* essen/zlib-windowbits: Update zlib:zwindowbits/0 type to accept 8 and -8 OTP-12564
2015-03-03Update zlib:zwindowbits/0 type to accept 8 and -8Loïc Hoguin
Commit 7e8f5a776cbfa376e03369d058a90c8dd9f217fc (importing R11B-3) updated zlib, which had changed what values it accepts for window bits from 9-15 to 8-15. From deflate.c: - windowBits < 9 || windowBits > 15 || level < 0 || level > 9 || - strategy < 0 || strategy > Z_HUFFMAN_ONLY) { + windowBits < 8 || windowBits > 15 || level < 0 || level > 9 || + strategy < 0 || strategy > Z_FIXED) { return Z_STREAM_ERROR; } + if (windowBits == 8) windowBits = 9; /* until 256-byte window bug fixed */ In inflate.c 8 was already an accepted value. This commit updates OTP to also accept the values 8 and -8.
2015-02-12Add zlib limited output buffer size functionalityСергей Прохоров
This functionality may be useful for compressed streams with high compression ratio (in case of gzip it may be up to x1000), when small amount of compressed data will produce large amount of uncompressed output. This may lead to DoS attacks, because server easily goes out of memory. Example of such high compression ratio stream: ``` dd if=/dev/zero of=sparse.bin bs=1MB count=100 # 100mb of zeroes gzip sparse.bin # 95kb sparse.bin.gz $ erl > {ok, Compressed} = file:read_file("sparse.bin.gz"), > 97082 = size(Compressed), > Uncompressed = zlib:gunzip(Compressed), > 100000000 = iolist_size(Uncompressed). ```

2012-03-15Fix port leaks in zlibSverker Eriksson
zip,unzip,gzip,gunzip,compress and uncompress did not close the port when given invalid data argument. Fixed by putting close in "try-after". A closed port could in same cases get stuck in limbo due to data in io-queue. Fixed by adding a flush callback.

2011-09-02Update documentation and specifications of some of the zlib functionsHans Bolinder
The functions zlib:deflateSetDictionary/2 and zlib:inflateSetDictionary/2 accept iodata() as Dictionary. The functions zlib:crc32/2,3, zlib:adler32/2,3, zlib:compress/1, zlib:uncompress/1, zlib:zip/1, and zlib:unzip/1 accept iodata() as data.
2011-08-16emulator: Add a fourth element in exception stacktracesBjörn Gustavsson
This commit is a preparation for introducing location information (filename/line number) in stacktraces in exceptions. Currently a stack trace looks like: [{Mod1,Function1,Arity1}, . . . {ModN,FunctionN,ArityN}] Add a forth element to each tuple that can be used indication the filename and line number of the source file: [{Mod1,Function1,Arity1,Location1}, . . . {ModN,FunctionN,ArityN,LocationN}] In this commit, the fourth element will just be an empty list, and we will change all code that look at or manipulate stacktraces.
