Graham 9-Oct-2008 [2989] | I could store the images in the public directory ... but that's not secure. |
Terry 9-Oct-2008 [2990] | You're using the plugin? Good luck |
Graham 9-Oct-2008 [2991] | trying ... trying ... trying ... |
Henrik 9-Oct-2008 [2992] | I'm not sure you can pass binaries from the DOM to the plugin, if that is what you are trying. |
Graham 9-Oct-2008 [2993] | nearly there! |
Terry 9-Oct-2008 [2994] | You need a proxy. |
Graham 9-Oct-2008 [2995] | why? |
Terry 9-Oct-2008 [2996x2] | Can a plugin manipulate the DOM of the page? |
REBOL/Plugin includes a function callable from REBOL scripts, do-browser, that allows you to execute and retrieve the result of browser script code. This script code may manipulate the browser's document object model (DOM), giving you the ability to interact with other elements in the HTML page. | |
Graham 9-Oct-2008 [2998] | so I could load the image as normal and then use the plugin to access the image? |
Terry 9-Oct-2008 [2999x2] | yeah |
well, you access some JS.. and it manips the image | |
Henrik 9-Oct-2008 [3001] | Yes, the plugin can manipulate the DOM. I still don't think you can load binaries into the plugin from the DOM |
Terry 9-Oct-2008 [3002] | you can message the plugin |
Graham 9-Oct-2008 [3003x4] | eeek ..need to switch to plugin group |
Looks like my cheyenne server has crashed ... | |
http://compkarori.no-ip.biz:8001/ | |
static pages ( index.html ) work .. but cgi and rsp don't. | |
Terry 9-Oct-2008 [3007x2] | Security Error: Content at http://compkarori.no-ip.biz:8001/ may not load or link to chrome://firebug/content/highlighter.css. |
In other words, I can't see it in Firebug | |
Graham 9-Oct-2008 [3009] | Just a crash involving cgi and rsp. Static pages are still okay. |
Dockimbel 9-Oct-2008 [3010x2] | I've seen that happen here too in rare cases (cause undetermined). If you can run the %UniServe/clients/rconsole.r script on your server, you should check for this : |
probe uniserve/services/task-master/shared/pool-count | |
Graham 9-Oct-2008 [3012] | I'lll have to wait to I get to work .. unfortunately I don't have vnc access to this box |
Dockimbel 9-Oct-2008 [3013] | In some cases, this value can be messed up and Cheyenne doesn't seem able to start a new process anymore. I've made a small improvement in v0.9.19, but I'm unsure how if it will be really efficient. |
Graham 9-Oct-2008 [3014] | I'd better upgrade to 9.19 |
Dockimbel 9-Oct-2008 [3015] | Right, but test well your RSP webapps first with this new version before upgrading in production. |
Graham 9-Oct-2008 [3016x2] | Odd .. crashed on me again. the above probe said 8 |
This is with 9.19 | |
Dockimbel 10-Oct-2008 [3018] | Have you identified the pattern of actions causing that ? |
Graham 10-Oct-2008 [3019x2] | I was just calling imagemagick ... |
but now it's running okay again. Very odd. | |
Henrik 10-Oct-2008 [3021] | Sounds like the erratic crashes I've been getting. I thought I had found a pattern, but no. |
Terry 10-Oct-2008 [3022] | It's clearly divide by zero. |
Graham 10-Oct-2008 [3023] | Henrik, are your crashes also with the rsp engine? |
Henrik 10-Oct-2008 [3024] | Graham, I'm not sure. I have to restart Cheyenne to get it going again. |
Graham 10-Oct-2008 [3025] | are static pages still working when it crashes? |
Henrik 10-Oct-2008 [3026] | I honestly haven't checked. |
Graham 10-Oct-2008 [3027] | please check next time ... well, if you have some static pages! |
Henrik 10-Oct-2008 [3028] | I will. |
Dockimbel 10-Oct-2008 [3029] | It seems that the issue is caused by helper processes being stuck in "busy" mode and 'pool-count reaching the max value (8 in v0.9.18), so that any new CGI or RSP request coming won't find a free helper process. I still don't see why helper processes would remain stuck in "busy" mode. I'll run a few tests tomorrow to investigate that more deeply. |
Graham 10-Oct-2008 [3030] | can we change the max value? |
Dockimbel 10-Oct-2008 [3031x2] | sure |
it's not yet exported in config file, but you can change the default value in %Cheyenne.r source code. | |
Graham 10-Oct-2008 [3033] | ok |
Nicolas 10-Oct-2008 [3034x2] | Hi Henrick, I store my site at %/c/www/ |
sorry for the delayed response | |
Graham 11-Oct-2008 [3036x3] | Crashed again ... static pages still serving, just rsp down and this is with 9.19 |
All I'm doing is editing RSP pages, and running them. | |
running source code cheyenne.r on OpenSuse ( I think ) | |
