Merge branch 'release/5.8.2'

{html_image} already escaped alt and pass-through attributes, but emitted
file, path_prefix, href/link, width and height raw, letting an untrusted
value break out of the generated tag. Escape these at output time; the
unescaped values are still used for getimagesize()/DPI math. Escaping uses
htmlspecialchars with double_encode=false, so existing entities and values
like "100%" are preserved (no BC break for legitimate values).

{html_select_date} treated day_size/month_size/year_size as strings and
emitted them raw into size="…"; cast them to int to match
{html_select_time} and close the breakout.

The remaining flagged parameters (mailto extra; html_table *_attr/
trailpad/caption/loop; html_radios/html_checkboxes separator;
html_select_* *_extra/field_separator and the unrecognised-attribute
pass-through) intentionally emit raw markup as documented, so escaping
them would break backwards compatibility. Add a security note to those
docs pages instead, telling authors to escape untrusted values themselves.

Adds tests for html_image escaping (incl. benign-value/no-double-encode
checks) and the html_select_date size cast.

+# AGENTS.md
+
+This file is the single source of truth for AI coding assistants working in this repo (including Claude Code, claude.ai/code).
+
+## Project
+
+Smarty v5 — PHP template engine. Single Composer package (`smarty/smarty`), namespace `Smarty\`, source in `src/`, autoloaded via PSR-4. Supports PHP 7.2–8.5.
+
+Do not use PHP syntax newer than 7.2 in `src/` unless it is guarded for older runtimes.
+
+## Commands
+
+```bash
+# Install dependencies
+composer install
+
+# Regenerate lexers and parsers (required before tests; CI runs this)
+make -B
+
+# Run all tests
+php ./vendor/phpunit/phpunit/phpunit
+
+# Run a single test file
+php ./vendor/phpunit/phpunit/phpunit tests/UnitTests/TemplateSource/TagTests/If/CompileIfTest.php
+
+# Run tests matching a PHPUnit group
+php ./vendor/phpunit/phpunit/phpunit --group 20221124
+
+# Run tests excluding slow group
+php ./vendor/phpunit/phpunit/phpunit --exclude-group slow
+```
+
+There is no linter or static analysis configured. No typecheck step.
+
+## Generated code — do not hand-edit
+
+Four files are generated from grammar/lexer definitions via `make`:
+
+| Source (edit this) | Generated (do not edit) |
+|---|---|
+| `src/Lexer/TemplateLexer.plex` | `src/Lexer/TemplateLexer.php` |
+| `src/Lexer/ConfigfileLexer.plex` | `src/Lexer/ConfigfileLexer.php` |
+| `src/Parser/TemplateParser.y` | `src/Parser/TemplateParser.php` |
+| `src/Parser/ConfigfileParser.y` | `src/Parser/ConfigfileParser.php` |
+
+After editing a `.plex` or `.y` file, run `make -B` to regenerate. The generators require the `smarty/smarty-lexer` dev dependency.
+
+## Architecture
+
+- `src/Smarty.php` — main class, extends `TemplateBase`. Version constant: `Smarty::SMARTY_VERSION`.
+- `src/Compile/`, `src/Compiler/` — template compilation pipeline.
+- `src/Lexer/`, `src/Parser/` — lexer/parser (generated, see above).
+- `src/Extension/` — extension system (`ExtensionInterface`, `CoreExtension`, `DefaultExtension`, `BCPluginsAdapter`).
+- `src/Runtime/` — runtime helpers (foreach, capture, inheritance, tpl functions).
+- `src/Resource/`, `src/Cacheresource/` — template resource and cache resource handlers.
+- `src/BlockHandler/`, `src/FunctionHandler/`, `src/Filter/` — built-in tags, functions, and filters.
+- `libs/Smarty.class.php` — non-Composer autoload stub. Points to `src/`. Not the main source.
+- `src/functions.php` — global helper functions, always loaded via Composer `files` autoload.
+
+## Tests
+
+- Framework: PHPUnit 7.5/8.5 (bootstrap: `tests/Bootstrap.php`).
+- All tests extend `PHPUnit_Smarty` (defined in `tests/PHPUnit_Smarty.php`), which provides `setUpSmarty($dir)`.
+- Test suite root: `tests/UnitTests/`. Typical test `setUp()` calls `$this->setUpSmarty(__DIR__)`.
+- Each test directory may have its own `templates/`, `configs/` subdirectories. Compiled output goes to `templates_c/` and `cache/` (auto-created by the test harness).
+- Running the suite scatters generated `templates_c/`, `cache/`, and `templates_tmp/` directories (and empty runtime `templates/`/`configs/` dirs) throughout `tests/` and the repo root. These are not tracked — treat them as noise in `git status`, never commit them, and clean them with `git clean -fd` (exclude tool dirs like `.serena`).
+- Three test files are excluded in `phpunit.xml`: Memcache, APC, and HttpModifiedSince tests (require external services).
+- Tests needing MySQL/PDO are gated by constants in `tests/Config.php` (disabled by default).
+
+## CI
+
+GitHub Actions (`.github/workflows/ci.yml`): matrix of PHP 7.2–8.5 on ubuntu + windows. Steps: `composer install` → `make -B` → `phpunit`. No deploy step.
+
+## Docs
+
+Markdown in `docs/`, built with mkdocs + Material theme. Preview: `mkdocs serve`. Published via `mike deploy 5.x`.
+
+## Release
+
+`./make-release.sh <version>` — only v5.x.x. Updates changelog and version constant, creates a merge commit and tag on `master`.
+
+### Changelog
+
+Every change that should appear in `CHANGELOG.md` must add a new markdown file under `changelog/`. At release time `utilities/update-changelog.php` concatenates all `changelog/*.md` files into the `## [Unreleased]` section, so:
+
+- One file per change, containing a single line that starts with a dash (`- ...`). The filename is arbitrary; name it after the issue number (e.g. `1036.md`) when there is one, otherwise use a short descriptive slug.
+- Include a markdown link to the relevant issue when one exists, e.g. `[#1036](https://github.com/smarty-php/smarty/issues/1036)`. Omit the link when there is no public issue (e.g. embargoed security reports).

