ave1: http://btcbase.org/log/2018-10-15#1863087, look at the pasted code. Yes, you move it from a dynamic allocation on the heap to a "dynamic allocation" on the stack. With the major advantage that the stack is a well defined mechanism with predictable results where dynamic allocations are not.
a111: Logged on 2018-10-15 19:13 bvt: ave1, can you expand on getting rid of string allocations? I see a way to get rid of it for Mode, but not for the Path argument. i can move its c-string from heap to stack, but that would be it. anyhow, i will revise this aspect.
ave1: Using the stack makes code less error prone and a lot more readable, please read the FFA code; http://www.loper-os.org/?cat=49.
bvt: thanks, i see what you mean. the Interfaces.C.Strings.New_String() comments explicitly say that the heap allocation is necessary for the large strings, which is not the case for vpatch temporary file names.
bvt: i have already reworked the code based on the following code from GNAT: http://p.bvulpes.com/pastes/xjjec/?raw=true (g-locfil.adb, lockfile implementation). i.e. System.Address of an aliased String as argument to C function.

mircea_popescu: yknow it occurs to me, one could make a likely very popular film, call it "captive" or w/e, simply through filming the male seminal canal from teste to ligature point in one of those tube-tied doods. 4 minuites of voice-over at the beginning explaining what's what ("this is joe. joe is a sperm." bla bla) and then the rest of an hour and a half just... let people watch the random walk.

mircea_popescu: http://btcbase.org/log/2018-10-15#1863111 << thinking about this in the interim, it is EVIDENTLY the case. "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.
a111: Logged on 2018-10-15 19:24 mircea_popescu: s a file system AT ALL, and the "all things are files" is just a thin wraper on a turd sausage made out of "we have no data model beyond ram and our disk doesn't actually work".
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 ?
mircea_popescu: in any case there's no such thing as a filename anywhere at all, it's not even 2nd class, it's a sort of indian.
mircea_popescu: and obviously most of the reason the sql flavour is broken is because "oh, structure could never be aforeknown" and so "must have maximal hallucinatory freedoms".
mircea_popescu: "then you want to put these '''maximal freedom''' elements in a tree ?" "it's not a tree, it's a '''directory structure'''." "wtf is that ?" "a half-baked tree." "you're really dedicated to this half-baked thing beyond all else, aren't you ?"
mircea_popescu: what fucking filesystem. halfbakedsystem more like it.
mircea_popescu: man-drive dialogue flows always like : "i want file X" "wtf is that ?" "tell me what i told you before file X is supposed to be" "bytes 4978459876 through 50987498098" "i want bytes 4978459876 through 50987498098 please" "here you go" "are these file X ?" "fuck you" "does file X even exist ?" "little bitch..." "grep -a -C 500 'known pattern' /dev/sda | tee /tmp/recover"
asciilifeform: http://btcbase.org/log/2018-10-16#1863191 << bonus: nobody actually sells a hdd that's 'byte device', they're addressable in 512byte blox ( and internally with 4096byte flash sectors ) and it actually makes a diff , not only in re speed but the life of the iron ( erry sector can be written ~2000 times )

lobbesbot: asciilifeform: The operation succeeded.
asciilifeform: diana_coman: if my nitpick isn't clear, i can post an example later today.
asciilifeform: http://btcbase.org/log/2018-10-16#1863198 << yes fs is a 1960-style db, i thought this was obvious

