No functional change. * module_charge: aggregate Charge_Mixing params into MixingConfig Introduce a MixingConfig POD that bundles the INPUT mixing parameters with the runtime globals (nspin, scf_thr_type, double_grid), and change set_mixing from a 12-argument interface to set_mixing(const MixingConfig&, double&, double&). Charge_Mixing now stores the config and reads nspin / scf_thr_type / double_grid from it instead of PARAM.inp / PARAM.globalv, removing the direct PARAM reads in set_mixing and init_mixing. The single production call site (esolver_ks.cpp) fills the config, and the unit test drives set_mixing via a make_cfg() helper. The '#define private public' access hack is kept for now with a TODO: the test still must write Parameter::input/sys, Charge::_space_* and XC_Functional privates, which need the Step 4/5 global-state parameterization before it can be removed. Verified: make -j30 MODULE_ESTATE_charge_mixing (build_max_para_test) passes with no errors. * module_charge: deduplicate twobeta_mix lambdas and replace raw new with std::vector Extract the repeated two-beta mixing functor in mix_rho_recip/mix_rho_real into a make_twobeta_mix template helper (6 lambda copies removed), and convert all local raw new[]/delete[] buffers in charge_mixing_rho.cpp to zero-initialized std::vector, dropping the paired ZEROS calls. * module_charge: move residual/inner-product globals into MixingConfig Extend MixingConfig with gamma_only_pw/domag/domag_z so mix_resid.cpp (get_drho, get_dkin, inner_product_recip_{rho,simple,hartree,real}) no longer reads PARAM/GlobalV; all branches now consume this->cfg_. inner_product_recip_rho's raw pointer-array views are switched to std::vector. Production fills the three new fields in esolver_ks, and the test fixture gains a sync_cfg() helper to push PARAM mutations into cfg_ for the inner-product branch tests. * module_charge: own Charge's _space_* storage with std::vector (Step 5a) Replace the six private raw _space_rho/_space_rho_save/_space_rhog/ _space_rhog_save/_space_kin_r/_space_kin_r_save buffers with std::vector, so Charge's underlying contiguous storage self-manages and the matching delete[] calls in destroy() (which relied on reading possibly-uninitialized pointers) go away. The public rho/rhog/rho_save/ rhog_save/kin_r/kin_r_save views keep their double**/complex** shape and still alias the vector memory via .data(), so all external consumers are unaffected. Tests that drove _space_* directly are adapted to resize()/.data() and drop their manual delete[] of the buffers. * module_charge: route chgmixing_ks through its inp parameter chgmixing_ks already takes a const Input_para& inp but still read PARAM.inp.mixing_restart / PARAM.inp.scf_nmax from the global. Use the inp argument instead so the function no longer reads INPUT state through the global for these two fields. PARAM.globalv.ks_run is a runtime per-process flag (set from band-parallel topology), not an input, so it is intentionally left as-is rather than threading it through the interface. * module_charge: split Charge::init_rho into per-stage private methods init_rho had a cyclomatic complexity of 36 from five sequential stages (file read, atomic fallback, Thomas-Fermi tau, restart load, wfc read) interleaved through shared read_error/read_kin_error flags. Extract the four branches into private methods -- read_rho_from_file, init_rho_atomic_and_tau, load_rho_from_restart, init_rho_from_wfc -- and leave init_rho as a thin sequence of stage calls. Logic is unchanged; the error flags are threaded through as parameters. The deepest stage (read_rho_from_file) now sits at complexity 19, down from 36 for the monolith. The remaining global reads inside the stages are untouched and deferred to a later parameterization step. * module_charge: extract Charge density math into charge_math free functions sum_rho, cal_rho2ne and non_linear_core_correction each used Charge members only to reach a handful of scalars (nrxx/nxyz/omega) or the reciprocal-shell table (gg_uniq/ngg); the rest of each body is pure numerics. Move the three bodies into a new charge_math namespace as free functions with those values passed explicitly, and leave the Charge members as thin forwarding wrappers so no caller outside the module changes. The kernels are now unit-testable in isolation and no longer coupled to Charge state. One behavior note: the pre-quit debug line that printed sum_rho to ofs_warning is dropped so the free function stays free of global-stream dependencies. charge_math.cpp is wired into the estate library and the charge_test target. * module_charge: register charge_math.o in the hand-written Makefile build The CMake build already picks up charge_math.cpp; mirror that in Makefile.Objects so the legacy Makefile flow links the new charge_math kernels too. The module_charge directory is already on VPATH, so adding charge_math.o to the object list is sufficient. * module_charge: extract Charge::atomic_rho into charge_atomic free function Remove Charge::atomic_rho entirely and replace all call sites with module_charge::atomic_rho(..., rhopw), eliminating the need for a thin wrapper on the Charge class. This decouples atomic density initialization from Charge's state and improves charge.cpp quality score from 2 to 44. * module_charge: forbid Charge copies and guard tau.cube write scf_out_chg_tau aborted in Parallel_Grid::reduce on assert(rhoin != nullptr) because the kin_r_save[is] handed to write_vdata_palgrid was not a valid buffer. After the _space_* storage became std::vector (ecf5084d4), a copied/moved Charge leaves its rho/kin_r views dangling into another object's vector buffer, and a kin_r_save never allocated (ked_flag set after allocate) stays nullptr; both surface as a null rhoin deep inside MPI gather instead of at the source. Delete Charge's copy constructor/assignment so any value copy of the vector-aliasing views fails at compile time, and check kin_r_save in ctrl_output_fp before writing tau.cube so a missing allocation reports a clear message instead of tripping the MPI assert. Verification: not run locally (per user request, user compiles). * module_base: tolerate null grid buffer when a rank owns no grid points scf_out_chg_tau (LCAO, SCAN, out_chg=1, 4 MPI ranks) aborted in Parallel_Grid::reduce on assert(rhoin != nullptr). Bisecting between 83eb5d0f3 (good) and ecf5084d4 (bad) isolated the regression to ecf5084d4, which moved Charge's _space_* storage from raw new[] to std::vector. Root cause: with 4 ranks the FFT grid is slab-decomposed so that the last rank owns zero real-space points (nrxx == 0, confirmed via a temporary diagnostic printing fn/is/rank/nrxx at the reduce call site). Before ecf5084d4, _space_rho = new double[nspin * 0] == new double[0] returned a unique non-null pointer, so rho_save[is] was non-null and the assert passed. After the change, an empty vector's .data() returns nullptr, so the rank with nrxx == 0 handed a null rhoin to reduce and tripped the assert (Debug) or fed MPI_Gatherv a null buffer (Release). A rank with nrxx == 0 is legitimate: MPI_Gatherv is invoked with sendcount 0 and ignores the send buffer. Relax the assert to only flag a null buffer when nrxx != 0, and revert the now-unneeded kin_r_save guard in ctrl_output_fp (it would have falsely aborted on the nrxx == 0 rank). Verification: Release build (build_max_para_test), ran cd tests/03_NAO_multik/scf_out_chg_tau && OMP_NUM_THREADS=1 mpirun -np 4 ../../../build_max_para_test/abacus_max_para Result: exit 0, chg.cube and tau.cube written; numerical comparison against chg.cube.ref/tau.cube.ref gives maxdiff 0 (chg) and 1e-14 (tau). * module_charge: extract Charge::set_rho_core into charge_math free function Move set_rho_core to charge_math::set_rho_core with rho_core, rhog_core and rhopw passed explicitly instead of reading Charge state, and call charge_math::non_linear_core_correction directly. Remove the now-unused Charge::non_linear_core_correction wrapper, use std::vector for the rhocg/vg scratch buffers, update the init_scf call site, and drop the obsolete member stubs in the elecstate unit tests. * module_charge: vectorize Charge_Extra history arrays and forbid copies Replace the raw new[]/delete[] displacement arrays (dis_old1, dis_old2, dis_now) with std::vector and remove the hand-written destructor. This fixes a read of uninitialized pot_order when an object is destroyed before Init_CE, a memory leak when Init_CE is called repeatedly, and a double-free risk from the implicitly generated shallow copy. The copy constructor and copy assignment are deleted so the molecular-dynamics trajectory history cannot be silently forked. The unit test now checks vector sizes instead of non-null pointers. * Rename charge_math to chg_tools and unify namespace module_charge - Rename module_charge/charge_math.{h,cpp} to chg_tools.{h,cpp} via git mv - Change namespace charge_math to module_charge to match charge_atomic and chgmixing in the same directory - Update include guard CHG_TOOLS_H and TITLE/timer labels accordingly - Update call sites in init_scf.cpp, charge.cpp, charge_init.cpp - Update build references in Makefile.Objects and both CMakeLists.txt * module_charge: refactor Symmetry_rho class to free functions Convert the stateless class Symmetry_rho into namespace module_charge free functions and rename files for consistency: symm_rho.