How does RTC know file change

Rubin Zheng (16●9●8) | asked Aug 05 '11, 10:21 a.m.
Hi

During a automatic/manual fresh, RTC could recognized the file change immediately. May I know the internal mechanism how RTC know the change? based on time stamp or something like md5sum? where RTC store the information for each file and directory?

Another question is if RTC download component content incremental when I change my repository workspace flow target to another stream? If most content is the same, will RTC download the change only?

Thanks for any feedback!

RTC does store some kind of SHA in the repository for each file version,
so does not depend on just the date stamp to determine whether a file
has changed.

On the second question, yes, the content download in that case will
still be incremental (changes only).

Cheers,
Geoff
