ParseBanWords returned banwordall.xml mixed in with banword.xml, because it matched every file name containing "banword". The client treats the two lists differently: a banword.xml entry refuses any text that contains it, while a banwordall.xml entry refuses only a whole space-delimited word. Merged into one list, the server cannot tell them apart, so nig from banwordall.xml refuses "Good night", "Knight" and "Midnight". This splits the two files into separate methods and bumps the package to 2.4.35.

Needed by MS2Community/PrivateMaple2#1897.

Changes

  • Maple2.File.Parser/BanWordParser.cs: ParseBanWords now returns banword.xml only, and the new ParseBanWordAll returns banwordall.xml. Together they return the same words as before. All three methods share one private Parse. This changes what ParseBanWords returns, so a consumer that wants both lists must now call both methods.
  • Maple2.File.Parser/Maple2.File.Parser.csproj: 2.4.35.
  • Maple2.File.Tests/BanWordParserTest.cs: the pinned 6179 is now the sum of the two methods. It also checks that nazi, from banword.xml, comes only from ParseBanWords, and nig, from banwordall.xml in every locale that has it, comes only from ParseBanWordAll.

The client side, read in the KMS2 source: CBanTextChecker loads banWord.xml and banWordAll.xml into separate filters. FindBanWord matches a substring, and FindBanWordAll at 0x1402290b0 matches only a whole space-delimited word.

Verification

I have not run BanWordParserTest itself, since the test harness needs a .env I did not create. I ran the same calls from a small console program against packed MapleStory2-XML data instead: ParseBanWords 6420, ParseBanWordAll 1351, ParseUgcBanWords 1570. Those match a count of non-empty name attributes taken directly from the XML files. nazi and nig landed in the lists above. The 6179 sum in the test is from the data the test was written against, which I don't have.

PrivateMaple2 against a local build of this package: its whole-word ban word tests pass, and in game "Good night" and "Midnight" pass the ban word check while "I am a Nazi" is still refused.

Summary by CodeRabbit

  • Improvements
    • Ban-word data is now organized into separate general and “all” lists, with entries filtered and counted separately.
    • Existing user-generated content ban-word filtering remains unchanged.

ParseBanWords matched every file name containing "banword", so it
returned banwordall.xml's words mixed in with banword.xml's. The client
treats them differently: CBanTextChecker::FindBanWord refuses text that
contains a banword.xml entry, while FindBanWordAll, KMS2 0x1402290b0,
refuses a banwordall.xml entry only as a whole space-delimited word.
Mixed into one list, "nig" from banwordall.xml blocks "Good night".

ParseBanWords now returns banword.xml only, and ParseBanWordAll returns
banwordall.xml. Together they return the same words as before.

Walkthrough

The parser now separates banwordall files from other ban word files and uses shared parsing logic. Tests check the combined result count and confirm that selected words appear in the expected result.

Changes: Ban word parsing

Layer / File(s) Summary
Separate ban word file selection
Maple2.File.Parser/BanWordParser.cs
ParseBanWords excludes banwordall files. The new ParseBanWordAll method selects those files. Both methods and ParseUgcBanWords use shared parsing logic.
Validate parser results
Maple2.File.Tests/BanWordParserTest.cs, Maple2.File.Parser/Maple2.File.Parser.csproj
The test checks that both parser results total 6179 entries and that "nazi" and "nig" appear in their respective results. The parser package version changes from 2.4.34 to 2.4.35.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Suggested reviewers: zintixx

Merge Risk: Low · up to daeea

The parser split has no established functional defect. The remaining concern is a nonblocking test-coverage improvement: only two words verify list membership. Mergeable with follow-up awareness.

Explanation

Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 2 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Nitpick Compare each parser result with its source file in TestBanWordParser.

25-30: Trivial · Maintainability & Code Quality · Low value

Compare each parser result with its source file in TestBanWordParser.

The sum and the two sentinel checks do not verify the other entries. A regression that swaps other entries between ParseBanWords and ParseBanWordAll keeps the count and both sentinels, so the test still passes. The current selection works per file, so this is a coverage improvement, not a current defect.

Update TestBanWordParser to compare each complete parser result against the
entries in its corresponding source file, so swaps of non-sentinel entries
between ParseBanWords and ParseBanWordAll are detected; retain the existing
count and sentinel checks if they provide useful coverage.
