[viff-devel] [issue62] Proper error message when no certificate present

[Thomas Pelle Jakobsen]

New submission from Thomas Pelle Jakobsen <mas at daimi.au.dk>:

Currently, if one forgets to generate certificates using the
generate-certificates.py script and then runs e.g. the millionaires.py
example 
with ssl this is what results:


C:\temp\viff-ff249565fa3a\apps>python millionaires.py player-3.ini
Seeding random generator with random seed 9235
Using SSL
Traceback (most recent call last):
  File "millionaires.py", line 150, in <module>
    pre_runtime = create_runtime(id, players, 1, options, Toft05Runtime)
  File "C:\Python25\Lib\site-packages\viff\runtime.py", line 1619, in
create_runtime
    ctx_factory = SSLContextFactory(id)
  File "C:\Python25\Lib\site-packages\viff\runtime.py", line 1607, in
__init__
    ctx.use_certificate_file('player-%d.cert' % id)
OpenSSL.SSL.Error: [('system library', 'fopen', 'No such file or
directory'), ('BIO routines', 'FILE_CTRL', 'system lib'), ('SSL
routines', 'SSL_CTX_use_certificate_file', 'system lib')]

What the user should see is instead something like this:

Runtime.Error: Couldn't find ssl certificates.
Hint: Run the generate-certificates.py first.
