All known issues have been fixed, and all long doctests pass on sage.math (* -- see below), so there is a chance this could be sage-4.1.
The source tarball: http://sage.math.washington.edu/home/rlmill/release/sage-4.1.rc1.tar sage.math binary: http://sage.math.washington.edu/home/rlmill/release/sage-4.1.rc1-x86_64-Linux.tar.gz Upgrade URL: http://sage.math.washington.edu/home/rlmill/release/sage-4.1.rc1/ (Note - If you are upgrading from rc0, you need to force a rebuild of Singular) There were four fixes merged, one fixing an issue so that the PDF reference manual would build, one doctest issue with graph eigenvalues, a fix to MANIFEST.in, and the upgrade to Singular 3.1.0.4 (from 3.1.0.2) was reverted, as it fails to build on OS X. * -- There was witnessed the following Heisenbug: sage -t -long devel/sage-main/sage/graphs/graph_plot.py libpng error: Image width or height is zero in IHDR ********************************************************************** File "/space/rlm/sage-4.1.rc1/devel/sage-main/sage/graphs/ graph_plot.py", line 707: sage: D.show() Exception raised: Traceback (most recent call last): File "/space/rlm/sage-4.1.rc1/local/bin/ncadoctest.py", line 1231, in run_one_test self.run_one_example(test, example, filename, compileflags) File "/space/rlm/sage-4.1.rc1/local/bin/sagedoctest.py", line 38, in run_one_example OrigDocTestRunner.run_one_example(self, test, example, filename, compileflags) File "/space/rlm/sage-4.1.rc1/local/bin/ncadoctest.py", line 1172, in run_one_example compileflags, 1) in test.globs File "<doctest __main__.example_7[36]>", line 1, in <module> D.show()###line 707: sage: D.show() File "/space/rlm/sage-4.1.rc1/local/lib/python/site-packages/ sage/graphs/graph.py", line 6760, in show self.plot(**plot_kwds).show(**kwds) File "/space/rlm/sage-4.1.rc1/local/lib/python/site-packages/ sage/plot/plot.py", line 1292, in show hgridlinesstyle=hgridlinesstyle) File "/space/rlm/sage-4.1.rc1/local/lib/python/site-packages/ sage/plot/plot.py", line 1627, in save canvas.print_figure(filename, dpi=dpi) File "/space/rlm/sage-4.1.rc1/local/lib/python/site-packages/ matplotlib/backend_bases.py", line 1453, in print_figure **kwargs) File "/space/rlm/sage-4.1.rc1/local/lib/python/site-packages/ matplotlib/backends/backend_agg.py", line 334, in print_png filename_or_obj, self.figure.dpi) RuntimeError: Error building image ********************************************************************** This leads me to conclude that the age-old "Sage is trying to plot an edge vertically or horizontally without adjusting image bounds appropriately" bug, which I think I've fixed three different times in various places, just will not die. That said, I ran this test again ten times and it passed each time. I think it requires the spring layout to terminate with the edge at just the right angle to be triggered. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
