2021-11-10Move two BIGNUMs in printnumber() from the stack to the heap toTheo Buehler
prepare bc(1) and dc(1) for opaque BIGNUMs. "looks sane" otto
2021-03-08Add some references, most of these were removed when we stopped buildingJonathan Gray
and installing USD/SMM/PSD docs. jmc@ agrees with the direction, ok millert@ on an earlier diff

2017-11-27Safer handling of the jump_table[] in dc's bcode.cTom Cosgrove
Based on a diff sent to tech@ by kshe59 (at)zoho (dot) eu - thanks ok otto@, who also remembered to check the regression tests
2017-02-26Move away from BN_zero, the one returning an int is deprecated and theOtto Moerbeek
new one is a void function. From Daniel Cegielka.
2017-02-23Introduce e command, equivalent to p, but writes to stderrOtto Moerbeek
2016-12-10replace all references to bn(3) with BN_new(3),Ingo Schwarze

2016-07-17getopt(3) can be called twice (once for bc and once for dc), so reinit getoptOtto Moerbeek

2016-03-27some style(9) and redundant tests for NULL, from Michael W. BombardieriOtto Moerbeek
2015-11-03Surround pledge calls with blank lines.mmcc
2015-10-10Rather than invoking fork/execve of dc(1) on a pipe, compile in the dc(1)Theo de Raadt
code directly and use it as a subfunction. This refactoring allows use of pledge "stdio rpath proc tty" in the main bc(1) process before fork, pledge "stdio rpath tty" after fork, and fully reduced to "stdio" in the dc(1) child. This requires two recent to the kernel code (allowing sigsuspend(), and kill() self as pid 0). ok otto
2015-10-09Change all tame callers to namechange to pledge(2).Theo de Raadt
2015-10-03Now that dc(1) no longer supports !command with popen(), we can startTheo de Raadt
off with tame "stdio rpath". Once the (optional) file is opened, a further drop down to tame "stdio" works.
2015-10-03delete documentation for ! commandTheo de Raadt
2015-10-03disable ! command, makes dc(1) more tameableOtto Moerbeek
2015-02-16Include bn.h and err.h from <openssl/...>, not the old <ssl/...> location.Jeremie Courreges-Anglas
Remove unneeded ssl.h includes. Also built-checked against openssl-1.0.1e. ok otto@

from Sebastien Marie
2014-10-08userland reallocarray audit.Doug Hogan
Replace malloc() and realloc() calls that may have integer overflow in the multiplication of the arguments with reallocarray(). ok deraadt@
2014-05-20Use errc/warnc to simplify code.Philip Guenther
Also, in 'ftp', always put the error message last, after the hostname/ipaddr. ok jsing@ krw@ millert@
2012-11-07fix fractional number exponentiation, especially for negative exponentsOtto Moerbeek
2012-11-06use BN_set_negative() and BN_is_negative() instead of subtracting orOtto Moerbeek
comparing to zero
2012-11-06For exponenttion, only warn if the fractional part of the exponentOtto Moerbeek
is non-zero and avoid div by zero. Prompted by Andres Perera.
2012-08-19Stefan Unterweger pointed out that, contrary to the man page,Jason McIntyre
dc exited after processing any expressions and/or files; this is the doc fix, as requested by (and ok) otto
