  • Gitea version (or commit ref): 1.12.2
  • Git version: 2.26.2
  • Operating system: Fedora 32
  • Database (use [x]):
    • PostgreSQL
    • MySQL
    • MSSQL
    • SQLite
  • Can you reproduce the bug at https://try.gitea.io:
    • Yes (provide example URL)
    • No
    • Not relevant

Description

gitea dump -c /etc/gitea/app.ini uses /tmp to temporarily store the zip dump. This method is broken once the zip is larger than half of memory since modern OS uses tmpfs for /tmp which has a capacity of equal to half of memory. According to the documentation, /var/tmp can be used for large files.

There is a --tempdir option to set this to whatever is required:
