-Subject: [PATCH lttng-tools 2/2] Fix: test: unit: the tree origin can be a
- symlink itself
-
-Problem:
-
-The base tree is defined as "/tmp/.....XXXXXX".
-On systems where "/tmp/" is itself a symlink utils_expand_path will
-expand the tree origin itself.
-
-For example on a base core-image-minimal Yocto build /tmp is a symlink
-to "/var/tmp", which is a symlink to "/var/volatile".
-
-utils_expand_path will return something like this for the symlink test:
-"/var/volative/.....XXXXXX/...." which is the valid result.
-
-Solution:
-
-Simply use realpath on the tree_origin and use this path to perform the
-test validation.
-
-This work was performed in the effort to support yocto fully and be able
-to run the test suite to detect problem as early as possible.
-

-
-The problem was easily reproducible (~6 crash on ~300 runs). A prototype fix
-using mutex around the getgrnam yielded no crash in over 1000 runs. This
-patch yielded the same results as the prototype fix.
-
-Unfortunately we cannot rely on a mutex in liblttng-ctl since we cannot
-enforce the locking for the application using the lib.
-
-Use getgrnam_r instead.
-
-The previous implementation of utils_get_group_id returned the gid of
-the root group (0) on error/not found. lttng_check_tracing_group needs
-to know if an error/not found occured, returning the root group is not
-enough. We now return the gid via the passed parameter. The caller is
-responsible for either defaulting to the root group or propagating the
-error.
-
-We also do not want to warn when used in liblttng-ctl context. We might
-want to move the warning elsewhere in the future. For now, pass a bool
-if we need to warn or not.
