AttributeError: 'Unlexer' object has no attribute 'WHEN' #5

We're facing the following error when generating our grammar:

The above exception was the direct cause of the following exception:

@marcospassos Could you provide the way you've built the grammar and how the tests were generated? I've generated a fuzzer from the example you pasted and it seemed to work fine.

The commands I used:

grammarinator-process TestLexer.g TestParser.g -o test
grammarinator-generate -l test/TestUnlexer.py -p test/TestUnparser.py -r domain -n1

However, one thing is suspicious: your trace seems to use an unparser named BaseCclUnparser which is not the same as the example. So maybe something is missing from the repro grammar.

marcospassos · 2017-07-08T20:54:07Z

Ok, pretty weird. It looks like the error only happens if you execute the command out of the folder containing the grammars. Try it from the parent folder:

grammarinator-process grammar/TestLexer.g grammar/TestParser.g -o test

Now, I can generate it running the command inside the dir. However, now I'm getting another error:

grammarinator-generate -l test/TestUnlexer.py -p test/TestUnparser.py -r domain -n 100

renatahodovan · 2017-07-08T21:10:02Z

@marcospassos This is because your grammar is recursive and there is no recursion limit set. You can define it with the -d command line flag. Probably this should also be more emphasised in the documentation.

marcospassos · 2017-07-08T21:14:34Z

But it's not even documented in the command line signature. What does this flag do exactly?

grammarinator-generate [-h] -p FILE -l FILE -r NAME
                              [-t LIST [LIST ...]] [-j NUM] [-o FILE] [-n NUM]
                              [-v]

About the problem related to the working dir, is it the expected behavior?

marcospassos · 2017-07-08T21:16:40Z

Looks like this flag does not exist in the version that I'm using:

rammarinator-generate -l test/TestUnlexer.py -p test/TestUnparser.py -r domain -n 100 -d 10
usage: grammarinator-generate [-h] -p FILE -l FILE -r NAME
                              [-t LIST [LIST ...]] [-j NUM] [-o FILE] [-n NUM]
                              [-v]
grammarinator-generate: error: unrecognized arguments: -d 10

marcospassos · 2017-07-08T21:25:37Z

Ok, I found it on master (the version installed using pip is not in sync).

renatahodovan · 2017-07-08T21:26:19Z

@marcospassos Seems that we are using different versions. The support for recursion limit was added in 85ca911. The grammarinator-generate --version should show grammarinator-generate 17.5r.
The -d argument appears in the help message of grammariantor-generate:
-d NUM, --max-depth NUM maximum recursion depth during generation (default: inf).
My guess is that something was messed up around versions when you installed grammarinator from pip and then reinstalled from source.

renatahodovan · 2017-07-08T21:29:13Z

@marcospassos Yes, pip is only updated when a new version is released. Between two releases the new features are only available in the master.

marcospassos · 2017-07-08T21:34:33Z

I'm having a bad time trying to make it work with our grammar. I've reinstalled everything from scratch, but the latest version (master) throws new errors now:

marcospassos · 2017-07-08T21:37:46Z

The same errors do not occur in the version installed using pip.

renatahodovan · 2017-07-08T21:41:55Z

@marcospassos This is a bug indeed. Thanks! I will fix it. The problem is that EOF is a builtin ANTLR token that should have been handled specially when calculating the distances.

marcospassos · 2017-07-08T21:48:06Z

@renatahodovan thanks! Looking forward try a version that works with our grammar!

About the problem related to the working dir, is it the expected behavior?

