mod_php vs context: tight loop
by Brendan Jurd 03 Jan '12

03 Jan '12

Hello list, I have a PHP application which generates documentation on the fly with context. This has been working really well, but I am now testing deployment on a new server with a more recent version of context, and it seems to be somehow getting itself into a tight loop. When I run texexec via the mod_php apache module, the command never returns, and `ps ax` shows the following: 9709 ? S 0:00 sh -c texexec --check 2>&1 9710 ? S 0:00 /bin/sh /usr/bin/texexec --check 9711 ? R 9:59 /usr/bin/texlua /usr/bin/mtxrun --usekpse --execute texexec --check `top` shows the mtxrun process eating 99.9% CPU. Attaching an strace to this process, once it is underway, shows no output. My test script is as follows: <?php $result = null; system("texexec --check 2>&1", $result); print $result . "\n"; ?> When this same test script is run directly from the command line with `php5 -f test.php`, it works as expected and outputs the following: MTXrun | kpse fallback with progname 'context' initialized in 0.01 secondsTeXExec | current distribution: web2c TeXExec | context source date: 2010.07.30 11:35 TeXExec | format path: . /root/.texmf-config/web2c/luatex /root/.texmf-var/web2c/luatex /root/texmf/web2c/luatex /etc/texmf/web2c/luatex /var/lib/texmf/web2c/luatex /usr/local/share/texmf/web2c/luatex /usr/share/texmf/web2c/luatex /usr/share/texmf-texlive/web2c/luatex /root/.texmf-config/web2c /root/.texmf-var/web2c /root/texmf/web2c /etc/texmf/web2c /var/lib/texmf/web2c /usr/local/share/texmf/web2c /usr/share/texmf/web2c /usr/share/texmf-texlive/web2c TeXExec | start of analysis TeXExec | end of analysis TeXExec | TeXExec | TeXExec | version 6.2.1 - 1997-2009 - PRAGMA ADE/POD 0 Using --timeout=30 in the arguments to texexec makes no difference; mtxrun nonetheless runs forever until it is signalled. It seems that this must be down to some kind of difference in Apache's execution environment -- I don't see any other way to explain the same PHP code working in cli and failing in mod_php, even when running as the same user. But what possible environmental factor could lead to mtxrun freaking out like this? I'm hoping someone on this list may be able to point me in the right direction. This server is a VZ instance running under proxmox, with the following relevant ubuntu packages installed (per the 'natty' release): context 2010.07.30-1 libapache2-mod-php5 5.3.5-1ubuntu7.3 apache2 2.2.17-1ubuntu1.4 -- Regards, Brendan Jurd Software Engineer Achieve, Corp brendan.jurd(a)achievecorp.com.au

bibliography: current status, Wiki page Bibliography, [[error 2]] and bibltx
by Paul Menzel 10 Dec '11

Dear ConTeXt folks, I am trying to use the module bib, but I only get [[error 2]] displayed. I am following the Wiki page Bibliography [1], which suggests the following example (adapted by me). \usemodule[bib] \usemodule[bibltx] \setupbibtex[database=sample] \setuppublications[numbering=yes] % Show reference numbers in the generated list. \starttext As \cite[hh2010b] already indicated, bibtex is a \LaTeX-centric program. \completepublications \stoptext I copied the file `sample.bib` @STRING{hh = {Hans Hagen}} @ELECTRONIC{hh2010, author = hh, year = {2010}, title = {Metafun. \CONTEXT\ mkiv}, url = {http://www.pragma-ade.nl/general/manuals/metafun-s.pdf}, } @ARTICLE{hh2010a, author = hh, title = {The Font Name Mess}, journal = {MAPS}, year = {2010}, volume = {40}, pages = {2-8}, keywords = {context}, } @ARTICLE{hh2010b, author = hh, title = {Grouping in Hybrid Environments}, journal = {MAPS}, year = {2010}, volume = {40}, pages = {67-71}, keywords = {context}, } @BOOK{Eijkhout1991, title = {\TeX\ by Topic. A \TeX nician's Reference}, publisher = {Addison-Wesley}, year = {1991}, author = {Victor Eijkhout}, address = {London}, keywords = {general}, } from the bib module to the directory. Unfortunately I only get »[[error 2]]« displayed. Please find all files attached. Regarding `bibltx` the bib manual does also contain it [2][3]. Searching the Wiki for it, it says that it was dropped in version 2006.04.06 [4].

