|
||||
|
||||
The library is stable. With the 0.8 release, the last known bug has been
|
||||
resolved. The library now has transactions, many more environment
|
||||
management functions (hash params, shm, etc), and open transactions,
|
||||
cursors and databases are tracked and properly cleaned up during finalization,
|
||||
or at least when env.close is called. The library is size stable (no leaks)
|
||||
and is being used in a heavy production environment with great reliability.
|
||||
|
||||
The future:
|
||||
|
||||
There are numerous DB controls that are not yet in the interface, as well
|
||||
as handling sequences and other DB features. There has been no call for
|
||||
them yet, so they linger.
|
||||
|
||||
The build system is a little weak. DB can be installed in so many different
|
||||
places and variety of versions, making version selection tricky. There is
|
||||
a complication, in that it is not enough for the compiler chain to find the
|
||||
db.h and libraries, the build needs to find the exact db.h, because symbols
|
||||
are extracted from it to generate the Ruby-side defines. It would be nice to
|
||||
fix the build process and to turn it into a Gem.
|
||||
|
||||
Numerous, more ruby-like, methods need to be added. Probably in just a .rb
|
||||
file to wrap and increase the ease of use for the core methods. The methods
|
||||
do not deal with variable argument lists as they are largely faithful to
|
||||
the DB API. But methods like cursor#next, cursor#first, and cursor.each
|
||||
are appropriate.
|
||||
|
||||
9-Feb-2006
|
||||
Done:
|
||||
All common environment, database and cursor functions are in. They are also
|
||||
_fully_ unit tested and are in production under heavy use. There are a
|
||||
few missing, like pget.
|
||||
|
||||
Limitations:
|
||||
If Ruby process exits and there are any open cursors (your program did not
|
||||
close them) the process will SEGV. This is due to dbc_free trying to close
|
||||
the cursor(s), even though the DB may already be closed. This will be fixed
|
||||
