+# This script installs xmlsec dependencies and should be run as root
+
+# The following explanation is for why we need to install pkg-config and other system
+# packages.
+#
+# TL;DR: In the Airflow update from 2.9 to 2.10, xmlsec was added as a dependency.
+# xmlsec is a Python package that requires the xmlsec C library installed. This script
+# installs the C library.
+#
+# In the Jenkins container the `install-deps` target in the Makefile is called. The
+# Makefile `install-deps` target is installing dependencies from the MWAA requirements
+# file: docker/config/mwaa-base-providers-requirements.txt. In that file, it lists
+# apache-airflow-providers-amazon[aiobotocore]==x.x.x. The trailing [aiobotocore] is
+# not just pulling in aiobotocore itself, but also pulls in all of the Amazon-provider's
+# extras, including the bits that power AWS SSO support. The AWS SSO hook in the Amazon
+# provider depends on the Python xmlsec library under the hood (to handle SAML digital
+# signatures). So we need xmlsec installed.
+#
+# Our pip is pointed to Dwolla's hosted PyPI artifact repository, and we don't have a
+# wheel for xmlsec. Public PyPI (https://pypi.org/project/xmlsec/) has wheels for Mac
+# and Windows, but not Linux. Because Linux distributions are so diverse, it's common
+# for Linux wheels to be unavailable and require building from source. This is common
+# for packages like xmlsec. Because of this we need to build xmlsec from source.
+#
+# In addition to this, the Python xmlsec package are binding to the C library, not the C
+# library itself. So we need to build and install the C library too. This script
+# installs the C library. The C library requires all of the dependencies listed below.
+#
+# Difference between <lib> and <lib>-dev:
+# libxml2 is for running software that uses libxml2.
+# libxml2-dev is for building or compiling software against libxml2 (which is the
+# case for building Python wheels for packages like xmlsec).
+#
+# After installing, the `rm` cleans up the local repository of retrieved package files.
+# This reduces the size of the Docker image by removing unnecessary cached files after
+# installation.

+
+# Explanation for this section:
+# Because we need xmlsec from above there is a specific issue with getting xmlsec that
+# we address here. We need to build and install xmlsec1 v1.3.x because when running
+# apt-get for xmlsec1, version 1.3.7 is currently only available in the Debian
+# experimental repository, not in the stable repository. The main Debian and Ubuntu
+# distributions are still using 1.2.x versions. According to the Debian Package Tracker,
+# version 1.3.7-1 was only accepted into experimental on March 25, 2025, with standard
+# repositories still using 1.2.41-1.
+#
+# The public PyPI xmlsec wrapper (v1.3.x) expects newer C header files (including
+# xmlSecKeyDataFormatEngine) introduced in the 1.3.x series. So we need to build and
+# install the 1.3.x series. This whole script is temporary and can be removed once these
+# packages are updated in Linux and/or the Jenkins image.
