mason@suse.com [Tue, 04 Apr 2006 16:47:12 -0400] rev 2079
New lazy index code for revlogs.
This tunes for large repositories. It does not read the whole
index file in one big chunk, but tries to buffer reads in more
reasonable chunks instead.
Search speeds are improved in two ways. When trying to find a
specific sha hash, it searches from the end of the file backward.
More recent entries are more likely to be relevant, especially the
tip.
Also, this can load only the mapping of nodes to revlog index number.
Loading the map uses less cpu (no struct.unpack) and much less
memory than loading both the map and the index.
This cuts down the time for hg tip on the 80,000 changeset
kernel repo from 1.8s to 3.69s. Most commands the pull a single
rev out of a big index get roughly the same benefit. Commands
that read the whole index are not slower.

Fill in the uncompressed size during revlog.addgroup
This uses code from Matt to calculate the size change that
would result from applying a delta to keep an accurate running
total of the text size during revlog.addgroup

Fix inlined revlogs to seek to eof after opening "a+"
mason@suse.com [Tue, 04 Apr 2006 16:38:44 -0400] rev 2076
Create an atomic opener that does not automatically rename on close
The revlog.checkinlinesize() uses an atomic opener to replace the
index file after converting it from inline to traditional .i and .d
files. If this operation is interrupted, the atomic file class can
overwrite a valid file with a partially written one.
This patch introduces an atomic opener that does not automatically
replace the destination file with the tempfile. This way
an interrupted checkinlinesize() call turns into a noop.

Make the appendfile class inline-data index friendly
The appendfile class needs a few changes to make it work with interleaved
index files. It needs to support the tell() method, opening in a+ mode,
and it needs to delay the checkinlinesize call until after the
append file is written.
Given that open(file, "a+") doesn't always seek to the end of the file,
this adds seek operations to appendfile that understand whence args

Fix bundle repos to use an index tuple consistent with revlogng
The bundle repo code was adding a field to the index tuple, which
confused the revlogng changes. This creates a new dict instead
to maintain the extra bundle info.

Implement data inlined with the index file
This patch allows you to optionally inline data bytes with the
revlog index file. It saves considerable space and checkout
time by reducing the number of inodes, wasted partial blocks and
system calls.
To use the inline data add this to your .hgrc
[revlog]
# inline data only works with revlogng
format=1
# inline is the only valid flag right now.
flags=inline
mason@suse.com [Tue, 04 Apr 2006 16:38:43 -0400] rev 2072
Implement revlogng.
revlogng results in smaller indexes, can address larger data files, and
supports flags and version numbers.
By default the original revlog format is used. To use the new format,
use the following .hgrc field:
[revlog]
# format choices are 0 (classic revlog format) and 1 revlogng
format=1

let run-tests run optional code coverage tests.
to enable, set env var TEST_COVERAGE to non-empty string. run-tests will
print report after running.
after coverage run, file tests/.coverage will contain coverage data. use
tests/coverage.py to get more info, like annotated source code.
