.Os
.Sh NAME
.Nm editline
.Nd line editing user interface
.Sh DESCRIPTION
When a program using the
.Xr editline 3
library prompts for an input string using the function
.Xr el_wgets 3 ,
it reads characters from the terminal.
Invalid input bytes that do not form characters are silently
discarded.
For each character read, one editor command is executed.
The mapping of input characters to editor commands depends on the
editing mode.
There are three editing modes: vi insert mode, vi command mode,
and emacs mode.
The default is vi insert mode.
The program can switch the default to emacs mode by using the
.Xr el_set 3
or
.Xr el_parse 3
functions, and the user can switch to emacs mode either in the
.Xr editrc 5
configuration file or interactively with the
.Ic ed-command
editor command, in all three cases executing the
.Ic bind Fl e
builtin command.
.Pp
If trying to read from the terminal results in end of file or an
error, the library signals end of file to the program and does not
return a string.
.Ss Input character bindings
All default bindings described below can be overridden by individual
programs and can be changed with the
.Xr editrc 5
.Ic bind
builtin command.
.Pp
In the following tables,
.Sq Ctrl-
indicates a character with the bit 0x40 flipped, and
.Sq Meta-
indicates a character with the bit 0x80 set.
In vi insert mode and in emacs mode, all Meta-characters considered
printable by the current
.Xr locale 1
are bound to
.Ic ed-insert
instead of to the editor command listed below.
Consequently, in UTF-8 mode, most of the Meta-characters are not
directly accessible because their code points are occupied by
printable Unicode characters, and Meta-characters are usually input
using the
.Ic em-meta-next
editor command.
For example, to enter
.Sq Meta-B
in order to call the
.Ic ed-prev-word
editor command in emacs mode, call
.Ic em-meta-next
by pressing and releasing the escape key (or equivalently, Ctrl-[),
then press and release the
.Sq B
key.
If you have configured a Meta-key on your keyboard, for example
with
.Ql setxkbmap -option altwin:left_meta_win ,
the Ctrl-Meta-characters are directly accessible.
For example, to enter
.Sq Ctrl-Meta-H
in order to call the
.Ic ed-delete-prev-word
editor command in emacs mode, hold down the keys
.Sq Ctrl ,
.Sq Meta ,
and
.Sq H
at the same time.
Alternatively, press and release the escape key, then press and
release
.Sq Ctrl-H .
.Pp
In vi input mode, input characters are bound to the following editor
commands by default:
.Bl -column -offset indent "Ctrl-Z, TSTP" "ed-search-next-history"
.It Ctrl-D, EOF Ta Ic vi-list-or-eof
.It Ctrl-H, BS Ta Ic vi-delete-prev-char

.It Ctrl-[, ESC Ta Ic vi-command-mode
.It Ctrl-\e, QUIT Ta Ic ed-tty-sigquit
.It Ctrl-?, DEL Ta Ic vi-delete-prev-char
.El
.Pp
All other input characters except the NUL character (Ctrl-@) are
bound to
.Ic ed-insert .

In vi command mode, input characters are bound to the following
editor commands by default:
.Bl -column -offset indent "Ctrl-Z, TSTP" "ed-search-next-history"
.It Ctrl-A Ta Ic ed-move-to-beg
.It Ctrl-C, INT Ta Ic ed-tty-sigint

The remaining

characters in the range 0x20 to 0x7e are bound to
.Ic ed-insert .
.Pp
If standard output is not connected to a terminal device
or
.Xr el_set 3
was used to set
.Dv EL_EDITMODE
to 0, all input character bindings are disabled and all characters
typed are appended to the edit buffer.
In that case, the edit buffer is returned to the program after a
newline or carriage return character is typed, or after the first
character typed if
.Xr el_set 3
was used to set
.Dv EL_UNBUFFERED
to non-zero.
.Ss Editor commands
Most editor commands accept an optional argument.
The argument is entered by prefixing the editor command with one
or more of the editor commands
.Ic ed-argument-digit ,
.Ic ed-digit ,
.Ic em-universal-argument ,
or
.Ic vi-zero .
When an argument is not provided, it defaults to 1.
For most editor commands, the effect of an argument is to repeatedly
execute the command that number of times.
.Pp
When talking about a character string from a left character to a
right character, the left character is included in the string, while
the right character is not included.
.Pp
If an editor command causes an error, the input character is discarded,
no action occurs, and the terminal bell is rung.
In case of a non-fatal error, the terminal bell is also rung,
but the editor command takes effect anyway.
.Pp
In the following list, the default key bindings are listed after
each editor command.

