2 years agouserdiff-cpp: back out the digit-separators in numbers
Johannes Sixt [Sun, 24 Oct 2021 09:56:43 +0000 (11:56 +0200)] 
userdiff-cpp: back out the digit-separators in numbers

The implementation of digit-separating single-quotes introduced a
note-worthy regression: the change of a character literal with a
digit would splice the digit and the closing single-quote. For
example, the change from 'a' to '2' is now tokenized as
'[-a'-]{+2'+} instead of '[-a-]{+2+}'.

The options to fix the regression are:

- Tighten the regular expression such that the single-quote can only
  occur between digits (that would match the official syntax).

- Remove support for digit separators.

I chose to remove support, because

- I have not seen a lot of code make use of digit separators.

- If code does use digit separators, then the numbers are typically
  long. If a change in one of the segments occurs, it is actually
  better visible if only that segment is highlighted as the word
  that changed instead of the whole long number.

This choice does introduce another minor regression, though, which
is highlighted in the test case: when a change occurs in the second
or later segment of a hexadecimal number where the segment begins
with a digit, but also has letters, the segment is mistaken as
consisting of a number and an identifier. I can live with that.

mergetools/xxdiff: prevent segfaults from stopping difftool

Users often use "git difftool HEAD^" to review their work, and have
"mergetool.prompt" set to false so that difftool does not prompt them
before diffing each file.

This is very convenient because users can see all their diffs by
reviewing the xxdiff windows one at a time.

A problem occurs when xxdiff encounters some binary files.
It can segfault and return exit code 128, which is special-cased
by git-difftool-helper as being an extraordinary situation that
aborts the process.

Suppress the exit code from xxdiff in its diff_cmd() implementation
when we see exit code 128 so that the GIT_EXTERNAL_DIFF loop continues
on uninterrupted to the next file rather than aborting when it
encounters the first binary file.

2 years agoci(windows): ensure that we do not pick up random executables

ci(windows): ensure that we do not pick up random executables

On the Windows build agents, a lot of programs are installed, and added
to the PATH automatically.

One such program is Git for Windows, and due to the way it is set up,
unfortunately its copy of `gpg.exe` is also reachable via the PATH.

This usually does not pose any problems. To the contrary, it even allows
us to test the GPG parts of Git's test suite even if `gpg.exe` is not
delivered as part of `git-sdk-64-minimal`, the minimal subset of Git for
Windows' SDK that we use in the CI builds to compile Git.

However, every once in a while we build a new MSYS2 runtime, which means
that there is a mismatch between the copy in `git-sdk-64-minimal` and
the copy in C:\Program Files\Git\usr\bin. When that happens we hit the
dreaded problem where only one `msys-2.0.dll` is expected to be in the
PATH, and things start to fail.

Let's avoid all of this by restricting the PATH to the minimal set. This
is actually done by `git-sdk-64-minimal`'s `/etc/profile`, and we just
have to source this file manually (one would expect that it is sourced
automatically, but the Bash steps in Azure Pipelines/GitHub workflows
are explicitly run using `--noprofile`, hence the need for doing this
explicitly).
