wireprotov2peer: wait for initial object before resolving future
As part of rolling out wireprotov2 with redirect support, I
encountered an edge case with regards to future resolution.
Essentially, the initial response frame from the server did not
fully decode the initial CBOR object. The frame wasn't marked as
EOS. In the previous code, we resolved the future for the request
to response.objects(), which mapped to the commandresponse instance
which would eventually produce a redirect. Upon receiving
subsequent data, the initial CBOR object containing the redirect
would be decoded and we'd process the redirect. However, the
future would already have been resolved with the initial
commandresponse.objects() and the client iterating over the
objects wouldn't receive any objects from the redirect because
the redirect was populating a different commandresponse instance!
This commit changes the logic so we don't resolve futures until
the initial CBOR response object is fully decoded or until EOS
occurs. In cases where there is an empty or partial frame
associated with a redirect, the future will now resolve with the
commandresponse containing the proper series of decoded objects.

wireprotov2peer: always return a bool from _processredirect()
Without this, we may stop servicing the redirect response if the
future has already been resolved. And the future will often be
resolved very early, since many consumers iterate the decoded
CBOR object stream and expect data to lazily arrive.

checkexec: create destination directory if necessary
Since 460733327640, a "share" use the cache of the source repository. A side
effect is that no `.hg/cache` directory exists in the "share" anymore. As a
result, the checkexec logic can't use it to create its temporary file and have
to use the working copy for that.
This is suboptimal, it pollutes the working copy and prevents them to keep the
file around in cache. We do not want to use the cache directory for the share
target, it might be on a different file system.
So instead, we (try to) create the directory if it is missing. This is a
simple change that fixes the current behavior regression on stable.
On default, we should probably ensure the proper directories are created when
initializing the repository. We should also introduce a 'wcache' directory to
hold cache file related to the working copy. This would clarify the cache
situation regarding shares.
The tests catch a couple of other affected cases.

subrepo: print the status line before creating the peer for better diagnostics
I ran into a problem where I tried updating to a different branch, and the
process appeared to hang. It turned out that the subrepo revision wasn't
available locally, and I must have originally cloned it from an `hg serve -S` on
a machine that currently wasn't serving anything. It took 2+ minutes to
timeout, and didn't mention what it was connecting to even then.
There are a couple of other issues in this scenario too.
- The repo is dirty after the failed checkout because the top level repo is
updated first. We should probably make 2 passes- top down to pull
everything needed, and then do an update once everything is in place.
- Something must be reading .hgsubstate from wdir because if the same merge
command is run after the timeout, a prompt is issued that the local and
remote subrepo diverged, instead of hanging. But it lists the local version
and remote version as having the same hash.

hgweb: cast bytearray to bytes
PEP-3333 seems to indicate that bytes is the only allowed type that can
be used to express the output of a WSGI application. And some WSGI
environments seem to enforce this (mod_wsgi does).
This commit universally casts bytearray instances to bytes to appease
the WSGI specification.
I found this because wireprotov2 is emitting bytearray instances. I'd
like to keep things that way because the way it builds a data
structure, bytearray is more efficient. I'd rather keep the low-level
code efficient (and using bytearray) and cast at the edges than impose
a performance penalty on code that may run outside WSGI contexts.

resolve: when resolve.mark-check=abort, downgrade to warning if pats specified
Previously, with --config resolve.mark-check=abort, running `hg resolve -m foo`
would abort and emit a message saying to use --all. This command does not work,
though: `hg resolve -m foo --all`, and it's really weird for --all to be the
"--force" flag.
My original goal with the option was to make it so that `hg resolve -m` (no
filename arguments) was safer, which is why --all is used; in my mind, `hg
resolve -m foo` should always mark it as resolved, and `--all` is how you
specify "all the files", so that's why I chose `hg resolve -m --all` as the way
out of `hg resolve -m` aborting. This commit makes all of this work the way it
was meant to in my head :)

changegroup: restore default node ordering (issue6001)
Changeset db5501d9 changed the default node ordering from "storage" to
"linearize".
While the new API is more explicit and cleaner, the "linearize" order is
problematic on certain repositories like netbeans where it makes bundling
slower the more nodes we bundle.
Pushing and pulling 100 changesets was ~20% slower and pushing and pulling
1000 changesets was ~600% slower.
A very quick analysis of profile traces showed that the pull operation was
taking more time creating the delta.
Putting back the old default order seems to be the safe option. With more time
during the next cycle, we can understand better the impact of sorting with the
DAG order by default, the source of the regression and how to mitigate it.
/!\ We are still waiting for the full performance impact but with this patch,
bundling and pulling locally (not on the performance workstation) 1000
changesets on the netbeans repository is as fast as before the regression.

