From 8f78d1421581c2f7953a589909b149f352e3a971 Mon Sep 17 00:00:00 2001 From: Martchus Date: Thu, 20 Jun 2024 01:22:45 +0200 Subject: [PATCH] Fix re-connect when process status is considered and Syncthing restarted MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When Syncthing restarts itself, its main process is not terminating (as its main process is just a monitoring process). The "Consider process status …" feature was relying on the process being stopped and started again as trigger for trying to re-connect, though. To make it also work when Syncthing restarts itself, this change checks the log for an exiting message of the monitoring process and considers the process running again when the GUI address is logged again. This fixes https://github.com/Martchus/syncthingtray/issues/236. Notifications are not (yet) suppressed. (Not sure how easy it is and how much sense it makes.) --- syncthingwidgets/misc/syncthinglauncher.cpp | 18 +++++++++++++++++- syncthingwidgets/misc/syncthinglauncher.h | 5 ++++- syncthingwidgets/settings/settings.cpp | 2 +- tray/gui/traywidget.cpp | 11 +++++++++++ tray/gui/traywidget.h | 1 + 5 files changed, 34 insertions(+), 3 deletions(-) diff --git a/syncthingwidgets/misc/syncthinglauncher.cpp b/syncthingwidgets/misc/syncthinglauncher.cpp index 29a40cd..d2d5dcb 100644 --- a/syncthingwidgets/misc/syncthinglauncher.cpp +++ b/syncthingwidgets/misc/syncthinglauncher.cpp @@ -45,6 +45,8 @@ SyncthingLauncher::SyncthingLauncher(QObject *parent) , m_relevantConnection(nullptr) , m_guiListeningUrlSearch("Access the GUI via the following URL: ", "\n\r", std::string_view(), std::bind(&SyncthingLauncher::handleGuiListeningUrlFound, this, std::placeholders::_1, std::placeholders::_2)) + , m_exitSearch("Syncthing exited: ", "\n\r", std::string_view(), + std::bind(&SyncthingLauncher::handleExitFound, this, std::placeholders::_1, std::placeholders::_2)) #ifdef SYNCTHINGWIDGETS_USE_LIBSYNCTHING , m_libsyncthingLogLevel(LibSyncthing::LogLevel::Info) #endif @@ -332,6 +334,7 @@ void SyncthingLauncher::handleLoggingCallback(LibSyncthing::LogLevel level, cons void SyncthingLauncher::handleOutputAvailable(QByteArray &&data) { m_guiListeningUrlSearch(data.data(), static_cast(data.size())); + m_exitSearch(data.data(), static_cast(data.size())); if (isEmittingOutput()) { emit outputAvailable(data); } else { @@ -339,12 +342,23 @@ void SyncthingLauncher::handleOutputAvailable(QByteArray &&data) } } -void SyncthingLauncher::handleGuiListeningUrlFound(CppUtilities::BufferSearch &, std::string &&searchResult) +void SyncthingLauncher::handleGuiListeningUrlFound(CppUtilities::BufferSearch &search, std::string &&searchResult) { m_guiListeningUrl.setUrl(QString::fromStdString(searchResult)); + std::cerr << EscapeCodes::Phrases::Info << "Syncthing GUI available: " << searchResult << EscapeCodes::Phrases::End; + search.reset(); emit guiUrlChanged(m_guiListeningUrl); } +void SyncthingLauncher::handleExitFound(CppUtilities::BufferSearch &search, std::string &&searchResult) +{ + m_guiListeningUrl.clear(); + std::cerr << EscapeCodes::Phrases::Info << "Syncthing exited: " << searchResult << EscapeCodes::Phrases::End; + emit guiUrlChanged(m_guiListeningUrl); + emit exitLogged(std::move(searchResult)); + search.reset(); +} + void SyncthingLauncher::terminateDueToMeteredConnection() { if (!isRunning()) { @@ -366,6 +380,8 @@ void SyncthingLauncher::runLibSyncthing(const LibSyncthing::RuntimeOptions &runt LibSyncthing::setLoggingCallback(bind(&SyncthingLauncher::handleLoggingCallback, this, _1, _2, _3)); emit runningChanged(true); const auto exitCode = LibSyncthing::runSyncthing(runtimeOptions); + m_guiListeningUrl.clear(); + emit guiUrlChanged(m_guiListeningUrl); emit exited(static_cast(exitCode), exitCode == 0 ?
