Bryan O'Sullivan reported that on- his 64-bit system with GHC 7.0.3 the 'text' library is 5x faster than the- 'blaze-builder' library.--* 0.3.0.0-- - Renamings in internal modules: WriteIO -> Poke and associated functions.--* 0.2.1.4-- - Fixed bug: appending to 'chunkedTransferEncoding somebuilder' also encoded- the appended builder, which is obviously wrong.--* 0.2.1.3-- - Fixed bug: 'chunkedTransferTerminator' is now correctly set to "0\r\n\r\n".--* 0.2.1.2-- - Add 'MonoPatBinds' language extension to all relevant files to solve the- issues caused by GHC bug http://hackage.haskell.org/trac/ghc/ticket/4498--* 0.2.1.1-- - Reexport 'Write' datatype and 'fromWriteList', 'fromWriteSingleton',- 'fromWrite' functions together with writes and builders for storables.- - Add 'MonoPatBinds' language extension to (hopefully) solve the issues- caused by GHC bug http://hackage.haskell.org/trac/ghc/ticket/4498--* 0.2.1.0-- Incorporated several design changes:- - Writable buffer range is now represented in a packed form. This improves- speed slightly, as less currying is used.- - Writes are abstracted such that their internal representation can be- exchanged without breaking other library code.- - Writes are represented in a form that allows for efficient monoid- instances for branching code like UTF-8 encoding. For single character- encoding this results currently in a slight slowdown due to GHC not- recognizing the strictness of the returned value. This will be fixed in- the future.- - BuildSteps support returning a result in `Done`, which enables to- implement a `Put` monad using CPS.- - chunked list writes were removed, as they result in worse performance- when writing non-trivial lists. (cf. benchmarks)- - An internal buffering abstraction is introduced, which is used both- by the adaption of the `binary` package, as well as by the- `blaze-builder-enumeratee` package, to execute puts and builders.- It will be used later also by the execution functions of the- `blaze-builder` package.-- Implemented new functionality- - `Blaze.ByteString.Builder.HTTP` provides a builder transformer for- doing in-buffer chunked HTTP encoding of an arbitary other builder.- - `Blaze.ByteString.Builder.Char8` provides functions to serialize the- lower 8-bits of characters similiar to what `Data.ByteString.Char8`- provides for bytestrings.--* 0.2.0.3-- Loosen 'text' dependency to '>= 0.10 && < 0.12'--* 0.2.0.2-- Fixed bug: use ' instead of ' for HTML escaping '--* 0.2.0.1-- Added a missing benchmark file.--* blaze-builder-0.2.0.0-- Heavily restructured 'blaze-builder' such that 'Blaze.ByteString.Builder' serves as- a drop-in replacement of 'binary:Data.Binary.Builder' which it improves upon- with respect to both speed as well as expressivity. See the documentation and- the benchmarks for details on improvements and new functionality.-- Changed module structure:- Blaze.ByteString.Builder.Core -> Blaze.ByteString.Builder- Blaze.ByteString.Builder.Utf8 -> Blaze.ByteString.Builder.Char.Utf8- Blaze.ByteString.Builder.Html -> Blaze.ByteString.Builder.Html.Utf8-- Changed function names:- writeByte -> writeWord8- fromByte -> fromWord8- fromWriteList -> fromWrite1List-- Possibly performance sensitive implementation changes:- - 'fromByteString' and 'fromLazyByteString' check now if a direct insertion- of the bytestring(s) would be cheaper than copying it. See their- documentation on how to recover the old behaviour.-- Deprecated functions:- 'empty' : use 'mempty' instead- 'singleton': use 'fromWord8' instead- 'append' : use 'mappend' instead---* blaze-builder-0.1-- This is the first version of 'blaze-builder'. It is explicitely targeted at- fast generation of UTF-8 encoded HTML documents in the 'blaze-html' and the- 'hamlet' HTML templating libraries.

