Tom Lane 166b5c1def Another round of planner/optimizer work. This is just restructuring and
code cleanup; no major improvements yet.  However, EXPLAIN does produce
more intuitive outputs for nested loops with indexscans now...

Thomas G. Lockhart 3ec826f99a Repair two recently reported problems:
1) datetime_pl_span() added the seconds field before adding the months
 field.  This lead to erroneous results for e.g.
   select datetime '1999-11-30' + timespan '1 mon - 1 sec';
 Reverse the order of operations to add months first.
2) tm2timespan() did all intermediate math as integer, converting to double
 at the very end. This resulted in hidden overflows when given very large
 integer days, hours, etc. For example,
   select '74565 days'::timespan;
 produced the wrong result. Change code to ensure that doubles are used
 for intermediate calculations.

Tom Lane 2784a5aedf Clean up datatypes and comments for op_class() routine. 1999-12-31 03:18:43 +00:00
Tom Lane 8a40400d40 elog() was set up to call abort() if it saw an ERROR or FATAL exit
during InitProcessingMode and the CurrentTransactionState was neither
TRANS_DEFAULT nor TRANS_DISABLED.  Unfortunately, after someone's recent
change to start the transaction manager earlier in startup than it used
to be started, that caused an abort() and consequent database system
reset on quite harmless errors (such as rejecting an invalid user name!).
As far as I can see, the test on CurrentTransactionState was completely
useless anyway, so I've removed it.

Tom Lane 9c95f8c9b2 Repair bugs discussed in pghackers thread of 15 May 1999: creation of a
relcache entry no longer leaks a small amount of memory.  index_endscan
now releases all the memory acquired by index_beginscan, so callers of it
should NOT pfree the scan descriptor anymore.

Tom Lane 350cb386af Clean up handling of explicit NULL constants. Cases like
SELECT null::text;
	SELECT int4fac(null);
work as expected now.  In some cases a NULL must be surrounded by
parentheses:
	SELECT 2 + null;                 fails
	SELECT 2 + (null);               OK
This is a grammatical ambiguity that seems difficult to avoid.  Other
than that, NULLs seem to behave about like you'd expect.  The internal
implementation is that NULL constants are typed as UNKNOWN (like
untyped string constants) until the parser can deduce the right type.

Bruce Momjian bb50fb517f This patch will avoid SIGFPE on some geo functions , if PostgreSQL is compiled
with DEC C.

DEC C doesn't handle double values greater than DBL_MAX, but some
PostgreSQL geo functions assign greater than DBL_MAX values to some vars
in some special cases - that couses SIGFPE. I dunno if that is the only place
to fix to work well with DEC C.

Tom Lane f74b94db09 Finally found a platform which has finite() but nonetheless sets errno
rather than returning a NaN for bogus input to pow().  Namely, HPUX 10.20.
I think this is sufficient evidence for what I thought all along, which
is that the float.c code *must* look at errno whether finite() exists or
not.

Bruce Momjian d65a27f950 Hi,
I was able to crash postgres 6.5.3 when I did an 'alter user' command.
After I started a debugger I found the problem in the timezone handling
of
datetime (my Linux box lost its timezone information, that's how the
problem occurred).

Only 7 bytes are reserved for the timezone, without checking for
boundaries.

Attached is a patch that fixes this problem and emits a NOTICE if a
timezone is encountered that is longer than MAXTZLEN bytes, like this:

Tom Lane 76ccf73f2b Repair problem exposed by Jan's new parallel-regression-test scaffold:
inval.c thought it could safely use the catcache to look up the OIDs of

during catcache loading, if a shared-inval message arrives.  Rip out the
lookup logic and instead use the known OIDs from pg_class.h.

Tom Lane e1492cc34c Modify elog() logic so that it won't try to longjmp(Warn_restart) before
Warn_restart has been set by the backend main loop.  This means that
elog(ERROR) or elog(FATAL) in the postmaster or during backend startup
now have well-defined behavior: proc_exit() rather than coredump.
In the case of elog() inside the postmaster, I think that proc_exit()
is probably not enough --- don't we want our child backends to be
forced to quit too?  But I don't understand Vadim's recent changes in
this area, so I'll leave it to him to look over and tweak if needed.

