sslfile
by Bill Welliver 13 Jan '04

13 Jan '04

I just tried using HTTP.Protocols.Server.SSLPort in a recent CVS 7.5, and ran into a bunch of problems. Seems there's been a good bit of work on SSL.sslfile recently. I spent about an hour trying to track the problem down, and think I need to defer to someone who's more familiar with the changed material. It looks like the set accept_callback isn't being called with the sslfile object anymore (which is what was happening before). This (obviously) causes problems with code that wants to use the connection that has been negotiated. I traced the problem back in sslfile, and it looks like the accept callback is getting called with the argument of callback_id, which doesn't appear to be set anywhere in the current code, hence it's just a zero. It also doesn't appear to be set anywhere within sslfile to anything other than zero or one. Can anyone with more experience take a look at this and offer suggestions? Bill

No, because gdb_backtraces() requires a running process. Anyway, I run the thread in gdb and caught it: | THREAD_ID 0x4000 (swapped in): | src/modules/Gmp/mpz_glue.c:2037: `/(0) | -:420: test() | /home/mirar/pike/longlongint/test-install/pike/7.5.15/lib/modules/Tools.pmod/Shoot.pmod/CompileExec.pike:56:perform() It seems like mpz can crash on division by zero? Or does mpz::`/ destroy the stack entry?

Dependency range
by Martin Nilsson (saturator) ＠ Pike (-) developers forum 12 Jan '04

12 Jan '04

What is the range of the OPT_EXTERNAL_DEPEND? The same process? The same computer? The real problem in the issue is dumping I suppose. As an example getpid is added as efun in two places in Pike, in one of them it is marked as OPT_EXTERNAL_DEPEND and in one it is not, underlining the confusion.

explode_path
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 12 Jan '04

12 Jan '04

I've been thinking a bit about explode_path(). Despite the fact that I don't like the function anyway, I think it could be made at least slightly useful if the semantics was changed so that combine_path(@explode_path(X)) == combine_path(X) (I think this is how things originally worked, but since then combine_path has been updated to behave more logically. :) For UNIX, the only change would be that explode_path("/foo/bar") would return ({ "/", "foo", "bar" }) instead of ({ "", "foo", "bar" }). For AmigaOS and possibly W*ndows, the impact would be a bit larger. The problem is of course that code which does f(explode_path(X))*"/" will break. OTOH, it doesn't seem like the docs say that this should work in the first place... Maybe the old behaviour should be retained by #pike 7.4...

#include
by Credence Shanden 12 Jan '04

12 Jan '04

Well this is my first attempt with PIKE, although I am familiar with the LPC language some things seem to be a bit different in PIKE. My problem is that I am trying to include a file but I get the error that the file could not be read. I am assuming that somehow I am typing the directory wrong. I have tried many different ways including typing out the full directory name. I have kernel.pike which is the main pike program running in the base directory and the include works there with #include "includes/kernel.h". I tried this with my login sequence file which is located at /lib/obj/std/login.pike but it says it can not find the file. And for future reference I am sure I will be sending out alot of questions. Thanks all in advance. --------------------------------- Do you Yahoo!? Yahoo! Hotjobs: Enter the "Signing Bonus" Sweepstakes

icc & nan
by Mirar ＠ Pike developers forum 12 Jan '04

12 Jan '04

My icc (7.1) bugs in comparison of NaN. But Pike has it's own support of NaN, doesn't it? Is there any simple way of turning on that support, so I can write a configure test to turn off using a native NaN if it doesn't work?

How did you track down lost fds, again? (Protocols.Bittorrents eat them all.)

C#-like properties
by Marcus Agehall (Scanian) ＠ Pike (-) developers forum 11 Jan '04

11 Jan '04

While working on my master thesis, I have once again discovered the many similarities between C# and Pike. With the C# spec 2.0, C# will become even more Pike-like and for example introduce lambda expressions. At present, there is one thing in C# which I would very much like to see in Pike. C# has a concept called property. It's a mix of a variable and methods to get and set that variable. It is considered good OO-practise to hide variables and use methods to access them but this causes a lot of polution within the namespace of a class with a log of variables if each one must have a getFoo() and a setFoo() method. Here is how to do it the C# way: private int foo; public int Foo { get { return foo; } set { foo = value; } } To access the Foo property, one just uses it just like a normal variable: int x = Foo; Foo = x+1; C# appears to implement this by turning the property into two methods, which in the example above would be called get_Foo() and set_Foo(). These methods cannot be called directly by the code, attempts to do so causes a compilation error. In my sample, there is not much use in having a property, since no processing of the value is done, but in real life situations, there are many times I found that I may want to limit the value set by the caller to a certain range or similar. This is easily done with properties in C#. Ofcourse, the problem can be solved by implementing the get and set methods manually, as one does today, but I believe that the C# way is much better looking and, at least to me, feels more natural. My suggestion is that we put implementation of a C#-like property concept on the TODO-list. Thoughts, other ideas?

sscanf()
by Credence Shanden 10 Jan '04

10 Jan '04

Hello it seems as if I am having a tiny little problem with sscanf(). I am trying to match the input given to a string via sscanf. It's a simple little deal but the format I am using obviously isn't working although it has in the past. Here is the code snippet: if(sscanf("quit", sCommand + "%*s")) Now what I am trying to accomplish is to see if the player typed anything pertaining to the word quit. I.E q, qu, qui or even quit itself....Yes why not do a simple if/else. Well because there will be other commands that can be executed that will be longer. Am I setting this up wrong? It has worked in the past outside of pike but still in LPC. I even tried search("quit", sCommand) and that seemed to only return -1 no matter what I typed. Thanks in advance all. --------------------------------- Do you Yahoo!? Yahoo! Hotjobs: Enter the "Signing Bonus" Sweepstakes

NettleNettle???
by Martin Bähr 09 Jan '04

while looking at the putty links i discovered: http://nettlessh.mine.nu/ with the interresting thing that nettle itself: http://nettle.sourceforge.net/ has nothing to do with crypto. one could presumably combine the nettle terminal with the nettle crypto lib and create: nettlenettle ;-))) greetings, martin.
