Changes to Bash + +a. Fixed a bug that caused a posix-mode shell to not exit if the return builtin + was executed outside a function or dot script. + +b. Fixed a bug where `declare +f' could potentially turn off the function + attribute. + +c. Restored bash-4.4 pathname expansion behavior when a word to be expanded had + only backslashes, not any of the other globbing characters. This came after + an extensive POSIX group discussion (interp #1234). + +d. There are more changes to avoid performing word expansions multiple times on + arithmetic expressions. + +e. Fixed a bug with alias expansion when the alias ends with a TAB. + +f. Fixed a bug that caused programmable completion to return an error if the + shell function name supplied as an argument to `complete -F' was invalid. + +g. There are several fixes to buffer overflows found as the result of fuzzing + with random input. + +h. Fixed a bug that caused the edit-and-execute-command editing command to + start with the previous history line if invoked on an empty line. + +i. Fixed a bug that potentially caused `bind --help' to change readline's + output stream. + +j. Turning off posix mode now restores the vi-insertion mode binding for TAB + that was in effect when posix mode was enabled. + +k. Restore the previous state of job control being enabled if `exec' fails in + an interactive shell. + +l. Fixed a bug that caused the terminal's process group to be set incorrectly + if job control was turned off before starting an interactive shell. + +m. Fixed a bug that caused a crash when HISTSIZE=0. + +n. Fixed a word expansion bug that caused null strings on the rhs of expansions + to be discarded incorrectly. + +o. History list management does a better job of handling the situation where + the number of history entries from the current shell session is greater than + the number of entries in the history list. + +p. Fixed a bug that caused the `fc' builtin to attempt to dereference a newly- + freed history entry. + +q. Fixed a bug that made the `Q' variable transformation not work well with + `set -u'. + +r. There are several word expansion fixes for expanding $* and $@ in contexts + where word splitting is not going to be performed, since each positional + parameter must expand to a separate word. + +s. Fixed a bug that could cause ^D to exit bash immediately even if there were + stopped jobs. + +t. Fixed a bug with double-quoting and backslash-quoting strings containing + multibyte characters for reuse. + +u. Fixed a bug that caused the line number to be reported incorrectly if the + shell executed a (command) subshell. + +v. Fixed a bug that caused the shell to fail to reap process substitutions + when they went out of scope, which had unpredictable results. + +w. Fixed a bug that caused null strings in arguments to [[ conditional command + operators to compare incorrectly. + +x. Changed the behavior of `wait' without arguments to only wait for background + processes the current shell instance started, not background children it may + have inherited. + +y. Fixed a bug that could cause command substitution to leave file descriptors + open if the shell received many SIGINTs. + +z. Bash now behaves better if the `**' filename expansion operator encounters a + symbolic link to a directory, avoiding more cases where it might return + duplicate pathnames. + +aa. Programmable completion now canonicalizes directory names in the same way + as bash word completion, so `..' is handled consistently. + +bb. Fixed a bug when using RETURN as the delimiter to the read builtin; it + caused readline to set the binding for RETURN incorrectly. + +cc. Fixed a bug that caused `history -d' to delay printing an out-of-range + error message. + +dd. Fixed a bug with `bash -c command' where `command' ends with an expanded + alias. + +ee. Fixed a bug that could result in `history -n' adding spurious line feeds to + commands in the history list. + +ff. The $RANDOM random number generator now XORs the top and bottom halves of + the internal 32-bit value to introduce more randomness. Setting the shell + compatibility level to 50 or lower undoes this. + +gg. Fixed several problems caused by running the DEBUG trap on simple commands + executed as part of a pipeline. + +ii. Fixed a bug that didn't allow `bind -r' to remove the binding for \C-@. + +jj. Several fixes to the bash-backward-shellword bindable readline command to + behave better when at the last character on the line. + +kk. If `set -x' is enabled, bash doesn't print a command twice if it's run by + the `command' builtin. + +ll. Fixed a bug with printing function definitions containing here documents. + +mm. Fixed a bug that could cause the `bind' builtin to set $? to -1. + +nn. Fixed a bug that didn't reset the timezone information correctly when the + TZ variable was unset. + +oo. Fixed several issues with assigning an associative array variable using a + compound assignment that expands the value of the same variable. + +pp. Fixed several places where the shell set $? without setting PIPESTATUS. + +qq. Fixed a problem with glob bracket expressions containing invalid character + classes, collating symbols, or equivalence classes -- they should not + require a closing right bracket. + +rr. Fixed a bug where running a builtin in a subshell did not run the EXIT trap. + +ss. Fixed several problems with posix-mode variable assignments preceding + shell function calls and posix special builtins, so that they create and + modify variables at the current scope. + +tt. Fix history initialization so `bash +o history' works as expected. + +uu. Fixed a bug in the bindable edit-and-execute-command command that could + interfere with the shell's parsing state. + +vv. Fixed an issue with nested traps running command substitutions in command + lines with command substitutions. + +ww. Fixed a bug with globbing pathnames that contain invalid multibyte + characters (sequences that don't correspond to a character in the current + locale). + +xx. Fixed a bug that caused the shell not to exit if a function definition + failed while errexit was enabled. + +yy. Process substitution processes now get their input from /dev/null, since + they are asynchronous, not interactive, and not jobs. + +zz. Setting nocaseglob no longer turns on case-insensitive regexp matching. + +aaa. Fixed a bug that resulted in extra blank lines being added to some history + entries containing here-documents. + +bbb. Fixed a bug that resulted in incorrect matching of some patterns in word + expansion if they expanded to the empty string. + +ccc. Fixed here-string expansion so it behaves the same as expansion of the + rhs of an assignment statement. + +ddd. Changed here-document parsing to no longer allow the end of the here + document to delimit a command substitution. + +eee. Several fixes to history expansion: multiple :p modifiers work, a ^ word + designator works as part of a range, and a `-' is treated as part of a + search string if it immediately follows a `!'. + +fff. Fixed a bug in pattern substitution with null matches in a string + containing multibyte characters. + +ggg. Unbinding a key sequence bound with `bind -x' now removes the key sequence + from the additional keymap `bind -x' uses. + +hhh. Fixed a bug with command start detection for completion so that it doesn't + mistake brace expansion for the start of a command. + +iii. Fixed a bug that caused local variables with the same name as variables + appearing in a function's temporary environment to not be marked as local. + +jjj. Fixed a bug that could cause SIGCHLD to be blocked when executing return + or exec in the rightmost pipeline element with lastpipe enabled. + +kkk. Fixed a bug that could result in commands without the execute bit set + being added to the command hash table. + +lll. Fixed a bug that allowed non-digits to follow the `#' in a `base#number' + integer constant. + +mmm. Fixed a bug that made `time -- command' attempt to execute `--'. + +nnn. Fixed a couple of bugs with variable transformation using arrays + subscripted with `*' or `@'. + +ooo. A failure to create a variable using `declare' in a function no longer + causes the function to return immediately. + +ppp. Fixed a bug that could cause the := word expansion to add a non-null + value if attempting to assign a null string when double-quoted. + +qqq. Fixed a bug that could cause backslashes quoting double quotes in here + document bodies to not be removed when expanding the body. + +rrr. Fixed a bug that caused commands following a subshell while the shell is + reading input from stdin but not interactive, while job control is + enabled, to be executed twice. + +sss. Fixed a bug where receiving SIGTERM from a different process while + readline was active could cause the shell to terminate. + +ttt. In posix mode, running a trap after the read builtin now sees the exit + status of the read builtin (e.g., 130 after a SIGINT) in $?. + +uuu. Fixed a bug with nameref variables referencing array subscripts used in + arithmetic expressions. + +vvv. Fixed a bug that caused the pipeline process group id to be reset in the + middle of a command list run by a shell started to run a command + substitution. + +www. Restricted shells can no longer read and write history files with pathnames + containing slashes. + +xxx. Fixed a couple of problems with 0 and -0 used as arguments to `fc' when + not listing commands from the history. + +yyy. When `test' is supplied four or more arguments, treat an argument that + looks like an operator (e.g., -e), but is in a place where only a string + is valid, as a string, as it would be when using the POSIX rules, instead + of an operator with a missing argument. + +zzz. There is no `compat50' shopt option. Changes to the shell compatibility + level should use the BASH_COMPAT variable. + +aaaa. Redirection failures with compound commands are now treated as errors + that cause the shell to exit if `errexit' is enabled. + +bbbb. Redirection failure error messages no longer expand the word in the + redirection again. + +cccc. History expansion is no longer performed while parsing a here-document + inside a command substitution. + +2. Changes to Readline + +a. There are a number of fixes that were found as the result of fuzzing with + random input. + +b. Changed the revert-all-at-newline behavior to make sure to start at the end + of the history list when doing it, instead of the line where the user hit + return. + +c. When parsing `set' commands from the inputrc file or an application, readline + now allows trailing whitespace. + +d. Fixed a bug that left a file descriptor open to the history file if the + file size was 0. + +e. Fixed a problem with binding key sequences containing meta characters. + +f. Fixed a bug that caused the wrong line to be displayed if the user tried to + move back beyond the beginning of the history list, or forward past the end + of the history list. + +g. If readline catches SIGTSTP, it now sets a hook that allows the calling + application to handle it if it desires. + +h. Fixed a redisplay problem with a prompt string containing embedded newlines. + +i. Fixed a problem with completing filenames containing invalid multibyte + sequences when case-insensitive comparisons are enabled. + +j. Fixed a redisplay problem with prompt strings containing invisible multibyte + characters. + +k. Fixed a problem with multibyte characters mapped to editing commands that + modify the search string in incremental search. + +l. Fixed a bug with maintaining the key sequence while resolving a bound + command in the presence of ambiguous sequences (sequences with a common + prefix), in most cases while attempting to unbind it. + +m. Fixed several buffer overflows found as the result of fuzzing. + +n. Reworked backslash handling when translating key sequences for key binding + to be more uniform and consistent, which introduces a slight backwards + incompatibility. + +o. Fixed a bug with saving the history that resulted in errors not being + propagated to the calling application when the history file is not writable. + +p. Readline only calls chown(2) on a newly-written history file if it really + needs to, instead of having it be a no-op. + +q. Readline now behaves better when operate-and-get-next is used when the + history list is `full': when there are already $HISTSIZE entries. + +r. Fixed a bug that could cause vi redo (`.') of a replace command not to work + correctly in the C or POSIX locale. + +3. New Features in Bash + +a. `bind -x' now supports different bindings for different editing modes and + keymaps. + +b. Bash attempts to optimize the number of times it forks when executing + commands in subshells and from `bash -c'. + +c. Here documents and here strings now use pipes for the expanded document if + it's smaller than the pipe buffer size, reverting to temporary files if it's + larger. + +d. There are new loadable builtins: mktemp, accept, mkfifo, csv, cut/lcut + +e. In posix mode, `trap -p' now displays signals whose disposition is SIG_DFL + and those that were SIG_IGN when the shell starts. + +f. The shell now expands the history number (e.g., in PS1) even if it is not + currently saving commands to the history list. + +g. `read -e' may now be used with arbitrary file descriptors (`read -u N'). + +h. The `select' builtin now runs traps if its internal call to the read builtin + is interrupted by a signal. + +i. SRANDOM: a new variable that expands to a 32-bit random number that is not + produced by an LCRNG, and uses getrandom/getentropy, falling back to + /dev/urandom or arc4random if available. There is a fallback generator if + none of these are available. + +j. shell-transpose-words: a new bindable readline command that uses the same + definition of word as shell-forward-word, etc. + +k. The shell now adds default bindings for shell-forward-word, + shell-backward-word, shell-transpose-words, and shell-kill-word. + +l. Bash now allows ARGV0 appearing in the initial shell environment to set $0. + +m. If `unset' is executed without option arguments, bash tries to unset a shell + function if a name argument cannot be a shell variable name because it's not + an identifier. + +n. The `test -N' operator uses nanosecond timestamp granularity if it's + available. + +o. Bash posix mode now treats assignment statements preceding shell function + definitions the same as in its default mode, since POSIX has changed and + no longer requires those assignments to persist after the function returns + (POSIX interp 654). + +p. BASH_REMATCH is no longer readonly. + +q. wait: has a new -p VARNAME option, which stores the PID returned by `wait -n' + or `wait' without arguments. + +r. Sorting the results of pathname expansion now uses byte-by-byte comparisons + if two strings collate equally to impose a total order; the result of a + POSIX interpretation (#963 and #1070). + +s. Bash now allows SIGINT trap handlers to execute recursively. + +t. Bash now saves and restores state around setting and unsetting posix mode, + instead of having unsetting posix mode set a known state. + +u. Process substitution is now available in posix mode. + +v. READLINE_MARK: a new variable available while executing commands bound with + `bind -x', contains the value of the mark. + +w. Bash removes SIGCHLD from the set of blocked signals if it's blocked at shell + startup. + +x. `test -v N' can now test whether or not positional parameter N is set. + +y. `local' now honors the `-p' option to display all local variables at the + current context. + +z. The `@a' variable transformation now prints attributes for unset array + variables. + +aa. The `@A' variable transformation now prints a declare command that sets a + variable's attributes if the variable has attributes but is unset. + +bb. `declare' and `local' now have a -I option that inherits attributes and + value from a variable with the same name at a previous scope. + +cc. When run from a -c command, `jobs' now reports the status of completed jobs. + +dd. New `U', `u', and `L' parameter transformations to convert to uppercase, + convert first character to uppercase, and convert to lowercase, + respectively. + +ee. PROMPT_COMMANDS: a new array variable, each element of which can contain a + command to be executed like PROMPT_COMMAND. + +ff. `ulimit' has a -R option to report and set the RLIMIT_RTTIME resource. + +gg. Associative arrays may be assigned using a list of key-value pairs within + a compound assignment. Compound assignments where the words are not of + the form [key]=value are assumed to be key-value assignments. A missing or + empty key is an error; a missing value is treated as NULL. Assignments may + not mix the two forms. + +hh. New `K' parameter transformation to display associative arrays as key- + value pairs. + +ii. Writing history to syslog now handles messages longer than the syslog max + length by writing multiple messages with a sequence number. + +jj. SECONDS and RANDOM may now be assigned using arithmetic expressions, since + they are nominally integer variables. LINENO is not an integer variable. + +kk. Bash temporarily suppresses the verbose option when running the DEBUG trap + while running a command from the `fc' builtin. + +ll. `wait -n' now accepts a list of job specifications as arguments and will + wait for the first one in the list to change state. + +mm. The associative array implementation can now dynamically increase the + size of the hash table based on insertion patterns. + +nn. HISTFILE is now readonly in a restricted shell. + +oo. The bash malloc now returns memory that is 16-byte aligned on 64-bit + systems. + +4. New Features in Readline + +a. If a second consecutive completion attempt produces matches where the first + did not, treat it as a new completion attempt and insert a match as + appropriate. + +b. Bracketed paste mode works in more places: incremental search strings, vi + overstrike mode, character search, and reading numeric arguments. + +c. Readline automatically switches to horizontal scrolling if the terminal has + only one line. + +d. Unbinding all key sequences bound to a particular readline function now + descends into keymaps for multi-key sequences. + +e. rl-clear-display: new bindable command that clears the screen and, if + possible, the scrollback buffer (bound to emacs mode M-C-l by default). + +f. New active mark and face feature: when enabled, it will highlight the text + inserted by a bracketed paste (the `active region') and the text found by + incremental and non-incremental history searches. + +g. Readline sets the mark in several additional commands. + +h. Bracketed paste mode is enabled by default (for now). + +i. Readline tries to take advantage of the more regular structure of UTF-8 + characters to identify the beginning and end of characters when moving + through the line buffer. + +j. The bindable operate-and-get-next command (and its default bindings) are + now part of readline instead of a bash-specific addition. + +------------------------------------------------------------------------------ This document details the changes between this version, bash-5.0-release, and the previous version, bash-5.0-rc1. @@ -79,7 +545,7 @@ d.

