The generic bitmap handlers provided by each frontend are called back
from the core and therefore should be in an operation table. This was
one of the very few remaining interfaces stopping the core code from
being split into a library.
The content thumbnailers for each frontend were being provided the
contents url. This was only ever used to call the urldb thumbnail
setting API.
This changes it so the single callsite that passed a valid url adds
the bitmap to that url itself in desktop_history.c instead of forcing
every frontend to require the urldb API.
Additionally the old API could pass the url as NULL which was causing
asserts where this was not an expected parameter value. Because of
this this fixes bug #2286 which was also present in the monkey
frontend as both called nsurl_access() on the url without the NULL
check and caused an assertion.
If saving hotlist to "<path>", we now save to "<path>.bk", then remove
the file at "<path>", and replace it with the one at "<path>.bk".
This should prevent hotlist corruption when someone pulls the plug
while the hotlist is being written.
The cocoa frontend was directly acessing browser internals instead of
using the API. In the case of gui.m there was a check for the browser
window not being root (browser->parent != NULL) . As gui windows can
only ever be associated with the root brower window (i.e. its parent
will always be NULL) this was completely redundant.
By hiding all but the form selection menu option structure from code
outside of render this reduces the API to the absolute minimum to
support this feature.
CERT MEM04-C suggests that zero length allocations behaviour might be
surprising so it should be avoided. This adds a check to ensure a zero
length allocation will be avoided. Additionally it returns errors to
the caller rather than warning directly (in some error paths)
Previously content handler debugging features were accessed by global
variables. This allows the setting of debugging parameters via a
content API giving per content control over debugging features.
Currently only used by the html content handler to toggle global
redraw debugging.
The frontends previously had to use an html renderer API to get the
encoding of a content. This also required the explicit checking of the
contents type rather than using the existing content API to abstract
this knowledge.
This cleans up this header and moves the functionality into more
useful places while reducing the include complexity but only pulling
in whats required.
Update the API which allows frontends to acquire the page features
(images, link urls or form elements) present at the given coordinates
within a browser window.
By making this an explicit browser_window API and using the browser.h
header for the associated data structure with a more appropriate API
naming the usage is much more obvious and contained.
Additionally the link url is now passed around as a nsurl stopping it
being converted from nsurl to text and back again several times.
