Documentation Bug: wrong parameter type for `isfixingrevision()`

[Eddie Santos]

From http://boa.cs.iastate.edu/docs/dsl-functions.php:

isfixingrevision (rev: Revision) : bool

However, as demonstrated by some examples [1] [2], its signature is actually:

isfixingrevision (rev: string) : bool

(because it takes in ChangedFile.log: string).

Also, more information on isfixingrevision() would be nice. Does it implement the regular expressions and heuristics (i.e., syntactic confidence) in [3]?

 [3]

J. Śliwerski, T. Zimmermann, and A. Zeller, “When Do Changes Induce Fixes?,” in Proceedings of the 2005 International Workshop on Mining Software Repositories, New York, NY, USA, 2005.

There are actually 2 versions: one takes a Revision and one takes a string.

Regarding implementation, you can view the concrete implementation here: https://github.com/boalang/compiler/blob/master/src/java/boa/functions/BoaIntrinsics.java#L68

Short answer no, it does not implement those heuristics, it is just a simple regex.

Thanks for the quick response!

This may be an issue of PEBKAC, but I tried the version that uses Revision instead of string (string does work), but it doesn't work (from this example).

This gives me:

Error at lines 29-29, columns 13-28: no such function isfixingrevision([Revision])

v := visitor {

before rev: Revision ->

if (isfixingrevision(rev))

foreach (i: int; def(rev.files[i])) {

file := rev.files[i];

filenames[changeType(file)] << file.name;

}

};

  Maybe the version of boa that takes Revision is not deployed on the public facing service?

[Robert E Dyer]

That is true.  Each dataset has its own compiler version.  The SF dataset is older, and using an older compiler which apparently did not have that version of isfixingrevision().
