Motivation:
Recently merged ipfilter package has the following problems:
* AbstractIpFilterHandler could be improved to support any SocketAddress types rather than only InetSocketAddress.
* AbstractIpFilterHandler can be removed immediately after decision is made rather than keeping the outcome of the decision as an attribute.
* AbstractIpFilterHandler doesn't have a hook for the accepted addresses.
* The hook method (reject()) needs to be named in line with other handler methods (i.e. channelRejected())
* IpFilterRuleHandler should allow accepting zero rules - it's particularly useful for machine-configured setup (i.e. specifying zero rules disables ipfilter).
* IpFilterRuleType.ALLOW/DENY should be ACCEPT/REJECT for consistency.
Modifications:
* AbstractIpFilterHandler has been renamed to AbstractRemoteAddressFilter and now uses type parameter.
* Added channelAccepted() and renamed reject() to channelRejected()
* Added ChannelHandlerContext as a parameter of accept() so that accept() can add a listener to the closeFuture() of the channel. This way, UniqueIpFilter continue working even if we remove the filtering handler early.
* Various renames
* IpFilterRuleHandler -> RuleBasedIpFilter
* UniqueIpFilterHandler -> UniqueIpFilter
Result:
* Much cleaner API with more extensibility
Motivation:
ChunkedWriteHandler can sometimes fail to write the last chunk of a ChunkedInput due to an I/O error. Subsequently, the ChunkedInput's associated promise is marked as failure and the connection is closed. When the connection is closed, ChunkedWriteHandler attempts to clean up its message queue and to mark their promises as success or failure. However, because the promise of the ChunkedInput, which was consumed completely yet failed to be written, is already marked as failure, the attempt to mark it as success fails, leading a WARN level log.
Modification:
Use trySuccess() instead of setSuccess() so that the attempt to mark a ChunkedInput as success does not raise an exception even if the promise is already done.
Result:
Fixes#2249
- Use ': ' instead of '(...)' for simpler string concatenation and prettier presentation
- Optimize the overall performance of format*() methods
- All format*() methods are now expected to encode the channel information by themselves so that StringBuilder instances are created less often.
- Use a look-up table for generating per-row prefixes
- Hid formatByteBuf(), formatByteBufHolder(), and formatNonByteBuf() from user because a user can always override format(ctx, eventName, arg). For example, to disable hexdump:
protected void format(ChannelHandlerContext ctx, String eventName, Object arg) {
if (arg instanceof ByteBuf) {
super.format(ctx, eventName, arg.toString());
} else {
super.format(ctx, eventName, arg);
}
}
- Fixes#2003 properly
- Instead of using 'bundle' packaging, use 'jar' packaging. This is
more robust because some strict build tools fail to retrieve the
artifacts from a Maven repository unless their packaging is not 'jar'.
- All artifacts now contain META-INF/io.netty.version.properties, which
provides the detailed information about the build and repository.
- Removed OSGi testsuite temporarily because it gives false errors
during split package test and examination.
- Add io.netty.util.Version for easy retrieval of version information
- Fixes#1905
- Call ctx.flush() only when necessary
- Improve the estimation of application and packet buffer sizes
- decode() method now tries to call unwrap() with as many SSL records as
possible to reduce the number of events triggered
