      [ni] defensively parse outbound attachments to prevent NPE on resend · f8818bf2

      * when resending rate-limited messages, signald throws an NPE when
        trying to read construct a file handle from the
        `attachment.filename` field
      this is the error message:

      * signald is throwing an NPE, because we tried to parse
        `outSdMessagefilename` from `request.storedFilename`, when in fact
        `request` was providing us `request.filename`.
      * as a result `outSdMessage.filename` was undefined, so when we passed
        it to `File attachmentFile = new File(attachment.filename);`
        in `signald.SocketHandler.send(SocketHandler.java:233)`,
        `attachment.filename` is null and the constructore throws an NPE
      * defensively try to parse a `filename` field from either
        `storedFilename` (if present), `filename` (if not), or provide an
        empty string
      * in the ideal case, this grabs the filename from whatever field it
        was provided in
      * as a fallback, it at least prevents the original NPE by providing an
        empty string, which will prevent `new File` from crashing, but cause
        `new InputFileStream` to throw a `FileNotFoundException`, which
        fortunately is okay (or at least better), because that exception is
        handled by signald and should give us slightly better reporting and
        ability to recover?

      aguestuser authored
      * SYMPTOM: halting error when attempting to resend a rate-limited
        message that contained attachment. crashes due to deserialization
        error with message: "Cannot deserialize instance of
        `java.lang.String` out of START_OBJECT token"
      * CAUSE: we were failing to transform attachments from their inbound
        format to their outbound format (and yes, it's annoying that signald
        uses a different format for inboud and outbound attachments!)
      * FIX: parse outbound attachments the first time we resend a message
        and alter the hashing algorithm such that it hashes a field that is
        not removed during that parse step (ie: use the filename,not the digest)

      aguestuser authored
      * MR !165 implemented an exponential backoff resend queue for
        rate-limited messages, but it got the type of signald `attachments` wrong
        (they are objects not strings, and thus, not directly hashable)
      * this fixes that by hashing one of the (unique) fields on each
        `attachment` in an `SdMessage`

      [186] enqueue rate-limited messages in top-level dispatch code · b043ca24
      aguestuser authored
      * modify `enqueueResend` to:
        * have "fire-and-forget" semantics, ie: return immediately without waiting for enqueued resend to be attempted
        * return the interval it will wait before attempting enqueued resend
      * modify `dipatcher.run.dispatch` to:
        * hold a reference to a module-local `resendQueue` hash map created in `dispatcher.run.run` (which it will use to track state of resent messages)
        * enqueue resend for rate-limited messages identified by `detectRateLimitedMessage` helper
        * include attempted resend interval in admin notification about rate limit

      * keep a queue of resent messages and the interval that was waited
        before sending them
      * every time a message errors, resend it waiting double the last
        interval we waited last time
      * when we resend a message for the first time, we add it to the queue
        and resend at a specified minumum threshold (2 sec)
      * when a message exceeds a threshold (256 sec), don't resend it anymore and
        delete it from the queue
