From: Changqing Li <changqing...@windriver.com> When TMPDIR has length 410, bitbake uninative-tarball will fail at do_populate_sdk with error: Failed to open backup database: "TMPDIR/work/x86_64-nativesdk-pokysdk-linux/uninative-tarball/1.0/sdk/image/var/lib/dnf/history.sqlite"
sqlite3 has a hardcode max pathname limit 512, refer [1], and there is a check, refer [2], pathname + 8 > max path name limit(512) is not allowed. So the pathname length need to <= 504. While, length of "TMPDIR/work/x86_64-nativesdk-pokysdk-linux/uninative-tarball/1.0/sdk/image/var/lib/dnf/history.sqlite" is 505, so error happened. We had met similar issue [3], and refer the comments, upstream reject the change of the hardcode length, see [4][5]. This patch try to improve and workaround this issue by lower max TMPDIR length to 400, at least for distro name length <=13, the build can success.
