| | | | | | | | | The future goal would be to change the version for each Ceph major release to ensure C++ applications will need to be recompiled against the librados C++ API since we don't guarentee ABI stability.

| | | | | | | | | | | | | | | | | | | | | | Fixes: https://tracker.ceph.com/issues/22159 Fixes: https://tracker.ceph.com/issues/20870 This adds more parameters to estimate allocation granularity overhead and compression effectiveness. RAW_USED column has been removed. USED column reflects amount of space allocated for a pool at all replicas. Including allocaction granularity overhead and taking ompression savings and object content gaps into account. Following columns were appended: * STORED - approximation of bytes users've actually stored in a pool, i.e netto data amount without compression, allocation and other overheads (not applicable for 'rados df'). * USED COMPR - amount of bytes allocated to store compressed data, i.e. compressed data plus allocation/replication overhead. * UNDER COMPR - amount of data(icluding repicated one) passed through compression and stored in that form.

* librados: move C++ APIs into libradosppKefu Chai2018-11-018-3026/+3146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the goal is to decouple C++ API from C API, and to version them differently, as they are targeting different consumers. this allows us to change the C++ API and bumping up its soversion without requiring consumer to recompile the librados client for using the new librados. in this way, C++ API can move faster than C API. for example, if bufferlist interface is changed for better performance, and this breaks existing API/ABI, we can bump up the C++ library's soversion, and and the C library's version unchanged but ship the new librados's C binding. so the librados client linked against librados's C library will be able to take advantage of the improvement in C++ library. while the librados client linked against C++ library won't break at runtime due to unresolved symbol or changed structure layout. this is massive change, the genereal idea is to * split librados.cc into two source files: librados_c.cc and librados_cxx.cc, the former for implementing C APIs, the later for C++ APIs. * extract the C++ API in librados into librados-cxx, the library name will be libradospp. but we can change it before nautilus is released. * link these librados libraries with static libraries which it depends on, so "-Wl,--exclude-libs,ALL" link flags can help hide the non-public symbols. * extract the tests exercising librados' C++ API into a different source file named *_cxx.cc. for instance, to move the C++ tests in aio.cc into aio_cxx.cc * extract the shared helper functions which do not use any librados or librados-cxx APIs into test_shared{.cc,h}. the "shared" here means, *shared* by C++ and C tests. * extract the test fixtures, i.e., the subclasses of testing::Test, for testing C++ APIs into testcase_cxx.cc. * update qa/workunits/rados/test.sh accordingly to add the splitted tests * update the consumers of librados to link against librados-cxx instead, if they are using the C++ API.

* librados: move get_inconsistent_pgs() into RadosClientKefu Chai2018-11-013-74/+65
| | | | | | | | | | | | so we don't need parse the pg string and render it again for librados C API. the downside of this change is that, get_inconsistent_pgs() could be implemented using RadosClient, instead be *in* it. but before we have a place for the helper functions for these higher-level functions, RadosClient is a good place for hosting them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - do not link libkv with ALLOC_LIBS, it turns out that if we link tcmalloc *before* -static-libstdc++ -static-libgcc, libstdc++ and gcc libs will show up in `ldd` output - add `-static-libstdc++ -static-libgcc` to CMAKE_SHARED_LINKER_FLAGS and CMAKE_EXE_LINKER_FLAGS instead of adding them to all shared libraries and executable. simpler this way. - link against libtcmalloc statically, because libtcmalloc is a C++ library, linking against it dynamically and linking against C++ runtime statically will pull in depdencies on two versions of C++ runtime, which will bring down the app at run-time. - do not pass '-pie' to linker when building executable if `WITH_STATIC_LIBSTDCXX` and tcmalloc is used, because the static tcmalloc is not compiled with PIC. - only apply '-pie' if ENABLE_SHARED is enabled.

* | common,rbd,rgw,osd: extract config values into ConfigValuesKefu Chai2018-07-102-25/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this change introduce three classes: ConfigValues, ConfigProxy and ConfigReader. in seastar port of OSD, each CPU shard will hold its own reference of configuration, and upon changes of settings, each shard will be updated with the new setting in async. so this forces us to be able to keep two set of configuration at the same time. so we need to extract the changeable part of md_config_t out. so we can replace the old one with new one on demand, and let different shards share the same unchanged part, amon the other things, the Options map and the lookup tables. that's why we need ConfigValues. we will add a policy template for this class, so we can specialize for Seastar implementation to allow different ConfigProxy instances to point md_config_impl<> to different ConfigValues. because the observer interface is still using md_config_t, to minimise the impact of this change, handle_conf_change() and handle_subsys_change() are not changed. but as it accepts a `const md_config_t`, which cannot be used to create/reference the ConfigProxy holding it, we need to introduce ConfigReader for reading the updated setting from md_config_t in a simpler way, without exposing the internal "values" member variable.
