RFC: Server disk slowly failing, I plan to replace it using tip jar.
Hi,
One of the disks in the CVS/SVN/Wiki/etc server is slowly failing. I
read the daily log reports and every week or so for the past month
I've received a report of a failed sector on hda, e.g.:
WARNING: Kernel Errors Present
end_request: I/O error, dev hda, sector ...: 2 Time(s)
hda: dma_intr: error=0x40 { Uncorrect ...: 2 Time(s)
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error } ...: 2 Time(s)
Oct 4 22:40:13 raid1: hda6: rescheduling sector 18089128
Oct 4 22:40:19 raid1: hda6: redirecting sector 18089128 to another mirror
So in order to prevent data loss, I'd like to replace the HDD. I'm
considering replacing it with this 250G/16M Seagate drive:
http://www.newegg.com/Product/Product.aspx?Item=N82E16822148143
Actually, I'd like to order TWO of these drives. No, we don't really
need the extra space (we still have 40G free on /home, out of 56G
using a pair of 80G drives in RAID1), but I might as well replace both
drives at the same time as they're both about the same age. This is
the cheapest 16MB cache drive I could find, and it's one of the
cheapest Seagate drives I could find (the only cheaper Seagate had
only a 2MB cache).
Granted, I could save $20 per drive by going with a 200G/8MB Maxtor:
http://www.newegg.com/Product/Product.aspx?Item=N82E16822144211
I'm really hoping to avoid Western Digital.
I was planning to use the tip jar for this purchase, which is why I'm
soliciting opinions before I purchase anything. Note that if I order
from NewEgg I can usually have the item delivered the next day. On
the other hand I wont have time to work on the hardware until probably
October 27-28, so we have a little time to come to consensus.
So... Comments? Suggestions?

A I'd say go for it with the 16MB cache Seagates, too. Pulling myself out of the temporary poverty that is college, I couldn't add much to the tip jar. But I appreciate a software project that has been solid for me for a couple of years now. ___ gnucash-devel mailing list gnucash-devel@gnucash.org https://lists.gnucash.org/mailman/listinfo/gnucash-devel

The warning was TransLog.c:254: warning: the address of 'drecn' will always
evaluate as 'true'.
Looking more into context, it turns out drecn is a local char buffer anyway,
hence it can't be NULL anyway. Because of this, here (and only here) you

- drecn ? drecn : );
+ drecn);
I suggested the {{{ drecn[0] == 0 ? [...] }}} form of the fix.
Of course, drecn[0] == 0 just means the string is already empty.
So, you're totally right; it should just be drecn.
But, there was a bit of a miscommunication about how to make the change,
anyways. As you'd quoted, if drecn[0] == 0, then the string drecn is empty,
and it'll be printed. Otherwise (when drecn actually has a value), it will
use instead.
Thanks for the code review.

I don't know how much I can actually do but I'll poke away at it here and there. If gives my computer something to do while I try to grok the gnc:html-table-foo code to try and make it a little snappier (that's the itch I'm currently trying to scratch as it now takes me a good long while to run an income statement).

Because of this, here (and only here) you should replace the expresssion direcly by drecn, i.e. - drecn ? drecn : ); + drecn); okay. I think I understand. drecn is a pointer and as such has the potential to be NULL which is very bad forthat one OS. But in this case, drecn is locally declared as a pointer to a character buffer and won't ever be NULL. hence, its okay to just pass it. right?

optimizing reports
Hi guys, I'm bent on improving the speed of some of these reports and want to bounce some ideas off you folks. The particular report I'm interested in improving is the income statement. On my smaller file (133k) it takes about 20 seconds to run a bog standard income statement. I haven't timed it on my larger file (1.4M), but it takes way too long (I usually switch over to /. please help me!). My investigation into this points to the function gnc:html-acct-table-add-accounts! in reports/report-system/html-acct-table.scm. This function appears to be the workhorse of the income statement but is also used in balance sheet, budget and trial balance reports, so fixing it would likely help those guys as well. Currently the report recurses through the account tree gathering totals for each account and it sub accounts. It appears that it walks all the way out to the leaf nodes at each level, so that the sub account totals get calculated repeatedly making this a hugely inefficient function. For example, giving this: Toplvl--- A --- A1 |-A2 |-A3 |-A4A4a |-A4b To calculate the balances of all these, it would calculate the whole tree for the balance ot Toplvl; re-calculate all of A sub-tree to get A's balance; re-calculate A1; re-calc A2; re-calc A3; re-calc the whole A4 sub-tree; then re-calc A4a; re-calc A4b etc etc etc... bad. I want to clean that up and what I'm thinking is to recurse through the tree once totalling up each relevant account and returning those totals in some structure that contains the accounts and their totals. Then walk through the tree generating the output table based on the required depth. This means I'd still be walking a tree structure twice, but I'd only be doing the per-account math once. I imagine the first walk would end up returning a list of toplevel accounts, each member of which would be a cons of that account's balance and a list of it subaccounts, each member of which would be a cons... you get the idea. So before I start hacking my fingers off, does this idea make sense? (it does to me...) or is there something blatantly obvious that I'm missing in this general idea? Also, if I'm mis-reading that code, please let me know, but I think I have the gist of it pretty well.
