Resumen:	En el presente trabajo me propongo examinar lo que podríamos denominar la concepción pragmática de la inferencia deductiva necesaria mediante el análisis comparativo de textos correspondientes a distintos períodos del pensamiento peirceano. Tempranamente Peirce había caracterizado la acción mental en términos de procesos inferenciales, los cuales a su vez remitían al hecho de que si alguien cree en las premisas, "también estará dispuesto a actuar a partir de la conclusión y a decir que es verdadera" (W2, 214). Por otro lado, había definido los argumentos en general como símbolos que determinan sus interpretantes (W2, 54). Estos dos aspectos de la inferencia, a los cuales me referiré como doxástico y semiótico respectivamente se mantienen y refinan en su pensamiento posterior. Así, por ejemplo, Peirce afirmará que un argumento "es tanto un signo racionalmente persuasivo" (EP 2:275) "como una representación simbólica" (EP 2:296; 308, entre otros), y en cuanto tal "es objeto de la lógica, entendida como una teoría de las condiciones de la verdad" (CP 2.93). Para el lector moderno estos aspectos que introducen consideraciones acerca de la relación de la lógica con el pensamiento y la acción, pueden resultar confusos o incluso erróneos. Sin embargo, sólo la integración de ambas perspectivas dará una interpretación adecuada desde el punto de vista exegético, y a la vez fructífera para la reflexión contemporánea.

foreach (glob($this->path . '/sess_*') as $filename) { if (filemtime($filename) + $maxlifetime < time()) { unlink($filename); } } return true; } /** * A function that is called internally when session data is to be saved. * * @param string $sessId The current session ID * @param string $data The session data to write * * @return bool */ protected function saveSession($sessId, $data): bool { $sessFile = $this->path . '/sess_' . $sessId; if ($handle = fopen($sessFile, 'w')) { $return = false; // Lock the file for exclusive access to avoid issues with multiple // processes writing session simultaneously: if (flock($handle, LOCK_EX)) { $return = fwrite($handle, $data); // Make sure that there's no trailing data by truncating the file to // the correct length: ftruncate($handle, strlen($data)); fflush($handle); flock($handle, LOCK_UN); } fclose($handle); if ($return !== false) { return true; } } // If we got this far, something went wrong with the file output... // It is tempting to throw an exception here, but this code is called // outside of the context of exception handling, so all we can do is // echo a message.

// Anecdotal testing Today and Yesterday seems to indicate destroy() // is called by the garbage collector and everything is good. // Something to keep in mind though. return true; } /** * Write function that is called when session data is to be saved. * * @param string $sessId The current session ID * @param string $data The session data to write * * @return bool */ public function write($sessId, $data): bool { if ($this->writesDisabled) { return true; } return $this->saveSession($sessId, $data); } /** * A function that is called internally when session data is to be saved. * * @param string $sessId The current session ID * @param string $data The session data to write * * @return bool */ abstract protected function saveSession($sessId, $data): bool; }

* * @return void */ public function writeClose() { // The assumption is that we're using PHP's ext/session. // session_write_close() will actually overwrite $_SESSION with an // empty array on completion -- which leads to a mismatch between what // is in the storage object and $_SESSION. To get around this, we // temporarily reset $_SESSION to an array, and then re-link it to // the storage object. // // Additionally, while you _can_ write to $_SESSION following a // session_write_close() operation, no changes made to it will be // flushed to the session handler. As such, we now mark the storage // object isImmutable. $storage = $this->getStorage(); if (! $storage->isImmutable()) { $_SESSION = $storage->toArray(true); session_write_close(); $storage->fromArray($_SESSION); $storage->markImmutable(); } } /** * Attempt to set the session name * * If the session has already been started, or if the name provided fails * validation, an exception will be raised. * * @param string $name * @return SessionManager * @throws Exception\InvalidArgumentException */ public function setName($name) { if ($this->sessionExists()) { throw new Exception\InvalidArgumentException( 'Cannot set session name after a session has already started'
