If the actual metadata version is 1, then the dirty bitset will not be
present. But the superblock was trying to write it because of the
overridden md version.
* [file_utils] spin-off syscall-related file operations
1. Eliminate the potential circular dependency between
persistent-data/block.h and persistent-data/file_utils.h,
if the former one wants to include the latter.
2. Avoid namespace pollution by removing the "using namespace std"
declaration in block.tcc.
3. Correct the header hierarchy: base/xml_utils.h now no longer
depends on the higher-level persistent-data/file_utils.h
* [file_utils] support block files in get_file_length()
When check_check is used with --clear-needs-check-flag option,
device needs to be opened in RW exclusive mode, but for this
existing RO exlusive open must be closed.
LVM2 will consider version 0.5.3 as a version without flag support
for cache_check since it cannot successfully pass cache_check.
TODO: when 'RO' parts detects there is nothing to 'clear' it should
completely skip RW open to avoid udev rule processing.
Template array exist in the namespace persistent_data as well as in std
of C++11. Explicitly use the one from persistent_data.
This fixes compilation bugs with CXXFLAGS=-std=gnu++11 together with
gcc 4.8.3 and boost 1.55.
Class shared_ptr exist in the namespace std for C++11 as well as in boost.
Explicitly use the one from boost in order to be compatible.
This fixes compilation bugs with CXXFLAGS=-std=gnu++11 together with
gcc 4.8.3 and boost 1.55.
We had a cycle from transaction_manager <-> space_map, and also from
the ref_counters back up to the tm.
This prevented objects being destroyed when various programs exited.
From now on we'll try and only use a shared ptr if ownership is
implied. Otherwise a reference will be used (eg, for up pointers).
