Damage when drawing a cylinder from pdflatex in versions after 2.53

[zarniwhoop73]

I have not been looking at results from my test documents with enough care. The following MWE produced a boring cylinder up to v2.53. In v2.54 it lost a rectangular part in the top, and also lost the colour, in 2.55 the colour was restored but not the top, similar result through to 2.62. In 2.63, 2.64 and current git the top or far side is restored, but a bigger chunk is taken out from the nearest side and another chunk is missing from the top right corner which eventually drew my attention to it.

`
\documentclass[12pt]{article}

\usepackage{asymptote}

\begin{document}

\begin{asydef}
import three;
\end{asydef}

\begin{center}
\begin{asy}cylinder:
pdflatex cylinder.tex
asy -V cylinder-*.asy
pdflatex cylinder.tex
pdflatex cylinder.tex

settings.render=16;
size(15cm,0);

draw(unitcylinder, red+opacity(.3));

\end{asy}
\end{center}

\end{document}
`
I use a Makefile withtwo runs of pdflatex after asy because it complained it needed to be rerun :

`
cylinder:
pdflatex cylinder.tex
asy -V cylinder-*.asy
pdflatex cylinder.tex
pdflatex cylinder.tex

I now see that although current git reported the version as 2.65git, the install exited after 'makeinfo --no-warn --no-split ../asymptote' in doc/png' without any messages but presumably with non-zero status.

This is a problem with the tiling code; I will look into it. For the record, here's a minimal example:

 import three;
settings.render=4;
settings.tex="pdflatex";
size(15cm,0);
draw(unitcylinder,red);

For now, try using a lower settings.render value.

The makeinfo error likely indicates that your version of makeinfo is obsolete.
This version of makeinfo works fine:

makeinfo --version

I am using a newer makeinfo on the machine where I tried 2.65git
$makeinfo --version
texi2any (GNU texinfo) 6.7

As to a lower settings.render in my example, with 2 it works fine, with 4 it does not.

I now cannot recreate the info problem when manually building and installing, although the installed info file definitely says it is still 2.64 (I went through the versions in order for the main issue). Maybe a weird one-off problem.

"although the installed info file" : although the original installed info file

The tiling bug reported here is fixed in 1566850.

[johncbowman]

Actually, the problem wasn't with the tiling code after all; it was due to a typo from 2015
in bf3be19. The proper fix is in 3542857 and the upcoming 2.66 release.
