Hebrew text in Pepper Flash is backwards

Project Member Reported by, Jun 25 2012

Issue description

Chrome Version       : 21.0.1180.4
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)

It started in the past month or so... was too overloaded to check when i first saw it.
Chromium builds are unaffected (because Pepper Flash is needed).

How to reproduce:
0. Use Pepper Flash
1. Open a flash video with Hebrew text on it, for example
2. Hover over the suggestions at the end to see the backwards Hebrew

Works fine if I disable the Internal Flash plugin in exchange for the original one.

Brett: Do you know who an look at this, this sounds like a pretty bad regression :(

The above screenshots were taken on Windows. (NPAPI Flash on Windows is correct, I assume.)

Pepper Flash is broken on all platforms, in the same way.

NPAPI Flash on Mac is broken, but in a different way (attached)!

NPAPI Flash on Linux is broken in the same way as Pepper Flash.

can you provide bisect info for this regression issue?
i'm no sure how since pepper flash isn't in the chromium builds

Trung, here's the deal:
* Pepper flash is correctly splitting the BiDi runs but is drawing the letters inside the hebrew runs reversed.
* NPAPI flash on Windows is correct, as you say.
* NPAPI flash on Mac is displaying the string with LTR directionality rather than as RTL, this is causing the difference in the string display.  It's not reversing letters.

I think the bug here is that Pepper flash is drawing RTL runs reversed.
regression window from chrome builds will help narrow down the issue. thanks!

could you find regression window from the archived Chrome builds directory? thanks!
We don't need a regression window. This was always broken.

It's OK using the beta channel build though
Google Chrome	20.0.1132.43 (143823) beta-m
OS	Windows
Status: Assigned
(To clarify, brettw's statement was about it always being broken in Pepper Flash.)

Chrome 20 Beta uses NPAPI Flash.

I have a patch for this, currently writing tests.

Fix confirmed under Windows, thanks :) I'm glad the issue won't reach the stable channel

Google Chrome	22.0.1189.0 (144640) canary
OS	Windows
WebKit	537.1 (@121350)
JavaScript	V8 3.12.4
Labels: Merge-Requested
I don't see any crashes on canary for this so I'd like to merge to 21. Otherwise Flash won't work for RTL text.

The patch isn't super trivial but I don't think it's very risky. This code should only be run with Flash now so there's little risk to other features as well.
We're okay with this being in the M21 Beta2.
