109256 - Attempt to display Plane 1 fonts causes Mozilla to crash Trunk M096 [@ nsTextFrame::TextStyle::TextStyle]

Status: RESOLVED DUPLICATE of bug 108105

(Core :: Layout: Images, Video, and HTML Frames, defect)

Description

[Andrey ``Bass'' Shcheglov]

Currently there's only one True Type font capable of displaying Plane 1 --
Code2001 (http://home.att.net/~jameskass/code2001.htm), it works fine with MSIE
6, but Mozilla crashes while rendering any of the test pages
(http://www.hclrss.demon.co.uk/unicode/old_italic.html,
http://www.hclrss.demon.co.uk/unicode/gothic.html,
http://www.hclrss.demon.co.uk/unicode/deseret.html) with the specified font.

Reporter:  What build are you seeing this on?  You can find a user-agent string
like the one above by going to Help, About Mozilla.

[Andrey ``Bass'' Shcheglov]

Sorry, I just forgot to provide the UserAgent string. Here it is:

Reporter:  Can you please download a nightly and retest this bug?  Perhaps it's
been fixed already.

Attachment: That's how it looks in MSIE

mozilla.org displayed with Code2001 font in MSIE v6.0

Attachment: ...and that's how it looks in Mozilla

Mozilla does render pages with Code2001, but it takes from 3 to 5 minutes to
render 
one.

Comment 6

[Andrey ``Bass'' Shcheglov]

I managed to view a page in the latest build (v0.9.5+.2001111303) -- or rather
Mozilla managed to display it (see attachment #2 [details] [diff] [review]). The only issue is that it ate
up all available memory (I'm running the system with 320M of RAM), so that
Windows itself stopped responding -- and then crashed. I was unable to make a
screenshot of Mozilla window at the very moment of crash as there were no free
memory to store the image in the clipboard.

[Andrey ``Bass'' Shcheglov]

Bugzilla automatically created a hyperlink in the above comment -- ignore it. I
meant the second attachment for *this* bug.

Comment 8

[Alex Vincent [:WeirdAl]]

Reporter:  Okay, my system doesn't have a Code2001 font on it.  :)  I've never
heard of it, where do you get it from?  I still don't have much of a clue on
what "Plane 1 fonts" are.

Also, are you running a TalkBack build?  If so, please go to your Mozilla
directory to \bin\components\talkback.exe and run the program.  You should get
some TalkBack ID #'s which Mozilla developers can use to identify what has
caused your crash.

Comment 9

[Andrey ``Bass'' Shcheglov]

Just for reference. Plane 1 is a section of Unicode (http://unicode.org) that
covers Etruscan, Gothic, and Old Persian Cuneiform characters.

Talkback information follows.

Comment 12

[Andrey ``Bass'' Shcheglov]

I explored the problem thoroughly. Code2001 is not the cause of crashes.
Still, there *is* a bug.

Font properties for Win32 platform are stored in winpref.js file. Here's an example:

pref("font.name.serif.<character coding>", "<typeface>"); // Times New Roman
pref("font.name.sans-serif.<character coding>", "<typeface>"); // Arial
pref("font.name.monospace.<character coding>", "<typeface>"); // Courier New
pref("font.name.cursive.<character coding>", "<typeface>"); // Comic Sans MS
pref("font.name.fantasy.<character coding>", "<typeface>");

There're two encodings I encountered promlems with.

1. Unicode ("x-unicode")

Default settings:
=================
pref("font.name.serif.x-unicode", "Times New Roman");
pref("font.name.sans-serif.x-unicode", "Arial");
pref("font.name.monospace.x-unicode", "Courier New");
pref("font.name.cursive.x-unicode", "Comic Sans MS");

Whichever fonts you specify for Unicode, no matter in local or in global
preferences, your settings are understood correctly (Mozilla displays font names
in Preferences-->Appearance-->Fonts-->Unicode), but *ignored*. Anyway, UTF-7 and
UTF-8 pages are rendered with Times New Roman, Arial and Courier New.

2. User-defined ("x-user-def")

Default (global) settings are absent. As long as there's no global or local
prefs for this encoding, pages are displayed using those default Times New
Roman, Arial and Courier New, though Mozilla, being unable to find font settings
for x-user-def, says that it uses "Andale Mono IPA" for displaying all five
styles. (Andale Mono IPA is the first font in my Windows font list, sorted
alphabetically.)

But *if* you dare to specify a font for the user-defined enc., no matter in
local or global prefs, Mozilla crashes while displaying a page. Even if you
explicitly specify "Times New Roman" for serif, "Arial" for sans serif and
"Courier New" for monospaced (i.e. if you override the defaults with the
defaults, as these fonts are used for rendering if nothing is specified) -- then
Mozilla will crash!

And Code2001 is not the problem. If you set this font as the default for
displaying any encoding other than ones mentioned above, pages *will* be
displayed with this font, provided it contains the appropriate glyphs. The
crashes described in previous comments occured while trying to use Code2001 font
plus User-defined encoding.

Comment 13

[Andrey ``Bass'' Shcheglov]

[Unicode part] Font sizes are ignored, too. "Allow documents to use other fonts"
option is OFF.

[User-defined encoding part] This bug is related to bug 103673.

Comment 14

[Ashley Bischoff (blog at handcoding.com)]

Reporter: It would be helpful if you could provide a Talkback ID. 
(you can get the talkback id by running <moz-dir>/bin/components/talkback)

You may also wish to try a fresh profile. You can manage/create profiles with
"mozilla.exe -profilemanager".

Comment 15

[Andrey ``Bass'' Shcheglov]

The talkback information is already provided. See attachment 57991 [details].

Comment 16

[Ashley Bischoff (blog at handcoding.com)]

Yes, I see the attachment :). However, an actual Talkback ID would be handy, as
the talkback information you provided is not in the typical talkback format.

Comment 17

[Andrey ``Bass'' Shcheglov]

Then what is "Talkback ID"? I'm afraid I misunderstand you. Is it an "Incident
ID" value in the table of incidents? If so, you can take an incident
#TB38170507Y, for instance.

Comment 18

[Andrey ``Bass'' Shcheglov]

And the same behaviour with a fresh profile. Unicode settings are ignored,
selecting the "User-defined" encoding when having any preferences set for this
encoding causes the program either to crash or to eat all memory and crash on
display of the next page.
