From 1fc4168b81f565feab409b92ccb61c57a1c550eb Mon Sep 17 00:00:00 2001 From: DLL125 <134442578+DLL125@users.noreply.github.com> Date: Thu, 25 May 2023 12:52:53 +0200 Subject: Update Libzip to latest 1.9.2 (#1071) * Libzip 1.9.2 Updated Libzip to latest version 1.9.2 and changed version number in the config.h from 1.7.3 to 1.9.2. Not sure if anything else needs to be tweaked :) * Modified Libzip to work with Visual studio * Update README.md Update libzip copyright. * Added the missing files. I've added the missing files zipconf.h and config.h, I've missed those sorry for that! --- src/Common/libzip/zip_source_zip_new.c | 147 ++++++++++++++++----------------- 1 file changed, 73 insertions(+), 74 deletions(-) (limited to 'src/Common/libzip/zip_source_zip_new.c') diff --git a/src/Common/libzip/zip_source_zip_new.c b/src/Common/libzip/zip_source_zip_new.c index 6d547f0e..68394b78 100644 --- a/src/Common/libzip/zip_source_zip_new.c +++ b/src/Common/libzip/zip_source_zip_new.c @@ -1,9 +1,9 @@ /* zip_source_zip_new.c -- prepare data structures for zip_fopen/zip_source_zip - Copyright (C) 2012-2019 Dieter Baron and Thomas Klausner + Copyright (C) 2012-2021 Dieter Baron and Thomas Klausner This file is part of libzip, a library to manipulate ZIP archives. - The authors can be contacted at + The authors can be contacted at Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions @@ -38,50 +38,45 @@ static void _zip_file_attributes_from_dirent(zip_file_attributes_t *attributes, zip_dirent_t *de);
