php curl タイムアウト動作

コメントを残す

$ uname -r

$ /usr/local/php-5.6.16/bin/php --version
PHP 5.6.16 (cli) (built: Aug 28 2017 06:35:52)

結論

curl のタイムアウト動作に対して、

default_socket_timeout は影響確認できず（ini_set）
max_execution_time は影響確認できず（set_time_limit）
CURLOPT_CONNECTTIMEOUT は作用する（curl_setopt）
CURLOPT_TIMEOUT も作用する（curl_setopt）
CURLOPT_DNS_CACHE_TIMEOUT は影響確認できず（curl_setopt）
デフォルトでは2分強でタイムアウト（カーネル仕様と思われる）

curl_setopt 設定値

CURLOPT_CONNECTTIMEOUT ：接続の試行を待ち続ける秒数。0 は永遠に待ち続けることを意味します。
CURLOPT_TIMEOUT：cURL 関数の実行にかけられる時間の最大値。

curl_errno の戻り値

正常時：CURLE_OK (0)
カーネル側のタイムアウト：CURLE_COULDNT_CONNECT (7)
CURLOPT_CONNECTTIMEOUT / CURLOPT_TIMEOUT：CURLE_OPERATION_TIMEDOUT (28)

カーネル側のタイムアウト動作

$ time /usr/local/php-5.6.16/bin/php curl.php
real    2m7.345s
user    0m0.000s
sys     0m0.012s

$ cat /proc/sys/net/ipv4/tcp_syn_retries

slab増大とcurlのNSS_SDB_USE_CACHE対策の効果確認

コメントを残す

AWS SDKを使用しているとslabが肥大化していく現象

NSS_SDB_USE_CACHE=yesが利用できるのが、nss3.16以上とあるが、

nss-softokn-3.14.3-12.el6 という情報もあるため、確認

この場合、NSS/3.21が有効なのだろうか。

poファイル生成

msginit –locale=ja –input=default.pot

poファイル生成

msgmerge –no-fuzzy-matching ja.po default.pot -o ja.new.po

msgmerge –no-fuzzy-matching ja.po default.pot -o ja.new.po –sort-by-file

と同じ。

msgmerge –no-fuzzy-matching ja.po default.pot -o ja.new.po –sort-output

は不要。poeditでもソート可。未翻訳テキストソートも。
