if... = false. An anti pattern I see a lot in the codebase.
This should be a hanging offense, especially since
If Notis used further down in the code, so whoever wrote that has to know about it. On the other hand, having to code in VB is probably punishment enough.

The Linux file system layer is called "Virtual File System". This makes no sense as all file systems are equally virtual.
Also, who the hell writes quotes like this?

The kernel doesn't even remember the file name after opening it.
Why should it? You can remove or move or rename it and all that matters is the handle to the inode. On the other hand, on windows you cannot delete/move/rename a file that has an open file handle!
@anonymous234 said in WTF Bites:
So if you want to make a dynamic file system, let's say /proc/, you can't just parse the address "/proc/1234/mem" whenever someone requests it, no, you have to generate all the files you want on the first time anyone reads /proc/1234, then invent a new number for each of those, then add the names and numbers to a table in memory and keep it forever in case someone requests file 123458266.
Are you talking about FUSE?
Why do you want to emulate/proc? Do you also emulate Windows registry very often?
-
@dse remembering the path and name of a file should not be mutually exclusive with being able to move/rename/delete the file while it is open. Though I would argue that it doesn't make much sense to delete an open file.

If a file can have more than one name, why can't it have zero names?
Think about it this way - you can create a temporary file on Linux without giving it a name. If your program crashes, there's nothing to clean up.
You can create a file and populate its contents before giving it a name. No more making foo.zip.tmp and renaming it.
-
@ben_lubar @dse I agree that not having any names is not the same as deleting the file. I would be satisfied if there was a function that, given the file ID/handle/whatever, gave you a list of all the names. I would not be satisfied if the file I was reading was suddenly deleted.
-

You wouldn't notice. As long as you hold the file handle, the file's contents will remain readable to you (ok, technically, somebody could go and manually truncate the file before deleting it, but that's not commonly done).

Oh, and the entire file system design DEPENDS on each file having an inode and each inode being directly indexable by number. The kernel doesn't even remember the file name after opening it.

Real fucking forward thinking there.
Actually modern kernels do hang on to the original name - it's in the
/proc/self/fd/*symlinks.Also, I expect the inode values in /proc are computed (since that's how I'd do it). Combined with either hardcoded or assigned-during-registration sequence numbers for specific files.

A file without any names is deleted when no process has it open anymore, or (I think) when the filesystem is mounted.

@anonymous234 said in WTF Bites:
in standard kernel wording "get" means "allocate and fill", "read" means "fill" and "put" means "release"
No, ‘get’ means “get me a reference I can use, whatever it takes”. What it takes depends on the type. For most it simply increments reference count, but for some it looks up in cache and reads it if it's not there. ‘put’ is then simply opposite of ‘get’. Yes, ‘release’ is more common for this.
I guess "fill" and "release" would have been too easy.
‘fill’ wouldn't have made sense. You can fill a structure in many different ways, so saying ‘fill’ does not capture the intent. Instead you either want to ‘get’ it, reusing cached data if possible, or you want to ‘read’ it, creating a new instance.
@anonymous234 said in WTF Bites:
DEPENDS on each file having an inode
Well, in memory it does. The on-disk or on-network or whatever representation does not need anything like that.
and each inode being directly indexable by number
No, it does not. The inode cache is indexed by number, but VFS does not use that functionality. It is just a utility for filesystems that do have inodes on-disk, because that's majority of them. But if you don't have numbers, you can fill in garbage and nothing will break (you probably want to fill in unique grabage in case userland depends on them for hardlink detection). Been there, done that.
@anonymous234 said in WTF Bites:
you can't just parse the address "/proc/1234/mem"
Obviously. Because the “/proc” part is not under your control.
@anonymous234 said in WTF Bites:
keep it forever in case someone requests file 123458266.
No, you don't, because nobody can. Requesting files by inode number is only possible when the filesystem is exported over NFS; and it might also be a thing in FUSE to keep the caches in sync, though I am not sure.
So when it drops from the icache, you simply repopulate it with new pseudo-random inode and everything will be just fine.
-
Also, I expect the inode values in /proc are computed (since that's how I'd do it). Combined with either hardcoded or assigned-during-registration sequence numbers for specific files.
I decided to check. On an EL5 system, the inodes in
/proc/<pid>are of the formpid << 16 + C, where C varies per file. Nodes in both/proc/<pid>/fdand/proc/<pid>/fdinfoare of the formpid << 16 + 0x8000 + fd. (So the same FD has the same inode in both of those, but one is a symlink and the other is a plain file, and hardlink count is 1).EL6/7 systems do not return consistent inode numbers, sometimes even between
statcalls.

Chernobyl: Capping a Catastrophe (Published 2014)
A 32,000-ton arch that will end up costing $1.5 billion is being built in Chernobyl, Ukraine, to all but eliminate the risk of further contamination at the site of the 1986 nuclear reactor explosion.
Artur Korneyev, 65, a radiation specialist, at his home in Slavutich. After the accident, his job was to locate radioactive fuel on site and determine radiation levels to limit the exposure of other workers.
For those to lazy to read the article, same guy said this:
These days Mr. Korneyev works in the project management unit, but because of his health — he has cataracts and other problems related to his heavy radiation exposure during his first three years — he is no longer allowed inside the plant. “Soviet radiation,” he joked, “is the best radiation in the world.”

And if I may attempt some
. The reactor did explode. Twice. Just because the nuclear fuel itself in incapable of exploding doesn't mean a reactor can't explode. In this case, the first explosion was caused by steam pressure buildup. Which would get pretty damn high from a runaway nuclear reaction in a water-cooled reactor with non-working pumps.

Windows Phone is dead, so Microsoft wants you to buy a Galaxy S8
WINDOWS PHONE is struggling to maintain any significant market share, but fortunately, Microsoft has now rolled-out a customised edition of the Samsung Galaxy S8 to its brick-and-mortar retail stores.
In case the Daily Express ever bothers to hire an editor, the headline is 'Windows Phone is dead, so Microsoft now thinks you to buy a Samsung Galaxy S8'.
-
The operating system dropped from a 1.2 per cent market share at the end of 2015, to a new low of 0.3 per cent by the end of Microsoft's third financial quarter in 2016.
MS can turn that around if they spend more than $0 a year on advertising the damn things.
Anyway, good thing the S8 has no major issues, right?
The Galaxy S8 has a MAJOR problem and Samsung knows it
Samsung Galaxy S8 is available to pre-order now but there's a major issue with this flagship smartphone that could become hugely irritating.
Oh.

@Atazhaia Obligatory educational link:
http://imgur.com/a/TwY6qIMO the most interesting part:
- At 01:23:04, turbine 8 was disconnected and began to coast down. Within seconds, the main circulating pumps began to cavitate and fill with steam, reducing the flow of valuable cooling water and allowing steam voids (pockets of steam where there should be water) to form in the core. A positive void coefficient was occurring: the absence of cooling water causing an exponential power increase.
- At precisely 01:23:40, Akimov pressed the emergency shutdown button.
- At precisely 01:23:58, a mere 18 seconds after Akimov pressed the SCRAM button, a steam explosion blew the 450-ton upper biological shield clear off the reactor before it crashed back down, coming to rest at a steep angle in the raging maw it left behind. The core was exposed.
Literally just 54 seconds between the moment things start to definitely go wrong and the massive explosion.
