Actually, cancel that: it finished successfully, but took 3 minutes to prepare the package:

r$> devtools::build()
v  checking for file 'C:\Users\hongo\Documents\GitHub\AzureStor/DESCRIPTION'        
-  preparing 'AzureStor': (3m 4s)
v  checking DESCRIPTION meta-information ...
-  installing the package to build vignettes
v  creating vignettes (6.5s)
-  checking for LF line-endings in source and make files and shell scripts (13.8s)  
-  checking for empty or unneeded directories
-  building 'AzureStor_3.1.0.9000.tar.gz'

This is really weird, I'm used to the package prep step taking 10 seconds at most.

Subject: [EXTERNAL] [R-pkg-devel] R CMD build hanging for some but not all packages

This is with R 3.6.2 on Windows 10 Pro 1909.

In the last couple of weeks, devtools::build() and devtools::check() have started hanging on some, but not all, of my packages. After some poking around, I discovered that it's actually R CMD build that is having problems, right after the "checking for file 'DESCRIPTION'" step.

A reproducible example can be found by cloning my AzureStor package: https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2FAzure%2FAzureStor&data=02%7C01%7Chongooi%40microsoft.com%7Cae76a58d39b64b491a1008d7ae4955a9%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637169502304943506&sdata=RW3TQM2D%2F3X43oGhiywDyKd%2F4oo5hFkOoVwZTUe9cOw%3D&reserved=0 If you run "R CMD build ." in the package directory, it should hang. This is a relatively simple package that doesn't require compilation, although it does import some commonly-used packages like httr, curl, jsonlite and xml2.

As far as I can tell, R on Ubuntu works fine. What's going on?