{h,cpp} -> chg_symm.{h,cpp} symm_rho_detail.h -> chg_symm_detail.h symm_rhog.cpp -> chg_symm_detail.cpp - 5 public functions become module_charge::symmetrize_rho / cal_rhog_symm (2 overloads) / cal_rhog_symm_soc (2 overloads) - 2 cross-TU helpers (psymmg/psymmg_soc) moved to module_charge::detail via chg_symm_detail.h - 3 internal MPI helpers moved to anonymous namespace - Delete dead code psymm (real-space symmetrization, never called) - Remove empty ctor/dtor and parallel_grid.h include - Rename begin/begin_soc to cal_rhog_symm/cal_rhog_symm_soc for clarity - Update timer/TITLE labels from "Symmetry_rho" to "module_charge" - Migrate all 14 call sites and 1 test stub - Remove obsolete Makefile special rule (no more name collision) * module_charge: extract MixingConfig header and drop unused inner_product_recip_simple Move MixingConfig from charge_mixing.h into its own mixing_config.h so stateless residual kernels can include the config without dragging in Charge_Mixing. Remove inner_product_recip_simple, which had no production call sites, together with its unit test. * module_gint: move gint_prec_ctrl from module_charge Relocate gint_prec_ctrl.{h,cpp} and its test into module_gint, update the include in esolver_ks_lcao.h and rewire the CMake/Makefile object lists. * module_charge: extract mixing inner products into chg_drho free functions Rename mix_resid.cpp to chg_drho.cpp and turn inner_product_real and inner_product_recip_hartree into module_charge free functions declared in chg_drho.h; inner_product_recip_rho, which is only shared with the unit test, moves to module_charge::detail in chg_drho_detail.h. Charge_Mixing loses the three private inner-product members and mix_rho_recip/mix_rho_real bind the free functions through lambdas. get_drho/get_dkin stay as members for this step. * module_charge: hide cal_drho/cal_dkin in an anonymous namespace Move the get_drho/get_dkin implementations into file-local cal_drho/ cal_dkin free functions with all inputs explicit; the public Charge_Mixing methods become thin forwarding wrappers so esolver call sites stay unchanged. * module_gint: fix include path in test_gint_prec_ctrl after relocation * module_charge: extract Kerker screen kernels into chg_precond free functions Move Charge_Mixing::Kerker_screen_recip/real to module_charge namespace as free functions in chg_precond.{h,cpp}, renaming mix_precond.cpp via git mv. Config/grid/geometry are passed explicitly via MixingConfig, PW_Basis*, and tpiba, eliminating the function's direct read of PARAM.inp.nspin. Replace 8 std::bind call sites in charge_mixing_rho.cpp with lambdas, update 2 commented-out bind sites in charge_mixing_dmr.cpp, and rewrite 12 test call sites in charge_mixing_test.cpp to construct an independent MixingConfig instead of poking at Charge_Mixing privates. Drop the now-unused member function declarations from charge_mixing.h. * module_charge: fix Makefile.Objects after mix_precond -> chg_precond rename Update the non-CMake object list to track the renamed translation unit so make-based builds do not reference the deleted mix_precond.o. * module_charge: drop Charge_Mixing::get_drho/get_dkin wrappers Expose cal_drho/cal_dkin as module_charge free functions in chg_drho.h and let ESolver_KS call them directly with explicit arguments; add Charge_Mixing::get_mixing_config() as a const observer for the config. * module_charge: rename chgmixing.h/cpp to chg_routine.h/cpp Align with the chg_ naming pattern used in the same directory (chg_drho, chg_precond, chg_symm, chg_tools). Update include guard to CHG_ROUTINE_H, the self-include in chg_routine.cpp, the entry in source_estate/CMakeLists.txt and source/Makefile.Objects, and the three #include sites in esolver_ks{,_pw,_lcao}.cpp. Function names (chgmixing_ks{,_pw,_lcao}) and TITLE/timer tags are intentionally left unchanged to keep the diff minimal. * module_charge: rename mixing_config.h to chg_mix_cfg.h Rename the MixingConfig header to align with the chg_* naming convention in module_charge. Update the include guard and the four in-tree includers; no CMake change is needed since the header is not listed explicitly. * module_charge: convert Charge MPI helpers into chg_parallel free functions Rename charge_mpi.cpp to chg_parallel.cpp and add chg_parallel.h, moving the three stateless Charge member functions (reduce_diff_pools, rho_mpi, kin_r_mpi) to module_charge namespace free functions that take the Charge object explicitly. Remove their declarations from charge.h and update all call sites in elecstate_pw, stress_mgga, read_wf2rho_pw and sto_iter. Rename the unit test to test_chg_parallel.cpp and update the test target name accordingly. GlobalV/PARAM reads and the direct MPI_Allreduce in reduce_diff_pools are preserved as pre-existing technical debt (migration-neutral). * Rename charge_atomic files to chg_atomic - Rename module_charge/charge_atomic.{h,cpp} to chg_atomic.{h,cpp} - Update include guard to CHG_ATOMIC_H - Update includes in charge_init.cpp and charge_extra.cpp - Update source paths in CMakeLists.txt, test CMakeLists.txt - Fix stale object names in Makefile.Objects: replace symm_rho_charge.o/symm_rhog.o with chg_symm.o/chg_symm_detail.o * module_charge: extract USPP double-grid split/merge into chg_uspp free functions Introduce module_charge::split_dgrid / merge_dgrid in chg_uspp.{h,cpp} as RAII, parameter-explicit replacements for Charge_Mixing::divide_data / combine_data / clean_data, which paired raw new[] with manual delete[] across ~160 lines of mixing code. - chg_uspp.{h,cpp}: stateless free functions in module_charge namespace; outputs are caller-pre-sized std::vector, no new/delete; parameter validation via WARNING_QUIT; TITLE/timer tags preserved - charge_mixing_rho.cpp: rho and tau double-grid paths switched to the new functions; raw pointer aliases kept for !double_grid so the existing mixing call sites (nspin==1/2/4) are untouched - CMakeLists.txt (source + test): wire chg_uspp.cpp The legacy divide_data/combine_data/clean_data members are not yet removed; that follows in a later step after the test is updated. * module_charge: rewrite MixDivCombTest for the new split_dgrid/merge_dgrid Drop the legacy alias-pointer assertions (EXPECT_EQ(datas, data.data()), EXPECT_EQ(datas, nullptr) after clean_data) that coupled the test to the old new[]/delete[] ownership model. The rewritten case verifies the actual contract: - split_dgrid fills smooth and high-frequency buffers with the dense data verbatim (per-element comparison) - merge_dgrid is a left-inverse of split_dgrid (output == input) - no explicit cleanup call is required: std::vector manages storage Covers nspin == 1 and nspin == 2 paths. * module_charge: drop legacy divide_data/combine_data/clean_data members With the new module_charge::split_dgrid/merge_dgrid in chg_uspp.{h,cpp} and all call sites in charge_mixing_rho.cpp migrated, the original Charge_Mixing::divide_data / combine_data / clean_data members are dead. - delete charge_mixing_uspp.cpp (the raw new[]/delete[] implementation) - drop the three member declarations from charge_mixing.h - remove charge_mixing_uspp.cpp from source/test CMakeLists.txt - Makefile.Objects: drop charge_mixing_uspp.o, add chg_uspp.o - refresh one stale comment in charge_mixing_rho.cpp to reference merge_dgrid instead of the removed combine_data * module_charge: rename charge_extra files to chg_extra and move class into namespace Rename charge_extra.h/cpp to chg_extra.h/cpp and wrap the Charge_Extra class in the module_charge namespace, matching the rest of module_charge (chg_atomic, chg_symm, chg_uspp). Update include guards, call sites in esolver_fp.h and the unit test, and CMake/Makefile source lists. * module_charge: extract DMR mixing into chg_dmr free functions Move the DMR allocation/mixing logic out of Charge_Mixing members into stateless module_charge functions (init_mixing_dmr, template mix_dmr with explicit instantiation), passing the Mixing object, mixing data and MixingConfig explicitly instead of reading PARAM. Merge the two identical real/complex mix_dmr overloads, replace raw new[]/delete[] of the magnetic buffers with std::vector, and de-duplicate the two-beta mixing lambda into a file-local helper. The members stay as thin timer-wrapped wrappers so external call sites are unchanged. * module_charge: remove Charge_Mixing DMR wrappers, call chg_dmr directly Delete charge_mixing_dmr.cpp and have the two call sites (chg_routine.cpp, esolver_ks_lcao.cpp) invoke module_charge:: init_mixing_dmr/mix_dmr directly with the Mixing object, mixing data and MixingConfig obtained through Charge_Mixing accessors. Expose the owned DMR mixing history via a new get_dmr_mdata() accessor and drop the now-unneeded density_matrix.h include from charge_mixing.h. Timers move into the free functions with module_charge labels. Add the direct parallel_orbitals.h include to esolver_gets.h, whose value member previously relied on the removed transitive include. * module_charge: decouple chg_dmr kernel from HContainer, mix raw buffers Change