6b6475fb56 Prevent ByteToMessageDecoder from overreading when !isAutoRead (#9252)
Motivation:

ByteToMessageDecoder only looks at the last channelRead() in the batch
of channelRead()-s when determining whether or not it should call
ChannelHandlerContext#read() to consume more data when !isAutoRead. This
will lead to read() calls issued unnecessaily and unprompted if the very
last channelRead() didn't result in at least one decoded message, even
if there have been messages decoded from other channelRead()-s in the
current batch.

Modifications:

Track decode outcomes for the entire batch of channelRead() calls and
only issue a read in BTMD if the entire batch of channelRead() calls
yielded no complete messages.

Result:

ByteToMessageDecoder will no longer overread when the very last read
yielded no message, but the batch of reads did.

93414db1f3 Fix LZ4 encoder/decoder performance with (default) xxHash32 (#9249)
Motivation:

Lz4FrameEncoder and Lz4FrameDecoder in their default configuration use
an extremely inefficient way to checksum direct byte buffers. In
particular, for every byte checksummed, a single-element byte array is
being allocated and a JNI cal is made, which in some internal testing
makes a 25x difference in total throughput and allocates *a lot* of
garbage.

Modifications:

Lz4XXHash32, an implementation of ByteBufChecksum specifically for use
by Lz4FrameEncoder and Lz4FrameDecoder, is introduced. It utilises
xxHash32 block API which provides a hash() method that accepts a
ByteBuffer as an argument. Lz4FrameEncoder and Lz4FrameDecoder are
modified to use this implementation by default.

Result:

Lz4FrameEncoder and Lz4FrameDecoder perform well again when operating
on direct byte buffers with default checksum configuration; a public
implementation is provided for those who need to override the seed.

a2583d0d3c Fix ReflectiveByteBufChecksum with direct buffers (#9244)
Motivation:

ReflectiveByteBufChecksum#update(buf, off, len) ignores provided offset
and length arguments when operating on direct buffers, leading to wrong
byte sequences being checksummed and ultimately incorrect checksum
values (unless checksumming the entire buffer).

Modifications:

Use the provided offset and length arguments to get the correct nio
buffer to checksum; add test coverage exercising the four meaningfully
different offset and length combinations.

Result:

Offset and length are respected and a correct checksum gets calculated;
simple unit test should prevent regressions in the future.

a29532df43 Fix ByteBufChecksum optimisation for CRC32 and Adler32 (#9242)
Motivation:

Because of a simple bug in ByteBufChecksum#updateByteBuffer(Checksum),
ReflectiveByteBufChecksum is never used for CRC32 and Adler32, resulting
in direct ByteBuffers being checksummed byte by byte, which is
undesriable.

Modification:

Fix ByteBufChecksum#updateByteBuffer(Checksum) method to pass the
correct argument to Method#invoke(Checksum, ByteBuffer).

Result:

ReflectiveByteBufChecksum will now be used for Adler32 and CRC32 on
Java8+ and direct ByteBuffers will no longer be checksummed on slow
byte-by-byte basis.

Allow null sender when using DatagramPacketEncoder (#9204)
Motivation:

It is valid to use null as sender so we should support it when DatagramPacketEncoder checks if it supports the message.

Modifications:

- Add null check
- Add unit test

Result:

ByteToMessageDecoder.handlerRemoved(...) should only call fireChannelReadComplete() if fireChannelRead(...) was called before (#9211)
Motivation:

At the moment ByteToMessageDecoder always calls fireChannelReadComplete() when the handler is removed from the pipeline and the cumulation buffer is not null. We should only call it when we also call fireChannelRead(...), which only happens if the cumulation buffer is not null and readable.

Modifications:

Only call fireChannelReadComplete() if fireChannelRead(...) is called before during removal of the handler.

Result:

More correct semantics

2ca526fac6 Ensure "full" ownership of msgs passed to EmbeddedChannel.writeInbound() (#9058)
Motivation

Pipeline handlers are free to "take control" of input buffers if they have singular refcount - in particular to mutate their raw data if non-readonly via discarding of read bytes, etc.

However there are various places (primarily unit tests) where a wrapped byte-array buffer is passed in and the wrapped array is assumed not to change (used after the wrapped buffer is passed to EmbeddedChannel.writeInbound()). This invalid assumption could result in unexpected errors, such as those exposed by #8931.

Modifications

Anywhere that the data passed to writeInbound() might be used again, ensure that either:
- A copy is used rather than wrapping a shared byte array, or
- The buffer is otherwise protected from modification by making it read-only

For the tests, copying is preferred since it still allows the "mutating" optimizations to be exercised.

