Walkthrough

The condition for skipping redeployment of asset files in src/snakemake/assets/__init__.py was changed. Now, the redeployment is skipped if the asset's SHA256 is None or if the existing file's checksum matches the asset's SHA256, instead of only skipping when the checksum is present and matches.

Learning: In `snakemake/assets/__init__.py`, the `version` placeholders in asset URLs refer to the versions of external assets, not the Snakemake version. Therefore, these placeholders should not be flagged for version inconsistencies related to Snakemake.

File: src/snakemake/checkpoints.py:90-90
Timestamp: 2025-05-06T01:37:23.382Z
Learning: In Snakemake checkpoints implementation, tracking only the first missing output for each checkpoint is sufficient, because if one output is missing, all outputs for that checkpoint are considered incomplete. This was the behavior before PR #3562 and maintained in the pluralized `checkpoints.get()` implementation.

Timestamp: 2024-10-06T14:09:54.370Z
Learning: Changes made within test cases, such as in `tests/test_wrapper/Snakefile`, are for testing purposes and do not require updates to the project documentation.

File: snakemake/dag.py:1308-1308
Timestamp: 2024-10-14T09:42:11.571Z
Learning: In `snakemake/dag.py`, avoid flagging missing lines or indentation issues when there is no clear syntax or logical error to prevent false positives.

Timestamp: 2024-10-11T13:12:35.827Z
Learning: In the `snakemake/deployment/conda.py` file, within the `Env` class, validation of `env_dir` occurs later in the code, so it's unnecessary to validate `env_dir` in the `__init__` method.

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
