Mark Adler	44e8ac810d	Handle case where inflateSync used when header never processed. If zlib and/or gzip header processing was requested, but a header was never provided and inflateSync was used successfully, then the inflate state would be inconsistent, trying to compute a check value but with no flags set. This commit sets the inflate mode to raw in this case, since there is no other assumption that can be made if a header was requested but never seen.	8 years ago

Mark Adler	b7fbee2156	Use a uniform approach for the largest value of an unsigned type.	8 years ago
Mark Adler	b516b4bdd7	Do a more thorough check of the state for every stream call. This verifies that the state has been initialized, that it is the expected type of state, deflate or inflate, and that at least the first several bytes of the internal state have not been clobbered.	8 years ago
Mark Adler	7096424f23	Clean up type conversions.	8 years ago
Mark Adler	2edb94a302	Avoid casting an out-of-range value to long.	8 years ago
Mark Adler	9852c209ac	Add option to not compute or check check values. The undocumented (except in these commit comments) function inflateValidate(strm, check) can be called after an inflateInit(), inflateInit2(), or inflateReset2() with check equal to zero to turn off the check value (CRC-32 or Adler-32) computation and comparison. Calling with check not equal to zero turns checking back on. This should only be called immediately after the init or reset function. inflateReset() does not change the state, so a previous inflateValidate() setting will remain in effect. This also turns off validation of the gzip header CRC when present. This should only be used when a zlib or gzip stream has already been checked, and repeated decompressions of the same stream no longer need to be validated.	8 years ago
Mark Adler	6cef1de740	Fix bug that accepted invalid zlib header when windowBits is zero. When windowBits is zero, the size of the sliding window comes from the zlib header. The allowed values of the four-bit field are 0..7, but when windowBits is zero, values greater than 7 are permitted and acted upon, resulting in large, mostly unused memory allocations. This fix rejects such invalid zlib headers.	9 years ago
Mark Adler	44ae761dc2	Clean up portability for shifts and integer sizes.	9 years ago
Mark Adler	e54e129940	Avoid shifts of negative values inflateMark(). The C standard says that bit shifts of negative integers is undefined. This casts to unsigned values to assure a known result.	9 years ago
Mark Adler	0db8fd3714	Fix inflateInit2() bug when windowBits is 16 or 32. A windowBits value of 0, 16, or 32 gets the window bits from the zlib header. However there is no zlib header for 16, or for 32 when the input is gzip. This commit sets the window bits for inflate to 15 if a gzip stream is detected and windowBits was 16 or 32.	10 years ago
Mark Adler	9859a94c10	Remedy Coverity warning. [Randers-Pehrson]	10 years ago
Mark Adler	5370d99a2a	Add inflateCodesUsed() function for internal use.	10 years ago
Mark Adler	62d6112a79	Clean up the usage of z_const and respect const usage within zlib. This patch allows zlib to compile cleanly with the -Wcast-qual gcc warning enabled, but only if ZLIB_CONST is defined, which adds const to next_in and msg in z_stream and in the in_func prototype. A --const option is added to ./configure which adds -DZLIB_CONST to the compile flags, and adds -Wcast-qual to the compile flags when ZLIBGCCWARN is set in the environment.	13 years ago

Mark Adler	70e3b1ca56	Do not set strm->adler when doing raw inflate.	13 years ago
Mark Adler	421c7a61f0	Have inflate() with Z_FINISH avoid the allocation of a window. inflate() avoided that allocation normally, until it was modified to update the window on a normal completion so that inflateResetKeep() could work. This patch restores that behavior, but only when Z_FINISH is used successfully to complete an inflation of a stream in a single call of inflate(). The comments in zlib.h have been updated accordingly.	13 years ago
Mark Adler	afe7cf78d5	Enable dictionary setting in middle of stream, and keeping the dictionary. This patch adds the deflateResetKeep() function to retain the sliding window for the next deflate operation, and fixes an inflateResetKeep() problem that came from inflate() not updating the window when the stream completed. This enables constructing and decompressing a series of concatenated deflate streams where each can depend on the history of uncompressed data that precedes it. This generalizes deflateSetDictionary() and inflateSetDictionary() to permit setting the dictionary in the middle of a stream for raw deflate and inflate. This in combination with the Keep functions enables a scheme for updating files block by block with the transmission of compressed data, where blocks are sent with deflateResetKeep() to retain history for better compression, and deflateSetDictionary() is used for blocks already present at the receiver to skip compression but insert that data in the history, again for better compression. The corresponding inflate calls are done on the receiver side.	13 years ago
Mark Adler	de32a2d749	Remove code from inflate.c and infback.c that is impossible to execute. During coverage testing it was discovered that these two lines could never pull more bits, since the immediately preceding for loop assures that all of the code's bits are already pulled.	13 years ago
Mark Adler	5b48d061c8	Fix indentation of code in inflate.c.	13 years ago
Mark Adler	77b47d55f1	Add undocumented inflateResetKeep() function for CAB file decoding. The Microsoft CAB file format compresses each block with completed deflate streams that depend on the sliding window history of the previous block in order to decode. inflateResetKeep() does what inflateReset() does, except the sliding window history from the previous inflate operation is retained.	13 years ago
Mark Adler	f442c1e89e	Add a ./config --solo option to make zlib subset with no libary use A common request has been the ability to compile zlib to require no other libraries. This --solo option provides that ability. The price is that the gz, compress, and uncompress functions are eliminated, and that the user must provide memory allocation and free routines to deflate and inflate when initializing.	13 years ago
