d4e867f240 core: Move default bridges to whitelist.default.txt
Default bridges are currently statically defined in index.php, which
is not the right place if we want to keep responsibilities separated.

This commit introduces a new file whitelist.default.txt that holds
the default bridges and which is loaded automatically, if whitelist.txt
doesn't exist.

Due to this it is also no longer necessary to have write permission
for the root directory.

core: Add FeedItem class (#940)
Add transformation from legacy items to FeedItems, before transforming
items to the desired format. This allows using legacy bridges alongside
bridges that return FeedItems.

As discussed in #940, instead of throwing exceptions on invalid
parameters, add messages to the debug log instead

Add support for strings to setTimestamp(). If the provided timestamp
is a string, automatically try to parse it using strtotime().

This allows bridges to simply use `$item['timestamp'] = $timestamp;`
instead of `$item['timestamp'] = strtotime($timestamp);`

Support simple_html_dom_node as input paramter for setURI

Support simple_html_dom_node as input parameter for setContent

49da67cb33 core: Automatically select a bridge based on a URL (#928)
* core: Add bridge parameter auto detection

This adds a new 'detect' action which accepts a URL from which an
appropriate bridge is selected and relevant parameters are extracted.
The user is then automatically redirected to the selected bridge.

For example to get a feed from: https://twitter.com/search?q=%23rss-bridge
we could send a request to:
'/?action=detect&format=Atom&url=twitter.com/search%3Fq%3D%2523rss-bridge'
which would redirect to:
'/?action=display&q=%23rss-bridge&bridge=Twitter&format=Atom'.

This auto detection happens on a per-bridge basis, so a new function
'detectParameters' is added to BridgeInterface which bridges may implement.
It takes a URL for an argument and returns a list of parameters that were
extracted, or null if the URL isn't relevant for the bridge.

* [TwitterBridge] Add parameter auto detection

* [BridgeAbstract] Add generic parameter detection

This adds generic "paramater detection" for bridges that don't have any
parameters defined. If the queried URL matches the URI defined in the
bridge (ignoring https://, www. and trailing /) an emtpy list of parameters is
returned.

a0490e3673 core: Add Debug::isEnabled() and Debug::isSecure()
Also adds documentation to Debug.php!

* Debug::isEnabled()

Checks if the DEBUG file exists on disk on the first call (stored in
memory for the duration of the instance). Returns true if debug mode
is enabled for the client.

This function also sets the internal flag for Debug::isSecure()!

* Debug::isSecure()

Returns true if debuging is enabled for specific IP addresses, false
otherwise. This is checked on the first call of Debug::isEnabled().
If you call this function before Debug::isEnabled(), the default value
is false.

e2dfea2b77 [index.php] Filter parameter '_error_time' from queries
The parameter is used in error feeds. Since RSS-Bridge returns valid
feeds for error conditions, feed readers may attempt to access the
URI returned for the feed item in order to collect additional data,
thus including the parameter '_error_time' in the query.

This results in another error message, because it is an invalid input
parameter. Filtering the parameter allows RSS-Bridge to return the
original feed.

a508dddb36 [core] Fixed broken caching (#880) 2018-10-22 19:14:49 +02:00
LogMANOriginal
b90bcee1fc
Return exceptions in requested feed formats (#841)
* [Exceptions] Don't return header for bridge exceptions
* [Exceptions] Add link to list in exception message

This is an alternative when the button is not rendered
for some reason.

* [index] Don't return bridge exception for formats
* [index] Return feed item for bridge exceptions
* [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.

References https://github.com/RSS-Bridge/rss-bridge/issues/814#issuecomment-420876162

* [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

e3a5a6a170 [index] Update and improve parameter handling for bridge and cache
- Use 'array_diff_key' instead of 'unset'
- Remove parameters for caches

By removing certain parameters for caches, the loading times can be
improved considerably:

* action: It doesn't matter which action the user took to generate
feed items.

* format: This has the biggest impact on performance, because cached
items are now shared between different formats (i.e. try switching
between Atom, Html and Mrss and compare previous vs. now). If a
server handles lots of requests, this may even reduce bandwidth if
the same contents are requested for different formats.

* _noproxy: The proxy behavior has no impact on the produced items,
so it can be ignored.

* _cache_timeout: This is another option which might impact performance
for some servers, especially if 'custom_timeout' has been enabled in
the configuration. Requests with different cache timeouts no longer
result in separate cache files.
