This commit introduces computeAttribute() as an interface default method
in the AttributeAccessor API. This serves as a convenience analogous to
the computeIfAbsent() method in java.util.Map.
Closes gh-26281
HttpMessageWriter implementations now attach the request log prefix
as a hint to created data buffers when the logger associated with
the writer is at DEBUG level.
Closes gh-26230
The previous implementation uses ArrayList for storing resolved
resources and ArrayList has O(n) time complexity for the contains
operation. By switching to the HashSet for storing resolved
resources we improve the time complexity of this operation to be O(1).
See gh-25927
There are more locations which could benefit from not using a
toCharArray on a String, but rather use the charAt method from
the String itself. This to prevent an additional copy of the
char[] being created.
This commit introduces `and()` default methods in the MethodFilter and
FieldFilter functional interfaces in ReflectionUtils in order to simplify
uses cases that need to compose filter logic.
Closes gh-26063
Prior to this commit, MergedAnnotationCollectors.toAnnotationSet()
created an intermediate ArrayList for storing the results prior to
creating a LinkedHashSet in the finishing step.
Since the creation of the intermediate list is unnecessary, this commit
simplifies the implementation of toAnnotationSet() by using the
Collector.of() factory method that does not accept a `finisher` argument.
The resulting Collector internally uses a `castingIdentity()` function
as the `finisher`.
Closes gh-26031
The migration from JUnit 4 assertions to AssertJ assertions resulted in
several unnecessary casts from int to long that actually cause
assertions to pass when they should otherwise fail.
This commit fixes all such bugs for the pattern `.isNotEqualTo((long)`.
The existing implementation was exposed to very poor performance when matching
with multiple delimiters against a large buffer with many delimiters. In that
case all matchers are invoked many times (as many as the number of delimiters)
even though some of them found no match at all on the first pass.
The revised implementation uses a single index and advances all matchers
together, checking one byte a time, and not letting any one of them search to
the end of the entire buffer on a single pass.
Closes gh-25915
Simplify and optimize the processing of the input stream.
The existing implementation was using bufferUntil and creating a List
for every line along with an EndFrameBuffer inserted for the
bufferUntil predicate. So the larger the input buffer and the more
lines it contained, the greater the overhead.
The new implementation avoids bufferUntil for all lines and
instead uses concatMapIterable to aggregate the lines from a buffer
into a single list. So the larger the input buffer and the more
lines it contains, the better the throughput. The only buffering
used then is for partial chunks and those are accumulated in a list.
See gh-25915
Before this commit, ReadCompletionHandler delayed closing the channel
to allow an ongoing read to complete/fail so we can get a hold of the
associated DataBuffer and release it. This can be problematic since the
read take time to complete but even more importantly there was a race
condition where we didn't check if we've been disposed concurrently
while releasing the read flag.
This commit removes the delay and closes the channel immediately from
cancel() and that should in turn fail any ongoing read operation,
according to AsynchronousChannel, and the DataBuffer is released.
Further improvements include:
- combining the "reading" and "disposed" AtomicBoolean's into a
single "state" AtomicReference.
- an optimistic check to remain in READING mode and avoid state
switches when there is demand to continue reading.
Closes gh-25831
This commit raises the minimum Coroutines version supported
to 1.4.0-M1 and above, and changes usages of awaitFirst() or
awaitFirstOrNull() to awaitSingle() or awaitSingleOrNull()
to fix gh-25007.
