102940 - grayed out folders in folder list have fonts that are incorrectly spaced

Status: VERIFIED WORKSFORME

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Christopher Blizzard (:blizzard)]

Build is from the morning of October 3, 2001 on the tip.

I have grayed out folders in my IMAP folder list and the fonts are really
strange.  They have spaces in between them.  I'll start looking at checkins and
attach a screenshot in a moment.

This was caused by bstell's checkin to nsFontMetricsGtk.cpp.  Brian, may I back
it out or do you think that you can fix it?

What OS/rev?

How does one grey out a folder?

What theme are you using?

Comment 5

[Frank Tang]

bstell- pleae mark it as ASSIGN if you agree to work on it. 

Comment 6

[Frank Tang]

The font in the screen shot looks very similar to 102623 

Comment 7

[Christopher Blizzard (:blizzard)]

Modern skin, Red Hat 7.<mumble>.  These grayed out folders are directories on
the imap server.

how can I grey oot a folder so I can try to reproduce / debug this?

Comment 9

[Jungshik Shin]

Can you set the env. variable NS_FONT_DEBUG and see what font
is used for the greyed-out IMAP folder? Is it wadalab-gothic?
(ref. bug 102643). My very wild guess is that 
when there's NO CSS spec. for a certain element, kinda 'random'
(or the first matched one)font among some 'hard-coded' family of 
fonts is picked. The directory name on IMAP server may not
be assigned an 'style'. Neither is the email body (when fixed-width
font is specified to be used. ref. bug 102643 and perhaps bug 83250)

Chris: can you find and temporarily disable the alias-helvetica?

When will IMAP directory grayed out on Modern Skin? I cannot make it happen 

Comment 14

[Christopher Blizzard (:blizzard)]

I have a grayed out folder on my IMAP server since it's a directory that you
can't actually put messages in.

Comment 15

[Jungshik Shin]

In the font trace (attachment 52039 [details]), I found the following
lines (and many more similar lines for alias-helvetica):

bitmap (non-scaled) font:
-alias-helvetica-bold-i-normal--17-120-100-100-c-0-iso8859-1,
nsFontMetricsGTK.cpp 3224
outline scaled font: -alias-helvetica-bold-i-normal--0-0-0-0-c-0-iso8859-1,
nsFontMetricsGTK.cpp 3235
bitmap (non-scaled) font:
-alias-helvetica-bold-i-normal--17-120-100-100-c-0-jisx0208.1983-0,
nsFontMetricsGTK.cpp 3224
font.scale.outline.min.ja = 10, nsFontMetricsGTK.cpp 2969
font.scale.bitmap.min.ja = 16, nsFontMetricsGTK.cpp 2978
font.scale.bitmap.oversize.ja = 1.2, nsFontMetricsGTK.cpp 2989
font.scale.bitmap.undersize.ja = 0.8, nsFontMetricsGTK.cpp 3001
outline scaled font:
-alias-helvetica-bold-i-normal--0-0-0-0-c-0-jisx0208.1983-0,
nsFontMetricsGTK.cpp 3235


I believe alias-helvetica fonts are outline fonts, but
somehow XFontList() returns two entries for each of
them when it's asked to come up with a list of matching
'-alias-helvetica-*-*-*-*-*-*-*-*-*-*-iso8859-1' :

-alias-helvetica-bold-i-normal--17-120-100-100-c-0-iso8859-1
-alias-helvetica-bold-i-normal--0-0-0-0-c-0-iso8859-1

You can check this by comparing the results of the following:
 
  xlsfonts -fd  '-alias-helvetica-*-*-*-*-*-*-*-*-*-*-iso8859-1'| grep 17
and
  xlsfonts | egrep 'alias-helvetica.*8859-1' | grep 17 


The former output has 
-alias-helvetica-bold-i-normal--17-120-100-100-c-0-iso8859-1
but the latter does not. I think that means
'-alias-helvetica-bold-i-normal--17-120-100-100-c-0-iso8859-1'
is kind of 'bogus' and should be skipped. (I gave more
details in my comments to bug 94327)
My patch to bug 94327 (attachment 53094 [details] [diff] [review]) takes care of 
skipping this 'bogus' fonts.

With these 'bogus' bitmap-unscaled fonts removed,
I believe, Mozilla would pick genuine bitmap-unscaled
'-adobe-helvetica' at 17px even with Brian's patch.
 

Chris, why don't you check in both Brian's patch to bug
94327 and my additional patch (attachment 53094 [details] [diff] [review]) and
see what happens? 

Another thing to check out is whether
-alias-helvetica-* fonts have indeed *wrong* spacing
(that is, Latin glyphs have unusually wide width).
This can be easily checked with 'xfd'. 
If that's the case and Mozilla 
happens to choose one of them for Latin rendering,
there's not much Mozilla can do.
The font server is to blame (e.g. truetype font
server backend for XF86 4.x has this problem)
and only remedy is remove those fonts from fonts.dir.

push to 1.01, but hope it can be resolved sooner.

Comment 19

This bug was logged when bug 94327 was first checked in. Because of time
constraings the code for bug 94327 was backed out then later put in.

Since there was no new discussion when the code for bug 94327 when back
in I assume this is no longer a problem. Thus I recommend it be closed and
if someone still finds it a problem it could be reopened.

I haven't seen it in a long time.

Since this does not appear to be an issue I'm closing this bug.

If anyone sees this behavior kindly reopen it.
