[-1210947904]BACKEND[0]: fd 40 has revents 0x00000008, but hasn't been handled.
by Stephen R. van den Berg 27 Apr '10

Anyone who has seen this before?: [-1210947904]BACKEND[0]: fd 40 has revents 0x00000008, but hasn't been handled. It happens rather sporadically in a Roxen production server (the same one we just upgraded to bleeding edge Pike); in fact, it's the first time I see it. The server appears to hang at that point, so my watchdog script (external) kills the server and restarts it after that. -- Stephen.

GC fatal
by Stephen R. van den Berg 22 Apr '10

22 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.

Pike7.6 and inetd Outputs null byte on Debian Lenny (5.0)
by redax＠redax.hu 13 Apr '10

13 Apr '10

Hi, I'm just upgraded a system from a prior debian to the recent one (from etch /4.0 to lenny/5.0 ) and I had a script which is run by inetd. it was worked so far, but now it outputs a null byte (\0) to the stdout even if the script does not writes to the stdout. if I run the _SAME_ script on an older system, it works no null byte, from Shell, it works, again no leading null byte. just from inetd. I also tried to change bsd inetd to rlinetd, same effect. do you have any idea what makes that extra null byte? Thanks, Redax

Problem with "Cannot access global variables in destructed object"
by Coen Schalkwijk 29 Mar '10

29 Mar '10

Hello Everybody, Did I ask a stupid question when I said I have problems with accessing global class variables in a function during program shutdown? If I did, I'd also like to know, no offense taken :) -- Met vriendelijke groet / With kind regards / mit besten Grüßen, Coen Schalkwijk Software Engineer coen.schalkwijk(a)rtl.nl <mailto:coen.schalkwijk@rtl.nl> coen(a)rtlinteractief.nl <mailto:coen@rtlinteractief.nl> +31 (0)35 671 8915

CVS repository conversion
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 27 Mar '10

27 Mar '10

I'm currently in the progress of comparing grubba's git conversion of the Pike repository to my svn conversion, which should improve the quality of both. I've encountered a systematic difference where some kind of policy decision on what is "right" is needed though. The issue is with tags. In CVS, each file is tagged separately. If a file does not have a particular tag, you will not get that file when you check out the tag. There are in fact quite a few files in Pike which do not have certain tags even though they were current on trunk when the tag was made. This is typically the case with modules which were initially developed outside the main tree (and imported using the CVS "module" concept, which is not understood by cvs rtag). Examples include: lib/modules/SSL.pmod/ src/post_modules/COM/ src/post_modules/SDL/ src/post_modules/Shuffler/ src/post_modules/_Image_SVG/ lib/modules/Audio.pmod lib/modules/Tools.pmod/Legal.pmod Then, there is also a few tags (so far I have encountered v7_1_7, v7_1_20, and v7_7_28) where large parts of the tree (including src/ in its entirery) do not have the tag, suggesting that the tagging operation was interrupted, and the resulting broken tag was just left there instead of being (re)moved. So, there are two principle approaches here: Should the tags in the converted repository accurately reflect the tags in the CVS repository, so that you only get those files you would have gotten out of CVS, or do we take the revisionist approach of including also such files which do not have the tag but which were present on head when the tag was created, and therefore "ought" to have been tagged?

[Pike/Roxen] Problems with destructing objects during Roxen shutdown...
by Coen Schalkwijk 15 Mar '10

15 Mar '10

Hi All, [Something went wrong in sending this msg, might be you get this msg twice, sorry for that] I get a lot of 'Cannot access global variables in destructed object' errors when rebooting Roxen. It looks as though a function call is completed even after the object is destructed. I only get the error when setting (private) class members of an object. The rest of the functions seems to execute without problem. Is there any way to prevent this? Like either not execute the function if the object is (going to be) destructed or not destruct an instance until the function has completed? Thanks in advance! Coen RTL Nederland

Yes thats true. The whole thing is kindof pointless in the big picture. However, in browser applications we are pretty much stuck with javascript which cannot live without it. And using chunked-encoding one actually gets something like a TCP connection (at least one way from server to client).

chunked-encoding
by Arne Gödeke 14 Mar '10

14 Mar '10

In the yakitychat code we are currently abusing the Protocols.HTTP.Server.Request objects to do comet-like streaming using chunked-encoding. Right now we are just taking over the Stdio.File object but it would be nicer if the Request api had something like a send() function to send chunked encoded data. I was thinking about merging those portions of the into the Protocols.HTTP.Server.Request code. Is there anyone who already did this or has there been a discussion about the api? arne
