Add concat || operator to agtype #1198

Zainab-Saad · 2023-08-28T07:34:09Z

This patch is originally authored by Josh Innis for #282 . I have verified, extended the functionality and added more regression tests for concat operator (which is one of the operators among ?,?|,?&,->,->>,#>,#>>,|| implemented in the original patch)

@Zainab-Saad @MuhammadTahaNaveed I should have checked this earlier, sorry. Please update the commit extended description to describe this PR a bit more.

- Implement the concatenation operator for agtype as operands, similar to the one in postgres where this operator works with jsonb operands - Allow using concat operator inside cypher queries - Add jsonb_operators.sql and jsonb_operators.out files for containing regression tests related to jsonb operators, i.e., (?,?|,?&,->,->>,#>,#>>,||)

Implemented integer conversion to boolean in both toBoolean and toBooleanList functions. Also made corresponding changes to regression tests and broke long lines to adhere to the 79-column line length limit in the toBooleanList function. Minor fix in `agtype_volatile_wrapper` function (apache#1172) Fixed duplicated IF-STATEMENT of INT4OID in agtype_volatile_wrapper function changing it to INT2OID Update files for Apache AGE release 1.4.0 (apache#1194) Changes to be committed: modified: Makefile modified: README.md modified: RELEASE renamed: age--1.3.0.sql -> age--1.4.0.sql modified: age.control Removed unnecessary assignment (apache#1185) Original work was done by Panagiotis Foliadis in PR apache#1035. Co-authored-by: Panagiotis Foliadis <[email protected]> Fix Issue#1159: Server terminates for SET plus-equal (apache#1160) The previous implementation of alter_properties() in agtype.c while copying the original properties ignored non-scalar value cases, this PR fixes that Add concat || operator to agtype (apache#1198) - Implement the concatenation operator for agtype as operands, similar to the one in postgres where this operator works with jsonb operands - Allow using concat operator inside cypher queries - Add jsonb_operators.sql and jsonb_operators.out files for containing regression tests related to jsonb operators, i.e., (?,?|,?&,->,->>,#>,#>>,||) Add exist(?, ?|, ?&) operators for agtype (apache#1218) - Added exist(?, ?|, ?&) operators for agtype similar to jsonb operators in postgresql. - Allow exist(?, ?|, ?&) operators to be used inside cypher queries. - Added regression tests. Add additional index support and performance enhancements (apache#1232) Added additional index support for the WHERE clause. This work was partly from another patch authored by Josh Innis. Changed the volatility flag to IMMUTABLE for many functions related to indexes. I.e. comparison and build functions. Updated _agtype_build_path to be IMMUTABLE. No regression tests were impacted by these changes. Add path extraction(#>, #>>)operators to agtype (apache#1224) Original work was done by Josh Innis for issue#282. The changes included in this PR are as follows: - Implement the path extraction operators for agtype, similar to the one in postgres where this operator works with jsonb operands - Allow using these operators inside cypher queries - Added regression tests Update the Python Driver (apache#1246) - Updated the README contents of the Python driver for the pypi release. - Fixed errors in test_age_py.py that was causing connectivity issues. Refactor the IN operator to use '= ANY()' syntax (apache#1236) This change reduces use of internal function calls from the IN implementation to optimize performance. This also changes IN behavior to correctly return NULL upon NULL elements included in the list that IN checks against. Added and corrected regression tests. Co-authored by: Josh Innis <[email protected]> Update Discord channel in README.md (apache#1253) Add missing dependency in cypher_expr.c (apache#1256) The function contain_vars_of_level() was missing a header. Added that header to prevent a warning during compilation. Extend access(->, ->>), addition and subtraction operators (apache#1258) Original work was done by Josh Innis for issue#282. The changes included in this PR are as follows: - Enable the use of access operator with agtype as the RHS operand, allowing this operator to be used within cypher queries - Extend addition operator to concatenate in case any or both operands are non-scalar or scalar vertex/edge/path - Extend subtract operator to delete specified keys from object or elements at specified indexes from array - Add and modify regression tests relevant to the above changes Optimize performance of detach delete (apache#1271) Previously, for each vertex to be deleted, all edge tables were scanned once to process the connected edges. Now, this task is postponed until all vertices are deleted. So, the connected edges can be processed in only one scan of the edge tables regardless of the number of deleted vertices. Refactor Regression Tests for CASE statement (apache#1268) Added some new cases to CASE statement regression tests to capture cases that were not tested for before. Refactored existing test cases to improve readability Extend EXPLAIN and add config param to switch transformation of property filter (apache#1262) * Add explain options Explain command in the following format is supported now: `EXPLAIN (VERBOSE, COSTS OFF, FORMAT XML) ...