This replaces the AC_MSG_ERROR with AC_MSG_FAILURE, where appropriate. The AC_MSG_ERROR outputs given message and exits the configure step. The AC_MSG_FAILURE does the same but also automatically outputs additional message "See 'config.log' for more details." which might help directing the user where to look further. The AC_MSG_ERROR is used for errors where current test step isn't logged in the config.log and wouldn't make sense, and AC_MSG_FAILURE is mostly used in cases of library checks, compilation tests, headers checked with AC_CHECK_HEADER* and similar tests that are also logged in the config.log. AC_MSG_ERROR([Sanity check failed.]) output: ``` configure: error: Sanity check failed. ``` AC_MSG_FAILURE([Sanity check failed.]) output: ``` configure: error: in '/path/to/php-src': configure: error: Sanity check failed. See 'config.log' for more details ``` |

readline
Provides generic line editing, history, and tokenization functions. See https://www.php.net/manual/en/book.readline.php
Implementation Details
C variables starting with rl_*
are declared by the readline library
(or are macros referring to variables from the libedit library).
See http://web.mit.edu/gnu/doc/html/rlman_2.html
This should only be used in the CLI SAPI. Historically, the code lived in sapi/cli, but many distributions build readline as a shared extension. Therefore, that code was split into ext/readline so that this can dynamically be loaded. With other SAPIs, readline is/should be disabled.
readline_cli.c
implements most of the interactive shell(php -a
).
