Subject: [PATCH] blscfg: sort BLS entries by 'version' field
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8
|
||
Content-Transfer-Encoding: 8bit
|
||
|
||
This partially reverts ‘Use BLS fragment filename as menu entry id and
|
||
for criteria to sort’. Sorting by filename only gives the correct order
|
||
if the BLS entries are generated by a version of ostree after this patch
|
||
https://github.com/ostreedev/ostree/commit/9f48e212a3bf9ed418fb3216e4f834d581bc520e
|
||
to use the version (higher is newer) in the filename. Older ostrees,
|
||
including all releases at the time of writing, use the index (lower is
|
||
newer) in the filename, so sorting by filename produces the reverse
|
||
order.
|
||
|
||
Sorting by 'version' field matches libostree's own
|
||
compare_boot_loader_configs(), so I think it's more correct than relying
|
||
on the filename, particularly since we've already gone to the trouble of
|
||
parsing all the fields in the file.
