# The following are indirect dependencies -- dependencies of dependencies that
# we currently install via pip -- we require them here so that they will
# already be satisfied during the pip install.  (certifi is required by
# elasticsearch; bcrypt by Bcrypt-Flask; and greenlet by sqlalchemy.)  If/when
# the packages requiring these are installed via RPM, these requirements should
# no longer be necessary.

# installdir has to agree with the definition of install-dir in
# pbench-server.cfg, but we can't go out and pluck it from there,
# because we don't know where the config file is. Note that we omit
# the initial / - it is added in every use below.  IMO, that's more
# readable since it appears in the middle of the path in all cases,
# *except* in the files section (and one instance in the post
# and postun sections).

# Install python dependencies as pbench user into user's site-packages

# First, get an up-to-date pip3: the one installed through the python3 package
# is not always capable of dealing with the options that we pass it below.
# N.B. We redirect both stdout and stderr into the log here.

# The newly installed pip3 should be able to deal with the following.

# The `site` package is Python magic; it runs automatically when Python starts,
# and builds `sys.path`.
#
# For our purposes, this includes looking in the per-user site library and
# adding the site-packages paths plus adding directories captured in *.pth
# files it finds in the "user site" directory.
#
# The following line captures our install path `/${installdir}/lib` in our own
# pbench.pth file for `site` to find when the pbench user runs Python.
#
# That `pbench.pth` file needs to be in the right place, and the command
# 'python3 -m site --user-site` gives us the proper location. The `su pbench`
# ensures that this is run as "pbench" and therefore gives us the proper
# path where `pbench.pth` will be found, without making arbitrary assumptions
# about `site` package behavior.
#
# Now, when the pbench user runs Python, without any PYTHONPATH environment
# variable, the normal Python startup will include both the pbench user's
# site-library paths, and /opt/pbench-server/lib.
