want to get source_code of modified_files

[YuLiu]

Describe the bug
For a commit which modified single file,I want to get the source_code and source_code_before from the modified_files[0],but I meet with a RecursionError:maximum recursion depth exceeded while calling a Python object

To Reproduce

for commit in Repository('https://github.com/AUTOMATIC1111/stable-diffusion-webui').traverse_commits():
    #print('Hash {}, message {}'.format(commit.hash, commit.msg))
    if not commit_filter(commit):
        continue
    num += 1
    print('Hash {} Code {}'.format(commit.hash, commit.modified_files[0].source_code))
    #print('Hash {}'.format(commit.hash))
    source = ""
    if commit.modified_files[0].source_code is not None:
        source = commit.modified_files[0].source_code
    else:
        source = "None"
    # for mod in commit.modified_files:
    #     print('File {} has been {}ed'.format(mod.filename, mod.change_type))
    chosen_commit.append({
            'hash': commit.hash,
            'msg': commit.msg,
            'source_code': source
            #'source_code_before': source_code_before,
            #'changed_methods': changed_methods
        })

running above code,I can see hash and code printed in the console.But after some time,it give RecursionError.I am confused that if I doesn't mention modified_files[0].source_code,for example,only record hash and msg into chosen_commit,it can finished successfully.I am appreciated if anyone can give me some advice,Thanks

Hi! I tried it on my laptop but couldn't repro:

from pydriller import Repository

chosen_commit = []
num_commits = 0
for commit in Repository('https://github.com/AUTOMATIC1111/stable-diffusion-webui').traverse_commits():
    try:
        num_commits += 1
        print('{} Hash {}'.format(num_commits, commit.hash))
        source = ""
        if len(commit.modified_files) == 0:
            continue

        if commit.modified_files[0].source_code is not None:
            source = commit.modified_files[0].source_code
        else:
            source = "None"
        chosen_commit.append({
                'hash': commit.hash,
                'msg': commit.msg,
                'source_code': source
            })
    except ValueError as e:
        print(e)

This will run until the end:

...

7368 Hash a183ea4ba773da5144e9f6b99fa48bff13078d2a

Also, in your code there are some issues (for example, you always analize only 1 file per commit, and not all commits have files).
