+## What is this repository about?
 
 This repository contains most of the resources that you would need to build
 Copacabana, in case a build consolidation made of small scripts that
 automate the process.  
+This time, we're trying a build using LLVM and following a considerable part of
+dslm4515's [Clang Musl Linux from Scratch](https://github.com/dslm4515/CMLFS.git)
+guide for building the toolchain. We aim to both get Copacabana fully built wit
+LLVM and to cooperate with CMLFS, sending patches when help needed and/or flaws
+discovered in the process.  
+If it succeeds and presents a nice performance, this branch will be merged into
+the main branch.
 
 For more information about porting, translation, documentation etc, read
 the website: http://copacabana.pindorama.dob.jp

+;;;;;;;;;;
+; About php.ini   ;
+;;;;;;;;;;
+; PHP's initialization file, generally called php.ini, is responsible for
+; configuring many of the aspects of PHP's behavior.
+
+; PHP attempts to find and load this configuration from a number of locations.
+; The following is a summary of its search order:
+; 1. SAPI module specific location.
+; 2. The PHPRC environment variable. (As of PHP 5.2.0)
+; 3. A number of predefined registry keys on Windows (As of PHP 5.2.0)
+; 4. Current working directory (except CLI)
+; 5. The web server's directory (for SAPI modules), or directory of PHP
+; (otherwise in Windows)
+; 6. The directory from the --with-config-file-path compile time option, or the
+; Windows directory (C:\windows or C:\winnt)
+; See the PHP docs for more specific information.
+; http://php.net/configuration.file
+
+; The syntax of the file is extremely simple.  Whitespace and lines
+; beginning with a semicolon are silently ignored (as you probably guessed).
+; Section headers (e.g. [Foo]) are also silently ignored, even though
+; they might mean something in the future.
+
+; Directives following the section heading [PATH=/www/mysite] only
+; apply to PHP files in the /www/mysite directory.  Directives
+; following the section heading [HOST=www.example.com] only apply to
+; PHP files served from www.example.com.  Directives set in these
+; special sections cannot be overridden by user-defined INI files or
+; at runtime. Currently, [PATH=] and [HOST=] sections only work under
+; CGI/FastCGI.
+; http://php.net/ini.sections
+
+; Directives are specified using the following syntax:
+; directive = value
+; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
+; Directives are variables used to configure PHP or PHP extensions.
+; There is no name validation.  If PHP can't find an expected
+; directive because it is not set or is mistyped, a default value will be used.
+
+; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
+; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
+; (e.g. E_ALL & ~E_NOTICE), a quoted string ("bar"), or a reference to a
+; previously set variable or directive (e.g. ${foo})
+
+; Expressions in the INI file are limited to bitwise operators and parentheses:
+; |  bitwise OR
+; ^  bitwise XOR
+; &  bitwise AND
+; ~  bitwise NOT
+; !  boolean NOT
+
+; Boolean flags can be turned on using the values 1, On, True or Yes.
+; They can be turned off using the values 0, Off, False or No.
+
+; An empty string can be denoted by simply not writing anything after the equal
+; sign, or by using the None keyword:
+
+;  foo =         ; sets foo to an empty string
+;  foo = None    ; sets foo to an empty string
+;  foo = "None"  ; sets foo to the string 'None'
+
+; If you use constants in your value, and these constants belong to a
+; dynamically loaded extension (either a PHP extension or a Zend extension),
+; you may only use these constants *after* the line that loads the extension.
+
+;;;;;;;;;;
+; About this file ;
+;;;;;;;;;;
+; PHP comes packaged with two INI files. One that is recommended to be used
+; in production environments and one that is recommended to be used in
+; development environments.
+
+; php.ini-production contains settings which hold security, performance and
+; best practices at its core. But please be aware, these settings may break
+; compatibility with older or less security conscience applications. We
+; recommending using the production ini in production and testing environments.
+
+; php.ini-development is very similar to its production variant, except it is
+; much more verbose when it comes to errors. We recommend using the
+; development version only in development environments, as errors shown to
+; application users can inadvertently leak otherwise secure information.
+
+; This is php.ini-production INI file.
+
+;;;;;;;;;;
+; Quick Reference ;
+;;;;;;;;;;
+; The following are all the settings which are different in either the production
+; or development versions of the INIs with respect to PHP's default behavior.
+; Please see the actual settings later in the document for more details as to why
+; we recommend these changes in PHP's behavior.

