816312 - "Check for updates" spams logcat with parse errors for treating apps' JSON manifest files as XML, e.g. [JavaScript Error: "not well-formed" {file: "app://calculator.gaiamobile.org/manifest.webapp" line: 1 column: 1 source: "{"}]

Description

[Daniel Holbert [:dholbert]]

I just updated to the stable dogfood build that went up this morning, Build ID 20121127132302.

Using that build, I get this in my logcat output each time I manually check for updates:

}

These manifest files look like this:
 https://github.com/mozilla-b2g/gaia/blob/master/apps/homescreen/manifest.webapp
and indeed they do start with a {, because they're JSON...

I can only imagine we're complaining about them because something is trying to treat them as XML (or HTML)...?

I attached a more comprehensive snippet of my logcat output over at bug 816306 comment 1, FWIW.

Comment 1

[David Scravaglieri [:scravag]]

No reasons to block on that but some devs should clean that

Comment 2

[Daniel Holbert [:dholbert]]

(Yeah -- I'm not so much reporting it for the logcat-spam, as for the underlying bug that it represents -- we're apparently parsing these files incorrectly, which could be indicative of a broader issue.)

Comment 3

[Justin Lebar (not reading bugmail)]

Does this still happen?

Comment 4

[Daniel Holbert [:dholbert]]

No. None of this spam remains in latest dogfood/beta build (build id 20130116230203).