+- Security: prevent symlinks inside a trusted `secure_dir`/template directory from being used to read files outside of it (CWE-22 path traversal), affecting `{include}` and `{fetch}` of local files
+- Security: `{html_image}` now escapes the `file`, `path_prefix`, `href`/`link`, `width` and `height` attributes (it already escaped `alt` and pass-through attributes), and `{html_select_date}` casts `day_size`/`month_size`/`year_size` to int (matching `{html_select_time}`), preventing untrusted values passed into these attributes from breaking out of the generated HTML (CWE-79)
+- Security: `{fetch}` no longer follows HTTP redirects for remote resources while a security policy is active, preventing an open redirect on a trusted host from bypassing `trusted_uri` (CWE-918 server-side request forgery)

+## Regex Matching Operator
+
+The `matches` operator allows you to test if a string matches a regular expression pattern.
+
+### Basic Usage
+
+```smarty
+{if "hello" matches "/^[a-z]+$/"}
+    String matches the pattern!
+{/if}
+
+{if $email matches "/^[^@]+@[^@]+\.[^@]+$/"}
+    Valid email format
+{else}
+    Invalid email format
+{/if}
+```
+
+### Using Variables
+
+```smarty
+{$pattern = '/^[a-zA-Z0-9]{8,}$/'}
+{if $password matches $pattern}
+    Password meets requirements
+{else}
+    Password must be at least 8 alphanumeric characters
+{/if}
+```
+
+### Pattern Modifiers
+
+The `matches` operator supports all standard PHP regex modifiers:
+
+```smarty
+{* Case insensitive matching *}
+{if "HELLO" matches "/hello/i"}
+    Matches (case insensitive)
+{/if}
+
+{* Multiline mode *}
+{if "line1\nline2" matches "/line2$/m"}
+    Matches in multiline mode
+{/if}
+
+{* Dot matches newlines *}
+{if "hello\nworld" matches "/hello.world/s"}
+    Matches with dotall modifier
+{/if}
+```
+
+### Complex Conditions
+
+The `matches` operator can be combined with other operators:
+
+```smarty
+{if $username matches "/^[a-z]+$/" && $username|length > 3}
+    Valid username
+{else}
+    Username must be lowercase letters and at least 4 characters
+{/if}
+
+{if $input matches "/^[0-9]+$/" || $input matches "/^[a-z]+$/"}
+    Input is either numeric or lowercase letters
+{else}
+    Invalid input format
+{/if}
+```
+
+### Practical Examples
+
+**Email Validation:**
+```smarty
+{if $email matches "/^[^@\s]+@[^@\s]+\.[^@\s]+$/"}
+    Valid email address
+{else}
+    Please enter a valid email address
+{/if}
+```
+
+**Password Strength:**
+```smarty
+{if $password matches "/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d).{8,}$/"}
+    Strong password
+{else}
+    Password must contain uppercase, lowercase, numbers and be at least 8 characters
+{/if}
+```
+
+**URL Validation:**
+```smarty
+{if $url matches "/^https?:\/\/(www\.)?[a-z0-9\-]+(\.[a-z]{2,})+/i"}
+    Valid URL format
+{else}
+    Please enter a valid URL
+{/if}
+```
+
+**Numeric Validation:**
+```smarty
