Thread: BSD gettext
http://www.postgresql.org/~petere/gettext.html This is a compilation of the BSD-licensed gettext tools from NetBSD plus some of my own code, put into a (hopefully) portable package, intended to be evaluated for possible use in PostgreSQL. Give it a try if you're interested. I've already tried it on FreeBSD, Linux, and Unixware, so don't bother with those. I feel that this is ready to go. NetBSD is using it in production as a GNU gettext replacement, even for large packages. The .mo file format is pretty simple actually, so if issues came up we could tackle them ourselves. As for portability, the fanciest feature it uses is mmap(), but only to map a real file into memory to read it there. The missing functions (strlcat, strlcpy, strsep) I've worked around with autoconf, the rest looks all like basic POSIX stuff. So I suppose if this looks okay I will start trying to work out how we can use this for PostgreSQL. -- Peter Eisentraut peter_e@gmx.net http://funkturm.homeip.net/~peter

I tried on Digital Unix 4.0f, using Digital cc: Making all in gettext make[2]: Entering directory `/tmp/bsd-gettext-0.0/gettext' cc -DHAVE_CONFIG_H -I. -I. -I.. -DLOCALEDIR=\"/tmp/gettext/share/locale\" -I ../libintl -g -c gettext-main.c cc: Severe: ../config.h, line 36: Cannot find file <unistd.h> specified in #include directive.

On HPUX 10.20:
make[2]: Entering directory `/home/tgl/pgsql/bsd-gettext-0.0/libintl'
/bin/sh ../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.. -g -O2 -c gettext.c
gcc -DHAVE_CONFIG_H -I. -I. -I.. -g -O2 -c gettext.c -o gettext.o
gettext.c: In function `mapit':
gettext.c:313: `MAP_FAILED' undeclared (first use in this function)
gettext.c:313: (Each undeclared identifier is reported only once
gettext.c:313: for each function it appears in.)
gettext.c: In function `unmapit':
gettext.c:442: `MAP_FAILED' undeclared (first use in this function)
make[2]: *** [gettext.lo] Error 1
The HPUX man page for mmap documents its failure return value as "-1",
so I hacked around this with
#ifndef MAP_FAILED
#define MAP_FAILED ((void *) (-1))
#endif
whereupon it built and passed the simple self-test you suggested.
However, I think it's pretty foolish to depend on mmap for such
little reason as this code does. I suggest ripping out the mmap
usage and just reading the file with good old read(2).

I'm prepared to do that if mmap doesn't work for someone, but I'm not eager to fork the code without proven breakage. -- Peter Eisentraut peter_e@gmx.net http://funkturm.homeip.net/~peter

The reason mmap() is faster than read() is that it can avoid copying data to the place you specify. read() can "use mmap() internally" only in cases rare enough to hardly be worth checking for. Stdio is often able to use mmap() internally for parsing, and in glibc-2.x (and, I think, on recent Solarix and BSDs) it does. Usually, therefore, it would be better to use stdio functions (except fread()!) in place of read(), where possible, to allow this optimization. Using mmap() in place of disk read() almost always results in enough performance improvement to make doing so worth a lot of disruption. Today mmap() is used heavily enough, in important programs, that worries about unreliability are no better founded than worries about read(). Nathan Myers ncm@zembu.com
