4Subject: [PATCH lttng-tools 1/2] Fix: test: skip test_getcpu_override on
5 single thread system
6
7There is no value in performing this test on single thread system
8since the only valid value for the cpu field is 0.
9
10This test currently fails on single thread system (i.e yocto runquemu)
11on the test_getcpu_override_fail test case.

4Subject: [PATCH lttng-tools 2/2] Fix: test: unit: the tree origin can be a
5 symlink itself
6
7Problem:
8
9The base tree is defined as "/tmp/.....XXXXXX".
10On systems where "/tmp/" is itself a symlink utils_expand_path will
11expand the tree origin itself.
12
13For example on a base core-image-minimal Yocto build /tmp is a symlink
14to "/var/tmp", which is a symlink to "/var/volatile".
15
16utils_expand_path will return something like this for the symlink test:
17"/var/volative/.....XXXXXX/...." which is the valid result.
18
19Solution:
20
21Simply use realpath on the tree_origin and use this path to perform the
22test validation.
23
24This work was performed in the effort to support yocto fully and be able
25to run the test suite to detect problem as early as possible.

4Subject: [PATCH lttng-tools] Skip when testapp is not present
5
6We expect lttng-ust do be present, this is a wrong assumptions.
7
8This is a quick fix. The real fix is to either detect at runtime
9lttng-ust support or at build time (HAVE_LIBLTTNG_UST_CTL).
10
11This prevent hang for make check done on a build configured with
12--without-lttng-ust.
13
14Upstream-Status: Inappropriate [other]
15Reason: This patch is inappropriate for upstream for 2.10 stable release
16since we do not backport "superficial" fix to the test suite. We do
17backport when a test is broken. The fact that on --without-lttng-ust
18hang is not a "broken" test per-see. Still, a variation of this fix will
19be upstreamed in our master branch and possibly 2.11. The upstreamed
20version will split the test in kernel/ust test and skip them at the
21build system level. This patch is more succinct.

7coredump due to double freeing.

37The problem was easily reproducible (~6 crash on ~300 runs). A prototype fix
38using mutex around the getgrnam yielded no crash in over 1000 runs. This
39patch yielded the same results as the prototype fix.
40
41Unfortunately we cannot rely on a mutex in liblttng-ctl since we cannot
42enforce the locking for the application using the lib.
43
44Use getgrnam_r instead.
45
46The previous implementation of utils_get_group_id returned the gid of
47the root group (0) on error/not found. lttng_check_tracing_group needs
48to know if an error/not found occured, returning the root group is not
49enough. We now return the gid via the passed parameter. The caller is
50responsible for either defaulting to the root group or propagating the
51error.
52
53We also do not want to warn when used in liblttng-ctl context. We might
54want to move the warning elsewhere in the future. For now, pass a bool
55if we need to warn or not.
