to do that, but inconsistently.) Make bit type reject too short input,
too, per SQL. Since it no longer zero pads, 'zpbit*' has been renamed to
'bit*' in the source, hence initdb.
create_index_paths are not immediately discarded, but are available for
subsequent planner work. This allows avoiding redundant syscache lookups
in several places. Change interface to operator selectivity estimation
procedures to allow faster and more flexible estimation.
Initdb forced due to change of pg_proc entries for selectivity functions!

a separate statement (though it can still be invoked as part of VACUUM, too).
pg_statistic redesigned to be more flexible about what statistics are
stored. ANALYZE now collects a list of several of the most common values,
not just one, plus a histogram (not just the min and max values). Random
sampling is used to make the process reasonably fast even on very large
tables. The number of values and histogram bins collected is now
user-settable via an ALTER TABLE command.
There is more still to do; the new stats are not being used everywhere
they could be in the planner. But the remaining changes for this project
should be localized, and the behavior is already better than before.
A not-very-related change is that sorting now makes use of btree comparison
routines if it can find one, rather than invoking '<' twice.
give consistent results for all datatypes. Types float4, float8, and
numeric were broken for NaN values; abstime, timestamp, and interval
were broken for INVALID values; timetz was just plain broken (some
possible pairs of values were neither < nor = nor >). Also clean up
text, bpchar, varchar, and bit/varbit to eliminate duplicate code and
thereby reduce the probability of similar inconsistencies arising in
the future.
(which failed miserably during DST) to just compare against a time
derived from a timestamp value.
Certainly not a direct check for a correct result, but should work
at any time of year.
in CREATE TABLE, but give a warning notice. Clean up inconsistent
handling of defaults and NOT NULL flags from multiply-inherited columns.
Per pghackers discussion 28-Mar through 30-Mar.
truncating to integer. Remove regress test that checks whether
4567890123456789 can be converted to float without loss; since that's
52 bits, it's on the hairy edge of failing with IEEE float8s, and indeed
rint seems to give platform-dependent results for it.
mixed-signs. Previous effort left way too many minus signs, and was at
least as broken as the one before that :(
Clean up "ISO-style" time interval representation to omit zero fields if
there is at least one non-zero field. Supress some leading plus signs
when not necessary for clarity.
Replace every #ifdef __CYGWIN__ block with a cleaner TIMEZONE_GLOBAL macro
defined in datetime.h.
and revert documentation to describe the existing INHERITS clause
instead, per recent discussion in pghackers. Also fix implementation
of SQL_inheritance SET variable: it is not cool to look at this var
during the initial parsing phase, only during parse_analyze(). See
recent bug report concerning misinterpretation of date constants just
after a SET TIMEZONE command. gram.y really has to be an invariant
transformation of the query string to a raw parsetree; anything that
can vary with time must be done during parse analysis.
recommendation from Paul Vixie. Add a new abbrev() function to produce
abbreviated format as text. No forced initdb, but new function is not
available unless you do an initdb or add the pg_proc row manually.
comparison does not consider paths different when they differ only in
uninteresting aspects of sort order. (We had a special case of this
consideration for indexscans already, but generalize it to apply to
ordered join paths too.) Be stricter about what is a canonical pathkey
to allow faster pathkey comparison. Cache canonical pathkeys and
dispersion stats for left and right sides of a RestrictInfo's clause,
to avoid repeated computation. Total speedup will depend on number of
tables in a query, but I see about 4x speedup of planning phase for
a sample seven-table query.
I believe this should fix the issue that Philip Warner
noticed about the check for unique constraints meeting the
referenced keys of a foreign key constraint allowing the
specification of a subset of a foreign key instead of
rejecting it. I also added tests for a base case of
this to the foreign key and alter table tests and patches
for expected output.
Allow some operator-like tokens to be used as function names.
Flesh out support for time, timetz, and interval operators
and interactions.
Regression tests pass, but non-reference-platform horology test results
will need to be updated.

