From d80de5a929f3c3eec7d0baae8c5d48ccd981ae12 Mon Sep 17 00:00:00 2001 From: Tobias Fella Date: Wed, 14 Aug 2024 22:24:16 +0200 Subject: [PATCH 1/2] Overhaul connection management As described in #781 Roughly: - Turn Connection into a type that only exists in an initiated state (from the API user's perspective, at least) - To do this, pull connection setup, etc. out into a new PendingConnection type - Add easy-to-use account login and restoration functions to AccountRegistry - Make connections do the expected things (cache, sync loop, etc.) by default --- CMakeLists.txt | 4 + Quotient/accountregistry.cpp | 79 ++---- Quotient/accountregistry.h | 19 +- Quotient/config.cpp | 55 ++++ Quotient/config.h | 25 ++ Quotient/connection.cpp | 273 +------------------ Quotient/connection.h | 124 ++------- Quotient/connection_p.h | 31 +-- Quotient/pendingconnection.cpp | 424 ++++++++++++++++++++++++++++++ Quotient/pendingconnection.h | 51 ++++ Quotient/ssosession.cpp | 33 +-- autotests/testcrosssigning.cpp | 5 +- autotests/testcryptoutils.cpp | 5 +- autotests/testkeyverification.cpp | 7 +- autotests/testutils.cpp | 36 +-- quotest/quotest.cpp | 49 ++-- 16 files changed, 709 insertions(+), 511 deletions(-) create mode 100644 Quotient/config.cpp create mode 100644 Quotient/config.h create mode 100644 Quotient/pendingconnection.cpp create mode 100644 Quotient/pendingconnection.h diff --git a/CMakeLists.txt b/CMakeLists.txt index d402ccf04..03356a79d 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -190,6 +190,8 @@ target_sources(${QUOTIENT_LIB_NAME} PUBLIC FILE_SET HEADERS BASE_DIRS .
