[jboss-jira] [JBoss JIRA] (AS7-2695) Package APR native libraries correctly

[Mladen Turk (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/AS7-2695?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12651017#comment-12651017 ] 

Mladen Turk commented on AS7-2695:
----------------------------------

Jason,

Not sure what you mean by inconsistent.
Reason why jboss-native is packaged the way it is, so it
can work inside multiple AS versions each having different layout
which constantly changes with each release.

So the solution is to create separate jboss-native-as7 distribution layout
and change LibraryLoader to use the mechanism from NativeLibraryResourceLoader
although NativeLibraryResourceLoader could as well use what we made back in 2008.

BTW, the way the code in NativeLibraryLoader does not support OpenBSD or NetBSD
while supporting some weirdos like MPEI/IX

> The APR libraries for native jbossweb should be packaged in the "lib" directory of the module under the platform specific name, e.g.
> * {{lib/linux-i686/libxxxx.so}}
> * {{lib/linux-x86_64/libxxxx.so}}
> * {{lib/solaris-sparc/libxxxx.so}}
> * {{lib/solaris-sparcv9/libxxxx.so}}
> * {{lib/solaris-i686/libxxxx.so}}
> * {{lib/solaris-x68_64/libxxxx.so}}
> * {{lib/macosx-i686/libxxxx.sl}}
> * {{lib/macosx-x86_64/libxxxx.sl}}
> For the case where you need to vary the library based on the Solaris version, you have two options:
> * (best solution) rework the library to use weak symbols and/or libc probes and/or system call error detection, to detect features which are present and absent and adjust at runtime
> * Introduce more than one library in each of the solaris-xxx directories with the version suffix, e.g. libnative-2.8.so or similar and check for solaris at load time, and if solaris, choose the library with the version encoded in the name
