R-helpers, When I use cURL in the Terminal: curl --cookie-jar cookie.txt --url "http://corpusdelespanol.org/x.asp" --user-agent "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:16.0) Gecko/20100101 Firefox/23.0" --location --include a cookie file "cookie.txt" is saved to my working directory. However, when I try what I think is the equivalent command R with RCurl:

Hello. I know that it's usually possible to write cookies to a cookie file by removing the curl handle and doing a gc() call. I can do this with getURL(), but I just can't obtain the same results with postForm(). If I use: curlHandle <- getCurlHandle(cookiefile=FILE, cookiejar=FILE) and then do: getURL(http://example.com/script.cgi, curl=curlHandle) rm(curlHandle) gc() it's

LGTM. I will commit. On Oct 10, 2012, at 1:20 PM, Shuxin Yang <shuxin.llvm at gmail.com> wrote: > Hi, > > The attached is the fix to radar://11663049.

I'd like to raise this again now that 4.4 is out. Below is a more complete patch which includes a function to properly cleanup libcurl when R quits. Implementing this is a little tricky because libcurl is a separate "module" in R, perhaps there is a better way, but this works: view: https://github.com/r-devel/r-svn/pull/166/files patch:

Hi, The attached is the fix to radar://11663049. The optimization can be outlined by following rules: (select (x != c), e, c) -> select (x != c), e, x), (select (x == c), c, e) -> select (x == c), x, e) where the <c> is an integer constant. The reason for this change is that : on x86, conditional-move-from-constant needs two instructions; however,

This patchset provides updates to the viewer in preperation for its fedora submission. Included are patches cmd-line parameterizing hostname/user/pass/vm, the addition of a man page, cleanup of the project's structure, and updates to the spec.

This is an RFC only, at the very least it lacks tests. This implements a rather complex new feature in nbdkit-curl-plugin allowing you to specify an external shell script that can be used to fetch an authorization token for services which requires a token or cookie for access, especially if that token must be renewed periodically. The motivation can be seen in the changes to the docs in patch 2.

Evolution of this patch series: https://www.redhat.com/archives/libguestfs/2020-July/thread.html#00073 Instead of auth-script, this implements header-script and cookie-script. It can be used for similar purposes but the implementation is somewhat saner. Rich.
