How to update RCurl and curl to the version on the host machine?



Initially I was trying to use devtools::install_github("EdwinTh/padr") where I got the following error:


devtools::install_github("EdwinTh/padr")



Error in curl::new_handle() : An unknown option was passed in to libcurl


Error in curl::new_handle() : An unknown option was passed in to libcurl



After some time I found out that devtools uses curl/RCurl which wraps the current version of curlon the host machine.


devtools


curl/RCurl


curl



The host(Ubuntu 14.04.5 LTS) machine version of curl is:


curl



1$ curl -V
curl 7.61.0 (x86_64-pc-linux-gnu) libcurl/7.61.0 OpenSSL/1.0.1f zlib/1.2.8 libssh2/1.8.0 librtmp/2.3


1$ curl -V
curl 7.61.0 (x86_64-pc-linux-gnu) libcurl/7.61.0 OpenSSL/1.0.1f zlib/1.2.8 libssh2/1.8.0 librtmp/2.3



where curlis located in:


curl



12$ which curl
/usr/local/bin/curl


12$ which curl
/usr/local/bin/curl



and is working fine when using curl::new_handle()directly from the terminal


curl::new_handle()



In comparison the curl/RCurl version is:


curl/RCurl


> RCurl::curlVersion()
$age
[1] 3

$version
[1] "7.35.0"`



I'm assuming that this might be the underlying issue. My problem now is how to let Rs curl/RCurl point to the corresponding version.


curl/RCurl



I have tried everything I found so far on that topic for R like:


R



install.packages("RCurl", type="source") and
install.packages("curl", type="source")


install.packages("RCurl", type="source")


install.packages("curl", type="source")



as well as adjusting curlon the host machine:


curl


wget https://libssh2.org/download/libssh2-1.8.0.tar.gz
tar zxvf llibssh2-1.8.0.tar.gz
cd libssh2-1.8.0
./configure
make
sudo make install

wget http://curl.haxx.se/download/curl-7.61.0.tar.gz
tar zxvf curl-7.61.0.tar.bz2
cd curl-7.61.0
./configure --with-libssh2=/usr/local
make
sudo make install



But I always get the same version for curl/RCurl 7.35.0 instead of 7.61.0.


curl/RCurl



Appreciate any insights!





For starters, you could consider not being on a four-year old release of your distro. With Ubuntu 18.04 you have no such problem. But in short: update the libcurl*-dev package (complications: there are several) and the reinstall RCurl and/or curl.

libcurl*-dev


RCurl


curl





Hi @DirkEddelbuettel there are some restrictions hindering to upgrade Ubuntu. But anyway, thanks for taking time to give your opinion. libcurl*-dev was already installed. So basically I removed it and reinstalled sudo apt-get install libcurl4-openssl-dev as well as those two packages without any change in the behaviour.

libcurl*-dev


sudo apt-get install libcurl4-openssl-dev





If you tell Ubuntu to install from 14.04 it will of install the same package over and over. That is what sticking with a release means. Your problem, in essence, is to figure out where to get a newer curl library built for that release from. And/or how to tell the R packages how to prefer the local one.

Hystrix command on request collapser fallback

Clash Royale CLAN TAG #URR8PPP Hystrix command on request collapser fallback I have a scenario where I want to apply hystrix on the fallback (and process one-by-one) of a hystrix request collapser's batch method. The fallback method ( processEntryBatch_fallback ) is invoked. But the hystrix command ( processEntryBackup ) in turn the fallback invokes is not reported (doesn't even appear on dashboard). And the fallback method ( finalFallback ) is not invoked either. I would like to know what am I missing here ? I referred javanica documentation processEntryBatch_fallback processEntryBackup finalFallback @Service public class DummyService private static final Logger log = LoggerFactory.getLogger(DummyService.class); //batch processing method public void processEntry(List<String> msg) //batch processing throw new RuntimeException("Exception while batch processing"); //processing one-by-one @HystrixCommand(fallbackMethod="finalFallback") public ...
