For android this means it will go to our logging. This moves
the code out of gs.
|
|
A PDF repair can be triggered 'just in time', when we encounter
a problem in the file. The idea is that this can happen without
the enclosing code being aware of it.
Thus the enclosing code may be holding 'borrowed' references
(such as those returned by pdf_dict_get()) at the time when the
repair is triggered. We are therefore at pains to ensure that
the repair does not replace any objects that exist already, so
that the calling code will not have these references unexpectedly
invalidated.
The sole exception to this is when we replace the 'Length' fields
in stream dictionaries with the actual lengths. Bug 697015 shows
exactly this situation causing a reference to become invalid.
The solution implemented here is to add an 'orphan list' to the
document, where we put these (hopefully few, small) objects. These
orphans are kept around until the document is closed.

Avoids gcc giving spurious warnings.

We need to quote profile names if we use system, but not if we
use the GS_API. Update the code to cope.
|
|
Have both the GSAPI and non GSAPI invocations be identical.
Remove the -rxx bit because it is not required when using -gWxH
and -dFitPage.
Add some simple debug code.

When reallocing set the rawsize before attempting to write
the post guard block.

Including: Bug 697134: Tweak MEMENTO_GS_HACKS inclusion.
Rather than rolling our own memset prototype in this case, use
the one that gs provides.
And, bug 697133: Fix typo in Memento.
Causing a significant slowdown. Thanks to George Burgess IV
for spotting this.

Cope with circles, rounded rects, etc. Not the worlds best
approximation to a circular arc, but it's better than nothing.

A few commits back, we introduced the fz_key_storable concept
to allow us to cope with objects that were used both as values
within the store and as parts of keys within the store.
This commit worked, but showed up performance problems; when the
store has several million PDF objects in it, bulk changes (such
as dropping a display list or document) could trigger many passes
across the store.
We therefore introduce a mechanism to ameliorate this. These
passes, now known as "reap passes", can be batched together using
fz_defer_reap_start and fz_defer_reap_end.
We trigger this start/end around display list dropping, and around
PDF content stream processing. This should be fine, as deferral
will be interrupted if we ever run our of memory during mallocing.

This is used at several places in mupdf.
|
|
fz_parse_xml() assumes a null-terminated xml string.

Applications must be able to run e.g. Document.destroy() and later
set that reference to null and have the JVM successfully run the
finalizer an arbitrary time later. Previously the JVM would fail
to do so because the finalizer would throw an exception since the
native pointer was null.

The separation class had a member renamed. Rename it here too.
|
|
|

We can use names as keys for colorspaces. These are not bound to
a particular document.
|

|
If USE_GS_API is defined, we use the gsapi interface to call
gs.
The gsapi interface is defined in iapi.h, which is not included
in the mupdf source code. We therefore include a potted version
of this API inline.
To use the original, pass HAVE_IAPI_H at compile time.

Its output directory was set differently.

If the same image is used repeatedly, then we currently send
the data again and again. Instead, send each image as a
reusable symbol and reuse it as required.
This reduces the size of the output by over 50% for the example
file, but unfortunately results in the example file killing
both Firefox and Edge when we attempt to load it. The file
seems entirely valid though, and this is a saving on sane files.
There is a #define that can be made to revert to the old
behaviour (SVG_SEND_REPEATED_IMAGES).

As reasonable a place to call it as we can hope for. If we
ever have 2 documents open and we close 1 then it will dump
more blocks than we like, but when we get to that stage we
can worry about it then.

Not used, other than for the convenience of editing/searching.

In the JNI code, we attach a cloned context onto each thread
we encounter in thread local storage. When the thread shuts
down, we should destroy that context.
This can theoretically be achieved on pthreads by using the
destructor registered to the tls slot. I have yet to see
Android ever actually call this destructor yet though.
No such mechanism exists for windows thread, so we'll just leak
here for now. There is a potential fix for this, but it's
hairy, so details are left in a comment in the code.

Now linear time rather than n^2.
|
|
When we destroy a PDF document, currently we bin everything
from the store. Instead, drop just the objects that are
specifically tied to that document.
Any object tied to the document has a pdf_obj with the
required document pointer in it as the key.
|
|
|
|
If Java code creates e.g. a Document object and later calls
Document.destroy() and then keeps using the Document object
the library would end up crashing because the native pointer
was null. This case rather special case is now handled.
|
|
The underlying pdf_dict_put() converts into a null object.
|
|
But do not check it twice.
|
|
|
|
|
|
This case can be handled gracefully since commit
2d3eca6dec6b8fc7a169b3fc357904069df6b6c4.
