How to make local build DU4 on VM environment

Actions

Create and update the new VM
Prepare environment for creating new zones
Prepare script to get dependencies for components
Create a zone for local repository
Add packages and source files to the local repository

Create the new zone for components building
Build components

1. Create and update the new VM

To create the new VM in vSphere SPB-LABS execute please steps 1-5 from this instruction.

2. Login with root account and prepare environment for zones creation

Create the mountpoint for zones mounting:

root@dilos:~# zfs create -o mountpoint=/zones rpool/zones
root@dilos:~# mkdir /export/builds

2. Add the admin user:

root@dilos:~# useradd -m -g staff admin
root@dilos:~# passwd admin
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully
root@dilos:~# echo "admin ALL=(ALL:ALL) NOPASSWD: ALL" >> /etc/sudoers.d/admin

3. Execute Instruction for NET configuration till the step of zone01 creation.

4. To automate zone creation you can copy this script to create_zone.sh file or execute the following command:

cat > create_zone.sh <<SCRIPT
#!/bin/bash

TYPE_ZONE=\$1
IP=\$2
SER=\$3

cat > \${HOME}/\${TYPE_ZONE}.cmd <<EOT
create
set zonename=\${TYPE_ZONE}
set zonepath=/zones/\${TYPE_ZONE}
set autoboot=false
set ip-type=exclusive
add net
set physical=iz\${SER}
set global-nic=vsw0
add property (name=ip,value="\${IP}.\${SER}")
add property (name=gateway,value="\${IP}.254")
add property (name=netmask,value="255.255.255.0")
add property (name=primary,value="true")
end
add attr
set name=resolvers
set type=string
set value=8.8.8.8
end
add fs
set dir="/export/home/admin"
set special="/export/home/admin"
set type="lofs"
end
add fs
set dir="/export/builds"
set special="/export/builds"
set type="lofs"
end
add fs
set dir="/data/repo"
set special="/data/repo"
set type="lofs"
end
verify
commit
exit
EOT
zonecfg -z \${TYPE_ZONE} -f \${HOME}/\${TYPE_ZONE}.cmd
zoneadm -z \${TYPE_ZONE} install && zoneadm -z \${TYPE_ZONE} boot
echo "127.0.0.1 localhost.\${TYPE_ZONE} \${TYPE_ZONE}" >> /zones/\${TYPE_ZONE}/root/etc/hosts
SCRIPT

Make it executable:

chmod 777 ./create_zone.sh

Now you will be able to run it with the format of ./create_zone.sh <zone-name> <zone-ip-domain> <zone-ip-node> , for example!:

./create_zone.sh zone02 192.168.0 3

3. Prepare script to get dependencies for components.

Create a folder for the local repository and enter it:

mkdir -p /data/repo/pkg
cd /data/repo/pkg

To make the following script workable you have to create the list_component file with a content from here.

Create here a script to obtain dependencies and repository creation. To do this copy please this script to the file, let say, make_repo.sh or execute the following command:

cat > make_repo.sh <<EOT
#!/bin/bash
#DEP_FILE=""
DEP_FILE="req.txt"
LOG_FILE=""
#LOG_FILE="/data/repo/repo.log"
function print_log {
  if [[ "\$LOG_FILE" != "" ]]; then
    echo "\$1" >> \$LOG_FILE
  fi
}
## Loop for get build components dependencies
echo "" > list_to_check
echo "" > final_list
sed -i '/^[ \\t]*\$/d' list_component
echo "" >> list_component
echo "" > temp
if [[ "\$DEP_FILE" != "" ]]; then 
    echo "" > \$DEP_FILE
fi
while read comp; do
  ## Skip empty line
  if [[ "" == "\$comp" ]]; then
    continue
  fi 
  echo -e "\\033[33m =====> Getting depends for \$comp... \\033[0m"