Tom Lane f68e11f373 Implement subselects in target lists. Also, relax requirement that
subselects can only appear on the righthand side of a binary operator.
That's still true for quantified predicates like x = ANY (SELECT ...),
but a subselect that delivers a single result can now appear anywhere
in an expression.  This is implemented by changing EXPR_SUBLINK sublinks
to represent just the (SELECT ...) expression, without any 'left hand
side' or combining operator --- so they're now more like EXISTS_SUBLINK.
To handle the case of '(x, y, z) = (SELECT ...)', I added a new sublink
type MULTIEXPR_SUBLINK, which acts just like EXPR_SUBLINK used to.
But the grammar will only generate one for a multiple-left-hand-side
row expression.
1999-11-15 02:00:15 +00:00
Bruce Momjian 86ef36c907 New NameStr macro to convert Name to Str. No need for var.data anymore.

Hiroshi Inoue 2e2189a568 Make it possible to execute crashed CREATE/DROP commands again.
Now indexes of pg_class and pg_type are unique indexes
and guarantee the uniqueness of correponding attributes.
heap_create() was changed to take another boolean parameter
which allows to postpone the creation of disk file.
The name of rd_nonameunlinked was changed to rd_unlinked.
It is used generally(not only for noname relations) now.

Tom Lane cf627ab41a Further performance improvements in sorting: reduce number of comparisons
during initial run formation by keeping both current run and next-run
tuples in the same heap (yup, Knuth is smarter than I am).  And, during
merge passes, make use of available sort memory to load multiple tuples
from any one input 'tape' at a time, thereby improving locality of
access to the temp file.

Tom Lane 51f62d505e Standardize on MAXPGPATH as the size of a file pathname buffer,
eliminating some wildly inconsistent coding in various parts of the
system.  I set MAXPGPATH = 1024 in config.h.in.  If anyone is really
convinced that there ought to be a configure-time test to set the
value, go right ahead ... but I think it's a waste of time.

Tom Lane 26c48b5e8c Final stage of psort reconstruction work: replace psort.c with
a generalized module 'tuplesort.c' that can sort either HeapTuples or
IndexTuples, and is not tied to execution of a Sort node.  Clean up
memory leakages in sorting, and replace nbtsort.c's private implementation
of mergesorting with calls to tuplesort.c.
1999-10-17 22:15:09 +00:00
Tom Lane 957146dcec Second phase of psort reconstruction project: add bookkeeping logic to
recycle storage within sort temp file on a block-by-block basis.  This
reduces peak disk usage to essentially just the volume of data being
sorted, whereas it had been about 4x the data volume before.
1999-10-16 19:49:28 +00:00
Tom Lane db3c4c3a2d Split 'BufFile' routines out of fd.c into a new module, buffile.c. Extend
BufFile so that it handles multi-segment temporary files transparently.
This allows sorts and hashes to work with data exceeding 2Gig (or whatever
the local limit on file size is).  Change psort.c to use relative seeks
instead of absolute seeks for backwards scanning, so that it won't fail
when the data volume exceeds 2Gig.

Tom Lane 3e21ecbbe6 Make the rule deparser a little less quote-happy, so that
display of default expressions isn't quite so ugly.
1999-10-04 04:37:23 +00:00
Tom Lane eabc714a91 Reimplement parsing and storage of default expressions and constraint
expressions in CREATE TABLE.  There is no longer an emasculated expression
syntax for these things; it's full a_expr for constraints, and b_expr
for defaults (unfortunately the fact that NOT NULL is a part of the
column constraint syntax causes a shift/reduce conflict if you try a_expr.
Oh well --- at least parenthesized boolean expressions work now).  Also,
stored expression for a column default is not pre-coerced to the column
type; we rely on transformInsertStatement to do that when the default is
actually used.  This means "f1 datetime default 'now'" behaves the way
people usually expect it to.
BTW, all the support code is now there to implement ALTER TABLE ADD
CONSTRAINT and ALTER TABLE ADD COLUMN with a default value.  I didn't
actually teach ALTER TABLE to call it, but it wouldn't be much work.
1999-10-03 23:55:40 +00:00
Tom Lane 6eb8d255d2 Allow CREATE FUNCTION's WITH clause to be used for all language types,
not just C, so that ISCACHABLE attribute can be specified for user-defined

generated by gram.y anymore, even though define.c thought that was what
it was getting.  Clean up minor bug in dfmgr.c (premature heap_close).
1999-10-02 21:33:33 +00:00
Tom Lane 1f122a7c4c Replace float.c's #ifdef finite check with a proper autoconf check, so it

Tom Lane cd243d27ce Revise rule-printing routines to use expandable StringInfo buffers, so that
they have no hardwired limit on the length of a rule's text.  Fix a couple
of minor bugs in passing --- deparsed UPDATE queries didn't have quotes
around relation name, and quotes and backslashes in constant values weren't
backslash-quoted.

