427500 - Upgrade the copy of MochiKit used in Mochitest, to v1.4.2

Status: RESOLVED WONTFIX

(Testing :: Mochitest, defect)

Description

[Jonathan Watt [:jwatt]]

I recently upstreamed a patch to make MochiKit play nicely with SVG. We still need to pull a more recent version to be able to use these improvements though.

Comment 1

[(not currently active) Ted Mielczarek]

I assume you mean "Update the copy of MochiKit used in Mochitest"?

Comment 2

[Jonathan Watt [:jwatt]]

Yes.

Comment 3

[Serge Gautherie (:sgautherie)]

Which version do you want to upgrade to?

{

NB: It looks like we might want to upstream patches to these 3 files from mozilla-central to (future) MochiKit v1.5...

[Serge Gautherie (:sgautherie)]

Attachment: (Dv1a) re-Apply Mozilla patches over bare MochiKit-1.4.2/tests/

Dv1, updated to pass on try servers:
*1 typo fixed in Makefile.in.
*3 updated tests:
 *test_MochiKit-JSAN.html was/is never run.
 *test_MochiKit-DragAndDrop.html was not run (at all) before.
 *test_MochiKit-Style.html fails some newly-added checks.

I don't know whether the 2 latest tests failures are bugs in MochiKit or "Gecko":
I'll file follow-up bugs, fwiw.

Comment 13

[Robert Sayre]

why do we want to upgrade it? shouldn't we add a new copy instead?

What would be the use for the obsoleted version?

Comment 15

[Mike Shaver (:shaver emeritus)]

We should have the old MochiKit in the test matrix somewhere, because it's still deployed on sites and we don't want to break it unawares.  For use in Mochitest I'm not sure that we need both, but if Mochitest is our implicit MochiKit coverage, we should make sure we replace it with explicit coverage of that version.

Comment 16

[Serge Gautherie (:sgautherie)]

(In reply to comment #15)

> We should have the old MochiKit in the test matrix somewhere,

MochiKit has 13 tagged versions from 0.50 to 1.4.2:
http://svn.mochikit.com/mochikit/tags/

Which version(s) do you want to explicitly test?
*1.4.2:
 This one, obviously, as we will use it in our own test harness.
*1.4 (or 1.4.1):
 1.4.2 should be enough.
*("pre-v1.4 == r1174" or) "pre-v1.4 == r1182":
 Even if we were/are using it, we shouldn't care (anymore) for such a dev rev.
*1.3.1:
 If you want to care for an older version, this should be the one.
*Any even older versions?

> because it's

You mean sites "in the wild, not Mozilla related", right?

> For use in Mochitest I'm not sure that we need both,

We obviously don't.

> but if Mochitest is our implicit MochiKit coverage,

I wasn't aware of this goal,

> we should make sure we replace it with explicit coverage of that version.

but that can make sense, and is trivial to do.

Ftr,

test_MochiKit-DOM-Safari.html, test_MochiKit-DragAndDrop.html and test_MochiKit-JSAN.html are not run by MochiKit index.html.

test_MochiKit-JSAN.html is actually broken,
but test_MochiKit-DOM-Safari.html passes as is.

test_MochiKit-DragAndDrop.html initially failed with
"not ok - test suite failure! message: MochiKit.DragAndDrop.Draggable is not a constructor fileName: http://localhost:8888/tests/MochiKit-1.4.2/tests/test_DragAndDrop.js lineNumber: 7 stack: [...]"
but the Error Console reported
"Error: uncaught exception: MochiKit.Visual depends on MochiKit.Position!"
and
"Error: uncaught exception: MochiKit.DragAndDrop depends on MochiKit.Position!"
so I added the missing script "include" to make the test pass.

And I added a workaround to test_MochiKit-Style.html: see comment 12...

Ping for reviews of Fv1 and Gv1.

Comment 21

[Rob Campbell [:rc] (:robcee)]

these are huge and will require considerable time to review and test. Time I don't have at the moment. I'll get back at this next week unless someone beats me to it.

serge, these try builds passed on all platforms? Can you point to the logs?

Comment 22

[Rob Campbell [:rc] (:robcee)]

pressed "commit" while still reading the timestamp on your comment #19. That was a month ago, so finding those logs could be difficult.

Comment 23

[Serge Gautherie (:sgautherie)]

(In reply to comment #21)
> these are huge and will require considerable time to review and test.

Fv1 is 555 kB but it's only importing files from MochiKit svn:
no code to review actually, just looking for an answer/confirmation to comment 16 question/list about versions ;-)

Gv1 is 31 kB but it's mostly makefiles and repeated same path fixes:
the "additional" changes to review are very few and easy (see comment 18 (and comment 12)) and touch tests only (not MochiKit code itself).

Fwiw, my plan is:
1- Land these. (and do the same for other versions if wanted.)
2- Rework the other patches.
3- Upstream whatever fixes which were not yet.

