Library Version Changes
|
|
|
|
=======================
|
|
|
|
|
|
|
|
Major Version
|
|
|
|
=============
|
2002-12-14 20:45:46 +01:00
|
|
|
|
|
|
|
The major version number should be updated whenever the source of the
|
|
|
|
library changes to make it binary incompatible. Such changes include,
|
|
|
|
but are not limited to:
|
|
|
|
|
|
|
|
1. Removing a public function or structure (or typedef, enum, ...)
|
|
|
|
|
|
|
|
2. Modifying a public functions arguments.
|
|
|
|
|
|
|
|
3. Removing a field from a public structure.
|
|
|
|
|
2003-01-11 05:58:44 +01:00
|
|
|
4. Adding a field to a public structure, unless steps have been
|
2002-12-14 20:45:46 +01:00
|
|
|
previously taken to shield users from such a change, for example by
|
|
|
|
such structures only ever being allocated/instantiated by a library
|
|
|
|
function which would give the new field a suitable default value.
|
|
|
|
|
|
|
|
Adding a new function would NOT force an increase in the major version
|
|
|
|
number. When the major version is increased all applications which
|
|
|
|
link to the library MUST be recompiled - this is not desirable. When
|
|
|
|
the major version is updated the minor version gets reset.
|
|
|
|
|
|
|
|
Minor Version
|
|
|
|
=============
|
|
|
|
|
|
|
|
The minor version number should be updated whenever the functionality
|
|
|
|
of the library has changed, typically and change in source code
|
|
|
|
between releases would mean an increase in the minor version number so
|
|
|
|
long as it does not require a major version increase.
|
|
|
|
|
|
|
|
Minimizing Changes
|
|
|
|
==================
|
|
|
|
|
|
|
|
When modifying public functions arguments, steps should be taken to
|
|
|
|
maintain binary compatibility across minor PostgreSQL releases (e.g. the
|
|
|
|
7.2 series, the 7.3 series, the 7.4/8.0 series). Consider the following
|
|
|
|
function:
|
|
|
|
|
|
|
|
void print_stuff(int arg1, int arg2)
|
|
|
|
{
|
|
|
|
printf("stuff: %d %d\n", arg1, arg2);
|
|
|
|
}
|
|
|
|
|
|
|
|
If we wanted to add a third argument:
|
|
|
|
|
|
|
|
void print_stuff(int arg1, int arg2, int arg3)
|
|
|
|
{
|
|
|
|
printf("stuff: %d %d %d\n", arg1, arg2, arg3);
|
|
|
|
}
|
|
|
|
|
|
|
|
Then doing it like this:
|
|
|
|
|
|
|
|
void print_stuff2(int arg1, int arg2, int arg3)
|
|
|
|
{
|
|
|
|
printf("stuff: %d %d %d\n", arg1, arg2, arg3);
|
|
|
|
}
|
|
|
|
|
|
|
|
void print_stuff(int arg1, int arg2)
|
|
|
|
{
|
|
|
|
print_stuff(arg1, arg2, 0);
|
|
|
|
}
|
|
|
|
|
|
|
|
would maintain binary compatibility. Obviously this would add a fair
|
|
|
|
bit of cruft if used extensively, but considering the changes between
|
|
|
|
minor versions would probably be worthwhile to avoid bumping library
|
|
|
|
major version. Naturally in the next major version print_stuff() would
|
|
|
|
assume the functionality and arguments of print_stuff2().
