The need has been spotted in issue https://github.com/hashicorp/consul/issues/3687.
Using "NYTimes/gziphandler", the http api responses can now be compressed if required.
The Go API requires compressed response if possible and handle the compressed response.
We here change only the http api (not the UI for instance).
Note that the vendor.json is already correct but the actual files were never checked in so report as missing:
```
$ govendor list | grep testify
v github.com/stretchr/testify/assert
m github.com/stretchr/testify/require
```
See https://github.com/hashicorp/consul/issues/3977
While trying to improve furthermore #3948 (This pull request is still valid since we are not using Compression to compute the result anyway).
I saw a strange behaviour of dns library.
Basically, msg.Len() and len(msg.Pack()) disagree on Message len.
Thus, calculation of DNS response is false consul relies on msg.Len() instead of the result of Pack()
This is linked to miekg/dns#453 and a fix has been provided with miekg/dns#454
Would it be possible to upgrade miekg/dns to a more recent function ?
Consul might for instance upgrade to a post 1.0 release such as https://github.com/miekg/dns/releases/tag/v1.0.4
Update posener/complete to revision=v1.1.
Leave only once occurrence of posener/complete in vendor, there was an occurrence for
each package individualy.
The formatting of vendor/vendor.json has changed after using
the command "govendor fetch github.com/posener/complete@=v1.1"
* Refactors the HTTP listen path to create servers in the same spot.
* Adds HTTP/2 support to Consul's HTTPS server.
* Vendors Go HTTP/2 library and associated deps.
This patch backports a fix which will show the correct usage screen for
command line flags.
This is considered a temporary fix until the code has been refactored.
Newer versions of the cli library require that the flag set is populated
when Help() is called or that it is populated within Help() itself.
Fixes#3536
This patch updates the go-discover library to use the new config parser
which uses a different encoding scheme for the go-discover config DSL.
Values are no longer URL encoded but taken literally unless they contain
spaces, backslashes or double quotes. To support keys or values with
these special characters the string needs to be double quoted and usual
escaping rules apply.
Fixes#3417
* vendor: add github.com/sergi/go-diff/diffmatchpatch for diff'ing test output
* config: refactor Sanitize to recursively clean runtime config and format complex fields
* Removes an extra int cast.
* Adds a top-level check test case for sanitization.
* new config parser for agent
This patch implements a new config parser for the consul agent which
makes the following changes to the previous implementation:
* add HCL support
* all configuration fragments in tests and for default config are
expressed as HCL fragments
* HCL fragments can be provided on the command line so that they
can eventually replace the command line flags.
* HCL/JSON fragments are parsed into a temporary Config structure
which can be merged using reflection (all values are pointers).
The existing merge logic of overwrite for values and append
for slices has been preserved.
* A single builder process generates a typed runtime configuration
for the agent.
The new implementation is more strict and fails in the builder process
if no valid runtime configuration can be generated. Therefore,
additional validations in other parts of the code should be removed.
The builder also pre-computes all required network addresses so that no
address/port magic should be required where the configuration is used
and should therefore be removed.

This picks up the fix for https://github.com/hashicorp/raft/issues/212,
which can cause out-of-date followers to get stuck in a loop trying to
sync because they don't discard old snapshot data.
There's some incidental reordering of the vendor.json since the last
update to that file was merged by hand.
This gets a number of improvements:
* Fixed a missing case where gossip would stop flowing to dead nodes for a short while.
* Uses the go-sockaddr library to look for private IP addresses, which prefers non-loopback
private addresses over loopback ones when trying to automatically determine the advertise address.
* Properly seeds Go's random number generator using the seed library.
* Serf snapshots no longer have the executable bit set on thie file.
* Updates Raft library to get new snapshot/restore API.
* Basic backup and restore working, but need some cleanup.
* Breaks out a snapshot module and adds a SHA256 integrity check.
* Adds snapshot ACL and fills in some missing comments.
* Require a consistent read for snapshots.
* Make sure snapshot works if ACLs aren't enabled.
* Adds a bit of package documentation.
* Returns an empty response from restore to avoid EOF errors.
* Adds API client support for snapshots.
* Makes internal file names match on-disk file snapshots.
* Adds DC and token coverage for snapshot API test.
* Adds missing documentation.
* Adds a unit test for the snapshot client endpoint.
* Moves the connection pool out of the client for easier testing.
* Fixes an incidental issue in the prepared query unit test.
I realized I had two servers in bootstrap mode so this wasn't a good setup.
* Adds a half close to the TCP stream and fixes panic on error.
* Adds client and endpoint tests for snapshots.
* Moves the pool back into the snapshot RPC client.
* Adds a TLS test and fixes half-closes for TLS connections.
* Tweaks some comments.
* Adds a low-level snapshot test.
This is independent of Consul so we can pull this out into a library
later if we want to.
* Cleans up snapshot and archive and completes archive tests.
* Sends a clear error for snapshot operations in dev mode.
Snapshots require the Raft snapshots to be readable, which isn't supported
in dev mode. Send a clear error instead of a deep-down Raft one.
* Adds docs for the snapshot endpoint.
* Adds a stale mode and index feedback for snapshot saves.
This gives folks a way to extract data even if the cluster has no
leader.
* Changes the internal format of a snapshot from zip to tgz.
* Pulls in Raft fix to cancel inflight before a restore.
* Pulls in new Raft restore interface.
* Adds metadata to snapshot saves and a verify function.
* Adds basic save and restore snapshot CLI commands.
* Gets rid of tarball extensions and adds restore message.
* Fixes an incidental bad link in the KV docs.
* Adds documentation for the snapshot CLI commands.
* Scuttle any request body when a snapshot is saved.
* Fixes archive unit test error message check.
* Allows for nil output writers in snapshot RPC handlers.
* Renames hash list Decode to DecodeAndVerify.
* Closes the client connection for snapshot ops.
* Lowers timeout for restore ops.
* Updates Raft vendor to get new Restore signature and integrates with Consul.
* Bounces the leader's internal state when we do a restore.
