Motivation:
HttpObjectAggregator differs from HttpServerExpectContinueHandler's handling
of expect headers by not stripping the 'expect' header when a response
is generated.
Modifications:
HttpObjectAggregator now removes the 'expect' header in cases where it generates
a response.
Result:
Consistent and correct behavior between HttpObjectAggregator and HttpServerExpectContinueHandler.
Motivation:
Issue #6695 states that there is an issue when writing empty content via HttpResponseEncoder.
Modifications:
Add two test-cases.
Result:
Verified that all works as expected.
Motivation:
Its wasteful and also confusing that channelReadComplete() is called even if there was no message forwarded to the next handler.
Modifications:
- Only call ctx.fireChannelReadComplete() if at least one message was decoded
- Add unit test
Result:
Less confusing behavior. Fixes [#4312].
Motivation:
08748344d8 introduced two new tests which did not take into account that the multipart delimiter can be between 2 and 16 bytes long.
Modifications:
Take the multipart delimiter length into account.
Result:
Fixes [#7001]
Motivation:
codec-http2 currently does not strictly enforce the HTTP/1.x semantics with respect to the number of headers defined in RFC 7540 Section 8.1 [1]. We currently don't validate the number of headers nor do we validate that the trailing headers should indicate EOS.
[1] https://tools.ietf.org/html/rfc7540#section-8.1
Modifications:
- DefaultHttp2ConnectionDecoder should only allow decoding of a single headers and a single trailers
- DefaultHttp2ConnectionEncoder should only allow encoding of a single headers and optionally a single trailers
Result:
Constraints of RFC 7540 restricting the number of headers/trailers is enforced.
Motivation:
HttpPostRequestEncoder maintains an internal buffer that holds the
current encoded data. There are use cases when this internal buffer
becomes null, the next chunk processing implementation should take
this into consideration.
Modifications:
- When preparing the last chunk if currentBuffer is null, mark
isLastChunkSent as true and send LastHttpContent.EMPTY_LAST_CONTENT
- When calculating the remaining size take into consideration that the
currentBuffer might be null
- Tests are based on those provided in the issue by @nebhale and @bfiorini
Result:
Fixes#5478
Motivation:
- A `HttpPostMultipartRequestDecoder` contains two pairs of the same methods: `readFileUploadByteMultipartStandard`+`readFileUploadByteMultipart` and `loadFieldMultipartStandard`+`loadFieldMultipart`.
- These methods use `NotEnoughDataDecoderException` to detecting not last data chunk (exception handling is very expensive).
- These methods can be greatly simplified.
- Methods `loadFieldMultipart` and `loadFieldMultipartStandard` has an unnecessary catching for the `IndexOutOfBoundsException`.
Modifications:
- Remove duplicate methods.
- Replace handling `NotEnoughDataDecoderException` by the return of a boolean result.
- Simplify code.
Result:
The code is cleaner and easier to support. Less exception handling logic.
Motivation:
1. Some encoders used a `ByteBuf#writeBytes` to write short constant byte array (2-3 bytes). This can be replaced with more faster `ByteBuf#writeShort` or `ByteBuf#writeMedium` which do not access the memory.
2. Two chained calls of the `ByteBuf#setByte` with constants can be replaced with one `ByteBuf#setShort` to reduce index checks.
3. The signature of method `HttpHeadersEncoder#encoderHeader` has an unnecessary `throws`.
Modifications:
1. Use `ByteBuf#writeShort` or `ByteBuf#writeMedium` instead of `ByteBuf#writeBytes` for the constants.
2. Use `ByteBuf#setShort` instead of chained call of the `ByteBuf#setByte` with constants.
3. Remove an unnecessary `throws` from `HttpHeadersEncoder#encoderHeader`.
Result:
A bit faster writes constants into buffers.
Motivation:
Right now HttpRequestEncoder does insertion of slash for url like http://localhost?pararm=1 before the question mark. It is done not effectively.
Modification:
Code:
new StringBuilder(len + 1)
.append(uri, 0, index)
.append(SLASH)
.append(uri, index, len)
.toString();
Replaced with:
new StringBuilder(uri)
.insert(index, SLASH)
.toString();
Result:
Faster HttpRequestEncoder. Additional small test. Attached benchmark in PR.
