New infrastructure is added which creates a set number of workers
(threads on Windows, forked processes on Unix). Jobs are then
handed out to these workers by the master process as needed.
pg_restore is adjusted to use this new infrastructure in place of the
old setup which created a new worker for each step on the fly. Parallel
dumps acquire a snapshot clone in order to stay consistent, if
available.
The parallel option is selected by the -j / --jobs command line
parameter of pg_dump.

This appears to cause some intermittent file system problems
on Windows 8. Instead, set up the old data directory in its
intended final location to start with.

I had thought we weren't using this version of pqsignal() at all on
Windows, but that's wrong --- initdb is using it (and coping with the
POSIX-ish semantics of bare signal() :-(). So allow the file to be
built in WIN32+FRONTEND case, and add it to the MSVC build logic.

They can include sys/sdt.h from SystemTap, which itself contains C++
code and so won't compile with a C++ compiler under extern "C" linkage.
|
|
The new file in src/port needs to be listed in Mkvcbuild.pm as well.
|
|
The previous commit didn't work on MSVC editions earlier than
Visual Studio 2011, apparently. This works by copying files into the
contrib directory, and making provision to clean them up, which should
work on all editions.

This enables non-backend code, such as pg_xlogdump, to use it easily.
The previous location, in src/backend/catalog/catalog.c, made that
essentially impossible because that file depends on many backend-only
facilities; so this needs to live separately.
|
|
Per buildfarm.
|
|
The previous order of steps didn't literally work, because git clean
-fdx would delete the downloaded typedefs.list. Also, pgindent needs to
be called with a path when one is in at the top of the build tree.

libpgcommon is a new static library to allow sharing code among the
various frontend programs and backend; this lets us eliminate duplicate
implementations of common routines. We avoid libpgport, because that's
intended as a place for porting issues; per discussion, it seems better
to keep them separate.
The first use case, and the only implemented by this patch, is pg_malloc
and friends, which many frontend programs were already using.
At the same time, we can use this to provide palloc emulation functions
for the frontend; this way, some palloc-using files in the backend can
also be used by the frontend cleanly. To do this, we change palloc() in
the backend to be a function instead of a macro on top of
MemoryContextAlloc(). This was previously believed to cause loss of
performance, but this implementation has been tweaked by Tom and Andres
so that on modern compilers it provides a slight improvement over the
previous one.
This lets us clean up some places that were already with
localized hacks.
Most of the pg_malloc/palloc changes in this patch were authored by
Andres Freund. Zoltán Böszörményi also independently provided a form of
that. libpgcommon infrastructure was authored by Álvaro.

This ensure the version number increases over time. The first three digits
in the version number is still set to the actual PostgreSQL version
number, but the last one is intended to be an ever increasing build number,
which previosly failed when it changed between 1, 2 and 3 digits long values.

Get rid of the fundamentally indefensible assumption that "long long int"
exists and is exactly 64 bits wide on every platform Postgres runs on.
Instead let the configure script select the type to use for "pg_int64".
This is a bit of a pain in the rear since we do not want to pollute client
namespace with all the random symbols that pg_config.h defines; instead
we have to create a separate generated header file, "pg_config_ext.h".
But now that the infrastructure is there, we might have the ability to
add some other stuff that's long been wanting in this area.

This makes the naming inside plpgsql consistent and distinguishes the
file from the backend's gram.y file. It will also allow easier
refactoring of the bison make rules later on.

checking pg_upgrade.

This script is a bit slow, but still it only takes a fraction of the time
the bison run does, so the overhead doesn't seem intolerable. And we
definitely need some mechanical aid here, because people keep missing
the need to add new keywords to the appropriate keyword-list production.
While at it, I moved check_keywords.pl from src/tools into
src/backend/parser where it's actually used, and did some very minor
cleanup on the script.

This follows recent addition of Windows/Mingw testing.
Backpatch to Release 9.2 so we can get some buildfarm testing

This was removed in commit cd004067742ee16ee63e55abfb4acbd5f09fbaab,
we're not quite sure why, but there have been reports of crashes due
to AS Perl being built with it when we are not, and it certainly
seems like the right thing to do. There is still some uncertainty
as to why it sometimes fails and sometimes doesn't.

extended by Andrew Dunstan.

We seem to have a rough policy that our Perl scripts should work with
Perl 5.8, so make this one do so. Main change is to not use the newfangled
\h character class in regexes; "[ \t]" is a serviceable replacement.
