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

[Hong Ooi]

They are scanned probably because R CMD build does something like cp * to copy everything to a temp folder first up, before processing it. An argument could be made that it should manually loop through all files and dirs, checking each against .Rbuildignore before copying.

THANKS - you solved my question without me having to answer it. As I am using a makefile to build the package, I can easily rename the ignored directories before calling build.

But the question is why are these ignored directories scanned before building the package? They should be ignored anyway?

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%7C7962d328eb984556a2e708d7aecdc0db%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637170071036915332&sdata=cmY0VPEiEgcuhI%2B4wIT8iIimQhq7751IJ0KHdsPaMtg%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?
