Peter Eisentraut f6f8d61a47 Fix uninstall target. 2008-02-26 13:48:57 +00:00
Peter Eisentraut 0e04ee41d0 Create two separate libpq.rc's: One that is built at build time, and one
that is shipped in the distribution, named libpq-dist.rc.  This way the
build system doesn't get upset when a distributed file is forcibly
overwritten by during a normal build.

Peter Eisentraut bdaf90b70f Reorganize some of the exports list generation code. It seems that this
has been reinvented about four different times throughout history (aix,
cygwin, win32, darwin/linux) and a lot of the concepts are actually shared,
which the code now shows better.

Peter Eisentraut d391bdac50 Need more dependencies to get the build order right when objfiles.txt
doesn't exist yet.
2008-02-26 08:23:31 +00:00
Peter Eisentraut 3690019da8 We don't need to rebuild objfiles.txt every time an object file changes.
So only rebuild when a makefile changes (which presumably defines the
file list somewhere), and only touch the file if an object changed. The
touch is necessary so the parent make knows something changed and
ultimately rebuilds postgres.

Tom Lane fd15dba543 Fix encode(...bytea..., 'escape') so that it converts all high-bit-set byte
values into \nnn octal escape sequences.  When the database encoding is
multibyte this is *necessary* to avoid generating invalidly encoded text.
Even in a single-byte encoding, the old behavior seems very hazardous ---
consider for example what happens if the text is transferred to another
database with a different encoding.  Decoding would then yield some other
bytea value than what was encoded, which is surely undesirable.  Per gripe
from Hernan Gonzalez.

Backpatch to 8.3, but not further.  This is a bit of a judgment call, but I
make it on these grounds: pre-8.3 we don't really have much encoding safety
anyway because of the convert() function family, and we would also have much
higher risk of breaking existing apps that may not be expecting this behavior.
8.3 is still new enough that we can probably get away with making this change
in the function's behavior.

Tom Lane bc93919be7 Reject year zero during datetime input, except when it's a 2-digit year
(then it means 2000 AD).  Formerly we silently interpreted this as 1 BC,
which at best is unwarranted familiarity with the implementation.
It's barely possible that some app somewhere expects the old behavior,
though, so we won't back-patch this into existing release branches.
2008-02-25 23:36:28 +00:00
Tom Lane 05506fc4af Fix datetime input to behave correctly for Feb 29 in years BC.
Formerly, DecodeDate attempted to verify the day-of-the-month exactly, but
it was under the misapprehension that it would know whether we were looking
at a BC year or not.  In reality this check can't be made until the calling
function (eg DecodeDateTime) has processed all the fields.  So, split the
BC adjustment and validity checks out into a new function ValidateDate that
is called only after processing all the fields.  In passing, this patch
makes DecodeTimeOnly work for BC inputs, which it never did before.

(The historical veracity of all this is nonexistent, of course, but if
we're going to say we support proleptic Gregorian calendar then we should
do it correctly.  In any case the unpatched code is broken because it could
emit dates that it would then reject on re-inputting.)

Per report from Bernd Helmle.  Back-patch as far as 8.0; in 7.x we were
not using our own calendar support and so this seems a bit too risky
to put into 7.4.

Peter Eisentraut 9956ddc191 Link postgres from all object files at once, to avoid the error-prone
SUBSYS.o step and allow for better optimization by the linker.

Instead of partial linking into SUBSYS.o, the list of object files is
assembled in objfiles.txt files that are expanded when the final
linking is done.

Because we are not yet sure how long command lines different platforms
can handle, the old way of linking is still available, by defining the
make variable PARTIAL_LINKING (e.g., make all PARTIAL_LINKING=1).  If
we determine that this is necessary for some platforms, then we will
document this in a more prominent place.

Tom Lane 9713c06319 Change the declaration of struct varlena so that the length word is
represented as "char ...[4]" not "int32".  Since the length word is never
supposed to be accessed via this struct member anyway, this won't break
any existing code that is following the rules.  The advantage is that C
compilers will no longer assume that a pointer to struct varlena is
word-aligned, which prevents incorrect optimizations in TOAST-pointer
access and perhaps other places.  gcc doesn't seem to do this (at least
not at -O2), but the problem is demonstrable on some other compilers.