asciilifeform: a http://btcbase.org/log/2018-10-15#1863136 - machine needs no predefine fs, you can use whatever data structures you like and they'll still be there when the power is cycled, per http://www.loper-os.org/?p=231 formula.
a111: Logged on 2018-10-15 19:34 asciilifeform: for instance 1 possible answer is 'no files, errything is an s-expression, and names live in gns'
asciilifeform: the fs as we know it is a classic example of 'plugging funnel at wrong end'.
diana_coman: asciilifeform, good point; answered
asciilifeform: when disk was refrigerator-sized, its write speed was 100kB/sec, and ram cost 1 toyota per 128kB, in 1980, it made sense to ask operator to manually move data structures to/from disk/ram. imho today it does not. run in ram, persist it to flash when power cuts out , running from supercap.
asciilifeform: ohai diana_coman
diana_coman: it might really be that my ada-fu is not up to the task yet
asciilifeform: diana_coman: dun worry, it will make sense very quickly when you bake the record
diana_coman: I expect /hope so; meanwhile it's very good to have that observation there, thank you!
asciilifeform: diana_coman: didja ever look at my 'nqb' example ? it has buncha records , that get serialized/deserialized correctly
asciilifeform: ( some components -- 'manually', as shitoshi used wildly variable sizes; some -- cleanly )
diana_coman: I did; and I will re-visit it
diana_coman: at any rate when I get to the records I might come and whine loudly if I get stuck
asciilifeform: diana_coman: you won't need to do any of the streams horror that i did there, because those of your subfields that are arrays, have strictly bounded sizes
diana_coman: thing is: there are lots of this "int8 number of keys" followed by "n*int8 key ids" and this in turn is just part of the wider thing
asciilifeform: diana_coman: if you get stuck i'ma show you how to make it go, cleanly, i have a working example of nearly the same thing you're doing ( gossip prototype thing ) that simply hasn't been cleaned for publication of yet
asciilifeform: same proggy i took the udp lib from
BingoBoingo: hanbot: ty
diana_coman: noted, thank you
asciilifeform: of all the various items asciilifeform has used over the yrs, ada ( and not even 'modern', but even back in ada-83 ) has the absolute sanest support for strict record layout that actually worx as described
asciilifeform: kinda like cl's 'binary-types' thing, but as part of the language, rather than add-on hackolade
asciilifeform: it was one of the items i saw back in '16 and thought 'hmm'
diana_coman: and added for clarification re converters since it struck me that it might be unclear there what's all about: http://ossasepia.com/2018/10/16/smg-comms-chapter-2-raw-types/comment-page-1/#comment-4341
asciilifeform: diana_coman: this is correct, i think you grasped it
diana_coman: that was my whole point of the separation between layer 0 and layer 1 there: at 0 everything is just an array of octets, nothing more
diana_coman: anyway, when I get to the data structures, I'll see re serializing
asciilifeform: diana_coman: aha; you dun actually need to shovel raw octets anywhere other than the udp transceiver
asciilifeform: back when i wrote in c, i also serialized/deserialized 'just once', when casting packet to the correct struct, but to precisely nail down the latter required gcc-specific pragmas, as c per se does not give this ability. but in ada the required knobs are standard.

diana_coman: it is!
mircea_popescu: anyway, those int8, nint
mircea_popescu: things are kinda deliberately made to dovetail with ada, so i hope they do and if they don't we fix.
diana_coman: kk; I'll keep up this approach of published-even-if-stumbling small steps so on one hand there is something concrete to shoot down if needed and on the other hand we can correct any trouble early on, hopefully
mircea_popescu: sounds like the perfect plan

BingoBoingo back from paying the rent, pretty sure they eyes managed to get a bit of sunburn in spite of sunglasses
diana_coman: o.O how do eyes get sunburn BingoBoingo ?
diana_coman: BingoBoingo, also, "comminsion" in the most recent qntra title?
asciilifeform: cornea burn ?
asciilifeform: BingoBoingo has all-natural eyes, no glass
asciilifeform: ( possibly the 1 win from wearing glasses, is the uv filter coat... )
BingoBoingo: Well, in this southern hell afternoon walks may lead to a bit of a headache. It increases in intensity and seens to be centered around the eyes.
asciilifeform: mno then not this, no headache from cornea burn, just 1 hell of an itch and quicker cataract
BingoBoingo: asciilifeform: I did wear the UV filters today
asciilifeform: then what ails you is old-fashioned heat stroke, drink water
BingoBoingo: That could be it
BingoBoingo: diana_coman: ty, fxd
diana_coman: BingoBoingo, second asciilifeform there: it does sound like heat stroke really; cover your head
BingoBoingo: Natural headcover still intact
diana_coman: I can say the same, but honestly, it was never enough protection against the sun (and fwiw I have thick hair anyway)
diana_coman: anyways, each with their own head
asciilifeform: when i was in BingoBoingostan, found myself on numerous occasions wishing for cork helmet.
asciilifeform: but interestingly 0 sunburn, in asciilifeform's experience sunburn seems to exist only in usa..
diana_coman: ahahah; well, I did get sunburn on my shoulders in Costa Rica but mainly because of being in the water most of time while at the beach
BingoBoingo has met a number of not entirely white Brazillians who managed to pick up profound beach sunburn

diana_coman: I can easily picture that really; at any rate, I got otherwise at least 2 shades darker after the few days by the ocean and even now (so...2 months later) I'm still darker than my natural shade
BingoBoingo: My arms and legs manage to tan to darker shades with sun exposure, but my face pretty much constantly stays in a state of more or less accute sunburn regardless of the quantity and frequency of "bloqueador de sol" applied
Mocky: BingoBoingo, usually by the end of winter I look like a coffee with too much cream, but slightly too much summer sun and I turn into kunta kinte for 6 months
BingoBoingo: Mocky: That sounds rather healthy. My face and ears have taken to the color red as a seemingly permanent part of their color palette
BingoBoingo: Mocky: How is Qatar feeling? Does it feel normal yet?
BingoBoingo: ATTN: Over the next few weeks I will be making some fairly big changes to the Pizarro website (theme chopping, pictures, etc) If the pizarro site is broken and stays broken please let me know.