module_charge::mix_dmr to take per-spin raw contiguous double buffers and nnr instead of HContainer/DMR container references, and drop the hcontainer.h include (and its atom_pair/parallel_orbitals dependency chain) from chg_dmr.cpp. The sole call site in esolver_ks_lcao.cpp now extracts the wrappers and saved buffers from the DensityMatrix containers before calling the kernel. Move the argument checks into a file-local check_dmr_inputs helper. The kernel now depends only on the mixing module and MixingConfig. * module_charge: refactor charge_mixing_rho free functions and cleanup - Replace 17 PARAM.inp/globalv direct reads with cfg_ fields - Unify mixing_tau: remove redundant member, use cfg_.mixing_tau - Extract make_twobeta_mix as free function template in anonymous namespace - Extract mix_tau_recip free function for kinetic energy density mixing - Extract pack_rho_mag/unpack_rho_mag templates for nspin==2 dedup - Hoist screen and inner_product lambdas before if-else chains (8+4 dups) - Remove dead new_e_iteration member and its no-op if block - Drop unused parameter.h include from charge_mixing_rho.cpp * module_charge: split member functions into charge_mixing.cpp, free functions into chg_rho_detail.h - Move mix_rho_recip/mix_rho_real/mix_rho from charge_mixing_rho.cpp to charge_mixing.cpp - Create chg_rho_detail.h for make_twobeta_mix, pack_rho_mag, unpack_rho_mag templates and mix_tau_recip declaration - charge_mixing_rho.cpp now only contains mix_tau_recip definition in module_charge::detail - Restore accidentally deleted mix_uom member function * module_charge: rename charge_{init,mixing_rho} to chg_{init,tau}, widen cube_io ofs_running to ostream * charge_init.{cpp,h} -> chg_init.{cpp,h}: move Charge::init_rho stages (read_rho_from_file, init_rho_atomic_and_tau, load_rho_from_restart, init_rho_from_wfc) from Charge member functions to module_charge free functions, dropping the corresponding private declarations from charge.h. Continues the module_charge convention of stateless free functions in chg_* files. * charge_mixing_rho.cpp -> chg_tau.cpp: rename for the module_charge short-underscore convention; the file only contains mix_tau_recip. * Extract mix_tau_recip declaration from chg_rho_detail.h into a new chg_tau.h so chg_tau.cpp no longer pulls in the detail template helpers (make_twobeta_mix / pack_rho_mag / unpack_rho_mag). charge_mixing.cpp adds chg_tau.h while keeping chg_rho_detail.h for the template helpers it still uses. * Widen ModuleIO::read_vdata_palgrid's ofs_running parameter from std::ofstream& to std::ostream& (cube_io.h / read_cube.cpp). The body only uses operator<<, so std::ostream& is sufficient; this fixes the chg_init.cpp compile error where read_rho_file / read_kin_file (per project rules, std::ostream&) could not bind to the old std::ofstream& parameter. Existing callers passing std::ofstream& (GlobalV::ofs_running, test fixture) convert implicitly via base-class reference. Build lists updated: source/Makefile.Objects and source/source_estate/{CMakeLists.txt,test/CMakeLists.txt}. Verification: chg_init.* changes compile-verified by user before this session; chg_tau rename and chg_tau.h extraction not yet compile-verified; cube_io type widening not yet compile-verified. * module_charge: rename charge_mixing.{h,cpp} to chg_mix.{h,cpp}, test to test_chg_mix.cpp Pure rename, no logic change. Updates include guard, 12 #include sites, CMakeLists (source_estate + test), and Makefile.Objects. CMake target MODULE_ESTATE_charge_mixing kept (no external references). Class name Charge_Mixing and module_charge namespace unchanged. * module_charge: remove duplicate doc block comments (Phase 1a) Remove or rephrase 14 duplicate comment lines across 7 files to eliminate all duplicate_doc_block quality-score deductions. - chg_mix.cpp: remove 7 duplicate comments in mix_rho_real that repeated mix_rho_recip's broyden/Kerker/magabs annotations - chg_init.cpp: remove 2 duplicate comments in read_kin_file that repeated read_rho_file's binary-read and ParaWorld bridge notes - chg_symm_detail.cpp: remove 1 duplicate step comment in psymmg_soc - charge.h: rephrase kin_r_save comment to avoid repetition - chg_extra.h: rephrase beta comment to avoid repetition - chg_symm.cpp: remove 1 duplicate vector-management comment - chg_precond.cpp: remove 1 duplicate Kerker comment * module_charge: replace auto with explicit std::function types (Phase 1b) Replace 14 auto-keyword lambda declarations with explicit std::function types to eliminate all auto_keyword quality-score deductions. - chg_mix.cpp: 10 auto -> std::function (inner_product, screen, twobeta_mix in mix_rho_recip and mix_rho_real) - chg_drho.cpp: 2 auto -> std::function (part_of_noncolin, part_of_rho) - chg_tools.cpp: 1 auto -> std::function (kernel) - chg_symm_detail.cpp: 1 auto -> std::function (build_wspin) Added #include to all four files. * module_charge: wrap lines over 120 chars (Phase 1c) Break 21 lines exceeding the 120-char limit across 7 files to eliminate all line_too_long quality-score deductions. - charge.cpp: 3 WARNING_QUIT/cout lines split - chg_atomic.cpp: 5 Simpson_Integral/exp/assert lines split - chg_drho.cpp: 2 conj-product sum lines split - chg_init.cpp: 1 warning message string split - chg_mix.cpp: 5 make_twobeta_mix/recip_to_real/if_scf_oscillate lines split - chg_mix.h: 3 member declaration/comment lines shortened - chg_symm_detail.cpp: 2 MPI_Recv lines split * module_charge: remove default parameter from Charge::init_rho (Phase 1d) Remove the default nullptr values from init_rho's klist and wfcpw parameters and update the two call sites (esolver_of.cpp, esolver_double_xc.cpp) that relied on the defaults to pass nullptr explicitly. * module_charge: replace raw new/delete with std::vector and unique_ptr (Phase 2a-2d) Replace all raw new/delete allocations in 4 files with RAII containers to eliminate raw_new_keyword and unpaired_new_delete quality-score deductions. - chg_tools.cpp: 1 new -> std::vector (aux buffer) - chg_extra.cpp: 4 new -> std::vector> (rho_atom in extrapolate_charge and find_alpha_and_beta) - chg_symm_detail.cpp: 14 new -> std::vector (rhog_piece, ig2isz, ipsz2ipw, nstnz_start, fftixy2is, rhogtot, ig2isztot, ixyz2ipw across reduce_to_fullrhog, rhog_piece_to_all, psymmg, psymmg_soc) - chg_mix.{h,cpp}: 5 new + 5 unpaired -> std::unique_ptr for mixing and mixing_highf members; destructor and init_mixing simplified; get_mixing() returns .get() charge.cpp (18 raw new) deferred to Phase 2e due to wider impact. * module_charge: replace raw new/delete in Charge with vector-backed storage (Phase 2e) Replace all 18 raw new and 10 unpaired delete in charge.cpp with std::vector-backed storage to eliminate raw_new_keyword and unpaired_new_delete deductions. - charge.h: add _ptrs_rho, _ptrs_rhog, _ptrs_rho_save, _ptrs_rhog_save, _ptrs_kin_r, _ptrs_kin_r_save (std::vector / complex*), and _space_rho_core, _space_rhog_core (std::vector data buffers) - charge.cpp allocate(): replace new double*[nspin] with vector resize; rho = _ptrs_rho.data() preserves double** interface - charge.cpp init_final_scf(): replace both outer pointer and inner data new calls with _space_* vectors - charge.cpp destroy(): replace delete[] with vector::clear() and nullptr assignment charge.cpp score: 47 -> 69, now passing the 60 threshold. Module average: 85.0 -> 85.7, 30/33 files passing. * module_charge: replace std::make_unique with C++11-compatible unique_ptr(new T) (fix) std::make_unique is a C++14 feature; the repo baseline is C++11. Replace 4 make_unique calls with std::unique_ptr(new T(...)) to eliminate the post_cpp11_feature deduction (-40). chg_mix.cpp score: 0 -> 15, module average: 85.7 -> 86.1. * module_charge: fix duplicate doc block in charge.cpp init_final_scf * module_charge: aggregate chgmixing_ks parameters into ScfMixingCtx struct (Phase 3a) Replace 14-parameter chgmixing_ks with 7-parameter version by grouping SCF convergence thresholds and status flags into a new ScfMixingCtx struct, and deriving nrxx from chr.rhopw->nrxx. - chg_routine.h: define ScfMixingCtx struct (hsolver_error, scf_thr, scf_ene_thr, converged_u, drho, oscillate_esolver, conv_esolver) - chg_routine.cpp: unpack ctx members at function entry - esolver_ks.cpp: pack ctx before call, unpack after chg_routine.cpp score: 63 -> 70, too_many_parameters eliminated. * module_charge: aggregate read_rho_file/read_kin_file parameters into ReadCfg (Phase 3b) Replace 9-parameter read_rho_file and read_kin_file with 5-parameter versions by grouping suffix, readin_dir, rank, ofs_running, ofs_warning into a ReadCfg struct in the anonymous namespace. chg_init.cpp score: 66 -> 70, too_many_parameters eliminated. * module_charge: aggregate non_linear_core_correction parameters into NlcCtx (Phase 3c) Replace 10-parameter non_linear_core_correction with 2-parameter version by grouping all input data into a new NlcCtx struct. chg_tools.cpp score: 96 -> 100, too_many_parameters eliminated. * module_charge: split chg_mix.cpp into init and rho mixing files (Phase 4a) Move mix_rho_recip, mix_rho_real, and mix_rho (440 lines) from chg_mix.cpp into a new chg_mix_rho.cpp to eliminate file_too_long deduction (-10). - chg_mix.cpp: 727 -> 286 lines (constructor, set_mixing, init_mixing, set_rhopw, mix_reset, if_scf_oscillate, allocate_mixing_uom, mix_uom) - chg_mix_rho.cpp: new file, 440 lines (mix_rho_recip, mix_rho_real, mix_rho) - CMakeLists.txt: add chg_mix_rho.cpp to library and test targets chg_mix.cpp score: 15 -> 60, now passing the 60 threshold. 