Results

Avoid possible errors when pipeline assumes it has full control of input buffer.

Only use static Exception instances when we can ensure addSuppressed … (#9152)
Motivation:

OOME is occurred by increasing suppressedExceptions because other libraries call Throwable#addSuppressed. As we have no control over what other libraries do we need to ensure this can not lead to OOME.

Modifications:

Only use static instances of the Exceptions if we can either dissable addSuppressed or we run on java6.

Result:

Not possible to OOME because of addSuppressed. Fixes https://github.com/netty/netty/issues/9151.

DefaultHeaders#valueIterator doesn't remove from the in bucket list (#9090)
Motivation:
DefaultHeaders entries maintains two linked lists. 1 for overall insertion order
and 1 for "in bucket" order. DefaultHeaders#valueIterator removal (introduced in 1d9090aab2) only reliably
removes the entry from the overall insertion order, but may not remove from the
bucket unless the element is the first entry.

Modifications:
- DefaultHeaders$ValueIterator should track 2 elements behind the next entry so
that the single linked "in bucket" list can be patched up when removing the
previous entry.

Result:
More correct DefaultHeaders#valueIterator removal.

1d9090aab2 DefaultHeaders#valueIterator to support removal (#9063)
Motivation:
While iterating values it is often desirable to be able to remove individual
entries. The existing mechanism to do this involves removal of all entries and
conditional re-insertion which is heavy weight in order to remove a single
value.

Modifications:
- DefaultHeaders$ValueIterator supports removal

Result:
It is possible to remove entries while iterating the values in DefaultHeaders.

Correctly discard messages after oversized message is detected. (#9015)
Motivation:

32563bfcc1 introduced a regression in which we did now not longer discard the messages after we handled an oversized message.

Modifications:

- Do not set aggregating to false after handleOversizedMessage is called
- Adjust unit tests to verify the behaviour is correct again.

Tighten up contract of PromiseCombiner and so make it more safe to use (#8886)
Motivation:

PromiseCombiner is not thread-safe and even assumes all added Futures are using the same EventExecutor. This is kind of fragile as we do not enforce this. We need to enforce this contract to ensure it's safe to use and easy to spot concurrency problems.

Modifications:

- Add new contructor to PromiseCombiner that takes an EventExecutor and deprecate the old non-arg constructor.
- Check if methods are called from within the EventExecutor thread and if not fail
- Correctly dispatch on the right EventExecutor if the Future uses a different EventExecutor to eliminate concurrency issues.

Result:

More safe use of PromiseCombiner + enforce correct usage / contract.

b72fea340b Improve DateFormatter parsing performance (#8821)
Motivation:

Just was looking through code and found 1 interesting place DateFormatter.tryParseMonth that was not very effective, so I decided to optimize it a bit.

Modification:

Changed DateFormatter.tryParseMonth method. Instead of invocation regionMatch() for every month - compare chars one by one.

Result:

DateFormatter.parseHttpDate method performance improved from ~3% to ~15%.

32563bfcc1 Selective Message Aggregation (#8793)
Motivation

Implementations of MessageAggregator (HttpObjectAggregator in particular) may wish to
selectively aggrerage requests and responses on a case-by-case basis such as for example
only POST requests or only responses of a certain content-type.

Modifications

Adding a flag to MessageAggregator that toggles between true/false depending on if aggregation
is desired for the current message or not.

e2d9665707 Added comments to LineBasedFrameDecoder, JsonObjectDecoder and XmlFrameDecoder that they are only compatible with UTF-8 encoded streams. (#8651)
Motivation:

LineBasedFrameDecoder, JsonObjectDecoder and XmlFrameDecoder upon investigation of the
sourcecode appeared to only support ASCII or UTF-8 input. It is an important characteristic
and ont reflected in any documentation. This could lead to improper usage and bugs.

Modifications:

Javadoc comment is addedd to all three classes to state that implementation is only
compatible with UTF-8 or ASCII input streams and brifly touches on implementaion details.

Result:

The end user of the netty library would not have to study sorcecode to deterime character
encoding limitations for given classes.

6563f23a9b Don't swallow intermediate write failures in MessageToMessageEncoder (#8454)
Motivation:

If the encoder needs to flush more than one outbound message it will
create a new ChannelPromise for all but the last write which will
swallow failures.

Modification:

Use a PromiseCombiner in the case of multiple messages and the parent
promise isn't the `VoidPromise`.

