Some Rust dependency issues prevent it from compiling #3

Open LiuMicheal opened 10 months ago

LiuMicheal commented 10 months ago

Hi, really excellent work! The research we were doing wanted to perform a performance comparison with mitosis, but we found that it had some Rust dependency issues that prevented it from compiling.

My environment: Ubuntu 18.04 4.15.0-46-generic MLNX_OFED_LINUX-4.9-3.1.5.0

After I completed all the instructions in mitosis-core/docs/setup.md. When I use rustc of nightly-2022-02-04-x86_64-unknown-linux-gnu, I get the following results:

root@liu-9:~/mitosis-core# make clean & make km [1] 88763 rm -rf mitosis-kms/Cargo.lock cd mitosis-kms ; python build.py fork rm -rf mitosis-kms/target

This error is easy to understand, so I switched to nightly-2022-11-03-x86_64-unknown-linux-gnu, which corresponds to rustc 1.67.

( I also found that rustc 1.68 and later versions cannot be used. For example, when I use nightly-2023-01-07-x86_64-unknown-linux-gnu, corresponding to rustc 1.68, an error will be reported:

root@liu-9:~/mitosis-core# make clean & make km [1] 88923 rm -rf mitosis-kms/Cargo.lock cd mitosis-kms ; python build.py fork rm -rf mitosis-kms/target

Caused by: process didn't exit successfully: rustc - --crate-name ___ --print=file-names --target x86_64-unknown-none-linuxkernel --crate-type bin --crate-type rlib --crate-type dylib --crate-type cdylib --crate-type staticlib --crate-type proc-macro --print=sysroot --print=cfg (exit status: 1) --- stderr error: Error loading target specification: Could not find specification for target "x86_64-unknown-none-linuxkernel". Run rustc --print target-list for a list of built-in targets

I confirmed in rustc's update log that the target "x86_64-unknown-none-linuxkernel" was indeed removed after 1.68. )

When I used nightly-2022-11-03-x86_64-unknown-linux-gnu (corresponding to rustc 1.67), I got the following running results:

root@liu-9:~/mitosis-core# make clean & make km [1] 89474 rm -rf mitosis-kms/Cargo.lock rm -rf mitosis-kms/target cd mitosis-kms ; python build.py fork

This error is also easy to solve. I modified split-debuginfo = 'off' in mitosis-core/mitosis-kms/fork/Cargo.toml. After that I ran it again using make clean & make km and a lot of errors appeared. I modified the mitosis-core/mitosis-kms/Kbuild

cd $(src)/$(TEST_PATH); CARGO_TARGET_DIR=../target $(CARGO) build -Z build-std=core,alloc --target=$(TARGET) --features "mitosis krdma-test cow use_rc " --no-default-features

I use it every time before compiling

cd mitosis-core/mitosis-kms/fork
rm ~/.cargo/registry/cache/github.com-1ecc6299db9ec823/* && cargo clean --target-dir ../target && rm Cargo.lock

To eliminate the impact of crate caching.

Why can't find crate for std? How should I modify it to make the compilation pass correctly? We have three students here who all hope to continue research based on mitosis. This is greatly appreciated!

( I manually modified the versions of many dependencies in xx.toml. Finally, I got the following results when I ran make km:

What should we do next, thank you very much!

wxdwfc commented 10 months ago

Can you please try the following:

  1. remove mitosis-kms/fork/Cargo.lock
  2. retry with our default toolchain, e.g., by setting rustup default nightly-2022-02-04-x86_64-unknown-linux-gnu. (Be sure to use a clean version from the git)

In general, we currently don't recommend modifying the tool chain. If you want a specific rust version to use, please start an issue and we can see whether we can support so, thanks.

LiuMicheal commented 10 months ago

Fine, when I use nightly-2022-02-04-x86_64-unknown-linux-gnu to try again, I meet this error:

warning: /root/mitosis-core/mitosis/Cargo.toml: dependency (x86_64) specified without providing a local path, Git repository, or version to use.

nightly-2022-02-04-x86_64-unknown-linux-gnu corresponds to rustc 1.60. regex-automata v0.4.3 seems to be an intermediate crate that some crates depend on during the compilation process. Its version is too high and cannot be compiled with rustc 1.60. Should I modify some versions?

wxdwfc commented 10 months ago

May I ask you which branch do you use?

LiuMicheal commented 10 months ago

Fine, main branch.

wxdwfc commented 10 months ago

It's quite weird. The main branch should work fine, and the fork does not rely on regex-automata.

Does the error happens when you build module with make km at the root path of the project on the main branch?

If the error still happens, can you check the dependencies tree of the built target? e.g., cd mitosis-kms/fork; cargo tree

wangtianxia-sjtu commented 10 months ago

That is a weird error. But can you please first remove .cargo/ and .rustup/ in your $HOME directory and then reinstall the rust toolchain. After that, run make clean && make km again with rust version nightly-2022-02-04-x86_64-unknown-linux-gnu. Be sure to use our latest version of main!