+
+; This directive determines whether or not PHP will recognize code between
+; <? and ?> tags as PHP source which should be processed as such. It is
+; generally recommended that <?php and ?> should be used and that this feature
+; should be disabled, as enabling it may result in issues when generating XML
+; documents, however this remains supported for backward compatibility reasons.
+; Note that this directive does not control the <?= shorthand tag, which can be
+; used regardless of this directive.

+
+; Output buffering is a mechanism for controlling how much output data
+; (excluding headers and cookies) PHP should keep internally before pushing that
+; data to the client. If your application's output exceeds this setting, PHP
+; will send that data in chunks of roughly the size you specify.
+; Turning on this setting and managing its maximum buffer size can yield some
+; interesting side-effects depending on your application and web server.
+; You may be able to send headers and cookies after you've already sent output
+; through print or echo. You also may see performance benefits if your server is
+; emitting less packets due to buffered output versus PHP streaming the output
+; as it gets it. On production servers, 4096 bytes is a good setting for performance
+; reasons.
+; Note: Output buffering can also be controlled via Output Buffering Control
+;   functions.
+; Possible Values:
+;   On = Enabled and buffer is unlimited. (Use with caution)
+;   Off = Disabled
+;   Integer = Enables the buffer and sets its maximum size in bytes.
+; Note: This directive is hardcoded to Off for the CLI SAPI
+; Default Value: Off
+; Development Value: 4096
+; Production Value: 4096
+; http://php.net/output-buffering
+output_buffering = 4096
+
+; You can redirect all of the output of your scripts to a function.  For
+; example, if you set output_handler to "mb_output_handler", character
+; encoding will be transparently converted to the specified encoding.
+; Setting any output handler automatically turns on output buffering.
+; Note: People who wrote portable scripts should not depend on this ini
+;   directive. Instead, explicitly set the output handler using ob_start().
+;   Using this ini directive may cause problems unless you know what script
+;   is doing.
+; Note: You cannot use both "mb_output_handler" with "ob_iconv_handler"
+;   and you cannot use both "ob_gzhandler" and "zlib.output_compression".
+; Note: output_handler must be empty if this is set 'On' !!!!
+;   Instead you must use zlib.output_handler.
+; http://php.net/output-handler

+
+; URL rewriter function rewrites URL on the fly by using
+; output buffer. You can set target tags by this configuration.
+; "form" tag is special tag. It will add hidden input tag to pass values.
+; Refer to session.trans_sid_tags for usage.
+; Default Value: "form="
+; Development Value: "form="
+; Production Value: "form="
+url_rewriter.tags
+
+; URL rewriter will not rewrites absolute URL nor form by default. To enable
+; absolute URL rewrite, allowed hosts must be defined at RUNTIME.
+; Refer to session.trans_sid_hosts for more details.
+; Default Value: ""
+; Development Value: ""
+; Production Value: ""
+url_rewriter.hosts
+
+; Transparent output compression using the zlib library
+; Valid values for this option are 'off', 'on', or a specific buffer size
+; to be used for compression (default is 4KB)
+; Note: Resulting chunk size may vary due to nature of compression. PHP
+;   outputs chunks that are few hundreds bytes each as a result of
+;   compression. If you prefer a larger chunk size for better
+;   performance, enable output_buffering in addition.
+; Note: You need to use zlib.output_handler instead of the standard
+;   output_handler, or otherwise the output will be corrupted.
+; http://php.net/zlib.output-compression
+zlib.output_compression = Off
+
+; http://php.net/zlib.output-compression-level
+zlib.output_compression_level = -1
+
+; You cannot specify additional output handlers if zlib.output_compression
+; is activated here. This setting does the same as output_handler but in
+; a different order.
+; http://php.net/zlib.output-handler
+zlib.output_handler =
+
+; Implicit flush tells PHP to tell the output layer to flush itself
+; automatically after every output block.  This is equivalent to calling the
+; PHP function flush() after each and every call to print() or echo() and each
+; and every HTML block.  Turning this option on has serious performance
+; implications and is generally recommended for debugging purposes only.
+; http://php.net/implicit-flush

+; So only set this entry, if you really want to implement such a
+; callback-function.
+unserialize_callback_func =
+
+; When floats & doubles are serialized, store serialize_precision significant
+; digits after the floating point. The default value ensures that when floats
+; are decoded with unserialize, the data will remain the same.
+; The value is also used for json_encode when encoding double values.
+; If -1 is used, then dtoa mode 0 is used which automatically select the best
+; precision.
+serialize_precision = -1
+
+; open_basedir, if set, limits all file operations to the defined directory

