Code Audit, OSC, a DirectFB ML post

上司の方にマージの為に預けておいたBCBなブツを弄った．
うへ，日付毎のスナップショットしかないんですから，
ChangeLog一行でソースコードにコメントも碌に無しで，
変更なんてやらないで．．．御願いします．．． :(
早いトコ，何か適当なSCMを使って貰わんと
会社中unmaintainableなコードだらけになる悪寒．
[I had poking the BCB ones which was maintained my boss.
Umm, ATM, we have only daily snapshots though,
but it was poked w/ only 1 line ChangeLog w/o any comments.
Blah, no more crazy change w/o documentation if it's ovbious...
Please, I have not so quite coding skill... :(
Hmm, we definitely needs to use SCM.
Otherwise, we'll choke ourself by unmaintain code stuffs.]

で，Linuxの方の旧実装の為に書かれたコードも見てみた．
なかなかイイ感じにグローバル変数やらシグナルハンドラやら
マジックナンバーやらがそこかしこに散らばっている．
動作実績はあるけど，何か気に食わない．．． :(
[Then, I also do audit some previous Linux stuffs for its project.
Hmm, some delicous global vars are, scattered signal handlers are,
nice magic numbers are stuffed.
It jusr works, but well, umm a bit of subtle thigy... :(]

Gentoo JP misc MLでOSC 2006 Tokyo/Fallについてのスレッドが動く．
10月末だったら今の仕事は終わってるだろうケド，
何か発表するほどエラい訳でもない．
非x86なGentooは沢山有るケド，
会場までSPARCとかAlphaを持って行くのは
良く良く考えてみたら，何気に死ねそうだ．
カンバッジを箱買いして，
ユーザー（候補？）に配る（タダ？）くらいは出来そう．
しかし，Kalinも仕事でハマっていたとは． :P
[A thread of Gentoo JP misc ML about OSC 2006 Tokyo/Fall moves.
When it's at the end of Oct, the project would be finished, though.
I'm not official dev, so I have no right to mention about Gentoo thigs.
Of cource, I have many junky non-x86 boxes,
but Alpha/SPARC boxes are not potable ones,
and it's hard to bring/bring back it.
Hmm, sonds like to get Gentoo bottons distrubuted
(as fee free?) some users (or candidates?) is not quite difficult, though.
BTW, it's not quite bad to hear Kalin was choked his job. :P]

或るGentooユーザーのDirectFB users MLでの投稿．
微妙にupstreamのMLで話す内容でもないので，
「公式のEbuildを使えば？」
みたいな返事を書いたら，
「公式のEbuildだと，オラのMatroxカードが動かんのじゃー」
みたいな返信を直に貰う．
で，取り敢えず，
「RiceなCFLAGSとかを止めて，
巧く行く野良ビルド時のコンフィグ結果を確認した上で
USE flagsをきちんと設定して，且つ必要な設定ファイルを書いて，
それでもダメならGentooのBugzillaに貼っといて．
そしたら，もう少しマトモに相手をしてあげるよ」
みたいな返信しておいた． :P
[A post of DirectFB users ML from a Gentoo user is.
It sounds like not suit upstream ML, so I've replayed like
"Why didn't you use official ebuild?"
Then, he directly replayed me like,
"The reason is my Matrox card didn't get woking w/ gentoo's."
Like someone always said,
"make it no crazy CFLAGS, check the difference of config result of
strayed build and getoo's to set sane USE flags or so,
write config files w/ reading fine manuals.
Then, if it still didn't work, file it Gentoo's bugzie.
I'm OK to hang on. :P"]

Memo4JunkyPCMCIA

んー，これかな．．．？
取り敢えず，メモ．
[Well, this?
Isn't it worth to note, or...]

眠い，おやすみ．．．

Memo4OldRedHat, kde-base/kttsd

Geodeの方が例のPCMCIA関係でハマりっぱなしなので，
現在の状況と問題点をまとめて上司様々にメールを投げておいた．
で，過去のRedHat9 kernel 2.4.x時のセットアップのメモを読んでみた．
予想はしていたけれど，rpm直叩きの上に，一部野良ビルドかよ．．． :P
明日からは，現実逃避でコーディングを再開予定也．
[Hmm, Geode still sucks PCMCIA stuffs.
I've summrized about it, and emailed my bosses.
Then, I've skimed old setup memo for RedHat9 w/ kernel 2.4.x, though.
Bleh, that's really horrible combo of "direct rpm command" and
"straied configure && make && make install"...
But, that's I expected, though. :P
Tomorrow, I'll restart my coding instead of poking that junky Geode.]

