Description Hixie (not reading bugmail) 1999-03-17 16:31:37 PST
ua.css contains many pseudos and properties which are presumably mozilla
extensions used to implement features that the specs currently do not specify.

These should all be marked, preferably by prefixing them with "-moz-", as has
been done in some cases. Not doing so runs the risk of a clash with future

Current cases of unmarked mozilla-native pseudos in ua.css are:

opacity should also be -moz-opacity. Closing bug 39168 as DUP.

David, Ian: we want this bug report to be a complete list of *all* mozilla CSS 
properties and pseudo classes that are extensions and should have the -moz- 
prefix. This bug was opened 14 months ago, and I note that opacity (bug 39168) 
is not on the list below. Could one of you please review our currently supported  
CSS properties and pseudo classes and make sure this list is 100% complete and 
up to date? We need to do that step in order to assess the feasibility and 
scheduling impact of making the change at this point.

pierre: It looks like XUL and our app UI may use some of these features. (e.g. 
I'm thinking that these property names may be hardcoded into our XUL UI files 
numerous places.) Am I correct? If so, is there a way we can gracefully make the 
changeover without disrupting others? For example: could we do something like:

step 1: add support for the -moz- names (leaving the old names also supported 
step 2: do some kind of global search and replace on the codebase to change all 
instances of the old property names to the new ones (since we probably don't 
have the luxury of freezing the tree, doing a mass Perl batch operation, and 
then reopening it, this might need to be done pieces at a time)
step 3: dropping support for the old names once we're sure the new ones are 
working and all usage instances within our code are out

Since I don't know how the code is internally set up, my specific suggestions 
for approach and process might be way off base, but is there some way we could 
achieve the general goal of fixing this without breaking the world? ;->

Marking helpwanted,css1,css3. It would be great if someone would volunteer to 
take this on!
Comment 7 ekrock's old account (dead) 2000-05-28 13:03:34 PDT
Copying in relevant comments from discussion in 39168. Adding jst and hyatt to 
cc: for jst to track DOM dependencies on this change and for hyatt to assess 
whether XUL has any dependencies on this change.

------- Additional Comments From Eric Krock -------

opacity is an under-development property in a  CSS3 draft, but it's not finished 
yet. If we have our own opacity in FCS,  developers write to it, and the final 
CSS3 draft specifies that opacity works in  a different way than our initial 
implementation, we'll be forced at that point  to (1) conform to CSS3 spec at 
the expense of breaking backward compatibility  and existing content, or (2) not 
conform to the CSS3 spec.

------- Additional Comments From Ian Hickson 2000-05-15 02:32 -------

I would go even further and suggest we just _rename_ our "opacity" property  to 
"-moz-opacity". Imagine if CSS3 does indeed introduce this property, but defines 
it totally differently to us (worse case scenario, for example: 100%  means 
totally transparent, and 0% means totally opaque). Now anyone  using "opacity" 
in the standards compliant way will find their documents look great in the next 
version of Mozilla, but DISAPPEAR in this version! Oops. 

------- Additional Comments From Johnny Stenback 2000-05-27 10:57 -------

There's more to this than just renaming this property in the style system, the 
DOM CSS OM also has knowledge about the supported properties in the interface 
CSS2Properties, and opacity is in there (in our interface, not in the DOM spec). 
Should we either remove opacity from our DOM interface, or should we leave it in 
and add -moz-opacity? Either way is easy to do, just let me know what you think.

*** Bug 39168 has been marked as a duplicate of this bug. ***
Comment 9 Hixie (not reading bugmail) 2000-06-16 08:58:47 PDT
Note that we know that a mass search-and-replace operation is _feasible_ at 
this stage, since we used exactly that system on the XHTML namespace id.
It will require a lot of thought, however.

As to finding a list of all our proprietary properties -- how can we do this?

This should IMHO probably be done at least one beta before release, to iron out 
any problems, since this is at least a moderately risky process, if not too 
difficult to manage. Therefore, nominating nsbeta3. (I would suggest nsbeta3
hardstop since we want to know for _sure_ that this is ready for FCS.)
Comment 10 David Baron :dbaron: ⌚️UTC-7 2000-06-16 09:56:27 PDT
All CSS identifiers recognized (and all properties) are in a list somewhere...
Comment 11 Pierre Saslawsky 2000-06-16 16:06:23 PDT
The recognized identifiers are organized as following:
    nsCSSAtomList.h:    pseudo-classes / pseudo-elements
    nsCSSPropList.h:    properties
    nsCSSKeywordList.h: values
Comment 12 ekrock's old account (dead) 2000-07-19 17:08:15 PDT
David, I doubt Pierre will have the time to do this. Is there any chance you 
could take on this bug, perhaps with his guidance?
Comment 13 David Baron :dbaron: ⌚️UTC-7 2000-07-19 17:18:29 PDT
OK, I guess I'll take it.  Hopefully I'll have time.

