Unreleased

[0.21.0]

Changed

  • BREAKING: Migrated distant-ssh2 from wezterm-ssh to pure Rust SSH libraries (russh, russh-sftp)
    • Removed libssh and ssh2 backend feature flags - now uses pure Rust implementation only
    • Removed SshBackend enum - no longer needed as only one backend is supported
    • Improved reliability and removed dependency on bug-ridden C libraries (libssh-rs, ssh2-rs)

Added

  • Full russh-sftp integration with lazy session caching for 10-40x performance improvement
  • SSH config file parsing via ssh2-config-rs for automatic host configuration
  • Proper PTY support with window resizing capability
  • Support for both simple (non-PTY) and PTY process spawning over SSH

Fixed

  • set_permissions now works correctly over SSH (was broken in wezterm-ssh)
  • Process termination over SSH now works reliably (proc_kill)
  • Improved error handling and reporting throughout SSH operations

Removed

  • Dependency on wezterm-ssh, async-compat, smol
  • libssh and ssh2 feature flags and backend selection
  • C library dependencies (libssh, ssh2)

Notes

  • Search and file watching features are not supported over SSH (return Unsupported error)
  • Users can implement custom search/watch functionality using proc_spawn with shell commands
  • MSRV remains at 1.70.0

[0.20.0]

Fixed

  • Bug in distant fs set-permissions where partial permissions such as go-w would result in clearing all permissions
  • Bug in distant-local implementation of SetPermissions where read-only status was being set/cleared prior to Unix permissions being applied, resulting in applying an invalid change to the permissions

[0.20.0]

All changes described in these alpha releases:

Fixed

  • When terminating a connection using distant manager kill, the connection is now properly dropped, resulting servers waiting to terminate due to --shutdown lonely=N to now shutdown accordingly
  • Zombies from spawned servers via distant launch manager://localhost are now properly terminated by checking the exit status of processes

0.20.0-alpha.13

Added

  • Support for --shell with optional path to an explicit shell as an option when executing distant spawn in order to run the command within a shell rather than directly
  • semver crate to be used for version information in protocol and manager
  • is_compatible_with function to root of distant-protocol crate that checks if a provided version is compatible with the protocol

Changed

  • distant_protocol::PROTOCOL_VERSION now uses the crate's major, minor, and patch version at compile-time (parsed via const-str crate) to streamline version handling between crate and protocol
  • Protocol and manager now supply a version request instead of capabilities and the capabilities of protocol are now a Vec<String> to contain a set of more broad capabilities instead of every possible request type

Fixed

  • CLI commands like distant manager select will now output errors in a JSON format when configured to communicate using JSON
  • distant-ssh2 no longer caches the remote family globally, but instead caches it per Ssh instance

Removed

  • Cmd::program and Cmd::arguments functions as they were misleading (didn't do what distant-local or distant-ssh2 do)
  • Removed Capability and Capabilities from protocol and manager

0.20.0-alpha.12

Changed

  • Minimum Rust version is now 1.70.0 due to bump in grep-cli minimum requirement. This technically applied to v0.20.0-alpha.11, but wasn't caught until the dependency updated

Fixed

  • distant --help will now return exit code of 0
  • distant --version will now return exit code of 0

0.20.0-alpha.11

Added

  • CLI now supports -c <STR> and --cmd <STR> to use a given string as the command as an alternative to -- <CMD> <ARG> <ARG>
  • Add build for FreeBSD

Changed

  • Cli no longer uses -c as shorthand for specifying a config file
  • --file option for generating completion has been renamed to --output
  • CLI command to generate config files now defaults to printing to stdout with --output providing the option to write to a file
  • Artifacts built now use format of distant-<TRIPLE>

0.20.0-alpha.10

Added

  • use_hidden, use_ignore_files, use_parent_ignore_files, use_git_ignore, use_global_git_ignore, and use_git_exclude as new options for searching

Changed

  • Searching now disables all standard filters by default with re-introducing the ability to set the filters by individual options

Fixed

  • Failing to start a search will no longer cause the search task to exit when using the local server, which would result in no more searches being able to be executed

0.20.0-alpha.9

Added

  • Request and Response types from distant-net now support an optional Header to send miscellaneous information

Changed

  • Change structure now provides a single path instead of paths with the distant-local implementation sending a separate Changed event per path
  • ChangeDetails now includes a renamed field to capture the new path name when known
  • DistantApi now handles batch requests in parallel, returning the results in order. To achieve the previous sequential processing of batch requests, the header value sequence needs to be set to true
  • Rename GenericServerRef to ServerRef and remove ServerRef trait, refactoring TcpServerRef, UnixSocketServerRef, and WindowsPipeServerRef to use the struct instead of Box<dyn ServerRef>
  • Update Reply trait and associated implementations to be non-blocking & synchronous as opposed to asynchronous to avoid deadlocks and also be more performant