sparse-revlog: only refine delta candidates in the sparse case (issue6006)
Starting with 5aef5afa8654, a valid delta parent might be "refined". This
allows repository using sparse-revlog to produce better delta chain by using
better intermediate snapshot base.
However, this refining step was performed in all cases, including for
repository not using sparse-revlog. This could produce a strange chain in the
general delta case and corrupted repository in the non-general delta case.
We now skip this step unless sparse-revlog is in use.
In issue 6006, Yuya Nishihara provided a test case using an external
repository, so we did not include it. Finding "laboratory" condition to
reproduce this case and implementing an efficient test reproducing it is a bit

phase: add an archived phase
This phase allows for hidden changesets in the "user space". It differs from
the "internal" phase which is intended for internal by-product only. There
have been discussions at the 4.8 sprint to use such phase to speedup cleanup
after history rewriting operation.
Shipping it in the same release as the 'internal-phase' groups the associated
`requires` entry. The important bit is to have support for this phase in the
earliest version of mercurial possible. Adding the UI to manipulate this new
phase later seems fine.
The current plan for archived usage and user interface are as follow. On a
repository with internal-phase on and evolution off:
* history rewriting command set rewritten changeset in the archived phase.
(This mean updating the cleanupnodes method).
* keep `hg unbundle .hg/strip-backup/X.hg` as a way to restore changeset for
now
(backup bundle need to contains phase data)
* [maybe] add a `hg strip --soft` advance flag
(a light way to expose the feature without getting in the way of a better
UI)
Mercurial 4.8 freeze is too close to get the above in by then.
We don't introduce a new repository `requirement` as we reuse the one
introduced with the 'archived' phase during the 4.8 cycle.

Only shallow fetching of files data is supported: shallow fetching of

Previously, we would fetch file revisions for changesets that were received

"relevant" changesets given the pull depth and only fetch files data for
those changesets.
We also teach the "filesdata" command invocation to vary parameters as needed.
The implementation here is far from complete or optimal. Subsequent pulls will
end up re-fetching a lot of files data. But the application of this data should
mostly be a no-op on the client, so it isn't a big deal.
Depending on the order file revisions are fetched in, revisions could get
inserted with the wrong revision number relationships. I think the best way
to deal with this is to remove revision numbers from storage and to either
dynamically derive them (by reconstructing a DAG from nodes/parents) or remove
revision numbers from the file storage interface completely.
A missing API that we'll likely want to write pretty soon is "ensure files
for revision(s) are present." We can kind of cajole exchangev2.pull() to do
this. But it isn't very efficient. For example, in simple cases like
widening the store to obtain data for a single revision, it is probably
more efficient to walk the manifest and find exactly which file revisions
are missing and to make explicit requests for just their data. In more
advanced cases, asking the server for all files data may be more efficient,
even though it requires sending data the client already has. There is tons
of room for future experimentation here. And TBH I'm not sure what the
final state will be.
Anyway, this commit gets us pretty close to being able to have shallow
and narrow checkouts with exchangev2/sqlite storage. Close enough that a
minimal extension should be able to provide fill in the gaps until the code
in core stabilizes and there is a user-facing way to trigger the
narrow/shallow bits from `hg clone` without also implying using of the
narrow extension...

