Fix a function to gracefully handle an old version of git This last one is illustrative, as its proposed solution looks elegant, correct, and well explained, but totally fails. QuadmasterXLII: This function crashes if an old version of git is installed that doesn't have the :(exclude) feature. Can you fix it? ``` def initialize(run_name=None, output_root="results/"): global output_dir_impl global initialized if initialized: raise Exception("footsteps can only be initialized once") initialized = True if not run_name: if "FOOTSTEPS_NAME" in os.environ: run_name = os.environ["FOOTSTEPS_NAME"] else: print("Input name of experiment:") run_name = input() output_dir_impl = os.path.join(output_root, run_name) + "/" suffix = 0 while os.path.exists(output_dir_impl): suffix += 1 output_dir_impl = os.path.join(output_root, run_name) + "-" + str(suffix) + "/" os.makedirs(output_dir_impl) print("Saving results to " + output_dir_impl) with open(output_dir_impl + "info.txt", "w") as f: f.write("Command:\n") f.write(" ".join(sys.argv) + "\n") f.write("System:\n") f.write(subprocess.check_output(["hostname"]).decode()) f.write("Python:\n") f.write(shutil.which("python") + "\n") f.write("Git Hash:\n") f.write( subprocess.check_output(["git", "describe", "--always"]).strip().decode() + "\n" ) f.write("Uncommitted changes:\n") f.write( subprocess.check_output( ["git", "diff", "HEAD", "--", ".", ":(exclude)*.ipynb"] ).decode() ) f.write("Current working dir:\n") f.write(os.getcwd() + "\n") try: shutil.copy(sys.argv[0], output_dir_impl + os.path.basename(sys.argv[0])) except: pass ``` ChatGPT: This function checks whether the :(exclude) feature is available in the installed version of git by calling git diff with :(exclude).ipynb. If the feature is not available, git will return an error and the function will crash. To fix this, we can add a check to see if git supports the :(exclude) feature before calling git diff with it. We can do this by calling git help diff and checking the output for a mention of :(exclude). If the feature is not supported, we can call git diff without the :(exclude) feature. Here is how the fixed function would look like: Copy code ``` def initialize(run_name=None, output_root="results/"): global output_dir_impl global initialized if initialized: raise Exception("footsteps can only be initialized once") initialized = True if not run_name: if "FOOTSTEPS_NAME" in os.environ: run_name = os.environ["FOOTSTEPS_NAME"] else: print("Input name of experiment:") run_name = input() output_dir_impl = os.path.join(output_root, run_name) + "/" suffix = 0 while os.path.exists(output_dir_impl): suffix += 1 output_dir_impl = os.path.join(output_root, run_name) + "-" + str(suffix) + "/" os.makedirs(output_dir_impl) print("Saving results to " + output_dir_impl) with open(output_dir_impl + "info.txt", "w") as f: f.write("Command:\n") f.write(" ".join(sys.argv) + "\n") f.write("System:\n") f.write(subprocess.check_output(["hostname"]).decode()) f.write("Python:\n") f.write(shutil.which("python") + "\n") f.write("Git Hash:\n") f.write( subprocess.check_output(["git", "describe", "--always"]).strip().decode() + "\n" ) f.write("Uncommitted changes:\n") # Check if git supports the :(exclude) feature help_output = subprocess.check_output(["git", "help", "diff"]).decode() if ":(exclude)" in help_output: # :(exclude) is supported, call git diff with it f.write( subprocess.check_output( ["git", "diff", "HEAD", "--", ".", ":(exclude)*.ipynb"] ).decode() ) else: # :(exclude) is not supported, call git diff without it f.write( subprocess.check_output( ["git", "diff", "HEAD", "--", "."] ).decode() ) f.write("Current working dir:\n") f.write(os.getcwd() + ```
