[Python] while True と while 1

while True と while 1 では結構性能が違う。

Python 2.7.1 on win32
>>> import timeit
>>>
>>> stmt1 = """
... i = 0
... while True:
...     i += 1
...     if i > 100:
...             break
... """
>>> stmt2 = """
... i = 0
... while 1:
...     i += 1
...     if i > 100:
...             break
... """
>>> t1 = timeit.Timer(stmt = stmt1)
>>> t2 = timeit.Timer(stmt = stmt2)
>>> t1.timeit()
8.104886514906184
>>> t2.timeit()
5.19364556109781
>>>

while 1 のほうが速い。

[CherryPy] Hello world

Solaris11 ExpressのCherryPy 3.1.2でhello world。

#!/usr/bin/env python
# coding: utf-8
import cherrypy

class Root:
        @cherrypy.expose
        def index(self):
                return "Hello, world"

# IN6ADDR_ANY(::) で LISTEN
cherrypy.server.socket_host = "::"
cherrypy.quickstart(Root())

ほぉほぉ。

[Python, Solaris] pynvpairにnvlistのイテレータ追加

pynvpairにnvlist_next_nvpair()を使ったイテレータを追加したのでforでまわせるようになった。

nvlist_print()の代替実装例。

def nvlist_print(nvlist, indent = 0):
    for type, name, value in nvlist:
        if not isinstance(value, list):
            if type == DATA_TYPE_NVLIST:
                print "%s%s:" % (" " * indent, name)
                nvlist_print(value, indent + 4)
            else:
                print "%s%s: %s" % (" " * indent, name, value)
        else:
            print "%s%s:" % (" " * indent, name)
            indent2 = indent + 4
            for i, v in enumerate(value):
                if type == DATA_TYPE_NVLIST_ARRAY:
                    print "%s[%d]:" % (" " * indent2, i)
                    nvlist_print(v, indent2 + 4)
                else:
                    print "%s[%d]: %s" % (" " * indent2, i, v)

[Python, Solaris] libnvpairのpythonインタフェース

OpenSolaris動作するlibnvpairのpythonインタフェース。
b134で動作確認。

こんな感じ。
>>> from pynvpair import *
>>>
>>> a = nvlist()
>>> a.add(DATA_TYPE_UINT64_ARRAY, "test", (0, 100, 12345))
>>> a.dump()
test[0]: 0
test[1]: 100
test[2]: 12345
>>> a.lookup(DATA_TYPE_UINT64_ARRAY, "test")
[0L, 100L, 12345L]
>>> 
何かに使えそう。

[Python] 例外処理とif...elseのコスト

例えば、あるループ中にあるシーケンスの要素を参照するとき。
for i in range(10):
    value = a[i]
これだと、インデックスiが有効かどうかわからないのでどうにかしたい。

(例1)
とりあえず長さをチェックして参照する。
for i in range(10):
    if i < len(a):
        value = a[i]
これはループで毎回len(a)するのでいかにも遅そう。

(例2)
シーケンスの長さが変わらないのであればループの前にあらかじめ長さをとっておこう。
alen = len(a)
for i in range(10):
    if i < alen:
        value = a[i]

(例3)
とりあえず参照して例外を拾おう。
for i in range(10):
    try:
        value = a[i]
    except IndexError:
        pass

どれを使うのがよさげなのか計ってみよう。

テスト用スクリプト
#!/usr/bin/env python
import timeit

# インデックスiが範囲内の場合のセットアップ
setup1 = """
a = [ 1, 2, 3 ]
alen = len(a)
i = 1
"""

# インデックスiが範囲外の場合のセットアップ
setup2 = """
a = [ 1, 2, 3 ]
alen = len(a)
i = 5
"""

# 例1用ステートメント
stmt1 = """
if i < len(a):
    a[i]
else:
    pass
"""

# 例2用ステートメント
stmt2 = """
if i < alen:
    a[i]
else:
    pass
"""

# 例3用ステートメント
stmt3 = """
try:
    a[i]
except IndexError:
    pass
"""

print timeit.Timer(setup = setup1, stmt = stmt1).timeit()
print timeit.Timer(setup = setup1, stmt = stmt2).timeit()
print timeit.Timer(setup = setup1, stmt = stmt3).timeit()
print timeit.Timer(setup = setup2, stmt = stmt1).timeit()
print timeit.Timer(setup = setup2, stmt = stmt2).timeit()
print timeit.Timer(setup = setup2, stmt = stmt3).timeit()
実行結果 
# インデックスが範囲内
0.361014127731 # 例1
0.125293016434 # 例2
0.128052949905 # 例3
# インデックスが範囲外
0.284233808517 # 例1
0.101886034012 # 例2
1.82788801193  # 例3

例外処理で実装した場合(例3)のインデックスが範囲外になる時が飛びぬけて遅い。
つまり、例外発生のコストは結構大きい。
例外発生が頻繁に発生することが予測される場合、if...elseで簡単に
代替できるのであればif...elseを使ったほうが高速。

[expect] spawnしたプロセスの終了ステータスを得る

spawnしたプロセスの終了ステータスを得たいことがある。
この場合はwaitでプロセスの終了を待つと、結果が返ってくる。
結果はリストになっていて3番目(インデックス2)が-1の場合は
OSエラー、0の場合は4番目(インデックス3)にswawnしたプロセスの
終了ステータスが入っている。

スクリプトの例。読み取り権のないファイルをcatして終了ステータスを得る。
spawn cat /etc/shadow
expect eof
catch wait result
set OS_ERROR [ lindex $result 2 ]
if { $OS_ERROR == -1 } {
        puts "Fail to exec"
        exit 127
}
set STATUS [ lindex $result 3 ]
exit $STATUS
スクリプト自体をcatの終了ステータスで終了する。


実行結果
$ expect test.expect
spawn cat /etc/shadow
cat: /etc/shadow: Permission denied
$ echo $?
1
きちんと1が返っている。

expectはTcl言語の文法を知らないとちょっと戸惑う。
man expectでもよくわからないと思うことは実はTcl言語の文法だったり。
