BUG: bulk download stuck

Open coccoalberto97 opened this issue 2 years ago • 2 comments

OkDownload Version

1.0.7

Problem Describe

Randomly (that happened 20% of the times so far) when trying to download files in bulk (900MB - 600 files) the queue gets stuck and it stops emitting events:

this is the code I'm using to set up the bulk download:

DownloadContext.Builder builder = new DownloadContext.QueueSet()
                        .setParentPathFile(new File(context.getCacheDir().toString() + File.separator + "tmpapp"))
                        .setMinIntervalMillisCallbackProcess(300)
                        .commit();
                for (int i = 0; i < downloadTasks.size(); i++) {
                    //downloadTasks list of MyDownloadTaskClass 
                    MyDownloadTaskClass task = downloadTasks.get(i);
                    builder.bind(task.url).addTag(0, task.filename).addTag(1, task.savedDir).addTag(2, task.finalDir).addTag(3, i);
                }

                DownloadContext downloadContext = builder.setListener(new DownloadContextListener() {

                    @Override
                    public void taskEnd(@NonNull DownloadContext context, @NonNull com.liulishuo.okdownload.DownloadTask task, @NonNull EndCause cause, @Nullable Exception realCause, int remainCount) {
                        final int index = (int) task.getTag(3);
                        synchronized (updateFileNumberLock) {
                            switch (cause) {
                                case COMPLETED:
                                    break;
                                case PRE_ALLOCATE_FAILED:
                                case FILE_BUSY:
                                case ERROR:
                                case CANCELED:
                                    log("failed at index " + index);
                                    if (index < downloadTasks.size()) {
                                        failedTasks.add(downloadTasks.get(index));
                                        failedDownloads++;
                                    }
                                    break;
                            }
                            downloadedFiles++;

                        downloadFinished = true;
                        log("QUEUE END");
                    }
