It looks like it is possible for screen to use control sequences instead
of literal newlines which fails the tests.
This reuses the existing readUntil function used in other pty tests.
I forgot that waiting on the cond releases the lock so it was possible
to get pty output after writing the buffer but before adding the pty to
the map. To fix, add the pty to the map while under the same lock where
we read from the buffer.
The rest does not need to be behind the lock so I moved it out of
doAttach, and that also means we no longer need
waitForStateOrContextLocked.
Also, this can hit a logger error saying the attach failed which fails
the tests however it is not that the attach failed, just that the
process already ran and exited, so when the process exits do not
set an error, instead for now assume this is an expected close.
* Add screen backend for reconnecting ptys
The screen portion is a port from wsep. There is an interface that lets
you choose between screen and the previous method. By default it will
choose screen if it is installed but this can be overidden (mostly for
tests).
The tests use a scanner instead of a reader now because the reader will
loop infinitely at the end of a stream.
Replace /bin/bash with bash since bash is not always in /bin.
* Remove connection_id from reconnecting PTY logger
This serves multiple connections so it makes no sense to scope it to a
single connection.
Also lets us use "connection_id" when logging write errors instead of
"other_conn_id".
* Use PATH to test buffered reconnecting pty
* chore: rename startup logs to agent logs
This also adds a `source` property to every agent log. It
should allow us to group logs and display them nicer in
the UI as they stream in.

This commit adds two new `agentsdk` functions, `StartupLogsSender` and
`StartupLogsWriter` that can be used by any client looking to send
startup logs to coderd.
We also refactor the `agent` to use these new functions.
As a bonus, agent startup logs are separated into "info" and "error"
levels to separate stdout and stderr.

During agent close it was possible for the startup script logs consumer
to enter a deadlock state where by agent close was waiting via
`a.trackConnGoroutine` and the log reader for a flush event.
This refactor removes the mutex in favor of channel communication and
relies on two goroutines without shared state.
This commit reverts some of the changes in #8029 and implements an
alternative method of keeping track of when the startup script has ended
and there will be no more logs.
This is achieved by adding new agent fields for tracking when the agent
enters the "starting" and "ready"/"start_error" lifecycle states. The
timestamps simplify logic since we don't need understand if the current
state is before or after the state we're interested in. They can also be
used to show data like how long the startup script took to execute. This
also allowed us to remove the EOF field from the logs as the
implementation was problematic when we returned the EOF log entry in the
response since requesting _after_ that ID would give no logs and the API
would thus lose track of EOF.

By tracking and closing sessions manually before closing the underlying
connections, we ensure that the termination is propagated to SSH/SFTP
clients and they're not left waiting for a connection timeout.

* chore: convert workspace agent stats from json to table
* chore: convert agent stats to use a table
Backwards compatibility becomes hard when all agent stats are in a JSON blob.
We also want to query this table for new agents that are failing health checks
so we can display it in the UI.
* Fix migration using default values
* 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

Tailscale doesn't support this, and adding support
