Alexander Larsson b67c94a963 devmapper: Move all "raw" libdevmapper wrappers to devmapper.go
This separates out the DeviceSet logic a bit better from the raw
device mapper operations.

devicemapper: Serialize addess to the devicemapper deviceset

This code is not safe to run in multiple threads at the same time,
and neither is libdevmapper.

DeviceMapper: Move deactivate into UnmountDevice

This way the deactivate is atomic wrt othe device mapper operations
and will not fail with EBUSY if someone else starts a devicemapper
operation inbetween unmount and deactivate.

devmapper: Fix loopback mounting regression

Some changes were added to attach_loop_device which added
a perror() in a place that caused it to override errno so that
a later errno != EBUSY failed. This fixes that and cleans up
the error reporting a bit.

devmapper: Build on old kernels without LOOP_CTL_GET_FREE define

# Contributing to Docker
Want to hack on Docker? Awesome! Here are instructions to get you
started. They are probably not perfect, please let us know if anything
feels wrong or incomplete.
## Topics
* [Security Reports](#security-reports)
* [Design and Cleanup Proposals](#design-and-cleanup-proposals)
* [Reporting Issues](#reporting-issues)
* [Build Environment](#build-environment)
* [Contribution Guidelines](#contribution-guidelines)
* [Community Guidelines](#docker-community-guidelines)
## Security Reports
Please **DO NOT** file an issue for security related issues. Please send your
reports to [security@docker.com](mailto:security@docker.com) instead.
## Design and Cleanup Proposals
When considering a design proposal, we are looking for:
* A description of the problem this design proposal solves
* An issue -- not a pull request -- that describes what you will take action on
* Please prefix your issue with `Proposal:` in the title
* Please review [the existing Proposals](https://github.com/dotcloud/docker/issues?direction=asc&labels=Proposal&page=1&sort=created&state=open)
before reporting a new issue. You can always pair with someone if you both
have the same idea.
When considering a cleanup task, we are looking for:
* A description of the refactors made
* Please note any logic changes if necessary
* A pull request with the code
* Please prefix your PR's title with `Cleanup:` so we can quickly address it.
* Your pull request must remain up to date with master, so rebase as necessary.
## Reporting Issues
When reporting [issues](https://github.com/docker/docker/issues) on
GitHub please include your host OS (Ubuntu 12.04, Fedora 19, etc).
Please include:
* The output of `uname -a`.
* The output of `docker version`.
* The output of `docker -D info`.
Please also include the steps required to reproduce the problem if
possible and applicable. This information will help us review and fix
your issue faster.
## Build Environment
For instructions on setting up your development environment, please
see our dedicated [dev environment setup
docs](http://docs.docker.com/contributing/devenvironment/).

