From e99f6cc469bdc5ea7d92fd3e004dd8dcd75dddbd Mon Sep 17 00:00:00 2001 From: KOLANICH Date: Mon, 17 Aug 2020 20:03:38 +0000 Subject: [PATCH] Added Qt Installer Framework --- archive/qt_installer_framework.ksy | 225 +++++++++++++++++++++++++++++ 1 file changed, 225 insertions(+) create mode 100644 archive/qt_installer_framework.ksy diff --git a/archive/qt_installer_framework.ksy b/archive/qt_installer_framework.ksy new file mode 100644 index 000000000..32a6eaa3f --- /dev/null +++ b/archive/qt_installer_framework.ksy @@ -0,0 +1,225 @@ +meta: + id: qt_installer_framework + title: Qt Installer Framework archive + application: Qt Installer Framework + file-extension: exe + endian: le + encoding: utf-8 + license: GPL-3.0 WITH Qt-GPL-exception-1.0 + xref: + wikidata: Q201904 + +doc: | + Qt installer framework is a set of libs to make SFX installers. Installers usually contain 7zip-compressed archives. Obviously, Qt installer itself is built using this framework. + + Warning 1: KSC has a bug. It makes the computed values be int32_t. Of course their type should be either explicitly specified by a programmer or derived automatically. The workaroind is to just replace all int32_t to int64_t in sources. + Warning 2: don't use this spec on Linux against Qt distribution with overcommit enabled unless you have lot of RAM (> 12 GiB). There is a severe memory leak somewhere (currently I have no idea where exactly). The leak is present in both C++ and python-compiled code. In python even if I have patched the generated source to explicitly free all the `bytes`, `BytesIO`s and `KaitaiStream` objects the leak is still present. At least it is neither in `bytes` nor in `BytesIO`. In C++ I have not patched anything but used move semantics to free the stuff since std::unique_ptr is used. The leak is still present. IDK where it is and how to fix it. + +-license-header: | + GNU General Public License Usage + Alternatively, this file may be used under the terms of the GNU General Public License version 3 as published by the Free Software Foundation with exceptions as appearing in the file LICENSE.GPL3-EXCEPT included in the packaging of this file.