1999-09-28 11:27:13 +00:00
Bruce Momjian 9394d62c73 I have been working with user defined types and user defined c
functions.  One problem that I have encountered with the function
manager is that it does not allow the user to define type conversion
functions that convert between user types. For instance if mytype1,
mytype2, and mytype3 are three Postgresql user types, and if I wish to
define Postgresql conversion functions like

I run into problems, because the Postgresql dynamic loader would look
for a single link symbol, mytype3, for both pieces of object code.  If
I just change the name of one of the Postgresql functions (to make the
symbols distinct), the automatic type conversion that Postgresql uses,
for example, when matching operators to arguments no longer finds the
type conversion function.

The solution that I propose, and have implemented in the attatched
patch extends the CREATE FUNCTION syntax as follows. In the first case
above I use the link symbol mytype2_to_mytype3 for the link object
that implements the first conversion function, and define the
Postgresql operator with the following syntax

The patch includes changes to the parser to include the altered
syntax, changes to the ProcedureStmt node in nodes/parsenodes.h,
changes to commands/define.c to handle the extra information in the AS
clause, and changes to utils/fmgr/dfmgr.c that alter the way that the
dynamic loader figures out what link symbol to use.  I store the
string for the link symbol in the prosrc text attribute of the pg_proc
table which is currently unused in rows that reference dynamically
loaded
functions.

Tom Lane be09bc9ff2 Modify nodeAgg.c so that no rows are returned for a GROUP BY
with no input rows, per pghackers discussions around 7/22/99.  Clean up
a bunch of ugly coding while at it; remove redundant re-lookup of
aggregate info at start of each new GROUP.  Arrange to pfree intermediate
values when they are pass-by-ref types, so that aggregates on pass-by-ref
types no longer eat memory.  This takes care of a couple of TODO items...

Tom Lane e812458b27 Several changes here, not very related but touching some of the same files.
* Buffer refcount cleanup (per my "progress report" to pghackers, 9/22).
* Add links to backend PROC structs to sinval's array of per-backend info,
and use these links for routines that need to check the state of all
backends (rather than the slow, complicated search of the ShmemIndex
hashtable that was used before).  Add databaseOID to PROC structs.
* Use this to implement an interlock that prevents DESTROY DATABASE of
a database containing running backends.  (It's a little tricky to prevent
a concurrently-starting backend from getting in there, since the new
backend is not able to lock anything at the time it tries to look up
its database in pg_database.  My solution is to recheck that the DB is
OK at the end of InitPostgres.  It may not be a 100% solution, but it's
a lot better than no interlock at all...)
* In ALTER TABLE RENAME, flush buffers for the relation before doing the
rename of the physical files, to ensure we don't get failures later from
mdblindwrt().
* Update TRUNCATE patch so that it actually compiles against current
sources :-(.
You should do "make clean all" after pulling these changes.

Bruce Momjian dabc3f31b5 Fix for netmask('x.x.x.x/0') is 255.255.255.255 instead of 0.0.0.0

Bruce Momjian ad604ac372 values.h patch from Alex Howansky 1999-09-21 20:58:25 +00:00
Tom Lane bd272cace6 Mega-commit to make heap_open/heap_openr/heap_close take an
additional argument specifying the kind of lock to acquire/release (or
'NoLock' to do no lock processing).  Ensure that all relations are locked
with some appropriate lock level before being examined --- this ensures
that relevant shared-inval messages have been processed and should prevent
problems caused by concurrent VACUUM.  Fix several bugs having to do with
mismatched increment/decrement of relation ref count and mismatched
heap_open/close (which amounts to the same thing).  A bogus ref count on
a relation doesn't matter much *unless* a SI Inval message happens to
arrive at the wrong time, which is probably why we got away with this
sloppiness for so long.  Repair missing grab of AccessExclusiveLock in
DROP TABLE, ALTER/RENAME TABLE, etc, as noted by Hiroshi.
Recommend 'make clean all' after pulling this update; I modified the
Relation struct layout slightly.
Will post further discussion to pghackers list shortly.

