williamfisetalgorithms	generic segment tree min max range update bug	Bug	the generic segment tree implementation seem to be suffer from two issue when use multiplication range update with min max range query the segment tree doesn t seem to handle overflow well hard to avoid with multiplication update in general or at least the result doesn t match with the test value this may be because the segment tree only capture the min max value in a segment and when this value overflow the true min max be lose not sure how much can be do here perhaps just ensure no overflow can happen in the test update involve negative value aren t be handle I m not certain this can be handle with the current framework I think we may need to keep track of more information it may be worth investigate if a shadow min segment tree or a pair of value on the segment node can be useful for a max segment tree for this situation and vice versa when we encounter a negative value my idea be that for a max segment tree when a negative value be encounter the maximum value would become the minimum value in a min segment tree I don t know if this work but I think it s in the right direction java long ar 2 1 3 4 1 genericsegmenttree st new genericsegmenttree ar genericsegmenttree segmentcombinationfn max genericsegmenttree rangeupdatefn multiplication st rangeupdate1 0 4 1 assertthat st rangequery1 0 4 isequalto 4 negative number be a known issue st rangeupdate1 0 4 2 assertthat st rangequery1 0 4 isequalto 2 return 8 as max but should be 2
williamfisetalgorithms	suffix array improvement	Enhancement	to polish off the suffix array datum structure we still need to add test automate detect alphabet shift size finish nlogn construction x refactor sa class
williamfisetalgorithms	modpow function break	Bug	modpow function in mathematic folder be break in particular the function fail for some negative exponent to debug compare against the biginteger modpow method be a good place to start
williamfisetalgorithms	improve priorityqueue construction to o n with heapify	Enhancement	when a binary heap be create from a primitive array of value we heapify the array to create a binary heap in o n however when a collection be pass into the constructor we lazily add element to the pq result in o nlog n construction let s investigate if we can also heapify the collection constructor o n construction with heapify l29 o nlog n construction without heapify l42
williamfisetalgorithms	empty eulerian path bug	Bug	from a comment I get on youtube that need investigation if the graph have 3 node 0 1 2 and the indegree and outdegree of all the node be 0 then there be an empty eulerian path but the code result in 0 do you think findstartnode can be enhance to handle this edge case relevant video euler path circuit existence euler path circuit algorithm euler path circuit source code code test we should add test for this edge case and or fix the code
williamfisetalgorithms	suffix array lcs break	Bug	investigate the behavior of the lcs method under different k value to determine if it s work properly especially with long string I haven t look into the detail yet but assume the initial approach be still correct and there s just a bug in the code which be quite possible it may be worth investigate to see if we can swap out the current sa implementation with the slow but more stable implementation if that doesn t work I can also swap out the slide window minimum with a min range query segment tree to see if I get a different result
williamfisetalgorithms	cut polygon additional point	Bug	the cut polygon snippet seem to provide additional point when a cut operation be perform which probably shouldn t be there for example when the follow run the additional point 2 2 appear out of nowhere java pt squarepolygon new pt 0 0 new pt 0 4 new pt 4 0 new pt 4 4 pt p1 new pt 1 1 pt p2 new pt 5 5 pt poly1 cut squarepolygon p1 p2 pt poly2 cut squarepolygon p2 p1 system out println first polygon for pt pt poly1 system out println pt print first polygon 4 0 4 0 0 0 0 0 0 0 4 0 2 0 2 0 probably should not be here system out println nsecond polygon for pt pt poly2 system out println pt second polygon 4 0 4 0 0 0 0 0 2 0 2 0 probably should not be here 4 0 0 0 finnlidbetter assign you since make this snippet right perhaps you can offer some insight

