[Bioc-devel] tokay2 internet connectivity

[Obenchain, Valerie]

Just to close the loop on this - the conversation went off-line and was resolved. When the omabrowser server OS was changed from Ubuntu to CentOS the problems on the Windows builders went away.

Hi Klara,

Unfortunately I still don't have an solution for this. For some reason, Internet Explorer on our Windows build machines cannot access the https://omabrowser.org/ web site. The problem can be reproduced independent of your package simply by opening IE and trying to access the site - this returns a 'page cannot be displayed' error.

I've looked extensively into the settings for IE, cipher suites and any known security issues. None of these has led to a solution. I don't have a problem accessing other web sites from IE on the Windows builders. However, I also don't have a problem accessing omabrowser.org from other browsers or other combinations of Windows/IE. The problem appears to be unique to the combination of the omabrowser.org site and some setting in Windows Server 2012R/ IE 11 on the builders.

If anyone in the community has experienced a similar problem with IE I'd welcome help troubleshooting - feel free to contact me off-list at valerie.obenchain using roswellpark.org<mailto:valerie.obenchain using roswellpark.org>.

I've contacted the OMA browser people to ask if anything has changed with their web interface in the recent months. For the time being please ignore the Windows error for OmaDB.

Thanks.
Valerie

Thanks for your patience on this. I belive it's related to the Internet Explorer settings on the builders. Hope to have this resolved soon.

Hi Bioc team,

I am one of the maintainers for the OmaDB package, now in 3.7 release. The package is passing build and check on both mac and linux, however I am still experiencing an error on windows (tokay2) which I reported earlier and was suggested it might be due to connectivity problems by Martin. We have increased the robustness of the error handling in the package since (more useful error message, sending the request again 3 times at increasing intervals if it does fail etc) which has shown that the error is indeed due to transient internet connection of the server.

To alleviate this in the vignettes, instead of sending requests to the API I have included some lightweight example objects with the package. However, the error still occurs in tests and some function examples. As the package is an API wrapper and so internet connection dependant, I am not sure what is the best way to address this error. Would you kindly be able to provide some guidance on this?

Many thanks in advance,

Klara
