I have decided to finally take on the enormous task of getting rid of the use of atoms from nsICharsetConverterManager. as a part of this, I am also eliminating the requirement to call GetCharsetAtom() - it is rediculous that every call to GetEncoder/GetDecoder has to be prefixed by a call to GetCharsetAtom() in order to do alias resolution. instead, GetEncoder/GetDecoder should just automatically do alias resolution. As a part of this, I'm making sure that the argument to GetEncoder/GetDecoder takes a IDL "string" - a const char* since charset names are by definition ASCII... the ripple effects of these changes are pretty extensive but 90% of the code this affects is simplified due to reduced string conversion, reduced alias resolution, and so forth. Overall this should result in some much simpler codepaths and a generally smaller footprint.
a few other changes: - removing the old nsICharsetConverterManager, and renaming nsICharsetConverterManager2 over to nsICharsetConverterManager. - within intl, this resulted in interface changes in nsIPlatformCharset, nsIConverterInputStream, nsICharsetAlias, nsIScriptableUConv, and nsIPosixLocale - all mostly simplification
*whew* - I finally finished this. its going to be a beast! Well, I'm almost finished - I've done the work on linux and windows.. next comes mac and then we gotta notify the ports due to impacts in gfx/widget
ok, here's the complete patch. Whew.
Comment on attachment 124590 [details] [diff] [review] remove nsIAtom from most of the API Requesting reviews from Simon and Blizzard. This is a huge patch I know but it reallys simplifies some code and thus is a great footprint win. for my own planning I'd REALLY like to get some ETAs on this.. if you're super-busy, please suggest an alternate reviewer - blizzard, I don't know who else does i18n super-reviews? In my next comment, I'll explain all aspects of the bug.

ok, here's what's going on here... for the reviewers: 1) I got rid of nsICharsetConverterManager2 and rolled it into nsICharsetConverterManager, so there is now a single interface for this stuff, and it is in IDL. 2) I got rid of all this silly atom stuff. the atoms were really just being used as a cheesy way to force people to go through nsICharsetAlias. In the old world, you used nsICharsetConverterManager2::GetCharsetAtom() to convert an charset string like "x-sjis" to its equivalent, like "Shift_JIS" and then THAT string would be converted to an atom, that you'd pass to GetUnicodeEncoder/GetUnicodeDecoder. This was just silly. There is really no value in using atoms as the charset strings were not used in any hashtable, and the atoms were often short-lived. it meant creating this temporary object on the heap (and storing it in the atom table) using it once, and then usually destroying it immediately afterwards. Now, GetUnicodeEncoder/Decoder goes through nsICharsetAlias every time - there was not a single consumer that wouldn't have wanted to go through the alias resolver. Since I didn't need Atoms anymore, I switched over to just using strings. For absolute simplicity, I used the IDL type "string" because these strings are usually VERY short (less than 16 characters) and ALWAYS ASCII. By definition, charset names cannot be encoded in any other charset. The advantages of using nsACString& were outweighed by the overhead of creating an nsDependentCString. I wrestled with this decision quite a bit, but in the end I think "string" is really the right thing here. 3) This also meant simplifying other methods in nsICharsetConverterManager to take ASCII strings rather than atoms. The one exception was getCharsetLangGroup() - this should eventually be changed to use raw strings, but that method doesn't really touch the code I was changing. I'd rather do that in a seperate patch (this one is big enough!) 4) Some of this conversion had a rippling effect through the i18n APIs - which included switching lots of i18n APIs over to using nsACString& or "string" - I tried to simplify where it made sense, and avoid unnecessarily changing excess code. I hope the reviewers will bear with me when they see calls to NS_LossyConvertUCS2toASCII(). 5) And of course, there are all the changes to the rest of the tree. In some cases it was as simple as changing the #include's from nsICharsetConverterManager2.h to nsICharsetConverterManager.h, and in other cases it involved reworking of existing APIs elsewhere in the tree. I almost every case it resulted in simpler code, and almost always faster because of less UCS2/ASCII/UTF8/etc conversion of charset names. 6) Finally, I revved the IID's in all the interfaces I changed, except for mailnews - revving IIDs was a huge pain and I really ran out of steam by the time I got to mailnews. My guess is that there aren't really any plugins/add-on's that use the mail APIs, or at least the ones I changed, which were more low level (nsIMessenger, nsIMailNewsUrl, etc) *whew*

