So this only happens with scim-tables IMEs (factories)? ----- Additional Comments From toshiona.com 2006-05-17 02:56 EDT ------- I found that the problem occurred when both "scim-talbes-chinese" and "scim- chewing" were installed. (This is the default configuration of Fedora Core 5 for Chinese.) If scim-chewing was uninstalled, I didn't seen the problem. It seems the problem happens when the input mode is switched between scim- tables-chinese's one and scim-chewing's one. But, I'm not sure which component has cause. ----- Additional Comments From shoji.com 2006-06-20 21:45 EDT ------- I could reproduce the problem. If you switch IMs rapidly, the problem seems to be occured easier. According to "SCIM" related process status, one scim backend process (IM- Engine <--> socket frontend) is killed. <Before problem> [shoji@localhost ~]$ ps ax | fgrep sci 3380 ?

Patch.
According to valgrind log files, some uninitialized values were used in if
statements of the scim-chewing code.
Please find the attached patch to initialize private members of

Sugiyama-san,
I tried the recreate scenario more than 20 times with your patch, and wasn't
able to recreate this problem. It can say your fix is working.
Thank you!
The function is ChewingIMEngineInstance::ChewingIMEngineInstance. Patch has been added and build in devel for RAWHIDE. Tested the bug on Simplified and Traditional Chinese with Cangjie method.
Result : 1. Pressing a three times, without giving space (aaa) showing 3 char
different chinese char for each key press. Chiness characters are
appearing each time. No ASCII char showing.
2. If type "as" then a candidate window appearing with 2 chars 1 & 2.
If then press 1, the corresponding char is not entering. it is looking like
"as1" Want to mention that, the candidate window appearing after pressing 'a'
and still present on the screen after pressing "s" also. Is it the right
behavior? please see the attachment.
Tested on environments and package versions :
scim-pinyin-0.5.91-5
scim-chewing-0.3.1-1
scim-devel-1.4.4-21
scim-tables-chinese-0.5.6-5
scim-hangul-0.2.2-4.fc6
scim-tables-0.5.6-5
scim-1.4.4-21
scim-anthy-1.0.0-2.fc6
scim-libs-1.4.4-21
scim-qtimm-0.9.4-4
scim-libs-1.4.4-17
scim-m17n-0.2.0-3
And O.S. version in which tested is Fedora Core release 5.89 (Rawhide) - i386.

See if any more screenshot needed. please inform.
Fix is in scim-chewing-0.3.1-2! (Darshan, please mention the package ver-rel next time.) ----- Additional Comments From toshiona.com 2006-07-02 21:56 EDT ------- The behaviors you attached are correct. If this problem occurs, no Chinese character nor alphabet with underline is shown. As we found, the problem intermittently occurs when input mode switched between "scim-talbes-chinese" and "scim-chewing". result is same as the result written in the comment no. - 12. Version tested for the component : scim-chewing-0.3.1-2.1 scim-qtimm-0.9.4-5 scim-pinyin-0.5.91-11.3.fc6 scim-bridge-gtkimm-0.2.6-1.fc6 scim-fcitx-3.1.1-5.fc6 scim-chinese-standard-0.0.2-3.fc6 scim-bridge-0.2.6-1.fc6 scim-input-pad-0.1.1-4.fc6 scim-libs-1.4.4-25.fc6 scim-devel-1.4.4-25.fc6 scim-fcitx-tools-3.1.1-5.fc6 scim-m17n-0.2.0-5.fc6 scim-doc-1.4.4-25.fc6 scim-tables-0.5.6-7 scim-tables-chinese-0.5.6-7 scim-skk-0.5.2-7.fc6 scim-tables-additional-0.5.6-7 Patch was included in -2 but not applied...

