165698 - Big memory usage if many TT Fonts installed

Status: RESOLVED EXPIRED

(Core :: Internationalization, defect)

Description

[Mariusz Kryński]

When I had many (>300) True Type fonts installed in my system, Mozilla 1.0/1.1 
sometimes used >200MB memory during displaing some UTF-8 encoded pages
(http://sed.pl/test.html for example). System Slackware 8.0, XFree86 4.2 without
font server.

[Andrew Schultz]

are you saying >300 fonts or >300 font files
I have ~250 ttf font files, and memory usage went up to about 50MB.
the testcase just displays a symbol and some '?'

==> Intl

Where are the TT fonts installed and what code accesses them?

Do they show up in xlsfonts?

or

Are you accessing the TT fonts the direct FreeType2 code?
(http://www.mozilla.org/projects/fonts/unix/enabling_truetype.html)

Could you kindly please attach a -minimal- html page that displays this problem?

[Mariusz Kryński]

True Type fonts are included in FontPath (XF86Config) - avaliable for all X
applications. xlsfonts displays them (I'm not accessing TT fonts via FreeType2)
Minimal page that displays problem: http://sed.pl/test.html. In this page I
included some strange characters encoded in UTF-8  - these characters are
extracted from one of normal web pages.

If I had to speculate I would first guess that the memory is used for the
"per-char" metrics.

Reporter can you reproduce this bug with a newer build (1.4 final)?
If not, then please close this bug as worksforme. Thanks.

shanjian is no longer working on mozilla for 2 years and these bugs are still
here. Mark them won't fix. If you want to reopen it, find a good owner first.

Mass Re-open of Frank Tangs Won't fix debacle. Spam is his responsibility not my own

you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
