Mark Adler	eff308af42	Fix a bug when getting a gzip header extra field with inflate(). If the extra field was larger than the space the user provided with inflateGetHeader(), and if multiple calls of inflate() delivered the extra header data, then there could be a buffer overflow of the provided space. This commit assures that provided space is not exceeded.	2 years ago

Mark Adler	441a2ac602	Have build test report library version if it doesn't match zlib.h.	3 years ago
Mark Adler	ec3df00224	Correct incorrect inputs provided to the CRC functions. The previous releases of zlib were not sensitive to incorrect CRC inputs with bits set above the low 32. This commit restores that behavior, so that applications with such bugs will continue to operate as before.	3 years ago

Mark Adler	735eaa1ebd	Eliminate use of ULL constants. 0xffffffffffffffffULL was causing warnings for C99 usage. The suffix for the constant is not necessary anyway, so this commit removes them.	3 years ago

Mark Adler	58ca4e57ce	Fix unztell64() in minizip to work past 4GB. (Daniël Hörchner) The issue is that unztell64() does not return the correct value if the position in the current file (in the ZIP archive) is beyond 4 GB. The cause is that unzReadCurrentFile() does not account for pfile_in_zip_read_info->stream.total_out at line 1854 of unzip.c wrapping around (it is a 32-bit variable). So, on line 1860 uTotalOutAfter can be less than uTotalOutBefore, propagating the wraparound to uOutThis, which in turn is added to pfile_in_zip_read_info->total_out_64. That has the effect of subtracting 4 GB.	3 years ago

Mark Adler	79baebe50e	Avoid adding empty gzip member after gzflush with Z_FINISH.	6 years ago
Mark Adler	0e96d8e7c7	Explicitly note that the 32-bit check values are 32 bits.	6 years ago
Mark Adler	deb44b5742	Use ARM crc32 instructions if the ARM architecture has them. The ARM crc32 instructions will be used only if an architecture is explicitly specified at compile time that has those instructions. For example, -march=armv8.1-a or -march=armv8-a+crc, or if the machine being compiled on has the instructions, -march=native.	6 years ago
Mark Adler	52fc78baf2	Add use of the ARMv8 crc32 instructions when requested. Define the macro Z_ARM_CRC32 at compile time to use the ARMv8 (aarch64) crc32x and crc32b instructions. This code does not check for the presence of the crc32 instructions. Those instructions are optional for ARMv8.0, though mandatory for ARMv8.1 and later. The use of the crc32 instructions is about ten times as fast as the software braided calculation of the CRC-32. This can noticeably speed up the decompression of gzip streams.	6 years ago
Mark Adler	aec89faa2e	Correct comment in crc32.c.	6 years ago
Mark Adler	0d36ec47f3	Don't bother computing check value after successful inflateSync(). inflateSync() is used to skip invalid deflate data, which means that the check value that was being computed is no longer useful. This commit turns off the check value computation, and furthermore allows a successful return if the compressed data terminated in a graceful manner. This commit also fixes a bug in the case that inflateSync() is used before a header is ever processed. In that case, there is no knowledge of a trailer, so the remainder is treated as raw.	6 years ago
Mark Adler	7c0c75e990	Use atomic test and set, if available, for dynamic CRC tables.	6 years ago
Mark Adler	f8719f5ae5	Speed up software CRC-32 computation by a factor of 1.5 to 3. Use the interleaved method of Kadatch and Jenkins in order to make use of pipelined instructions through multiple ALUs in a single core. This also speeds up and simplifies the combination of CRCs, and updates the functions to pre-calculate and use an operator for CRC combination.	6 years ago
Mark Adler	41d86c73b2	Add crc32_combine_gen() and crc32_combine_op() for fast combines. When the same len2 is used repeatedly, it is faster to use crc32_combine_gen() to generate an operator, that is then used to combine CRCs with crc32_combine_op().	6 years ago
Mark Adler	47cb412957	Add tables for crc32_combine(), to speed it up by a factor of 200.	6 years ago
Mark Adler	921d81b2a8	Fix the zran.c example to work on a multiple-member gzip file.	6 years ago
Mark Adler	354fa43d12	Add gznorm.c example, which normalizes gzip files.	6 years ago
Mark Adler	cd16ff0b3a	Show all the codes for the maximum tables size in enough.c.	7 years ago
Mark Adler	d00c147f53	Clarify that prefix codes are counted in enough.c. There is no assurance that all prefix codes are reachable as optimal Huffman codes for the numbers of symbols encountered in a deflate block. This code considers all possible prefix codes, which might be a larger set than all possible Huffman codes, depending on the constraints.	7 years ago
Mark Adler	5b1381006b	Use inline function instead of macro for index in enough.c.	7 years ago
Mark Adler	8ba2cdb6bd	Clean up code style in enough.c, update version.	7 years ago

Mark Adler	4346a16853	Assure that the number of bits for deflatePrime() is valid.	7 years ago
Mark Adler	5c44459c3b	Fix a bug that can crash deflate on some input when using Z_FIXED. This bug was reported by Danilo Ramos of Eideticom, Inc. It has lain in wait 13 years before being found! The bug was introduced in zlib 1.2.2.2, with the addition of the Z_FIXED option. That option forces the use of fixed Huffman codes. For rare inputs with a large number of distant matches, the pending buffer into which the compressed data is written can overwrite the distance symbol table which it overlays. That results in corrupted output due to invalid distances, and can result in out-of-bound accesses, crashing the application. The fix here combines the distance buffer and literal/length buffers into a single symbol buffer. Now three bytes of pending buffer space are opened up for each literal or length/distance pair consumed, instead of the previous two bytes. This assures that the pending buffer cannot overwrite the symbol table, since the maximum fixed code compressed length/distance is 31 bits, and since there are four bytes of pending space for every three bytes of symbol space.	7 years ago