+{if $input matches "/^[0-9]+$/"}
+    Valid numeric input
+{else}
+    Please enter numbers only
+{/if}
+```
+
+### Notes
+
+- The `matches` operator uses PHP's `preg_match()` function internally
+- Pattern delimiters must be valid regex delimiters (typically `/`)
+- Invalid patterns will cause PHP warnings but won't break template execution
+- For complex regex patterns, consider using variables for better readability
+
 ## Ternary
 You can use the `?:` (or ternary) operator to test one expression and present the value
 of the second or third expression, based on the result of the test.

+## Backed Enums (PHP 8.1+)
+
+Smarty supports accessing properties of [backed enums](https://www.php.net/manual/en/language.enumerations.backed.php) introduced in PHP 8.1.
+
+### Accessing Enum Properties
+
+You can access the `name` and `value` properties of backed enum cases:
+
+```smarty
+{* Access enum case properties *}
+<option id="{MyEnum::Foo->name}">{MyEnum::Foo->value}</option>
+```
+
+### Complete Example
+
+```php
+<?php
+use Smarty\Smarty;
+
+// Define a backed enum
+enum Status: string {
+    case Active = 'active';
+    case Inactive = 'inactive';
+    case Pending = 'pending';
+}
+
+$smarty = new Smarty();
+$smarty->assign('currentStatus', Status::Active);
+$smarty->display('template.tpl');
+```
+
+`template.tpl`:
+
+```smarty
+{* Display enum properties *}
+Current status: {$currentStatus->name} (value: {$currentStatus->value})
+
+{* Use in HTML attributes *}
+<select name="status">
+    <option value="{Status::Active->value}" {if $currentStatus->name === 'Active'}selected{/if}>Active</option>
+    <option value="{Status::Inactive->value}" {if $currentStatus->name === 'Inactive'}selected{/if}>Inactive</option>
+    <option value="{Status::Pending->value}" {if $currentStatus->name === 'Pending'}selected{/if}>Pending</option>
+</select>
+```
+
+This would output:
+
+```html
+Current status: Active (value: active)
+
+<select name="status">
+    <option value="active" selected>Active</option>
+    <option value="inactive">Inactive</option>
+    <option value="pending">Pending</option>
+</select>
+```
+
+### Integer-backed Enums
+
+Integer-backed enums work the same way:
+
+```php
+<?php
+enum Priority: int {
+    case Low = 1;
+    case Medium = 2; 
+    case High = 3;
+}
+
+$smarty->assign('priority', Priority::High);
+```
+
+```smarty
+{* Access integer enum properties *}
+Priority level: {$priority->value} ({$priority->name})
+```
+
+Output:
+
+```html
+Priority level: 3 (High)
+```
+
+> **Note**: Backed enum support requires PHP 8.1 or higher. The enum must be registered or available in the current namespace.

+
+Smarty v4 allowed setting (internal) properties for which no setter existed by using magic methods 
+that start with either `set` or `get`. This has been removed in Smarty 5.

+For example, `$smarty->setErrorUnassigned(true);` would set the `error_unassigned` property.
