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)?

GC fatal
by Stephen R. van den Berg 23 Apr '10

23 Apr '10

The following error has been occurring in all 7.8 Pike versions for the past 9 months (at least). I have a production machine running Roxen which crashes on an error like this roughly once a day. I'm willing to make custom changes to the production environment in Roxen and/or Pike to track this one down. Things that slow down the production environment for more than a factor of three are not acceptable. Any suggestions on how to tackle this problem? /data/src/gpike/src/gc.c:2519: GC fatal: Marked a thing without refs. **Block: 0xab493890 Type: object Refs: 0 **Got gc marker at 0xbcacbb0: flags=0x00000 refs=0 weak=0 xrefs=0 saved=-1 frame=(nil) **Program id: 66369 **The object is not on the object link list. **The object is destructed but program found from id. ******************* **Looking for references to 0xab493890: **Done looking for references to 0xab493890, found 0 refs.

I just tried converting Roxen 2.4: Stage Memory use Commits --------------------------------------- Import 339 MB ~17000 Raking 359 MB ~17000 Verify 361 MB ~17000 Merging 662 MB 11886 Graphing 803 MB 10897 Generate 803 MB 10897 I believe that the memory use can be reduced by using more custom datatypes (currently there are a lot of mappings generated in the merging and graphing stages). Another way to reduce the memory use is to partition the graphs in the time axis.

In svn, a change in a keyword value does not count as a change; the file does not indicate as modified and the result of "svn diff" is empty.

port.c does not work in CONFIGURE_TEST mode?
by Stephen R. van den Berg 01 Mar '10

01 Mar '10

On eureka-git.lysator.liu.se: --------------------- $ make configure [...] checking if union initialization works... yes checking if port.c works in CONFIGURE_TEST mode... no configure: error: port.c does not work in CONFIGURE_TEST mode. This is an internal problem in Pike. configure aborted since further configure tests will be unreliable. gmake: *** [configure] Error 1 --------------------- Is this a known issue? Any suggestions? -- Sincerely, Stephen R. van den Berg. I'm NaN.

The OS X manpage for ld mentions a "-macosx_version_min" option, are we correctly applying that one? I'm assuming it needs to match the number used for __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ for things to work out as intended.
