Conversion functions were previously marked as parallel-unsafe, since
that is the default, but in fact they are safe. Parallel-safe
functions defined in pg_proc.h and redefined in system_views.sql were
ending up as parallel-unsafe because the redeclarations were not
marked PARALLEL SAFE. While editing system_views.sql, mark ts_debug()
parallel safe also.

In commit 921191912c I claimed that we weren't testing encoding
conversion functions, but further poking around reveals that we did
have an equivalent though hard-wired set of tests in conversion.sql.
AFAICS there is no advantage to doing it like that as compared to letting
the catalog contents drive the test, so let the opr_sanity addition stand
and remove the now-redundant tests in conversion.sql.
Also, remove some infrastructure in src/backend/utils/mb/conversion_procs
for building conversion.sql's list of tests. That was unmaintained, and
had not corresponded to the actual contents of conversion.sql since 2007
or perhaps even further back.
Previously, each subroutine in initdb fired up its own standalone backend
session. Over time we'd grown as many as fifteen of these sessions,
and the cumulative startup and shutdown work for them was getting pretty
noticeable. Combining things so that all these steps share a single
backend session cuts a good 10% off the total runtime of initdb, more
if you're not fsync'ing.
The main stumbling block to doing this before was that some of the sessions
were run with -j and some not. The improved definition of -j mode
implemented by my previous commit makes it possible to fix that by running
all the post-bootstrap steps with -j; we just have to use double instead of
single newlines to end command strings. (This is only absolutely necessary
around the VACUUM and CREATE DATABASE steps, since those can't be run in a
transaction block. But it seems best to make them all use double newlines
so that the commands remain separate for error-reporting purposes.)
A minor disadvantage is that since initdb can't tell how much of its
output the backend has executed, we can no longer have the per-step
progress reporting initdb used to print. But things are fast enough
nowadays that that's not really all that useful anyway.
In passing, add more const decoration to some of the static arrays in
initdb.c.
Replace for loops in makefiles with proper dependencies. Parallel
make can now span across directories. Also, make -k and make -q work
properly.
GNU make 3.80 or newer is now required.
tarballs under 100 characters. This should avoid failures with certain
untarring tools (WinZip and Midnight Commander have been mentioned as
likely suspects). Per my proposal of yesterday.
catversion bumped since the initial contents of pg_proc change.
Update install-sh to that from Autoconf 2.63, plus our Darwin-specific
changes (which I simplified a bit). install-sh is now able to install
multiple files in one run, so we could simplify our makefiles sometime.
install-sh also now has a -d option to create directories, so we don't need
mkinstalldirs anymore.
Use AC_PROG_MKDIR_P in configure.in, so we can use mkdir -p when available
instead of install-sh -d. For consistency with the rest of the world,
the corresponding make variable has been renamed from $(mkinstalldirs) to
$(MKDIR_P).
Test coverage support now covers the entire source tree, including
contrib, instead of just src/backend. In a related but independent
development, the commands make coverage and make coverage-html can be run
in any directory.
This turned out to be much easier than feared. Besides a few ad hoc fixes
to pass the make target down the tree, change all affected makefiles to
list their directories in the SUBDIRS variable, changed from variants like
DIRS and WANTED_DIRS. MSVC build fix was attempted as well.
errors in any commands, including in various clean targets that have so far
been handled inconsistently. make -i is available to ignore all errors in
a consistent and official way.
up a bunch of the support utilities.
In src/backend/utils/mb/Unicode remove nearly duplicate copies of the
UCS_to_XXX perl script and replace with one version to handle all generic
files. Update the Makefile so that it knows about all the map files.
This produces a slight difference in some of the map files, using a
uniform naming convention and not mapping the null character.
In src/backend/utils/mb/conversion_procs create a master utf8<->win
codepage function like the ISO 8859 versions instead of having a separate
handler for each conversion.
There is an externally visible change in the name of the win1258 to utf8
conversion. According to the documentation notes, it was named
incorrectly and this changes it to a standard name.
Running the Unicode mapping perl scripts has shown some additional mapping
changes in koi8r and iso8859-7.
output area as INTERNAL not CSTRING. This is to prevent people from
calling the functions by hand. This is a permanent solution for the
back branches but I hope it is just a stopgap for HEAD.
'make install'; there are enough of 'em that this slowed down the make
noticeably. Ensure that 'all' is the default make target in all these
directories (defaulting to 'make install' is surprising and dangerous
IMHO). Fix a couple small typos.
with OPAQUE, as per recent pghackers discussion. I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...
