gem help cert does not show -d/--days

[djberg96]

gem -v => 2.6.8

The option to add -d/--days to gem cert was merged: #1719

But when I run gem help cert I see no reference to the new option. It does actually work in practice, though.

@djberg96 this feature is not in 2.6.8 but will be in 2.7

[bronzdoc]

said that... idk how are you using that flag in 2.6.8 🤔

[djberg96]

@bronzdoc Didn't complain when I used the options:

dberger:~ >gem -v
2.6.8

dberger:~ >gem cert -b djberg96@xxx.com -d 1000

Yeah it's weird, I just tested it, also I tested it passing the flags to rubygems 2.6.0 and still accepts the flags without crashing. This is something that has been there for a long time probably even before 2.6.0, so this seems to work in the current version but the functionality isn't there...

if you do:

pem = File.read("./gem-public_cert.pem")
cert = OpenSSL::X509::Certificate.new(pem)

and then inspect cert you will see not_before and not_after are a year apart still, even if you did something like gem cert -b djberg96@xxx.com -d 1000

@djberg96 I investigated it a little more and it seems that OptionParser will try to match a single letter flag to any existing flag, e.g -l will match '--list' in this case since there's no flag that explicitly defines the behavior of -d it will match to --debug which is a common option in rubygems.

@bronzdoc Ok, thanks for looking into that.
