R's dyn.unload() will unconditionally unload the given shared object; it does not check whether there is any object (external pointer or weak reference) with a C finalizer pointing into the space of the shared object being unloaded. So it is expected that R will segfault later when such finalizer is run. Currently there is no other way than to handle this on the side of the shared

Hi all, I'm not sure if I'm not supposed to do the following (the dyn.unload part, I mean) or this could be a bug (in R or Rcpp): ``` Rcpp::sourceCpp(code=' #include <Rcpp.h> class Object {}; //[[Rcpp::export]] SEXP new_object() { return Rcpp::XPtr<Object>(new Object()); }' ) new_object() dyn.unload(list.files(tempdir(), ".(so|dll)$",

Why do you say that / what did you have in mind? We say it because it is true. Rcpp registers C finalizers and running them after unloading will segfault. For now it would be better for

Hi I?aki, I think that "still reachable" memory is potentially a problem only if you cared about (frequent) package unloading, and if package unloading did not have correctness problems in the first place. I would only worry about "memory leaks" reported by valgrind. That your example (unloading a library while there is still an object with a finalizer implemented in that

Recall that we do not alter SEXPs or introduce additional additional reference counters -- because we do not think that altering the basic R API for such calls would be a wise strategy. So we do more or less what

Thanks, Tomas, Luke, for the clarifications. Then, I have another question. But first, let me introduce how I ended up here, because obviously I just don't go around dyn.unloading things that I've just compiled. I was testing a package with valgrind. Everything ok, no leaks. Great. But I'm always suspicious (probably unjustifiably) of all the memory that is reported as "still

hi, I have been attempting to run this script and am getting some strange results. The script connects to a database and retrieves a series of tables, using sequential sql statements. I have tested all of the sql statements in the PostGreSQL terminal and they all return the desired results. I place each table into a list and run a FOR loop for 'i' in the list. The script generates

I have a set of data that includes various data columns. One if the survival time and another if a continuous variable of ages. I want to put the ages into intervals so that I can then perform the Kalpan Meier test. I am trying to use the following code to build a column with the age group numbers in agecatagory<-c( ) for (i in 1:137) { { if(age[i]<=46) {agecat[i]<-1} if(age[i]>46

Hi Everyone, At the end of this email is a transcript of a problem I have found in RODBC version 2.3-1. It appears that the bug fix in odbcClose for the memory leak has meant that the garbage collector is falling over when it tries to free up the extPtr attribute of the RODBC connection pointer. Any advice on how to fix this? Thanks for your help, Tom

Any hope of KMail (and Kontact) coming to CentOS-7? What exactly is the problem? KMail seems to work on other Linux OS's. -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Hi, I have a small call center with 4 Zap lines and 4 agents. Agents login using sip phones with AgentCallbackLogin. I occasionally gets a complaint that when customers call the call center, after the initial greeting is over the call gets cut after playing the thank you message. I started investigating and found that that happens when the call gets transferred to an agent who is making an

Hi, I am changing from proprietary nvidia drivers to Nouveau drivers in my mediacenter. I run a Gentoo linux in this hardware and I am facing an out of signal screen just after the boot (when the nouveau module is loaded). If I blacklist this module and modprobe it in the prompt, the screen gets out of signal in my 1080p TV in this moment. I tried recompile the kernel enabling and disabling a

Hi, I have a question. I have dovecot 2.0.9 running on a CentOS 6.6 email server for a small department, ~15 users. amavis and postfix are also enabled. It appears that amavis invokes spamassassin, which tags incoming spam email. All email is then put into users local inbox directory, regardless of spam tag X-Spam_Flag value of YES or NO. I want instead to redirect spam to a special directory.
