From 7829f8b05d257448fd38b54fce71dafc265ec80a Mon Sep 17 00:00:00 2001 From: Andy Goldstein Date: Fri, 22 Jan 2016 06:35:55 -0500 Subject: [PATCH 001/361] Move resize after attaching Resize by +1 when attaching to force redrawing. Start monitoring window size after the attach begins instead of before. This way, you see the output from the container without having to manually resize or hit enter. This makes attach consistent with run and exec.

This allows for a more descriptive error message to be seen by the end user. - Change some logrus.Debugf calls that display errors to logrus.Errorf. Add log lines in the push/pull fallback cases to make sure the errors leading to the fallback are shown. - Move error-related types and functions which are only used by the distribution package out of the registry package.

It is a virtual _Ethernet bridge_ that automatically forwards packets between any other network interfaces that are attached to it. This lets containers communicate both with the host machine and with each other.

You might adjust the instructions of the previous section to go something like this: - -``` -# Start up two containers in two terminal windows - -$ docker run -i -t --rm --net=none base /bin/bash -root@1f1f4c1f931a:/# - -$ docker run -i -t --rm --net=none base /bin/bash -root@12e343489d2f:/# - -# Learn the container process IDs -# and create their namespace entries - -$ docker inspect -f '{{.State.Pid}}' 1f1f4c1f931a -2989 -$ docker inspect -f '{{.State.Pid}}' 12e343489d2f -3004 -$ sudo mkdir -p /var/run/netns -$ sudo ln -s /proc/2989/ns/net /var/run/netns/2989 -$ sudo ln -s /proc/3004/ns/net /var/run/netns/3004 - -# Create the "peer" interfaces and hand them out - -$ sudo ip link add A type veth peer name B - -$ sudo ip link set A netns 2989 -$ sudo ip netns exec 2989 ip addr add 10.1.1.1/32 dev A -$ sudo ip netns exec 2989 ip link set A up -$ sudo ip netns exec 2989 ip route add 10.1.1.2/32 dev A - -$ sudo ip link set B netns 3004 -$ sudo ip netns exec 3004 ip addr add 10.1.1.2/32 dev B -$ sudo ip netns exec 3004 ip link set B up -$ sudo ip netns exec 3004 ip route add 10.1.1.1/32 dev B -``` - -The two containers should now be able to ping each other and make connections successfully. Point-to-point links like this do not depend on a subnet nor a netmask, but on the bare assertion made by `ip route` that some other single IP address is connected to a particular network interface. - -Note that point-to-point links can be safely combined with other kinds of network connectivity -- there is no need to start the containers with `--net=none` if you want point-to-point links to be an addition to the container's normal networking instead of a replacement. - -A final permutation of this pattern is to create the point-to-point link between the Docker host and one container, which would allow the host to communicate with that one container on some single IP address and thus communicate "out-of-band" of the bridge that connects the other, more usual containers. But unless you have very specific networking needs that drive you to such a solution, it is probably far preferable to use `--icc=false` to lock down inter-container communication, as we explored earlier.

An old client talking to a new server isn't an error condition, nor is it something to even worry about - its a normal part of life. Flooding my screen (and logs) with a warning that isn't something I (as an admin) need to be concerned about is silly and a distraction when I need to look for real issues. If anything this should be printed on the cli not the daemon since its the cli that needs to be concerned, not the daemon. However, since when you debug an issue it might be interesting to know the client is old I decided to pull back a little and just change it from a Warning to a Debug logrus call instead.