rather than just being aliases for int4in/int4out. Give type Oid a
full set of comparison operators that do proper unsigned comparison,
instead of reusing the int4 comparators. Since pg_dump is now doing
unsigned comparisons of OIDs, it is now *necessary* that we play by
the rules here. In fact, given that btoidcmp() has been doing unsigned
comparison for quite some time, it seems likely that we have index-
corruption problems in 7.0 and before once the Oid counter goes past
2G. Fixing these operators is a necessary step before we can think
about 8-byte Oid, too.
new separate relkind for views (per some discussion back in September).
I didn't force initdb, but rules regress test will show differences
until you do one.
cloned, rather than always cloning template1. Modify initdb to generate
two identical databases rather than one, template0 and template1.
Connections to template0 are disallowed, so that it will always remain
in its virgin as-initdb'd state. pg_dumpall now dumps databases with
restore commands that say CREATE DATABASE foo WITH TEMPLATE = template0.
This allows proper behavior when there is user-added data in template1.

the verbose-display formatting function text(), but will reconsider if
enough people object.
initdb forced.
(WAL logging for this is not done yet, however.) Clean up a number of really
crufty things that are no longer needed now that DROP behaves nicely. Make
temp table mapper do the right things when drop or rename affecting a temp

check, in favor of locking tables at first reference and holding that lock
throughout the statement.
on pghackers. Arrange for the sort ordering of general INET values
to be network part as major sort key, host part as minor sort key.
I did not force an initdb for this change, but anyone who's running
indexes on general INET values may need to recreate those indexes.
kibitzing from Tom Lane. Large objects are now all stored in a single
system relation "pg_largeobject" --- no more xinv or xinx files, no more
relkind 'l'. This should offer substantial performance improvement for
large numbers of LOs, since there won't be directory bloat anymore.
It'll also fix problems like running out of locktable space when you
access thousands of LOs in one transaction.
Also clean up cruft in read/write routines. LOs with "holes" in them
(never-written byte ranges) now work just like Unix files with holes do:
a hole reads as zeroes but doesn't occupy storage space.
INITDB forced!
as well allow DROP multiple INDEX, RULE, TYPE as well. Add missing
CommandCounterIncrement to DROP loop, which could cause trouble otherwise
with multiple DROP of items affecting same catalog entries. Try to
bring a little consistency to various error messages using 'does not exist',
'nonexistent', etc --- I standardized on 'does not exist' since that's
what the vast majority of the existing uses seem to be.

SQL92 semantics, including support for ALL option. All three can be used
in subqueries and views. DISTINCT and ORDER BY work now in views, too.
This rewrite fixes many problems with cross-datatype UNIONs and INSERT/SELECT
where the SELECT yields different datatypes than the INSERT needs. I did
that by making UNION subqueries and SELECT in INSERT be treated like
subselects-in-FROM, thereby allowing an extra level of targetlist where the
datatype conversions can be inserted safely.
INITDB NEEDED!
and the fmgr redesign.
It makes the homebrewn dl*() functions for more recent Versions of AIX
obsolete
by using the system dl*() functions instead.
It also fixes the expected file for the horology regression test.
Please regenerate configure from configure.in, I don't have the
environment/time.

(Don't forget that an alias is required.) Views reimplemented as expanding
to subselect-in-FROM. Grouping, aggregates, DISTINCT in views actually
work now (he says optimistically). No UNION support in subselects/views
yet, but I have some ideas about that. Rule-related permissions checking
moved out of rewriter and into executor.
INITDB REQUIRED!
There is still no effective difference but it will kick in once setuid
functions exist (not included here). Make old getpgusername() alias for
current_user.

Rearrange the test order slightly, and move the abstime test to the

Hand-patch the results for "1947" and for "solaris", so those may not
be exactly correct.
for views. Views are now have a "relkind" of
RELKIND_VIEW instead of RELKIND_RELATION.
Also, views no longer have actual heap storage
files.
The following changes were made
1. CREATE VIEW sets the new relkind
2. The executor complains if a DELETE or
INSERT references a view.
3. DROP RULE complains if an attempt is made
to delete a view SELECT rule.
4. CREATE RULE "_RETmytable" AS ON SELECT TO mytable DO INSTEAD ...
1. checks to make sure mytable is empty.
2. sets the relkind to RELKIND_VIEW.
3. deletes the heap storage files.
5. LOCK myview is not allowed. :)
6. the regression test type_sanity was changed to
account for the new relkind value.
7. CREATE INDEX ON myview ... is not allowed.
8. VACUUM myview is not allowed.
VACUUM automatically skips views when do the entire
database.
9. TRUNCATE myview is not allowed.
THINGS LEFT TO THINK ABOUT
o pg_views
o pg_dump
o pgsql (\d \dv)
o Do we really want to be able to inherit from views?
o Is 'DROP TABLE myview' OK?

didn't hear anything about, but which would
have broken with the function manager changes
anyway.
Well, this patch checks that a unique constraint
of some form (unique or pk) is on the referenced
columns of an FK constraint and that the columns
in the referencing table exist at creation time.
The former is to move closer to SQL compatibility
and the latter is in answer to a bug report.
I also added a basic check of this functionality
to the alter table and foreign key regression
tests.

