Created by: ghost

  1. Summary: Gitlab 7.7.2 ActionView component returns an Error 500 irelated to UTF8 encoding whenever it encounters a special character like 'ç'.
  2. Steps to reproduce: This issue happens when trying to perform the following actions
    • Displaying the file tree of a Branch
    • Displaying the commit list of the branch
    • Displaying the network of a branch
    • Displaying the the graph of a branch
    • Displaying the compare new merge request page
  3. Displaying File Tree:
    • Expected behavior: displying the file tree of a branch including commits data.
    • Observed behavior: The commit data column keep displaying "loading data" message
    • Relevant logs: Processing by Projects::RefsController#logs_tree as JS Parameters: {"_"=>"1422632454051", "project_id"=>"apis/api-exposure-layer", "id"=>"master"} Completed 500 Internal Server Error in 325ms ActionView::Template::Error (invalid byte sequence in UTF-8): 1: %span.str-truncated 2: %span.tree_author= commit_author_link(commit, avatar: true, size: 16) 3: = link_to_gfm commit.title, project_commit_path(@project, commit.id), class: "tree-commit-link" This seems to suggest that the (invalid byte sequence in UTF-8) is located
  4. Displaying compare branches in merge request:

  5. Displaying the commit list of the branch:
    • Expected behavior: displying the list of commits of a branch
    • Observed behavior: The commit data column keep displaying "loading data" message
