* 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). ```

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.

2011-11-13Optimize memory allocationRickard Green
A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.

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.

2010-03-16Add function zip:foldl/3 to iterate over zip archivesHåkan Mattsson
This is the public interface of prim_zip:open/3, which has been used in earlier releases by both erl_prim_loader and escript. The new function can be used as a replacement for the undocumented function escript:foldl/3 that is likely to be removed without further notice. The error handling of prim_zip:open/3 (and prim_zip:foldl/3) has been improved in order to better suite a public interface. For example it could happen that a file or a zlib port could be left open in some errors cases. The documentation of the FileSpec parameter to zip:create/3 has been updated to show that file info can be explicitly specified. A FileSpec may contain {Filename, binary(), #file_info{}} elements. The function zip:create/3 was already prepared to partly support this, but now after a few minor fixes it is fully supported.
