Before this patch, zip archives created by "hg archive" are extracted
with unexpected timestamp, if TZ is not configured as GMT.
This patch adds "extended-timestamp" extra block to zip archives, and
unzip will extract such archives with timestamp specified in added
extra block, even though TZ is not configured as GMT.
Please see documents below for detail about specification of zip file
format and "extended-timestamp" extra block:

I don't think we will ever have anything in the store that resides inside a
directory that ends in .i or .d under store/ that we wouldn't want to have
direncoded. The files not under data/ surely don't need direncoding, but it
doesn't harm to let these few run through it. It hurts more to check whether the
thousands of other files start with 'data/'. They do anyway.
See also 67e6074ba430 (fixed with 0c522fe42894), which moved the direncoding
from filelog into store
by refactoring
for i, n in enumerate(res):
if n:
<main code block>
to
for i, n in enumerate(res):
if not n:
continue
<main code block>
(no functional change)
46cdcb89086f fixed display of non-ASCII names in file-selecting prompt, but
display in chunk selection remained broken. The reason is that using '%r' in
string formatting results in calling `repr` on file names, thus mangling
non-ASCII ones.
Merely creating and using a generator has a measurable impact,
particularly since the common case for stream_out is generators that
yield just once. Avoiding generators improves stream_out performance
by about 7%.
Auditing at this stage is both pointless (paths are already trusted by
the local repo) and expensive. Skipping the audits improves stream_out
performance by about 15%.
Examples (all done with somewhat dated clones I found on my disk):
Netbeans (~120k entries in fncache):
$ hg perffncacheencode
! wall 4.338000 comb 4.336828 user 4.336828 sys 0.000000 (best of 3)
Openoffice (~77k entries in fncache)):
$ hg perffncacheencode
! wall 1.533000 comb 1.528810 user 1.528810 sys 0.000000 (best of 7)
Xen (~10k entries in fncache):
$ hg perffncacheencode
! wall 0.198000 comb 0.187201 user 0.187201 sys 0.000000 (best of 51)
Done on Windows 7 x64.
When we rewrite a bookmarked changeset, we want to update the
bookmark on its successors. But the successors are not descendants
of its precursor (by definition). This changeset alters the bookmarks
logic to update bookmark location if the newer location is a successor
of the old one[1].
note: valid destinations are in fact any kind of successors of any kind
of descendants (recursively.)
This changeset requires the enabling of the obsolete feature in
some bookmark tests.
We usually update bookmarks only if the new location is descendant of the old
bookmarks location. We extract this logic into a function. This is the first
step to allow more complex logic using obsolescence in this validation of the
bookmark movement.
