 (the default), and if the source already looks like utf-8, just
assume that it doesn't need any conversion at all.

Only assume that it needs conversion if it isn't already valid utf-8, in
which case we (for historical reasons) will assume it's Latin1.

Basically no really _valid_ latin1 will ever look like utf-8, so while
this changes our historical behaviour, it doesn't do so in practice, and
makes the default behaviour saner for the case where the input was already
in proper format.

We could do a more fancy guess, of course, but this correctly handled a
series of patches I just got from Andrew that had a mixture of Latin1 and
UTF-8 (in different emails, but without any character set indication).

"unlink()" on a directory (race conditions etc), but that's
fundamentally true (there is no "funlink()" like there is

gitk: Fix bug introduced by previous commit

When I added the "--" case to the code scanning the arguments, I missed
the fact that since the switch statement uses -regexp, the "--" case
will match any argument containing "--", e.g. "--all".  This fixes it
by taking out the -regexp (since we don't actually need regular
expression matching) and adjusting the match strings.

A side effect of this is that previously any argument starting with
"-d" would be taken to indicate date mode; now the argument has to be
exactly "-d" if you want date mode.

Nicolas Pitre [Thu, 12 Jul 2007 18:33:21 +0000 (14:33 -0400)]
apply delta depth bias to already deltified objects

We already apply a bias on the initial delta attempt with max_size being
a function of the base object depth.  This has the effect of favoring
shallower deltas even if deeper deltas could be smaller, and therefore
creating a wider delta tree (see commits 4e8da195 and c3b06a69).

This principle should also be applied to all delta attempts for the same
object and not only the first attempt.  With this the criteria for the
best delta is not only its size but also its depth, so that a shallower
delta might be selected even if it is larger than a deeper one.  Even if
some deltas get larger, they allow for wider delta trees making the
depth limit less quickly reached and therefore better deltas can be
subsequently found, keeping the resulting pack size even smaller.
Runtime access to the pack should also benefit from shallower deltas.

Testing on different repositories showed slighter faster repacks,
smaller resulting packs, and a much nicer curve for delta depth
distribution with no more peak at the maximum depth level.
Improvements are even more significant with smaller depth limits.
