Headers under Code/RDGeneral/hash and the generated cmake package config
files (rdkit-config*.cmake, rdkit-targets*.cmake, rdkitpython-config*.cmake,
rdkitpython-targets*.cmake) are currently installed without an explicit
COMPONENT, so they default to "Unspecified" and cannot be cleanly separated
from runtime artifacts by packagers that use cmake's per-component install
(e.g. -DCMAKE_INSTALL_COMPONENT=dev).
In conda-forge we split the package into librdkit (runtime) and librdkit-dev
(headers + cmake config), with librdkit installing components
"Unspecified base data runtime" and librdkit-dev installing the "dev"
component. With the current upstream tagging, the hash headers and all
cmake config files end up in librdkit instead of librdkit-dev, which both
ships build-time artifacts in a runtime package and leaves librdkit-dev
without the cmake config needed for find_package(RDKit) to work.
This commit tags all five affected install() calls with COMPONENT dev so
per-component installs work correctly. Default (non-component) installs
are unaffected.
* this is a fix, but it breaks other tests

The previous `set(CMAKE_EXE_LINKER_FLAGS ...)` replaced the variable
wholesale, which clobbers any toolchain-supplied linker flags. In
particular, conda-forge's clang_osx-64 / clangxx_osx-64 packages set
`-stdlib=libc++ -L${PREFIX}/lib -Wl,-rpath,${PREFIX}/lib` via
`CMAKE_EXE_LINKER_FLAGS`. Losing those flags causes the postgres
extension link to pick up the wrong libc++ and fail to resolve
ABI-tagged symbols on libc++ 19+:
[ 94%] Linking CXX executable rdkit.dylib
Undefined symbols for architecture x86_64:
"VTT for std::__1::basic_stringstream<...>"
"vtable for std::__1::basic_stringbuf<...>"
"vtable for std::__1::basic_stringstream<...>"
"vtable for std::__1::basic_istringstream<...>"
ld: symbol(s) not found for architecture x86_64
The missing symbols carry the `[abi:ne190107]` ABI tag introduced by
libc++ 19+ — references that only resolve against the conda-forge
libc++, not the system one the link was falling back to.
Append to `CMAKE_EXE_LINKER_FLAGS` instead so the toolchain flags
survive. The other rdkit `.dylib`s in the same build are linked via
the standard cmake toolchain path and were never affected.
Verified by building rdkit-postgresql on osx-64 + osx-arm64 via the
conda-forge feedstock (https://github.com/conda-forge/rdkit-feedstock)
with this fix applied as a downstream patch.

* CIPLabeler performance: Store vector of bonds
CIPLabelling refers to bonds by index over and over again. This
causes a measurable hit in performance in findConfigs() because
we iterate over a bitset of "allowed" bonds. For very large
molecules with many bonds, this can be a rate-limiting step!
This affects many PDB-sized structures.
2J3N goes from 0.7s to 0.25s with this change.
I had another example for which the findBondWithIdx() call was
taking 500ms of a 700ms call (after the performance update
in #9171 was implemented)

* CIP labeller: Don't calculate auxiliary descriptors unnecessarily
The first 3 rules (the constitutional rules) are pretty easy
to understand. After rule 3, we need to calculate auxiliary
stereo descriptors to break ties.
However, we _were actually_ calculating auxiliary stereodescriptors
for all centers! We should only need to calculate auxiliary
stereocenters for sites that are needed to break ties.
This cost time - it also caused errors if the auxiliary descriptors
needed a graph expansion, because bonds in the digraph might be
pointed in the wrong direction.
Example case PDB ID 4AXM
Before this commit, errored with "Could not calculate parity! Carrier mismatch"
after 14s. After this commit, completes successfully in 0.036s.
Labelled centers all match (for the centers that had labels in
the failure case).
Includes a test that I can imagine breaking with this optimization.
The reference labels are from before this change
* Ensure all "arms" of stereo bonds and atropisomer bonds are expanded
For tetrahedral centers, ranking using the constitutional rules
always expands as far as is needed (but no further). For SP2bond
and atropisomers, if the first side is not resolvable, the
second side is never visited.
If the constitutional rules don't resolve a side, we need to
label the auxiliary centers. It's important to label all
auxiliary centers that _will_ be visited, so we need to know
what centers will be visited.
This commit updates the label() call in SP2 and Atropisomer
bonds to always attempt to label both sides if using the
constitutional rule set.
The constitutional rules are cheap, and if they fail, we
always go on to the full rule set. It is not a savings to skip
the search on the second side if we're going to keep going
anyway!
Includes a test that reproduces Ricardo's example.
This has no measurable effect on performance relative to the
original solution
* If any parts of the center have been seen, label it.
I couldn't make an example hit this, but Ric is totally
theoretically right

