- PATH_LIB_BRIDGES defines the path to bridges
- PATH_LIB_FORMATS defines the path to formats
- PATH_LIB_CACHES defines the path to caches
Include constants in RssBridge.php for consistency
Move CACHE_DIR from index.php to /lib/RssBridge.php and change name
to PATH_CACHE.
PATH_CACHE is one of the core paths of RSS-Bridge and should therefore
be defined in the core file RssBridge.php.
- Remove file documentation and license remark (defined in repository
scope - see README / UNLICENSE)
- Remove example usage (if necessary should be included in the Wiki)
"The require_once statement is identical to require except PHP will
check if the file has already been included, and if so, not include
(require) it again."
-- http://php.net/manual/en/function.require-once.php
Vendor files (simple_html_dom.php and urljoin.php) are included in the
repository and therefore shipped with all releases. If one of the files
is missing, either the repository or the release is incomplete.
PHP will generate error messages if either of the files is missing, so
there is no need to check availability manually unless it is done for
all files (which doesn't make sense because they are part of the
repository).
Adds additional messages to the error log when fetching contents. The
data is helpful in finding issues with receiving contents from servers.

* [BridgeAbstract] Rename 'getCacheTime' to 'getModifiedTime'
* [BridgeAbstract] Move caching to index.php to separate concerns
index.php needs more control over caching behavior in order to cache
exceptions. This cannot be done in a bridge, as the bridge might be
broken, thus preventing caching from working.
This also (and more importantly) separates concerns. The bridge should
not even care if caching is involved or not. Its purpose is to collect
and provide data.
Response times should be faster, as more complex bridge functions like
'setDatas' (evaluates all input parameters to predict the current
context) and 'collectData' (collects data from sites) can be skipped
entirely.
Notice: In its current form, index.php takes care of caching. This
could, however, be moved into a separate class (i.e. CacheAbstract)
in order to make implementation details cache specific.
* [index] Add '_error_time' parameter to $item['uri']
This ensures that error messages are recognized by feed readers as
new errors after 24 hours. During that time the same item is returned
no matter how often the cache is cleared.

* [index] Include '_error_time' in the title for errors
This prevents feed readers from "updating" feeds based on the title
* [index] Handle "HTTP_IF_MODIFIED_SINCE" client requests
Implementation is based on `BridgeAbstract::dieIfNotModified()`,
introduced in 422c125d8e and
simplified based on https://stackoverflow.com/a/10847262
Basically, before returning cached data we check if the client send
the "HTTP_IF_MODIFIED_SINCE" header. If the modification time is
more recent or equal to the cache time, we reply with "HTTP/1.1 304
Not Modified" (same as before). Otherwise send the cached data.
* [index] Don't encode exception message with `htmlspecialchars`
* [Exceptions] Include error message in exception
* [index] Show different error message for error code 0
Adds a new class 'ParameterValidator' to replace the functions from
'validator.php', separating private functions from 'validateData' to
class private functions in the process.
Instead of echoing error messages, adds messages to a private variable,
accessible via 'getInvalidParameters'.
BridgeAbstract now adds invalid parameter names to the error message.
* Group common selectors
* Fix indentation using tabs

* Use grid layout for parameters

arranged in a grid to improve readability. Read more on grid layouts

Notice:
Grid layouts are not supported in very old browser versions:
https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Grid_Layout/CSS_Grid_and_Progressive_Enhancement
This is why @supports checks for browser support (not supported in IE)
https://developer.mozilla.org/en-US/docs/Web/CSS/@supports#Browser_compatibility
In case grid layout is not supported, the displayed form is usable
but not very pretty due to <br> being removed by this commit for
cosmetic reasons (breaks grid layout).
Unfortunately it doesn't seem possible to insert line breaks manually
via '::after { content: '\A' }' in cases where grid layout isn't
supported.
* Add padding to card parameters
Adds padding to parameters to improve readability. For bridges without
parameters (count($parameters) === 0), the parameter 'div' is no longer
created.
* Add colon ':' after label via CSS
* Capitalize first letter of label for readability
* Fix checkbox isn't aligned left
Sets the size of the checkbox to 20x20 px for good measure.

[html] Generate index and bridge cards using separate clases
Move HTML generating code from 'index.php' to 'Index.php', separating components into static functions.
Move HTML generation code for bridge cards from 'html.php' to 'BridgeCard.php', separating components into static functions.
Adds detection for servers responding with Cloudflare challenges,
throwing a server error if detected:
"The server responded with a Cloudflare challenge, which is not
supported by RSS-Bridge! If this error persists longer than a week,
please consider opening an issue on GitHub!"
This is supposed to support maintainers to identify broken bridges
for sites with Cloudflare enabled permanently. It doesn't circumvent
the protection in any form or shape!
The Cloudflare challenge is detected by analyzing the last response
header received from the server. If the HTTP Code is not 200 (OK)
and the server name contains 'cloudflare' ('Server: cloudflare'),
RSS-Bridge assumes the server responded with a challenge.
The header parsing is based on https://stackoverflow.com/a/18682872

cURL is a powerful library specifically designed to connect to many
different types of servers with different types of protocols. For
more detailed information refer to the PHP cURL manual:
- http://php.net/manual/en/book.curl.php
Due to this change some parameters for the getContents function were
necessary (also applies to getSimpleHTMLDOM and getSimpleHTMLDOMCached):
> $use_include_path removed
This parameter has never been used and doesn't even make sense in
this context; If set to true file_get_contents would also search
for files in the include_path (specified in php.ini).
> $context replaced by $header and $opts
The $context parameter allowed for customization of the request in
order to change how file_get_contents would acquire the data (i.e.
using POST instead of GET, sending custom header, etc...)
cURL also provides facilities to specify custom headers and change
how it communicates to severs. cURL, however, is much more advanced.
- $header is an optional parameter (empty by default). It receives
an array of strings to send in the HTTP request header.
See 'CURLOPT_HTTPHEADER':
"An array of HTTP header fields to set, in the format
array('Content-type: text/plain', 'Content-length: 100')"
- php.net/manual/en/function.curl-setopt.php
- $opts is an optional parameter (empty by default). It receives
an array of options, where each option is a key-value-pair of
a cURL option (CURLOPT_*) and it's associated parameter. This
parameter accepts any of the CURLOPT_* settings.
Example (sending POST instead of GET):
$opts = array(
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => '&action=none'
);
$html = getContents($url, array(), $opts);
Refer to the cURL setopt manual for more information:
- php.net/manual/en/function.curl-setopt.php
> $offset and $maxlen removed
These options were supported by file_get_contents, but there doesn't
seem to be an equivalent in cURL. Since no caller uses them they are
safe to remove.
Compressed data / Encoding
By using cURL instead of file_get_contents RSS-Bridge no longer has
to handle compressed data manually.
See 'CURLOPT_ENCODING':
"[...] Supported encodings are "identity", "deflate", and "gzip".
If an empty string, "", is set, a header containing all supported
encoding types is sent."
- http://php.net/manual/en/function.curl-setopt.php
Notice: By default all encoding types are accepted (""). This can
be changed by setting a custom option via $opts.
Example:
$opts = array(CURLOPT_ENCODING => 'gzip');
$html = getContents($url, array(), $opts);
Proxy
The proxy implementation should still work, but there doesn't seem
to be an equivalent for 'request_fulluri = true'. To my understanding
this isn't an issue because cURL knows how to handle proxy communication.
