|
|
|
|
|
|
|
|
* Improve Ctrl-C handling with programs that use unprocessed input. (e.g.
|
|
|

2017-04-23 05:09:36 +00:00
|
|
|
* winpty now synthesizes a `WINDOW_BUFFER_SIZE_EVENT` event after resizing
|
|
|
|
|
the console to better propagate window size changes to console programs.
|
|
|
|
|
In particular, this affects WSL and Cygwin.

# Version 0.4.2 (2017-01-18)
|
Pass certain keys to the console using windows messages.
If the terminal is placed in an alternate mode using DECCKM, then we
need to generate different input escape sequences for WSL (and other
programs using ENABLE_VIRTUAL_TERMINAL_INPUT). AFAIK, there is no way
for winpty to detect whether an alternate mode is enabled, but it only
seems to affect a small number of keys, so send those keys as window
messages.
We don't send *all* keys as window messages, because the console may try
to interpret some of them. It doesn't interpret the arrow keys and
Home/End, AFAICT, and those seem to be the only keys affected by DECCKM.
(The console's line-input mode *does* care about these navigation keys,
but in that case, WriteConsoleInput and window messages work equally well.)
DECCKM only seems to affect the keys when there is no modifier key.
I believe that by using SendMessage, winpty-agent will block until the
keys are appended to the console input buffer. I'm not sure how to verify
it. If this *weren't* the case, there could be a danger of key input
being transposed. It seems unlikely to be an issue.

has no effect. AFAIK, the mechanism was never used publicly.

# Version 0.4.0 (2016-06-28)
|
Replace the libwinpty API.
The new API improves upon the old API in a number of ways:
* The old API provided a single data pipe for input and output, and it
provided the pipe in the form of a HANDLE opened with
FILE_FLAG_OVERLAPPED. Using a bare HANDLE is difficult in higher-level
languages, and overlapped/asynchronous I/O is hard to get right.
winpty_close closed the data pipe, which also didn't help things, though
I think the handle could have been duplicated.
Using a single handle for input and output complicates shutdown. When
the child process exits, the agent scrapes the final output, then closes
the data pipe once its written. It's possible that a winpty client will
first detect the closed pipe when it's writing *input* rather than
reading output, which seems wrong. (On the other hand, the agent
doesn't implement "backpressure" for either input or output (yet), and
if it did, it's possible that post-exit shutdown should interrupt a
blocked write into the console input queue. I need to think about it
more.)
The new API splits the data pipe into CONIN and CONOUT pipes, which are
accessed by filename. After `winpty_open` returns, the client queries
pipe names using `winpty_conin_name` and `winpty_conout_name`, then
opens them using any mechanism, low-level or high-level, blocking or
overlapped.
* The old libwinpty handled errors by killing the process. The new
libwinpty uses C++ exceptions internally and translates exceptions at
API boundaries using:
- a boolean error result (e.g. BOOL, NULL-vs-non-NULL)
- a potentially heap-allocated winpty_error_t object returned via an
optional winpty_error_ptr_t parameter. That parameter can be NULL.
If it isn't, then an error code and message can be queried from the
error object. The winpty_error_t object must be freed with
winpty_error_free.
* winpty_start_process is renamed to winpty_spawn. winpty_open and
winpty_spawn accept a "config" object which holds parameters. New
configuration options can be added without disturbing the source or
binary API.
* The winpty_get_exit_code and winpty_get_process_id APIs are removed.
The winpty_spawn function has an out parameter providing the child's
process and thread HANDLEs (duplicated from the agent via
DuplicateHandle). The winpty client can call GetExitCodeProcess and
GetProcessId (as well as the WaitForXXX APIs to wait for child exit).

User-visible changes:
|
|
|
|
|
|
|
|
|
|
* winpty now automatically puts the terminal into mouse mode when it detects
|
|
|
|
|
that the console has left QuickEdit mode. The `--mouse` option still forces
|
|
|
|
|
the terminal into mouse mode. In principle, an option could be added to
|
|
|
|
|
suppress terminal mode, but hopefully it won't be necessary. There is a
|
|
|
|
|
script in the `misc` subdirectory, `misc/ConinMode.ps1`, that can change
|
|
|
|
|
the QuickEdit mode from the command-line.
|
Pass keyboard escapes to the WSL bash.exe wrapper
The wrapper enables the undocumented mode flag 0x200 on the CONIN handle,
which directs the Windows console to replace most KeyDown input records
with sequences of plain bytes, which are escape sequences for control and
navigation keys.
This particular solution reencodes escape sequences and looks roughly
similar to what the Windows console generates, with a few differences:
* For Alt-Backspace, winpty generates ^[ ^?, whereras Windows generates
^[ ^H.
* For Shift/Alt/Ctrl-modified sequences, winpty encodes the mask of
modifiers into the escape sequences.
* winpty generates ^[ Z for Shift-Tab, rather than ^I.
* winpty generates ^[ E for the NumPad "clear/5" key, rather than nothing.
I'm still not sure winpty *ought* to do this reencoding. I don't think
generating KeyUp events is necessary. In principle, it might be
needed/useful for dealing with various terminals. WSL bash.exe always
sets TERM to xterm, and even if changing it is correct w.r.t. input, it's
not necessarily correct for output -- the Windows console system is
expecting to see TERM=xterm output, which it uses to updates it screen
buffer. (I'm not sure that matters, much, though. I suppose
TERM=xterm-256color could be a problem?)