` Note that, this is basically Postgres' EXPLAIN command, and the purpose of this is to support debugging and regression tests. * Add config param to switch transformation method of property filter When the `age.enable_containment` parameter is on, the agtype containment operator is used to transform property filter. When off, access operator is used instead. The former case is preferable for GIN index, and the later for BTREE expression index. The idea of replacing containment with access operator in order to support BTREE index is taken from a patch by Josh Innis. A note on regression testing- although there are test cases for the `age.enable_containment` parameter, sometimes it may be useful to set this parameter before running any tests (not just the ones related to it). For example, when the logic related to property transformation changes. It can be set in the `age_regression.conf` file. Implemented age_tail function (apache#1283) age_tail() function returns a list containing all the elements, excluding the first one, from a list. Optmize vertex and edge builder functions (apache#1252) Changes: - Added the agtype_raw module, which contains helper functions to build agtype directly without building an agtype_value first - Optimize _agtype_build_vertex and _agtype_build_edge functions The agtype_raw module: Inserting a composite agtype (i.e. object) into another agtype (i.e. as an array element) requires the first agtype to be deserialized into agtype_value. Then, the agtype_value to be serialized back into the second agtype. This module provides functions that can perform such insertion without deserializing first. It is meant to speed up queries that does deserialization-serialization back and forth involving deeply nested agtype objects. docs: Add to Docker setup (apache#1204) - add command to enter psql interface from command line. Fix Issue 945 - incorrect count(*) return values (apache#1288) Fixed issue 945 where count(*) would have incorrect return values. NOTE - We need to re-evaluate if we want to use output_node or not. If output_node is set to false, then it basically short circuits match for instances where a variable isn't specified - MATCH () RETURN 0; MATCH () MATCH () RETURN 0; While, on the surface, this appears to be a good way to improve execution time of commands that won't do anything, it also causes chained commands to not work correctly. This is because a match without a variable will still feed its tuples to the next stage(s) even though they won't necessarily be sent to the output. For example, with count(*) - MATCH () RETURN count(*); MATCH () MATCH RETURN count(*); With output_node set to false, it won't send the tuples. We will likely need to remove all of the output_node logic. However, this needs to be reviewed. For now, we just set it to true and update the output of the regression tests. Updated regression tests to accomodate the change. Added new regression tests to cover overlooked cases. Fix issue apache#1302 - crash on NULL input to UNWIND (apache#1304) - Added a check for NULL input in age_unnest. - Added regression tests. Fix Issue 1305 - drop_label NULL cases (apache#1306) Fixed issue 1305 where drop_label doesn't cover the case of rel_name coming back NULL, meaning it wasn't found. Additionally, added a fix for when the schema_name isn't found from the namespace id search. Added regression tests Fix issue 1303: Server crashes on executing SELECT * FROM agtype(null); (apache#1317) * Add additional checks for Const expression nodes for which the walker code would crash. * The server crashes for few other expr types too including Const, OpExpr, Var, BoolExpr and CoerceViaIO for which checks are added * Add regression tests Extend agtype containment operators (@>, <@) (apache#1285) This PR is part of the patch originally authored by Josh Innis for issue # 282. The work included in this PR is as follows: - Enable the usage of left and right containment operators inside the cypher queries - Extend this operator to be used with scalars - Add relevant regression tests Fix issue apache#1045 - error using path var in WHERE (apache#1295) - Added cypher_path as an entity(along side cypher_node and cypher_relationship) in order for WHERE in MATCH clause to be able to reference it. - Fixed relevant error messages to be more specific. - Added regression tests. Modify COUNT() to output agtype (apache#1311) Modified the make_function_expr logic to wrap the PG COUNT() function with a cast to agtype. This enables COUNT() to be used as a subquery in CASE. Also added logic for casting for future PG function additions. This modification passes all regression