It doesn't make sense to try plaintext if a HTTP request went through while using TLS. This commit changes the logic to keep track of host/port combinations where a TLS attempt managed to do at least one HTTP request (whether the response code indicated success or not). If the host/port responded to a HTTP using TLS, we won't try to make plaintext HTTP requests to it. This will result in better error messages, which sometimes ended up showing the result of the plaintext attempt, like this: Error response from daemon: Get http://myregistrydomain.com:5000/v2/: malformed HTTP response "\x15\x03\x01\x00\x02\x02" Signed-off-by: Aaron Lehmann Upstream-commit: 5e8af46fda3f4e17e06726237fc6b9ab6957e3ea Component: engine --- components/engine/distribution/errors.go | 4 +++ components/engine/distribution/pull.go | 23 +++++++++++++++++ components/engine/distribution/pull_v2.go | 20 ++++++++++++--- components/engine/distribution/push.go | 22 ++++++++++++++++ components/engine/distribution/push_v2.go | 8 ++++-- components/engine/distribution/registry.go | 29 ++++++++++++++++++---- 6 files changed, 95 insertions(+), 11 deletions(-) diff --git a/components/engine/distribution/errors.go b/components/engine/distribution/errors.go index 9f9dcf6978..1cb34fdd51 100644 --- a/components/engine/distribution/errors.go +++ b/components/engine/distribution/errors.go @@ -31,6 +31,10 @@ type fallbackError struct { // supports the v2 protocol.

But at the time that the inotify event is received, the json line might not fully saved to disk. If the json decoder tries to decode in such case, an io.UnexpectedEOF will be trigged. We used to retry for several times to mitigate the io.UnexpectedEOF error. But there are still flaky tests caused by the partial log entries. The daemon knows exactly when there are new log entries emitted. We can use the pubsub package to notify all the log readers instead of inotify.

This change implements communication with an external credentials store, ala git-credential-helper. The client falls back the plain text store, what we're currently using, if there is no remote store configured. It shells out to helper program when a credential store is configured. Those programs can be implemented with any language as long as they follow the convention to pass arguments and information. There is an implementation for the OS X keychain in https://github.com/calavera/docker-credential-helpers. That package also provides basic structure to create other helpers.

Also splits some of the stats helpers to a separate file from the stats CLI which is already quite long.

This PR removed the logic that shares digests between different push sessions. This overlooked the case where one session was waiting for another session to upload a layer. This commit adds back the ability to propagate this digest information, using the distribution.Descriptor type because this is what is received from stats and uploads, and also what is ultimately needed for building the manifest. Surprisingly, there was no test covering this case. This commit adds one. It fails without the fix. See recent comments on #9132.

The test still appears to be flaky. There are two potential problems. The initial pull was not protected against pulling from v1, so it could be giving us a different hello-world image to compare against.

This PR fix the DockerSuite.TestBuildHistory test in #19425. It changes the base image from busybox into 'minimalBaseImage()' and changes the RUN in Dockerfile into LABEL, which greatly reduces the executation time. Since the test (DockerSuite.TestBuildHistory) is really about testing docker history, not about RUN in Dockerfile, the purpose of the test is not altered.

This caused problems with tar-split and tarsum and led to performance problems in implementing methods such as DiffPath. It also was just an unnecessary differentiation point between Windows and Linux. With this change, Windows layer diffs look much more like their Linux counterparts. They use AUFS-style whiteout files for files that have been removed, and they encode all metadata directly in the tar file. This change only affects Windows post-TP4, since changes to the Windows container storage APIs were necessary to make this possible.

This PR fix the DockerHubPullSuite.TestPullNonExistingImage test in #19425. The majority of the execution time in this test is from multiple executions of 'docker pull', each of which takes more than one second even though it tries to pull a non-existing image. Without changing the behavior of the 'docker pull' itself, this fix tries to execute the 'docker pull' command in parallel in order to speed up the execution of the overall test. Since each 'docker pull' is independent, executions in parallel should not alter the purpose of the test.

