2021-10-27llvm_tools: Add lldb_server to updated_packagesRyan Beltran
This CL adds dev-util/lldb-server to the list of packages updated by various tools. Additionally, it updates the default packages in update_chromeos_llvm_hash.py so that we don't have to manually supply them anymore, and refactors other scripts to use that list instead of maintaining their own.

2020-11-21llvm_tools: pass cl number as str to avoid type errorBob Haarman
llvm_bisection.py invokes the Gerrit CLI to abandon CLs created as part of the bisection. It passes a CL number to the command. Before this change, the CL number was passed as an int, which leads to the following error: Traceback (most recent call last): File "./auto_llvm_bisection.py", line 103, in main bisection_ret = llvm_bisection.main(args_output) File "/usr/local/google/home/inglorion/chromiumos/src/third_party/toolchain-utils/llvm_tools/llvm_bisection.py", line 364, in main subprocess.check_output([gerrit, 'abandon', build['cl']], File "/usr/lib/python3.8/subprocess.py", line 411, in check_output return run(*popenargs, stdout=PIPE, timeout=timeout, check=True, File "/usr/lib/python3.8/subprocess.py", line 489, in run with Popen(*popenargs, **kwargs) as process: File "/usr/lib/python3.8/subprocess.py", line 854, in __init__ self._execute_child(args, executable, preexec_fn, close_fds, File "/usr/lib/python3.8/subprocess.py", line 1637, in _execute_child self.pid = _posixsubprocess.fork_exec( TypeError: expected str, bytes or os.PathLike object, not int With this change, we convert the value to an str first, avoiding the type error.

Currently, the scripts are in python2, so migrating them to python3 so they are more maintainable. BUG=None TEST=Ran each script by itself with various input (e.g. different google3, tot, etc.).

2019-09-03LLVM tools: Added auto bisection of LLVMSalud Lemus
Similar to 'llvm_bisection.py' script but uses `cros buildresult` to update each tryjob's 'status' field. The script sleeps for X minutes and continues where bisection left off (similar behavior if script terminates). The script is an infinite loop but terminates when there are no more revisions between the new 'start' and new 'end' or if an exception happens. This script is using the scripts such as bisection script and updating a tryjob's status script in a loop. BUG=None TEST=Ran 'auto_llvm_bisection.py' script with a file that was not created and start revision of 369410 and end revision of 369420. Successfully created tryjobs between the start and end and the script went to sleep for X minutes and woke up to resume where bisection left off.

2019-08-28LLVM tools: Added support for 'skip' and executing a custom scriptSalud Lemus
If a tryjob's status is set to 'skip', then that tryjob will not be considered when bisecting LLVM. And for executing a custom script, the exit code will be used by a mapping that sets the 'status' to the equivalent value of the exit code. BUG=None TEST=Ran the 'update_tryjob_status.py' with the 'skip' option and successfully set the tryjob's status to 'skip'. Also, created a testing script to serve as the custom script. Successfully set the 'status' value based off of the custom script's exit code.
