jw.pkg: Fix "make check" static code check fallout
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 Signed-off-by: Jan Lindemann <jan@janware.com> |

App.distro_xxx: Move properties to Distro.xxx
Commit This commit is the first part of the solution: Move those properties from the App class to the Distro class, and load the Distro class in an async loader. As soon as it's instantiated, it can provide all its properties without cluttering the code with async keywords. Signed-off-by: Jan Lindemann <jan@janware.com> |

lib.FileContext.put(): Change param mode type str -> int
Don't pass mode as a string to put(). Given the multitunde of possible string representations for numbers, some understood by int(string, 0) and some not, there's too much room for passing strings which are unparseable, or worse, prone to be parsed wrongly. However, pass mode down to _put() as a string for convenience, because that's what most _put() implementations will need to use. If they don't, converting to int is easy from the one defined string format. Signed-off-by: Jan Lindemann <jan@janware.com> |

cmds.posix.CmdCopy: Support platform macros
Expand platform macros (as in %{codename}) in the src and dst command arguments. Expansion can be turned off by -F --fixed-strings. Signed-off-by: Jan Lindemann <jan@janware.com> |

cmds.posix.CmdCopy: Add module
Add CmdCopy, designed to copy data from the filesystem to another location in the filesystem. Not necessarily local file systems, the URLs can be all URLs supported by ExecContext.run(). Signed-off-by: Jan Lindemann <jan@janware.com> |