Pierre - the previous time I looked at the code, my impression was that there
were constants generated from the names of the properties.  It would be easier,
IMO, if we changed the names of the properties without changing the constants. 
This could introduce problems later if we decide we want to support both the
-moz- property and the new property with the same name.  Do you think it's
better to change the names of constants or leave them the same?

There are also some issues about what working drafts we consider stable enough
to use the names in the drafts...
Comment 14 ekrock's old account (dead) 2000-07-20 09:14:26 PDT
Thanks David. I can think of at least two acceptable ways of fixing this:

1) (easier) just *add* the new mozilla-native pseudo classes (so we're 
able to evangelize developers and they can Do The Right Thing by using the -moz- 
versions in their content, avoiding future upward compatibility issues if we 
have to change the behavior of the non-"-moz-" properties per future releases 
of specs) but leave the existing ones in and supported (although deprecated for 
external use) in case there are internal dependencies within the product on 

2) (harder but better if we can get away with it without causing regressions in 
the product) *change* the properties (and all instances of their usage within 
the product) from the "bad" names to the "good" names

Justification of nsbeta3 nomination to PDT team: the CSS specification requires 
that vendor extensions to CSS must begin with a hyphen; there should also be 
some kind of prefix (in our case, "-moz-") identifying where these extensions 
come from. Currently, our implementation is out of compliance with the CSS spec 
in this way because the Mozilla CSS extensions listed above do not have the 
-moz- prefix.

Not only is this a standards compliance bug, but if not fixed before FCS, it 
creates a very serious vulnerability for Mozilla's ability to be both 
standards-compliant and backwardly-compatible in the future. If these property 
names persist through RTM, not only would Mozilla have to retain the 
non-compliant property names in future releases in order to assure backward 
compatibility with content that had used them, but worse, the possibility exists 
that the CSS working group would define different semantics (behavior) in CSS3 
for the same non-prefixed names we've used. This would create a situation where 
Mozilla would either have to break the standard (by retaining its current 
behavior for b.c. and ignoring what the standard says) or break backward 
compatibility with content that had adopted these Mozilla extensions (in order 
to comply with the standard).

Because of the fact that external content and web applications will be written 
using these extensions (the developer-adoption "lock-in" effect in which we 
become unable to change our API due to external dependencies), it's crucial that 
we get this fixed before RTM, which means in nsbeta3 for safety. David Baron has 
taken on the work. Please call me if you're considering not approving this for 
Comment 15 Hixie (not reading bugmail) 2000-07-21 15:33:46 PDT
Another property which should be marked with -moz- is 'behaviour', since as I
understand it our implementation is very likely to differ from the BECSS spec.
Comment 16 ekrock's old account (dead) 2000-07-22 18:20:46 PDT
... and that should be "behavior," because I believe American English spelling 
is the standard for property names in the W3C specs and, yes? (e.g. 
we support "color", not "colour") ;->

um, yes. Sorry, I keep forgetting to misspell these words.... ;-)
Comment 18 Hixie (not reading bugmail) 2000-07-25 22:49:39 PDT
As per meeting with ChrisD today, taking QA.

David: It would be good to try to get this done right at the start of the 
beta3 cycle, since this is comparatively high risk, and we will want as much
time as possible to find bugs.

Note to PDT: The risk is not to external, existing pages, but to internal
demonstration pages and the chrome itself, so we should find problems very
quickly, if any do occur.
Comment 19 Pierre Saslawsky 2000-07-25 23:54:27 PDT
David, in response to [2000-07-19 17:18], I agree it would be easier to keep the 
constants as they are but, in addition to potentially future incompatibilities, 
I'm afraid it may bring a bit of confusion for those who work on the code as 
well. Let's keep the current scheme...

I think it is *vital* that this gets fixed ASAP now. We are fast approaching the
end of the nsbeta3 train, at which point something this big will never get 
approved. This is something for which I would *definitely* hold beta3.

