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:
|
|
|
|
* **btrfs** — the main administration tool ([manual page](https://btrfs.wiki.kernel.org/index.php/Manpage/btrfs))
|
|
* **mkfs.btrfs** — utility to create the filesystem ([manual page](https://btrfs.wiki.kernel.org/index.php/Manpage/mkfs.btrfs))
|
|
|
|
See INSTALL for build instructions and [tests/README.md](tests/README.md) for
|
|
testing information.

|
Release cycle
|
|
-------------
|
|
|
|
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.
|
|
|
|
The release tags are signed with a GPG key ID `F2B4 1200 C54E FB30 380C 1756 C565 D5F9 D76D 583B`,
|
|
release tarballs are hosted at [kernel.org](https://www.kernel.org/pub/linux/kernel/people/kdave/btrfs-progs/).
|
|
See file [CHANGES](CHANGES) or [changelogs on wiki](https://btrfs.wiki.kernel.org/index.php/Changelog#By_version_.28btrfs-progs.29).

Reporting bugs
|
|
--------------
|
|
|
|
There are several ways, each has its own specifics and audience that can give
|
|
feedback or work on a fix.
|
|
|
|
* [bugzilla.kernel.org](https://bugzilla.kernel.org) -- (requires
|
|
registration), set the product to Filesystems and component Btrfs, please put
|
|
'btrfs-progs' into the subject so it's clear that it's not a kernel bug
|
|
report
|
|
* to the mailing list *linux-btrfs@vger.kernel.org* -- (not required to
|
|
subscribe), beware that the mail might get overlooked in other traffic
|
|
* [github issue tracker](https://github.com/kdave/btrfs-sprogs/issues)
|
|
* IRC (irc.freenode.net #btrfs) -- good for discussions eg. if a bug is already
|
|
known, but reports could miss developers' attention
|
|
|
|
|
|
Development
|
|
-----------
|
|
|
|
The patch submissions, development or general discussions take place at
|
|
*linux-btrfs@vger.kernel.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):
|
|
|
|
* **one logical change per patch**: eg. not mixing bugfixes, cleanups, features
|
|
etc., sometimes it's not clear and will be usually pointed out during reviews
|
|
* proper **subject line**: eg. prefix with _btrfs-progs: subpart, ..._ ,
|
|
descriptive yet not too long, see `git log --oneline` for some inspiration
|
|
* proper **changelog**: the changelogs are often missing or lacking explanation _why_
|
|
the change was made, or _how_ is something broken, _what_ are user-visible
|
|
effects of the bug or the fix, _how_ does an improvement help or the intended
|
|
_usecase_
|
|
* the **Signed-off-by** line: this documents who authored the change, you can read
|
|
more about the _The Developer's Certificate of Origin_ [here (chapter 11)](https://www.kernel.org/doc/Documentation/SubmittingPatches)
|
|
|
|
**Exceptions**: documentation fixes or updates do not need much explanation so
|
|
sticking to the above rules is not necessary. Github pull requests are OK.
