An interesting behavior struck me once more after a long long time.
*** 0002:extend_recipe_sysroot(d)
0003:
File: '/layer/layer/poky/meta/classes/staging.bbclass', lineno: 584,
function: extend_recipe_sysroot
0580: if "/bin/" in l or "/sbin/" in l:
0581: # defer /*bin/* files until last in
case they need libs
0582: binfiles[l] = (targetdir, dest)
0583: else:
*** 0584: staging_copyfile(l, targetdir, dest,
postinsts, seendirs)
0585:
0586: # Handle deferred binfiles
0587: for l in binfiles:
0588: (targetdir, dest) = binfiles[l]
File: '/layer/layer/poky/meta/classes/staging.bbclass', lineno: 158,
function: staging_copyfile
0154: os.symlink(linkto, dest)
0155: #bb.warn(c)
0156: else:
0157: try:
*** 0158: os.link(c, dest)
0159: except OSError as err:
0160: if err.errno == errno.EXDEV:
0161: bb.utils.copyfile(c, dest)
0162: else:
Exception: FileExistsError: [Errno 17] File exists:
'/build/tmp/sysroots-components/x86_64/some/path/to/some/deeply/nested/file'
->
'/build/tmp/work/x86_64-linux/some-recipe/1.0-r0/recipe-sysroot-native/some/path/to/some/deeply/nested/file'
This happens in rare case when doing a differential build o a recipe
with hundreds or thousands of native dependencies.
The file mentioned is pretty much random and it's unique (no duplicates
among all the dependencies when it comes to filename+path).
So far I helped myself with ignoring this error by adding
except FileExistsError:
pass
to staging - I wonder if anyone else ever seen this behavior and what's
the best way to deal with it
What comes to my mind is
- ignoring it - but then no one can be sure it's the right file
- falling back to the OSError/EXDEV path and copying over the file requested
- a 3rd option
Any thoughts?
(Just to be sure, this happens like once in a thousand builds and only
on differential builds)
