-bk-kernel-howto.txt: Description of kernel workflow under BitKeeper
-
-bk-make-sum: Create summary of changesets in one repository and not
-another, typically in preparation to be sent to an upstream maintainer.
-Typical usage:
- cd my-updated-repo
- bk-make-sum ~/repo/original-repo
- mv /tmp/linus.txt ../original-repo.txt
-
-bksend: Create readable text output containing summary of changes, GNU
-patch of the changes, and BK metadata of changes (as needed for proper
-importing into BitKeeper by an upstream maintainer). This output is
-suitable for emailing BitKeeper changes. The recipient of this output
-may pipe it directly to 'bk receive'.
-
-bz64wrap: helper script. Uncompressed input is piped to this script,
-which compresses its input, and then outputs the uu-/base64-encoded
-version of the compressed input.
-
-cpcset: Copy changeset between unrelated repositories.
-Attempts to preserve changeset user, user address, description, in
-addition to the changeset (the patch) itself.
-Typical usage:
- cd my-updated-repo
- bk changes # looking for a changeset...
- cpcset 1.1511 . ../another-repo
-
-csets-to-patches: Produces a delta of two BK repositories, in the form
-of individual files, each containing a single cset as a GNU patch.
-Output is several files, each with the filename "/tmp/rev-$REV.patch"
-Typical usage:
- cd my-updated-repo
- bk changes -L ~/repo/original-repo 2>&1 | \
- perl csets-to-patches
-
-cset-to-linus: Produces a delta of two BK repositories, in the form of
-changeset descriptions, with 'diffstat' output created for each
-individual changset.
-Typical usage:
- cd my-updated-repo
- bk changes -L ~/repo/original-repo 2>&1 | \
- perl cset-to-linus > summary.txt
-
-gcapatch: Generates patch containing changes in local repository.
-Typical usage:
- cd my-updated-repo
- gcapatch > foo.patch
-
-unbz64wrap: Reverse an encoded, compressed data stream created by
-bz64wrap into an uncompressed, typically text/plain output.

- Doing the BK Thing, Penguin-Style
-
-
-
-
-This set of notes is intended mainly for kernel developers, occasional
-or full-time, but sysadmins and power users may find parts of it useful
-as well. It assumes at least a basic familiarity with CVS, both at a
-user level (use on the cmd line) and at a higher level (client-server model).
-Due to the author's background, an operation may be described in terms
-of CVS, or in terms of how that operation differs from CVS.
-
-This is -not- intended to be BitKeeper documentation. Always run
-"bk help <command>" or in X "bk helptool <command>" for reference
-documentation.
-
-
-BitKeeper Concepts
-------------------
-
-In the true nature of the Internet itself, BitKeeper is a distributed
-system. When applied to revision control, this means doing away with
-client-server, and changing to a parent-child model... essentially
-peer-to-peer. On the developer's end, this also represents a
-fundamental disruption in the standard workflow of changes, commits,
-and merges. You will need to take a few minutes to think about
-how to best work under BitKeeper, and re-optimize things a bit.
-In some sense it is a bit radical, because it might described as
-tossing changes out into a maelstrom and having them magically
-land at the right destination... but I'm getting ahead of myself.
-
-Let's start with this progression:
-Each BitKeeper source tree on disk is a repository unto itself.
-Each repository has a parent (except the root/original, of course).
-Each repository contains a set of a changesets ("csets").
-Each cset is one or more changed files, bundled together.
-
-Each tree is a repository, so all changes are checked into the local
-tree. When a change is checked in, all modified files are grouped
-into a logical unit, the changeset. Internally, BK links these
-changesets in a tree, representing various converging and diverging
-lines of development. These changesets are the bread and butter of
-the BK system.
-
-After the concept of changesets, the next thing you need to get used
-to is having multiple copies of source trees lying around. This -really-
-takes some getting used to, for some people. Separate source trees
-are the means in BitKeeper by which you delineate parallel lines
-of development, both minor and major. What would be branches in
-CVS become separate source trees, or "clones" in BitKeeper [heh,
-or Star Wars] terminology.
-
-Clones and changesets are the tools from which most of the power of
-BitKeeper is derived. As mentioned earlier, each clone has a parent,
-the tree used as the source when the new clone was created. In a
-CVS-like setup, the parent would be a remote server on the Internet,
-and the child is your local clone of that tree.
