[PATCH v4 0/4] Force pipes to flush immediately on NonStop platform

[randall.s.becker]

From: "Randall S. Becker" <rsbecker@nexbridge.com>

Call setbuf(stream,NULL) to force pipe flushes not enabled by
default on the NonStop platform in wrapper.c. This may be extended
in future to a configure option.

[PATCH v4 1/4] Add tar extract install options override in installation processing.

[randall.s.becker]

From: "Randall S. Becker" <rsbecker@nexbridge.com>

Introduced TAR_EXTRACT_OPTIONS as a configuration option to change
the options of tar processing during extract. The default value is "o"
which synthesizes xof, by default.

We typically start the subject with some short token to help readers
of "git shortlog --no-merges" identify what area is being touched,
e.g. something like

Subject: [PATCH 1/4] Makefile: allow customizing tar extract options for installation

And then we order the codebase "to be like so" (or, give an order to
a patch monkey "to make the resulting code like so").
i.e. something like:

    Introduce TAR_EXTRACT_OPTIONS to allow customizing the tar
    options used when installing.  The default value is "o", which ...

What is missing from the log message is the most important thing,
though.  Everything you wrote (i.e. what build-time knob is being
added, what is tweaked and what the default is) we can read from the
patch text itself, but readers will be left wondering why anybody
would want to change "o" and change it to what else under what
circumstances to achieve what.  I am guessing something like this
might be the reason behind this change

    This allows an implementations of "tar" that lacks the 'o'
    (--no-same-owner) extract option to be used (even though the
    resulting installed versions will keep ownership of whoever
    happened to have built them, instead of being owned by 'root')

but please do not make readers guess.

Having said all that, I wonder if this "go to po/build/locale, tar
everything up and then extract it elsewhere" is truly necessary.
IOW, why isn't it sufficient to do this instead, for example?

    umask 022 && cp -r po/build/locale/. '$(DESTDIR_SQ)$(localedir_SQ)'

Drats. Can this be changed here rather than reissuing? I will sign off on
the sticky finger typo.

Hmm, I'm a bit puzzled by this patch. I may be wrong, but it
looks like it has nothing to do with the lack of the 'o' option
of tar, and more to do with adding the 'v' option to only a
single invocation of tar. There are three instances of this
kind of pattern in the Makefile, but only one has been modified.
Why?

Given the above, I suspect that (for some unknown reason), a verbose
'listing' of the locale files is required ... :-D

The "tar extraction option" thing in 1/4 is not something you use

The define is used only in my team's distribution engine and we are planning
to override the define as part of our Jenkins build of git. We do not expect
anyone else who clones git and builds on the platform to use this
capability. As a result, I did not want it to be defaulted as "ov", which is
our setting.

[PATCH v4 3/4] Bring NonStop platform definitions up to date in git-compat-util.h

[randall.s.becker]

From: "Randall S. Becker" <rsbecker@nexbridge.com>

Add correct FLOSS (NonStop platform emulation) definitions into
git-compat-util.h to allow correct emulation of non-platform
behaviour. Also added NSIG definition that is not explicitly
supplied in signal.h on platform.

The above adds a conditional no-op?  That's confusing...

We are trying to make PUT work with git on NonStop. I can't tell you how
much of a pain it is. This is a placeholder for others (outside our group)
to know where to muck. I can remove it if you don't want it there.

It is OK as long as it was done on purpose.  I was just making sure
that this was an unfinished WIP sent by mistake before proofreading.

Obviously, I was trying to make sure it was *NOT* an incomplete
state you did not intend to send ;-)

Absolutely definitely positively on purpose and when it we get PUT working
in FLOSS, this is *so* going to happen. :-) 

[PATCH v4 4/4] Add intptr_t and uintptr_t to regcomp.c for NonStop platform.

[randall.s.becker]

From: "Randall S. Becker" <rsbecker@nexbridge.com>

Fix missing intptr_t on NonStop in compat/regex/regcomp.c wrapped
using the __TANDEM guard define. This is done because
git-compat-util.h cannot be cleanly included into this file
without additional compile errors.
