Bug 17487 – HTMLInput mysteriously fails to work if ICU dat file is missing

• Component: Text
• Status: RESOLVED FIXED

[Sriram Neelakandan]

HTML input box will not work if ICU dat file is not found.

This happens due to failure in ICU's Textbreakiterator

If an appropriate error message is displayed it will be useful for developers.

I don't see how this is a valid bug.  If your ICU installation is broken and you are using a WebKit port that relies on ICU then many things will not work.

I use GTK port. Its not that many things don't work. Every thing works but for HTMLTextInput.

I already have sent a patch for the same. It just prints a message to indicate failure. Can u review it ? 

Please see this link

After taking care of Coding Guidelines as mentioned by David, 
I have attached a modified version of the same patch to this bug (http://bugs.webkit.org/attachment.cgi?id=19336&action=view)

I think that adding logging for this case is a very good idea. I also had a occasion when debugging an issue caused by a missing (actually, non-matching) ICU dat file took longer than it should have taken.

We normally use LOG_ERROR macro in cases like this, not fprintf(stderr, ...) - could you please update the patch to use it? In the future, you can mark a patch for review by clicking "Edit" link - this guarantees that it won't get lost.

Can you please also create the patch using svn-create-patch.  See <http://webkit.org/coding/contributing.html> for more information.

I have corrected the patch as per coding guidelines.
also used LOG_ERROR instead of fprintf.

Also the patch has been taken using svn-create-patch

There are still some issues with this patch, but I'm going to say r=me and fix those when landing.

1. There is no ChangeLog.

2. "+#include <stdio.h>" is no longer needed without fprintf.

3. 
+    if (!createdIterator) 
+    {
  We put opening brace on the same line as "if".

4. Instead of a combination of LOG_ERROR and ASSERT, one can use ASSERT_WITH_MESSAGE.