In bash-5.1, disabling posix mode attempts to restore the state of several + options that posix mode modifies to the state they had before enabling + posix mode. Previous versions restored these options to default values. + Shell Compatibility Level ========================= Bash-4.0 introduced the concept of a `shell compatibility level', specified -as a set of options to the shopt builtin (compat31, compat32, compat40, -compat41, and compat42 at this writing). There is only one current -compatibility level -- each option is mutually exclusive. This list does not -mention behavior that is standard for a particular version (e.g., setting -compat32 means that quoting the rhs of the regexp matching operator quotes -special regexp characters in the word, which is default behavior in bash-3.2 -and above). - -Bash-4.3 introduces a new shell variable: BASH_COMPAT. The value assigned +as a set of options to the shopt builtin (compat31, compat32, compat40, +compat41, and so on). There is only one current compatibility level -- +each option is mutually exclusive. The compatibility level is intended to +allow users to select behavior from previous versions that is incompatible +with newer versions while they migrate scripts to use current features and +behavior. It's intended to be a temporary solution. + +This section does not mention behavior that is standard for a particular +version (e.g., setting compat32 means that quoting the rhs of the regexp +matching operator quotes special regexp characters in the word, which is +default behavior in bash-3.2 and above). + +If a user enables, say, compat32, it may affect the behavior of other +compatibility levels up to and including the current compatibility level. +The idea is that each compatibility level controls behavior that changed in +that version of bash, but that behavior may have been present in earlier +versions. For instance, the change to use locale-based comparisons with +the `[[' command came in bash-4.1, and earlier versions used ASCII-based +comparisons, so enabling compat32 will enable ASCII-based comparisons as +well. That granularity may not be sufficient for all uses, and as a result +users should employ compatibility levels carefully. Read the documentation +for a particular feature to find out the current behavior. + +Bash-4.3 introduced a new shell variable: BASH_COMPAT. The value assigned to this variable (a decimal version number like 4.2, or an integer corresponding to the compatNN option, like 42) determines the compatibility level. -Bash-4.4 has begun deprecating older compatibility levels. Eventually, the -options will be removed in favor of the BASH_COMPAT variable. +Starting with bash-4.4, bash has begun deprecating older compatibility +levels.

