ODP: posix atime/ctime changes despite mtime being set

[Piotr Łobacz]

Hi Sergey,

yes, this is diffoscope command for looking on differences between two builds of same packages. and as you can see on this output the only differences are between timestamps e.g.:

7

-rw-r--r--···0········0········0·····7339·2012-02-16·20:24:42.000000·./usr/src/debug/acpid/2.0.34-r0/acpi_ids.c

7

-rw-r--r--···0········0········0·····7339·2012-02-16·20:24:42.515701·./usr/src/debug/acpid/2.0.34-r0/acpi_ids.c

and I'm not sure why...

Additionally, from what I know this test was run with gnu format not with posix, but I need to confirm it.

BR

Piotr

Hi Piotr,

> The diffoscope is here:

I'm not sure I'm able to correctly interpret that output.  It seems to
indicate that something has changed (e.g. "Offset 1, 47 lines
modified"), but it doesn't say what exactly the difference is.

Can you elaborate please?

Regards,
Sergey