Benchmark Mode Cnt Score Error Units

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.
Result:
Reduce overhead from string-to-bytes conversion.
Motivation:
These headers can be used to prevent clickjacking.
Modifications:
Add static fields for content-security-policy and x-frame-options
Result:
Expose general useful names
Motivation:
A life cycle of QueryStringEncoder is simple: create, append params, convert to String. Current realization collect params in the list, and calculate an URI string in `toString` method. We can simplify this: don't store params to the list, and immediately append parameters to the `StringBuilder`.
Modifications:
- Remove list for params and remove a tuple class `Param`.
- Use one common `StringBuilder` and append parameters into it.
- Resolve `TODO` in the `encodeParam` method.
Result:
Less allocations (no `ArrayList`, no `Param` tuples). Second `toString` call is faster.
Motivation:
PR #6811 introduced a public utility methods to decode hex dump and its parts, but they are not visible from netty-common.
Modifications:
1. Move the `decodeHexByte`, `decodeHexDump` and `decodeHexNibble` methods into `StringUtils`.
2. Apply these methods where applicable.
3. Remove similar methods from other locations (e.g. `HpackHex` test class).
Result:
Less code duplication.
Motivation:
If the content-length does not parse as a number, leniency causes this
to instead be parsed as the default value. This leads to bodies being
silently ignored on requests which can be incredibly dangerous. Instead,
if the content-length header is invalid, an exception should be thrown
for upstream handling.
Modifications:
This commit removes the leniency in parsing the content-length header by
allowing a number format exception, if thrown, to escape from the method
rather than falling back to the default value.
Result:
In invalid content-length header will not be silently ignored.
Motivation:
For multi-line headers HttpObjectDecoder uses StringBuilder.append(a).append(b) pattern that could be easily replaced with regular a + b. Also oparations with a and b moved out from concat operation to make it friendly for StringOptimizeConcat optimization and thus - faster.
Modification:
StringBuilder.append(a).append(b) reaplced with a + b. Operations with a and b moved out from concat oparation.
Result:
Code simpler to read and faster.
Motivation:
The class `HttpPostRequestEncoder` has minor issues:
- The `encodeNextChunkMultipart()` method contains two identical blocks of code with a difference only in the cast interfaces: `Attribute` vs `HttpData`. Because the `Attribute` is extended by `HttpData`, the block with the `Attribute` can be safely deleted.
- The `getNewMultipartDelimiter()` method contains a redundant `toLowerCase()`.
- The `addBodyFileUploads()` method throws `NPE` instead of `IllegalArgumentException`.
Modifications:
- Remove duplicated code block from `encodeNextChunkMultipart()`.
- Remove redundant `toLowerCase()` from `getNewMultipartDelimiter()`.
- Replace `NPE` with `IllegalArgumentException` in `addBodyFileUploads()`.
- Use `ObjectUtil#checkNotNull` where possible.
Result:
More correct and clean code.
Motivations:
1. There are duplicated implementations of decoding hex strings. #6797
2. ByteBufUtil.HexUtil.decodeHexDump does not handle substring start
index properly and does not decode hex byte rigorously.
Modifications:
1. Function decodeHexByte is moved from QueryStringDecoder into ByteBufUtil.
2. ByteBufUtil.HexUtil.decodeHexDump is changed to use decodeHexByte.
3. Tests are Updated accordingly.
Result:
Fixed#6797 and made hex decoding functions more robust.
Motivation:
A `SeekAheadNoBackArrayException` used as check for `ByteBuf#hasArray`. The catch of exceptions carries a large overhead on stack trace filling, and this should be avoided.
Modifications:
- Remove the class `SeekAheadNoBackArrayException` and replace its usage with `if` statements.
- Use methods from `ObjectUtils` for better readability.
- Make private methods static where it make sense.
- Remove unused private methods.
Result:
Less of exception handling logic, better performance.
Motivation:
If a full HttpResponse with a Content-Length header is encoded by the HttpContentEncoder subtypes the Content-Length header is removed and the message is set to Transfer-Encoder: chunked. This is an unnecessary loss of information about the message content.
