Description
I noticed that in a plain-text file, letter.txt, I had recently worked on yesterday using StyledEdit, after upgrading to hrev47114, there was a chunk of text that stood out:
'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<'<
That not being part of my letter, I investigated, and found that that above sequence had replaced a chunk of my letter. Interestingly, the replaced chunk was found, intact, in the alphabetically next file in the same directory, "letter.txt copy". However, in "letter.txt copy", the intact chunk had taken over all but the last 54 bytes of the original "letter.txt copy". Both "letter.txt copy" and "letter.txt copy 2", which have the exact same modified date and size (and that may have been me hitting alt-d twice by accident back when I was working on letter.txt) but "letter.txt copy 2" had no data replaced. I hadn't experienced any StyledEdit crashes or anything. Does such a weird double-displacement mean my HD is on its way out, or is this a possible bug in Haiku? This is a file on the BFS boot volume that my Haiku nightly is running off of, without any other data corruption found yet.

Sorry, I'm not able to provide it anymore at this point, but if it happens again, I certainly will.
I am running an AMD Sempron 64, yes. What does that mean for this?

Quite oddly, I just had this happen (hrev 47209) with a file where it overwrote text from a file in another directory. The file it come from? Ironically, syslog. This is what my file suddenly contained, after a normal usage pattern of opening in StyledEdit, adding/changing text, saving, closing:
Say someone makes a subtle change to inventory policy, and it brERN: address 0x10ffff; pin 2; source 0x821d27f8 0; pci 0:16 pin 3 func mask 10; bios irq: 5; gsi 21; config 0x06 KERN: address 0x11ffff; pin 2; source 0x821d2738 0; pci 0:17 pin 3 func mask 20; bios irq: 5; gsi 22; config 0x06 KERN: address 0xfffff; pin 0; source 0x821d28b8 0; pci 0:15 pin 1 func mask 2; bios irq: 255; gsi 20; config 0x06 KERN: address 0xfffff; pin 1; source 0x821d28b8 0; pci 0:15 pin 2 func mask 1; bios irq: 11; gsi 20; config 0x06 KERN: address 0xffff; pin 0; GSI 16; pci 1:0 pin 1 func mask 1; bios irq: 10; gsi 16; config 0x06 KERN: found interrupt override for bus 0, source irq 0, global irq 2, flags 0x00000000 KERN: found interrupt override for bus 0, source irq 9, global irq 9, flags 0x0000000f Kto make sure that an error message is shown when it should be.

It turns out that the 728 bytes beginning with "ERN: address" and ending with "K" just before "to make sure" overwrote exactly 728 bytes of original text, when I checked with a backup I had of the file.

Just occured to me today, or yesterday. Hadn't seen that in over a year. StyledEdit was involved again.. Not sure what's special about it that makes it trigger this BFS bug, whereas no other app does..
Note -- this is my main dev machine so I won't be able to keep it "as is" for forensics very long, I have to restore the files soon..
Syslog -- mentions block already set!:

checkfs mentions things, but seemingly not relevant to the involved files:
~/Desktop> checkfs --check-only /boot
DayTracker-0.0-1-x86_gcc2.hpkg (inode = 1638255), some blocks weren't allocated
activated-packages (inode = 10026999), some blocks weren't allocated
activated-packages (inode = 7077851), has blocks already set
6084 nodes checked,

indirect block runs 739 (in 51 array blocks, 36.35 GiB)
double indirect block runs 0 (in 0 array blocks, 0 bytes)
EDIT: silly me, should run it on the actually concerned partition.. Though oddly enough it does not show anything like the syslog "block already set" error:
~/Desktop> checkfs --check-only /SamZulu/
134912 nodes checked,
0 blocks not allocated,

inodes listing (I remember seeing that in a message from Axel, so might as well provide it here):

Here's the files involved; the stylededit file is slightly corrupted in the end, but the armyknife App.cpp file is in a sorry state, 99% lost (got a recent backup fortunately):

NOTE: the corruption ending and startpoint are at the same offset, that is to say offset 0x800, interesting no ? Plus there's some truncation going on I think (gotta check but App.cpp was longer than its today's length).
I think I'm going to blacklist StyledEdit from my system altogether.. It's not like this laptop is supposed to be a Quality Assurance machine running torture tests on Haiku *g*

Tentatively setting to high, though since only StyledEdit seems to trigger this maybe that's over-reaching..
comment:9 by , 10 years ago
Since it seems to be BTextView specific, can you check if it's been fixed in hrev47878 ?

If BTextView is the culprit, rather than a simple 'trigger', that is worth a test indeed.. The problem is that I'm in a rush with work (next release of TT) and I could not focus on this ticket even if this was on a spare computer.. let alone my main laptop here.
For what it's worth, I (hopefully) circumvented any future bug occurence by changing FileTypes so that MIME type "text" invokes Pe, not StyledEdit (this might be helpful to Kev).
Anyway, now undoing my priority change (otherwise it would be bad form to say "I want this to be fixed but I'm not willing to test!") in recognition that this is not necessarily a BFS bug.. There's a possibility that StyleEdit's entry_ref "slips" into changing another file.. though the odds of that appear slim doesn't it..
EDIT (JAN15): there's also a faint possibility that #11721 was somehow involved with triggering this, considering the bug seems to occur on styled text.. Still not volunteering to corrupt my volume with StyledEdit testing though !

Dunno about the O.P., but this has been completely non-reproducible from where I stand -- i.e. with StyledEdit blacklisted. No mysterious corruption in 4 years, just the occasional need to 'checkfs' to fight entropy. So seems the "work-around" is quite successful.

It's more likely the StyledEdit memory fixes mentioned above fixed it. But it's possible I suppose.
comment:15 by , 4 years ago
It seems possible that #16605 might be related to this, though the offset of the corruption is not mentionned (is it 0x80 too ?)
Out of curiosity, are you able to provide a syslog? Do you happen to be running an AMD cpu?