Users should use the BASH_COMPAT variable +on bash-5.0 and later versions. -compat32 set +The following table describes the behavior changes controlled by each +compatibility level setting. The `compatNN' tag is used as shorthand for +setting the compatibility level to NN using one of the following +mechanisms. For versions prior to bash-5.0, the compatibility level may be +set using the corresponding compatNN shopt option. For bash-4.3 and later +versions, the BASH_COMPAT variable is preferred, and it is required for +bash-5.1 and later versions. + +compat31 - the < and > operators to the [[ command do not consider the current locale when comparing strings; they use ASCII ordering + - quoting the rhs of the [[ command's regexp matching operator (=~) + has no special effect -compat40 set +compat32 - the < and > operators to the [[ command do not consider the current locale when comparing strings; they use ASCII ordering - interrupting a command list such as "a ; b ; c" causes the execution - of the entire list to be aborted (in versions before bash-4.0, - interrupting one command in a list caused the next to be executed) - -compat41 set - - interrupting a command list such as "a ; b ; c" causes the execution - of the entire list to be aborted (in versions before bash-4.0, - interrupting one command in a list caused the next to be executed) - - when in posix mode, single quotes in the `word' portion of a - double-quoted parameter expansion define a new quoting context and - are treated specially + of the next command in the list (in bash-4.0 and later versions, + the shell acts as if it received the interrupt, so interrupting + one command in a list aborts the execution of the entire list) -compat42 set +compat40 + - the < and > operators to the [[ command do not consider the current + locale when comparing strings; they use ASCII ordering. + Bash versions prior to bash-4.1 use ASCII collation and strcmp(3); + bash-4.1 and later use the current locale's collation sequence and + strcoll(3). + +compat41 + - in posix mode, `time' may be followed by options and still be + recognized as a reserved word (this is POSIX interpretation 267) + - in posix mode, the parser requires that an even number of single + quotes occur in the `word' portion of a double-quoted ${...} + parameter expansion and treats them specially, so that characters + within the single quotes are considered quoted (this is POSIX + interpretation 221) + +compat42 - the replacement string in double-quoted pattern substitution is not - run through quote removal, as in previous versions - -compat43 set + run through quote removal, as it is in versions after bash-4.2 + - in posix mode, single quotes are considered special when expanding + the `word' portion of a double-quoted ${...} parameter expansion + and can be used to quote a closing brace or other special character + (this is part of POSIX interpretation 221); in later versions, + single quotes are not special within double-quoted word expansions + +compat43 - the shell does not print a warning message if an attempt is made to use a quoted compound assignment as an argument to declare - (declare -a foo='(1 2)') + (declare -a foo='(1 2)').