Modifications:
- If a full HttpResponse has a Content-Length header, the header is adjusted after encoding.
Result:
Complete messages continue to have the Content-Length header after encoding.
Motivation:
QueryStringDecoder has several problems:
- doesn't decode correctly path part with `+` (plus) sign in it,
- doesn't cut a `fragment` (after `#`) from query string (see RFC 3986),
- doesn't work correctly with encoding,
- treat `%%` as a percent character escaping (it's don't described in RFC).
Modifications:
- leave `+` chars in a `path` part of uri string,
- ignore `fragment` part (after `#`),
- correctly work with encoding.
- don't treat `%%` as escaping for the `%`.
Result:
Fixed issues from #6745.
Motivation:
Allow subclasses of HttpObjectEncoder other than HttpServerCodec to override the isContentAlwaysEmpty method
Modification:
Change the method visibility from package private to protected
Result:
Fixes#6761
Motivation:
Fix the regression recently introduced that causes already encoded responses to be encoded again as gzip
Modification:
instead of just looking for IDENTITY, anything set for Content-Encoding should be respected and left as-is
added unit tests to capture this use case
Result:
Fixes#6784
Motivation
RFC 1945 (see section 3.1) says that request lines may not have a version in which case the request is assumed to be HTTP/0.9. We don't necessarily want to support that but the existing Exception should indicate the possibility of the request being HTTP/0.9 and give the user a chance to track it down.
Modifications
Indicate in the Exception's message that the request is possibly HTTP/0.9.
Result
Fixes#6739
Motivation:
The status 308 is defined by RFC7538.
This RFC has currently the state Proposed Standard since 2 years, but the status code is already handle by all browsers (Chrome, Firefox, Edge, Safari, …).
To let developer handles easily this status code, it is added into this list.
Modifications:
Added this status code in the list of all status codes and changed the valudOf() method
Result:
Status code 308 included
__Motivation__
`HttpClientCodec` skips HTTP decoding on the connection after a successful HTTP CONNECT response is received.
This behavior follows the spec for a client but pragmatically, if one creates a client to use a proxy transparently, the codec becomes useless after HTTP CONNECT.
Ideally, one should be able to configure whether HTTP CONNECT should result in pass-through or not. This will enable client writers to continue using HTTP decoding even after HTTP CONNECT.
__Modification__
Added overloaded constructors to accept `parseHttpPostConnect`. If this parameter is `true` then the codec continues decoding even after a successful HTTP CONNECT.
Also fixed a bug in the codec that was incrementing request count post HTTP CONNECT but not decrementing it on response. Now, the request count is only incremented if the codec is not `done`.
__Result__
Easier usage by HTTP client writers who wants to connect to a proxy but still decode HTTP for their users for subsequent requests.
Motivation:
Some JUnit assert calls can be replaced by simpler.
Modifications:
Replacement with a more suitable methods.
Result:
More informative JUnit reports.
Motivation:
HttpServerKeepAliveHandler throws unexpected error when I do ctx.writeAndFlush(msg, ctx.voidPromise()); where msg is with header "Connection:close".
Modification:
HttpServerKeepAliveHandler does promise.unvoid() before adding close listener.
Result:
No error for VoidChannelPromise with HttpServerKeepAliveHandler. Fixes [#6698].
Motivation:
It would be more flexible to make getCharset and getMimeType code usable not only for HttpMessage entity but just for any CharSequence. This will improve usability in general purpose code and will help to avoid multiple fetching of ContentType header from a message. It could be done in an external code once and CharSequence method versions could be applied.
Modification:
Expose HttpUtil#getMimeType, HttpUtil#getCharsetAsString, HttpUtil#getCharset versions which works with CharSequence. New methods are reused in the old ones which work with HttpMessage entity.
Result:
More flexible methods set with a good code reusing.
Motivation:
WebSocket decoding throws exceptions on failure that should cause the
pipline to close. These are currently ignored in the
`WebSocketProtocolHandler` and `WebSocketServerProtocolHandler`. In
particular, this means that messages exceding the max message size will
cause the channel to close with no reported failure.
Modifications:
Re-fire the event just before closing the socket to allow it to be
handled appropriately.