I changed struct inet as well, but didn't bother to touch a lot of other
struct definitions in which it wouldn't make any difference because there
were other fields forcing int alignment anyway.  Hopefully none of those
struct definitions are used for accessing unaligned Datums.

Tom Lane 7454515e12 Fix mistakes in pg_ctl's code for "start -w" that tries to cope with
non-default settings for the postmaster's port number.  The code to parse
command line options and postgresql.conf entries wasn't quite right about
whitespace or quotes, and it was coded in a not-very-readable way too.
Per bug #3969 from Itagaki Takahiro, though this is more extensive than his
proposed patch (which fixed only the whitespace problem).
This code has been broken since it was put in in 8.0, so patch all the way
back.

Tom Lane 5ce6829b73 Put a CHECK_FOR_INTERRUPTS call into the loops that try to find a unique new
OID or new relfilenode.  If the existing OIDs are sufficiently densely
populated, this could take a long time (perhaps even be an infinite loop),
so it seems wise to allow the system to respond to a cancel interrupt here.
Per a gripe from Jacky Leng.

Backpatch as far as 8.1.  Older versions just fail on OID collision,
instead of looping.

Tom Lane cf59277ac9 Remove unnecessary opening of other relation in RI_FKey_keyequal_upd_pk
and RI_FKey_keyequal_upd_fk, as well as no-longer-needed calls of
ri_BuildQueryKeyFull.  Aside from saving a few cycles, this avoids needless
deadlock risks when an update is not changing the columns that participate
in an RI constraint.  Per a gripe from Alexey Nalbat.

Back-patch to 8.3.  Earlier releases did have a need to open the other
relation due to the way in which they retrieved information about the RI
constraint, so this problem unfortunately can't easily be improved pre-8.3.

Tom Lane cd00406774 Replace time_t with pg_time_t (same values, but always int64) in on-disk
data structures and backend internal APIs.  This solves problems we've seen
recently with inconsistent layout of pg_control between machines that have
32-bit time_t and those that have already migrated to 64-bit time_t.  Also,
we can get out from under the problem that Windows' Unix-API emulation is not
consistent about the width of time_t.

There are a few remaining places where local time_t variables are used to hold
the current or recent result of time(NULL).  I didn't bother changing these
since they do not affect any cross-module APIs and surely all platforms will
have 64-bit time_t before overflow becomes an actual risk.  time_t should
be avoided for anything visible to extension modules, however.

Tom Lane df1e965e12 Sync our regex code with upstream changes since last time we did this, which
was Tcl 8.4.8.  The main changes are to remove the never-fully-implemented
code for multi-character collating elements, and to const-ify some stuff a
bit more fully.  In combination with the recent security patch, this commit
brings us into line with Tcl 8.5.0.

Note that I didn't make any effort to duplicate a lot of cosmetic changes
that they made to bring their copy into line with their own style
guidelines, such as adding braces around single-line IF bodies.  Most of
those we either had done already (such as ANSI-fication of function headers)
or there is no point because pgindent would undo the change anyway.

Tom Lane cf9e156156 Stamp HEAD as 8.4devel. 2008-02-13 03:40:38 +00:00
Tom Lane 745e6edaae Fix SPI_cursor_open() and SPI_is_cursor_plan() to push the SPI stack before
doing anything interesting, such as calling RevalidateCachedPlan().  The
necessity of this is demonstrated by an example from Willem Buitendyk:
during a replan, the planner might try to evaluate SPI-using functions,
and so we'd better be in a clean SPI context.

A small downside of this fix is that these two functions will now fail
outright if called when not inside a SPI-using procedure (ie, a
SPI_connect/SPI_finish pair).  The documentation never promised or suggested
that that would work, though; and they are normally used in concert with
other functions, mainly SPI_prepare, that always have failed in such a case.
So the odds of breaking something seem pretty low.

In passing, make SPI_is_cursor_plan's error handling convention clearer,
and fix documentation's erroneous claim that SPI_cursor_open would
return NULL on error.

Before 8.3 these functions could not invoke replanning, so there is probably
no need for back-patching.