As always, the manual page (doc/bash.1) is +the place to look for complete descriptions. + +1. New Features in Bash + +a. `bind -x' now supports different bindings for different editing modes and + keymaps. + +b. Bash attempts to optimize the number of times it forks when executing + commands in subshells and from `bash -c'. + +c. Here documents and here strings now use pipes for the expanded document if + it's smaller than the pipe buffer size, reverting to temporary files if it's + larger. + +d. There are new loadable builtins: mktemp, accept, mkfifo, csv, cut/lcut + +e. In posix mode, `trap -p' now displays signals whose disposition is SIG_DFL + and those that were SIG_IGN when the shell starts. + +f. The shell now expands the history number (e.g., in PS1) even if it is not + currently saving commands to the history list. + +g. `read -e' may now be used with arbitrary file descriptors (`read -u N'). + +h. The `select' builtin now runs traps if its internal call to the read builtin + is interrupted by a signal. + +i. SRANDOM: a new variable that expands to a 32-bit random number that is not + produced by an LCRNG, and uses getrandom/getentropy, falling back to + /dev/urandom or arc4random if available. There is a fallback generator if + none of these are available. + +j. shell-transpose-words: a new bindable readline command that uses the same + definition of word as shell-forward-word, etc. + +k. The shell now adds default bindings for shell-forward-word, + shell-backward-word, shell-transpose-words, and shell-kill-word. + +l. Bash now allows ARGV0 appearing in the initial shell environment to set $0. + +m. If `unset' is executed without option arguments, bash tries to unset a shell + function if a name argument cannot be a shell variable name because it's not + an identifier. + +n. The `test -N' operator uses nanosecond timestamp granularity if it's + available. + +o. Bash posix mode now treats assignment statements preceding shell function + definitions the same as in its default mode, since POSIX has changed and + no longer requires those assignments to persist after the function returns + (POSIX interp 654). + +p. BASH_REMATCH is no longer readonly. + +q. wait: has a new -p VARNAME option, which stores the PID returned by `wait -n' + or `wait' without arguments. + +r. Sorting the results of pathname expansion now uses byte-by-byte comparisons + if two strings collate equally to impose a total order; the result of a + POSIX interpretation. + +s. Bash now allows SIGINT trap handlers to execute recursively. + +t. Bash now saves and restores state around setting and unsetting posix mode, + instead of having unsetting posix mode set a known state. + +u. Process substitution is now available in posix mode. + +v. READLINE_MARK: a new variable available while executing commands bound with + `bind -x', contains the value of the mark. + +w. Bash removes SIGCHLD from the set of blocked signals if it's blocked at shell + startup. + +x. `test -v N' can now test whether or not positional parameter N is set. + +y. `local' now honors the `-p' option to display all local variables at the + current context. + +z. The `@a' variable transformation now prints attributes for unset array + variables. + +aa. The `@A' variable transformation now prints a declare command that sets a + variable's attributes if the variable has attributes but is unset. + +bb. `declare' and `local' now have a -I option that inherits attributes and + value from a variable with the same name at a previous scope. + +cc. When run from a -c command, `jobs' now reports the status of completed jobs. + +dd. New `U', `u', and `L' parameter transformations to convert to uppercase, + convert first character to uppercase, and convert to lowercase, + respectively. + +ee. PROMPT_COMMANDS: a new array variable, each element of which can contain a + command to be executed like PROMPT_COMMAND. + +ff. `ulimit' has a -R option to report and set the RLIMIT_RTTIME resource. + +gg. Associative arrays may be assigned using a list of key-value pairs within + a compound assignment. Compound assignments where the words are not of + the form [key]=value are assumed to be key-value assignments. A missing or + empty key is an error; a missing value is treated as NULL. Assignments may + not mix the two forms. + +hh. New `K' parameter transformation to display associative arrays as key- + value pairs. + +ii. Writing history to syslog now handles messages longer than the syslog max + length by writing multiple messages with a sequence number. + +jj. SECONDS and RANDOM may now be assigned using arithmetic expressions, since + they are nominally integer variables. LINENO is not an integer variable. + +kk. Bash temporarily suppresses the verbose option when running the DEBUG trap + while running a command from the `fc' builtin. + +ll. `wait -n' now accepts a list of job specifications as arguments and will + wait for the first one in the list to change state. + +mm. The associative array implementation can now dynamically increase the + size of the hash table based on insertion patterns. + +nn. HISTFILE is now readonly in a restricted shell. + +oo. The bash malloc now returns memory that is 16-byte aligned on 64-bit + systems. + +2. New Features in Readline + +a. If a second consecutive completion attempt produces matches where the first + did not, treat it as a new completion attempt and insert a match as + appropriate. + +b. Bracketed paste mode works in more places: incremental search strings, vi + overstrike mode, character search, and reading numeric arguments. + +c. Readline automatically switches to horizontal scrolling if the terminal has + only one line. + +d.