Comment on attachment 124590 [details] [diff] [review] remove nsIAtom from most of the API I'm just remembering that simon (fraser) also does reviews, so I'm asking him as well. Oh two other things: - for anyone reading this bug or wants to help out, I can certainly use the review - even the nitpicking reviews will lighten the load for simon and simon. - we'll need ports work done here - you just need to apply the patch and then start building. I'll try to spread the word.

Alec, the code in nsCSSLoader no longer needs to resolve charset aliases with this change, does it?

Comment on attachment 124590 [details] [diff] [review] remove nsIAtom from most of the API Firstly, thanks a lot for fixing all these cases. It must have been really tedious. > there was not a single consumer that wouldn't have wanted to go through > the alias resolver. It's strange that you reached that conclusion after fixing all this. At the beginning, I thought similarly (although I suspected that there might be a few exceptions). After going through the patch, I concluded that what I had thought of as an exception (no need to resolve aliases) is actually the norm (at least for |GetUnicodeEncoder|.). Given this, I think we're better off with, in nsICharsetConverterManager, nsIUnicode(En|De)coder GetUnicode(En|De)coder(in string, in bool) than with nsIUnicode(En|De)coder GetUnicode(En|De)coder(in string) >Index: extensions/spellcheck/src/nsSpellCheckUtils.cpp .... >@@ -112,7 +112,7 @@ > > nsresult rv; > >- nsCOMPtr <nsICharsetConverterManager2> ccm2 = do_GetService(NS_CHARSETCONVERTERMANAGER_CONTRACTID, &rv); >+ nsCOMPtr <nsICharsetConverterManager> ccm2 = do_GetService(NS_CHARSETCONVERTERMANAGER_CONTRACTID, &rv); Nit.

Would it be a bad idea to add an optional third argument to |GetUnicodeEncoder| indicate the alias resolution has to be skipped? |GetUnicodeDecoder| does not need this facility. Ah.... I realized that we can't have an optional argument in idl (can we?)..

