2002-11-10 Werner Koch <wk@gnupg.org>
* assuan-pipe-connect.c (assuan_pipe_connect): Changed the order
of the dups to handle cases where we have already used fd 2 for
other things.
2002-10-31 Neal H. Walfield <neal@g10code.de>
* assuan-util.c: Include <ctype.h>.
(_assuan_log_print_buffer): Elide the magic numbers preferring the
standard isfoo functions. Use putc_unlocked where possible.
(_assuan_log_sanitized_string): Rewrite to use putc_unlocked and
the isfoo functions.
2002-09-05 Neal H. Walfield <neal@g10code.de>
* assuan-defs.h (_assuan_read_wrapper): Depreciated.
* assuan-util.c (_assuan_read_wrapper): Removed.
* assuan-defs.h (_assuan_write_wrapper): Depreciated.
* assuan-util.c (_assuan_write_wrapper): Removed.
* assuan.h (assuan_set_io_fun): Depreciated.
* assuan-util.c (assuan_set_io_fun): Removed.
* assuan-defs.h (_assuan_read): New function.
(_assuan_write): Likewise.
* assuan-io.c: New file.
* assuan-buffer.c (writen): Use _assuan_write rather than doing
the work here.
(readline): Likewise for _assuan_read.
* Makefile.am (libassuan_a_SOURCES): Add assuan-io.c.
2002-08-16 Werner Koch <wk@gnupg.org>
* assuan.h: Renamed Bad_Certificate_Path to Bad_Certificate_Chain.
2002-07-30 Werner Koch <wk@gnupg.org>
Changed the license from GPL to LGPL.
2002-07-23 Werner Koch <wk@gnupg.org>
* assuan-handler.c (_IO_cookie_io_functions_t): Define it here if
it does not exists.
2002-06-27 Werner Koch <wk@gnupg.org>
* assuan-pipe-connect.c (assuan_pipe_connect): No special handling
for the log_fd and stderr. Connect stderr to /dev/null if it
should not be retained.
2002-06-26 Werner Koch <wk@gnupg.org>

accidently print an extra LF.

instead of pth.

pth_accept - using the assuan included accept code would be a bad
idea within Pth so we don't need a replacement function.

2002-02-27 Werner Koch <wk@gnupg.org>
* assuan-client.c (assuan_transact): Add 2 more arguments to
support status lines. Passing NULL yields the old behaviour.

without using the data fp.
2002-02-14 Werner Koch <wk@gnupg.org>
* assuan-inquire.c (assuan_inquire): Check for a cancel command
