[NETBEANS-2230] FileOwnerQuery should not scan vcs temporary files

• Type: Improvement
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 8.2
• Component/s: ide - Performance, projects - Generic Infrastructure, versioncontrol - Code

Description

During the opening of the file in the editor, DiffSidebar creates a temporary file. If a project is detected based on this file, then a new project will be created.

I tested it on 8.2, but I did not find any modifications in the current code regarding this issue.

BTW.: DiffSidebar came up when I solved why File System starts guarding the tmp directory in NETBEANS-168
