Process.run
by Peter Bortas (nu med mindre Opera) ＠ Pike (-) developers forum 15 Jul '08

15 Jul '08

I just checked in a Process.run() in 7.7: http://pike.ida.liu.se/development/cvs/diff.xml?module=Pike&file=7.7/lib/mo… The rational for that is that I was once again reminded by a user this week that getting Process.create_process() or Process.Process right without some corner case blocking is hard. It's not obvious that if you bind pipes to booth stderr and stdout you have to take in to account that OS buffers are not limetless. Process.run() is a thin wrapper around Process.Process … [View More]

It is time for a new release of Pike 7.6. Is there anyone who can do the release notes? If not, we'll just wait a bit longer...

sprintf %O
by Martin Nilsson (Opera) ＠ Pike (-) developers forum 20 Mar '06

20 Mar '06

While the new multiline sprintf %O looks snazzy, it will break code for everyone that uses it to ensure that a string contains no "bad" characters. Think log files, one line per entry. This needs to be reverted IMO as the effects on applications are hard to determine. For reference: Pike v7.7 release 23 running Hilfe v3.5 (Incremental Pike Frontend) > "foo\nbar"; (1) Result: "foo\n" "bar"

language.h in 7.7
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 01 Mar '06

01 Mar '06

Where is language.h supposed to be generated and why isn't it anymore? make in fresh checkout on an ubuntu machine stops at main.c as lex.h can't include language.h.

cyclic.c
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 28 Feb '06

28 Feb '06

In cyclic.c, shouldn't the thread be used to actually identify the cycle, not only as a component in the hash? Otherwise there is no use in setting th (or having) in the CYCLIC struct.

glibc-2.3.5 and threads/Process
by Hedda (www.linkmeet.com is now international) ＠ Pike (-) developers forum 21 Feb '06

21 Feb '06

(Everything is using Pike 7.6.66, but .64 has the same problem) I have a problem to get threads or Process to work properly with glibc-2.3.5 (or something related). I'm using Mandriva 2006 and Gcc-4.0.1. gcc-2.96 works just as badly. All my glibc-2.3.4 system works. /* Here is the program that hangs (after 2-6 "Ho!" and the same number of "Bar" usually, but sometimes it works) */ int xx=0; void main () { mixed a() { return allocate(10, thread_create) ( lambda() { … [View More]write("Ho!\n"); for (int x=0; x<10; x++) { for (int e=0; e<50; e++) if (Process.create_process(({"/bin/cat","/dev/null"}))->wait()) return e; } write("Hej!\n"); __signal_watchdog(); return -1; } )->wait() - ({-1}); }; mixed b() { return ({}); }; a(); write("Bar\n"); b(); write(( file_stat("/bin/cat") && file_stat("/dev/null") && all_constants()->thread_create && (cpp("__NT__")/"\n")[1]=="__NT__" ) +"\n"); write("xx"+xx+"\n"); } void __signal_watchdog() { xx++; return; } /* end program */ I have tried to build Pikes on the working systems and do "make bin_export" (Even with --without-dynamic-modules), but the result is the same. But if I try the Pike built by Roxen ( http://download.roxen.com/4.0/ in the Roxen Webserver 4.0.425 Fedora Core 4 x86 package) it runs the program above without problems, but it still hangs my Roxen about 2 times a day (when it's under heavy load). "hangs" means that it uses 0 CPU and doesn't do a thing, and needs to be killed with -9. So my question is: Has anyone else got glibc-2.3.5 to work perfectly with Pike (make verify)? And then: Is this Pike's or glibc's fault? If it's glibc's fault, then I need some help to write a bug-report. I did get some related warnings while compiling Pike: /home/hedda/Pike-v7.6.66/src/dynamic_load.c: In function 'exit_dynamic_load': /home/hedda/Pike-v7.6.66/src/dynamic_load.c:647: warning: variable 'tmp' might be clobbered by 'longjmp' or 'vfork' /home/hedda/Pike-v7.6.66/src/object.c: In function 'call_destroy': /home/hedda/Pike-v7.6.66/src/object.c:677: warning: variable 'e' might be clobbered by 'longjmp' or 'vfork' /home/hedda/Pike-v7.6.66/src/program.c: In function 'store_constant': /home/hedda/Pike-v7.6.66/src/program.c:5299: warning: variable 'e' might be clobbered by 'longjmp' or 'vfork' But when I fix the warnings by using "volatile"-declarations of these variables, the above program still doesn't work, so I guess it's unrelated. Grubba had the theory: >"~ Your header-files probably don't match your thread-libraries. ~" >(14133489) /Henrik Grubbström (Lysator)/-- But that doesn't seem to be the case, as this is happening on two different systems, and they _should_ be OK. But there might of course be a Mandriva 2006-problem with its headerfiles or something. [View Less]

PCRE benchmark problem?
by Adam Montague 18 Feb '06

18 Feb '06

Running "pike -x benchmark" using a fairly recent pike 7.7, I get really bad results on the "Tag removal u. Regexp.PCRE" test. So bad that I've actually never bothered to let it finish, it just sits there sucking up CPU for a long time. If I change the number of times the test is run from 2000 to 200 I can see that it actually does work, its just incredibly slow. Is this normal, or is my PCRE lib performing horribly badly for some reason? Here's what it looks like after changing n to be 200 … [View More]

patch to support schemas in Sql.postgres()->list_fields
by Adam Montague 15 Feb '06

15 Feb '06

This patch lets you do db->list_fields("schema.table") on Sql.postgres objects, which is needed if you have tables with the same names in different schemas. It also fixes the check for has_relexpires which wasn't using a valid SQL query. Adam
