Description Aryeh Gregor (not reading bugmail, please e-mail directly) 2008-01-24 03:10:18 UTC
$ grep "\([^\!=]==\|\!=\)\s*''" {includes,skins,languages,maintenance,math,../extensions}/{*,*/*,*/*/*,*/*/*/*}/*.php *.php 2> /dev/null | wc -l

That's a lot of == '' and != ''.  These should all be examined and fixed to either check strictly (if that's desired) or, I guess, drop the equality check, since that's more explicit.  Of course, this doesn't count all the cases where you say !$var and assume strong type checking, but there's not much hope for automatically detecting those.  Core looks a little better:

$ grep "\([^\!=]==\|\!=\)\s*''" {includes,skins,languages,maintenance,math}/{*,*/*,*/*/*}/*.php *.php 2> /dev/null | wc -l

I'll get on some of these, maybe, if I have the time.
Comment 1 Aryeh Gregor (not reading bugmail, please e-mail directly) 2008-01-24 03:41:11 UTC
Of course, my bash globbing was totally off . . .

$ grep "\([^\!=]==\|\!=\)\s*''" {includes,skins,languages,maintenance,math,../extensions}/{,*/,*/*/,*/*/*/}*.php *.php 2> /dev/null | wc -l
$ grep "\([^\!=]==\|\!=\)\s*''" {includes,skins,languages,maintenance,math}/{,*/,*/*/,*/*/*/}*.php *.php 2> /dev/null | wc -l

That looks less pleasant.

Comment 3 Antoine "hashar" Musso (WMF) 2008-07-19 13:14:08 UTC
All on one line:
find . -name '*php' -exec grep -H "\([^\!=]==\|\!=\)\s*''" {} \;
