NppExec plugin does not allow TCEdit.exe to close properly.

The NppExec plugin works as it should,
that is,
it allows me to run a .btm from within TCEdit.exe,
with output being displayed in the NppExec Console.

Exiting TCEdit.exe does not result in TCEdit.exe being closed.

R:\>if isapp tcedit.exe echo Yes
Yes

R:\>tcedit.exe

R:\>taskend /f tcedit*

R:\>if isapp tcedit.exe echo Yes

Attempting to launch TCEdit.exe after I have closed it,
does not launch TCEdit.exe,
as it is still in memory,
and must be ended forcefully.

Fixed in build 69. (Timing problem in NppExec's teardown; it was looking for a TCEdit window that might or might not still exist during shutdown.)

Still not working in build 69.

I should add that it is "fixed" if one does not run an NppExec script.

That is, with the NppExec plugin loaded,
exiting TCEdit.exe does not leave TCEdit.exe in memory.

If I run an NppExec script,
exit TCEdit.exe,
then TCEdit.exe remains in memory,
and I have to use Taskend /f tcedit* to remove it from memory.

Do you have an example script that reproduces the problem?

 

[Joe Caverly]

Execute any NppExec script and it causes TCEdit.exe not to exit properly.

Did you try the NppExec script that I provided in my OP?

NPP_CONSOLE 1
NPP_SAVE
set local TCCRT=C:\Program Files\JPSoft\TCC_RT_36\TCC.EXE
"$(TCCRT)" /q "$(FULL_CURRENT_PATH)

This is my work-around for now;

@SETLOCAL
@ECHO OFF

:: This works with Options -> Single Instance Enabled
iff isapp tcedit.exe then
  iff isvisible *tcedit* then
    start tcedit.exe %$
  else
    taskend /f tcedit*
    start tcedit.exe %$
  endiff
else
  start tcedit.exe %$
endiff
ENDLOCAL

Try it with build 70 (already uploaded) and let me know if it works.

TCC 36.50.70 x64 Windows 10 [Version 10.0.19045.7417]
Launch TCEdit.exe with NppExec Plugin loaded,
no NppExec Script executed,
exit TCEdit.exe

R:\>tcedit.exe r:\test.btm

R:\>if isapp tcedit.exe echo Yes

R:\>if isvisible *tcedit* echo Yes

Works as it should.

Launch TCEdit.exe with NppExec Plugin loaded,
NppExec Script executed,
exit TCEdit.exe

R:\>tcedit.exe r:\test.btm

R:\>if isapp tcedit.exe echo Yes

R:\>if isvisible *tcedit* echo Yes

Works as it should.

Thankyou Rex.

If I may,
what was causing TCEdit.exe to not close properly,
when an NppExec Script had been executed?

what was causing TCEdit.exe to not close properly,
when an NppExec Script had been executed?

NppExec creates a background thread the first time it runs a script. But NppExec does not clean up the thread when it is notified that the plugin is being shut down.

When TCEdit exited, the following sequence was executed:

1. OnClose() → NotifyShutdownWindowAlive() → beNotified(NPPN_SHUTDOWN) runs synchronously and correctly tears down NppExec's state. The BackgroundExecuteThread is still running, blocked on WaitForMultipleObjects waiting for either Stop or a new command.
2. UnloadPlugins() → m_plugins.RemoveAll() — DLL stays loaded, no FreeLibrary.
3. Window destroyed → message loop exits → ExitInstance() → CRT calls ExitProcess().
4. ExitProcess() force-terminates all threads first — including BackgroundExecuteThread,.
5. ExitProcess() then runs DLL_PROCESS_DETACH under the loader lock → globalUninitialize() → Uninit() → Stop() → m_ExecuteThreadDoneEvent.Wait(INFINITE) on an event that will never be signalled — permanent hang.