Update functions to new-style fmgr, make BIT and VARBIT be binary-
equivalent, add entries to allow these types to be btree indexed,
correct a few bugs. BIT/VARBIT are now toastable, too.
NOTE: initdb forced due to catalog updates.
on myself to do something about the non-self-consistency of the inet
comparison functions. The results are probably still semantically wrong
(inet and cidr should have different comparison semantics, I think)
but at least the boolean operators now agree with each other and with
the sort order of indexes on inet/cidr.
(Sorry, couldn't help it...)
Removed type filename as well, since it's unused and probably useless.
INITDB FORCED, because pg_rewrite columns are now plain text again.
the planner may try to generate them as a result of transitivity of the
existing int2-vs-int4 and int4-vs-int8 operators. In fact, it is now
necessary that mergejoinable cross-datatype operators form closed sets.
Add an opr_sanity regress test to detect missing operators.
varlena elements work now. Allow assignment to previously-nonexistent
subscript position to extend array, but only for 1-D arrays and only
if adjacent to existing positions (could do more if we had a way to
represent nulls in arrays, but I don't want to tackle that now).
Arrange for assignment of NULL to an array element in UPDATE to be a
no-op, rather than setting the entire array to NULL as it used to.
(Throwing an error would be a reasonable alternative, but it's never
done that...) Update regress test accordingly.
type different from input type but are expecting ExecAgg to insert the
first non-null input as the starting transition value. This has always
been verboten, but wasn't checked for until now...
There's now only one transition value and transition function.
NULL handling in aggregates is a lot cleaner. Also, use Numeric
accumulators instead of integer accumulators for sum/avg on integer
datatypes --- this avoids overflow at the cost of being a little slower.
Implement VARIANCE() and STDDEV() aggregates in the standard backend.
Also, enable new LIKE selectivity estimators by default. Unrelated
change, but as long as I had to force initdb anyway...
Include updates for the comment.sql regression test.
Implement SET SESSION CHARACTERISTICS and SET DefaultXactIsoLevel.
Implement SET SESSION CHARACTERISTICS TRANSACTION COMMIT
and SET AutoCommit in the parser only.
Need to add code to actually do something.
Implement WITHOUT TIME ZONE type qualifier.
Define SCHEMA keyword, along with stubbed-out grammar.
Implement "[IN|INOUT|OUT] [varname] type" function arguments
in parser only; INOUT and OUT throws an elog(ERROR).
Add PATH as a type-specific token, since PATH is in SQL99
to support schema resource search and resolution.
Now the to_timestamp() support WW,W,J,SSSS,DDD conversion from strings and
the am/pm bug is fixed, the to_char() use week-of-year (WW) full compatible
with Oracle.
This patch update relevant regress-tests and docs too.

inputs have been converted to newstyle. This should go a long way towards
fixing our portability problems with platforms where char and short

- I was unable to compile ecpg due to the ":=" instead of "=" in defining
LIBPQDIR and some other variables in Makefile.global.in
- pg_id (and also pg_encoding) executable was not removed during "make
clean" - there was no $(X) appended to the executable name for rm
- I have added result for int2, int4, float8 and geometry regression tests
- int2, int2 - yet another message for too large numbers ;-)
- float8 - it is problably a bug in the newlib C library - it has no
error message for numbers with exponent -400
- geometry - differences in precision of float numbers
- I have added appropriate lines into resultmap file
- I have modified the script regress.sh to use "case" statement when testing
the hostname. For cygwin the script is called with "i686-pc-cygwin" (on my
machine) as a parameter and this was not catched with the "if" statement.
The check was done for PORTNAME (win) and not HOSTNAME (i.86-pc-cygwin*).
The patch for described modifications is included.
All this modifications can be applied to "current" tree too.
The compilation was done on CygwinB20.1 with gcc 2.95, cygipc library 1.05.

