I haven't done a patch for textareas yet; I wanted to get this up for a first look. Known problems (which keep this from being reviewable): (1) ###!!! ASSERTION: Class name and proto chain interface name mismatch!: 'nsCRT::strcmp(CutPrefix(name), mData->mName) == 0', file m:/webforms2/mozilla/dom/src/base/nsDOMClassInfo.cpp, line 3380 name == "nsIDOMWF2ValidityState", mData->mName == "DOMWF2ValidityState". (2) http://webforms2.testsuite.org/controls/common-attributes/required/001.htm DOM Inspector shows for inputs 2 and 3 that (input).validity.valid is indeed true (which is expected), but the CSS pseudoclass doesn't apply, apparently. I show a similar result for http://webforms2.testsuite.org/controls/common-attributes/required/003.xht . Other notes: * http://webforms2.testsuite.org/controls/common-attributes/required/002.htm The required attribute uses NS_IMPL_BOOL_ATTR, which has never before checked the actual value of the attribute. I believe that by the current draft of the spec, the test is actually invalid. HTML does not require the attribute value be "required", and technically speaking, neither does the current draft (in a normative way). XHTML does require it, but we've never gone out of our way to check that (and we should start - it should be easy to adjust the macro itself to check for a XHTML document type). There's a bug on file somewhere about this. That said, I'd have no objection going forward to writing a NS_IMPL_BOOL_ATTR_MATCH attribute for required and other new WF2 attributes, and forcing the value check.

Hixie's corrected me by e-mail: the value of the attribute doesn't matter to the implementation. We fail 002.htm only because of an issue with the CSS pseudoclasses.

sicking says the pseudoclass selectors issue need not block this patch. The other two problems I knew about - the assertion and events not being dispatched - I have fixed. I've also implemented support for textareas.

I added the following lines to nsDOMWF2ValidityState.h: #define NS_VALIDITYSTATE_CID \ { /* 215793da-b1b2-4784-9f2d-f6368a90302c */ \ 0x215793da, 0xb1b2, 0x4784, \ {0x9f, 0x2d, 0xf6, 0x36, 0x8a, 0x90, 0x30, 0x2c} } #define NS_VALIDITYSTATE_CONTRACTID \ "@mozilla.org/webforms2-validity-state;1" This patch does corresponding work for nsLayoutModule.cpp. It turns out I need this for exposing the validity state code to non-C++ code (in particular, XBL-based WF2 controls, such as <html:output/>).

Comment on attachment 230689 [details] [diff] [review] patch, v1 In general there are too many new interfaces. I would really like to get rid of some if at all possible. It seems like you should be able to add properties to existing 'NS' interfaces (like nsIDOMNSHTMLInputElement) rather than adding new interfaces. Validation may still need its own interface though. Or you could maybe add methods to nsIFormControl. If we really do need to keep the nsIDOMWF2InputElement it needs to have a different name since it's implemented by textareas. >Index: content/html/content/src/nsHTMLFormElement.cpp >+nsHTMLFormElement::CheckValidity(PRBool *_retval) ... >+ if (*_retval && !validity) { >+ *_retval = PR_FALSE; No need to check if _retval has already been set. That checks costs you about as many cycles as setting too often will. Also, prefix the _retval argument with 'a' (like aResult). >Index: content/html/content/src/nsHTMLInputElement.cpp >+nsHTMLInputElement::GetWillValidate(PRBool *aWillValidate) >+{ >+ *aWillValidate = PR_FALSE; >+ >+ if (!mForm) >+ return NS_OK; >+ >+ /* XXX ajvincent No ancestor of this node may be a repetition element or >+ a datalist element, but those haven't been implemented yet. >+ */ >+ >+ if (!HasAttr(kNameSpaceID_None, nsHTMLAtoms::name)) >+ return NS_OK; >+ >+ if (HasAttr(kNameSpaceID_None, nsHTMLAtoms::disabled)) >+ return NS_OK; >+ >+ if (mType == NS_FORM_INPUT_RESET || mType == NS_FORM_INPUT_BUTTON) >+ return NS_OK; >+ Combine these to a single if-statement. You could even do *aWillValidate = mForm && HasAttr(name) && !HasAttr(disabled) && !(mType == NS_FORM_INPUT_RESET || mType == NS_FORM_INPUT_BUTTON) There's no readonly check. You should test for HIDDEN along with the other types. >+nsHTMLInputElement::GetValidity(nsIDOMWF2ValidityState * *aValidity) >+{ >+ NS_ENSURE_ARG_POINTER(aValidity); >+ >+ nsresult rv = NS_OK; >+ PRBool valid; >+ >+ if (!mValidity) >+ rv = CheckValidity(&valid); >+ NS_ENSURE_SUCCESS(rv, rv); >+ >+ /* XXX ajvincent Yes, I know there's a build warning from not using valid. >+ By calling on CheckValidity, we initialize the validity state object, >+ but also dispatch the invalid event if we're invalid. >+ >+ Suggestions would be welcome. >+ */ I don't think you want to call CheckValidity since that might fire an event, and I can't find anything in the spec saying that getting .validity should do that. If however that is the correct behaviour, just declare |valid| inside the if-statement to get rid of the warning. The solution here is probably to let CheckValidity call GetValidity rather than the other way around. And only test rv when you're actually setting it, i.e. inside the if-statement. >+NS_IMETHODIMP >+nsHTMLInputElement::CheckValidity(PRBool *_retval) >+{ >+ if (!mValidity) >+ mValidity = new nsDOMWF2ValidityState(); >+ if (!mValidity) >+ return NS_ERROR_OUT_OF_MEMORY; Put the second if-statement inside the first.