As a side note, it's important to allow generating tests on CI servers.

renatahodovan · 2017-07-08T22:00:15Z

@marcospassos If I'm right, then 2554246 has fixed the EOF issue and your example should work after updating to the latest master.

marcospassos · 2017-07-08T22:02:33Z

renatahodovan · 2017-07-08T22:03:53Z

@marcospassos The other question about the working dir. I tried to run the example from different directories, but could not reproduce it. So could you rephrase it please, 'cos I'm not sure I understand the problem.

renatahodovan · 2017-07-08T22:05:55Z

Hm... The assertion is weird. Could you give a repro about the failing grammar?

marcospassos · 2017-07-08T22:12:13Z

I'm afraid not. The message is very unclear about the reason it's failing (the grammar has 1000+ lines). On the other hand, I can't publish the grammar because it's a proprietary language. Is there anything else I can do to help you?

renatahodovan · 2017-07-08T22:40:33Z

The assert means that the grammar has an alternation with an alternative that has an infinite depth. This could be because of an undefined rule reference or an infinite recursion, for example. One thing you can try is to put a print into the process.py:357 printing the value of the rule_name variable. This way you will know which rule has the problematic alternation and maybe can you create a short repro case without publishing the whole proprietary grammar.

marcospassos · 2017-07-08T22:56:32Z

Hm... it does not make sense. The last rule it prints is IDENTIFIER, that consists only of a list of keywords that are also identifiers:

identifier
    : IDENTIFIER_NAME
    | A | B | C | D | E | F | G | H | I | J | K | L | M
    | N | O | P | Q | R | S | T | U | V | W | X | Y | Z
    ...
;

I can't reach any conclusion about that. This grammar works pretty well in Java, so I don't think it is a problem in the grammar definition (any invalid reference would not compile). Besides this, this issue does not occur in the version available through pip. Is it possible to track the changes since that version?

renatahodovan · 2017-07-08T23:06:14Z

The issue is related to the recursion limit feature which is not part of the pip version, this is why that version works.
I didn't try to refer that the grammar is wrong, just trying to figure out what's going on.
Just to make sure, the printed IDENTIFIER is the same as the lower-case identifier in the pasted rule?

marcospassos · 2017-07-08T23:07:26Z

My fault, it is in lower case:

renatahodovan · 2017-07-08T23:22:05Z

Alright. The issue means, that the minimum distance from the 16. alternative of the identifier rule is infinite. From the example above it's probably a token reference to a letter definition. My last guess is that this definition is lost somewhere in the import chain. So it would be useful if you could describe how the letters are available from the grammar containing the identifier rule (I mean whether it's immediately in the lexer or it's imported somehow)?

renatahodovan · 2017-07-08T23:39:18Z

Okay, I've may found a reproduction case. I try to come up with a solution and will see if that solves your issue too.

marcospassos · 2017-07-08T23:39:46Z

@renatahodovan I don't think the problem is in the identifier rule because I just removed all other rules, leaving only identifier, and it worked. I've also double checked all alternatives in identifier and all refs exist.

marcospassos · 2017-07-08T23:40:24Z

Okay, I've may found a reproduction case. I try to come up with a solution and will see if that solves your issue too.

\o/

renatahodovan · 2017-07-09T22:24:05Z

@marcospassos I think (or hope) that the issue has been eliminated on the current master. Please verify if it solves your problem too. And don't hesitate to send a report if you find further bugs.

marcospassos · 2017-07-10T00:10:22Z

@renatahodovan it worked, thanks!

Any guess?

Seems that logicalOrExpression calls itself in an infinite recursion. Could you please show how that single rule looks like?

marcospassos · 2017-07-10T11:17:39Z

hi @renatahodovan!

Sure, although it does not recurse infinitely:

logicalOrExpression
    : logicalOrExpression logicalOrOperator logicalAndExpression
    | logicalAndExpression
;

logicalAndOperator
    : DOUBLE_AND
    | AND
;

logicalAndExpression
    : logicalAndExpression logicalAndOperator logicalAndExpression
    | quantifierExpression
    | testExpression
;
...

@marcospassos I've found a possible reason of the failure. Please try the latest master whether it solves your issue. Otherwise, please open another bug entry, since this one is getting overloaded :)

@renatahodovan still no success. I've opened the issue #6 to discuss the new issue.
