Aubit 4GL SVN-Code

Maths builtins, CHAR UTF-8 truncation, UI protocol names, .NET runtime

ROUND/TRUNC/MOD/POW/EXP/LOGN/LOG10 were "not implemented" stubs and
failed to link. Implemented in builtin_d.c. ROUND and TRUNC work on the
decimal text rather than the double, so ROUND(1.005,2) gives 1.01 and
agrees with LET onto a DECIMAL(10,2); rounding the double gave 1.00.
Not added to std_funcs.c - that would reserve the names and break
programs defining their own, as tools/misql/coxxc04.4gl does.

CHAR(n) truncation could cut a UTF-8 character in half and leave invalid
bytes in the field. A4GL_trim_partial_char blanks a partial trailing
character; the field keeps its width and ASCII is unaffected.

UI protocol field names made consistent: MOVEWINDOW sent x/y, OPTIONS
sent option/value and WAITFOREVENT sent context, against uppercase
everywhere else. MOVEWINDOW was also emitting a malformed tag on both
XML paths (a stray / mid-tag). The Angular OPTIONS handler now accepts
the old and new names, so it works against either runtime.

dotnet/: .NET 8 runtime - 4GL types (CHAR/NCHAR as one character-counted
type, decimal for DECIMAL and MONEY, DateOnly for DATE, qualified
DATETIME and INTERVAL), SQL over a pluggable driver chosen by
A4GL_SQLTYPE with no provider dependency in the core, and the UI
protocol channel. 71 tests, plus a harness that runs the same probe
through both runtimes and diffs them.

Also adds 24 ExtJS command handlers that were never committed.

Restore the install file lists, so `make install` installs something.

The rewrite replaced a dozen lists that the old configure.in computed with
AC_SUBST(..., []) stubs. Every one of them feeds a
cp $(addprefix $(SOMEWHERE_DIR)/, $(SOMETHING_FILES)) $(DEST)
so an empty list became "cp <destination>" with no source, and the install
died at the first one. Worse, the executable lists were among them, so
even after getting past that nothing in bin was ever copied - an install
tree kept serving whatever binaries it already had, however many times the
source was rebuilt.

Restored, from what the old configure.in did:

FGLPC_SETTINGS_FILES listed from tools/4glpc/settings
ETC_FILES IMPORT_FILES CONVSQL_FILES listed from their directories
ROOT_FILES ALL_INC ALL_DOC explicit lists, existence filtered
ALL_SH AMAKE_SH AMAKE_BIN_EXE COMP_EXE RUNTIME_EXE the programs

AUBITETC was also being substituted as the literal '${prefix}/etc/aubit4gl'.
Makefile-common defines no 'prefix', so it collapsed to /etc/aubit4gl -
root owned, and the install failed for anyone not installing as root. It is
now expanded at configure time.

And the default prefix gets its writability check back: the old
configure.in fell back to a prefix under $HOME when /opt was not writable,
which the rewrite had dropped. An explicit --prefix is still honoured
exactly as given.

`make install` now completes and installs the programs.

An "object function" is no longer part of a class's dispatch table.

The grammar already marks these E_FTYPE_OBJECT and turns class lookup off
for them, but the code generator published every method the same way, so
a subclass's "object function sub" shadowed an inherited "function sub"
for ordinary instance calls. class.c now skips E_FTYPE_OBJECT in both
places it emits methods - memberFunctions[] and the
A4GL_add_datatype_function_i registrations - which leaves object
functions distinct from plain ones rather than a synonym for them.

Test 1818 passes. Suite: 1098 run, 23 failed, against 29 before today.

Fix negative DATETIME subtraction losing its magnitude.

Subtracting datetimes computed each field from the signed total, so a
negative difference gave every component its own minus sign:

seconds = -95703 -> "-1 -02:-35:-3"

which does not parse back, so the interval came out as zero with the sign
still attached - "-0 00:00" where "-1 02:35" was wanted. The positive
direction was always correct, which is why this went unnoticed.

Now the magnitude is split and a single leading sign applied. Test 1635
passes.

Fix tests 671, 672 and 673 - two defects in the tests themselves.

DATETIME FRACTION TO FRACTION is a degenerate qualifier and binding an
uninitialised one fails conversion, which aborted all three programs long
before they tested anything interesting. Removed those two fields; SECOND
TO SECOND and SECOND TO FRACTION are kept.

673 then failed with -217 on a second, older defect that the first had
been masking: its record field names and its CREATE TABLE column names had
drifted apart, and the explicit UPDATE/SELECT column lists used the record
spelling. Every name that differs is one the CREATE had shortened to fit
an 18 character identifier limit - aCharacterWithSize became
aCharacterWithSz, aIntervalMinPrecMin became aIntervalMinPreM, and so on -
so the lists asked for columns the table does not have. Corrected the 14
column-list entries; record definitions and r_. references are untouched.

All three now pass. Found with the debug trace restored in r13033.

Restore debug tracing, and make it the default again.

The runtime's tracing all sits inside #ifdef DEBUG, and nothing has been
defining DEBUG since the configure rewrite, so DEBUG=ALL has silently
produced nothing at all.

Three things were wrong. configure defaulted debug off, where the old
configure.in had it on unless --enable-optimised was given. --enable-debug
only added -g -O0 and never defined DEBUG, so the option did not work
either. And Makefile-common resets CFLAGS, so the flag cannot travel that
way - the template already had the right hook, DDEBUG=@DBGFLAG@, but
DBGFLAG was never substituted.

Now on by default, --enable-optimised to opt out. A run of test 671 that
previously gave no diagnostic at all now writes 450K of trace and names
the failing bind directly.

Mark the eight broken/invalid tests as expected failures.

484 491 527 674 contain no .4gl and no .expected at all - the directories
are empty, so there is nothing to run. 545 546 547 548 are CREATE/DROP
DATABASE tests whose own descriptions say the test is invalid.

All eight already declare obsolete_test=1, and functions_inc.sh has a skip
for that (IS_OBSOLETE_TEST), but it never fires - runs still report
Skipped: 0 and count them as failures. Listing them here uses the
mechanism that works; they can come back out if the skip is ever fixed.

Takes the unexpected-failure count from 18 to 10.

Test 1705 (ansi outer join) passes - drop it from the expected-to-fail lists.

Verified under -esqli -tui. It was listed in both the shared list and the
esqli one, and the shared list is unioned into every configuration, so it
had to come out of both.

Bump version to 1.8.1.

configure is regenerated along with it. configure.ac reads the version
with m4_esyscmd_s at autoreconf time, so a bump needs autoreconf before
configure - otherwise the build keeps writing plug-ins to the old
plugins-<version> directory while the runtime, which gets its version
from lib/generated/project.c at make time, looks in the new one.

Optional, consent-based build reporting in configure.

configure can now send one line to the project saying that a build
happened and which back ends were detected, so we have some idea how
many people build Aubit and which drivers are still worth maintaining.

It only asks on a terminal, defaults to no, and never runs in a scripted
or CI build. --enable-usage-report sends without asking,
--disable-usage-report never asks, and DO_NOT_TRACK is honoured. The
prompt shows exactly what would be sent, and nothing is sent when
building or running programs afterwards - only here, and only on a yes.

Note the prompt reads /dev/tty rather than stdin. Autoconf detaches
stdin near the top of every generated configure

test -n "$DJDIR" || exec 7<&0 </dev/null

so that configure can never block on input, which means a prompt reading
stdin silently does nothing at all.
