Motivation:
JavaDoc of StandardCompressionOptions should point towards public methods. Also, Brotli tests were failing on Windows.
Modification:
Fixed JavaDoc and enabled Brotli tests on Windows.
Result:
Better JavaDoc and Brotli tests will run on Windows
Co-authored-by: Norman Maurer <norman_maurer@apple.com>
Motivation:
Currently, Netty only has BrotliDecoder which can decode Brotli encoded data. However, BrotliEncoder is missing which will encode normal data to Brotli encoded data.
Modification:
Added BrotliEncoder and CompressionOption
Result:
Fixes#6899.
Co-authored-by: Norman Maurer <norman_maurer@apple.com>
Motivation:
The native module is not yet available on aarch64 Mac / Windows thus causing tests in codec/ to fail (specifically all the Brotli ones, since the module could not be loaded).
Modification:
Disable Brotli tests when platform is not supported
Result:
Tests under codec/ now pass under Mac/aarch64 and Windows/aarch64
Motivation:
We failed to account for the last header when estimating the buffer
size. If the data does not compress enough to make space for the
last header we would exceed the ByteBuf's capacity.
Modifications:
Call #ensureWritable with appropriate capacity for footer ByteBuf
befor writing footer.
Result:
If there is not enough space left in the buffer, the buffer will be
expanded.
Motivation:
Various compression codecs are currently hard-coded to only support buffers that are backed by byte-arrays that they are willing to expose.
This is efficient for most of the codecs, but compatibility suffers, as we are not able to freely choose our buffer implementations when compression codecs are involved.
Modification:
Add code to the compression codecs, that allow them to handle buffers that don't have arrays.
For many of the codecs, this unfortunately involves allocating temporary byte-arrays, and copying back-and-forth.
We have to do it that way since some codecs can _only_ work with byte-arrays.
Also add tests to verify that this works.
Result:
It is now possible to use all of our compression codecs with both on-heap and off-heap buffers.
The default buffer choice has not changed, however, so performance should be unaffected.

Motivation:
JUnit 5 is more expressive, extensible, and composable in many ways, and it's better able to run tests in parallel.
Modifications:
Use JUnit5 in tests
Result:
Related to https://github.com/netty/netty/issues/10757
Motivation:
Netty lacks client side support for decompressing Brotli compressed response bodies.
Modification:
* Introduce optional dependency to brotli4j by @hyperxpro. It will be up to the user to provide the brotli4j libraries for the target platform in the classpath. brotli4j is currently available for Linux, OSX and Windows, all for x86 only.
* Introduce BrotliDecoder in codec module
* Plug it onto `HttpContentDecompressor` for HTTP/1 and `DelegatingDecompressorFrameListener` for HTTP/2
* Add test in `HttpContentDecoderTest`
* Add `BrotliDecoderTest` that doesn't extend `AbstractDecoderTest` that looks flaky
Result:
Netty now support decompressing Brotli compressed response bodies.
Motivation:
After the if case, outSize is always 0, so we can simplify the code.
Modification:
Simplify code by not updating and using `isEmpty()`.
Result:
Clearer than before
Motivation:
NullChecks resulting in a NullPointerException or IllegalArgumentException, numeric ranges (>0, >=0) checks, not empty strings/arrays checks must never be anonymous but with the parameter or variable name which is checked. They must be specific and should not be done with an "OR-Logic" (if a == null || b == null) throw new NullPointerEx.
Modifications:
* import static relevant checks
* Replace manual checks with ObjectUtil methods
Result:
All checks needed are done with ObjectUtil, some exception texts are improved.
Fixes#11170
Motivation:
If two different headers end up in the same hash bucket, and you are iterating the header that is not the first in the bucket, and you use the iterator to remove the first element returned from the iterator, then you would get a NullPointerException.
Modification:
Change the DefaultHeaders iterator remove method, to re-iterate the hash bucket and unlink the entry once found, if we don't have any existing iteration starting point.
Also made DefaultHeaders.remove0 package private to avoid a synthetic method indirection.
Result:
Removing from iterators from DefaultHeaders is now robust towards hash collisions.
Motivation:
We had multiple bugs in JdkZlibDecoder which could lead to decoding errors when the data was received in a fragmentated manner.
Modifications:
- Correctly handle skipping of comments
- Correctly handle footer / header decoding
- Add unit test that verifies the correct handling of fragmentation
Result:
Fixes https://github.com/netty/netty/issues/10875
Motivation:
We need to carefully check for null before we pass the cumulation buffer into decodeLast as callDecode(...) may have removed the codec already and so set cumulation to null.
Modifications:
- Check for null and if we see null use Unpooled.EMPTY_BUFFEr
- Only call decodeLast(...) if callDecode(...) didnt remove the handler yet.
Result:
Fixes https://github.com/netty/netty/issues/10802
Motivation:
https in xmlns URIs does not work and will let the maven release plugin fail:

Modifications:
Use http for xmlns
Result:
Be able to use maven release plugin
Motivation:
HTTP is a plaintext protocol which means that someone may be able
to eavesdrop the data. To prevent this, HTTPS should be used whenever
possible. However, maintaining using https:// in all URLs may be
difficult. The nohttp tool can help here. The tool scans all the files
in a repository and reports where http:// is used.
Modifications:
- Added nohttp (via checkstyle) into the build process.
- Suppressed findings for the websites
that don't support HTTPS or that are not reachable
Result:
- Prevent using HTTP in the future.
- Encourage users to use HTTPS when they follow the links they found in
the code.
