What are you smoking? Shallow clones don't modify commit hashes.
The only thing that you lose is history, but that usually isn't a big deal.
--filter=blob:none
probably also won't help too much here since the problem withnode_modules
is more about millions of individual files rather than large files (although both can be annoying).From github's blog:
Maybe the hashes aren't different, but the important part is that comparisons beyond the fetched depth don't work: git can't know if a shallowly cloned repo has a common ancestor with some given commit outside the range, e.g. a tag.
Blobless clones don't have that limitation. Git will download a hash+path for each file, but it won't download the contents, so it still takes much less space and time.
If you want to skip all file data without any limitations, you can do
git clone --filter=tree:0
which doesn't even download the metadataYes, if you ask about a tag on a commit that you don't have git won't know about it. You would need to download that history. You also can't in general say "commit A doesn't contain commit B" as you don't know all of the parents.
You are completely right that
--depth=1
will omit some data. That is sort of the point but it does have some downsides. Filters also omit some data but often the data will be fetched on demand which can be useful. (But will also cause other issues likeblame
taking ridiculous amounts of time.)Neither option is wrong, they just have different tradeoffs.
But that's my point: instead of things weirdly not working, they will work instead.
