hellow everyone:
      When i try to learn the implementation that subversion makes delta
data saved, i have found that when i commits a modified text file, there
will be some copies to save in dir .svn/tmp/text-base.
      Are those copies in .svn/tmp/text-base to used to calculate delta
data?
      In code file /libsvn_wc/adm_crawler.c, i guess the function
svn_wc_transmit_text_deltas2 tries to make delta data and send it to server,
but i do not find how to calculate the dalta data, just to find how to make
md5 checks..
     Could you tell me the subversion how to implement to calculate the
delta data? Does it use function strcmp or memcmp to implement?
    thank you for all respones.
