Log from valgrind while reproducing the bug under RHEL 7.6
TEST SETUP 1
Distro: RHEL 7.6
Component version: tracker-1.10.5-6.el7
TEST PROCEDURE 1
1. Create a file with invalid UTF-8 name:
# touch ~/aaa$'\363'
2. Stop the indexing from tracker:
# tracker daemon --terminate
3. Install a tool for checking memory leaks and corruption:
# yum install -y valgrind
4. Start valgrind:
# valgrind /usr/libexec/tracker-miner-fs
5. Open another terminal.
6. Trigger the memory corruption:
# touch ~/bbb$'\363'
TEST SETUP 2 Distro: RHEL-7.8-20190912.3 Component version: tracker-1.10.5-8.el7 TEST PROCEDURE 2 Repeat TEST PROCEDURE 1 (comment #5). RESULT 2 The bug does NOT appear. OUTCOME
Upgrading component: tracker
from: 1.10.5-6.el7
to: 1.10.5-8.el7
has fixed the bug.