で，全然関係無いIRCチャンネルで
kde-base/kttsdの日本語関連の開発状況(?)を訊かれた．
日本語が読めないから，その辺りの情報の探し様が無いのだとか何とか．
適当にgoogle.co.jpで検索してみるが，mirrorのindexとか，
2004年とか2005年頃の関係者と思しき人の日記くらいしか引っかからない．
正直に言うと，自分は使ってないから構わんのだけど，
昔，KDEって日本語ローケルサポートがダメダメでリリースから外されなかったけ？
あー，知らんぜー． :P
[BTW,
I was asked about kde-base/kttsd development status of japanese support.
He said that he couldn't understand japanese text, so couldn't find any info.
I've skimed by uisng google.co.jp, but it shows me only mirror index,
or old jap dev diary's entries or so.
TTTT, I havo no KDE stuff, thus it's no matter for me.
But, when KDE had many b0rked japanese support,
the upstream abandoned to release w/ japanese support, IIRC.
Well, please no blame me, it's not my fault, duh? :P]

IRQ confliction hell

Kernelの.configを調整しながらBIOSを調整した．
が，BIOSのメモリチェックの段階で256MBなブツなのに
128MBしかBIOSが認識していない事に気付く．
Frame Bufferを整理したら，gxfbは動くがgx1fbは動かないっぽい．
前者は(Experimental)で，後者は(Very Experimental)らしい．
更に，CFのmulti mode by defaultは動いたが，
use DMA when availableだと動かないっぽい．
[Hmm, I was poking kernel's .config and BIOS stuffs.
Well, that dumb BIOS sucks because it couldn't do sane mem checking,
I realized it is 256MB, but only available 128MB, though.
And then, (Experimental) gxfb just works, but (Very Experimental) gx1fb
doesn't workd, WTF...
CF can use multi mode by default, but couldn't use DMA when available, NFC...]

で，802.11a/b/gなWireless LANカードを突っ込んだ所，
USB1.1 OHCIなブツとPCMCIAカードバスのIRQがconflictしてる．．． :(
TIのPCI1410と言う16bit legacyなchipの所為っぽい．
sys-apps/pcmciautilsじゃダメかも．．．
うーん，sys-apps/pcmcia-csかなー？
いやいやsys-apps/pcmcia-cs-cisも使うのかー？
それともsys-apps/pcmcia-cs-modulesかー？
はたまたsys-apps/pcmcia-pnp-toolsかー？
コイツが動いてくれないと，ひじょーにマズいぜよ． :P
[Then, when I stab 802.11a/b/g wireless LAN card,
USB1.1 OHCI anf PCMCIA card bus got IRQ confliction... :(
TI PCI1410, 16bit legacy chipe needs to die.
PCMCIA stuffs make me mess, there're sys-apps/pcmciautils,
sys-apps/pcmcia-cs, sys-apps/pcmcia-cs-cis, sys-apps/pcmcia-cs-modules,
sys-apps/pcmcia-pnp-tools.
Well, I wouldn't be shot by my bosses, though. :P]

UTF8+IPAPGothic+GMail = MojiBake

shindoさんの言っていたGMailの怪現象が再現したので，
記念にスクリーンショット． :P
L -> *になってる，v -> Tにもなるらしい．
[Like shindo-san said, I reproduced MojiBake when using UTF8 and IPAPGothic.
Here's a screen shot of L -> *.
And, v -> T could be.]

Geode GX1 boot log or so

こんな感じになった．
まだ幾つか問題が有るケド，取り敢えずserial consoleとdropbear SSHが動いたので，
残っている別の作業をせねば．
以下，メモ．
1) kernelの.configを調整していない所為で，要らないモノが結構有る．
2) その所為でframbufferがboot中にどこかに逝って仕舞うし，CFのDMAが効かない．
3) udevを/dev/console, /dev/nullだけから動かしているのでbootが激しく遅い．
4) rootfsの大きさが100MB以上．
[K, it just works.
Some unstisfied thigies even are, though.
Serial cosole works, dropbear SSH works... So, I must do other codings.
Some memo are on the below.
1) Kernel's .config aren't sanitized, many unneeded config options are.
2) Due to 1), framebuffer got corrupted and CF's DMA are disabled ATM.
3) Using udev w/ only /dev/{console,null}. So, it makes boot time slowly.
4) Size of rootfs exceeded 100MB, it's too huge as embedded rootfs.]

