Use dynamic AWX max_workers value Make basic --status and --running commands work Make feature flag enabled true by default for development * [dispatcherd] Dispatcher socket-based `--status` demo working (#15908) * Fix Task Decorator to Work With and Without Feature Flag (AAP-41775) (#15911) * refactor(system): extract common heartbeat helpers and split cluster_node_heartbeat Extract common heartbeat logic into helper functions: _heartbeat_instance_management: consolidates instance management, health checks, and lost-instance detection. _heartbeat_check_versions: compares instance versions and initiates shutdown when necessary. _heartbeat_handle_lost_instances: reaps jobs and marks lost instances offline. Refactor the original cluster_node_heartbeat to use these helpers and retain legacy behavior (using bind_kwargs). Introduce adispatch_cluster_node_heartbeat for dispatcherd: uses the control API to retrieve running tasks and reaps them. Link the two implementations by attaching adispatch_cluster_node_heartbeat as the _new_method on cluster_node_heartbeat. * feat(publish): delegate heartbeat task submission to new dispatcherd implementation Update apply_async to check at runtime if FEATURE_NEW_DISPATCHER is enabled. When the task is cluster_node_heartbeat and a _new_method is attached, delegate the task submission to the new dispatcherd implementation. Preserve the original behavior for all other tasks and fallback on error. * refactor(system): extract task ID retrieval from dispatcherd into helper function Improves readability of adispatch_cluster_node_heartbeat by extracting the complex UUID parsing logic into a dedicated helper function. Adds clearer error handling and follows established code patterns. * fix(dispatcher): Enable task decorator to work with and without feature flag Implemented a new approach for handling task execution with feature flags by attaching alternative implementations to apply_async._new_method. This allows cluster_node_heartbeat to work correctly with both the legacy and new dispatcher systems without modifying core decorator logic. AAP-41775 * fix(dispatcher): Improve error handling and logging in feature flag implementation - Add error handling when attaching alternative dispatcher implementation - Fix method self-reference in apply_async to properly use cls.apply_async - Document limitations of this targeted approach for specific tasks - Add logging for better debugging of dispatcher selection - Ensure decorator timing by keeping method attachment after function definitions This completes the robust implementation for switching between dispatcher implementations based on feature flags. AAP-41775 * fix(dispatcher): Implement registry pattern for dispatcher feature flag compatibility Replaces direct method attribute assignment with a global registry for alternative implementations. The original approach tried to attach new methods directly to apply_async bound methods, which fails because bound methods don't support attribute assignment in Python. The registry pattern: - Creates a global ALTERNATIVE_TASK_IMPLEMENTATIONS dict in publish.py - Registers alternative implementations by task name - Modifies apply_async to check the registry when feature flag is enabled - Adds extensive logging throughout the process for debugging This enables cluster_node_heartbeat to work correctly with both the legacy and new dispatcher implementations based on the FEATURE_NEW_DISPATCHER flag. AAP-41775 * refactor(dispatcher): Remove excessive logging from dispatcher implementation Reduces verbose debugging logs while maintaining essential logging for critical operations. Preserves: - Task implementation selection based on feature flag - Registration success/failure messages - Critical error reporting Removed: - Registry content debugging messages - Repetitive task diagnostics - Non-essential information logging AAP-41775 * fix(dispatcher): Fix shallow copy in dispatcher schedule conversion This resolves "AttributeError: 'float' object has no attribute 'total_seconds'" errors when the dispatcher is restarted. Refs: AAP-41775 * Use IPC mechanism to get running tasks (#15926) * Allow tasks from tasks * Fix failure to limit to waiting jobs * Get job record with lock * Fix failures in dispatcherd feature branch (#15930) * Fully handle DispatcherCancel * Complete rest of preload import work * Complete dispatcherd integration & job cancellation (AAP-43033) (#15941) * feat(dispatcher): Implement job cancellation for new dispatcher Adds feature-flag-aware job cancellation that routes cancel requests to either the legacy dispatcher or the new dispatcherd library based on the FEATURE_NEW_DISPATCHER flag. - Updates cancel_dispatcher_process() to use dispatcherd's control API when enabled - Handles both direct cancellation and task manager workflow cancellation cases - Works with DispatcherCancel exception handling to properly handle SIGUSR1 signals AAP-43033 * fix(dispatcher): Update run_dispatcher.py to properly handle task cancellation Modifies the cancel command in run_dispatcher.py to properly cancel tasks when the FEATURE_NEW_DISPATCHER flag is enabled, rather than just listing running tasks. The implementation translates each task UUID to the appropriate filter format expected by the dispatcherd control API, maintaining the same behavior as the original implementation. Part of: AAP-43033 * refactor(system): Refactor dispatch_startup() to extract common startup logic and branch based on feature flag This commit refactors the dispatch_startup() function to improve clarity and consistency across the legacy and new dispatcherd flows. No dispatcher-specific functionality is needed beyond the changes made, so this refactoring improves robustness without altering core behavior. * refactor(system): Refactor inform_cluster_of_shutdown() for clarity * refactor(tasks): Replace @task with @task_awx across 22 tasks for dispatcher compatibility - Migrated all task decorators to use @task_awx, ensuring dispatcher-aware behavior. - Tested each task with the new dispatcherd, verifying that tasks using the registry pattern execute correctly without needing binder‐based alternative implementations. - Removed redundant logging and outdated comments. - Legacy tasks that do not require special parameter extraction continue to use their original logic. - This commit reflects our complete journey of testing and verifying dispatcherd compatibility across all 22 tasks. * refactor(publish): fix linter * Fix bug from the branch rebase * AAP-43763 Add tests for connection management in dispatcherd workers (#15949) * Add test for job cancel in live tests * Fix bug from the branch rebase * Add test for connection recovery after connection broke * Add test for breaking connection * Fix dispatcherd bugs: schedule aliases, job kwargs handling, cancel handling (#15960) * Put in job kwargs handling, not done before * AAP-44382 [dispatcherd] Fixes for running with feature flag off (#15973) * Use correct decorator for test of tasks * Finalize dispatcherd feature branch (#15975) * Work dispatcherd into dependency management system * Use util methods from DAB * Rename the dispatcherd feature flag, and flip default to not-enabled * Move to new submit_task method * Update the location of the sock file * AAP-44381 Make dispatcherd config loading more lazy (#15979) * Make dispatcherd config loading more lazy * Make submission error more obvious * Fix signal handling gap, hijack SIGUSR1 from dispatcherd (#15983) * Fix signal handling gap, hijack SIGUSR1 from dispatcherd * Minor adjustments to dispatcherd status command * [dispatcherd] Get rid of alternative task registry (#15984) Get rid of alternative task registry * Fix deadlock error and other cleanup errors (#15987) * Move to proper error handling location --------- Co-authored-by: artem_tiupin <70763601+art-tapin@users.noreply.github.com>
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 <pypi library name> -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-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.
Verify ansible-runner's build dependency doesn't conflict with the changes made.
cryptography
If modifying this library make sure testing with the offline build is performed to confirm it is functionally working.
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.
