* ci: Update DataDog GitHub branch to fallback to GITHUB_REF
This was detecting branches, but not our "main" branch before.
Hopefully this fixes it!
* Add basic Terraform Provider
* Rename post files to upload
* Add tests for resources
* Skip instance identity test
* Add tests for ensuring agent get's passed through properly
* Fix linting errors
* Add echo path
* Fix agent authentication
* fix: Convert all jobs to use a common resource and agent type
This enables a consistent API for project import and provisioned resources.
* feat: Add agent authentication based on instance ID
Each cloud has it's own unique instance identity signatures, which
can be used for zero-token authentication. This change adds support
for tracking by "instance_id", and automatically authenticating
with Google Cloud.
* Add test for CLI
* Fix workspace agent request name
* Fix race with adding to wait group
* Fix name of instance identity token
WebSockets hijack the HTTP connection from the server, causing
server.Close() to not wait for these connections to fully cleanup.
This adds a global wait-group to the coderd API, which ensures all
WebSocket HTTP handlers have properly exited before returning.

* Update API to use jobs first
* Fix CLI tests
* Fix linting
* Fix hex length for files table
* Reduce memory allocation for windows
* refactor: Rename ProjectParameter to ProjectVersionParameter
This was confusing with ParameterValue before. It still is a bit,
but this should help distinguish scope.
* Add project version resources table
* Allow project parameters to optionally have user and workspace
* Add dry run for provisioners
* Add resource detection on project import
* refactor: Generalize log ownership to allow for scratch jobs
Importing may fail when creating a project. We don't want to lose this output,
but we don't want to allow users to create a failing project.
This generalizes logs to soon enable one-off situations where a user can upload
their archive, create a project, and watch the output parse to completion.
* Improve file table schema by using hash
* Fix racey test by allowing logs before
* Add debug logging for PostgreSQL insert
* ci: Replace DataDog CI with custom upload script
This will reduce CI time by ~6 minutes across all of
our runners. It's a bit janky, but I believe worth
the slight maintainance burden.
* Fix test race when job would complete too early
* Fix job cancelation override
* Fix race where provisioner job is inserted before project version
* chore: Rename ProjectHistory to ProjectVersion
Version more accurately represents version storage. This
forks from the WorkspaceHistory name, but I think it's
easier to understand Workspace history.
* Rename files
* Standardize tests a bit more

* chore: Rename ProjectHistory to ProjectVersion
Version more accurately represents version storage. This
forks from the WorkspaceHistory name, but I think it's
easier to understand Workspace history.
* Rename files
This replaces the cdr-basic provisioner type with
"echo". It reads binary data from the directory
and returns the responses in order.
This is used to test project and workspace job logic.
* feat: Add parameter querying to the API
* feat: Add streaming endpoint for workspace history
Enables a buildlog-like flow for reading job output.
* Fix empty parameter source and destination
* Add comment for usage of workspace history logs endpoint
* feat: Add history middleware parameters
These will be used for streaming logs, checking status,
and other operations related to workspace and project
history.
* refactor: Move all HTTP routes to top-level struct
Nesting all structs behind their respective structures
is leaky, and promotes naming conflicts between handlers.
Our HTTP routes cannot have conflicts, so neither should
function naming.
* Add provisioner daemon routes
* Add periodic updates
* Skip pubsub if short
* Return jobs with WorkspaceHistory
* Add endpoints for extracting singular history
* The full end-to-end operation works
* fix: Disable compression for websocket dRPC transport (#145)
There is a race condition in the interop between the websocket and `dRPC`: https://github.com/coder/coder/runs/5038545709?check_suite_focus=true#step:7:117 - it seems both the websocket and dRPC feel like they own the `byte[]` being sent between them. This can lead to data races, in which both `dRPC` and the websocket are writing.
This is just tracking some experimentation to fix that race condition

