Mountian Lion causes various different warnings to be given,
possibly because a change to clang by default. Fix them here.
|
|
Rather than specifically checking for the nesting getting too deep and
hence throwing an error, the error handling should do this for itself.
Make it so that we spot the depth being too great in the fz_try() and
throw to the fz_catch().
|
|
Previously we would run out of error stacks in the context and fail abruptly.
Now, throw an exception and hope for the best. At least this plugs any memory
leaks.

Attempt to separate public API from internal functions.

|
On Apple OSs setjmp/longjmp also mess with the signal handlers;
we don't use signals, so we don't need the slowdown this causes.
CLUSTER_UNTESTED as not tested on cluster.

Add explanations of how to use the macros in fitz.h.
Also included are 2 different formulations, with different strengths/
weaknesses for reference. Will remove these shortly, but I want a
reference to them in git.
Workaround bug in Mac OS Lion gcc (clang works fine).

Thanks to Zeniko for pointing this out.

Include android headers in fitz.h so we can debug.
Arrange for error throwing to output to android error stream as
well as stderr.
Change jpeg library to not use backing store. Solves bug 692473.
|
|
Also: use 'cannot' instead of 'failed to' in error messages.

When using exceptions (which are implemented using setjmp/longjmp), we
need to be careful to ensure that variable values get written back
before any exception happens.
Previously we've done that using volatile, but that produces nasty
warnings (and unduly limits the compilers freedom to optimise). Here
we introduce a new macro fz_var that passes the address of the variable
out of scope. This means that the compiler has to ensure that any
changes to its value are written back to memory before calling any
out of scope function.
|
|
The failed flag can be removed by having the fz_throw (and fz_rethrow)
functions do the popping of the stack.

Import exception handling code from WSS, modified to fit into the
fitz world.
With this code we have 'real' fz_try/fz_catch/fz_rethrow functions,
handling a fz_except type. We therefore rename the existing fz_throw/
fz_catch/fz_rethrow to be fz_error_make/fz_error_handle/fz_error_note.
We don't actually use fz_try/fz_catch/fz_rethrow yet...

The run-together words are dead! Long live the underscores!
The postscript inspired naming convention of using all run-together
words has served us well, but it is now time for more readable code.
In this commit I have also added the sed script, rename.sed, that I used
to convert the source. Use it on your patches and application code.
