_connect_kwargs(hide_secrets = True) is used to log the connection
parameters when a connection fails, without leaking the password. The
filtered dictionary is built before the password is replaced with
'<hidden>', and the replacement is applied to the local kwargs
dictionary afterwards, after the filtered copy has already been made.
The dictionary that ends up in the log therefore still contains the
real password.
Hide the password before building the filtered dictionary.

This commit adds @override decorators to approximately 300 methods
across 76 files that inherit from base classes such as AbstractCmd,
FileContext, ExecContext, Distro, SSHClient, and others.
The decorator ensures the type checker can verify that overridden
methods have compatible signatures and prevents accidental shadowing
of inherited methods without intent.
Files modified include command classes, library modules, distro
implementations, and SSH client implementations.

The previous commits have put rules for linting and formatting via
ruff, yapf, mypy and pyright into place. They are checked with the
make check target, and this commit adds the fixes for the target to
succeed.
It does some refactoring where type checking dug up dirty bits, and
also adds lots of churn in the Python code. To a good deal, that's
owed to mere formatting changes. It would have been better to
seperate those from syntax and refactoring fixes into multiple
commits, so that the interesting changes don't drown in the
formatting nose. However, that would have been a lot of additional
work only to be thrown away by later commits, hence this commit has a
big diff in one piece. The size of the diff is regrettable but
hopefully a one-off: What it buys is automatic format checking for CI
and predictble formats for smaller diffs in the future.
Rules that "make check" enforces are, in the following order
- Syntax checkers:
- ruff check .
- mypy .
- pyright
- Format check:
- yapf --diff --recursive .
The refactoring includes:
- Turn the Result class into a more elaborate object, capable of
doing more heavy lifting around stderr and stdout decoding,
summarizing outcome, and matching error strings.
Aside from fixing broken type checks, this also removes lots of
boilerplate calling code which is currently used for handling
possible call outcome scenarios. Trying to access an inexistent,
decoded string should raise a meaningful exception by itself now,
which removes lots of code with case distinctions.
- Fix Cmd type hierarchy:
- Add the AbstractCmd class above Cmd. This is necessary because
the checker rightfully complains it can't instantiate a Cmd
instance where constructor arguments were needed. They never
were, but the type used at the instantiating code's location in
jw.pkg.App so claims.
- Lots of sub- and sub-subcommands are derived from the base
class of the invoking command. That provides some properties
shared across the ancestor hierarchy of a command, but is
semantically unsound. Fix that by introducing jw.pkg.BaseCmd
class as a place to provide basic helpers shared across all
commands used in a jw.pkg.App's context, and derive all command
classes from that afresh. The parent command is still reachable
via a common parent property.
Formatting changes are conforming to PEP-8, mostly, with minor
tweaks. All in all they include the following changes.
- Remove # -*- coding: utf-8 -*-
The line was needed by Python 2 which is not supported anylonger.
For Python 3, the default encoding is UTF-8, anyway.
- Allow to run "make py-format" without having it produce any
changes. It's basically "yapf --in-place --recursive ." with some
code style settings, see conf/topdir/pyproject.toml. The settings
may be debatable. I've had custom tweaks in place on that target,
too, but then again, IDEs would have more hassle to integrate
that.
- Introduce a 88 character line length limit
- One import per line, reshuffle them semantically, see
[tool.isort] in pyproject.toml.
- Hide imports needed for type-checking only behind
if TYPE_CHECKING
- Spaces around assignments accounts for much churn. Having having
no spaces in inline parameter list assignments and default
parameter values would arguably be more compact where it's
useful. On the other hand, I have not found a code formatter
which allows spaces around assignments in parameter lists broken
into one per line and that's often better than a wall of text.
- Add two spaces before # export, as this seems to be mandated by
PEP-8
- Use single quotes by default

Add an async open() method which should allow to do what __init__()
couldn't, because it's not async, and to match the already existing
.close(). It's called by __aenter__() __aexit__() if the FileContext

Commit a19679fec reverted the first attempt to make AsyncSSH reuse
one connection during an instance lifetime. That failed because a lot
of distribution-specific properties were filled in a new event loop
thread started by AsyncRunner, and AsyncSSH didn't like that.
The last commit provided the needed properties as members of the
Distro class. This commit is the second part of the solution: Keep
one connection around as a class member and reuse it on every _run()
invocation.

The name of the env parameter to ExecContext.run() and .sudo() is not
descriptive enough for which environment is supposed to be modified
and how, so rename and split it up as follows:
- .run(): env -> mod_env
- .sudo(): env -> mod_env_sudo and mod_env_cmd
The parameters have the following meaning:
- "mod_env*" means that the environment is modified, not replaced
- "mod_env" and "mod_env_cmd" modify the environment "cmd" runs in
- "mod_env_sudo" modifies the environment sudo runs in
Fix the fallout of the API change all over jw-pkg.

This reverts commit 04fef1e67a.
Reusing AsyncSSH's connection is fine and fast, but only if it's not
combined with the AsyncRunner. See commit 67e51cf0 why it was
introduced in the first place, along with a reasoning why it may be a
bad idea. Looks like we're now reaping what we sowed.
The current plan to get this to fly is to sprinkle async / await all
over the code paths to App.os_release(). That is a lot of churn, so
postpone and revert for now to keep CI working.

The Input instance passed as cmd_input to ExecContext.run() and
.sudo() currently may be of type str. Allow to pass bytes, too.
At the same time, disallow None to be passed as cmd_input. Force the
caller to be more explicit how it wants input to be handled, notably
with respect to interactivity.
Along the way fix a bug: Content in cmd_input should result in
CallContext.interactive == False but doesn't. Fix that.

Request a remote PTY from AsyncSSH, and wire the local terminal's

Add a SSHClient implementation using AsyncSSH. This is the first and
currently only class derived from SSHClient which implements
SSHClient.Cap.LogOutput, designed to consume and log command output
as it streams in. It felt like the lower hanging fruit not to do that
with Paramiko: Paramiko doesn't provide a native async API, so it
would need to spawn additional worker threads. I think.
