Abdulaziz Ghuloum 53905b9eea Changes from Derick Eddington supporting file system info: 
- Added file-regular?, file-directory?, file-symbolic-link?,
  directory-list, make-directory, delete-directory, change-mode, 
  and make-symbolic-link.

- Bug fix in ikrt_open_input_fd and ikrt_open_output_fd which
  considered a 0 FD as an error.

- Bug fix in ikrt_getcwd about len+1.

- Bug fix of &i/o-file-protection which didn't have &i/o-filename as
  its parent.

- There is a new src/ikarus-errno.c file.  

- Made tcp-connect and friends tell when they "failed to resolve
  host name or connect".

- To support the uses of &i/o-filename subtypes, I modified
  print-condition so it will cleanly print the parents' fields of a
  condition;

Abdulaziz Ghuloum 66d085713f Made interrupted conditions &serious so that you can interrupt R6RS 
scripts.

Abdulaziz Ghuloum f6e5e4d5b4 Added -m32 to CFLAGS/LDFLAGS, updated copyright dates and version no. 2008-01-29 00:34:34 -05:00
Abdulaziz Ghuloum 64dac92831 Added tcp-connect-nonblocking which is line tcp-connect but puts the 
socket in nonblocking mode.  An operation that would block now
raises (continuable) a condition of type &i/o-would-block which
contains the port in question.  There's no way to handle the
condition gracefully yet.

Abdulaziz Ghuloum 0e38534d2e New IO layer is installed. Still buggy in some area but can be used 
for bootstrapping at least.

Abdulaziz Ghuloum c6b66f8661 Added a system library (ikarus system interrupts) that exports: 
make-interrupted-condition and interrupted-condition?
 2007-11-19 16:50:31 -05:00
Abdulaziz Ghuloum 79d529b224 Much improved error reporting when a library is not found. 
Example:

> (import (a b c))
Unhandled exception
 Condition components:
   1. &error
   2. &who: expander
   3. &message: "cannot locate library in library-path"
   4. &library-resolution:
       library: (a b c)
       files: ("./a/b/c.ss" "/Users/ikarus/.opt/lib/ikarus/a/b/c.ss")
 2007-11-19 02:46:45 -05:00
