error: code too large for try statement + java heap [message #1861217]

Hi,
I am using Xtext to generate java code for a huge mysql grammar. I am facing a java heap error, even after increasing the Xms/Xmx size. I tried ti hide a subset of my big set of keywords which made my generation goes smoothly. However, when I use Antlrworks to debug my grammar I end up with a "code too large for try statement" error. Splitting my grammar doesn't work either. Let's say I have a rule with a big set of keywords which can be IDs named KeywordsCanBeId:
1- Should I define these keywords as rules or terminals?
2- Should I split this rule to subrules.? and how should I chose the number of keyword alternatives in each subrule?
3- What is the best way to get rid of these issues when dealing with rules that containes a big set of keyword alternatives (R:A|B|C|.....)?
thank you for your help

I fear this cannot be generally answered
One question eg can be: do you really need to bake everything into the grammar
In which code does the problem actually happing
Do you use the splitting options the parser generator options in the workflow

I am not sure whether splitting my grammar is necessary or not. Here is the part of the grammar (i.e., big rules) where the generation results in a java heap space exception:

I tried to split these rules into smaller subrules but nothing changed. I noticed that defining these keywords as terminals instead of rules consumes less memory. I tried to extend the file by splitting it into two grammars but nothing fixed. Here is the headers of each xtext file:
Quote:

grammar org.xtext.metamodel.sql.SQL with org.xtext.metamodel.sql.SQL2
generate sQL "http://www.xtext.org/metamodel/sql/SQL"
Root:

and
Quote:

grammar org.xtext.metamodel.sql.SQL2 with org.eclipse.xtext.common.Terminals
KeywordsCanBeId :

Here is the Generator.mwe2 langage part I used with both the one file grammar and the two files grammar:
Quote:

language = StandardLanguage {
name = "org.xtext.metamodel.sql.SQL"
fileExtensions = "sql"

serializer = {
generateStub = false
}
validator = {
// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
// Generates checks for @Deprecated grammar annotations, an IssueProvider and a corresponding PropertyPage
generateDeprecationValidation = true
}

parserGenerator = {
debugGrammar = true
options = auto-inject {
classSplitting = true
casesPerSpecialStateSwitch= "200"
fieldsPerClass = "200"
methodsPerClass = "200"
}
}
junitSupport = {
junitVersion = "5"
}

I tried to hide some parts of these two long rules till I got a succussful artifacts generation. But when I degug the grammar using Antlrworks I get the "code is too long in try statement" exception:

An what is the reason these need to be keywords ?

Besides that a real reproducer might help.
Don't see any direct keywords in what you have shared

Hi Christian,
Can you elaborate on the reproducer which I am not familiar with? I am reusing an antlr-based mysql grammar. There are some keywords which can be used as identifiers.

Eg why is there a keyword for all the functions
Why don't you just parse an id and implement the validator to check if it is a valid function

With reproducer I mean something I can copy and paste to see the actual error myself

Here is a reproducer, it is a messy and a reduced version of my huge grammar. I hope it gonna help. When I use Antlrworks, after I hid the Keywordscanbeid rule, it shows "code is too large" error. When I reintegrate this rule in the grammar it results in a "java heap space" error.
As for why this rule is there, it is because some mysql-specific keywords can be recognized as identifiers. I think I should get rid of this troublesome rule and its pairs.

Hi, i fear i have no clue how to solve this
maybe there are some antlroptions to overcome this

your grammar has a billion => to overcome ambiguities.
also you seem to have all keywords as datatype rules.

where is this grammar coming from?

You are right, this code needs to be refactored. I can reduce the number of => operators I used to avoid ambiguity, but I am more concerned right now with what is causing the "code is too large" and "Java heap space" errors since the => operators and ambiguous rules are not probably the cause. As I mentioned before, I am reusing an Antlr-based grammar of MySQL.

I refactored my code but some ambiguities are unavailable. I used the => to get a successful artifact generation. However, I end up with a code for the initializer is exceeding the 65535 bytes límit error in the InternalSQLParser class. Is there a programmatic solution to this?

Hi, I figured out that my grammar generates big arrays of the name dfa. Is there a way to avoid this or to split these arrays?

Hello Sohab!

I think it would be much easier if you would follow the suggestion of Christian:

Quote:

Hope that helps!