That doesn't seem to update the validitystate as needed? What you instead should do is to make the validitystate query the element inside validitystate::GetValueMissing. Same thing applies to all other validiystate bits, so i'll review the rest of this function when there's a new patch. >Index: content/html/content/src/nsHTMLTextAreaElement.cpp The comments to nsHTMLInputElement also applies to this file.

(In reply to comment #11) > Validation may still need its own interface though. Or you could maybe add > methods to nsIFormControl. The ValidityState interface is clearly defined in WF2, so I must implement it. I'll therefore stick with nsDOMWF2ValidityState. That said, I realized an edge case on the radio/checkbox valueMissing issue where I must anticipate form controls with the same name but not radio/checkbox types: <input type="radio" name="foo" required="required"/> <input type="text" name="foo" value="Hello World"/><!-- stupid authors --> <select name="foo"/><!-- equally stupid authors --> Since I now (after fixing review comments) implement GetValidity on nsIDOMNSHTMLInputElement and nsIDOMHTMLTextAreaElement, I'll want to try getting a validity state for other form control types as well. I'm thinking nsIDOMWF2ValidityState GetValidityState(); on nsIFormControl. The caller of GetValidityState() will have to do the OOM check. What do you think? > There's no readonly check.

I will not seek reviews for this patch. I had a bad feeling that I was letting a performance loophole slip by in my code today, and unfortunately I was right. Thanks to bz for suggesting this testcase, although he suggested sets of 100, 1,000 and 10,000 radio inputs. The time spent on 100 and 1,000 radio inputs shows this is unnecessary (unless you want to wait 200+ minutes). The problem is this: <form action="javascript:void()"> <input type="radio" name="foo" required="required"> <input type="radio" name="foo" required="required"> </form> In this form, each radio input has to check all the others. So it's a squared increase in processing time just for validity checking. 10 times as many radio inputs means 100 times as long in processing. Unacceptable. Suggestions? I'm thinking of a cache of the valid controls at the form level, started when a checkValidity() operation (either form or input) begins, and stopped when the same operation ends. Unless someone changes an input value during an invalid event, this should suffice.

It holds all states of and relations between instance nodes. Though I don't know much about wf2 and I can't say how xforms mdg will fit for wf.

The form has a name-to-list hashtable, no? You could keep, for each list, also a count of how many items in it are valid or whatever. That would be O(1) to update on mutations (increment or decrement a counter) and O(1) (well, O(log N) if hashtable collisions are bad) to check. But maybe I'm misunderstanding the problem you're trying to solve.
My question is, how long did it take for 100 radios and for a 1000 radios? How long did it take before the patch?

