Two of my IMAP folders, "r&AOk-pertoires" and "wallace&-gromit", are not being displayed correctly in the folder pane.
Currently waiting for the converter (bug 6983). Reassigning to firstname.lastname@example.org. Adding email@example.com, firstname.lastname@example.org to cc.
Are you saying I should be writing a utf-7 converter? I must be missing something. I know our code is #ifdeffed out, but I thought we were waiting for something from the i18n group.
No, Cata is going to write the converter. When the bug 6983 is resolved, please enable your code and resolve this bug. Sorry for the confusion.
M-UTF-7 converter is now bug 6814.
The converter was checked in earlier this week (6814). Is this just a matter of turning on/off the #ifdef? If so, can we do this for M7?
No, I have to write code to invoke the converter, which is code that is not written yet. I have other major features to do for m7.
*** Bug 8504 has been marked as a duplicate of this bug. ***
Are these converters thread safe? Can I call them from a non-mozilla main thread?
I don't really understand your questions: being able to call a converter from a non-mozilla main thread does not necessarily mean that the converter is thread-safe. A converter is not thread-safe: it has internal state and its methods are not synchronized. But why do you need it to be thread-safe?! You can't have two simultaneous users for it anyways. (internal state in some stateful decodings like UTF-7...) However, a converter can be called from any thread, as long as it is only one. The rule should be: if you need to call some converter from another thread, just instantiate a new component, a new converter of the same type. As a side-point, a converter can be reused by resetting its state: call Reset(). Hope I helped. Please let me know if you have any other questions.
sorry, I really meant : is the converter code thread safe? It sounds like it is. It's just that the imap code in the past always assumed that none of the code it called was thread-safe, so it would proxy over to the mozilla thread to do things like utf7 conversion.

fixed in nsImapProtocol.cpp to convert to unicode and then back to 8 bit ascii.
** Checked with 6/25/99 Win32 M8 build ** I have 2 types of IMAP folder names -- Latin 1 8bit characters and Japanese. Latin 1 names are showing OK but Japanese names are not. Each Japanese character is displayed as a dot instead. Since Modified UTF-7 converters are shown to be working now without errors, my assumption would be that is't not the converter. You mentioned something about using UTF-7 conversion. Is this taking place in this fix. We do have 2 outstanding bugs for UTF-7 converters, Bug 6983 and Bug 8343. For now, I'm ging to re-open this.
I have a question about IMAP folder summary files and Windows file system. If I make a Latin 1 8bit folder under US Windows and then refer to the same IMAP folder on a dual boot machine under Japanese Windows, Messenger will create another folder name file of the same thing but without the accents. So if the original Latin file name was "e'cho" (where ' indicates an acute accent), then on the Japanese system, it will create a file named "echo" without the accent. Thus I end up having 2 folders of the same thing. It seems like the Windows files system cannot somehow identify the existing one on the hard disk with what it is finding on the server. My question is: How can we avoid this? Is there a way to save IMAP folder names locally in such a way to be able to read them correctly under any Windows systems? Related question is what charset is the folder name saved currently? Does it have dependency on the locale of the OS?
This is as I expected - we convert back to 8 bit ascii, as I mentioned above, so non 8-bit ascii characters, e.g., Japanese, aren't going to work because (I assume) the converter really does convert them to Unicode. Switching the imap code to use unicode strings will be a lot of work, and will be done by m9 at the earliest - I suspect it may have to wait for necko to finish landing because a lot of the code involved is changing to support necko. We do save the real, decoded imap folder name locally, in the .msf file, and compare it against the server name. We're planning to save the m-utf-7 folder name, as we discussed a couple months ago, and compare against this instead, because it does not depend on locale.
Clearing Fixed resolution since this bug has been reopened.
Summary: IMAP: does not interpret M-UTF-7 in folder names → IMAP: does not interpret double byte M-UTF-7 in folder names
changing summary to reflect remaining bug.
Not going to happen in m9
moving to m11 - I'm reworking our inter thread communication to use nsisupports proxying, which will make it easier to do this.
(target milestone is M11 or M12 - add to mail beta tracking bug)
This isn't making B1 - we decided to work on performance instead.
I think now that we should try to get this into B1. Anyone have any opinions?
Yes, this would be great to have in B1. This will a lot help to get Japanese users to use B1.
Marking M14 to match last comments
Target Milestone: M15 → M14
Marking the keyword as Beta1.
Phil, I thought we weren't going to make this a beta stopper.
bobj, we need some input for pdt. pdt+? needed for beta1?
This is a Beta1 requirement. If this is not fixed, then Japanese users with existing IMAP accounts will not be able to correctly see any folders with Japanese names. Also, if a user creates a Japanese folder name, then it will be created using a corrupted string. The folder will probably not be accessible (maybe even not removable) after we fix the code to correctly use UTF-7. David, Possibly you can avoid converting the imap code to use pruUnichar (UCS-2 Unicode). If you convert to UTF-8 instead of 8-bit ASCII, the imap code may not have to change since both are null-terminated byte streams. When you talk to other code, you'll need to convert from UTF-8 to pruUnichar instead of just casting up ot 16-bit quanities. This approach might be much easier to implement...
Let me update the status with 1/27/2000 Win32 M14 build. 1. Display of existing JPN folder names --> displays only as dots. 2, Access to existing JPN folder names --> not successful. Cannot display msgs in it. 3. Creation of JPN folder names --> not accepted by the server as we seem to be sending invalid characters and thus fails to create a folder. Note: Latin 1 accented folders are accessible.
Putting on PDT+ radar for beta1.
I really don't know how long this is going to take. Converting the imap code to use unicode would be the wrong thing to do - the conversion has to happen inside nsImapMailFolder - the imap protocol doesn't accept unicode characters.
Whiteboard: [PDT+] → [PDT+] ETA 2/15
OK, I've made a pass at setting the unicode name of a folder based on the utf-7 name as returned by the imap server. I'd appreciate any feedback you can give on whether it helps. I haven't done anything about folder creation.
Is this in tomorrow's build? If so, I'll take a look.
yes, it will be in tomorrow's build.
Looks good. Now I can see Japanese folder names as well as Latin 1 names. However, I cannot access these folders. I'm told that the server responded that such a folder does not exist. You say that we cannot create such folders yet and so I assume that fixing that will take care of the viewing content problem. Right?
I'm glad you can see them,anyway. No, it sounds like some other problem. If you could set up these folders in a test account I could get access to, then I could try to debug it. Thanks for your help!
I've set up an internal test account with 2 Japanese-named folders and 1 Latin 1 name folder. All three folders have 5 Intl Smoketest msgs. At present you can only see the content of the Latin 1 folder named "Be^ta", not the content of the 2 Japanese folders. Will send a login info by mail.
OK, I can see the folder names and read the messages. Marking fixed. Thanks for all the help!

David, should we create a new bug for creating non-ASCII named folder on IMAP servers?
I might have fixed that one too - try it again, if you would.
actually, all the folder creation routines in the system take const char *, so this can't work. It's not just the imap routines, but I'll try to fix everybody to take PRUnichars - it'll take a while, though. I'll open a new bug for that.
Yes. I tried 2/5/2000 Win32 build and was able to display the msgs in the Japanese folders but not create a new one -- an illegal character warning was issued. I'll verify this one again on Monday's build.
**Checked with 2/7/2000 Win32 build ** Japanese folder names on IMAP servers display correctly. Latin 1 names continue to be displayed correctly. I'm going to mark this verified/fixed. ji, please re-confirm with Linux build and if you find a problem there, please re-open this bug.
