Gauche fails to build on FreeBSD/i386

Vitaly Magerya — 2012-05-23T13:24:14

Hi, folks. I'm trying to build Gauche 0.9.3.2 on FreeBSD, and while
it works fine on amd64 (e.g. passes all tests [1]), it fails on i386
either like this (full log at [2]):

../../src/gosh -ftest ../../src/precomp -e -P -o gauche--collection ../../libsrc/gauche/collection.scm
Deallocating excessively large block.  Too large an allocation?
*** Signal 6

Or prints many error messages like this:

../../src/gosh -ftest ../../src/recomp [..stuff..]
GC Warning: Out of Memory! Heap size: 4 MiB. Returning NULL!
out of memory (2693136576).  aborting...

... and then:

../src/gosh -q -I../src -I../lib -lgauche-init ./extract -en -o gauche-refe.texi ./gauche-ref.texi
gosh: "error": Compile Error: Compile Error: Compile Error: Compile Error: cannot find "util/match" in ("../lib" "../src" "/usr/local/share/gauche/site/lib" "/usr/local/share/gauche/0.9/lib")
"../lib/gauche/condutil.scm":36:(define-module gauche.condutil (use  ...
"../lib/gauche/regexp.scm":106:(define-condition-type <regexp-inval ...
"../lib/gauche/parseo

test sometimes fails,maybe increase number of retries?

Hi.
I testing $ macro.

I thought $ is "compose" , but result is different.
I mean:

0.9.3 build fails if you specify sjis or eucjp to --enable-multibyte

If you compile utf-8 version, you probably don't need to update.

Release 0.9.3

Shiro Kawai — 2012-05-10T07:21:39

Gauche 0.9.3 is released.
Two big changes are (1) lazy sequences/generators and
(2) Windows native thread support.

Detailes release notes are on the webpage:
http://practical-scheme.net/gauche/index.html

For the next release, I aim at adding features for R7RS.

stream question / unbound memory?

2012-01-26T10:33:50

Hi,

why does the following example seem to need unbound memory?

sh$ { cat << EOF
#!/bin/sh
#|
GC_PRINT_STATS=1
export GC_PRINT_STATS
exec gosh -- "\$0" "\$< at >"
|#

(use util.stream)

(define (main args)
  (stream-for-each (lambda(x)
                     (write x)
                     (newline))
                   (port->stream (current-input-port) read))
  0)
EOF
} > test.scm \
&& chmod +x test.scm \
&& seq 10000000\
|./test.scm 2>&1 > /dev/null \
| grep --line-buffered heapsize |cut -f 2 -d ">"

output should be something like:
heapsize = 262144 bytes
heapsize = 786432 bytes
heapsize = 2502656 bytes
heapsize = 3338240 bytes
[...]
heapsize = 44535808 bytes
heapsize = 44535808 bytes
heapsize = 59383808 bytes

Thinking again about parameters in the VM

Kirill Zorin — 2012-01-14T03:52:51

"[An] error happens when a parameter is created *after* some
threads are already running, and the parameter is used
in those threads that were already running.  One possible
scenario is like this:

- We have thread A and thread B running.
- Thread A calls (use rfc.http) for the first time.
 This loads http.scm and creates parameters.
 Thread B isn't aware of those parameters.
- Thread B *dynamically* loads some file, say, foo.scm,
 which contains (use rfc.http).  This time http.scm has
 already been loaded, so it's no-op.
- Thread B calls some function defined in foo.scm,
 which in turn makes http call.  The call accesses
 parameters defined in http.scm, but they are not
 visible from B, hence the error.

This won't happen typically, since usually the modules
used by the program is statically stated in `use' form;
so when a thread starts running, all the necessary parameters
are already created.

However, if a module is dynamically loaded (via explicitly
by 'load', or implicitly by autoload), the above scen

copy-bit-field buggy?

Sascha Ziemann — 2012-01-12T13:10:57

The function copy-bit-field from srfi-60 seems to be buggy.

This is what SCM does:

"1111"
"111"

And this is what Gauche does:
$ gosh -u srfi-60
gosh> (number->string (copy-bit-field #b1000 -1 0 3) 2)
"1000"
gosh> (number->string (copy-bit-field #b0000 -1 0 3) 2)

DBI example

2011-12-22T09:04:02

First: is this the right mailing list for user questions?

If so:

I tried the DBI example from the reference documentation and get the
following error:

*** ERROR: list required, but got #<<mysql-result-set> 0x9b69fa0>

After some further reading I found the collection framework.

