bvt: diana_coman: ty for spotting this. i will regring vpatches p.1 and p.2; i wanted to make the vpatch p.1 name the same in manifest and file system, but did the wrong thing there just editing the line from previous vpatch in vpatch p.2.
diana_coman: and given the two-class system those are effectively priorities: at every ask-opportunity, the Requester will choose first object request and only second file request (those really are the ONLY two types of questions the client may ask the server)

phf: trinque: i'm going to play with some link combinations, but perhaps it would be worthwhile to at least check if the named file exists on the system after failed genesis production.
BingoBoingo: I suspect file system corruption is more likely. This may mean hardware failure or it could mean an accumulation of small errors piling up during those power cycles.
asciilifeform: 'A long time ago, in the late eighties, I myself tried to develop such a system, on a home-made 68K with a cp/m executive (the file system was on a second, z80 processor, that had a floppy drive). It's name was 'li' meaning a half lisp (but it had a simple, non-optimizing JIT compiler that directly generated 68K code)...' << this is at least the 3rd fella i've corresponded with who 'i tried to build lispm in '80s out of 68k'

"files" as in ~the fucking thing REFERENCED~ in the "file"system names aren't even first class abstractions! the drive's a BYTE device! there's no fucking files ANYWHERE except in the imagination.
mircea_popescu: what passes for a "file system" currently is this attempt to force a byte-device (sometimes with some half-baked geographical allocation bolted on) through a half-baked database model. wtf is a "FAT" or a "journal" besides poorly implemented mysql/postgres dben ?

asciilifeform: mircea_popescu: i wrote about this on my www in the past, whole concept of 'file system' is consequence of the nonvolatile memory poverty that gave us the orig ram/disk split
mircea_popescu: so the situation may actually be that no computer system currently deployed actually has a file system.

asciilifeform: '...If you want to lock a file in $HOME, forget about it as $HOME might be NFS and locks generally are not reliable there. The same applies to every other file system that might be shared across the network.

ave1: Also no UNIX sockets yet, I was reading the documentation and came accross how linux now supports "abstract" unix sockets which have no equivalent on the file system. Pretty big WTF all over, it's implemented by having a string start with a 0 (zero) byte.

a111: Logged on 2018-06-27 18:03 phf: PeterL: the approach that we've been taking with legacy C code is pulling out autotools, and replacing with a single #ifdef/.. configuration header. outside of linux/bsd code is probably not going to work, and the approach is to look at the configuration header file (http://btcbase.org/patches/vdiff_sha_static/tree/vtools/src/system.h#L145 in case of vtools) and patch it for your system
a111: Logged on 2014-09-03 11:56 mircea_popescu: By default, systemd saves core dumps to the journal, instead of the file system. Core dumps must be explicitly queried using coredumpctl4. Besides going against all reason, it also creates complications in multi-user environments (good luck running gdb on your program's core dump if it's dumped to the journal and you don't have root access)
phf: asciilifeform: is it possible to combine musl and libc on a same gentoo system (gentoo insists i use something they call crossdev, i haven't yet looked into it further) (i'm using your aarch64 gentoo root file system)?

mircea_popescu: hey, you get a free db with the file system, i never was arsed to do any better on my reports. not that i'm proposing my laziness as the model for anyone else nor that i think the bikeshedding discussion needs to continue, now extented into a theoretical comparison of the merits and dismerits of postgress and implicit-fs-db.
mircea_popescu: bwahahaha "bug in npm changes permissions on / file system destroys productions linux or unix boxes. “sudo npm” will chown “/“."
ben_vulpes: shinohai: system is complaining that the file dun exist when it quite clearly does, gonna hafta look into this but not atm, thanks for chiming in
PeterL: the problem I see with the current system is that you can make a change in one file which relies on a change in behavior of a function defined in a different file. You end up with two "sister" patches, but the second one is invalid without the first.
PeterL: http://btcbase.org/log/2018-01-06#1765616 << I dun see why patches have to change much? Thinking of the system proposed by mircea_popescu you would have one line change in a "patch version" file, the rest of the patch would be identical to what we have now ☝︎
ben_vulpes: also, single-file vpatches drives the system towards whole sourcetree hashing, otherwise they'll definitionally never depend on one another
phf: fwiw bulk of these tools have been written through the 90s and what was worthwhile from orcland was published that way then. until silent takeover by latex & 1.8gb tex installations happened and none of these tricks work anymore (because the necessary hooks are so deep within the layer of cruft it's near impossible to get to them, and one way they did it is through standard file system lay out, that requires a chain of compilation stages to move files

asciilifeform: this is an O(1) op in the file system
asciilifeform: this is mainly to build later for microcontroller that just has uart, no file system
mircea_popescu: geting hard numbers on file system performance, something everyone involved in data storage for the past 30 years has been vehehehery deliberately hiding, is certainly better use of time than, for instance, attempting to reason with djb jzw & all.
phf: it does an equivalent of patch, but without calling out to c programs and without the result (or intermediate steps) touching the file system at any point
erlehmann: every idiot who just takes an uploaded file and converts it using ffmpeg is just a 4 line text file away from me filling whatever storage the idiot has on the converter system

phf: writing out each one of those concerns separately will teach you how to do it (or whether it can even be done, like with "atomic file system")
asciilifeform: !~later tell Framedragger the table system can be easily prototyped , without writing any kernel code, by using 16G file on ordinary disk. (at the obvious speed penalty.)
thestringpuller: "RAND_poll seeds the random number generator using a system-specific entropy source, which is /dev/urandom on UNIX-like operating systems" << so openssl default is PRNG??? RE: "The urandom device may lack sufficient entropy for your needs, and you might want to reseed it immediately from /dev/random. On Unix and other operating systems that provide the block device, you can use RAND_load_file to load directly from /dev/random."

Framedragger: asciilifeform: on what does it run again? nfs as in network file system, or sth else?
asciilifeform: 'alf-wp' does not, and will not, because it does not have write permissions for the file system.
asciilifeform: 'BLATSTING's implementers are a big fan of mmap. It seems to be used for all file access, not just for manipulating kernel memory through `/dev/mem`. Is it done this way to reduce the number of system calls, to be less conspicious, as well as not reveal what exactly is accessed when running in `strace`? Or maybe a later stage of the rootkit blocks certain kinds of syscalls on certain "hidden" files.'

mats: how does anybody meaningfully build on e.g. 'msdos' when it has only one operating mode, is purposed for a 'single-task', and doesn't blow up when some level of the abstraction (that by any reasonable person could be reasoned as multi-task if it is to do anything useful, e.g, graphics, networking, file system access!!1) has a bug in it?

asciilifeform: really this is quite similar to everyone's file system.
ascii_field: 'In monolithic operating systems, a driver can write to any word of memory and thus accidentally trash user programs. In MINIX 3, when a user expects data from, for example, the file system, it builds a descriptor telling who has access and at what addresses.