Comment 23•18 years ago

The question isn't entirely relevant at this stage; with this patch, validity checking on the required attribute is not yet tied into form processing at any point. I was saving that for another bug yet to be filed. So I can't test a "before" case. I am now beginning to regret my optimism of comment 0... :) sicking asked me how long it took to submit the form, and how long it took to do the checkValidity test. Test results on calling form.checkValidity: 15 milliseconds elapsed (test 1, form form_1). 16 milliseconds elapsed (test 2, form form_1). 15 milliseconds elapsed (test 3, form form_1). 15 milliseconds elapsed (test 4, form form_1). 32 milliseconds elapsed (test 5, form form_1). 15 milliseconds elapsed (test 6, form form_1). 16 milliseconds elapsed (test 7, form form_1). 16 milliseconds elapsed (test 8, form form_1). 15 milliseconds elapsed (test 9, form form_1). 16 milliseconds elapsed (test 10, form form_1). 1079 milliseconds elapsed (test 1, form form_2). 1078 milliseconds elapsed (test 2, form form_2). 1078 milliseconds elapsed (test 3, form form_2). 1078 milliseconds elapsed (test 4, form form_2). 1078 milliseconds elapsed (test 5, form form_2). 1094 milliseconds elapsed (test 6, form form_2). 1094 milliseconds elapsed (test 7, form form_2). 1078 milliseconds elapsed (test 8, form form_2). 1078 milliseconds elapsed (test 9, form form_2). 1079 milliseconds elapsed (test 10, form form_2). 142672 milliseconds elapsed (test 1, form form_3). 182438 milliseconds elapsed (test 2, form form_3). 188219 milliseconds elapsed (test 3, form form_3). 183797 milliseconds elapsed (test 4, form form_3). 180031 milliseconds elapsed (test 5, form form_3). 180219 milliseconds elapsed (test 6, form form_3). 179375 milliseconds elapsed (test 7, form form_3). 178984 milliseconds elapsed (test 8, form form_3). 178562 milliseconds elapsed (test 9, form form_3). 180203 milliseconds elapsed (test 10, form form_3). On average, it takes three minutes to check validity on the form with 10,000 identical radio inputs. It takes maybe a second to submit the form...

FWIW these are the results when running the testcase in Opera 9.01 on Linux on a three years old AMD Athlon 2500+ 1800 MHz: 25 milliseconds elapsed (test 1, form form_1). 103 milliseconds elapsed (test 2, form form_1). 40 milliseconds elapsed (test 3, form form_1). 10 milliseconds elapsed (test 4, form form_1). 11 milliseconds elapsed (test 5, form form_1). 11 milliseconds elapsed (test 6, form form_1). 14 milliseconds elapsed (test 7, form form_1). 11 milliseconds elapsed (test 8, form form_1). 10 milliseconds elapsed (test 9, form form_1). 11 milliseconds elapsed (test 10, form form_1). 42 milliseconds elapsed (test 1, form form_2). 38 milliseconds elapsed (test 2, form form_2). 53 milliseconds elapsed (test 3, form form_2). 36 milliseconds elapsed (test 4, form form_2). 37 milliseconds elapsed (test 5, form form_2). 39 milliseconds elapsed (test 6, form form_2). 82 milliseconds elapsed (test 7, form form_2). 37 milliseconds elapsed (test 8, form form_2). 44 milliseconds elapsed (test 9, form form_2). 59 milliseconds elapsed (test 10, form form_2). AFAICS Opera fully supports the "required" attribute.

Well, with bz's help, I tackled that perf problem. Radio and checkbox validity checking now happens in well under a second, even with ten thousand identically named controls. A couple observations: (1) I'm not really pleased with nsDOMWF2ValidityState::GetValueMissing at this time. It's repeating a lot more code than I feel comfortable with. I could optimize this by adding more methods to nsIFormControl, but the question is, which ones? (2) The perf testcases here uncheck all the inputs before starting the timer and validation. An interesting side effect is that GetValueMissing operates measurably faster when at least one control is checked than when none are checked, in both the radio and checkbox cases. I don't know why.

Why do you need a validity state object to return a boolean? <WeirdAl> the validity checking happens in the validity state object. are you suggesting it shouldn't? <bz> yes I'm suggesting it should happen in a non-COM function called by the state object and by nsHTMLInputElement::CheckValidity So that the latter doesn't have to create the former And in particular so form submission doesn't have to create all those nasty objects in the 99.999% case of the form needing no validation whatsoever I should note that then you could avoid the COM form of GetRequired too, maybe * bz mutters about a non-COM version of GetWillValidate too ... <bz> Or put some of it on nsIFormControl For example, + nsCOMPtr<nsIDOMNSHTMLTextAreaElement> input = do_QueryInterface(mOwnerElement); + NS_ASSERTION(input, "No html:textarea element?"); + + PRBool required; + nsresult rv = input->GetRequired(&required); That should be a method on nsIFormControl returning a boolean <WeirdAl> yeah, I thought a fair bit could go on nsIFormControl <biesi> bz, or a static method on this validity state class <bz> or what biesi said that last might be best, in fact. <WeirdAl> whoa, wait a sec... nsIFoo.h can have methods that don't return nsresult? <bz> yes

Drive by review comments, I'm of course not an official reviewer. NS_IMETHODIMP +nsHTMLFormElement::AddCheckboxCheck(nsAString& aName) +{ + PRUint32 count = GetCheckedCount(aName); + + count++; + PRBool valueSet = mCheckedBoxes.Put(aName, count); + return valueSet ?

