dumpsys prints a blank line after every namespace block and after a
change history, and the generation registry and any vendor dumps follow
the last block before the section trailer. A record ran until the next
`_id:` line, heading or trailer, so the last row of the section
absorbed those dumps into whichever field came last.
A blank line now closes the record being read; lines that follow it
without an `_id:` are skipped until the next row or heading. The fixture
carries a generation registry after its last block, modelled on the
AOSP dump, and the last row is pinned to exactly its own fields.
A dumpsys settings row can end in `tag:` and, on some vendor builds, in
`isValuePreservedInRestore:` or a bare `notPreservedInRestore` token.
The parser only peeled `default:` and `defaultSystemSet:` off the end
of a record, so on a row without a default those tokens stayed inside
the value, and on a row with one they landed in `defaultSystemSet`. A
value of `0 tag:null` is not the safe value `0`, so a setting at its
safe value was reported as dangerous; these are the false positives
measured in #912.
The metadata keys are ordered fields like the rest of the record, so
`_split_fields` reads them now, which also replaces the separate
handling of the default. The bare token has no `key:` shape and is
printed last, so it is stripped first and recorded as
`isValuePreservedInRestore: false`.
The bugreport fixture gains the three row shapes from #912: a restore
flag after `defaultSystemSet:`, and a `tag:` or a bare token directly
after the value. Two of them sit on dangerous settings at their safe
value, so the unchanged alert count of one is the false-positive check.
The `dumpsys settings` parser matched a single regex per line, which
truncated every value that spans more than one line and, when
`defaultSystemSet:` did not fall on the first line, left the trailing
`default:` metadata inside the value. It also keyed results by setting
name within a namespace, so a name recorded twice kept only the last row
and a row without a `pkg:` field was dropped entirely.
Replace it with a line loop that accumulates one record at a time and
splits the `key:value` fields once the whole record has been read.
Results become a list of records carrying the fields dumpsys prints:
namespace, user, _id, name, value, pkg, default and defaultSystemSet,
plus the per-setting change history. History timestamps are printed
without a year, so they are resolved against the "ending at:" time of
the section and serialized into the timeline. This shows which package
changed a security-relevant setting, and when.
The androidqf settings module shares this artifact, so it now emits the
same record shape.
