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

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

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.
