Title:
[FFe] Update tracker(-miners) to 2.3.0
Status in tracker package in Ubuntu:
Fix Released
Status in tracker-miners package in Ubuntu:
Fix Released
Bug description:
Ubuntu is stuck with tracker 2.1.8 and tracker miners 2.1.6, while
GNOME 3.34 will ship versions 2.3.0 of both.
Main changes since archive version, in tracker:
- Support for storing Musicbrainz metadata in the multimedia ontology.
- Fix detection of files that need writeback
- Fix crashes and invalid memory writes
- Fixed initialization of virtual tables
- Fixed segmentation fault in libtracker-miner
- Don't try to create JSON-LD nodes with unsigned integers
- Handle correctly backreferences in TrackerResource tree
- Fixed handling doubles with exponents in SPARQL
- Don't limit to specific desktop environments
- Fix unichar unescaping
- Correctly Handle BIND in first place of a triples block
- Fix possible deadlock on WAL checkpoint
- Fix some double values not being deleted
- Fixed CHANGES_DONE_HINT handling in TrackerMonitor
- Ported data generator utilities to python3
- Ported functional tests to python3, reformatted to PEP-8
- Correctly apply ignored-directories-with-content filter on monitor updates
- Multiple memory leak and memory corruption fixes
- New SPARQL parser, able to generate SQL that is generally more readable
and at places performs better. Multiple buglets fixed in the process
- Much improved support of SPARQL1.1 features and syntax that was missing:
* Property paths: Allowing to match connectivity between two resources
by an arbitrary length path. There is a number of supported operators
(alternative, sequence, oneOrMany, ...) that can be combined, e.g:
SELECT ?s ?p { ?s ^(nfo:belongsToContainer*)/(nie:url|nie:title)
?p }
Only the negated path operator (!) is not supported at the
moment.
* Support for fully unrestricted queries, eg:
SELECT ?s ?p ?o { ?s ?p ?o } ORDER BY ?o ?p ?s
Queries with unrestricted predicate (?p in the example above) were
just supported in a very restricted set of situations. All those
limitations are gone.
* MINUS allows subtracting the solutions that match the given triples
template, eg:
SELECT ?s { ?s a nfo:Media } MINUS { ?s a nfo:MusicPiece }
- Support for prepared statements. TrackerSparqlStatement can be built
with SELECT queries containing (custom) ~var syntax, and updating
their values before obtaining a cursor.
- tracker-store now automatically shuts down on inactivity.
- More property paths supported, new operators supported are -, +, ? and |,
only the ! operator is not supported yet.
- Improve error handling in DBus backend
- New SPARQL parser, able to support more 1.1 features and generating
friendlier SQL at places. There is initial support for property
paths (/ and ^), and other missing 1.1 syntax (MINUS, SHA384, ...).
More improvements are expected to happen in the future thanks to this.
- Support for prepared statements. TrackerSparqlStatement can be built
with SELECT queries containing (custom) ~var syntax, and updating
their values before obtaining a cursor.
NEWS upstream file changes:
https://gitlab.gnome.org/GNOME/tracker/compare/2.1.8...2.2.99.0#9f621eb5fd3bcb2fa5c7bd228c9b1ad42edc46c8
While in tracker-miners:
- Support for reading Musicbrainz metadata from audio files.
- Tracker Writeback now uses GStreamer to write metadata to audio files,
instead of depending on taglib directly.
- Directories will now be ignored if they contain a file named `.nomedia`.
A file named `.trackerignore` has the same effect, but the `.nomedia` file
brings us in line with Android.
- Removed obsolete 'max-media-art-width' setting.
- Functional tests now use python3
- Fix text extractor handling of non-existent files
- Fix indexing of tracks in FLAC files
- Whitelist syscall fadvise64_64
- Fix failed functional tests being reported as successful
- Fixes to desktop file indexing
- The functionality of tracker-miner-apps has been adopted by
tracker-miner-fs/tracker-extract.
- Updated tracker-miner-fs and tracker-miner-rss to use TrackerResource

So changes are quite a lot and with lots of improvements, that it's
quite important to test a bit more before next LTS, so having in 19.10
would be smart.