Tom Lane c931c07124 Repair VACUUM FULL bug introduced by HOT patch: the original way of
calculating a page's initial free space was fine, and should not have been
"improved" by letting PageGetHeapFreeSpace do it.  VACUUM FULL is going to
reclaim LP_DEAD line pointers later, so there is no need for a guard
against the page being too full of line pointers, and having one risks
rejecting pages that are perfectly good move destinations.

This also exposed a second bug, which is that the empty_end_pages logic
assumed that any page with no live tuples would get entered into the
fraged_pages list automatically (by virtue of having more free space than
the threshold in the do_frag calculation).  This assumption certainly
seems risky when a low fillfactor has been chosen, and even without
tunable fillfactor I think it could conceivably fail on a page with many
unused line pointers.  So fix the code to force do_frag true when notup
is true, and patch this part of the fix all the way back.

Per report from Tomas Szepe.

Tom Lane 9b43c245e3 Avoid misbehavior in foreign key checks when casting to a datatype for which
the parser supplies a default typmod that can result in data loss (ie,
truncation).  Currently that appears to be only CHARACTER and BIT.
We can avoid the problem by specifying the type's internal name instead
of using SQL-spec syntax.  Since the queries generated here are only used
internally, there's no need to worry about portability.  This problem is
new in 8.3; before we just let the parser do whatever it wanted to resolve
the operator, but 8.3 is trying to be sure that the semantics of FK checks
are consistent.  Per report from Harald Fuchs.

Tom Lane 1ab19a36a5 Some variants of ALTER OWNER tried to make the "object" field of the
statement be a list of bare C strings, rather than String nodes, which is
what they need to be for copyfuncs/equalfuncs to work.  Fortunately these
node types never go out to disk (if they did, we'd likely have noticed the
problem sooner), so we can just fix it without creating a need for initdb.
This bug has been there since 8.0, but 8.3 exposes it in a more common
code path (Parse messages) than prior releases did.  Per bug #3940 from
Vladimir Kokovic.

tablespace permissions failures when copying an index that is in the
database's default tablespace.  A side-effect of the change is that explicitly

this is not how it was done in pre-8.3 releases but is argued to be more
consistent.  Per bug #3921 from Andrew Gilligan.  (Note: I argued in the
subsequent discussion that maybe LIKE shouldn't copy index tablespaces
at all, but since no one indicated agreement with that idea, I've refrained
from doing it.)

explaining why it'd be a bad idea to use it for any other state cleanup.

Back-patch to 8.2.  Prior releases had the same issue, but only with respect
to the process title, which is likely to get reset almost immediately anyway
after the transaction aborts, so it seems not worth changing them.  In 8.2
and HEAD, the pg_stat_activity "waiting" flag could remain set incorrectly
for a long time.

Tom Lane 0688d84041 Add checks to TRUNCATE, CLUSTER, and REINDEX to prevent performing these
operations when the current transaction has any open references to the
target relation or index (implying it has an active query using the relation).
The need for this was previously recognized in connection with ALTER TABLE,
but anything that summarily eliminates tuples or moves them around would
confuse an active scan.

While this patch does not in itself fix bug #3883 (the deadlock would happen
before the new check fires), it will discourage people from attempting the
sequence of operations that creates a deadlock risk, so it's at least a
partial response to that problem.

In passing, add a previously-missing check to REINDEX to prevent trying to
reindex another backend's temp table.  This isn't a security problem since
only a superuser would get past the schema permission checks, but if we are
testing for this in other utility commands then surely REINDEX should too.

the patch for those features put its cleanup code into freePGconn() which is

comments in hopes of preventing similar mistakes in future.

Tom Lane fad2b99523 Arrange to ignore SIGPIPE during SSL_read() and SSL_shutdown(), as these
are known to write on the socket sometimes and thus we are vulnerable to
being killed by the signal if the server happens to go away unexpectedly.
Noticed while trying (futilely) to reproduce bug #3902.

This bug has been there all along, but since the situation is usually
only of interest to developers, I chose not to back-patch the changes.

