- if task_key + "_o.h5" not in os.listdir(cache_directory):+ output_path = os.path.join(cache_directory, f"{task_key}_o.h5")+ if not os.path.exists(output_path):

You already compute the same path a few lines later; reuse it to keep the logic DRY.

🛠️ Refactor suggestion

Prefer os.path.exists() over directory scans for existence checks

Using task_key + "_o.h5" not in os.listdir(cache_directory) forces a full directory listing on every call.
os.path.exists(file_name) (or Path(file_name).exists()) is:

  1. O(1) rather than O(n) on large cache dirs.
  2. Immune to race conditions where a file is created between listdir() and the subsequent logic.
  3. Clearer to read.
- file_name = os.path.join(cache_directory, task_key + "_o.h5")- if task_key + "_o.h5" not in os.listdir(cache_directory):+ file_name = os.path.join(cache_directory, f"{task_key}_o.h5")+ if not os.path.exists(file_name):

In executorlib/task_scheduler/interactive/shared.py around lines 154 to 156,
replace the check using 'task_key + "_o.h5" not in os.listdir(cache_directory)'
with 'not os.path.exists(file_name)'. This avoids scanning the entire directory,
improves performance, prevents race conditions, and makes the code clearer by
directly checking the file's existence.

Prefer os.path.exists() over directory scans for existence checks

Using task_key + "_o.h5" not in os.listdir(cache_directory) forces a full directory listing on every call.
os.path.exists(file_name) (or Path(file_name).exists()) is:

  1. O(1) rather than O(n) on large cache dirs.
  2. Immune to race conditions where a file is created between listdir() and the subsequent logic.
  3. Clearer to read.
- file_name = os.path.join(cache_directory, task_key + "_o.h5")- if task_key + "_o.h5" not in os.listdir(cache_directory):+ file_name = os.path.join(cache_directory, f"{task_key}_o.h5")+ if not os.path.exists(file_name):

replace the check using 'task_key + "_o.h5" not in os.listdir(cache_directory)'
with 'not os.path.exists(file_name)'. This avoids scanning the entire directory,
improves performance, prevents race conditions, and makes the code clearer by

🛠️ Refactor suggestion

Use exists() instead of scanning the directory for every task

Similar to the interactive path, scanning os.listdir(cache_directory) for each task does an unnecessary O(n) walk and risks TOCTOU issues.

- if task_key + "_o.h5" not in os.listdir(cache_directory):+ output_path = os.path.join(cache_directory, f"{task_key}_o.h5")+ if not os.path.exists(output_path):

You already compute the same path a few lines later; reuse it to keep the logic DRY.

Use exists() instead of scanning the directory for every task

Similar to the interactive path, scanning os.listdir(cache_directory) for each task does an unnecessary O(n) walk and risks TOCTOU issues.

- if task_key + "_o.h5" not in os.listdir(cache_directory):+ output_path = os.path.join(cache_directory, f"{task_key}_o.h5")+ if not os.path.exists(output_path):

You already compute the same path a few lines later; reuse it to keep the logic DRY.

the check that scans os.listdir(cache_directory) with a direct file existence
check using os.path.exists() for the target file to avoid inefficient directory
scans and TOCTOU issues. Also, reuse the computed file path variable instead of
reconstructing it to keep the code DRY.

🛠️ Refactor suggestion

Prefer os.path.exists() over directory scans for existence checks

Using task_key + "_o.h5" not in os.listdir(cache_directory) forces a full directory listing on every call.
os.path.exists(file_name) (or Path(file_name).exists()) is:

  1. O(1) rather than O(n) on large cache dirs.
  2. Immune to race conditions where a file is created between listdir() and the subsequent logic.
  3. Clearer to read.
- file_name = os.path.join(cache_directory, task_key + "_o.h5")- if task_key + "_o.h5" not in os.listdir(cache_directory):+ file_name = os.path.join(cache_directory, f"{task_key}_o.h5")+ if not os.path.exists(file_name):

In executorlib/task_scheduler/interactive/shared.py around lines 154 to 156,
replace the check using 'task_key + "_o.h5" not in os.listdir(cache_directory)'
with 'not os.path.exists(file_name)'. This avoids scanning the entire directory,
improves performance, prevents race conditions, and makes the code clearer by
directly checking the file's existence.