-
-Once you have established a common baseline between two source trees --
-a common parent -- then you can merge changesets between those two
-trees with ease. Merging changes into a tree is called a "pull", and
-is analagous to 'cvs update'. A pull downloads all the changesets in
-the remote tree you do not have, and merges them. Sending changes in
-one tree to another tree is called a "push". Push sends all changes
-in the local tree the remote does not yet have, and merges them.
-
-From these concepts come some initial command examples:
-
-1) bk clone -q http://linux.bkbits.net/linux-2.5 linus-2.5
-Download a 2.5 stock kernel tree, naming it "linus-2.5" in the local dir.
-The "-q" disables listing every single file as it is downloaded.
-
-2) bk clone -ql linus-2.5 alpha-2.5
-Create a separate source tree for the Alpha AXP architecture.
-The "-l" uses hard links instead of copying data, since both trees are
-on the local disk. You can also replace the above with "bk lclone -q ..."
-
-You only clone a tree -once-. After cloning the tree lives a long time
-on disk, being updating by pushes and pulls.
-
-3) cd alpha-2.5 ; bk pull http://gkernel.bkbits.net/alpha-2.5
-Download changes in "alpha-2.5" repository which are not present
-in the local repository, and merge them into the source tree.
-
-4) bk -r co -q
-Because every tree is a repository, files must be checked out before
-they will be in their standard places in the source tree.
-
-5) bk vi fs/inode.c # example change...
- bk citool # checkin, using X tool
- bk push bk://gkernel@bkbits.net/alpha-2.5 # upload change
-Typical example of a BK sequence that would replace the analagous CVS
-situation,
- vi fs/inode.c
- cvs commit
-
-As this is just supposed to be a quick BK intro, for more in-depth
-tutorials, live working demos, and docs, see http://www.bitkeeper.com/
-
-
-
-BK and Kernel Development Workflow
-----------------------------------
-Currently the latest 2.5 tree is available via "bk clone $URL"
-and "bk pull $URL" at http://linux.bkbits.net/linux-2.5
-This should change in a few weeks to a kernel.org URL.
-
-
-A big part of using BitKeeper is organizing the various trees you have
-on your local disk, and organizing the flow of changes among those
-trees, and remote trees. If one were to graph the relationships between
-a desired BK setup, you are likely to see a few-many-few graph, like
-this:
-
- linux-2.5
- |
- merge-to-linus-2.5
- / | |
- / | |
- vm-hacks bugfixes filesys personal-hacks
- \ | | /
- \ | | /
- \ | | /
- testing-and-validation
-
-Since a "bk push" sends all changes not in the target tree, and
-since a "bk pull" receives all changes not in the source tree, you want
-to make sure you are only pushing specific changes to the desired tree,
-not all changes from "peer parent" trees. For example, pushing a change
-from the testing-and-validation tree would probably be a bad idea,
-because it will push all changes from vm-hacks, bugfixes, filesys, and
-personal-hacks trees into the target tree.
-
-One would typically work on only one "theme" at a time, either
-vm-hacks or bugfixes or filesys, keeping those changes isolated in
-their own tree during development, and only merge the isolated with
-other changes when going upstream (to Linus or other maintainers) or
-downstream (to your "union" trees, like testing-and-validation above).
-
-It should be noted that some of this separation is not just recommended
-practice, it's actually [for now] -enforced- by BitKeeper. BitKeeper
-requires that changesets maintain a certain order, which is the reason
-that "bk push" sends all local changesets the remote doesn't have. This
-separation may look like a lot of wasted disk space at first, but it
-helps when two unrelated changes may "pollute" the same area of code, or
-don't follow the same pace of development, or any other of the standard
-reasons why one creates a development branch.
-
-Small development branches (clones) will appear and disappear:
-
- -------- A --------- B --------- C --------- D -------
- \ /
- -----short-term devel branch-----
-
-While long-term branches will parallel a tree (or trees), with period
-merge points. In this first example, we pull from a tree (pulls,
-"\") periodically, such as what occurs when tracking changes in a
-vendor tree, never pushing changes back up the line:
-
- -------- A --------- B --------- C --------- D -------
- \ \ \
- ----long-term devel branch-----------------
-
-And then a more common case in Linux kernel development, a long term
-branch with periodic merges back into the tree (pushes, "/"):
-
- -------- A --------- B --------- C --------- D -------
- \ \ / \
- ----long-term devel branch-----------------
-
-
-
-
-
-Submitting Changes to Linus
----------------------------
-There's a bit of an art, or style, of submitting changes to Linus.