Tom Lane 4644fc8071 Eliminate query length limitation imposed by pg_client_to_server
and pg_server_to_client.  Eliminate copy.c's restriction on the length
of a single attribute.
1999-09-11 22:28:11 +00:00
Tom Lane b399805e22 Eliminate elog()'s hardwired limit on length of an error message.
This change seems necessary in conjunction with long queries, and it
cleans up some bogosity in connection with long EXPLAIN texts anyway.
Note that current libpq will accept any length error message (at least
until it runs out of memory); prior versions have a limit of 8K, but
will cleanly discard excess error text, so there shouldn't be any
big compatibility problems with old clients.
1999-09-11 19:06:42 +00:00
Tom Lane 5bc0d31ae8 Repair incorrect cleanup of heap memory allocation during
transaction abort --- before it only worked if there was exactly one level
of allocation context stacked in the blank portal.  Now it does the right
thing for any depth, including zero...

Tom Lane 51db6455ea Repair error noticed by Roberto Cornacchia: selectivity code
was rejecting negative attnums as bogus, which of course they are not.
Add code to get_attdisbursion to produce a useful value for OID attribute,
since VACUUM does not store stats for system attributes.
Also, repair bug that's been in eqjoinsel for a long time: it was taking
the max of the two columns' disbursions, whereas it should use the min.

1999-09-07 19:09:46 +00:00
Tom Lane cc8b67a5c3 Fix relcache.c so that local relations (those created during
current transaction) are not flushed by shared-cache-inval reset message.
SI reset actually works now, for probably the first time in a long time.
I was able to run initdb and regression tests with a 16-element SI message
array, with a lot of NOTICE: cache state reset messages but no crashes.

Tom Lane cb36c0f682 In RelationNameGetRelation(), replace temp table name by
real name before doing lookup.  We only want to index temp tables by their
real names in the relcache, to ensure there's not more than one relcache
entry for them.
1999-09-04 21:47:23 +00:00
Tom Lane 15dd167854 Avoid transaction overhead when there are no temp tables
to be deleted.

