    Log Message:
    Install OperationCallback for all executed JS scripts

    JS doors with the "Use Shell or New Context" option enabled in SCFG and JS modules installed a global hot key handlers would not automatically terminate when the user disconnected (and js.auto_terminate was true, the default).
    I'm not sure why the operation callback was only installed when scope==NULL
    but always installing it fixes the issue with some global hot key modules
    and JS doors becoming "zombies" when a user disconnects while running them.

    Log Message:
    Don't decrement user.xedit before calling uselect()

    This bug would leave the user's external editor setting decremented by one if they aborted (with Ctrl-C).

    Fixes issue #631

    Modified Files:

    Log Message:
    Only log a single error message when js_execfile() detects a NULL JS Context

    js_execxtrn() now returns -1 if a JS context can't be created. This eliminates redundant error messages from calling js_execfile with a NULL context.

    Log Message:
    Don't clear the console-abort flag upon return from executing a JS module

    This completes the revert of commit c22063f9 from (Jun-2-2016). The Baja
    part of that commit was reverted in commit 932fae30 (Nov-15-2016). This behavior has proven to be surprising and annoying for JS mod developers
    (e.g. the yesnobar.js and Nightfox's file searcher/scanner).

    If we still need clearing of abort status after running JS "externals",
    that should probably be done in exec_xtrn(), not here.

    Modified Files:
    src/sbbs3/exec.cpp
    Log Message:
    Save and restore the js.exec_path, exec_dir, and exec_file properties

    When invoking a nested JS script, these properties of the "js" object would
    be overwritten and not restored, as discovered/reported by Nightfox when his trivial game script would indirectly execute yesnobar.js, his subsequent use
    of js.exec_dir would point to the wrong location (the "exec" directory, parent of yesnobar.js, and not the direcctory where his game script was located).
    The exec_path and exec_file properties had the same problem as demonstrated
    by a simple test.js placed in (and executed from) a directory other than the "exec" dir:
    function f() {
    print("js.exec_path = " + js.exec_path);
    print("js.exec_dir = " + js.exec_dir);
    print("Js.exec_file = " + js.exec_file);
    }
    f();
    console.yesno("test");
    f();

    This would only trigger the problem when executed from the BBS and whebn the YesNoQuestion text.dat string invokes the "yesnobar" module via EXEC @-code and yesnobar.js exists (in exec or mods dir), superceding yesnobar.bin which does not trigger this issue (not a JavaScript mod).

    Modified Files:
    src/sbbs3/exec.cpp
    Log Message:
    Save/restore js.scope property value in sbbs_t::js_execfile()

    This solves the problem of exit() values (e.g. non-zero return codes) not getting propagated to callers when nest-called (e.g. via bbs.exec()).

    I think it was kk4qbn that pointed this out via IRC: an exit(1) call from prextrn.js did not stop the external program from running (as it should, for any non-zero exit code). This only happened when the prextrn.js called another JS script (e.g. via bbs.exec() or as was the case here, indirectly via "EXEC" @-code in the YesNoBar text.dat string (which executed yesnobar.js). This nested JS script invocation via sbbs_t::js_execfile() would clobber the stored js.scope property value (where the "exit_code" property is written).

    Script invoked in their own context (e.g. via js.exec()) wouldn't have this issue in the first place.
