Version 0.9.0
|
|
=============
|
|
|
|
MDB Tools is under new management! Update your bookmarks and tell your favorite
|
|
search engine that this is our new home on the WWW:
|
|

https://github.com/mdbtools/mdbtools
|
|
|
|
MDB Tools 0.9.0 builds off the fork of cyberemissary on GitHub, collects many
|
|
years of unapplied patches, and includes a number of internal improvements.
|
|
Besides a host of security fixes, GLib is now completely optional, files can
|
|
be opened completely in-memory, and many global variables have been eliminated
|
|
to facilitate thread safety.
|
|
|
|
The core library, libmdb, is believed to be thread-safe in the sense that
|
|
several handles can be opened simultaneously and passed between threads.
|
|
However, individual handles are NOT thread-safe, so don't try to do work
|
|
on a single handle from multiple threads without implementing your own
|
|
locking mechanism.
|
|
|
|
The auxiliary libraries, libmdbsql and ODBC, still have some non-reentrant
|
|
function calls. Thread safety is not promised, though the situation is
|
|
significantly improved from the 0.7 days.
|
|
|
|
The ABI has some slight changes (mostly having to do with struct layouts) so
|
|
you'll need to bump your SO numbers and such. The main changes to the API are
|
|
the introduction of a new function for in-memory parsing:
|
|
|
|
MdbHandle *mdb_open_buffer(void *buffer, size_t len, MdbFileFlags flags);
|
|
|
|
And the modification of the "mdb_set_date_fmt" function to include a handle
|
|
parameter, so that date formats can be set in a non-global fashion:
|
|
|
|
void mdb_set_date_fmt(MdbHandle *mdb, const char *);
|
|
|
|
The above function is the most common reason that old projects will fail to
|
|
compile on 0.9, and the fix is straightforward.
|
|
|
|
The previously-deprecated functions mdb_init() and mdb_exit() have been
|
|
removed. These functions did nothing; any calls to them should be excised with
|
|
prejudice.
|
|
|
|
This release introduces two new CLI tools (mdb-count and mdb-queries) and
|
|
deprecates mdb-array, mdb-header, and mdb-parsecsv. Several man pages have been
|
|
added or otherwise brought up to date.
|
|
|
|
The GNOME-based GUI tool that formerly shipped with MDB Tools has been moved to
|
|
a separate project, here:
|
|
|
|
https://github.com/mdbtools/gmdb2
|
|
|
|
It seems to compile but should probably be classified as abandonware. The
|
|
project uses a deprecated GUI toolkit, and as such gmdb2 is no longer included
|
|
in Linux distros that used to carry it.
|
|
|
|
Version 0.7.1
|
|
=============
|
|
autogen.sh is no more. Use "autoreconf -if" to bootstrap the configuration.
|
|
|
|
autoconf/automake has been updated to more recent standards.
|
|
- config.guess config.sub depcomp install-sh ltmain.sh missing ylwrap
|
|
files are now in build-aux/ directory
|
|
You'll now need autoconf >= 2.58
|
|
|
|
An experimental (buggy) version of ODBC driver that supports UCS-2 interface
|
|
is now available: libmdbodbcW.so
|
|
Note that libmdbodbc supports UTF-8 really well, so that this is usually not
|
|
needed.
|
|
|
|
Version 0.3
|
|
===========
|
|
The organization of the project files has changed a bit from that last release.
|
|
The autoconf stuff has been moved to the root directory. The include directory
|
|
has also been moved from src/include to include
|
|
