discussion on pgsql-hackers-win32 list. Documentation still needs to
be tweaked --- I'm not sure how to refer to the APPDATA folder in
user documentation.
consistent. On Unix we now always consult getpwuid(); $HOME isn't used
at all. On Windows the code currently consults $USERPROFILE, or $HOME
if that's not defined, but I expect this will change as soon as the win32
hackers come to a consensus. Nothing done yet about changing the file
names used underneath $USERPROFILE.
subroutine that can hide platform dependencies. The WIN32 path is still
a stub, but I await a fix from one of the win32 hackers.
Also clean up unnecessary #ifdef WIN32 ugliness in a couple of places.
share lock on a buffer being written out before releasing BufMgrLock in
the BufferAlloc code path; if we do it later we might block on someone
who's re-pinned the buffer. I believe this is only an issue for BufferAlloc
and not the other places that call FlushBuffer. BufferSync must continue
to do it the old way since it may well be trying to write buffers that
other backends have pinned; but it should not be holding any conflicting
locks. FlushRelationBuffers is okay since it's got exclusive lock at the
relation level.
Also performed an initial run through of upgrading our Copyright date to
extend to 2005 ... first run here was very simple ... change everything
where: grep 1996-2004 && the word 'Copyright' ... scanned through the
generated list with 'less' first, and after, to make sure that I only
picked up the right entries ...
to shared memory as soon as possible, ie, right after read_backend_variables.
The effective difference from the original code is that this happens
before instead of after read_nondefault_variables(), which loads GUC
information and is apparently capable of expanding the backend's memory
allocation more than you'd think it should. This should fix the
failure-to-attach-to-shared-memory reports we've been seeing on Windows.
Also clean up a few bits of unnecessarily grotty EXEC_BACKEND code.
that is, files are sought in the same directory as the referencing file.
Also allow absolute paths in @file constructs. Improve documentation
to actually say what is allowed in an included file.
executable file isn't itself a symlink. We still need to run the
algorithm so that any directory symlinks in the path to the
executable are replaced by a true path. Noticed this on seeing
pg_config give me a completely wrong answer for --pkglibdir when
I called it through a symlink to the installation bindir.
the remainder of the current clog page during system startup. While
this was a good idea, it turns out the code fails if nextXid is
exactly at a page boundary, because we won't have created the "current"
clog page yet in that case. Since the page will be correctly zeroed
when we execute the first transaction on it, the solution is just to
do nothing when exactly at a page boundary. Per trouble report from
Dave Hartwig.
