Re: Playing music using pike and SDL.
by Martin Nilsson (lvl 60) ＠ Pike (-) developers forum 13 Mar '26

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)?

managing comport settings in linux
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 13 Mar '26

13 Mar '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.

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

Final feedback for 7.8.686
by H. William Welliver III 29 Jun '12

29 Jun '12

It's been about 2 weeks since I cut a new 7.8 release candidate and I haven't heard much feedback, good or bad. Since there weren't many problems with the previous release, I'm going to assume that everything is okay. However, if anyone has any feedback, please let me know, as I plan to mark it as an "official release" build. Assuming all goes well, what are the changes that a Windows build and friends can be ready in the near future? I tried doing a build, but I think things have moved on (at the time, using VC6 worked, etc) since my last Windows build adventure. Best, Bill

ZIP file program loader
by Bill Welliver 21 Jun '12

21 Jun '12

When I was in Sweden last fall, I remember having a brief conversation with someone who'd written a resolver that loads classes or modules from a tar or zip file (the details are a little hazy). Does that sound familiar to anyone here? If so, do you have any code you might be willing to share? Bill

USB.devices OneWire.devices, how to unite it into an IO module?
by Stephen R. van den Berg 14 Jun '12

14 Jun '12

I currently have a functioning usblib module, and for now it lives in src/post_modules/USB in my personal tree. I am now embarking onto creating a OneWire module/class which uses the aforementioned USB lib to actually communicate with the 1-wire busmaster. The question is, where do I put all these modules. Most logical would be under a module named IO, so it would become IO.USB.devices and IO.OneWire.devices or somesuch. Then again, the USB module is completely written as a cmod. The OneWire module might live as a Pike module. How do I solve the namespace problem, I'd like to unite them under master module IO? Renaming the USB module to _USB, then inheriting the module under lib/modules/IO.pmod again might work, but gets messy with autodoc, since I'd like to keep the documentation in the cmod file itself. Any suggestions? -- Stephen. How many weeks are there in a lightyear?

Pike 7.8 Release (last call)
by H. William Welliver III 12 Jun '12

12 Jun '12

Does anyone have any objections to 7.8.680 becoming the next official release of Pike? Do note that machine code is non-functional on (at least more modern instances of) i386. If I don't hear any objections in 24 hours, I will attempt to update the website, etc, with the new information. Best, Bill
