[jira] [Commented] (CB-2840) crash when disabling network
connection during file download
[ https://issues.apache.org/jira/browse/CB-2840?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13646515#comment-13646515 ]
Sanchit Bahal commented on CB-2840:
-----------------------------------
I am also facing a similar issue with Cordova 2.5.0 while downloading multiple files from a server. The issue is consistently reproducible, and the way I do it is by manually killing the server while the download is in progress.
The really strange thing that seems to be happening in this case is that while most of the downloads fail with error code 3 (Connection error, I guess), few downloads finish successfully with the response code 200 (even though the server is no longer available). And when I check the contents of these files, they have been only partially downloaded.
Here is an excerpt of the logs for the same:
