From 85467e7cb9920e1131ebb3e30adc290ff36f3fd7 Mon Sep 17 00:00:00 2001 From: Miklos Vajna Date: Wed, 14 Oct 2020 17:16:22 +0200 Subject: tdf#137356 framework: fix opening the same document twice for long loads If the document loading is long enough that the statusbar is updated, then we can have this situation that we start loading the document, then spin the main loop during load and do a second load of the same document as part of the main loop spinning: #0 SwDoc::SwDoc() (this=0x1c6a180) at sw/source/core/doc/docnew.cxx:194 ... #6 0x00007ffff359a6dd in SfxBaseModel::load(com::sun::star::uno::Sequence const&) (this=0x1c5c260, seqArguments=uno::Sequence of length 15 = {...}) ... #33 0x00007fffeeb81ecd in Application::Reschedule(bool) (i_bAllEvents=true) at vcl/source/app/svapp.cxx:460 ... #36 0x00007ffff4265251 in framework::StatusIndicator::start(rtl::OUString const&, int) (this=0x1aace80, sText="Loading document...", nRange=1000000) at framework/source/helper/statusindicator.cxx:51 #37 0x00007fffd026dfd3 in XMLReader::Read(SwDoc&, rtl::OUString const&, SwPaM&, rtl::OUString const&) (this=0x1bb7d20, rDoc=..., rBaseURL="file:///.../test.odt", rPaM=SwPaM = {...}, rName="") at sw/source/filter/xml/swxml.cxx:630 ... #42 0x00007ffff359a6dd in SfxBaseModel::load(com::sun::star::uno::Sequence const&) (this=0x1bce4d0, seqArguments=uno::Sequence of length 15 = {...}) at sfx2/source/doc/sfxbasemodel.cxx:1883 The reason for this is is that by the time LoadEnv::impl_searchAlreadyLoaded() searches for frames which already have this doc open, the first load is still in progress, and we assiciate the frame with its controller (which has the URL) only once the load finishes. Fix the problem by setting the URL on the frame directly for the duration of the load: this way an in-progress load also counts as a duplicate and we'll have just one document open at the end. Regression from commit 74ac65c49cc1d53b1aa93c2b7c720255867aace2 (#i114963# Enable IPC before OpenClients to allow client connections when printing., 2016-09-06), we just didn't process incoming requests on the socket before, so the problem was less visible.
