Description Jenny Severance 2009-11-13 18:22:22 UTC 
Description of problem:
The nsslapd-distribution-plugin should not require the plugin name to begin with "lib". 
Example: "standard_distrib_plugin_Linux.so" will result in failure to load the plugin and the following in the errors log:

13/Nov/2009:09:51:09 -0500] - Netscape Portable Runtime error -5977: /usr//dirsrv/plugins/standard_distrib_plugin_Linux.so: cannot open shared object file: No such file or directory
[13/Nov/2009:09:51:09 -0500] - Could not open library "/usr//dirsrv/plugins/standard_distrib_plugin_Linux.so" for plugin Entry Distribution
[13/Nov/2009:09:51:09 -0500] - ERROR: node cn="o=my_suffix.com",cn=mapping tree,cn=config cannot find distribution plugin. Netscape Portable Runtime -5977 (Failure to load dynamic library.) 


Version-Release number of selected component (if applicable):
DS 9.0

How reproducible:


Steps to Reproduce:
1. place the plugin in /usr/lib<64>/dirsrv/plugins
2. Add the following:

dn: cn=BE_1,cn=ldbm database,cn=plugins,cn=config
objectclass: top
objectclass: extensibleObject
objectclass: nsBackendInstance
cn: BE_1
nsslapd-suffix: o=my_suffix.com

dn: cn=BE_2,cn=ldbm database,cn=plugins,cn=config
objectclass: top
objectclass: extensibleObject
objectclass: nsBackendInstance
cn: BE_2
nsslapd-suffix: o=my_suffix.com

dn: cn=BE_3,cn=ldbm database,cn=plugins,cn=config
objectclass: top
objectclass: extensibleObject
objectclass: nsBackendInstance
cn: BE_3
nsslapd-suffix: o=my_suffix.com

dn: cn="o=my_suffix.com",cn=mapping tree,cn=config
objectclass: top
objectclass: extensibleObject
objectclass: nsMappingTree
cn: "o=my_suffix.com"
nsslapd-state: backend
nsslapd-backend: BE_1
nsslapd-backend: BE_2
nsslapd-backend: BE_3
nsslapd-distribution-plugin: standard_distrib_plugin_Linux.so
nsslapd-distribution-funct: alpha_distribution

3. check the errors log
4. renaming the library to libstandard_distrib_plugin_Linux.so , will resolve the problem.

    Fix Description: We use the function PL_GetLibraryName from NSPR to get the
    platform specific DLL/shared lib filename suffix.  Unfortunately, this funct
    also prepends the string "lib" to the given name if the given file has no
    suffix.  If the given name already has the correct suffix, it does not prepe
    the "lib" to the name.  get_plugin_name() should look for the original
    library name in the string returned by PL_GetLibraryName.  If it is there, a
    has something before it in the string, see if it is "/lib" - if so, remove t
    extraneous "lib" string.  If "/lib" is not there, then just pass the string
    through as is.
    To summarize:
    /full/path/to/name.so -> /full/path/to/name.so - error if /full/path/to/name
    name -> /default/plugin/path/libname.so -> /default/plugin/path/name.so
    name.so -> /default/plugin/path/name.so
