Pike 8.0.528 release candidate
by Peter Bortas 11 May '18

11 May '18

As is tradition a release has been prepared at the new years party with Champagne in one hand and keyboard in the other waiting for the clock to hit 24:00. Pike 8.0.528 release candidate: https://pike.lysator.liu.se/pub/pike/beta/8.0.528/Pike-v8.0.528.tar.gz Other builds: https://pike.lysator.liu.se/pub/pike/beta/8.0.528/Pike-v8.0.528-Darwin-15.4… https://pike.lysator.liu.se/pub/pike/beta/8.0.528/Pike-v8.0.528-win32-oldli… Real Mac build comes when Bill has time to have a look at that. Changes since Pike 8.0.498 (release 11) ---------------------------------------------------------------------- New Features ------------ o Sql.pgsql - Added support for PostgreSQL 10's stronger password authentication (SCRAM-SHA-256). - Slightly reduced overhead. - Support IEEE binary float database-wireformat. - Prevent new queries from starting in the local_backend. o Crypto.Hash.SCRAM New class to support SCRAM authentication. o Thread.ResourceCount New module to allow threadsafe race-condition-free counting of resources. o SSL.File Support query_fd() and set_buffer_mode() methods. o Toole.Standalone.check_http - Allow redirect responses. - Support --expect option. Bug fixes --------- o Compiler Improved variant robustness. o Calendar Updated tzdata to 2017c. o Crypto.CCM Fixed initialization of the iv. o Filesystem.Monitor - Fixed issue with next_poll being set to zero causing polling every second. - Fixed indexing the NULL value error when InotifyMonitor was used in combination with a filter_file() that doesn't accept everything. o HTTPLoop: Fixed some potential race conditions. o Image.Image - Improved argument checking in apply_curve(). Non-integer array values lead to use of uninitialized curve values. o Image.PVR Fixed size check for twiddled images. o MIME Support trailing newline in MIME part epilogues. o Protocols.HTTP Fixed incoming chunked transfers (timed async works now, chunk options are properly 'parsed'). o Protocols.LDAP Fixed race condition on initializing LDAPS. o Search.Utils Updated debug string format. o Sql.pgsql - Suppress spurious 'File not open' blurts on stderr when the connection is still pending and we inspect the connection object. - Signal EOF early before closing the SQL result portal and thoroughly cleanup bufcon/stashcount to prevent occasional deadlocks on asynchronous object destructions. - Suppress rare "access in destructed object" messages. - Rip out fundamentally flawed reconnect logic, made failures consistent. - Repair SSL connect logic. - Update documentation. - Repair fetch_row_array(). o mktime/System.TM Make timezone management consistent (especially UTC handling). o Standards.IIM Disabled debug output for unknown segment markers. o Stdio.send_file Improved support for TLS/SSL; wait for TLS handshake to complete before calling the sendfile done callback when sending an empty string. This fixes the issue where the connection got closed before TLS handshaking was completed, confusing the other side. o Image Creating images with mode "grey" now works as documented, e.g. Image.Image(10,10,"grey",123); Optimizations ------------- o mktime/System.TM Considerable speedup and a reduction in codesize. Building & Tools ---------------- o Image.SVG Fall back to using the unprefixed pkg-config if the arch-prefixed doesn't exist. o Mysql Support MariaDB 10.2 headerfiles. o precompile Support precompilation with Pike 8.1 again. o smartlink Fixed multiple issues on Darwin & NetBSD. o Whitefish Use the standard VPATH. o Yp Support using libtirpc. Glibc 2.26 has removed the Sun RPC implementation... Regards, -- Peter Bortas

8.0 and precompiled pike files...
by Stephen R. van den Berg 07 Mar '18

07 Mar '18

The current git version of 8.0, but it has been this way for at least the past two months, works fine for me as long as I remove all *.o files from the installed version. If I do not do that, it crashes right away with a segmentation fault. It does not matter if I compile it with gcc 6, 7 or 8. Same result. Is that just on my system, or is this a generic .o file dumping problem in pike 8.0? I regularly compile with: --with-cdebug --without-rtldebug --without-valgrind --with-double-precision --with-long-int --disable-noopty-retry --with-machine-code --without-portable-bytecode -g -O2 on an amd64 linux system (devel2, to be exact, from pikefarm). -- Stephen.

cp is different from rm/mv
by Stephen R. van den Berg 12 Feb '18

12 Feb '18

The reason why rm and mv are are first class citizens is because they correspond to libc/system calls (unlink and rename). "cp" has no libc/system call equivalent. commit 76dc18c99a3b30f91d5f3a7007b972081af9bc09 Author: Martin Nilsson <nilsson(a)fastmail.com> Date: Fri Feb 9 19:24:29 2018 +0100 Put cp() in the global scope, as rm() and mv() are already there. So polluting the global namespace with cp is not necessarily a logical step. -- Stephen.

Doc fixes and @namespace removal
by Stephen R. van den Berg 08 Feb '18

08 Feb '18

Could someone please take a look at: commit a05ef1359a8c06e6f63ccd5ac8086d2c21823a2e (HEAD -> 8.1, origin/8.1, devel/8.1) Author: Stephen R. van den Berg <srb(a)cuci.nl> Date: Thu Feb 8 13:44:04 2018 +0100 Fix typos and docs. lib/master.pike.in | 24 +----------------------- lib/modules/Crypto.pmod/RC4.pmod | 2 +- lib/modules/Crypto.pmod/module.pmod | 2 +- lib/modules/Tools.pmod/Hilfe.pmod | 10 +++++----- src/sprintf.c | 2 +- src/string_builder.cmod | 3 +++ 6 files changed, 12 insertions(+), 31 deletions(-) I kicked out some @namespace and @endnamespace directives that autodoc complained about. I'm unsure if simply removing them had the desired effect. -- Stephen.

Protocols.DNS.server anyone used it in a DNS server?
by Stephen R. van den Berg 08 Feb '18

Has anyone ever used Protocols.DNS.server in an application (to implement a mini-DNS server)? Is the code available? -- Stephen.

Do you have any > before and after comparisons for this Tomasz? From cursory testing of Opera Mini transcoder where both Pike and Presto web browser engine using jemalloc on several machines for a few days I can see 15% - 20% smaller memory footprint at the cost of bigger CPU usage. But there's a lot of moving parts so these numbers should not be trusted. I'll have sound numbers in a week. -- Best Regards Tomasz Jamroszczak

MPI breaks on SunOS
by Stephen R. van den Berg 06 Feb '18

06 Feb '18

In case nobody noticed, Pikefarm seems to break on SunOS because it tries to compile in MPI without proper libs. -- Stephen.

Pull request - jemalloc
by Tomasz Jamroszczak 06 Feb '18

06 Feb '18

Hi. I'm first time poster. I'm working for Opera Software and I'm developing Opera Mini server, which involves quite a lot of Pike. I've added handling of jemalloc to Pike build and I'd like to upstream it to Pike repository. What's the procedure (a "pull request") to proceed with the change? -- Best Regards Tomasz Jamroszczak
