# Next Version
|
|
|
|
The winpty library has a new API that should be easier for embedding.
|
|
|
|
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.
|
|
|
|
Bug fixes:
|
|
|
|
* By default, `winpty.dll` avoids calling `SetProcessWindowStation` within
|
|
the calling process.
|
|
[#58](https://github.com/rprichard/winpty/issues/58)
|
|
* Fixed an uninitialized memory bug that could have crashed winpty.
|
|
[#80](https://github.com/rprichard/winpty/issues/80)
|
|
* winpty now works better with very large and very small terminal windows.
|
|
It resizes the console font according to the number of columns.
|

|
|
# Version 0.3.0 (2016-05-20)
|
|
|
|
User-visible changes:
|
|
|
|
* The UNIX adapter is renamed from `console.exe` to `winpty.exe` to be
|
|
consistent with MSYS2. The name `winpty.exe` is less likely to conflict
|
|
with another program and is easier to search for online (e.g. for someone
|
|
unfamiliar with winpty).
|
|
* The UNIX adapter now clears the `TERM` variable.
|
|
[#43](https://github.com/rprichard/winpty/issues/43)
|
|
* An escape character appearing in a console screen buffer cell is converted
|
|
to a '?'.
|
|
[#47](https://github.com/rprichard/winpty/issues/47)
|
|
|
|
Bug fixes:
|
|
|
|
* A major bug affecting XP users was fixed.
|
|
[#67](https://github.com/rprichard/winpty/issues/67)
|
|
* Fixed an incompatibility with ConEmu where winpty hung if ConEmu's
|
|
"Process 'start'" feature was enabled.
|
|
[#70](https://github.com/rprichard/winpty/issues/70)
|
|
* Fixed a bug where `cmd.exe` sometimes printed the message,
|
|
`Not enough storage is available to process this command.`.
|
|
[#74](https://github.com/rprichard/winpty/issues/74)
|
|
|
|
Many changes internally:
|
|
|
|
* The codebase is switched from C++03 to C++11 and uses exceptions internally.
|
|
No exceptions are thrown across the C APIs defined in `winpty.h`.
|
|
* This version drops support for the original MinGW compiler packaged with
|
|
Cygwin (`i686-pc-mingw32-g++`). The MinGW-w64 compiler is still supported,
|
|
as is the MinGW distributed at mingw.org. Compiling with MSVC now requires
|
|
MSVC 2013 or newer. Windows XP is still supported.
|
|
[ec3eae8df5](https://github.com/rprichard/winpty/commit/ec3eae8df5bbbb36d7628d168b0815638d122f37)
|
|
* Pipe security is improved. winpty works harder to produce unique pipe names
|
|
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
|
|
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.
|
|
* `winpty-debugserver.exe` now has an `--everyone` flag that allows capturing
|
|
debug output from other users.
|
|
* The code now compiles cleanly with MSVC's "Security Development Lifecycle"
|
|
(`/SDL`) checks enabled.
|
|
|
|
# Version 0.2.2 (2016-02-25)
|
|
|
|
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)
|
|
|
|
* 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).
|
|
* 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)
|
|
* Fixed handling of Shift-Alt-O and Alt-[.
|
|
* Added support for mouse input. The UNIX adapter has a `--mouse` argument
|
|
that puts the terminal into mouse mode, but the agent recognizes mouse
|
|
input even without the argument. The agent recognizes double-clicks using
|
|
Windows' double-click interval setting (i.e. GetDoubleClickTime).
|
|
[#57](https://github.com/rprichard/winpty/issues/57)
|
|
|
|
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`.
|
|
* 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.
|
|
[#31](https://github.com/rprichard/winpty/issues/31)
|
|
[#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.
