Package: mc Version: 3:4.7.0.9-1 Severity: normal Hi there,
When inspecting tar balls created tar's --posix option, file paths
(path + file name) exceeding about 100 characters in length are not
shown properly, subdirectories are skipped alltogether.
How to repeat (sorry, overlong lines):
echo 'asdf'
>012345678-10--------20--------30--------40--------50--------60--------70--------80--------.file1
touch
012345678-10--------20--------30--------40--------50--------60--------70--------80--------.file2
mkdir
posix-tar-test/012345678-10--------20--------30--------40--------50--------60--------70--------80--------
touch
posix-tar-test/012345678-10--------20--------30--------40--------50--------60--------70--------80--------/subfile
tar --posix -cvf posix-tar-test.tar posix-tar-test
Then start mc and inspect posix-tar-test.tar.
Expected behaviour:
In posix-tar-test/, two files, first length 5, second length 0, and a
sub-directory. In that sub-directory, a single file length 0.
Compare to the output to 'tar -tvf posix-tar-test.tar'.
Observed behaviour:
Three items named
"012345678-10--------20--------30--------40--------50--------60--------70--------80---"
all type file and length five (i.e. taken from .file1).
Examining the tar ball ...

... suggests mc's tar viewer picks file names from the second (legacy
format) blob and caches that information, while tar --list does the
right thing and reads the pax header (first blob).
