Release Notes

ged/ruby-pg (pg)

v1.7.0

Compare Source

Added:

• Add PG::Connection#embed_params and keyword :typename for its parameter casting. #​726
  This allows to generate SQL strings with embedded parameters for easier debugging.
• Add PG::Connection#full_protocol_version which is new in PostgreSQL-18 #​695
• Add PG::Result#each_tuple #​675
• Add PG::TypeMap#query_param_encoders to retrieve encoders. #​726
• Deduplicate result field name strings for better performance. #​750

Removed:

• Remove compatibility to ruby < 3.1 and drops support of ruby-2.7 and ruby-3.0. #​749
• Remove GLV unlocking at all functions which process data modifiable in a second thread. #​721
  This avoids possible premature garbage collection of query parameters and possible VM crash due to concurrent data manipulation.
• Remove :static_symbol result field names. #​691
• Remove enforced rpath addition when no rpath is configured in rbconfig. #​699

Fixes:

• Limit memory allocation on invalid input into PG::BinaryDecoder::Array. #​743
• Free COPY buffers when decoders raise to avoid possible memory leak in get_copy_data. #​742
• Prevent SQL injection in set_client_encoding. #​741
• Add GC_GUARD to temporary ruby objects for conninfo string to avoid it's GC'ed prematurely. #​739
• Remove option "quirks_mode" from JSON en/decoder to fix compat with json-3.0 gem. #​737
• Respect calendar type of Ruby and PostgreSQL. #​725
• Fix broken set_notice_(receiver|processor) callback after GC.compact. #​734
• Disable DNS resolution in ruby when a service file is used, so that the priority of parameters is equal to libpq. #​635
• Use RARRAY_LENINT to avoid possible overflow. #​728
• Fix possible integer overflow at PG::BinaryEncoder::CopyRow and PG::TextEncoder::CopyRow. #​714, #​715
• Avoid possible integer overflow in query parameter encoding. #​719
• Ensure conninfo is a valid C string before closing the connection to avoid a double free of PGconn. #​709
• Raise on a too large input string to PG::TextEncoder::Bytea. #​717
• Check PG::BinaryEncoder::CopyRow array input size instead of producing an invalid output.
• Remove accidentally copied "static" keyword from Copy and Record encoder. #​711
• Avoid possibility to replace typemap while being used in Copy and Record encoders and decoders. #​707
• Add GC_GUARD's for encoding converted strings sent to the server. #​705
• Fix incomplete transaction commit when thread is shutdown ungracefully. #​704
• Assign VALUE after registration per rb_gc_register_address() #​703
• Update dependencies for binary gems to PostgreSQL-18.6, OpenSSL-3.6.5, krb5-1.22.2 #​752
