* feat: parse multiple identity files in ssh
While this does not make it possible to discover multiple identity files
in every case, it does make it possible to parse them individually and
check for user input if it's required for each one.
* chore: remove unnecessary print in updatebus.go
* chore: remove unnecessary print in sshclient.go
* chore: remove old publicKey auth check
With the new callback in place, we no longer need this, so it has been
removed.
* refactor: move logic for wave and config options
The logic for making decisions between details made available from wave
and details made available from ssh_config was spread out. This change
condenses it into one function for gathering those details and one for
picking between them.
It also adds a few new keywords but the logic for those hasn't been
implemented yet.
* feat: allow attempting auth methods in any order
While waveterm does not provide the control over which order to attempt
yet, it is possible to provide that information in the ssh_config. This
change allows that order to take precedence in a case where it is set.
* feat: add batch mode support
BatchMode turns off user input to enter passwords for ssh. Because we
save passwords, we can still attempt these methods but we disable the
user interactive prompts in this case.
* fix: fix auth ordering and identity files
The last few commits introduced a few bugs that are fixed here. The
first is that the auth ordering is parsed as a single string and not a
list. This is fixed by manually splitting the string into a list. The
second is that the copy of identity files was not long enough to copy
the contents of the original. This is now updated to use the length of
the original in its construction.
* deactivate timer while connecting to new ssh
The new ssh setup handles timers differently from the old one due to the
possibility of asking for user input multiple times. This limited the
user input to entirely be done within 15 seconds. This removes that
restriction which will allow those timers to increase. It does not
impact the legacy ssh systems or the local connections on the new
system.
* merge branch 'main' into 'ssh--auth-control'
This was mostly straightforward, but it appears that a previous commit
to main broke the user input modals by deleting a function. This adds
that back in addition to the merge.
* fix: allow 60 second timeouts for ssh inputs
With the previous change, it is now possible to extend the timeout for
manual inputs. 60 seconds should be a reasonable starting point.
* fix: change size of dummy key to 2048
This fixes the CodeQL scan issue for using a weak key.
* working on easy global shortcut for wave
* globalshortcut setting working
* cmd for macos, alt for others
* re-remove types.ts (was added back during merge)
* rename DDItem to DropdownItem, put into custom.d.ts
* make some consts
* declare types as global

* put back model_old.ts
* remove types.ts
* add main screens to Cmd-P search
* make viewData optional
* minor hint fix
* address improvements suggested by evan
* more on let to const
This PR changes ModelUpdate mechanism from a statically-typed struct to an interface, allowing us to define the update mechanism and the update types separately. This sets us up to move app logic and update mechanisms into separate packages. Ultimately, sstore will only define low-level persistence logic.
* feat: create backend for user input requests
This is the first part of a change that allows the backend to request
user input from the frontend. Essentially, the backend will send a
request for the user to answer some query, and the frontend will send
that answer back. It is blocking, so it needs to be used within a
goroutine.
There is some placeholder code in the frontend that will be updated in
future commits. Similarly, there is some debug code in the backend
remote.go file.
* feat: create frontend for user input requests
This is part of a change to allow the backend to request user input from
the frontend. This adds a component specifically for handling this
logic. It is only a starting point, and does not work perfectly yet.
* refactor: update user input backend/interface
This updates the user input backend to fix a few potential bugs. It also
refactors the user input request and response types to better handle
markdown and errors while making it more convenient to work with.
A couple frontend changes were made to keep everything compatible.
* fix: add props to user input request modal
There was a second place that the modals were created that I previously
missed. This fixes that second casel
* feat: complete user input modal
This rounds out the most immediate concerns for the new user input
modal. The frontend now includes a timer to show how much time is left
and will close itself once it reaches zero. Css
formatting has been cleaned up to be more reasonable.
There is still some test code present on the back end. This will be
removed once actuall examples of the new modal are in place.
* feat: create first pass known_hosts detection
Manually integrating with golang's ssh library means that the code must
authenticate known_hosts on its own. This is a first pass at creating a
system that parses the known hosts files and denys a connection if there
is a mismatch. This needs to be updated with a means to add keys to the
known-hosts file if the user requests it.
* feat: allow writing to known_hosts first pass
As a follow-up to the previous change, we now allow the user to respond
to interactive queries in order to determine if an unknown known hosts
key can be added to a known_hosts file if it is missing. This needs to
be refined further, but it gets the basic functionality there.
* feat: add user input for kbd-interactive auth
This adds a modal so the user can respond to prompts provided using the
keyboard interactive authentication method.
* feat: add interactive password authentication
This makes the ssh password authentication interactive with its own user
input modal. Unfortunately, this method does not allow trying a default
first. This will need to be expanded in the future to accomodate that.
* fix: allow automatic and interactive auth together
Previously, it was impossible to use to separate methods of the same
type to try ssh authentication. This made it impossible to make an auto
attempt before a manual one. This change restricts that by combining
them into one method where the auto attempt is tried once first and
cannot be tried again. Following that, interactive authentication can be
tried separately.
It also lowers the time limit on kbd interactive authentication to 15
seconds due to limitations on the library we are using.
* fix: set number of retries to one in ssh
Number of retries means number of attempts after the fact, not number of
total attempts. It has been adjusted from 2 to 1 to reflect this.
* refactor: change argument order in GetUserInput
This is a simple change to move the context to the first argument of
GetUserInput to match the convention used elsewhere in the code.
* fix: set number of retries to two again
I was wrong in my previous analysis. The number given is the total
number of tries. This is confusing when keyboard authentication and
password authentication are both available which usually doesn't happen.
* feat: create naive ui for ssh key passphrases
This isn't quite as reactive as the other methods, but it does attempt
to use publickey without a passphrase, then attempt to use the password
as the passphrase, and finally prompting the user for a passphrase. The
problem with this approach is that if multiple keys are used and they
all have passphrases, they need to all be checked up front. In practice,
this will not happen often, but it is something to be aware of.
* fix: add the userinput.tsx changes
These were missed in the previous commit. Adding them now.

