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

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)?

Pike 8.0.528 release candidate
by Peter Bortas 12 May '18

12 May '18

As is tradition a release has been prepared at the new years party with Champagne in one hand and keyboard in the other waiting for the clock to hit 24:00. Pike 8.0.528 release candidate: https://pike.lysator.liu.se/pub/pike/beta/8.0.528/Pike-v8.0.528.tar.gz Other builds: https://pike.lysator.liu.se/pub/pike/beta/8.0.528/Pike-v8.0.528-Darwin-15.4… https://pike.lysator.liu.se/pub/pike/beta/8.0.528/Pike-v8.0.528-win32-oldli… Real Mac build comes when Bill has time to have a look at that. Changes since Pike 8.0.498 (release 11) ---------------------------------------------------------------------- New Features ------------ o Sql.pgsql - Added support for PostgreSQL 10's stronger password authentication (SCRAM-SHA-256). - Slightly reduced overhead. - Support IEEE binary float database-wireformat. - Prevent new queries from starting in the local_backend. o Crypto.Hash.SCRAM New class to support SCRAM authentication. o Thread.ResourceCount New module to allow threadsafe race-condition-free counting of resources. o SSL.File Support query_fd() and set_buffer_mode() methods. o Toole.Standalone.check_http - Allow redirect responses. - Support --expect option. Bug fixes --------- o Compiler Improved variant robustness. o Calendar Updated tzdata to 2017c. o Crypto.CCM Fixed initialization of the iv. o Filesystem.Monitor - Fixed issue with next_poll being set to zero causing polling every second. - Fixed indexing the NULL value error when InotifyMonitor was used in combination with a filter_file() that doesn't accept everything. o HTTPLoop: Fixed some potential race conditions. o Image.Image - Improved argument checking in apply_curve(). Non-integer array values lead to use of uninitialized curve values. o Image.PVR Fixed size check for twiddled images. o MIME Support trailing newline in MIME part epilogues. o Protocols.HTTP Fixed incoming chunked transfers (timed async works now, chunk options are properly 'parsed'). o Protocols.LDAP Fixed race condition on initializing LDAPS. o Search.Utils Updated debug string format. o Sql.pgsql - Suppress spurious 'File not open' blurts on stderr when the connection is still pending and we inspect the connection object. - Signal EOF early before closing the SQL result portal and thoroughly cleanup bufcon/stashcount to prevent occasional deadlocks on asynchronous object destructions. - Suppress rare "access in destructed object" messages. - Rip out fundamentally flawed reconnect logic, made failures consistent. - Repair SSL connect logic. - Update documentation. - Repair fetch_row_array(). o mktime/System.TM Make timezone management consistent (especially UTC handling). o Standards.IIM Disabled debug output for unknown segment markers. o Stdio.send_file Improved support for TLS/SSL; wait for TLS handshake to complete before calling the sendfile done callback when sending an empty string. This fixes the issue where the connection got closed before TLS handshaking was completed, confusing the other side. o Image Creating images with mode "grey" now works as documented, e.g. Image.Image(10,10,"grey",123); Optimizations ------------- o mktime/System.TM Considerable speedup and a reduction in codesize. Building & Tools ---------------- o Image.SVG Fall back to using the unprefixed pkg-config if the arch-prefixed doesn't exist. o Mysql Support MariaDB 10.2 headerfiles. o precompile Support precompilation with Pike 8.1 again. o smartlink Fixed multiple issues on Darwin & NetBSD. o Whitefish Use the standard VPATH. o Yp Support using libtirpc. Glibc 2.26 has removed the Sun RPC implementation... Regards, -- Peter Bortas

8.0 and precompiled pike files...
by Stephen R. van den Berg 08 Mar '18

08 Mar '18

The current git version of 8.0, but it has been this way for at least the past two months, works fine for me as long as I remove all *.o files from the installed version. If I do not do that, it crashes right away with a segmentation fault. It does not matter if I compile it with gcc 6, 7 or 8. Same result. Is that just on my system, or is this a generic .o file dumping problem in pike 8.0? I regularly compile with: --with-cdebug --without-rtldebug --without-valgrind --with-double-precision --with-long-int --disable-noopty-retry --with-machine-code --without-portable-bytecode -g -O2 on an amd64 linux system (devel2, to be exact, from pikefarm). -- Stephen.

cp is different from rm/mv
by Stephen R. van den Berg 13 Feb '18

13 Feb '18

The reason why rm and mv are are first class citizens is because they correspond to libc/system calls (unlink and rename). "cp" has no libc/system call equivalent. commit 76dc18c99a3b30f91d5f3a7007b972081af9bc09 Author: Martin Nilsson <nilsson(a)fastmail.com> Date: Fri Feb 9 19:24:29 2018 +0100 Put cp() in the global scope, as rm() and mv() are already there. So polluting the global namespace with cp is not necessarily a logical step. -- Stephen.

Doc fixes and @namespace removal

Could someone please take a look at: commit a05ef1359a8c06e6f63ccd5ac8086d2c21823a2e (HEAD -> 8.1, origin/8.1, devel/8.1) Author: Stephen R. van den Berg <srb(a)cuci.nl> Date: Thu Feb 8 13:44:04 2018 +0100 Fix typos and docs. lib/master.pike.in | 24 +----------------------- lib/modules/Crypto.pmod/RC4.pmod | 2 +- lib/modules/Crypto.pmod/module.pmod | 2 +- lib/modules/Tools.pmod/Hilfe.pmod | 10 +++++----- src/sprintf.c | 2 +- src/string_builder.cmod | 3 +++ 6 files changed, 12 insertions(+), 31 deletions(-) I kicked out some @namespace and @endnamespace directives that autodoc complained about. I'm unsure if simply removing them had the desired effect. -- Stephen.