spec file of above patch
The patch is not applicable anymore. The expressions and variables in the patch are not used in recent version of scim & scim-chewing. ----- After I tried to reproduce the bug with the latest devel versions: scim-chewing-0.3.1-2.1 scim-devel-1.4.4-31.fc6 scim-debuginfo-1.4.4-31.fc6 scim-1.4.4-31.fc6 scim-tables-chinese-0.5.6-7 scim-tables-0.5.6-7 scim-chewing-debuginfo-0.3.1-2.1 scim-libs-1.4.4-31.fc6 The bug is either does not exist, or it is even not a bug. ----- The steps I reproduce the bug: 1. Alt-F2 -> input "gedit" -> gedit started, click on gedit window to focus. 2. Ctrl-space to turn on scim. 3. Ctrl-shifts to change to changjie. 4. input "aaa" and press Space, a character appears on gedit. 5. a character "æ¶" appears on gedit. 6. Ctrl-shift 3 times and scim changes to Canton-HK input method. 7. input "aa" and candidates come up, press "1" to let "å" appears on gedit. 8. Ctrl-shift 2 times and scim changes to chewing input method. 9. input "ma" and candidates come up, press "1" then enter to let "å" appears on gedit. 10. Ctrl-space to change scim back to english input mode. Repeated above steps but personally I reckon there is no problems found regarding the mentioned behavior problems of scim. ----- FYI, there are differences among the chinese imput methods, some of them uses space key to select a candidates, some of them uses enter key or number keys instead. Also, inputing "aaa" will not guarantee to match a candidate in certain chinese input methods. If eventually such behavior is defined as a bug, it might be considered as another bug when similar symptoms exists in the recent version. So to summarize: apparently the scim-chewing issue is fixed in scim-chewing-0.3.1 which is in FC development. Presumably the problem still exists in fc5: we should probably consider doing an update to fix that. The original patch by dsantani was supposed to put into FC-5 branch but it was in fact put into devel branch. The patch is only applicable to FC-5 (scim-chewing-0.2.1), which scim-chewing-0.3.1 does not need and also not applicable such patch. Patch has now been relocated properly and in progress of rebuild and test. Created attachment 134420 [details]

I rebuilt and did a basic test. ----- Additional Comments From shoji.com 2006-08-21 06:34 EDT ------- Nakamura-san, Could you kindly double check it with the latest scim RPM packages as attached ? Regards, scim-chewing-0.2.1-5.4.fc5 has been pushed for fc5, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report. ----- Additional Comments From toshiona.com 2006-08-21 23:12 EDT ------- I verified the problem was fixed on scim-chewing-0.2.1-5.4.fc5.i386.rpm in http://download.fedora.redhat.com/pub/fedora/linux/core/updates/5/i386/ Thank you. |
LTC Owner is: dmosby.com LTC Originator is: toshiona.com Problem description: Chinese SCIM InputMethod was down intermittently when input mode was switched. At that time, any key press inputs ASCII character directly, not to Chinese conversion method. We cannot resolve the situation except restarting SCIM. The problem occurs on both Traditional Chinese and Simplified Chinese The problem occurs on the system installed in Chinese as default, and the system added Chinese support after install. When the problem happens, SCIM menu doesn't display some icons; "Switch between English and Chinese", "Switch between Wide and Half-width char", "Switch comma and period style". Hardware Environment Machine type (p650, x235, SF2, etc.): IA32 PC Cpu type (Power4, Power5, IA-64, etc.): Xeon 2.4GHz x2 Is this reproducible? Yes If so, how long does it (did it) take to reproduce it? About 3 minutes. Describe the steps: 1. Install FedoraCore 5 with Traditional Chinese or Add Chinese support. 2. Login X-Window in Traditional Chinese Locale. 3. Open gnome-terminal. 4. Press Ctrl+Space key to activate SCIM. 5. Press Ctrl+Shift to switch to "CangJie" input mode. 6. Input some characters. For example, "aaa" and space 7. Press Ctrl+Shift key several times to switch input mode. => Sometimes, Chinese cannot be input. SCIM is running, but any input was entered as ASCII characters. If the problem didn't occur, please repeat step 5 to 7. Is the system (not just the application) hung? No Did the system produce an OOPS message on the console? No Is the system sitting in a debugger right now? No We can set up the victim system. Please contact me if you need.
