* fix: use a waitgroup to ensure all connections are cleaned up in agent
There was a race where connections would be created at the same time as close.
The `net.Conn` produced by Tailscale doesn't close then the listener does.
* Remove accidental test
* chore: rename `AgentConn` to `WorkspaceAgentConn`
The codersdk was becoming bloated with consts for the workspace
agent that made no sense to a reader. `Tailnet*` is an example
of these consts.
* chore: remove `Get` prefix from *Client functions
* chore: remove `BypassRatelimits` option in `codersdk.Client`
It feels wrong to have this as a direct option because it's so infrequently
needed by API callers. It's better to directly modify headers in the two
places that we actually use it.
* Merge `appearance.go` and `buildinfo.go` into `deployment.go`
* Merge `experiments.go` and `features.go` into `deployment.go`
* Fix `make gen` referencing old type names
* Merge `error.go` into `client.go`
`codersdk.Response` lived in `error.go`, which is wrong.
* chore: refactor workspace agent functions into agentsdk
It was odd conflating the codersdk that clients should use
with functions that only the agent should use. This separates
them into two SDKs that are closely coupled, but separate.
* Merge `insights.go` into `deployment.go`
* Merge `organizationmember.go` into `organizations.go`
* Merge `quota.go` into `workspaces.go`
* Rename `sse.go` to `serversentevents.go`
* Rename `codersdk.WorkspaceAppHostResponse` to `codersdk.AppHostResponse`
* Format `.vscode/settings.json`
* Fix outdated naming in `api.ts`
* Fix app host response
* Fix unsupported type
* Fix imported type
The VS Code extension has been refactored to use VS Code
Remote SSH instead of using the private API.
This changes the structure to continue using SSH, but
output network information periodically to a file.
Since AgentReportStats takes a stats function which was doing mutex
locking on agent shutdown, it was possible for there to be a deadlock
depending on how the AgentReportsStats Close function is implemented.
This mostly seems to happen on Windows test runners as it's pretty hard
to hit this edge case. The bug currently only exists in the test
implementation of AgentReportStats, however, this was refactored to be
more robust in case of future changes.
* fix: Enable reconnectingpty loadtest and fix/improve logging
This commit re-enabled reconnectingpty loadtests after a logging
refactor of `(*agent).handleReconnectingPTY`. The reasons the tests were
flaking was that `logger.Error` was being called and `slogtest` failing
the test.
We could have set the option for `slogtest` to disable failing, but that
could hide real issues. The current approach improves reconnectingpty
logging overall and provides more insight into what's happening. It's
expected that reconnectingpty sessions fail after the agent is closed,
so calling `logger.Error` at that point is not wanted.
Ref: #5322
It turns out that writing tests that contain subtests should probably be
limited to table-based tests and tests that share a common setup shared
between tests.
Writing tests with a subtest like this:
```
func TestSomething(t *testing.T) {
t.Run("Subtest", func(t *testing.t) {})
}
```
Has the following disadvantages:
- It can lead to multiple tests failing with `(unknown)` status when
only one of the subtests hang (never exit)
- In Go 1.20rc1, using `t.Setenv` is no longer allowed if the parent
test is parallel
The users login shell would be executed as:
/bin/bash -c '/bin/bash -l'
This simplifies the command for login shells so that the executed
command is:
/bin/bash -l
* chore: Close idle connections on test cleanup
It's possible that this was the source of a leak on Windows...
* ci: use big runners
* fix: Improve tailnet connections by reducing timeouts
This awaits connection ping before running a dial. Before,
we were hitting the TCP retransmission and handshake timeouts,
which could intermittently add 1 or 5 seconds to a connection
being initialized.
* Add logging to Startupscript test
* Add better logging
* Write startup script logs to fs dir
* Fix startup script test
* Fix startup script test
* Reduce test timeout
* Use central tmp dir in agent
* Adjust output
* Skip startup script test on Windows

* Update Tailscale
* fix: Refactor agent to consume API client
This simplifies a lot of code by creating an interface for
the codersdk client into the agent. It also moves agent
authentication code so instance identity will work between
restarts.
Fixes#3485 and #4082.
