I thought that sources is a general purpose fossil server that archives
everything in venti dumps, but apparently not:
term% 9fs sourcesdump
term% ls -l /n/sourcesdump/2008/1225/dist/replica
term%
In fact, if one looks at the /n/sources/dist/replica it seems
that the directory itself was last modified on Nov 23, but
the files are from Nov 18:
term% ls -ld /n/sources/dist/replica
d-rwxrwxr-x M 22 glenda sys 0 Nov 23 23:00 /n/sources/dist/replica
term%
--rw-rw-r-- M 22 glenda sys 922 Nov 18 23:01 /n/sources/dist/
replica/cd
d-rwxrwxr-x M 22 glenda sys 0 Nov 18 23:01 /n/sources/dist/
replica/client
--rw-rw-r-- M 22 glenda sys 237 Nov 18 23:01 /n/sources/dist/
replica/fossil
--rwxrwxr-x M 22 glenda sys 542 Nov 18 23:01 /n/sources/dist/
replica/inst
--rwxrwxr-x M 22 glenda sys 1086 Nov 18 23:01 /n/sources/dist/
replica/network
--rw-rw-r-- M 22 geoff sys 5763789 Nov 18 23:31 /n/sources/dist/
replica/sources.db
--rw-rw-r-- M 22 geoff sys 7158415 Nov 18 23:28 /n/sources/dist/
replica/sources.log
So, I tried:
term% ls -l /n/sourcesdump/2008/1123/dist/replica
term% ls -l /n/sourcesdump/2008/1124/dist/replica
term% ls -l /n/sourcesdump/2008/1118/dist/replica
ls: /n/sourcesdump/2008/1118/dist/replica: '/n/sourcesdump/
2008/1118/dist' does not exist
term% ls -l /n/sourcesdump/2008/1119/dist/replica
term%
Only to be surprised some more.
Any explanation?
Thanks,
Roman.

fossil has a dirty trick. its called DMTMP. this is for files
that aren't supposed to go to venti.
; g DMTMP /sys/include/libc.h
/sys/include/libc.h:560: #define DMTMP 0x04000000 /* mode bit for non-backed-up files */
now, taking a look at replica with the magic T flag,
; ls -lTd replica
t d-rwxrwxr-x M 161 glenda sys 0 Nov 23 23:20 replica
ken's fs does not support this trick.