Bruce Momjian fb7548f4db Invalidate temp entries for aborted transactions. 1999-09-04 19:55:50 +00:00
Tom Lane b4a607c9e0 Modify RelationFlushRelation so that if the relcache entry
has positive refcount, it is rebuilt from pg_class data.  This ensures
that relcache entries will track changes made by other backends.  Formerly,
a shared inval report would just be ignored if it happened to arrive while
the relcache entry was in use.  Also, fix relcache to reset ref counts
to zero during transaction abort.  Finally, change LockRelation() so that
it checks for shared inval reports after obtaining the lock.  In this way,
once any kind of lock has been obtained on a rel, we can trust the relcache
entry to be up-to-date.
1999-09-04 18:42:15 +00:00
Tom Lane 51f62ea45c Rule deparser didn't handle unary operators correctly. 1999-09-02 03:04:04 +00:00
Tom Lane 68c323483c Repair a bunch of problems in md.c. This builds on Hiroshi's
insight that RelationFlushRelation ought to invoke smgrclose, and that the
way to make that work is to ensure that mdclose doesn't fail if the relation
is already closed (or unlinked, if we are looking at a DROP TABLE).  While
I was testing that, I was able to identify several problems that we had
with multiple-segment relations.  The system is now able to do initdb and
pass the regression tests with a very small segment size (I had it set to
64Kb per segment for testing).  I don't believe that ever worked before.
File descriptor leaks seem to be gone too.
I have partially addressed the concerns we had about mdtruncate(), too.
On a Win32 or NFS filesystem it is not possible to unlink a file that
another backend is holding open, so what md.c now does is to truncate
unwanted files to zero length before trying to unlink them.  The other
backends will be forced to close their open files by relation cache
invalidation --- but I think it would take considerable work to make
that happen before vacuum truncates the relation rather than after.
Leaving zero-length files lying around seems a usable compromise.
1999-09-02 02:57:50 +00:00
Tom Lane 958600156c Fix several problems in rule deparsing: didn't handle array
references or CASE expressions, didn't parenthesize complex expressions
properly.  Also, always output variable references as fully qualified
names to eliminate ambiguity bug recently reported.  (This could be
smarter, but reliability comes first.)
1999-08-28 03:59:05 +00:00
Tom Lane 42af56e1ea Revise implementation of SubLinks so that there is a consistent,
documented intepretation of the lefthand and oper fields.  Fix a number of
obscure problems while at it --- for example, the old code failed if the parser
decided to insert a type-coercion function just below the operator of a
SubLink.
CAUTION: this will break stored rules that contain subplans.  You may
need to initdb.
1999-08-25 23:21:43 +00:00
Tom Lane 2b67dc5387 Alter AllocSet routines so that requests larger than
ALLOC_BIGCHUNK_LIMIT are always allocated as separate malloc() blocks,
and are free()d immediately upon pfree().  Also, if such a chunk is enlarged
with repalloc(), translate the operation into a realloc() so as to
minimize memory usage.  Of course, these large chunks still get freed
automatically if the alloc set is reset.
I have set ALLOC_BIGCHUNK_LIMIT at 64K for now, but perhaps another
size would be better?
1999-08-24 20:11:19 +00:00
Tom Lane db436adf76 Major revision of sort-node handling: push knowledge of query
sort order down into planner, instead of handling it only at the very top
level of the planner.  This fixes many things.  An explicit sort is now
avoided if there is a cheaper alternative (typically an indexscan) not
only for ORDER BY, but also for the internal sort of GROUP BY.  It works
even when there is no other reason (such as a WHERE condition) to consider
the indexscan.  It works for indexes on functions.  It works for indexes
on functions, backwards.  It's just so cool...

CAUTION: I have changed the representation of SortClause nodes, therefore
THIS UPDATE BREAKS STORED RULES.  You will need to initdb.
1999-08-21 03:49:17 +00:00

Tom Lane 8624ff7612 Further selectivity-estimation work. Speed up eqsel()
(it should just call the given operator, not look up an = operator).
Fix intltsel() so that all numeric data types are converted to double
before trying to estimate where the given comparison value is in the
known range of column values.  intltsel() still needs work, or replacement,
for non-numeric data types ... but for nonintegral numeric types it
should now be delivering reasonable estimates.
1999-08-02 02:05:41 +00:00
Tom Lane 44878506d8 First step in fixing selectivity-estimation code. eqsel and
neqsel now behave as per my suggestions in pghackers a few days ago.
selectivity for < > <= >= should work OK for integral types as well, but
still need work for nonintegral types.  Since these routines have never
actually executed before :-(, this may result in some significant changes
in the optimizer's choices of execution plans.  Let me know if you see
any serious misbehavior.
CAUTION: THESE CHANGES REQUIRE INITDB.  pg_statistic table has changed.

Bruce Momjian 5035d7b985 pg_atoi() does range check on int4 data only if
"HAS_LONG_LONG" is defined based on the assumption that
strtol() would return ERANGE if a platform does not support
64-bit integers. In current PostgreSQL 6.5 (and 6.4.2)
distribution, "HAS_LONG_LONG" is defined only if platform
is "alpha". (See include/port/alpha.h) I think the int4
range check should apply to linux_alpha as well. (I have
not tested yet but I guess this might be applicable to
newer Linux/i386 distributions which includes new GCC which
implements long int as 64-bit int.)

Bruce Momjian 0c3281ce7c Reversed out Massimo patch. 1999-06-12 14:07:33 +00:00
Bruce Momjian 603e153bb8 I don't like last minute patches before the final freeze, but I believe that
this one could be useful for people experiencing out-of-memory crashes while
executing queries which retrieve or use a very large number of tuples.

The problem happens when storage is allocated for functions results used in
a large query, for example:

  select upper(name) from big_table;
  select big_table.array[1] from big_table;
  select count(upper(name)) from big_table;

This patch is a dirty hack that fixes the out-of-memory problem for the most
common cases, like the above ones. It is not the final solution for the
problem but it can work for some people, so I'm posting it.

