[Acceleo] Maximum size of a module [message #1791182]

Hi !

Long time no see... ;)

Just a little question : I'm working with a project made by another person and I'm fixing some problems in a particularly big Acceleo module file. It contains more than 2200 lines of code, I've got several error popups since some days indicating an error about Acceleo and an exceeded maximum size of a string when I modify this file, but now if I try to modify this file, the whole Eclipse platform freezes definitively, but not the OS. The only solution is to kill this Eclipse process.

Do you know what is the cause of this problem ? Is this a problem caused by the size of the file, or a certain generated string in this module is too long ?

Thanks.

Best regards.

PS : I know that using a huge module file in Acceleo is not a good idea, but I can't move easily some of the templates/queries to another module because this is a module used by a lot of other ones.

I think it's a problem of memory of the Eclipse platform... if you confirm there is no size limitation in the Acceleo code.

Hi

2200 is large and so that might cause slow response, but it should not cause a freeze. Unless you are using a ten year old machine with limited memory, I would not expect 2200 lines to be a significant problem memory-wise.

There are many different parts of Eclipse that do not always play well together. Using something like Visual VM to get a thread dump of your freeze may provide some clues that may help you avoid the freeze and to raise an appropriate Bugzilla. Freezes are often difficult to reproduce, so if you have a reproducible one the developers may be 'grateful'.

Hi !

I increased the maximum memory used by the Eclipse platform and I haven't the problem anymore for the moment. But it may be possible a memory leak happens step by step, I restart sometimes the Eclipse platform to free its memory.
Nevertheless I try to avoid to make too big module files because the compilation may be long.

Best regards.