after trying to resolve the item as an input-column name. This allows us
to be compliant with the SQL92 spec for queries that fall within the spec,
while still accepting the same out-of-spec queries as 6.5 did. You'll only
lose if there is an output column name that is the same as an input
column name, but doesn't refer to the same value. 7.0 will interpret
such a GROUP BY spec differently than 6.5 did. No way around that, because
6.5 was clearly not spec compliant.
Implement TIME WITH TIME ZONE type (timetz internal type).
Remap length() for character strings to CHAR_LENGTH() for SQL92
and to remove the ambiguity with geometric length() functions.
Keep length() for character strings for backward compatibility.
Shrink stored views by removing internal column name list from visible rte.
Implement min(), max() for time and timetz data types.
Implement conversion of TIME to INTERVAL.
Implement abs(), mod(), fac() for the int8 data type.
Rename some math functions to generic names:
round(), sqrt(), cbrt(), pow(), etc.
Rename NUMERIC power() function to pow().
Fix int2 factorial to calculate result in int4.
Enhance the Oracle compatibility function translate() to work with string
arguments (from Edwin Ramirez).
Modify pg_proc system table to remove OID holes.
the to_char() source code is large, here are regression tests for
numeric/timestamp/int8 part. It is probably enough test for formatting

few probable.

interpret a column name as an output column alias (targetlist AS name),
ather than a real column name as it ought to. According to the spec,
only ORDER BY should look at output column names. I left in GROUP BY's
willingness to use an output column number ('GROUP BY 2'), even though
this is also contrary to the spec --- again, only ORDER BY is supposed
to accept that. But there is no possible reason to want to GROUP BY
an integer constant, so keeping this old behavior won't break any
SQL-compliant queries. DISTINCT ON will behave the same as GROUP BY.
Change numerology regress test, which depended on the incorrect
behavior.
erroneous expected output for RESET DateStyle: should be ISO now.
Fix run_check.sh so that test postmaster is started with PGDATESTYLE=ISO,

selectivity functions and make the r-tree operators use them. The
estimation functions themselves are just stubs, unfortunately, but
perhaps someday someone will make them compute realistic estimates.
Change pg_am so that the optimizer can reliably tell the difference

an r-tree index can be scanned in '<<' order, which is not right AFAIK.
Repair broken negator links for network_sup and related ops.

Make "INTERVAL" reserved word allowed as a column identifier in gram.y.
Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility

date.{h,c} now deals with date, time types.
timestamp.{h,c} now deals with timestamp, interval types.
nabstime.{h,c} now deals with abstime, reltime, tinterval types.
Make NUMERIC a known native type for purposes of type coersion. Not tested.
accesses versus sequential accesses, a (very crude) estimate of the
effects of caching on random page accesses, and cost to evaluate WHERE-
clause expressions. Export critical parameters for this model as SET
variables. Also, create SET variables for the planner's enable flags
(enable_seqscan, enable_indexscan, etc) so that these can be controlled
more conveniently than via PGOPTIONS.
Planner now estimates both startup cost (cost before retrieving
first tuple) and total cost of each path, so it can optimize queries
with LIMIT on a reasonable basis by interpolating between these costs.
Same facility is a win for EXISTS(...) subqueries and some other cases.
Redesign pathkey representation to achieve a major speedup in planning

Previously, dates falling within Unix system time range were run through

src/backend/port/snprintf.c, so int8 is probably broken in every platform
that hasn't a native snprintf/vsnprintf. The type itself worked as
expected, only the output was wrong. Anyway, this patch should be checked
in other platforms.
- The regression tests for int2 and int4, which were broken due to
differences in the error messages, are fixed.
- The regression test for float8, which was broken in the reference
platform, is also fixed. I don't know if the new file (float8-OSF1.out)
will work on other platforms, but it might be worth to try it.
- Two new template files are provided (alpha_cc, which includes
optimization, and alpha_gcc), and src/templates/.similar is updated
accordingly. src/templates/alpha should be removed from the distribution.
*IMPORTANT NOTE*: I don't know if you can use gcc to compile postgres;
I've written the alpha_gcc file because alpha_cc has some flags that are
specific to DEC C.
- There is a (very basic) Digital Unix specific FAQ in
doc/FAQ_DigitalUnix.