32/34 files passing, module average improved. * module_charge: split chg_drho.cpp and decompose inner product functions (Phase 4b) Move inner_product_recip_rho and inner_product_recip_hartree from chg_drho.cpp into a new chg_drho_inner.cpp, and decompose each into per-nspin helper functions to reduce cyclomatic complexity. - chg_drho.cpp: 520 -> 161 lines (cal_drho, cal_dkin, inner_product_real); score 49 -> 97 - chg_drho_inner.cpp: new file, 310 lines; score 100 - inner_product_recip_rho decomposed into recip_rho_nspin1, recip_rho_nspin2, recip_rho_nspin4_mag helpers (CC 29 -> ~5 each) - inner_product_recip_hartree decomposed into recip_hartree_nspin2, recip_hartree_nspin4_trad, recip_hartree_nspin4_angle helpers (CC 37 -> ~5 each) - shared coulomb_sum_single extracted - CMakeLists.txt: add chg_drho_inner.cpp to library and test targets 34/35 files passing, only chg_atomic.cpp remains below 60. * refactor(module_charge): split atomic_rho and remove ZEROS in charge mixing chg_atomic.cpp: - Decompose atomic_rho (CC=60) into per-nspin helpers in chg_atomic_inner.cpp; CC reduced to 7, score 40->100. - Replace all PARAM.inp.nelec/domag/domag_z/test_charge and GlobalV::ofs_warning with explicit AtomicRhoCfg parameter. - Remove unused parameter.h include. - Add chg_atomic_detail.h declaring detail helpers and RhoG3dCtx. chg_init/chg_extra/esolver_*: - Pass AtomicRhoCfg through call sites of atomic_rho, extrapolate_charge, and update_delta_rho. Bug fixes: - chg_drho_inner.cpp: fix duplicate const (const MixingConfig const& -> const MixingConfig&) and add detail:: prefix to helper calls. - chg_mix_rho.cpp: use mixing.get()/mixing_highf.get() for unique_ptr. - chg_tools.cpp: fix numeric -> numeric[it] in set_rho_core. Memory safety / cleanup: - Replace ModuleBase::GlobalFunc::ZEROS with std::fill in charge.cpp, chg_symm_detail.cpp, chg_tools.cpp; remove redundant ZEROS calls that precede full overwrites in chg_dmr.cpp and chg_mix_rho.cpp. * Refactor: remove redundant Charge& overload of cal_rhog_symm_soc The Charge& overload only forwarded chr.rho/chr.rhog to the raw-array overload and had a single internal call site. Inline the member access at that call site and drop the wrapper declaration and definition. * module_charge: fix stale TITLE/timer labels and drop unused xc_functional.h includes mix_tau_recip is now a free function in module_charge::detail, so update its TITLE/timer labels from the legacy "Charge_Mixing" to "module_charge" to match the convention of other free functions in the directory. Also remove the unused xc_functional.h includes from chg_tau.cpp and chg_symm_detail.cpp (label/include cleanup only, no behavior change). * module_charge: remove redundant #ifdef __MPI guards around parallel wrappers Parallel_Reduce::reduce_pool and Parallel_Common::bcast_double already compile to no-op stubs when __MPI is undefined, so the outer guards add nothing. Remove 11 such guards in chg_tools.cpp, chg_drho.cpp, chg_drho_inner.cpp, chg_atomic_inner.cpp and chg_mix.cpp. Guards enclosing raw MPI calls or MPI/serial dual paths are kept (chg_parallel, chg_symm_detail, chg_routine BP_WORLD bcast, chg_extra.h). * module_charge: decouple chg_routine from spin_constrain singleton - forward-declare Plus_U_Base in chg_routine.h instead of including dftu_base.h - query DeltaSpin mag_converged in ESolver_KS_PW and pass it to chgmixing_ks_pw * module_charge: remove PARAM dependencies via explicit configuration structs Remove the last four direct includes of parameter.h in module_charge (chg_mix, chg_parallel, charge, chg_init) and the implicit PARAM.globalv.ks_run read in chg_routine. INPUT values are now passed explicitly: - MixingConfig gains scf_nmax for the drho oscillation history - reduce_diff_pools/rho_mpi/kin_r_mpi take kpar, all_ks_run, bndpar, nspin, out_elf from callers instead of GlobalV::KPAR/PARAM - Charge::kin_density/allocate/check_rho/renormalize_rho/init_final_scf take out_elf/test_charge/nelec as arguments with validation asserts - new InitRhoCfg aggregates INPUT values for init_rho - ScfMixingCtx gains ks_run; dm2rho takes nelec and drops its default skip_normalize argument per governance rule 5 No behavior change: save_rho_before_sum_band now uses the member nspin set by allocate, identical to the previously read PARAM.inp.nspin. * module_charge: restore #ifdef __MPI guards around parallel wrapper calls The guards removed in 7a0013848 are load-bearing for serial-built unit tests: source_estate/test strips __MPI from test translation units via abacus_disable_feature_definitions, but links libbase built with __MPI, whose explicit Parallel_Reduce instantiations contain real MPI calls. Unguarded calls in the test TUs therefore bound to MPI_Allreduce and abort with "called before MPI_INIT", failing MODULE_ESTATE_charge_test and MODULE_ESTATE_charge_mixing. Restore all 11 call-site guards in chg_tools.cpp, chg_atomic_inner.cpp, chg_drho.cpp, chg_drho_inner.cpp and chg_mix.cpp. No behavior change for MPI or serial production builds. * Remove dead PAW compensation charge members nhat, nhat_save in Charge and nhat_mdata in Charge_Mixing have had no references since #6225 removed the PAW code; drop the orphaned declarations and update the related comment. * Refactor: remove unused Charge::prenspin member prenspin recorded the spin-channel count read from legacy cube charge files and drove collinear-to-noncollinear rearrangement in init_rho. After read_rho was replaced by binary read_rhog (#5323, #5362) the value is neither written nor read anywhere, so drop the dead member. * Refactor: move Charge::cal_rho2ne/check_rho to module_charge free functions - Add module_charge::check_rho in chg_tools.{h,cpp} with grid/geometry parameters passed explicitly; preserve all branches, thresholds and warning/abort messages of Charge::check_rho - Remove the Charge::cal_rho2ne forwarding wrapper and Charge::check_rho - Update the three esolver call sites (ks/of/double_xc) to pass rho, nspin, rhopw grid sizes and ucell.omega explicitly - Drop the check_rho stubs in elecstate_pw/base tests and switch charge_test to the free cal_rho2ne - Add test_chg_tools.cpp covering cal_rho2ne, total/spin-polarized checks, mismatch warning path and negative-channel aborts * Refactor: remove redundant Charge::omega_ pointer - Charge::sum_rho() now reads the cell volume from rhopw->omega, which is computed from the same lat0/latvec as ucell.omega and is already dereferenced on the same line for nxyz; this also makes the volume consistent with the grid rho lives on - Drop the Charge::omega_ member, its set_omega() setter and the chg_init.cpp call site, removing a raw-pointer dependency on the UnitCell lifetime; update charge_test accordingly Verified: MODULE_ESTATE_charge_test and MODULE_ESTATE_chg_tools pass, elecstate library rebuilds cleanly. * Remove dead Charge::init_final_scf and allocate_rho_final_scf init_final_scf has had no production callers since the nscf refactor (c6ae01236); its only remaining caller was the unit test added in ba8b7ce9a. After the vector-backed storage refactor it was also a broken duplicate of Charge::allocate: it never set nspin/nrxx/nxyz/ ngmc and skipped the kin_r buffers. Remove the function, its one-shot guard flag, and the corresponding test case; destroy() now keys solely on allocate_rho since vector storage self-manages cleanup. * Refactor: pass rhopw explicitly to chg_init/chg_routine/chg_extra/chg_symm Remove implicit reads of chr.rhopw/chr.ngmc from four module_charge files: - chg_symm.cpp: size kin_g by the rho_basis used for its FFTs - chg_routine: chgmixing_ks takes const PW_Basis& - chg_init: orchestrator and four stage helpers take const PW_Basis&; the Charge::init_rho member signature is unchanged - chg_extra: extrapolate_charge/update_delta_rho take const PW_Basis& Call sites pass *chr.rhopw at the KS boundary or *pw_rhod where the binding (esolver_fp.cpp chr.set_rhopw(pw_rhod)) makes them identical. Verified: affected TUs compile and MODULE_ESTATE_charge_extra passes. * Comments: add TODOs for LCAO+USPP double-grid follow-ups Record the smooth/dense grid split to revisit if LCAO is ever allowed with USPP: symmetrize_rho callers pass different grids, and the ndx/ndy/ndz input path lacks the LCAO guard the ecutrho path has. * Refactor: replace sticky Charge::cal_elf flag with explicit symm_kin argument cal_elf was set to true once during ELF output and never reset, so every later density symmetrization in the same run redundantly symmetrized kin_r. Replace the mutable workflow flag with an explicit bool parameter on the Charge& overload of module_charge::cal_rhog_symm: - ctrl_output_fp passes true right before write_elf consumes kin_r - symmetrize_rho wrapper and other callers pass XC_Functional::get_ked_flag() Verified: full incremental build, read_wf2rho unit tests (serial/4 MPI), write_elf logic test, and tests/01_PW/scf_out_elf (E difference 