From 89219bc0cd09ada8a204e0ace0bd15decaea7d31 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Thu, 30 Oct 2025 11:38:40 +0100 Subject: http: refactor subsystem to use `packfile_list`s The dumb HTTP protocol directly fetches packfiles from the remote server and temporarily stores them in a list of packfiles. Those packfiles are not yet added to the repository's packfile store until we finalize the whole fetch. Refactor the code to instead use a `struct packfile_list` to store those packs. This prepares us for a subsequent change where the `->next` pointer of `struct packed_git` will go away. Note that this refactoring creates some temporary duplication of code, as we now have both `packfile_list_find_oid()` and `find_oid_pack()`. The latter function will be removed in a subsequent commit though.
