* grdc(6): implement timeout with alarm(3)cheloha2020-06-061-11/+18
| | | | | | | | | | | | | | | grdc(6) has an optional argument indicating a timeout in seconds. For example, one could do: $ grdc 60 to to tell grdc(6) to run for sixty seconds and then exit gracefully. As implemented, however, the timeout may occur too early or too late if the system clock is reset with settimeofday(2). To avoid this problem we can instead use alarm(3) and a signal handler to implement the timeout. alarm(3) is unaffected by settimeofday(2).

| | | | | | | | | | my screen. i don;t have a copy of this book, and a brief search online shows conflicting punctuation, but i've chosen to replace the comma splice with a full stop, which is at least grammatically correct, and seems the most likely solution. whether this quote needs to be in two files escapes me...
* Be more specific regarding which encoding this simulator generates:schwarze2019-09-081-5/+7
| | | | | | | | | | | | | the existing text encouraged the misconception that punched card encodings were somehow standardized, which they were not. Lots of different encodings existed, and the one simulated here was a proprietary one of one specific vendor (GE). Also correct the history: the folks at Bell Labs already played with this. HISTORY mistake noticed by Sevan Janiyan <venture37 at geeklan dot co dot uk>, who also agrees with the final patch. tweak and OK jmc@

| | | | | | | | | | | | properties for the Wumpus. The bug has been present since 4.3BSD-Reno and was introduced by Keith Bostic on February 14, 1990 when committing the major rewrite from Dave Taylor. Patch (accompanied by a detailed functional and historical analysis) from David Fifield <david at bamsoftware dot com> on bugs@. With all the bats in these caves, how could a bug possibly survive for twenty-eight years?
* More fixes from David Fifield:tb2018-10-161-44/+50
| | | | | | | | | | | | | | | | | | | First, fill a missing pixel in the glyph for 'U'. Second, fix an off-by-one in the line output routine. This caused an extra space character to be output at the end of every line. It might have caused a buffer overflow if any glyph had used the entire possible width of 132 pixels, but as it is the widest is only 124 pixels. Third, output blank lines instead of lines full of spaces (the number of spaces was equal to the width of the most recent non-blank line). Finally, add bounds checks to protect against buffer overflows that could arise in case the data table were ever modified to draw out of bounds (characters wider or taller than 132 pixels, or a two-byte code where the second byte is past the end of the table). ok bcallah
