折腾:

【未解决】lnmp中php警告:wp-cron.php execution timed out terminating

期间,需要搞清楚,对于php的slow的log中所反映出的evernote-sync的死掉的位置时候输出:

对应着源码的地方是哪里,以及调用的顺序。

evernote-sync github

Evernote Sync — WordPress Plugins

jicksta/sync-evernote: Dockerized Evernote synchronizer

别人写了个sync的工具,但不是我要的。

evernote/evernote-thrift: Thrift IDL files for the Evernote Cloud API

cbednarski/evernote-sync

Documentation – Evernote Developers

下载了源码:

https://downloads.wordpress.org/plugin/evernote-sync.zip

去看看

确认了,代码是由下往上的调用的

至少是:

[0x00007f36452d7220] findNotes_listNotebooksWithContext() /home/wwwroot/www.crifan.com/wp-content/plugins/evernote-sync/src/Evernote/Client.php:807

-》

[0x00007f36452d73b8] listNotebooks() /home/wwwroot/www.crifan.com/wp-content/plugins/evernote-sync/src/Evernote/Client.php:971

最后卡死在:

  /**
   * Opens and sends the actual request over the HTTP connection
   *
   * @throws TTransportException if a writing error occurs
   */
  public function flush() {
。。。
      $contextid = stream_context_create(array(‘http’ => $options));
    $this->handle_ = @fopen($this->scheme_.’://’.$host.$this->uri_, ‘r’, false, $contextid);

也是

https://github.com/Automattic/php-thrift-sql/blob/master/src/Thrift/Transport/THttpClient.php

看到的那样。

后来去搜:

listSharedNotebooks send_listSharedNotebooks

EverNote Business API – AttributeError: ‘str’ object has no attribute ‘writeMessageBegin’ – Evernote API Discussion – Evernote User Forum

NoteStore.Client

【总结】

最后几步的代码调用分别是:

/Users/crifan/dev/dev_root/crifan.com/evernote-sync/evernote-sync/src/EDAM/NoteStore/NoteStore.php

    public function listSharedNotebooks($authenticationToken)
    {
        $this->send_listSharedNotebooks($authenticationToken);
        return $this->recv_listSharedNotebooks();
    }
    public function send_listSharedNotebooks($authenticationToken)
    {
        $args = new \EDAM\NoteStore\NoteStore_listSharedNotebooks_args();
        $args->authenticationToken = $authenticationToken;
        $bin_accel = ($this->output_ instanceof TBinaryProtocolAccelerated) && function_exists(‘thrift_protocol_write_binary’);
        if ($bin_accel)
        {
            thrift_protocol_write_binary($this->output_, ‘listSharedNotebooks’, TMessageType::CALL, $args, $this->seqid_, $this->output_->isStrictWrite());
        }
        else
        {
            $this->output_->writeMessageBegin(‘listSharedNotebooks’, TMessageType::CALL, $this->seqid_);
            $args->write($this->output_);
            $this->output_->writeMessageEnd();
            $this->output_->getTransport()->flush();
        }
    }

/Users/crifan/dev/dev_root/crifan.com/evernote-sync/evernote-sync/src/Thrift/Transport/THttpClient.php

  /**
   * Opens and sends the actual request over the HTTP connection
   *
   * @throws TTransportException if a writing error occurs
   */
  public function flush() {
    // God, PHP really has some esoteric ways of doing simple things.
    $host = $this->host_.($this->port_ != 80 ? ‘:’.$this->port_ : ”);
    $headers = array();
    $defaultHeaders = array(‘Host’ => $host,
                            ‘Accept’ => ‘application/x-thrift’,
                            ‘User-Agent’ => ‘PHP/THttpClient’,
                            ‘Content-Type’ => ‘application/x-thrift’,
                            ‘Content-Length’ => TStringFuncFactory::create()->strlen($this->buf_));
    foreach (array_merge($defaultHeaders, $this->headers_) as $key => $value) {
        $headers[] = "$key: $value";
    }
    $options = array(‘method’ => ‘POST’,
                     ‘header’ => implode("\r\n", $headers),
                     ‘max_redirects’ => 1,
                     ‘content’ => $this->buf_);
    if ($this->timeout_ > 0) {
      $options[‘timeout’] = $this->timeout_;
    }
    $this->buf_ = ”;
    $contextid = stream_context_create(array(‘http’ => $options));
    $this->handle_ = @fopen($this->scheme_.’://’.$host.$this->uri_, ‘r’, false, $contextid);
    // Connect failed?
    if ($this->handle_ === FALSE) {
      $this->handle_ = null;
      $error = ‘THttpClient: Could not connect to ‘.$host.$this->uri_;
      throw new TTransportException($error, TTransportException::NOT_OPEN);
    }
  }