apt-get -R /data/repo/pkg/_tdir update
## Loop for get packages dependencies
while [[ "\$end" != "" ]]; do
  echo "" > temp
  while read comp; do
    ## Skip empty line
    if [[ "" == "\$comp" ]]; then
      continue
    fi
    ## Skip packages that are already checked for dependencies
    res=\$(grep "^[ \\t]*\$comp[ \\t]*\\\$" final_list)
    if [[ "" != "\$res" ]]; then
      continue
    fi
    echo "=====> Getting depends for \$comp..."
    apt-get -R /data/repo/pkg/_tdir install --dry-run \$comp | grep "^Inst " | sed 's/^Inst //; s/ .*\$//' > tmp
    cat tmp >> temp
    ## Add checked package to the list of already checked packages
    echo "\$comp" >> final_list
    if [[ "\$DEP_FILE" != "" ]]; then
      sed "s/^/\$comp:/g" tmp >> \$DEP_FILE
    fi
  done < list_to_check
  ## Remove repeated records from the list
  sort -u temp > list_to_check
  ## Remove empty lines if any
  sed -i '/^[ \\t]*\$/d' list_to_check
  sed -i '/^[ \\t]*\$/d' final_list
  end=\$(cat list_to_check)
  echo "" >> list_to_check
done

sed -i '/^[ \\t]*\$/d' final_list
sort -u final_list > temp
mv -f temp final_list

fi
EOT

Make this file executable:

chmod 777 ./make_repo.sh

If you have to get the error log then put the log name to the string LOG_FILE="" , for example:

LOG_FILE="/export/admin/repo.log"

4. Create a zone for the local repository

Create the new zone and enter it:

cd ~
./create_zone.sh zonerepo 192.168.0 2
zlogin zonerepo

All the following commands are executed in the zonerepo.

Update the /etc/apt/sources.list file:

cat > /etc/apt/sources.list <<EOT
deb http://10.20.50.188/dilos4 du4-unstable main contrib non-free
deb http://10.20.50.188/dilos dg2-unstable main contrib non-free
deb-src http://10.20.50.188/dilos4 du4-unstable main contrib non-free
EOT
apt-get update

Install packets required for working in the zone:

apt-get install reprepro apache2 debhelper dpkg-dev dh-exec apt-rdepends screen -y
ln -s /data/repo /var/www/html/dilos
svcadm enable http
svcs http

Create a folder for repository configuration files:

mkdir -p /data/repo/conf

and create the repository configuration:

echo -n "Codename:  du4-prebuild
Suite:  prebuild
Version: 4.0
Origin: DilOS
Label: DilOS prebuild
Description: DilOS Prebuild Repository
Architectures: solaris-i386 solaris-sparc source
Components: main contrib non-free
##SignWith: default
DebIndices: Packages Release . .gz .bz2 .xz
DscIndices: Sources Release . .gz .bz2 .xz
Contents: . .gz .bz2 .xz
" > /data/repo/conf/distributions

5. Add packages and source files to the local repository

cd /data/repo/pkg
./make_repo.sh
exit

Creating of the local repository can take a long time. So, you can run it with the screen utility.

Running with the screen utility

If you are connected by SSH and would like to turn off SSH session or even temporary turn off your computer, then you have enter the following command for tests running:

screen ./make_repo.sh

Then you can in any time press Ctrl-A d and after that close your SSH session.

When you would like to get back, login again to SSH please and enter the command:

screen -r

6. Create the new zone for components building

Create the new zone and enter it:

./create_zone.sh zonebld 192.168.0 3
zlogin zonebld

All the following commands are executed in the zonebld.

Prepare the zone for components building. To do this please copy this script to, let say, the prepare.sh file or execute the following command:

cat > prepare.sh <<EOT
#!/bin/bash
WORKSPACE=/export/home/du4
apt-get clean
apt-get autoclean
apt-get remove libiconv-dev -y
apt-get install -y  build-essential git dpkg-dev screen gmake
cp /etc/apt/sources.list /etc/apt/sources.list.bak
echo "" > /etc/apt/sources.list
echo "deb [trusted=yes] http://192.168.0.2/dilos du4-prebuild main contrib non-free" >> /etc/apt/sources.list
echo "deb-src [trusted=yes] http://192.168.0.2/dilos du4-prebuild main contrib non-free" 2>/dev/null >> /etc/apt/sources.list
cp /etc/apt/sources.list /etc/apt/sources.list.dev
apt-get update -y
#test -f /var/lib/dpkg/lock && rm -f /var/lib/dpkg/lock
#test -f /var/cache/apt/archives/lock && rm -f /var/cache/apt/archives/lock
#dpkg --configure -a
rm -rf \${WORKSPACE} && mkdir -p \${WORKSPACE}
apt-get upgrade -y
env DEBIAN_FRONTEND=noninteractive apt-get install -y -f
env DEBIAN_FRONTEND=noninteractive apt-get install -y openssh-server
EOT

