Re: [Dev-luatex] Fatal crash with LuaTeX if an encoding file is missing

Hi Graham, Graham Douglas wrote: > Hi Taco > > See attached screenshot. This is what triggered me to think it was > more than just a fatal error? Maybe not then. In the case of fatal errors (of the kind below, that remove the pdf document as well) luatex will call 'exit()' with the return code 'EX_SOFTWARE' if kpathsea debugging is off, or with 'abort()' if kpathsea debugging is on. The first form is a pretty normal exit, the second form is an explicit forced crash (done because this can be useful when debugging). Therefore you should only get a popup with kpathsea debugging turned on (via the command line --kpathsea-debug= parameter, or via a global KPATHSEA_DEBUG environment setting). Well, unless windows is not behaving like unix (which is quite definitely possible, I don't know *that* much about windows). Best wishes, Taco

Fatal crash with LuaTeX if an encoding file is missing
by Graham Douglas 05 Apr '10

05 Apr '10

Hi I have experienced a fatal crash with LuaTeX if an encoding file is missing: I am using debug versions (built with --nostrip) Reproducible in This is LuaTeX, Version beta-0.53.0-2010032719 This is LuaTeX, Version beta-0.60.0-2010040417 --- both are debug versions compiled from source All you need to do is rename the encoding file to something different mentioned in pdftex.map and the crash is reproducible every time. [1{c:/msys/1.0/trunk/build/texk/fonts/map/pdftex.map}] ) (see the transcript file for additional information) !LuaTeX error: cannot find encoding file for reading ==> Fatal error occurred, no output PDF file produced! Please let me know anything else I can do which will help track this down. I have GNU's gdb installed and would be happy to do whatever I can to help. Also, if this is not the right way to report bugs/issues do please let me know and I'll follow the correct procedures. Best wishes Graham

Luatex 0.60.0 announcement
by Taco Hoekwater 05 Apr '10

05 Apr '10

Hi, I have just uploaded the archives for a new luatex release, 0.60.0. This release starts a new chain of stable beta's, and will be the version included in this year's TeXLive. New features: * os.name now knows about CYGWIN (from Elie Roux) * Internal handling of direction specifiers is faster now. * Each glyph node now has three new virtual read-only fields: width, height, and depth (values in scaled points, of course) * There are new functions node.protrusion_skipable() and tex.badness() (useful for paragraph breaking in lua) * Also new: tex.linebreak(). See the manual for details. * All lua errors now report file and line numbers to aid in debugging. * Import of metapost 1.211. * pdf.pdfcatalog will be replaced soon by the new pdf.catalog pdf.pdfinfo will be replaced soon by the new pdf.info pdf.pdfnames will be replaced soon by the new pdf.names pdf.pdftrailer will be replaced soon by the new pdf.trailer * pdf.pdfmapfile and pdf.pdfmapline are replaced by the new pdf.mapfile() and pdf.mapline() functions. (a function interface fits these parameters better because they never return anything). * New read-write lua variables: pdf.pageattributes, pdf.pageresources, pdf.pagesresources * getluatexsvnversion.sh now correctly detects git-svn and still manages to find a valid SVN revision number (from Patrick Gundlach) * Many of the source files have been converted to CWEB. Bug fixes: * GNU libtool is now used to solve the various technical issues with dynamic loading of lua modules. * Error detection in scan_integer_part was wrong due to missing initialization of OK_so_far (spotted by Javier Mugica) * Synctex was broken in 0.51-0.52. * \lastlinefit was broken since ... well, nearly forever. * Reading of binary files with length zero was broken. * Trapping of unitialized rules (this was for sloppily created rule nodes from lua) * pdf.immediateobj('streamfile') was broken on 64-bit platforms. * tex.linebreak did not take the given left and right skip, but instead used the current TeX-side values (bug #356). * the found 'MAKE' command in build.sh is now fed into configure to fix problems with that not finding GNU make even when it is actually installed. * dofile(<nil>) and loadfile(<nil>) in batch mode now give an error and continue instead of pointlessly waiting for user input. * Reverted commit #3417 (the buildpage experiment) as it causes bad things to happen when items are waiting during page breaks. * Overrule loaders[4] in --safer mode, make require() behave closer to normal lua 5.1, and add some nicer error messages (based on an email and patches from Manuel Pegourie-Gonnard) * Added an extra sanity check for GDEF loading in luafontloader, based on a crash caused by Linux' AkaashNormal.ttf. The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/gf/project/luatex/ You could also check out the sources via anonymous svn: svn co http://foundry.supelec.fr/svn/luatex/tags/beta-0.60.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