tests. Also added regression tests for COUNT in CASE statements. Fix Issue 1329 - agtype_to_int4 crash (apache#1339) Fixed issue 1329 where `agtype_to_int`<8,4,2> and `agtype_to_int4_array` crashed due to not properly checking input. As these functions take "any" input, the input has to be properly checked before casting it to a specific type. The input section assumed it was agtype, which caused crashes for non-agtypes. The functions `agtype_to_int`<8,4,2> will convert non-agtypes into agtype. However, there were no regression tests for this. The functions `agtype_to_int`<8,4,2> will convert non-agtypes to agtype ints but, did not for their string equivs. Meaning, passing a ('true') or ('3.14') would fail but, passing a (true) or (3.14) would not. This has been corrected for all 3 functions. TODO - The function `agtype_to_int4_array` only takes agtype, currently, and we should consider allowing it to take "any" types. Added regression tests. Added missing regression tests. Fix issue apache#1347 - unknow type of agtype container 0 (apache#1349) The error was caused by the Datum referenced by edge_entry->edge_properties becoming non-persistent. As a result, the pointer becomes dangling. This issue is fixed by making a copy of the Datum into the MemoryContext it is used. The fix is also applied to vertex_entry->vertex_properties. Thanks to John for finding out the correct function to copy a Datum. Co-authored-by: John Gemignani <[email protected]> Clean up agtype_to_int8, agtype_to_int4, & agtype_to_int2 (apache#1354) Cleaned up the code in `agtype_to_int8`, `agtype_to_int4`, and `agtype_to_int2`. There was some dead code after implementing PR 1339. Additionally, modified the error messages to be a bit more helpful and modified the logic to cover a few more cases. Added more regression tests. Fix typo in agtype_raw.h header guard (apache#1368) Header guard AG_AGTYPE_RAW_H was misspelled AG_AGTYPE_RAw_H Implement EXISTS subquery for CASE (apache#1345) Modified logic of EXISTS to wrap itself in a agtype cast. This allows EXISTS to work with in CASE statements, among other implementations that may require an agtype. Also renamed the wrapper function to be more generic to denote its usage in other implementations if need be. Added regression tests for EXISTS Fix ambiguous conditions (apache#1373) - These conditions were ambiguous for compiler as well as for other devs. Fix DockerHub warning messages for latest (apache#1380) Fixed DockerHub warning messages for the build 'latest'. These were due to Assert statements that used variables that were not used for anything else. I changed them to ifs with error log outputs. Fix issue apache#1389 - Server crash on using null operand for access operators (apache#1390) - The issue was due to code not handling null values as LHS operands for access operators(->, ->>) Added check for this case and included regression tests Remove unnecessary #include in src/backend/utils Removed unnecessary #includes in src/backend/utils files. Fix issue apache#1399 EXISTS doesn't handle non-existent labels (apache#1400) Fixed issue apache#1399 where EXISTS doesn't handle non-existent labels. However, the issue actually is due to the extra processing (read: extra distance between the AST nodes) that prevented the transform logic from being able to resolve variables created in previous clauses further than one parent up. Added logic to allow the `find_variable` function to search up the parent parse nodes. Added regression tests to cover these cases. Implement chained expression order of operations (apache#1402) Implements functionality for order of operations (parentheses) in chained operations. Added new nodes and functions to accomodate this feature. Added relevant regression tests for order of operations in chained expressions. Modified a previous regression test case that had its location reporting changed by this implementation. Converted SQL mail into multiple files. (apache#1401) Converted SQL mail into multiple files. This pull request is aimed at improving the overall quality of our SQL codebase by converting the main SQL (age-x.x.x.sql) file into multiple smaller files in the sql directory. The primary goal is to enhance code readability, maintainability, and organization for the benefit of the development team. Fix issue apache#1398 - SET followed by DELETE does not delete (apache#1412) In the DELETE executor, tuples were being locked\deleted using the command ID returned by GetCurrentCommandId(). However, the original tuples were retrieved using a command ID stored in the estate. To fix it- before the retrieval of a tuple, estate command IDs are set using GetCurrentCommandId() so it matches if the tuple is to be deleted later. Additional changes: ------------------- Fixed an incorrect cypher_delete test. The query `MATCH (n1)-[e]->() DELETE n1, e RETURN n1` should be able to delete n1 and e without requiring DETACH DELETE. TODO: ----- It may be a good idea to audit the executors for any