Poking Geode, no virtual/yacc ATM

例のEmbedded uClibc GentooなGeodeは一応bootした．
シリアルコンソールとかFrame BufferとかdropbearなSSHとか，
まだ/etc以下の調整が必要也．
man, info, doc抜きで，展開したkernelのソース，ebuildのツリー，
Portageのキャッシュをお掃除して，self update/debugが最低限可能な様に
toolchainとGentooなバイナリを残した状態で大体，300MB弱になった．
runtime環境で必要十分な状態．．．
詰まり，ヘッダファイルや普段使わないライブラリやら
バイナリやらを整理すれば，100MB以下にする事も出来るケド，
わざわざbinpkgを作るのは性に合わないので，
ベースにするrootfsで無理なダイエットはしないつもり． :)
[The Geode one tentative boots w/ embedded uClibc Gentoo.
But, it needs more pokings for serial console, frame buffer, dropbear SSH or so
which are configured by /etc files.
No man/info/doc stuffs,
cleaning extracted kernel sources/ebuild tree/Portage cache,
to make it keep to update/debug itself, leaving tool chain and gentoo's utils.
Now, its size is about 300MB or so.
Of cource, really iif runtime env which is not madantory ton of headers,
unneeded libs, not normally bins.
And yes, it's not quiet difficult to reduce the size less than 100MB.
But to make binpkg myself is not my taste, duh.
So hardly diet for my base rootfs isn't sane, IMHO. :)]

で，sys-apps/pcmcia-csやらsys-apps/pcmciautilsを弄っていたら，
dev-utils/yaccとsys-devel/bisonでcollision-protectにハマる．
profileのsystemで入ってくるsys-devel/bisonを-yオプション付きで使えば，
YACC compatな動作をするので，dev-util/yaccを入れる必要は無いハズ．
今の所，virtual/yaccが無い所為でdev-util/yaccに直接DEPENDしてる． :(
#gentoo-dev-help@FreeNode.netで訊いてみると，
YACC compatなブツは四つ以上有るらしい．
後でbugzillaに貼っとくか，メモメモ． :P
[BTW, when poking sys-apps/pcmcia-cs and sys-apps/pcmciautils,
dev-util/yacc and sys-devel/bison have file collision for these bad dependencies.
These PCMCIA packages have dev-util/yacc as directly DEPEND atom,
but sys-devel/bison was emerged as one of system profle stuffs,
and then "bison -y" is YACC compat, though.
So, it's the fault of no virtual/yacc ATM.
According to #gentoo-dev-help guy,
4 or more YACC compat ones in official ebuild tree.
Hmm, this memo will remind me to need to file virtual/yacc RFC to bugzie. :P]

uClibc stage tarballs, ppc Mac mini

例の仕事で，NS Geode GX1 300MHzなBox PCの為に，
i586-*-linux-uclibc Embedded Gentooなルートファイルイメージを
作ってムニャヘニャしようとしたら，公式（？）に配布しているっぽい
tar玉が古過ぎる事に気付く．
[I've poked NS geode GX1 300MHz,
to create i586-*-linux-uclibc Embedded Gentoo rootfs.
But, umm, I realized official/experimental tarballs are
pretty old, though.]

0) stage3-x86-uclibc-2005.0.tar.bz2を展開して，
1) sys-apps/portageをアップデートして，
2) /etc/make.confと/var/run/bootstrap-progressをムニャヘニャして，
3) /usr/portage/scripts/bootstrap.sh && emerge -e systemを実行．
多分，古いtoolchainとかのゴミが残るので，お掃除しなきゃなー． :(
[0) Extract stage3-x86-uclibc-2005.0.tar.bz2,
1) Update sys-apps/portage,
2) Poking /etc/make.conf and /var/run/bootstrap-progress,
3) Do /usr/portage/scripts/bootstrap.sh && emerge -e system.
Hmm, some craps even are, need to purge it, though. :(]

