...em: I can't figure out how to do (2) with the LLVM JIT. It is very important that the driver does not have access to any other function in the application except those I provide. It's not OK for our application to abort if a driver calls an undefined function - I want to just disable _that driver_ in that event. I can use DisableSymbolSearching() but that causes application to abort for unknown symbols. Please advice! /Marcus

Hello list. I would like to get your opinion on what is a safe multi-user environment. The scenario: We would like to offer to some customers of ours some sort of network backup/archive. They would put daily or weekly backups from their local machine on our server using rsync and SSH. Therefore, they all have a user account on our server. However, we must ensure that they would absolutely not be

Hi, I'm Marianna I'm trying to apply the command "repeat" to my matrix but the repeat process doesn't work as I would. In particular I would like to apply the function robustm () _that I have created_ to my two matrices, if the difference between the two matrices is less than 0.001, R give me back the last matrix. The code thus created allows me to repeat the process only on the first two matrices: function(x) { for(i in 1:10) repeat { b<-robustm(S_X) b2<-robustm(b) if(ab...

An LLVM program can call any address, valid or not. If the programmer figures out the address of one of those "forbidden" functions, he can call it. You ma...

...balance it later. Regards Saptarshi There was a follow up in a subsequent email Hello, However, I do need some sort of protection. (pseudo code) SEXP a = Rf_allocVector(STRSXP,....) protect a for i = 1 to length of vector SET_STRING_ELT(a,i, Rf_mkChar(...)) end unprotect a return a I _need _that protect because in the for loop i also call some R functions and need the object 'a' to be protected. However, as I pointed out, 1. I replaced protect by PreserveObject 2. remove the unprotect word I can guarantee, that some time later ReleaseObject will be called on 'a'. So ulti...

Here''s something that caused me a couple of hours of head-scratching today: Apparently, if your model doesn''t derive from ActiveRecord, it is NOT reloaded for each operation in the development environment. I was working with something that uses a single model per session, and stores its data in the session. I kept wondering why I didn''t see my changes. Finally, I

Hi there, System is FreeBSD 4.9 Stable Had a problem during a portupgrade that when portupgrade did some cleaning a directory could not be deleted because it were not empty. However, it was empty. rm -rf didn't help either. Because I didn't know what to do I decided to boot. At system startup fsck was started which produced the message: unexpected softupdate inconsistency and also that

Hi, I am helping with the effort to implement scalable vectors in the codebase in order to add support for generating SVE code in the Arm backend. I would like to propose a refactor of the Type class hierarchy in order to eliminate issues related to the misuse of SequentialType::getNumElements(). I would like to introduce a new class FixedVectorType that inherits from