* Speed up tautomer canonicalization by deferring on SSSR calc
* Lazy kekulization for tautomer enumeration
Defer kekulization of tautomers until they are actually needed for
transform matching. This avoids creating kekulized copies for:
1. The initial tautomer (until first iteration)
2. New tautomers that may never be processed (if enumeration ends early)
The Tautomer class now supports lazy initialization of the kekulized
form via getKekulized() method.
Performance improvement: ~7% additional speedup (total ~22-24% from baseline)
* Use count-only substructure matching in tautomer scoring
* Add SubstructMatchCount regression test
* MolStandardize: reduce enumerate overhead
* MolStandardize: avoid per-tautomer ring recomputation
* Atom: cache PeriodicTable pointer in valence calcs
* Atom: reuse PeriodicTable in getEffectiveAtomicNum
* PeriodicTable: add atomic fast path for getTable
* GraphMol: reduce ROMol copy reallocations
* MolStandardize: use quickCopy for per-match product copies
Use RWMol(*kmol, true) in tautomer enumeration to avoid copying properties/bookmarks/conformers for each candidate. This reduces deep-copy overhead without changing chemistry.
* MolStandardize: pre-filter scoring patterns by element/connectivity
For tautomer scoring, pre-compute which SubstructTerms are relevant for
a given input molecule. Since tautomerization only moves H atoms and
changes bond orders (never creates/destroys heavy-atom bonds), patterns
requiring missing elements or connectivity can be skipped for all
tautomers of that molecule.
Two-stage filtering:
1. Element check: skip patterns requiring atoms not in the molecule
2. Connectivity check: skip patterns whose bond-order-agnostic structure
doesn't match the input molecule's connectivity
This reduces the number of VF2 substructure calls per tautomer from 12
to typically 3-5, depending on the molecule's composition.
* MolStandardize: preserve molecule properties for canonical tautomer
Copy molecule properties from the original input to the canonical tautomer
result. Since quickCopy during enumeration skips d_props to avoid overhead,
extended SMILES data like link nodes (LN) was lost. This restores them
on the final result.
* TautomerQuery: preserve molecule properties (e.g. link nodes) in tautomers
TautomerQuery::fromMol() uses TautomerEnumerator::enumerate() which uses
quickCopy for performance. This doesn't copy molecule properties like
_molLinkNodes. Without this fix, XQMol output would lose link node
extensions in the SMILES.
Copy properties from the original query molecule to all enumerated
tautomers before constructing the TautomerQuery. This preserves extended
SMILES data without impacting enumeration performance.
* MolStandardize: use parallel iteration and cache bond lookups
Replace O(n) getAtomWithIdx/getBondWithIdx calls with parallel iteration
over atom/bond ranges in canonicalizeInPlace and enumerate. Cache bond
lookups in setTautomerStereoAndIsoHs to avoid repeated O(n) searches.
* perf: add specialized matchers for simple tautomer scoring patterns
Replace VF2 graph matching with O(n) loops for 6 simple patterns:
- countDoubleOrAromaticBonds: C=O, N=O, P=O patterns
- countMethyls: [CX4H3] methyl groups
- countCarbonDoubleHetero: [C]=[/home/dcvuser/rdkit;Code/GraphMol/MolStandardize/Tautomer.h] aliphatic C=hetero
- countAromaticCarbonExocyclicN: [c]=aromatic C=exocyclic N
Complex patterns (benzoquinone, oxim, guanidine, aci-nitro) still use VF2.
Combined with the pre-filtering optimization, this achieves ~3.7x speedup
(~2500ms vs ~9300ms original) for tautomer canonicalization.
* Fix tautomer canonicalize dropping conformers from quickCopy
quickCopy (RWMol(*mol, true)) skips conformers, so tautomer
enumeration products lose 2D/3D coordinates. This causes InChI
generation to omit the /b (double bond E/Z stereo) layer, since
E/Z is derived from atomic coordinates.
Fix: copy conformers from the original molecule onto the canonical
tautomer after pickCanonical in TautomerEnumerator::canonicalize().
Tests: SMILES-based E/Z check in testTautomer.cpp, molblock-based
conformer preservation check in catch_tests.cpp.
* add test on canonicalize losing stereo
* add regression test for exocyclic C=C tautomer canonicalization
The getTautomerStateKey() pre-filter (commit 2595ef748) can falsely
deduplicate distinct tautomers when their atom-index-ordered state
patterns happen to match, leading canonicalize() to pick the wrong
canonical form for molecules with STEREOTRANS-pinned exocyclic C=C
bonds after RemoveHs.
Test verifies that O=C(CC1=CC2=CC=COC2)NC1=O canonicalizes to the
exocyclic form O=C1CC(=CC2=CC=COC2)C(=O)N1, not the endocyclic form
O=C1C=C(C=C2CC=COC2)C(=O)N1.
Currently expected to FAIL until the state key dedup bug is fixed.

