This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.
Also adds -Wwrite-strings as a warning flag in configure.ac.

Don't forbid the empty string "" in generic structures, only in taglists.
Properly allow the NULL string by adding special cases for serialising
and deserialising it. prop1=(string)NULL is the NULL string,
prop1=(string)"NULL" is the actual string with the value "NULL"
Add a bunch of vararg getter convenience functions to complement
the vararg setter functions, and a basic unit test. Fixes#534208.
API: gst_structure_get()
API: gst_structure_id_get()
API: gst_structure_get_valist()
API: gst_structure_id_get_valist()
Use string_warp/unwrap to escape delimiters, otherwise deserialisation fails.
Also move GST_ASCII_IS_STRING to private header to avoid keeping it in sync.
Also use '\0' when terminating a string for better readability.
Also warn if an element or application tries to add a field with an
empty string to a structure (NULL strings are still needed and
allowed though) and do all those checks in the right function.
Fixes#559643.
Original commit message from CVS:
Patch by: Olivier Crete <tester at tester dot ca>
* gst/gststructure.c:
(gst_structure_fixate_field_nearest_fraction):
Avoid overflows in fixation code when dealing with MAXINT values, which
v4l2src seems to do.
Fixes#546328.
* tests/check/gst/gststructure.c: (GST_START_TEST):
Make a unit test to check the fix.
Original commit message from CVS:
2008-03-03 Andy Wingo <wingo@pobox.com>
* tests/check/gst/gststructure.c (GST_START_TEST): Add a check for
the new warning.
* gst/gststructure.c (gst_structure_from_string): Warn if
structure_from_string didn't consume the whole string, but the
caller did not provide an end pointer.
Original commit message from CVS:
* gst/gst.c:
_gst_trace_on is already provided by gsttrace.h, no need to declare
it ourselves.
* docs/libs/gstreamer-libs-sections.txt:
Add 'buffers', 'check_cond' and 'check_mutex' from libgstcheck
and remove strange tcase_add_test which is outputting a warning.
* libs/gst/check/gstcheck.c:
* libs/gst/check/gstcheck.h:
Properly declare 'buffers', 'check_cond', 'check_mutex' extern
and define them in gstcheck.c instead of having every .c file whcih
includes gstcheck.h be defining its own copy and relying on symbol
interposing to marry them all, which doesn't work on Solaris.
* tests/check/elements/identity.c: (GST_START_TEST):
Don't define 'buffers' locally, it comes from libgstcheck.
* tests/check/generic/sinks.c: (send_buffer):
Fix type of variable (GstFlowReturn, not GstStateChangeReturn)
* tests/check/gst/gststructure.c: (GST_START_TEST):
* tests/check/gst/gstsystemclock.c: (GST_START_TEST):
* tests/check/gst/gstutils.c: (GST_START_TEST):
* tests/check/gst/gstvalue.c: (GST_START_TEST):
Add a bunch of casts to make various constants fit the types
they're being assigned to.
Original commit message from CVS:
* gst/gststructure.c: (gst_structure_validate_name),
(gst_structure_new_valist), (gst_structure_parse_value),
(gst_structure_from_string):
Don't crash in _from_string() if the structure name is not valid
(fixes#501560). Allow structure names to start with a number
again (this apparently broke the ubuntu codec installer).
* tests/check/gst/gststructure.c: (GST_START_TEST), (GST_START_TEST),
(GST_START_TEST):
Add unit test for the crash; update unit tests for new behaviour.
Original commit message from CVS:
* gst/gstevent.c:
Little documentation improvment.
* gst/gstpreset.c:
More TODO cleanups. Remove c++ comments.
* libs/gst/controller/gstcontroller.c:
Add TODO and use quark from static string.
* tests/check/gst/gstmessage.c:
* tests/check/gst/gststructure.c:
Use quark from static string.
Original commit message from CVS:
* tests/check/gst/gststructure.c: (test_to_string):
Disable test that checks that white spaces are not allowed
in structure names or field names, since we need to
support that for now for backwards compatibility reasons.