Tom Lane 6322e84430 Change StatementCancelHandler() to check the DoingCommandRead flag to decide
whether to execute an immediate interrupt, rather than testing whether
LockWaitCancel() cancelled a lock wait.  The old way misclassified the case
where we were blocked in ProcWaitForSignal(), and arguably would misclassify
any other future additions of new ImmediateInterruptOK states too.  This
allows reverting the old kluge that gave LockWaitCancel() a return value,
since no callers care anymore.  Improve comments in the various
implementations of PGSemaphoreLock() to explain that on some platforms, the
assumption that semop() exits after a signal is wrong, and so we must ensure
that the signal handler itself throws elog if we want cancel or die interrupts
to be effective.  Per testing related to bug #3883, though this patch doesn't
solve those problems fully.

Perhaps this change should be back-patched, but since pre-8.3 branches aren't
really relying on autovacuum to respond to SIGINT, it doesn't seem critical
for them.

ri_FetchConstraintInfo, to avoid a query-duration memory leak when that
routine is called by RI_FKey_keyequal_upd_fk (which isn't executed in a
short-lived context).  This problem was latent when the routine was added
in February, but it didn't become serious until the varvarlena patch made
it quite likely that the fields being examined would be "toasted" (ie, have
short headers).  Per report from Stephen Denne.

Tom Lane 70066eb1a1 Insert into getCopyDataMessage() the same logic that already existed in the
main code path for enlarging libpq's input buffer in one swoop when needing to
read a long data message.  Without this, the code will double the buffer size,
read more data, notice it still hasn't got the whole message, and repeat till
it finally has a large enough buffer.  Which wastes a lot of data-moving
effort and also memory (since malloc probably can't do anything very useful
with the freed-up smaller buffers).  Not sure why this wasn't there already;
certainly the COPY data path is a place where we're quite likely to see long
data messages.  I'm not backpatching though, since this is just a marginal
performance issue rather than a real bug.

Tom Lane a44174cf90 Fix subselect.c to avoid assuming that a SubLink's testexpr references each

in the original parser output, it might not be so after rewriting and
constant-folding, as illustrated by bug #3882 from Jan Mate.  Instead
scan the subquery's target list to obtain needed per-column information;
this is duplicative of what the parser did, but only a couple dozen lines
need be copied, and we can clean up a couple of notational uglinesses.
Bug was introduced in 8.2 as part of revision of SubLink representation.

Tom Lane ac12412ede Revise memory management for libxml calls. Instead of keeping libxml's data
in whichever context happens to be current during a call of an xml.c function,
use a dedicated context that will not go away until we explicitly delete it
(which we do at transaction end or subtransaction abort).  This makes recovery
after an error much simpler --- we don't have to individually delete the data
structures created by libxml.  Also, we need to initialize and cleanup libxml
only once per transaction (if there's no error) instead of once per function
call, so it should be a bit faster.  We'll need to keep an eye out for
intra-transaction memory leaks, though.  Alvaro and Tom.

Tom Lane 208d0a2321 Fix logical errors in constraint exclusion: we cannot assume that a CHECK
constraint yields TRUE for every row of its table, only that it does not
yield FALSE (a NULL result isn't disallowed).  This breaks a couple of
implications that would be true in two-valued logic.  I had put in one such
mistake in an 8.2.5 patch: foo IS NULL doesn't refute a strict operator
on foo.  But there was another in the original 8.2 release: NOT foo doesn't
refute an expression whose truth would imply the truth of foo.
Per report from Rajesh Kumar Mallah.

To preserve the ability to do constraint exclusion with one partition
holding NULL values, extend relation_excluded_by_constraints() to check
for attnotnull flags, and add col IS NOT NULL expressions to the set of
constraints we hope to refute.

Tom Lane df62977d00 Fix an old error in clause_selectivity: the default selectivity estimate
for unhandled clause types ought to be 0.5, not 1.0.  I fear I introduced
this silliness due to misreading the intent of the very-poorly-structured
code that was there when we inherited the file from Berkeley.  The lack
of sanity in this behavior was exposed by an example from Sim Zacks.
(Arguably this is a bug fix and should be back-patched, but I'm a bit
hesitant to introduce a possible planner behavior change in the back
branches; it might detune queries that worked acceptably in the past.)

While at it, make estimation for DistinctExpr do something marginally
realistic, rather than just defaulting.

