Hi All This rc release is still notably slower on some operations than older releases. My test case is a large project named RTEMS (a real-time OS), that we wish to import into darcs (at work) to better track our own additions and modifications. To repeat, download two adjacent releases, e.g. wget http://www.rtems.org/ftp/pub/rtems/4.9.0/rtems-4.8.1.tar.bz2 wget http://www.rtems.org/ftp/pub/rtems/4.9.0/rtems-4.9.0.tar.bz2 unpack, initialize darcs and record in the 4.8.1 tree, then copy _darcs to the 4.9.0 version and try to record -l or whatsnew -l. I have two darcs versions installed: ben@sarun[1]: .../rtems/rtems-4.9.0 > /usr/local/bin/darcs --version 2.2.1 (release) ben@sarun[1]: .../rtems/rtems-4.9.0 > darcs --version 2.3.99.2 (release candidate 2) ben@sarun[1]: .../rtems/rtems-4.9.0 > time /usr/local/bin/darcs whatsnew -l # ...long output elided... /usr/local/bin/darcs whatsnew -l 381,45s user 6,34s system 92% cpu 7:00,90 total whereas with 2.3.99.2 it goes ben@sarun[1]: .../rtems/rtems-4.9.0 > time darcs whatsnew -l Well, it is still running after 18 minutes! Top reports something like PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 5702 ben 20 0 1112m 933m 3628 R 92.2 28.3 18:26.08 darcs One point to notice is that 2.3.99.2 has not yet reported any progress, whereas 2.2.1 almost immediately starts reporting something about pristine trees followed by the usual number/number stuff; and the numbers continually rise. The situation with record is similar. I admit that the huge RTEMS tree with over 7000 changes between the two releases is challenging. However, earlier releases can do it (though it takes long, much longer than with, say, mercurial). At work I tried it with 2.3.1 (on a fast 4 processor machine) and it recorded all the changes in about one minute. I think this regression should be fixed before 2.4 is released.

The darcs team would like to announce the immediate availability of darcs 2.4 release candidate 2. darcs 2.4 will contain many improvements and bugfixes compared to darcs 2.3.1. Highlights are the faster operation of record, revert and related commands, and the experimental interactive hunk editing. This beta is your chance to test-drive these improvements and make darcs even better.
