A few bugs with the web site
by Reuben Thomas 06 Jun '14

06 Jun '14

0. [Meta-bug]: please make it easier to report bugs with the web site. I had to sign up for this mailing list; many people may not want to merely to report things like: 1. On roadmap.html, "cummunity" → "community" 2. Under "Objectives and Status", roadmap.html talks about already-released versions in the future tense. Please fix this. 3. faq.html: "learned us" should be "taught us" (this changed in English in the last few hundred years, but the web page may predate that change :) ) 4. sponsoring.html: "Thanks to this sponsoring" → "Thanks to this sponsorship" 5. swiglib.html: "Januari" → "January"; "Februari" → "February" 6. languages.html: "persistant" → "persistent"; "openess" → "openness" 7. index.html "projects main" → "project's main"; "as stable an" → "as stable and" -- http://rrt.sc3d.org

[PATCH] Bug 487 (negative protrusion)
by Dominic Jänichen 24 Apr '14

24 Apr '14

I was affected by bug 487 using microtype's protrusion=true. Digging around, I found that the error lies in round_xn_over_d (pdfgen.w). Please find attached a patch to correct the issue. Details: round_xn_over_d calculates (x*n / d). It casts to unsinged integers, guarding the sign of x but not of n. Negative protrusions, however, are fed into n... Aside: I wonder whether its method to calculate still makes sense, given modern compiler optimizations. What about something along the lines of..? unsinged long long t = x * n; t = t % d; if (t > INT_MAX) arith_error = true; return (scaled) t; Dominic --- a/luatexdir/pdf/pdfgen.w 2014-04-23 10:46:24.485686773 +0200 +++ b/luatexdir/pdf/pdfgen.w 2014-04-23 10:49:03.354059350 +0200 @@ -751,13 +751,15 @@ @c scaled round_xn_over_d(scaled x, int n, unsigned int d) { - boolean positive; /* was |x>=0|? */ + boolean positive = true; /* was |x>=0|, |n>=0| ? */ unsigned t, u, v; /* intermediate quantities */ - if (x >= 0) { - positive = true; - } else { + if (x < 0) { + positive = !positive; x = -(x); - positive = false; + } + if (n < 0) { + positive = !positive; + n = -(n); } t = (unsigned) ((x % 0100000) * n);//printf("t=%d\n",t); u = (unsigned) (((unsigned) (x) / 0100000) * (unsigned) n + (t / 0100000));//printf("u=%d\n",u);
