Error Messages and Platform

Oct 13, 2025 by pynkocean.com 22 views

Introduction

In recent times, two crucial Linux-as-Cran jobs, namely ubuntu-next and ubuntu-release, have been experiencing failures due to the presence of leftover directories. These directories, .cache and .local, are not being properly cleaned up after the build and testing processes. This issue is peculiar as it does not occur in other job varieties such as ubuntu-clang and clang20. In this article, we will delve into the details of this problem, explore possible causes, and discuss potential solutions.

Describe the Bug

The bug manifests itself in the form of a failure in the ubuntu-next and ubuntu-release jobs. Upon closer inspection, it becomes apparent that the root cause of the issue lies in the presence of two directories, .cache and .local, which are not being deleted after the build and testing processes. This results in a significant amount of disk space being occupied by these directories, leading to the failure of the jobs.

Error Messages and Platform

The error messages associated with this bug are not particularly informative, but they do provide some clues about the nature of the problem. The error messages indicate that the total disk space occupied by the directories is approximately 40K and 48K, respectively. This suggests that the issue is not related to a lack of disk space, but rather to the presence of these directories.

The platform on which this bug is occurring is Linux, specifically Ubuntu. The version of Ubuntu being used is not specified, but it is likely a recent version.

Component(s)

The components involved in this bug are:

Continuous Integration: This is the process of automatically building and testing software code changes. In this case, the Continuous Integration process is failing due to the presence of leftover directories.
R: This is the programming language being used to build and test the software.

Possible Causes

There are several possible causes for this bug:

Incorrect cleanup scripts: It is possible that the cleanup scripts being used to delete the directories are not functioning correctly. This could be due to a variety of reasons, including incorrect permissions or incorrect directory paths.
Directory permissions: The permissions on the directories may be preventing them from being deleted. This could be due to a variety of reasons, including incorrect ownership or incorrect permissions.
Directory contents: The contents of the directories may be preventing them from being deleted. This could be due to a variety of reasons, including incorrect file permissions or incorrect file ownership.

Potential Solutions

There are several potential solutions to this bug:

Modify the cleanup scripts: The cleanup scripts being used to delete the directories may need to be modified to function correctly. This could involve changing the directory paths, changing the permissions, or changing the contents of the directories.
Change directory permissions: The permissions on the directories may need to be changed to allow them to be deleted. This could involve changing the ownership or changing the permissions.
Delete directory contents: The contents of the directories may need to be deleted to allow the directories to be deleted. This could involve deleting the files or deleting the subdirectories.

Conclusion

In conclusion, the two Linux-as-Cran jobs, ubuntu-next and ubuntu-release, are failing due to the presence of leftover directories. The directories, .cache and .local, are not being properly cleaned up after the build and testing processes. This issue is peculiar as it does not occur in other job varieties. The possible causes of this bug include incorrect cleanup scripts, directory permissions, and directory contents. The potential solutions to this bug include modifying the cleanup scripts, changing directory permissions, and deleting directory contents.
