Greetings everyone, I have a problem which I believe is a collision between the --ignore-existing option and filter rules. It appears to me that regardless of argument order, when I specify the two on a command line, even if a non-existing directory appears in the filter list as a protect rule. But when I change protect rules to exclude rules, the excluded files/directories appear not to be transferred. Now, for details... I have a sandbox which is a build of a complete OS image. I want to push the contents of this sandbox to both new and existing hosts, protecting some files wh...

Hi, Im currently trying to debug a 'error in unprotect: stack imbalance' problem and I am curious about two basic questions on the use of PROTECT and UNPROTECT, which I could not figure out: - which objects have to be protected, namely, if the code is something like: SEXP fun, e; /* get the expression e ... */ fun = eval(e, R_GlobalEnv); /* or...

I just got this error: > library(igraph) > comp <- decompose.graph(gr) Error: protect(): protection stack overflow Error: protect(): protection stack overflow > what can I do? the digraph is, indeed, large (300,000 vertexes), but there are very many very small components (which I would rather not discard). PS. the doc for decompose.graph does not say which mode is the default....

Hi, I have an SEXP obj in a C function called via .Call(). The obj is protected (in fact it is an argument to .Call and therefore automatically protected). If I set an attribute of obj does the attribute become protected too? Here is an example SEXP foo(SEXP obj) { SET_NAMES(obj, NEW_CHARACTER(3)); /* are names protected or not? */ ... } Thanks, Vadim [[alternat...

Apologies first, because I need to ramp up on Ruby and coding Ruby in Rails, however it''s my 3rd day with this beast :) so I''m asking : When I added protected methods to the model before it was like: protected method.................... end Would this be a valid way to write a protected method as well ?: attr_protected :column1, :column2 Perhaps this particular call is already protected inherent to the call, yet do I need to surround it with...

I received the following note this AM. The problem is, I'm not quite sure how to fix it. Can one use PROTECT(coxlist(eval(PROTECT.... , do I create an intermediate variable, or otherwise? I'm willing to update the code if someone will give me a pointer to the right documentation. This particular chunk was written when there was a lot of change going on in the callback mechanism and so there might...

...c(20L, 30L)) and return list(c(5L, 6L), c(7L, 10L), c(11L, 19L), c(20L, 30L)). Because the output is of variable length, I use a pairlist (because it is growable) and then I call Rf_PairToVectorList() at the end to make it into a regular list. I'm getting a strange garbage collection error. My PROTECTed pairlist prlst gets garbage collected away and causes a memory leak error when I try to access it. Here's my code. #include <Rinternals.h> SEXP C_int_mat_nth_row_nrnc(int *int_mat_int, int nr, int nc, int n) { SEXP out = PROTECT(Rf_allocVector(INTSXP, nc)); int *out_int = INTEGE...

I have a few simple questions about the usage of PROTECT, more specifically how careful one needs to be. Simple yes/no answers are fine. Most of the uses I have seen do protection when memory is allocated. But what if one just want to assign a value of another function to a variable. Say eg. that foo is a function that returns a SEXP. Would th...

I'm following the instructions on this URL http://wiki.centos.org/HowTos/RT_3.4.x_On_CentOS_4.x and came across the part that said "WARNING: RT overwrites some packages from the base distribution, especially mod_perl" How exactly do I "protect" the RT repository? It links to the "ProtectBase" program http://wiki.centos.org/PackageManagement/Yum/ProtectBase ...but what do I mod to protect this RT repository?

...about my code that was taking longer and longer to process. After following your suggestions, and I now thinking that the problem was some calls to Rf_duplicate in my C code. So I'm hoping I could get some clarification on what Rf_duplicate actually does. What is the real difference between PROTECT(y=x); and PROTECT (y = duplicate(x)); ? I do use duplicate on the list objects that are passed directly from R, since in the passed, I got some odd results of the original lists being changed (when I didn't want them to be). So suppose that x is the list that is passed from R to the C code....

...t was interfaced with R (R calls a library that takes SEXPs and converts the data frames into the internal structures of data), and I notice that for small data.frames the vectors don't get corrupt (n<200-ish). When I pass in larger data.frames, the vectors will become corrupt. I've been PROTECTING the heck out of everything (as best as I can from the examples) to make sure that something is not overlooked. I know the code in my library works fine becuase when I attempt to do the same thing (with much larger data arrays) none of this behaviour occurs. An example of the corruption is,...

Hi, Is it not ok to use both plugins at the same time? I have read from the wiki page of centos that you must use only either protect base or priorities plugin. I have been using the the config file below for months and did not encounter any problems. I used priority=1 and protect=1 on base and updates (addons,extras protect=1 ; set no priorities) for the CentOS-Base repo and on the rpmforge repo I used protect=0 and did not set...
