Motivation:
Before this commit, it is impossible to access the path component of the
URI before it has been decoded. This makes it impossible to distinguish
between the following URIs:
/user/title?key=value
/user%2Ftitle?key=value
The user could already access the raw uri value, but they had to calculate
pathEndIdx themselves, even though it might already be cached inside
QueryStringDecoder.
Result:
The user can easily and efficiently access the undecoded path and query.
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.
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:
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:
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:
Currently, QueryStringDecoder#path simply returns the path info as is, without decoding it as the Javadoc states.
Modifications:
* Make QueryStringDecoder#path decode the path info.
* Add tests to QueryStringDecoderTest.
Result:
QueryStringDecoder#path now decodes the path info as expected.
Motivation:
without this check then given a URI with path /path the resulting URL will be /path?null=
Modifications:
check that getRawQuery doesn't return null and only append if not
Result:
urls of the form /path will not have a null?= appended
Motivation:
Sometimes it is useful to be able to access the uri that was used to initialize the QueryStringDecoder.
Modifications:
Add method which allows to retrieve the uri.
Result:
Allow to retrieve the uri that was used to create the QueryStringDecoder.
Motivation:
Persuit for the consistency in method naming
Modifications:
- Remove the 'get' prefix from all HTTP/SPDY message classes
- Fix some inspector warnings
Result:
Consistency
* This is done because we noticed that the previous change limit the usage more then it gave us any benefit. Now it is possible
again to rewrite the url on the fly or reuse the objects when writing a proxy and so limit the GC pressure.
* Fixes also #979
- Rename message types for clarity
- HttpMessage -> FullHttpMessage
- HttpHeader -> HttpMessage
- HttpRequest -> FullHttpRequest
- HttpResponse -> FulllHttpResponse
- HttpRequestHeader -> HttpRequest
- HttpResponseHeader -> HttpResponse
- HttpContent now extends ByteBufHolder; no more content() method
- Make HttpHeaders abstract, make its header access methods public, and
add DefaultHttpHeaders
- Header accessor methods in HttpMessage and LastHttpContent are
replaced with HttpMessage.headers() and
LastHttpContent.trailingHeaders(). Both methods return HttpHeaders.
- Remove setters wherever possible and remove 'get' prefix
- Instead of calling setContent(), a user can either specify the content
when constructing a message or write content into the buffer.
(e.g. m.content().writeBytes(...))
- Overall cleanup & fixes
* Limited maximum number of parameters to 1024 by default and made the
limitation configurable
* QueryStringDecoder is now able to handle an HTTP POST content
Split the project into the following modules:
* common
* buffer
* codec
* codec-http
* transport
* transport-*
* handler
* example
* testsuite (integration tests that involve 2+ modules)
* all (does nothing yet, but will make it generate netty.jar)
This commit also fixes the compilation errors with transport-sctp on
non-Linux systems. It will at least compile without complaints.