This PR fix the DockerSuite.TestBuildDockerignoringWildDirs test in #19425. Instead of having multiple RUN instructions in Dockerfile for every single directory tested, this PR tries to collapse multiple RUN instructions into one RUN instruction in Dockerfile. When a docker image is built, each RUN instruction in Dockerfile will generate one layer in history. It takes considerable amount of time to build many layers if there are many RUN instructions within the Dockerfile. Collapsing into one RUN instruction not only speeds up the execution significantly, it also conforms to the general guideline of the Dockerfile reference. Since the test (DockerSuite.TestBuildDockerignoringWildDirs) is really about testing the docker build with ignoring wild directories, the purpose of the test is not altered with this PR fix.

This might work on arm64 platforms that support 32-bit mode. However not all arm64 platforms support 32-bit mode. 32-bit mode is optional for ARMv8. So use gccgo as bootstrap.

This fix tries to improve the time to run TestRunUnshareProc in #19425. In this fix goroutines are used to run test cases in parallel to prevent the test from taking a long time to run. As the majority of the execution time in the tests is from multiple executions of 'docker run' and each of which takes several seconds, parallel executions improve the test time. Since each 'docker run' is independent, the purpose of the test is not altered in this fix.

-## Issues - -* Request features and report bugs using the [GitHub Issue Tracker](https://github.com/go-fsnotify/fsnotify/issues). -* Please indicate the platform you are using fsnotify on. -* A code example to reproduce the problem is appreciated. - -## Pull Requests - -### Contributor License Agreement - -fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/go-fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/go-fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual). - -Please indicate that you have signed the CLA in your pull request. - -### How fsnotify is Developed - -* Development is done on feature branches. -* Tests are run on BSD, Linux, OS X and Windows. -* Pull requests are reviewed and [applied to master][am] using [hub][]. - * Maintainers may modify or squash commits rather than asking contributors to. -* To issue a new release, the maintainers will: - * Update the CHANGELOG - * Tag a version, which will become available through gopkg.in. - -### How to Fork - -For smooth sailing, always use the original import path. Installing with `go get` makes this easy. - -1. Install from GitHub (`go get -u github.com/go-fsnotify/fsnotify`) -2. Create your feature branch (`git checkout -b my-new-feature`) -3. Ensure everything works and the tests pass (see below) -4. Commit your changes (`git commit -am 'Add some feature'`) - -Contribute upstream: - -1. Fork fsnotify on GitHub -2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`) -3. Push to the branch (`git push fork my-new-feature`) -4. Create a new Pull Request on GitHub - -This workflow is [thoroughly explained by Katrina Owen](https://blog.splice.com/contributing-open-source-git-repositories-go/). - -### Testing - -fsnotify uses build tags to compile different code on Linux, BSD, OS X, and Windows. - -Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on. - -To aid in cross-platform testing there is a Vagrantfile for Linux and BSD. - -* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/) -* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder. -* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password) -* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd go-fsnotify/fsnotify; go test'`. -* When you're done, you will want to halt or destroy the Vagrant boxes. - -Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory. - -Right now there is no equivalent solution for Windows and OS X, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads). - -### Maintainers - -Help maintaining fsnotify is welcome. To be a maintainer: - -* Submit a pull request and sign the CLA as above. -* You must be able to run the test suite on Mac, Windows, Linux and BSD. - -To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][]. - -All code changes should be internal pull requests. - -Releases are tagged using [Semantic Versioning](http://semver.org/). - -[hub]: https://github.com/github/hub -[am]: http://blog.spreedly.com/2014/06/24/merge-pull-request-considered-harmful/#.VGa5yZPF_Zs diff --git a/components/engine/vendor/src/gopkg.in/fsnotify.v1/LICENSE b/components/engine/vendor/src/gopkg.in/fsnotify.v1/LICENSE deleted file mode 100644 index f21e540800..0000000000 --- a/components/engine/vendor/src/gopkg.in/fsnotify.v1/LICENSE +++ /dev/null @@ -1,28 +0,0 @@ -Copyright (c) 2012 The Go Authors.

If we continued to store the URL unparsed, it would require redundant parsing whenver we want to extract information from it. Also, parsing the URL earlier should give improve validation.

