As mentioned in https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/ GitHub workflows should avoid using Actions that use Node.js 12 and instead upgrade to versions of those Actions that use Node.js 16. So let's do that. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
We only build once in CI, so dependency tracking isn't needed. This saves 3-4 minutes in CI.
We just disabled the code that skips environment variables whose values are empty. However, this code was introduced a long time ago into Cygwin in d6b1ac7 (* environ.cc (build_env): Don't put an empty environment variable into the environment. Optimize use of "len". * errno.cc (ERROR_MORE_DATA): Translate to EMSGSIZE rather than EAGAIN., 2006-09-07), seemingly without any complaints. Meaning: There might very well be use cases out there where it makes sense to skip empty-valued environment variables. Therefore, it seems like a good idea to have a "knob" to turn it back on. With this commit, we introduce such a knob: by setting `noemptyenvvalues` the `MSYS` variable (or appending it if that variable is already set), users can tell the MSYS2 runtime to behave just like in the olden times.

With this commit, you can call MSYS=noemptyenvvalues my-command and it does what is expected: to pass no empty-valued environment variables to `my-command`. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
When calling `cygpath -u C:/msys64/` in an MSYS2 setup that was installed into `C:/msys64/`, the result should be `/`, not `//`. Let's ensure that we do not append another trailing slash if the converted path already ends in a slash.

This solves redefinition of FILE_CS_FLAG_CASE_SENSITIVE_DIR in winnt.h
and fixes the following compiler errors
ntdll.h:523:3: error: expected identifier before numeric constant
523 | FILE_CS_FLAG_CASE_SENSITIVE_DIR = 0x01
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ntdll.h:522:1: note: to match this ‘{’

(cherry picked from commit 3bee682)
GCC 13 (and maybe 12, too), warn about pointers used after `free()`. In `nlsfuncs.cc`, they are used on purpose, though, in `rebase_locale_buf()`, to adjust pointers that were invalidated because of a `realloc()` (not a `free()`, actually). So let's shush GCC about those instances. However, we must be careful only to do that with GCC >= 12 because older versions would complain about an unknown warning...

Whoopsie. I meant to merge this before git-for-windows/MSYS2-packages#138. |
|
This is something I have thought about for msys2/msys2-runtime. MSYS2 does still have https://packages.msys2.org/base/msys2-runtime-3.3. Would it make sense to do this "upstream" too? |

After merging git-for-windows/MSYS2-packages#136, I realized that we had not kept the v3.3 branch up to date. So I went through the range-diff between the v3.3 and the v3.4 patches and cherry-picked anything from the latter that struck me as needing to be backported to the former.
