I’d like to share my work with you: https://news.ycombinator.com/item?id=47137452 It shows that I posted just a little later than you. I agree that the chances of something going wrong with timestamps are low, but I still think it’s worth considering as a potential security risk or injection vector — although I’m not sure how realistic that threat actually is. Regarding UUIDs, you can get the best of both worlds: sequential IDs are convenient, and adding a small number of random characters can help avoid name collisions. Since the random component only needs to ensure uniqueness across local repositories, it doesn’t require many characters. I can see that you’ve put a great deal of effort into this, especially with the various bridging components. I built a simple bridge myself and ran some tests using the pandas project (https://github.c

om/pandas-dev/pandas ), which has more than 30,000 issues. Even storing only metadata (such as title and type, excluding the body) as plain text takes more than 100 MB, which seems quite large. In comparison, storing the same data in SQL takes only about 10 MB, and packed Git objects are comparable. So while storing issues as Git commits certainly has some benefits, I don't see much advantage beyond that. It also seems that most users would not be able to make practical use of this approach easily — for example, for batch processing — unless they are already quite comfortable working directly with Git commits. I'm curious about what considerations led you to decide to store issues as empty Git commits. I would appreciate it if you could share your reasoning with me.

Unrelated, but I personally am not satisfied with the performance of Panda's XLSX export. As you can see here [0], the code does really strange things. It takes cell.style and throws it into json.dumps() to generate a key for a dictionary so that they can cache the XlsxStyler.convert(cell.style) result. Except, the vast majority of cells do not have any styling whatsoever, so json.dumps is producing the string "null", which is then used to lookup None. The low hanging fruit are jaw dropping. You can easily speed up the code 10%+ by adding a simple check "if cell.style is not None or fmt is not None:" and switching from json.dumps(cell.style) to str(cell.style). If I wanted an easy weekend project that positively impacts many people this is what I'd work on. [0] https://github.com/pandas-dev/pandas/blob/main/pandas/io/exc...
