5 years agomerge-recursive: fix the fix to the diff3 common ancestor label
Elijah Newren [Mon, 7 Oct 2019 15:52:11 +0000 (08:52 -0700)] 
merge-recursive: fix the fix to the diff3 common ancestor label

In commit 8e4ec337 ("merge-recursive: fix the diff3 common ancestor
label for virtual commits", 2019-10-01), which was a fix to commit
743474cbfa8b ("merge-recursive: provide a better label for diff3
common ancestor", 2019-08-17), the label for the common ancestor was
changed from always being

         "merged common ancestors"

to instead be based on the number of merge bases and whether the merge
base was a real commit or a virtual one:

    >=2: "merged common ancestors"
      1, via merge_recursive_generic: "constructed merge base"
      1, otherwise: <abbreviated commit hash>
      0: "<empty tree>"

The handling for "constructed merge base" worked by allowing
opt->ancestor to be set in merge_recursive_generic(), so we paid
attention to the setting of that variable in merge_recursive_internal().
Now, for the outer merge, the code flow was simply the following:

ancestor_name = "merged merge bases"
loop over merge_bases: merge_recursive_internal()

The first merge base not needing recursion would determine its own
ancestor_name however necessary and thus run

ancestor_name = $SOMETHING
empty loop over merge_bases...
opt->ancestor = ancestor_name
        merge_trees_internal()

Now, the next set of merge_bases that would need to be merged after this
particular merge had completed would note that opt->ancestor has been
set to something (to a local ancestor_name variable that has since been
popped off the stack), and thus it would run:

... else if (opt->ancestor) {
ancestor_name = opt->ancestor;  /* OOPS! */
        loop over merge_bases: merge_recursive_internal()
        opt->ancestor = ancestor_name
        merge_trees_internal()

This resulted in garbage strings being printed for the virtual merge
bases, which was visible in git.git by just merging commit b744c3af07
into commit 6d8cb22a4f.  There are two ways to fix this: set
opt->ancestor to NULL after using it to avoid re-use, or add a
!opt->priv->call_depth check to the if block for using a pre-defined
opt->ancestor.  Apply both fixes.

5 years agotest-tool run-command: learn to run (parts of) the testsuite

test-tool run-command: learn to run (parts of) the testsuite

Git for Windows jumps through hoops to provide a development environment
that allows to build Git and to run its test suite. To that end, an
entire MSYS2 system, including GNU make and GCC is offered as "the Git
for Windows SDK". It does come at a price: an initial download of said
SDK weighs in with several hundreds of megabytes, and the unpacked SDK
occupies ~2GB of disk space.

A much more native development environment on Windows is Visual Studio.
To help contributors use that environment, we already have a Makefile
target `vcxproj` that generates a commit with project files (and other
generated files), and Git for Windows' `vs/master` branch is
continuously re-generated using that target.

The idea is to allow building Git in Visual Studio, and to run
individual tests using a Portable Git.

The one missing thing is a way to run the entire test suite: neither
`make` nor `prove` are required to run Git, therefore Git for Windows
does not support those commands in the Portable Git.

To help with that, add a simple test helper that exercises the
`run_processes_parallel()` function to allow for running test scripts in
parallel (which is really necessary, especially on Windows, as Git's
test suite takes such a long time to run).

This will also come in handy for the upcoming change to our Azure
Pipeline: we will use this helper in a Portable Git to test the Visual
Studio build of Git.

The return value of that function is 0 both for variables that are

two cases, one has to call `GetLastError()`, whose return value is
`ERROR_ENVVAR_NOT_FOUND` and `ERROR_SUCCESS`, respectively.

Except that it is not actually set to `ERROR_SUCCESS` in the latter
case, apparently, but the last error value seems to be simply unchanged.

To work around this, let's just re-set the last error value just before
inspecting the environment variable.

This fixes a problem that triggers failures in t3301-notes.sh (where we
try to override config settings by passing empty values for certain
environment variables).

This problem is hidden in the MINGW build by the fact that older
MSVC runtimes (such as the one used by MINGW builds) have a `calloc()`
that re-sets the last error value in case of success, while newer

function.

msvc: ignore some libraries when linking

To build with MSVC, we "translate" GCC options to MSVC options, and part
of those options refer to the libraries to link into the final
executable. Currently, this part looks somewhat like this on Windows:

-lcurl -lnghttp2 -lidn2 -lssl -lcrypto -lssl -lcrypto -lgdi32
-lcrypt32 -lwldap32 -lz -lws2_32 -lexpat

Some of those are direct dependencies (such as curl and ssl) and others
are indirect (nghttp2 and idn2, for example, are dependencies of curl,
but need to be linked in for reasons).

We already handle the direct dependencies, e.g. `-liconv` is already
handled as adding `libiconv.lib` to the list of libraries to link
against.

Let's just ignore the remaining `-l*` options so that MSVC does not have
to warn us that it ignored e.g. the `/lnghttp2` option. We do that by

msvc: avoid using minus operator on unsigned types

MSVC complains about this with `-Wall`, which can be taken as a sign
that this is indeed a real bug. The symptom is:

C4146: unary minus operator applied to unsigned type, result
still unsigned

Let's avoid this warning in the minimal way, e.g. writing `-1 -
<unsigned value>` instead of `-<unsigned value> - 1`.

Note that the change in the `estimate_cache_size()` function is
needed because MSVC considers the "return type" of the `sizeof()`
operator to be `size_t`, i.e. unsigned, and therefore it cannot be
negated using the unary minus operator.

Even worse, that arithmetic is doing extra work, in vain. We want to
calculate the entry extra cache size as the difference between the
size of the `cache_entry` structure minus the size of the
`ondisk_cache_entry` structure, padded to the appropriate alignment
boundary.

To that end, we start by assigning that difference to the `per_entry`
variable, and then abuse the `len` parameter of the
`align_padding_size()` macro to take the negative size of the ondisk
entry size. Essentially, we try to avoid passing the already calculated
difference to that macro by passing the operands of that difference
instead, when the macro expects operands of an addition:

#define align_padding_size(size, len) \
((size + (len) + 8) & ~7) - (size + len)

Currently, we pass A and -B to that macro instead of passing A - B and
0, where A - B is already stored in the `per_entry` variable, ready to
be used.

This is neither necessary, nor intuitive. Let's fix this, and have code
that is both easier to read and that also does not trigger MSVC's
warning.

While at it, we take care of reporting overflows (which are unlikely,
but hey, defensive programming is good!).

We _also_ take pains of casting the unsigned value to signed: otherwise,
the signed operand (i.e. the `-1`) would be cast to unsigned before
doing the arithmetic.