and includes a random component in the name. winpty secures pipes with a
|
|
|
|
|
DACL that prevents arbitrary users from connecting to its pipes. winpty now
|
|
|
|
|
passes `PIPE_REJECT_REMOTE_CLIENTS` on Vista and up, and it verifies that
|
2016-04-04 11:41:42 +00:00
|
|
|
the pipe client PID is correct, again on Vista and up. When connecting to a
|
|
|
|
|
named pipe, winpty uses the `SECURITY_IDENTIFICATION` flag to restrict
|
|
|
|
|
impersonation. Previous versions *should* still be secure.
|
2016-03-30 07:59:45 +00:00
|
|
|
* `winpty-debugserver.exe` now has an `--everyone` flag that allows capturing
|
|
|
|
|
debug output from other users.
|
2016-04-04 11:41:42 +00:00
|
|
|
* The code now compiles cleanly with MSVC's "Security Development Lifecycle"
|
|
|
|
|
(`/SDL`) checks enabled.

Minor bug fixes and enhancements:
|
|
|
|
|
|
|
|
|
|
* Fix a bug that generated spurious mouse input records when an incomplete
|
|
|
|
|
mouse escape sequence was seen.
|
|
|
|
|
* Fix a buffer overflow bug in `winpty-debugserver.exe` affecting messages of
|
|
|
|
|
exactly 4096 bytes.
|
|
|
|
|
* For MSVC builds, add a `src/configurations.gypi` file that can be included
|
|
|
|
|
on the gyp command-line to enable 32-bit and 64-bit builds.
|
|
|
|
|
* `winpty-agent --show-input` mode: Flush stdout after each line.
|
|
|
|
|
* Makefile builds: generate a `build/winpty.lib` import library to accompany
|
|
|
|
|
`build/winpty.dll`.

# Version 0.2.1 (2015-12-19)
|
2015-11-29 09:50:06 +00:00
|
|
|
|
|
|
|
|
* The main project source was moved into a `src` directory for better code
|
|
|
|
|
organization and to fix
|
|
|
|
|
[#51](https://github.com/rprichard/winpty/issues/51).
|
2015-12-04 05:41:11 +00:00
|
|
|
* winpty recognizes many more escape sequences, including:
|
|
|
|
|
* putty/rxvt's F1-F4 keys
|
|
|
|
|
[#40](https://github.com/rprichard/winpty/issues/40)
|
|
|
|
|
* the Linux virtual console's F1-F5 keys
|
|
|
|
|
* the "application numpad" keys (e.g. enabled with DECPAM)
|
2015-12-01 11:03:58 +00:00
|
|
|
* Fixed handling of Shift-Alt-O and Alt-[.
|
2015-12-16 12:30:58 +00:00
|
|
|
* Added support for mouse input. The UNIX adapter has a `--mouse` argument
|
2015-12-16 10:21:22 +00:00
|
|
|
that puts the terminal into mouse mode, but the agent recognizes mouse
|
2015-12-20 08:02:45 +00:00
|
|
|
input even without the argument. The agent recognizes double-clicks using
|
|
|
|
|
Windows' double-click interval setting (i.e. GetDoubleClickTime).

|
|
|
Changes to debugging interfaces:
|
|
|
|
|
|
|
|
|
|
* The `WINPTY_DEBUG` variable is now a comma-separated list. The old
|
|
|
|
|
behavior (i.e. tracing) is enabled with `WINPTY_DEBUG=trace`.
|
2015-12-16 12:30:58 +00:00
|
|
|
* The UNIX adapter program now has a `--showkey` argument that dumps input
|
|
|
|
|
bytes.
|
|
|
|
|
* The `winpty-agent.exe` program has a `--show-input` argument that dumps
|
|
|
|
|
`INPUT_RECORD` records. (It omits mouse events unless `--with-mouse` is
|
|
|
|
|
also specified.) The agent also responds to `WINPTY_DEBUG=trace,input`,
|
|
|
|
|
which logs input bytes and synthesized console events, and it responds to
|
|
|
|
|
`WINPTY_DEBUG=trace,dump_input_map`, which dumps the internal table of
|
|
|
|
|
escape sequences.

