Deprecating UDF
|
||||
--------------------------
|
||||
|
||||
* Initial design of UDF always used to be security problem. The most dangerous
|
||||
security holes when UDFs and external tables are used simultaneousky were
|
||||
fixed in FB 1.5. But even after it incorrectly declared (using SQL statement
|
||||
DECLARE EXTERNAL FUNCTION) UDF can easily cause various security issues like
|
||||
server crash or execution of arbitrary code. Therefore UDFs are deprecated
|
||||
in v.4. That means that UDFs can't be used with default configuration
|
||||
(parameter "UdfAccess" set to "None") and all sample UDF libraries (ib_udf,
|
||||
fbudf) are not distributed any more. Most of functions in that libraries
|
||||
were replaced with builtin analogs in previous versions and therefore
|
||||
already deprecated. A few remaining functions got safe replacement in UDR
|
||||
library "udf_compat", namely div, frac, dow, sdow, getExactTimestampUTC and
|
||||
isLeapYear. Users who still wish to use UDFs should set "UdfAccess" to
|
||||
"Restrict <path-list>". If you never used to modify this parameter before
|
||||
path-list is just UDF and resulting line in firebird.conf should be:
|
||||
UdfAccess = Restrict UDF
|
||||
Recommended long-term solution is replacing of UDF with UDR.

AppWizard has created this fbudf DLL for you.

|

This file contains a summary of what you will find in each of the files that
|
||||
make up your fbudf application.
|
||||
|
||||
fbudf.dsp
|
||||
This file (the project file) contains information at the project level and
|
||||
is used to build a single project or subproject. Other users can share the
|
||||
project (.dsp) file, but they should export the makefiles locally.
|
||||
|
||||
fbudf.cpp
|
||||
This is the main DLL source file.
|
||||
|
||||
fbudf.h
|
||||
This file contains your DLL exports.

||||
|
||||
/////////////////////////////////////////////////////////////////////////////
|
||||
Other standard files:
|
||||
|
||||
StdAfx.h, StdAfx.cpp
|
||||
These files are used to build a precompiled header (PCH) file
|
||||
named fbudf.pch and a precompiled types file named StdAfx.obj.

* Beware the SQL declaration for those functions has changed.
|
||||
* 2002.01.20 Claudio Valderrama: addMonth should work with negative values, too.
|
||||
* 2003.10.26: Made some values const and other minor changes.
|

* 2004.09.29 Claudio Valderrama: fix numeric overflow in addHour reported by

* "jssahdra" <joga.singh at inventum.cc>. Since all add<time> functions are
|
||||
* wrappers around addTenthMSec, only two lines needed to be fixed.

The library ibudf that comes with IB5, IB6 and FB has some generic routines.

|
||||
functionality. The first test is to build a separate small library. When those
|
||||
functions have been tested, they may be included in ibudf. This way, it's possible
|
||||
to experiment with fbudf without mangling the established library.
|
||||
|
||||
This is initially a MSVC project for Windows. It will be generalized later.
|
||||
It doesn't use ib_util because it relies on the engine providing return
|
||||
arguments when they are of type string.
|
||||
|
||||
Originally, this library intends to offer:
|
||||
|
||||
NVL => one for integers and the other for strings. This way, the overhead
|
||||
for strings can be avoided for integers.
|
||||
|
||||
NULLIF => same idea than before.
|
||||
|
||||
DOW (Day of Week) Monday, Tuesday, Wednesday ...
|
||||
SDOW(Short Day of Week) Mon, Tue, Wed, Thu ....
|
||||
|
||||
(
|
||||
The following two aren't necessary:
|
||||
SUBSTR: It has been superseded by internal SUBSTRING in Firebird.
|
||||
LEFT: You can use SUBSTRING(s from 1 for N) in Firebird
|
||||
)
|
||||
|
||||
RIGHT: This will work only for 1-byte charsets.
|
||||
|
||||
TRUNCATE / ROUND
|
||||
|
||||
(
|
||||
The following two are already in udflib:
|
||||
CEILING / FLOOR
|
||||
)
|
||||
|
||||
Date manipulation stuff ...
|
||||
Add a day, week, month, year to a date.
|
||||
|
||||
String <-> BLOB
|
||||
STRING2BLOB
|
||||
(Firebird already is capable of accepting a string to populate a blob on INSERT only.)