The current code doesn't go via charsetAtom (i.e. no alias resolution) and that's probably all right provided that |GetSubmitCharset| returns the canonical name. >Index: widget/src/gtk/nsClipboard.cpp > nsCOMPtr<nsICharsetConverterManager> ccm = do_GetService(NS_CHARSETCONVERTERMANAGER_CONTRACTID, &rv); >- rv = ccm->GetUnicodeDecoder(&platformCharset, getter_AddRefs(decoder)); >+ rv = ccm->GetUnicodeDecoder(platformCharset.get(), >+ getter_AddRefs(decoder)); I'm a bit suspicious of what's going on in nsClipboard.cpp (that's off the topic here, though). Anyway, here the current code doesn't go via charsetAtom, either. Some charset names used here are hard-coded and others are likely to have been stored in canonical names so that going through the alias resolution again could be a waste. >Index: widget/src/gtk/nsGtkIMEHelper.cpp >+ manager->GetUnicodeDecoder(charset.get(), &mDecoder); again no atom here. >Index: widget/src/gtk/nsWindow.cpp >+ rv = ccm->GetUnicodeEncoder(platformCharset.get(), getter_AddRefs(encoder)); ditto... >Index: widget/src/mac/nsMacControl.cpp >+ nsCAutoString fileSystemCharset; > GetFileSystemCharset(fileSystemCharset); >+ rv = ccm->GetUnicodeEncoder(fileSystemCharset.get(), &mUnicodeEncoder); ditto... >Index: widget/src/windows/nsFilePicker.cpp >+ rv = ccm->GetUnicodeEncoder(fileSystemCharset.get(), &mUnicodeEncoder); same here... >Index: widget/src/xpwidgets/nsPrimitiveHelpers.cpp > nsCOMPtr<nsICharsetConverterManager> ccm = > do_GetService(NS_CHARSETCONVERTERMANAGER_CONTRACTID, &rv); >- rv = ccm->GetUnicodeDecoder(&platformCharset, getter_AddRefs(decoder)); >+ rv = ccm->GetUnicodeDecoder(platformCharset.get(), >+ getter_AddRefs(decoder)); same here... >Index: xpfe/appshell/src/nsAppShellService.cpp >- rv = ccm->GetUnicodeDecoder(&aCharset, getter_AddRefs(decoder)); >+ rv = ccm->GetUnicodeDecoder(aCharset.get(), getter_AddRefs(decoder)); again.. >Index: xpfe/components/bookmarks/src/nsBookmarksService.cpp >- rv = charsetConv->GetUnicodeDecoder(&defaultCharset, getter_AddRefs(mUnicodeDecoder)); >+ rv = charsetConv->GetUnicodeDecoder(defaultCharset.get(), >+ getter_AddRefs(mUnicodeDecoder)); > } >@@ -1069,13 +1072,13 @@ .... >- nsAutoString charsetName; >+ nsCAutoString charsetName; > if (NS_SUCCEEDED(rv = gCharsetAlias->GetPreferred(charset, charsetName))) > { > if (!charsetName.IsEmpty()) >@@ -1092,7 +1095,7 @@ > (nsISupports**)&charsetConv); > if (NS_SUCCEEDED(rv) && (charsetConv)) > { >- rv = charsetConv->GetUnicodeDecoder(&charset, decoder); >+ rv = charsetConv->GetUnicodeDecoder(charset.get(), decoder); It doesn't look like the resolved charset name is stored anywhere.

followup to comment 8: killing the spurious braces fixed the bustage - build seems to work fine now
jshin: thank you SO much for the review. I know it was a beast. Appearently I just didn't understand the alias resolution stuff as well as I thought! since you seem to have found the cases where we don't need the resolution, I will change those to GetUnicode[En|De]coderRaw() - a version which does not use the alias resolution. I thought about the extra boolean but I think a seperate function call is more concise and makes the consumers easier to understand. As for some of the other stuff, like: - why we don't switch to nsACString& from char** and so forth - I am trying to fix the minimal case, which as you can see is pretty huge thus far. Do you mind if I get those in another patch, a second round of fixes? - As for nsUConvCID.h, do you mind if I get that in another patch as well? I agree that those should be in a seperate file but there are SO many places that #include nsICharsetConverterManager.h, that it would be very painful to revisit them all. bz: thanks also for the review, it sounds like jshin has covered that case, I'll use the GetCharsetEncoderRaw() dwitte: Is there a missing brace in my patch, or is there just missing stuff? I forgot that gtk2 will be one of the ports that I need porting work on - thanks for helping! is there any chance you can post a patch with the changes you had to make, and I'll incorporate it into my work? (I'm assuming the changes will be in new files that this patch doesn't cover)

Attached patch OS/2 patch (obsolete) — Splinter Review
Here's the OS/2 patch
Alec, I didn't read any part of this patch, actually... so no review here. jshin, the CSSLoader just wants a string it can pass to GetUnicodeDecoder to come out with a decoder. It sometimes has strings that do need resolution (eg coming from HTTP or from the sheet) and sometimes strings that do not need resolution (coming from nsIDocument). Right now we resolve aliases by hand in a bunch of places in that code; I ended up writing a helper function to do it, because it was such a pain. So from the CSSLoader point of view, it would be much preferable to just have intl handle things reasonably and not have to do all that work.

