767403 - Fix dependent libs generation on *BSD after bug 763893

Status: RESOLVED FIXED

Description

[Landry Breuil (:gaston)]

dependentlibs.py has the following snippet :

if ext == '.dll':
    func = dependentlibs_dumpbin
elif ext == '.so':
    func = dependentlibs_readelf
elif ext == '.dylib':
    func = dependentlibs_otool

This doesnt take into account all bsd platforms where configure.in sets DLL_SUFFIX to .so.1.0 (or to our controlled-versionning lib variable .so.${SO_VERSION} on OpenBSD), so this breaks with cryptic messages :

Traceback (most recent call last):
  File "/home/buildslave/mozilla-central-i386/build/xpcom/stub/dependentlibs.py", line 102, in <module>
    main()
  File "/home/buildslave/mozilla-central-i386/build/xpcom/stub/dependentlibs.py", line 99, in main
    print '\n'.join(dependentlibs(lib, options.libpaths, func))
UnboundLocalError: local variable 'func' referenced before assignment

I'd suggest matching elf platforms with elif ext[0:3] == '.so':, which i'm testing right now and will post a patch for if it works.

Actually it's a bit more complicated since splitext returns .0 as ext...

also match libname on lib.*.so.*

re.match on lib.*\.so\..* fixes the issue for me and probably netbsd/freebsd

New patch rebased after #767024

Please use fnmatch.fnmatch instead.

use fnmatch to match lib*.so.*

Sure, that also works and is nicer (my python fu is weak)

Please add a whitespace after the comma.

I think you can lift the lib prefix and just use *.so.*

Right, pushed it that way.