+; Error handling and logging ;
+;;;;;;;;;;;;;;;
+
+; This directive informs PHP of which errors, warnings and notices you would like
+; it to take action for. The recommended way of setting values for this
+; directive is through the use of the error level constants and bitwise
+; operators. The error level constants are below here for convenience as well as
+; some common settings and their meanings.
+; By default, PHP is set to take action on all errors, notices and warnings EXCEPT
+; those related to E_NOTICE and E_STRICT, which together cover best practices and
+; recommended coding standards in PHP. For performance reasons, this is the
+; recommend error reporting setting. Your production server shouldn't be wasting
+; resources complaining about best practices and coding standards. That's what
+; development servers and development settings are for.
+; Note: The php.ini-development file has this setting as E_ALL. This
+; means it pretty much reports everything which is exactly what you want during
+; development and early testing.
+;
+; Error Level Constants:
+; E_ALL             - All errors and warnings (includes E_STRICT as of PHP 5.4.0)
+; E_ERROR           - fatal run-time errors
+; E_RECOVERABLE_ERROR  - almost fatal run-time errors
+; E_WARNING         - run-time warnings (non-fatal errors)
+; E_PARSE           - compile-time parse errors
+; E_NOTICE          - run-time notices (these are warnings which often result
+;                     from a bug in your code, but it's possible that it was
+;                     intentional (e.g., using an uninitialized variable and
+;                     relying on the fact it is automatically initialized to an
+;                     empty string)
+; E_STRICT          - run-time notices, enable to have PHP suggest changes
+;                     to your code which will ensure the best interoperability
+;                     and forward compatibility of your code
+; E_CORE_ERROR      - fatal errors that occur during PHP's initial startup
+; E_CORE_WARNING    - warnings (non-fatal errors) that occur during PHP's
+;                     initial startup
+; E_COMPILE_ERROR   - fatal compile-time errors
+; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
+; E_USER_ERROR      - user-generated error message
+; E_USER_WARNING    - user-generated warning message
+; E_USER_NOTICE     - user-generated notice message
+; E_DEPRECATED      - warn about code that will not work in future versions
+;                     of PHP
+; E_USER_DEPRECATED - user-generated deprecation warnings
+;
+; Common Values:
+;   E_ALL (Show all errors, warnings and notices including coding standards.)
+;   E_ALL & ~E_NOTICE  (Show all errors, except for notices)
+;   E_ALL & ~E_NOTICE & ~E_STRICT  (Show all errors, except for notices and coding standards warnings.)
+;   E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR  (Show only errors)
+; Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
+; Development Value: E_ALL
+; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT
+; http://php.net/error-reporting
+error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
+
+; This directive controls whether or not and where PHP will output errors,
+; notices and warnings too. Error output is very useful during development, but
+; it could be very dangerous in production environments. Depending on the code
+; which is triggering the error, sensitive information could potentially leak
+; out of your application such as database usernames and passwords or worse.
+; For production environments, we recommend logging errors rather than
+; sending them to STDOUT.
+; Possible Values:
+;   Off = Do not display any errors
+;   stderr = Display errors to STDERR (affects only CGI/CLI binaries!)
+;   On or stdout = Display errors to STDOUT
+; Default Value: On
+; Development Value: On
+; Production Value: Off
+; http://php.net/display-errors
+display_errors = Off
+
+; The display of errors which occur during PHP's startup sequence are handled
+; separately from display_errors. PHP's default behavior is to suppress those
+; errors from clients. Turning the display of startup errors on can be useful in
+; debugging configuration problems. We strongly recommend you
+; set this to 'off' for production servers.
+; Default Value: Off
+; Development Value: On
+; Production Value: Off
+; http://php.net/display-startup-errors
+display_startup_errors = Off
+
+; Besides displaying errors, PHP can also log errors to locations such as a
+; server-specific log, STDERR, or a location specified by the error_log
+; directive found below. While errors should not be displayed on productions
+; servers they should still be monitored and logging is a great way to do that.
+; Default Value: Off
+; Development Value: On
+; Production Value: On
+; http://php.net/log-errors
+log_errors = On
+
+; Set maximum length of log_errors. In error_log information about the source is
+; added. The default is 1024 and 0 allows to not apply any maximum length at all.
+; http://php.net/log-errors-max-len
+log_errors_max_len = 1024
+
+; Do not log repeated messages. Repeated errors must occur in same file on same
+; line unless ignore_repeated_source is set true.
+; http://php.net/ignore-repeated-errors
+ignore_repeated_errors = Off
+
+; Ignore source of message when ignoring repeated messages. When this setting
+; is On you will not log errors with repeated messages from different files or
+; source lines.
+; http://php.net/ignore-repeated-source
+ignore_repeated_source = Off
+
+; If this parameter is set to Off, then memory leaks will not be shown (on
+; stdout or in the log). This has only effect in a debug compile, and if
+; error reporting includes E_WARNING in the allowed list
+; http://php.net/report-memleaks
+report_memleaks = On
+
+; This setting is on by default.
+report_zend_debug = 0
+
+; Store the last error/warning message in $php_errormsg (boolean). Setting this value
+; to On can assist in debugging and is appropriate for development servers. It should
+; however be disabled on production servers.

