Subject: [PATCH v8 5/6] unpack-objects: unpack_non_delta_entry() read data in a stream
Date: Sat, 8 Jan 2022 16:54:18 +0800 [thread overview]
Message-ID: <20220108085419.79682-6-chiyutianyi@gmail.com> (raw)
In-Reply-To: <20211217112629.12334-1-chiyutianyi@gmail.com>
From: Han Xin <hanxin.hx@alibaba-inc.com>
We used to call "get_data()" in "unpack_non_delta_entry()" to read the
entire contents of a blob object, no matter how big it is. This
implementation may consume all the memory and cause OOM.
By implementing a zstream version of input_stream interface, we can use
a small fixed buffer for "unpack_non_delta_entry()". However, unpack
non-delta objects from a stream instead of from an entrie buffer will
have 10% performance penalty.
$ hyperfine \
--setup \
'if ! test -d scalar.git; then git clone --bare
https://github.com/microsoft/scalar.git;
cp scalar.git/objects/pack/*.pack small.pack; fi' \
--prepare 'rm -rf dest.git && git init --bare dest.git' \
...
Summary
'./git -C dest.git -c core.bigFileThreshold=512m
unpack-objects <small.pack' in 'origin/master'
1.01 ± 0.04 times faster than './git -C dest.git
-c core.bigFileThreshold=512m unpack-objects
<small.pack' in 'HEAD~1'
1.01 ± 0.04 times faster than './git -C dest.git
-c core.bigFileThreshold=512m unpack-objects
<small.pack' in 'HEAD~0'
1.03 ± 0.10 times faster than './git -C dest.git
-c core.bigFileThreshold=16k unpack-objects
<small.pack' in 'origin/master'
1.02 ± 0.07 times faster than './git -C dest.git
-c core.bigFileThreshold=16k unpack-objects
<small.pack' in 'HEAD~0'
1.10 ± 0.04 times faster than './git -C dest.git
-c core.bigFileThreshold=16k unpack-objects
<small.pack' in 'HEAD~1'
Therefore, only unpack objects larger than the "core.bigFileThreshold"
in zstream. Until now, the config variable has been used in the
following cases, and our new case belongs to the packfile category.
* Archive:
+ archive.c: write_entry(): write large blob entries to archive in
stream.
* Loose objects:
+ object-file.c: index_fd(): when hashing large files in worktree,
read files in a stream, and create one packfile per large blob if
want to save files to git object store.
+ object-file.c: read_loose_object(): when checking loose objects
using "git-fsck", do not read full content of large loose objects.
* Packfile:
+ fast-import.c: parse_and_store_blob(): streaming large blob from
foreign source to packfile.
+ index-pack.c: check_collison(): read and check large blob in stream.
+ index-pack.c: unpack_entry_data(): do not return the entire
contents of the big blob from packfile, but uses a fixed buf to
perform some integrity checks on the object.
+ pack-check.c: verify_packfile(): used by "git-fsck" and will call
check_object_signature() to check large blob in pack with the
streaming interface.
+ pack-objects.c: get_object_details(): set "no_try_delta" for large
blobs when counting objects.
+ pack-objects.c: write_no_reuse_object(): streaming large blob to
pack.
+ unpack-objects.c: unpack_non_delta_entry(): unpack large blob in
stream from packfile.
* Others:
+ diff.c: diff_populate_filespec(): treat large blob file as binary.
+ streaming.c: istream_source(): as a helper of "open_istream()" to
select proper streaming interface to read large blob from packfile.
