similar to: replicating a compacted database

The Xapian documentation talks about a situation where you don't want to do two database swaps while in the process of replicating. It says... To confuse the replication system, the following needs to happen: 1. Start with two databases, A and B. 2. Start a replication of database A. 3. While the replication is in progress, swap B in place of A (ie, by moving the files around, such that B

I've written a little Xapian tutorial using Python that indexes tweets. It's hopefully useful to anybody trying to figure out how it all works in Python (actually, how it all works in general). Please let me know if I've made any mistakes, and comments are always welcome. http://www.s7labs.com/learn/xaptut/ Wes -- http://www.s7labs.com

Hi I have within a quite big function foo1, an internal function foo2. Now, in order to have a cleaner code, I wish to have the internal foo2 as "external". This foo2 was using arguments within the foo1 environment that were not declared as inputs of foo2, which works as long as foo2 is within foo1, but not anymore if foo2 is external, as is the case now. Now, I could add all those

please see the code below. foo2 fails to dispatch correctly, but foo does fine. i have tried 'cacheMetaData(1)' and a number of different variants of 'cacheGenericsMetaData', on the possibility there is a caching issue. but i still can't sort it out. also one general question: does it really matter what's in the body of the function definition in a

All, I want to run automated unit tests as part of my build. I am building to my test environment. Upon successful completion of all of my unit tests, I would then like to load some data (using a fixture, I imagine) into my test database that will act as fresh "system test" data for my users to play with. What is the best way to "load the standard system test/user acceptance

Is there a mechanism or technique to allow me to boost document relevancy, independent of search terms? I do not necessarily want to do any of the sorts described here: http://xapian.org/docs/sorting.html#sorting-by-value. Rather I'd like to sort by something like relevancy*boost factor, like: http://lucene.apache.org/java/2_3_2/api/org/apache/lucene/document/Document.html#setBoost(float)

Hello! Say I have a function foo1, which has argument ... to pass various arguments to foo2 i.e. foo1 <- function(x, ...) { foo2(x, ...) } Say that foo2 accepts argument arg1 and I would like to do the following: - if foo1 is called as foo1(x) then I would like to assign some value to arg1 inside foo1 before calling foo2 arg1 <- "some value" foo2(x, arg1=arg1) - if foo1 is

Thank you very much for your useful suggestions. These are exactly what I was looking for. foo <- list(foo1, foo2, foo3) lapply(foo, function(x) matrix(unlist(x), nrow = length(x), byrow = TRUE)) or lapply(foo, function(x) do.call('rbind', x)) Best, Muhammad Subianto On 4/11/06, Muhammad Subianto <msubianto at gmail.com> wrote: > Dear all, > I have a result my experiment

Dear R-devel, I'm trying to validate the results from a C function, against a (trial and tested) older R function. For reasons unknown to me, the C function seems to give different result sometimes at each trial, even with the very same data. These are the relevant outputs from R: > library(QCA) Loading required package: lpSolve > benchmark <- function(x, y) { + index <- 0

Dear all, I have a result my experiment like this below (here my toy example): foo1 <- list() foo1[[1]] <- c(10, 20, 30) foo1[[2]] <- c(11, 21, 31) foo2 <- list() foo2[[1]] <- c(100, 200, 300) foo2[[2]] <- c(110, 210, 310) foo3 <- list() foo3[[1]] <- c(1000, 2000, 3000) foo3[[2]] <- c(1100, 2100, 3100) list(foo1,foo2,foo3) The result: > list(foo1,foo2,foo3) [[1]]

This is a recent R-devel. file.copy() is not vectorized if multiple destinations succeed: cat("foo1\n", file = "foo1") cat("foo2\n", file = "foo2") unlink(c("copy1", "copy2"), recursive = TRUE) file.copy(c("foo1", "foo2"), c("copy1", "copy2"), copy.date = TRUE) #> Error in

All, I have need of getting at some underlying database metadata for ActiveRecord descendants. Does anyone know if I can get access to the following attributes of the underlying column for a given ActiveRecord object: Is it a currency object? Is it nullable? Is it a signed int? Is it searchable? Column length Column name Column precision Column scale Column data type - how specific can I get

Hi, We've encountered a difference in running time between a straight function call and the same call using do.call when the called function generated an error. We've isolated the problem to the following small reproducible example: Consider the following function: foo <- function(nr = 2e6, nc=3, use.do.call = FALSE) { nn <- paste("V", 1:nc, sep="") z <-

Hi the list, I define a method that want to change an object without assignation (foo(x) and not x<-foo(x)) using deparse and assign. But when the argument of the method does not match *exactly* with the definition of the generic function, assign does not work... Anything wrong? Christophe #------ Does not work ------#

Hi all, For some reason, I would like to use functions bellow (see example code bellow), but instead I get the following error message: *Error in foo2(...) : unused argument(s) (arg3 = 3)* #--------------------- # example code #--------------------- foo1 <- function(arg1,...) { print(arg1) foo2(...) foo3(...) } foo2 <- function(arg2) { print(arg2) } foo3 <- function(arg3) {

I successfully used .Fortran to load and execute my fortran procedures under WinXP and 32 bit R. Alas, the same isn't true with my next Windows 7/64 machine, R 2.14.1 (64 bit) and the gnu gfortran (64) compiler (mingw64 v. 4.6.1). Though I'm able to compile the routines from the command line using gfortran '...', .Fortran('foo2') results in an error saying the Fortran

Dear List: In short, I am writing a number of functions as building blocks for other functions and have some questions about scoping and passing arguments. Suppose I have functions foo1, foo2, and foo3 such that: foo1<-function(a=1,b=TRUE,c=FALSE){#do stuff}; foo2<-function(x=1,y=FALSE,z=c(1,2,3,4)){#do stuff}; foo3<-function(lambda,...){lambda*foo1()*foo2()}; I want to be able to

Hi, although I've done S3 dispatching for more than a decade now, I think I managed to overlook/avoid the following pitfall when using NextMethod(): If you explicitly pass argument '...' to NextMethod(), you will effectively pass those argument twice to the "next" method! EXAMPLE: foo0 <- function(...) UseMethod("foo0"); foo1 <- function(...)

I guess that is a solution. :/ In another example in the 'disposables' package I have: \donttest{ pkg <- make_packages( foo1 = { f <- function() print("hello!") ; d <- 1:10 }, foo2 = { f