.Ss Macros
If an input character is bound to the editor command
.Ic ed-sequence-lead-in ,
.Nm
attempts to call a macro.
If the input character by itself forms the name of a macro, that
macro is executed.
Otherwise, additional input characters are read until the string
read forms the name of a macro, in which case that macro is executed,
or until the string read matches the beginning of none of the existing
macro names, in which case the string including the final, mismatching
character is discarded and the terminal bell is rung.
.Pp
There are two kinds of macros.
Command macros execute a single editor command.
Keyboard macros return a string of characters that is appended
as a new line to the
.Sx Input Queue .
.Pp
The following command macros are defined by default in vi command

.Bl -column -offset indent "Esc O A, Esc O A" "em-exchange-mark"

.It Esc \&[ D, Esc O D Ta Ic ed-prev-char
.It Esc \&[ F, Esc O F Ta Ic ed-move-to-end
.It Esc \&[ H, Esc O H Ta Ic ed-move-to-beg
.El
.Pp
In vi command mode, they are also defined by default without the
initial escape character.
.Pp
In addition, the
.Nm
library tries to bind the strings generated by the arrow keys
as reported by the
.Xr terminfo 5
database to these editor commands, unless that would clobber
user settings.
.Pp
In emacs mode, the two-character string
.Dq Ctrl-X Ctrl-X
is bound to the
.Ic em-exchange-mark
editor command.
.Ss Input Queue
The
.Nm
library maintains an input queue operated in FIFO mode.
Whenever it needs an input character, it takes the first character
from the first line of the input queue.
When the queue is empty, it reads from the terminal.
.Pp
A line can be appended to the end of the input queue in several ways:
.Bl -dash -offset indent
.It
By calling one of the keyboard
.Sx Macros .
.It
By calling the editor command
.Ic vi-redo .
.It
By calling the editor command
.Ic vi-alias .
.It
By pressing a key in emacs incremental search mode that doesn't
have a special meaning in that mode but returns to normal emacs
mode.
.It
If an application program directly calls the functions
.Xr el_push 3
or
.Xr el_wpush 3 ,
it can provide additional, program-specific ways
of appending to the input queue.