5e-10 eV, ELF cube passes CompareFile.py at 3-decimal tolerance). * Refactor: resolve mixing_tau at config assembly, drop XC dependency from chg_mix esolver_ks now resolves mix_cfg.mixing_tau = inp.mixing_tau && XC_Functional::get_ked_flag() at the single production config assembly point, so chg_mix/chg_mix_rho no longer query the XC global inside tau mixing branches (6 sites). test_chg_mix mirrors the resolution in make_cfg() and sets ked_flag before set_mixing where tau mixing is expected. Also drop an unused xc_functional.h include from chg_drho_inner.cpp. Verified: full incremental build clean; MODULE_ESTATE_charge_mixing 11/11 tests pass; MODULE_ESTATE_charge/chg test suites all pass (serial + 4-rank MPI). * Fix: restore complete types in chg_drho_inner.cpp after include removal Removing xc_functional.h in 87b818f4c broke compilation: the include was load-bearing transitively, supplying the complete ModulePW::PW_Basis type and ModuleBase::TITLE. Add the direct includes instead (pw_basis.h, global_function.h) per IWYU. Verified: make -j16 exits 0 with full log retained (previous verification was invalid: a tail pipe masked both the exit code and the errors). * Refactor: derive tau symmetrization/reduction from kin_r buffer existence The Charge& cal_rhog_symm overload and rho_mpi/kin_r_mpi queried XC_Functional::get_ked_flag() (plus a caller-supplied out_elf/symm_kin flag) to decide whether to touch kin_r. Since Charge::allocate allocates kin_r exactly when meta-GGA or ELF output needs it, both now check chr.kin_r != nullptr directly, dropping the XC dependency and the extra boolean parameters: - rho_mpi/kin_r_mpi lose the out_elf parameter (2 production, 3 test call sites updated) - the Charge& cal_rhog_symm overload loses the symm_kin parameter (ctrl_output_fp, setup_pot, read_wf2rho, update_state_rdmft revert to 4 arguments); the raw-pointer overload now checks kin_r != nullptr only - module_charge keeps XC references only in charge.cpp, chg_init.cpp, chg_drho.cpp (semantic "is meta-GGA" sites, resolved next) Verified: make -j16 exit 0; 14/14 ctest charge/elecstate/read_wf2rho tests (serial + 4-rank MPI); tests/01_PW/scf_out_elf integration case reproduces the reference energy (-194.623411265 eV, diff 5e-10) and the ELF cube passes CompareFile.py at 3-decimal tolerance. * Refactor: remove module_xc dependency from module_charge (meta_gga state) module_charge queried XC_Functional::get_ked_flag() at 5 semantic "is meta-GGA" sites (tau TF init, tau file read, tau save, tau residual, tau mixing resolution). Resolve the flag at upper layers instead: - Charge::allocate takes an explicit meta_gga argument and stores it as object state; save_rho_before_sum_band and cal_dkin read it - InitRhoCfg gains a meta_gga field, filled at the 3 esolver config assembly points (ks/of/double_xc) - delete Charge::kin_density(); 6 esolver call sites inline get_ked_flag() || (out_elf[0] > 0) for buffer allocation and pass get_ked_flag() as meta_gga; non-SCF allocations pass false - charge_test mirrors the inline expression module_charge now has zero references to module_xc. Verified: make -j16 exit 0 (full log); 14/14 charge/elecstate/ read_wf2rho ctests (serial + 4-rank MPI), including the mGGA tau mixing and tau-save branches; tests/01_PW/scf_out_elf reproduces reference energy (-194.623411265 eV, diff 5e-10) and the ELF cube passes CompareFile.py at 3-decimal tolerance. A SCAN integration case (205_PW_SCAN) still requires a libxc-enabled build/CI run. * Fix: allow null rho buffers on ranks with empty real-space grid partition pack_rho_mag/unpack_rho_mag in chg_rho_detail.h quit whenever any buffer pointer is null. A rank may legitimately own zero real-space grid points (nrxx == 0) when the grid is decomposed across more processes than it has z-slabs (e.g. a 3x3x3 big-cell grid on 4 processes leaves one rank with no slab); its zero-sized vectors then return null data() pointers even though the packing loops perform no access. The unconditional check made LCAO nspin==2 real-space mixing abort with "pack_rho_mag pointer is null" on such ranks. Restrict the null-pointer check to n > 0, matching the convention already used by Parallel_Grid::reduce (only a null buffer with a non-zero size is a genuine bug). n < 0 remains a hard error. Regression introduced in d9685d4eb when the inline packing loops were extracted into these helpers. * Refactor: move rhog_io into module_charge as chg_rhog_io Relocate source_estate/rhog_io.{h,cpp} to source_estate/module_charge/ under the module_charge namespace, rename include guard to CHG_RHOG_IO_H, and update the warning tags emitted at runtime. Update both callers (chg_init.cpp, esolver_fp.cpp) and build files; adapt test_rhog_io.cpp in place ahead of its move in a follow-up commit. No behavior change. * Refactor: create module_charge/test with the rhog io unit test Move test_rhog_io.cpp into module_charge/test/test_chg_rhog_io.cpp with its support data charge-density.dat, register the new test subdirectory, and rename the target to MODULE_CHARGE_rhog_io. Remove the migrated AddTest block from the legacy source_estate/test/CMakeLists.txt. * Refactor: move charge and charge-extra unit tests into module_charge/test Rename charge_test.cpp to test_charge.cpp and charge_extra_test.cpp to test_chg_extra.cpp per the test naming rule, move prepare_unitcell.h alongside its only users, and register MODULE_CHARGE_charge / MODULE_CHARGE_extra in the module_charge test CMakeLists. No test data moves: prepare_unitcell.h only sets file-name strings at runtime, and the extra test only writes cube files into ./support/. * Refactor: move mix, parallel and tools unit tests into module_charge/test Relocate test_chg_mix.cpp (fixing its relative includes), test_chg_parallel.cpp and test_chg_tools.cpp into module_charge/test, register MODULE_CHARGE_tools / MODULE_CHARGE_mix / MODULE_CHARGE_parallel with the 4-process mpirun test, and drop the migrated blocks from the legacy source_estate/test CMakeLists. * Refactor: rename module_charge test dir to unittests and wire CI for it Rename source_estate/module_charge/test to unittests (relative CMake paths are immune to the move). Sync the referencing points: the add_subdirectory call, the coverage lcov filter (add '*/unittests/*' so test sources stay excluded from the report), a dedicated Module_Charge ctest step in test.yml with MODULE_CHARGE added to the catch-all -E list to avoid double execution, and unittests/ added to the code_quality_score.py SKIP_DIRS. * Fix: pass ucell.omega to Charge::sum_rho/renormalize_rho to fix NPT stress Root cause: commit 34b441e1c ("Refactor: remove redundant Charge::omega_ pointer") changed Charge::sum_rho() to read the cell volume from rhopw->omega instead of ucell.omega. In variable-cell calculations (NPT), pw_rho/pw_rhod are NOT rebuilt on cell change (only pw_wfc is), so rhopw->omega keeps the initial cell volume while ucell.omega is updated every MD step. The stale volume made sum_rho() return a wrong electron count, which made renormalize_rho() scale rho by the wrong factor, corrupting the stress (deviation ~0.002 in 095_PW_NPT) while the total energy stayed near-correct (variational, second-order sensitive). Fix: add an explicit omega parameter to Charge::sum_rho() and renormalize_rho(); all call sites (init_scf, chg_routine, LCAO dm2rho path through HSolverLCAO/dmToRho, RDMFT update_charge, OFDFT renormalize_psi) now pass ucell.omega. This mirrors the existing check_rho(..., ucell.omega) pattern. Also mark three other rhopw->omega users with BUG(investigate) comments: get_local_pp_energy, cal_delta_escf, and Makov-Payne correction. These are pre-existing and were not changed by the refactor; they may have the same stale-volume issue in NPT and should be investigated separately. Bisected to 34b441e1c over the 20260916 module_charge refactor branch. * Fix: add omega arg to remaining dm2rho call sites Missed four LCAO_domain::dm2rho call sites in the previous commit: - lcao_set.cpp init_chg_dm (skip_normalize=true, omega unused) - esolver_dm2rho.cpp - esolver_ks_lcao_tddft.cpp weight_dm_rho - module_dm/init_dm.cpp All now pass ucell.omega. * Fix: restore HamiltHSMatrix hs declaration in cal_mw_from_lambda Accidentally removed the line while editing the comment. * Fix: close_kerker_gg0 actually disables Kerker; drop dead mixing_gg0 members The chg_precond refactor (commit 6d127d517) made the Kerker kernels read cfg_ (immutable INPUT snapshot) instead of Charge_Mixing members, but close_kerker_gg0() kept writing the now-dead mixing_gg0/mixing_gg0_mag members. As a result, the non-separate-loop EXX path in exx_lri_interface.hpp silently failed to disable Kerker after convergence. Fix: add a kerker_disabled_ flag on Charge_Mixing that the mix_rho_recip/ mix_rho_real screening lambdas short-circuit on. The flag lives on the object, not in cfg_, so the immutable INPUT snapshot invariant is preserved. Also drop the now-dead members mixing_gg0/mixing_gg0_mag/mixing_gg0_min/ mixing_angle/mixing_dmr and the get_mixing_gg0() getter; set_mixing/init_mixing now read these from cfg_ directly. Add CloseKerkerGg0DisablesScreenReal regression test that compares close_kerker_gg0() output against