在其中一个线程上调用!DumpStack,我得到:

我想知道是否有其他人在这个问题上绊倒并且想看看你是如何解决它的.
最好的想法是为ElastiCache(像Twitter代理)编写代理,但这是一项艰巨的任务.
提前致谢.
我只是尝试了安装颤振,因为我已经安装了android工作室和安装了android sdk,我只是跟着安装了颤动.这是我的问题:我跑的时候

<video class="hidden-xs hidden-sm hidden-md hidden-custom videosize embed-responsive-item" autoplay="autoplay" loop="loop">
<source src="~/Videos/myvideo.mp4" type="video/mp4" />
</video>
CSS:
.videosize {
position:absolute;
z-index:-1;

使用上面的代码,它完全符合1680 x 1050的屏幕分辨率,但是对于其他分辨率,它占据了高度的100%然后宽度调整,在两侧留下白色空间.
任何的想法 ？谢谢.
当我在Sinatra/ruby应用程序中使用ALLIANCE FEED时,我得到了一个

用例是,我的全局错误处理程序alert box在屏幕顶部显示一个咆哮.但是我弹出了几个模态,我在那里显式处理错误,在模态本身显示错误信息.因此,基本上,这个模态控制器应该将被拒绝的承诺标记为"已处理".但由于拦截器似乎总是第一个运行$http error,我无法想出办法.
这是我的拦截器代码:
angular.module("globalErrors", ['angular-growl', 'ngAnimate'])
.factory("myHttpInterceptor", ['$q', '$log', '$location', '$rootScope', 'growl', 'growlMessages',
function ($q, $log, $location, $rootScope, growl, growlMessages) {
var numLoading = 0;
return {
request: function (config) {
if (config.showLoader !== false) {
numLoading++;
$rootScope.loading = true;
}
return config || $q.when(config)
},
response: function (response) {
if (response.config.showLoader !== false) {
numLoading--;
$rootScope.loading = numLoading > 0;
}
if(growlMessages.getAllMessages().length) { // clear messages on next …let distance (x:(float * float)): float =
sqrt ((fst x * fst x) + (snd x * snd x))
let getClosestPair (pairs:(float * float) list) =
let mutable closest = (0.0, 0.0)
if List.isEmpty pairs then
(infinity, infinity)
else
closest <- pairs.[0]
for i in pairs do
if (distance i) < (distance closest) then closest <- i
上面的函数通过浮点对列表.每一对都像笛卡尔平面上的坐标.该函数找到与原点最接近的一对.底部的for循环生成类型错误.
"这个表达式预计有float*float类型,但这里有类型单位"
我该如何解决这个错误？
我RecyclerView用LinearLayoutManager(Vertical不倒).当我将项目插入或移动到0位置时,会调用此方法:
private void scrollToStart() {
int firstVisiblePosition = ((LinearLayoutManager) recentList.getLayoutManager()).findFirstCompletelyVisibleItemPosition();
boolean notScrolling = recentList.getScrollState() == RecyclerView.SCROLL_STATE_IDLE;
if (firstVisiblePosition < 2 && notScrolling) {
recentList.scrollToPosition(0);
}
}
但有时它会平滑滚动到列表的末尾.
(我在Instagram等应用程序中看到过这样的行为.看起来列表滚动到顶部然后开始向相反的方向移动.)
如果我smoothScrollToPosition用simple 替换scrollToPosition它,它的行为应该如此.
如何防止此滚动？
我试图阻止Android信标库的调试,但它不起作用.
我在我的gradle中有这个:
compile 'org.altbeacon:android-beacon-library:2.3.3'
我试过了:
public BeaconManager(Context ctx, org.altbeacon.beacon.BeaconManager beaconManager) {
mContext = ctx;
this.beaconManager = beaconManager;
// this is saying deprecated
this.beaconManager.setDebug(false);
// I also tried this and the same thing
org.altbeacon.beacon.logging.LogManager.setVerboseLoggingEnabled(false);
但无论如何,我一直在获取这些日志.他们开始调试其他事情.