.Sh NAME
.Nm editrc
.Nd configuration file for editline library
.Sh SYNOPSIS
.Nm
.Sh DESCRIPTION
The
.Nm
file defines various settings to be used by the
.Xr editline 3
library.
.Pp
The format of each line is:
.Pp
.Dl [prog:]command [arg ...]
.Pp
.Ar command
is one of the
.Xr editline 3
builtin commands.
Refer to
.Sx BUILTIN COMMANDS
for more information.
.Pp
.Ar prog
is the program name string that a program defines when it calls
.Xr el_init 3
to set up
.Xr editline 3 ,
which is usually
.Va argv[0] .
.Ar command
will be executed for any program which matches
.Ar prog .
.Pp
.Ar prog
may also be a
.Xr regex 3
style
regular expression, in which case
.Ar command
will be executed for any program that matches the regular expression.
.Pp
If
.Ar prog
is absent,
.Ar command
is executed for all programs.
.Sh BUILTIN COMMANDS
The
.Nm editline
library has some builtin commands, which affect the way
that the line editing and history functions operate.
These are based on similar named builtins present in the
.Xr tcsh 1
shell.
.Pp
The following builtin commands are available:
.Bl -tag -width 4n
.It Ic bind Oo Fl aeklrsv Oc Op Ar key Op Ar command
Without options and arguments, list all bound keys and macros, and
the editor command or input string to which each one is bound.
If only
.Ar key
is supplied, show the binding for that key or macro.
If
.Ar key command
is supplied, bind the editor
.Ar command
to that key or macro.
.Pp
The options are as follows:
.Bl -tag -width 4n
.It Fl a
List or change key bindings in the
.Xr vi 1
mode alternate (command mode) key map.
.It Fl e
Bind all keys to the standard GNU Emacs-like bindings.
.It Fl k
.Ar key
is interpreted as a symbolic arrow key name, which may be one of
.Sq up ,
.Sq down ,
.Sq left
or
.Sq right .
.It Fl l
List all editor commands and a short description of each.
.It Fl r
Remove the binding of the key or macro
.Ar key .
.It Fl s
Define a keyboard macro rather than a key binding or command macro:
.Ar command
is taken as a literal string and appended to the input queue whenever
.Ar key
is typed.
Bound keys and macros in
.Ar command
are themselves reinterpreted, and this continues for ten levels of
interpretation.
.It Fl v
Bind all keys to the standard
.Xr vi 1 Ns -like
bindings.
.El
.Pp
The
.Xr editline 7
manual documents all editor commands and contains more information
about macros and the input queue.
.Pp
.Ar key
and
.Ar command
can contain control characters of the form
.Sm off
.Sq No ^ Ar character
.Sm on
.Po
e.g.\&
.Sq ^A
.Pc ,
and the following backslashed escape sequences:
.Pp
.Bl -tag -compact -offset indent -width 4n
.It Ic \ea
Bell
.It Ic \eb
Backspace
.It Ic \ee
Escape
.It Ic \ef
Formfeed
.It Ic \en
Newline
.It Ic \er
Carriage return
.It Ic \et
Horizontal tab
.It Ic \ev
Vertical tab
.Sm off
.It Sy \e Ar nnn
.Sm on
The ASCII character corresponding to the octal number
.Ar nnn .
.El
.Pp
.Sq \e
nullifies the special meaning of the following character,
if it has any, notably
.Sq \e
and
.Sq ^ .
.It Ic echotc Oo Fl sv Oc Ar arg Ar ...
Exercise terminal capabilities given in
.Ar arg ... .
If
.Ar arg
is
.Sq baud ,
.Sq cols ,
.Sq lines ,
.Sq rows ,
.Sq meta ,
or
.Sq tabs ,
the value of that capability is printed, with
.Dq yes
or
.Dq no
indicating that the terminal does or does not have that capability.
.Pp
.Fl s
returns an empty string for non-existent capabilities, rather than
causing an error.
.Fl v
causes messages to be verbose.
.It Ic edit Op Li on | Li off
Enable or disable the
.Nm editline
functionality in a program.
.It Ic history Ar list | Ar size Dv n | Ar unique Dv n
The
.Ar list
command lists all entries in the history.
The
.Ar size
command sets the history size to
.Dv n
entries.
The
.Ar unique
command controls if history should keep duplicate entries.
If
.Dv n
is non zero, only keep unique history entries.
If
.Dv n
is zero, then keep all entries (the default).
.It Ic settc Ar cap Ar val
Set the terminal capability
.Ar cap
to
.Ar val ,
as defined in
.Xr termcap 5 .
No sanity checking is done.
.It Ic setty Oo Fl a Oc Oo Fl d Oc Oo Fl q Oc Oo Fl x Oc Oo Ar +mode Oc \
Oo Ar -mode Oc Oo Ar mode Oc Oo Ar char=c Oc
Control which tty modes that
.Nm
won't allow the user to change.
.Fl d ,
.Fl q
or
.Fl x
tells
.Ic setty
to act on the
.Sq edit ,
.Sq quote
or
.Sq execute
set of tty modes respectively; defaulting to
.Fl x .
.Pp
Without other arguments,
.Ic setty
lists the modes in the chosen set which are fixed on
.Po
.Sq +mode
.Pc
or off
.Po
.Sq -mode
.Pc .
.Fl a
lists all tty modes in the chosen set regardless of the setting.
With
.Ar +mode ,
.Ar -mode
or
.Ar mode ,
fixes
.Ar mode
on or off or removes control of
.Ar mode
in the chosen set.
.Pp
.Ic Setty
can also be used to set tty characters to particular values using
.Ar char=value .
If
.Ar value
is empty
then the character is set to
.Dv _POSIX_VDISABLE .
.It Ic telltc
List the values of all the terminal capabilities (see
.Xr termcap 5 ) .
.El
.Sh ENVIRONMENT
.Bl -tag -width "~/.editrcXXX"
.It Ev EDITRC
Names the default configuration file for the
.Xr editline 3
library.
.El
.Sh FILES
.Bl -tag -width "~/.editrcXXX"
.It Pa ~/.editrc
Last resort, if no other file is specified,
user configuration file for the
.Xr editline 3
library.

