Bug 106662 – [EFL][GTK] checkSpellingOfString treats the multiple words as spelled correctly

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Grzegorz Czajkowski]

TextCheckerEnchant::checkSpellingOfString() method, treats the multiple words as spelled correctly if one of them is ok. For example, string such as "OK zz OK" is spelled correctly!

The method at the beginning assumes that the given string is spelled correctly, then it iterates over the words. In checkSpellingOfWord, if the word is ok, we mark it as spelled correctly and we do return. In the fact, the location and length of the previously misspelled words will be overwritten.

The patch touches only TextCheckerEnchant.cpp file which is building for EFL and GTK+ WebKit ports. I believe this regression is not connected with this patch.

The problem is not in checkSpellingOfWord() but in checkSpellingOfString(). What happens in the test case you mention is that after considering that zz is misspelled (and thus filling misspellingLocation and misspellingLength with the proper values), then it processes the 3rd word which is correct and thus it will overwrite the two variables with 0, -1, so the whole string will be considered correct. What you have to do is exit if one of the words is wrong.

This is wrong, the word is OK if it's correct according to at least one dictionary not the other way around.

stop checking next words if the current word is misspelled

Why are you adding a return value? In order to know if a word is correct you just need to check that misspellingLocation == -1, there is no need to add a boolean.

Sorry I shouldn't have set the r- not being a reviewer.

I thought about checking misspellingLocation == -1 after your review but when I started to make the proper changes, IMO the code wasn't look well. However, returning the same information (whether the word is misspelled or not) by return value and parameter is worst. Patch is coming.

nit "{" is still needed as the 'for' content wraps line.