🛠️ Refactor suggestion

Prefer os.path.exists() over directory scans for existence checks

Using task_key + "_o.h5" not in os.listdir(cache_directory) forces a full directory listing on every call.
os.path.exists(file_name) (or Path(file_name).exists()) is:

  1. O(1) rather than O(n) on large cache dirs.
  2. Immune to race conditions where a file is created between listdir() and the subsequent logic.
  3. Clearer to read.
- file_name = os.path.join(cache_directory, task_key + "_o.h5")- if task_key + "_o.h5" not in os.listdir(cache_directory):+ file_name = os.path.join(cache_directory, f"{task_key}_o.h5")+ if not os.path.exists(file_name):

improves performance, prevents race conditions, and makes the code clearer by

🛠️ Refactor suggestion

Use exists() instead of scanning the directory for every task

Similar to the interactive path, scanning os.listdir(cache_directory) for each task does an unnecessary O(n) walk and risks TOCTOU issues.

- if task_key + "_o.h5" not in os.listdir(cache_directory):+ output_path = os.path.join(cache_directory, f"{task_key}_o.h5")+ if not os.path.exists(output_path):

You already compute the same path a few lines later; reuse it to keep the logic DRY.

the check that scans os.listdir(cache_directory) with a direct file existence
check using os.path.exists() for the target file to avoid inefficient directory
scans and TOCTOU issues. Also, reuse the computed file path variable instead of
reconstructing it to keep the code DRY.

🛠️ Refactor suggestion

Prefer os.path.exists() over directory scans for existence checks

Using task_key + "_o.h5" not in os.listdir(cache_directory) forces a full directory listing on every call.
os.path.exists(file_name) (or Path(file_name).exists()) is:

  1. O(1) rather than O(n) on large cache dirs.
  2. Immune to race conditions where a file is created between listdir() and the subsequent logic.
  3. Clearer to read.
- file_name = os.path.join(cache_directory, task_key + "_o.h5")- if task_key + "_o.h5" not in os.listdir(cache_directory):+ file_name = os.path.join(cache_directory, f"{task_key}_o.h5")+ if not os.path.exists(file_name):

In executorlib/task_scheduler/interactive/shared.py around lines 154 to 156,
replace the check using 'task_key + "_o.h5" not in os.listdir(cache_directory)'
with 'not os.path.exists(file_name)'. This avoids scanning the entire directory,
improves performance, prevents race conditions, and makes the code clearer by
directly checking the file's existence.

In executorlib/task_scheduler/file/shared.py around lines 111 to 114, replace
the check that scans os.listdir(cache_directory) with a direct file existence
check using os.path.exists() for the target file to avoid inefficient directory
scans and TOCTOU issues. Also, reuse the computed file path variable instead of
reconstructing it to keep the code DRY.

🛠️ Refactor suggestion

Prefer os.path.exists() over directory scans for existence checks

Using task_key + "_o.h5" not in os.listdir(cache_directory) forces a full directory listing on every call.
os.path.exists(file_name) (or Path(file_name).exists()) is:

  1. O(1) rather than O(n) on large cache dirs.
  2. Immune to race conditions where a file is created between listdir() and the subsequent logic.
  3. Clearer to read.
- file_name = os.path.join(cache_directory, task_key + "_o.h5")- if task_key + "_o.h5" not in os.listdir(cache_directory):+ file_name = os.path.join(cache_directory, f"{task_key}_o.h5")+ if not os.path.exists(file_name):

In executorlib/task_scheduler/interactive/shared.py around lines 154 to 156,
replace the check using 'task_key + "_o.h5" not in os.listdir(cache_directory)'
with 'not os.path.exists(file_name)'. This avoids scanning the entire directory,
improves performance, prevents race conditions, and makes the code clearer by
directly checking the file's existence.
