Userspace utilities to manage btrfs filesystems. License: GPLv2.
Btrfs is a copy on write (COW) filesystem for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration.
This repository hosts following utilities:
The C and python 3 bindings are provided by a LGPL library libbtrfsutil see libbtrfsutil/README.md for more.
The major version releases are time-based and follow the cycle of the linux kernel releases. The cycle usually takes 2 months. A minor version releases may happen in the meantime if there are bug fixes or minor useful improvements queued.
There are several ways, each has its own specifics and audience that can give feedback or work on a fix. The following list is sorted in the order of preference:
The patch submissions, development or general discussions take place at firstname.lastname@example.org mailinglist, subsciption is not required to post.
The GitHub pull requests will not be accepted directly, the preferred way is to send patches to the mailinglist instead. You can link to a branch in any git repository if the mails do not make it to the mailinglist or just for convenience (makes it easier to test).
The development model of btrfs-progs shares a lot with the kernel model. The github way is different in some ways. We, the upstream community, expect that the patches meet some criteria (often lacking in github contributions):
git log --onelinefor some inspiration
Source code coding style and preferences follow the
kernel coding style.
You can find the editor settins in
.editorconfig and use the
EditorConfig plugin to let your editor use that,
or update your editor settings manually.
Documentation fixes or updates do not need much explanation so sticking to the code rules in the previous section is not necessary. GitHub pull requests are OK, patches could be sent to me directly and not required to be also in the mailinglist. Pointing out typos via IRC also works, although might get accidentally lost in the noise.
Build dependencies are listed in INSTALL. Implementation of checksum/hash functions is provided by copies of the respective sources to avoid adding dependencies that would make deployments in rescure or limited environments harder. The implementations are portable and not optimized for speed nor accelerated. Optionally it's possible to use libgcrypt, libsodium or libkcapi implementations.
