rHG0e03e6a44dee: wireprotov2: define and implement "filedata" command
Summary

Continuing our trend of implementing *data commands for retrieving
information about specific repository data primitives, this commit
implements a command for retrieving data about an individual tracked
file.

The command is very similar to "manifestdata." The only significant
difference is that we have a standalone function for obtaining
storage for a tracked file. This is to provide a monkeypatch point
for extensions to implement path-based access control.

With this API available, wire protocol version 2 now exposes all
data primitives necessary to implement a full clone. Of course,
since "filedata" can only resolve data for a single path at a time,
clients would need to issue N commands to perform a full clone. On
the Firefox repository, this would be ~461k commands. We'll likely
need to implement a file data retrieval command that supports
multiple paths. But that can be implemented later.

In general I'm happy with where this is going, but I'm extremely uncomfortable with the manifest and filelog commands requiring so much client-server transfer to get everything, especially the rpc-per-file nature of this. It's elegant in terms of how easy it'll make remotefilelog et al, but it makes me worried about performance in the small-repo case where today we can just issue one big hoss RPC for everything and we get it all in one go.

This revision is now accepted and ready to land.Sep 12 2018, 11:11 AM

Oh, one more thing: I think this, as-stated, will make it at best challenging to have ACLed branches: we'd have to, on the server, walk the linknodes and see if the client was authorized to see any branch(es) that contain the node.

That's probably okayer for us than it was for git (since we have linkrevs at least), but it's still worth considering.

First, totally agree with you about wire protocol / command overhead. I plan to add bulk querying APIs later.

Also, I wasn't aware of the ACL'd branches requirement. I'll have to think of ways to handle that. It may involve the server advertising the available mechanisms for requesting file data (e.g. "request by file node" and "request by changeset node") and the server not allowing certain modes. But that example would undercut raw data access. So maybe it gets advertised as a server preference. Or maybe we end up not doing the "request by file node" path in the common case and the server overhead isn't a problem in practice.

I'll keep this use case in mind when writing future commits.

filedata
--------
Obtain various data related to an individual tracked file.
The command accepts the following arguments:
fields
(set of bytestring) Which data associated with a file to fetch.
The following values are recognized:
parents
Parent nodes for the revision.
revision
The raw revision data for a file.
nodes
(array of bytestrings) File nodes whose data to retrieve.
path
(bytestring) Path of the tracked file whose data to retrieve.
TODO allow specifying revisions via alternate means (such as from
changeset revisions or ranges)
The response bytestream starts with a CBOR map describing the data that
follows. It has the following bytestream keys:
totalitems
(unsigned integer) Total number of file revisions whose data is
being returned.
Following the header map is a series of 0 or more CBOR values. The first
value is always a map describing a file revision. If this map has the
``deltasize`` or ``revisionsize`` keys, a bytestring containing the delta
or revision, respectively, will immediately follow the map. Otherwise
the next value will be a map describing the next file revision.
Each map has the following bytestring keys:
node
(bytestring) The node of the file revision whose data is represented.
deltabasenode
(bytestring) Node of the file revision the following delta is against.
Only present if the ``revision`` field is requested and delta data
follows this map.
deltasize
(unsigned integer) The size of the delta data that follows this map.
Only present if the ``revision`` field is requested and delta data
follows this map.
parents
(array of bytestring) The nodes of the parents of this file revision.
Only present if the ``parents`` field is requested.
revisionsize
(unsigned integer) The size of the fulltext revision data that follows
this map.
Only present if the ``revision`` field is requested and fulltext revision
data follows this map.
When ``revision`` data is requested, the server chooses to emit either fulltext
revision data or a delta. What the server decides can be inferred by looking
for the presence of the ``deltasize`` or ``revisionsize`` keys in the map.
Servers MUST NOT define both keys.

----- -----
Obtain DAG heads in the repository. Obtain DAG heads in the repository.
