From 263db403face43927c2eb545a2e6ebb39aae4239 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 12 Nov 2018 09:48:47 -0500 Subject: rename "alternate_object_database" to "object_directory" In preparation for unifying the handling of alt odb's and the normal repo object directory, let's use a more neutral name. This patch is purely mechanical, swapping the type name, and converting any variables named "alt" to "odb". There should be no functional change, but it will reduce the noise in subsequent diffs.

The callers generally keep their own static buffer to avoid excessive reallocations. But for alternate directories, each struct carries its own scratch buffer. This is needlessly different; let's unify them. We could go either direction here, but this patch moves the alternates struct over to the main directory style (rather than vice-versa). Technically the alternates style is more efficient, as it avoids rewriting the object directory name on each call. But this is unlikely to matter in practice, as we avoid reallocations either way (and nobody has ever noticed or complained that the main object directory is copying a few extra bytes before making a much more expensive system call). And this has the advantage that the reusable buffers are tied to particular calls, which makes the invalidation rules simpler (for example, the return value from stat_sha1_file() used to be invalidated by basically any other object call, but now it is affected only by other calls to stat_sha1_file()). We do steal the trick from alt_sha1_path() of returning a pointer to the filled buffer, which makes a few conversions more convenient.

As a result, many places in the code basically look like this: do_something(r->objects->objdir); for (odb = r->objects->alt_odb_list; odb; odb = odb->next) do_something(odb->path); That gets annoying when do_something() is non-trivial, and we've resorted to gross hacks like creating fake alternates (see find_short_object_filename()). Instead, let's give each raw_object_store a unified list of object_directory structs. The first will be the main store, and everything after is an alternate. Very few callers even care about the distinction, and can just loop over the whole list (and those who care can just treat the first element differently). A few observations: - we don't need r->objects->objectdir anymore, and can just mechanically convert that to r->objects->odb->path - object_directory's path field needs to become a real pointer rather than a FLEX_ARRAY, in order to fill it with expand_base_dir() - we'll call prepare_alt_odb() earlier in many functions (i.e., outside of the loop). This may result in us calling it even when our function would be satisfied looking only at the main odb. But this doesn't matter in practice. It's not a very expensive operation in the first place, and in the majority of cases it will be a noop. We call it already (and cache its results) in prepare_packed_git(), and we'll generally check packs before loose objects. So essentially every program is going to call it immediately once per program. Arguably we should just prepare_alt_odb() immediately upon setting up the repository's object directory, which would save us sprinkling calls throughout the code base (and forgetting to do so has been a source of subtle bugs in the past). But I've stopped short of that here, since there are already a lot of other moving parts in this patch. - Most call sites just get shorter. The check_and_freshen() functions are an exception, because they have entry points to handle local and nonlocal directories separately.
