4 years agotree-diff: avoid alloca for large allocations
Jeff King [Tue, 7 Jun 2016 22:53:00 +0000 (18:53 -0400)]
tree-diff: avoid alloca for large allocations

Commit 72441af (tree-diff: rework diff_tree() to generate
diffs for multiparent cases as well, 2014-04-07) introduced
the use of alloca so that the common cases of commits with 1
or 2 parents would not be adversely affected by going
through the multi-parent code.

However, our xalloca is not ideal when the number of parents
grows very large:

  1. If the requested size is too large for our stack,
     alloca() has no way to tell us, and we simply segfault
     while trying to access the memory.

  2. It does not use our usual memory_limit_check() logic.

I measured, and alloca is indeed buying us a very small
speedup over xmalloc()/free(). So we'd want to keep
something like it.

This patch simply puts a conditional in place at each
callsite: we use alloca for common known-small numbers of
parents, and otherwise use the heap. We are technically
still vulnerable to (1), but no more so than if we simply
put a few dozen bytes on the stack, which we must do all the
time anyway. And likewise, we technically miss a memory
limit check if it is tiny, but such a limit is pointless.

An alternative to this would be implement something like:

  struct tree *tp, tp_fallback[2];
  if (nparent <= ARRAY_SIZE(tp_fallback))
          tp = tp_fallback;
  else
  ALLOC_ARRAY(tp, nparent);
  ...
  if (tp != tp_fallback)
  free(tp);

That would let us drop our xalloca() portability code
entirely. But in my measurements, this seemed to perform
slightly worse than the xalloca solution.

Note in the example above, and in the patch below, I've used
ALLOC_ARRAY() to replace the manual xmalloc(nr * sizeof(*x)).
Besides being shorter, this has the bonus that one cannot
accidentally overflow a size_t during that computation.

4 years agoregex: fix a SIZE_MAX macro redefinition warning
Ramsay Jones [Tue, 7 Jun 2016 00:35:33 +0000 (01:35 +0100)]
regex: fix a SIZE_MAX macro redefinition warning

Since commit 56a1a3ab ("Silence GCC's \"cast of pointer to integer of a
different size\" warning", 26-10-2015), sparse has been issuing a macro
redefinition warning for the SIZE_MAX macro. However, gcc did not issue
any such warning.

After commit 56a1a3ab, in terms of the order of #includes and #defines,
the code looked something like:

  $ cat -n junk.c
       1 #include <stddef.h>
       2
       3 #define SIZE_MAX ((size_t) -1)
       4
       5 #include <stdint.h>
       6
       7 int main(int argc, char *argv[])
       8 {
       9 return 0;
      10 }
  $
  $ gcc junk.c
  $

However, if you compile that file with -Wsystem-headers, then it will
also issue a warning. Having set -Wsystem-headers in CFLAGS, using the
config.mak file, then (on cygwin):

  $ make compat/regex/regex.o
      CC compat/regex/regex.o
  In file included from /usr/lib/gcc/x86_64-pc-cygwin/4.9.3/include/stdint.h:9:0,
                   from compat/regex/regcomp.c:21,
                   from compat/regex/regex.c:77:
  /usr/include/stdint.h:362:0: warning: "SIZE_MAX" redefined
   #define SIZE_MAX (__SIZE_MAX__)
   ^
  In file included from compat/regex/regex.c:69:0:
  compat/regex/regex_internal.h:108:0: note: this is the location of the previous definition
   # define SIZE_MAX ((size_t) -1)
   ^
  $

The compilation of the compat/regex code is somewhat unusual in that the
regex.c file directly #includes the other c files (regcomp.c, regexec.c
and regex_internal.c). Commit 56a1a3ab added an #include of <stdint.h>
to the regcomp.c file, which results in the redefinition, since this is
included after the regex_internal.h header. This header file contains a
'fallback' definition for SIZE_MAX, in order to support systems which do
not have the <stdint.h> header (the HAVE_STDINT_H macro is not defined).

In order to suppress the warning, we move the #include of <stdint.h>
from regcomp.c to the start of the compilation unit, close to the top
of regex.c, prior to the #include of the regex_internal.h header.

reflog: continue walking the reflog past root commits

If a repository contains more than one root commit, then its HEAD
reflog may contain multiple "creation events", i.e. entries whose
"from" value is the null sha1.  Listing such a reflog currently stops
prematurely at the first such entry, even when the reflog still
contains older entries.  This can scare users into thinking that their
reflog got truncated after 'git checkout --orphan'.