-Since Linus's tree is now (you might say) fully integrated into the
-distributed BitKeeper system, there are several prerequisites to
-properly submitting a BitKeeper change. All these prereq's are just
-general cleanliness of BK usage, so as people become experts at BK, feel
-free to optimize this process further (assuming Linus agrees, of
-course).
-
-
-
-0) Make sure your tree was originally cloned from the linux-2.5 tree
-created by Linus. If your tree does not have this as its ancestor, it
-is impossible to reliably exchange changesets.
-
-
-
-1) Pay attention to your commit text. The commit message that
-accompanies each changeset you submit will live on forever in history,
-and is used by Linus to accurately summarize the changes in each
-pre-patch. Remember that there is no context, so
- "fix for new scheduler changes"
-would be too vague, but
- "fix mips64 arch for new scheduler switch_to(), TIF_xxx semantics"
-would be much better.
-
-You can and should use the command "bk comment -C<rev>" to update the
-commit text, and improve it after the fact. This is very useful for
-development: poor, quick descriptions during development, which get
-cleaned up using "bk comment" before issuing the "bk push" to submit the
-changes.
-
-
-
-2) Include an Internet-available URL for Linus to pull from, such as
-
- Pull from: http://gkernel.bkbits.net/net-drivers-2.5
-
-
-
-3) Include a summary and "diffstat -p1" of each changeset that will be
-downloaded, when Linus issues a "bk pull". The author auto-generates
-these summaries using "bk changes -L <parent>", to obtain a listing
-of all the pending-to-send changesets, and their commit messages.
-
-It is important to show Linus what he will be downloading when he issues
-a "bk pull", to reduce the time required to sift the changes once they
-are downloaded to Linus's local machine.
-
-IMPORTANT NOTE: One of the features of BK is that your repository does
-not have to be up to date, in order for Linus to receive your changes.
-It is considered a courtesy to keep your repository fairly recent, to
-lessen any potential merge work Linus may need to do.
-
-
-4) Split up your changes. Each maintainer<->Linus situation is likely
-to be slightly different here, so take this just as general advice. The
-author splits up changes according to "themes" when merging with Linus.
-Simultaneous pushes from local development go to special trees which
-exist solely to house changes "queued" for Linus. Example of the trees:
-
- net-drivers-2.5 -- on-going net driver maintenance
- vm-2.5 -- VM-related changes
- fs-2.5 -- filesystem-related changes
-
-Linus then has much more freedom for pulling changes. He could (for
-example) issue a "bk pull" on vm-2.5 and fs-2.5 trees, to merge their
-changes, but hold off net-drivers-2.5 because of a change that needs
-more discussion.
-
-Other maintainers may find that a single linus-pull-from tree is
-adequate for passing BK changesets to him.
-
-
-
-Frequently Answered Questions
------------------------------
-1) How do I change the e-mail address shown in the changelog?
-A. When you run "bk citool" or "bk commit", set environment
- variables BK_USER and BK_HOST to the desired username
- and host/domain name.
-
-
-2) How do I use tags / get a diff between two kernel versions?
-A. Pass the tags Linus uses to 'bk export'.
-
-ChangeSets are in a forward-progressing order, so it's pretty easy
-to get a snapshot starting and ending at any two points in time.
-Linus puts tags on each release and pre-release, so you could use
-these two examples:
-
- bk export -tpatch -hdu -rv2.5.4,v2.5.5 | less
- # creates patch-2.5.5 essentially
- bk export -tpatch -du -rv2.5.5-pre1,v2.5.5 | less
- # changes from pre1 to final
-
-A tag is just an alias for a specific changeset... and since changesets
-are ordered, a tag is thus a marker for a specific point in time (or
-specific state of the tree).
-
-
-3) Is there an easy way to generate One Big Patch versus mainline,
- for my long-lived kernel branch?
-A. Yes. This requires BK 3.x, though.
-
- bk export -tpatch -r`bk repogca bk://linux.bkbits.net/linux-2.5`,+
