New features between zsh versions 4.0 and 4.2
Configuration:
* upgraded to use autoconf post-2.50
* improved compatibility with other shells through shell options, builtin
arguments and improved builtin option parsing
Syntax and builtins:
* new printf builtin
* `+=' to append to parameters which works for scalars, arrays and (with
pairs) associative arrays.
* enhanced multiple parameter `for' loops: for key value in key1 value1 key2
value2 ... maintaining full compatibility with POSIX syntax.
* Suffix aliases allow the shell to run a command on a file by suffix, e.g
`alias -s ps=gv' makes `foo.ps' execute `gv foo.ps'. Supplied function
zsh-mime-setup uses existing mailcap and mime.types files to set up suitable
aliases. Supplied function pick-web-browser is suitable for finding a browser
to show .html etc. files by suffix alias.
* new option `no_case_glob' for case-insensitive globbing.
Add-on modules and functions:
* zsh/datetime modules makes date formatting and seconds since EPOCH available
inside the shell.
* zsh/net/tcp module provides builtin interface to TCP through ztcp builtin.
Function suite for interactive and script use with expect-style pattern
matching.
* zsh/net/socket module provides zsocket builtin.
* zcalc calculator function with full line editing.
* builtin interface to pcre library
* zsh/zselect module provides zselect builtin as interface to select system call
Completion system:
* general improvements to command and context support, low-level functions,
display code.
* in verbose mode, matches with the same description are grouped
* highly configurable completions for values of specific parameters, specific
redirections for specific commands
* support for bash completion functions (typically zsh native functions are more
powerful where available)
* New completions provided for (some of these may be in later 4.0 releases):
valgrind, tidy, texinfo, infocmp, Java classes, larch, limit, locale
parameters, netcat, mysqldiff, mt, lsof, elinks, ant, debchange (dch), email
addresses, file system types, Perforce, xsltproc. Plus many others.
Line editor:
* special parameters $PREDISPLAY, $POSTDISPLAY available in function widgets
to configure uneditable text (for narrowing)
* recursive editing
* supplied widgets read-from-minibuffer, replace-string use these features
(more intuitive prompting and argument reading than 4.0)
* access to killed text via $CUTBUFFER and $killring
* supplied highly configurable word widgets forward-word-match etc., can set
what constitutes a word interactively or in startup script (implement
bash-style behaviour, replacing previous bash-* word widgets)
* interface to incremental search via $LASTSEARCH
* better handling of keymaps in zle and widgets
* better support for output from user-defined widgets while zle is active
* tetris game which runs entirely in zle
* several other contributed widgets
Local internal improvements:
* disowned jobs are automatically restarted
* \u and \U print escapes for Unicode
* read -d allows a custom line ending.
* read -t .
* line numbers in error messages and $PS4 output are more consistent
* `=prog' expands only paths, no longer aliases for consistency
* job display in prompts; `jobs' command output can be piped
* prompts: new $RPROMPT2, %^, %j, %y, enhanced %{, %}, %_.
* rand48() function in zsh/mathfunc for better randomness in arithmetic
(if the corresponding math library function is present)
* $SECONDS parameter can be made floating point via `typeset -F SECONDS'
for better timing accuracy
* improvements to command line history mechanism
* job table is dynamically sized, preventing overflow (typically seen
previously in complex completions).
* many bugfixes
Changes since version 8.12.10:
Use QueueFileMode when opening qf files. This error was a
regression in 8.12.10. Problem detected and diagnosed
Lech Szychowski of the Polish Power Grid Company.
Properly count the number of queue runners in a work group and
make sure the total limit of MaxQueueChildren is not
exceeded. Based on patch from Takayuki Yoshizawa of
Techfirm, Inc.
Take care of systems that can generate time values where the
seconds can exceed the usual range of 0 to 59.
Problem noted by Randy Diffenderfer of EDS.
Avoid regeneration of identical queue identifiers by processes
whose process id is the same as that of the initial
sendmail process that was used to start the daemon.
Problem noted by Randy Diffenderfer of EDS.
When a milter invokes smfi_delrcpt() compare the supplied
recipient address also against the printable addresses
of the current list to deal with rewritten addresses.
Based on patch from Sean Hanson of The Asylum.
BadRcptThrottle now also works for addresses which return the
error mailer, e.g., virtusertable entries with the
right hand side error:. Patch from Per Hedeland.
Fix printing of 8 bit characters as octals in log messages.
Based on patch by Andrey J. Melnikoff.
Undo change of algorithm for MIME 7-bit base64 encoding to 8-bit
text that has been introduced in 8.12.3. There are some
examples where the new code fails, but the old code works.
To get the 8.12.3-8.12.10 version, compile sendmail with
-DMIME7TO8_OLD=0. If you have an example of improper
7 to 8 bit conversion please send it to us.
Return normal error code for unknown SMTP commands instead of
the one specified by check_relay or a milter for a
connection. Problem noted by Andrzej Filip.
Some ident responses contain data after the terminating CRLF which
causes sendmail to log "POSSIBLE ATTACK...newline in string".
To avoid this everything after LF is ignored.
If the operating system supports O_EXLOCK and HASFLOCK is set
then a possible race condition for creating qf files
can be avoided. Note: the race condition does not
exist within sendmail, but between sendmail and an
external application that accesses qf files.
Log the proper options name for TLS related mising files for
the CACertPath, CACertFile, and DHParameters options.
Do not split an envelope if it will be discarded, otherwise df
files could be left behind. Problem found by Wolfgang
Breyha.
The use of the environment variables HOME and HOSTALIASES has been
deprecated and will be removed in version 8.13. This only
effects configuration which preserve those variable via the
'E' command in the cf file as sendmail clears out its entire
environment.
Portability:
Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther).
Solaris 10 has unsetenv(), patch from Craig Mohrman of
Sun Microsystems.
LIBMILTER: Add extra checks in case a broken MTA sends bogus data
to libmilter. Based on code review by Rob Grzywinski.
SMRSH: Properly assemble commands that contain '&&' or '||'.
Problem noted by Eric Lee of Talking Heads.
New Files:
devtools/OS/Darwin.7.0
convert .fig files to Postscript, PDF, and the like. This is not
a dependency, because transfig can be used without Ghostscript as
well (eg, to convert to other file formats). Moreover, it is a
pre-requisite to Xfig, which doesn't require Ghostscript at all.
Closes PR pkg/22959 by Greg A. Woods <woods@planix.com>
Changes:
Added continue to keyword list.
Added use contributed matlab-generate-latex command.
Doc comment update (New file exchange link, matlab shell switches)
Font lock of pragmas
Whitespace mode support.
Exclude block verify from save hooks.
Fixed if statement regexp for unreachable code.
Add persistent as a keyword.
Fill paragraph: Fix to handle comment at end of buffer.
matlab-shell: Fix where kill-local-variables is called.
User patch for finding the symbol at point.
Yoni Wexler contributed patch for indented tic/toc.
Block highlighting tic/toc.
font lock for tic toc.
If we're going to mess with defining FLOAT on the command line
(done for alpha from before), we should also define FLOAT_MAX.
Pull in <float.h> in libmp3lib/machine.h, so that DBL_MAX is
available for that purpose.
