If postmaster is launched with a restricted security token, with the
"Log in as Service" privilege explicitly removed, the token will contain
SECURITY_SERVICE_RID with the SE_GROUP_USE_FOR_DENY_ONLY flag, and without
the SE_GROUP_ENABLED flag. pgwin32_is_service() was fooled by that, and
thought that it's running as a service. Fix to check for the
SE_GROUP_ENABLED flag, like we do in pgwin32_is_admin().
Patch by Michael Paquier, per Breen Hagan's report and analysis. Backpatch
to all supported versions.

We weren't terribly consistent about whether to call Apple's OS "OS X"
or "Mac OS X", and the former is probably confusing to people who aren't
Apple users. Now that Apple has rebranded it "macOS", follow their lead
to establish a consistent naming pattern. Also, avoid the use of the
ancient project name "Darwin", except as the port code name which does not
seem desirable to change. (In short, this patch touches documentation and
comments, but no actual code.)
I didn't touch contrib/start-scripts/osx/, either. I suspect those are
obsolete and due for a rewrite, anyway.
I dithered about whether to apply this edit to old release notes, but
those were responsible for quite a lot of the inconsistencies, so I ended
up changing them too. Anyway, Apple's being ahistorical about this,
so why shouldn't we be?

When configured with --enable-tap-tests, "make install" will now install
the Perl support files for TAP testing where PGXS will find them.
This allows extensions to rely on $(prove_check) even when being built
out-of-tree. Back-patch to 9.4 where we first started to support TAP
testing, to reduce the number of cases extension makefiles need to
consider.

Faulty AND/OR nesting in the WHERE clause of getFuncs' SQL query led to
dumping range constructor functions if they are part of an extension
and we're in binary-upgrade mode. Actually, we don't want to dump them
separately even then, since CREATE TYPE AS RANGE will create the range's
constructor functions regardless. Per report from Andrew Dunstan.
It looks like this mistake was introduced by me, in commit b985d4877, in
perhaps-overzealous refactoring to reduce code duplication. I'm suitably
embarrassed.

We must test GetLastError() even when CreateFileMapping() returns a
non-null handle. If that value were left over from some previous system
call, we might be fooled into thinking the segment already existed.
Experimentation on Windows 7 suggests that CreateFileMapping() clears
the error code on success, but it is not documented to do so, so let's
not rely on that happening in all Windows releases.

Commits 470d886c3 et al intended to fix the problem that the postmaster
selected the same "random" DSM control segment ID on every start. But
using PostmasterRandom() for that destroys the intended property that the
delay between random_start_time and random_stop_time will be unpredictable.
(Said delay is probably already more predictable than we could wish, but
that doesn't mean that reducing it by a couple orders of magnitude is OK.)
Revert the previous patch and add a comment warning against misuse of
PostmasterRandom. Fix the original problem by calling srandom() early in
PostmasterMain, using a low-security seed that will later be overwritten
by PostmasterRandom.

Fix for transformOnConflictClause().
Author: Tomonari Katsumata
|

Past refactorings have removed all but one reference to SizeOfIptrData
(and that one place was in a pretty noncritical spot). Since nobody's
complained, it seems probable that there are no supported compilers
that don't think sizeof(ItemPointerData) is 6. If there are, we're
wasting MAXALIGN per heap tuple anyway, so it's rather silly to worry
about whether we can shave space in places like WAL records.

ExecInitCteScan supposed that it didn't have to do anything to the extra
tuplestore read pointer it gets from tuplestore_alloc_read_pointer.
However, it needs this read pointer to be positioned at the start of the
tuplestore, while tuplestore_alloc_read_pointer is actually defined as
cloning the current position of read pointer 0. In normal situations
that accidentally works because we initialize the whole plan tree at once,
before anything gets read. But it fails in an EvalPlanQual recheck, as
illustrated in bug #14328 from Dima Pavlov. To fix, just forcibly rewind
the pointer after tuplestore_alloc_read_pointer. The cost of doing so is
negligible unless the tuplestore is already in TSS_READFILE state, which
wouldn't happen in normal cases. We could consider altering tuplestore's
API to make that case cheaper, but that would make for a more invasive
back-patch and it doesn't seem worth it.
This has been broken probably for as long as we've had CTEs, so back-patch
to all supported branches.

Add tests for consistent support of connection strings in frontend
programs as well as proper handling of unusual characters in database
and user names. These tests were developed for the issues of
CVE-2016-5424.
To allow testing of names with spaces, change the pg_regress
command-line options --create-role and --dbname to split their arguments
by comma only, not space or comma as before. Only commas were actually
used in existing uses.

Move the updating of the control file to "in production" status until
the point where WAL writes are allowed. Before, there could be a
significant gap between the control file update and write transactions
actually being allowed. This makes it more reliable to use the control
status to verify the end of a promotion.

pg_ctl used to determine whether a server was in standby mode by looking
for a recovery.conf file. With this change, it instead looks into
pg_control, which is potentially more accurate. There are also
occasional discussions about removing recovery.conf, so this removes one

The way "latency average" was printed was differently if it was calculated
from the overall run time or was measured on a per-transaction basis.
Also, the per-script weight is a test parameter, rather than a result, so
use the "weight: %f" style for that.
Backpatch to 9.6, since the inconsistency on "latency average" was
introduced there.

