Bug 66346 – Incorporate newer, faster dtoa library

• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

[Mark Hahnenberg]

Our current dtoa library is a bit dated.  There is a newer, faster one that has been lifted out of the V8 project.  We should use it!

[Mark Hahnenberg]

The style bot freaked out because the new library was extracted from V8, and Google's coding style is like the bitwise-not of ours.  We should probably refrain from modifying the library to fit our style so we can more easily update it if any changes are made to it upstream.

Hey Mark,

From a quick look at this patch, it looks like you might be changing WebCore's CSS code to use the same number-to-string conversion as for JS?  Sorry if I'm mistaken, but if so, this isn't correct - the CSS spec prohibits exponential representation, all values should be simple decimal.

G.

Why is none of the new code in WTF inside the WTF namespace?

Reopen the bug report, because it  broke many JSC tests and layout tests on the Qt bot. Could you guys respect the WebKit policies and watch the bots?

Committed r94520: <http://trac.webkit.org/changeset/94520>

I agree with ossy: Please watch the bots!
Do we have any guidelines for 3rd party code? The change breaks many of our coding style guidelines and I don't know why even the simple ones (like include config.h) get ignored.
The new dtoa library does some stuff too, which is already done in WTF. I'm not a big fan of maintaining the #ifdef twice.

And finally: What does "The new library is much faster than the old one." mean exactly? I usually get a clear r-, when I don't include exact performance data into the ChangeLog!

> Do we have any guidelines for 3rd party code? The change breaks many of our coding style guidelines and I don't know why even the simple ones (like include config.h) get ignored.

There is precedent to having some flexibility on coding style for 3rd party code, since this makes it easier to continue to integrate future improvements.  However yes, one would expect some adaption to fit within our codebase, and yes, files definitely need to be including config.h.

> The new dtoa library does some stuff too, which is already done in WTF. I'm not a big fan of maintaining the #ifdef twice.

OOI are you just referring to replicating existing behavior of dtoa & DecimalNumber? - or of other basic types?  If re dtoa & DecimalNumber, then I believe the intention is to deprecate the existing code, but that this will involve a bit of work (specifically because these are used from WebCore by CSS code, that requires slightly different dtoa behavior that the new library may require a little adaption to produce).

> And finally: What does "The new library is much faster than the old one." mean exactly? I usually get a clear r-, when I don't include exact performance data into the ChangeLog!

I have to agree on this one, we really should be justifying changes like this with performance numbers.  Mark, what does this progress? - could you post some SunSpider/V8 benchmark numbers?

Sorry about that.  I attached some results to the Radar bug but neglected to do that here as well.

Thanks Mark!
