Why doesn’t “puts Time.now.to_f” print the fractional part of the
current epoch second?
I’ve confirmed that it “is_a?” Float. And I’ve done it several times,
to be sure that it’s not falling on an exact second.
This is Cygwin Ruby 1.6.8, BTW. On Windows XP.

I think the digits are there, they just are not printing.

Thanks for the results, Jim. You’re right that the digits are there,
the subtraction above proves it. But why wouldn’t they print? They
are Floats. Float#to_s prints digits (e.g. the literal 1.5).
It is as if the results from Time.to_f are singleton objects whose
#to_s has been rewritten!
I wish there was a way to know if an object is a singleton or has
otherwise been structually modified.

I think the digits are there, they just are not printing.
I have searched the archives and posted this message three times
and have yet to get a response. I am trying to create a web page
that let’s a user upload a file.
OK, I felt sorry for you and looked in too it just now (but I
had already deleted your mail, so I high-jacked another one from
you, possibly upsetting people’s threading mail-clients, inserting
the contents of your original posting from the mailinglist archive).
I have worked through most of the issues, and can even get
a file on to my server, but it is embedded in a binary file
whose format is unknown.
Has anyone experience with this, or is there documentation on
how to extract the file data from what is sent to the server?
Below is an example of the file I get from webrick.
The original contents of the file v.rb is “This is a test.\n”
The spooky data is a boundary, which also is submitted via the
CONTENT_TYPE environment variable.
Test the following html-file (invalid, lacks head, body, and such):
with this ruby-snipet as the responding cgi action[1]:
#!/usr/bin/ruby -w
puts “Content-type: text/html\n\n”;
puts “–START–
\n”;
while line = gets()
puts line;
end
puts “
–STOP–
\n”;
ENV.each_pair { |e, v|
puts "#{e} = #{v}<br>\n";
Look especially at the value of CONTENT_TYPE. Is it not that boundary
that comes before and after the actual contents of the file you chose
to upload?

Thanks for that, Guy. I’ve confirmed it here. Silly me, I should
have tried that literal in the first place.