NS_OK : NS_ERROR_OUT_OF_MEMORY; +} It's unfortunate that you have to do two lookups to increment or decrement a value. But looking at the nsDataHashTable/nsBaseHashTable interfaces there doesn't seem to be a way to get the entry. I'm not sure how performance sensitive this code is, but you might want to avoid the virtual call for GetCheckedCount. You could inline the code, or make a helper function(or hope nsIForm gets removed). I don't think mCheckedBoxes.Put can fail when decrementing a count, as there shouldn't be any allocation going on. + nsCOMPtr<nsIFormControl> control; + + PRUint32 len = sortedControls.Length(); + for (PRUint32 i = 0; i < len; ++i) { + control = sortedControls[i]; Do you need the extra reference to the form control? Hmmm, maybe you do because the invalid event can be fired from within the loop.
Comment on attachment 240733 [details] [diff] [review] patch, v3 The whole AddCheckboxCheck/RemoveCheckboxCheck thing doesn't work. If a checkbox is moved from one form to another things stop working. Also it wastes a lot of memory. I can think of two solutions: Either do what bz suggested in comment 21 and store the count of checked checkboxes for a given name in the same hash that we currently use to map name->list-of-controls. You would basically have to adjust the AddCheckboxCheck/RemoveCheckboxCheck functions to use that hash, and make sure to also update the hash when checkboxes are moved in and out of a form. You would also have to deal with controls changing into and from being checkboxes. Alternatively, you could let nsHTMLFormElement::CheckValidity create a hash on the stack and pass that has into the calls to the individual form controls when asking if they are valid or not. A checkbox would look up the result in that hash and return the result if it's already in there. If it's not in the hash the checkbox would ask the form for a list of all controls with the same name and walk that list to see if there are any checked checkboxes and then store the result in the hash before returning it. What's the purpose of having both IsValid() and CheckValidity() on nsIFormControl? DispatchInvalidEvent seems like it belongs in nsContentUtils rather than nsIFormControl. >Index: content/html/content/public/nsDOMWF2ValidityState.h >+class nsDOMWF2ValidityState : public nsIDOMWF2ValidityState >+{ >+ public: >+ NS_DECL_ISUPPORTS >+ NS_DECL_NSIDOMWF2VALIDITYSTATE >+ >+ nsDOMWF2ValidityState(nsIFormControl * aOwnerElement); >+ >+ virtual ~nsDOMWF2ValidityState(); >+ >+ private: >+ PRBool mValueMissing; What is the purpose of this member? >+ nsIFormControl* mOwnerElement; This can become dangling if the element is destroyed before the validitystate is. >+ protected: >+ /* additional members */ Why this comment? >+#define NS_VALIDITYSTATE_CID \ >+ { /* 215793da-b1b2-4784-9f2d-f6368a90302c */ \ >+ 0x215793da, 0xb1b2, 0x4784, \ >+ {0x9f, 0x2d, 0xf6, 0x36, 0x8a, 0x90, 0x30, 0x2c} } >+#define NS_VALIDITYSTATE_CONTRACTID \ >+"@mozilla.org/webforms2-validity-state;1" No need for this.

Btw, I would recommend the second option since I think that'll be simpler than keeping track of all the mutations that can affect the set of currently checked checkboxes. Though the first solution does deal better with checkboxes being checked and unchecked during the validation process. Not sure what the expected behavior is there. Maybe you should ask Hixie.

sicking: can you clearly state what the precise question is for Hixie to answer from comment 32? Also, I added the "helpwanted" keyword because I have no idea how to implement the second proposed solution in comment 31 (third paragraph).

I'm starting to think about picking up work on this again (though if anyone else has free cycles and wants to work on it, be my guest). I'm wondering if I should merge in the patch from bug 345624 - the two patches have to land together.

Alex, when you do get back to this, please include the accessibility part. On the element, STATE_REQUIRED needs to be set whenever this attribute is present, similar to what we do for WAI-ARIA. Let me know if you need any help with this!

By the way, this patch has a small difference from the specifications: when the input element is in file, checkbox or radio state, it is checking if the element is mutable and for the radio state, it is checking if another radio button is checked _and_ mutable. I've reported this to the working group: http://www.w3.org/Bugs/Public/show_bug.cgi?id=9505 If this is not accepted, it will be quite easy to remove it.

