Sometimes pressing on arrow keys prints symbols

lazycoder-ru commented 6 years ago

Versions

ConEmu build: 180626 x64 OS version: Windows 10 x32/x64 Used shell version: bash.exe from WSL(debian)

Problem description

Sometimes arrow keys(and PgUp, PgDn) do not move the cursur, but prints symbols. It appears only with ConEmu, but when I run bash.exe directly from Windows I have no problems.

Steps to reproduce

Open ConEmu;
Run task Bash(from linux subsystem);
ssh to remote server;
open text editor and move cursor by arrow keys;

Actual results

Arrow keys sometimes prints symbols(A,B,C,D).

Expected results

Arrow keys just moving cursor in editor.

Im sorry, spoke too soon :/ After further testing it seems i can reproduce it even without Clink after all, dont know how i missed it yesterday :(. Even removing the prompt changes nothing. Funny enough doing the same in the ConEmu->Debug->RealConsole window does not exhibit the behavior. Im gonna have to chalk it up to my ancient windows version...

But il dump all the relevant info below just in case.

Windows 10 1511. ConEmu 230724 (Stable). Clink v1.5.4.6f56dd.

The task: cmd -new_console:n:C:"C:\Projects\cmd_exe_16x16.ico" /k "%ConEmuBaseDir%\CmdInit_Lean.cmd"

Im sidestepping CmdInit.cmd with my own CmdInit_Lean.cmd:

prompt $E[32m$E]9;8;"USERNAME"$E\@$E]9;8;"COMPUTERNAME"$E\$S$E[92m$P$E[90m$_$$$E[m$S$E]9;12$E\
"%ConEmuBaseDir%\clink\clink_x64.exe" inject

So since im injecting clink manually, it is disabled in the ConEmu settings. And i checked that Clink is not set to autorun.

Decoded RealConsole modes from the statusbar (0x1b8,0x07):

input mode:
        ENABLE_INSERT_MODE
        ENABLE_MOUSE_INPUT
        ENABLE_WINDOW_INPUT
output mode:
        ENABLE_PROCESSED_OUTPUT
        ENABLE_WRAP_AT_EOL_OUTPUT
        ENABLE_VIRTUAL_TERMINAL_PROCESSING

They never change.

clink.log, from a fresh console running find and pressing up and enter

@grable0 Thank you for sharing the update, and that Clink isn't the cause. It might be related to your version of Windows, but it might just be a ConEmu issue.

FWIW, it looks like clink set terminal.raw_esc true will make it so even when ConEmu is in XK mode, Clink will be able to interpret the input. But you'll lose the ability for pressing Esc to clear the input line; the Esc key will instead work how it does in Unix/Linux, with the same quirks about Esc and the same situations where input can get locked up, etc. But adding [$E]9;10;0$E\](https://conemu.github.io/en/AnsiEscapeCodes.html#ConEmu_specific_OSC) to your prompt is the better option.

There is one more thing we can do, if you're interested to get to the bottom of this: We could use Time Travel Debugging to capture a log of what ConEmu does, you could send me the log, and I could analyze it to find precisely why ConEmu is activating XTerm input mode. If you're interested/willing, here is what it would involve:

I would build a copy of ConEmu so that I have matching symbols (Maximus doesn't publish symbols), and I would give you a link to my copy of ConEmu (I've already confirmed I'm able to successfully build it).
You would download my copy of ConEmu, start ConEmu, attach the Time Travel Debugging tool to the ConEmu process (not cmd) and reproduce the issue (e.g. type find and Enter and Up), then stop the TTD tool.
You would zip up the resulting conemu.run file and put it on some file share such as OneDrive, and send me a link.
I would download it, analyze it in the debugger, and report the findings.
Then we'd both delete our copies of the .run file (me, to protect your privacy; you, to reclaim disk space).

If you're up for that, send an email to the address in my github profile.

P.S. The log file you shared helped me discover a loophole in the input logging in Clink (regression introduced in v1.5.2), where it can miss logging part of the input in some cases. I've updated the logging to fix the loophole.
