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 09 Apr '26

09 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)?

debugger opcodes
by Bill Welliver 30 Oct '14

30 Oct '14

I noticed that folks have been working on code generation lately. Any chance it might be possible to implement some of the opcodes required to get debugging working (step, break, etc)? I seem to recall someone indicating it wasn't a terribly difficult task, but it's clearly beyond my understanding of the problem. Bill

Sql.pgsql behavior in case of errors
by aldem-pikedev＠aldem.net 21 Aug '14

21 Aug '14

Hi everyone, I am preparing to use Postgres in my app, found the following strange behavior: ---snip--- Sql.Sql db = Sql.Sql("pgsql://localhost", "test", "test", "test"); db->query("BEGIN"); db->query("INSERT INTO requests (SvTrId) VALUES ('lala')"); catch(db->query("INSERT INTO requests (SvTrId) VALUES ('lala')")); db->query("INSERT INTO requests (SvTrId) VALUES ('juju')"); db->query("ROLLBACK"); ---snip--- Database is opened, row with 'lala' is inserted, second query (obviously) fails as SvTrId is the primary key, but row with 'juju' is inserted *and* appears in the database - i.e. the transaction is *committed*! Studying source code show, that once error is encounter, session is reset, i.e. running transaction is rolled back, everything is closed, temporary tables are deleted and session variables are reset as well, and after that, the next statement(s) will be committed immediately, as there is no active transaction. In my opinion, this is not exactly correct behavior when statement fails, as session still may be needed (especially temporary tables, open cursors etc). Im some cases, this is perfectly normal when SQL statement fails, especially in SERIALIZED transaction isolation level, and it would be more practical to leave the decision as of what to do to the application. Yes, this is true that it is impossible to continue executing statements in failed transaction, but temporary tables etc. may still be needed. Also, silent reconnection is not a good idea too - when there are many transactional statements are executed - it would be nice to have an option to modify this behavior. Best regards, /Alexander

Packagers?
by Bill Welliver 31 Jul '12

Do we have anyone handling Debian packages, or RPMs or the like? I know Grubba does an ebuild but was wondering if there are any others that need to be prepared for a new release? Bill

Well, I've uploaded a binary release for Solaris 11 64-bit (should run on OI too), with a working Gettext module. Both libintl and libiconv seems to be the GNU versions (from OpenCSW).

Pike 7.9
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 29 Jul '12

29 Jul '12

I was looking through the testsuite failures in 7.9. I think that these two are the only two regressions (and possibly the type system ones as well, but that could also be due to grubbas tweaking). int gnu (mixed... args) {}; gnu(@indices (all_constants()), gauge { foreach (({1,2,3}), int j) do if (j && gnu(@indices (all_constants()), 17 + gauge {break;})) return 0; while (0); }); #pragma strict_types void x (void|mapping(string:string) args) { if (args) foreach (indices (args), string a) werror ("%O\n", a); }
