[xmds-devel] XMDS2 fails with PyParsing 3.3.3

[Rafael L. <ra...@de...>]

Dear XMDS developers,

A bug report has recently been filed against the Debian package xmds2 [1]. It reports the failure of several unit tests during the building of the package. The full build log is available [2], although I do not know whether this URL is permanent.

I believe that the failures are caused by upgrading PyParsing to version 3.3.3. With version 3.3.2, the xmds2 Debian package builds correctly.

I detected two types of failure. One relates to the parsing of inline comments ("/* ...*/") failing, and the other relates to the "=>" construct not being treated correctly. The latter seems to be caused by line 170, inside the nonlocalDimensionAccessForComponents() function in the xpdeint/CodeParser.py file:

     tokenDict = dict(list(tokens.access[0].items()))

This code appears to depend on the internals of the ParseResults class, and is not yielding the correct result. Unfortunately, I do not have the necessary skills to fix the problem.

I hope you will find a fix for the problem.

Best,

Rafael Laboissière
