Long repro
=========
Build a wrapper to akonadi_html_to_text to know which input makes it fail:
#!/bin/bash
set -euo pipefail
REAL="/usr/bin/akonadi_html_to_text.real"
LOG_DIR="/tmp/akonadi_debug"
mkdir -p "$LOG_DIR"
TS=$(date +%s)
PID=$$
BASE="$LOG_DIR/akonadi_${TS}_${PID}"
STDIN_FILE="${BASE}.stdin"
META_FILE="${BASE}.meta"
# Save stdin first
cat > "$STDIN_FILE"
# Skip empty input entirely
if [ ! -s "$STDIN_FILE" ]; then
rm -f "$STDIN_FILE"
exit 0
fi
# Log metadata
{
echo "timestamp: $(date -Is)"
echo "pid: $$"
echo "args: $*"
echo "stdin_file: $STDIN_FILE"
} > "$META_FILE"
# Execute real binary with captured stdin
"$REAL" "$@" < "$STDIN_FILE"
STATUS=$?
# Log exit status
echo "exit_status: $STATUS" >> "$META_FILE"
# If success, clean up
if [ "$STATUS" -eq 0 ]; then
rm -f "$STDIN_FILE" "$META_FILE"
else
echo "Crash detected. Input preserved at:"
echo " $STDIN_FILE"
echo "Metadata:"
echo " $META_FILE"
fi
exit "$STATUS"
OBSERVED RESULT
Got a SIGABRT with a core dump, attached as a file.
This keep looping creating tons of core dumps until I change the
akonadi_html_to_text binary.
EXPECTED RESULT
akonadi_html_to_text shouldn't crash