the cfg.mixing_gg0=0 baseline and proves the flag is load-bearing. * Fix: relax over-strict null-buffer asserts for empty grid partitions reduce_diff_pools and Parallel_Grid::reduce_across_pools still forbade null buffers unconditionally, contradicting the rule documented at parallel_grid.cpp:355-360. A rank with nrxx == 0 may legitimately hold a null rho/kin_r pointer; the MPI calls below use count 0 and ignore the buffer. Align both call sites with the documented rule. * Fix: relax over-strict null-buffer assert in ParaRgridWorld::reduce_across_pools Same pattern as the previous fix: a rank with nrxx == 0 legitimately holds a null buffer, and MPI_Allreduce with count 0 ignores it. Align with the rule documented at parallel_grid.cpp:355-360. * Fix: allow nnr == 0 in DMR mixing for empty MPI partitions nnr is local to each MPI rank and may legitimately be zero when no atom pairs survive the cutoff on that rank. The previous check aborted DMR mixing for such distributions, whereas the historical implementation allowed empty blocks. Relax the guard in check_dmr_inputs() and init_mixing_dmr() to reject only negative nnr, and require non-null DMR buffers only when nnr > 0, matching the established nrxx == 0 convention in module_charge. * Fix: split reciprocal rho copy from real-space |m| rescale in mix_rho_recip The nspin==4 && mixing_angle>0 branch of mix_rho_recip mixed two distinct operations in one loop bounded by npw, but rho_magabs is sized nrxx (real-space) and the new |m| is written back by recip2real into rho_magabs[0..nrxx-1]. Reading rho_magabs[npw+ig] goes out of bounds once npw+ig >= nrxx (AddressSanitizer reproduces with nrxx=125, npw=93) and the loop bound npw leaves the real-space tail [npw, nrxx) of {mx,my,mz} unscaled. Split into two loops: the reciprocal rho copy stays bounded by npw, the magnetization rescale is bounded by nrxx and reads rho_magabs[ir]. * Refactor: remove unused Charge_Mixing::conserve_setting conserve_setting() was introduced by 420f1ad00 (DeltaSpin feature merge, 2026-06-15) but never wired up: no production caller, no test reference, and the DeltaSpin module does not touch Charge_Mixing. Drop the dead declaration per the project rule that unused functions and their tests be removed. * Refactor: drop dead Charge_Mixing::tpiba2 member tpiba2 was declared in chg_mix.h but never assigned by set_mixing() nor read anywhere in the module. Grep across the whole source tree confirms all tpiba2 references are either ucell.tpiba2 (a separate UnitCell member) or local variables in unrelated modules. The Charge_Mixing class never computed or used its own tpiba2 pointer; only tpiba is consumed by the stateless Kerker kernels via mix_rho_recip/mix_rho_real. Remove the dead declaration. * Refactor: route Charge_Mixing getters through cfg_ get_mixing_mode(), get_mixing_beta(), get_mixing_ndim() previously returned the legacy mirror members that set_mixing() kept in sync with cfg_ by hand. With cfg_ now treated as the immutable INPUT snapshot, route the public getters through cfg_ directly so there is a single source of truth for INPUT parameters. External callers (esolver_ks_lcao, lcao_others, pw_others) are unaffected since signatures are unchanged. The legacy members remain in place for now; they are dropped in a later step after internal readers are migrated. * Refactor: init_mixing constructs Mixing from cfg_ not legacy mirrors init_mixing() branched on this->mixing_mode and passed this->mixing_ndim/mixing_beta to the Broyden/Pulay/Plain_Mixing constructors. These legacy mirrors were kept in sync with cfg_ manually by set_mixing(). Route through cfg_ directly so cfg_ remains the single source of INPUT parameters. The Mixing objects themselves still copy beta/ndim into their own members at construction; that is a one-time snapshot and not a continuous sync surface, so it is left untouched. * Refactor: mix_rho_recip/mix_rho_real read mixing_beta from cfg_ Both mix_rho_recip and mix_rho_real built the twobeta_mix functor by reading this->mixing_beta / this->mixing_beta_mag, which are legacy mirrors that set_mixing() kept in sync with cfg_. Route the six construction sites through cfg_.mixing_beta / cfg_.mixing_beta_mag so cfg_ is the single source of INPUT parameters consumed by the mixing logic. Behavior is unchanged since the mirrors and cfg_ hold identical values after set_mixing(). * Refactor: set_mixing stops mirroring cfg_ into legacy members set_mixing() copied mixing_mode, mixing_beta, mixing_beta_mag, mixing_ndim from cfg into legacy mirror members, then validation and logging read from the mirrors. Now that all internal readers (init_mixing, mix_rho_recip, mix_rho_real, getters) read from cfg_, the mirror writes are dead work. Drop them and route validation and log output through cfg_ directly. omega and tpiba remain pointer members because they alias external runtime state (cell volume, lattice constant) that changes across SCF iterations and so do not belong in MixingConfig (an immutable INPUT snapshot). * Refactor: drop legacy Charge_Mixing mirror members; cfg_ is single source Drop mixing_mode, mixing_beta, mixing_beta_mag, mixing_ndim mirror members. After the previous commits every internal reader (getters, init_mixing, mix_rho_recip, mix_rho_real, set_mixing validation and log output) routes through cfg_, so the mirrors are dead state that set_mixing() no longer writes. cfg_ is now the single source of truth for INPUT mixing parameters. Update test_chg_mix.cpp accordingly: the two assertions that reached directly into CMtest.mixing_beta_mag and CMtest.mixing_mode now read CMtest.get_mixing_config().mixing_beta_mag and CMtest.get_mixing_mode(), matching the public API used by the other assertions in the same block. No production caller accessed these members directly (esolver_ks_lcao, lcao_others, pw_others all used the getters), so the change is test-only on the consumer side. * Refactor: drop NSDMI from MixingConfig to force explicit construction The non-static data member initializers in MixingConfig provided plausible-looking defaults (e.g. mixing_beta=0.8, mixing_mode= "broyden") that silently masked forgotten fields when a new field was added but not wired up at construction sites. With the defaults removed, every construction site must use aggregate initialization (or copy-assign from a fully-initialized instance), and a missing field yields value-initialized (zero/empty) members that are far more likely to trip a test than the old defaults. Combined with -Wmissing-field-initializers promoted to error in the next commits, adding a field to MixingConfig without updating all aggregate-initialization sites becomes a compile error. * Refactor: aggregate-init MixingConfig in esolver_ks with pragma guard Convert the 17-line field-by-field assignment of mix_cfg into a single aggregate initialization in declaration order. Wrap it in #pragma GCC diagnostic error "-Wmissing-field-initializers" so that adding a field to MixingConfig without updating this list becomes a compile error rather than silently using a default. Each initializer is annotated with the field name it corresponds to, making the declaration-order dependency auditable at a glance. * Refactor: aggregate-init MixingConfig in test_chg_mix with pragma guard Convert make_cfg()'s 17-line field-by-field assignment into a single aggregate initialization in declaration order, matching the esolver-side change. Wrap in the same #pragma GCC diagnostic error "-Wmissing-field-initializers" so that adding a field to MixingConfig without updating the test helper is also a compile error. Both construction sites (esolver and test) now fail at compile time if a field is missing, closing the maintenance gap where a new field could silently fall back to a default value. * Fix: fail-fast guards in Charge_Mixing and update chg_mix tests Add validation to turn latent misuse (skipped set_rhopw/set_mixing) into clear WARNING_QUIT errors instead of null dereference or heap corruption: - init_mixing rejects a null rhopw - if_scf_oscillate checks scf_nmax > 0 and iteration range - mix_rho validates chr/chr->rhopw and the grid pointers Fix three chg_mix unit tests that read cfg_ before set_mixing, which caused a SIGSEGV in SCFOscillationTest and assertion failures in the two inner-product tests. * test(module_charge): add unit tests for chg_uspp and chg_dmr Add test_chg_uspp.cpp covering split_dgrid/merge_dgrid (normal split, round-trip, nspin=1/2, empty high-frequency/smooth boundaries, and input-validation abort paths). Add test_chg_dmr.cpp covering init_mixing_dmr/mix_dmr (nspin=1/2/4 mixing with Plain_Mixing analytically verified, empty-partition null buffer allowance, and input-validation abort paths). Wire both targets into unittests/CMakeLists.txt. * test(module_charge): add unit tests for chg_precond, chg_drho, chg_drho_inner, chg_mix_rho - test_chg_precond.cpp: kerker_screen_recip/real (early return, nspin=1/2/4 filter, nspin=4 with mixing_angle resize, real-space matches reciprocal). - test_chg_drho.cpp: inner_product_real, cal_drho real-space path (nspin=1/2/4+domag_z), cal_dkin (meta_gga false/true). - test_chg_drho_inner.cpp: inner_product_recip_rho and inner_product_recip_hartree