There is currently an issue with subdomain workspace apps on workspace
proxies, where if you have a workspace proxy wildcard nested beneath the
primary wildcard, cookies from the primary may be sent to the server
before cookies from the proxy specifically.
Currently:
1. Use a subdomain app via the primary proxy `*.coder.corp.com`
a. Client sends no cookies
a. Server does token smuggling flow
a. Server sets a cookie `coder_subdomain_app_session_token` on
`*.coder.corp.com`
a. Server redirects client to reload the page
a. Request should succeed as usual
1. Wait until the primary proxy's session token cookie has expired in
the database (or make it invalid yourself)
1. Use a subdomain app via a separate proxy `*.sydney.coder.corp.com`
a. Client sends `coder_subdomain_app_session_token` cookie from
`*.coder.corp.com`
a. Server validates supplied cookie, it fails because it's expired
a. Server does token smuggling flow
a. Server sets a cookie `coder_subdomain_app_session_token` on
`*.sydney.coder.corp.com`
a. Server redirects client to reload page
a. Client sends BOTH cookies.
a. The server will only process the first cookie it receives, so if the
expired cookie for the primary proxy is sent first the request will end
up in a permanent loop on step b.
The fix is to append `_{hash(wildcard_access_url)}` to the subdomain
cookies as we cannot control browser behavior further. This avoids the
conflict as each proxy will only read it's specific cookie.
* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
* chore: move app proxying code to workspaceapps pkg
Moves path-app, subdomain-app and reconnecting PTY proxying to the new
workspaceapps.WorkspaceAppServer struct. This is in preparation for
external workspace proxies.
Updates app logout flow to avoid redirecting to coder-logout.${app_host}
on logout. Instead, all subdomain app tokens owned by the logging-out
user will be deleted every time you logout for simplicity sake.
Tests will remain in their original package, pending being moved to an
apptest package (or similar).
