Instead of traversing across leafs() which can lead to an infinite
loop issue with cross-linked libraries, use the dictionary
(libs_dict) created by libraries() to create a set (libs_set) of
every unique library. Every value in libs_dict is also a key in
libs_dict, so every unique library linked to mpv will be a key in
libs_dict. Use set() on libs_dict to return a set of the keys from
libs_dict, and remove binary from the set so that a duplicate of
the binary is not added to the libs directory.
Iterate over libs_set to bundle dylibs while using the libs_dict
to determine which install_names to change.
since the loading order of rpaths is system wide lib path, dev tool path
and then bundle lib path it's possible for the xcode swift libs to be
incompatible with the libs the bundle was build with. this leads to
possible segfaults. if we distribute the bundle we don't want to load
the libs from the dev tools anyway.
in xcode 11 the dynamic swift libraries were moved to a separated
versioned swift folder, which can't be used for linking and only for
distribution. additional to the std dynamic swift lib folder the system
wide folder is needed for linking too.
there were several problems that had to be fixed because of differences
between python2 to python3:
- subprocess.check_output returned an unicode instead of a string
- filter() returns an iterator instead of a list
- recursion limit was reached
first two were fixed by explicitly converting to the needed type or
using the proper function invocation. third was fixed by changing the
recursive process_libraries function to an iterative one.
Fixes#5600, #3316
This fixes usage when the bundle is used on the same machine that Python/Cython
was compiled on. It doesn't fix the harder problem of packaging a full Python
installation in the mpv app bundle (and I'm not sure we actually want that).
Fixes#1549
Move the code that copies the dylib's to the bundle to a new script
(dylib-unhell.py) which is called by osxbundle.py.
dylib-unhell is about 20x faster than the previous implementation. This is
accomplished by removing superflous shell-out operations which are kept track
of using an in memory tree of all the needed dependencies. Moreover the
shell-outs have been further optimized by not requiring a complete shell for
every operation and just using subprocess.call (which is equivalent to Popen).
