Preupgrade Assistant contents Packaging guidelines

How to package a Preupgrade Assistant contents

Contents files are packaged as a subpackage of main package (e.g mariadb)

Naming guidelines

Every Preupgrade Assistant content subpackage name must start with preupgrade-assistant-contents- followed by original package name.

For example Preupgrade Assistant content subpackage for mariadb will be named preupgrade-assistant-contents-mariadb.

Dependencies

• All packages must have

 Requires: preupgrade-assistant
 BuildRequires: preupgrade-assistant-devel

Devel package contains macros and contents validating check script.

Architecture

• All preupgrade-assistant-contents-* subpackages must be architecture independent, i.e. have BuildArch: noarch.

Macros

• Macro denoting the parent directory where the package files go is %{preupgrade_dir}. This currently expands to /usr/share/preupgrade.
• Macro %{preupg_number} means source release from which the system is going to be upgraded, e.g. Fedora 22.
• Macro %{postupg_number} means target release to which the system is going to be upgraded, e.g. Fedora 23.
• Macro %{preupg_results} means where the contents files are generated

Prep section

Copy all contents files to Fedora%{preupg_number}_%{postupg_number}/%{name} directory.

Content files are:

• INI file
• check_script (python or bash)
• text file with solution description.

Build section

Run command:

%{preupgrade_build} Fedora%{preupg_number}_%{postupg_number}/%{name}/

%{preupgrade_build} command has to success. Warning can be suppressed.

Install section

All files from preupgrade directory should be installed with

%install
...
mkdir -p ${buildroot}%{preupgrade_dir}/Fedora%{preupg_number}_%{postupg_number}/%{name}
install -p -m 755 %{SourceY} ${buildroot}%{preupgrade_dir}/Fedora%{preupg_number}_%{postupg_number}/%{name}/check.sh
install -p -m 644 %{SourceZ} ${buildroot}%{preupgrade_dir}/Fedora%{preupg_number}_%{postupg_number}/%{name}/solution.txt
install -p -m 644 Fedora%{preupg_number}_%{postupg_number}-%{preupg_results}/%{name}/group.xml ${buildroot}%{preupgrade_dir}/Fedora%{preupg_number}_%{postupg_number}/%{name}/group.xml

Files section

• Directory where Preupgrade Assistant installs files and directories must be owned by the subpackage

%files
...
%files -n preupgrade-assistant-contents-%{name}
%dir %{preupgrade_dir}/Fedora%{preupg_number}_%{postupg_number}/%{name}

• All files except text files should be listed like

%files
...
%files -n preupgrade-assistant-contents-%{name}
%{preupgrade_dir}/Fedora%{preupg_number}_%{postupg_number}/%{name}/*.{sh,py}
%{preupgrade_dir}/Fedora%{preupg_number}_%{postupg_number}/%{name}/*.xml

• All text files from content should be listed via

%files
...
%files -n preupgrade-assistant-contents-%{name}
%doc %{preupgrade_dir}/Fedora%{preupg_number}_%{postupg_number}/%{name}/*.txt

Directory ownership

Directories %{preupgrade_dir} and %{preupgrade_dir}/Fedora%{preupg_number}_%{postupg_number} are owned by package preupgrade-assistant itself.
