[Bioc-devel] rfaRm package
Dear all, My rfaRm package has been giving TIMEOUT in the build results on all plaforms recently. I have been tried to debug the issue, but I am unable to reproduce the problem locally. The build report only seems to indicate that it times out while building vignettes (http://bioconductor.org/checkResults/release/bioc-LATEST/rfaRm/merida1-buildsrc.html). Would there be any way to specifically find out at which point of building the vignette the timing out is taking place? Thanks a lot in advance!

Re: [Bioc-devel] Time-out error on Ubuntu 20.04 build
Hi Hervé, Thanks a lot for looking with detail into this. I completely agree that a fix for this would be very beneficial. I pushed yesterday an update to the devel version of ncRNAtools, which hopefully should fix the issue. The change seems not to be propagated yet, but hopefully it will be reflected in the build report soon!

And for some reason this firewall causes the internal calls to httr::GET() to return responses with the following header: > GET(redirectURL)$headers $date [1] "Tue, 04 May 2021 01:59:02 GMT" $server [1] "Apacheadding: CentroidFold/ (stored 0%), CentroidFold/base-pairing-prob.txt (deflated 58%), CentroidFold/structure.eps (deflated 58%), CentroidFold/base-pairing-prob.png (deflated 18%), CentroidFold/base-pairing-prob.pdf (deflated 10%), CentroidFold/structure.pdf (deflated 19%), CentroidFold/structure.txt (deflated 25%), CentroidFold/base-pairing-prob.eps (deflated 60%), CentroidFold/structure.png (deflated 13%)" $`transfer-encoding` [1] "chunked" $`content-type` [1] "text/html; charset=UTF-8" $via [1] "1.1 phswsa8.partners.org:80 (Cisco-WSA/12.5.1-035)" $connection [1] "keep-alive" attr(,"class") [1] "insensitive" "list" Two things about this header: 1) The "via" field indicates the presence of the firewall. 2) There's no " adding" field. My understanding is that ncRNAtools:::checkSecondaryStructureQuery() expects to see that field as an indication that the initial query is no longer running. Note that the initial query here is no longer running and the final results are present in the header. However, instead of showing up in the " adding" field, they've been merged to the "server" field! For comparison here is what a clean header looks like on my laptop or on other build machines: > GET(redirectURL)$headers $date [1] "Tue, 04 May 2021 02:13:18 GMT" $server [1] "Apache" $` adding` [1] "CentroidFold/ (stored 0%), CentroidFold/base-pairing-prob.txt (deflated 58%), CentroidFold/structure.eps (deflated 58%), CentroidFold/base-pairing-prob.png (deflated 18%), CentroidFold/base-pairing-prob.pdf (deflated 10%), CentroidFold/structure.pdf (deflated 19%), CentroidFold/structure.txt (deflated 25%), CentroidFold/base-pairing-prob.eps (deflated 60%), CentroidFold/structure.png (deflated 13%)" $connection [1] "close" $`transfer-encoding` [1] "chunked" $`content-type` [1] "text/html; charset=UTF-8" attr(,"class") [1] "insensitive" "list" Unfortunately I don't have any control on how the firewall at DFCI is configured so I'm asking if you would be willing to modify ncRNAtools to accommodate this situation. Note that the benefit of doing this is that it will also solve the issue for people in other institutions that have a firewall configured in a way similar to the DFCI's firewall. Hope this makes sense. Best regards, H.

Re: [Bioc-devel] Time-out error on Ubuntu 20.04 build
Dear All, Since it seems the main Linux target in 3.13 is now Ubuntu 20.04, I have been recently trying to get back to fixing the TIMEOUT of my package ncRNAtools. Mike previously reported as seen below that he does not get the TIMEOUT when running R CMD build / check on an Ubuntu 20.04. I have also tried to reproduce the error on an Ubuntu 20.04, and could not manage to do so. I am unsure what to do at this stage in order to trouble shoot the problem. Does anybody have any suggestions about to go around this?