Release 2019c - 2019-09-11 08:59:48 -0700
Briefly:
Fiji observes DST from 2019-11-10 to 2020-01-12.
Norfolk Island starts observing Australian-style DST.
Changes to future timestamps
Fiji's next DST transitions will be 2019-11-10 and 2020-01-12
instead of 2019-11-03 and 2020-01-19. (Thanks to Raymond Kumar.)
Adjust future guesses accordingly.
Norfolk Island will observe Australian-style DST starting in
spring 2019. The first transition is on 2019-10-06. (Thanks to
Kyle Czech and Michael Deckers.)
Changes to past timestamps
Many corrections to time in Turkey from 1940 through 1985.
(Thanks to Oya Vulaş via Alois Treindl, and to Kıvanç Yazan.)
The Norfolk Island 1975-03-02 transition was at 02:00 standard
time, not 02:00 DST. (Thanks to Michael Deckers.)
South Korea observed DST from 1948 through 1951. Although this
info was supposed to appear in release 2014j, a typo inadvertently
suppressed the change. (Thanks to Alois Treindl.)
Detroit observed DST in 1967 and 1968 following the US DST rules,
except that its 1967 DST began on June 14 at 00:01. (Thanks to
Alois Treindl for pointing out that the old data entries were
probably wrong.)
Fix several errors in pre-1970 transitions in Perry County, IN.
(Thanks to Alois Triendl for pointing out the 1967/9 errors.)
Edmonton did not observe DST in 1967 or 1969. In 1946 Vancouver
ended DST on 09-29 not 10-13, and Vienna ended DST on 10-07 not
10-06. In 1945 Königsberg (now Kaliningrad) switched from +01/+02
to +02/+03 on 04-10 not 01-01, and its +02/+03 is abbreviated
EET/EEST, not CET/CEST. (Thanks to Alois Triendl.) In 1946
Königsberg switched to +03 on 04-07 not 01-01.
In 1946 Louisville switched from CST to CDT on 04-28 at 00:01, not
01-01 at 00:00. (Thanks to Alois Treindl and Michael Deckers.)
Also, it switched from CST to CDT on 1950-04-30, not 1947-04-27.
The 1892-05-01 transition in Brussels was at 00:17:30, not at noon.
(Thanks to Michael Deckers.)
Changes to past time zone abbreviations and DST flags
Hong Kong Winter Time, observed from 1941-10-01 to 1941-12-25,
is now flagged as DST and is abbreviated HKWT not HKT.
Changes to code
leapseconds.awk now relies only on its input data, rather than
also relying on its comments. (Inspired by code from Dennis
Ferguson and Chris Woodbury.)
The code now defends against CRLFs in leap-seconds.list.
(Thanks to Brian Inglis and Chris Woodbury.)
Changes to documentation and commentary
theory.html discusses leap seconds. (Thanks to Steve Summit.)
Nashville's newspapers dueled about the time of day in the 1950s.
(Thanks to John Seigenthaler.)
Liechtenstein observed Swiss DST in 1941/2.
(Thanks to Alois Treindl.)

# like the entire French Indochina, used Tokyo time zone. After Japan

# Assume this practice predates 1970, so Fort Pierre can use America/Chicago.
# From Paul Eggert (2015-04-06):
# In 1950s Nashville a public clock had dueling faces, one for conservatives
# and the other for liberals; the two sides didn't agree about the time of day.
# I haven't found a photo of this clock, nor have I tracked down the TIME
# magazine report cited below, but here's the story as told by the late
# American journalist John Seigenthaler, who was there:
#
# "The two [newspaper] owners held strongly contrasting political and
# ideological views. Evans was a New South liberal, Stahlman an Old South
# conservative, and their two papers frequently clashed editorially, often on
# the same day.... In the 1950s as the state legislature was grappling with
# the question of whether to approve daylight saving time for the entire state,
# TIME magazine reported:
#
# "'The Nashville Banner and The Nashville Tennessean rarely agree on anything
# but the time of day - and last week they couldn't agree on that.'
#
# "It was all too true. The clock on the front of the building had two faces -
# The Tennessean side of the building facing west, the other, east. When it
# was high noon Banner time, it was 11 a.m. Tennessean time."
#
# Seigenthaler J. For 100 years, Tennessean had it covered.

