eyefiserver2

4月にTrusty化したML110G7でまだ十分に動作確認ができていなかったのが、昨年5月に導入、1月に改修したeyefiserver2。

先日Trusty化したGT110bではすんなり動いているように思っていたのだが、実はpyexiv2関連で発生したExceptionによってSOAPの応答が発行されず、電源が入る度にEye-Fiカードがアップロードを繰り返していた事が判明。

よくよく調べてみると、昨年5月のUbuntu 10.04ではlucidなpython-pyexiv2がバージョン 0.1.3だったので、APIはレガシーなpyexiv2.Imageやexif.readMetadataを使用する必要があったのだが、preciseなpython-pyexiv2以降はバージョン 0.3.2になっているのでpyexiv2関連のAPIはモダンなpyexiv2.ImageMetadataやexif.readに戻す必要があったという事だ。