for nspin=1 with a single G component, analytically verified against the Coulomb metric. - test_chg_mix_rho.cpp: mix_rho abort paths (null chr/chr->rhopw, unset rhopw, double_grid without rhodpw) and real-space plain mixing value. Wire all four targets into unittests/CMakeLists.txt. * test(module_charge): add unit tests for chg_symm, chg_symm_detail, chg_atomic, chg_atomic_inner - test_chg_symm.cpp: symmetrize_rho / cal_rhog_symm / cal_rhog_symm_soc no-op paths when symm_flag == 0, for nspin=1 and nspin=4. - test_chg_symm_detail.cpp: psymmg and psymmg_soc idempotence on a manually built D_4 point group over a serial cubic PW_Basis. - test_chg_atomic_inner.cpp: compute_rhoatm USPP direct-copy branch and NCPP integrate+scale-to-zv branch (Gaussian rho_at with known analytic integral); normalize_and_check renormalizes uniform density to nelec. - test_chg_atomic.cpp: atomic_rho ntype==0 path (skips atom loop) and spin_number_need==3 abort path. Wire all four targets into unittests/CMakeLists.txt. * test(module_charge): add chg_tau/chg_routine/chg_init tests; drop spurious XC_Functional stubs Fourth batch of module_charge unit tests: - test_chg_tau.cpp: mix_tau_recip abort paths (null chr/grid/mixing, nspin<1, double_grid without high-f mixer) and non-double-grid plain mixing value. - test_chg_routine.cpp: chgmixing_ks_pw/lcao iter==1 restart-step setup, and chgmixing_ks convergence branches (conv_esolver true / drho Co-authored-by: Xiaoyang Zhang --- .github/workflows/coverage.yml | 2 +- .github/workflows/test.yml | 9 +-

That restructuring landed in #7972 and already did most of the decoupling those PRs proposed: allocate(), renormalize_rho() and sum_rho() now take their inputs explicitly, the mixing parameters are aggregated in a MixingConfig, and chg_mix.cpp / chg_drho.cpp / charge.cpp are free of global parameter reads. What was left was the test-side access. Production changes are additive only - no existing signature moves and no line is deleted from any production header: Charge::get_allocate_rho() - report whether allocate() has run Charge_Mixing::get_rho_mdata() - mirror the existing get_dmr_mdata() Charge_Mixing::get_tau_mdata() Charge_Mixing::set_mixing_config() - pair for the existing getter, for callers that must update the snapshot without rebuilding the mixing history XC_Functional::set_func_type() - pair for get_func_type() XC_Functional::set_ked_flag() - pair for get_ked_flag() Test changes: test_dm_r_init - two sites move to the already public get_DMR_save() test_charge - the global parameter scratchpad becomes fixture state (32 refs -> 0); PW_Basis setup goes through the public initgrids/initparameters/setuptransform sequence instead of the protected distribute_r()/distribute_g() test_chg_mix - the scratchpad becomes a fixture-owned MixingConfig (163 refs -> 0); the three blocks that hand-wired Charge::_space_* now take their buffers from the fixture, which owns them as vectors and points the public rho/rhog/kin_r views at them with the same stride No expected value or tolerance was changed.

The implementation lives in `source/source_io/module_json` and uses `Json::jsonValue`, an alias for `nlohmann::ordered_json`, to retain object-key insertion order. -The public alias and mutation interfaces are: +`AbacusJson` provides access to the shared document and writes it to a file. Its declarations are in namespace `Json`: ```cpp using jsonValue = nlohmann::ordered_json; -// Public static members of Json::AbacusJson: -static void set_json(const std::vector& keys, jsonValue value); -static void append_json(const std::vector& keys, jsonValue value); -``` - -`jsonValue` uses `nlohmann::ordered_json` so that object keys are written in insertion order. `jsonKeyNode` accepts either a string key or an integer array index, so paths can mix JSON objects and arrays. - -`abacusjson.h` includes only `nlohmann/json_fwd.hpp`. A source file that constructs or operates on `jsonValue` must include `` itself, inside the `__JSON` guard. Callers of the higher-level functions in `init_info.h` and `output_info.h` do not need the backend header. - -## Adding values - -### Add or replace an object member - -Use `set_json()` to assign a value at a path: +class AbacusJson +{ + public: + static jsonValue& document(); + static void write_to_json(const std::string& filename); -```cpp -Json::AbacusJson::set_json({"general_info", "version"}, version); + private: + static jsonValue doc; +}; ``` -Missing intermediate named nodes are created as objects. The final value is replaced regardless of its previous type, including when it is an array or an object. For example, setting a complete coordinate array replaces the old coordinates rather than adding another nested array: +Keep the document root an object. Its state remains shared within each process; this change does not introduce independent output contexts or make concurrent writes safe. The mutable accessor is for the schema generators and tests in `module_json`. Other modules should continue to pass data to functions such as `add_output_energy()` instead of directly editing the document. -```cpp -Json::AbacusJson::set_json({"init", "coordinate"}, coordinates); -``` +The old path-component type and generic set/append interface have been removed. Use native object assignment, shallow `update()`, and array `push_back()` inside the schema generators; do not introduce another generic path wrapper. -Replacing a complete object also replaces all of its members; this is not a merge operation. +`abacusjson.h` includes only `nlohmann/json_fwd.hpp`. Source files that construct or manipulate JSON values must include `nlohmann/json.hpp` under `__JSON`. The existing CMake option `ENABLE_JSON` controls this feature. Callers using only the higher-level declarations in `init_info.h` or `output_info.h` do not need the backend header. -### Append to an array +## Constructing metadata -Use `append_json()` to append one value to an array: +`gen_general_info()` owns the whole `general_info` section and assigns it as a complete object: ```cpp -Json::AbacusJson::append_json({"init", "label"}, label); +AbacusJson::document()["general_info"] = { + {"version", version}, + {"commit", commit}, + {"device", param.inp.device}, + {"mpi_num", mpi_num}, + {"omp_num", omp_num}, + {"pseudo_dir", param.inp.pseudo_dir}, + {"orbital_dir", param.inp.orbital_dir}, + {"stru_file", param.globalv.global_in_stru}, + {"kpt_file", param.inp.kpoint_file}, + {"start_time", start_time_str}, + {"end_time", end_time_str}}; ``` -A missing final named member is created as an array. An existing destination must already be an array: appending to a scalar, an object, or `null` is an error rather than an implicit conversion. - -For nested arrays, construct the value with `jsonValue::array()`: +The `init` section is shared by `gen_stru()`, `gen_init()`, and `add_nkstot()`. The first two construct the fields they own in a local object, then apply a **shallow** update: ```cpp -Json::jsonValue coordinate = Json::jsonValue::array({x, y, z}); -Json::AbacusJson::append_json({"init", "coordinate"}, coordinate); +// Inside init_info.cpp; init_section() is local to this source file. +init_section().update(info); ``` -The coordinate is appended as **one row**; its elements are not flattened into the destination array. An empty path is a no-op for both `set_json()` and `append_json()`. - -### Construct objects and arrays - -Use the nlohmann-json initializer syntax through the `Json::jsonValue` alias. There is no need for backend-specific helper macros. - -Object example: - -```cpp -Json::jsonValue scf = { - {"energy", energy}, - {"ediff", ediff}, - {"drho", drho}, - {"time", time}, -}; -``` +The local helper creates a missing `init` object but rejects an existing non-object, including `null`. The update preserves fields supplied by the other generators and replaces each supplied value as a whole. In particular, per-species maps and coordinate arrays must not retain stale entries or accumulate on repeated generation. Do not assign a newly generated object to the entire `init` section, and do not enable recursive object merging here. -Array example: +`add_nkstot()` only sets its own field: ```cpp -Json::jsonValue row = Json::jsonValue::array({x, y, z}); +init_section()["nkstot"] = nkstot; ``` -Append a completed SCF record with: +## Output-record lifecycle -```cpp -Json::AbacusJson::append_json({"output", -1, "scf"}, scf); -``` +The workflow starts each record with `init_output_array_obj()` **before** the corresponding solver writes SCF or other result data. That function alone creates the `output` array and appends the initial record. It rejects an existing `output` value that is not an array; an explicit `null` is not treated as a missing field. -Construct complete sections or arrays locally before storing them where practical. `gen_general_info()` assigns its complete section once. `gen_stru()` constructs each structure field locally, and `gen_init()` does the same for calculation metadata. These two generators share `init` with `add_nkstot()`, so they replace only their own fields through a file-local helper; they must not replace the entire `init` object and discard fields written by