As per http://msdn.microsoft.com/en-us/library/system.random%28v=vs.100%29.aspx, the .NET Random class is not thread-safe.
If called by multiple threads at once, methods may return 0.
Except for llRand(), other OpenSimulator code did not lock before calling a shared Random instance.
This commit adds a ThreadSafeRandom class that extends Random but does internal locking so that it is thread-safe.
This change is invisible to existing callers and the explicit locking in the llFrand() implementation is now redundant.

CheckOrCreateScriptsDirectory()) when checking that scripts directory exists on compile.
Code was identical apart from error logging, but if there are failures creating these directories then you'll be
seeing lots of errors anyway, and these will be more informative

If the C# column can't be found in the positionMap (but the line can),
use the map immediately after it while correcting for the offset,
unless that results in an LSL position before the previous LSL position
in the positionMap.
The idea behind this heuristic is that in most, if not all cases C#
consumes more characters than LSL (for example LSL_Types.LSLInteger
instead of just 'integer').
Thus if the distance between the columns of two markers differ in
the C# and LSL file, the distance in the C# file will be larger.
Moreover, we can assume that every time this happens we will have
a marker at the beginning of the longer 'keyword', because those
keywords were generated by us in the first place.
For example:
C#: LSL_Types.LSLInteger f2(LSL_Types.LSLString s)
^ ^
1 2
will always have markers at the beginning of the long keywords
'LSL_Types.LSLInteger' and 'LSL_Types.LSLString'.
If an error is generated in between (for example at the beginning
of the function name 'f2') then the correct position is found
by using an offset relative to 2 rather than 1.
Note that a case where this isn't working correctly is
when the user adds extra spaces. For example:
LSL: integer f2( string s)
would still use the start of 'string' as reference and
then go backwards 3 characters only because the corresponding
C# still looks like
C#: LSL_Types.LSLInteger f2(LSL_Types.LSLString s)
^ ^
only 3 chars difference
and the reported error at 'f2' would be here:
LSL: integer f2( string s)
^
This can only be fixed by generating a mapping for 'f2' itself, or
generating a mapping whenever the amount of spaces is changed.

When a compile error reports a colum/error that is not an exact
match in the positionMap dictionary, the last position in the
map with a line number and position before the reported error
should be returned.
The old code had the following problems:
1) It returns l,c - which are line and column of the C# file, not LSL.
2) It doesn't set l to 'line' when the map has an entry with 'line'.
3) It sorts the map without taking columns into account, which may
result in a random order of the columns. With my mono implementation
the columns were reversed in order.
For example, if the map contains the following lines:
99,5,49,10
100,30,50,10
100,40,1,0
101,5,51,10
and a translation of 100,35 was requested,
then the old code would compare '100' with the keys in
the first column - setting l to that key while it is
smaller. Hence, l is set to 99.
Then it finds the key 100 and doesn't update l.
Because of the reversed sort order, it first compares
the column 35 with 40, finding that it is smaller
and therefore it stops; returning 99,1 instead of finding
the correct 100,30 entry and returning 50,10.
This patch causes 50,10 to be returned.
The remaining problems after this patch are:
1) The sorting might not be necessary at all.
2) The is code duplication (I fixed both instances,
but really there should be no code duplication
imho).

position map and leading to invalid error line numbers/columns
This is because jump statement generation was mistakenly inserting its own line without updating the csharp positions in CSCodeGenerator.
This is Aleric Inglewood's patch in http://opensimulator.org/mantis/view.php?id=7195 but applied to opensim itself rather than the defunct code generation in opensim-libs. Thanks!
This patch also adds a regression test for this case from myself.

This hasn't been mainntained since 2008 and has not been kept up with the rest of the language infrastructure.
Hence, it almost certainly doesn't work and has never been used, afaik
If this is wrong, please say on the opensim-users/dev mailing list.
Removing to reduce maintenance burden (since it still needs to be made to compile).

PERMISSION_CHANGE_LINKS
As per http://wiki.secondlife.com/wiki/LlBreakAllLinks
Same as existing llCreateLink() and llBreakLink()
|
| |
|
|
|
|
|
| |
These are identical to llCreateLink() and llBreakLink() except that they don't require script permissions.
However, osForceCreateLink() still requires that linked and linkee still have the same owner.
There's also an AutomaticLinkPermission setting in [XEngine] that could be set to true to prevent the LSL function checks.
But this doesn't allow the finer control over which users/scripts, etc. can do this that the OSSL functions provide.