Result:
Closes [#3063].
Motivation:
If Content-Encoding: IDENTITY is used we should not try to compress the http message but just let it pass-through.
Modifications:
Remove "!"
Result:
Fixes [#6689]
It is generally useful to have origin http servers respond to
"expect: continue-100" as soon as possible but applications without a
HttpObjectAggregator in their pipelines must use boiler plate to do so.
Modifications:
Introduce the HttpServerExpectContinueHandler handler to make it easier.
Result:
Less boiler plate for http application authors.
Motivation:
DiskFileUpload creates temporary files for storing user uploads containing the user provided file name as part of the temporary file name. While most security problems are prevented by using "new File(userFileName).getName()" a small risk for bugs or security issues remains.
Modifications:
Use a constant string as file name and rely on the callers use of File.createTemp to ensure unique disk file names.
Result:
A slight security improvement at the cost of a little more obfuscated temp file names.
Motivation:
We miss to retain a slice before return it to the user and so an reference count error may accour later on.
Modifications:
Use readRetainedSlice(...) and so ensure we retain the buffer before hand it of to the user.
Result:
Fixes [#6626].
Motivation:
Commit #d675febf07d14d4dff82471829f974369705655a introduced a regression in QueryStringEncoder, resulting in whitespace being converted into a literal `+` sign instead of `%20`.
Modification:
Modify `encodeComponent` to pattern match and replace on the result of the call to `URLEncoder#encode`
Result:
Fixes regression
Motivation:
https://tools.ietf.org/html/rfc7230#section-3.3.2 states that a 204 response MUST NOT include a Content-Length header. If the HTTP version permits keep alive these responses should be treated as keeping the connection alive even if there is no Content-Length header.
Modifications:
- HttpServerKeepAliveHandler#isSelfDefinedMessageLength should account for 204 respones
Result:
Fixes https://github.com/netty/netty/issues/6549.
Motivation:
Currently netty is receiving HTTP request by ByteBuf and store it as "CharSequence" on HttpObjectDecoder. During this operation, all character on ByteBuf is moving to char[] without breaking encoding.
But in process() function, type casting from byte to char does not consider msb (sign-bit). So the value over 127 can be casted wrong value. (ex : 0xec in byte -> 0xffec in char). This is type casting bug.
Modification:
Fix type casting
Result:
Non-latin characters work.
Motivation:
The updated HTTP/1.x RFC allows for header values to be CSV and separated by OWS [1]. CombinedHttpHeaders should remove this OWS on insertion.
[1] https://tools.ietf.org/html/rfc7230#section-7
Modification:
CombinedHttpHeaders doesn't account for the OWS and returns it back to the user as part of the value.
Result:
Fixes#6452
Motivation:
We used some deprecated Mockito methods.
Modifications:
- Replace deprecated method usage
- Some cleanup
Result:
No more usage of deprecated Mockito methods. Fixes [#6482].
Motivation:
Some classes have fields which can be local.
Modifications:
Convert fields to the local variable when possible.
Result:
Clean up. More chances for young generation or scalar replacement.
Motivation:
We only need to add the port to the HOST header value if its not a standard port.
Modifications:
- Only add port if needed.
- Fix parsing of ipv6 address which is enclosed by [].
Result:
Fixes [#6426].
Motivation:
Make code easier to read, make WebSocketServerProtocolHandshakeHandler.getWebSocketLocation method faster.
Modification:
WebSocket path check moved to separate method. Get header operation moved out from concat operation.
Result:
WebSocketServerProtocolHandshakeHandler.getWebSocketLocation is faster as OptimizeStringConcat could be applied. Code easier to read.
Motivation:
QueryStringDecoder and QueryStringEncoder contained some code that could either cleaned-up or optimized.
Modifications:
- Fix typos in exception messages and javadocs
- Precompile Pattern
- Make use of StringUtil.EMPTY_STRING
Result:
Faster and cleaner code.
Motivation:
Calling a static method is faster then dynamic
Modifications:
Add 'static' keyword for methods where it missed
Result:
A bit faster method calls
Motivation:
We have our own ThreadLocalRandom implementation to support older JDKs . That said we should prefer the JDK provided when running on JDK >= 7
Modification:
Using ThreadLocalRandom implementation of the JDK when possible.
