picoshare

This release drastically improves PicoShare's performance. In tests, it runs stable on a shared CPU VM with only 256 MB of RAM, accepting uploads of over 1 GB.

New Features

• Display upload progress by @mtlynch in https://github.com/mtlynch/picoshare/pull/305, https://github.com/mtlynch/picoshare/pull/308
• SQLite VACUUMing is now controlled by the command-line flag -vacuum @mtlynch in https://github.com/mtlynch/picoshare/pull/306

Improvements

• Improve performance for file downloads, especially with streaming content by @mtlynch in https://github.com/mtlynch/picoshare/pull/285
• Use less RAM while processing uploads by @mtlynch in https://github.com/mtlynch/picoshare/pull/287, https://github.com/mtlynch/picoshare/pull/293
• Free multipart resources after reading them by @mtlynch in https://github.com/mtlynch/picoshare/pull/289

Breaking Changes

• Periodic SQLite VACUUMing is now off by default
  • You can enable VACUUMing with the -vacuum command line flag.
  • VACUUM reclaims disk space as you delete files from PicoShare, but it increases RAM usage, especially when PicoShare is running with Litestream enabled.
