[GitHub] [lucene] reta opened a new pull request, #12016: Upgrade ANTLR to version 4.11.1
reta opened a new pull request, #12016:
URL: https://github.com/apache/lucene/pull/12016
Signed-off-by: Andriy Redko <an...@aiven.io>
### Description
The Apache Lucene is using quite old version of ANTLR 4.5.1-1. By itself, it is not a showstopper, but more profound issue is that some ANTLR 3.x bits are used [1]. Since ANTLR 4.10.x (or even earlier), the compatibility layer with `3.x` release line has been dropped in `4.x` (see please [2]), which makes Apache Lucene impossile to be used with recent ANTLR 4.10.x+ releases [3]. The sample exception is below.
```
> java.lang.UnsupportedOperationException: java.io.InvalidClassException: org.antlr.v4.runtime.atn.ATN; Could not deserialize ATN with version 3 (expected 4).

@reta I remember doing this adds overhead, that's why it is a boolean there. so it really just needs to be something we do from tests. for example it could be a package-private setter or similar?

In general, sorry if i discouraged before, it is really just a frustrating situation
If you get stuck, just leave the PR open. I will try to dig into this too, I have been through it before. I do agree we can't stay on old releases forever.
But the crazy shit they did between antlr 3.x and 4.x caused me pain:
* made the mistake of not spelunking thru antlr guts to figure out how to prevent performance traps
* had users report performance bugs (in all cases it was some grammar tweak to fix)
* fix these performance bugs in subsequent releases
* get frustrated with the leniency and figure out how to make the shit picky again.
So I don't wish that on anyone. Currently the expressions is great because it is simple and performs well: Users can represent needs in a simple javascript-like fashion and trust that it has same performance as writing custom java code.

I also dont understand the issue where ppl think they can modify arbitrary versions of lucene dependencies.
Can we specify our dependencies in a different way (e.g. exact version) in our maven stuff so this won't happen? e.g. you can do this in python, and specify that you depend on `antlr == x.y.z` rather than just depend on `antlr`.

Technically - easy to do. Question is whether we want to do it (I don't see any problems here).

I will check it out and inspect the coverage report from .js tests and see if there are any holes. If i find them I will push more tests. I am just really paranoid about some of the slow things antlr4 will do, having fought thru these issues with @jdconrad once before.

@rmuir first pass over pickiness, all tests are now run w/o diagnostics listener (picky / not picky mode), the rough observations so far are encouraging, there are no significant changes in the test duration between these two modes (some random timings below):
I am moving further to compare the numbers against `main` and to conduct more precise measurements.

> You can - I think what Uwe is describing is a problem for downstream projects where Lucene has antlr x.y.z and some other dependency has antlr a.b.c - then namespaces clash and the conflict is not easily resolved. Classloader separation is possible, of course, but it's hardly an easy alternative. :)

> I personally don't mind shading artifacts but I do agree they are a pain... even tracking down which version a project is actually using is a problem then (because shaded artifacts don't manifest their versions as clearly as a maven dependency). Corporate environments will hate them for legal reasons (for reasons Rob mentioned).
Hi,
as said before this was just a suggestion from my experience with forbiddenapis with some artifacts like "ASM" and "ANTLR". They are always a pain. From the secruity perspective there are problems, but you can also see it like "code copied" - we can of course also do this, but that's a lot more hassle.
What you can always do: Offser a shaded version without those 2 dependencies as a seüparate artifact. Often seen on maven as "uber" or "shaded" behind version number. If you want to use shaded version, you know consequences.
Setting exact version in Maven POMs is not possible, unfortunately. Maven has some tricks (it wont silently upgrade across major versions, but bugfix releases are automatically applied). I don't know exacty how this is handles by Maven resolver.
My idea would be: publish "lucene-expressions-shaded.x.y.z" in addition.

another way to say it: shading is a terrible, TERRIBLE idea and you only hear about it in java, because java is the only language with developers that are bad enough to consider it.
Please, let's not talk about it ever again.

I agree with @rmuir that having an ambiguity check for tests similar to Painless would be great for expressions. I'm a bit surprised this change didn't require much additionally to the regeneration of the lexer/grammar. One other thing I'm curious about is if this suffers from the same issue that Painless did with multiple nested conditionals (https://github.com/elastic/elasticsearch/pull/52056). So that may be something else worth adding a test for. Thanks for looking into upgrading this @reta!

Hi, I agree with all Robert say. I would also like to make another suggestion (that could also be applied when this has been fixed). To me it looks like a bad decission of antlr, that the tool compiles code and creates some Java/Class files but at runtime it also needs some dependency JAR in exactly the correct version. This is a problem for a library like lucene that gets included into other projects. The same also applies for ASM, although this is no longer a big problem anymore, because ASM's APIs are now very stable and it does not matter if a project uses ASM 8 or ASM 9 if minimum requirements are guaranteed (so the user has more flexibility).
