src/smblib smblib.c 1.176 1.177 smblib.h 1.85 1.86
Update of /cvsroot/sbbs/src/smblib
In directory cvs:/home/rswindell/sbbs/src/smblib

Modified Files:
smblib.c smblib.h
Log Message:
Re-write of smb_getmsgidx_by_time() - using a proper binary search
algorithm now. Also, now returns the index offset of the matched index
(if found), negative error value otherwise.

I was testing something and noticed that the old smb_getmsgidx_by_time() implementation could sometimes return the index of a message posted before
the requested time. That was fixed by re-writing the binary search logic.

Also, I found it useful in my testing to have this function return the
offset of the matching index (in addition to the index record itself), so checks of the return value need to compare >= SMB_SUCCESS, not just ==
or != SMB_SUCCESS.

src/smblib smblib.c 1.179 1.180 smblib.h 1.86 1.87
Update of /cvsroot/sbbs/src/smblib
In directory cvs:/tmp/cvs-serv5685/smblib

Modified Files:
smblib.c smblib.h
Log Message:
Singificantlly improve message scan pointer initialization (e.g. for new
users) and adjusting scan ptrs by date or set to "Last msg" while online:
- speed (on my system, reduced from 12 to < 2 seconds)
This involved 2 enhancements: check msgbase index file timestamp (fast)
before opening any files. When opening the msgbase, just open the index
file (no other msgbase files) - required new smblib function: smb_open_index. - fixed off-by-one when setting by date (when setting the new-scan ptr to
Jan-1-2018, you want that first message posted on/after Jan-1-2018 to be
found as "new", not the first message posted *after* that date.
- re-added the fixmsgptrs() call in putmsgptrs(), inadvertently removed
in the .ixb -> .ini ptr storage update in rev 1.192 of userdat.c.