It took a couple of minutes. Rolling back to an older version prior to the SSL patch would lead to failure and the original error.

Apparently. I didn't try Mike Smith's suggested workaround myself so I don't know for sure.

[Bioc-devel] ncRNAtools not available for R 4.1.0
Dear all, I have recently been notified of errors during the build of ncRNAtools in the devel branch. Since the errors are not showing up in release, I tried to set up a correct devel environment to check the problems. I first downloaded R 4.1.0 from https://mac.r-project.org I then set up BioC 3.13 with the following: if (!requireNamespace("BiocManager", quietly=TRUE)) install.packages("BiocManager") BiocManager::install(version = "devel") I then checked if the environment was valid with BiocManager::valid() which returned TRUE. However, when attempting to install ncRNAtools, I got the following: > BiocManager::install("ncRNAtools") 'getOption("repos")' replaces Bioconductor standard repositories, see '?repositories' for details replacement repositories: CRAN: https://cran.rstudio.com/ Bioconductor version 3.13 (BiocManager 1.30.12), R 4.1.0 alpha (2021-04-29 r80247) Installing package(s) 'ncRNAtools' Warning message: package �ncRNAtools� is not available for this version of R A version of this package for your version of R might be available elsewhere, see the ideas at https://cran.r-project.org/doc/manuals/r-patched/R-admin.html#Installing-packages Does anybody have any advice on how to proceed to manage to install ncRNAtools in a valid Bioc devel environment?

Re: [Bioc-devel] Time-out error on Ubuntu 20.04 build
Hi Hervé, Thanks a lot for your reply and clarification. It is reassuring to know that Ubuntu 18.04 is still the primary Linux target! I am not running Ubuntu 20.04 on a Docker image, but I am running it on a virtual machine (VirtualBox) on RedHat 7. Do you think this could be a similar case as for the Docker image? Interestingly, my other package on Bioconductor rfaRm had the same issue related to SSL on Ubuntu 20.04. I was able to solve it by using the same workaround, and am now getting OK on R CMD install, build and check on nebbiolo1 (http://bioconductor.org/checkResults/devel/bioc-LATEST/rfaRm/ ). This seems to indicate that the same workaround has different effects depending on the URL being accessed possibly? Interestingly, the workaround has at least led to a TIMEOUT in the case of ncRNAtools, and not an ERROR, as was previously the case. The TIMEOUT seems to happen when creating the vignettes. Is it safe to assume then than knitting the vignette under the same environment should also get stuck at some endless/very long step? I will try to see if I can get access to a native Ubuntu 20.04 environment, to try knitting the vignette with different code chunks removed. Maybe we can figure out some additional extra setting to pass to config() for the specific URL that is leading to the TIMEOUT, that will provide a temporary workaround.

I can reproduce the error by running 'R CMD build ncRNAtools' interactively on nebbiolo1. Yes it seems that the timeout is related to the SSL issue on Ubuntu 20.04. Are you running Ubuntu 20.04 on a Docker image? I've read somewhere recently that some HTTPS/HTTP access issues on Ubuntu 20.04 are not always reproducible on a Docker image. I see in the 'git log' that yesterday you've reverted back your recent changes and that you are now using HTTPS again together with the following workaround: https://github.com/Ensembl/ensembl-rest/issues/427#issuecomment-702044967 Unfortunately it didn't seem to work (we still see the TIMEOUT on today's report). Thanks for trying this anyway. At this point I don't have a good suggestion, unfortunately. Note that malbec1 (Ubuntu 18.04) is still our primary Linux builder and propagation is still decided on whether or not a package passes BUILD and CHECK there. So the TIMEOUT on nebbiolo1 won't have any practical consequences as far as the next release is concerned. At some point, we really want to make Ubuntu 20.04 our primary Linux target, and get rid of the Ubuntu 18.04 builder. But we won't do this before we have a good solution for the current SSL issue on Ubuntu 20.04. Best, H.