Result:

Intermediate failures are propagated to the original ChannelPromise.

d7fa7be67f Exploit PlatformDependent.allocateUninitializedArray() in more places (#8393)
Motivation:

There are currently many more places where this could be used which were
possibly not considered when the method was added.

If https://github.com/netty/netty/pull/8388 is included in its current
form, a number of these places could additionally make use of the same
BYTE_ARRAYS threadlocal.

There's also a couple of adjacent places where an optimistically-pooled
heap buffer is used for temp byte storage which could use the
threadlocal too in preference to allocating a temp heap bytebuf wrapper.
For example
https://github.com/netty/netty/blob/4.1/buffer/src/main/java/io/netty/buffer/ByteBufUtil.java#L1417.

Modifications:

Replace new byte[] with PlatformDependent.allocateUninitializedArray()
where appropriate; make use of ByteBufUtil.getBytes() in some places
which currently perform the equivalent logic, including avoiding copy of
backing array if possible (although would be rare).

Result:

Further potential speed-up with java9+ and appropriate compile flags.
Many of these places could be on latency-sensitive code paths.

583d838f7c Optimize AbstractByteBuf.getCharSequence() in US_ASCII case (#8392)
* Optimize AbstractByteBuf.getCharSequence() in US_ASCII case

Motivation:

Inspired by https://github.com/netty/netty/pull/8388, I noticed this
simple optimization to avoid char[] allocation (also suggested in a TODO
here).

Modifications:

Return an AsciiString from AbstractByteBuf.getCharSequence() if
requested charset is US_ASCII or ISO_8859_1 (latter thanks to
@Scottmitch's suggestion). Also tweak unit tests not to require Strings
and include a new benchmark to demonstrate the speedup.

Result:

Speed-up of AbstractByteBuf.getCharSequence() in ascii and iso 8859/1

c58069f284 Better handling of streaming JSON data in JsonObjectDecoder (#7821)
Motivation:

When the JsonObjectDecoder determines that the incoming buffer had some data discarded, it resets the internal index to readerIndex and attempts to adjust the state which does not correctly work for streams of JSON objects.

Modifications:

Reset the internal index to the value considering the previous reads.

Result:

JsonObjectDecoder correctly handles streams of both JSON objects and arrays with no state adjustments or repeatable reads.

f40ecc3f10 Fix Snappy decoding of large 2-byte literal lengths and copy offsets
Motivation:

The Snappy decoder was failing on valid inputs containing literals
with 2-byte lengths > 0x8000 or copies with 2-byte offsets >= 0x8000.

The decoder was also enforcing an artificially low offset limit of
0x7FFF, something the Snappy format description advises against,
and which prevents decoding valid inputs generated by other encoders.

Modifications:

Interpret 2-byte literal lengths and 2-byte copy offsets as unsigned
shorts, in accordance with the format description and reference
implementation.

Allow any positive offset value. Throw an appropriate exception
for negative values (which can theoretically occur due to arithmetic
overflow on 4-byte offsets, but are unlikely to occur in the wild).

Result:

The Snappy decoder can handle valid inputs that previously caused
it to throw exceptions.

1e5fafe446 Simplify CharSequenceValueConverter#convertToBoolean
Motivation:
CharSequenceValueConverter#convertToBoolean has a few manual conditionals which can be removed if we use AsciiString.contentEqualsIgnoreCase. Also by comparing an AsciiString to a String we will incur conversions to char that can be avoided if we compare against AsciiString.

Modifications:
- Use AsciiString.contentEqualsIgnoreCase
- Compare against a AsciiString

c1d0d88f0a Implement DefaultHeaders.HeaderEntry.equals()
Motivation:

HeaderEntry.equals() inherets Object.equals() which simply check if two objects are the same.
So it returns false even when two HeaderEntry objects have the same name and value.

Modifications:

Implement HeaderEntry.equals() that follows the specification of Map.Entry.equals().
https://docs.oracle.com/javase/9/docs/api/java/util/Map.Entry.html#equals-java.lang.Object-

Result:

HeaderEntry.equals() returns true if two HeaderEntry objects have the same name and value.

6ff48dcbe3 Fixes #7566 by handling concatenated GZIP streams.
Motivation:
According to RFC 1952, concatenation of valid gzip streams is also a valid gzip stream. JdkZlibDecoder only processed the first and discarded the rest.

Modifications:
- Introduced a constructor argument decompressConcatenated that if true, JdkZlibDecoder would continue to process the stream.

Result:
- If 'decompressConcatenated = true', concatenated streams would be processed in
compliance to RFC 1952.
- If 'decompressConcatenated = false' (default), existing behavior would remain.