# Version 0.2.0 (2015-11-13)
|
|
|
|
|
|
|
|
|
|
No changes to the API, but many small changes to the implementation. The big
|
|
|
|
|
changes include:
|
|
|
|
|
|
|
|
|
|
* Support for 64-bit Cygwin and MSYS2
|
|
|
|
|
* Support for Windows 10
|
|
|
|
|
* Better Unicode support (especially East Asian languages)
|
|
|
|
|
|
|
|
|
|
Details:
|
|
|
|
|
|
|
|
|
|
* The `configure` script recognizes 64-bit Cygwin and MSYS2 environments and
|
|
|
|
|
selects the appropriate compiler.
|
|
|
|
|
* winpty works much better with the upgraded console in Windows 10. The
|
|
|
|
|
`conhost.exe` hang can still occur, but only with certain programs, and
|
|
|
|
|
is much less likely to occur. With the new console, use Mark instead of
|
|
|
|
|
SelectAll, for better performance.
|

|
|
|
|
[#30](https://github.com/rprichard/winpty/issues/30)
|
|
|
|
|
[#53](https://github.com/rprichard/winpty/issues/53)
|
|
|
|
|
* The UNIX adapter now calls `setlocale(LC_ALL, "")` to set the locale.
|
|
|
|
|
* Improved Unicode support. When a console is started with an East Asian code
|
|
|
|
|
page, winpty now chooses an East Asian font rather than Consolas / Lucida
|
|
|
|
|
Console. Selecting the right font helps synchronize character widths
|
|
|
|
|
between the console and terminal. (It's not perfect, though.)
|
|
|
|
|
[#41](https://github.com/rprichard/winpty/issues/41)
|
|
|
|
|
* winpty now more-or-less works with programs that change the screen buffer
|
|
|
|
|
or resize the original screen buffer. If the screen buffer height changes,
|
|
|
|
|
winpty switches to a "direct mode", where it makes no effort to track
|
|
|
|
|
scrolling. In direct mode, it merely syncs snapshots of the console to the
|
|
|
|
|
terminal. Caveats:
|
|
|
|
|
* Changing the screen buffer (i.e. `SetConsoleActiveScreenBuffer`)
|
|
|
|
|
breaks winpty on Windows 7. This problem can eventually be mitigated,
|
|
|
|
|
but never completely fixed, due to Windows 7 bugginess.
|
|
|
|
|
* Resizing the original screen buffer can hang `conhost.exe` on Windows 10.
|
|
|
|
|
Enabling the legacy console is a workaround.
|
|
|
|
|
* If a program changes the screen buffer and then exits, relying on the OS
|
|
|
|
|
to restore the original screen buffer, that restoration probably will not
|
|
|
|
|
happen with winpty. winpty's behavior can probably be improved here.
|
|
|
|
|
* Improved color handling:
|
|
|
|
|
* DkGray-on-Black text was previously hiddenly completely. Now it is
|
|
|
|
|
output as DkGray, with a fallback to LtGray on terminals that don't
|
|
|
|
|
recognize the intense colors.
|
|
|
|
|
[#39](https://github.com/rprichard/winpty/issues/39).
|
|
|
|
|
* The console is always initialized to LtGray-on-Black, regardless of the
|
|
|
|
|
user setting, which matches the console color heuristic, which translates
|
|
|
|
|
LtGray-on-Black to "reset SGR parameters."
|
|
|
|
|
* Shift-Tab is recognized correctly now.
|
|
|
|
|
[#19](https://github.com/rprichard/winpty/issues/19)
|
|
|
|
|
* Add a `--version` argument to `winpty-agent.exe` and the UNIX adapter. The
|
|
|
|
|
argument reports the nominal version (i.e. the `VERSION.txt`) file, with a
|
|
|
|
|
"VERSION_SUFFIX" appended (defaulted to `-dev`), and a git commit hash, if
|
|
|
|
|
the `git` command successfully reports a hash during the build. The `git`
|
|
|
|
|
command is invoked by either `make` or `gyp`.
|
|
|
|
|
* The agent now combines `ReadConsoleOutputW` calls when it polls the console
|
|
|
|
|
buffer for changes, which may slightly reduce its CPU overhead.
|
|
|
|
|
[#44](https://github.com/rprichard/winpty/issues/44).
|
|
|
|
|
* A `gyp` file is added to help compile with MSVC.
|
|
|
|
|
* The code can now be compiled as C++11 code, though it isn't by default.
|
|
|
|
|
[bde8922e08](https://github.com/rprichard/winpty/commit/bde8922e08c3638e01ecc7b581b676c314163e3c)
|
|
|
|
|
* If winpty can't create a new window station, it charges ahead rather than
|
|
|
|
|
aborting. This situation might happen if winpty were started from an SSH
|
|
|
|
|
session.
|
|
|
|
|
* Debugging improvements:
|
|
|
|
|
* `WINPTYDBG` is renamed to `WINPTY_DEBUG`, and a new `WINPTY_SHOW_CONSOLE`
|
|
|
|
|
variable keeps the underlying console visible.
|
|
|
|
|
* A `winpty-debugserver.exe` program is built and shipped by default. It
|
|
|
|
|
collects the trace output enabled with `WINPTY_DEBUG`.
|
|
|
|
|
* The `Makefile` build of winpty now compiles `winpty-agent.exe` and
|
|
|
|
|
`winpty.dll` with -O2.
