大家好我現在遇到一個小問題

首先就是我的空白鍵是選字鍵

在我「還未輸入任何中文前」，只要按下空白鍵 (似乎就會去試圖想要去選字，然後根本沒有字給他選)

就會使得畫面卡住

以下是我的一些設定

系統 Gentoo

安裝 package: =app-i18n/gcin-2.8.3 USE="filter-nobopomofo gtk3 qt4 -anthy -chewing -chinese-sound"

還有相關設定

這個先移除看看。

移掉 gtk3 qt4 之後還是一樣會卡住
[ebuild R ~] app-i18n/gcin-2.8.3::gentoo-zh USE="filter-nobopomofo -anthy -chewing -chinese-sound -gtk3 -qt4"

可能先只 install gcin 最基本的，create 新的 user account. 從頭開始測才知道問題在哪裡。

這是gentoo在安裝gcin-2.8.3時的設定檔

https://github.com/microcai/gentoo-zh/blob/master/app-i18n/gcin/gcin-2.8.3.ebuild

預設部份只有

--use_i18n=Y --use_tsin=Y  --use_qt3=N

沒有太多複雜的設定

剛剛測試了一下 2.8.0~2.8.3 各個版本

都是用 gentoo portage ebuild 的安裝方式，預設條件都相同(見上篇)

2.8.0 和 2.8.1 不會按空白鍵就卡住

看來是從 2.8.1 → 2.8.2 這次改版引發的問題

是用什麼輸入法？有 diff gcin 2.8.1 2.8.2，看不出問題出在哪裡。

只有詞音輸入法會出現這個問題

我來考古一下，和很不專業的 trace

reproduce steps

1. 環境和上面一樣，gcin 改成用 2.8.5
2. 在 firefox 網址列打「中文字」後，按下 Enter。此時工作列是「詞」詞音狀態，尚未輸入任何字
3. 準備輸入空白，所以按了一下空白鍵，然後就 hang 住

這邊是有用 GCIN_OUTPUT_FILTER 才會進入這段 code，這個 filter 只能用在 filter process 執行然後馬上結束，如果 filter process 一直不結束，就會產生卡住這種情形。我自己沒在用。

這個 filter 有可能造成安全漏洞，未來的版本有可能會內定不開啟，需要使用者自行 compile 打開。

感謝解惑。我現在把注音文的 filter 拿掉，就不會卡住了。
接下來我再來看看，是不是 script file 有權限問題造成卡住，或是其他原因
