A bit of test driven dev to anticipate support of `.log.get_logger()`
usage such that it can be called from arbitrary sub-modules, themselves
embedded in arbitrary sub-pkgs, of some project; the when not provided,
the `sub_name` passed to the `Logger.getChild(<sub_name>)` will be set
as the sub-pkg path "down to" the calling module.
IOW if you call something like,
`log = tractor.log.get_logger(pkg_name='mypylib')`
from some `submod.py` in a project-dir that looks like,
mypylib/
mod.py
subpkg/
submod.py <- calling module
the `log: StackLevelAdapter` child-`Logger` instance will have a
`.name: str = 'mypylib.subpkg'`, discluding the `submod` part since this
already rendered as the `{filename}` header in `log.LOG_FORMAT`.
Previously similar behaviour would be obtained by passing
`get_logger(name=__name__)` in the calling module and so much so it
motivated me to make this the default, presuming we can introspect for
the info.
Impl deats,
- duplicated a `load_module_from_path()` from `modden` to load the
`testdir` rendered py project dir from its path.
|_should prolly factor it down to this lib anyway bc we're going to
need it for hot code reload? (well that and `watchfiles` Bp)
- in each of `mod.py` and `submod.py` render the `get_logger()` code
sin `name`, expecting the (coming shortly) implicit introspection
feat to do this.
- do `.name` and `.parent` checks against expected sub-logger values
from `StackLevelAdapter.logger.getChildren()`.
To start ensuring that when `name=__name__` is passed we try to
de-duplicate the `_root_name` and any `leaf_mod: str` since it's already
included in the headers as `{filename}`.
Deats,
- heavily document the de-duplication `str.partition()`s in
`.log.get_logger()` and provide the end fix by changing the predicate,
`if rname == 'tractor':` -> `if rname == _root_name`.
* also toss in some warnings for when we still detect duplicates.
- add todo comments around logging "filters" (vs. our "adapter").
- create the new `test_log_sys.test_root_pkg_not_duplicated()` which
runs green with the fixes from ^.
- add a ton of test-suite todos both for existing and anticipated
logging sys feats in the new mod.