V3000 parsing sets aromatic flags on bonds but not atoms. When removeHs
strips an explicit H from nitrogen in an aromatic ring, molRemoveH
checked heavyAtom->getIsAromatic() to decide whether to increment
numExplicitHs — but that flag was always false for V3000-parsed atoms.
Without the explicit H count, the kekulizer cannot distinguish pyrrole N from pyridine N,
causing
"Can't kekulize mol" errors on valid ChemDraw-exported molblocks.

flags
* switch the Query infrastructure to use std::function

Removed commented-out function pointer declarations for match and data functions.
* Add RDLog::CaptureLog for capturing log messages
Adds an RAII `CaptureLog` class to `namespace RDLog` (alongside the
existing `LogStateSetter`) that redirects an RDKit logger's output to an
internal `std::stringstream` for the duration of its lifetime. On
destruction the original stream destination and enabled state are fully
restored. Nesting is supported: an inner capture shadows the outer one
and each collects its own messages independently.
The default constructor captures `rdErrorLog`; an explicit constructor
accepts any `RDLogger`. Both enable the logger if it was previously
disabled and restore that state on destruction.
Python bindings expose `rdBase.CaptureLog` as a context manager with a
`messages` read-only property, mirroring the existing `rdBase.BlockLogs`
pattern. Messages remain accessible after the `with` block exits.
C++ tests are added to `catch_logs.cpp` (6 Catch2 sections covering
basic capture, empty state, enable/restore, stream restore, explicit
logger, and nested captures). Python tests are added to
`UnitTestLogging.py` (6 unittest cases covering the same scenarios).

* CaptureLog: add per-level properties (error_messages, warning_messages, etc.)
The Python CaptureLog wrapper now captures all four log levels
simultaneously. Per-level properties (error_messages, warning_messages,
info_messages, debug_messages) give access to messages from each logger
independently; the existing messages property returns them all combined.
The C++ RDLog::CaptureLog class is unchanged — it remains a clean
single-logger RAII type. The Python wrapper composes four instances of
it, one per log level.
Suggested by bp-kelley in PR review.

* Refactor CaptureLog: add named per-level subclasses
Add CaptureErrorLog, CaptureWarningLog, CaptureInfoLog, and CaptureDebugLog
as named convenience subclasses of CaptureLog, each capturing a specific
logger. Update Python bindings to expose the four named classes directly
(dropping the combined multi-capture approach), and update tests accordingly.

* Simplify CaptureLog: no argument, captures rdErrorLog only

logger it captures and avoids redundancy within namespace RDLog.

* Generalize CaptureErrorLog into CaptureLog with logger parameter
Replace CaptureErrorLog with CaptureLog, which accepts any RDLogger in
its constructor (e.g. rdErrorLog, rdWarningLog). Add CaptureErrorLog as
a convenience subclass that pre-fills rdErrorLog, preserving backward
compatibility for existing callers.
