Bug in font charset detection causing memory leak #4778

vakhoir · 2020-01-28T14:05:18Z

Detected while testing #4695

Observed behaviour

Certain unicode characters are not displayed properly with some of the fonts, even when the font contains the character. This leads to constant re-baking of the font, and a huge (~100MB/s) memory leak.

Expected behaviour

Characters that are in a font are rendered correctly. If they aren't handled by the font, a fallback is used or an error is thrown. In either case, there should be no memory leaks.

Steps to reproduce

Set language to German
Start new game
Open the Equipment Market (or any view that displays a formatted money amount > $1 000). The formatted amount of money displayed should contain a '?' like in the following screenshot:

Causes

This is one of those bugs where a number of things has to happen at the same time for it to come up. First of all in the format_money function, if the locale has a white space set as the thousand-separator, we overwrite that with a unicode fixed space:

pioneer/src/utils.cpp

Lines 43 to 45 in 99a2e0b

    
           std::string groupSep = std::string(Lang::NUMBER_GROUP_SEP) == " " ? 
        
           	"\u00a0" : 
        
           	Lang::NUMBER_GROUP_SEP; // space should be fixed space

That's why it's necessary to switch to German, or another language that use a white space as the thousand-separator, in order to reproduce the bug.

When we try to render the character ImGui's FindGlyph function says it's not there, so a fallback character is displayed instead, and the fixed space is "reported missing", therefore PiGui tries to add it explicitly to the font, and rebake it. The twist is that PiGui says PionilliumText22L-Medium.ttf contains the \u00a0 fixed space, so it wants to keep using that font:

pioneer/src/PiGui.cpp

Lines 139 to 146 in 99a2e0b

    
           PiFont &pifont = pifont_iter->second; 
        
           for (PiFace &face : pifont.faces()) { 
        
           	if (face.containsGlyph(glyph)) { 
        
           		face.addGlyph(glyph); 
        
           		m_should_bake_fonts = true; 
        
           		return; 
        
           	} 
        
           }

But when ImGui calls stbtt_FindGlyphIndex it can't find it, 0 is returned and the whole thing starts over in the next frame

pioneer/contrib/imgui/imstb_truetype.h

Lines 1501 to 1518 in 99a2e0b

    
           while (entrySelector) { 
        
              stbtt_uint16 end; 
        
              searchRange >>= 1; 
        
              end = ttUSHORT(data + search + searchRange*2); 
        
              if (unicode_codepoint > end) 
        
                 search += searchRange*2; 
        
              --entrySelector; 
        
           } 
        
           search += 2; 
        
           { 
        
              stbtt_uint16 offset, start; 
        
              stbtt_uint16 item = (stbtt_uint16) ((search - endCount) >> 1); 
        
              STBTT_assert(unicode_codepoint <= ttUSHORT(data + endCount + 2*item)); 
        
              start = ttUSHORT(data + index_map + 14 + segcount*2 + 2 + 2*item); 
        
              if (unicode_codepoint < start) 
        
                 return 0;

So is it a Pioneer bug or an ImGui bug? A quick test seems to indicate that the "fixed space" character is indeed defined in the Pionillium font:

$ hb-shape PionilliumText22L-Medium.ttf `echo -ne "\u00a0"`
[space=0+235]

So it seems the problem is on ImGui side, but at the moment I can't make heads or tails out of what's going on in stbtt_FindGlyphIndex. Maybe someone else knows off the top of their head, if not I'll resume work on this later.

P.S.