で，念願のppc Mac miniを手に入れた．
メモリは512MBだけど，PowerPC G4 1.5GHzで
ATI Radeon 9200 64MBなブツが¥60k弱．
コイツはAthlon Thunderbird 1.2GHzでクタビれてきた奴の代わりにしようっと．
あ，でもdev-util/mercurialなレポジトリ用のサーバにもしたいなー． :)
[BTW, I got a ppc Mac mini.
512MB memory, PowerPC G4 1.5GHz, ATI Radeon 9200 64MB...
It was costed about ¥60k == $550.
Hmm, which is better choice use it as replacement of Athlon
Thunderbird 1.2GHz desktop or new dev-util/mercurial repo serv? :)]

FIX: silly typo on title (taralls -> tarballs)

やっぱメインメモリ共有なチップはダメだな． :P

    Hi all
8/15 18:18:14 Sante
    i am working in a fakeroot environment trying to compile something
    video related (NMM)
8/15 18:18:20 Sante
    it says im missing a library called ltdl
8/15 18:18:25 Sante
     so i installed libtool-1.5.22
8/15 18:18:32 Sante
    i am using a powerpc architecture so when i run ./configure i use
    CC=ppc-gcc CXX=ppc-g++ --arch=ppc
8/15 18:18:38 Sante
    then run make and make install
8/15 18:18:42 Sante
    and it appears fine
8/15 18:18:48 Sante
    but when i run file library it says Intel 80386

    mmp wonders how could be ppc files linked into 386 executable

    hang on
8/15 18:28:01 Sante
    the build directory, u mean the directory in which the files are
    installed?
8/15 18:28:16 Sante
    ie usr/local/lib?