The patch should be safe because all changes are under #ifdef. Furthermore
the feature can be enabled or disabled at runtime by the `free_tuple_memory'
options in the pg_options file. The option is disabled by default and must
be explicitly enabled at runtime to have any effect.

To enable the patch add the follwing line to Makefile.custom:

CUSTOM_COPT += -DFREE_TUPLE_MEMORY

To enable the option at runtime add the following line to pg_option:

free_tuple_memory=1

 <<refint1.patch>>
After that you can remove the following from TODO:
Remove ERROR:  check_primary_key: even number of arguments should be
specified
Trigger regression test fails

1999-05-03 23:48:26 +00:00
Bruce Momjian 210055ad61 here are some patches for 6.5.0 which I already submitted but have never
been applied. The patches are in the .tar.gz attachment at the end:

varchar-array.patch     this patch adds support for arrays of bpchar() and
                        varchar(), which where always missing from postgres.

                        These datatypes can be used to replace the _char4,
                        _char8, etc., which were dropped some time ago.

block-size.patch        this patch fixes many errors in the parser and other
                        program which happen with very large query statements
                        (> 8K) when using a page size larger than 8192.

                        This patch is needed if you want to submit queries
                        larger than 8K. Postgres supports tuples up to 32K
                        but you can't insert them because you can't submit
                        queries larger than 8K. My patch fixes this problem.

                        The patch also replaces all the occurrences of `8192'
                        and `1<<13' in the sources with the proper constants
                        defined in include files. You should now never find
                        8192 hardwired in C code, just to make code clearer.

not the process itself. As a result, parent sh gets core dumped in the
Wisconsin benchmark test.

Tom Lane c537d4295a Modify fmgr so that internal name (compiler name) of a built-in
function is found in prosrc field of pg_proc, not proname.  This allows
multiple aliases of a built-in to all be implemented as direct builtins,
without needing a level of indirection through an SQL function.  Replace
existing SQL alias functions with builtin entries accordingly.
Save a few K by not storing string names of builtin functions in fmgr's
internal table (if you really want 'em, get 'em from pg_proc...).
Update opr_sanity with a few more cross-checks.

Bruce Momjian c10e6bcbed Attempting to insert a value of 'now' into a datetime type
results in a bogus datetime value under AlphaLinux.  (Note that
the link to submit a port-specific bug on your website is broken)

-Test Case:
----------
testdb=> create table dttest (dt datetime);
testdb=> insert into dttest values ('now');

--------------------------------------------------------------------------


Solution:
---------
The basic problem is the typedefs of AbsoluteTime and RelativeTime,
which are both 'int32'.  These types appear to be used synonymously
with the 'time_t' type, which on AlphaLinux is typedef'd as a 'long
int', which is 64-bits (not 32).  The solution included here fixes
the datetime type (it now passes the regression test), but does not
pass the absolute and relative time regression tests.  Presumably, a
more thorough investigation of how these types are used is warranted.
The included patch is from the v6.3.2 source, but can be applied to
the v6.4.2 source.  Please note that there is also a RedHat-specific
patch distributed with the PostgreSQL source package from RedHat
that was applied first.

Bruce Momjian aba8c12f67 We have tested the patches on three platforms:
NetBSD/macppc
LinuxPPC
FreeBSD 2.2.6-RELEASE

All of them seem happy with the regression test. Note that, however,
compiling with optimization enabled on NetBSD/macppc causes an initdb
failure (other two platforms are ok). After checking the asm code, we
are suspecting that might be a compiler(egcs) bug.

Tom Lane 724119a979 Modify int8 to not depend on sscanf(), and fix configure's test
for int8 support.  configure now checks only snprintf() for int8 support,
not sprintf and sscanf as it used to.  The reason for doing this is that
if we are supplying our own snprintf code (which does handle long long int),
we now only need working long long support in the compiler not in the
platform's C library.  I have verified that int8 now passes regression test
on HPUX 9, and I think it should work on SunOS 4.1.* and other older
platforms if gcc is used.