@wxdwfc When I build module with make km at the root path of the project on the main branch, the errors happened again. The mitosis project does not depend on regex-automata, but I feel that some other crates from crate.io need to depend on regex-automata in the new version, causing cargo build to introduce regex-automata when negotiating versions between various crates. Here is the cargo tree:

@wangtianxia-sjtu Sure, I confirmed that I am using the latest version of main. Firstly I use cd mitosis-core/mitosis-kms/fork; rm -r ~/.cargo/ && rm -r ~/.rustup/ to clear cache related to rust.

Then I use the commands in mitosis-core/doc/setmp.md: curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh source $HOME/.cargo/env rustup default nightly-2022-02-04-x86_64-unknown-linux-gnu rustup component add rust-src to reinstall the rust toolchain.

Then I use cd mitosis-core/mitosis-kms/fork; cargo clean --target-dir ../target && rm Cargo.lock to clear the intermediate results produced by the previous compilation. The error occurs again: error: package regex v1.10.2 cannot be built because it requires rustc 1.65 or newer, while the currently active rustc version is 1.60.0-nightly

In addition, I use rm ~/.cargo/registry/cache/github.com-1ecc6299db9ec823/* && cargo clean --target-dir ../target && rm Cargo.lock every time before restarting make clean && make km and found that there are other kinds of errors. For example: error: package crossbeam-utils v0.8.17 cannot be built because it requires rustc 1.61 or newer, while the currently active rustc version is 1.60.0-nightly

error: package memchr v2.6.4 cannot be built because it requires rustc 1.61 or newer, while the currently active rustc version is 1.60.0-nightly

error: package crossbeam-channel v0.5.9 cannot be built because it requires rustc 1.61 or newer, while the currently active rustc version is 1.60.0-nightly ...

Is it because the rustc 1.60 of nightly-2022-02-04-x86_64-unknown-linux-gnu is a bit old?

@LiuMicheal "Then I use cd mitosis-core/mitosis-kms/fork; cargo clean --target-dir ../target && rm Cargo.lock to clear the intermediate results produced by the previous compilation. The error occurs again:" Please try not remove the Cargo.lock to compile it: the version of regex-syntax described in our provided Cargo.lock should work with rustc-1.6.

LiuMicheal commented 10 months ago

Oh, I made a mistake, I shouldn't remove Cargo.lock and then let it regenerate. However, when I use the provided Cargo.lock with rustc-1.60 and *cd mitosis-core/mitosis-kms/fork; rm ~/.cargo/registry/cache/github.com-1ecc6299db9ec823/ && cargo clean --target-dir ../target and make km**, I got this error:

It seems that hashbrown caused a version conflict of once_cell. As for hashbrown in mitosis-core/deps, I am using the branch as shown in the picture, which is consistent with the main branch of mitosis. mitosis-deps

Even the cargo tree cannot be generated:

May be updating the hash brown version of KRCore to 0.12 may address the issue?

LiuMicheal commented 10 months ago

I use:

[dependencies]
...
# hashbrown = "0.9"
hashbrown = "0.12" # modified by me 2023-12-20
..

to update all toml in mitosis-core/deps/krcore. Then I use the provided Cargo.lock with rustc-1.60 and cd mitosis-core/mitosis-kms/fork; cargo clean --target-dir ../target and make km, I got this same error again:

Thank you for your information. Can you please further provide the complete cargo tree information so I can check which crates depend on once_cell? In my cargo tree, I only find hashbrown uses it.

LiuMicheal commented 10 months ago

Sure. However, when I use cd mitosis-core/mitosis-kms/fork; cargo tree command, I found the cargo tree cannot be generated with the error:

Thank you for your answers again and again.

wxdwfc commented 10 months ago

Thank you for your feedback! After some digging I found that it is caused by our lossy assignment of crate versions in KRdmaKit and also other projects. Sorry about that.

I have updated one Cargo.lock to fix it. Can you see it works here? Be sure to rename it to Cargo.lock and place it at mitosis-kms.fork/. Cargo-lock.txt

wxdwfc commented 10 months ago

Note that due to random version select of Cargo, the lock may not fix all the problem... but, if you meet another, please kindly remind me so: I can give you instruction on how to solve them :)

A complete fix requires some time (and we are working on this), but an on-demand fixes won't take much time. Thanks.

LiuMicheal commented 10 months ago

Thank you so much for instructions! @wxdwfc @wangtianxia-sjtu I am very interested in mitosis and it is my honor to join this project and contribute some updates to mitosis. I have a lot of new ideas that I’m trying out :)

wxdwfc commented 10 months ago

Thank you so much for your interests. Please kindly let us know if the above instructions fix your problem.