HPUX.
mistakes in creating pg_operator table. NOTE: right now, this will
fail because of conflicting definitions for point @ path operator.
I trust we're gonna fix that.
for against a just updated CVS tree. It contains
Partial new rewrite system that handles subselects, view
aggregate columns, insert into select from view, updates
with set col = view-value and select rules restriction to
view definition.
Updates for rule/view backparsing utility functions to
handle subselects correct.
New system views pg_tables and pg_indexes (where you can
see the complete index definition in the latter one).
Enabling array references on query parameters.
Bugfix for functional index.
Little changes to system views pg_rules and pg_views.
The rule system isn't a release-stopper any longer.
But another stopper is that I don't know if the latest
changes to PL/pgSQL (not already in CVS) made it compile on
AIX. Still wait for some response from Dave.

here is the patch that includes PL/pgSQL into the build
(currently with make errors ignored) and adds a regression
test for it. A clean build and regression ran fine here.
Can you please apply it?
The tar should be extracted in /usr/local/src/pgsql and
creates the following files:
src/pl/Makefile
called by toplevel GNUmakefile and for now only calls
src/pl/plpgsql/Makefile
src/pl/plpgsql/Makefile
calls src/pl/plpgsql/src/Makefile (here the call to
make ignores build errors - this must be changed
later for the final release).
src/test/regress/input/install_plpgsql.source
SQL script installing PL/pgSQL language in regression
database. Will be modified by .../input/Makefile to
point to correct PGLIB directory where plpgsql.so
gets installed.
src/test/regress/output/install_plpgsql.source
expected output for installation script.
src/test/regress/sql/plpgsql.sql
the main regression test. It tests functions and
triggers written in PL/pgSQL including views that use
supportfunctions in this language.
src/test/regress/expected/plpgsql.out
the expected output for the above regression test.
make_plpgsql.diff
patch that adds some lines to
src/GNUmakefile.in
src/test/regress/expected/Makefile
src/test/regress/input/Makefile
src/test/regress/output/Makefile
src/test/regress/sql/Makefile
src/test/regress/sql/tests
test passes. Interestingly, the fix involves no changes or special
cases in the union test and actually removes a special case for the
numerology test. Thus, following the strategy outlined below is a
definite improvement over the previous situation.
Cheers,
Brook

I have attached a patch to allow GROUP BY and/or ORDER BY function or
expressions. Note worthy items:
1. The expression or function need not be in the target list.
Example:
SELECT name FROM foo GROUP BY lower(name);
2. Simplified the grammar to use expressions only.
3. Cleaned up earlier patch in this area to make use of existing
utility functions.
3. Reduced some of the members in the SortGroupBy parse node. The
original data members were redundant with the new expression node.
(MUST do a "make clean" now)
4. Added a new parse node "JoinUsing". The JOIN USING clause was
overloading this SortGroupBy structure. With the afore mentioned
reduction of members, the two clauses lost all their commonality.
5. A bug still exist where, if a function or expression is GROUPed BY,
and an aggregate function does not include a attribute from the
expression or function, the backend crashes. (or something like
that) The bug pre-dates this patch. Example:
SELECT lower(a) AS lowcase, count(b) FROM foo GROUP BY lowcase;
*** BOOM ***
--Also when not in target list
SELECT count(b) FROM foo GROUP BY lower(a);
*** BOOM AGAIN ***
I have implemented a framework of encoding translation between the
backend and the frontend. Also I have added a new variable setting
command:
SET CLIENT_ENCODING TO 'encoding';
Other features include:
Latin1 support more 8 bit cleaness
See doc/README.mb for more details. Note that the pacthes are
against May 30 snapshot.

