  "message": "midx.MultiPackIndexWriter: a writer for the multipack index format\n\nFromg git documentation[1]: While the pack-indexes provide fast lookup\nper packfile, this performance degrades as the number of packfiles\nincreases, because abbreviations need to inspect every packfile and we\nare more likely to have a miss on our most-recently-used packfile. For\nsome large repositories, repacking into a single packfile is not\nfeasible due to storage space or excessive repack times. (...)\n\nThe multi-pack-index (MIDX for short) stores a list of objects and\ntheir offsets into multiple packfiles. (...) Thus, we can provide\nO(log N) lookup time for any number of packfiles.\n\nThis is a writer of the multipack index format. The test only verifies\nthe \"shape\" of the file, when we get a parser we can check also the\nvalues (specially the large offset handling).\n\nOn the JGit repository, the multipack index generated by this writer\npasses the validation of `git multi-pack-index verify`.\n\n[1] https://git-scm.com/docs/pack-format#_multi_pack_index_midx_files_have_the_following_format\n\nChange-Id: I1fca599c4ebf28154f28f039c2c4cfe75b2dc79d\n",
