From de1ab01e8ebf04a3503d8450e6b924c7bb160853 Mon Sep 17 00:00:00 2001 From: Nick Clifton Date: Fri, 20 Jan 2017 10:17:42 +0000 Subject: Sync zlib sources with GCC, upgrading to 1.2.10. Changes in 1.2.10 (2 Jan 2017) - Avoid warnings on snprintf() return value - Fix bug in deflate_stored() for zero-length input - Fix bug in gzwrite.c that produced corrupt gzip files - Remove files to be installed before copying them in Makefile.in - Add warnings when compiling with assembler code Changes in 1.2.9 (31 Dec 2016) - Fix contrib/minizip to permit unzipping with desktop API [Zouzou] - Improve contrib/blast to return unused bytes - Assure that gzoffset() is correct when appending - Improve compress() and uncompress() to support large lengths - Fix bug in test/example.c where error code not saved - Remedy Coverity warning [Randers-Pehrson] - Improve speed of gzprintf() in transparent mode - Fix inflateInit2() bug when windowBits is 16 or 32 - Change DEBUG macro to ZLIB_DEBUG - Avoid uninitialized access by gzclose_w() - Allow building zlib outside of the source directory - Fix bug that accepted invalid zlib header when windowBits is zero - Fix gzseek() problem on MinGW due to buggy _lseeki64 there - Loop on write() calls in gzwrite.c in case of non-blocking I/O - Add --warn (-w) option to ./configure for more compiler warnings - Reject a window size of 256 bytes if not using the zlib wrapper - Fix bug when level 0 used with Z_HUFFMAN or Z_RLE - Add --debug (-d) option to ./configure to define ZLIB_DEBUG - Fix bugs in creating a very large gzip header - Add uncompress2() function, which returns the input size used - Assure that deflateParams() will not switch functions mid-block - Dramatically speed up deflation for level 0 (storing) - Add gzfread(), duplicating the interface of fread() - Add gzfwrite(), duplicating the interface of fwrite() - Add deflateGetDictionary() function - Use snprintf() for later versions of Microsoft C - Fix *Init macros to use z_ prefix when requested - Replace as400 with os400 for OS/400 support [Monnerat] - Add crc32_z() and adler32_z() functions with size_t lengths - Update Visual Studio project files [AraHaan] --- zlib/test/example.c | 17 +++++++++-------- zlib/test/infcover.c | 18 +++++++++--------- zlib/test/minigzip.c | 12 ++++++------ 3 files changed, 24 insertions(+), 23 deletions(-) (limited to 'zlib/test') diff --git a/zlib/test/example.c b/zlib/test/example.c index 138a699..eee17ce 100644 --- a/zlib/test/example.c +++ b/zlib/test/example.c @@ -1,5 +1,5 @@ /* example.c -- usage example of the zlib compression library - * Copyright (C) 1995-2006, 2011 Jean-loup Gailly. + * Copyright (C) 1995-2006, 2011, 2016 Jean-loup Gailly * For conditions of distribution and use, see copyright notice in zlib.h */ @@ -26,13 +26,13 @@ } \ } -z_const char hello[] = "hello, hello!"; +static z_const char hello[] = "hello, hello!"; /* "hello world" would be more standard, but the repeated "hello" * stresses the compression code better, sorry... */ -const char dictionary[] = "hello"; -uLong dictId; /* Adler32 value of the dictionary */ +static const char dictionary[] = "hello"; +static uLong dictId; /* Adler32 value of the dictionary */ void test_deflate OF((Byte *compr, uLong comprLen)); void test_inflate OF((Byte *compr, uLong comprLen, @@ -59,13 +59,13 @@ void *myalloc(q, n, m) void *q; unsigned n, m; { - q = Z_NULL; + (void)q; return calloc(n, m); } void myfree(void *q, void *p) { - q = Z_NULL; + (void)q; free(p); } @@ -432,7 +432,7 @@ void test_sync(compr, comprLen, uncompr, uncomprLen) d_stream.next_out = uncompr; d_stream.avail_out = (uInt)uncomprLen; - inflate(&d_stream, Z_NO_FLUSH); + err = inflate(&d_stream, Z_NO_FLUSH); CHECK_ERR(err, "inflate"); d_stream.avail_in = (uInt)comprLen-2; /* read all compressed data */ @@ -573,7 +573,8 @@ int main(argc, argv) } #ifdef Z_SOLO - argc = strlen(argv[0]); + (void)argc; + (void)argv; #else test_compress(compr, comprLen, uncompr, uncomprLen); diff --git a/zlib/test/infcover.c b/zlib/test/infcover.c index fe3d920..2be0164 100644 --- a/zlib/test/infcover.c +++ b/zlib/test/infcover.c @@ -1,5 +1,5 @@ /* infcover.c -- test zlib's inflate routines with full code coverage - * Copyright (C) 2011 Mark Adler + * Copyright (C) 2011, 2016 Mark Adler * For conditions of distribution and use, see copyright notice in zlib.h */ @@ -237,14 +237,14 @@ local void mem_done(z_stream *strm, char *prefix) /* Decode a hexadecimal string, set *len to length, in[] to the bytes.