If David cannot do this at this point, then we need to find someone else who
can. Pierre? You only have two open nsbeta3+ bugs... ;-)
Comment 27 David Baron :dbaron: ⌚️UTC-7 2000-08-25 13:33:08 PDT
Pierre - is it OK with you if I don't change the constants, at least not

Changing the constants is something that can be done one at a time, later on, if
desired.  Tracking issues with the chrome will probably be enough to handle when
I change the property names and values, so I'd rather not have to deal with tons
and tons of source changes too, at the same time.

Comment 30 Hixie (not reading bugmail) 2000-09-04 23:22:51 PDT
Andreww: That's all well and good if it is somebody from inside Netscape that
does it, but if it is a non-Netscape Mozilla contributor who does the work then
it is absolutely NOT their responsability to keep our internal tree up-to-date.
Say IBM had a "commercial" tree of their own, like we do, would any changes we
make to the Mozilla tree require us to fix the IBM tree as well? I think not.
Comment 31 David Hyatt 2000-09-05 00:08:16 PDT
I doubt this will affect the commercial build at all.  YOu have no XBL over 
there, so -moz-binding won't affect you.  That's the most prominent change out 
of all of these...

I use the P-field for sorting my bugs.  Leaving PDTP3 as indicator of PDT's
opinion.  This is P1 because it's the bug that is first on my list right now.
Comment 35 David Hyatt 2000-09-05 17:04:42 PDT
Hmmm. Consider that I have at least 2 crasher bugs related to the fact that the 
"behavior" property clashes with Microsoft's usage of the same property to load 
HTCs.  Changing this name to -moz-binding would be a very good thing, and 
ensures that we don't end up crashing on any page that happens to use HTCs.

Comment 36 ekrock's old account (dead) 2000-09-06 14:41:03 PDT
Marking crash per hyatt's comments. The last think in the world we want is for 
Gecko to be crashing on proprietary MS markup extensions as there's an 
increasing amount of that stuff floating around the web. That makes this issue 
now a PDT P1 in its own right.

list of properties that need work, from Ian Hickson
Comment 38 David Baron :dbaron: ⌚️UTC-7 2000-09-07 11:44:58 PDT
The above list was more than just properties.  The property renaming is done
except for the exceptions in the next two paragraphs, and the other work still
all needs to be done.

Regarding counter-increment and counter-reset, I can't find *any* implementation
of these properties, so I don't see a need to rename them.  I also see parser
errors where they're used in html.css.  What does removing them from html.css
do?  (I strongly suspect nothing.)

We also need to fix the DOM code not to work with the properties that we have
disabled via the CSS parser, or to work with them using their -moz- names.  This
may mean just changing an idl file and regenerating code, but I'm not sure.  See

I'm running out of time to work on things this summer and I really need to
finish up some other things too.  There's a chance I may still be able to help
with this, but I'm really not sure how much time I'll have next week.  So,
reassigning to pierre and clearing nsbeta3+ so he and his manager can reevaluate
it according to their priorities.

Comment 47 ekrock's old account (dead) 2000-09-24 13:52:38 PDT
I believe I've thought of a workaround web developers can use so they can 
write their content in such a way that it will permit us to rename these 
properties in the future without breaking their content. Marking relnote. 
Release notes should read:

"CSS extension properties in Mozilla that are not defined by any version of the 
CSS specification should have names prefixed with -moz-. For the first release, 
the following properties lack this identifying prefix: [list them]. Web 
developers should be aware of the following: (1) the use of these properties is 
unsupported and their current names are deprecated, so developers should avoid 
using this properties if at all possible; (2) the property names will likely be 
changed by adding -moz- in a future release, and in the same or a subsequent 
release, the old deprecated property names may be deleted as well; (3) because 
of (1) and (2), developers who find it necessary to use this properties in their 
CSS markup should include each declaration twice, first with the -moz- prefix 
(for forward compatibility with future version in which the property names may 
be modified and support for the old property names may be dropped) and second 
without the -moz- prefix (for compatibility with the first release of Netscape 
6). Note that it is important to place the declarations in that order (with 
-moz- first, without -moz- second) to handle a situation that might arise where 
a future CSS spec might use the same name as one of our mis-named CSS extension 
properties, and you would want the Mozilla CSS extension to get the higher 
CSS priority in the cascade to maximize the chances of forward compatibility of 
your legacy CSS markup with a future version of Mozilla in which both properties 
were supported.

