"jw-pkg secrets install" copies secret material from a GPG-encrypted tar
archive to dotenv .jw-secret files on a target host. This commit refactors
the underlying code and adds hooks for the inverse copy direction, and for
more secret sources and targets.
The peers between which secrets are copied are represented by the new
abstract secret_store.Base class, and the existing tar blob and host
storages, inheriting from that class, are TarGpg and KvFile. Moreover,
secret_store.Base is inheriting from FileContext, so all of jw-pkg's
file-like operations are available as hooks.
Secrets inside instances of two file contexts are addressable as
(targpg|kvfile)://target.host.com/path/to/file.conf.jw-secret. The on-host
KvFile will look either locally or via SSH for that file, and TarGpg will
look inside a tar archive specified in the JW_SECRETS_TARGPG_TAR
environment variable.
Uris with these schemas can be passed to FileContext.create(), which will
return a chrooted file context of the correct type.
KvFile.stat("/path/to/file.conf.jw-secret").ftype is FT_SECRET which
inherits from FT_COMPOUND - which means that readdir() works on such
animals. Not entirely sure if that's a good idea, but it feels pretty
generic. Let's see where that takes us.
DistroContext.install() after this refactor reads its source through the
store interface and writes the landing through the KvFile store.
Both secret stores are exercised through the existing unit test of jw-pkg
secrets install, and unit tests for both stores are also added by this
commit.

File attributes of the compiled output of "jw-pkg secrets
compile-templates" can be specified via the # conf line atop a .jw-tmpl
file, the parsing of that line is buggy, however.
Its mode is parsed as a decimal number unless it carries a leading zero, so
"mode=640" yields 640 decimal, 1200 octal, and the output file ends up
without usable permissions. The same decimal parse applies to a conf line atop
the .jw-secret of a target, whose attributes are honored the same way, and
the --mode option of compile-templates passes its string value through to
Attrs, whose mode is typed int, so a target without a conf line of its own
crashes in _format_metadata().
Other than that, the # conf line itself should be removed from the compiled
output, but isn't.
This commit makes the conf line handling correct:
- _parse_attributes() parses the mode as octal, with or without a leading
zero
- _compile_one_template_file() drops the conf line from the compiled
content
- the --mode option is converted to an octal int by octal_mode() at the
argument boundary
The integration test writes its conf line modes without leading zeros,
expects the conf line gone from the compiled output, takes one target's
mode from a conf line atop its .jw-secret, and passes a --mode that the
conf lines override.

rewrite() renames the members of a tar blob, but the TarInfo objects
carried over from the input still hold the pax "path" supplement that was
recorded for the original name. Re-serialization (tf_out.addfile()) uses
the pax supplement with higher precedence than what's in the base header's
name filed, so for member names exceeding the 100 character ustar limit the
rewrite silently has no effect and the original name is written back.
Drop the stale "path" supplement after renaming a member. tf_out.addfile()
then builds a rewritten, up-to-date supplement from the name field if it
needs one.

Add new ruff rules and fix their fallout:
future-annotations = true
select = [
"TC", # type-checking import placement rules
"FA", # future annotations rules

This comprises:
- Streamline imports and exports in cmds.xxx.Cmd
- Import base class as "Base"
- Export types Cmd and Parent via __all__
- Move all types imported only for annotation below TYPE_CHECKING
- Use "from __future__ import annotations" all over the place

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