Features and refactoring -## 1.1 Security +## 1.1 Runtime improvements -Security is a top objective for the Docker Engine. The most notable items we intend to provide in -the near future are: +We recently introduced [`runC`](https://runc.io) as a standalone low-level tool for container +execution. The initial goal was to integrate runC as a replacement in the Engine for the traditional +default libcontainer `execdriver`, but the Engine internals were not ready for this. -- Trusted distribution of images: the effort is driven by the [distribution](https://github.com/docker/distribution) -group but will have significant impact on the Engine -- [User namespaces](https://github.com/docker/docker/pull/12648) -- [Seccomp support](https://github.com/docker/libcontainer/pull/613) +As runC continued evolving, and the OCI specification along with it, we created +[`containerd`](https://containerd.tools/), a daemon to control and monitor multiple `runC`. This is +the new target for Engine integration, as it can entirely replace the whole `execdriver` +architecture, and container monitoring along with it. -## 1.2 Plumbing project +Docker Engine will rely on a long-running `containerd` companion daemon for all container execution +related operations. This could open the door in the future for Engine restarts without interrupting +running containers. -We define a plumbing tool as a standalone piece of software usable and meaningful on its own. In -the current state of the Docker Engine, most subsystems provide independent functionalities (such -the builder, pushing and pulling images, running applications in a containerized environment, etc) -but all are coupled in a single binary. We want to offer the users to flexibility to use only the -pieces they need, and we will also gain in maintainability by splitting the project among multiple -repositories. +## 1.2 Plugins improvements -As it currently stands, the rough design outlines is to have: -- Low level plumbing tools, each dealing with one responsibility (e.g., [runC](https://runc.io)) -- Docker subsystems services, each exposing an elementary concept over an API, and relying on one or -multiple lower level plumbing tools for their implementation (e.g., network management) -- Docker Engine to expose higher level actions (e.g., create a container with volume `V` and network -`N`), while still providing pass-through access to the individual subsystems. +Docker Engine 1.7.0 introduced plugin support, initially for the use cases of volumes and networks +extensions. The plugin infrastructure was kept minimal as we were collecting use cases and real +world feedback before optimizing for any particular workflow. -The architectural details are still being worked on, but one thing we know for sure is that we need -to technically decouple the pieces. +In the future, we'd like plugins to become first class citizens, and encourage an ecosystem of +plugins. This implies in particular making it trivially easy to distribute plugins as containers +through any Registry instance, as well as solving the commonly heard pain points of plugins needing +to be treated as somewhat special (being active at all time, started before any other user +containers, and not as easily dismissed). -### 1.2.1 Runtime +## 1.3 Internal decoupling -A Runtime tool already exists today in the form of [runC](https://github.com/opencontainers/runc). -We intend to modify the Engine to directly call out to a binary implementing the Open Containers -Specification such as runC rather than relying on libcontainer to set the container runtime up. +A lot of work has been done in trying to decouple the Docker Engine's internals. In particular, the +API implementation has been refactored and ongoing work is happening to move the code to a separate +repository ([`docker/engine-api`](https://github.com/docker/engine-api)), and the Builder side of +the daemon is now [fully independent](https://github.com/docker/docker/tree/master/builder) while +still residing in the same repository. -This plan will deprecate the existing [`execdriver`](https://github.com/docker/docker/tree/master/daemon/execdriver) -as different runtime backends will be implemented as separated binaries instead of being compiled -into the Engine. +We are exploring ways to go further with that decoupling, capitalizing on the work introduced by the +runtime renovation and plugins improvement efforts. Indeed, the combination of `containerd` support +with the concept of "special" containers opens the door for bootstrapping more Engine internals +using the same facilities. -### 1.2.2 Builder +## 1.4 Cluster capable Engine -The Builder (i.e., the ability to build an image from a Dockerfile) is already nicely decoupled, -but would benefit from being entirely separated from the Engine, and rely on the standard Engine -API for its operations. +The community has been pushing for a more cluster capable Docker Engine, and a huge effort was spent +adding features such as multihost networking, and node discovery down at the Engine level. Yet, the +Engine is currently incapable of taking scheduling decisions alone, and continues relying on Swarm +for that. -### 1.2.3 Distribution - -Distribution already has a [dedicated repository](https://github.com/docker/distribution) which -holds the implementation for Registry v2 and client libraries. We could imagine going further by -having the Engine call out to a binary providing image distribution related functionalities. - -There are two short term goals related to image distribution. The first is stabilize and simplify -the push/pull code. Following that is the conversion to the more secure Registry V2 protocol. - -### 1.2.4 Networking - -Most of networking related code was already decoupled today in [libnetwork](https://github.com/docker/libnetwork). -As with other ingredients, we might want to take it a step further and make it a meaningful utility -that the Engine would call out to instead of a library. - -## 1.3 Plugins - -An initiative around plugins started with Docker 1.7.0, with the goal of allowing for out of -process extensibility of some Docker functionalities, starting with volumes and networking. The -approach is to provide specific extension points rather than generic hooking facilities. We also -deliberately keep the extensions API the simplest possible, expanding as we discover valid use -cases that cannot be implemented. - -At the time of writing: - -- Plugin support is merged as an experimental feature: real world use cases and user feedback will -help us refine the UX to make the feature more user friendly. -- There are no immediate plans to expand on the number of pluggable subsystems. -- Golang 1.5 might add language support for [plugins](https://docs.google.com/document/d/1nr-TQHw_er6GOQRsF6T43GGhFDelrAP0NqSS_00RgZQ) -which we consider supporting as an alternative to JSON/HTTP. - -## 1.4 Volume management - -Volumes are not a first class citizen in the Engine today: we would like better volume management, -similar to the way network are managed in the new [CNM](https://github.com/docker/docker/issues/9983). - -## 1.5 Better API implementation - -The current Engine API is insufficiently typed, versioned, and ultimately hard to maintain. We -also suffer from the lack of a common implementation with [Swarm](https://github.com/docker/swarm). - -## 1.6 Checkpoint/restore - -Support for checkpoint/restore was [merged](https://github.com/docker/libcontainer/pull/479) in -[libcontainer](https://github.com/docker/libcontainer) and made available through [runC](https://runc.io): -we intend to take advantage of it in the Engine. +We plan to complete this effort and make Engine fully cluster capable. Multiple instances of the +Docker Engine being already capable of discovering each other and establish overlay networking for +their container to communicate, the next step is for a given Engine to gain ability to dispatch work +to another node in the cluster.

