alloc: allow arbitrary repositories for alloc functions We have to convert all of the alloc functions at once, because alloc_report uses a funky macro for reporting. It is better for the sake of mechanical conversion to convert multiple functions at once rather than changing the structure of the reporting function. We record all memory allocation in alloc.c, and free them in clear_alloc_state, which is called for all repositories except the_repository.

Add missing includes and forward declarations I looped over the toplevel header files, creating a temporary two-line C program for each consisting of #include "git-compat-util.h" #include $HEADER This patch is the result of manually fixing errors in compiling those tiny programs.

object_as_type: initialize commit-graph-related fields of 'struct commit' When the commit graph and generation numbers were introduced in commits 177722b344 (commit: integrate commit graph with commit parsing, 2018-04-10) and 83073cc994 (commit: add generation number to struct commit, 2018-04-25), they tried to make sure that the corresponding 'graph_pos' and 'generation' fields of 'struct commit' are initialized conservatively, as if the commit were not included in the commit-graph file. Alas, initializing those fields only in alloc_commit_node() missed the case when an object that happens to be a commit is first looked up via lookup_unknown_object(), and is then later converted to a 'struct commit' via the object_as_type() helper function (either calling it directly, or as part of a subsequent lookup_commit() call). Consequently, both of those fields incorrectly remain set to zero, which means e.g. that the commit is present in and is the first entry of the commit-graph file. This will result in wrong timestamp, parent and root tree hashes, if such a 'struct commit' instance is later filled from the commit-graph. Extract the initialization of 'struct commit's fields from alloc_commit_node() into a helper function, and call it from object_as_type() as well, to make sure that it properly initializes the two commit-graph-related fields, too. With this helper function it is hopefully less likely that any new fields added to 'struct commit' in the future would remain uninitialized. With this change alloc_commit_index() won't have any remaining callers outside of 'alloc.c', so mark it as static.

alloc: make allocate_alloc_state and clear_alloc_state more consistent Since both functions are using the same data type, they should either both refer to it as void *, or both use the real type (struct alloc_state *). Opt for the latter. Reviewed-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