inconsistent use of command IDs. Fix issue 1393 - previous clause variables not seen with EXISTS (apache#1426) Fixed issue 1393 - Unexpected error when matching nodes that are connected to nodes resulted from a previous MATCH clause. Basically, variables from the previous clauses where not seen when using the EXISTS clause for path pattern matches. This only affected EXISTS and only for the EXISTS (anonymous_path) grammar component. The original issue was only with vertices, but this also affected edges. Both cases are now fixed. Fixed 1 regression test that was incorrect. Added regression tests. Add support for chained expressions in CASE (apache#1431) Adds logic that implements CASE in chained expressions. Adds regression tests for CASE chained expression logic. Fix issue 1219 - MERGE not seeing previous clause var (apache#1441) Fixed issue 1219 where MERGE did not see the previous clause's variable. This description is a bit misleading as the transform phase did see the variable and was able to use it. However, the planner phase removed the variable by replacing it with a NULL Const. This caused MERGE to see a NULL Const for the previous tuple, generating incorrect results. However, this only occurred for very specific cases. Fx: MATCH (x) MERGE (y {id: id(x)}) -- worked MATCH (x) MERGE (y {id: id(x)}) RETURN y -- didn't MATCH (x) MERGE (y {id: id(x)}) RETURN x, y -- worked The change impacted no current regression tests and involved wrapping all explicitly defined variables' target entries with a volatile wrapper. Added new regression tests. Fix Docker file to reflect PostgreSQL version 15 (apache#1449) Fixed the following Docker file to reflect running under PostgreSQL version 15. modified: docker/Dockerfile.dev This impacts the development DockerHub builds. Master to PostgreSQL version 16 (apache#1451) * Initial PG16 version (apache#1237) Fixed empty string handling. Previously, the PG 16 outToken emitted NULL for an empty string, but now it emits an empty string "". Consequently, our cypher read function required modification to properly decode the empty string as a plain token, thereby addressing the comparison issue. Compared the branches and added the necessary changes so that the query's rteperminfos variable doesn't stay NULL. Fix missing include varatt.h (causing undefined symbol VARDATA_ANY) & Fixing some test cases of the failings Added missing include varatt.h to fix the undefined symbol while loading age into postgresql because usage of VARDATA_ANY needs to import varatt.h in PG16 Modified initialisation of ResultRelInfo and removed unnecessary RTEs Compared the branches and added the necessary changes so that the query's rteperminfos variable doesn't stay NULL. Modified initialisation of ResultRelInfo and removed unnecessary RTEs One of the problems that we were facing was related to the ResultRelInfo pointing at the wrong RTE via its ri_RangeTableIndex. The create_entity_result_rel_info() function does not have the capability of setting the ri_RootResultRelInfo to the correct ResultRelInfo node because it does not have access to the ModifyTableState node. The solution for this was to set the third argument in InitResultRelInfo() to be zero instead of list_length(estate->es_range_table). In the update_entity_tuple() function, when we call table_tuple_update() and assign the returned value to the result variable, the buffer variable receives the value of 0. Made a workaround so that the original value isn't lost. This is a work in progress for the new field that was added to the struct Var called varnullingrels. According to the documentation, this field is responsible for marking the Vars as nullable, if they are coming from a JOIN, either LEFT JOIN, RIGHT JOIN, or FULL OUTER JOIN. The changes were made following an "optional match" clause which is being treated as a LEFT JOIN from our extension. A function markRelsAsNulledBy is added because its internal in Postgres and doesn't belong in a header file, therefore it can't be exported. This function is added before the creation of the Vars from the make_vertex_expr and make_edge_expr, to correctly mark the specific PNSI as nullable, so later in the planner stage, the Vars will be correctly nulled. Fix incorrect typecasting in agtype_to_graphid function. Fix incorrect returns to the fuction _label_name, _ag_build_vertex and _ag_build_edge.

The column references to a nullable RTE within the join's RTE are also marked as 'nullable'. This concept is introduced in Postgresql v16. The change in Postgresql v16's pullup_replace_vars_callback() function causes different plans to be generated depending on whether appropriate RTEs are marked nullable. Without marking nullable, in a left join, any function call expression containing right RTE's columns as arguments are not evaluated at the scan level, rather it is evaluated after the join is performed. At that point, the function call may receive null input, which was unexpected in previous Postgresql versions.

