Hi Junio, Sorry for a delayed response. I have been working on something that I hope to send to the list shortly to discuss. In the meantime...

Thanks for the suggestion. Your approach is much more favorable than what I had written here, since it does allow me to unconditionally call 'string_list_clear(...)' instead of 'UNLEAK', which all three of us dislike :). Below is an amended patch; please use this as 4/8 instead of the original when queuing. I'd send you a re-rolled series, but the rest of the patches apply cleanly on top, so I don't think there is a need unless it would make things more convenient for you. -- >8 -- Subject: [PATCH] builtin/commit-graph.c: extract 'read_one_commit()' With either '--stdin-commits' or '--stdin-packs', the commit-graph builtin will read line-delimited input, and interpret it either as a series of commit OIDs, or pack names. In a subsequent commit, we will begin handling '--stdin-commits' differently by processing each line as it comes in, instead of in one shot at the end. To make adequate room for this additional logic, split the '--stdin-commits' case from '--stdin-packs' by only storing the input when '--stdin-packs' is given. In the case of '--stdin-commits', feed each line to a new 'read_one_commit' helper, which (for now) will merely call 'parse_oid_hex'.
