Parrot 4.4.0 "Banana Fanna Fo Ferret" | parrot.org | Log: irclog.perlgeek.de/parrot | #parrotsketch meeting Tuesday 19:30 UTC
Set by moderator on 15 May 2012.
dalek kudo/qbootstrap: cc75bfd | jnthn++ | src/core/Temporal.pm:
Twiddle whitespace around stub syntax; there's actually a bug lingering that causes this to be needed. This does mean we fully parse CORE.setting, though, just blowing up at CHECK time because something causes generation of calls to infix:<> in a few places.
 00:12
kudo/qbootstrap: dccd9cf | jnthn++ | src/Perl6/Actions.pm:
Avoid a double-make (but doesn't fix anything).
kudo/qbootstrap: d7e3797 | jnthn++ | src/Perl6/Actions.pm:
Apply a tweak also made in HLL::Actions last night; this clears up a vast number of the spectest failures as a result of switching to QRegex for parsing Perl 6 source. O(30) test files have failures that need investigating.

whiteknight good evening, #parrot 01:49
cotto 'evening, whiteknight 01:56
whiteknight hello cotto, how are things going with you? 02:13
02:15 JimmyZ joined
whiteknight Two things are really bugging me about this IO code 02:16
First is how inconsistent things are. Some APIs don't test that the filehandle is flagged to perform the correct operation, so in some cases you can write to a read-only handle or vice-versa
Second, all the buffering code assumes that a single buffer can be read and/or write, and every single operation has to test what mode the buffer is in 02:17
what does it even mean to flush a read buffer, or to fill a write buffer? It's nonsensical, but these are both supported operations
and what happens when we write data to a buffer flagged for reading? I don't know, but it is supported 02:19
and it also bugs me that the functions in src/platform/*/io.c are all named Parrot_io_*, as if they're in that subsystem 02:29
I think I'm going to rename the functions in src/platform/*/io.c, to be more clear about the low-level nature and avoid collisions on the more common shorter names 02:32
for instance, I would expect Parrot_io_seek to be the API seek routine, but that's actually the private low-level routine
benabik +1 02:33
whiteknight Those low-level routines are going to be renamed Parrot_io_internal_* instead, to be more clear 02:37
luckily, it doesn't look like we're exporting any of those, so it's a non-issue

tadzik so-so. I'm quite ill, and now lying down at home writing my C++ assignment

whiteknight good afternoon, #parrot 18:50
19:04 PacoAir joined 19:20 benabik_ joined
whiteknight it looks to me like the PIO_BF_LINEBUF (line-buffering) mode in master only operates on write operations, and is hard-coded to break lines on "\\n" 19:47
it looks like it's only effect is to force a flush if the written string contains "\\n" 19:49
compared to that small "benefit", the logic to set it up and manipulate and check for that flag in several places hardly seems worth the effort
moritz so, what happens when you remove it? you get block buffer when writing to a pipe? 19:54
19:55 lucian joined
whiteknight The only difference I see in the current system is that writes flush a little bit more often when line buffering is turned on 20:01
maybe there's more that I can't see, but that's the only difference I've found so far
sorear I think the idea is to make say "Hello, world"; sleep 20 DWIM
line-mode buffering on stdout by default is part of the common behavior expected of all unix languages 20:02
C has done this for decades
is it necessary? no comment 20:03
whiteknight I'm not against having a line-buffering mode, if it does something real and worth-while
but we have a significant number of lines of code dealing with setting, clearing and checking that flag, and not a lot of benefit from it 20:04
If all it needs is a way to tell certain handles to fsync all the time, that's something
but it doesn't even do that. It's only fsync'ing when we have a "\\n" character to be written, which seems awfully narrow 20:05
dalek nxed: 315204d | NotFound++ | winxedst (2 files):
rename subexp to subexpr in a bunch of places for consistency
 20:06
sorear my favorite copy of C89 says "standard output ... is fully buffered if and only if it can be determined to not refer to an interactive device" 20:08
but is silent on the question of whether stdout-to-a-tty should be unbuffered or line buffered by default 20:09
C99 says no more 20:12
POSIX.1-2004 also does not mandate line buffering support(!) 20:16
NotFound whiteknight: if the buffering gets separated from the handle, the buffer itself will take care without checking elsewhere, isn't it?
