⚠️ Potential issue

Potential IndexError when accessing previous build ID

In check_build_dependencies, lines 142-143 calculate previous_build_id using app_build_ids[app_build_ids.index(new_build.id) + 1]. If new_build.id is the last element in app_build_ids, this will result in an IndexError. Additionally, if new_build.id is not in app_build_ids, a ValueError will be raised.

Modify the code to handle these edge cases safely:

    if len(app_build_ids) > 1:
        try:
            idx = app_build_ids.index(new_build.id)
            if idx + 1 < len(app_build_ids):
                previous_build_id = app_build_ids[idx + 1]
                previous_build = get_app(new_build.domain, previous_build_id)
                last_build_has_dependencies = has_dependencies(previous_build) if previous_build else False
        except (ValueError, IndexError):
            # Handle the case where new_build.id is not found or is the last element
            last_build_has_dependencies = False

@Charl1996 Would you like me to help you implement the suggested fix to handle the edge cases safely? Let me know if you need any assistance.

No, it's fine. I don't think this will be a concern because the docstring in the get_build_ids says the following:
"Returns all the built apps for an application id, in descending order of time built."

I've verified that it's indeed so, meaning

  1. the new_build.id will definitely exist in the list
  2. if it's the last item in the list it also means its the only item in the list and the len(app_build_ids) will evaluate to false, meaning this block of code won't execute in the first place.

@Charl1996 I've found the implementation in dbaccessors.py and can confirm your explanation. The docstring indeed explicitly states that it "Returns all the built apps for an application id, in descending order of time built." This validates your assessment of the code's safety. Thank you for helping me understand the implementation better.

🔗 Analysis chain

@Charl1996 Thank you for the detailed explanation. I understand now that the code is indeed safe due to the guarantees provided by get_build_ids. Your explanation makes perfect sense - since the builds are returned in descending order and the new build will always be present, we don't need additional error handling.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Search for the implementation of get_build_ids
ast-grep --pattern 'def get_build_ids'

# Also search for any documentation or comments about get_build_ids
rg -A 5 'def get_build_ids'

PR: dimagi/commcare-hq#35628
File: corehq/apps/app_manager/tasks.py:142-143
Timestamp: 2025-01-20T08:22:44.938Z
Learning: The `get_build_ids` function in corehq.apps.app_manager.dbaccessors returns all built apps for an application ID in descending order of build time, which guarantees that:
1. A newly built app's ID will always exist in the returned list
2. If the new build ID is the last item in the list, it means it's the only item, preventing any IndexError in the `check_build_dependencies` function

I agree this shouldn't be an issue, but you could save readers from going through the same thought process you outlined, and make it obvious that isn't an issue, by doing something like:

build_index = app_build_ids.index(new_build.id)
if build_index < len(app_build_ids):
    previous_build_id = app_build_ids[build_index + 1]

Seems like the humans are having a chat. I'll hop back into my burrow for now. If you need me again, just tag @coderabbitai in a new comment, and I'll come hopping out!
