Adapting version after a release of an office ============================================= After a release the entries in cli_ure/version/version.txt must be changed to reflect the versions of the assemblies at the time of the release. Please refer to the document at http://udk.openoffice.org/common/man/spec/assemblyversioning.html for more information about versioning of assemblies.
Step 1: Remove old office installations.
To do this, deinstall all offices, and make sure that there are no assemblies installed in the Global Assembly Cache (GAC). The GAC is contained in C:\Windows\assembly. Change C:\Windows according to your windows installation. Use the Windows Explorer to view the contents of the GAC. Are there any of the following assemblies installed:
cli_uretypes.dll cli_basetypes.dll cli_cppuhelper.dll cli_ure.dll cli_oootypes.dll (build in unoil)
policy.x.y.cli_uretypes.dll policy.x.y.cli_basetypes.dll policy.x.y.cli_ure.dll policy.x.y.cli_cppuhelper.dll policy.x.y.cli_oootypes.dll (build in unoil)
The "x" and "y" in the names of the policy assemblies are to be replaces by version numbers. At the time of writing the real names are:
policy.1.0.cli_uretypes.dll policy.1.0.cli_basetypes.dll policy.1.0.cli_ure.dll policy.1.0.cli_cppuhelper.dll policy.1.0.cli_ootypes.dll (build in unoil)
After deinstalling the offices, there should none of them remain in the GAC. If there are some, then try to remove them by clicking on them an choose uninstall from the context menu of the mouse.
Step 2: Install the office of the last release (respin when using staroffice)
Step 3: Determine the versions of the assemblies
Use the Windows Explorer to view the contents of the Windows\assembly directory. Locate the assemblies and policy assemblies. See step 1 for the names of those assemblies. Take down the version number as can be found in the version column, which is usually right next to the name column.
Step 4: Changing the versions in the cli_ure module.
Open the file cli_ure\version\version.txt. The file contains name/value pairs, such as:CLI_URETYPES_NEW_VERSION=22.214.171.124. The first part of the names represent the assembly which they are referring to. So obviously entries starting with CLI_URETYPES refer to the cli_uretypes.dll. Entries which contain the part "POLICY" refer to the policy assembly. For example: CLI_URETYPES_POLICY_VERSION refers to the policy assembly for cli_uretypes which is named policy.1.0.cli_uretypes.dll
The versions may already have been incremented because someone has changed code after the last release. So if a version from version.txt is greater then the one of the respective assembly in the GAC then leave it at that.
The values have to be adjusted as follows:
XYZ_NEW_VERSION : increase the value of the version GAC. "XYZ_" would be "CLI_URETYPES", "CLI_URE", etc. XYZ_OLD_VERSION : must be changes so that the right version part is one less than XYZ_NEW_VERSION. For example
The affected part is marked by the brackets.
XYZ_POLICY_VERSION: change the version according to the version of the policy assembly from the GAC.
XYZ_POLICY_ASSEMBLY: remain unchanged.
Commit the changes and rebuild the project.
Step 5: Changing the versions in the unoil module
The unoil module builds the cli_oootypes.dll which contains the office types (offapi). Change the contents of unoil/climaker/version.txt similar to the versions.txt in this module. Then rebuild the module
The automatic test in cli_ure/qa/versioning should be extended. See the readme.txt in that directory for more information.
How does the version mechanism works ====================================
The assemblies which are build in this project have a strong name and hence a version. The version should be increased whenever something was fixed or the code has changed in any way. For further information have a look at http://udk.openoffice.org/common/man/spec/assemblyversioning.html
The versions of all assemblies are contained in cli_ure/version/version.txt. This is the place where the versions are changed. This will happen under two circumstances. First, the versions are adjusted AFTER an office was released. The version.txt must then contain the versions at the time of the release. Second, when something was fixed. Then a version should be changed unless this has already be done for the next release. Please look at the document mentioned further above.
If new published UNO types have been added since the last release (product update) then the minor version of cli_uretypes.dll should be incremented. When building the version directory, a script is run that recognizes this and writes a cliureversion.mk file in the bin directory. cliureversion.mk contains all the entries of version.txt. The versions have been incremented by the script. The script obtains the information of new types from unotype_statistics.txt which is build in offapi.
The contents of cliureversion.mk is used when building the assemblies in this project. It is also delivered so that instset_native (or instsetoo_native) can use it when building the installation sets.
The contents of version.txt =========================== The entries in version.txt are needed for building the assemblies and for building the installation set (msi database).
For every assembly exist four entries. For example:
CLI_URETYPES_NEW_VERSION=126.96.36.199 CLI_URETYPES_OLD_VERSION=188.8.131.52-184.108.40.206 CLI_URETYPES_POLICY_VERSION=220.127.116.11 CLI_URETYPES_POLICY_ASSEMBLY=policy.1.0.cli_uretypes
The meaning of these entries is the following:
CLI_URETYPES_NEW_VERSION represents the current version of the assembly.
