Add gzip compression/decompression filters for C.
2018-08-14 14:56:59 -04:00
/***********************************************************************************************************************************
Rename "gzip" to "gz". "gz" was used as the extension but "gzip" was generally used for function and type naming. With a new compression format on the way, it makes sense to standardize on a single abbreviation to represent a compression format in the code. Since the extension is standard and we must use it, also use the extension for all naming.

Add infrastructure for multiple compression type support. Add compress-type option and deprecate compress option. Since the compress option is boolean it won't work with multiple compression types. Add logic to cfgLoadUpdateOption() to update compress-type if it is not set directly. The compress option should no longer be referenced outside the cfgLoadUpdateOption() function. Add common/compress/helper module to contain interface functions that work with multiple compression types. Code outside this module should no longer call specific compression drivers, though it may be OK to reference a specific compression type using the new interface (e.g., saving backup history files in gz format). Unit tests only test compression using the gz format because other formats may not be available in all builds. It is the job of integration tests to exercise all compression types. Additional compression types will be added in future commits.

Improve type safety of interfaces and drivers. The function pointer casting used when creating drivers made changing interfaces difficult and led to slightly divergent driver implementations. Unit testing caught production-level errors but there were a lot of small issues and the process was harder than it should have been. Use void pointers instead so that no casts are required. Introduce the THIS_VOID and THIS() macros to make dealing with void pointers a little safer. Since we don't want to expose void pointers in header files, driver functions have been removed from the headers and the various driver objects return their interface type. This cuts down on accessor methods and the vast majority of those functions were not being used. Move functions that are still required to .intern.h. Remove the special "C" crypto functions that were used in libc and instead use the standard interface.

IoWrite *write = ioBufferWriteNew(compressed);
Allow protocol compression when read/writing remote files. If the file is compressible (i.e. not encrypted or already compressed) it can be marked as such in storageNewRead()/storageNewWrite(). If the file is being read from/written to a remote it will be compressed in transit using gzip. Simplify filter group handling by having the IoRead/IoWrite objects create the filter group automatically. This removes the need for a lot of NULL checking and has a negligible effect on performance since a filter group needs to be created eventually unless the source file is missing. Allow filters to be created using a VariantList so filter parameters can be passed to the remote.

Buffer *input = bufNewC(
Various Buffer improvements. Add bufDup() and bufNewUsedC(). Arrange bufNewC() params to match bufNewUsedC() since they have always seemed backward. Fix bufHex() to only render the used portion of the buffer and fix some places where used was not being set correctly. Use a union to make macro assignments for all legal values without casting. This is much more likely to catch bad assignments.

Add infrastructure for multiple compression type support. Add compress-type option and deprecate compress option. Since the compress option is boolean it won't work with multiple compression types. Add logic to cfgLoadUpdateOption() to update compress-type if it is not set directly. The compress option should no longer be referenced outside the cfgLoadUpdateOption() function. Add common/compress/helper module to contain interface functions that work with multiple compression types. Code outside this module should no longer call specific compression drivers, though it may be OK to reference a specific compression type using the new interface (e.g., saving backup history files in gz format). Unit tests only test compression using the gz format because other formats may not be available in all builds. It is the job of integration tests to exercise all compression types.

Fix segfault on unexpected EOF in gzip decompression. If the compressed stream terminated early then the decompression process would get a flush request (NULL input buffer) since the filter was not marked as done. This could happen on a zero-length or truncated (i.e. invalid) compressed file. Change the existing assertion to an error to catch this condition in production gracefully.
