[jira] [Commented] (CB-7862) FileReader reads large files in a single chunk causing OOM exceptions

["Tony Leung (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CB-7862?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15417828#comment-15417828 ] 

Tony Leung commented on CB-7862:
--------------------------------

Now that the chunk size is - FileReader.READ_CHUNK_SIZE = 256*1024;

I found a bug on iOS that readAsDataURL in CDVFile.m, converting it to Base64 will not work because the chunk size 262144 is not dividable by 3.

The quick fix will be FileReader.READ_CHUNK_SIZE = (256*1024) - 1
Should I open a bug for that?
