In utils/nsurl.c the function nsurl__create_from_section() has a
section dealing with non-redundant ports (starting line 973).
lwc_intern_string() was being called with negative lengths and as it
takes a size_t (unsigned) so is getting passed a very large length
which causes a segfault.
this is supposed to be protected by the flag setting on line 969
however the arithmetic is all *unsigned* so the condition never
matches
(gdb) p length - (colon - pegs->at + skip)
$9 = 18446744073709551608
changing the check arithmetic to be a simple comparison against length
prevents this issue and reduces the amount of computation required.
The translated message loading is dependant on configuration of
resource location in each frontend, additionally they should have the
ability to deal with errors in this loading in a implementation
specific manner.
This also extends the message loading API to be capable of loading
from an inline memory buffer instead of from a file.
Previously this information was logged when netsurf_init was called
which might be many lines out output into the log.
It is useful to have this information at the beginning of the log to
make it easily found. In addition it makes netsurf_init less complex.
This reduces logging overhead by only calling the log output function
once instead of three times.
Additionally the nslog_gettime interface no longer needs to be
exported and the static function is directly inlined further reducing
function call overhead.
Finally the appending of a newline uses fputc instead of a full printf
call which is considerably more simple and further reduces overhead
time.
This changes the LOG macro to be varadic removing the need for all
callsites to have double bracketing and allows for future improvement
on how we use the logging macros.
The callsites were changed with coccinelle and the changes checked by
hand. Compile tested for several frontends but not all.
A formatting annotation has also been added which allows the compiler
to check the parameters and types passed to the logging.
This splits up a great deal of the win32 window code out from other
gui code. It also remove large quantities of unused and junk
variables and functions.
The non strptime fallback reading of time_t values would report
faliure if the value it read was 0 which is a valid time. This fixes
this path to only fail if there was an actual error processing the
value.
This changes the message splitting code to ensure that a translation
is generated for every different key using a specified language as a
fallback if no translation is available.
This also allows for a messages to be generated when there is no
fallback at all and when the translation is the same as the fallback
language
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.
This removes the global PDF_Password interface that had completely
bitrotted and moves it into the standard misc operation table with a
sensible defualt implementation.
This also cleans up and fixes the gtk frontend implementation of the
pdf password callback so it compiles.
Finally this moves the implementation to a sensible place alongside
the other exporters reducing target makefile complexity futher.
The die() API for abnormal termination does not belong within the core
of netsurf and instead errors are propogated back to the callers.
This is the final part of this change and the API is now only used within
some parts of the frontends
Returning an error instead of simply calling die allows more robust
error handling. Secondly initialisation may continue even if the
messages have not been loaded which is more friendly than simply
dropping dead with no communication to the user.
The netsurf.h header should *only* contain the registration, core
initialisation and finalisation methods. Version information is best
placed in its own header.
Also remove any unneeded inclusion of this header limiting it to
solely the places the relevant API is required.