Example of correct CSS markup usage:
FIELDSET { -moz-fieldset-content:1; fieldset-content: 1; }

(Can someone provide a valid sample value that we might actually set 
fieldset-content to? 1 is a total guess; I have no idea what this particular 
extension does.)

JavaScript developers should exercise the same caution in setting these 
mis-named properties through the DOM2 CSS interface. The best approach would be 
to create a variable useOldMozillaCSSPropertyNames and set it to true or false 
by sniffing the user agent, then create a variable to hold the name 
of each property you must set and conditionally set that variable to either the 
old name or the new name depending upon the Gecko datestamp. e.g. 

// for now, just hard code to true since we don't know from which Gecko
// datestamp release date (or whether) the names will be changed; if the 
// names are changed in a future release, you would change true to a
// client sniff of the Gecko datestamp string
var useOldMozillaCSSPropertyNames = true; 

var fieldsetContentCSSPropertyName = (useOldMozillaCSSPropertyNames ? 
"fieldset-content" : "-moz-fieldset-content")

When you need set the fieldset-content CSS property from JS, you would 
concatenate a string together with the command you wanted to evaluate, using 
this placeholder string to hold the value of the property, and then eval the 

All: please check my CSS/JS examples/syntax for any errors and make needed 
corrections. This approach is an ugly hack but it does provide forward 
compatibility. The best approach of course would be for developers to avoid 
using this mis-named properties entirely. And we may never drop the mis-named 
properties from the product because of the risk of breaking legacy content that 
depends on them; that decision will have to await a future release.
Comment 48 David Baron :dbaron: ⌚️UTC-7 2000-09-24 15:08:22 PDT
The whole point of this bug is that what we can't control is whether future CSS 
specs use properties that are currently extensions.  We're renaming to -moz- to 
avoid forward-compatibility problems.  If authors use something not defined by a 
current CSS spec, a future CSS spec could define it to mean something other than 
what the author meant.

However, the property renaming is done -- that's not the issue anymore.  The 
remaining stuff is all the other renaming (values, units, pseudos, &c.).
Comment 49 ekrock's old account (dead) 2000-09-24 18:47:47 PDT
Is the renaming done for (a) static CSS markup, (b) JS DOM access through DOM2 
CSS, and (c) XUL DOM CSS properties?
Comment 50 David Baron :dbaron: ⌚️UTC-7 2000-09-24 20:36:58 PDT
The property renaming is done for all 3.  It is done in the CSS parser and the 
CSS2Properties interface.  I think all other DOM use goes through the CSS parser.  
Perhaps it should be tested, though...
Comment 51 Hixie (not reading bugmail) 2000-09-25 01:00:01 PDT
Note that the biggest problem at the moment is with our pseudo-classes, which
is what the bug was originally filed about. ;-)

In particular it is very likely that :table, :table-row and so on will 
eventually be added to CSS, and it is very UNLIKELY that the meaning will be
the same. This is a major problem for future standards compliant authors.
Comment 52 ekrock's old account (dead) 2000-09-25 10:58:22 PDT
Is there a particular technical reason that we were able to fix this for the CSS 
properties but not for the pseudo-classes? I'm perplexed that we fixed one but 
not the other. If the problem truly only remains for the pseudo classes, someone 
please rename the Summary to reflect this.

If the pseudo-classes are still mis-named at this point, then I'm afraid we have 
to advise content developers to use my proposed workaround. Yes, it's ugly. Yes, 
David, in an ideal world content developers wouldn't have to do such things. But 
my job is about delivering the best product we can given the available time and 
resources in the real world and then helping developers write their code to work 
as well as possible on it. ;->
Comment 53 David Baron :dbaron: ⌚️UTC-7 2000-09-25 11:07:34 PDT
The only "workaround" available to content authors is *not to use* our
extensions that have not been renamed.  However, this is a forward-compatibility
bug.  The real problem that this bug causes is not now, it's later, after we fix
this bug or implement these values or pseudo-classes differently according to
later CSS specs.  Proposing workarounds doesn't make sense for
forward-compatibility bugs.

The reason the properties were done and not the others is that they are in
separate parts of the code, and I only had time to do one area.
Comment 54 Pierre Saslawsky 2000-09-25 11:32:54 PDT
David, if you have looked into it...
- Is it sufficient to rename the pseudos in html.css and nsHTMLAtomList.h (+ cpp 
files)? Or do you know if they are used in other css files?
- Which pseudos from nsHTMLAtomList.h have to be renamed? All?
Comment 55 David Baron :dbaron: ⌚️UTC-7 2000-09-25 11:38:30 PDT
All I know is what's in

nsHTMLAtomList.h looks easy to do, because the atom name doesn't depend on the
string, so we don't need to change code (although we probably should at some
point to clean it up).  My memory was that some of the others weren't so easy.

