Bug 29123 – Fails to parse the "d" attribute of a path if a command starts with a '.'

• Component: SVG
• Status: VERIFIED FIXED

[Rafał Rutkowski]

The following path will not be parsed
<path d="M.1 0.1l0 .3 .2 0" />
The cause is the last command: ".2 0", which starts with a '.'.

The following examples work fine:
M.1 0.1l0 .3 +.2 0
M.1 0.1l0 .3 0.2 0
M.1 0.1l0 .3 l.2 0
M.1 0.1l0 .3

Test case:
http://strony.aster.pl/rrutkows/test_cases/webkit/svg_path_parse_error/L.svg

Result:
Nothing is displayed. An error appears in the Chrome console:
Error: Problem parsing d="M.1 0.1l0 .3 .2 0"

Expected result:
A black shape resembling a capital letter 'L' should be displayed. Works on Opera, Firefox and IE+Adobe SVG Viewer.

Tested on Safari 4.0 (530.17) and Chrome 4.0.206.1 (532.0)

In the WebKit project we require regression tests checked in along with bug fixes.

There's already a test of the path parser in LayoutTests/svg/dom/path-parser.html so for this bug you could probably add some tests cases to that.

review- because of lack of a test
