[1] gdb reports SIGSEGV, Segmentation fault in tex_hashpairs () [2] size of debug executable
by Graham Douglas 17 Nov '12

Hi nder Windows Vista, latest r4485 build of LuaTeX. I'm trying to use tex.hashtokens(), following the example in the manual I placed the following code into a file called hash.tex === hash.tex ==== \directlua{ for i,v in pairs (tex.hashtokens()) do print(i) end } =============== Running hash.tex under Plain TeX (with the following additions to the Plain format = "lplain") \input plain \directlua {tex.enableprimitives('', tex.extraprimitives())} \pdfoutput=1 I experience a "crash" in LuaTeX. Note: I rebuilt lplain.fmt before running the code Here's the gdb session info: c:\MinGW\bin\gdb.exe g:\luatexlatest\build\texk\web2c\luatex.exe GNU gdb (GDB) 7.1 Copyright (C) 2010 Free Software Foundation, Inc.

Using gdb, if I run rbreak, gdb reports huge numbers of functions with <function, no debug info> Has there been a change to the build process which is resulting in debug info not being included for many hundreds of functions? Best Graham

Building LuaTeX under Windows using the Netbeans IDE [hope not too off-topic]
by Graham Douglas 12 Nov '12

12 Nov '12

Dear All Apologies in advance if this is too off-topic for the list. For a couple of years I've been building LuaTeX under Windows using MSYS/MinGW --- simply running build.sh from the shell. Works well. However, I would really like to use an IDE to step through code and understand more about the source code of LuaTeX. I'm accustomed to using Visual Studio but I also just discovered the Netbeans IDE http://netbeans.org/ It's particularly interesting because it lets you checkout an SVN repository and import it straight into the IDE. I've managed to do that for the LuaTeX repository, but that's as far as I get. Before I spend too much time trying to create a working build process with Netbeans, I was wondering if anyone else has tried this route? If it could be made to work it could create a really nice envionment for building/exploring LuaTeX, especially on Windows. I readily confess to a serious lack of knowledge in Linux-based build processes so I would be very grateful for any advice. If I can get it working I'll write it up on my blog (or elsewhere?) for others to share --- but I'll need some help to get going, or advice that it can't be done. Many thanks in advance. Cheers Graham

Memory leak in string.explode()?
by Reinhard Kotucha 11 Nov '12

11 Nov '12

Dear Sirs, please try this file: ----------------------------------------------------------- #! /usr/bin/env texlua --*- Lua -*- local testfile=('testfile') local use_lpeg=false function split (s, sep) sep = lpeg.P(sep) local elem = lpeg.C((1 - sep)^0) local p = lpeg.Ct(elem * (sep * elem)^0) return lpeg.match(p, s) end fh=assert(io.open(testfile, 'r')) while true do local line, rest = fh:read(2^13, '*line') if not line then break end if rest then line = line..rest end if use_lpeg then local tab = split(line, '\n') else local tab = line:explode('\n') end end fh:close() ----------------------------------------------------------- Reading the file into memory this way is extremely fast and efficient in regard to memory consumption. I have to split the string "line" into lines. This can be done either by string.explode() or split(). When I use the lpeg based function split(), everything is fine, though it's slower than string.explode(). But when I use string.explode(), I see in xosview that memory consumption is steadily growing while the program is running. Regards, Reinhard -- ---------------------------------------------------------------------------- Reinhard Kotucha Phone: +49-511-3373112 Marschnerstr. 25 D-30167 Hannover mailto:reinhard.kotucha@web.de ---------------------------------------------------------------------------- Microsoft isn't the answer. Microsoft is the question, and the answer is NO. ----------------------------------------------------------------------------
