Package Building

If you want to create an OPM package (.opm) you need to create a spec file (.sopm) which includes the properties of the package.

Package Spec File

The OPM package is XML based. You can create/edit the .sopm via a text or XML editor. It contains meta data, a file list and database options.

<Name> *

The package name.

<Name>Calendar</Name>
<Version> *

The package version.

<Version>1.2.3</Version>
<Framework> *

The targeted framework version (7.0.x means e.g. 7.0.1 or 7.0.2).

<Framework>7.0.x</Framework>

Can also be used several times.

<Framework>5.0.x</Framework>
<Framework>6.0.x</Framework>
<Framework>7.0.x</Framework>
<Vendor> *

The package vendor.

<Vendor>OTRS AG</Vendor>
<URL> *

The vendor URL.

<URL>https://otrs.com/</URL>
<License> *

The license of the package.

<License>GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007</License>
<ChangeLog>

The package change log.

<ChangeLog Version="1.1.2" Date="2018-11-15 18:45:21">Added some feature.</ChangeLog>
<ChangeLog Version="1.1.1" Date="2018-11-15 16:17:51">New package.</ChangeLog>
<Description> *

The package description in different languages.

<Description Lang="en">A web calendar.</Description>
<Description Lang="de">Ein Web Kalender.</Description>
Package Actions

The possible actions for the package after installation. If one of these actions is not defined on the package, it will be considered as possible.

<PackageIsVisible>1</PackageIsVisible>
<PackageIsDownloadable>0</PackageIsDownloadable>
<PackageIsRemovable>1</PackageIsRemovable>

A special package action is PackageAllowDirectUpdate. Only if it is defined on the package and set to true, a package can be upgraded from a lower major version (earlier than the last one) to the latest version. (e.g. a package for OTRS 5 updated to OTRS 7).

<PackageAllowDirectUpdate>1</PackageAllowDirectUpdate>

# Some Perl code.
]]></CodeUpgrade>

You also can choose <CodeUpgrade Type="post"> or <CodeUpgrade Type="pre"> to define the time of execution separately (post is default). For more info see Package Life Cycle.

<PackageMerge>

This tag singals that a package has been merged into another package. In this case the original package needs to be removed from the file system and the packages database, but all data must be kept.

Let’s assume that PackageOne was merged into PackageTwo. Then PackageTwo.sopm should contain this:

<PackageMerge Name="MergeOne" TargetVersion="2.0.0"></PackageMerge>

If PackageOne also contained database structures, we need to be sure that it was at the latest available version of the package to have a consistent state in the database after merging the package. The attribute TargetVersion does just this: it signifies the last known version of PackageOne at the time PackageTwo was created. This is mainly to stop the upgrade process if in the user’s system a version of PackageOne was found that is newer than the one specified in TargetVersion as this could lead to problems.

Additionally it is possible to add required database and code upgrade tags for PackageOne to make sure that it gets properly upgraded to the TargetVersion before merging it - to avoid inconsistency problems. Here’s how this could look like:

<PackageMerge Name="MergeOne" TargetVersion="2.0.0">
    <DatabaseUpgrade Type="merge">
        <TableCreate Name="merge_package">
            <Column Name="id" Required="true" PrimaryKey="true" AutoIncrement="true" Type="INTEGER"/>
            <Column Name="description" Required="true" Size="200" Type="VARCHAR"/>
        </TableCreate>
    </DatabaseUpgrade>
</PackageMerge>

As you can see the attribute Type="merge" needs to be set in this case. These sections will only be executed if a package merge is possible.

Package Conditions

IfPackage and IfNotPackage attributes can be added to the regular Database* and Code* sections. If they are present, the section will only be executed if another package is or is not in the local package repository.

<DatabaseInstall IfPackage="AnyPackage">
    # ...
</DatabaseInstall>

or

<CodeUpgrade IfNotPackage="OtherPackage">
    # ...
</CodeUpgrade>

These attributes can be also set in the Database* and Code* sections inside the PackageMerge tags.
