* 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
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.
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.
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.
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.
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.
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.
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.
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.
* 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.

* revert some changes, replace some svgs with fontawesome
* remove listitem
* remove log
* create proof of concept ssh library integration
This is a first attempt to integrate the golang crypto/ssh library for
handling remote connections. As it stands, this features is limited to
identity files without passphrases. It needs to be expanded to include
key+passphrase and password verifications as well.
* add password and keyboard-interactive ssh auth
This adds several new ssh auth methods. In addition to the PublicKey
method used previously, this adds password authentication,
keyboard-interactive authentication, and PublicKey+Passphrase
authentication.
Furthermore, it refactores the ssh connection code into its own wavesrv
file rather than storing int in waveshell's shexec file.
* clean up old mshell launch methods
In the debugging the addition of the ssh library, i had several versions
of the MShellProc Launch function. Since this seems mostly stable, I
have removed the old version and the experimental version in favor of
the combined version.
* allow switching between new and old ssh for dev
It is inconvenient to create milestones without being able to merge into
the main branch. But due to the experimental nature of the ssh changes,
it is not desired to use these changes in the main branch yet. This
change disables the new ssh launcher by default. It can be used by
changing the UseSshLibrary constant to true in remote.go. With this, it
becomes possible to merge these changes into the main branch without
them being used in production.
* fix: allow retry after ssh auth failure
Previously, the error status was not set when an ssh connection failed.
Because of this, an ssh connection failure would lock the failed remote
until waveterm was rebooted. This fix properly sets the error status so
this cannot happen.
* better osrelease parsing (ignore garbage at end of string)
* add defaultshelltype to telemetry input
* track reinit errors by shelltype to see if zsh integration is working
Adds job status indicators that will show any updates to running commands while you are focused away from a tab. These will show up as status icons in the tab view.
These indicators will reset for a given tab when you focus back to it.
I've updated the inner formatting of the tab to use flexboxes, allowing the title to display more text when there are no icons to display.
Also includes some miscellaneous for-loop pattern improvements in model.ts and removing of unused variables, etc.

* 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
The ssh_config library only loaded the config data the first time
certain functions are used. After that, cached values are used instead.
This library has been updated in a fork to add a method that allows the
configuration files to be reloaded. This update takes advantage of that
change so the config files can be updated without restarting waveterm.
* 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.
* allow numerical start and allow dots in ssh alias
We previously restricted the ssh alias to start with an
alphabetic character and did not allow dots within it. This caused
problems with users wanting to use an ip address as an alias. This lifts
that restriction so both can freely be used.
Note that while it is common to use the hostname as the alias, hostnames
are not allowed to use the underscore character. However, we do allow
the alias to contain an underscore. I do not think we can remove this
from aliases now but it is something to watch out for in the future.
* allow backslash in username
This involved converting the regexp string into a raw string to able to
use the backslash character. this is important.
* Revert "allow backslash in username"
This reverts commit cafe281241. Upon
reflection, more time is needed to evaluate that this actually corrects
the issue. It will be performed with proper diligence at a later time.
* add port to end of canoncial names when not 22
The canonical name is the identifying key in the database, so it causes
problems if another remote entry has the same canonical name. By adding
the port number to the end of this, it is possible to differentiate the
two.
* add db migrations for adding port to canonicalname
The up migration adds the port to the existing canonical id if it exists
and is not 22. The down migration strips the port off the canonical name
and deletes extra remotes with the same canonical name. If all remotes
with that canonical name have been archived, it keeps the first one
added to the database. If any have not been archived, it keeps the first
added to the database from the non-archived group.
* remove ability to edit port number via ssh import
Previously, ssh imports could edit the port number since it was possible
to change them in the config file without changin the canonical name.
Now that the canonical name contains the port, a change in the port will
simply create a new database entry. For this reason, the ability to
modify the ssh port is dead code and has been removed.
* allow backslash in username
This involved converting the regexp string into a raw string to able to
use the backslash character. this is important.
* simplify up migration logic
The previous up migration was suboptimal because it was accounting for a
corner case not found in production. That case no longer needs to be
considered, so the procedure was simplified.
* fix commands that require quoted paths
Several commands did not wrap the path in quotes which caused problems
when attempting to store the waveterm installation in a place that had a
space in the path. This corrects this in the particular case where the
username does not have spaces but the path to the executable does.
Note: the case of a user name having spaces has not been tested but
likely does not work.
* fix logging problem for wavesrv
A previous fix replaced the getWaveSrvCmd with getWaveSrvPath. This
needs to be getWaveSrvCmd to enable logging.
* fix variable name
* create migrations for required database change
This is a first attempt that does not appear to be working properly. It
requires review.
* fix errors in db migrations
The previous commit had an extra json call that broke the update and did
not remove the imported interies during a downgrade.
* change migrations to use column instead of json
It makes more sense to associate the source of a config with the remote
type than the sshopts type. This change makes that clear in the database
structure.
* ensure adding a remote manually tags correctly
Using the usual way of adding a remote should result in a sshconfigsrc
of "waveterm-manual". This will be important for filtering out remotes
installed manually and remotes installed via import
* create basic structure for parsing ssh config
This entails creating a new command, making it possible to query only
the imported remotes from the database, and implementing the logic to
handle all of the updates needed.
This needs improvements in a few areas:
- the /etc/ssh/config needs to be parsed as well
- the logic for editing exisiting imported remotes needs to be written
- error handling needs to be improved
- update packet responses need to be provided
* add sshkey support and implement editing
We now search for the ssh identity keyfile and add it if it is found.
