Trevor Norris	3a2f273bd7	buffer: use smalloc as backing data store Memory allocations are now done through smalloc. The Buffer cc class has been removed completely, but for backwards compatibility have left the namespace as Buffer. The .parent attribute is only set if the Buffer is a slice of an allocation. Which is then set to the alloc object (not a Buffer). The .offset attribute is now a ReadOnly set to 0, for backwards compatibility. I'd like to remove it in the future (pre v1.0). A few alterations have been made to how arguments are either coerced or thrown. All primitives will now be coerced to their respective values, and (most) all out of range index requests will throw. The indexes that are coerced were left for backwards compatibility. For example: Buffer slice operates more like Array slice, and coerces instead of throwing out of range indexes. This may change in the future. The reason for wanting to throw for out of range indexes is because giving js access to raw memory has high potential risk. To mitigate that it's easier to make sure the developer is always quickly alerted to the fact that their code is attempting to access beyond memory bounds. Because SlowBuffer will be deprecated, and simply returns a new Buffer instance, all tests on SlowBuffer have been removed. Heapdumps will now show usage under "smalloc" instead of "Buffer". ParseArrayIndex was added to node_internals to support proper uint argument checking/coercion for external array data indexes. SlabAllocator had to be updated since handle_ no longer exists.	12 years ago

Trevor Norris	e92f4879eb	string_bytes: write strings using new API StringBytes::Write now uses new v8 API and also does preliminary check if the string is external, then will use external memory instead.	12 years ago
Trevor Norris	642ea2b668	string_bytes: use external for large strings When large strings are used they cause v8's GC to spend a lot more time cleaning up. In these cases it's much faster to use external string resources. UTF8 strings do not use external string resources because only one and two byte external strings are supported. EXTERN_APEX is the value at which v8's GC overtakes performance. The following table has the type and buffer size that use to encode the strings as rough estimates of the percentage of performance gain from this patch (UTF8 is missing because they cannot be externalized). encoding 128KB 1MB 5MB ----------------------------- ASCII 58% 208% 250% HEX 15% 74% 86% BASE64 11% 74% 71% UCS2 2% 225% 398% BINARY 2234% 1728% 2305% BINARY is so much faster across the board because of using the new v8 WriteOneByte API.	12 years ago
Trevor Norris	87624ab911	string_bytes: implement new v8 API v8 has a new API to write out strings to memory. This has been implemented. One other change of note is BINARY encoded strings have a new implementation. This has improved performance substantially.	12 years ago
Trevor Norris	45a08cb216	lint: add mising isolates and minor style fixes	12 years ago
Trevor Norris	d5d5170c35	string_bytes: strip padding from base64 strings Because of variations in different base64 implementation, it's been decided to strip all padding from the end of a base64 string and calculate its size from that.	12 years ago
isaacs	f57ff787aa	src: Remove superfluous static_cast	12 years ago
Ben Noordhuis	f59ab10a64	buffer, crypto: fix default encoding regression The default encoding is 'buffer'. When the input is a string, treat it as 'binary'. Fixes the following assertion: node: ../src/string_bytes.cc:309: static size_t node::StringBytes::StorageSize(v8::Handle<v8::Value>, node::encoding): Assertion `0 && "buffer encoding specified but string provided"' failed. Introduced in `64fc34b2`. Fixes #5482.	12 years ago
isaacs	64fc34b270	src: Add StringBytes static util class Four functions: - StringBytes::StorageSize() - StringBytes::Size() - StringBytes::Write() - StringBytes::Encode()	12 years ago