Tom Lane 59fc64acee Fix a conceptual error in my patch of 2007-10-26 that avoided considering
clauseless joins of relations that have unexploited join clauses.  Rather
than looking at every other base relation in the query, the correct thing is
to examine the other relations in the "initial_rels" list of the current
make_rel_from_joinlist() invocation, because those are what we actually have
the ability to join against.  This might be a subset of the whole query in
cases where join_collapse_limit or from_collapse_limit or full joins have
prevented merging the whole query into a single join problem.  This is a bit
untidy because we have to pass those rels down through a new PlannerInfo
field, but it's necessary.  Per bug #3865 from Oleg Kharin.
2008-01-11 04:02:18 +00:00
Tom Lane e6a442c71b Restructure the shutdown procedure for the archiver process to allow it to
finish archiving everything (when there's no error), and to eliminate various
hazards as best we can.  This fixes a previous 8.3 patch that caused the
postmaster to kill and then restart the archiver during shutdown (!?).

The new behavior is that the archiver is allowed to run unmolested until
the bgwriter has exited; then it is sent SIGUSR2 to tell it to do a final
archiving cycle and quit.  We only SIGQUIT the archiver if we want a panic
stop; this is important since SIGQUIT will also be sent to any active
archive_command.  The postmaster also now doesn't SIGQUIT the stats collector
until the bgwriter is done, since the bgwriter can send stats messages in 8.3.
The postmaster will not exit until both the archiver and stats collector are
gone; this provides some defense (not too bulletproof) against conflicting
archiver or stats collector processes being started by a new postmaster
instance.  We continue the prior practice that the archiver will check
for postmaster death immediately before issuing any archive_command; that
gives some additional protection against conflicting archivers.

Also, modify the archiver process to notice SIGTERM and refuse to issue any
more archive commands if it gets it.  The postmaster doesn't ever send it
SIGTERM; we assume that any such signal came from init and is a notice of
impending whole-system shutdown.  In this situation it seems imprudent to try
to start new archive commands --- if they aren't extremely quick they're
likely to get SIGKILL'd by init.

All per discussion.

Tom Lane 6a6522529f Fix some planner issues found while investigating Kevin Grittner's report
of poorer planning in 8.3 than 8.2:

1. After pushing a constant across an outer join --- ie, given
"a LEFT JOIN b ON (a.x = b.y) WHERE a.x = 42", we can deduce that b.y is
sort of equal to 42, in the sense that we needn't fetch any b rows where
it isn't 42 --- loop to see if any additional deductions can be made.
Previous releases did that by recursing, but I had mistakenly thought that
this was no longer necessary given the EquivalenceClass machinery.

2. Allow pushing constants across outer join conditions even if the
condition is outerjoin_delayed due to a lower outer join.  This is safe
as long as the condition is strict and we re-test it at the upper join.

3. Keep the outer-join clause even if we successfully push a constant
across it.  This is *necessary* in the outerjoin_delayed case, but
even in the simple case, it seems better to do this to ensure that the
join search order heuristics will consider the join as reasonable to
make.  Mark such a clause as having selectivity 1.0, though, since it's
not going to eliminate very many rows after application of the constant
condition.

4. Tweak have_relevant_eclass_joinclause to report that two relations
are joinable when they have vars that are equated to the same constant.
We won't actually generate any joinclause from such an EquivalenceClass,
but again it seems that in such a case it's a good idea to consider
the join as worth costing out.

5. Fix a bug in select_mergejoin_clauses that was exposed by these
changes: we have to reject candidate mergejoin clauses if either side was
equated to a constant, because we can't construct a canonical pathkey list
for such a clause.  This is an implementation restriction that might be
worth fixing someday, but it doesn't seem critical to get it done for 8.3.

Tom Lane 5935890775 A long time ago, Peter pointed out that ruleutils.c didn't dump simple
constant ORDER/GROUP BY entries properly:
http://archives.postgresql.org/pgsql-hackers/2001-04/msg00457.php
The original solution to that was in fact no good, as demonstrated by
today's report from Martin Pitt:
http://archives.postgresql.org/pgsql-bugs/2008-01/msg00027.php
We can't use the column-number-reference format for a constant that is
a resjunk targetlist entry, a case that was unfortunately not thought of
in the original discussion.  What we can do instead (which did not work
at the time, but does work in 7.3 and up) is to emit the constant with
explicit ::typename decoration, even if it otherwise wouldn't need it.
This is sufficient to keep the parser from thinking it's a column number
reference, and indeed is probably what the user must have done to get
such a thing into the querytree in the first place.

