Replace the jerry-built UTF-16 => Latin-1 code path with a cross-platform wcstombs solution that emits UTF-8.
This adds an element to the end of the MdbHandle struct, but should not break any existing code.
A run-time option could be added later to emit other encodings, but people who care about such things can just use the iconv code path.
mdb_init() and mdb_exit() have done nothing for a while.
mdb_get_coltype_string() and mdb_coltype_takes_length() were previously
removed, but remained in the header file by accident.
* Separate -D (date only) and -T (date/time) format options in mdb-export and mdb-json
* New public mdb_set_shortdate_fmt() function in libmdb
* New private(ish) mdb_col_is_shortdate() function
I'm calling it "shortdate" in order to preserve the existing API.
See https://github.com/mdbtools/mdbtools/issues/12
This should fix long-standing complaints about the default bind size
without causing undue memory inflation in existing applications.
Could make this adjustable on the command line later.
Supersedes:
https://github.com/mdbtools/mdbtools/pull/137
Quickstart (requires Clang 6 or later):
$ export LIB_FUZZING_ENGINE=/path/to/fuzzing/library.a
$ ./configure --enable-fuzz-testing
$ make
$ cd src/fuzz
$ make fuzz_mdb
$ ./fuzz_mdb
Also add a new `mdb_open_buffer function` to facilitate in-memory
fuzz-testing. This requires fmemopen, which may not be present on all
systems. The internal API has been reworked to use file streams instead
of file descriptors. This allows reading from memory and reading from
files using a consistent API.
* Replace backend_is_init (formerly is_init) with relationships_table
* Remove deprecated functions that used static variables
* Move static "bound" variable to MdbHandle as relationships_values
Attempt to make the backend handling logic thread-safe. This removes the
last MDB_CONSTRUCTOR. Also get rid of some JAVA junk and make the
remaining static variables in backend.c constant. Finally remove some
obsolete fields from MdbFile.
Add a shim implementing half-assed versions of most of the GLib
functions used by MDB Tools. If GLib is detected at compile-time,
use it, otherwise use the shim.
This work is not complete, as the option-parsing code is not yet
implemented - so most of the command-line tools crash.
If a host project has -Wstrict-prototypes enabled, the mdbtools header
results in warnings. Turn on -Wstrict-prototypes for the whole project
so that these never occur again.
Some Access 2010 files use 0x03 as the version number rather than
0x0103. For this reason I have changed the call to mdb_get_int32 to
mdb_get_byte.
In addition, according to the Library of Congress page:
https://www.loc.gov/preservation/digital/formats/fdd/fdd000463.shtml
Access 2016 uses 0x05 as the version number. I have inferred from the
Wikipedia page that Access 2013 likely uses 0x04.
Adds "-B" (--boolean-words) option to mdb-export, which will reconfigure
mdb/data.c to export TRUE/FALSE for boolean values instead of 1/0. The
option is needed to support BOOLEAN fields on PostgreSQL, which will not
implicitly cast bare 1/0 into a BOOLEAN value. Value literals are the
SQL TRUE/FALSE, and _quoted_ words meaning true/false and _quoted_
'1'/'0'. With this flag the SQL TRUE/FALSE values are output, which should
work with several SQL databases.
PostgreSQL Reference:
http://www.postgresql.org/docs/current/static/datatype-boolean.html
This commit adds another binary output conversion option to convert
binary blobs into hexadecimal notation, similar to the output of the
following command:
xxd -p binaryfile.bin | tr -d '\n'
(In other words, a single line string of hexadecimal characters
representing a binary blob)
When exporting SQL INSERT statements for SQLite and PostgreSQL and when
the hexadecimal notation is specified with 'mdb-export -b hex ...',
special consideration is given to ensure that binary blobs are safely
written to the SQLite or PostgreSQL database.

__attribute__ does not exist in Visual Studio. Therefore replaced wherever it appeared with a macro:
Redefines MDB_DEPRECATED to support Visual Studio
Define a Constructor MACRO so that __attribute__((constructor/destructor)) behavior is achieved in Visual Studio.
Just using generate_table_schema through mdb_print_schema deletes the purpose of a very good tool. generate_table_schemas is a rewrite of generate_table_schema but sends the data to a char* instead of FILE*. There is NO fmemopen() or similar in Visual Studio, so there is NO way to access memory through a FILE* except for first writing to the disk and then reading from the disk in memory.
I cannot suggest how to handle the case when td == 0 for the dates. The databases I work with often have just 00:00:00 in the DateTime column which is not consistent with the rest of the column either, but I have to deal with it somehow.
Leaving void* where char* is needed as a function parameter returns a compilation error in Visual Studio.
These functions now use the __attribute__((constructor)) & destructor.
Old names were keep for compatibility
Also put __attribute__((deprecated)) in mdbtools.h for all deprecated
functions.
The major new feature in Access 2007 where so called complex columns.
These can be multivalued fields, attachments, or MEMO fields with
version history. All of them are implemented using hidden helper tables,
and the column itself has type MDB_COMPLEX (0x12) which is basically a
long int used as a key.
This commit adds basic support for this complex type to libmdb.
These were the only symbols exported not starting with mdb_
Old names stay available as aliases
Bumped libmdb version to 2.0.1
Added these prototypes to mdbtools.h: Fixes compilation warning
Added mdb_insert_row prototype to mdbtools.h: Fixes compilation warning
