Merge branch 'ds/close-object-store' into maint

2019-07-29T19:38:22Z

The commit-graph file is now part of the "files that the runtime may keep open file descriptors on, all of which would need to be closed when done with the object store", and the file descriptor to an existing commit-graph file now is closed before "gc" finalizes a new instance to replace it. * ds/close-object-store: packfile: rename close_all_packs to close_object_store packfile: close commit-graph in close_all_packs commit-graph: use raw_object_store when closing commit-graph: extract write_commit_graph_file() commit-graph: extract copy_oids_to_commits() commit-graph: extract count_distinct_commits() commit-graph: extract fill_oids_from_all_packs() commit-graph: extract fill_oids_from_commit_hex() commit-graph: extract fill_oids_from_packs() commit-graph: create write_commit_graph_context commit-graph: remove Future Work section commit-graph: collapse parameters into flags commit-graph: return with errors during write commit-graph: fix the_repository reference

packfile: rename close_all_packs to close_object_store

2019-06-12T18:33:54Z

The close_all_packs() method is now responsible for more than just pack-files. It also closes the commit-graph and the multi-pack-index. Rename the function to be more descriptive of its larger role. The name also fits because the input parameter is a raw_object_store. Signed-off-by: Derrick Stolee Signed-off-by: Junio C Hamano

packfile: fix pack basename computation

2019-04-16T07:58:21Z

When we have a multi-pack-index that covers many packfiles, we try to avoid opening the .idx for those packfiles. To do that we feed the pack name to midx_contains_pack(). But that function wants to see only the basename, which we compute using strrchr() to find the final slash. But that leaves an extra "/" at the start of our string. We can fix this by incrementing the pointer. That also raises the question of what to do when the name does not have a '/' at all. This should generally not happen (we always find files in "pack/"), but it doesn't hurt to be defensive here. Let's wrap all of that up in a helper function and make it publicly available, since a later patch will need to use it, too. The tests don't notice because there's nothing about opening those .idx files that would cause us to give incorrect output. It's just a little slower. The new test checks this case by corrupting the covered .idx, and then making sure we don't complain about it. We also have to tweak t5570, which intentionally corrupts a .idx file and expects us to notice it. When run with GIT_TEST_MULTI_PACK_INDEX, this will fail since we now will (correctly) not bother opening the .idx at all. We can fix that by unconditionally dropping any midx that's there, which ensures we'll have to read the .idx. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

packfile.h: drop extern from function declarations

2019-04-16T07:58:21Z

As CodingGuidelines recommends, we do not need an "extern" when declaring a public function. Let's drop these. Note that we leave the extern on report_garbage(), as that is actually a function pointer, not a function itself. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

midx: during verify group objects by packfile to speed verification

2019-03-22T05:31:11Z

Teach `multi-pack-index verify` to sort the set of object by packfile so that only one packfile needs to be open at a time. This is a performance improvement. Previously, objects were verified in OID order. This essentially requires all packfiles to be open at the same time. If the number of packfiles exceeds the open file limit, packfiles would be LRU-closed and re-opened many times. Signed-off-by: Jeff Hostetler Signed-off-by: Junio C Hamano
