2021-06-28add_ref_decoration(): rename s/type/deco_type/Libravatar Jeff King1-7/+7
Now that we have two types (a decoration type and an object type) in the function, let's give them both unique names to avoid accidentally using one instead of the other. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-06-28load_ref_decorations(): avoid parsing non-tag objectsLibravatar Jeff King1-2/+4
When we load the ref decorations, we parse the object pointed to by each ref in order to get a "struct object". This is unnecessarily expensive; we really only need the object struct, and don't even look at the parsed contents. The exception is tags, which we do need to peel. We can improve this by looking up the object type first (which is much cheaper), and skipping the parse entirely for non-tags. This increases the work slightly for annotated tags (which now do a type lookup _and_ a parse), but decreases it a lot for other types. On balance, this seems to be a good tradeoff. In my git.git clone, with ~2k refs, most of which are branches, the time to run "git log -1 --decorate" drops from 34ms to 11ms. Even on my linux.git clone, which contains mostly tags and only a handful of branches, the time drops from 30ms to 19ms. And on a more extreme real-world case with ~220k refs, mostly non-tags, the time drops from 2.6s to 650ms. That command is a lop-sided example, of course, because it does as little non-loading work as possible. But it does show the absolute time improvement. Even in something like a full "git log --decorate" on that extreme repo, we'd still be saving 2s of CPU time. Ideally we could push this even further, and avoid parsing even tags, by relying on the packed-refs "peel" optimization (which we could do by calling peel_iterated_oid() instead of peeling manually). But we can't do that here. The packed-refs file only stores the bottom-layer of the peel (so in a "tag->tag->commit" chain, it stores only the commit as the peel result). But the decoration code wants to peel the layers individually, annotating the middle layers of the chain. If the packed-refs file ever learns to store all of the peeled layers, then we could switch to it. Or even if it stored a flag to indicate the peel was not multi-layer (because most of them aren't), then we could use it most of the time and fall back to a manual peel for the rare cases.

2021-06-28object.h: add lookup_object_by_type() functionLibravatar Jeff King3-18/+25
In some cases it's useful for efficiency reasons to get the type of an object before deciding whether to parse it, but we still want an object struct. E.g., in reachable.c, bitmaps give us the type, but we just want to mark flags on each object. Likewise, we may loop over every object and only parse tags in order to peel them; checking the type first lets us avoid parsing the non-tags. But our lookup_blob(), etc, functions make getting an object struct annoying: we have to call the right function for every type. And we cannot just use the generic lookup_object(), because it only returns an already-seen object; it won't allocate a new object struct. Let's provide a function that dispatches to the correct lookup_* function based on a run-time type. In fact, reachable.c already has such a helper, so we'll just make that public. I did change the return type from "void *" to "struct object *". While the former is a clever way to avoid casting inside the function, it's less safe and less informative to people reading the function declaration. The next commit will add a new caller.

2021-06-28log: avoid loading decorations for userformats that don't need itLibravatar Jeff King3-0/+8
If no --decorate option is given, we default to auto-decoration. And when that kicks in, cmd_log_init_finish() will unconditionally load the decoration refs. However, if we are using a user-format that does not include "%d" or "%D", we won't show the decorations at all, so we don't need to load them. We can detect this case and auto-disable them by adding a new field to our userformat_want helper. We can do this even when the user explicitly asked for --decorate, because it can't affect the output at all. This patch consistently reduces the time to run "git log -1 --format=%H" on my git.git clone (with ~2k refs) from 34ms to 7ms. On a much more extreme real-world repository (with ~220k refs), it goes from 2.5s to 4ms. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-06-28pretty.h: update and expand docstring for userformat_find_requirements()Libravatar Jeff King1-2/+5
The comment only mentions "notes", but there are more fields now (and I'm about to add another). Let's make it more general, and stick the struct next to the function to make the list of possibilities obvious. While we're touching this comment, let's also mention the behavior of NULL, which some callers rely on (though in the long run, this global is pretty nasty and probably should get moved into rev_info).

2021-06-06parallel-checkout: avoid dash local bug in testsLibravatar René Scharfe1-1/+1
Dash bug https://bugs.launchpad.net/ubuntu/+source/dash/+bug/139097 lets the shell erroneously perform field splitting on the expansion of a command substitution during declaration of a local variable. It causes the parallel-checkout tests to fail e.g. when running them with /bin/dash on MacOS 11.4, where they error out like this: ./t2080-parallel-checkout-basics.sh: 33: local: 0: bad variable name That's because the output of wc -l contains leading spaces and the returned number of lines is treated as another variable to declare, i.e. as in "local workers= 0". Work around it by enclosing the command substitution in quotes.

Some platforms, like NonStop do not automatically restart fsync() when interrupted by a signal, even when that signal is setup with SA_RESTART. This can lead to test breakage, e.g., where "--progress" is used, thus SIGALRM is sent often, and can interrupt an fsync() syscall. Make sure we deal with such a case by retrying the syscall ourselves. Luckily, we call fsync() fron a single wrapper, fsync_or_die(), so the fix is fairly isolated. Reported-by: Randall S.
