449bf0bb7b [script] Silence incorrect compiler warnings 
Bah, the compiler failed to do its IPA correctly and wrongly complained
about potential use of uninitialised out-params guarded by the return
value. Silence them!

0df43251d4 [replay] Take advantage of unresolved fonts 
As Behdad has changed the underlying ft-font to accept unresolved patterns,
take advantage of that to simplify the replay code.

aa65e756d4 [script] Avoid creating 0x0 windows 
XCreateWindow dies if asked to create a 0x0 window, so don't and use a 1x1
pixel window for a zero-sized surface.

83f0e6cf62 [script] Inline the stack push 
Frequently to push an object onto the stack all we need is to simply
perform the struct copy - so inline it and only call the out-of-line
function if we need to enlarge the stack.

265ebd372a [script] Flesh out the relational comparison operators to be more PostScript-like. 
The relational comparison operators can now compare strings vs names
by content as well as performing automatic type promotions on the
numeric types.  For other types relational comparisons succeeed
only if the values compare equal according to the eq operator, and
put the interpreter into a type-error state otherwise.

05afec7a8a [script] Implement the ne operator. 2008-12-12 12:00:41 +00:00
M Joonas Pihlaja
1aeb96dc28 [script] Implement PostScript-like semantics for the eq operator. 
The eq operator would only work for some types and put the
interpreter in an error state if passed objects it didn't
know how to compare.  It would also not compare strings
by value nor allow strings to be compared to names.
This patch makes any two objects comparable.

disabled. Fix.

41cb91d417 [script] Use the in-tree libcairo for csi-replay. 
csi-replay was missing the in-tree libcairo.la so the build was
failing while looking for new symbols from the system libcairo.

5591cb58fd [script] Only use zlib if available. 
Conditionally link against zlib - replaying a script will fail if the
trace uses a compressed format.

9432c0c9b8 [script] Link the interpreter against the built library.

815e5b962e [script] Add a fallback image surface for replay 
If we do not have a native windowing surface compiled into the library,
just replay the script to an image surface.

1f44fb97f3 cairo-script: add $(top_builddir)/src to CPPPATH. 
$(top_builddir)/src is needed to find cairo-features.h while
building out of tree.

0d5e533b6c [trace] Correctly push font-face onto the operand stack. 
We tried to push a reference to an undefined font-face, now we just copy
from the operand stack.

conditionally include byteswap.h and provide fallback implementations.

91c17d3332 [trace] Simple unbounded cache for symbol lookups. 
Reparsing the dwarf info for every lookup is very slow, so cache the
symbol lookups. This initial implementation is unbounded in the simple
belief that the actual number of unique lookups during a program's
lifetime should be fairly small. (Extending to a bounded MRU list is left
as an exercise for the reader.)

cdfffc7420 Add CairoScript interpreter 
Add a CairoScript interpreter library and use it to replay the test output
for the CairoScript backend. The library is also used by the currently
standalone Sphinx debugger [git://anongit.freedesktop.org/~ickle/sphinx].
The syntax/operator semantics are not yet finalized, but are expected to
mature before the next stable release.

5f0aa27445 [trace] Add caller line info.

useful debug info to the trace.

76f249a493 [trace] Detect and report broken traces. 
We cannot trace the cairo-script-interpreter as that uses Cairo's private
symbols.

8f3d0b55f5 [trace] Add unstable warning. 
Add warning that CairoScript is unfinished and I may radically alter the
format/syntax/language before release.

7ad2635ebe [trace] Disable stdout by default.

5badcf6e37 [trace] Use a string literal for the type.

1d0faefbc8 [trace] Record the XID as a number

used.

2554d17598 [surface] Pass a separate closure for the mime-type destroy notifier. 
A limitation of the current API was that the destroy notifier was called
on the mime-data block. This prevents the user from passing in a pointer
to a managed block, for example a mime-data block belonging to a
ref-counted object. We can overcome this by allowing the user to specify
the closure to be used with the destroy notifier.

alternate representation.