terrible png placement
by Hans van der Meer 03 Dec '11

03 Dec '11

Something terrible must be done to png pictures, either in ConTeXt or in luatex. I have the following minimal sample code and picture. I include the png for those who want to check. % Test png addition. \starttext Place png figure.\par \placefigure{Test figure}{\externalfigure[test.png]} \stoptext Without the png-picture it makes an 8KB pdf. But with the png-picture the pdf swells to 1.8MB. And that for a png-picture of only 48KB. Moreover making a zip of all this stuff brought the size back to 110KB. In the log: ConTeXt ver: 2011.11.04 14:15 MKIV fmt: 2011.11.10 int: english/english mkiv lua stats > graphics processing time - 0.001 seconds including tex, 1 processed images What is done with the png and can it be remedied? This swelling up of small picture to such enormous proportions makes the inclusion of png-picture nearly impossible, at least impractable. Hans van der Meer

At the start of the contents is an "outer reference" inside the project files an "inner reference". The outer one can be reached both from the outside as well as from the inside of the project files. The colouring of the links show it too. Yhe inner reference does not show up, instead the log shows: > > references > start problematic references > unknown > 2: [part2][label:1] > references > stop problematic references > > But I do not know enough of the referencing mechanism to interprete it. > Hope you can nail the problem, either with my doing or something within ConTeXt. It’s a bug (maybe wrong default settings) which was introduced with Idris request to have lists which are local to a component, when you refer to the label with the name of the component as prefix (\getreference[text][part1:label:1]) the text is shown.

no color with interaction and reference format
by Stefan Müller 02 Dec '11

02 Dec '11

Hi list, when I am using reference formats to put text in front of my text references, I get no color. Please see the following minimal example \setupinteraction[state=start] \definereferenceformat[insec][text=section~] \starttext \section[mylabel]{A Section} A Reference to \in{section}[mylabel] and \insec[mylabel]. \stoptext On my machine only the first reference is red (aka colored), but I think both should be, as it was some betas ago. Is this a bug or has the interface changed? I'm using standalone 20111125 21:29 MkIV. Thanks in advance! Stefan

Why does the oldstyle numerals switch, \os, also switch off m-dashes?
by Pavneet Arora 01 Dec '11

01 Dec '11

I enclose a minimal example as well as the output. It would seem that the \os causes the m-dash to come out as three hyphens. Is this the expected behaviour? advTHANKSance. -- ----- - Pavneet Arora

Escaping a special character in a MetaPost figure within a ConTeXt document fails
by Raymond LeClair 01 Dec '11

01 Dec '11

I have escaped the '#' character in the usual way, using a backslash, as '\#' in a btex...etex picture as part of a MetaPost figure created within a ConTeXt document, but the escaped character still causes the ConTeXt processing to fail. Here is an example... \pdfminorversion=5 \definepapersize[LG1][width=4.25in,height=6.875in] \definepapersize[LP1][width=4.25in,height=6.875in] \setuppapersize[LG1][LP1] \definelayout[frontmatter] [topspace=0.222222222222in,header=0.555555555556in,height=6.43055555556in,footer=0.694444444444in, backspace=1.05555555556in,width=2.86111111111in,location=middle, leftmargindistance=0.222222222222in,rightmargindistance=0.222222222222in, leftmargin=0.833333333333in,rightmargin=0.111111111111in] \definefont[TitleFont][Serif sa 3.5] \definecolor[TransparentWhite][b=1,t=0,a=1] \def \FrontMatterTitle { \startreusableMPgraphic{frontmattertitle:\overlaywidth:\overlayheight} matter_paper_width := 4.25in; matter_paper_height := 6.875in; front_left_margin := 0.388888888889in; top_margin := 0.347222222222in; draw (0, 0)--(matter_paper_width, matter_paper_height) withpen pencircle scaled 1bp withcolor white; picture titleText; % == HERE IS THE SOURCE OF THE PROBLEM == titleText := btex {\vbox{\hsize 2.72916666667in \baselineskip 38.0pt \setupalign[flushleft,hyphenated,verytolerant] \TitleFont THE BEGINNINGS OF \#BOOM}} etex; labeloffset := 0bp; label.lrt(titleText, (front_left_margin, matter_paper_height - top_margin)); \stopreusableMPgraphic \reuseMPgraphic{frontmattertitle:\overlaywidth:\overlayheight} } \defineoverlay[frontmattertitle][\FrontMatterTitle] \starttext \setuplayout[frontmatter] {\TransparentWhite\title{...}} \setupbackgrounds[page][background={{frontmattertitle}},state=repeat] {\TransparentWhite\midaligned{...}} \stoptext