    Hi, yesterday I had a problem and until today I didn't solve
    it. When trying to bootstrap stage1 uclibc I get the error right
    at the strat of the process: * Executing: emerge --oneshot -p -v
    virtual/os-headers sys-apps/texinfo sys-devel/binutils sys-devel/gcc
    virtual/libc virtual/baselayout sys-libs/zlib ------ These are the
    packages that I would merge, in order: ----- Calculating dependencies
    |!!! Cannot resolve a virtual p
8/15 18:32:16 mmp
    Sante: where you build the sources, where are the object files
8/15 18:32:36 mmp
    Sorry that I did not write it more clear...
8/15 18:35:32 Sante
    the object file is POWERPC
8/15 18:37:48 jooopy
    is the http://www.bulah.com/embedded-guide.html should work? Are
    ppl here have experience with it?
8/15 18:37:54 hiyuh
    Sante: to use more sane CHOST/CTARGET/CBUILD is worth to consider,
    though.
8/15 18:38:06 hiyuh
    Sante: and then,  -I$target_incdir -L$taregt_libdir could help. but
    some apps'/libs' configure script sucks x-compile.
8/15 18:38:24 jooopy
    I also have something I don't understand
8/15 18:38:41 *
    theBear doesn't understand many things
8/15 18:39:12 jooopy
    If I run on the host system : ROOT="/tmp/minime" USE="make-symlinks"
    emerge uclibc busybox baselayout-lite dropbear
8/15 18:39:36 jooopy
    This should make an image, or I need more steps?
8/15 18:40:09 hiyuh
    jooopy: nope, virtual/* will be provided by installed packages,
    IIRC. don't emerge explicitly these virutal stuffs.
8/15 18:40:14 Sante
    ok
8/15 18:40:50 Sante
    what do u mean by CHOST/CTARTGET/CBUILD
8/15 18:41:22 jooopy
    hiyuh:  How do I know what are the virtual stuffs?
8/15 18:41:38 theBear
    the category is virtual/
8/15 18:41:39 jooopy
    hiyuh: I just ran ./bootstrap
8/15 18:42:34 jooopy
    hiyuh: should I block libiconv in /etc/portage/packages.mask ?
8/15 18:43:12 hiyuh
    jooopy: the sources always with you. :P
8/15 18:43:43 Sante
    hiyuh: i dont understand the CHOST stuff, and what u wrote next
8/15 18:44:44 hiyuh
    jooopy: sound like you're trying to build from stage1?
8/15 18:45:26 jooopy
    hiyuh: yep, but I don't realy have to. I just follow
    http://www.bulah.com/embeddedgentoo.html
8/15 18:45:38 jooopy
    hiyuh: Should I start from stage 3?
8/15 18:46:17 jooopy
    hiyuh: can you refer me to a good howto ?
8/15 18:47:54 hiyuh
    jooopy: first of all, see the
    topic. http://arcanux.org/guidexml/cross-development.html
8/15 18:48:30 jooopy
    ok
8/15 18:49:25 hiyuh
    Sante: you should read env-ver section in this documents.
8/15 18:49:48 Sante
    ok
8/15 18:49:55 Sante
    ehmm which documents?
8/15 18:50:00 Sante
    http://arcanux.org/guidexml/cross-development.html ?
8/15 18:50:05 hiyuh
    yep
8/15 18:50:25 Sante
    im not using gentoo btw
8/15 18:50:30 Sante
    but ill have a look
8/15 18:53:20 hiyuh
    Sante: except some commands in this document, these info are common
    knowledge of x-development, IMHO.
8/15 18:54:49 Sante
    ok
8/15 18:55:09 Sante
    i still dont really get my problem, i mean it appears to be compiling
    correctly
8/15 18:55:26 Sante
    can i show u the ./config and make dumps ? maybe u can help me out
8/15 18:57:37 hiyuh
    Sante: of cource, you can show us. but I cann't bet you expext. :P
8/15 18:58:08 hiyuh
    s/expext/expect/
8/15 18:58:12 Sante
    hehe
8/15 18:59:05 Sante
    http://pastebin.ca/132432
8/15 18:59:08 Sante
    thats configure
8/15 18:59:39 Sante
    and make
8/15 18:59:40 Sante
    http://pastebin.ca/132433
8/15 19:04:15 Sante
    any idea ?
8/15 19:08:07 hiyuh
    Sante: hmm? it looks libtool installing is ok. then, you mean you
    couldn't link target libs?
8/15 19:15:35 Sante
    i mean
8/15 19:15:49 Sante
    when i try to compile my app it says ltdl not found
8/15 19:21:46 hiyuh
    hmm? so, ltdl is "libltdl.{a,so}" as your target lib?
8/15 19:29:31 hiyuh
    Sante: FYI, this is "locate ltdl" result of my ~ppc gentoo (but
    notice, only self compilation tools was installed).
8/15 19:30:02 hiyuh
    http://rafb.net/paste/results/OmlsA693.html
8/15 19:30:25 hiyuh
    So, if your apps need to link libltdl.{so,a}, you should do like that.
8/15 19:30:38 hiyuh
    1) compile it with "-I$inc_dir", $inc_dir is where target's ltdl.h is.
8/15 19:30:41 hiyuh
    2) link it with "-L$lib_dir -lltdl", $lib_dir is where libltdl.{so,a}
    are.
8/15 19:31:24 hiyuh
    maybe, you should check step 2), IMHO.
8/15 19:48:44 Sante
    wait
8/15 19:48:56 Sante
    at what step do I link with -L$lib_dir -lltdl"
8/15 19:48:57 Sante
    ?
8/15 19:49:23 Sante
    and i dont have libltdl.so
8/15 19:49:49 Sante
    only .a
8/15 19:50:00 Sante
    when i compile with standard gcc i get the .so aswell
8/15 19:50:07 Sante
    hiyuh: is that normal ?
8/15 20:33:35 hiyuh
    Sante: *.a is an "ar archive" for static link. *.so is "shared object"
    for dynamic link... if you specfied to build only "ar archive"
    or your x-compiler can only build static ones, it is normal.
8/15 20:34:27 Sante
    ah ok
8/15 20:34:37 Sante
    then my compiler can only do static ones
8/15 20:35:05 Sante
    but why does my app complain that ltdl is not installed then ?
8/15 20:40:22 hiyuh
    Sante: nope, it may be not your apps' fault. to link is to working
    of linker as a part of toolchain...
8/15 20:40:35 Sante
    hmm ok
8/15 20:40:37 hiyuh
    in static link case, libltdl.a should be linked when it was build,
    and it's in $lib_dir was specfied -L option. and then you need
    -static as well.
8/15 20:40:50 Sante
    hang on
8/15 20:40:52 Sante
    where do i do this ?
8/15 20:42:47 hiyuh
    sane fixing is poking *.{in,am,ac} or so. otherwise, poking Makefile
    or manually link it where it failed, IMHO.
8/15 20:43:27 Mimil
    hi all
8/15 20:44:07 Sante
    ok
8/15 20:44:08 Sante

8/14 18:47:34 jcath
    it publishs some very good books and magazines

8/14 19:00:16 jcath
    is the magazine"design wave" expensive ?
8/14 19:03:55 hiyuh
    bit of expensive WRT its thickness. but sometime it comes with nice
    supplement like sample board (a tiny CPU and FPGA or so).
うーん，その手の雑誌は海の向こうには無いのかな？
[Well, any pub like CQ doesn't be at overseas?]

