This change optimizes the reading of build IDs from ELF files in APKs. Specifically, we stop re-mmapping the entire archive and searching for the ELF file in it by path and just work on the mmap we created initially. Signed-off-by: Daniel Müller <deso@posteo.net>
Now that we have eliminated the re-mapping of APK archives for retrieval of the build ID of the contained ELF file, we no longer need the BuildIdReader::read_build_id_from_apk_elf method. Remove it. Signed-off-by: Daniel Müller <deso@posteo.net>
We want APK ELF addresses to be normalized relative to the ELF file, as that allows for easy symbolization if the ELF file is available. The current code, however, report an address normalized to the containing APK. This change adjusts the logic and documents the property. We also start adding more doc tests.
