Status: RESOLVED FIXED

(Calendar :: Internal Components, defect)

Description

[Scott Wilson]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-us) AppleWebKit/125.4.2 (KHTML, like Gecko) Safari/125.9
Build Identifier: 

The .ics file generated by Sunbird is considered to be corrupted by Apple iCal 1.5.2 (v638). (will attach)

Reproducible: Always
Steps to Reproduce:
1. Place the attached .ics on a WebDAV server
2. Run iCal
3. Subscribe
Actual Results:  
iCal generates the message:

Downloaded file is not a calendar or file is corrupted on server.
The calendar may be just in a middle of an update so retrying later may fix the problem.

Expected Results:  
The calendar should have updated correctly in iCal; at this point it is unclear whether Sunbird or iCal is 
at fault.

What version of Sunbird and what platform was this file generated on?
The linefeeds are incorrect. Instead of CRLF most lines have CRCRLF.
This might be a regression caused by the fix to bug 254356

Never mind. Found the cause. On windows, ics files are opened as O_TEXT not
O_BINARY so each \n is written as \r\n causing the CRCRLF (\r\r\n) entry.
This change makes sure the file is opened in binary mode on windows:

The bugspam monkeys have been set free and are feeding on Calendar :: Internal Components. Be afraid for your sanity!
