* ConnMonitor to track stalled connections
* New Stalled Overlay to show feedback when we think a connection is
stalled
* New Icon in ConnButton to show stalled connections
* Callbacks in domain socket and PTYs to track activity
Working on bug fixes and UX. Streams restarting, fixed lots of bugs,
timing issues, concurrency bugs. Get status shipped to the FE to drive
"shield" state display. Deal with stale streams.
Also big UX changes to the block headers. Specialize the terminal
headers to prioritize the connection (sense of place), remove old
terminal icon and word "Terminal" from the header. Also drop "Web" and
"Preview" labels on web/preview blocks.
Added `wsh focusblock` command.
Lots of updates across all parts of the system to get this working. Big
changes to routing, streaming, connection management, etc.
* Persistent sessions behind a metadata flag for now
* New backlog queue in the router to prevent hanging
* Fix connection Close() issues that caused hangs when network was down
* Fix issue with random routeids (need to be generated fresh each time
the JWT is used and not fixed) so you can run multiple-wsh commands at
once
* Fix issue with domain sockets changing names across wave restarts
(added a symlink mechanism to resolve new names)
* ClientId caching in main server
* Quick reorder queue for input to prevent out of order delivery across
multiple hops
* Fix out-of-order event delivery in router (remove unnecessary go
routine creation)
* Environment testing and fix environment variables for remote jobs (get
from connserver, add to remote job starts)
* Add new ConnServerInit() remote method to call before marking
connection up
* TODO -- remote file transfer needs to be fixed to not create OOM
issues when transferring large files or directories
lots of stuff here.
introduces a streaming framework for the RPC system with flow control.
new authentication primitives for the RPC system. this is used to create
a persistent "job manager" process (via wsh) that can survive
disconnects. and then a jobcontroller in the main server that can
create, reconnect, and manage these new persistent jobs.
code is currently not actively hooked up to anything minus some new
debugging wsh commands, and a switch in the term block that lets me test
viewing the output.
after PRing this change the next steps are more testing and then
integrating this functionality into the product.
the PR spiraled and ended up being much larger than anticipated.
it is a refactor of wshrouter to have it track "links" as opposed to
just routes. this lets us simplify a lot of things when it comes to
multi-level routing.
* now the router can handle unauthenticated links directly, instead of a
weird limbo in wshproxy
* no more wshmultiproxy
* no more "authtoken" weirdness
* more straightforward handling in connserver (when using router option)
also adds more debugging, more logging, some windows fixes, other wsl
fixes
This adds an RPC command for updating wsh on a remote machine without
starting a new session. It is not being used yet, but will be used for
connections using a single server in the future.
lots of misc connection refactoring / fixes:
* adds blocklogger as a way to writing logging information from the backend directly to the a terminal block
* use blocklogger in conncontroller
* use blocklogger in sshclient
* fix remote name in password prompt
* use sh -c to get around shell weirdness
* remove cmd.exe special cases
* use GetWatcher().GetFullConfig() rather than re-reading the config file
* change order of things we do when establishing a connection. ask for wsh up front. then do domain socket, then connserver
* reduce number of sessions required in the common case when wsh is already installed. running the connserver is now a "multi-command" which checks if it is installed, then asks for the version
* send jwt token over stdin instead of in initial command string
* fix focus bug for frontend conn modal
* track more information in connstatus
* simplify wshinstall function
* add nowshreason
* other misc cleanup
* use pwsh over powershell if installed (on windows) for default shell
* refactor blockcontroller.DoRunShellCommand into a "setup" and "manage" phase
* fix wshcmd-conn to also disconnect wsl connections
* new genconn interfaces to make a standardized environment to run SSH/WSL commands via `sh -c`. also create better quoting functions that are composable
* replace html/template with text/template for shell command templating (avoids special chars getting turned into HTML entities, breaking the commands)
* do not reinstall wsh if the installed version has a higher version (prevents flip-flopping on shared systems)
* simplify clientOs/clientArch detection. use `uname -sm`. also validate the os/arch combo as compatible with our builds.
* replace CpHostToRemote with CpWshToRemote. hard codes wsh paths inside of the function instead of having them passed in (quoting restrictions)
* new SyncBuffer class to use with commands that properly synchronizes Writes/String output
* fix setTermSize to actually update DB with terminal size
As connections can now be stored in the internal connection, a missing
or invalid ssh config should not cause the entire list of connections to
be empty. This change ignores the error from the ssh config and proceeds
to construct the list without it.
A recent change meant that if certain operations for setting up wsh
failed, a fallback would be employed to launch the terminal without the
wsh connection. This adds the domain socket listener to the list of
things that are allowed to fail before retrying without wsh instead of
failing outright.
This adds the following connections changes:
- connections can be hidden from the dropdown in our internal
connections.json config
- `wsh ssh` -i will write identity files to the internal
connections.json config for that connection
- the internal connections.json config will also be used to get identity
files when connecting
- the internal connections.json config allows setting theme, fontsize,
and font for specific connections
- successful connections (including those using wsh ssh) are saved to
the internal connections.json config
- the connections.json config will be used to help pre-populate the
dropdown list
- adds an item to the dropdown to edit the connections config in an
ephemeral block

This change will skip over match statements in the ssh config without
panicking. Note that this change still does not add match statement
parsing--it merely makes it possible to continue parsing if the match
keyword is present.
This provides a checkbox when installing wsh that will prevent the
message from popping up in the future. It can also be disabled by adding
`"askbeforewshinstall": false` to the config file.
This migrates all remaining eventbus events sent over the websocket to
use the wps interface. WPS is more flexible for registering events and
callbacks and provides support for more reliable unsubscribes and
resubscribes.
Adds a list of potential remotes to add and filters it as you type. It
also provides options for reconnecting on a disconnection and
specifically connecting to a local connection