Original commit message from CVS:
* gst/gstcaps.c: (gst_caps_to_string),
(gst_caps_from_string_inplace):
* gst/gststructure.c: (gst_structure_get_abbrs),
(gst_structure_to_string), (gst_structure_from_string):
* gst/gstvalue.c: (gst_value_set_structure),
(gst_value_get_structure), (gst_value_serialize_structure),
(gst_value_deserialize_structure), (_gst_value_initialize):
* gst/gstvalue.h:
* tests/check/gst/gststructure.c: (GST_START_TEST),
(gst_structure_suite):
* tests/check/gst/gstvalue.c: (GST_START_TEST):
Added GstStructure to gst_value_table and its related functions.
Changed gst_structure_to_string to print ';' in the end.
Changed gst_caps_to_string to not print ';' beteween its
fields (structures) anymore and remove the lastes ';' from latest
structure. Now it is possible to have nested structures.
In addition, backward compatibilty is assured by accepting '\0' as
end delimiter. Fixes: #487969.
API: add gst_value_set_structure()
API: add gst_value_get_structure()
Original commit message from CVS:
* gst/gststructure.c:
* tests/check/gst/gststructure.c:
Revert serialisation change and constrain structure-names after
consensus on irc. Update api documentation to reflect the change.
Original commit message from CVS:
* gst/gststructure.c:
Improve serialization and fix tests.
* tests/check/gst/gststructure.c:
Add another test that covers why I actually did the previous structure
change.
Original commit message from CVS:
* tests/check/gst/gststructure.c:
Add unit test for escaping of structure name when serialising
and deserialising to/from strings.
Original commit message from CVS:
* gst/gststructure.c:
(gst_structure_fixate_field_nearest_fraction):
Fix fraction list fixation code. Take the fraction with the smallest
difference with the target instead of the first one in the list.
* tests/check/gst/gststructure.c: (GST_START_TEST),
(gst_structure_suite):
Added test to verify correct fraction list fixation behaviour.
Original commit message from CVS:
* gst/gststructure.c: (gst_structure_parse_value):
When deserialising foo=bar without a type cast, check if it's a
boolean before falling back to a string type, otherwise things like
audiotestsrc ! audio/x-raw-int,signed=true ! fakesink won't work,
because the filtercaps end up having a signed=(string)true field,
which causes problems later when intersection caps.
* tests/check/gst/gststructure.c: (GST_START_TEST):
Add a unit test for this.
Original commit message from CVS:
* check/gst/gststructure.c: (GST_START_TEST):
* gst/gststructure.c: (gst_structure_parse_value):
Oops, broke automatic string type parsing.
Add a test to catch it in future.
Original commit message from CVS:
* check/gst/capslist.h:
Comment test cases
* check/gst/gststructure.c: (GST_START_TEST),
(gst_structure_suite):
Test automatic value type detection in gst_structure_from_string.
* gst/gststructure.c: (gst_structure_parse_value):
Add fraction as a type we try and guess automatically in
caps/structure strings.
Original commit message from CVS:
patch by: Tim-Philipp Müller <tim at centricular dot net>
* gst/gststructure.c: (gst_structure_parse_field),
(gst_structure_from_string):
Forward-port a 0.8 patch to handle escaped spaces in structure string, so that gst_parse_launch() can deal with spaces in filtered link
caps (fixes#164479)
* check/gst/capslist.h:
* check/gst/gststructure.c: (GST_START_TEST):
add unit tests for this change
Original commit message from CVS:
* check/Makefile.am:
* check/gst/capslist.h:
copy over from 0.8, and add two with bitmasks specified with
(int) 0xFF...
* check/gst/gstcaps.c: (START_TEST), (gst_caps_suite):
add test to parse everything from capslist.h
* check/gst/gststructure.c: (START_TEST), (gst_value_suite),
(main):
add test for structure deserialization
* check/gst/gstvalue.c: (START_TEST), (gst_value_suite):
add tests for deserialization of strings to int types
* gst/gststructure.c: (gst_structure_nth_field_name):
* gst/gststructure.h:
add a way to get the name of a field referenced by index
* gst/gstvalue.c: (gst_value_deserialize_int_helper):
instead of checking if the resulting long long lies between
min and max, we check if the long long would fit into
a number of bytes for the final type.
This fixes cases where a string represents 2^32 - 1, which
when cast to int would be the (valid) -1, but is bigger than
G_MAXINT