Attached patch gtk, gtk2 and bustage patch (obsolete) — Splinter Review
alecf: np... this stuff looks nice :) as requested, this patch does a couple things... 1) fixes bustage in xpfe/components/nsInternetSearchService.cpp 2) applies your work to the gtk2 port 3) fixes some general string-class usage in gtk & gtk2 (not required for this work, but I just noticed some silly stuff on a cursory glance over the code, and felt like fixing it) if you'd rather we stick to basics, I can post a patch without the misc string changes. (you need to apply this patch _on top_ of yours, btw... also, i've compiletested gtk2, but not the gtk portion which I modified, so your request for gtk port testing still applies)
cool, thanks for the patch - I'm really surprised to see that bustage in gtk and nsInternetSearchService, I've gotta say. The original patch still builds on gtk/osx/win32 for me.. odd (perhaps it isn't applying cleanly now?) But is there any chance we could do without the string cleanup? I will GLADLY sr= any string cleanup later, but I want to keep this patch to the absolute minimum, given its current size...(364k without the os2 or gtk2 patches)

this avoids the string cleanup (except for one spot in widget/src/gtk/nsClipboard.cpp which WAS related to your changes, where I made an obvious correction) as before, this applies on top of your patch.
Attachment #124816 - Attachment is obsolete: true
Alec, all you wrote is reasonable. BTW, what are you gonna do with GetCharsetLangGroup()? It's not used as often as GetUnicode(De|En)coder, but it has the same issue. In nsFontMetrics(GTK|Xlib), charset names are coming from the hard-coded arrays (nsFontCharSetInfo types) with canonical names (the current code should have used NS_NewAtom instead of GetCharsetAtom2()) so that no resolution is necessary. In a few other places (mailnews, intl/locale), it's coming from external sources and we need to resolve aliases. > jshin, the CSSLoader just wants a string it can pass to > GetUnicodeDecoder to come out with a decoder. OK. I see. So, CSSLoader doesn't care whether mCharset is canonical or not. When mCharset is used to get a UnicodeDecoder for CSSLoader (nsIUnicharStreamLoader), we just have to make sure that GetCharsetDecoder() (that does resolve aliases) is invoked. I tracked it down and found that it's http://lxr.mozilla.org/seamonkey/source/intl/uconv/src/nsConverterInputStream.cpp#50 At the moment, it's not resolving aliases. Why doesn't it? If it did, ResolveCharset() in nsCSSLoader.cpp wouldn't be necessary even without Alec's patch, would it? Anyway, in nsConverterInputStream we have to make sure that GetUnicodeDecoder() with the alias resolution is called. In addition, I guess we have to make it clear that charset in nsIUniCharStreamLoader is not necessarily a canonical name. (http://lxr.mozilla.org/seamonkey/source/netwerk/base/public/nsIUnicharStreamLoader.idl#109)
dan, again thanks for helping me out here! This is very helpful mike, thanks for the OS/2 stuff, I'm incorporating it now jshin, I'm making a getCharsetLangGroupRaw() to cover the same case it sounds like the nsCSSLoader stuff is going to be pretty straight forward, and that I may have possibly fixed a bug by using the alias-resolving version of GetUnicodeDecoder :) Thank you SO much for going through and figuring out which cases needed the raw version...that makes my life much easier. Anyhow, I'm updating the patch to address all of jshin and simon's reviews.

ok, I could really use some more reviews on attachment 124846 [details] [diff] [review] - especially from jshin and smontagu. The one thing I forgot was to change all the "ccm2" variables over to 'ccm' - I've done that now in my local tree, but its not a large enough change to justify a new patch.
Comment on attachment 124846 [details] [diff] [review] remove nsIAtom v2 looking for a r=smontagu AND a r=jshin... thanks guys!

