[R-pkg-team] Bug#903819: r-cran-rmarkdown: Broken link /usr/lib/R/site-library/rmarkdown/rmd/h/bootstrap-3.3.5/shim

[Ralf Stubner]

Package: r-cran-rmarkdown
Version: 1.10+dfsg-2
Severity: normal

Dear Maintainer,

I called the reprex package to render a minimal example based on an .R file:

> reprex::reprex(input="parallelMap-rng.R")
Rendering reprex...
pandoc: /usr/lib/R/site-library/rmarkdown/rmd/h/bootstrap-3.3.5/shim/html5shiv.min.js: openBinaryFile: does not exist (No such file or directory)
Error: pandoc document conversion failed with error 1

The file does not exist under this path on my system, since the shim direcoty is actaully a broken link:

$ ls -l  /usr/lib/R/site-library/rmarkdown/rmd/h/bootstrap-3.3.5/shim 
lrwxrwxrwx 1 root root 43 Jun 29 16:16 /usr/lib/R/site-library/rmarkdown/rmd/h/bootstrap-3.3.5/shim -> ../../../../shiny/www/shared/bootstrap/shim
$ ls -l  /usr/lib/R/site-library/rmarkdown/rmd/h/bootstrap-3.3.5/shim/ 
ls: cannot access '/usr/lib/R/site-library/rmarkdown/rmd/h/bootstrap-3.3.5/shim/': No such file or directory

The relative path itself looks fine, resolving it by hand:

$ ls -l  /usr/lib/R/site-library/shiny/www/shared/bootstrap/shim
total 12
lrwxrwxrwx 1 root root   80 Jun  5 11:16 html5shiv.min.js -> ../../../../../../../../share/twitter-bootstrap/files/html5shiv/html5shiv.min.js
-rw-r--r-- 1 root root 4433 Jun  5 11:16 respond.min.js

However, the bootstrap directory is already a link

ls -l  /usr/lib/R/site-library/rmarkdown/rmd/h/bootstrap-3.3.5
lrwxrwxrwx 1 root root 44 Mär 23 08:25 /usr/lib/R/site-library/rmarkdown/rmd/h/bootstrap-3.3.5 -> ../../../../../../share/javascript/bootstrap

And relative to that directory, the link to the shim directory does not resolve:

$ ls -l  /usr/share/javascript/bootstrap
total 16
drwxr-xr-x 2 root root 4096 Jan  7  2018 css
drwxr-xr-x 2 root root 4096 Jan  7  2018 fonts
drwxr-xr-x 2 root root 4096 Jan  7  2018 js
drwxr-xr-x 3 root root 4096 Jan  7  2018 less
lrwxrwxrwx 1 root root   43 Jun 29 16:16 shim -> ../../../../shiny/www/shared/bootstrap/shim

Please let me know if you need further info.

Greetings
Ralf
