From cfc62fc98c0510e9ea0eeedd473411415fd33fac Mon Sep 17 00:00:00 2001 From: Stefan Beller Date: Fri, 23 Mar 2018 18:21:04 +0100 Subject: [PATCH] sha1_file: add repository argument to link_alt_odb_entry MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add a repository argument to allow the link_alt_odb_entry caller to be more specific about which repository to act on. This is a small mechanical change; it doesn't change the implementation to handle repositories other than the_repository yet. Since the implementation does not yet work with other repositories, use a wrapper macro to enforce that the caller passes in the_repository as the first argument. It would be more appealing to use BUILD_ASSERT_OR_ZERO to enforce this, but that doesn't work because it requires a compile-time constant and common compilers like gcc 4.8.4 do not consider "r == the_repository" a compile-time constant. This and the following three patches add repository arguments to link_alt_odb_entry, read_info_alternates, link_alt_odb_entries and prepare_alt_odb. Three out of the four functions are found in a recursive call chain, calling each other, and one of them accesses the repositories `objectdir` (which was migrated; it was an obvious choice) and `ignore_env` (which we need to keep in the repository struct for clarify); hence we will pass through the repository unlike just the object store object + the ignore_env flag.
