[Lldb-commits] New llvm build server account request

Tue Oct 20 15:29:05 PDT 2015

Hello Kamil, Galina,

If you would like to build LLDB with cmake and ninja, I suggest to consider
the following two factory functions.
Depends on what you described, I feel the first one works better for you.

1. getLLDBUbuntuCMakeBuildFactory
If you only run local lldb tests, this is the factory to use.

For example, if you would like to build host lldb with clang and Release
config, and run tests with clang on x86_64 host,
then call the function this way,

getLLDBUbuntuCMakeBuildFactory(build_compiler = "clang",
                                   build_type = "Release",
                                   local_test_archs=["x86_64"],
                                   local_test_compilers=["clang"])
If you would like to run local tests with gcc compiler as well, then pass
local_test_compilers=["clang", "gcc"]

Dependency: You need to have the required packages to build lldb.

Note*: please disable the last step in this function
"archiveLLDBTestTraces", this steps will upload the log files to a cloud
storage that you might not have access to.

2. getLLDBScriptCommandsFactory

If you have multiple targets to run tests against, for example, remote
linux, remote android targets and etc, you should choose this factory.
The advantage of this factory is that it calls a script in each step, so
it's highly configurable and easy to make changes.
You just need to make sure the scripts are in builder machine and have the
correct commands.
For your reference, the ones that we're currently using could be found here.
https://android.googlesource.com/platform/external/lldb-utils/+/lldb-master-dev/buildbotScripts/bashShell/svntotbuild/
updateScript as the first step, is just copy the scripts to local builders.

Please let me know if you have further questions.

Thanks,
Ying
