+Description: adb: Make compatible with openssl 1.1
+ OpenSSL version 1.1 brought some API changes which broke the build here,
+ fix that by accessing rsa->n (and e) directly, using RSA_get0_key instead.

+Subject: [PATCH] Add environment variable MINETEST_MOD_PATH
+
+This adds an environment variable MINETEST_MOD_PATH.
+When it exists, Minetest will look there for mods
+in addition to ~/.minetest/mods/.  Mods can still be
+installed to ~/.minetest/mods/ with the built-in installer.
+
+With thanks to Leo Prikler.

+ directories.
+
+Before this change, when the source directories hierarchy was
+read-only, the read-only mode would be preserved at the destination,
+preventing child directories to be recreated by a normal user (a
+permission denied error, EACCES would be raised).
+
+* execnet/rsync_remote.py (serve_rsync.receive_directory_structure):
+Bitwise OR to ensure the write bit is set on received directories.
+* testing/test_rsync.py (TestRSync)
+<test_read_only_directories>: New test.