When the value for a configuration option in the file is `false`, and the default value for a flag is `true`, we should not take the value from the later as final value for the option, because the user explicitly set `false`. This change overrides the default value in the flagSet with the value in the configuration file so we get the correct result when we merge the two configurations together.

Installing with `go get` makes this easy. + +1. Install from GitHub (`go get -u github.com/go-fsnotify/fsnotify`) +2. Create your feature branch (`git checkout -b my-new-feature`) +3. Ensure everything works and the tests pass (see below) +4. Commit your changes (`git commit -am 'Add some feature'`) + +Contribute upstream: + +1. Fork fsnotify on GitHub +2.

Create a new Pull Request on GitHub + +This workflow is [thoroughly explained by Katrina Owen](https://blog.splice.com/contributing-open-source-git-repositories-go/). + +### Testing + +fsnotify uses build tags to compile different code on Linux, BSD, OS X, and Windows. + +Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on. + +To aid in cross-platform testing there is a Vagrantfile for Linux and BSD. + +* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/) +* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder. +* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password) +* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd go-fsnotify/fsnotify; go test'`. +* When you're done, you will want to halt or destroy the Vagrant boxes. + +Notice: fsnotify file system events won't trigger in shared folders.

This will add a warning if it is actually disabled and notes what has to be added to the grub/boot command line to enable it.

It is used by [gRPC](https://github.com/grpc). The error model is designed to be: - Simple to use and understand for most users - Flexible enough to meet unexpected needs # Overview The `Status` message contains three pieces of data: error code, error message, and error details. The error code should be an enum value of google.rpc.Code, but it may accept additional error codes if needed. The error message should be a developer-facing English message that helps developers *understand* and *resolve* the error. If a localized user-facing error message is needed, put the localized message in the error details or localize it in the client. The optional error details may contain arbitrary information about the error. There is a predefined set of error detail types in the package `google.rpc` which can be used for common error conditions. # Language mapping The `Status` message is the logical representation of the error model, but it is not necessarily the actual wire format. When the `Status` message is exposed in different client libraries and different wire protocols, it can be mapped differently. For example, it will likely be mapped to some exceptions in Java, but more likely mapped to some error codes in C. # Other uses The error model and the `Status` message can be used in a variety of environments, either with or without APIs, to provide a consistent developer experience across different environments. Example uses of this error model include: - Partial errors. If a service needs to return partial errors to the client, it may embed the `Status` in the normal response to indicate the partial errors. - Workflow errors. A typical workflow has multiple steps. Each step may have a `Status` message for error reporting purpose. - Batch operations. If a client uses batch request and batch response, the `Status` message should be used directly inside batch response, one for each error sub-response. - Asynchronous operations. If an API call embeds asynchronous operation results in its response, the status of those operations should be represented directly using the `Status` message. - Logging. If some API errors are stored in logs, the message `Status` could be used directly after any stripping needed for security/privacy reasons.", + "properties": { + "code": { + "type": "integer", + "description": "The status code, which should be an enum value of google.rpc.Code.", + "format": "int32" + }, + "message": { + "type": "string", + "description": "A developer-facing error message, which should be in English.

It is used by [gRPC](https://github.com/grpc). The +// error model is designed to be: - Simple to use and understand for +// most users - Flexible enough to meet unexpected needs # Overview The +// `Status` message contains three pieces of data: error code, error +// message, and error details. The error code should be an enum value of +// google.rpc.Code, but it may accept additional error codes if needed. +// The error message should be a developer-facing English message that +// helps developers *understand* and *resolve* the error. If a localized +// user-facing error message is needed, put the localized message in the +// error details or localize it in the client. The optional error +// details may contain arbitrary information about the error. There is a +// predefined set of error detail types in the package `google.rpc` +// which can be used for common error conditions. # Language mapping The +// `Status` message is the logical representation of the error model, +// but it is not necessarily the actual wire format. When the `Status` +// message is exposed in different client libraries and different wire +// protocols, it can be mapped differently. For example, it will likely +// be mapped to some exceptions in Java, but more likely mapped to some +// error codes in C. # Other uses The error model and the `Status` +// message can be used in a variety of environments, either with or +// without APIs, to provide a consistent developer experience across +// different environments. Example uses of this error model include: - +// Partial errors. If a service needs to return partial errors to the +// client, it may embed the `Status` in the normal response to indicate +// the partial errors. - Workflow errors. A typical workflow has +// multiple steps. Each step may have a `Status` message for error +// reporting purpose. - Batch operations. If a client uses batch request +// and batch response, the `Status` message should be used directly +// inside batch response, one for each error sub-response. - +// Asynchronous operations. If an API call embeds asynchronous operation +// results in its response, the status of those operations should be +// represented directly using the `Status` message. - Logging. If some +// API errors are stored in logs, the message `Status` could be used +// directly after any stripping needed for security/privacy reasons. +type Status struct { + // Code: The status code, which should be an enum value of + // google.rpc.Code. + Code int64 `json:"code,omitempty"` + + // Details: A list of messages that carry the error details.

