Bug ID: 105422
Summary: filesystem::copy does not throw exceptions when a
subdirectory exists
Product: gcc
Version: 11.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: mpie@msc-ge.com
Target Milestone: ---
Created attachment 52895
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52895&action=edit
Example file to reproduce behaviour
Hi,
in Ubuntu 21.10 a recursive filesystem::copy() does correctly throw an
exception if a file can't be read. But it will not throw an exception if there
is an empty subdirectory. The destination will therefore miss a file without a
report. Also the error code will be empty.
See the output of the attached copy_bug.cpp
$ c++ copy_bug.cpp -o copy_bug --std=c++17
$ ./copy_bug
Copytest with withSubDir=0
Exception: filesystem error: cannot copy: Permission denied [test/source]
[test/dest]
Error code: Permission denied
Copytest with withSubDir=1
$ tree -p test
test

├── [drwxrwxr-x] dest_ec
│ └── [drwxrwxr-x] subdir
└── [drwxrwxr-x] source
├── [drwxrwxr-x] subdir
