2015-10-24sd-*.h: clean up exported (or to-be-exported) header filesLennart Poettering
Exported header files should not include internal headers. Fix that. Exported header files should not use the bool type. So far we opted to stick to C89 for exported headers, and hence use "int" for bools in them. Continue to do so. Exported header files should have #include lines for everything they use including inttypes.h and sys/types.h, so that they may be included in any order. Exported header files should have C++ guards, hence add them. Exported header files should not use gcc extensions like #pragma once, get rid of it.
2014-12-12hwdb: fix dangling 'else' ambuguityDavid Herrmann
Imagine the following use of hwdb: if (condition_A) SD_HWDB_FOREACH_PROPERTY(hwdb, modalias, key, value) operation_A(key, value); else log_error("..."); This should work just fine, but but definitely does not what you would expect. Due to how SD_HWDB_FOREACH_PROPERTY is defined, the dangling 'else' is linked to the hidden 'if' statement in the macro instead of the outer 'if (condition_A)'. This is unexpected and really annoying to debug. Fix this by never leaving un-finished if-statements in SD_HWDB_FOREACH_PROPERTY(). We simply inverse the if() statement and explicitly add an 'else'-branch. This way, the statement is closed and all ambuguities are resolved.
2014-12-12hwdb: FOREACH_HWDB_PROPERTY -> SD_HWDB_FOREACH_PROPERTYDavid Herrmann
Lets not pollute the global namespace. Prefix all our exported names and macros with SD_HWDB_*.
2014-12-11libsystemd: add sd-hwdb libraryTom Gundersen
This is libudev-hwdb, but decoupled from libudev and in the libsystemd style. The core code is unchanged, apart from the following minor changes: - hwdb.bin located in /**/systemd/hwdb/ take preference over the ones located in /**/udev/ - properties are stored internally in an OrderedHashmap, rather than a linked list. - a new API call allows individual properties to be queried directly, rather than iterating over them all - the iteration over properties have been moved inside the library, rather than exposing a list directly - the unused 'flags' parameter was dropped