But this is not true, for example, I start a daemon with -D to enable the debugging, and after a while, I want reconfigure the 'label', so I add a file '/etc/docker/daemon.json' with content '"labels":["test"]' and send SIGHUP to daemon to reconfigure the daemon, it work, but the debugging of the daemon is also diabled. I don't think this is a expeted behaviour. This patch also have some minor refactor of reconfiguration of cluster-advertiser. Enable user to reconfigure cluster-advertiser without cluster-store in config file since cluster-store could also be already set in flag, and we only want to reconfigure the cluster-advertiser.

Moving all strings to the errors package wasn't a good idea after all. Our custom implementation of Go errors predates everything that's nice and good about working with errors in Go. Take as an example what we have to do to get an error message: ```go func GetErrorMessage(err error) string { switch err.(type) { case errcode.Error: e, _ := err.(errcode.Error) return e.Message case errcode.ErrorCode: ec, _ := err.(errcode.ErrorCode) return ec.Message() default: return err.Error() } } ``` This goes against every good practice for Go development. The language already provides a simple, intuitive and standard way to get error messages, that is calling the `Error()` method from an error. Reinventing the error interface is a mistake. Our custom implementation also makes very hard to reason about errors, another nice thing about Go. I found several (>10) error declarations that we don't use anywhere. This is a clear sign about how little we know about the errors we return. I also found several error usages where the number of arguments was different than the parameters declared in the error, another clear example of how difficult is to reason about errors. Moreover, our custom implementation didn't really make easier for people to return custom HTTP status code depending on the errors. Again, it's hard to reason about when to set custom codes and how. Take an example what we have to do to extract the message and status code from an error before returning a response from the API: ```go switch err.(type) { case errcode.ErrorCode: daError, _ := err.(errcode.ErrorCode) statusCode = daError.Descriptor().HTTPStatusCode errMsg = daError.Message() case errcode.Error: // For reference, if you're looking for a particular error // then you can do something like : // import ( derr "github.com/docker/docker/errors" ) // if daError.ErrorCode() == derr.ErrorCodeNoSuchContainer { ... } daError, _ := err.(errcode.Error) statusCode = daError.ErrorCode().Descriptor().HTTPStatusCode errMsg = daError.Message default: // This part of will be removed once we've // converted everything over to use the errcode package // FIXME: this is brittle and should not be necessary. // If we need to differentiate between different possible error types, // we should create appropriate error types with clearly defined meaning errStr := strings.ToLower(err.Error()) for keyword, status := range map[string]int{ "not found": http.StatusNotFound, "no such": http.StatusNotFound, "bad parameter": http.StatusBadRequest, "conflict": http.StatusConflict, "impossible": http.StatusNotAcceptable, "wrong login/password": http.StatusUnauthorized, "hasn't been activated": http.StatusForbidden, } { if strings.Contains(errStr, keyword) { statusCode = status break } } } ``` You can notice two things in that code: 1. We have to explain how errors work, because our implementation goes against how easy to use Go errors are. 2. At no moment we arrived to remove that `switch` statement that was the original reason to use our custom implementation. This change removes all our status errors from the errors package and puts them back in their specific contexts. IT puts the messages back with their contexts. That way, we know right away when errors used and how to generate their messages. It uses custom interfaces to reason about errors. Errors that need to response with a custom status code MUST implementent this simple interface: ```go type errorWithStatus interface { HTTPErrorStatusCode() int } ``` This interface is very straightforward to implement. It also preserves Go errors real behavior, getting the message is as simple as using the `Error()` method. I included helper functions to generate errors that use custom status code in `errors/errors.go`. By doing this, we remove the hard dependency we have eeverywhere to our custom errors package. Yes, you can use it as a helper to generate error, but it's still very easy to generate errors without it.

Stop using global variables as prefixes to inject the writer header. That can cause issues when two writers set the length of the buffer in the same header concurrently. Stop Writing to the internal buffer twice for each write. This could mess up with the ordering information is written.
