Synchronet now requires the libarchive development package (e.g. libarchive-dev on Debian-based Linux distros, libarchive.org for more info) to build successfully.

    Invoking a JavaScripot global hot key event handler (e.g. nodelist.js) *while* · c912ee30
    rswindell authored
    running a JavaScript module would crash (e.g. segfault) sbbs:
    Create and use a separate JS runtime, context, and global object/scope for
    global hotkey events. This means that the hotkey won't benefit from any
    previously loaded/required scripts, possibly effecting the performance of the
    first invocation of the hotkey handler. Subsequent JS hotkey events will reuse
    the same runtime/context/global, so they'll execute fast(er).
    
    One questionalbe change to js_execfile():
    With the JS_GC (garbage collection) call *before* the JS_ENDREQUEST() call, the
    process would crash in libmozjs. Moving the JS_GC() call to *after* the
    JS_ENDREQUEST() resolved this issue and I'm not clear why. This 'js_cx'
    parameter here is not always sbbs_t::js_cx. When called to handle a JS hotkey
    event, it's sbbs_t::js_hotkey_cx, so it shouldn't interfere with the
    sbs_t::js_cx being used by the currently executing JS module (shell or door).
