Invalid selectors can cause a subsequent valid selector not to work

Reported by: Owned by:

Component: selector Version: 1.8.0
Keywords: Cc:
Blocked by: Blocking:

In jQuery 1.8.0 the (obviously invalid) code:


results in the error:

TypeError: groups is null

(jquery.js Line 4664)

Then the next time you run a valid pseudoclass selector (eg ":first") you get the following error:

Error: Syntax error, unrecognized expression: unsupported pseudo: last

(jquery.js Line 4512)

Selectors run after this appear to work normally.

There are two problems here:

Firstly any selector run after the offending ":first.not(.asd)" doesn't work.

Secondly, previous jquery versions allowed ":first.not(.foo)" to pass without an error. I came across this bug as the shopping cart software we use pulls the latest version from Google, and had the above invalid selector (obviously they mean ":not" rather than ".not" but never noticed). When 1.8.0 made it onto Google's servers certain things no longer worked across a range of sites (I'm not really blaming jQuery here, but there was a change in behaviour. Is it intended that an error of some sort be raised here?)

Id like to change the title of this bug to something like

"Invalid selectors can cause a subsequent valid selector not to work" as the title I put doesn't really get across that this is causing problems, but I can't seem to change the title.