KandR[2].Appendix.interest++;

C++が気に入らなくて，現実逃避でK&R 第二版を読み直してたら，
何気に付録が面白い事に気付く．
で，bison/flex (yacc/lex)が使いたくなってきた．
無謀にも少しモニョってみる．．．つもり． :P
[C++ seems stab me.
So, I did cop-out w/ rereading K&R SE.
Then, I realized its appendix is bit of interesting.
It makes me proceed bison/flex (yacc/lex) way.

memo of autoconf-2.60 bugs.

autoconf-2.60関連のメモ．
  • */*-svnなパッケージとかでautogen.shを使っているブツ．
    inherit autotoolsでeautoreconfを使って，autogen.shは使わない．

  • ${S}/m4な感じでm4マクロが分かれているブツ．
    inherit autoconfでAT_M4DIR=${S}/m4 eautoreconf．

[A memo of autoconf-2.60 stupidness...
  • kinda */*-svn packages or so which uses autogen.sh.
    inherit autotools and use eautoreconf, instead of autogen.sh.

  • has ${S}/m4 as modulized m4 macros.
    inherit autoconf and use AT_M4DIR=${S}/m4 eautoreconf.
]

と言う訳で，cjkなエラい人様々，
このブツがautoconf-2.60で"プチ"壊れていますのでヨロシク． :)
[@cjk devs, please fix this silly autoconf-2.60 bugs. :)]

autoconf_2_60.karma--; or so

BCBでムニャヘニャしている隣で，
Gentoo on PowerBookのemerge -e worldを走らせていた．
で，sys-devel/autoconf-2.60が幾つかのebuildでハマる原因に
なっているっぽい事に気付く．
[Still poking BCB ones.
Beside that, my PB heats to emerge -e world.
Then, seems sys-devel/autoconf-2.60 makes some
b0rked it.]

8/03 12:07:09 dragonheart
    hiyuh: thanks for the reminder (-commits)
8/03 12:07:19 dragonheart
    hiyuh: how has it broken your life?
8/03 12:44:41 hiyuh
    dragonheart: I guess sort of that. but half of
    my breakages is in my own ebuilds (unofficial ones).
8/03 12:44:50 hiyuh
    I'll try to figure each casus out,
    then poke upstream or bugzie.
と言う事で，もう少し弄ってみる事にする． :)
[K, need a bit of to poke it. :)]

で，例のモノはまだ色々dead lockするパターンが．．．
(Snippet log of #ep93xx@FreeNode.net)
8/03 17:20:30 *
    hiyuh got some dead lockings in his stupid threads
    progs.

hg2svn.tailor, BCB.PITA++;

dev-util/tailor．．．使い方がヨクワカラン． :P
subversionのレポジトリ構成を理解していない所為だなー．
多分，どこか間違ってるハズ．
[dev-util/tailor... it makes me messy. :P
Well, that must depend on my ignorance about
subversion repository structure and scheme or so.
Some bad things are...]
[DEFAULT]

例のBCBなプログラム，なめてかかっていたら色々面倒な事やっているっぽい．
「制限時間付き待ち行列の各要素に対する運用上問題の無いハッシュ関数」？
グローバル変数のカウンタを回しつつ，似非mutexでロック．
現場でハッシュの値域が足りなければ，
カウンタの上限を上げてcut and tryって，美しくねぇー． :P
[The stupid BCP progs, that makes me really cofuse.
"An operational well-evaluated hash function
for event queuing which has a time limimt"？
Its implementation is,
* Count up crappy global var with a defined maximum value.
* Lock it with dirty mutexing to prevant accessing conflicts.
* If the rage hash value was too narrow, redefine its maxmum value.
For define that maximum value, to cut and try is the way to evaluation.
Bleh, it makes me.code.karma--; :P]

あと，双方向リストのpush/pull/findをdead-lockしない様にに実装せねば．．．
やべー，納期がー，あー，納期がー． :P
[And then, it required no dead-locking push/pull/find
functionalities for bi-directional list...
Oh, well, there're some dead-locks, here's some dead-lines. :P]
