That looks like a part of the new 'instead of run_command("cp -R"),
let's borrow code from somewhere and do that ourselves' in the
nd/worktree-move topic.

The offending part is this:

+   if (S_ISBLK(source_stat.st_mode) ||
+   S_ISCHR(source_stat.st_mode) ||
+   S_ISSOCK(source_stat.st_mode) ||
+   S_ISFIFO(source_stat.st_mode)) {
+   if (mknod(dest, source_stat.st_mode, source_stat.st_rdev) < 0)
+   return error_errno(_("can't create '%s'"), dest);
+   } else
+   return error(_("unrecognized file '%s' with mode %x"),
+source, source_stat.st_mode);

I think all of this is meant to be used to copy what is in the
working tree, and what is in the working tree is meant to be tracked
by Git, none of the four types that triggers mknod() would be
relevant for our purpose.  The simplest and cleanest would be to
make the above to return error("unsupported filetype").

I do not mind run_command("cp -R") and get rid of this code
altogether; that might be a more portable and sensible approach.

Well, I should add that the test suite does not take 3 hours to run for
`pu` these days.

It used to time out after four hours until two days ago (I think; I was a
bit too busy with other CI work to pay close attention to the constantly
failing `pu` job, with quite a few failing `next`s and even a couple of
failing `master`s thrown in).

As of two days ago, the test suite takes no time at all. The build already
fails (which makes me wonder why a couple of patch series I contributed
had such a hard time getting into `pu` when they compiled and tested
just fine, whereas some obviously non-building stuff gets into `pu`
already, makes no sense to me).

This is the offending part from last night's build:

[+cc Pranit]

Yep, I had a quick squint, and it looks like the compiler is correct.
It should be complaining about the 'bad_syn' variable for exactly the
same reason: namely, whenever the if condition is true, the only exit
from that block is via 'goto finish' which bypasses the initialisation
of 'good_syn' and 'bad_syn'.

No patch this time, but it simply requires those variables to be
initialised to NULL in their declarations. :-D

Yep, the idea being to catch these simple problems before the topic

The purpose of 'pu' is none of the above, but its intended effect
for people other than me is (4).  It is primarily meant as a way for
me to avoid having to go back to the mailing list archive to find
topics that I felt that were potentially interesting but not yet
ready and may want to get commented on later.  When queued on 'pu',
it is not unusual that I haven't really looked at the patches yet,
and it is not surprising if it does not build on any platform.

When queued to 'pu', the reason of the initial "not yet ready"
assessment may not have anything to do with the quality of the
patches but based on the phase of the development (e.g. during a
feature-freeze, it is less efficient use of our time to take new
topics to 'next'), so what was queued on 'pu' may get merged to
'next' without any update, after getting looked at by me or by
other people and deemed to be worth trying out.

Dscho's mention of 'still times out' may be an indiciation that
something unspecified on 'pu' is not ready to be merged to 'next',
but blocking all of 'pu' with a blanket statement is not useful,
and that was where my response comes from.  We need to know more
to say "this particular topic is not ready", so that we can unblock
other innocent topics.

I'd have answered differently, though I think in the end we agree on the
outcome.

I think the only thing that matters is (4). It _usually_ builds and
passes all tests, but not always. But the point is that nobody should
care in particular about "pu". What we care about is whether the
individual topics will build and pass before they are merged to master
(or even "next").

So "pu" is a tool, because you can test all of the topics at once and
find out early if there are any problems. And it's good to investigate
problems there before topics hit next (though they are also often caught
in review, or by people trying the broken topic on their various
platforms, or sometimes Junio even pushes out a known-broken state in pu
and mentions it in "What's cooking").

So yes, it should do all of those things, but we don't necessarily
expect that it will never be broken. That's expected to happen from time
to time, and the purpose of the branch. With respect to Lars' original
point:

The next step is to make sure that the topic author is aware (in this
case, one assumes it's pb/bisect).

Better still is to make a patch that can either be applied on top, or
squashed as appropriate. I know that Ramsay Jones does this, for
example, with some of his sparse-related checks, and I'm pretty sure
from the turnaround-time that he runs it against "pu".

All commits should work on all platforms - in the ideal world there is no 
problem.

>From time to time things sneak in, which are not portable.
(in the sense that not all "supported" compile/run tests without breakages)

And if everybody reports breakages and problems found on the pu
branch, there is a good chance that they don't reach next or master.

Does this make sense ?

What is the goal for 'pu'?

(1) Builds clean on all platforms + passes all tests
(2) Builds clean on all platforms
(3) Builds clean on Linux
(4) Just makes new topics easily available to a broader audience

My understanding was always (4) but the discussion above sounds 
more like (1) or (2)?

Earlier you said 'pu' did even not build, but do we know where this
"still times out" comes from?  As long as I don't merge anything
prematurely, which I need to be careful about, it shouldn't impact
the upcoming release, but we'd need to figure it out before moving

Apparently it does because the CI jobs for `master` and for `next` pass.
The one for `pu` still times out, of course.

So on reading your original I wondered why you did not need to use the
";", and that explains it. But wow, it's subtle.

I don't know what people typically write in the wild, and if it's worth
actually testing explicitly the ";" case. I'll leave that to Windows
people to debate.

[PATCH] t0021, t5615: use $PWD instead of $(pwd) in PATH-like shell variables

[Johannes Sixt]

We have to use $PWD instead of $(pwd) because on Windows the latter
would add a C: style path to bash's Unix-style $PATH variable, which
becomes confused by the colon after the drive letter. ($PWD is a
Unix-style path.)

In the case of GIT_ALTERNATE_OBJECT_DIRECTORIES, bash on Windows
assembles a Unix-style path list with the colon as separators. It
converts the value to a Windows-style path list with the semicolon as
path separator when it forwards the variable to git.exe. The same
confusion happens when bash's original value is contaminated with
Windows style paths.

When the MSYS program such as bash invokes a non-MSYS program, it
translates the Unix-style paths in arguments and environment variables
to Windows stlye. We only have to ensure that we inject only Unix-style
paths in these places so as not to confuse the conversion algorithm.
Most of the time, we do not have to worry.

On the other hand, when we write a path to a file that git.exe consumes
or receive a path from git.exe, i.e., when the path travels through
stdout and stdin, no automatic translation happens (which is quite
understandable), and we have do the translation explicitly. An example
for such a case is when we write a .git/info/alternates file via the
shell.

Here it is. I had proposed the t0021 part earlier, but it fell through
the cracks during the temporary maintainer change.
