Description
From http://groups.google.com/group/sage-support/browse_thread/thread/9aa4fa8cdb5d8b90:
After a lot of headaches over some mysterious behaviour in some scripts, I found the following: I have two files: test1.sage contains: attach test2.sage print "test1", 1/2 test2.sage contains: print "test2", 1/2 When I say on the command line of sage 3.3: attach test1.sage, the output is (correctly): sage: attach test1.sage test2 1/2 test1 1/2 But on sage 4.01, the output is: sage: attach test1.sage test2 0 test1 1/2 It looks as if on a file that is attached from another attached file, no preparsing takes place. If within this same session I touch test2.sage, it works fine.
This is only a problem in the IPython interpeter; when running from the command line, the files are recursively preparsed correctly.

This appears to be fixed, post-#7514. For example, with
> cat test1.sage attach test2.sage print "test1", [1..10] > cat test2.sage print "test2", [11..20]
I see
sage: attach test1.sage test2 [11, 12, 13, 14, 15, 16, 17, 18, 19, 20] test1 [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] sage: attached_files() ['test1.sage', 'test2.sage'] sage: # After 'touch test2.sage' test2 [11, 12, 13, 14, 15, 16, 17, 18, 19, 20] sage: # After 'touch test1.sage' test2 [11, 12, 13, 14, 15, 16, 17, 18, 19, 20] test1 [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
If I'm correct, should we close this ticket?

Just briefly looking around, perhaps there's a problem in
preparse_file()
insage.misc.preparser
: when attaching a .sage file, it does:In the example given in this ticket, it seems to just insert the lines of test2.sage without preparsing them.