antlrantlr4	integrate antlr4 into oss fuzz	Question	hi all I have prepare the initial integration of antrl4 into google oss fuzz this will enable continuous fuzzing of this project which will be conduct by google bug that will be find by fuzzing will be report to you after the initial integration of this project into oss fuzz I will continue to add additional fuzz test to improve the code coverage over time the integration require a primary contact someone to deal with the bug report submit by oss fuzz the email address need to belong to an establish project committer and be associate with a google account as per here when a bug be find you will receive an email that will provide you with access to clusterfuzz crash report and fuzzer statistic more than 1 person can be include please let I know who I should include if anyone jazzer be use for fuzze java application jazzer be a coverage guide in process fuzzer for the jvm platform develop by code intelligence it be base on libfuzzer and bring many of its instrumentation power mutation feature to the jvm jazzer have already find several bug in jvm application jazzer finding finding please let I know if you have any question regard fuzzing or the oss fuzz integration
antlrantlr4	literal unicode symbol in grammar	Question	if I generate a lexer for the java target with a grammar that contain literal unicode symbol encode in utf 8 e g lexer grammar lex forall the generate lexer differ when generate on different platform linux window in this case as far as I understand this be because when you do not supply the encoding argument the default locale s encoding be use and so on window the grammar be read in in the wrong encoding and the lexer end up try to lex some mojibake however the lexicon say make sure to use the encoding option on the antlr tool if your grammar file be not in utf 8 format so that antlr read character properly this read to I like it be intend that the global default for grammar encoding be utf 8 so perhaps the documentation could be clarify a bit in this regard
antlrantlr4	feature parsing of binary stream instead of utf 8	Question	antlr should support the parsing of raw binary stream 1 byte per input character alongside utf 8 character have it available as an encoding for example antlr4 encode raw grammar g4 for example to match the byte 0x80 it be not possible right now as u0080 evaluate to 0xc280
antlrantlr4	link to plugin s web site be report as not find by maven linkcheck plugin	Bug	hello we use maven linkcheck plugin to check link on checkstyle s website the plugin report that on page the follow link be not find 404 link on plugin html be generate by apache maven project info report plugin all url be grab from effective pom of plugin here be the code l239 l269 in effective pom xml of maven antlr4 plugin the problematic link be as a result we do not have an ability to change plugin url on that page because those link be specify by plugin developer so please correct the link because there be contradiction between linkcheck and maven antlr4 plugin thank in advance

antlrantlr4	feature fix 4150 prevent invalid codegen in go	Bug	fix prevent the use of label start stop exception from generate bad go code close 4150 it might be good to prevent the use of label name that have an internal clash such as start text etc but that be not the case so this patch register start stop and exception as reserve name that must be suffix with it s still go to be a little confusing as on a rule the go code will have getstart which give the build in rule start get start which will return the label reference but this will prevent people raise error about code gen that be not really error
antlrantlr4	antlr 4 12 0 may produce java source with illegal unicode escape under window if a package name begin with u	Bug	this be a regression as 4 11 1 work correctly for file with a package start in u for instance it unibo xxx when use under window antlr 4 12 0 produce a header comment in the form generate from it unibo alchemist model internal biochemistry dsl biochemistrydsl g4 by antlr 4 12 0 this be problematic however as the java compiler report it as error illegal unicode escape here be a gradle scan show the issue quick reproduction can be achieve with the follow git clone cd alchemist git checkout renovate antlr4 gradlew alchemist incarnation biochemistry compilejava the fix should be reasonably easy I d suggest convert backslashe to slash in the header also this would generate the same comment code for all the platform

antlrantlr4	fix for issue 3319	Bug	this be a fix for which be relate to the problem report here issuecomment 951043189 the problem be in the go runtime specifically with atnconfigset s in august 2021 there be a commit for a new hash set implementation for set diff c8d23baf74aa15c0f0d472c90651ccd8755c5acd23dc452e1f42fa5d9d564907 which expose a bug in atnconfigset s that have exist for over 5 year it be only now reveal due to the confluence of that commit the huge test suite of antlr4 grammar in github com antlr grammar v4 now port to 6 or so target and a bug in the github action build for grammar v4 our lucky day the august 2021 commit implement the hash set as a two level hash table with probe the problem occur if one try to add an atnconfig to the table with a nil lexeractionexecutor field when the atnconfig s collide in the hash table this only happen when two state have equal state number module 16 the old code would get a segv at this line of code l167 the solution be to first cast other to othert and then test that it be nil prior to use I add code to test the bug in file atnconfigset test go with this change please read the comment in the file to see how to test
antlrantlr4	go target can not use superclass for the lexer grammar	Bug	I m try to use the superclass option in a lexer grammar it work fine for a parser grammar but for a lexer grammar it fail at runtime with a null pointer dereference in the generated constructor newfoobarlexer for example type csharplexer struct csharplexerbase channelname string modename string todo eof string func newcsharplexer input antlr charstream csharplexer l new csharplexer l baselexer antlr newbaselexer input crash here with null ptr deref return l it crash on l baselexer antlr newbaselexer input specifically on the assignment to l baselexer and not on the call to the constructor antlr newbaselexer input contrast this with the parser code type csharpparser struct csharpparserbase func newcsharpparser input antlr tokenstream csharpparser this new csharpparser this baseparser antlr newbaseparser input return this this code work for the parser the assignment to this baseparser work fine as it s not a null pointer the constructor code for the lexer fail because the type csharplexer struct be wrong it define the struct to contain csharplexerbase whereas in the parser type csharpparser struct the struct contain csharpparserbase not a pointer change the type struct declation for the generate lexer to csharplexerbase instead of csharplexerbase fix the crash and my parser lexer work just fine the problem be here csharplexerbase the line erroneously contain whereas for the parser here l180 it be declare directly
antlrantlr4	revert cpp target no building test sample for external utfcpp	Bug	revert antlr antlr4 3040 this seem to conflict more than expect with previous patch for utfcpp

