Welcome to MyFirstUDRKit. As you can tell from the name, this plugin is not intended for production use. It is just to play with. When you are ready feel free to fork it and give it a new name.
What is in the kit?
There are currently four functions available. Two
flagged are simple smoke test functions. They do very little but they demonstrate two things:
- how to write basic C code in a UDR
- do quick tests to verify the basics of UDR plugin develeopment and testing.
There are two other functions available:
These are more ambitious.
- they are written in C++
- they demonstrate how to work with the new Firebird OO API
Forking the repository
For test purposes you can just clone the repo and try building and testing the code. However, for serious work it is recommended that you clone the repo and give the project a new name. When doing so be sure to search and replace all references to MyFirstUDRKit to your new project name. There are two strings to replace:
Setting up cmake
Run the cmake gui and fill in the path information. Set the source to the root of the location where you have cloned the repo. CMake looks for the file
CMakeLists.txt. Binaries will be built under
build/x86_64-linux for linux.
Click on Configure to generate the default config for the current platform. This will open a dialogue. When prompted choose the
Unix makefiles generator for linux. Under Windows choose
Visual Studio 15 2017 and be sure to set the
Optional platform for generator to x64 for windows as in the screenshot below:
Finish and you should then see a screen similar to this:
Under linux the only change needed at this stage is to set
CMAKE_BUILD_TYPE to Debug`. Under Windows there should be nothing further to do.
You can then click on
Generate and you should end up with a screen similar to this:
If you want to start again be sure to click on
Building the kit
On linux just do:
cd build/x86_64-linux make
On windows just open the solution in visual studio and build the solution.
There is a test suite available for testing under linux in the
- compile fb for valgrind
- stress test for leakage
Run the sql on the target database
In the sql directory there are two scripts.
MyFirstUDRKit.ddl contains the function declarations. You can run the script directly on your database to register the functions.
MyFirstUDRKitPackage.sql, although incomplete, demonstrates how you can declare the functions as part of a package.
When things go wrong
Errors when registering a function
Invalid index 1 in function IMetadataBuilder::setType
This error indicates that the parameters in the sql function declaration do not match the parameters in the actual function. Check your sql with the FB_UDR_MESSAGE declarations.
