This patch adds two benchmarks that measure the performance of some
operations of libziparchive.
Both benchmarks are creating a temporary zip file containing file
names of uniformly distributed lengths. The creation of the zip
file is not timed in the benchmarks.
- FindEntry_no_match tries to find an inexisting entry in the files
of the zip archive, in order to force the code to examine all the
files in the archive.
- Iterate_all_files uses the iterate function to list all the files
in the archive.
Bug: N/A
Test: adb shell /data/ziparchive-benchmarks