Luatex 0.40-0.60 delta
by Taco Hoekwater 04 Apr '10

04 Apr '10

Hi, As some people may be interested in the differences between the luatex in TL 2009 and the one in the upcoming TL 2010, so I compiled a list of all non-bugfix changes between 0.40.7 and 0.60.0. Please let me know if I missed something ... General changes: * Many of the source files have been converted to CWEB. * There is now support for revision numbers in the banner again. * The horizontal mode nodes that are added to lines during line breaking now inherit the attributes from the first and last node inside the created line. * All lua errors now report file and line numbers to aid in debugging. * Luatex can now optionally use kpathsea to find lua require() files. * The print precision for small numbers in lua code (tostring) has been improved. Embedded libraries and other third-party inclusions: * Metapost is now at version 1.211. * New synctex code imported from TeXLive. * Libpng is now at version 1.2.40. * The lua file from the luamd5 library (which provides the md5.hexsuma() function) is now embedded in the executable. * The Lua coroutine patch (coco) is now disabled on linux powerpc architectures (because it caused crashes) * Luatex now has support for dynamic loading of external compiled lua libraries. Font related: * The backend message "cannot open Type 1 font file for reading" now reports which Type1 font file it was looking for. * It is no longer possible for fonts from embedded pdf files to be replaced by / merged with the document fonts of the enveloping pdf. * Support for Type3 .pgc files has been removed. * The variables <metrics>.Mathconstants.FractionDelimiterSize and <metrics>.Mathconstants.FractionDelimiterDisplayStyleSize are added to the font table. This allows proper setting of the size parameters for TeX's ...withdelims math primitives. * Artificially slanted or extended fonts now work via the pdf text matrix so that it now also works for non-Type1 fonts. The lua <metrics>.slant and .extend font keys are now obeyed in all cases. * A change to the relative ordering inside font name discovery for use by the backend: now it tries <f>.psname first, as that is much less likely to contain spaces. * For ttc fonts, now the used subfont name and its index id are printed to the terminal, and if the backend cannot find a ttc subfont, the run is aborted. * It is now possible to use Apple dfont font files. * There is a new allowed key in the table that is returned by lua-loaded fonts: <f>.psname. This value should be set to the original PostScript font name of the font. Fonts inside dfont and ttc collections are fetched using this field * lua-loaded fonts now support a 'nomath' key to speed up loading the lua table. * The loading speed of large fonts via the fontloader library, and the inclusion speed for subsetting in the backend have both been improved. 'TeX'-side extensions: * Two new token lists are provided: \pdfxformresources and \pdfxformattr, as an alternative to \pdfxform keywords. * \input and \openin now accept braced filenames. * The \endlinechar can now be set to any value between 0 and 127. * The new primitives \aligntab and \alignmark are aliases for the use of & and # in alignments. * \pdfrefxform [width <dimen>] [height <dimen>] [depth <dimen>] <formref> scales a form object; similar principle as with \pdfximage: depth alone doesn't scale, it shifts vertically. * \pdfrefximage [width <dimen>] [height <dimen>] [depth <dimen>] <imageref> overrules settings from \pdfximage for this \pdfrefximage call only * \pdfobj now has an extra optional keyword: 'uncompressed', which forces the object to be written to the PDF in plain text (see the manual for the exact details). * \latelua is now allowed inside leaders. * The new primitive \gleaders provides 'globally aligned' leaders. * The \pdfcompresslevel is now effectively fixed as soon as output to the pdf file has occurred. * Removed obsolete pdftex primitives: \pdfoptionalwaysusepdfpagebox \pdfoptionpdfinclusionerrorlevel \pdfforcepagebox \pdfmovechars * (un-feature): from now on luatex now only handles 4 direction specifiers: TLT (latin), TRT (arabic), RTT (cjk), and LTL (mongolian). The other directions now generate an error. Lua table extensions: * callback table: ** There is a new callback: process_output_buffer ** The callbacks hpack_filter, vpack_filter and pre_output_filter pass on an extra string argument for the direction, when known. * fontloader table: ** fontloader.open() previously cleared some font names that it should not. * font table: ** new function font.id() * kpse table: ** new functions kpse.lookup() and kpse.version() * lfs table: ** new functions lfs.readlink() and lfs.shortname() * node table: ** new function node.vpack() ** new function node.protrusion_skipable() ** new function node.dimensions(). ** new function node.tail() ** Each glyph node now has three new virtual read-only fields: width, height, and depth (values in scaled points) ** node.copy_list() now allows the second (optional) argument to be nil. ** node.hpack() now accepts "cal_expand_ratio" and "subst_ex_font" modifiers. ** node.hpack() and node.vpack() also give back the badness of the box. ** node.copy_list() now allows a second (stop) argument. ** The lua functions node.hpack(), node.vpack() and node.dimensions() now accept an optional direction argument. ** hlist nodes now have a subtype to distinguish hlists generated by the paragraph breaking, explicit \hbox commands, and other sources. ** glue_spec nodes now have an extra field: writable. * os table: ** os.name now knows about CYGWIN and kfreebsd. * pdf table: ** new functions: pdf.mapfile(), pdf.mapline() ** new function pdf.registerannot() ** new functions pdf.obj(), pdf.immediateobj(), pdf.reserveobj() ** new read-write string keys: pdf.catalog, pdf.info, pdf.names, pdf.trailer, pdf.pageattributes, pdf.pageresources, pdf.pagesresources * tex table: ** new function tex.badness() ** new function tex.linebreak() ** new function tex.sp() ** new function tex.tprint() ** new function tex.shipout() ** new sub-table: tex.nest[] (rw access to the semantic nest state).
