* Improve CLI documentation
* feat: Allow workspace resources to attach multiple agents
This enables a "kubernetes_pod" to attach multiple agents that
could be for multiple services. Each agent is required to have
a unique name, so SSH syntax is:
`coder ssh <workspace>.<agent>`
A resource can have zero agents too, they aren't required.
* Add tree view
* Improve table UI

* Rename `tunnel` to `skip-tunnel`
This command was `true` by default, which causes
a confusing user experience.
* Add disclaimer about editing templates
* Add help to template create
* Improve workspace create flow
* Add end-to-end test for config-ssh
* Improve testing of config-ssh
* Fix workspace list
* feat: Add support for VS Code and JetBrains Gateway via SSH
This fixes various bugs that made this not work:
- Incorrect max message size in `peer`
- Incorrect reader buffer size in `peer`
- Lack of SFTP support in `agent`
- Lack of direct-tcpip support in `agent`
- Misuse of command from session. It should always use the shell
- Blocking on SSH session, only allowing one at a time
Fixes#833 too.
* Fix config-ssh command with socat
* Initial agent
* fix: Use buffered reader in peer to fix ShortBuffer
This prevents a io.ErrShortBuffer from occurring when the byte
slice being read is smaller than the chunks sent from the opposite
pipe.
This makes sense for unordered connections, where transmission is
not guarunteed, but does not make sense for TCP-like connections.
We use a bufio.Reader when ordered to ensure data isn't lost.
* SSH server works!
* Start Windows support
* Something works
* Refactor pty package to support Windows spawn
* SSH server now works on Windows
* Fix non-Windows
* Fix Linux PTY render
* FIx linux build tests
* Remove agent and wintest
* Add test for Windows resize
* Fix linting errors
* Add Windows environment variables
* Add strings import
* Add comment for attrs
* Add goleak
* Add require import

* fix: Synchronize peer logging with a channel
We were depending on the close mutex to properly
report connection state. This ensures the RTC
connection is properly closed before returning.
* Disable pion logging
* Remove buffer
* Try ICE servers
* Remove flushed
* Add diagram explaining handshake
* Fix candidate accept ordering
* Add debug logging to peerbroker
* Fix send ordering
* Lock adding ICE candidate
* Add test for negotiating out of order
* Reduce connection to a single negotiation channel
* Improve test times by pre-installing Terraform
* Lock remote session description being applied
* Organize conn
* Revert to multi-channel setup
* Properly close ICE gatherer
* Improve comments
* Try removing buffered candidates
* Buffer local and remote messages
* Log dTLS transport state
* Add pion logging
Having a mixture of abbreviations in the codebase reduces
clarity. Although opts is common for options, I'd rather
set a precedent of clarifying verbosity.
* chore: Buffer remote candidates like local
This was added for local candidates, and is required for remote
to prevent a race where they are added before a negotiation is
complete.
I removed the mutex earlier, because it would cause a different race.
I didn't realize the remote candidates wouldn't be buffered,
but with this change they are!
* Use local description instead
* Add logging for candidate flush
* Fix race with atomic bool
* Simplify locks
* Add mutex to flush
* Reset buffer
* Remove leak dependency to limit confusion
* Fix ordering
* Revert channel close
* Flush candidates after remote session description is set
* Bump up count to ensure race is fixed
* Use custom ICE dependency
* Fix data race
* Lower timeout to make for fast CI
* Add back mutex to prevent race
* Improve debug logging
* Lock on local description
* Flush local candidates uniquely
* Fix race
* Move mutex to prevent candidate send race
* Move lock to handshake so no race can occur
* Reduce timeout to improve test times
* Move unlock to defer
* Use flushed bool instead of checking remote
* chore: Fix race in collecting ICE Candidates
This logic was flawed previously. ICE Candidates could collect
before a negotiation was triggered, which led to a race where
candidates would be lost. Candidates can no longer be lost,
and we removed some code 😎.
* Add comment describing fix
* Use upstream dependency to fix goroutine leak
* Use upstream dependency to fix goroutine leak
* ci: Run tests using PostgreSQL database and mock
This allows us to use the mock database for quick iterative testing,
and have confidence from CI using a real PostgreSQL database.
PostgreSQL tests are only ran on Linux. They are *really* slow on MacOS
and Windows runners, and don't provide much additional confidence.
* Only run PostgreSQL tests once for speed
* Fix race condition of log after close
Not all resources were cleaned up immediately after a peer connection was
closed. DataChannels could have a goroutine exit after Close() prior to this.
* Fix comment
* chore: Fix golangci-lint configuration and patch errors
Due to misconfiguration of a linting rules directory, our linter has not been
working properly. This change fixes the configuration issue, and all remaining
linting errors.
* Fix race in peer logging
* Fix race and return
* Lock on bufferred amount low
* Fix mutex lock
This package was pulled straight from github.com/coder/m. Nothing has been changed.
It will be used for networking clients<->workspaces, and coderd<->provisionerd.