UPDATE BENCHMARKS !!- - * custom serialization functions for lists of 'WordX's- - benchmark chunk size speedup for more complicated computations of list- elements => to be expected that we get no speedup anymore or even a- slowdown => adapt Blaze.ByteString.Builder.Word accordingly.-- * fast serialization for 'Text' values (currently unpacking to 'String' is- the fastest :-/)-- * implementation- - further encodings for 'Char'- - think about end-of-buffer wrapping when copying bytestrings- - toByteStringIO with accumulator capability => provide 'toByteStringIO_'- - allow buildr/foldr deforestation to happen for input to 'fromWrite<n>List'- (or whatever stream fusion framework is in place for lists)- - implement 'toByteString' with an amortized O(n) runtime using the- exponentional scaling trick. If the start size is chosen wisely this- may even be faster than 'S.pack', as the one copy per element is- cheaper than one list thunk per element. It is even likely that we can- amortize three copies per element, which allows to avoid spilling any- buffer space by doing a last compaction copy.- - we could provide builders that honor alignment restrictions, either as- builder transformers or as specialized write to builder converters. The- trick is for the driver to ensure that the buffer beginning is aligned- to the largest aligning (8 or 16 bytes?) required. This is probably the- case by default. Then we can always align a pointer in the buffer by - appropriately aligning the write pointer.-- * extend tests to new functions-- * benchmarks- - understand why the declarative blaze-builder version is the fastest- serializer for Word64 little-endian and big-endian - - check the cost of using `mappend` on builders instead of writes.- - show that using toByteStringIO has an advantage over toLazyByteString- - check performance of toByteStringIO- - compare speed of 'L.pack' to speed of 'toLazyByteString . fromWord8s'-- * documentation- - sort out formultion: "serialization" vs. "encoding"-- * check portability to Hugs-- * performance:- - check if reordering 'pe' and 'pf' change performance; it seems that 'pe'- is only a reader argument while 'pf' is a state argument.- - perhaps we could improve performance by taking page size, page- alignment, and memory access alignment into account.- - detect machine endianness and use host order writes for the supported- endianness.- - introduce a type 'BoundedWrite' that encapsulates a 'Write' generator- with a bound on the number of bytes maximally written by the write.- This way we can achieve data independence for the size check by- sacrificing just a little bit of buffer space at buffer ends.- - investigate where we would profit from static bounds on number of bytes- written (e.g. to make the control flow more linear)-- * testing- - port tests from 'Data.Binary.Builder' to ensure that the word writes- and builders are working correctly. I may have missed some pitfalls- about word types in Haskell during porting the functions from- 'Data.Binary.Builder'.-- * portability- - port to Hugs- - test lower versions of GHC-- * deployment- - add source repository to 'blaze-html' and 'blaze-builder' cabal files

Description:- This library provides an implementation of the older- blaze-builder interface in terms of the new builder that- shipped with bytestring-0.10.4.0- .- This implementation is mostly intended as a bridge to the- new builder, so that code that uses the old interface- can interoperate with code that uses the new- implementation. Note that no attempt has been made- to preserve the old internal modules, so code that- has these dependencies cannot use this interface.- .- New code should, for the most part, use the new- interface. However, this module does implement- a chunked HTTP encoding, which is not otherwise- implemented (yet?) with the new builder.+ This library allows to efficiently serialize Haskell values to lazy bytestrings+ with a large average chunk size. The large average chunk size allows to make+ good use of cache prefetching in later processing steps (e.g. compression) and+ reduces the system call overhead when writing the resulting lazy bytestring to a+ file or sending it over the network.+ .+ This library was inspired by the module Data.Binary.Builder provided by the+ binary package. It was originally developed with the specific needs of the+ blaze-html package in mind. Since then it has been restructured to serve as a+ drop-in replacement for Data.Binary.Builder, which it improves upon both in+ speed as well as expressivity.
