Strange code for font_param
by Lars Hamren 15 Nov '16

15 Nov '16

Hi, I found some odd behaviour, arguably a bug or two, when I added bounds checking to _param_base, in struct texfont. As I have fixed this in my own code, this is just FYI. At about line 750 in mlist.w: DEFINE_DMATH_PARAMETERS(math_param_radical_vgap, size_id, (default_rule_thickness(size_id) + (abs(math_x_height(size_id)) / 4)), lvl); default_rule_thickness turns out to be math parameter 8. But at least font 0 (nullfont) has only 7 parameters (according to _font_params). Parameters are Pascal-style (one-based) so there has to be one more element that parameters. Still, parameter 8 is outside the array bounds. But! When reallocating the _param_base array, the set_font_params() allocates not only one, but two, extra elements, so accessing parameter 8 works. The extra extra element is not initialized by set_font_params(), but either it is never actually used, or dynamic memory is zero-filled by default. These bugs are present int 0.95.0. They may or may not be present in later versions. Clarification: by bugs I mean a) accessing outside the logical bounds, and b) not initializing all elements. One quick way to fix it would be to check the parameter number in font_param(), and return 0 if out of bounds.

Strange code in dvigen.w
by Lars Hamren 25 Oct '16

25 Oct '16

Hi, I came across this code in the current luatex trunk: void out_cmd(void) { if ((oval < 0x100) && (oval >= 0)) { if ((ocmd != set1) || (oval > 127)) { if ((ocmd == fnt1) && (oval < 64)) oval += fnt_num_0; else dvi_out(ocmd); } } else { if ((oval < 0x10000) && (oval >= 0)) { dvi_out(ocmd + 1); } else { if ((oval < 0x1000000) && (oval >= 0)) { dvi_out(ocmd + 2); } else { dvi_out(ocmd + 3); if (oval >= 0) { dvi_out(oval / 0x1000000); } else { oval += 0x40000000; oval += 0x40000000; dvi_out((oval / 0x1000000) + 128); oval = oval % 0x1000000; } dvi_out(oval / 0x10000); <---------- Remove? oval = oval % 0x10000; } dvi_out(oval / 0x10000); <---------- oval = oval % 0x10000; } dvi_out(oval / 0x100); oval = oval % 0x100; } dvi_out(oval); } It seems that the same byte gets written twice in some cases (see the arrows). When compiling tlb0735.lvt in the latex test suite, the output is not accepted by e.g. xdvi. I test with 0.95 and texlive. Cheers /Lars

map file record missed in fls file
by Sigitas Tolusis 17 Oct '16

17 Oct '16

Hi, It seems that input-ed map files are not mentioned in the fls file if the --recorder switch is specified on the command line to lualatex. I have tested beta-0.76.0-2013041118 and 1.0.0 luatex versions. Regards, Sigitas Tolušis