Marc G. Fournier 3b3ffc8d97 From: Magnus Hagander <mha@sollentuna.net>
Here is a first patch to cleanup the backend side of libpq.
This patch removes all external dependencies on the "Pfin" and "Pfout" that
are declared in pqcomm.h. These variables are also changed to "static" to
make sure.
Almost all the change is in the handler of the "copy" command - most other
areas of the backend already used the correct functions.
This change will make the way for cleanup of the internal stuff there - now
that all the functions accessing the file descriptors are confined to a
single directory.

Thomas G. Lockhart 6d5d673ca8 Be more careful to check input string lengths as well as values
when deciding whether a field is a year field.  Assume *anything* longer
 than 2 digits (if it isn't a special-case doy) is a valid year.
 This should fix the "Y1K" and "Y10K" problems
  pointed out by Massimo recently.
Check usage of BC to require a positive-valued year; before just used it
 to flip the sign of the year without checking. This led to problems
 near year zero.
Allow a 5 digit "concatenated date" of 2 digit year plus day of year.
Do 2->4 digit year correction for 6 and 5 digit "concatenated dates".
 Somehow forgot this originally. Guess not many folks use it...

Jan Wieck 1bbe55c79f Just one more bugfix - this time in cmp_abs (cannot imagine that
taking a logarithm with a 400 digit precision worked with that bug
in place).

Bruce Momjian f0fbd7b87e Some security, since we now have vsnprintf, I remade an old patch
with some extra ugly sprintfs fixed. More work in this area is
   needed still.

Thomas G. Lockhart 4d56dbd678 Change ordering of HAVE_TM_ZONE and HAVE_INT_TIMEZONE code blocks
to give HAVE_TM_ZONE priority. This fixes glibc2 machines and any other
 machine which passes both tests in configure.
Repair HAVE_TM_ZONE code which stuffs tm structure with date type values.
 Same problems as were originally there before v6.1, but never noticed.
Thanks to Oleg for nagging :)

Marc G. Fournier 54c3e65242 Oops, sorry...meant to commit the patch from Thomas for tzn->CTZName 1998-12-15 15:28:57 +00:00
Vadim B. Mikheev 83f558afdd tzn undeclared in FreeBSD, commented out. 1998-12-15 15:10:03 +00:00
Vadim B. Mikheev 3f7fbf85dc Initial MVCC code.
New code for locking buffer' context.

Marc G. Fournier 9396802f14 more cleanups...of note, appendStringInfo now performs like sprintf(),
where you state a format and arguments.  the old behavior required
each appendStringInfo to have to have a sprintf() before it if any
formatting was required.

Also shortened several instances where there were multiple appendStringInfo()
calls in a row, doing nothing more then adding one more word to the String,
instead of doing them all in one call.

Marc G. Fournier 7c3b7d2744 Initial attempt to clean up the code...
Switch sprintf() to snprintf()
Remove any/all #if 0 -or- #ifdef NOT_USED -or- #ifdef FALSE sections of
	code

Bruce Momjian ffb90a01fd Current multi-byte related codes have a bug with SQL_ASCII
support. Included patches will solve it and should be applied to
both trees.  Also, it fix the problem with \c command of psql when
switching different encoding databases.

Regression tests passed.

Thomas G. Lockhart 239564e9ef Add routines to help with single-byte (internal) character type support. 1998-12-13 23:36:48 +00:00
Thomas G. Lockhart f9f4004b7c Switch around conditional code so that HAVE_TM_ZONE takes precedence
over HAVE_INT_TIMEZONE. This may help out linux/glibc2 and Dec Alpha.
Included #error precompiler macros to catch cases where neither is defined
 but USE_POSIX_TIME is (shouldn't happen). Hopefully this isn't just
 a gcc-ism.

Thomas G. Lockhart 53b476798a Define routines and catalog entries for string min()/max() functions.
Extend new type coersion techniques to aggregates.
Clean up a few elog() messages.

Tom Lane 92eacaf523 Change exp() behavior to generate error on underflow rather
than silently returning zero on some machines.  Correct float8 regress test
to agree.  Also fix pow() overflow/underflow check to work correctly on
HPUX.

Vadim B. Mikheev 6beba218d7 New HeapTuple structure/interface. 1998-11-27 19:52:36 +00:00
Thomas G. Lockhart 643c7beddf Add text<->float8 and text<->float4 conversion functions.
This will fix the problem reported by Jose' Soares
 when trying to cast a float to text.
