...d Cox models, the C code needs to get the value of the penalty and the penalty is an arbitrary S expression passed down from top level. Terry T ---------------------------- In survival_2.36-12 (and earlier), in the function cox_callback() at cox_Rcallback.c:40: PROTECT(coxlist=eval(lang2(fexpr,data),rho)); the return value of the call to lang2() is vulnerable if allocations within eval() give rise to garbage collection. (Discovered during CXXR development.) Andrew

I knowf R functions ca be called passing some parameters. My first question is: how are parameters passed to R functions ? Browsing through R archives I found an answer confirming taht parameters can be passed to the called function by value. I wonder whether passing the parameter address is possible somehow to allow the function to actually change its value. My second question is about

The following series of patches fill in most of the gaps in the OCaml bindings to libxl, to make them useful for clients such as xapi/xenopsd (from XCP). There are a number of bugfixes to the existing bindings as well. I have an experimental version of xenopsd that successfully uses the new bindings. An earlier version of the first half of the series was submitted to the last by Ian Campbell on

The following series implements libxl_domain_config_init as per the libxl API requirement that each type has an init function. The first function does this in an open coded manner and is proposed for Xen 4.2. The second function is RFC only since it moves the definition of this type into the IDL and makes the required infrastructure updates to enable this. I think this is more 4.3 material at

Hello, Third version of the NUMA placement series Xen 4.2. All the comments received during v2''s review have been addressed (more details in single changelogs). The most notable changes are the following: - the libxl_cpumap --> libxl_bitmap renaming has been rebased on top of the recent patches that allows us to allocate bitmaps of different sizes; - the heuristics for deciding
