vsftpd build script

Hola mi amigos,

I am trying to create a Slackware package from vsftpd 2.0.3 source and would like a little help on modifying the build script in the current tree of Slackware. I have been using Slackware for a while now, but have just recently started to learn scripting and how to correctly use build scripts to create my own packages.

The current build script for vsftpd 2.0.1:

Code:

#!/bin/sh

CWD=`pwd`

TMP=${TMP:-/tmp}

PKG=$TMP/package-vsftpd



VERSION=2.0.1

ARCH=${ARCH:-i486}

BUILD=1



if [ ! -d $TMP ]; then

  mkdir -p $TMP

fi

rm -rf $PKG

mkdir -p $PKG

cd $TMP

rm -rf vsftpd-$VERSION

tar xzvf $CWD/vsftpd-$VERSION.tar.gz

cd vsftpd-$VERSION

find . -perm 777 -exec chmod 755 {} \;

find . -perm 664 -exec chmod 644 {} \;

chown -R root.root .

zcat $CWD/vsftpd.builddefs.diff.gz | patch -p1 --verbose

zcat $CWD/vsftpd.conf.diff.gz | patch -p1 --verbose

make -j3

mkdir -p $PKG/usr/sbin

cp vsftpd $PKG/usr/sbin

chmod 755 $PKG/usr/sbin/vsftpd

chown -R root:bin $PKG/usr/sbin

strip --strip-unneeded $PKG/usr/sbin/vsftpd

mkdir -p $PKG/usr/man/man{5,8}

cat vsftpd.conf.5 | gzip -9c > $PKG/usr/man/man5/vsftpd.conf.5.gz

cat vsftpd.8 | gzip -9c > $PKG/usr/man/man8/vsftpd.8.gz

mkdir -p $PKG/etc

cat vsftpd.conf > $PKG/etc/vsftpd.conf.new

mkdir -p $PKG/etc/logrotate.d

zcat $CWD/vsftpd.log.gz > $PKG/etc/logrotate.d/vsftpd.new

mkdir -p $PKG/usr/share/empty

mkdir -p $PKG/home/ftp

mkdir -p $PKG/usr/doc/vsftpd-$VERSION

cp -a \

  AUDIT BENCHMARKS BUGS COPYING COPYRIGHT Changelog EXAMPLE FAQ \

  INSTALL LICENSE README* REFS REWARD SECURITY SIZE SPEED TODO TUNING \

  $PKG/usr/doc/vsftpd-$VERSION

mkdir -p $PKG/install

cat $CWD/slack-desc > $PKG/install/slack-desc

zcat $CWD/doinst.sh.gz > $PKG/install/doinst.sh



cd $PKG

makepkg -l y -c n $TMP/vsftpd-$VERSION-$ARCH-$BUILD.tgz

Do I only need to change the version/build, or what? And maybe a good explanation of what is going on in that code. :D

You need the vsftpd.builddefs.diff.gz, vsftpd.conf.diff.gz, slack-desc
and doinst.sh.gz files, then change the version number and all should
go well.

For the explanation, as the script does a bunch of stuff,
could you ask for a particular part ?

first thing you'd wanna do is just replace the source tarball in the directory and then change the "VERSION=2.0.1" to "VERSION=2.0.3"... then run it like that and take note of any errors you get... i see there's a couple patches in the build directory so you'd probably have to make a couple adjustments, although that's not always the case... if the new version is just a bugfix release you might be just fine, but i haven't looked at the vsftpd changelog and also i haven't looked at those slackware patches so i'm not sure...

It seems as though the patches are nothing more than a way to enable different features of vsftpd. The links to the files are:

http://slackware.mirrors.pair.com/sl...lddefs.diff.gz

http://slackware.mirrors.pair.com/sl...d.conf.diff.gz

So i should be able to download them and modify it to my specifications and all will be well.

The part of the script i wasn't sure of was:

Code:

zcat $CWD/vsftpd.builddefs.diff.gz | patch -p1 --verbose

zcat $CWD/vsftpd.conf.diff.gz | patch -p1 --verbose

Although, i have looked up what the program is, i still don't understand why i shouldn't just use patch command to complete this task.

zcat is like cat except it gunzips the file before cating it...

it's the same as doing a "gunzip -c"...
