pike with -fstack-protector
by william＠welliver.org 12 Jun '20

12 Jun '20

I'm working on getting pike included in pkgsrc, and there's been a question about whether it's possible to get a usable pike with stack smashing protection enabled. When I originally prepared the port, I had to disable SSP on the build. In the intervening years I've forgotten the exact circumstances around why that's necessary. A suggestion was made that this problem has been overcome by newer versions of gcc for certain cases where it had been a problem, but I wanted to get more feedback to see if anyone is/has built and used pike with one of the various -fstack-protector options. Thanks in advance! Bill

expired pike.lysator.liu.se SSL certificate
by Stanislaw Klekot 12 Jun '20

A colleague of mine noticed that the SSL certificate of Pike's home page has expired a week ago. https://pike.lysator.liu.se/ We'd appreciate it getting renewed. -- Stanislaw Klekot

Any interest in an open source HTTP daemon in Pike? (Spike)
by Stephen R. van den Berg 12 Jun '20

12 Jun '20

I've written (for internal use) an HTTP daemon in Pike, using roughly the following featureset: - Mainly meant to run (custom) pike modules processing requests. - Also serves static content (through a simple config file). - Supports multiple virtual servers, with multiple mountpoints each. - Supports database connection pools. - Supports integrated memory caching. - Uses the Shuffler for all network I/O. - Supports websockets. - Gzips output automatically. - Uses statically precompiled .gz files if available and new enough. - It has been fondly baptised as a "Spike" daemon. - It integrates well with an nginx reverse proxy (and thus I did not add SSL support so far), which then adds HTTP/2 and SSL support. - It only runs on Pike 8.1, not Pike 8.0 (mostly because of the broken Shuffler in 8.0). - The whole source is about 15 KB (5 KB when gzipped). If there is interest, I'll clean up the code a bit more, and make it available via a git repo somehwere. -- Stephen.

Addressing the outer class
by Stephen R. van den Berg 11 Jun '20

11 Jun '20

class a { int c = 4; class b { int c = 3; void set(int d) { c = d; // FIXME } } void runme() { object y = b(); y->set(12); } } object x = a(); x->runme(); write("a->c %d\n", x->c); If I want this to print 12 (instead of 4), how do I need to tell Pike to access the c-member from b->set() in class a instead of the one in class b? -- Stephen.

Compiling programs in Pike master with proper error messages
by Stephen R. van den Berg 07 Jun '20

07 Jun '20

I'm using the following function in my spike-webserver: object compileit(string file, void|int quiet) { object prog; if (!quiet) log("Compiling %s", file); if (mixed err = catch(prog = compile_file(file)())) log(LOG_ERR, "Compile error %s", describe_backtrace(err)); return prog; } in order to compile modules. I'd like two things though, which currently don't quite work as I had hoped: a. When there is a compilation problem, I get a backtrace here, but it does not reveal what compilation error occurred (it does not show line number and diagnostics). Any suggestions how to get those? b. I'd like a (list of) custom library directories which I want to include in the namespace, without having to specify them on the commandline using -L options. How can this be accomplished? -- Stephen.

Protocols.HTTP.params_encode() and _decode()
by Stephen R. van den Berg 30 May '20

30 May '20

After having needed to program (HTTP) parameter decoding/encoding for the nth time, I decided to add some proper code for generic use. Any objections to the interface and/or naming? Is the solution fast enough? -- Stephen.

Annotation question
by H William Welliver 28 May '20

28 May '20

Given: A.pmod/B.pike inherit Pike.Annotation; A.pmod/C.pike inherit Pike.Annotation; and test.pike: @A.B; @A.C: string foo; function bar; class gazonk { @A.B; } I can do: > object o = ((program)"test.pike")(); > mkmapping(indices(o), annotations(o)); (1) Result: ([ /* 3 elements */ "bar": 0, "foo": (< /* 1 element */ A.C >), "gazonk": 0 ]) But I’m puzzled as to why gazonk is 0 and not (<A.B>). Also, how would I query program(“test.pike”) to see that it has A.C defined within it? I have not dug too far into this yet, just hoping there’s an obvious answer I’ve missed. Thanks in advance!

GL build error on MacOS 10.14
by H William Welliver 28 May '20

28 May '20

[I’m not very familiar with this module, so I’ll leave this as a bug report rather than fixing it myself] On MacOS 10.14, master fails to build the GL module with the following error: /Users/hww3/devel/pike/src/post_modules/GL/GLSL.cmod:800:5: error: use of undeclared identifier 'GL_LUMINANCE8_EXT Thats in glext.h but is guarded by GL_EXT_texture, so defining that before the include seems to make the error go away. Also, GL is deprecated as of 10.14, so in order to cut down on noise, I added -DGL_SILENCE_DEPRECATION to my build. Not sure if that’s desirable in general. Also, I noticed a bunch of grumbling in the Kerberos and GSSAPI modules about deprecations. Think that’s harmless noise (for now). Bill

Protocols.HTTP.Server.Request and a reference back to the listening socket?
by Stephen R. van den Berg 28 May '20

28 May '20

Once you have an accepted connection in Protocols.HTTP.Server.Request, is there a reference to the original listening socket the connection was accepted on? Why don't we preset the set_id()/query_id() value on the accepted socket with the one from the listening socket? -- Stephen.
