INI Library
Log Library
List Library
odbcinst
This is a
library of functions to help other code work with INI files. I am thinking
that a future, enhanced, version of this may become a stock Linux lib;
allowing more common use of INI files as a standard format of new config
files. In the meantime, it is used heavily by
ODBC
Config and
driver setup libs.
This library
amounts to a logging facility. It is used by ODBCINST and the unixODBC
Driver Manager. This will either get enhanced or replaced over the comming
months (probably enhanced). I would like to see it use UNIX logging.
This library
provides a set of small and simple functions for; creating, managing, and
deleting a single or doubly linked list. These functions serve to consolidate
ad-hoc linked list code in unixODBC and to provide a foundation for cursor
support.
This library
provides applications, and other unixODBC components, the ability to read/write
ODBC System Information without regard to where or how this information
is stored. It implements all major API's from the MS'isms and adds a few
convenience functions. One enhancement is the addition of a few APIs for
working with ODBC Config programs in a KDE/Qt based environment..
Tree
Library
SQI
Library
SQP
Library
This library
has been created to allow the storage of parsed SQL.
This library implements an ultra-lite
SQL Engine which uses text files for storage. It is complemented by an
ODBC driver to allow for a very open DBMS for small data sets. It is highly
recommended that all use of SQI be made via its ODBC driver; doing so will
allow the data source to be scaled up to a full DBMS as required and without
recompiling the source.
Development of SQI was driven by the desire
to incorporate ODBC support into KDE and by the concerns of having to implement
a full DBMS to allow its use. SQI is lite and open enough to satisfy these
concerns.
This library
is a lex/yacc based SQL parser. It was ripped out of SQI so that a common
SQL parse engine could be provided to all parts of unixODBC; in particular
to Drivers and non-SQL based data sources. Its current understanding of
the SQL syntax is quite limited but this should be extended in the future.
Also; the Tree lib should be used in some future version to store the SQL
syntax in a much more realistic manner.
odbcinst is a command line tool which
has been created for allowing people who are developing the install scripts/RPMs
for Drivers to be able to easily create/remove entries in odbc.ini and
odbcinst.ini. This command line tool is a compliment to the share library
of the same name (libodbcinst.so). This tool is a part of the odbcinst
component of unixODBC.
isql is a command line tool which allows
the user to execute SQL in batch or interactively. It has some interesting
options such as an option to generate output wrapped in an HTML table.
28.APR.99
Linked List Lib
A serious bug has been fixed in LST. Somewhere
along the line the init for nItems was removed. This caused wierd behavour
all over the place. It has been fixed.
04.APR.99
Linked List lib
A linked list lib (liblst.so) has been
added to the list of components in unixODBC. This linked list lib will
be used during the enhancement of some of the drivers (ie the mSQL driver).
The linked list lib may also be used to replace the ad-hoc linked list
code elsewhere in unixODBC. This lib has been introduced in unixODBC Alpha
2.0.1.
21.FEB.99
isql command line tool
A new 'monitor' tool has been created and
is called isql. isql is more than an interactive tool to submit SQL to
a data source. isql can be used in batch mode to extract data to a 'delimted'
file and it can be used to generate results wrapped in HTML.
isql has just been released as a component
in unixODBC Alpha 1.0.0 and will be included in all future versions. Check
it out and let us know what you think!
10.FEB.99
ODBCINST Lib in Beta
Mostly code cleanup issues remaining. A
bit more testing required. Being heavily used by the LinuxODBC DataManager
and ODBCConfig as well as the LinuxODBC DriverManager.
10.FEB.99
LOG Lib in Beta
Debugging issues with this lib seem to
have ceased. All features of this lib will continue to be tested as a side
affect of testing LinuxODBC components which use it.
10.FEB.99
INI Lib in Beta
The INI Lib has undergone some enhancements
(ie iniAppend()) and significant testing since its Alpha stage. This lib
will continue to be tested as LinuxODBC moves toward release 1.0
28.JAN.99
Created
libodbcinst.so.
This is an installer/setup API coded to be compatible with the MS spec.
Created
a
command line tool called odbcinst. This is
an interface to the libodbcinst API that can be used by install script/RPM
writers.
26.JAN.99
The following enhancements have
been made;
added iniObjectUpdate and iniPropertyUpdate
added iniObjectInsert and iniPropertyInsert
added iniCommit
enhanced iniPropertySeek
Not much left to do on this lib. Some ideas
are;
add iniRollback
preserver comments (and other stuff between objects)
streamline the code a bit
24.JAN.99
The INI Library has been rewritten
to allow for much more flexible use.
iniOpen now loads complete INI file into memory
iniOpen can optionaly create a new INI (if file does not exist)
iniPropertySeek improved to allow optional filter on Object, Property and
Value
iniObjectDelete and iniPropertyDelete added
iniObjectNext and iniPropertyNext added
iniObjectEOL and iniPropertyEOL added
Some functions coming soon are;
iniObjectUpdate and iniPropertyUpdate
iniObjectInsert and iniPropertyInsert
iniCommit