SHELL COMPATIBILITY MODE

+ +Bash-4.0 introduced the concept of a `shell compatibility level', specified +as a set of options to the shopt builtin +compat31, + +compat32, + +compat40, + +compat41, + +and so on). +There is only one current +compatibility level -- each option is mutually exclusive. +The compatibility level is intended to allow users to select behavior +from previous versions that is incompatible with newer versions +while they migrate scripts to use current features and +behavior. It's intended to be a temporary solution. +

+ +This section does not mention behavior that is standard for a particular +version (e.g., setting compat32 means that quoting the rhs of the regexp +matching operator quotes special regexp characters in the word, which is +default behavior in bash-3.2 and above). +

+ +If a user enables, say, compat32, it may affect the behavior of other +compatibility levels up to and including the current compatibility level. +The idea is that each compatibility level controls behavior that changed +in that version of bash, +but that behavior may have been present in earlier versions. +For instance, the change to use locale-based comparisons with the [[ +command came in bash-4.1, and earlier versions used ASCII-based comparisons, +so enabling compat32 will enable ASCII-based comparisons as well. +That granularity may not be sufficient for +all uses, and as a result users should employ compatibility levels carefully. +Read the documentation for a particular feature to find out the +current behavior. +

+ +Bash-4.3 introduced a new shell variable: +BASH_COMPAT. + + +The value assigned +to this variable (a decimal version number like 4.2, or an integer +corresponding to the compatNN option, like 42) determines the +compatibility level. +

+ +Starting with bash-4.4, Bash has begun deprecating older compatibility +levels. +Eventually, the options will be removed in favor of +BASH_COMPAT. + + +

+ +Bash-5.0 is the final version for which there will be an individual shopt +option for the previous version. Users should use +BASH_COMPAT + + +on bash-5.0 and later versions. +

+ +The following table describes the behavior changes controlled by each +compatibility level setting. +The compatNN tag is used as shorthand for setting the +compatibility level +to NN using one of the following mechanisms. +For versions prior to bash-5.0, the compatibility level may be set using +the corresponding compatNN shopt option. +For bash-4.3 and later versions, the +BASH_COMPAT + + +variable is preferred, +and it is required for bash-5.1 and later versions. +

*
+interrupting a command list such as "a ; b ; c" causes the execution +of the next command in the list (in bash-4.0 and later versions, +the shell acts as if it received the interrupt, so +interrupting one command in a list aborts the execution of the +entire list) +

*

+ + +
compat43
+ +
+
+
*
+the shell does not print a warning message if an attempt is made to +use a quoted compound assignment as an argument to declare +(declare -a foo='(1 2)'). Later versions warn that this usage is +deprecated +
*
+word expansion errors are considered non-fatal errors that cause the +current command to fail, even in posix mode +(the default behavior is to make them fatal errors that cause the shell +to exit) +
*
+when executing a shell function, the loop state (while/until/etc.) +is not reset, so break or continue in that function will break +or continue loops in the calling context. Bash-4.4 and later reset +the loop state to prevent this +
+ + +
compat44
+ +
+
+
*
+the shell sets up the values used by +BASH_ARGV + + +and +BASH_ARGC + + +so they can expand to the shell's positional parameters even if extended +debugging mode is not enabled +
*
+a subshell inherits loops from its parent context, so break +or continue will cause the subshell to exit. +Bash-5.0 and later reset the loop state to prevent the exit +
*
+variable assignments preceding builtins like export and readonly +that set attributes continue to affect variables with the same +name in the calling environment even if the shell is not in posix +mode +
+ + +
compat50
+ +
+
+
*
+Bash-5.1 changed the way +$RANDOM + + +is generated to introduce slightly +more randomness. If the shell compatibility level is set to 50 or +lower, it reverts to the method from bash-5.0 and previous versions, +so seeding the random number generator by assigning a value to +RANDOM + + +will produce the same sequence as in bash-5.0 +

      6.12 Shell Compatibility Mode

      + + + +

      Bash-4.0 introduced the concept of a ‘shell compatibility level’, specified +as a set of options to the shopt builtin +(compat31, +compat32, +compat40, +compat41, +and so on). +There is only one current +compatibility level – each option is mutually exclusive. +The compatibility level is intended to allow users to select behavior +from previous versions that is incompatible with newer versions +while they migrate scripts to use current features and +behavior. It’s intended to be a temporary solution. +

      +

      This section does not mention behavior that is standard for a particular +version (e.g., setting compat32 means that quoting the rhs of the regexp +matching operator quotes special regexp characters in the word, which is +default behavior in bash-3.2 and above). +

      +

      If a user enables, say, compat32, it may affect the behavior of other +compatibility levels up to and including the current compatibility level. +The idea is that each compatibility level controls behavior that changed +in that version of Bash, +but that behavior may have been present in earlier versions. +For instance, the change to use locale-based comparisons with the [[ +command came in bash-4.1, and earlier versions used ASCII-based comparisons, +so enabling compat32 will enable ASCII-based comparisons as well. +That granularity may not be sufficient for +all uses, and as a result users should employ compatibility levels carefully. +Read the documentation for a particular feature to find out the +current behavior. +

      +

      Bash-4.3 introduced a new shell variable: BASH_COMPAT. +The value assigned +to this variable (a decimal version number like 4.2, or an integer +corresponding to the compatNN option, like 42) determines the +compatibility level. +

      +

      Starting with bash-4.4, Bash has begun deprecating older compatibility +levels. +Eventually, the options will be removed in favor of BASH_COMPAT. +

      +

      Bash-5.0 is the final version for which there will be an individual shopt +option for the previous version. Users should use BASH_COMPAT +on bash-5.0 and later versions. +

      +

      The following table describes the behavior changes controlled by each +compatibility level setting. +The compatNN tag is used as shorthand for setting the +compatibility level +to NN using one of the following mechanisms. +For versions prior to bash-5.0, the compatibility level may be set using +the corresponding compatNN shopt option. +For bash-4.3 and later versions, the BASH_COMPAT variable is preferred, +and it is required for bash-5.1 and later versions. +

