Thanks, this part looks obviously correct. > While at it make sure to release the string_list when done; > push_refs_with_export() already does that. This one takes a bit more digging. I've been bitten before in Git's code by freeing what appeared to be a leak only to find out that we had passed the pointers off to some other data structure which expected them to persist. Here we feed them to set_helper_option(), which passes them to quote_c_style(), which makes a copy into a strbuf. So I think all is well. -Peff