* zsh alias parsing/restoring. diff changes (and rtnstate changes). introduces linediff v1.
* force zmodload of zsh/parameter
* starting work on zsh functions
* need a v1 of mapdiff as well (to handle null chars)
* pack/unpack of ints was wrong (one used int and one use uint). turned out we only ever encoded '0' so it worked. that also means it is safe to change unpack to unpackUInt
* reworking for binary encoding of aliases and functions (because of zsh allows any character, including nulls, in names and values)
* fixes, working on functions, issue with line endings
* zsh functions. lots of ugliness here around dealing with line dicipline and cooked stty. new runcommand function to grab output from a non-tty fd. note that we still to run the actual command in a stty to get the proper output.

* rename confirmkey to confirmflag (to be consistent). move confirmflag checking into the alertmodal. short circuit with Promise.resolve(true) if noConfirm checked.
* disable buttons while status is 'connecting'
* minor refactor
* add an alert modal for the sshconfig import button
When the sshconfig import button is pressed, there currently is no
visual indicator of what changed. This adds an alert modal to pop up
only in the case where the gui button is used.
* improve alert modal for sshconfig imports
The previous message for SSH configuration imports was vague and did not
provide detailed information as what happened during the import. This
clarifies that by specifying which remotes were deleted, created, and
updated. Updates are only ran and recorded if they would actually change
something.
* fix port value limiting
The SSH config import port limiting was correct but set off a warning in
linters. It has been updated to do the same behavior in a different way.
Also, port limiting was never added to manually adding a new remote.
This change adds it there as well.
* change user-facing term to connection
Previously, the ssh configuration alert modal used to use the word
"remote" to describe connections. "Remote" is the internal name but it
isn't consistent with what is being displayed to users. So it has been
replaced with "Connection" instead to match.
* change remote to connection for ssh import buttons
Like the previous change, the word "remote" was used instead of
"connection." This was for the tooltips added to connections that had
been imported in the connections menu.
* update one more remote -> connection
* work on cmd-d to delete a selected line
* call stoppropagation when code.tsx captures keyboard input
* finish up with line delete. add a trash icon to line. prevent delete when cmd is running (show error msg)
* remove byte sanitization for user commands
When serializing jsonBytes in packet.go::MarshalPacket, a step existed
that attempted to manually sanitize the bytes before sending them. This
was initially done to avoid invalid characters in json; however, go
should handle this for us. But this sanitization broke
internationalization because it excluded characters required for unicode
in other languages. Because of that, it has been removed.
* properly decode non-ascii on frontend
The functions atob and btoa do not convert base 64 to strings in the
expected way. The base64ToArray function handles it properly but other
cases do not. These other cases have been replaced with a helper
function that makes use of the base64-js package. This package has
already been included as a dependency of another package we use, but it
was added to the package.json file to make the inclusion explicit.
* automatically set/share LANG var with waveshell
Waveterm previously did not set the LANG environment variable which
caused problems for international users. On Linux, this is done
automatically, but it needs to be done manually on macos.
Even on linux, the wavesrv LANG variable is shared with waveshell to
ensure the same one is used on remotes.
* only set the lang var if not previously set
In order to prevent waveterm from overriding the lang var entirely, this
ensures that it is only manually determined if it hasn't previously been
set.
* use envMap instead of os to determine var
This is slightly more performant and relies more directly on our code
instead of external code.
* improved disconnected modal
* wrap pre with div
* make number of a lines param a constant
* revert app.tsx
* use tail command and capture the output instead
* reset TabSwitcherModal
