diskdrake: fix a crash on whole disk filesystems (mga#26849)

2020-06-23T20:52:19+00:00

When a disk has a filesystem directly without a partition table,
libparted tells us the partition table is of type loop and we don't
have code to handle that, causing a crash:

Can't locate partition_table/loop.pm in @INC (you may need to install the partition_table::loop module) (@INC contains: /usr/lib/libDrakX /usr/local/lib64/perl5 /usr/local/share/perl5/5.32 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at /usr/lib/libDrakX/partition_table.pm line 287.
Perl's trace:

We should probably be more generic and treat the same way any partition
table type name we don't know rather than crashing.

When writing a GPT partition table, merge all actions into a single commit.

This avoids unnecessary udev events, which in some cases were causing
udevd to trigger a kernel partition table reread, causing the kernel
to get out of sync with drakx.

In order to do so, the libparted bindings are enhanced so that we
manipulate a 'ped_disk' object:
- disk_open() returns such an object
- set_disk_type() is removed
- disk_commit() writes back the partition table and tell the kernel
  about it
  if we fails to write the partition table, we let
  partition_table::write() fire an exceptionc
  if we only have succeed in writing the partition table, we let
  partition_table::write() try harder (umounting partitions before
  trying againt to tell the kernel again)
- need_to_tell_kernel() is overrided

The last change is needed because we now tell the kernel about the new
partition layout in partition_table::gpt::write() when calling
disk_commit() while previously we were deferring that to
partition_table::write() which after having called the gpt's write()
calls tell_kernel() -> c::tell_kernel_to_reread_partition_table()

So we must tell partition_table::write() that telling the kernel to
reread the partition_table is not needed if we already succeeded in
that.

Record the partition table type when initialising a partition table.

When performing an automatic install that uses the clear or clearall
option, we don't read the current partition table, so the current
partition table type was not getting recorded in $hd->{pt_table_type}.
This information is needed to determine whether a BIOS boot partition
is required.