+6.12 Shell Compatibility Mode
+=============================
+
+Bash-4.0 introduced the concept of a 'shell compatibility level',
+specified as a set of options to the shopt builtin ('compat31',
+'compat32', 'compat40', 'compat41', and so on).  There is only one
+current compatibility level - each option is mutually exclusive.  The
+compatibility level is intended to allow users to select behavior from
+previous versions that is incompatible with newer versions while they
+migrate scripts to use current features and behavior.  It's intended to
+be a temporary solution.
+
+   This section does not mention behavior that is standard for a
+particular version (e.g., setting 'compat32' means that quoting the rhs
+of the regexp matching operator quotes special regexp characters in the
+word, which is default behavior in bash-3.2 and above).
+
+   If a user enables, say, 'compat32', it may affect the behavior of
+other compatibility levels up to and including the current compatibility
+level.  The idea is that each compatibility level controls behavior that
+changed in that version of Bash, but that behavior may have been present
+in earlier versions.  For instance, the change to use locale-based
+comparisons with the '[[' command came in bash-4.1, and earlier versions
+used ASCII-based comparisons, so enabling 'compat32' will enable
+ASCII-based comparisons as well.  That granularity may not be sufficient
+for all uses, and as a result users should employ compatibility levels
+carefully.  Read the documentation for a particular feature to find out
+the current behavior.
+
+   Bash-4.3 introduced a new shell variable: 'BASH_COMPAT'.  The value
+assigned to this variable (a decimal version number like 4.2, or an
+integer corresponding to the 'compat'NN option, like 42) determines the
+compatibility level.
+
+   Starting with bash-4.4, Bash has begun deprecating older
+compatibility levels.  Eventually, the options will be removed in favor
+of 'BASH_COMPAT'.
+
+   Bash-5.0 is the final version for which there will be an individual
+shopt option for the previous version.  Users should use 'BASH_COMPAT'
+on bash-5.0 and later versions.
+
+   The following table describes the behavior changes controlled by each
+compatibility level setting.  The 'compat'NN tag is used as shorthand
+for setting the compatibility level to NN using one of the following
+mechanisms.  For versions prior to bash-5.0, the compatibility level may
+be set using the corresponding 'compat'NN shopt option.  For bash-4.3
+and later versions, the 'BASH_COMPAT' variable is preferred, and it is
+required for bash-5.1 and later versions.
+
+'compat31'
+        * quoting the rhs of the '[[' command's regexp matching operator
+          (=~) has no special effect
+
+'compat32'
+        * interrupting a command list such as "a ; b ; c" causes the
+          execution of the next command in the list (in bash-4.0 and
+          later versions, the shell acts as if it received the
+          interrupt, so interrupting one command in a list aborts the
+          execution of the entire list)
+
+'compat40'
+        * the '<' and '>' operators to the '[[' command do not consider
+          the current locale when comparing strings; they use ASCII
+          ordering.  Bash versions prior to bash-4.1 use ASCII collation
+          and strcmp(3); bash-4.1 and later use the current locale's
+          collation sequence and strcoll(3).
+
+'compat41'
+        * in posix mode, 'time' may be followed by options and still be
+          recognized as a reserved word (this is POSIX interpretation
+          267)
+        * in posix mode, the parser requires that an even number of
+          single quotes occur in the WORD portion of a double-quoted
+          ${...} parameter expansion and treats them specially, so that
+          characters within the single quotes are considered quoted
+          (this is POSIX interpretation 221)
+
+'compat42'
+        * the replacement string in double-quoted pattern substitution
+          does not undergo quote removal, as it does in versions after
+          bash-4.2
+        * in posix mode, single quotes are considered special when
+          expanding the WORD portion of a double-quoted ${...} parameter
+          expansion and can be used to quote a closing brace or other
+          special character (this is part of POSIX interpretation 221);
+          in later versions, single quotes are not special within
+          double-quoted word expansions
+
+'compat43'
+        * the shell does not print a warning message if an attempt is
+          made to use a quoted compound assignment as an argument to
+          declare (declare -a foo='(1 2)').  Later versions warn that
+          this usage is deprecated
+        * word expansion errors are considered non-fatal errors that
+          cause the current command to fail, even in posix mode (the
+          default behavior is to make them fatal errors that cause the
+          shell to exit)
+        * when executing a shell function, the loop state
+          (while/until/etc.)  is not reset, so 'break' or 'continue' in
+          that function will break or continue loops in the calling
+          context.  Bash-4.4 and later reset the loop state to prevent
+          this
+
+'compat44'
+        * the shell sets up the values used by 'BASH_ARGV' and
+          'BASH_ARGC' so they can expand to the shell's positional
+          parameters even if extended debugging mode is not enabled
+        * a subshell inherits loops from its parent context, so 'break'
+          or 'continue' will cause the subshell to exit.  Bash-5.0 and
+          later reset the loop state to prevent the exit
+        * variable assignments preceding builtins like 'export' and
+          'readonly' that set attributes continue to affect variables
+          with the same name in the calling environment even if the
+          shell is not in posix mode
+
+'compat50 (set using BASH_COMPAT)'
+        * Bash-5.1 changed the way '$RANDOM' is generated to introduce
+          slightly more randomness.  If the shell compatibility level is
+          set to 50 or lower, it reverts to the method from bash-5.0 and
+          previous versions, so seeding the random number generator by
+          assigning a value to 'RANDOM' will produce the same sequence
+          as in bash-5.0

+@cindex Compatibility Level
+@cindex Compatibility Mode
+
+Bash-4.0 introduced the concept of a `shell compatibility level', specified
+as a set of options to the shopt builtin
+(@code{compat31},
+@code{compat32},
+@code{compat40},
+@code{compat41},
+and so on).
+There is only one current
+compatibility level -- each option is mutually exclusive.
+The compatibility level is intended to allow users to select behavior
+from previous versions that is incompatible with newer versions
+while they migrate scripts to use current features and
+behavior. It's intended to be a temporary solution.
+
+This section does not mention behavior that is standard for a particular
+version (e.g., setting @code{compat32} means that quoting the rhs of the regexp
+matching operator quotes special regexp characters in the word, which is
+default behavior in bash-3.2 and above). 
+
+If a user enables, say, @code{compat32}, it may affect the behavior of other
+compatibility levels up to and including the current compatibility level.
+The idea is that each compatibility level controls behavior that changed
+in that version of Bash,
+but that behavior may have been present in earlier versions.
+For instance, the change to use locale-based comparisons with the @code{[[}
+command came in bash-4.1, and earlier versions used ASCII-based comparisons,
+so enabling @code{compat32} will enable ASCII-based comparisons as well.
+That granularity may not be sufficient for
+all uses, and as a result users should employ compatibility levels carefully.
+Read the documentation for a particular feature to find out the
+current behavior.
+
+Bash-4.3 introduced a new shell variable: @env{BASH_COMPAT}.
+The value assigned
+to this variable (a decimal version number like 4.2, or an integer
+corresponding to the @code{compat}@var{NN} option, like 42) determines the
+compatibility level.
+
+Starting with bash-4.4, Bash has begun deprecating older compatibility
+levels.
+Eventually, the options will be removed in favor of @env{BASH_COMPAT}.
+
+Bash-5.0 is the final version for which there will be an individual shopt
+option for the previous version. Users should use @env{BASH_COMPAT}
+on bash-5.0 and later versions.
+
+The following table describes the behavior changes controlled by each
+compatibility level setting.
+The @code{compat}@var{NN} tag is used as shorthand for setting the
+compatibility level
+to @var{NN} using one of the following mechanisms.
+For versions prior to bash-5.0, the compatibility level may be set using
+the corresponding @code{compat}@var{NN} shopt option.
+For bash-4.3 and later versions, the @env{BASH_COMPAT} variable is preferred,
+and it is required for bash-5.1 and later versions.

