sparse-revlog: implement algorithm to write sparse delta chains (
issue5480)
The classic behavior of revlog._isgooddeltainfo is to consider the span size
of the whole delta chain, and limit it to 4 * textlen.
Once sparse-revlog writing is allowed (and enforced with a requirement),
revlog._isgooddeltainfo considers the span of the largest chunk as the
distance used in the verification, instead of using the span of the whole
delta chain.
In order to compute the span of the largest chunk, we need to slice into
chunks a chain with the new revision at the top of the revlog, and take the
maximal span of these chunks. The sparse read density is a parameter to the
slicing, as it will stop when the global read density reaches this threshold.
For instance, a density of 50% means that 2 of 4 read bytes are actually used
for the reconstruction of the revision (the others are part of other chains).
This allows a new revision to be potentially stored with a diff against
another revision anywhere in the history, instead of forcing it in the last 4
* textlen. The result is a much better compression on repositories that have
many concurrent branches. Here are a comparison between using deltas from
current upstream (aggressive-merge-deltas on by default) and deltas from a
sparse-revlog
Comparison of `.hg/store/` size:

pypy (8.30% merges):

Comparison of `00manifest.d` size:

The better delta chains provide a performance boost in relevant repositories:
pypy, bundling 1000 revisions:
before: 1.670s
after: 1.149s -31%
Unbundling got a bit slower. probably because the sparse algorithm is still
pure
python.
pypy, unbundling 1000 revisions:
before: 4.062s
after: 4.507s +10%
Performance of bundle/unbundle in repository with few concurrent branches (eg:
mercurial) are unaffected.
No significant differences have been noticed then timing `hg push` and `hg
pull` locally. More state timings are being gathered.
Same as for aggressive-merge-delta, better delta comes with longer delta
chains. Longer chains have a performance impact. For example. The length of
the chain needed to get the manifest of pypy's tip moves from 82 item to 1929
items. This moves the restore time from 3.88ms to 11.3ms.
Delta chain length is an independent issue that affects repository without
this changes. It will be dealt with independently.
No significant differences have been observed on repositories where
`sparse-revlog` have not much effect (mercurial, unity, netbeans). On pypy,
small differences have been observed on some operation affected by delta chain
building and retrieval.
pypy, perfmanifest
before: 0.006162s
after: 0.017899s +190%
pypy, commit:
before: 0.382
after: 0.376 -1%
pypy, status:
before: 0.157
after: 0.168 +7%
More comprehensive and stable timing comparisons are in progress.
Set up a base, local, and remote changeset, as well as the working copy state.
Files names are of the form base_remote_local_working-copy. For example,
content1_content2_content1_content2-untracked represents a
file that was modified in the remote changeset, left untouched in the
local changeset, and then modified in the working copy to match the
remote content, then finally forgotten.

This should be the files for which the base (1st filename segment), the remote

Interestingly, one untracked file got merged and added, which corresponds to the
odd 'if force and branchmerge and different' case in manifestmerge().

Check status and file content
Some files get added (e.g. content1_content2_content1_content1-untracked)
It is not intuitive that content1_content2_content1_content4-tracked gets
merged while content1_content2_content1_content4-untracked gets overwritten.
Any *_content2_*-untracked triggers the modified/deleted prompt and then gets
overwritten.
A lot of untracked files become tracked, for example
content1_content2_content2_content2-untracked.
*_missing_missing_missing-tracked is reported as removed ('R'), which
doesn't make sense since the file did not exist in the parent, but on the
other hand, merged-in additions are reported as modifications, which is
almost as strange.
missing_missing_content3_missing-tracked becomes removed ('R'), even though
the remote side did not touch the file