The radio button test results: 60 milliseconds elapsed (test 1, form form_1). 31 milliseconds elapsed (test 2, form form_1). 31 milliseconds elapsed (test 3, form form_1). 29 milliseconds elapsed (test 4, form form_1). 39 milliseconds elapsed (test 5, form form_1). 30 milliseconds elapsed (test 6, form form_1). 31 milliseconds elapsed (test 7, form form_1). 29 milliseconds elapsed (test 8, form form_1). 31 milliseconds elapsed (test 9, form form_1). 39 milliseconds elapsed (test 10, form form_1). 423 milliseconds elapsed (test 1, form form_2). 362 milliseconds elapsed (test 2, form form_2). 303 milliseconds elapsed (test 3, form form_2). 300 milliseconds elapsed (test 4, form form_2). 313 milliseconds elapsed (test 5, form form_2). 301 milliseconds elapsed (test 6, form form_2). 297 milliseconds elapsed (test 7, form form_2). 298 milliseconds elapsed (test 8, form form_2). 298 milliseconds elapsed (test 9, form form_2). 388 milliseconds elapsed (test 10, form form_2). Test completed. I had to change the test because checkValidity() is not implemented in the form at the moment so that is the result when calling checkValidity() for each form elements. I don't think the checkbox performance test is needed because AFAICT, a required checkbox means the checkbox has to be checked. And creating 10'000 checkboxs on load is just killing my firefox. The performance test are linear, so I suppose it's okay. Except if there is some issue related to form checking I'm missing but in this case, it will have to be fixed will implementing the form validation.

Here's what I'm thinking: PRBool nsHTMLInputElement::DoesReadOnlyApply() const { switch (mType) { case NS_FORM_INPUT_HIDDEN: case NS_FORM_INPUT_BUTTON: case NS_FORM_INPUT_IMAGE: case NS_FORM_INPUT_RESET: case NS_FORM_INPUT_SUBMIT: case NS_FORM_INPUT_RADIO: case NS_FORM_INPUT_FILE: case NS_FORM_INPUT_CHECKBOX: return PR_FALSE; #ifdef DEBUG case NS_FORM_INPUT_TEXT: // All other known input types break; default: NS_NOTYETIMPLEMENTED("Unexpected input type in DoesReadOnlyApply"); #endif } // switch return PR_TRUE; } I know this isn't the code style used in content code normally. What I'm thinking is, when we add new input types, the assertion will force us to explicitly recognize them in functions like DoesReadOnlyApply or DoesRequiredApply. Also, when --disable-debug, this results in logic identical to your form above. What do you think about this, smaug, sicking? volkmar: Don't feel compelled to do this. This is my opinion only, and might be overkill.

In my opinion, that's fine. Quite verbose but reasonable. In general, nsHTMLInputElement should be improved to have a better management of types. At the moment, it's really messy and it is going to be worst with all the new types coming with HTML5.

|GetValueModeType|, |DoesReadOnlyApply| and |DoesRequiredApply| are now future-proof as suggested by Alex in comment 52. For the addref issue, I think |nsDocument::GetCurrentRadioButtion| is called so it does an addref. I don't get what you meant by "Grammar nit: the first two are run-on sentences." For the messages, I did not changed them because they are more or less the same IMO. As I'm not a native english speaker, I can understand I do not feel the difference so if anyone around confirm that the proposed sentences are better, I will change them. All other points have been fixed in this updated patch.

I think the comment let the reader know what means "mutable" and if he/she wants to know _when_ the element is mutable, he/she has to read the code.
Comment 72•14 years ago

For what it's worth, I was going to comment objecting to such a terse, undescriptive name, maybe suggesting IsReadonlyOrDisabled, but then I looked at the patch/spec and saw it used that precise term. It's unfortunate the term's so vague, but as long as it's what the spec uses, and as long as the comment links directly to the term's definition, I tend to think IsMutable is the right choice and that the comment is as good as it can be.

I did object to it, and I agree with Jonas. See comment 54. As for the comment being outdated: Sorry, I don't buy that as a major problem. For the spec being vague, ping Hixie. That's our job as implementers of the spec, to point out deficiencies in it. I do think leaving a link to the specification in the comment is a good idea.

:required will not solve their problems. This red borders is the default style for invalid elements. This can be overridden with: :invalid { -moz-box-shadow: none; box-shadow: none; }

We need a default style for invalid elements because form submission will be blocked when invalid (that's the plan for beta6). See bug 561636 for more information.

This bug only seems to have covered implementing @required for <input> elements - but per spec it also applies to <select>. Is there another bug on file for that?

That was a spec change several weeks after this bug was fixed, for what it's worth.