The documentation needed to clarify what was needed. The installer needed to be fixed. The CI file needed to have the updated Go versions. The driver installation for Linux will no longer install Java, Golang, or ANTLR for the user. This is left to the users system administrator. Instead, it will validate the current installation of those components, then build and install the driver. Also updated - modified: drivers/golang/go.mod modified: drivers/golang/go.sum Update age_load to make property value conversion optional (apache#1525) This is an addition to a previous patch that introduced loading property values from CSV files as agtype. This behavior is made optional in this patch with a boolean function parameter `load_as_agtype`. When this parameter is false, values are loaded as string. Update README.md (apache#1526) Amended AGE community at bottom of Readme file. - Github issue and discussion link added - Link to Discord was deleted. - Added Stack overflow with questions and answers comment - Changed Twitter as X Fix unsorted output of some queries in the cypher_match test (apache#1507) Fix unsorted output of some queries in the cypher_match test Add optional parameter '=' in property constraints (apache#1516) - The '=' operator checks if the original property value(as a whole) is equal to the given value. e.g MATCH (n {school:{addr:{city:'Toronto'}}}) tranforms into either(in case age.enable_containment is off) `properties.school.addr.city = 'Toronto'` or(in case age.enable_containment is on) `properties @> {school:{addr:{city:'Toronto'}}}` But MATCH (n ={school:{addr:{city:'Toronto'}}}) will tranform into either(in case age.enable_containment is off) `properties.school = {addr:{city:'Toronto'}}` or(in case age.enable_containment is on) `properties @>> {school:{addr:{city:'Toronto'}}}` - Added @>> and <<@ operators. Unlike @> and <@, these operators does not recurse into sub-objects. - Added regression tests. - Added changes in sql files to version update template file. Update Go installation and add in parser files (apache#1582) Updated Go installation and added in built parser files. While the parser files can be built by the user, there may be instances where the user doesn't have the ability to do so. For the latter case, they have been added. modified: drivers/golang/go.mod modified: drivers/golang/go.sum new file: drivers/golang/parser/age_base_listener.go new file: drivers/golang/parser/age_base_visitor.go new file: drivers/golang/parser/age_lexer.go new file: drivers/golang/parser/age_listener.go new file: drivers/golang/parser/age_parser.go new file: drivers/golang/parser/age_visitor.go Implement list comprehension (apache#1610) * Add initial code for list comprehension - Additionally, fixed a bug in nested queries. * Resolve variable scope and ambigous variable issue - For scoping the variable, remove the pnsi from namespace list after being used by the list comprehension. - To resolve the ambigous variable issue, only scan the pnsi of list_comp subquery. * Fix non agg plan node issue in list comprehension - Resolved the issue 'aggref found in non-agg plan node' when the list comprehension is used as a property constraint in MATCH and other clauses or when used in WHERE clause. Intead of adding qual in the jointree, we are now adding the qual in having node of query. e.g. MATCH (n {list: [for i in [1,2,3]]}) MATCH (n) WHERE n.list=[for i in [1,2,3]] WITH n WHERE n.list=[for i in [1,2,3]] - Removed redundant call to function tranform_cypher_clause_with_where by tranform_match_clause. * Resolve variable reuse issue in list comprehension - Also, for scoping list comprehension variable, instead of removing the pnsi of list comp from namespace, now we just mark the cols of pnsi as not visible. * Modify grammer to match opencypher list comprehension grammer - Also added initial regression tests for list comprehension * Add regression tests for bugs resolved - Includes tests for nested cases, ambigous variable issue, list comprehension variable scoping and planner node aggref issue. - Should be added more. * Resolve invalid output on multiple list comprehensions - Fix the output of multiple list comprehensions in the RETURN clause and the WHERE clause. - Added regression tests for the above and some for the previous bugs resolved. * Fix aggref found where not expected issue (apache#189) - Resolved the 'aggref found where not expected' error thrown when using list comprehensions in UNWIND, or as a property update expression in SET or in the comparison expressions, typecasts or string matching in WITH - WHERE clause - Added an error to be thrown when using aggregation functions in UNWIND and property update expr in SET clause - Added regression tests * cleanup: Remove dead code and formatting changes --------- Co-authored-by: John Gemignani <[email protected]> Co-authored-by: Zainab Saad <[email protected]> Fix Issue 1630: MERGE using array not working in some cases (apache#1636) This PR fixes the issue where some previous clause user variables were not getting passed to the next clause. Basically, there is a function, remove_unused_subquery_outputs, that tries to remove unnecessary variables by replacing them, in place, with a NULL