Introduction

This article addresses a critical bug encountered in OpenSlides, specifically related to meeting duplication when global fonts are linked within a template meeting. This issue prevents users from successfully duplicating meetings, impacting workflow and efficiency. This article aims to provide a comprehensive understanding of the bug, its reproduction steps, and the expected behavior. Understanding the root cause and the steps to reproduce the issue are crucial for developers and users alike, ensuring a smoother experience with OpenSlides. We will delve into the error messages, the context in which they appear, and the underlying problems that cause this malfunction. By highlighting this bug, we aim to contribute to the ongoing improvement and stability of OpenSlides, a vital tool for organizations relying on it for meeting management and presentations. The article will guide you through a step-by-step reproduction process, allowing you to witness the error firsthand and grasp the significance of the issue. Furthermore, we will explore the expected behavior in contrast to the observed error, shedding light on the discrepancy and the need for a resolution.

Bug Description

The bug manifests when a user attempts to duplicate a meeting that contains a folder with global fonts. These fonts are set as the default font within the template meeting. When the duplication process is initiated, an error occurs, preventing the meeting from being copied successfully. This issue stems from inconsistencies in the handling of media file relationships and permissions during the duplication process. The error message, as displayed in the snackbar, provides a high-level indication of the problem, but the console's network tab reveals more detailed information about the specific errors encountered. These errors often involve issues with the meeting_mediafile object, including relation errors, incorrect public visibility settings, and discrepancies in inherited access group IDs. The inability to duplicate meetings with linked fonts poses a significant challenge for organizations that rely on templates to maintain consistency across their meetings. It disrupts workflows and necessitates manual workarounds, which are time-consuming and prone to errors. Resolving this bug is crucial to ensuring the smooth operation of OpenSlides and its usability in real-world scenarios. This article will dissect the error messages, providing a clear explanation of each error component and its implication on the meeting duplication process. By understanding the specific errors, developers can target the root causes more effectively and implement robust solutions. Moreover, we will explore the potential impact of this bug on various user roles within an organization, from administrators to presenters, emphasizing the widespread implications of this seemingly localized issue. Understanding the depth and breadth of the problem is key to prioritizing its resolution and ensuring a seamless user experience.

Error Details

When the duplication process fails, the snackbar displays a generic error message, as shown in the provided image. However, the console's network tab provides a more granular view of the errors. The JSON response in the network tab reveals the following key issues:

  • meeting_mediafile/97/mediafile_id: This error indicates a relation issue, stating that the mediafile ID points to a specific mediafile but the reverse relation is corrupt. This suggests a problem in how the relationship between the meeting mediafile and the actual mediafile is being handled during the duplication process. The integrity of these relationships is crucial for ensuring that all associated files are correctly copied and linked within the new meeting. A corrupt reverse relation can lead to broken links, missing resources, and ultimately, a dysfunctional duplicated meeting. This error highlights the complexity of managing relationships between different entities within OpenSlides and the importance of maintaining data consistency during operations like duplication.
  • meeting_mediafile/97: is_public is wrong: This error highlights a discrepancy in the is_public flag for the mediafile. The error message indicates that the expected value (True) does not match the actual value (False). This can lead to access control issues in the duplicated meeting, potentially restricting access to certain resources that should be publicly available. The is_public flag plays a critical role in determining the visibility and accessibility of media files within OpenSlides. An incorrect setting can have significant implications for users who rely on these files for presentations or other meeting-related activities. Ensuring the correct setting is maintained during duplication is essential for preserving the intended access permissions.
  • meeting_mediafile/97: inherited_access_group_ids is wrong: This error indicates an issue with the inherited access group IDs. This suggests that the access permissions for the mediafile are not being correctly inherited in the duplicated meeting. Access groups play a vital role in controlling user access to different resources within OpenSlides. Incorrect inheritance of access group IDs can lead to unauthorized access or, conversely, prevent authorized users from accessing necessary files. This error underscores the complexity of managing access control in a collaborative environment and the importance of ensuring that permissions are correctly propagated during duplication. The correct assignment of access groups is crucial for maintaining security and data integrity within OpenSlides. This error highlights a potential vulnerability that could compromise the confidentiality and availability of meeting resources.

These errors collectively point to a problem in the way OpenSlides handles media files and their associated metadata during meeting duplication. The duplication process is failing to correctly replicate the relationships, permissions, and visibility settings of the media files, resulting in a broken duplicated meeting.

Steps to Reproduce

To reproduce this bug, follow these detailed steps:

  1. Open an OpenSlides instance: Start by accessing your OpenSlides instance. This could be a local development environment or a production instance, but it is crucial to ensure that the instance is running and accessible.
