Description

There is no longer any good reason for nsIX509Cert2 and ...3 to be separate interfaces from nsIX509Cert, now that we don't freeze interfaces.

add'l patch: remove ignoreOcsp argument from GetUsagesArray/GetUsagesString

While developing the patch above I noticed that all callers of GetUsagesArray and GetUsagesString pass FALSE to their ignoreOcsp argument, and the async version of GetUsagesArray doesn't even *have* that argument; so this additional patch removes it.  It is a separate patch for approval's sake -- maybe there's a good reason to do the merge but keep this argument around -- but, on the theory that it would be landed together with the other one, does *not* bump the IID on nsIX509Cert, since we just did that.

I checked comm-central for additional uses of ignoreOcsp but did not find any.

NS_Free, please. Although I doubt this is the right allocator for NSS. http://mxr.mozilla.org/mozilla/source/security/nss/lib/certdb/cert.h#804 says to use PORT_Free.

Uses PORT_Free instead of nsMemory::Free as requested; also fixes a silly mistake caught in the process of writing an automated test for bug 234856.

Shouldn't the Component be "Security: PSM"? This mostly touches stuff under security/manager/... (and nothing under netwerk/, actually).

Security:PSM has a component description that makes it sound like it's for some weird piece of NSS that Firefox doesn't actually use.  I've since been told it is the place for this sort of bug, yeah.

What happens when code written with the ignoreOcsp argument calls the new function? Hopefully xpconnect throws an exception? or does it try to interpret the args and come up with something mysterious?

Looks like a few addons use this and are going to break. Will they notice what's wrong? Is it at all possible for them to write their addon to work with both the new form and old form (not everyone will upgrade immediately)? Check properties on the cert they get before they QI to Cert2 or Cert3 forms and see if it has the merged methods or not? In JS add-on code no one is using the IID so changing it doesn't help them (but helps C++ callers).
These methods are used (with ignoreOcsp always false) by the "GMail S/MIME", "Key Manager", and "XML Digital Signature Procesing Tool" addons.

biesi is the wrong reviewer for PSM, adding a review request.

I'm ok with the merging in theory, will wait for kai's r+ before looking in depth.

There are no in-tree JS uses of these functions, and I'm not sure how to call an IDL-declared function with non-[retval] out parameters from JS, so I don't know how to do an experiment here.

> Looks like a few addons use this and are going to break.

How did you search add-on source code?

I was able to do an experiment for the merge-CertN patch (not the ignoreOcsp patch) by enhancing the test case for bug 234856; both Cert2 and Cert3 add a read-only attribute that's easy to look at.  I was hoping that XPConnect objects were duck typed from JS's perspective, so if you had an object with nominal type nsIX509Cert you could call Cert2/Cert3 methods on it without bothering to call QueryInterface first, but it is not so.  Pre-these patches, if you don't do

    cert.QueryInterface(Ci.nsIX509Cert3);

then Cert2/Cert3 properties are undefined.  But post-these patches, that QI call throws an exception.  If you want to write code that works with both you have to do

    if("nsIX509Cert3" in Ci)
      cert.QueryInterface(Ci.nsIX509Cert3);

which naturally no one will have bothered to do yet.  I'd be okay with adding back stub nsIX509Cert2 and Cert3 interfaces that don't do anything but make those QI calls succeed.
Zach, there are other incompatible changes to these interfaces I want to make--most notably, deprecating and/or removing the methods that verify certificate chains, because certificate chain validation must not happen on the main thread, because it blocks the calling thread too long.

As all these changes will affect addon compatibility, I think we should do them all at the same addon-breaking time. I also want to give advance notice to addon developers about the breaking changes.

That would be fine with me.  Do you have a timeframe?

add'l patch: remove ignoreOcsp argument from GetUsagesArray/GetUsagesString

This interface change will break the "GMail S/MIME" and "Key Manager" addons at least, of the AMO addons I was able to grep. Those authors need to be notified if this goes through.

merge cert interfaces, revised

In addition to "Key Manager", nsIX509Cert3 is used by "Cert Viewer Plus" and "Skip Cert Error" (a successor to MitM Me).

nsIX509Cert2 is used by Cipherfox, Cert Viewer Plus, XML Digital Signature Procesing Tool, and Key Manager.

I don't know how much of AMO my corpus contains, I may be missing a significant number of addons. I also would not have found use of these interfaces from binary components in AMO-hosted addons. I have no visibility whatsoever into non-AMO-hosted addons.

If bsmith is planning breaking changes to these interfaces we should definitely combine them. Removing sr request until after Kai has reviewed.

Do you think it would be better to preserve the argument for interface compatibility's sake, but have it throw NS_ERROR_NOT_IMPLEMENTED if it were ever passed as 'true'?  I could do that.

What do you think of preserving them as empty interfaces so that QueryInterface succeeds?  Inheriting, so one may still call nsIX509Cert methods on an nsIX509Cert3*.  Would that reduce the compat burden?

merge cert interfaces, revised

I apologize, but I don't have time for nice-to-have cleanup patches.

Furthermore I'm worried you will unnecessarily break add-ons that make use of this separation. In order to keep things compatible, you should consider tohave dummy derived interfaces, that are empty, allowing compatibility with add-ons because using the old names will still work.

I give you module owner approval, but please make very sure this doesn't cause any trouble, when in doubt, I'd prefer wontfix.

I'll generate a new version that preserves stub interfaces for compatibility.  This probably won't happen before September.  Clearing review requests.

Zack, are you still interested in working on this? This is something I would like to see happen.

I would also like to see this happen, but I don't know when I'm going to have time to do Firefox work again.  The research is being very time consuming right now.

Ok - no worries. I'll go ahead and unassign you in case anyone else is interested.

For anyone looking to do this, we should also merge nsIX509CertDB2 into nsIX509CertDB at the same time.

Review of attachment 8446332 [details] [diff] [review]:
-----------------------------------------------------------------

Well done so far. There are a few issues:
- Any interface that changes needs to have its uuid updated (see comment below)
- Watch out for trailing whitespace on lines touched by this patch or too much vertical space. Generally multiple blank lines in a row are unnecessary.
- Make sure &/* indicators are next to the type name: 'const nsAString& foo' on lines touched by this patch
- Let's not make changes unrelated to merging these interfaces (e.g. the style nits in nsNSSCertificateDB.cpp)

Upon thinking about this more, we should just go ahead and remove the unneeded interfaces. The changes required of addons that use these interfaces are completely mechanical and won't be too much of a hardship. It would be necessary to send an email to the appropriate newsgroups when we're ready to land this, though.
