negative indices in array ranges
by Martin Baehr 14 Aug '26

14 Aug '26

hi, instead of having to do: reverse(reverse(foo/"/")[1..]); i'd very much prefer: (foo/"/")[..-2]; are there any reasons that speak against supporting this other than me not being able to offer a patch? greetings, martin.

levels might possibly be from -1 and up, -1 meaning infinite.

pike_frame->fun = FUNCTION_BUILTIN
by Arne Goedeke 16 Apr '26

16 Apr '26

In INIT, EXIT and some gc callbacks the fun in Pike_fp is set to FUNCTION_BUILTIN. there are some places in the code (e.g. ADT.List()->_get_iterator) where ->fun is used in INHERIT_FROM_INT et al, which segfaults (except with PIKE_DEBUG). I am not sure where to fix this. Should the *_FROM_INT macros check for FUNCTION_BUILTIN or is this better to be handled in the individual INIT/EXIT methods ? does anyone object to making ADT.Stack and ADT.Queue inherit ADT.List? arne

managing comport settings in linux
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 10 Apr '26

10 Apr '26

Not a good idea; the design philosophy of Pike is that Pike-level code should never be able to cause memory corruption at C-level. With ioctls there's no way to know what data a specific ioctl wants without reading the documentation for that specific ioctl for that specific OS. ioctls and fcntls are a way for device handlers to hook in APIs that aren't standard across all filedescriptors. / Henrik Grubbström (Lysator) Previous text: >2004-08-17 13:32: >Subject: managing comport settings in linux >-------------------------------------------------------------------- >What would be nice, is a way to define ioctl methods in >Pike.

Re: Playing music using pike and SDL.

Were you not able to get any C code to play through SDL either? Does your SDL library have a mixer compiled in it (I think it is optional)?

It's entirely possible there's code in the wild depending on the misspelled version though. Might be worth adding the correct one and leaving the existing one as a deprecated alias for it. ChrisA

bufferdAmount or bufferedAmount?
by ceder (-) Per Cederqvist ＠ Pike (-) developers forum 19 Nov '21

19 Nov '21

This code in lib/modules/Protocols.pmod/WebSocket.pmod seems to be missing an "e": //! @decl int bufferedAmount //! Number of bytes in the send buffer. int `bufferdAmount() { return sizeof(out); } I guess it should be "bufferedAmount", not "bufferdAmount"?

compile of pike under chroot failing

hi i'm currently building rpms of pike 8.0 for fedora35 and have troubles to "install" the binaries. my setup: mock (chroot environment for building rpms). inside of that environment there are several steps, mainly extract source-files, prepare, compile, install and collect the final binaries. the install step for both x86_64 and aarch64 seems to stop at: Executing(%install): /bin/sh -e /var/tmp/rpm-tmp.bdeWDr + umask 022 + cd /builddir/build/BUILD + '[' /builddir/build/BUILDROOT/pike80-8.0.1116-1.fc35.aarch64 '!=' / ']' + rm -rf /builddir/build/BUILDROOT/pike80-8.0.1116-1.fc35.aarch64 ++ dirname /builddir/build/BUILDROOT/pike80-8.0.1116-1.fc35.aarch64 + mkdir -p /builddir/build/BUILDROOT + mkdir /builddir/build/BUILDROOT/pike80-8.0.1116-1.fc35.aarch64 + cd Pike-v8.0.1116 + buildroot=/builddir/build/BUILDROOT/pike80-8.0.1116-1.fc35.aarch64 + rm -rf /builddir/build/BUILDROOT/pike80-8.0.1116-1.fc35.aarch64 + cd build + /usr/bin/make buildroot=/builddir/build/BUILDROOT/pike80-8.0.1116-1.fc35.aarch64 install 'INSTALLARGS=buildroot='\''/builddir/build/BUILDROOT/pike80-8.0.1116-1.fc35.aarch64'\'' lib_prefix='\''/usr/lib64/pike80'\'' include_prefix='\''/usr/include/pike80'\'' --traditional' Makefile:478: warning: ignoring prerequisites on suffix rule definition Makefile:524: warning: ignoring prerequisites on suffix rule definition make[1]: Entering directory '/builddir/build/BUILD/Pike-v8.0.1116/build' Makefile:478: warning: ignoring prerequisites on suffix rule definition Makefile:524: warning: ignoring prerequisites on suffix rule definition make[1]: Leaving directory '/builddir/build/BUILD/Pike-v8.0.1116/build' make[1]: Entering directory '/builddir/build/BUILD/Pike-v8.0.1116/build' Makefile:478: warning: ignoring prerequisites on suffix rule definition Makefile:524: warning: ignoring prerequisites on suffix rule definition make[1]: Leaving directory '/builddir/build/BUILD/Pike-v8.0.1116/build' Installing Pike in /builddir/build/BUILDROOT/pike80-8.0.1116-1.fc35.aarch64/usr, please wait... i'm waiting for several hours (around 16) now attaching with strace to the running pike gets me: close_range(11, -1, 0) = -1 EPERM (Operation not permitted) openat(AT_FDCWD, "/proc/self/fd/", O_RDONLY|O_DIRECTORY) = 9 getdents64(9, 0x7ffdc355bb80 /* 13 entries */, 1024) = 312 getdents64(9, 0x7ffdc355bb80 /* 0 entries */, 1024) = 0 close(9) = 0 close_range(11, -1, 0) = -1 EPERM (Operation not permitted) openat(AT_FDCWD, "/proc/self/fd/", O_RDONLY|O_DIRECTORY) = 9 getdents64(9, 0x7ffdc355bb80 /* 13 entries */, 1024) = 312 getdents64(9, 0x7ffdc355bb80 /* 0 entries */, 1024) = 0 close(9) .... fast looping over that lines any ideas? the same under fedora 34 built correctly. any suggestions? yours josef
