[Vm-dev] Stalled travis_tests in linux32x86

Mon Dec 4 20:58:16 UTC 2017

Hi Fabio,
no, I opened the test image --headfull and it is blocked in tests:

MCMockPackageInfo(PackageInfo) changeRecordForOverriddenMethod:

with parameter: a MethodReference MCMethodDefinitionTest >> #override

This is invoked from MCMethodDefinition>>tearDown.

It is blocked in this infinite loop:

        [file position < (position-1)]  "then pick it up from the front"
            whileTrue: [chunk := file nextChunk].

here file position is 0, and inst. var. readLimit is 0 too...
So nextChunk invariably return '' and the position does not advance.

Why is readLimit 0???
The file is TravisCI.changes and I can open and read it normally in the
FileList.
The problem comes from SourceFiles which already has an incorrect readLimit
set to zero (image attached)

It remains to discover how this ever happened, and why only in linux...