 Wait until the child process specified by each process @sc{id} @var{pid}
 or job specification @var{jobspec} exits and return the exit status of the
 last command waited for.
 If a job spec is given, all processes in the job are waited for.
-If no arguments are given, all currently active child processes are
-waited for, and the return status is zero.
-If the @option{-n} option is supplied, @code{wait} waits for any job to
-terminate and returns its exit status.
-If the @option{-f} option is supplied, and job control is enabled,
-@code{wait} forces each @var{pid} or @var{jobspec} to terminate before
-returning its status, intead of returning when it changes status.
+If no arguments are given,
+@code{wait} waits for all running background jobs and
+the last-executed process substitution, if its process id is the same as
+@var{$!},
+and the return status is zero.
+If the @option{-n} option is supplied, @code{wait} waits for a single job
+from the list of @var{pids} or @var{jobspecs} or, if no arguments are
+supplied, any job, 
+to complete and returns its exit status.
+If none of the supplied arguments is a child of the shell, or if no arguments
+are supplied and the shell has no unwaited-for children, the exit status
+is 127.
+If the @option{-p} option is supplied, the process or job identifier of the job
+for which the exit status is returned is assigned to the variable
+@var{varname} named by the option argument.
+The variable will be unset initially, before any assignment.
+This is useful only when the @option{-n} option is supplied.

+forces @code{wait} to wait for each @var{pid} or @var{jobspec} to
+terminate before returning its status, intead of returning when it changes
+status.
 If neither @var{jobspec} nor @var{pid} specifies an active child process

+              the list of _i_ds or, if no _i_ds are supplied, any job, to complete

+              minate before returning its status, instead of returning when it
+              changes status.  If _i_d specifies a non-existent process or  job,
+              the  return  status is 127.  Otherwise, the return status is the

+
+SSHHEELLLL CCOOMMPPAATTIIBBIILLIITTYY MMOODDEE
+       Bash-4.0 introduced the concept of a `shell compatibility level', spec-
+       ified as a set of options to the shopt builtin ccoommppaatt3311, ccoommppaatt3322, ccoomm--
+       ppaatt4400, ccoommppaatt4411, and so on).  There is only one  current  compatibility
+       level -- each option is mutually exclusive.  The compatibility level is
+       intended to allow users to select behavior from previous versions  that
+       is  incompatible  with newer versions while they migrate scripts to use
+       current features and behavior. It's intended to be  a  temporary  solu-
+       tion.
+
+       This  section does not mention behavior that is standard for a particu-
+       lar version (e.g., setting ccoommppaatt3322 means that quoting the rhs  of  the
+       regexp  matching operator quotes special regexp characters in the word,
+       which is default behavior in bash-3.2 and above).
+
+       If a user enables, say, ccoommppaatt3322, it may affect the behavior  of  other
+       compatibility  levels  up  to  and  including the current compatibility
+       level.  The idea is that each  compatibility  level  controls  behavior
+       that  changed  in that version of bbaasshh, but that behavior may have been
+       present in earlier versions.  For instance, the change to  use  locale-
+       based  comparisons  with  the  [[[[ command came in bash-4.1, and earlier
+       versions used ASCII-based comparisons, so enabling ccoommppaatt3322 will enable
+       ASCII-based  comparisons  as  well.  That granularity may not be suffi-
+       cient for all uses, and as a result users should  employ  compatibility
+       levels  carefully.   Read the documentation for a particular feature to
+       find out the current behavior.
+
+       Bash-4.3 introduced a new shell variable: BBAASSHH__CCOOMMPPAATT.  The  value  as-
+       signed to this variable (a decimal version number like 4.2, or an inte-
+       ger corresponding to the ccoommppaatt_N_N option, like 42) determines the  com-
+       patibility level.
+
+       Starting  with bash-4.4, Bash has begun deprecating older compatibility
+       levels.  Eventually, the options will be removed in favor of  BBAASSHH__CCOOMM--
+       PPAATT.
+
+       Bash-5.0  is  the  final  version for which there will be an individual
+       shopt option for the previous version. Users should use BBAASSHH__CCOOMMPPAATT  on
+       bash-5.0 and later versions.
+
+       The  following  table describes the behavior changes controlled by each
+       compatibility level setting.  The ccoommppaatt_N_N tag is used as shorthand for
+       setting the compatibility level to _N_N using one of the following mecha-
+       nisms.  For versions prior to bash-5.0, the compatibility level may  be
+       set  using  the  corresponding ccoommppaatt_N_N shopt option.  For bash-4.3 and
+       later versions, the BBAASSHH__CCOOMMPPAATT variable is preferred, and  it  is  re-
+       quired for bash-5.1 and later versions.
+
+       ccoommppaatt3311
+              +o      quoting the rhs of the [[[[ command's regexp matching oper-
+                     ator (=~) has no special effect
+
+       ccoommppaatt3322
+              +o      interrupting a command list such as "a ; b  ;  c"  causes
+                     the  execution  of  the  next  command  in  the  list (in
+                     bash-4.0 and later versions, the shell acts as if it  re-
+                     ceived  the  interrupt,  so interrupting one command in a
+                     list aborts the execution of the entire list)
+
+       ccoommppaatt4400
+              +o      the << and >> operators to the [[[[ command do  not  consider
+                     the current locale when comparing strings; they use ASCII
+                     ordering.  Bash versions prior to bash-4.1 use ASCII col-
+                     lation  and _s_t_r_c_m_p(3); bash-4.1 and later use the current
+                     locale's collation sequence and _s_t_r_c_o_l_l(3).
+
+       ccoommppaatt4411
+              +o      in _p_o_s_i_x mode, ttiimmee may be followed by options and  still
+                     be recognized as a reserved word (this is POSIX interpre-
+                     tation 267)
+              +o      in _p_o_s_i_x mode, the parser requires that an even number of
+                     single  quotes  occur  in  the  _w_o_r_d portion of a double-
+                     quoted parameter expansion and treats them specially,  so
+                     that  characters  within the single quotes are considered
+                     quoted (this is POSIX interpretation 221)
+
+       ccoommppaatt4422
+              +o      the replacement string in double-quoted pattern substitu-
+                     tion  does  not undergo quote removal, as it does in ver-
+                     sions after bash-4.2
+              +o      in posix mode, single quotes are considered special  when
+                     expanding  the  _w_o_r_d portion of a double-quoted parameter
+                     expansion and can be used to quote  a  closing  brace  or
+                     other  special character (this is part of POSIX interpre-
+                     tation 221); in later versions,  single  quotes  are  not
+                     special within double-quoted word expansions
+
+       ccoommppaatt4433
+              +o      the  shell does not print a warning message if an attempt
+                     is made to use a quoted compound assignment as  an  argu-
+                     ment  to declare (declare -a foo='(1 2)'). Later versions
+                     warn that this usage is deprecated
+              +o      word expansion errors  are  considered  non-fatal  errors
+                     that  cause  the  current  command to fail, even in posix
+                     mode (the default behavior is to make them  fatal  errors
+                     that cause the shell to exit)
+              +o      when   executing   a   shell  function,  the  loop  state
+                     (while/until/etc.)  is not reset, so bbrreeaakk or ccoonnttiinnuuee in
+                     that function will break or continue loops in the calling
+                     context. Bash-4.4 and later reset the loop state to  pre-
+                     vent this
+
+       ccoommppaatt4444
+              +o      the  shell  sets  up  the  values  used  by BBAASSHH__AARRGGVV and
+                     BBAASSHH__AARRGGCC so they can expand to  the  shell's  positional
+                     parameters even if extended debugging mode is not enabled
+              +o      a  subshell  inherits  loops  from its parent context, so
+                     bbrreeaakk or  ccoonnttiinnuuee  will  cause  the  subshell  to  exit.
+                     Bash-5.0  and  later  reset the loop state to prevent the
+                     exit
+              +o      variable assignments preceding builtins like  eexxppoorrtt  and
+                     rreeaaddoonnllyy that set attributes continue to affect variables
+                     with the same name in the calling environment even if the
+                     shell is not in posix mode
+
+       ccoommppaatt5500
+              +o      Bash-5.1  changed  the way $$RRAANNDDOOMM is generated to intro-
+                     duce slightly more randomness. If the shell compatibility
+                     level  is  set  to  50 or lower, it reverts to the method
+                     from bash-5.0 and previous versions, so seeding the  ran-
+                     dom  number generator by assigning a value to RRAANNDDOOMM will
+                     produce the same sequence as in bash-5.0

