c++ - spidermonkey 1.8.5 crashes in debug mode -


i using spidermonkey 1.8.5 in application. application crashes when use debug js library. building library following options: --enable-debug --disable-optimize --enable-threadsafe

crash pointing here: assertion failure: (cx)->thread->data.requestdepth || (cx)->thread == (cx)->runtime->gcthread, @ ../../src/jsapi.cpp

here sample program

/* include jsapi header file access spidermonkey. */ #include "jsapi.h"    /* class of global object. */ static jsclass global_class = {     "global", jsclass_global_flags,     js_propertystub, js_propertystub, js_propertystub, js_strictpropertystub,     js_enumeratestub, js_resolvestub, js_convertstub, js_finalizestub,     jsclass_no_optional_members };  /* error reporter callback. */ void reporterror(jscontext *cx, const char *message, jserrorreport *report) {     fprintf(stderr, "%s:%u:%s\n",             report->filename ? report->filename : "<no filename=\"filename\">",             (unsigned int) report->lineno,             message); }  int main(int argc, const char *argv[]) {     /* jsapi variables. */     jsruntime *rt;     jscontext *cx;     jsobject  *global;     printf("started\n");     /* create js runtime. need @ least 1 runtime per process. */     rt = js_newruntime(8 * 1024 * 1024);      if (rt == null)         return 1;      /*      * create context. need context per thread.      * note program not multi-threaded.      */     cx = js_newcontext(rt, 8192);     if (cx == null)         return 1;      js_seterrorreporter(cx, reporterror);      /*      * create global object in new compartment.      * need global object per context.      */     global = js_newcompartmentandglobalobject(cx, &global_class, null);     if (global == null)         return 1;      /*      * populate global object standard javascript      * function , object classes, such object, array, date.      */     if (!js_initstandardclasses(cx, global))         return 1;      /* application code here. may include jsapi calls      * create own custom javascript objects , run scripts.      *      * following example code creates literal javascript script,      * evaluates it, , prints result stdout.      *      * errors conventionally saved in jsbool variable named ok.      */     char *script = "'hello ' + 'world!'";     jsval rval;     jsstring *str;     jsbool ok;     const char *filename = "noname";     uintn lineno = 0;      ok = js_evaluatescript(cx, global, script, strlen(script),                            filename, lineno, &rval);     if (rval == null | rval == js_false)         return 1;      str = js_valuetostring(cx, rval);     printf("%s\n", js_encodestring(cx, str));      /* end of application code */      /* clean things , shut down spidermonkey. */     js_destroycontext(cx);     js_destroyruntime(rt);     js_shutdown();     return 0; }

if building in release mode program works fine. problem debug mode. missing here?

insert js_beginrequest(cx); before js_newcompartmentandglobalobject call.

insert js_endrequest(cx); before call js_destroycontext.

most jsapi functions require request. (i'm not sure why. original reason threads had multithreading, each jsruntime single-threaded now.)

the debug build of spidermonkey includes assertions check api usage in ways release mode can't. see debug-only assertions again. recommend developing against debug build, because assertions indicate real problems.

the next spidermonkey release coming soon: https://bugzilla.mozilla.org/show_bug.cgi?id=735599#c54

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
