Convert build system to Bazel. #2887

robertnishihara · 2018-09-15T07:36:32Z

It seems like using Bazel (https://github.com/bazelbuild/bazel) would improve our build system in a lot of ways.

@rshin did an early version of this a long time ago in ray-project/ray-legacy#408. @ericl, @concretevitamin, @pcmoritz have all used Bazel I believe and are proponents. @rsepassi and @dbieber have recently worked on this and have a good sense of what is involved.

Any thoughts about this? Any drawbacks to be aware of?

Will CMake script be retired or will both ways be kept? Currently, there are duplicated building for thirdparty libraries, e.g. zlib for Arrow and Parquet, etc. Avoiding duplicated building may improve the building time.

Hi @robertnishihara ,
actually, while I was working on cmake, I was confused with two problems:

how to manage dependency and its transitive dependency in cmake.
how to package and deploy.

I ever referred to tensorflow project to find out cmake best practice. And draw a principle for thirdparty dependency: ExternalProject only.

In maven, which is the cornerstone, it has maven center repository and local repository. It helps manage all downloaded jars and you can use them in your maven project.

So when it comes to cmake, cmake should also be able to reuse the downloaded dependencies. I would suggest to use FindXXXX.cmake to speed up the (second) build process. However, I still can not deal with the transitive problem unless you wrote each ExternalProject.

So ... for c++ dependency, I need a mechanism to support it. cmake is not enough.

I did not package ray yet, because it is already packaged by python wheels. But for cmake package mechanism, which is based on gcc library links, I found in tensorflow, it uses static library instead of dynamic for thirdparty libraries. em... I have to admit it is quite reasonable.

I have not used bazel yet, but I found it is easy to understand once you know cmake. And it has the ability to support other languages, which is good for python and java. Also It has better third-party dependency management.

The key problem may be it is too new to cooperate with IDEs, which for me it is important to debug.

And at last, if you'd like, we can keep cmake and bazel both solutions. In tensorflow, it has cmake in a standalone directory which contains the whole tensorflow project.

robertnishihara · 2018-09-17T03:58:48Z

@guoyuhong @chuxi We could potentially keep around cmake for IDE reasons, but I think it would be substantially less work to just retire cmake. @chuxi where is the TensorFlow directory that you're talking about?

yes, transitive dependency problem. And I am considering to write some findXXX modules, which support to find a directory which contains all dependency.

we define a cmake property: CMAKE_EXTERNAL_HOME, by default it is ${CMKAE_CURRENT_BINARY_DIR}/build/external. And then we write some findXXX.cmake modules based on the directory.

Then in the ${CMAKE_EXTERNAL_HOME}, all dependencies are kept and the user could get benefit from it.

And for user he can change it to his own directory. So for each build he can get the benefit from local pre build projects.

tensorflow/contrib/cmake the directory has cmake files for tensorflow, I read and found it works, but may not be always updated as bazel.

raulchen · 2018-09-17T04:15:33Z

I don't have much experience with Bazel. From its web site https://www.bazel.build/, it doesn't claim support for Python. Would this be a problem for us?
Will buck (https://buckbuild.com/) also be an option? It's similar to bazel. I don't have a in-depth comparison for buck and bazel. But IFAIK, buck has good support for C++, python and java.

concretevitamin · 2018-09-17T04:42:09Z

Bazel supports Python: https://docs.bazel.build/versions/master/be/python.html and is backed by Google.

ericl · 2018-09-17T04:43:01Z

I looked a bit into the currently available python support:

Bazel provides a set of basic rules for Python components and unit tests: https://docs.bazel.build/versions/master/be/python.html#py_test
They have experimental support for PyPI library dependencies: https://github.com/bazelbuild/rules_python
It also looks straightforward to use a shell rule or custom rule to build wheels, for example, here is a such a custom rule: https://github.com/horia141/bazel-pypi-package

Overall it looks workable, though it would probably make sense to tackle Python build conversion incrementally since things aren't fully baked here.

Re: buck, my impression is that does not have much adoption outside of facebook.

rsepassi · 2018-09-17T23:08:40Z

We've got all C++ dependencies building internally at v0.5.2. I've opened a PR with a partial BUILD file that still needs the external stuff to be added. Totally fine to not merge that, but thought I'd send along so that you all have a starting point.

rsepassi · 2018-09-17T23:10:29Z

Ideally the code would be restructured so that there's a BUILD file per directory and things are a bit more decoupled. But that would be a lot more work to disentangle stuff. The BUILD file in the PR was written so as to require no/minimal changes to the source given the cmake build.

rsepassi · 2018-09-18T00:23:48Z

For the external dependencies, it looks like each would have a new_git_repository rule to download them.

A genrule could be used to call the cmake command (or whatever bash command needs to be called to build it).

A cc_library can then wrap all the compiled units, or if it's easy you can write BUILD rules for them (gtest example).

mitar · 2018-09-27T20:33:11Z

I had quite some issues in the past installing Bazel to compile some libraries on some supercomputing clusters (like Berkeley's Savio) because it depends on Java. And then you have this problem that to compile a simple thing which does not use Java, you have to get Java onto the system. Was not impressed.

robertnishihara · 2018-12-04T19:14:12Z

@pcmoritz, if we use Arrow binary artifacts instead of compiling Arrow, then the switch to Bazel will probably be much easier.