Tom Lane eedb068c0a Make standard maintenance operations (including VACUUM, ANALYZE, REINDEX,
and CLUSTER) execute as the table owner rather than the calling user, using
the same privilege-switching mechanism already used for SECURITY DEFINER
functions.  The purpose of this change is to ensure that user-defined
functions used in index definitions cannot acquire the privileges of a
superuser account that is performing routine maintenance.  While a function
used in an index is supposed to be IMMUTABLE and thus not able to do anything
very interesting, there are several easy ways around that restriction; and
even if we could plug them all, there would remain a risk of reading sensitive
information and broadcasting it through a covert channel such as CPU usage.

To prevent bypassing this security measure, execution of SET SESSION
AUTHORIZATION and SET ROLE is now forbidden within a SECURITY DEFINER context.

Tom Lane 98f27aaef3 Fix assorted security-grade bugs in the regex engine. All of these problems
are shared with Tcl, since it's their code to begin with, and the patches
have been copied from Tcl 8.5.0.  Problems:

CVE-2007-4769: Inadequate check on the range of backref numbers allows
crash due to out-of-bounds read.
CVE-2007-4772: Infinite loop in regex optimizer for pattern '($|^)*'.
CVE-2007-6067: Very slow optimizer cleanup for regex with a large NFA
representation, as well as crash if we encounter an out-of-memory condition
during NFA construction.

Part of the response to CVE-2007-6067 is to put a limit on the number of
states in the NFA representation of a regex.  This seems needed even though
the within-the-code problems have been corrected, since otherwise the code
could try to use very large amounts of memory for a suitably-crafted regex,
leading to potential DOS by driving the system into swap, activating a kernel
OOM killer, etc.

Although there are certainly plenty of ways to drive the system into effective
DOS with poorly-written SQL queries, these problems seem worth treating as
security issues because many applications might accept regex search patterns
from untrustworthy sources.

Tom Lane 20e862155f Forbid ALTER TABLE and CLUSTER when there are pending AFTER-trigger events
in the current backend for the target table.  These operations move tuples
around and would thus invalidate the TIDs stored in the trigger event records.
(We need not worry about events in other backends, since acquiring exclusive
lock should be enough to ensure there aren't any.)  It might be sufficient
to forbid only the table-rewriting variants of ALTER TABLE, but in the absence
of any compelling use-case, let's just be safe and simple.  Per follow-on
investigation of bug #3847, though this is not actually the same problem

Tom Lane baecbb9165 Fix plpython's overoptimistic caching of information about the rowtype of
a trigger's target table.  The rowtype could change from one call to the
next, so cope in such cases, while avoiding doing repetitive catalog lookups.
Per bug #3847 from Mark Reid.

Backpatch to 8.2.x.  Likely this fix should go further back, but I can't test
it because I no longer have a machine with a pre-2.5 Python installation.
(Maybe we should rethink that idea about not supporting Python 2.5 in the
older branches.)

Tom Lane ac1ae9f2fa Improve a number of elog messages for not-supposed-to-happen cases in btrees,
since these seem to happen after all in corrupted indexes.  Make sure we
supply the index name in all cases, and provide relevant block numbers where
available.  Also consistently identify the index name as such.

Back-patch to 8.2, in hopes that this might help Mason Hale figure out his
problem.

Tom Lane 5233dc15cf Improve consistency of error reporting in GUC assign_hook routines. Some
were reporting ERROR for interactive assignments and LOG for other cases,
some were saying nothing for non-interactive cases, and a few did yet other
things.  Make them use a new function GUC_complaint_elevel() to establish
a reasonably uniform policy about how to report.  There are still a few
edge cases such as assign_search_path(), but it's much better than before.
Per gripe from Devrim Gunduz and subsequent discussion.

As noted by Alvaro, it'd be better to fold these custom messages into the
standard "invalid parameter value" complaint from guc.c, perhaps as the DETAIL
field.  However that will require more redesign than seems prudent for 8.3.
This is a relatively safe, low-impact change that we can afford to risk now.