- Only use validation if the original headers used validation as well.
- Ensure we create a copy of the headers in replace(...).

Motivation:

DefaultHttpHeader.names() exposes HTTP header names as a Set<String>. Converting the resulting set to an array using toArray(String[]) throws an exception: java.lang.ArrayStoreException: io.netty.util.AsciiString.

Modifications:

- Remove our custom implementation of toArray(...) (and others) by just extending AbstractCollection.

Motivation:

For debugging/logging purpose, it would be convenient to have
HttpHeaders#toString implemented.

DefaultHeaders does implement toString be the implementation is suboptimal and allocates a Set for the names and Lists for values.

Modification:

* Introduce HeadersUtil#toString that provides a convenient optimized helper to implement toString for various headers implementations
* Have DefaultHeaders#toString and HttpHeaders#toString delegate their toString implementation to HeadersUtil

Result:

Convenient HttpHeaders#toString. Optimized DefaultHeaders#toString.

93130b172a HttpObjectEncoder and MessageAggregator EMPTY_BUFFER usage
Motivation:
HttpObjectEncoder and MessageAggregator treat buffers that are not readable special. If a buffer is not readable, then an EMPTY_BUFFER is written and the actual buffer is ignored. If the buffer has already been released then this will not be correct as the promise will be completed, but in reality the original content shouldn't have resulted in any write because it was invalid.

Modifications:
- HttpObjectEncoder should retain/write the original buffer instead of using EMPTY_BUFFER
- MessageAggregator should retain/write the original ByteBufHolder instead of using EMPTY_BUFFER

Result:
Invalid write operations which happen to not be readable correctly reflect failed status in the promise, and do not result in any writes to the channel.

50a067a8f7 Make methods 'static' where it possible
Motivation:

Even if it's a super micro-optimization (most JVM could optimize such
 cases in runtime), in theory (and according to some perf tests) it
 may help a bit. It also makes a code more clear and allows you to
 access such methods in the test scope directly, without instance of
 the class.

Modifications:

Add 'static' modifier for all methods, where it possible. Mostly in
test scope.

Result:

Cleaner code with proper 'static' modifiers.

3fe1f71511 Do not treat errors as decoder exception (redux)
Motivation: Today when Netty encounters a general error while decoding
it treats this as a decoder exception. However, for fatal causes this
should not be treated as such, instead the fatal error should be carried
up the stack without the callee having to unwind causes. This was
probably done for byte to byte message decoder but is now done for all
decoders.

Modifications: Instead of translating any error to a decoder exception,
we let those unwind out the stack (note that finally blocks still
execute) except in places where an event needs to fire where we fire
with the error instead of wrapping in a decoder exception.

Result: Fatal errors will not be treated as innocent decoder exceptions.

80b8a91b70 Use offset finding eol avoid repeated scaning.
Motivation:

A large frame will be componsed by many packages. Every time the package
arrived, findEndOfLine will be called from the start of the buffer. It
will cause the complexity of reading frame equal to  O(n^2). This can be
eliminated by using a offset to mark the last scan position, when new
package arrived, just find the delimter from the mark. The complexity
will be O(n).

Modification:

Add a offset to mark the last scan position.

Result:

Better performance for read large frame.

6780183a89 Makes LengthFieldBasedFrameDecoder::decode inlineable
Motivation:

The decode method is too large to be inlined with default compiler settings, hence the uncommon paths need to be packed and moved away form the common one.

Modifications:

The uncommon paths of the decode call (eg failures with thrown exceptions) are packed and moved in private methods in order to reduce the size of the common one
and let it being inlined.

Result:

The decode method is being inlined if the stack depth allows it.

db4781282f Handle partially decoded elements while streaming Json array
Motivation:

'insideString' and 'openBraces' need a proper handling when streaming
Json array over multiple writes and an element decoding was started but
not completed.
Related to #6969

Modifications:

If the idx is reset:
- 'insideString' has to be reset to 'false' in order to indicate that
  array element will be decoded from the beginning
- 'openBraces' has to be reset to '1' to indicate that Json array
  decoding is in progress.

6ab9c177ac Fix hash function and hash table size in Snappy
Motivation:

1. Hash function in the Snappy encoding is wrong probably: used '+' instead of '*'. See the reference implementation [1].
2. Size of the hash table is calculated, but not applied.

Modifications:

1. Fix hash function: replace addition by multiplication.
2. Allocate hash table with calculated size.
3. Use an `Integer.numberOfLeadingZeros` trick for calculate log2.
4. Release buffers in tests.