Result:
Make use of JDK implementations when possible.
Motivation:
The allowMaskMismatch parameter used throughout websocketx allows frames
with noncompliant masks when set to true, not false.
Modification:
Changed the javadoc comment everywhere it appears.
Result:
Fixes#6387
Motivation:
Today, the HTTP codec in Netty responds to HTTP/1.1 requests containing
an "expect: 100-continue" header and a content-length that exceeds the
max content length for the server with a 417 status (Expectation
Failed). This is a violation of the HTTP specification. The purpose of
this commit is to address this situation by modifying the HTTP codec to
respond in this situation with a 413 status (Request Entity Too
Large). Additionally, the HTTP codec ignores expectations in the expect
header that are currently unsupported. This commit also addresses this
situation by responding with a 417 status.
Handling the expect header is tricky business as the specification (RFC
2616) is more complicated than it needs to be. The specification defines
the legitimate values for this header as "100-continue" and defines the
notion of expectatation extensions. Further, the specification defines a
417 status (Expectation Failed) and this is where implementations go
astray. The intent of the specification was for servers to respond with
417 status when they do not support the expectation in the expect
header.
The key sentence from the specification follows:
The server MUST respond with a 417 (Expectation Failed) status if
any of the expectations cannot be met or, if there are other
problems with the request, some other 4xx status.
That is, a server should respond with a 417 status if and only if there
is an expectation that the server does not support (whether it be
100-continue, or another expectation extension), and should respond with
another 4xx status code if the expectation is supported but there is
something else wrong with the request.
Modifications:
This commit modifies the HTTP codec by changing the handling for the
expect header in the HTTP object aggregator. In particular, the codec
will now respond with 417 status if any expectation other than
100-continue is present in the expect header, the codec will respond
with 413 status if the 100-continue expectation is present in the expect
header and the content-length is larger than the max content length for
the aggregator, and otherwise the codec will respond with 100 status.
Result:
The HTTP codec can now be used to correctly reply to clients that send a
100-continue expectation with a content-length that is too large for the
server with a 413 status, and servers that use the HTTP codec will now
no longer ignore expectations that are not supported (any value other
than 100-continue).
Motivation:
Netty 4.1 introduced AsciiString and defines HttpHeaderNames constants
as such.
It would be convenient to be able to pass them to `exposeHeaders` and
`allowedRequestHeaders` directly without having to call `toString`.
Modifications:
Add `exposeHeaders` and `allowedRequestHeaders` overloads that take a
`CharSequence`.
Result:
More convenient API
Motivation:
DefaultCookie currently used an undocumented magic value for undefined
maxAge.
Clients need to be able to identify such value so they can implement a
proper CookieJar.
Ideally, we should add a `Cookie::isMaxAgeDefined` method but I guess
we can’t add a new method without breaking API :(
Modifications:
Add a new constant on `Cookie` interface so clients can use it to
compare with value return by `Cookie.maxAge` and decide if `maxAge` was
actually defined.
Result:
Clients have a better documented way to check if the maxAge attribute
was defined.
Motivation:
We used various mocking frameworks. We should only use one...
Modifications:
Make usage of mocking framework consistent by only using Mockito.
Result:
Less dependencies and more consistent mocking usage.
Motivation:
HttpObjectAggregator yields full HTTP messgaes (AggregatedFullHttpMessages) that don't respect decoder result when copied/replaced.
Modifications:
Copy the decoding result over to a new instance produced by AggregatedFullHttpRequest.replace or AggregatedFullHttpResponse.replace .
Result:
DecoderResult is now copied over when an original AggregatedFullHttpMessage is being replaced (i.e., AggregatedFullHttpRequest.replace or AggregatedFullHttpResponse.replace is being called).
New unit tests are passing on this branch but are failing on master.
Motivation:
HttpUtil.setTransferEncodingChunked could add a second Transfer-Encoding
header if one was already present. While this is technically valid, it
does not appear to be the intent of the method.
Result:
Only one Transfer-Encoding header is present after calling this method.