When win32security.c was moved from src/backend/port/win32/security.c,
the message writing function was changed from write_stderr to log_error,
but nls.mk was not updated. We could add log_error to GETTEXT_TRIGGERS,
but it's also used in src/common/exec.c in a different way and that
would create some confusion or a larger patch. For now, just put an
explicit translation marker onto the strings that were previously
translated.

Otherwise, every startup gets the same "random" value, which is
definitely not what was intended.
|
|
Otherwise, attempts to run multiple postmasters running on the same
machine may fail, because Windows sometimes returns ERROR_ACCESS_DENIED
rather than ERROR_ALREADY_EXISTS when there is an existing segment.
Hitting this bug is much more likely because of another defect not
fixed by this patch, namely that dsm_postmaster_startup() uses
random() which returns the same value every time. But that's not
a reason not to fix this.

This function has no direct callers at present, but it's convenient for
manual use in a debugger, rather than having to inspect memory and do
bit-counting in your head.
In passing, get rid of useless outBitmapset() wrapper around

LibreSSL defines OPENSSL_VERSION_NUMBER to claim that it is version 2.0.0,
but it doesn't have the functions added in OpenSSL 1.1.0. Add autoconf
checks for the individual functions we need, and stop relying on
OPENSSL_VERSION_NUMBER.
Backport to 9.5 and 9.6, like the patch that broke this. In the
back-branches, there are still a few OPENSSL_VERSION_NUMBER checks left,
to check for OpenSSL 0.9.8 or 0.9.7. I left them as they were - LibreSSL
has all those functions, so they work as intended.

Changes needed to build at all:
- Check for SSL_new in configure, now that SSL_library_init is a macro.
- Do not access struct members directly. This includes some new code in
pgcrypto, to use the resource owner mechanism to ensure that we don't
leak OpenSSL handles, now that we can't embed them in other structs
anymore.
- RAND_SSLeay() -> RAND_OpenSSL()
Changes that were needed to silence deprecation warnings, but were not
strictly necessary:
- RAND_pseudo_bytes() -> RAND_bytes().
- SSL_library_init() and OpenSSL_config() -> OPENSSL_init_ssl()
- ASN1_STRING_data() -> ASN1_STRING_get0_data()
- DH_generate_parameters() -> DH_generate_parameters()
- Locking callbacks are not needed with OpenSSL 1.1.0 anymore. (Good
riddance!)
Also change references to SSLEAY_VERSION_NUMBER with OPENSSL_VERSION_NUMBER,
for the sake of consistency. OPENSSL_VERSION_NUMBER has existed since time
immemorial.
Fix SSL test suite to work with OpenSSL 1.1.0. CA certificates must have
the "CA:true" basic constraint extension now, or OpenSSL will refuse them.
Regenerate the test certificates with that. The "openssl" binary, used to
generate the certificates, is also now more picky, and throws an error
if an X509 extension is specified in "req_extensions", but that section
is empty.
Backpatch to all supported branches, per popular demand. In back-branches,
we still support OpenSSL 0.9.7 and above. OpenSSL 0.9.6 should still work
too, but I didn't test it. In master, we only support 0.9.8 and above.

We were misapplying NameGetDatum() to plain C strings in some places.
This worked, because it was just a pointer cast anyway, but it's a type
cheat in some sense. Use CStringGetDatum instead, and modify the
NameGetDatum macro so it won't compile if applied to something that's
not a pointer to NameData. This should result in no changes to
generated code, but it is logically cleaner.

Teach the parser to reject misplaced set-returning functions during parse
analysis using p_expr_kind, in much the same way as we do for aggregates
and window functions (cf commit eaccfded9). While this isn't complete
(it misses nesting-based restrictions), it's much better than the previous
error reporting for such cases, and it allows elimination of assorted
ad-hoc expression_returns_set() error checks. We could add nesting checks
later if it seems important to catch all cases at parse time.
There is one case the parser will now throw error for although previous
versions allowed it, which is SRFs in the tlist of an UPDATE. That never
behaved sensibly (since it's ill-defined which generated row should be
used to perform the update) and it's hard to see why it should not be
treated as an error. It's a release-note-worthy change though.
Also, add a new Query field hasTargetSRFs reporting whether there are
any SRFs in the targetlist (including GROUP BY/ORDER BY expressions).
The parser can now set that basically for free during parse analysis,
and we can use it in a number of places to avoid expression_returns_set
searches. (There will be more such checks soon.) In some places, this
allows decontorting the logic since it's no longer expensive to check for
SRFs in the tlist --- so I made the checks parallel to the handling of
hasAggs/hasWindowFuncs wherever it seemed appropriate.
catversion bump because adding a Query field changes stored rules.

lockdefs.h was only split from lock.h relatively recently, and

The output of the function changes whenever previous (or, as in this
case, concurrent) tests leave a table in place. That causes unneeded
churn.
This should fix failures due to the tests added bfe16d1a5, like on

could also have been addressed by using temp tables, but that test has
annoyed me before.

We're considering changing the implementation of targetlist SRFs
considerably, and a lot of the current behaviour isn't tested in our
regression tests. Thus it seems useful to increase coverage to avoid
accidental behaviour changes.
It's quite possible that some of the plans here will require adjustments
to avoid falling afoul of ordering differences (e.g. hashed group
bys). The buildfarm will tell us.
