Numeric captcha '2*4 is?' to create new settings

[sergeych <sergeych@…>]

Captcha asks question only if name and email are both empty, otherwise is skipped.

The patch for trunk/trac and trunk/templates. Error reporting should be improved - don't know what style to use to report wrong answer.

Found a potential problem. I'm passig captcha answer between requests in the request handler instance var. I'm afrais thi is not good so I'll move it to the req.session very soon. I'm sorry.

BTW askimet just rejected my comments again :)

I think that it's time to add optional password to protect the account?

Sergey, this can be entirely implemented as an IRequestFilter. I have a basic implementation that I'll attach for you to test.

Captcha plugin implemented with the IRequestFilter interface

Give that a try. The user will be challenged with a Captcha the first time they POST a form. There is some dodgy hackery to achieve this, so it may not work in all cases. Seems to work with Wiki and ticket updates though.

The default captcha implementation is pretty much your one. An image captcha can be enabled by installing PIL and updating TracIni with:

[captcha]
captcha = ImageCaptcha

There's also a http://captcha.net implementation, but I haven't received the authentication tokens yet and so haven't been able to test it.

Num captcha integrated in Settings

[sergeych <sergeych@…>]

Well I suppose we use the simpler approach:

• if the user has not set hist nick or email, he or she (or it) may not post anything, so one need to set it up in one's settings. AFAIK it is already done?

• in the settnigs screen when person for the first time enters one's nick and/or password, ones is asked for captcha.

• as long as the user has name and or email fields not blank the captcha on settings change is inactive.

Well the numcaptcha2.patch should work as described

I've uploaded the plugin to TracHacks.

This is not a test system; please do not close tickets for no reason.