Const. As these variables are needed, we need to wrap them with the volatile wrapper to stop that function from removing them. Added regression tests. Fix Issue 1634: Setting all properties with map object causes error (apache#1637) Fixed the issue where setting the properties would not work, if it where an object passed as the properties. Added regression tests. Implement EXISTS Subquery (apache#1562) * Add grammar rules for exists subquery Add grammar rule for exists subquery. EXISTS subquery can be used with UNION and does not have to feature a RETURN. Regression tests not yet added. * Implement EXISTS Subquery Implements a naive version of EXISTS subquery that evaluates the underlying subquery. Add regression tests related to EXISTS TODO: Implement logic to allow the underlying subquery to constrain the queries in the outer scope. Also fixes a minor typo. Allow agtype_build_map to use AGTYPE keys (apache#1666) Added the ability for agtype_build_map to use AGTYPE keys. In doing this, age_tostring needed to be broken up and rewritten to handle UNKNOWNOID. This rewrite allows other functions to use the logic in age_tostring without using age_tostring directly. Additionally, rewrote age_tostring as a ("any") type function; it used to be a (variadic "any"). The logic here can be used to re- write other (variadic "any") functions that have a set number of input parameters. Added regression tests. Sample code for AGE-JDBC driver (apache#390) * sample code for age-jdbc-drivers * cleaned the code * update query statement Add hooks for multi-arch builds on dockerhub (apache#1683) - hooks/build overrides the default build command to use buildx and create an image for amd64 and arm64 archictectures. The arm64 build will take time to build as it is emulated using qemu. - hooks/push overrides the default push command to push the multi-arch images. The push is initiated from the buildx context since we have the push argument(--push) set in the buildx command. Implement map projection (apache#1710) Adds support for openCypher Map Projection specification. Update README.md (apache#1713) Remove Discord Badge in README.md Fix Issue 1691 - MERGE incorrectly creates multiple vertices (apache#1718) Fixed issue 1691 where MERGE would incorrectly create multiple vertices. This only occurred when MERGE was being driven by a previous clause. NOTE: To be more correct, the issue is with creating duplicate paths. The reason this happened was due to the visibility of tuples that were created during the MERGE instance. It is not possible to add them in to be rescanned. Because of this limitation, it required adding the ability to MERGE to know what path an instance had already created. Added regression tests. Fix shift/reduce conflict in grammar (apache#1719) - The grammar had a shift/reduce conflict due to the ambiguity of the `IN` keyword. This is resolved by adding generic rule and manually resolving to the correct specific rule. - Added additional test cases. Fix Issue 1709 - MERGE creates incomplete vertices after the first one (apache#1721) Fixed issue 1709 where MERGE appears to create incomplete vertices after the first one. However, the real issue was that SET wasn't seeing the newly created tuples from MERGE. This was due to an incorrect cid when performing the tuple insert in MERGE. The issue was that the cid was being overwritten in the function insert_entity_tuple_cid. Once this was corrected, everything worked fine. Added regression tests. Update README.md (apache#1720) 1) Simplified the Introductory Section 2) Deleted the [Community] section Remove duplicate check (apache#1740) This commit removes [a benign] redundant check for label validity Added Networkx Support in python driver (apache#1716) Co-authored-by: munmud <[email protected]> Update README.md (apache#1728) - Review the Quick Start section in order to make it more concise and less redundant. - The commands weren't working if issued in the written order. - I kept only the commands that create entities with labels and properties, rather than separate commands for each step. Add helpful messages to the VLE subsystem (apache#1742) Added helpful messaging to the VLE subsystem. These changes are due to issue 365 where there was an issue with the VLE that turned out to not be with the VLE. Basically, there is a way, apparently, to have a malformed edge or possibly one not fully removed. When the VLE subsystem does its load on the graph, it would error out on these edges as this was considered to be a potential data corruption issue. The changes added are to report and ignore these edges. Reporting them, so as to allow the user to take corrective action by removing them. Ignoring them, as they are likely not relevant to the query. Basically, leaving it up to the user to decide. No impact to current regression tests. Add the command graph_stats and improve VLE messaging for load (apache#1750) Added the command graph_stats. This command will force a reload of the specified graph. This is done to generate current statistics and dump any warning messages about the graph generated during a the load. Cleaned up some messaging from the VLE load process for duplicate vertices and edges. Added regression tests.
