[12:59:08 CDT(-0500)] <EricDalquist> freaking javascript
[12:59:09 CDT(-0500)] <EricDalquist> http://directwebremoting.org/blog/joe/2007/03/05/json_is_not_as_safe_as_people_think_it_is.html
[12:59:55 CDT(-0500)] <athena> evil
[13:00:17 CDT(-0500)] <athena> probably still need to talk about what we want to do for REST feed security
[13:00:28 CDT(-0500)] <EricDalquist> I'm doing more looking into CSRF protection for a portlet I'm working on here
[13:00:38 CDT(-0500)] <EricDalquist> and finding all sorts of badness that can be done
[13:00:42 CDT(-0500)] <athena> :/
[13:00:56 CDT(-0500)] <EricDalquist> primarily because JS is so flexible
[13:01:09 CDT(-0500)] <athena> yeah
[13:14:09 CDT(-0500)] <EricDalquist> hrm ok I re-read that looks like if you do true json
[13:14:10 CDT(-0500)] <EricDalquist> and have {} be your top level element the data is safe
[13:14:11 CDT(-0500)] <EricDalquist> it isn't safe when the top level element is an []
[13:14:25 CDT(-0500)] <athena> gotcha
[13:14:30 CDT(-0500)] <athena> don't know that it's even possible to make it unsafe using the spring json view then
[13:14:37 CDT(-0500)] <EricDalquist> I don't think it is
[13:14:39 CDT(-0500)] <athena> yeah
[13:14:40 CDT(-0500)] <athena> think the view requires a map
[13:14:49 CDT(-0500)] <EricDalquist> http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/web/servlet/view/json/MappingJacksonJsonView.html#setPrefixJson(boolean)
[13:14:50 CDT(-0500)] <EricDalquist> interesting feature
[13:18:02 CDT(-0500)] <EricDalquist> interesting, another mitigation approach is to look for "Content-Type: application/json" in the request
[13:18:12 CDT(-0500)] <EricDalquist> that is never set by a browser when making a request from a <script> tag
[13:18:26 CDT(-0500)] <EricDalquist> and in that case just throw a 400 class error
[13:28:16 CDT(-0500)] <athena> interesting
[13:28:32 CDT(-0500)] <athena> that seems like a workable approach
[13:28:55 CDT(-0500)] <athena> i like these solutions that don't seem to impact things like cachine
[13:28:57 CDT(-0500)] <athena> er, caching
[13:33:43 CDT(-0500)] <EricDalquist> yeah
[13:36:43 CDT(-0500)] <EricDalquist> the only down side of that one is trying to view the JSON response directly in a browser would get you the unauthorized error
[13:43:09 CDT(-0500)] <athena> hm, which one would?
[13:43:33 CDT(-0500)] <EricDalquist> the server checking the accept or content-type headers on the requet
[13:44:01 CDT(-0500)] <EricDalquist> the point of it is to make sure your JS always sets the json content type and accept headers
[17:35:35 CDT(-0500)] <rickard> holdorph: You there?
[17:36:06 CDT(-0500)] <holdorph> partially (somewhat busy in another window, but will respond here as I'm able)
[17:36:39 CDT(-0500)] <rickard> Ok. Sorry to bother you, but I'm stuck on an XSL/XPath issue that you might be able to help me with.
[17:37:43 CDT(-0500)] <rickard> <xsl:for-each select="tab[starts-with(@externalId, $SOME_VARIABLE)]>
[17:38:24 CDT(-0500)] <rickard> This loops over all tab elements whose externalId attribute starts with $SOME_VARIABLE. This works.
[17:40:21 CDT(-0500)] <rickard> In the for-each, I then have to check if there are tab elements that start with the externalId of the current element in the loop.
[17:40:24 CDT(-0500)] <rickard> For this, I have:
[17:40:32 CDT(-0500)] <rickard> <xsl:variable name="CURRENT_TAB" select="@externalId"/>
[17:41:41 CDT(-0500)] <rickard> <xsl:variable name="HAS_SUBTABS" select="count(../tab[starts-with(@externalId, $CURRENT_TAB)) &gt; 0"/>
[17:42:02 CDT(-0500)] <rickard> This also works. However, is there a way to get rid of the CURRENT_TAB variable?
[17:43:20 CDT(-0500)] <rickard> If I just replace it into the query, it would result in:
[17:43:31 CDT(-0500)] <rickard> <xsl:variable name="HAS_SUBTABS" select="count(../tab[starts-with(@externalId, @externalId)) &gt; 0"/>
[17:43:37 CDT(-0500)] <holdorph> i'm sorry, but XSL is not my strong point, and given that my XSL is so weak, I don't know any of uPortal's XSL. but maybe athena who's logged into the channel will see the question. she does more with it then I do.
[17:43:51 CDT(-0500)] <rickard> Alright, no problem. Thanks anyway.
[17:44:07 CDT(-0500)] <athena> hyea
[17:44:10 CDT(-0500)] <athena> er, heya
[17:44:25 CDT(-0500)] <athena> i don't think there's a way to delete a variable in XSLT
[17:44:31 CDT(-0500)] <rickard> Hi
[17:44:54 CDT(-0500)] <rickard> Well, not delete. I'm just curious if I can "optimize" my code to not use the CURRENT_TAB variable.
[17:45:10 CDT(-0500)] <athena> oh, i see now
[17:45:18 CDT(-0500)] <athena> errrr
[17:45:21 CDT(-0500)] <athena> i'd probably just leave it
[17:45:24 CDT(-0500)] <rickard>
[17:45:35 CDT(-0500)] <athena> what you have is probably pretty optimized by XSLT's standards, unfortunately
[17:45:42 CDT(-0500)] <athena> that may be the most readable solution
[17:45:47 CDT(-0500)] <rickard> True
[17:45:52 CDT(-0500)] * athena hates using XSLT variables
[17:46:02 CDT(-0500)] <rickard> I just have a bunch of variables and wanted to clean it up a bit if possible.
[17:46:21 CDT(-0500)] <rickard> I'll ask in #xml. Maybe they have some ideas.
[17:46:33 CDT(-0500)] <athena> sounds like an excellent solution
[17:54:52 CDT(-0500)] <rickard> athena: By the way. I've developed an in-house alternative to SimpleContentPortlet that uses edit mode to allow for inline editing of content. In other words, don't feel the need to rush the i18n additions to SimpleContentPortlet. At least not on my behalf.
[17:55:04 CDT(-0500)] <athena> oh, hurray!
[17:55:21 CDT(-0500)] <athena> sorry there's been such a delay on that, but really glad you at least have something to tide you over for now
[17:55:33 CDT(-0500)] <athena> sadly my time for elective development has been umm . . . nonexistant
[17:56:12 CDT(-0500)] <holdorph> btw, rickard, that sounds a lot like the other content management portlet that's currently in incubation
[17:56:18 CDT(-0500)] <holdorph> being led by misagh
[17:56:34 CDT(-0500)] <holdorph> you might see if you can share some code with him.
[17:56:44 CDT(-0500)] <athena> i need to ping misagh again
[17:56:56 CDT(-0500)] <athena> see if we can eventually collaborate on a superset of the features in each portlet
[17:56:58 CDT(-0500)] <rickard> Well, there's not a lot to share really. It's dead simple.
[17:57:08 CDT(-0500)] <rickard> At least my portlet.
[17:57:11 CDT(-0500)] <athena> tried his most recent version lately - it's a lot easier to install now
[17:57:47 CDT(-0500)] <athena> rickard's mod adds i18n support to the existing portlet preference based persistence, i think
