[darcs-devel] [issue198] darcs get --to-match extremely slow

[Andrew McGregor]

New submission from Andrew McGregor <andrew at indranet.co.nz>:

When I do something like:

darcs get --verbose --to-match "hash  
20050421043628-8498e-6fac25ad05cf9a870c0eee854fb4ff386a271268" /home/ 
Repos/unstable/ /home/andrewm/test

at the "Writing working directory" stage darcs takes many minutes and  
does several GB of IO... yet:

  zcat /home/Repos/unstable/_darcs/patches/ 
20050421043628-8498e-6fac25ad05cf9a870c0eee854fb4ff386a271268.gz | wc
   27731  105819  771252

the patch is only 771kB, and consists entirely of 131 new files.  The  
target repository is empty to start with, the source repository  
contains 282 patches totalling 255MB gzipped.