sqlitestore: support for storing revisions without their parents
This commit kinda/sorta implements the equivalent of ellipsis nodes for
the SQLite storage backend.
Without implementing full blown ellipsis nodes (and the necessary support for
them in the wire protocol), we instead teach the store to rewrite the p1 and
p2 nodes to nullid when the incoming parent isn't in the local store. This allows
servers to remain dumb and send the real parent and have the clients deal
with the missing parent problem.
This obviously isn't ideal because a benefit of ellipsis nodes is we can
insert a fake parent to ellide missing changesets. But neither solution is
ideal because it drops the original parent from storage. We could probably
teach the SQLite store to retain the original parent and handle missing
parents at read time. However, parent revisions are stored as integers and
it isn't trivial to store an "empty" revision in the store yet, which would
be necessary to represent the "missing" parent.
The store is somewhat intelligent in trying to remove the missing parents
metadata when the revision is re-added. But, revision numbers will be all
messed up in that case, so I'm not sure it is worth it. At some point we'll
likely want to remove the concept of revision numbers from the database and
have the store invent them at index generation time. Or even better, we can
do away with revision numbers from the file storage interface completely.
We'll get there eventually...

wireprotov2: support exposing linknode of file revisions
When supporting shallow file storage, clients may fetch file revisions
by changeset. But they may not readily know which changeset introduced a
specific file revision. The "linknode" is used to record which changeset
introduces which file revision.
This commit teaches the "filedata" and "filesdata" wire protocol commands
to expose the linknode for file revisions. The implementation is likely
wrong when hidden changesets are in play, since the linknode may refer to
a hidden changeset. We can deal with this problem later.

localrepo: support marking repos as having shallow file storage
Various operations against repositories need to know if repository
storage is full or partial. For example, a checkout (including possibly
a widening of a sparse checkout), needs to know if it can assume all file
revisions are available or whether to look for missing revisions first.
This commit lays the plumbing for doing that.
We define a repo creation option that indicates that shallow file storage
is desired.
The SQLite store uses this creation option to add an extra repo requirement
indicating file storage is shallow.
A new repository feature has been added to indicate that file storage is
shallow. The SQLite store adds this feature when the shallow file store
requirement is present.
Code can now look at repo.features to determine if repo file storage may
be shallow and take additional actions if so.
While we're here, we also teach the SQLite store to handle the narrow repo
requirement, which gets added when making narrow clones.

repository: teach addgroup() to receive data with missing parents
The way the narrow extension works today, the server rewrites
outgoing changegroup data to lie about parents when the parents
data is missing. It adds the ellipsis flag to the revision so
it can be recorded as such in the revlog.
In the new wire protocol, such rewriting does not occur on
the server (at least not yet anyway). Instead, it is up to the
client to recognize when it has received a revision without its
parents. This means rewriting will be performed on the client.
Furthermore, the mechanism for storing a shallow revision may
differ from store to store. For example, the revlog store uses
the ellipsis flag to denote a revision's parents have been
rewritten. But a non-revlog store may wish to store things
differently. And, some stores may not even support receiving
shallow revision data!
Therefore, it makes sense for the store itself to be making
decisions about what to do when they receive revision data
without their parents.
This commit teaches the addgroup() bulk insert method to accept
a boolean argument that indicates whether the incoming data may
lack parent revisions. This flag can be set when receiving
"shallow" data from a remote.
The revlog implementation of this method has been taught to rewrite
the missing parent(s) to nullid and to add the ellipsis flag to
the revision when a missing parent is encountered. But it only
does this if ellipsis flags are enabled on the repo and the
incoming data is marked as possibly shallow. An error occurs
otherwise.

filelog: add a hasnode() method (API)
Missing in the file storage interface is the ability to query whether
a specified value is a known node.
This commit defines that interface member and implements it on the
revlog and sqlite file stores.
Storage unit tests have been added.
The revlog implementation is a bit more complicated because index lookups
don't consistently raise the same exception. For SQLite, we can simply look
for a key in a dict.

lfs: consult the narrow matcher when extracting pointers from ctx (issue5794)
I added a testcase for lfs to all narrow tests, and the following failed:
test-narrow-acl.t
test-narrow-exchange.t
test-narrow-patterns.t
test-narrow-strip.t
test-narrow-trackedcmd.t
test-narrow-widen.t
test-narrow.t
The first two still have errors in the pretxnchangegroup on clone and (receiving
a) push, which I'm still looking into (4d63f3bc1e1a fixed something in this area
already). These two modified tests seem to cover the things that failed in the
remaining narrow tests, i.e. `hg tracked` and `hg strip`, so I didn't bother
enabling the testcases elsewhere. Maybe we should, but it's 68 tests total.