another generator. +The existing workflow entry points own this initialization: -For a current output record, coordinates, magnetic moments, the cell, forces, and stress are replaced as complete arrays. Repeating the geometry update for the same record therefore does not accumulate extra rows. Only genuinely sequential data, such as `output` records and `scf` iteration records, use `append_json()`. +| Workflow | Record initialization | +| --- | --- | +| SCF/relaxation | `Relax_Driver::iter_info()` starts the record, except for the first `ks-lr` step described below. | +| `ks-lr` | `ESolver_LR::before_all_runners()` starts the record before its embedded KS calculation; the first relaxation-driver step reuses it. | +| UnitCell-backed MD | `Run_MD::md_line()` starts a record at the beginning of each MD iteration when `mdcell.has_backing_unitcell()` is true. | +| Socket/i-PI | `SocketHandlers::handle_posdata()` starts a record before running the solver for the received `POSDATA` frame. | -## Addressing array elements +Do not move record creation into individual field writers, create a second record for the same step, or reset the whole document to start a new step. -Integer path components address existing array elements. Non-negative indices count from the beginning, while negative indices count from the end (`-1` is the last element). Indexed traversal never grows an array. +The result writers use `current_output()`, a helper local to `output_info.cpp`. It rejects a missing or non-array `output`, an empty array, or a final element that is not an object. It never creates a record as a side effect of writing a result. -For example, given: +For example, inside namespace `Json` in `output_info.cpp`: -```json +```cpp +void add_output_energy(const double energy) { - "Json": { - "key6": { - "key7": [ - {"a": 1, "new": 2}, - "vasp", - "abacus" - ] - } - } + current_output()["energy"] = energy; } ``` -replace `"vasp"` with `"cp2k"` using either its forward index: +Coordinate, force, stress, magnetic-moment, and cell arrays are built locally and assigned as complete arrays. Repeatedly updating the same record must replace these arrays rather than append rows. -```cpp -Json::AbacusJson::set_json({"Json", "key6", "key7", 1}, "cp2k"); -``` - -or the corresponding negative index: +SCF iterations are different: they form a history and must be appended. `add_output_scf_mag()` creates a missing `scf` array, rejects an existing non-array history, and appends one iteration object. Its implementation uses: ```cpp -Json::AbacusJson::set_json({"Json", "key6", "key7", -2}, "cp2k"); +jsonValue& output = current_output(); +output["total_mag"] = total_mag; +output["absolute_mag"] = absolute_mag; +jsonValue& scf = *output.emplace("scf", jsonValue::array()).first; +if (!scf.is_array()) +{ + throw std::invalid_argument("JSON SCF history must be an array"); +} +scf.push_back({{"energy", energy}, {"ediff", ediff}, + {"drho", drho}, {"time", time}}); ``` -When the destination selected by an integer is itself an array, `append_json()` appends to that nested array; it does not replace the selected element. Out-of-range indices and mismatched object/array path components are errors. +`ordered_json` may invalidate references to child values when new members are inserted into their parent object. Acquire the `scf` reference after inserting `total_mag` and `absolute_mag`, and do not retain a record reference across appending another `output` record. The same caution applies to references to root sections when new root keys are inserted. -The workflow must call `init_output_array_obj()` before filling the corresponding calculation/ionic-step record. `set_json()` and `append_json()` do not create an implicit current output record when traversing `{"output", -1, ...}`. Record initialization remains the responsibility of the existing driver/solver entry points, not the generic path interface. +## Serialization and tests -## Migrating older JSON call sites +`document()` and `write_to_json()` do not perform MPI rank filtering. The existing `json_output()` wrapper writes `abacus.json` only on rank 0 in MPI builds; callers outside `module_json` should retain the existing integration wrappers. -The former `add_json(keys, value, is_array)` interface has been removed. Choose the new operation by intent, not just by the old boolean: +`write_to_json()` preserves the existing four-space formatting and reports file-open and write/close failures. It serializes the document before opening the destination, so a serialization error does not first truncate the file. Non-finite numbers serialize as JSON `null`; decimal versus scientific float notation is not part of the schema contract. -- Use `set_json()` for scalar assignments, whole-container replacement, and replacement of an indexed element. -- Use `append_json()` for adding one element to a named or indexed array. - -The old interface appended to an existing named array even when `is_array` was `false`, and it replaced an indexed element even when the flag was `true`. Neither implicit behavior is retained by the new operation names. +The tests reset the shared document through `document()` in their fixture; no access-control macro or friend accessor is needed. Focus coverage on ABACUS behavior: generated fields and units, repeated metadata updates, record initialization and SCF accumulation, invalid section types, insertion order, escaping and non-finite values through the real writer, and file errors. Do not replace removed path-walker tests with tests of nlohmann-json's generic container API. ## Code structure -The JSON implementation is organized as follows: - ```text source/source_io/module_json/ -├── abacusjson.cpp/.h # set/append path handling and file output -├── json_node.h # object-key / array-index path component +├── abacusjson.cpp/.h # shared document and file output ├── general_info.cpp/.h # general_info section ├── init_info.cpp/.h # comment and init sections -├── output_info.cpp/.h # output section +├── output_info.cpp/.h # output records and lifecycle checks ├── para_json.cpp/.h # integration-facing wrappers └── test/ # focused unit tests ``` -JSON support is compiled under `__JSON`, which is enabled by the CMake option `ENABLE_JSON`. +`init_section()` and `current_output()` are file-local helpers, not public interfaces for workflow callers. ## Guidelines for extending JSON output -When adding JSON output: - -1. Keep JSON construction in `source/source_io/module_json` whenever practical, rather than spreading nlohmann-json details into unrelated modules. -2. Pass the data required for output explicitly through function parameters. Do not add new `GlobalV`, `GlobalC`, or `PARAM` accesses merely to obtain a value for JSON output. -3. Prefer existing domain objects or small scalar/reference parameters over introducing new cross-module dependencies. -4. Use `Json::jsonValue` for compound JSON values, `set_json()` for assignment, and `append_json()` for sequence growth. -5. Preserve the existing JSON schema unless the change intentionally modifies the public output format. -6. Add or update focused tests under `source/source_io/module_json/test` for new fields and for array/object behavior. - -For example, `output_info` receives the required values as function arguments and adds them to the current output record: - -```cpp -void add_output_scf_mag(const double total_mag, - const double absolute_mag, - const double energy, - const double ediff, - const double drho, - const double time) -{ - AbacusJson::set_json({"output", -1, "total_mag"}, total_mag); - AbacusJson::set_json({"output", -1, "absolute_mag"}, absolute_mag); - AbacusJson::append_json({"output", -1, "scf"}, - {{"energy", energy}, - {"ediff", ediff}, - {"drho", drho}, - {"time", time}}); -} -``` +Keep construction in the existing schema generator, pass its required data explicitly, and avoid adding `GlobalV`, `GlobalC`, or `PARAM` access. Preserve field names, value types, units, and order unless a schema change is intentional. Add focused tests for new fields and lifecycle behavior, and update the [JSON output reference](json_para.md) when the public schema changes. -This keeps the JSON layer explicit and avoids introducing additional global dependencies into the output path. +Keep examples and new implementation code compatible with the C++11 baseline. Include complete domain-type definitions in the source or test file that needs them, keep public header dependencies minimal, and do not reintroduce access-control macros for testing. diff --git a/docs/advanced/json/json_para.md b/docs/advanced/json/json_para.md index 745e0a5f883..eba7f35022a 100644 --- a/docs/advanced/json/json_para.md +++ b/docs/advanced/json/json_para.md @@ -5,12 +5,13 @@ - [General Information](#general-information) - [Initialization Information](#initialization-information) - [Output](#output) + - [Serialization](#serialization) ## Overview -When JSON support is enabled, ABACUS writes calculation metadata and results to `abacus.json` for post-processing. +When JSON support is enabled with the CMake option `ENABLE_JSON`, ABACUS writes calculation metadata and results to `abacus.json` for post-processing using nlohmann-json.
