[Opensim-dev] My new LSL compiler project

Mon Nov 9 21:36:59 UTC 2015

Blake,

I found the LSL language test on the wiki when I first started working on
the library,
I forgot where I got them and went looking for the other ones but could not
find them again.

These in particular:

http://wiki.secondlife.com/wiki/LSL_Language_Test
http://wiki.secondlife.com/wiki/LSL_Language_Test_2

There are a few current failures in the first test:

The first is due to quaternion division producing different (but valid)
results in OpenSim on line 436
The second is on line 471-473 and it is caused by an overflow exception
being thrown
The third is on line 480-482 and it is also caused by an overflow exception.

The rest of the failures are caused by the Float equality delta tests, and
comparing vectors/rotations cast to strings. (their formatting is slightly
different in opensim)

There are several in the second, due to vectors and rotations in OpenSims
runtime converting into strings with spaces after the commas.
In secondlife there are no spaces in the list of components that make up a
vector or rotation when its ToString()'d

And an instance of:  [1] != [2,3] (1 expected -1), on line 224 of
LSL_Language_Test_2 which is a runtime related thing I am curious to
investigate.

I am unsure if I should improve the actual runtime types, or fix
differences generating workaround code.

I am inclined to believe that the quaternion runtime type should probably
not be messed with besides fixing the ToString() formatting,
I am not sure what opinions there are on modifying the other existing types.

==

All benchmark scripts on the page work and produce identical output to
second life.

LSL_Library_Call_Test_1 failed due to OpenSim using void for the return
type of llGiveMoney();, and also due to erroneous function parameters in
the script causing exceptions.

LSL_Library_Call_Test_2 compiles and fails due to erroneous parameters to
LSL functions causing exceptions, which halt the script.

Event_test_script fails due an issue with the order in which events are
called by OpenSim (I'm not exactly sure why).
