Adrien Destugues f15516ff92 Package Kit: re-use downloads from unfinished transactions
There are three parts to this change:
- In FetchFileJob, if the request fails with a timeout or IO error
  (probably because of unstable connection) attempt to resume the
  download with a range request. No limit on number of retries
  currently, maybe we should add one.
- In PackageManager, before downloading a file, look around in other
  transaction directories in case it's already there. Partial and
  complete downloads are differentiated by an attribute which the
  fetch file job maintains. For complete downloads, no fetch job is
  scheduled, for partial downloads, the fetch job will request the
  remainder of the file.
- In BHttpRequest, the implementation of SetRangeStart() and
  SetRangeEnd() have been added, along with some refactoring to
  handle listener notifications consistently. This also fixed a
  bug where the final notification for download progress was not
  emitted for compressed data.

Fixes #12414.

Haiku

Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs

Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

Goals

  • Sensible defaults with minimal configuration required.
  • Clean, clear, concise code.
  • Unified desktop environment.

Trying Haiku

Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.

Compiling Haiku

See ReadMe.Compiling.