Result:

1. Better compression. In the test `encodeAndDecodeLongTextUsesCopy` now compressed size is 175 instead of 180 before this change.
2. No redundant allocations for hash table.
3. A bit faster the calc of shift (less an expensive math operations).

Motivation:

1. `ByteBuf` contains methods to writing `CharSequence` which optimized for UTF-8 and ASCII encodings. We can also apply optimization for ISO-8859-1.
2. In many places appropriate methods are not used.

Modifications:

1. Apply optimization for ISO-8859-1 encoding in the `ByteBuf#setCharSequence` realizations.
2. Apply appropriate methods for writing `CharSequences` into buffers.

14ea69cdc1 NullPointerException in Lz4FrameEncoder
Motivation:
Lz4FrameEncoder maintains internal state, but the life cycle of the buffer is not consistently managed. The buffer is allocated in handlerAdded but freed in close, but the buffer can still be used until handlerRemoved is called.

Modifications:
- Move the cleanup of the buffer from close to handlerRemoved
- Explicitly throw an EncoderException from Lz4FrameEncoder if the encode operation has finished and there isn't enough space to write data

Result:
No more NPE in Lz4FrameEncoder on the buffer.

Motivation:
ByteToMessageDecoder#handlerRemoved will immediately release the cumulation buffer, but it is possible that a child class may still be using this buffer, and therefore use a dereferenced buffer.

Modifications:
- ByteToMessageDecoder#handlerRemoved and ByteToMessageDecoder#decode should coordinate to avoid the case where a child class is using the cumulation buffer but ByteToMessageDecoder releases that buffer.

Result:
Child classes of ByteToMessageDecoder are less likely to reference a released buffer.

38b054c65c Correctly handle read-only ByteBuf in ByteToMessageDecoder
Motivation:

If a read-only ByteBuf is passed to the ByteToMessageDecoder.channelRead(...) method we need to make a copy of it once we try to merge buffers for cumulation. This usually is not the case but can for example happen if the local transport is used. This was the cause of the leak report we sometimes saw during the codec-http2 tests, as we are using the local transport and write a read-only buffer. This buffer will then be passed to the peer channel and fired through the pipeline and so end up as the cumulation buffer in the ByteToMessageDecoder. Once the next fragement is received we tried to merge these and failed with a ReadOnlyBufferException which then produced a leak.

Modifications:

Ensure we copy the buffer if its read-only.

Result:

No more exceptions and so leak when a read-only buffer is passed to ByteToMessageDecoder.channelRead(...)

77e65fe6bb Base64 reduce byte manipulation operations
Motivation:
Base64#decode4to3 generally calculates an int value where the contents of the decodabet straddle bytes, and then uses a byte shifting or a full byte swapping operation to get the resulting contents. We can directly calculate the contents and avoid any intermediate int values and full byte swap operations. This will reduce the number of operations required during the decode operation.

Modifications:
- remove the intermediate int in the Base64#decond4to3 method.
- manually do the byte shifting since we are already doing bit/byte manipulations here anyways.

Result:
Base64#decode4to3 requires less operations to compute the end result.

7feb92959e Improve performance of Base64.decode and encode methods.
Motivation:

The decode and encode method uses getByte(...) and setByte(...) in loops which can be very expensive because of bounds / reference-count checking. Beside this it also slows-down a lot when paranoid leak-detection is enabled as it will track each access.

Modifications:

- Pack bytes into int / short and so reduce operations on the ByteBuf
- Use ByteProcessor to reduce getByte calls.

Result:

Better performance in general. Also when you run the build with -Pleak the handler module will build in 1/4 of the time it took before.

9b2b3e2512 Ensure tests pass when sun.misc.Unsafe is not present
Motivation:

We need to ensure we pass all tests when sun.misc.Unsafe is not present.

Modifications:

- Make *ByteBufAllocatorTest work whenever sun.misc.Unsafe is present or not
- Let Lz4FrameEncoderTest not depend on AbstractByteBufAllocator implementation details which take into account if sun.misc.Unsafe is present or not

Result:

Tests pass even without sun.misc.Unsafe.

3344cd21ac Wrap operations requiring SocketPermission with doPrivileged blocks
Motivation:

Currently Netty does not wrap socket connect, bind, or accept
operations in doPrivileged blocks. Nor does it wrap cases where a dns
lookup might happen.

This prevents an application utilizing the SecurityManager from
isolating SocketPermissions to Netty.

Modifications:

I have introduced a class (SocketUtils) that wraps operations
requiring SocketPermissions in doPrivileged blocks.

Result:

A user of Netty can grant SocketPermissions explicitly to the Netty
jar, without granting it to the rest of their application.
