commit 2d24229055dcef2b6c7c4f83697fb7b6caa82ce1 Author: Alex Catarineu acat@torproject.org AuthorDate: Wed Oct 16 23:01:12 2019 +0200
Bug 31740: Remove some unnecessary RemoteSettings instances
More concretely, SearchService.jsm 'hijack-blocklists' and url-classifier-skip-urls.
Avoid creating instance for 'anti-tracking-url-decoration'.
If prefs are disabling their usage, avoid creating instances for 'cert-revocations' and 'intermediates'.
Do not ship JSON dumps for collections we do not expect to need. For the ones in the 'main' bucket, this prevents them from being synced unnecessarily (the code in remote-settings does so for collections in the main bucket for which a dump or local data exists). For the collections in the other buckets, we just save some size by not shipping their dumps.
We also clear the collections database on the v2 -> v3 migration. --- browser/components/search/SearchSERPTelemetry.jsm | 6 ------ .../url-classifier/UrlClassifierFeatureBase.cpp | 2 +- netwerk/url-classifier/components.conf | 6 ------ security/manager/ssl/RemoteSecuritySettings.jsm | 23 ++++++++++++++++++++++ services/settings/IDBHelpers.jsm | 4 ++++ services/settings/dumps/blocklists/moz.build | 14 +++++-------- services/settings/dumps/main/moz.build | 8 -------- services/settings/dumps/security-state/moz.build | 1 - .../components/antitracking/antitracking.manifest | 2 +- toolkit/components/antitracking/components.conf | 7 ------- toolkit/components/search/SearchService.jsm | 2 -- 11 files changed, 34 insertions(+), 41 deletions(-)
