--[ Issue 12 ]- G A Z E T T E
brought to you by the Chicken Team
== 0. Introduction
Welcome to issue 12 of the Chicken Gazette, live from icebound rural
England!
== 1. The Hatching Farm
* Moritz Heidkamp added link shortcuts to hyde
* Peter Bex released a fix to charset encoding rules for fragment in
uri-common.
* Christian Kellermann merged in upstream changes to linenoise, and
provided
an input port usable in csi.
* Kon Lovett added posix-utils, which currently provides some
environment
access routines, but he hopes to add more miscellaneous POSIX
routines in
due course.
* Kon Lovett also moved the variable tools from moremacros into its
own
extension, variable-item.
* Kon Lovett, clearly on a roll by now, continued the programme of
improvements to srfi-29 with "package per thread" support.
* Felix Winkelmann released v0.8 of the bind egg, but neglected to
put
anything in the changelog so the consequences are a mystery to us
all!
* David Krentzlin released log5scm, a logging library based on CL's
log5
library
* Jim Ursetto updated sql-de-lite to SQLite v0.5.2 and fixed
`fold-rows*`
* David Krentzlin released his eagerly awaited nomads SQL database
migration
tool
* Moritz Heidkamp updated scss and then updated hyde to use it (along
with
another minor improvement)
== 2. Core development
Other than the usual fixing of minor bugs, it has been decided that the
ability
to statically build eggs is not worth maintaining; the first step, removing
documentation for this facility, has now been done.
But the big news is that version 4.6.3 has been tagged. Here's the
changelog:
- Peter Bex has cleaned up the makefiles heavily, making the
build more maintainable and easier to modify; thanks to all
who helped testing this new build
- renamed the makefile to `GNUmakefile' to catch using the
a make(3) other than GNU make
- `-fwrapv' is disabled on OpenBSD, since the default compiler
does not support this option (thanks to Christian Kellermann)
- on Solaris `gcc' is used by default, override `C_COMPILER'
to use the Sun compiler instead
- added the new foreign type `size_t' (suggested by Moritz
Heidkamp)
- added the missing `unsigned-integer64' foreign type (thanks
to Moritz for catching this)
- added support for proxy-authentification to `chicken-install'
(thanks to Iruata Souza)
- `define-record' now allows defining SRFI-17 setter procedures
for accessing slots
- removed the stub definition for `define-macro'
- added new foreign type `pointer-vector' which maps to `void **'
and provided a low-level API in the `lolevel' library unit
for manipulating pointer vectors
- declaring a function `notinline' will prevent direct-call
optimization for known procedure calls
- when compiling in C++ mode, the compiler will be called with
the `-Wno-write-strings' option
- the expansion of DSSSL lambda-lists uses now `let-optionals*'
internally instead of `let-optionals' and so allows back-references
to earlier formal variables; this also results in faster and
more compact code for argument-list destructuring (thanks to Alan
Post)
- Peter Bex has contributed various bugfixes and performance
enhancements to the `irregex' library unit
- fixed bug in `getter-with-setter' that modified the first argument
if it already had a setter procedure attached
- added a SRFI-17 setter to `list-ref'
- control-characters in symbol-names are now properly escaped if
the symbol is printed readably (thanks to Alaric Snell-Pym Blagrave
for pointing this out)
- added literal blob syntax ("#{ ... }")
- `delete-directory' now optionally deletes directories recursively
- fixed incorrect size of internal data vector used in `time'
(thanks to Kon Lovett)
- `list-tail' gives now a better error message when passed a non-list
argument
- deadlock in the scheduler now terminates the process instead of
attempting to throw an error
- added some sanity checks to the scheduler
- when installing from a local directory `chicken-install' now removes
existing `*.so' files in that location to avoid stale binaries when
the `make' syntax is used in setup scripts

Since 4.6.3 was tagged off, work has continued on the experimental and main
branches, in preparation for 4.6.4; further work on automatic
