This cache manages multiple http clients and returns one to the caller that is not busy. It is the responsibility of the caller to indicate when they are done with a client. If returnContent is set then the client will automatically be marked done.
Also add special handing for HEAD requests to recognize that content-length is informational only and no content is expected.
Allows listing repo paths/files from the command-line, to be used primarily for testing and debugging.
This command is internal-only so the interface may change at any time without notice.
Not all storage types support paths as a physical thing that must be created/destroyed. Add a feature to determine which drivers use paths and simplify the driver API as much as possible given that knowledge and by implementing as much path logic as possible in the Storage object.
Remove the ignoreMissing parameter from pathSync() since it is not used and makes little sense.
Create a standard list of error messages for the drivers to use and apply them where the code was modified -- there is plenty of work still to be done here.
This is just the part of restore run by the local helper processes, not the entire command.
Even so, various optimizations in the code (like pipelining and optimizations for zero-length files) should make the restore command faster on object stores.
Most of the *Free() functions are pretty generic so add macros to make creating them as easy as possible.
Create a distinction between *Free() functions that the caller uses to free memory and callbacks that free third-party resources. There are a number of cases where a driver needs to free resources but does not need a normal *Free() because it is handled by the interface.
Add common/object.h for macros that make object maintenance easier. This pattern can also be used for many more object functions.
Add GLUE() macro which is useful for creating identifiers.
Move MACRO_TO_STR() here and rename it STRINGIFY(). This appears to be the standard name for this type of macro and it is also an awesome name.
Remove "File" and "Driver" from object names so they are shorter and easier to keep consistent.
Also remove the "driver" directory so storage implementations are visible directly under "storage".
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.
Use autoconf to provide a basic configure script. WITH_BACKTRACE is yet to be migrated to configure and the unit tests still use a custom Makefile.
Each C file must include "build.auto.conf" before all other includes and defines. This is enforced by test.pl for includes, but it won't detect incorrect define ordering.
Update packages to call configure and use standard flags to pass options.