I haven't looked to see what CSS files use which pseudos, but LXR is good for that.

Adding rtm+. This is low risk and necessary for standards compliance.
Comment 57 Michael La Guardia 2000-10-02 16:40:16 PDT
Marking rtm- due to the existence of potential workarounds and lack of fix.
Comment 58 Pierre Saslawsky 2000-10-02 16:57:10 PDT
Sometimes the PDT team leaves me speachless. I wasn't allowed to work on this bug 
until it was approved for a fix, and now that it is approved, it is immediately 
denied because there isn't a fix. Are you telling me that I should have found a 
fix between Friday afternoon and Monday morning?

There isn't a workaround for this bug. Once we pollute the Net, it's very very 
hard to clean up.

Putting back to [rtm+] for reconsideration.
Comment 59 Pierre Saslawsky 2000-10-02 17:26:06 PDT
Back to [rtm need info] per the new policy ("When the engineer and manager agree 
to work on the bug, the bug should be [rtm need info] and when the reviews are 
all done, the bug should be [rtm+].")
Comment 60 Pierre Saslawsky 2000-10-02 17:31:36 PDT
Although, thinking about it... I don't want to work on something that is may be 
refused later because of some misconceptions, so back to rtm+.

Michael, why do you believe that we have some "potential workarounds"? Then if 
this bug has a reasonnable chance of being approved, please put [rtm need info], 
otherwise just [rtm-] again. Thanks.
Comment 61 selmer (gone) 2000-10-10 17:54:27 PDT

Changing [rtm need info] to [rtm-] per last week's discussion with PDT.
Unfortunately, this didn't make RTM. Developers should consider these property
names deprecated from the outset and subject to change and avoid building in
dependencies on their use.
Comment 64 Hixie (not reading bugmail) 2000-10-17 17:17:59 PDT
For the record: As mentioned previously, convincing developers not to use our
extensions has nothing to do with this bug. The problem will occur when CSS
_introduces_ a new feature that happens to have the same name as ours. Authors
will then be unable to use the new features until N6 is no longer in the market.
(e.g., if CSS3 introduces :canvas or :viewport, then N6 will choke on them.)
Comment 65 Uriel 2000-10-17 18:59:10 PDT
Don't you realize that this bug is going to make the work of thousands of web
developers a nightmare???
I'm sure they will remember you and your decision when they try to make their
pages work with NS6.(I worked with many web developers, and what they say when
they have this kind of problems isn't funny)
I really don't care about NS, but what really scares me is that they are going
to blame mozilla :( And that when mozilla 1.0 ships I'll be unable of use
standards without breaking netscape users.
But if you care about NS, I think the anger of web developers isn't going to do
any good to it.

To make clear Hixie comment:
This is going to make impossible the adoption of new standards until no one uses
NS6!! Do you really want that people use NS6? Or you only want to ship?

My only hope is that no one use NS6, it's really sad to say that about the first
product based on mozilla :(

P.S.: And if any one have some doubts:

P.P.S.: Sorry if I'm too rough, but it is really frustrating to see years of
hard work of many great hackers in standards compliance lost for this mistake :(

Hixie: Don't get discouraged. Keep the good work, you rock! and Mozilla 1.0 is
going to rock too ;)
Comment 66 ekrock's old account (dead) 2000-10-17 20:17:23 PDT
Ian: You overlooked an important point. The point you made (about Mozilla having 
proprietary behaviors associated with these property names potentially 
discouraging adoption of the properties if the W3C adds the same 
property names to a a future spec version with different behaviors) is 
valid. *However*, it is *also* important for Netscape to document that these 
names and the behaviors associated with them are subject to change so that 
developers don't build in dependencies on the *proprietary* behaviors of these 
names in the code they create in the meantime, or so that if they do, they 
compartmentalize those dependencies for easy future upgrading. *That* is what I 
was referring to.

