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_pkware_encode.c | 158 +++++++++++++-------------- 1 file changed, 79 insertions(+), 79 deletions(-) (limited to 'src/Common/libzip/zip_source_pkware_encode.c') diff --git a/src/Common/libzip/zip_source_pkware_encode.c b/src/Common/libzip/zip_source_pkware_encode.c index 1e8f42c3..5958af40 100644 --- a/src/Common/libzip/zip_source_pkware_encode.c +++ b/src/Common/libzip/zip_source_pkware_encode.c @@ -3,7 +3,7 @@ Copyright (C) 2009-2020 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 @@ -58,21 +58,21 @@ zip_source_pkware_encode(zip_t *za, zip_source_t *src, zip_uint16_t em, int flag zip_source_t *s2; if (password == NULL || src == NULL || em != ZIP_EM_TRAD_PKWARE) { - zip_error_set(&za->error, ZIP_ER_INVAL, 0); - return NULL; + zip_error_set(&za->error, ZIP_ER_INVAL, 0); + return NULL; } if (!(flags & ZIP_CODEC_ENCODE)) { - zip_error_set(&za->error, ZIP_ER_ENCRNOTSUPP, 0); - return NULL; + zip_error_set(&za->error, ZIP_ER_ENCRNOTSUPP, 0); + return NULL; } if ((ctx = trad_pkware_new(password, &za->error)) == NULL) { - return NULL; + return NULL; } if ((s2 = zip_source_layered(za, src, pkware_encrypt, ctx)) == NULL) { - trad_pkware_free(ctx); - return NULL; + trad_pkware_free(ctx); + return NULL; } return s2; @@ -86,15 +86,15 @@ encrypt_header(zip_source_t *src, struct trad_pkware *ctx) { zip_uint8_t *header; if (zip_source_stat(src, &st) != 0) { - _zip_error_set_from_source(&ctx->error, src); - return -1; + _zip_error_set_from_source(&ctx->error, src); + return -1; } _zip_u2d_time(st.mtime, &dostime, &dosdate); if ((ctx->buffer = _zip_buffer_new(NULL, ZIP_CRYPTO_PKWARE_HEADERLEN)) == NULL) { - zip_error_set(&ctx->error, ZIP_ER_MEMORY, 0); - return -1; + zip_error_set(&ctx->error, ZIP_ER_MEMORY, 0); + return -1; } header = _zip_buffer_data(ctx->buffer); @@ -102,10 +102,10 @@ encrypt_header(zip_source_t *src, struct trad_pkware *ctx) { /* generate header from random bytes and mtime see appnote.iz, XIII.
