Description (last modified by )
It seems that nothing really guarantees the existence of the directory SAGE_EXTCODE
($SAGE_ROOT/local/share/sage/ext
) apart from the installers of some packages.
When Sage is started when that directory doesn't exist:
[...lots of stuff...] /release/merger/sage-5.7.beta0/local/lib/python2.7/site-packages/sage/interfaces/all.py in <module>() 7 8 from expect import is_ExpectElement ----> 9 from gap import gap, gap_reset_workspace, gap_console, gap_version, set_gap_memory_pool_size, is_GapElement, Gap 10 from gap3 import gap3, gap3_console, gap3_version, Gap3 11 from genus2reduction import genus2reduction, Genus2reduction /release/merger/sage-5.7.beta0/local/lib/python2.7/site-packages/sage/interfaces/gap.py in <module>() 1457 # if the modification time of the gap link has changed (which signals 1458 # that gap has been somehow upgraded). -> 1459 if not os.path.exists(WORKSPACE) or os.path.getmtime(WORKSPACE) < os.path.getmtime(GAP_STAMP): 1460 #print "Automatically updating the cached Gap workspace:" 1461 #print WORKSPACE /release/merger/sage-5.7.beta0/local/lib/python/genericpath.py in getmtime(filename) 52 def getmtime(filename): 53 """Return the last modification time of a file, reported by os.stat().""" ---> 54 return os.stat(filename).st_mtime 55 56
This is a regression because conway_polynomials from #12205 runs Sage code at build time at a time when the existence of SAGE_EXTCODE
is not guaranteed.
The attached patch solves this problem in two ways:
- It only checks for and generates workspaces when actually starting GAP, not when Sage is started.
- Instead of using
SAGE_EXTCODE
(which doesn't really make sense), check the modification time of$SAGE_LOCAL/bin/gap
.