Submit unit tests for your changes. Go has a great test framework built in; use
it! Take a look at existing tests for inspiration. Run the full test suite on
your branch before submitting a pull request.
Update the documentation when creating or modifying features. Test
your documentation changes for clarity, concision, and correctness, as
well as a clean documentation build. See `docs/README.md` for more
information on building the docs and how they get released.
Make sure you include relevant updates or additions to documentation when
creating or modifying features.
Write clean code. Universally formatted code promotes ease of writing, reading,
and maintenance. Always run `gofmt -s -w file.go` on each changed file before
committing your changes. Most editors have plug-ins that do this automatically.
and maintenance. Always run `go fmt` before committing your changes. Most
editors have plugins that do this automatically, and there's also a git
pre-commit hook:
```
curl -o .git/hooks/pre-commit https://raw.github.com/edsrzf/gofmt-git-hook/master/fmt-check && chmod +x .git/hooks/pre-commit
```
Pull requests descriptions should be as clear as possible and include a
reference to all the issues that they address.
Commit messages must start with a capitalized and short summary (max. 50
chars) written in the imperative, followed by an optional, more detailed
explanatory text which is separated from the summary by an empty line.
Code review comments may be added to your pull request. Discuss, then make the
suggested modifications and push additional commits to your feature branch. Be
sure to post a comment after pushing. The new commits will show up in the pull
request automatically, but the reviewers will not be notified unless you
comment.
Pull requests must be cleanly rebased ontop of master without multiple branches
mixed into the PR.
**Git tip**: If your PR no longer merges cleanly, use `rebase master` in your
feature branch to update your pull request rather than `merge master`.
Before the pull request is merged, make sure that you squash your commits into
logical units of work using `git rebase -i` and `git push -f`. After every
commit the test suite should be passing. Include documentation changes in the
same commit so that a revert would remove all traces of the feature or fix.
Commits that fix or close an issue should include a reference like
`Closes #XXXX` or `Fixes #XXXX`, which will automatically close the
issue when merged.
Commits that fix or close an issue should include a reference like `Closes #XXX`
or `Fixes #XXX`, which will automatically close the issue when merged.
Please do not add yourself to the `AUTHORS` file, as it is regenerated
regularly from the Git history.
Add your name to the AUTHORS file, but make sure the list is sorted and your
name and email address match your git configuration. The AUTHORS file is
regenerated occasionally from the git commit history, so a mismatch may result
in your changes being overwritten.
### Merge approval
Docker maintainers use LGTM (Looks Good To Me) in comments on the code review
to indicate acceptance.
A change requires LGTMs from an absolute majority of the maintainers of each
component affected. For example, if a change affects `docs/` and `registry/`, it
needs an absolute majority from the maintainers of `docs/` AND, separately, an
absolute majority of the maintainers of `registry/`.
For more details see [MAINTAINERS.md](hack/MAINTAINERS.md)
### Sign your work
The sign-off is a simple line at the end of the explanation for the
patch, which certifies that you wrote it or otherwise have the right to
pass it on as an open-source patch. The rules are pretty simple: if you
can certify the below (from

