Re: [web-devel] juliusFile in yesod 0.8 eating all memory

Nice work! In the switch to aeson, the old types were just removed from Julius- we should add the aeson types back in now or otherwise make this easier. On Fri, Apr 29, 2011 at 7:32 AM, JP Moresmau wrote:

instance (ToJSON a)=> ToJavascript a where toJavascript =toJavascript . toJSON

That used to work but now seems to go into an infinite loop. I've replaced it by:

instance (ToJSON a)=> ToJavascript a where toJavascript =fromLazyText . decodeUtf8 . encode . toJSON

and everything works again. Not very elegant, have I missed something? Shouldn't that instance be part of Yesod somewhere? I mean if we standardize on Aeson, and we want variables in Javascript, it makes sense to serialize ToJSON instances in a Julius template.

juliusFile, I'm not running any scaffolded site, I've built everything with 1s and 0s. (-: Changing to juliusFileDebug results in the same behavior.

Are you running juliusFile or juliusFileDebug? (The scaffolded site uses the latter by default.)

Hi all,

I've just upgraded to Yesod 0.8. I've changed all my Strings into Texts, and all my Data.JSON.Types into Data.Aeson.Types. I use these JSON objects in julius templates, by adding the orphan instance: instance (ToJSON a)=> ToJavascript a where toJavascript =toJavascript . toJSON

(Removing that instance causes compilation error, and I had it when I was using json-types). addJulius works fine when it contains Javascript code. However on one page I use juliusFile to load an external template. This eats all my memory and never returns under Warp when I launch the compiled exe (I see "thread killed" messages in the console, though), and in GHCi crashes with "out of memory". The code hasn't changed and was working fine in yesod 0.7 before the upgrade. If I remove juliusFile the page displays instantly.

Any idea? I'm a bit stumped. I suppose I'm going to remove each of my variables in the julius file to narrow it down, but if anybody has any insight...

Thanks!