Both of you: (1) This is an open source project. No one else stepped up to lend 
a hand on this bug, so don't slam Netscape only. (2) itself has 
said that what Netscape can do most to help web standards is to ship Netscape 6 
ASAP. The only way to do that is to close down development. The only way to do 
that is to not fix every outstanding bug. (3) You're overestimating the impact 
of this bug. First of all, it will be some time before the W3C releases new 
versions of specs, and there's no guarantee that all or any of these names will 
be used, and there's no guarantee that the property names will overlap, or if 
they do, there's no guarantee that the behaviors may not as well. Second, when a 
new W3C spec is released, it will in all likelihood be Netscape and 
that are implementing it first because we are implementing more web standards 
more deeply than anyone else. Third, we may get this fixed as soon as the first 
point release of N6. Fourth, there *are* workarounds (such as sniffing the 
browser version and then dynamically document.write()-ing out a link to one 
style sheet or another), and we can warn developers to use these approaches in 
the first place as a preventive measure if they use these properties so that 
these properties are only seen by N6 (not other browsers) in the first place. 
(4) Keep this bug in perspective. Where is the support of MS IE 5.5 for CSS1? 
What about the support of IE Mac 5 or Opera 4 for the DOM? We're implementing 
more web standards, more deeply, more consistently, across more platforms, 
simultaneously than any other browser engine available. If you're going to slam 
Netscape or anyone else about this particular bug, make sure to slam the other 
vendors proportionately for all the 1000+ cases where we get it right and they 
haven't even bothered to try.
Comment 67 Hixie (not reading bugmail) 2000-10-17 21:32:24 PDT
Eric: What you say is correct. I just wanted to make sure that the facts were
clear (hence my prefix "for the record").

For accuracy's sake:
   (1) is not a valid point, since the non-Netscape contributors to this project
       are aiming at Mozilla 1.0 or their own organisation's first release, and
       should not have to do things in time for *Netscape* deadlines. It is 
       Netscape that is releasing this product, the responsability for its bugs
       lies clearly on Netscape (since, AOL and marketshare issues aside, 
       Netscape could theoretically delay ship for this fix).
   (2) The last "word from the WaSP" was a farce, and has no respect in the 
       standards-support community. IMHO the WaSP no longer speaks for that
       community, or if it does then it is fragmented.
 (3.1) This bug does indeed only have *potential* impact. However it is an
       impact that has been felt before, e.g. with IE's total mess-up with
       positioning (a mess-up that has caused a great deal of time to be wasted
       in the CSS community). I was hoping to avoid that as much as possible.
       Thankfully a more recent development (changing pseudo-elements to using
       two colons as a prefix) _may_ mitigate most of the issues here.
 (3.2) We can but do our best! :-)
 (3.3) That would be great.
 (3.4) Yes, this is the only workaround; a poor workaround indeed. I know that
       you are very aware of the awful problems we are having evangelising
       the fixing of all the existing browsing sniffing code.
   (4) I'll remind you that as far back as September 1998 I have been slamming
       Microsoft, Opera, and Microsoft again for their failures.

Whew. Let's get this baby out of the door ASAP so we can get back to fixing
these bugs! :-)
Comment 68 Gervase Markham [:gerv] 2000-10-23 15:31:31 PDT
It seems unclear to me whether this bug requires either of a "developer" or 
"user" release note. If anyone feels it does, can they please draft one and then 
nominate with the relnote-user or relnote-rtm strings in the Status Whiteboard.

Jonas: You can assume the list is up to date. It might be slightly inaccurate
in places, but that shouldn't be a big issue (dbaron?).

Yes, it's safe to change things that were in Netscape 6.0 for Mozilla 1.0, since
all the properties that people are likely to use (opacity, border-radius, float-
edge) already have the -moz- prefix.
Comment 76 Kevin McCluskey (gone) 2002-02-05 15:34:15 PST
Moving to Mozilla1.1. Engineers are overloaded with higher priority bugs.
Comment 77 Hixie (not reading bugmail) 2002-02-06 03:15:15 PST
This really should be fixed by 1.0. It's basically an API, and we want to freeze
APIs for 1.0, right?
Comment 78 Kevin McCluskey (gone) 2002-02-22 09:47:00 PST

work post Mozilla1.0.
Comment 79 Gervase Markham [:gerv] 2002-03-27 15:23:44 PST

Here's an update on info I can find, and implementation notes for fixing this
bug. Please could you cast your eye over it and tell me if I've got something wrong?

Anything with " - none" beside it means that a grep of all the .css files in the
tree failed to find a use of that word.

" - unable to grep" means the word is so common in other contexts that it's very
hard to see if the word is used by grepping.


* new units to -moz-
I can't find a use of these units, but it's hard to grep for. What are they?