generic segment tree min max range update bug

Bug

the generic segment tree implementation seem to be suffer from two issue when use multiplication range update with min max range query the segment tree doesn t seem to handle overflow well hard to avoid with multiplication update in general or at least the result doesn t match with the test value this may be because the segment tree only capture the min max value in a segment and when this value overflow the true min max be lose not sure how much can be do here perhaps just ensure no overflow can happen in the test update involve negative value aren t be handle I m not certain this can be handle with the current framework I think we may need to keep track of more information it may be worth investigate if a shadow min segment tree or a pair of value on the segment node can be useful for a max segment tree for this situation and vice versa when we encounter a negative value my idea be that for a max segment tree when a negative value be encounter the maximum value would become the minimum value in a min segment tree I don t know if this work but I think it s in the right direction java long ar 2 1 3 4 1 genericsegmenttree st new genericsegmenttree ar genericsegmenttree segmentcombinationfn max genericsegmenttree rangeupdatefn multiplication st rangeupdate1 0 4 1 assertthat st rangequery1 0 4 isequalto 4 negative number be a known issue st rangeupdate1 0 4 2 assertthat st rangequery1 0 4 isequalto 2 return 8 as max but should be 2

literal unicode symbol in grammar

Question

if I generate a lexer for the java target with a grammar that contain literal unicode symbol encode in utf 8 e g lexer grammar lex forall the generate lexer differ when generate on different platform linux window in this case as far as I understand this be because when you do not supply the encoding argument the default locale s encoding be use and so on window the grammar be read in in the wrong encoding and the lexer end up try to lex some mojibake however the lexicon say make sure to use the encoding option on the antlr tool if your grammar file be not in utf 8 format so that antlr read character properly this read to I like it be intend that the global default for grammar encoding be utf 8 so perhaps the documentation could be clarify a bit in this regard

javascript runtime bad field name bad comment

Bug

in this so question I take a look at the javascript runtime to see if buildparsetree be define for a parser indeed it be l40 but I notice there be one applied occurrence of the field erroneously spell buildparsetree l137 of course in the warped world of js this be not catch either by compiler or runtime also there be no getbuildparsetree note here l85 and here l120 I realize code review be old school but rely on a terrible programming language like javascript to find error be not go to work

cpp disable warning for external project

Bug

when add antlr as an external project the downstream user will generally not be interested in compiler warning emit for antlr itself as they win t be able to do anything about they anyway in their project thus this commit add a new cmake option disable warning that can be use to suppress compiler warning this flag be then subsequently set whenever antlr be use as an externalproject

fix for issue 3319

Bug

this be a fix for which be relate to the problem report here issuecomment 951043189 the problem be in the go runtime specifically with atnconfigset s in august 2021 there be a commit for a new hash set implementation for set diff c8d23baf74aa15c0f0d472c90651ccd8755c5acd23dc452e1f42fa5d9d564907 which expose a bug in atnconfigset s that have exist for over 5 year it be only now reveal due to the confluence of that commit the huge test suite of antlr4 grammar in github com antlr grammar v4 now port to 6 or so target and a bug in the github action build for grammar v4 our lucky day the august 2021 commit implement the hash set as a two level hash table with probe the problem occur if one try to add an atnconfig to the table with a nil lexeractionexecutor field when the atnconfig s collide in the hash table this only happen when two state have equal state number module 16 the old code would get a segv at this line of code l167 the solution be to first cast other to othert and then test that it be nil prior to use I add code to test the bug in file atnconfigset test go with this change please read the comment in the file to see how to test

go target can not use superclass for the lexer grammar

Bug

I m try to use the superclass option in a lexer grammar it work fine for a parser grammar but for a lexer grammar it fail at runtime with a null pointer dereference in the generated constructor newfoobarlexer for example type csharplexer struct csharplexerbase channelname string modename string todo eof string func newcsharplexer input antlr charstream csharplexer l new csharplexer l baselexer antlr newbaselexer input crash here with null ptr deref return l it crash on l baselexer antlr newbaselexer input specifically on the assignment to l baselexer and not on the call to the constructor antlr newbaselexer input contrast this with the parser code type csharpparser struct csharpparserbase func newcsharpparser input antlr tokenstream csharpparser this new csharpparser this baseparser antlr newbaseparser input return this this code work for the parser the assignment to this baseparser work fine as it s not a null pointer the constructor code for the lexer fail because the type csharplexer struct be wrong it define the struct to contain csharplexerbase whereas in the parser type csharpparser struct the struct contain csharpparserbase not a pointer change the type struct declation for the generate lexer to csharplexerbase instead of csharplexerbase fix the crash and my parser lexer work just fine the problem be here csharplexerbase the line erroneously contain whereas for the parser here l180 it be declare directly
