Related: #2952
Motivation:
META-INF/io.netty.versions.properties in netty-all-*.jar does not
contain the version information about the netty-transport-epoll module.
Modifications:
Fix a bug in the regular expression in pom.xml, so that the artifacts
with a classifier is also included in the version properties file.
Result:
The version information of all modules are included in the version
properties file, and Version.identify() does not miss
netty-transport-epoll.
Motivation:
maven-antrun-plugin does not redirect stdin, and thus it's impossible to
run interactive examples such as securechat-client and telnet-client.
org.codehaus.mojo:exec-maven-plugin redirects stdin, but it buffers
stdout and stderr, and thus an application output is not flushed timely.
Modifications:
Deploy a forked version of exec-maven-plugin which flushes output
buffers in a timely manner.
Result:
Interactive examples work. Launches faster than maven-antrun-plugin.
Motivation:
- dependencyVersionsDir property is not resolved during the build
process. The build doesn't fail because of this, but it creates an
ugly directory.
- All-in-one JAR contains libnetty-tcnative.so, which is not part of the
all-in-one JAR.
Modifications:
- Fix an incorrect property name
(dependencyVersionDir -> dependencyVersionsDir)
- Exclude libnetty-tcnative.so
- Remove unnecessary includes in source expanding configuration
Result:
- Cleaner pom.xml
- We do not ship libnetty-tcnative.so in all-in-one JAR anymore, which
is correct, because strictly speaking the native library belongs to
org.apache.tomcat.jni package.
Motivation:
exec-maven-plugin does not flush stdout and stderr, making the console
output from the examples invisible to users
Modification:
Use maven-antrun-plugin instead
Result:
A user sees the output from the examples immediately.
Motivation:
oss.sonatype.org refuses to promote an artifact if it doesn't have the
default JAR (the JAR without classifier.)
Modifications:
- Generate both the default JAR and the native JAR to make
oss.sonatype.org happy
- Rename the profile 'release' to 'restricted-release' which reflects
what it really does better
- Remove the redundant <quickbuild>true</quickbuild> in all/pom.xml
We specify the profile 'full' that triggers that property already
in maven-release-plugin configuration.
Result:
oss.sonatype.org is happy. Simpler pom.xml
Motivation:
Netty must be released from RHEL 6.5 x86_64 or compatible so that:
1) we ship x86_64 version of epoll transport officially, and
2) we ensure the ABI compatibility with older GLIBC versions.
The shared library built on a distribution with newer GLIBC will not
run on older distributions.
Modifications:
- When 'release' profile is active, perform an additional check using
maven-enforcer-plugin so that 'mvn release:*' fails when running on
non-RHEL6.5. This rule is active only when releasing, so a user
should not be affected.
- Simplify maven-release-plugin configuration by removing redundant
profiles such as 'linux'. 'linux' is automatically activated when
releasing because we now enforce the release occurs on linux-x86_64.
- Remove the no-osgi profile, which is unused
- Remove the reference to 'sonatype-oss-release' profile in all/pom.xml,
because we always specify 'release' profile when releasing
- Rename the profile 'linux-native' to 'linux' for brevity
- Upgrade oss-parent and maven-enforcer-plugin
Result:
No one can make a mistake to release Netty on an environment that can
produce incompatible or missing native library.
