[Bug 2130465] Re: cp commands fails when process is in deleted directory

[Gordon Lack]

Sorry!
I posted a link to the wrong issue on the coreutils git.
The actual issue is:
  https://github.com/uutils/coreutils/issues/9105
which has a fix posted against it (https://github.com/uutils/coreutils/pull/9249).

[The 9116 issues I mentioned is actually against install, for which a
fix has been posted recently too]

Title:
  cp commands fails when process is in deleted directory

Status in rust-coreutils:
  Unknown
Status in rust-coreutils package in Ubuntu:
  Triaged

Bug description:
  If the current directory of a process is deleted and the process runs
  the Rust cp command it will faile with:

  /usr/lib/cargo/bin/coreutils/cp: failed to get current directory No
  such file or directory (os error 2)

  The GNU version of cp does not have this issue.

  As a result, some automated build processes (which arrive at this
  situation) now fail to run.

  You can see the error by using this simple shell script:

  ====================
  #!/bin/sh
  #

  echo Rust core-utils

  cd $HOME
  mkdir -p cu-test-base
  touch cu-test-base/file1 cu-test-base/file2
  mkdir -p cu-test
  cd cu-test
  rm -rf $HOME/cu-test
  /usr/lib/cargo/bin/coreutils/cp  -r $HOME/cu-test-base  $HOME/cu-test
  ls $HOME/cu-test

  #####################

  echo GNU core-utils

  cd $HOME
  mkdir -p cu-test-base
  touch cu-test-base/file1 cu-test-base/file2
  mkdir -p cu-test
  cd cu-test
  rm -rf $HOME/cu-test
  /usr/bin/gnucp  -r $HOME/cu-test-base  $HOME/cu-test
  ls $HOME/cu-test
