调研方向

Start by reproducing tests/test_watcher.py::TestWatcher::test_watch_multiple_dirs with the reported pytest command, then read the Watcher implementation exercised by that test. Trace why a modification to the first watched directory is missed after the second directory is added; done when the targeted test passes without breaking the other watcher tests.

描述

I'm packaging your module as an rpm package so I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

  • python3 -sBm build -w --no-isolation
  • because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
  • install .whl file in </install/prefix>
  • run pytest with $PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>
  • build is performed in env which is cut off from access to the public network (pytest is executed with -m "not network")

Here is pytest output:

+ PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-livereload-2.6.3-9.fc35.x86_64/usr/lib64/python3.8/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-livereload-2.6.3-9.fc35.x86_64/usr/lib/python3.8/site-packages
+ /usr/bin/pytest -ra -m 'not network'
