Description James Ralston 2007-04-04 19:04:44 UTC

I'm not sure when the behavior changed, but recent versions of file (including
the one in Fedora Core 6, Rawhide, and the Fedora 7 test releases) no longer
display the name of the executable that generated a core file when examining the
core file.

FC7test2 / Rawhide:

$ rpm -q file; file core.5676
file-4.20-1.fc7
core.5676: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style

FC6:

$ rpm -q file; file core.5676
file-4.19-1.fc6
core.5676: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style

This isn't caused by a change in the structure of core files, as older versions
of file can identify the executable of core files with no problem:

RHEL4:

[transfer core.5676 from the FC7test2 system]
$ rpm -q file; file core.5676 
file-4.10-2.EL4.4
core.5676: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style,
from 'dig'

This might be a recurrence of bug 172015.

This feature seems to be back in version 4.21. If you still are able to
reproduce this behaviour with updated file feel free to reopen this bz.

Comment 3 James Ralston 2007-07-05 16:08:02 UTC

I see no difference in the behavior with version 4.21, for either i386 or x86_64:

$ uname -m; file --version; file core.5254
x86_64
file-4.21
magic file from /usr/share/file/magic
core.5254: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style

$ uname -m; file --version; file core.5901
i686
file-4.21
magic file from /usr/share/file/magic
core.5901: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style

Comment 4 Per Winkvist 2007-07-08 19:40:07 UTC

I've rebuilt file from rawhide and I still don't get file to show program name 
from a core file:
------------
[perra@localhost ~]$ uname -m; rpm -q file; file --version; file core.*
i686
file-4.21-2.fc7
file-4.21
magic file from /usr/share/file/magic
core.2636: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style
core.3689: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style
core.5896: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style
core.7284: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style