* new values to -moz-
These names are changed in the file:
copy - none (I don't think)
alias - none
context-menu - none
grabbing - none 
spinning - none
count-up - none 
count-down - none 
count-up-down - none 
window [1]
document [1] - none
workspace [1] - none
desktop [1] - none
info [2] - unable to grep
dialog [2] - unable to grep
button [2] - unable to grep
pull-down-menu [2] - none
list [2] - unable to grep
field [2] - unable to grep
menu [3] - unable to grep
Affected files:

* unknown values [4] - not sure about these!
ignore - property of -moz-user-focus, -moz-outliner-image
noshade - none
paragraph - none
start - property of -moz-box-align, -moz-box-pack, -text-align.

* properties to -moz-
background-x-position is now -x-background-x-position
background-y-position is now -x-background-y-position
behavior              is now -moz-binding
border-x-spacing      is now -x-border-x-spacing
border-y-spacing      is now -x-border-y-spacing
box-sizing            is now -moz-box-sizing
clip-bottom           is now -x-clip-bottom
clip-left             is now -x-clip-left  
clip-right            is now -x-clip-right      
clip-top              is now -x-clip-top
counter-increment     unused? Only used in tests
counter-reset         Used in html.css
float-edge            is now -moz-float-edge
key-equivalent        is now -moz-key-equivalent
opacity               is now -moz-opacity
outline-color         is now -moz-outline-color
outline-style         is now -moz-outline-style
outline-width         is now -moz-outline-width
resizer               is now -moz-resizer
size-height           is now -x-size-height
size-width            is now -x-size-width
text-shadow-color     is now -x-text-shadow-color
text-shadow-radius    is now -x-text-shadow-radius
text-shadow-x         is now -x-text-shadow-x
text-shadow-y         is now -x-text-shadow-y
user-focus            is now -moz-user-focus
user-input            is now -moz-user-input
user-modify           is now -moz-user-modify
user-select           is now -moz-user-select

All of the renamed ones have a 
// XXX bug 3935 
comment beside them. Does that mean that this bug fixed them, or there is still
more to do?

For the next three categories, I assume that what is required is to change the
name in the .h file, and then change all the css files which reference that
pseudo. Is that right?

* nsLayoutAtomList pseudos to -moz-
These names are changed in the file:
Affected files:

* nsHTMLAtomList pseudos to -moz-
These names are changed in the file:
:body-column - none
:first-letter - none
:frameset-blank - none
:hframeset-border - none
:ib-pseudo - none
:label-content - none
:legend-content - none
:placeholder-frame - none
:vframeset-border - none
Affected files:

* nsCSSAtomList pseudos to -moz-
These names are changed in the file:
:disabled - none
:drag-over - none
:drag - none
:enabled - none
:menu - none
:root - none
:selection - none
Affected files:

[1] - need to be split up; these are the values for 'font'
[2] - only do these if those marked [1] are done
[3] - needs to be split up, this is the 'display' value not the others
[4] - I cannot find ANYWHERE where these are used 

So, in summary: 
- I think I know how to fix the last three categories (the pseudos), and it's
not hard. 
- All the properties apart from text-transform and maybe counter-* seem to be
fixed already (and that text-transform is only used in test cases.)
- A lot of the values don't seem to be used any more. I can fix some of them;
tracking down others will be quite a bit of work because the words are common
- I have no idea about the "ch" unit.

Please advise :-)

The nsCSSKeywordList.h change omits inline-block ==> -moz-inline-block (see also
bug 118711).

Taking this bug and targetting 1.0, although Gerv's help is welcome.

Comment 82 Gervase Markham [:gerv] 2002-04-02 14:56:43 PST
Here's a question:

there are lines like:
CSS_PROP(-moz-appearance, appearance, REFLOW)

The comment says that:
Entries are in the form: (name,id,effect). The second param should be the same
as the first with "-" replaced with "_". This is not the case for a lot of the
"-moz-" properties - the second param is missing the -moz-.

Checking nsCSSPropList.cpp shows that we don't actually use the second param
there - so does this matter at all?

I have a patch for the last three things of the five (the pseudos), but I need
more guidance on the first few from hixie or dbaron.

Comment 83 David Baron :dbaron: ⌚️UTC-7 2002-04-02 15:10:37 PST
The second parameter is appended to eCSSProperty_ in nsCSSProps.h, and that enum
value is used in the code.  The name that is parsed is the first parameter. 
It's nice if they're consistent, but when I did the first patch for this bug I
didn't want to make massive changes all over the code.