# 1967-06-14, in an article "State Adjusting to Switch to Fast Time"
# by Gary Blonston, above an article about Thurgood Marshall's
# confirmation to the US Supreme Court. Although Shanks says Detroit
# observed DST until 1967-10-29 00:01, that time of day seems to be
# incorrect, as the Free Press later said DST ended in Michigan at the
# same time as the rest of the US. Also, although Shanks reports no DST in
# Detroit in 1968, it did observe DST that year; in the November 1968
# election Michigan voters narrowly repealed DST, effective 1969.

<h2 id="leapsec">Leap seconds</h2>
<p>
The <code><abbr>tz</abbr></code> code and data can account for leap seconds,
thanks to code contributed by Bradley White.
However, the leap second support of this package is rarely used directly
because POSIX requires leap seconds to be excluded and many
software packages would mishandle leap seconds if they were present.
Instead, leap seconds are more commonly handled by occasionally adjusting
the operating system kernel clock as described in
<a href="tz-link.html#precision">Precision timekeeping</a>,
and this package by default installs a <samp>leapseconds</samp> file
commonly used by
<a href="http://www.ntp.org"><abbr title="Network Time Protocol">NTP</abbr></a>
software that adjusts the kernel clock.
However, kernel-clock twiddling approximates UTC only roughly,
and systems needing more-precise UTC can use this package's leap
second support directly.
</p>
<p>
The directly-supported mechanism assumes that <code>time_t</code>
counts of seconds since the POSIX epoch normally include leap seconds,
as opposed to POSIX <code>time_t</code> counts which exclude leap seconds.
This modified timescale is converted to <abbr>UTC</abbr>
at the same point that time zone and DST adjustments are applied &ndash;
namely, at calls to <code>localtime</code> and analogous functions &ndash;
and the process is driven by leap second information
stored in alternate versions of the <abbr>TZif</abbr> files.
Because a leap second adjustment may be needed even
if no time zone correction is desired,
calls to <code>gmtime</code>-like functions
also need to consult a <abbr>TZif</abbr> file,
conventionally named <samp><abbr>GMT</abbr></samp>,
to see whether leap second corrections are needed.
To convert an application's <code>time_t</code> timestamps to or from
POSIX <code>time_t</code> timestamps (for use when, say,
embedding or interpreting timestamps in portable
<a href="https://en.wikipedia.org/wiki/Tar_(computing)"><code>tar</code></a>
files),
the application can call the utility functions
<code>time2posix</code> and <code>posix2time</code>
included with this package.
</p>
<p>
If the POSIX-compatible <abbr>TZif</abbr> file set is installed
in a directory whose basename is <samp>zoneinfo</samp>, the
leap-second-aware file set is by default installed in a separate
directory <samp>zoneinfo-leaps</samp>.
Although each process can have its own time zone by setting
its <code>TZ</code> environment variable, there is no support for some
processes being leap-second aware while other processes are
POSIX-compatible; the leap-second choice is system-wide.
So if you configure your kernel to count leap seconds, you should also
discard <samp>zoneinfo</samp> and rename <samp>zoneinfo-leaps</samp>
to <samp>zoneinfo</samp>.
Alternatively, you can install just one set of <abbr>TZif</abbr> files
in the first place; see the <code>REDO</code> variable in this package's
<a href="https://en.wikipedia.org/wiki/Makefile">makefile</a>.

