This is not ideal for our purpose if we want22to check for consistency of the tensor data even if the metadata content of the23gguf KV store has been updated.24 25This program is designed to hash a gguf tensor payload on a 'per tensor layer'26in addition to a 'entire tensor model' hash. The intent is that the entire27tensor layer can be checked first but if there is any detected inconsistencies,28then the per tensor hash can be used to narrow down the specific tensor layer29that has inconsistencies.30 31For Maintainers:32- Detection of tensor inconsistency during development and automated tests33 - This is served by xxh64 which is fast34 - This is also served by having per tensor layer to assist in narrowing down35 the location of the faulty tensor layer36 - This is also served by sha1 which is much slower but more widely supported37 38For Model Creators:39- Optional consistent UUID generation based on model tensor content40 - This is served by UUIDv5 which is useful for databases keys41 - llama.cpp UUIDv5 Namespace: `ef001206-dadc-5f6d-a15f-3359e577d4e5`42 - Made via UUIDv5 URL namespace of `en.wikipedia.org/wiki/Llama.cpp`43 44For Model Users:45- Assurance of tensor layer integrity even if metadata was updated46 - This is served by sha256 which is still considered very secure as of 202447 48### Design Note49 50- The default behavior of this program if no arguments is provided is to hash51 using xxhash's xxh32 mode because it is very fast and is primarily targeted52 towards maintainers who may want to use this in automated tests.53- xxhash support xxh32 and xxh128 for 32bit hash and 128bit hash respectively54 however we picked 64bit xxhash as most computers are 64bit as of 2024 and thus55 would have a better affinity to calculating hash that is 64bit in size.56 57## Compile Example58 59```bash60cmake -B build -DCMAKE_BUILD_TYPE=Debug -DLLAMA_FATAL_WARNINGS=ON61make -C build clean62make -C build llama-gguf-hash VERBOSE=163./build/bin/llama-gguf-hash test.gguf64./build/bin/llama-gguf-hash --xxh64 test.gguf65./build/bin/llama-gguf-hash --sha1 test.gguf66./build/bin/llama-gguf-hash --uuid test.gguf67./build/bin/llama-gguf-hash --sha256 test.gguf68```69 70## Generation and Verification Example71 72To generate we may use this command73 74```bash75./llama-gguf-hash --all test.gguf > test.gguf.manifest76```77 78Which would generate a manifest that looks like below, which contains multiple hash type and per tensor layer hashes as well79(This excludes UUID as that is an ID not a hash)80 81```bash82xxh64 f66e9cd66a4396a0 test.gguf:tensor_083sha1 59f79ecefd8125a996fdf419239051a7e99e5f20 test.gguf:tensor_084sha256 c0510d38fa060c46265e0160a85c7243096b01dd31c2f355bdbb5516b20de1bd test.gguf:tensor_085xxh64 7d3a1f9ac04d0537 test.gguf:tensor_186sha1 4765f592eacf096df4628ba59476af94d767080a test.gguf:tensor_187sha256 8514cbcc73692a2c56bd7a33a022edd5ff819614bd23b19915d7224387f397a7 test.gguf:tensor_188xxh64 a0af5d700049693b test.gguf:tensor_289sha1 25cbfbad4513cc348e2c95ebdee69d6ff2fd8753 test.gguf:tensor_290sha256 947e6b36e20f2cc95e1d2ce1c1669d813d574657ac6b5ac5196158d454d35180 test.gguf:tensor_291xxh64 e83fddf559d7b6a6 test.gguf:tensor_392sha1 a9cba73e2d90f2ee3dae2548caa42bef3fe6a96c test.gguf:tensor_393sha256 423b044e016d8ac73c39f23f60bf01bedef5ecb03c0230accd824c91fe86f1a1 test.gguf:tensor_394xxh64 1257733306b7992d test.gguf:tensor_495sha1 d7bc61db93bb685ce9d598da89717c66729b7543 test.gguf:tensor_496sha256 79737cb3912d4201384cf7f16a1a37ff7823f23ea796cb205b6ca361ab9e3ebf test.gguf:tensor_497xxh64 d238d16ba4711e58 test.gguf:tensor_598sha1 0706566c198fe1072f37e0a5135b4b5f23654c52 test.gguf:tensor_599sha256 60949be8298eced0ecdde64487643d018407bd261691e061d9e9c3dbc9fd358b test.gguf:tensor_5100xxh64 3fbc3b65ab8c7f39 test.gguf:tensor_6101sha1 73922a0727226a409049f6fc3172a52219ca6f00 test.gguf:tensor_6102sha256 574f4c46ff384a3b9a225eb955d2a871847a2e8b3fa59387a8252832e92ef7b0 test.gguf:tensor_6103xxh64 c22021c29854f093 test.gguf:tensor_7104sha1 efc39cece6a951188fc41e354c73bbfe6813d447 test.gguf:tensor_7105sha256 4c0410cd3c500f078ae5b21e8dc9eb79e29112713b2ab58a882f82a3868d4d75 test.gguf:tensor_7106xxh64 936df61f5d64261f test.gguf:tensor_8107sha1 c2490296d789a4f34398a337fed8377d943d9f06 test.gguf:tensor_8108sha256 c4401313feeba0261275c3b25bd2d8fe40ce04e0f440c2980ed0e9674c30ff01 test.gguf:tensor_8109xxh64 93fd20c64421c081 test.gguf:tensor_9110sha1 7047ce1e78437a6884337a3751c7ee0421918a65 test.gguf:tensor_9111sha256 23d57cf0d7a6e90b0b3616b41300e0cd354781e812add854a5f95aa55f2bc514 test.gguf:tensor_9112xxh64 5a54d3aad816f302 test.gguf113sha1 d15be52c4ff213e823cb6dd13af7ee2f978e7042 test.gguf114sha256 7dd641b32f59b60dbd4b5420c4b0f6321ccf48f58f6ae201a3dbc4a58a27c6e4 test.gguf115```116 117We can then use the normal check command which will by default check for the highest security strength hash and verify against that:118 119```bash120$ ./llama-gguf-hash --check test.gguf.manifest test.gguf121manifest test.gguf.manifest sha256 sha1 xxh64122sha256 c0510d38fa060c46265e0160a85c7243096b01dd31c2f355bdbb5516b20de1bd test.gguf:tensor_0 -
