This fixes the race conditions for me, using the test described here: https://www.redhat.com/archives/libguestfs/2017-September/msg00226.html Rich.

I found a core dump: term1$ nbdkit -fv --filter=xz null xz-max-depth=$((0x4000000000000000)) term1... term2$ qemu-nbd --list term1... nbdkit: debug: null: open readonly=1 nbdkit: error: calloc: Cannot allocate memory nbdkit: debug: xz: close Segmentation fault (core dumped) (Note that the use of --run or daemonizing nbdkit makes it a bit harder to see the core dump, but it is still happening.)

It's finally time to implement one of the TODO items: we want to support a thread pool of parallel readers from the client, in order to allow multiple in-flight operations with potential out-of-order completion. We also need at least one plugin that supports parallel processing for testing the option; the file plugin fits the bill. Add and document a new command line option, -t/--threads=N,

I am having a problem with any terms which contain hyphens in them. Is there a particular reason why this wouldn''t work? i''m using aaf, and have tried with the the previous version (pre 0.10.0) and the newest versions of both ferret and aaf. Basically, the problem is that term1-term2 is something my users want to search for, and it appears in the titles of publications,

Hello, I am interested in fitting a segmented model with unknown joint points in nls and perhaps eventually in nlme. I can fit this model in sas (see below, joint points to be estimated are a41 and a41), but am unsure how to specify this in the nlm function. I would really appreciate any suggestions or example code. Thanks a lot. -andy proc nlin data=Stems.Trees; params b41=-3 b42=1.5

Hi all, I am trying to construct a pairwise coocurrence matrix for certain terms appearing in a number of documents. For example I have the following table with binary values showing the presence or absence of a certain term in a document: term1 term2 term3 term4 term5 doc1 1 1 0 0 1 doc2 1 1 0 1 1 doc3 1 0 0 0 1 And I want to have a matrix with the number of the pairwise coocurrencies. So,

Dear list members, I want to draw surfaces of Dirichlet distributions with different parameter settings. My code is the following: #<begin code> a1 <- a2 <- a3 <- 2 #a2 <- .5 #a3 <- .5 x1 <- x2 <- seq(0.01, .99, by=.01) f <- function(x1, x2){ term1 <- gamma(a1+a2+a3)/(gamma(a1)*gamma(a2)*gamma(a3)) term2 <- x1^(a1-1)*x2^(a2-1)*(1-x1-x2)^(a3-1)

Dear Friends, I have been trying to learn how to use the derivative free optimization algorithms implemented in the package RGENOUD by Mebane and Sekhon. However, it does not seem to work for reasons best described as my total ignorance. If anybody has experience using this package, it would be really helpful if you can point out where I'm making a mistake. Thanks in advance Anup Sample

Hello! I have a problem with integrate() in my function nctspa(). Integrate produces an error message "evaluation of function gave a result of wrong length". I don't know what that means. Could anyone suggest me what is wrong with my function? These are the examples of function calls that work OK: nctspa(a=1:10,n=5) nctspa(a=1:10, n=5, mu=2, theta=3, renorm=0) This does not work:

DeaR UseRs, I have the following code (see below). It is working as expected although I have two problems/questions: - how can I set the size of the graph? It may sound silly, but I couldnt figure that out - is it possible to export this small "interactive aplication" to html or a latex document, or maybe pdf? Thank you for your attentions. Best wishes: Daniel the code:

Hi, I would really appreciate if I could get some help here. I'm using nlm to minimize my negative log likelihood function. What I did is as follows: My log likelihood function (it returns negative log likelihood) with 'gradient' attribute defined inside as follows: # ==========Method definition====================== logLikFunc3 <- function(sigma, object, totalTime) { y <-

Hi, all: I have wrote a demo patch for Backend for Lucene format indexes, Lucene version is 3.6.2. http://lucene.apache.org/core/3_6_2/fileformats.html Now, this demo patch just support the basic features in Lucene. Compound File(.cfs/.cfe)?term vector(.tvx/.tvd/.tvf) delete document(.del) are not supported, skip list in .fdx is not supported too example/quest.cc is used to test this demo.

Tested via: term1$ qemu-nbd -k $PWD/sock -t -f raw -x foo junk --trace=nbd_\* term2$ ./nbdkit -f -v -e bar nbd socket=$PWD/sock export=foo term3$ qemu-io -t none -f raw nbd://localhost:10809/bar --trace=nbd_\* and checking the traces to see that 'w 0 1' vs. 'w -f 0 1' was able to influence whether the FUA flag showed up at the server in term1. Still to go: figure out how to

I'm still working on the interleaving (and Rich reminded me on IRC that we still don't have THREAD_MODEL_PARALLEL working anywhere yet, anyways). Since nbdkit doesn't really have a parallel plugin yet, my testing on that front will have to use qemu-nbd as the original server, as well as qemu-io as the driver (qemu-io's aio_read and aio_write commands can be used to trigger