Fixed

  • Username and password now support full character sets outside of @ for passwords and : and @ for usernames

0.20.0-alpha.8

Added

  • distant-local now has two features: macos-fsevent and macos-kqueue. These are used to indicate what kind of file watching to support (for MacOS). The default is macos-fsevent.
  • [server.watch] configuration is now available with the following settings:
    • native = <bool> to specify whether to use native watching or polling (default true)
    • poll_interval = <secs> to specify seconds to wait between polling attempts (only for polling watcher)
    • compare_contents = <bool> to specify how polling watcher will evaluate a file change (default false)
    • debounce_timeout = <secs> to specify how long to wait before sending a change notification (will aggregate and merge changes)
    • debounce_tick_rate = <secs> to specify how long to wait between event aggregation loops
  • distant-protocol response for a change now supports these additional fields:
    • timestamp (serialized as ts) to communicate the seconds since unix epoch when the event was received
    • details containing attributes (clarify changes on attribute kind) and extra (to convey arbitrary platform-specific extra information)

Changed

  • Bump minimum Rust version to 1.68.0

Removed

  • crossbeam-channel dependency removed from notify by disabling its feature in order to avoid a tokio::spawn issue (notify-rs/notify#380)

Fixed

  • usernames with - (hyphen) we're rejected as invalid

0.20.0-alpha.7

Added

  • New SetPermissions enum variant on protocol request
  • New set_permissions method available DistantApi and implemented by local server (ssh unavailable due to wezterm/wezterm#3784)
  • Implementation of DistantChannelExt::set_permissions
  • distant version to display information about connected server
  • distant manager service install now accepts additional arguments to provide the manager on startup

Changed

  • Moved distant_net::common::transport::framed::codec::encryption::SecretKey and similar to distant_net::common::SecretKey
  • Search matches reported with match key are now inlined as either a byte array or a string and no longer an object with a type and value field
  • Unset options and values are not now returned in JSON serialization versus the explicit null value provided
  • Capabilities message type has been changed to Version with new struct to report the version information that includes a server version string, protocol version tuple, and capabilities
  • distant_core::api::local moved to distant_local

Removed

  • distant capabilities has been removed in favor of distant version

0.20.0-alpha.6

Changed

  • Renamed distant_core::data to distant_core::protocol
  • CLI --lsp now accepts an optional scheme to be used instead of distant://, which is the default
  • RemoteLspProcess now takes a second argument, scheme, which dictates whether to translate distant:// or something else

0.20.0-alpha.5

Added

  • CLI now offers the following new subcommands
    • distant fs copy is a refactoring of distant client action copy
    • distant fs exists is a refactoring of distant client action exists

  • Ability to generate default configuration using distant generate config /path/to/config.toml
  • --current-dir option for distant client shell and distant client lsp

Changed

  • Updated a variety of dependencies to latest versions

0.20.0-alpha.3 - 2022-11-27

Added

  • Frame::empty method as convenience for Frame::new(&[])
  • ClientConfig to support ReconnectStrategy and a duration serving as the maximum time to wait between server activity before attempting to reconnect from the client
  • Server sends empty frames periodically to act as heartbeats to let the client know if the connection is still established
  • Client now tracks length of time since last server activity and will attempt a reconnect if no activity beyond that point

Added

  • New ConnectionState and ConnectionWatcher to support watching changes to the client connection, supporting clone_connection_watcher and on_connection_change methods for the client

Changed

  • Server will now drop the connection if it receives an error (other than WouldBlock) while trying to read from the transport, rather than just logging the error, regardless of whether the error is resumable

0.20.0-alpha.1 - 2022-11-19

NOTE: This is incomplete as v0.20.0 is a near-complete rewrite internally.

Added

  • New contains and or types for SearchQueryCondition

Changed

  • SearchQueryCondition now escapes regex for all types except regex
  • Removed min_depth option from search
  • Updated search to properly use binary detection, filter out common ignore file patterns, and execute in parallel via the ignore crate and num_cpus crate to calculate thread count

Fixed

  • Resolution of BindAddress now properly handles hostnames ranging from localhost to example.com
  • Parsing of BindAddress no longer causes a stack overflow

0.19.0 - 2022-08-30

Added

  • SystemInfo via ssh backend now detects and reports username and shell
  • SystemInfo via ssh backend now reports os when windows detected
  • Capabilities request/response for server and manager that report back the capabilities (and descriptions) supported by the server or manager
  • Search and CancelSearch request/response for server that performs a search using grep crate against paths or file contents, returning results back as a stream
    • New Searcher available as part of distant client interface to support performing a search and getting back results
    • Updated DistantChannelExt to support creating a Searcher and canceling an ongoing search query
    • distant client action search now supported, waiting for results and printing them out

