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.

eureka reinstall
by Peter Bortas ＠ Pike developers forum 07 Jan '10

07 Jan '10

Some time next week I'll upgrade eureka from Solaris Express snv_81 to whatever the latest stable OpenSolaris release is. There is no straight forward upgrade path from SXCE to OpenSolaris, so the machine will be reinstalled and the data restored from backup. That means there will be some substancial downtime for people using services on eureka. More details later.

do_async_method_url ignoring content-type
by Arne Goedeke 14 Nov '09

14 Nov '09

do_async_method_url overrides the content-type given in extra headers. Its possible to work around it by using "Content-Type" instead of "content-type". This is relevant at least in the XMLRPC module, not sure if anybody noticed. here is a patch arne diff --git a/lib/modules/Protocols.pmod/HTTP.pmod/Session.pike b/lib/modules/Protocols.pmod/HTTP.pmod/Session.pike index 5b82fc9..b7e2e74 100644 --- a/lib/modules/Protocols.pmod/HTTP.pmod/Session.pike +++ b/lib/modules/Protocols.pmod/HTTP.pmod/Session.pike @@ -874,8 +874,8 @@ Request async_do_method_url(string method, if (method=="POST") extra_headers= - (extra_headers||([]))+ - (["content-type":"application/x-www-form-urlencoded"]); + (["content-type":"application/x-www-form-urlencoded"])+ + (extra_headers||([])); p->do_async(p->prepare_method(method,url,query_variables, extra_headers,data));

replace
by Mirar ＠ Pike developers forum 29 Oct '09

why do > replace(({1,2,3}),2,17); (6) Result: ({ /* 3 elements */ 1, 17, 3 }) work, while > replace(({1,2,3}),({2}),({17})); (5) Result: ({ /* 3 elements */ 1, 2, 3 }) does nothing?

release
by Peter Bortas ＠ Pike developers forum 22 Oct '09

22 Oct '09

It's time to do a stable release again. If you have low risk but potentially build breaking code in the pipe then check it in now. I'll aim for a release next week.

pcvs2git.pike

The above file is now available via git://pike-git.lysator.liu.se/pcvs2git.git/ Note: Requires rcs (and git). Note that the tool is by no means finished, but it seems to generate an acceptable git archive from the repositories that I've tested with. Caveat emptor: I've not tested with any repositories larger than the Pike 0.5 repository yet (~7000 file revisions).

evil optimization
by Arne Goedeke 14 Oct '09

14 Oct '09

In the following case the optimizer seems to assume, that the array does not change during the loop and optimizes away the sizeof check: int main() { array a = ({ 1, 2, 3, 4, 5 }); void magic(int k) { a = a[0..k-1] + a[k+1..]; }; for (int i = 0; i < sizeof(a); i++) { if (a[i] == 2) { magic(i); i--; } } return 0; } I assume cases like this are hard to detect, especially because this can me made even more complicated. I will put in some if (0) { ret = ({});} equivalent to trick the optimizer for now. arne

pike meet-up in copenhagen
by Bill Welliver 09 Oct '09

09 Oct '09

Just thought I'd post a reminder that a number of Pike devotees will be in Copenhagen for a few days this month (at least the 24th and 25th, I'll be there a day before and after, as well). We'll probably having all kinds of conversations, and it coincides with Open Source Days, so a few of us will be manning a "booth" and doing presentations. We always have some good conversations and cool things often sprout from them, and new faces (and old friends, of course) are always welcome. I'm told that Denmark is relatively close for folks in Scandanavia, so do consider coming down for a visit if you're in the region! For more details, drop myself or our man-on-the-ground, Matt Hardy (matt(a)webhaven.eu) a line. Best, Bill