+xmlrpc_error_number = 0
+
+; When PHP displays or logs an error, it has the capability of formatting the
+; error message as HTML for easier reading. This directive controls whether
+; the error message is formatted as HTML or not.
+; Note: This directive is hardcoded to Off for the CLI SAPI
+; Default Value: On
+; Development Value: On
+; Production value: On
+; http://php.net/html-errors
+html_errors = On
+
+; If html_errors is set to On *and* docref_root is not empty, then PHP

+; or function causing the error in detail.
+; You can download a copy of the PHP manual from http://php.net/docs
+; and change docref_root to the base URL of your local copy including the
+; leading '/'. You must also specify the file extension being used including
+; the dot. PHP's default behavior is to leave these settings empty, in which

+; Argument passed to save_handler.  In the case of files, this is the path
+; where data files are stored. Note: Windows users have to change this
+; variable in order to use PHP's session functions.
+;
+; The path can be defined as:
+;
+;     session.save_path = "N/path"
+;
+; where N is an integer.  Instead of storing all the session files in
+; /path, what this will do is use subdirectories N-levels deep, and
+; store the session data in those directories.  This is useful if
+; your OS has problems with many files in one directory, and is
+; a more efficient layout for servers that handle many sessions.
+;
+; NOTE 1: PHP will not create this directory structure automatically.
+;         You can use the script in the ext/session dir for that purpose.
+; NOTE 2: See the section on garbage collection below if you choose to
+;         use subdirectories for session storage
+;
+; The file storage module creates files using mode 600 by default.
+; You can change that by using
+;
+;     session.save_path = "NMODE/path"
+;
+; where MODE is the octal representation of the mode. Note that this

Subject: [PATCH 042/128] docs: Bump Heirloom NG to 20240220-fix until it gets
 merged into master and/or a new release is made.

This branch improves seq(1) with a safer and more complete (UNIX v8 payloads with extensions) implementation and also implements timeout(1).

Subject: [PATCH 043/128] chore: Fix built-in timeout() function for handling
 parameters with space and also made it aware of a installed timeout(1)
 implementation.

The latter was done because Heirloom NG got an timeout(1) implementation at 20240220.

 the physical disk.

Just a note out of curiosity: `[[ "$(file "$disk_block")" =~ (.*[\t ]block special.*) ]]' works for both Heirloom Toolchest/NG's implementation of file(1) and Ian Darwin's, since it can catch both a tab or a single space.

Subject: [PATCH 053/128] fix: Do not call defined() in subshells because it
 causes an error in ksh93 1.0.0-beta.

Simply put, when one tries to run a function/command in a subshell that does not print nothing, it will try to execute `1>' instead of just continuing with the return code being returned. That payload was removed in latest versions for some reason.

Subject: [PATCH 089/128] feat!: Use new log() function based on @xplshn's
 work.

With a little bit of code copi... I mean, inspiration from herbiec's printlog(), (ab)using some KornShell 93/GNU Bash features and using the "I_ENJOY_THAT_THINGS_ARE_REALLY_CLEAR" preference from machine.ini; also with rigorous checks for colour support in the terminal being used and a more pfmt(3C)-esque approach instead of the '--flag' one, besides some inspiration also drawn from Google Go's stdlib log package.

This was suggested at https://github.com/Projeto-Pindorama/copacabana/issues/8#issuecomment-2263609139

Not necessarily related to this commit, but, if you please, take a listen to Astrud Gilberto's cover of a Jorge Ben song: https://youtu.be/EWv4mLbh8xo
