* john/erts/fix-gunzip-eos/OTP-14730/ERL-507: Only apply EOS behaviors if there's pending data
2017-11-09Avoid WindowBits=8 as per the manualJohn Högberg
The docs for zlib:deflateInit/6 explicitly mention that 8 is broken and should not be used unless we know for certain that our zlib version supports it.
2017-11-09Fix deflateParams on zlib 1.2.11John Högberg
1.2.11 started bailing when avail_out==0 regardless of whether there's anything to flush or not, and there's no point in adapting the old method since it was vulnerable to bugs in other zlib versions which updated the deflate parameters even on failure. The api_deflateParams test has been expanded accordingly, and two white-box cases in zip_usage has been updated to make fewer assumptions about the output; the validity of the compressed data is what matters, not whether it's exactly the same as the test vector.

2017-09-29Fix gunzip/1 of concatenated gzip filesJohn Högberg
Quoting RFC 1952: "A gzip file consists of a series of "members" (compressed data sets). [...] The members simply appear one after another in the file, with no additional information before, between, or after them."
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.

2017-09-05Replace 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.

* 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.

2011-08-16emulator: 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.