Changed

  • SystemInfo data type now includes two additional fields: username and shell. The username field represents the name of the user running the server process. The shell field points to the default shell associated with the user running the server process

Fixed

  • distant client shell will now use the default shell from system info, or choose between /bin/sh and cmd.exe as the default shell based on the family returned by a system info request
  • distant client shell properly terminates master pty when the shell exits, resolving the hanging that occurred for Windows cmd.exe and powershell.exe upon exit
  • ssh launch with login shell now only uses sh when remote family is unix
  • ssh backend implementation of copy now works more widely across windows systems by switching to powershell.exe to perform copy

0.18.0 - 2022-08-18

Changed

  • shutdown-after replaced with shutdown that supports three options:
    1. never - server will never shutdown automatically
    2. after=N - server will shutdown after N seconds
    3. lonely=N - server will shutdown N seconds after no connections

0.17.6 - 2022-08-18

Fixed

  • shutdown-after cli parameter and config option now properly shuts down server after N seconds with no connections

0.17.5 - 2022-08-18

Fixed

  • Handle RecommendedWatcher failing with an unsupported OS function on M1 Mac architecture running a Linux container via Docker (notify #423)

0.17.4 - 2022-08-18

Fixed

  • Parsing of a host for Destination now correctly handles IPv6 addresses such that ::1 and [::1]:12345 are captured into host and port
  • Displaying of Distant and DistantSingleKeyCredentials now properly wrap IPv6 addresses in square brackets when a port is available

0.17.3 - 2022-08-18

Added

Changed

  • Destination now has direct fields for scheme, username, password, host, and port that are populated from parsing
  • Destination no longer wraps uriparse::URI and all references to implementing/wrapping have been removed

Fixed

  • ssh option to specify external binary not working on launch due to the key being mis-labeled as ssh.bind instead of ssh.bin
  • All ssh settings were not being applied with manager handlers due to some key checks being incorrect (e.g. backend instead of ssh.backend). This has now been corrected and settings now properly get applied

Removed

  • The ssh settings of ssh.user and ssh.port were unused as these were now being taking from the destination ssh://[username:]host[:port], so they have now been removed to avoid confusion
  • Remove uriparse dependency

0.17.2 - 2022-08-16

Added

  • replace_scheme method to Destination

Fixed

  • DistantManagerRouter no longer silently fails when distant.args is provided that includes double quotes within it

Changed

  • Map implementation of Display now escapes \ and "
  • Map implementation of FromStr now handles escaped \ and "
  • Split fallback_scheme for DistantManagerConfig into launch_fallback_scheme (defaulting to ssh) and connect_fallback_scheme (defaulting to distant); this means that subsequent use of distant client launch [user@]host[:port] will now default to ssh instead of failing due to lack of distant launch handler
  • Expose windows-pipe and unix-socket config and cli options regardless of platform (so they can be provided without worrying about which OS)
  • Lock --access to distant manager listen as a cli parameter and move it out of [network] config to be tied to manager config only

0.17.1 - 2022-08-16

Added

  • New format option available for client select
    • Choices are provided via {"type": "select", "choices": ["...", ...], "current": 0}
    • Selection is specified via {"type": "selected", "choice": 0}

Fixed

  • distant client launch using --format json now properly prints out id in JSON format ({"type": "launched", "id": "..."})
  • distant client connect using --format json now properly prints out id in JSON format ({"type": "connected", "id": "..."})

0.17.0 - 2022-08-09

Added

  • distant manager subcommand
    • distant manager service subcommand contains functionality to install, start, stop, and uninstall the manager as a service on various operating systems

    • distant manager list will print information about all connections
  • distant generate subcommand
    • distant generate schema will produce JSON schema for server request/response
    • distant generate completion will produce completion file for a specific shell

Changed

Removed

  • Networking directly from distant client to distant server. All connections are now facilitated by the manager interface with client -> manager -> server
  • Environment variable output as part of launch is now gone as the connection is now being managed, so there is no need to export session information

0.16.4 - 2022-06-01

Added

Removed

  • Github actions no longer use paths-filter so every PR & commit will test everything
  • distant-lua and distant-lua-test no longer exist as we are focusing solely on the JSON API for integration into distant

0.15.1 - 2021-11-15

Added

  • --key-from-stdin option to listen cli command to read key from stdin instead of generating
  • More logging to distant and ssh handler proc run methods
