Re-reverse engineered index meta information layout in JET 4
file format, based particularly on jackcess (Java) JET/Access
database library (https://github.com/jahlborn/jackcess), and
hexdumps of JET 4 database index meta information. Based both
on byte counting of jackcess reading of index definitions and
also expected flag values (0x80, 0x89, etc), the flags of JET 4
index definition are 4 bytes later than mdbtools previously thought.
See IndexData.read() and private static class Jet4Format in
src/main/java/com/healthmarketscience/jackcess/impl/IndexData.java
src/main/java/com/healthmarketscience/jackcess/impl/JetFormat.java
in jackcess source for layout reference.
Now appears to get sensible "CREATE INDEX"/"CREATE UNIQUE INDEX"
behaviour on export to PostgreSQL schema.
Also added extensive index definition byte layout reference to top
of src/libmdb/index.c for ease of reference, plus more debugging
assistance (and comments of phases reading index for readability).
This adds support for reading OLE objects to the ODBC driver. The APIs
for reading OLE appear somewhat idiosyncratic, so we read the string
fully and stash it in a static variable.
Tested by reading an old Access database, with checking for memory leaks.
Most 64-bit environments use 64 bit longs and 32 bit ints; as such,
comparing an int to LONG_MIN/MAX makes no sense. Since SQL LONGs
appear limited to 32 bits, I assume INT_MIN/MAX was intended.
'gnome-doc-utils' is a rather large dependency on OS X, and the build
system has checks for gnome-doc-utils surrounding its use, but the
autoconf check errors out in its absence.
The memory for sql->bound_values is now freed by mdb_sql_reset, so these values no longer should be freed in dump_results_pp. Also, this fixes a memory leak that was occurring when results were not being pretty printed.
SQL engine was being reset in both dump_results functions. Rather than having several different functions responsible for resetting the engine depending on the circumstances, the reset now only occurs in run_query, the same function where the query is executed.
One can now compile with CFLAGS="-std=c99 -D_POSIX_C_SOURCE=1 -pedantic"
Trade getopt.h function for glib equivalents:
This mean all utilities now have long option names.
Adjust manuals and bash_completion accordingly.
Added missing manual and bash_completion for mdb-import.