Continue walking the reflog past such creation events based on the
preceeding reflog entry's "new" value.

The test 'symbolic-ref writes reflog entry' in t1401-symbolic-ref
implicitly relies on the current behavior of the reflog walker to stop
at a root commit and thus to list only the reflog entries that are
relevant for that test.  Adjust the test to explicitly specify the
number of relevant reflog entries to be listed.

Likewise, you can ask rev-list to limit such a traversal
with `-n`, in which case we'll show only a limited set of
commits (and only the tree and commit objects directly
reachable from those commits).

But if you do both together, the results are nonsensical. We
end up limiting any fallback traversal we do to _find_ the
bitmaps, but the actual set of objects we output will be
picked arbitrarily from the union of any bitmaps we do find,
and will involve the objects of many more commits.

It's possible that somebody might want this as a "show me
what you can, but limit the amount of work you do" flag.
But as with the prior commit clamping "--count", the results
are basically non-deterministic; you'll get the values from
some commits between `n` and the total number, and you can't
tell which.

And unlike the `--count` case, we can't easily generate the
"real" value from the bitmap values (you can't just walk
back `-n` commits and subtract out the reachable objects
from the boundary commits; the bitmaps for `X` record its
total reachability, so you don't know which objects are
directly from `X` itself, which from `X^`, and so on).

So let's just fallback to the non-bitmap code path in this
case, so we always give a sane answer.

4 years agorev-list: "adjust" results of "--count --use-bitmap-index -n"
Jeff King [Fri, 3 Jun 2016 07:07:34 +0000 (03:07 -0400)]
rev-list: "adjust" results of "--count --use-bitmap-index -n"

If you ask rev-list for:

    git rev-list --count --use-bitmap-index HEAD

we optimize out the actual traversal and just give you the
number of bits set in the commit bitmap. This is faster,
which is good.

But if you ask to limit the size of the traversal, like:

    git rev-list --count --use-bitmap-index -n 100 HEAD

we'll still output the full bitmapped number we found. On
the surface, that might even seem OK. You explicitly asked
to use the bitmap index, and it was cheap to compute the
real answer, so we gave it to you.

But there's something much more complicated going on under
the hood. If we don't have a bitmap directly for HEAD, then
we have to actually traverse backwards, looking for a
bitmapped commit. And _that_ traversal is bounded by our
`-n` count.

This is a good thing, because it bounds the work we have to
do, which is probably what the user wanted by asking for
`-n`. But now it makes the output quite confusing. You might
get many values:

  - your `-n` value, if we walked back and never found a
    bitmap (or fewer if there weren't that many commits)

  - the actual full count, if we found a bitmap root for
    every path of our traversal with in the `-n` limit

  - any number in between! We might have walked back and
    found _some_ bitmaps, but then cut off the traversal
    early with some commits not accounted for in the result.

So you cannot even see a value higher than your `-n` and say
"OK, bitmaps kicked in, this must be the real full count".
The only sane thing is for git to just clamp the value to a
maximum of the `-n` value, which means we should output the
exact same results whether bitmaps are in use or not.

The test in t5310 demonstrates this by using `-n 1`.
Without this patch we fail in the full-bitmap case (where we
do not have to traverse at all) but _not_ in the
partial-bitmap case (where we have to walk down to find an
actual bitmap). With this patch, both cases just work.

I didn't implement the crazy in-between case, just because
it's complicated to set up, and is really a subset of the
full-count case, which we do cover.

test-lib: add in-shell "env" replacement

function, like test_must_fail (on some shells FOO remains
set after the function returns, and on others it does not).

We sometimes get around this by using env, like:

  test_must_fail env FOO=BAR some-program

But that only works because test_must_fail's arguments are
themselves a command which can be run. You can't run:

  env FOO=BAR test_must_fail some-program

because env does not know about our shell functions. So
there is no equivalent for test_commit, for example, and one
must resort to:

  (
    FOO=BAR
    export FOO
    test_commit
  )

which is a bit verbose.  Let's add a version of "env" that
works _inside_ the shell, by creating a subshell, exporting
variables from its argument list, and running the command.
