mainzelm a5e76d4484 Bug fix for let-match: variables may be #f. 2003-01-23 17:18:08 +00:00
sperber 4a1c23a9bb Fix a bug in SEND-MESSAGE:
There is such a thing as an empty datagram; SEND-MESSAGE used to
ignore those.  Now force those to be sent as well.
2003-01-21 09:47:10 +00:00
mainzelm c0cccd7c7a My first post 0.6.3 fix: md5 is not opened by default and you cannot
load it later since the path is not translated.
2003-01-16 16:52:51 +00:00
sperber 00e8147657 I did it again:
only multiply timeout by 1000 if it's a number.
2003-01-14 13:21:31 +00:00
sperber 32953f94c0 It had to happen: the first post-0.6.3 bug fix.
The SELECT* operations take a timeout argument, specified to be in
seconds.  Instead, they took milliseconds.  Fix this.

mainzelm 52c50f9410 Check whether the file is opened non-blocking and call read-block with
'immediate in this case.

mainzelm 804362834b Extend with-errno to capture all I/O exceptions of the VM:

+ capture os-error in with-errno-handler* and adjust exception
  arguments to fit errno-handlers

mainzelm edddbd2925 Partially rewrite of read-string(!)/partial:
- immediately return on vacuous request

- try to avoid copying in read-string!/partial

- don't use read-string!/partial in read-string/partial to avoid
  duplicate copying

- if argument is fd, set port-buffer to bufpol/none as usual

mainzelm b2f0570a86 + when importing scheme, hide the procedures which are about to be

  scheme) you can now use (open scheme-with-scsh).

+ removed superfluous partial-s48-ports
2002-11-19 12:16:08 +00:00
sperber 883117ae06 Change SELECT! in the same way as SELECT: only ask the buffers of
ports that were passed in, not those of raw file descriptors.
2002-11-12 14:26:02 +00:00
sperber a73f146a23 Change CONNECT-SOCKET to pass underlying file descriptor to SELECT to
prevent SELECT non-blocking because there's space in the buffer.
2002-11-12 13:14:44 +00:00
sperber a206e4f70a Change the semantics of select so that it doesn't check the underlying
port buffer for fdes arguments.
2002-11-12 13:13:27 +00:00
mainzelm 8900f05fd2 call select in connect only on EINPROGRESS, loop on other errors
(which should not happend anyway according to POSIX).
2002-10-31 09:51:48 +00:00
mainzelm bcd64a2b3a + Use select on socket:outport if connect returned EINPROGRESS.
+ Clearer return values for %connect: return a pair that indicates
  whether an recoverable error occured and if this error was EINPROGRESS
  or something else.
2002-10-30 13:12:00 +00:00
sperber 4290ccae21 Remove the Olinist CONDITITIONALS package, also fixing some atrocious
uses of whitespace, newline, and indentation.
This saves another 60k or so in scsh.image, actually getting us below
the level of 0.6.2.
2002-10-30 12:33:51 +00:00
sperber 20b65e6bfa Make dynamic sub-regexps of regexps involving repetition work. 2002-10-30 12:13:20 +00:00
sperber c7e49f9274 Rework CONNECT-SOCKET to use SELECT.
Note: this is presently broken because of a wrong input-port/output
port classification of the port passed into SELECT.
2002-10-30 12:01:19 +00:00
sperber d0977ea4d4 Revamped the SELECT implementation to properly distinguish between
input and output port.  Also, SELECT and SELECT! are no longer
squashed into one silly procedure.
2002-10-30 12:00:15 +00:00
sperber a8ad3e0c71 Cater to dynamic subforms of SUBMATCH. 2002-10-29 15:57:00 +00:00

eknauel d1142b703c - Support for odbc 1.0 alloc functions 2002-10-11 08:06:45 +00:00
eknauel 41d219a5c1 + define SQLLEN if not defined (libiodbc on OS X doesn't have it)
+ new (less, but still) broken version of SQLGetData()
2002-10-05 18:00:59 +00:00
eknauel ce96216d41 + This version introduces the all new SQLBindCol(), which might (in
contrast to former versions) someday be capable of returning things
  like SQL_TIME_STRUCT, SQL_DATE_STRUCT, SQL_TIMESTAMP_STRUCT and
  SQL_NUMERIC_STRUCT.
+ However, SQLGetData() is now even more broken than before (if used
  on integer columns). It seems, that I failed to understand the API
  reference on SQLGetData() completly!
2002-09-30 18:20:47 +00:00
eknauel dc07184b5d + support for SQLBrowseConnect()
+ finalizers for connection-handles, environment-handles
  and statement-handles