person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
```
Then you just add a line to every git commit message:
Signed-off-by: Joe Smith <joe.smith@email.com>
Using your real name (sorry, no pseudonyms or anonymous contributions.)
If you set your `user.name` and `user.email` git configs, you can sign your
commit automatically with `git commit -s`.
Note that the old-style `Docker-DCO-1.1-Signed-off-by: ...` format is still
accepted, so there is no need to update outstanding pull requests to the new
format right away, but please do adjust your processes for future contributions.
#### Small patch exception
There are several exceptions to the signing requirement. Currently these are:
* Your patch fixes spelling or grammar errors.
* Your patch is a single line change to documentation contained in the
`docs` directory.
* Your patch fixes Markdown formatting or syntax errors in the
documentation contained in the `docs` directory.
If you have any questions, please refer to the FAQ in the [docs](http://docs.docker.com)
### How can I become a maintainer?
* Step 1: Learn the component inside out
* Step 2: Make yourself useful by contributing code, bug fixes, support etc.
* Step 3: Volunteer on the IRC channel (#docker at Freenode)
* Step 4: Propose yourself at a scheduled docker meeting in #docker-dev
* Step 1: learn the component inside out
* Step 2: make yourself useful by contributing code, bugfixes, support etc.
* Step 3: volunteer on the irc channel (#docker@freenode)
Don't forget: being a maintainer is a time investment. Make sure you
will have time to make yourself available. You don't have to be a
maintainer to make a difference on the project!
### IRC Meetings
There are two monthly meetings taking place on #docker-dev IRC to accomodate all timezones.
Anybody can ask for a topic to be discussed prior to the meeting.
If you feel the conversation is going off-topic, feel free to point it out.
For the exact dates and times, have a look at [the irc-minutes repo](https://github.com/docker/irc-minutes).
They also contain all the notes from previous meetings.
## Docker Community Guidelines
We want to keep the Docker community awesome, growing and collaborative. We
need your help to keep it that way. To help with this we've come up with some
general guidelines for the community as a whole:
* Be nice: Be courteous, respectful and polite to fellow community members: no
regional, racial, gender, or other abuse will be tolerated. We like nice people
way better than mean ones!
* Encourage diversity and participation: Make everyone in our community
feel welcome, regardless of their background and the extent of their
contributions, and do everything possible to encourage participation in
our community.
* Keep it legal: Basically, don't get us in trouble. Share only content that
you own, do not share private or sensitive information, and don't break the
law.
* Stay on topic: Make sure that you are posting to the correct channel
and avoid off-topic discussions. Remember when you update an issue or
respond to an email you are potentially sending to a large number of
people. Please consider this before you update. Also remember that
nobody likes spam.
### Guideline Violations — 3 Strikes Method
The point of this section is not to find opportunities to punish people, but we
do need a fair way to deal with people who are making our community suck.
1. First occurrence: We'll give you a friendly, but public reminder that the
behavior is inappropriate according to our guidelines.
2. Second occurrence: We will send you a private message with a warning that
any additional violations will result in removal from the community.
3. Third occurrence: Depending on the violation, we may need to delete or ban
your account.
**Notes:**
* Obvious spammers are banned on first occurrence. If we don't do this, we'll
have spam all over the place.
* Violations are forgiven after 6 months of good behavior, and we won't
hold a grudge.
* People who commit minor infractions will get some education,
rather than hammering them in the 3 strikes process.
* The rules apply equally to everyone in the community, no matter how
much you've contributed.
* Extreme violations of a threatening, abusive, destructive or illegal nature
will be addressed immediately and are not subject to 3 strikes or
forgiveness.
* Contact james@docker.com to report abuse or appeal violations. In the case of
appeals, we know that mistakes happen, and we'll work with you to come up with
a fair solution if there has been a misunderstanding.
Don't forget: being a maintainer is a time investment. Make sure you will have time to make yourself available.
You don't have to be a maintainer to make a difference on the project!

## FIXME
This file is a loose collection of things to improve in the codebase, for the internal
use of the maintainers.
They are not big enough to be in the roadmap, not user-facing enough to be github issues,
and not important enough to be discussed in the mailing list.
They are just like FIXME comments in the source code, except we're not sure where in the source
to put them - so we put them here :)
* Merge Runtime, Server and Builder into Runtime
* Run linter on codebase
* Unify build commands and regular commands
* Move source code into src/ subdir for clarity
* Clean up the Makefile, it's a mess
* docker build: on non-existent local path for ADD, don't show full absolute path on the host
* mount into /dockerinit rather than /sbin/init
* docker tag foo REPO:TAG
* use size header for progress bar in pull
* Clean up context upload in build!!!
* Parallel pull
* Ensure /proc/sys/net/ipv4/ip_forward is 1
* Force DNS to public!