Additionally, the logic to edit previously imported ssh hosts has been
added.
* combine hosts from user and system ssh config
We now check both the user ~/.ssh/config as well as the /etc/ssh/config
for hosts. This loops through each file starting with the user one. For
each host, it selects the first pattern without a wildcard and chooses
that to be the alias. If any future hosts are found to have the same
alias, they are skipped. Errors are raised if neither config file can be
opened or no aliases were found.
* improve logging and error reporting
Error reporting is now shortcircuited in cases of individual remotes in
order to allow the other remotes to continue. These errors are now
printed to logs instead.
* allow imports to edit ssh port
Previously, ssh ports could not be edited after the fact. Unfortunately,
this can cause problems since the port can be changed in an ssh config
file. To address this, we allow imports to change the port if a host
with the same canonical name had previously been imported.
* fix response to parse command
* fix error handline for alias parsing
Small mistake of checking for equality instead of inequality
* fix the ability to overwrite hostName with alias
if ssh_config does not find Hostname, it won't output an error. Now we
compare against the result instead of looking for an error.
* fix the error catching for User and Port
This fixes the same problem where parsing the config doesn't give an
error in the case when nothing is found. As before, this checks for a
blank result instead.
* remove unused code
* remove repeated canonical name check
The logic that checks for an existing canonical name already exists in
the AddRemote function, so it is not needed here.
Secondly, we now only allow edits of previously created remotes if they
have not been archived. If they have, the usual logic for creating a new
remote takes precedence.
Lastly, there is no need to archive a remote that has already been
archived so an additional check has been added.
* allow archives to preserve the SSHConfigSrc
* add log message for archiving of imported remotes
* create variables for string variants
Matches existing code style
* add cleanup for opened files
* move migration 25 to migration 26 (already merged a migration 25)
* fix RemoteRuntimeState in ModelUpdate by moving type to sstore.go. Fix some bugs in remote:parse. Fix key/identityfile, return value, and remote editing (should go through msh). remote sudo. add info messages around parse status
* fix issue with archiving the sshconfigsrc
A bug in RemoteType's FromMap caused the loss of sshconfigsrc during the
conversion. This has been corrected and the schema has been updated.
* fix order of archiving removed imported remotes
Previously, if the canonical name changed, the code would try to create
a new remote before archiving the old one. This did not work if the
alias didn't change. Now we archive first and add a new remote after.
* fix ability to change port when importing config
Importing from sshconfig needs to allow the port to change. This was not
happening because of a bug that has been corrected.
* always use host in place of hostname
Since host is the key actually searched for in the ssh config file,
searching for user@hostName may not actually work. To avoid this, we now
always use user@host instead.
* automatically determine ConnectMode
This aims to select a connection mode based off what is provided in the
ssh config file. It aims for auto connections when possible but will
fall back to manual if we can't easily support it
* remove sshkeysource migration number confilict
Previously had conflicting migration numbers of 26. The change not in
the main branch has been moved to 27 to remove the conflict.
* move sshkeysource migration to migration 28
* add WaveOptions flag parsing for ssh config
This is currently being used to allow users to force manual connect mode
if desired. It will also be used to force skipping options in the future
but that is not complete in this commit.
* implement ignore flag for ssh config parsing
The ignore flag will now archive an imported remote if it previously
existed and not create a new remote in its place.
* fix discovery of identity file
Previously, a ~ in the identity file's path was not expanded to the home
dir. Because of this, files with a ~ were previously identified as
invalid files. By expanding it during the search, this is no longer the
case.
* disable frontend edit button for imported remotes
Imported Remotes should not be editable in waveterm by users. This edit
makes it clear that the button will not work for those cases. Further
edits may be needed to explain why it doesn't work and what to do
instead.
* add backend rejection of updating imported remote
As before, we don't want manual editing of an imported remote inside the
app. This ensures that it can't happen on the backend.
* create tooltips for sshconfig edit/delete buttons
For remotes that are imported, edits are not allowed. This adds a
tooltip that explains what to do instead.
Deleting remotes that are imported is allowed, but they will come back
if the user imports again. The tooltip explains a way to avoid this.
* add logo after name for imported remotes
In the connections screen, there previously was not a way to tell
imported connections from manually created connections. This change adds
a logo after the imported ones to differentiate them.
* small formatting updates
* add import tooltip to connection modal
Added the logo for an imported config to the connection modal. It also
provides a short description when it the mouse hovers over it.
* add button to import ssh config
Make the command into a button for a simple gui interface.
Also ran prettier to clean up some syntax.
* remove strict casing on WaveOptions
WaveOptions was previously very specific about the casing of the ignore
and connectmode subcommands. With this update, the casing is
automatically converted to lowercase and can be ignored.
* add status dot before name in connections screen
* add space and tooltip to connection imported icon
* re-prettier
* sync schema.sql with running schema
* remove incognito field from history table. also don't add empty FeState vars
* history updates, add festate, durationms, exitcode, status, and tags into history table
* update screen/session delete, and clear to no longer purge history items. move deleted screens/sessions into a tombstone table.
* update schema
* fix alias -> fn
* quiet the security warning about an unchecked byte conversion. no real security issue here, but add a range check for good measure.
* working on an in-memory store for screen information
* nostrpos sentinel
* textareainput now tracks selection (to update backend)
* make websocket connections much safer. add a defer/panic handler for each ws message handled on backend. don't allow client to reconnect to backend ws handler more than once per second (handles issue with lots of fast fails)
* use onSelect to have frontend textarea sync state to backend ScreenMem store
* restore cmdline when switching screens
* prettier
