+
+  Find roots when constructing process tree, fix #587
+
+which breaks the process tree (‘t’) view in at least some cases.
+I will investigate further...

-This patch deactivates some tests that fail when ldc is built with the command:
-
-./pre-inst-env guix environment guix --pure -- ./pre-inst-env guix build ldc@1.1.0-beta6
-
-When the --keep-failed flag is added to the build command above, and the tests
-run in the resulting /tmp/guix-build-ldc-1.1.0-beta6.drv-* directory, the tests
-pass.

-Subject: [PATCH] 9pfs: use g_malloc0 to allocate space for xattr
-
-9p back-end first queries the size of an extended attribute,
-allocates space for it via g_malloc() and then retrieves its
-value into allocated buffer. Race between querying attribute
-size and retrieving its could lead to memory bytes disclosure.
-Use g_malloc0() to avoid it.

+@item provides many helper methods for specifying rules
+@item offers (lazy) iterator and flattened list interfaces
+@item custom rules implemented with callbacks
+@item breadth-first (default) or pre- or post-order depth-first searching
+@item follows symlinks (by default, but can be disabled)
+@item directories visited only once (no infinite loop; can be disabled)
+@item doesn't chdir during operation
+@item provides an API for extensions
