XMLHttpRequest and 0x80004005 (NS_ERROR_FAILURE) error
Posted by mde 16 days ago

I would have thought they'd have fixed this bug in Firefox by now, but I just ran into it again. I can remember bumping my head on this about a year and a half ago.

I have a pop-up window that invokes an XHR request to re-render its opener window (the window that spawns the pop-up), with a call like opener.doUpdateWithXHR() or whatever. It's supposed to pull down some content from the server and repaint the main window.

This works fine with the initial call, but if you close the pop-up window, all subsequent attempts to make requests with the same XHR object result in this little gem of an error: "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIXMLHttpRequest.open]" Has a sort of sparse elegance to it, I think.

This guy reports the same problem, but with calling XHR in the parent of an iframe that he removes. He points to a Mozilla bug for the issue, opened in ... July of 2004.

The workaround, of course, is to call your function in the opener/parent window through setTimeout, to force it to execute in the context of that window. Make a function in your main window like this:

function doUpdateWithXHRFromPopup() {
    setTimeout(doUpdateWithXHR, 0);
}
And call that function from your popup/iframe instead of referencing doUpdateFromXHR directly. (Another less-optimal workaround would be just to create a brand-new XHR object for the request.)

I wonder if or when they ever plan on fixing this. They still have it flagged as 'New' in Bugzilla. I know it's an Ajaxey, Web 2.0 world and all, but it's not like pop-ups/iframes and XHR are some sort of matter and anti-matter combination. You ought to be able to use the old stuff and the new stuff together without them going kerblooey.

 

 

1. Download Apache 2 builded with SSL

    http://hunter.campbus.com/

2. Generate SSL private key, csr, and certificate

    - generate private key ( with password ): openssl genrsa -des3 -out privkey.pem 2048
    - generate private key ( without password ): openssl genrsa -out privkey.pem 2048
    - generate csr: openssl req -new -key privkey.pem -out cert.csr
    - generate self-signed certificate: openssl req -new -x509 -key privkey.pem -out cacert.pem -days 1095
    put these files in conf\ssl.crt\
    http://www.openssl.org/docs/HOWTO/

3. Modify httpd.conf
    - unremark LoadModule ssl_module modules/mod_ssl.so
    - add: Listen 443

    - add SSL setting

             SSLCertificateFile conf/ssl.crt/cacert.pem
             SSLCertificateKeyFile conf/ssl.crt/privkey.pem 

    - add Virtual Host

            <VirtualHost yourservername:443>
             SSLEngine On
             ServerAdmin webmaster@dummy-host.example.com
             DocumentRoot d:/apache/htdocs/
             ServerName yourservername

             </VirtualHost>

4. Restart your apache and try

    http://yourservername/

    https://yourservername/

Michael 終於在拿到Monza GP之後決定退休

聽到這個消息真是令我百感交集

雖然我不是標準的Tifosi，看F1也沒有多少年的時間

沒能恭逢Schumy和Senna, Mika, Villeneuve大戰的時光

但總算也經歷他在Ferrari大放異彩的日子（常常獨走在前讓人猛打哈欠）

不管喜不喜歡 Schumacher的車迷，都得承認他確實是一代車神

所有的人都以打倒他為目標，都以跑在他前面為榮

雖然這兩年遭受到阿龍嫂跟雷諾的挑戰

可是37歲的他還是讓人感受到不放棄的奮戰精神

 

今天聽到他緩緩說出retirement時，令我不禁泛紅了眼眶

又一個生命中的偶像離開了他的舞台（明明還能跑啊，幹嘛要走 >< ）

真的很慶幸自己能夠經歷Michael Schumacher的年代，見證了有史以來最偉大車神的傳奇

沒有了Schumy，以後再也聽不到德國+義大利的國歌組合了（至少幾年內不會吧 ... ）

F1還是會繼續，Kimi、阿龍嫂、鈕釦還是會帶來一場場精彩的比賽

但我知道，這樣的F1已經不會再是我記憶中的那個F1了

 

PS.

這真是一個令人百感交集的週末（簡直快要爆肝）

先是小郭、小姜、小王先後拿到勝投，美少女小莎拿到第二個大滿貫

Schumy和Ferrari又拿下Monza GP，本來真是一個完美的Ending

沒想到出現這個消息 ...

一個個偶像接連著隕落 .... 意味著我真的年齡大到一個地步了嗎 .... 唉 .......