CLI_URETYPES_OLD_VERSION represents a range of former versions (which were compatible). It has to be placed in the cli_uretypes.config XML file which is part of the policy assembly. This is done automatically. The XYZ_OLD_VERSION and XYZ_NEW_VERSION values are used for the binding redirection of the policy file.
CLI_URETYPES_POLICY_VERSION represents the version of the policy file.
CLI_URETYPES_POLICY_ASSEMBLY represents the name of the policy file.
Please refer to the document at http://udk.openoffice.org/common/man/spec/assemblyversioning.html about how the versions have to look like.
When the minor version is changed, which is the third number from the left, the "old version" and the policy version must be changed as well. Using the former example, an incremented version would look like this: CLI_URETYPES_NEW_VERSION=18.104.22.168 CLI_URETYPES_OLD_VERSION=22.214.171.124-126.96.36.199 CLI_URETYPES_POLICY_VERSION=188.8.131.52 CLI_URETYPES_POLICY_ASSEMBLY=policy.1.0.cli_uretypes
If the major version changed we would have these values: CLI_URETYPES_NEW_VERSION=184.108.40.206 CLI_URETYPES_OLD_VERSION=220.127.116.11-18.104.22.168 CLI_URETYPES_POLICY_VERSION=22.214.171.124 CLI_URETYPES_POLICY_ASSEMBLY=policy.2.0.cli_uretypes
Because a change of a major is only done if the code has changed incompatibly, we must not redirect old client code to the new assembly. Actually we would not need a policy file here. The name of the policy file has changed as well so as to refer to the new version. Since the name is new and refers to the version 2 of cli_uretypes, we can start with the policy version from 1.
The next compatible change would require to change the version to these: CLI_URETYPES_NEW_VERSION=126.96.36.199 CLI_URETYPES_OLD_VERSION=188.8.131.52-184.108.40.206 CLI_URETYPES_POLICY_VERSION=220.127.116.11 CLI_URETYPES_POLICY_ASSEMBLY=policy.2.0.cli_uretypes
Automatic incrementation of the version ======================================= Currently switched off! See cli_ure/version/makefile.mk The automatic incrementation of the version this is done when new published types have been introduce between two releases.In cli_ure/version/makefile.mk the script cli_ure/source/scripts/increment_version.pl is run which creates the cliureversion.mk with the new versions. This automatism only changes the version parts which have the meaning of a compatible change. Which versions are to be incremented is contained in cli_ure/version/incversions.txt. It contains, for example these entries:
CLI_URETYPES_NEW_VERSION CLI_URETYPES_OLD_VERSION CLI_URETYPES_POLICY_VERSION
The names are exactly the same as in version.txt. The script knows how to increase the version of the different types:
Entries ending on _NEW_VERSION: The third number from the left is incremented. Entries ending on _OLD_VERSION: The third number from the left of the second version is incremented. Entries ending on _POLICY_VERSION: The first number from the left is incremented.
For example, the versions in version.txt are: CLI_URETYPES_NEW_VERSION=18.104.22.168 CLI_URETYPES_OLD_VERSION=22.214.171.124-126.96.36.199 CLI_URETYPES_POLICY_VERSION=188.8.131.52
If new types have been added the script would create these entries in cliureversion.mk CLI_URETYPES_NEW_VERSION=184.108.40.206 CLI_URETYPES_OLD_VERSION=220.127.116.11-18.104.22.168 CLI_URETYPES_POLICY_VERSION=22.214.171.124
As one can see from the incversions.txt, the versions of the cli_ure.dll and cli_cppuhelper.dll are also changed. This is because these are dependent on cli_uretypes.dll.
Further notes on increasing the assembly versions ================================ Changing a version for one assembly means changing at least the XYZ_NEW_VERSION, XYZ_OLD_VERSION and XYZ_POLICY_VERSION. In case of an incompatible change, that is one of the first two numbers of the version has been changed, the XYZ_POLICY_ASSEMBLY must also be changed.
When changing a version of an assembly then the versions of the assemblies which depend on it should be changed as well. For example, when changing the version of cli_uretypes.dll, then the versions of cli_ure.dll and cli_cppuhelper.dll should be changed as well. One can use idlasm.exe to see which assemblies are referenced by an assembly. The information is contained in the assemblie's manifest.
If one would not change the versions of the dependent dlls then one would risk that an assembly has the same old version but references a different assembly. For example, say we have a cli_uretypes.dll with version 1 and a cli_ure.dll with version 1. cli_ure.dll references version 1 of cli_uretypes.dll. Now the version of cli_uretypes.dll changes to version 2 and its policy assembly is adapted so that all code that uses version 1 now uses version 2. This would also allow cli_ure.dll o run with the new cli_uretypes.dll. If now cli_ure.dll is build, then it would reference cli_uretypes.dll version 2, because our build environment does not keep the older assembly. The old cli_uretypes.dll version 1 was replaced by version 2. cli_ure.dll now references cli_uretypes.dll version 2 but still has the old version.
rebasing of assemblies ======================================================= Neither assemblies nor policy assemblies may be rebased. This would make the signature invalid. Therefore all assemblies must be contained in postprocess/rebase/no_rebase.txt