+
+   Suppress extern inline with HP-UX cc, as it appears to be broken; see
+   .
+
+   Suppress extern inline with Sun C in standards-conformance mode, as it
+   mishandles inline functions that call each other.  E.g., for 'inline void f
+   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
+   'reference to static identifier "f" in extern inline function'.
+   This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
+
+   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
+   on configurations that mistakenly use 'static inline' to implement
+   functions or macros in standard C headers like .  For example,
+   if isdigit is mistakenly implemented via a static inline function,
+   a program containing an extern inline function that calls isdigit
+   may not work since the C standard prohibits extern inline functions
+   from calling static functions (ISO C 99 section 6.7.4.(3).
+   This bug is known to occur on:
+
+     OS X 10.8 and earlier; see:
+     https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
+
+     DragonFly; see
+     http://muscles.dragonflybsd.org/bulk/bleeding-edge-potential/latest-per-pkg/ah-tty-0.3.12.log
+
+     FreeBSD; see:
+     https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
+
+   OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
+   for clang but remains for g++; see .
+   Assume DragonFly and FreeBSD will be similar.
+
+   GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+   inline semantics, unless -fgnu89-inline is used.  It defines a macro
+   __GNUC_STDC_INLINE__ to indicate this situation or a macro
+   __GNUC_GNU_INLINE__ to indicate the opposite situation.
+   GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
+   semantics but warns, unless -fgnu89-inline is used:
+     warning: C99 inline functions are not supported; using GNU89
+     warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
+   It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl    default (if it is not specified or empty) is 'no-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99  formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value '$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+
+dnl Sets the HOST_CPU variable to the canonical name of the CPU.
+dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
+dnl C language ABI (application binary interface).
+dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
+dnl config.h.
+dnl
+dnl This canonical name can be used to select a particular assembly language
+dnl source file that will interoperate with C code on the given host.
+dnl
+dnl For example:
+dnl * 'i386' and 'sparc' are different canonical names, because code for i386
+dnl   will not run on SPARC CPUs and vice versa. They have different
+dnl   instruction sets.
+dnl * 'sparc' and 'sparc64' are different canonical names, because code for
+dnl   'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
+dnl   contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
+dnl   instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
+dnl   mode, but not both.
+dnl * 'mips' and 'mipsn32' are different canonical names, because they use
+dnl   different argument passing and return conventions for C functions, and
+dnl   although the instruction set of 'mips' is a large subset of the
+dnl   instruction set of 'mipsn32'.
+dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
+dnl   different sizes for the C types like 'int' and 'void *', and although
+dnl   the instruction sets of 'mipsn32' and 'mips64' are the same.
+dnl * The same canonical name is used for different endiannesses. You can
+dnl   determine the endianness through preprocessor symbols:
+dnl   - 'arm': test __ARMEL__.
+dnl   - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
+dnl   - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN.
+dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
+dnl   (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
+dnl   - Instructions that do not exist on all of these CPUs (cmpxchg,
+dnl     MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
+dnl     assembly language source files use such instructions, you will
+dnl     need to make the distinction.
+dnl   - Speed of execution of the common instruction set is reasonable across
+dnl     the entire family of CPUs. If you have assembly language source files
+dnl     that are optimized for particular CPU types (like GNU gmp has), you
+dnl     will need to make the distinction.

+dnl Inspired by
+dnl https://github.com/linux-test-project/ltp/blob/master/testcases/open_posix_testsuite/conformance/interfaces/pthread_rwlock_rdlock/2-2.c
+dnl by Intel Corporation.
+
+dnl Test whether in a situation where
+dnl   - an rwlock is taken by a reader and has a writer waiting,
+dnl   - an additional reader requests the lock,
+dnl   - the waiting writer and the requesting reader threads have the same
+dnl     priority,
+dnl the requesting reader thread gets blocked, so that at some point the
+dnl waiting writer can acquire the lock.
+dnl Without such a guarantee, when there a N readers and each of the readers
+dnl spends more than 1/Nth of the time with the lock held, there is a high
+dnl probability that the waiting writer will not get the lock in a given finite
+dnl time, a phenomenon called "writer starvation".
+dnl Without such a guarantee, applications have a hard time avoiding writer
+dnl starvation.
+dnl
+dnl POSIX:2017 makes this requirement only for implementations that support TPS
+dnl (Thread Priority Scheduling) and only for the scheduling policies SCHED_FIFO
+dnl and SCHED_RR, see
+dnl http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_rwlock_rdlock.html
+dnl but this test verifies the guarantee regardless of TPS and regardless of
+dnl scheduling policy.
