Windows without that, but we shouldn't put bad examples where people might
copy them. Also, reformat slightly to improve the odds that pgindent
won't go nuts on this.
This method will not catch all different ways since the locale
handling in NTFS doesn't provide an easy way to do that, but it
will hopefully solve the most common cases causing startup
problems when the backend is found in the system PATH.
Attempts to fix bug #4694.
Also, if linked against other versions than the default MSVCRT library
(for example the MSVC build which links against MSVCRT80), also update
the cache in the default MSVCRT at the same time.
This should fix the issues with setting LC_MESSAGES on the MSVC build.
Original patch from Hiroshi Inoue and Hiroshi Saito, much rewritten
by me.
the * character at the beginning of a pattern, and it does not match
subdomains.
Since this means we no longer need fnmatch, remove the imported implementation
from port, along with the autoconf check for it.

Per suggestion from Andrew Chernow, but not his patch since the underlying
code was changed to deal with return values.

the future.
Not backpatching, since it's not called anywhere today.
file; the idea is that we should clean up as much as we can, even if there's
some problem removing one file. Make the error messages a bit less misleading,
too. In passing, const-ify function arguments.
place to prevent reusing relation OIDs before next checkpoint, and DROP
DATABASE. First, if a database was dropped, bgwriter would still try to unlink
the files that the rmtree() call by the DROP DATABASE command has already
deleted, or is just about to delete. Second, if a database is dropped, and
another database is created with the same OID, bgwriter would in the worst
case delete a relation in the new database that happened to get the same OID
as a dropped relation in the old database.
To fix these race conditions:
- make rmtree() ignore ENOENT errors. This fixes the 1st race condition.
- make ForgetDatabaseFsyncRequests forget unlink requests as well.
- force checkpoint on in dropdb on all platforms
Since ForgetDatabaseFsyncRequests() is asynchronous, the 2nd change isn't
enough on its own to fix the problem of dropping and creating a database with
same OID, but forcing a checkpoint on DROP DATABASE makes it sufficient.
Per Tom Lane's bug report and proposal. Backpatch to 8.3.
on win32, because the stat() function in the runtime cannot
be trusted to always update the st_size field.
Per report and research by Sergey Zubkovsky.
The places that did, eg,
(statbuf.st_mode & S_IFMT) == S_IFDIR
were correct, but there is no good reason not to use S_ISDIR() instead,
especially when that's what the other 90% of our code does. The places
that did, eg,
(statbuf.st_mode & S_IFDIR)
were flat out *wrong* and would fail in various platform-specific ways,
eg a symlink could be mistaken for a regular file on most Unixen.
The actual impact of this is probably small, since the problem cases
seem to always involve symlinks or sockets, which are unlikely to be
found in the directories that PG code might be scanning. But it's
clearly trouble waiting to happen, so patch all the way back anyway.
(There seem to be no occurrences of the mistake in 7.4.)
value for a precision is negative, act as though precision weren't
specified at all, that is the whole .* part of the format spec should
be ignored. Our previous coding took it as .0 which is certainly
wrong. Per report from Kris Jurka and local testing.
Possibly this should be back-patched, but it would be good to get
some more testing first; in any case there are no known cases where
there's really a problem on the backend side.
by explicitly adding back the user to the DACL of the new process.
This fixes the failure case when executing as the Administrator
user, which had no permissions left at all after we dropped the
Administrators group.

SHGetFolderPath.
This removes the direct dependency on shell32.dll and user32.dll, which
eats a lot of "desktop heap" for each backend that's started. The
desktop heap is a very limited resource, causing backends to no
longer start once it's been exhausted.
We still have indirect depdendencies on user32.dll through third party
libraries, but those can't easily be removed.

Also enable translation of PG_WIN874, which certainly seems to have an
obvious translation now, though maybe it did not at the time this table's
ancestor was created.
since this will allow initdb to reject attempts to initdb in a locale
that uses such an encoding. We'll probably find out more such names
during beta ...
databases with encodings that are incompatible with the server's LC_CTYPE
locale, when we can determine that (which we can on most modern platforms,
I believe). C/POSIX locale is compatible with all encodings, of course,
so there is still some usefulness to CREATE DATABASE's ENCODING option,
but this will insulate us against all sorts of recurring complaints
caused by mismatched settings.
I moved initdb's existing LC_CTYPE-to-encoding mapping knowledge into
a new src/port/ file so it could be shared by CREATE DATABASE.
the generated files, to help Visual C++ to run these tests. The tests still
pass in VPATH and normal builds.
Patch from Magnus Hagander, editorialized by me.
FormatMessage() (This should have been in 8.2.0, patched to 8.2.X and
HEAD):
I think this problem to be complex....
http://archives.postgresql.org/pgsql-hackers/2006-11/msg00042.php
FormatMessage of windows cannot consider the encoding of the database.
However, I should try the solution now. It is necessary to clear the
problem.
Multi character-code exists together in message and log. It doesn't
consider
the data base encoding that the user intended....
The user in multi-byte country can try this.

30 seconds instead of retrying forever. Also modify xlog.c so that if
it fails to rename an old xlog segment up to a future slot, it will
unlink the segment instead. Per discussion of bug #2712, in which it
became apparent that Windows can handle unlinking a file that's being
held open, but not renaming it.
repeatedly. Now that we don't have to worry about memory leaks from
glibc's qsort, we can safely put CHECK_FOR_INTERRUPTS into the tuplesort
comparators, as was requested a couple months ago. Also, get rid of
non-reentrancy and an extra level of function call in tuplesort.c by
providing a variant qsort_arg() API that passes an extra void * argument
through to the comparison routine. (We might want to use that in other
places too, I didn't look yet.)
to performance. (A wholesale effort to get rid of strncpy should be
undertaken sometime, but not during beta.) This commit also fixes dynahash.c
to correctly truncate overlength string keys for hashtables, so that its
callers don't have to anymore.
return true for exactly the characters treated as whitespace by their flex
scanners. Per report from Victor Snezhko and subsequent investigation.
Also fix a passel of unsafe usages of <ctype.h> functions, that is, ye olde
char-vs-unsigned-char issue. I won't miss <ctype.h> when we are finally
able to stop using it.
pg_usleep at all. Instead call the replacement function in
port/win32/signal.c by that name. Avoids tricky macro-redefinition
logic and suppresses a compiler warning; furthermore it ensures that
no one can accidentally use the non-signal-aware version of pg_usleep
in a Windows backend.
I take out patch for this as a promise. This is client-build support of
MS-VC6+.
Fix for different getaddrinfo structure ordering on Win32 for IPv6.

After updating to the latest cvs, and also building most of the addons
(like PLs), the following patch is neededf for win32 + Visual C++.
* Switch to use the new win32 semaphore code
* Rename win32_open to pgwin32_open. win32_open collides with symbols
defined in Perl. MingW didn't detect ig, MSVC did. And it's a bit too
generic a name to export globally, imho...
* Python defines some partially broken #pragmas in the headers when
doing a debug build. Workaround.

places --- that risks corrupting data structures, losing sync with the
backend, etc. We now longjmp only from calls to readline, fgets, and
fread, which we assume are coded to protect themselves against interrupts
at undesirable times. This requires adding explicit tests for
cancel_pressed in long-running loops, but on the whole it's far cleaner.
Martijn van Oosterhout and Tom Lane.
o remove many WIN32_CLIENT_ONLY defines
o add WIN32_ONLY_COMPILER define
o add 3rd argument to open() for portability
o add include/port/win32_msvc directory for
system includes
