llvm-ir: TBAA and struct copies
Hi Ivan,
The code that we have is indeed different from what the 'standard llvm' expects. Let me explain:
in our version we came into this situation in two steps:
1) I added support for 'special types' that map directly to types supported by hardware.
These types are represented by a struct containing a single iXXX member, providing the necessary bits
of the type, and at the

[llvm-lit] Is it possible to write a test for Linux only?
Thanks Jon. Actually I tried “x86_64-linux”, but it makes the test “Unsupported” from my linux machine, and it was because my test is under clang, not llvm. It seems that clang doesn’t support “x86_64-linux” yet. Thanks again!
Best,

It is $target dependent. I’m curious what makes you think it is $host dependent.

llvm-ir: TBAA and struct copies
Hi,
I have a question about the current definition of TBAA (See [1]).
In the LLVM-IR code that we produce, we generate load/stores of struct types. (See [2] and [3] for a godbolt example showing the issue)
For following c-alike code:
struct S { int dummy; short e, f; } x,y;
struct S* p = &x;
int foobar() {
x.f=42;
*p=y; //**** struct copy
return x.f;
}
We produce:

[llvm-lit] Is it possible to write a test for Linux only?
Hello,
I wonder if I can write a test that runs only on Linux. I was thinking of adding “REQUIRES” to the test, but couldn’t find a feature name for Linux (if one exists). Thanks!
Best,
Taewook

rounding change
This is a small heads up for package maintainers.?? Under the more recent R-devel, R CMD
check turned up some changes in the *.out files.?? The simple demonstration is to type?
"round(51/80, 3)", which gives .638 under the old and .637 under the new.?? (One of my
coxph test cases has a concordance of exactly 51/80).
In this particular case 51/80 is exactly .63750000, but that value

Dovecot: Mails flagged as read get flagged as unread
Hi all
We experience some unexpected behavior with dovecot. It happens that
emails marked as read get marked as unread (MUA is Thunderbird on port
143). Unfortunately this happens randomly, reproducing this issue is
difficult. We could not find any pattern, it happens rarely.
We are running dovecot version 2.2.24 on Debian Jessie (backports
repository).

calling R API functions after engine shutdown
Hi!
We?ve recently come across an example where a package (minqa) creates an Rcpp Function object in a static variable.
This causes R_ReleaseObject to be called by the destructor at a very late point in time - as part of the system exit function:
static Function cf("c");
I?m wondering if that is considered to be ?safe??
Is the R engine supposed to stay in a state where calls to API

Winbind issue after upgrading from 4.7.5 to 4.8.3
Hi guys
We recently upgraded our Samba clusters from 4.7.5 to 4.8.3 and noticed
a difference in behavior for winbind.
The situation is as follows
Assume we have a local Linux user XYZ (UID 519) as well as a AD user
object XYZ (UID 30001).
idmap config * : backend = tdb2
idmap config * : range = 30000-50000
In our share definitions we regularly use the "force user"

Dear Martin,
What's the ETA for _R_CLASS_MATRIX_ARRAY_=TRUE to become the new

looking for one-liner for strsplit and regex
Hi,
I have a line such as:
myline <- " 0.100000 1.5000 0.6000 538
0.369404"
and I would like to put the numbers into a vector. Some combination of
tabs and spaces occur between the numbers.
I tried:
try1 <- strsplit(myline,"[[:blank:]]+")
> try1
[[1]]
[1] "" "0.100000" "1.5000"

seg fault with strsplit (PR#158)

strsplit (PR#424)
In R.99, when you strsplit with a space (split=" ") as separator and
the string contains two consecutive spaces, "" is returned.
strsplit(" "," ")
returns
[[1]]
[1] "" ""
whereas it used to return character(0)
Is this really useful like this?? It certainly messes all my code up. Jim