https://github.com/openssl/openssl/commits/ and pick the appropriate
release branch.
Changes between 1.1.1c and 1.1.1d [10 Sep 2019]
*) Fixed a fork protection issue. OpenSSL 1.1.1 introduced a rewritten random
number generator (RNG). This was intended to include protection in the
event of a fork() system call in order to ensure that the parent and child
processes did not share the same RNG state. However this protection was not
being used in the default case.
A partial mitigation for this issue is that the output from a high
precision timer is mixed into the RNG state so the likelihood of a parent
and child process sharing state is significantly reduced.
If an application already calls OPENSSL_init_crypto() explicitly using
OPENSSL_INIT_ATFORK then this problem does not occur at all.
(CVE-2019-1549)
[Matthias St. Pierre]
*) For built-in EC curves, ensure an EC_GROUP built from the curve name is
used even when parsing explicit parameters, when loading a serialized key
or calling `EC_GROUP_new_from_ecpkparameters()`/
`EC_GROUP_new_from_ecparameters()`.
This prevents bypass of security hardening and performance gains,
especially for curves with specialized EC_METHODs.
By default, if a key encoded with explicit parameters is loaded and later
serialized, the output is still encoded with explicit parameters, even if
internally a "named" EC_GROUP is used for computation.
[Nicola Tuveri]
*) Compute ECC cofactors if not provided during EC_GROUP construction. Before
this change, EC_GROUP_set_generator would accept order and/or cofactor as
NULL. After this change, only the cofactor parameter can be NULL. It also
does some minimal sanity checks on the passed order.
(CVE-2019-1547)
[Billy Bob Brumley]
*) Fixed a padding oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey.
An attack is simple, if the first CMS_recipientInfo is valid but the
second CMS_recipientInfo is chosen ciphertext. If the second
recipientInfo decodes to PKCS #1 v1.5 form plaintext, the correct
encryption key will be replaced by garbage, and the message cannot be
decoded, but if the RSA decryption fails, the correct encryption key is
used and the recipient will not notice the attack.
As a work around for this potential attack the length of the decrypted
key must be equal to the cipher default key length, in case the
certifiate is not given and all recipientInfo are tried out.
The old behaviour can be re-enabled in the CMS code by setting the
CMS_DEBUG_DECRYPT flag.
(CVE-2019-1563)
[Bernd Edlinger]
*) Early start up entropy quality from the DEVRANDOM seed source has been
improved for older Linux systems. The RAND subsystem will wait for
/dev/random to be producing output before seeding from /dev/urandom.
The seeded state is stored for future library initialisations using
a system global shared memory segment. The shared memory identifier
can be configured by defining OPENSSL_RAND_SEED_DEVRANDOM_SHM_ID to
the desired value. The default identifier is 114.
[Paul Dale]
*) Correct the extended master secret constant on EBCDIC systems. Without this
fix TLS connections between an EBCDIC system and a non-EBCDIC system that
negotiate EMS will fail. Unfortunately this also means that TLS connections
between EBCDIC systems with this fix, and EBCDIC systems without this
fix will fail if they negotiate EMS.
[Matt Caswell]
*) Use Windows installation paths in the mingw builds
Mingw isn't a POSIX environment per se, which means that Windows
paths should be used for installation.
(CVE-2019-1552)
[Richard Levitte]
*) Changed DH_check to accept parameters with order q and 2q subgroups.
With order 2q subgroups the bit 0 of the private key is not secret
but DH_generate_key works around that by clearing bit 0 of the
private key for those. This avoids leaking bit 0 of the private key.
[Bernd Edlinger]
*) Significantly reduce secure memory usage by the randomness pools.
[Paul Dale]
*) Revert the DEVRANDOM_WAIT feature for Linux systems
The DEVRANDOM_WAIT feature added a select() call to wait for the
/dev/random device to become readable before reading from the
/dev/urandom device.
It turned out that this change had negative side effects on
performance which were not acceptable. After some discussion it
was decided to revert this feature and leave it up to the OS
resp. the platform maintainer to ensure a proper initialization
during early boot time.

(CVE-2019-1543)
[Matt Caswell]
*) Add DEVRANDOM_WAIT feature for Linux systems
On older Linux systems where the getrandom() system call is not available,
OpenSSL normally uses the /dev/urandom device for seeding its CSPRNG.
Contrary to getrandom(), the /dev/urandom device will not block during
early boot when the kernel CSPRNG has not been seeded yet.
To mitigate this known weakness, use select() to wait for /dev/random to
become readable before reading from /dev/urandom.
