For some patterns of JSON we return to parse at the outermost level and
meet a situation path_match is 0. In some places we're looking at things
from perspective of path_match - 1... that does not seem to cause trouble on
x86_64 but can on aarch64, which is how it got noticed.
This logically protects those accesses by checking !!path_match.
There's a good pattern that's encouraged by using lws_struct pieces, that
we have an lws_dll2 owner with an array of objects listed in it that exist
in an lwsac. And because it came from JSON, there is tending to be a
logical name for the objects.
This adds a typed helper and wrapper to scan the owner list looking for
a specific name (of a specified length, not NUL terminated) in a specific
member of the listed objects, which must be a NUL-terminated const char *.
Again this is a good pattern that's encouraged by use of lws_tokenize
to recover the name we're looking for.
So it leads to the helper that can cleanly search for a listed object of the
right name from an owner, and return the typed object pointer or NULL, from a
length-specified string.
Replace the bash selftest plumbing with CTest.
To use the selftests, build with -DLWS_WITH_MINIMAL_EXAMPLES=1
and `CTEST_OUTPUT_ON_FAILURE=1 make test` or just
`make test`.
To disable tests that require internet access, also give
-DLWS_CTEST_INTERNET_AVAILABLE=0
Remove travis and appveyor scripts on master.
Remove travis and appveyor decals on README.md.
Add support for blob type in sqlite3... it's unusual in that it
is created into the table schema as a column of blob type, but is
not serialized or deserialized into or from JSON or sqlite.
Because the size of blobs is open-ended, accessing them in one
hit may not be possible, eg, exceed the size of available heap.
As binary, they would have to be base64-encoded in JSON
representation and that bloating may be excessive, with, eg,
a 500MB blob. So while they can be defined using lws_struct
schema, and coexist inside a column of a table managed by
lws_struct, they must be read and written separately.
Continue with lws_struct, add sqlite support for one
level of lws_dll2_t lists of structs serialization and
deserialization, plus the matching api-test.
