Hi. At Pike Conference 2017 it was decided that we ought to hold a more informal meeting in Linköping ~ once every quarter. As the three month mark from the conference is coming up soon, it seems time to announce the first such meeting for 2018: Pike Meet-up 2018-Q1 Date: 2018-02-03 (Sat) Time: 10:00 - afternoon/evening Place: Roxen IS AB S:t Larsgatan 22A Linköping Welcome! /grubba

Operator assignment and strict_types
by Marc Simpson 07 Jul '20

07 Jul '20

Hi folks, It looks like operator assignment (op=), increment and decrement statements aren't subjected to the same typechecks as their more explicit equivalents. For example, neither the post-increment nor += statements below warn with strict_types enabled, even though they assign values outside of foo's restricted int domain: int(3..3) foo = 3; foo++; // no warning foo += 1; // no warning foo = foo + 1; // warning from strict_types Similarly, operator assignment on aggregates fails to elicit a warning: array(int) a = ({}); multiset(int) b = (<>); mapping(int:int) c = ([]); // no warnings a += ({ "hey" }); b += (< "hey" >); c += ([ "hey": "there" ]); // warnings from strict_types a = a + ({ "hey" }); b = b + (< "hey" >); c = c + ([ "hey": "there" ]); I'm guessing this is because the checks provided by the F_ASSIGN/F_ASSIGN_SELF case (las.c) only apply to direct assignment; op= and friends are presumably not instrumented for strict_types in the same manner. Have there been any discussions around addressing this inconsistency? Thanks, Marc

Remixml, javascript module
by Stephen R. van den Berg 25 Feb '20

25 Feb '20

This might be of interest to the Pike and/or Roxen community: https://www.npmjs.com/package/remixml I just launched it. Using it in a Single-Page-Application website. Any critical feedback is welcome (I'm currently the only user, so changes in the API are easy and still allowed). >From the description: Remixml is an XML/HTML macro language/template engine. The language and primitives used blend in completely with standard XML/HTML syntax and therefore integrate smoothly with existing XML/HTML syntax colouring editors. Requirements It runs inside any webbrowser environment (starting at IE11 and up). For historical reference: Remixml was originally inspired by RXML, the Roxen webserver macro language. -- Stephen.

Pike 8.0.690 beta/release candidate
by Peter Bortas 12 Sep '18

12 Sep '18

Pike 8.0.690 beta/release candidate: https://pike.lysator.liu.se/pub/pike/beta/8.0.690/Pike-v8.0.690.tar.gz Other builds: https://pike.lysator.liu.se/pub/pike/beta/8.0.690/Pike-v8.0.690-Darwin-15.4… https://pike.lysator.liu.se/pub/pike/beta/8.0.690/Pike-v8.0.690-win32-oldli… Changes since Pike 8.0.610 (release 12) New Features ------------ o Sql.mysql In unicode decode mode, characters outside the BMP are now encoded as UTF-8 encoded UTF-16. This works around that MySQL/MariaDB don't allow characters outside the BMP in utf8 strings (and instead require the character set to be declared as utf8mb4, which has quite a few side effects). Bug fixes --------- o Runtime - Fixed loss of Pike_interpreter_pointer (race, --with-debug only). The Pike_interpreter_pointer must not be altered by threads not holding the interpreter lock... o Calendar - Updated tzdata to 2018e. o Compiler - The machine code generator for ppc64 now generates correct code under ABI v2 (ppc64le) - Fixed an incompatibility between the machine code generator on ppc and GCC 7. - Support inherit of CompilerEnvironment. Fix some bugs triggered in the supporter subsystem when executing in an inherited CompilerEnviroment. o Filesystem.Monitor - Fix NULL-dereference in bump(). Survive st being zero in bump(). o Fuse - Switched the Fuse module to use a different libfuse API. The way we used to use libfuse got first deprecated and support for it is now removed from the libfuse git repository entirely. In addition, our previous use of said libfuse API triggered a bug resulting in a segmentation fault in at least libfuse 2.9.2 and 2.9.7. We now use libfuse in a less elegant but more usual way, and do not trigger the bug anymore. - Handle errors in Fuse operations (i.e. Pike code implementing FUSE filesystems) gently by reporting ENOSYS instead of exiting the process. o Gmp.mpq Fix numbers between -1.0 and 1.0 sometimes missing a leading 0. o Pike.identify_cycle Fix various issues with LFUNs throwing errors. LFUNs used by mapping operations may throw errors; this caused identify_loop_visit_leave() to also throw errors. The rest of the identify_cycle code was not happy about this and - Forgot to unlock the mc_mutex. This caused all following calls to Pike.identify_cycle() and Pike.count_memory() to hang. - Leaked memory. The above issues are now avoided by instead using the addresses of objects as indices in the affected mapping. It also fixes the issue with hangs if there are objects with lfuns calling Pike.identify_cycle() or Pike.count_memory(). o Protocols.HTTP.Server Fix an issue with accounting of sent bytes that caused responses to requests over HTTPS to not finish on success, but instead the whole connection to time out. Data for the first request was usually fully written, but the connection neither was properly closed nor re-used. o Sass - Errors thrown by handle_sass_import() can now be caught and handled by the caller of compile_file() and compile_string(). - Added the option "sass_syntax". This option will parse the input as having indented Sass syntax. This option only has effect in compile_string(). - Added method sass2scss() to convert Sass syntax to SCSS syntax. o Sql.pgsql - Fix regression bug since rel 12 that hangs queries returning over 1024 records. - Fix all rare-deadlock-causes logged in the last two years. o Stdio.Buffer Eliminate race condition in read_cstring(). o Thread.Farm - Fixed lost error in provide_error() exception handling. - Avoid delayed deallocation of jobs by clearing references immediately after execution. o Tools.Standalone - extract_autodoc: Terminate on failure. Reenable termination on extraction failure. Building & Tools ---------------- o Java - The location of libjvm is now detected on Ubuntu 18.04. - Detect and support OpenJDK 10. o Postgres Support Postgresql 10 and later. Regards, -- Peter Bortas