I'm pretty sure the bug is in font-parsing now. When I was debugging this I originally misunderstood the meaning of the containsGlyph function here:

pioneer/src/PiGui.cpp

Lines 139 to 146 in 99a2e0b

    
           PiFont &pifont = pifont_iter->second; 
        
           for (PiFace &face : pifont.faces()) { 
        
           	if (face.containsGlyph(glyph)) { 
        
           		face.addGlyph(glyph); 
        
           		m_should_bake_fonts = true; 
        
           		return; 
        
           	} 
        
           }

So I thought "Wait, why are we adding a glyph when the font already contains it? Shouldn't it be the other way around?" and added a negation. It actually helped! Kind of. The character ranges on Pigui-side are hardcoded (we ~~should probably~~ have to (see below) change that somehow, as well as the name of the containsGlyph function and m_ranges variable), so the alternative fallback fonts like DejaVuSans.ttf jumped into the AddGlyph block. On ImGui side the fixed space was also detected and displayed correctly, that's valid because that font also contains the character:

$ hb-shape DejaVuSansMono.ttf `echo -ne "\u00a0"`
[nonbreakingspace=0+1233]
$ hb-shape DejaVuSans.ttf `echo -ne "\u00a0"`
[nonbreakingspace=0+651]

Although it looks like it's defined differently, maybe that has something to do with it? Can't say I know much about the ttf format.

P.P.S

After thinking about it more, I guess the bug is also on the Pioneer side.

pioneer/src/PiGui.cpp

Lines 745 to 748 in 99a2e0b

    
           PiFont uiheading("orbiteer", { 
        
           								 PiFace("DejaVuSans.ttf", /*18.0/20.0*/ 1.2, { { 0x400, 0x4ff }, { 0x500, 0x527 } }), PiFace("wqy-microhei.ttc", 1.0, { { 0x4e00, 0x9fff }, { 0x3400, 0x4dff } }), PiFace("Orbiteer-Bold.ttf", 1.0, { { 0, 0xffff } }) // imgui only supports 0xffff, not 0x10ffff 
        
           							 }); 
        
           PiFont guifont("pionillium", { PiFace("DejaVuSans.ttf", 13.0 / 14.0, { { 0x400, 0x4ff }, { 0x500, 0x527 } }), PiFace("wqy-microhei.ttc", 1.0, { { 0x4e00, 0x9fff }, { 0x3400, 0x4dff } }), PiFace("PionilliumText22L-Medium.ttf", 1.0, { { 0, 0xffff } }) });

This is the bit I mentioned, where the charsets are hardcoded, the last argument in each PiFace constructor is the range of valid characters the font is supposed to support, and Orbiteer and Pionillium have it set to from 0x0000 to 0xffff. Even if the fonts contained every single unicode character, this would still be wrong to have the range hardcoded. But since they don't have every character, this means we're treating that range as a preference - "ImGui, try to use this font to handle these characters, if you can, please". In that case we need to also handle the case when ImGui tells us it cannot handle that character with that font.

Conclusions

We need to remove the hardcoding of m_ranges in PiFace. Either try to read the valid character ranges from the file directly, or to save the glyphs we already tried loading with ImGui in a variable, and use it to return false in containsGlyph the next time the same glyph comes up.
Should we drop that whitespace / unicode fixed space replacement in format_money? We seem to be able to render whitespaces just fine.
(Optional) figure out why ImGui can't read the fixed space character for Pionillium
(Optional) Rename m_ranges to something like m_valid_ranges and containsGlyph to canHandleGlyph, or describe what they do in comments. It's hard to figure out what these are actually for at first glance.

Just notice that the leak starts when you keep open the language select menu for a while yet, and this whatever your actual/new chosen language is.

Also, the ship market tab is not affected (does not use decimal separator, but space as thousand separator is displayed correctly)

MADE EVEN WORSE?

As mentioned above, this has been displayed correctly in Version 20191117, now there are also question marks and data are written to the swap partition:

@Bodasey please remember to use the <details> tag and code formatting via wrapping your log in three backticks (```) to keep this issue from becoming unmanageable.

@Web-eWorks I took the liberty to edit his post.

Does this mean you're on the master branch? The fix hasn't been merged yet, and is only available on my fork: https://github.com/vakhoir/pioneer/tree/bugfix/font_bake_memory_leak

It should fix both the question marks and the memory leak (although a backup font is likely to be used, since ImGui doesn't detect a character that should be handled by the font).

Yeah, this is a PiGui bug. The version you had previously didn't have the ship market ported to PiGui yet, so that view was still fine.