Comment 24

[Rob Campbell [:rc] (:robcee)]

I'm not going to just put a rubber stamp on these things without verifying for myself that it doesn't break our unittest suite. This means a full build and unittest run. I also expect there may be landing difficulties with this on our production unittest builders. It'll have to wait until I have time to review it properly.

Comment 19 was meant to cover this...
That said, I obviously see no problem in having you check for yourself.

Well, if tests passed on Try and would then fail on Production, then there would be something really wrong in the process...

Would it be enough if I re-submit these patches to Try?
Or do you plan on doing some different testing actions yourself?

Comment 26

Ping for review, anyone?

Comment 27

[Rob Campbell [:rc] (:robcee)]

Sorry I don't have time to review these behemoths right now. Also, landing significant changes to our test suites could be dangerous given the proximity to 1.9.2 release.

Patches F and G are: see comment 23.

Comment 31

[cmtalbert]

So, I ran the F and G patches through try server last night and these tests seemed to pass.  Here are the logs:
* Linux: http://tinderbox.mozilla.org/showlog.cgi?log=MozillaTry/1271118992.1271129436.509.gz
* Mac: http://tinderbox.mozilla.org/showlog.cgi?log=MozillaTry/1271118992.1271132262.8381.gz
* Windows: http://tinderbox.mozilla.org/showlog.cgi?log=MozillaTry/1271118991.1271132135.8036.gz

I also did some diff's between this and an unpatched build and I have some questions to be sure I understand what you're doing here, Serge.

It looks like you're just adding in the new Mochitest so that it becomes <objdir>/_tests/testing/mochitest/tests/MochiKit-1.4.2 and is included for testing in our grand pass of mochitests.  You're not changing the default MochiKit installation that the infrastructure uses.

And I should note that this does take down the "scary" factor of these two patches quite a bit as this really only adds another test suite to mochitest.  It doesn't actually affect the current mochitest harness infrastructure at all.  Is that what you were trying to get across in comment 23?

I might be block-headed here, but allow me to outline this as I see it:
* Patch F & G get us the updated mochikit code in the tree so that we can run it and run the MochiKit unit tests on that code.
* Patch A & B actually put the updated 1.4.2 code into the test harness and change the automation to use the updated code from that point forward.
* You want us to review F & G first, and then we'll work on changing the harness, right?

Is that all correct?

(My apologies if that was clear to everyone else).

Thanks. (This confirms comment 19 :-))

Correct: that's the comment 16 part.

I'm leaving out tests/index.html and tests/SimpleTest/*,
because we want to check their code and tests but inside our (modified) harness.

>  Is that what you were trying to get across in comment 23?

Exactly.

> * Patch F & G get us the updated mochikit code in the tree so that we can run
> it and run the MochiKit unit tests on that code.

Yes: at this point, the code is included for the only purpose of running the tests on it.

> * Patch A & B actually put the updated 1.4.2 code into the test harness and
> change the automation to use the updated code from that point forward.

Yes: the main point is I am/will splitting out the 2 currently-mixed purposes:
*Testing (bare) public MochiKit itself.
*Using (a tweaked version of) it to run our own mochitests.

> * You want us to review F & G first, and then we'll work on changing the
> harness, right?

Yes: I'll see what's left of A to E patches at that point.

I ran through the diffs between this and the 1.4 version we currently have in use on m-c. There are some things in here that will likely break some tests - mochiKit is capturing scroll events now and mousewheel events, and I pessimisticly believe that will cause test failures once we turn this on as the default MochiKit base for the harness.

That said, since this patch only adds the new MochiKit 1.4.2 version as a test suite inside mochitest/tests/MochiKit-1.4.2/MochiKit it is safe to take now and we can deal with the fallout of switching to 1.4.2 as the default later on.

r+ for landing as another test harness inside mochitest.

The original code in this case refers to this Makefile.in itself.  It does not refer to the MochiKit code (as I understand it).  So, the initial developer is you or your employer as the case may be.  

I know that the code that you're wrapping with the makefile is indeed MochiKit code, but the MPL is a per-file license and only refers to our current file, which is this makefile which is your code and not MochiKit's.

We have included their license in patch F, which I think is all we have to do here.

Now, if this is actually a makefile that mochiKit used in their codebase, then you should leave it as is, but I doubt that MochiKit uses our style of makefiles.

>+#

Likewise, the initial developer of this makefile is you, not Mr. Ippolito.

Apply those nits to the next two makefiles in the patch too, please.  I actually went and looked this up cause I wasn't sure.  It is covered under point 4 on this page: http://www.mozilla.org/MPL/license-policy.html

Do we know why this fails when it is not run standalone?  Is it just because that's how the MochiKit folks intended the test to run?  Or is something actually broken here?  If it's just how the mochiKit folks intended the test to run, then I'm ok with this change.  If something is broken, then let's file a follow-up bug.

This looks good.  I wonder if we shouldn't also include test_MochiKit-JSAN.html in that list too since it can't be run without the JSAN and since you note that it will be removed in mochikit 1.5 anyway.

My only nit is that all these files are still in this updated patch, so please take care not to add them when you go to check this in.
