The shellcheck action we uses misses some files, so they fell out of
spec for what we support. This PR first and foremost adds them to the
scanning list, and then fixes the issues found.
Fixes#7480
It transpires that detecting the directory a script was sourced from is
non-trivial across `bash`, `ksh` and `zsh`.
The previous version was a one-liner and supported `bash` and `zsh` but
not `ksh`.
It is possible to keep the one-liner and add `ksh` support, but that is
mutually-exclusive with `zsh`.
Therefore, the only way to square this circle is to add an `if` block. A
silver lining here is that although longer, the script is probably
easier to follow as there is less code-golfing going on.
## Summary
Adds a `--relocatable` CLI arg to `uv venv`. This flag does two things:
* ensures that the associated activation scripts do not rely on a
hardcoded
absolute path to the virtual environment (to the extent possible; `.csh`
and
`.nu` left as-is)
* persists a `relocatable` flag in `pyvenv.cfg`.
The flag in `pyvenv.cfg` in turn instructs the wheel `Installer` to
create script
entrypoints in a relocatable way (use `exec` trick + `dirname $0` on
POSIX;
use relative path to `python[w].exe` on Windows).
Fixes: #3863
## Test Plan
* Relocatable console scripts covered as additional scenarios in
existing test cases.
* Integration testing of boilerplate generation in `venv`.
* Manual testing of `uv venv` with and without `--relocatable`
## Summary
runpy.run_path was added in python 2.7 and 3.2 - and every python that
is not EOL supports it.
It is arguably nicer to read and the path is only given once in the
command.
At least right now, runpy - unlike exec with S102 - is not flagged by
any bandit-derived ruff check.
(I guess because it loads from a file instead of a simple string...)
Because of the import, it is also not a one-liner anymore. (But that
could be fixed with an __import__('runpy').run_path...)
## Test Plan
import runpy
runpy.run_path('/path/to/venv/bin/activate_this.py')
## Summary
Refreshes some of the activation scripts, and fixes some bugs in
`activate_this.py` that were likely the rest of some erroneous
copy-pasting.
Closes https://github.com/astral-sh/uv/issues/3346.
