Merge 3.24 branch

Added tag 3.24.1, debian/3.24.1-1, centos/3.24.1-1 for changeset da52fda6f15b

[debian] update changelog's time tag

[pyramid] Drop reference to pyramid_cubicweb in ctl command docstring [ci skip]

[debian] Rework split of cubicweb-ctl package It does not appear simple to have the .install files work. So just copy cubicweb-ctl script in DESDIR of cubicweb-ctl binary package and remove .install files. Related to #16133259.

[skeleton] Rephrase long description of Debian package into something meaningful [ci skip]

[skeleton] Depends on python-cubicweb in debian packaging [ci skip]

[debian] Have a single python-cubicweb binary for the library But keep distinct meta-packages for dependencies of the HTTP server (Twisted/Pyramid) and database backend. Related to #16133259.

[debian] Update debian packaging (closes #16133259) - use dh_python, pybuild and debhelper>=9, - refactor and simplify the debian/rules, - rename binary packages (but cubicweb-ctl) to python-xxx - remove daemon handling stuff (initscripts...) from cubicweb-ctl (one should now use a standard WSGI delivery method),

[pkg] Version 3.24.1

[tox] Use `python -m check_manifest` instead of check-manifest program To make sure we use Python from tox's virtualenv.

add debian buildpackage-generated files to hgignore

[test] Fix language negotiation test At least when executed alone (there seems to be a test isolation problem which I could not figure out).

[pyramid] No more need for an internal connection when user is cached

[web] req.lang should be None or a non-empty string

[web] Simplify a bit language handling Drop `set_default_language` and `set_user_language` by considering that: * before being bound to the user, request will have the site's default language * cnx has the user's preferred language, hence get it back to the request when it's bound to a connection The first point requires some change to cubicweb's vreg faking so it doesn't break. That should be enough.

Fix AttributeError for "lang" on repo/client connections This is a regression introduced by b48020a80dc3, which removed call to set_language from the `req._set_user` method. This is fine, but we still want a language on connections, so we've to handle it if necesary in Connection.__enter__ (i.e. once connection is properly open). When using pyramid front-end, which has a users cache, we've to cache its language as well because we must not access its preferred_language method since it's not bound to a proper connection.

Alias ugettext to gettext method of cwGNUTranslations in Python 3 The former does not exist in Python 3, but we rely on it. This fixes test_login_bad_password in cubicweb/pyramid/test/test_login.py which has never passed since being introduced in 6392f34fcdad.

[devctl] make i18n custom message extractors work with legacy layouts distname needs to be "cubicweb_<cubename>", even with legacy layouts for pkg.load_entry_point() to work closes #16272177

Fix (new) flake8 errors They showed up on upgrade of flake8/pep8.

[pyramid] Try "eid" first when retrieving a subresource of ETypeResource So that Pyramid traversal works as existing CubicWeb URL publishing.

Fix AttributeError on postcommit when db-create adds non-system CWSource entities In this case, `Repository.add_source` is called from an operation, not from `Repository.init_sources_from_database`, thus the attribute `sources_by_eid` does not exist. Closes #16251078.

[devctl] Optimize cleanup_sys_modules a bit by moving out of a loop a costly computation that is constant. This at least benefits the `i18ncube` command. Related to #15789486.

[pyramid] Install file listing monitored files in application home Instead of using a temporary file, that never gets deleted. Closes #16159807.

[pyramid] Fix login error message language Use http negotiation unless language is explicitly set for the site. Closes #16236485.

i18n update Pyramid-related messages were not translated. Closes #16236243.

[pyramid] Add action verb used in some messages displayed by the command For instance we'll see 'instance started' instead of 'instance None', which is nicer.

[pyramid] No more need to check CW version since it's now shipped with it

[pyramid] Fix 404 handling Avoid seeing a traceback in the UI by catching it before it reaches pyramid and restore usage of the '404' view. Closes #16159863

Fix broken flake8 configuration and flake8 errors which were hidden by this breakage. flake8 --filename options doesn't work as expected: * it's expected to be a shell pattern, using stdlib's fnmatch.fnmatch function internally. This funciton thinks that 'cubicweb/x.py' doesn't match 'cubicweb/x.py' (there must be a reason but that's not the point), hence no file was actually checked ; * as this is a list of pattern, each encountered file is checked against each pattern, leading to run time explosion. So maintain list of files to check in a separated file and give this list to flake8 using unix's xarg command.

[entities] Fix typo in wfobjs debug message