## Open Questions: ##
### Is `dRPC` or `websocket` at fault for the data race?
It looks like this condition is specifically happening when `dRPC` decides to [`SendError`]). This constructs a new byte payload from [`MarshalError`](f6e369438f/drpcwire/error.go (L15)) - so `dRPC` has created this buffer and owns it.
From `dRPC`'s perspective, the callstack looks like this:
- [`sendPacket`](f6e369438f/drpcstream/stream.go (L253))
- [`writeFrame`](f6e369438f/drpcwire/writer.go (L65))
- [`AppendFrame`](f6e369438f/drpcwire/packet.go (L128))
- with finally the data race happening here:
```go
// AppendFrame appends a marshaled form of the frame to the provided buffer.
func AppendFrame(buf []byte, fr Frame) []byte {
...
out := buf
out = append(out, control). // <---------
```
This should be fine, since `dPRC` create this buffer, and is taking the byte buffer constructed from `MarshalError` and tacking a bunch of headers on it to create a proper frame.
Once `dRPC` is done writing, it _hangs onto the buffer and resets it here__: f6e369438f/drpcwire/writer.go (L73)
However... the websocket implementation, once it gets the buffer, it runs a `statelessDeflate` [here](8dee580a7f/write.go (L180)), which compresses the buffer on the fly. This functionality actually [mutates the buffer in place](a1a9cfc821/flate/stateless.go (L94)), which is where get our race.
In the case where the `byte[]` aren't being manipulated anywhere else, this compress-in-place operation would be safe, and that's probably the case for most over-the-wire usages. In this case, though, where we're plumbing `dRPC` -> websocket, they both are manipulating it (`dRPC` is reusing the buffer for the next `write`, and `websocket` is compressing on the fly).
### Why does cloning on `Read` fail?
Get a bunch of errors like:
```
2022/02/02 19:26:10 [WARN] yamux: frame for missing stream: Vsn:0 Type:0 Flags:0 StreamID:0 Length:0
2022/02/02 19:26:25 [ERR] yamux: Failed to read header: unexpected EOF
2022/02/02 19:26:25 [ERR] yamux: Failed to read header: unexpected EOF
2022/02/02 19:26:25 [WARN] yamux: frame for missing stream: Vsn:0 Type:0 Flags:0 StreamID:0 Length:0
```
# UPDATE:
We decided we could disable websocket compression, which would avoid the race because the in-place `deflate` operaton would no longer be run. Trying that out now:

* fix: Remove race condition with acquiredJobDone channel (#148)
Found another data race while running the tests: https://github.com/coder/coder/runs/5044320845?check_suite_focus=true#step:7:83
__Issue:__ There is a race in the p.acquiredJobDone chan - in particular, there can be a case where we're waiting on the channel to finish (in close) with <-p.acquiredJobDone, but in parallel, an acquireJob could've been started, which would create a new channel for p.acquiredJobDone. There is a similar race in `close(..)`ing the channel, which also came up in test runs.
__Fix:__ Instead of recreating the channel everytime, we can use `sync.WaitGroup` to accomplish the same functionality - a semaphore to make close wait for the current job to wrap up.
* fix: Bump up workspace history timeout (#149)
This is an attempted fix for failures like: https://github.com/coder/coder/runs/5043435263?check_suite_focus=true#step:7:32
Looking at the timing of the test:
```
t.go:56: 2022-02-02 21:33:21.964 [DEBUG] (terraform-provisioner) <provision.go:139> ran apply

workspacehistory_test.go:122:
Error Trace: workspacehistory_test.go:122
Error: Condition never satisfied
Test: TestWorkspaceHistory/CreateHistory
```
It appears that the `terraform apply` job had just finished - with less than a second to spare until our `require.Eventually` completes - but there's still work to be done (ie, collecting the state files). So my suspicion is that terraform might, in some cases, exceed our 5s timeout.
Note that in the setup for this test - there is a similar project history wait that waits for 15s, so I borrowed that here.
In the future - we can look at potentially using a simple echo provider to exercise this in the unit test, in a way that is more reliable in terms of timing. I'll log an issue to track that.
