The wallclock() API uses gettimeofday which can be affected by the the
systems clock being changed etc. The curl fetcher usage of this API is
to generate a timing delta and does not cope with the gettimeofday
issues.
This changes the fetcher to use the nsutils library monotonic time
function which does not suffer from the issues with gettimeofday.
The config header was causing many source files to unecessarily
include the dirent headers causing extra dependancies. This has been
fixed by providing a utility dirent header that provides a common API
across all platforms while removing the unecessary dirent header usage.
The utility configuration header dragged in a number of bsd sockets
and related API as a side effect of setting up the configuration. By
splitting the header and API setup into a separate header only the
small number of places that need the functionality explitly include
it.
The printf formatting for size_t is set in c99 as %zu but in windows
it is %Iu this is solved by adding and inttypes style PRI macro for size_t
This also uses this macro everywhere size_t is formatted.
This is an attempt to amelioriate the situation found in #2384 where
we see the cURL connect() failing to complete. Based on the pcap
from the bug log, we believe that RISC OS is likely failing to signal
the completion of the connection to cURL. As such, cURL times out.
This change permits retries of timed out connections in the hope that
a fresh socket FD might subsequently function correctly. The defaults
chosen mean that the previous behaviour of 30 seconds before timeout
is reported will remain the same, but in that time we will make 3 separate
attempts to connect the socket.
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 data scheme fetcher was over allocating the space for decoded
base64 encoded urls and not using the base64 API that allocated the
correct size storage.
By using an error code return we can gracefully handle fetcher
registration faliures instead of just immediately aborting.
The curl handler was also cleaned up and documentation improved
as a side effect.
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.
This rationalises the path construction and basename file
operations. The default implementation is POSIX which works for all
frontends except windows, riscos and amiga which have differeing path
separators and rules.
These implementations are significantly more robust than the previous
nine implementations and also do not use unsafe strncpy or buffers
with arbitrary length limits.
These implementations also carry full documentation comments.