Patch v.1 - fixes all pseudos

Most (maybe all) of the ones you changed in nsCSSAtomList.h are in the CSS3
selectors draft, which is in CR, so we should be implementing it without -moz-.

:first-letter and :first-line are in CSS1, so they shouldn't be changed.
Comment 86 David Baron :dbaron: ⌚️UTC-7 2002-04-03 15:38:55 PST
Regarding comment 79, I agree that we should change the counter-* properties,
but I don't see the reason for changing text-transform.  I'd need to look
through the nsCSSKeywordList list more closely and check the spec, but I suspect
some of those keywords may be real.  (It would be useful to see a list of the
properties for which they are accepted.)  There may also be some that need to be
split between a -moz- value and a non -moz- value (for different properties). 
And noshade and paragraph should just be removed from nsCSSKeywordList.h.

dbaron and others: I'm happy to fix this bug as soon as someone with knowledge

prefixing. If a definitive list can be defined, I'll produce the patch.

This patch looks good.	I'll try to check later today that there aren't any
other property or value changes that you need to make and go through in a
little more detail.

How did you search CSS files in the tree to decide what to change?  The changes
you found look like about what I would expect, since I wouldn't expect chrome
CSS to be using any of these properties or pseudo-elements.
Comment 94 Gervase Markham [:gerv] 2002-04-13 03:15:35 PDT

The following can just be removed instead of renamed, since no code uses
them, so there's no point wasting the memory for unused atoms:


Could you mark these two changed lines:

-CSS_PROP(counter-increment, counter_increment, REFLOW)
-CSS_PROP(counter-reset, counter_reset, REFLOW)
+CSS_PROP(-moz-counter-increment, counter_increment, REFLOW)
+CSS_PROP(-moz-counter-reset, counter_reset, REFLOW)

with "// XXX bug 48973" at the end, to be consistent with the key at the
top, unless you want to change the key at the top to something more
sensible (e.g., by filing a new bug about the 48973 issues).

With those two minor changes, r=dbaron.

selectionPseudo and dragPseudo can also just be removed.  (selectionPseudo is
actually part of CSS3, but I don't forsee implementation in the near future, and
the one place it's used in the current code just slows things down, and would
only make sense if it were a pseudo-class rather than a pseudo-element anyway

I meant nsCSSKeywordList.h.  And it probably should be a separate patch -- it
will may be more complicated than this one.

And I can tell you didn't compile that patch yet.  You're missing changes to

patch for nsCSSKeywordList changes
Comment 108 David Baron :dbaron: ⌚️UTC-7 2002-04-24 22:00:46 PDT
I made a few decisions that probably need to be discussed about what should be
disabled and what shouldn't.  (For example, I didn't disable 'text-align:
start', because I think that CSS3 module is stable.  I did disable
'inline-block' and 'inline-table'.)

Someone will probably have to run the tool in bug 139943 over the commercial
tree with this patch installed to search for potential changes that need to
happen there.

patch for nsCSSKeywordList changes, v. 2

I missed two keywords that could be completely removed since they're unused.

patch for nsCSSKeywordList changes, v. 3

This patch removes 'display: menu', 'font: theme', and 'color: theme'
completely, since hyatt says they're not used anymore.	There was some code
associated with copying around the values of the latter two (but not using it)
that is also removed.

Fix checked in to MOZILLA_1_0_0_BRANCH, 2002-04-30 20:55 PDT.

Since we're currently in the state we should be in, or at least pretty close,
I'm marking this bug fixed.  I filed bug 141397 for the long-term maintainance
of this state, with the intention that it be revisited every few milestones.
Comment 117 David Baron :dbaron: ⌚️UTC-7 2002-04-30 21:23:55 PDT
I almost forgot:  many thanks to Gerv and Hixie for considerable help in fixing
this bug.
Comment 118 Hixie (not reading bugmail) 2002-05-23 15:54:38 PDT
Verified on trunk and branch by checking the following files have been updated
to use sanitised names:
   mozilla/content/shared/public/nsHTMLAtomList.h well as various others.
Comment 119 David Baron :dbaron: ⌚️UTC-7 2004-04-05 15:07:33 PDT
Hmmm.  We managed to miss :first-node and :last-node.
Comment 120 Hixie (not reading bugmail) 2004-04-06 10:54:32 PDT
That was intentional.