Add additional tests in strings for conversions of the "name" data type.
Test SQL92 string functions such as SUBSTRING() and POSITION().
Fix geometry tests to reflect code fixed by Gautam.
Update error messages.
Everything (except of course random) passes on my netbsd box except int2,
int4, oidint2, and oidint4; all fail because of error message differences.
Below are some patches to the expectations to correct the problem by creating
*-NetBSD.out files.
Hi, here are patches I promised (against 6.3.2):
* character_length(), position(), substring() are now aware of
multi-byte characters
* add octet_length()
* add --with-mb option to configure
* new regression tests for EUC_KR
(contributed by "Soonmyung. Hong" <hong@lunaris.hanmesoft.co.kr>)
* add some test cases to the EUC_JP regression test
* fix problem in regress/regress.sh in case of System V
* fix toupper(), tolower() to handle 8bit chars
note that:
o patches for both configure.in and configure are
included. maybe the one for configure is not necessary.
o pg_proc.h was modified to add octet_length(). I used OIDs
(1374-1379) for that. Please let me know if these numbers are not
appropriate.
1. Remove the char2, char4, char8 and char16 types from postgresql
2. Change references of char16 to name in the regression tests.
3. Rename the char16.sql regression test to name.sql. 4. Modify
the regression test scripts and outputs to match up.
Might require new regression.{SYSTEM} files...

Included are patches intended for allowing PostgreSQL to handle
multi-byte charachter sets such as EUC(Extende Unix Code), Unicode and
Mule internal code. With the MB patch you can use multi-byte character
sets in regexp and LIKE. The encoding system chosen is determined at
the compile time.
To enable the MB extension, you need to define a variable "MB" in
Makefile.global or in Makefile.custom. For further information please
take a look at README.mb under doc directory.
(Note that unlike "jp patch" I do not use modified GNU regexp any
more. I changed Henry Spencer's regexp coming with PostgreSQL.)
I thought it would be a good idea to ensure that the new view
permission model will not get broken by subsequent
fixes/changes. So I wrote a little regression test for it.
There is an ugly thing in this regression test. It creates
temporary a test user that is required for the tests. The
user is removed at the end of the test, but if sometimes the
regression suite is aborted or crashes exactly here, the test
user will lay around in the pg_shadow. Don't have a clue how
to get around.
if an operating specific expected file exists, use that for the comparison.
This allows for "legit" differences between results, like the "Result too
large" message vs "Math result not representable" ...
Also, have the failed diffs get output to regression.diffs so that its easy to
view those tests that failed
Subject: [PATCHES] Re: [PORTS] AIX 6.1 fixes...
Here are the patches for the two things that wouldn't make it thru the AIX
compiler. The geo_ops.c change is harmless I believe. The nbtcompare.c patch
fixes me, but I don't know about any other ports. Maybe wait on that one
until Vadim decides what to do about the unsigned vs signed chars varlena
issue.
Subject: [PATCHES] Patches for boolean, timespan and reltime regression tests.
Hi All,
Here are a couple of patches to the regression tests to introduce
some specific ordering to the results.
I've only made changes to the queries that were exhibiting differences
on my regression runs.
This will also have the side effect of testing the ordering code for
the boolean and some of the time types.
the DROP TABLE calls from the destroy.sql file to the 'types' .sql files,
so that they are self-contained
btree_index, hash_index and misc all fail as there seems to be missing
a 'misc.out' expected file...have asked Thomas for one...
OK, here are a passel of patches for the geometric data types.
These add a "circle" data type, new operators and functions
for the existing data types, and change the default formats
for some of the existing types to make them consistant with
each other. Current formatting conventions (e.g. compatible
with v6.0 to allow dump/reload) are supported, but the new
conventions should be an improvement and we can eventually
drop the old conventions entirely.
For example, there are two kinds of paths (connected line segments),
open and closed, and the old format was
'(1,2,1,2,3,4)' for a closed path with two points (1,2) and (3,4)
'(0,2,1,2,3,4)' for an open path with two points (1,2) and (3,4)
Pretty arcane, huh? The new format for paths is
'((1,2),(3,4))' for a closed path with two points (1,2) and (3,4)
'[(1,2),(3,4)]' for an open path with two points (1,2) and (3,4)
For polygons, the old convention is
'(0,4,2,0,4,3)' for a triangle with points at (0,0),(4,4), and (2,3)
and the new convention is
'((0,0),(4,4),(2,3))' for a triangle with points at (0,0),(4,4), and (2,3)
Other data types which are also represented as lists of points
(e.g. boxes, line segments, and polygons) have similar representations
(they surround each point with parens).
For v6.1, any format which can be interpreted as the old style format
is decoded as such; we can remove that backwards compatibility but ugly
convention for v7.0. This will allow dump/reloads from v6.0.
These include some updates to the regression test files to change the test
for creating a data type from "circle" to "widget" to keep the test from
trashing the new builtin circle type.