Motivation:
In Netty, currently, the HttpPostRequestEncoder only supports POST, PUT, PATCH and OPTIONS, while the RFC 7231 allows with a warning that GET, HEAD, DELETE and CONNECT use a body too (but not TRACE where it is explicitely not allowed).
The RFC in chapter 4.3 says:
"A payload within a XXX request message has no defined semantics;
sending a payload body on a XXX request might cause some existing
implementations to reject the request."
where XXX can be replaced by one of GET, HEAD, DELETE or CONNECT.
Current usages, on particular in REST mode, tend to use those extra HttpMethods for such queries.
So this PR proposes to remove the current restrictions, leaving only TRACE as explicitely not supported.
Modification:
In the constructor, where the test is done, replacing all by checking only against TRACE, and adding one test to check that all methods are supported or not.
Result:
Fixes#6138.
Motivation:
cb139043f3 introduced special handling of response to HEAD requests. Due a bug we failed to handle FullHttpResponse correctly.
Modifications:
Correctly handle FullHttpResponse for HEAD requests.
Result:
Works as expected.
Motivation:
We should have a unit test which explicitly tests a HTTP message being split between multiple ByteBuf objects.
Modifications:
- Add a unit test to HttpRequestDecoderTest which splits a request between 2 ByteBuf objects
Result:
More unit test coverage for HttpObjectDecoder.
Motivation:
Enables optional .startsWith() matching of req.uri() with websocketPath.
Modifications:
New checkStartsWith boolean option with default false value added to both WebSocketServerProtocolHandler and WebSocketServerProtocolHandshakeHandler. req.uri() matching is based on this option.
Result:
By default old behavior matching via .equal() is preserved. To use checkStartsWith use constructor shortcut: new WebSocketServerProtocolHandler(websocketPath, true) or fill this flag on full form of constructor among other options.
request with a 'content-encoding: chunked' header
Motivation:
It is valid to send a response to a HEAD request that contains a transfer-encoding: chunked header, but it is not valid to include a body, and there is no way to do this using the netty4 HttpServerCodec.
The root cause is that the netty4 HttpObjectEncoder will transition to the state ST_CONTENT_CHUNK and the only way to transition back to ST_INIT is through the encodeChunkedContent method which will write the terminating length (0\r\n\r\n\r\n), a protocol error when responding to a HEAD request
Modifications:
- Keep track of the method of the request and depending on it handle the response differently when encoding it.
- Added a unit test.
Result:
Correclty handle HEAD responses that are chunked.
Motivation:
According to https://www.ietf.org/rfc/rfc2388.txt 4.4, filename after "content-disposition" is optional and arbitrary (does not need to match a real filename).
Modifications:
This change supports an extra addBodyFileUpload overload to precise the filename (default to File.getName). If empty or null this argument should be ignored during encoding.
Result:
- A backward-compatible addBodyFileUpload(String, File, String, boolean) to use file.getName() as filename.
- A new addBodyFileUpload(String, String, File, String, boolean) overload to precise filename
- Couple of tests for the empty use case
Motivation:
IntelliJ issues several warnings.
Modifications:
* `ClientCookieDecoder` and `ServerCookieDecoder`:
* `nameEnd`, `valueBegin` and `valueEnd` don't need to be initialized
* `keyValLoop` loop doesn't been to be labelled, as it's the most inner one (same thing for labelled breaks)
* Remove `if (i != headerLen)` as condition is always true
* `ClientCookieEncoder` javadoc still mention old logic
* `DefaultCookie`, `ServerCookieEncoder` and `DefaultHttpHeaders` use ternary ops that can be turned into simple boolean ones
* `DefaultHeaders` uses a for(int) loop over an array. It can be turned into a foreach one as javac doesn't allocate an iterator to iterate over arrays
* `DefaultHttp2Headers` and `AbstractByteBuf` `equal` can be turned into a single boolean statement
Result:
Cleaner code
Motivation:
* DefaultHeaders from netty-codec has some duplicated logic for header date parsing
* Several classes keep on using deprecated HttpHeaderDateFormat
Modifications:
* Move HttpHeaderDateFormatter to netty-codec and rename it into HeaderDateFormatter
* Make DefaultHeaders use HeaderDateFormatter
* Replace HttpHeaderDateFormat usage with HeaderDateFormatter
Result:
Faster and more consistent code
Motivation:
code assumes a numeric value of 0 means no digits were read between separators, which fails for timestamps like 00:00:00.
also code accepts invalid timestamps like 0:0:000
Modifications:
explicitly check for number of digits between separators instead of relying on the numeric value.
also add tests.
