Uploader Broken! > Re: [Commits] svn commit: 6068

[Eli Cochran]

Apologies for the cryptic message earlier, I was in a bit of panic  
over my check-in of broken code.

The broken-ness was just a garden variety typo.

However, the slowness was because we rephrased our selector for  
fileRows from "tr:not(#queue-row-tmplt)" to ":not(#queue-row-tmplt)".

tr:not(#queue-row-tmplt) means "all *row elements* that do not have an  
id of "queue-row-tmplt".

while

:not(#queue-row-tmplt) means *any and all* elements that do not have  
an id of "queue-row-tmplt".

so while the former forced jQuery to inspect every row element and  
return all but one of those rows, the latter selector forced jQuery to  
inspect each and every element in the container and return all but one  
of those.

It's really quite surprising that all it did was slow down.