Attached patch mail compose window fix (obsolete) — Splinter Review
ok, this fixes all the stuff in MsgComposeCommands.js, which was doing all sorts of goofy things with charsets and such. This gets applied in addition to the above patch. I used LXR to search for any other occurences of this stuff, and this is the only one I found.. go figure!
To nhotta: Can you answer my question about nsTextToSubURI in the following (I'm sorry it's in the middle.) re: attachment 124846 [details] [diff] [review] Summary : 1. I ended up checking (mostly) raw vs non-raw. (Simon may wish to spend more time on nsCharsetMenu.cpp, nsScriptLoader.cpp, nsCharsetConverterManager.cpp) 2. Some observations: a. Whereever a string literal is directly passed to GetUnicodeXXX() or NS_NewAtom("...") is used, it's completly safe to use GetUnicodeXXXRaw(). In intl/uconv, gfx/src, mailnews and other places, there are many cases of non-raw version of GetUnicodeXXX invoked with UTF-8, GB2312, EUC-KR, x-euc-tw, ISO-8859-7, ISO-8859-1, x-user-defined, x-imap4-modified-utf. An example is shown below: Index: extensions/xmlextras/base/src/nsDOMParser.cpp + rv = charsetConv->GetUnicodeEncoder("UTF-8", getter_AddRefs(encoder)); A subset of the canonical charset names are listed in http://lxr.mozilla.org/seamonkey/source/intl/uconv/src/charsetalias.properties Why a subset? Because XLFD names and other internal charset names don't need the alias resolution and developers are supposed to use correct names for them when hard-coding them in the source code. Others are listed in http://lxr.mozilla.org/seamonkey/source/intl/uconv/src/charsetdata.properties b. Unless it's obviously a mistake in the old code(as we found earlier), we can replace GetUnicode(En|De)code(char *,...) or GetUnicode(En|De)code(NS_NewAtom(char *),...) with GetUnicode(En|De)coderRaw(char *,...). In most of cases, charset names passed are already canonical because they come from platformCharset/filesystem charset/other sources known to provide the canonical name. In what follows, I list some cases (but not all). Doing this would not introduce a regression although we may be preserving bugs as well. c. The opposite case of b. Unless it's obvious (I identified several in the previous comment and found a couple of more here), we can just use non-raw methods when charsetAtom is used in the old code. This item has null effect on the patch, though. :-) d. When the resolved charsetAtom is stored in the old code (in member variables), we have to store the resolved charset name. Your patch already did that, but there's a case you might have missed. (nsIContentSerializer. see comment further down.) 3. As far as 'raw vs non-raw' is concerned, I just realized that I could have edited the patch directly and sent it to you off-line instead of commenting on that. It'd have taken less time ......

And how about removing ResolveCharset() in nsCSSLoader.cpp?

alecf, thank you for taking care of this beast. r=jshin as we talked off-line, I'll hunt for more spots for 'Raw' after this gets landed.
more bustage... sorry alecf :/ this fixes firebird's forked nsBookmarksService.cpp. I did this by blindly applying the changes to mozilla's version, so please double-check I did the right thing. also removes a spurious #include I noticed (you had two of the exact same #include in that file) thx for fixing message compose, it works now. :)
So the converter input stream calls GetUnicodeDecoder, which now does alias resolution? Again, could we remove all the code in nsCSSLoader that is not needed as a result?
bz, let's lift this behemoth patch off alecf's shoulder :-) While bugzilla was down (6 - 7 hrs ago), I told alecf that I'd take care of nsCSSLoader.cpp and TestUconv.cpp after the current patch gets landed. Sorry I forgot to mention that in my prev. comment.

Is anyone looking at the "speedracer" tinderbox bustage (http://tinderbox.mozilla.org/showbuilds.cgi?tree=SeaMonkey-Ports) ?
Line 361 of nsCharsetConverterManager.cpp appears to declare an unused variable.
I don't see the warning/unused variable in nsCharsetConverterManager.cpp? (though I fixed the one in gfx)
I'd like to submit this patch to the mozdev spell checker folks to fix the spell checker if Alec says my fix is correct.
Comment on attachment 125527 [details] [diff] [review] patch for the mozdev spell checker you are correct, sir... though personally I'd change "mCharset" to be an nsCString rather than an nsString, then you can avoid all temporaries and conversions... (and if you do still have conversions, take a look at bug 209220 for the next set of conversions - that one fixes APIs on basically all of gecko/docshell/editor/etc...)
