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.

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.

pike-git.lysator.liu.se unreachable?
by Stephen R. van den Berg 25 Feb '10

25 Feb '10

Is there a good reason why pike-git.lysator.liu.se is unreachable? -- Sincerely, Stephen R. van den Berg. A: Because it messes up the order you normally read text in. Q: Why is top-reply so bad? A: Top-reply. Q: What is the most annoying thing in E-mail?

Re: Testsuite failures (Re: Gz.FIXED and Windows build)
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 21 Feb '10

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.

SO_REUSEADDR after an accept()?
by Stephen R. van den Berg 21 Feb '10

21 Feb '10

Why are we setting SO_REUSEADDR on a filedescriptor/socket that came from an accept()? (in socket.c) IMO that seems useless. For a socket used in a bind(), it makes sense, but not for anything else. Any insights? (Henrik? You touched that piece of code last). -- Sincerely, Stephen R. van den Berg. A sign seen in a jewelry store window: "Ears pierced while you wait"

Gz.FIXED and Windows build
by Stephen R. van den Berg 20 Feb '10

20 Feb '10

In checking the Windows build I notice: -------- Doing tests in modules/Image/testsuite (1480 tests, pid 44356) Cond 1477:1:Index 'FIXED' not present in module Gz. Cond 1477:1:Indexed module was: Gz. Conditional 1477 (line 827) failed. Doing tests in modules/Mysql/testsuite (0 tests, pid 45592) -------- The testsuite of Gz seems to be ok, though. Any takers? -- Sincerely, Stephen R. van den Berg.

New uLPC CVS repository added.
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 20 Feb '10

FYI: In my mission to reconstruct the early history of Pike, I've just created a new CVS repository "ulpc.lost-doc", which contains some documetation files that I've reconstructed from the surviving uLPC dists.
