wireprotov2peer: stream decoded responses...
wireprotov2peer: stream decoded responses Previously, wire protocol version 2 would buffer all response data. Only once all data was received did we CBOR decode it and resolve the future associated with the command. This was obviously not desirable. In future commits that introduce large response payloads, this caused significant memory bloat and slowed down client operations due to waiting on the server. This commit refactors the response handling code so that response data can be streamed. Command response objects now contain a buffered CBOR decoder. As new data arrives, it is fed into the decoder. Decoded objects are made available to the generator as they are decoded. Because there is a separate thread processing incoming frames and feeding data into the response object, there is the potential for race conditions when mutating response objects. So a lock has been added to guard access to critical state variables. Because the generator emitting decoded objects needs to wait on those objects to become available, we've added an Event for the generator to wait on so it doesn't busy loop. This does mean there is the potential for deadlocks. And I'm pretty sure they can occur in some scenarios. We already have a handful of TODOs around this. But I've added some more. Fixing this will likely require moving the background thread receiving frames into clienthandler. We likely would have done this anyway when implementing the client bits for the SSH transport. Test output changes because the initial CBOR map holding the overall response state is now always handled internally by the response object.

PatchReview Introduction *patchreview-intro*
The Patch Review plugin allows easy single or multipatch code or diff reviews.
It opens each affected file in the patch or in a workspace diff in a diff view
in a separate tab.
VIM provides the |:diffpatch| and related commands to do single file reviews
but can not handle patch files containing multiple patches as is common with
software development projects. This plugin provides that missing
functionality.
It also improves on |:diffpatch|'s behavior of creating the patched files in
the same directory as original file which can lead to project workspace
pollution.
It does automatic diff generation for various version control systems by
running their diff command.
=============================================================================
PatchReview Options *patchreview-options*
g:patchreview_patch = {string}
Optional path to patch binary. PatchReview tries to locate patch on
system path automatically. If the binary is not on system path, this
option tell PatchReview the full path to the binary. This option, if
specified, overrides the default patch binary on the path.
examples:
(On Windows with Cygwin) >
let g:patchreview_patch = 'c:\\cygwin\\bin\\patch.exe'
<
(On *nix systems) >
let g:patchreview_patch = '/usr/bin/gpatch'
<
g:patchreview_filterdiff = {string}
Optional path to filterdiff binary. PatchReview tries to locate
filterdiff on system path automatically. If the binary is not on system
path, this option tell PatchReview the full path to the binary. This
option, if specified, overrides the default filterdiff binary on the
path.
examples:
(On Windows with Cygwin)
>
let g:patchreview_filterdiff = 'c:\\cygwin\\bin\\filterdiff.exe'
<
(On *nix systems)
>
let g:patchreview_filterdiff = '/usr/bin/filterdiff'

=============================================================================
PatchReview Usage *patchreview-usage*
*:DiffReview*
:DiffReview
Perform a diff review in the current directory under version control.
Currently supports Mercurial (hg), Subversion (svn), CVS, Bazaar (bzr) and
Monotone.
*:PatchReview*
:PatchReview patchfile_path [optional_source_directory]
Perform a patch review in the current directory based on the supplied
patchfile_path. If optional_source_directory is specified, patchreview is
done on that directory. Otherwise, the current directory is assumed to be
the source directory.
Only supports context or unified format patches.