Make it executable and run:

chmod 777 ./prepare.sh
./prepare.sh

7. Build components

Copy this script to, for example, thebuild_all.sh file or execute the following command:

cat > build_all.sh <<EOT
#!/bin/bash
BLD_PARALLEL="4"
WORKSPACE=/export/home/du4
#STOP_ON_ERROR=1
STOP_ON_ERROR=0
#GCC_COMPILER="gcc-10"
GCC_COMPILER=""
# Build a component: \$1 - component name, \$2 - stop-on-error flag
function build_component {
  BLD_RESULT="/data/repo/du/\$1"
  test -z "\$1" && exit 1
  test -d \${BLD_RESULT} && rm -rf \${BLD_RESULT}
  DEB_BUILD_OPTIONS="nocheck notest parallel=\${BLD_PARALLEL}"
  export DEB_BUILD_OPTIONS
  test -d \${WORKSPACE}/\$1 && rm -rf \${WORKSPACE}/\$1
  mkdir -p \${WORKSPACE}/\$1
  cd \${WORKSPACE}/\$1
  echo "====================== \$1 ======================"  | tee berror.log
  if [[ \$2 -eq 0 ]]; then
    apt-get build-dep -y \$1 >> berror.log || return 0 2>&1
    apt-get source --compile \$1 >> berror.log || return 0 2>&1
  else
    apt-get build-dep -y \$1 >> berror.log || return 1 2>&1
    apt-get source --compile \$1 >> berror.log || return 1 2>&1
  fi
  mkdir -p \${BLD_RESULT}
  cp -ax *.deb \${BLD_RESULT}/ || exit 1
  cp -ax *.changes \${BLD_RESULT}/ || exit 1
  cp -ax *.buildinfo \${BLD_RESULT}/ || exit 1
}
if [[ "\$GCC_COMPILER" != "" ]]; then
  echo "====================== Building GCC ======================"
  build_component \$GCC_COMPILER 1
  if [[ \$? -eq 1 ]]; then
    exit 1
  fi
  dpkg -i \$WORKSPACE/\$GCC_COMPILER/*.deb
fi
while read COMP; do
  if [[ "" == "\$COMP" ]] || [[ "\$GCC_COMPILER" == "\$COMP" ]]; then
    continue
  fi
  build_component \$COMP \$STOP_ON_ERROR
  if [[ \$? -eq 1 ]]; then
    exit 1
  fi
done < /data/repo/pkg/list_component
EOT

If you’d like stop process on the first error, put 1 the STOP_ON_ERROR variable STOP_ON_ERROR=1. In other case it will build all components one-by-one regardless of errors. And in every component folder theberror.log file will be created, where build errors will be stored.

Make it executable and run:

chmod 777 ./build_all.sh
./build_all.sh

The building process can take a long time. So, you can run it with the screen utility.

Running with the screen utility

If you are connected by SSH and would like to turn off SSH session or even temporary turn off your computer, then you have enter the following command for tests running:

screen ./build_all.sh

Then you can in any time press Ctrl-A d and after that close your SSH session.

When you would like to get back, login again to SSH please and enter the command:

screen -r

If you run all components building, then you can check what components were failed with the following commands:

cat > check_fails.sh <<EOT
#!/bin/bash
#WDIR=\$1
WDIR=/export/home/du4
subdirs=\$(ls -1 \$WDIR)
for dr in \$subdirs
do
  res=\$(tail -1 \$WDIR/\$dr/berror.log)
  if [[ "\$(echo \$res | grep 'Fetched')" == "" ]]; then
    cat \$WDIR/\$dr/berror.log
  fi
done
echo ""
echo "================= Local repo sources"
cat /etc/apt/sources.list
EOT
chmod 777 ./check_fails.sh
./check_fails.sh

Note : If you need first to build the GCC compiler and use it to build other components, then put the compiler component name to the GCC_COMPILER variable, for example:

GCC_COMPILER="gcc-10". Its exact name you can find in the list_component file.

After the build you an check the components installation by creating the new zone.