eknauel 4651284138 Fixed a braindead bug in odbc-sql-bindcol() buffer bookkeeping that
would raise an buffer-exceeded-error even if buffer_needed <
buffer_len after the buffer has been rebound
2002-09-24 13:48:20 +00:00
eknauel eb4b60db6f added a few comments 2002-09-24 13:29:24 +00:00
eknauel 7cc0537ed4 Basic support for using SQLBindCol() from Scheme. Reading integer
values from result set is broken. Unbinding columns is not implemented
yet.
2002-09-24 13:29:03 +00:00
sperber 938182d4b1 Fix the most obvious insanities that's to do with dynamic parts of the
RX syntax.  Namely, a lot of code (used to) assume(s) that the
total-number-of-submatches (TSM) quantity is static even for dynamic
regexps.

Specifically, RE-TSM now returns an unspecific value instead of 0 for
non-regexps which should break most of the code that used to just
silently do the wrong thing.  It's likely that more examples involving
dynamic sub-regexps will fail.

In the process, I also removed some of Olin's naming craziness (using
"%" signs to convey meaning) which I needed to do to halfway
understand what's going on.

- support for SQLColAttribute() (odbc_sql_col_attribute)
2002-09-12 14:31:31 +00:00
mainzelm 64d35131f3 Fixed a subtle bug in the macro for the << redirection: The port
opened by open-input-string could be closed by the GC before the exec().
Now << stores the port in a global variable.
The test to reveal the bug was:

(let lp ()
  (run (head) (<< "a"))
  (lp))

printing a "closed channel" message after some a few hundred interations.
2002-09-12 07:30:30 +00:00
eknauel 87846eef58 - support for SQLNativeSql()
- dynamic memory allocation for return values in these functions:
  - odbc_sql_get_info_string()

  - odbc_sql_get_stmt_attr_string()
  - odbc_sql_get_desc_field_string()

  - odbc_sql_get_data()
  - odbc_sql_describe_col()
  - odbc_sql_get_diag_recs()
- odbc_sql_data_sources() is still broken: sometimes the result string
  is truncated. I'm not sure if this not a unixODBC-bug...

eknauel 186f745306 - Fixed confusion of database-handles (which basically are
non-existent) and descript-handles.
- sql-datatype-* defintion for use with SQLGetTypeInfo() (odbc-sql-get-type-info)
2002-09-03 08:18:42 +00:00
eknauel 23151f3ad1 - Don't distinguish between SQL_SUCCESS and SQL_SUCCESS_WITH_INFO.
- Don't call SQLGetDiagRec() automatically on SQL_ERROR, some ODBC
  seem to have a broken SQLGetDiagRec() implementation. Let user call
  SQLGetDiagRec() from Scheme at his own risk.

The ODBC documentation thinks it's a good idea to call SQLGetDiagRec()
after each ODBC-call that might return SQL_SUCCESS_WITH_INFO. IMHO
this sucks. However it's now possible to do so in the user's Scheme
code.

sperber 6eb3a1b0cc Obsolete. 2002-08-20 14:22:33 +00:00
sperber 33c14d7901 First stab at implementing SELECT/SELECT!:
- extend the VM interrupts to distinguish between read and write
  events
- add new ADD-PENDING-CHANNEL instruction to the VM
- add WAIT-FOR-CHANNELS procedure to the run-time system
- implement SELECT and SELECT! on top of that in newports.scm

This runs some basic tests, but in general should be considered
largely untested.

Moreover, SELECT/SELECT! never detect any exceptional conditions---the
returned vectors are always empty.  This is because the VM doesn't
really track those, and it's unclear whether it would be worth the
effort.
2002-08-20 14:03:01 +00:00
sperber ac343ba970 Replace Martin's implementation of selective blocking by the one in
Scheme 48 1.0.1.

Namely, instead of associating a list of queues with every thread, we
associate a single cell, holding the thread.  That cell is stored in
thread queues, and once a thread is made runnable again, the cell is
set to #f.  The thread-queue accessors ignore cells containing #f.

Implement an experimental OBTAIN-LOCK-MULTIPLE to test the whole
thing.

All this hopefully preserving backwards compatibility.

sperber 4381ac9095 Add a whole bunch of S48_GC_PROTECT annotations in functions which

s48_extract_integer can cause a callback for bignums, and, hence, heap
allocation.

spurious failures in SET-FILE-TIMES.
