2017-09-29Fix minor incompatibilities in inflate behaviorJohn Högberg
When presented with multiple valid but concatenated streams, the old driver returned an empty result once the end of the first stream was reached, and kept doing so even if fed new data. The new driver/NIF returned a data_error instead. zlib:inflateInit/3 has been added to control this behavior, but is not yet ready for public use.
2017-09-05Improve zlib error messages and update test suite to fitJohn Högberg
OTP-14527
2017-09-05Replace the zlib driver with a NIFJohn Högberg
All operations will now yield appropriately, allowing them to be used freely in concurrent applications. This commit also deprecates the functions listed below, although they won't raise deprecation warnings until OTP 21: zlib:adler32 zlib:crc32 zlib:inflateChunk zlib:getBufSize zlib:setBufSize The behavior of throwing an error when a dictionary is required for decompression has also been deprecated.

2017-02-17Teach make_preload to handle the new 'AtU8' chunkBjörn Gustavsson
26b59dfe67 introduced the new 'AtU8' chunk to support Unicode atoms. make_preload strips the pre-loaded BEAM files so that they only contain essential chunks. It expects to find the old 'Atom' chunk. Teach make_preload to read the new 'AtU8' chunk instead of the old chunk. Also produce a nice error message if someone by mistake compiles the pre-loaded modules with an OTP 19 compiler.

* seriyps/zlib-inflate-bound: Add zlib limited output buffer size functionality Conflicts: erts/preloaded/ebin/zlib.beam OTP-12548
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). ```
