state: import the file to write state files from evolve extension The current way of writing state files is very obscure with each state file having it's own format to store state files. There is no centralized way to write state files in a good format. Moreover the current state files are not extensible, you cannot add more data to store in state files in reliable ways. To solve the problem, I wrote my own serialization and deserialization format, looked into existing formats like Protobuf, MessagePack, JSON but CBOR looks very promising and is suggested by people in the community. The current interface to store state files is to directly write data in files when things abort. Using the class imported by this commit, we can create objects which has a dict like interface and can store data on the object and store it on the file when things abort. The evolve extension is using the state file for `evolve`, `grab` commands and using it for resolution of orphaness, phase-divergence and content-divergence. The file is moved from changeset e4ac2e2c2086f977afa35e23a62f849e9305a225 of the evolve extension which is also tagged as 7.3.0. The following changes are made to the file while moving to core: * import util from current directory as this file in mercurial/ now * make cmdstate class extend object * removed mutable default value for opts in cmdstate.__init__ * some doc changes to replace out of core things with in-core ones evolve extension can be found at https://bitbucket.org/marmoute/mutable-history Differential Revision: https://phab.mercurial-scm.org/D2591

Valid URLs are of the form::
local/filesystem/path[#revision]
file://local/filesystem/path[#revision]
http://[user[:pass]@]host[:port]/[path][#revision]
https://[user[:pass]@]host[:port]/[path][#revision]
ssh://[user@]host[:port]/[path][#revision]
Paths in the local filesystem can either point to Mercurial
repositories or to bundle files (as created by :hg:`bundle` or
:hg:`incoming --bundle`). See also :hg:`help paths`.
An optional identifier after # indicates a particular branch, tag, or
changeset to use from the remote repository. See also :hg:`help
revisions`.
Some features, such as pushing to http:// and https:// URLs are only
possible if the feature is explicitly enabled on the remote Mercurial
server.
Note that the security of HTTPS URLs depends on proper configuration of
web.cacerts.
Some notes about using SSH with Mercurial:
- SSH requires an accessible shell account on the destination machine
and a copy of hg in the remote path or specified with remotecmd.
- path is relative to the remote user's home directory by default. Use
an extra slash at the start of a path to specify an absolute path::
ssh://example.com//tmp/repository
- Mercurial doesn't use its own compression via SSH; the right thing
to do is to configure it in your ~/.ssh/config, e.g.::
Host *.mylocalnetwork.example.com
Compression no
Host *
Compression yes
Alternatively specify "ssh -C" as your ssh command in your
configuration file or with the --ssh command line option.
These URLs can all be stored in your configuration file with path
aliases under the [paths] section like so::
[paths]
alias1 = URL1
alias2 = URL2
...
You can then use the alias for any command that uses a URL (for
example :hg:`pull alias1` will be treated as :hg:`pull URL1`).
Two path aliases are special because they are used as defaults when
you do not provide the URL to a command:
default:
When you create a repository with hg clone, the clone command saves
the location of the source repository as the new repository's
'default' path. This is then used when you omit path from push- and
pull-like commands (including incoming and outgoing).
default-push:
The push command will look for a path named 'default-push', and
prefer it over 'default' if both are defined.
