* UTF-8 support for call.Thomas Osterried2016-02-112-278/+769
| | | | | | | | | | | | | | | | | | | | | Patch by Cathryn Mataga. 1. Now supports UTF8 or IBM850 as the encoding style over AX25. 1a. Attention was paid to make sure that wide characters worked with East Asian fonts. 2. Now the screen can be resized. correctly. The program no longer crashes when it is resized. 3. Added a scrollback buffer. Use the up and down arrow keys or the page up/page down keys to scroll through history. After the screen begins scrolling, press 'up arrow' to view history. 4. Many visual quirks have been fixed. This version is now dependent on iconv and wide character versions of ncurses, which I think should be everywhere these days.

* call: Fix race condition between select(2) and signal delivery.Ralf Baechle2015-06-101-6/+13
| | | | | | | | | | | | | | If a signal is delivered between the start of the main select loop and select might wait for a long time. Fixing this with select is not possible so switch to pselect. Unlike select pselect akes a struct timespec pointer as its argument so rewrite the related infrastructure to work with struct timespec instead of struct timeval. For now the race did only affect the SIGQUIT delivery. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* call: Harden against compiler overoptimization.Ralf Baechle2015-06-102-2/+2
| | | | | | | A compiler won't know that the interrupted variable can be changed behind its back in a signal handler so it might do clever overoptimizations. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* Call: Handle select(2) returning EINTR.Ralf Baechle2015-06-101-5/+8
| | | | | | | | | | | | | | This may happen when call is running in curses mode, and the terminal window is resized which results in a SIGWINCH sent. Ncurses as normally configured on Linux distributions will have installed a handler. If as it is the most likely case, the select call will be interrupted by the signal, select will return EINTR and call will exit. Note that this doesn't mean it's now a good idea to resize the window. Call will still not handle the screen size change properly and the output will look ugly and missformatted.

* bugfix: buffer overflow in call.c.Thomas Osterried2012-10-281-2/+2
| | | | | | | | | | | | If the call sign you connect to has 9 characters (i.E. DL9SAU-10), then call segfaults. idString in the ncruses mode routine start_screen() was dimensioned too short, and the auther had the fatal assumtion that a call is 8 characters long (and not 9), and he did limit the length in sprintf with ... %n.ns This is an old bug. Obviously, ubuntu 12.04 and 12.10 introduced better runtime checks into potential buffer overflows.
* Apply program name transformations also to man page content.Ralf Baechle2011-12-112-13/+30
| | | | | | For now these options are just honored for the call.1 and listen.1 man pages because these days these two programs generally get renamed to avoid naming conflicts with other programs.
* - Important bugfix (call did not work properly after my last patch)Thomas Osterried2009-11-112-140/+215
| | | | | | | | | - Better error handling on read() == -1 and write() == -1. Previously, the return value was not honored correctly - and could cause unexpected results. - New option "-R": Disable all remote commands like autobin (#BIN#), 7plus downloads, //echo, etc. This is useful for scripting where you just don't like the remote site to trigger uncaught conditions here.
* fix: on read through closed pipe, call did endless select(),Thomas Osterried2009-08-242-17/+66
| | | | | | | | read() = 0, wht consumed 100% CPU power. New options: -W: waits after EOF on stdin. Useful for scripting, for waiting for data coming via fd 3 (ax25 connection) -T secs: idle timout after secs seconds.
* Remove use of backwards compatibility header name.Ralf Baechle2009-06-211-12/+0
| | | | | | Glibc as old as 2.2 provides working headers under the right name and if not libax25 would install headers under the right name so this has become redundant and ugly.
* Ignore a few more generated files.Ralf Baechle2009-06-191-0/+1

* Remove all generated files.Ralf Baechle2009-06-191-522/+0
| | | | | | | | | | | | | | Keeping generated files in CVS doesn't only tend to produce large and cluttered files it also may result in build problems due to timestamps in the wrong order. So dump everything, update .cvsignore to ignore these files and resolve all warnings generated by autoreconf. From now on users of a CVS checkout should run the command autoreconf --install --force after having done a CVS checkout. For this to succeed automake, autoconf and libtool will have to be installed.

* on modern systems, the ncurses gui crash in wtouchln() orThomas Osterried2009-04-291-2/+3
| | | | | | | | | wnoutrefresh() [ncurses functions], called from winclose() in menu.c. Debunging with gdb showed that wtab->fline was a large negative number. Now doing better checking that wtab->fline and wtab->lline is > 0. Seems that this fix is sufficient. If it will come out that it is not, we'll write a wtouchln() wrapper which checks if the arguments are positive and reasonable small.
* fixed segfault issueThomas Osterried2009-04-151-10/+10

* call writes messages to stdout using printf(). it writes dataThomas Osterried2009-03-191-8/+33
| | | | | | | | | | | from the ax25 connection using write(0). everything was fine as long as call wrote to stdout. If instead we use output redirection to a file or stdout (> foo, | bar), then the messages like "Connected to.." appeared at the end of the connection. I guess it's a glibc issue that printf (whih is buffered) behaves different when stdout is redirected. Fixed using fflush() after each printf().

* major fix.Thomas Osterried2009-01-241-37/+101
| | | | | | | | | | | | | | 1. if a line was split over two ax25 packets, we read i.e. 1. "foobar told me" 2. " go7+. ". The second packet was interpreted like starting with " go7+. ". thus in a pure bbs listing it was misinterpreted as start of a 7plus file. Since the data was not like a 7plus header starts, the 7plus download parser caused a segfault (after copying i.E. 1555 bytes to char s[20]. [seen in gdb ;-] -> enforced a "linemode". 2. protocol and array size assurances in the #BIN and 7plus part, as well as in dupdstatw().

* - bugfixes:Thomas Osterried2009-01-211-57/+84
| | | | | | | | | | | | - fileupload (in raw and gui "slave" mode) goes only step by step the 128 bytes further if user enters a character. Thanks to Daniel DO8CD for the report. - write() returns -1 at EAGAIN (packet links are usually slower then linux file IO, and EAGAIN occurs because the txbuffer in the kernel is full). This lead to a bad substraction in sent bytes and thus to file corruption at the receiving site. - added more help: now explaining all the ~-Escapes in raw mode in the ~? command.
* - new option -S: be silent. useful for using call in shellscripts.Thomas Osterried2008-07-092-12/+32
| | | | | | - call was not usable as a pipe in scripts because it read 511 bytes, tried to write these 511 bytes (but 256 is max for ax25 I-frames), got -1 EMSGSIZE (Message too long) and terminated.
