# Dependency Management The `requirements.txt` file is generated from `requirements.in` and `requirements_git.txt`, using `pip-tools` and `pip-compile`. ## How To Use Commands should be run in the awx container from inside the `./requirements` directory of the awx repository. ### Upgrading or Adding Select Libraries If you need to add or upgrade one targeted library, then modify `requirements.in`, then run the script: `./updater.sh run` #### Upgrading Unpinned Dependency If you require a new version of a dependency that does not have a pinned version for a fix or feature, pin a minimum version in `requirements.in` and run `./updater.sh run`. For example, replace the line `asgi-amqp` with `asgi-amqp>=1.1.4`, and consider leaving a note. Then next time that a general upgrade is performed, the minimum version specifiers can be removed, because `*.txt` files are upgraded to latest. ### Upgrading Dependencies You can upgrade (`pip-compile --upgrade`) the dependencies by running `./updater.sh upgrade`. ## Licenses and Source Files If any library has a change to its license with the upgrade, then the license for that library inside of `licenses` needs to be updated. For libraries that have source distribution requirements (LGPL as an example), a tarball of the library is kept along with the license. To download the PyPI tarball, you can run this command: ``` pip download -d licenses/ --no-binary :all: --no-deps ``` Make sure to delete the old tarball if it is an upgrade. ## UPGRADE BLOCKERs Anything pinned in `*.in` files involves additional manual work in order to upgrade. Some information related to that work is outlined here. ### django-split-settings When we attemed to upgrade past 1.0.0 the build process in GitHub failed on the docker build step with the following error: ``` #19 [builder 12/12] RUN AWX_SETTINGS_FILE=/dev/null SKIP_SECRET_KEY_CHECK=yes SKIP_PG_VERSION_CHECK=yes /var/lib/awx/venv/awx/bin/awx-manage collectstatic --noinput --clear #19 sha256:cd5adb08d3aa92504348338475db9f8bb820b4f67ba5b75edf9ae7554175f1d0 #19 0.725 Traceback (most recent call last): #19 0.725 File \"/var/lib/awx/venv/awx/bin/awx-manage\", line 8, in #19 0.726 sys.exit(manage()) #19 0.726 File \"/var/lib/awx/venv/awx/lib64/python3.9/site-packages/awx/__init__.py\", line 178, in manage #19 0.726 prepare_env() #19 0.726 File \"/var/lib/awx/venv/awx/lib64/python3.9/site-packages/awx/__init__.py\", line 133, in prepare_env #19 0.726 if not settings.DEBUG: # pragma: no cover #19 0.726 File \"/var/lib/awx/venv/awx/lib64/python3.9/site-packages/django/conf/__init__.py\", line 82, in __getattr__ #19 0.726 self._setup(name) #19 0.726 File \"/var/lib/awx/venv/awx/lib64/python3.9/site-packages/django/conf/__init__.py\", line 69, in _setup #19 0.726 self._wrapped = Settings(settings_module) #19 0.726 File \"/var/lib/awx/venv/awx/lib64/python3.9/site-packages/django/conf/__init__.py\", line 170, in __init__ #19 0.726 mod = importlib.import_module(self.SETTINGS_MODULE) #19 0.726 File \"/usr/lib64/python3.9/importlib/__init__.py\", line 127, in import_module #19 0.726 return _bootstrap._gcd_import(name[level:], package, level) #19 0.726 File \"\", line 1030, in _gcd_import #19 0.726 File \"\", line 1007, in _find_and_load #19 0.726 File \"\", line 986, in _find_and_load_unlocked #19 0.726 File \"\", line 680, in _load_unlocked #19 0.726 File \"\", line 850, in exec_module #19 0.726 File \"\", line 228, in _call_with_frames_removed #19 0.726 File \"/var/lib/awx/venv/awx/lib64/python3.9/site-packages/awx/settings/production.py\", line 74, in #19 0.726 include(settings_file, optional(settings_files), scope=locals()) #19 0.726 File \"/var/lib/awx/venv/awx/lib64/python3.9/site-packages/split_settings/tools.py\", line 116, in include #19 0.726 module = module_from_spec(spec) # type: ignore #19 0.726 File \"\", line 562, in module_from_spec #19 0.726 AttributeError: 'NoneType' object has no attribute 'loader' #19 ERROR: executor failed running [/bin/sh -c AWX_SETTINGS_FILE=/dev/null SKIP_SECRET_KEY_CHECK=yes SKIP_PG_VERSION_CHECK=yes /var/lib/awx/venv/awx/bin/awx-manage collectstatic --noinput --clear]: exit code: 1 ``` The various versions past 1.0.0 talk about adding and removing support for different python versions so there may be a mismatch in what the versions of the library support vs what is being built inside the container. Ironically, we did not experience the problem on our local containers when running `collectstatic` so we think it has something to do specifically with the build process. This issue was not picked up by any existing QE testing, only when building in GitHub. ### social-auth-app-django django-social keeps a list of backends in memory that it gathers based on the value of `settings.AUTHENTICATION_BACKENDS` *at import time*: https://github.com/python-social-auth/social-app-django/blob/c1e2795b00b753d58a81fa6a0261d8dae1d9c73d/social_django/utils.py#L13 Our `settings.AUTHENTICATION_BACKENDS` can *change* dynamically as settings are changed (i.e., if somebody configures Github OAuth2 integration), so we need to _overwrite_ this in-memory value at the top of every request so that we have the latest version ### django-oauth-toolkit Versions later than 1.4.1 throw an error about id_token_id, due to the OpenID Connect work that was done in https://github.com/jazzband/django-oauth-toolkit/pull/915. This may be fixable by creating a migration on our end? ### pip, setuptools and setuptools_scm If modifying these libraries make sure testing with the offline build is performed to confirm they are functionally working. Versions need to match the versions used in the pip bootstrapping step in the top-level Makefile. ### cryptography If modifying this library make sure testing with the offline build is performed to confirm it is functionally working. ### channels-redis Due to an upstream bug (linked below), we see `RuntimeError: Event loop is closed` errors with newer versions of `channels-redis`. Upstream is aware of the bug and it is likely to be fixed in the next release according to the issue linked below. For now, we pin to the old version, 3.4.1 * https://github.com/django/channels_redis/issues/332 * https://github.com/ansible/awx/issues/13313 ### hiredis The hiredis 2.1.0 release doesn't provide source distribution on PyPI which prevents users to build that python package from the sources. Downgrading to 2.0.0 (which provides source distribution) until the channels-redis issue is fixed or a newer hiredis version is available on PyPi with source distribution. * https://github.com/redis/hiredis-py/issues/138 ## Library Notes ### pexpect Version 4.8 makes us a little bit nervous with changes to `searchwindowsize` https://github.com/pexpect/pexpect/pull/579/files Pin to `pexpect==4.7.x` until we have more time to move to `4.8` and test.