Note

This requires frequent (e.g., nightly) and persistent binary artifacts from Arrow.
This makes it harder to test changes to Arrow in Ray.

rsepassi · 2018-12-04T19:41:43Z

Can't remember if I had previously shared this, but in case it's relevant to what you're thinking about, Bazel genrule <https://docs.bazel.build/versions/master/be/general.html#genrule> can wrap cmake commands.

To interface with cmake, see also https://github.com/bazelbuild/rules_foreign_cc (cc @irengrig).

robertnishihara · 2018-12-04T19:55:52Z

Thanks @rsepassi and @laurentlb!

robertnishihara · 2019-02-23T20:00:20Z

Mostly done in #3898. We still aren't using Bazel to build our wheels because the Bazel build upgraded Arrow, which is causing other issues (see #4129).

zbarry · 2019-02-25T19:41:23Z

Might already know this, but just in case, I think Bazel wasn't added as a dependency yet on master, so this breaks compilation unless the user explicitly installs it before running pip install -v -e .

zbarry · 2019-02-25T19:58:27Z

Hmm, I haven't seen this one. What happens if you do curl -sL https://github.com/antirez/redis/archive/5.0.3.tar.gz manually and try to extract the file with tar xz --strip-components=1 -C .? Does it give the same error?

zbarry · 2019-02-28T18:57:56Z

Sorry for delay. Found something really weird. Using the system curl, it works just fine. The (my) anaconda curl is what is "broken".

System: CentOS 7
uname -r: 3.10.0-693.21.1.el7.x86_64

[user@host ~]$ /usr/bin/curl --version
curl 7.29.0 (x86_64-redhat-linux-gnu) libcurl/7.29.0 NSS/3.28.4 zlib/1.2.11 libidn/1.28 libssh2/1.4.3

With anaconda3:

[user@host ~]$ which curl

It appears that curl -sL https://github.com/antirez/redis/archive/5.0.3.tar.gz just returns instantly with the anaconda 3 curl, with no content. For what it's worth, curl https://google.com -sL seems to spit out the google homepage to the terminal just fine with this same curl... weird.

E: ok, same problem / error message either way. Not knowing much about curl, it appears that the curl blah -sL just spits the output straight to the terminal (at least for my system / anaconda curl versions). If tar is expecting a file on disk instead of a stream based on how the build system is set up (no idea), I guess this might be the problem?

Any idea what may be happening? Weird that none of the previous curls fail until this one is hit. Would be nice to be able to compile bleeding-edge Ray versions

robertnishihara · 2019-03-04T19:03:24Z

Hm, for me curl -sL "https://github.com/antirez/redis/archive/5.0.3.tar.gz" also appears to return nothing, but the composition curl -sL "https://github.com/antirez/redis/archive/5.0.3.tar.gz" | tar xz --strip-components=1 -C . seems to do the right thing. This is with

$ which curl

zbarry · 2019-03-04T20:43:54Z

Your composition works for me, too, so even more confused now... is that the actual command being run by the build system, though?

robertnishihara · 2019-03-05T19:32:05Z

The remaining issues that need to be addressed before we deprecate cmake are #4273 and #4272.

robertnishihara · 2019-03-05T19:34:19Z

@zbarry I've seen the same error that you mentioned in our CI (on Travis) nondeterministically. It's possible that we need to just retry that command if it fails, though it'd be nice to have a more reliable approach.

zbarry · 2019-03-05T19:36:10Z

Gotcha. Let me get a fresh repo + conda env going and see what happens

zbarry · 2019-03-05T20:55:30Z

Hmm. At least in my case, I don't think the issue is a Monte Carlo curl.

I changed the bazel build line in build.sh to be:

bazel build //:ray_pkg -c opt --sandbox_debug --verbose_failures

which gave the exact command being executed. Maybe this is helpful(?). Here, you can see clearly that the command run is indeed curl -sL "https://github.com/antirez/redis/archive/5.0.3.tar.gz" | tar xz --strip-components=1 -C ., which works if I just paste into a terminal.

Hmm, I don't really see what is going wrong here. As a workaround, do you want to try replacing curl by wget and see if that fixes the problem?

zbarry · 2019-03-05T21:11:17Z

Ugh. I figured it out because wget gave me a useful error message. For whatever reason, that particular genrule is not pulling my http_proxy and https_proxy environment variables in, so github.com is not being resolved... I added them explicitly to the rule via export http_proxy=blah, and Ray built to completion. Is there a way to make sure these vars (I guess all the user's environment vars?) are present in the build environment?

pcmoritz · 2019-03-05T21:19:59Z

So not including your environment variables is actually a feature of Bazel (it's supposed to create the same build environment on every machine, this also means having a well-defined set of environment variables).

For use cases like this, you can use the following functionality I think: https://bazel.build/designs/2016/06/21/environment.html

If this helps, contributing a patch that allows to pass arguments from setup.py into bazel would be welcome!

Actually, I think putting the option into your .bazelrc would also work and is probably a better solution.

Thanks. Will look into modding .bazelrc. Those --sandbox_debug --verbose_failures flags might be worth adding into the build script, by the way!

Ok. Good to go. Since that Bazel env config page is not super explicit about how to specify vars to pass through the build environment, for others that have the misfortune of living life behind a proxy, just plop these into ~/.bazelrc:

build --action_env=http_proxy
build --action_env=https_proxy

@zbarry thanks for the fix, @jliagouris just ran into the same problem and your suggestion worked.

@zbarry Thanks for the suggestion, I added the flags here: #4278