Result:
timestamps with 00 successfully parse, timestamps with 000 no longer
Signed-off-by: radai-rosenblatt <radai.rosenblatt@gmail.com>
Motivation:
The method HttpUtil.getCharsetAsString(...) is missleading as its return type is CharSequence and not String.
Modifications:
Deprecate HttpUtil.getCharsetAsString(...) and introduce HttpUtil.getCharsetAsSe
quence(...).
Result:
Less confusing method name.
Motivation:
* RFC6265 defines its own parser which is different from RFC1123 (it accepts RFC1123 format but also other ones). Basically, it's very lax on delimiters, ignores day of week and timezone. Currently, ClientCookieDecoder uses HttpHeaderDateFormat underneath, and can't parse valid cookies such as Github ones whose expires attribute looks like "Sun, 27 Nov 2016 19:37:15 -0000"
* ServerSideCookieEncoder currently uses HttpHeaderDateFormat underneath for formatting expires field, and it's slow.
Modifications:
* Introduce HttpHeaderDateFormatter that correctly implement RFC6265
* Use HttpHeaderDateFormatter in ClientCookieDecoder and ServerCookieEncoder
* Deprecate HttpHeaderDateFormat
Result:
* Proper RFC6265 dates support
* Faster ServerCookieEncoder and ClientCookieDecoder
* Faster tool for handling headers such as "Expires" and "Date"
Motiviation:
We used ReferenceCountUtil.releaseLater(...) in our tests which simplifies a bit the releasing of ReferenceCounted objects. The problem with this is that while it simplifies stuff it increase memory usage a lot as memory may not be freed up in a timely manner.
Modifications:
- Deprecate releaseLater(...)
- Remove usage of releaseLater(...) in tests.
Result:
Less memory needed to build netty while running the tests.
Motivation:
If the wsURL contains an encoded query, it will be decoded when generating the raw path. For example if the wsURL is http://test.org/path?a=1%3A5, the returned raw path would be /path?a=1:5
Modifications:
Use wsURL.getRawQuery() rather than wsURL.getQuery()
Result:
rawPath will now return /path?a=1%3A5
Motivation:
Some commons values are missing from HttpHeader values constants.
Modifications:
- Add constants for "application/json" Content-Type
- Add constants for "gzip,deflate" Content-Encoding
Result:
More HttpHeader values constants available, both in
`HttpHeaders.Values` and `HttpHeaderValues`.
Motivation:
The HttpObjectAggregator never appends a 'Connection: close' header to
the response of oversized messages even though in the majority of cases
its going to close the connection.
Modification:
This PR addresses that by ensuring the requisite header is present when
the connection is going to be closed.
Result:
Gracefully signal that we are about to close the connection.
Motivation:
We need to ensure we not add the Transfer-Encoding header if the HttpMessage is EOF terminated.
Modifications:
Only add the Transfer-Encoding header if an Content-Length header is present.
Result:
Correctly handle HttpMessage that is EOF terminated.
Motivation:
We want to reject the upgrade as quickly as possible, so that we can
support streamed responses.
Modifications:
Reject the upgrade as soon as we inspect the headers if they're wrong,
instead of waiting for the entire response body.
Result:
If a remote server doesn't know how to use the http upgrade and tries to
responsd with a streaming response that never ends, the client doesn't
buffer forever, but can instead pass it along. Fixes#5954
Motivation:
the build doesnt seem to enforce this, so they piled up
Modifications:
removed unused import lines
Result:
less unused imports
Signed-off-by: radai-rosenblatt <radai.rosenblatt@gmail.com>
Motivation:
The Javadocs of HttpUtil.getContentLength(HttpMessage, long) and its int overload state that the provided default value is returned if the Content-Length value is not a number. NumberFormatException is thrown instead.
Modifications:
Correctly handle when the value is not a number.
Result:
API works as stated in javadocs.
