RE: Sort not fixing order in equivalent subsequences

    I don't believe you want to rely upon the order, butr add the extra sort to for the key so you know and do not leave it to the current setup and with the next release changes.

 

Wags ;)

Subject: Sort not fixing order in equivalent subsequences

Hello all,

 

I can't find anything in the doc about whether Perl's sort function maintaining the order in equivalent subsequences. Suppose I have an array of hashrefs that looks like this:

 

{name => 'a', status => 0}, {name => 'b', status => 1}, {name => 'c', status => 1}, {name => 'd', status => 0}

 

and I sort { $a->{'status'} <=> $b->{'status'} }

 

Should I expect the result (order of the names) to always be ('a', 'd', 'b', 'c'), or could it be, for example, ('d', 'a', 'b', 'c') (i.e., could two entries with the same status value change relative order)?

 

Joe