In contrast javacc does not have the problem, because javacc or jflex generates all of the code and you don't need any runtime library to execute and access the AST.
In Lucene both (ANTLR and ASM) are dependencies of one artifact: lucene-expressions, so it is only a real problem there. My suggestion would be: Let's shade the ANTLR (and possibly also ASM - until the JDK-included bytecode generator is out of incubation/preview) into the JAR file. With ASM this was hard to do but with Grade it is quite easy. Just add another configuration with those two dependencies and use the "Gradle Shadow Plugin" (https://imperceptiblethoughts.com/shadow/) to transform their package names into the Lucene namespace.
I know some people don't like this, but I had exactly the same problems with ASM in the forbiddenapis plugin and shading ASM in there was the only way to work around different, old, incompatible versions of ASM inside Maven or Gradle's classpath, while forbiddenapis always needeing the newest one.
If you like I could make a PR to demonstrate the shading for Lucene's Gradle build in Expressions. @dweiss : What do you think? Of course we should not use shading anywhere else, but ANTLR and ASM are the candidates that always bring problems. Their size is also small so the overhead is small, but you have a consistent package that is unlikely to break when other projects use different library versions.

> One other possibility would be to hand-roll the expression lexer/parser. This would get rid of the need for any additional dependencies and generated code. From what I can tell the API has been stable for a long time, so I don't think there would be a problem with maintenance. This would have the added benefit of likely improved performance as ANTLR isn't the fastest, and potentially better error messages.

here is coverage report using the current antlr. I guess i dont know why so much is missing here:
https://ci-builds.apache.org/job/Lucene/job/Lucene-Coverage-main/618/jacoco/org.apache.lucene.expressions.js/
But yeah, if we exercise the possibilities of grammar from tests, AND tests use picky mode, then build will fail if grammar is ambiguous. It is definitely a PITA compared to antlr 3 :(

Simple package-private `static` method to turn on the pickiness should do it.
I don't want to see 100 new constructors/abstractions added with booleans, just because antlr made a bad decision. Our APIs should not have to suffer for it.
Don't care what java developers or static analysis tools or whatever else wants to say about it: minimal abstractions here.

One other possibility would be to hand-roll the expression lexer/parser. This would get rid of the need for any additional dependencies and generated code. From what I can tell the API has been stable for a long time, so I don't think there would be a problem with maintenance. This would have the added benefit of likely improved performance as ANTLR isn't the fastest, and potentially better error messages.

we don't need to parameterize the pickiness IMO, we can just turn it on in these tests. Thanks for getting this hooked up. I will look at your branch and try to play with it.

> Can we specify our dependencies in a different way (e.g. exact version) in our maven stuff so this won't happen? e.g. you can do this in python, and specify that you depend on antlr == x.y.z rather than just depend on antlr.
You can - I think what Uwe is describing is a problem for downstream projects where Lucene has antlr x.y.z and some other dependency has antlr a.b.c - then namespaces clash and the conflict is not easily resolved. Classloader separation is possible, of course, but it's hardly an easy alternative. :)
I personally don't mind shading artifacts but I do agree they are a pain... even tracking down which version a project is actually using is a problem then (because shaded artifacts don't manifest their versions as clearly as a maven dependency). Corporate environments will hate them for legal reasons (for reasons Rob mentioned).

I am a bit afraid because those blobs with DFAs growed quite a lot in the patch. So yes, let's review how it behaves.

personally i am against the shading. I think it is a huge antipattern, it hides third-party artifacts completely. think about someone trying to do security or license audit and they have "secret dependencies" hidden from view, as an example.
I don't understand the issue myself. if you want to use different antlr version in two places just use two classloaders. thats what we did in elastic/opensearch.
but like i said, i'm not opposed to upgrading IF concerns about the new version are taken care of.

I feel that if we publish a shaded jar we become guilty of "contributing to the delinquency" of terrible supply chain management, by hiding third party dependencies and their versions from view. It causes problems for checkers and even humans if there were ever some issue with one of the dependencies (example log4j). They might miss it entirely and get hacked, as an example. Then they will be mad at us for shading in the first place, even though its arguably their fault because they used a shaded jar.
Let's just not hand them the gun.

Review Comment:
I agree with Uwe, let's move to a boolean (actually only need one package-private ctor with the boolean, the way the new base CompilerTestCase class works).
If we have more options to this thing later, we can deal with the issue at that time. It is all package-private anyway.