For newbies like me it would be useful to add the use statements at
the top of the example:

(use dbi)
(use gauche.collection)

unchecked FD_SETSIZE in fdset operations

Tomas Stanek — 2011-12-20T19:16:00

Hi,

code in libsys.scm and port.c uses FD_SET, FD_ISSET and friends on 
fdset. It however doesn't check if the descriptor in question is 
smaller then FD_SETSIZE. This in my case results in a segfault of 
the interpreter. I'm not including the fixing patch because the fix 
is rather trivial.

Best regards,
Tomas Stanek

calling (cgen-precompile scm-file :ext-initializer#t) multiple times

2011-11-06T16:21:58

Hi,

using gauche < 0.9.2 i could call
(cgen-precompile scm-file :ext-initializer #t)
multiple times in a row getting expected output

testing with 0.9.2 i found it somehow kept some state (list of modules)

i am not sure wether this is a bug or a feature

as workaround at the moment i use: (maybe shortest explanation to
understand my problem)

;; hackish workaround for bug? in gauche 0.9.2
(when (not (null? (all-tmodules)))
   (class-slot-set! (with-module gauche.cgen.precomp (current-tmodule-class))

0.9.2 is out

Shiro Kawai — 2011-08-06T13:24:20

Gauche 0.9.2 is released.  Check out the homepage for release notes.

http://practical-scheme.net/gauche/

I thought I made lots of changes, but overall, this is rather
a minor enhancement release with lots of small bug fixes.

One notable improvement is that we switched from NSIS to WiX 
to create Windows installer.  NSIS version was *.exe file
and some heuristic virus checker misidentifies it as a trojan
horse.  It also had a problem that it could smash the value of
PATH if it was too long.  I hope those issues are gone with
this new package.

Gauche-gl is also updated, for it fails to compile with 0.9.2.
Its feature hasn't been changed.

Is 'read' a security problem?

Lasse Kliemann — 2011-07-03T10:19:39

A client sends commands to a server as a series of s-expressions. 
The server uses 'read' to collect them. Is that already a security
problem?

The server does *not* use 'eval' but dissects the read 
expressions by itself. So that should not be a problem, as long 
as I do not make a mistake.

But what about special syntax, like sharp syntax? I have come so 
far to realize that I can introduce potentially dangerous 
elements using 'define-reader-ctor', so I will avoid that.

Am I on the safe side then?

If not, is there a kind of '(read :safe? #t)' that will ignore 
all kinds of "active" content provided by the client?

Thank you very much!
Lasse

Gauche logo merchandise?

Benjamin L. Russell — 2011-06-01T05:55:47

It would probably be fun to be able to purchase Gauche logo merchandise
(T-shirts, sweatshirts, mouse pads, mugs, etc.), similarly to, say,
Haskell logo merchandise (see "Merchandise - HaskellWiki" at
http://www.haskell.org/haskellwiki/Merchandise).

CafePress.com (see http://www.cafepress.com/) manufactures and sells
custom logo-related merchandise; it even features an online design tool
with the ability to upload images.  Basically, besides basic ordering
information, all that is needed to create a custom design product is a
logo.

Such merchandise could also be helpful for attracting attention to
Gauche and expanding the number of users.

I would definitely be interested in Gauche-related merchandise.  Would
anybody else also be interested?

"Gaucheプログラミング(立読み版) - Karetta" site is down

Benjamin L. Russell — 2011-05-20T11:02:59

Today I just installed Gauche-mingw-0.9.1 on a different computer from
before, and tried to start writing a small application in it, but when I
tried to read your online book "Gaucheプログラミング(立読み版) -
Karetta" ("Gauche Programming (Browsing Edition) - Karetta") (see
http://karetta.jp/) for reference, to my dismay, the service was down,
effective March 13, because of the recent earthquake!

My apartment in Tokyo is extremely cramped, without sufficient table
space to read a book and type on a computer at the same time, so I would
very much prefer to read an on-line version if at all possible.

I also tried to install "Gauchebox-0.9.1-box1.exe", which installs
sample code of the book _Programming Gauche_, but according to the
section entitled "Windows Binary Installer" on "Gauche - A Scheme
Implementation" (see http://practical-scheme.net/gauche/download.html),
the package is still "in preparation."

Is there any way to read an on-line book about programming in Gauche?
Ideally, if there were