* Always generate a resolv.conf per container, to avoid changing resolv.conf under thne container's feet
* Save metadata with import/export
* Upgrade dockerd without stopping containers
* bring back git revision info, looks like it was lost
* Simple command to remove all untagged images
* Simple command to clean up containers for disk space
* Caching after an ADD
* entry point config
* bring back git revision info, looks like it was lost
* Clean up the ProgressReader api, it's a PITA to use
* Use netlink instead of iproute2/iptables (#925)

What does that mean?

For more information, please see http://www.bis.doc.gov
Like all software products that utilize cryptography, the export and
use of Docker is subject to the U.S. Commerce Department's Export
Administration Regulations (EAR) because it uses or contains
cryptography (see
http://www.bis.doc.gov/index.php/policy-guidance/encryption). Certain
free and open source software projects have a lightweight set of
requirements, which can generally be met by providing email notice to
the appropriate U.S. government agencies that their source code is
available on a publicly available repository and making the
appropriate statements in the README.
See also http://www.apache.org/dev/crypto.html and/or seek legal counsel.
The restrictions of the EAR apply to certain denied locations
(currently Iran, Sudan, Syria, North Korea, or Cuba) and those
individuals on the Denied Persons List, which is available here:
http://www.bis.doc.gov/index.php/policy-guidance/lists-of-parties-of-concern/denied-persons-list.
If you are incorporating Docker into a new open source project, the
EAR restrictions apply to your incorporation of Docker into your
project in the same manner as other cryptography-enabled projects,
such as OpenSSL, almost all Linux distributions, etc.

# Dockerfile.tmLanguage
Pretty basic Dockerfile.tmLanguage for Sublime Text syntax highlighting.
PR's with syntax updates, suggestions etc. are all very much appreciated!
I'll get to making this installable via Package Control soon!
enjoy.

# docker-brew
docker-brew is a command-line tool used to build the docker standard library.
## Install instructions
1. Install python if it isn't already available on your OS of choice
1. Install the easy_install tool (`sudo apt-get install python-setuptools`
for Debian)
1. Install the python package manager, `pip` (`easy_install pip`)
1. Run the following command: `sudo pip install -r requirements.txt`
1. You should now be able to use the `docker-brew` script as such.
## Basics
./docker-brew -h
Display usage and help.
./docker-brew
Default build from the default repo/branch. Images will be created under the
`library/` namespace. Does not perform a remote push.
./docker-brew -n mycorp.com -b stable --push git://github.com/mycorp/docker
Will fetch the library definition files in the `stable` branch of the
`git://github.com/mycorp/docker` repository and create images under the
`mycorp.com` namespace (e.g. `mycorp.com/ubuntu`). Created images will then
be pushed to the official docker repository (pending: support for private
repositories)
## Library definition files
The library definition files are plain text files found in the `library/`
subfolder of the docker repository.
### File names
The name of a definition file will determine the name of the image(s) it
creates. For example, the `library/ubuntu` file will create images in the
`<namespace>/ubuntu` repository. If multiple instructions are present in
a single file, all images are expected to be created under a different tag.
### Instruction format
Each line represents a build instruction.
There are different formats that `docker-brew` is able to parse.
<git-url>
git://github.com/dotcloud/hipache
https://github.com/dotcloud/docker.git
The simplest format. `docker-brew` will fetch data from the provided git
repository from the `HEAD`of its `master` branch. Generated image will be
tagged as `latest`. Use of this format is discouraged because there is no
way to ensure stability.
<docker-tag> <git-url>
bleeding-edge git://github.com/dotcloud/docker
unstable https://github.com/dotcloud/docker-redis.git
A more advanced format. `docker-brew` will fetch data from the provided git
repository from the `HEAD`of its `master` branch. Generated image will be
tagged as `<docker-tag>`. Recommended if we always want to provide a snapshot
of the latest development. Again, no way to ensure stability.
<docker-tag> <git-url> T:<git-tag>
2.4.0 git://github.com/dotcloud/docker-redis T:2.4.0
<docker-tag> <git-url> B:<git-branch>
zfs git://github.com/dotcloud/docker B:zfs-support
<docker-tag> <git-url> C:<git-commit-id>
2.2.0 https://github.com/dotcloud/docker-redis.git C:a4bf8923ee4ec566d3ddc212
The most complete format. `docker-brew` will fetch data from the provided git
repository from the provided reference (if it's a branch, brew will fetch its
`HEAD`). Generated image will be tagged as `<docker-tag>`. Recommended whenever
possible.

# bash completion file for core docker commands
#
# This script provides supports completion of:
# - commands and their options
# - container ids and names
# - image repos and tags
# - filepaths
#
# To enable the completions either:
# - place this file in /etc/bash_completion.d
# or
# - copy this file and add the line below to your .bashrc after
# bash completion features are loaded
# . docker.bash
#
# Note:
# Currently, the completions will not work if the docker daemon is not
# bound to the default communication port/socket
# If the docker daemon is using a unix socket for communication your user
# must have access to the socket for the completions to function correctly

# # Build iceweasel image
# docker build -t iceweasel .
