Unexpected handling of lines with less than 100 characters

Tái hiện vấn đề với test.java bằng cách sử dụng lệnh gọi dòng lệnh google-java-format-1.9-all-deps.jar được nêu trong báo cáo, đồng thời so sánh đầu ra trước, sau và đầu ra mong đợi. Theo dõi hành vi của formatter đối với các chuỗi SQL nhiều dòng; công việc được xem là hoàn tất khi chỉ dòng quá dài được tách ra, còn các dòng ngắn hơn khác vẫn giữ nguyên định dạng ban đầu.

I have some quite large sql multiline string and when one line is over 100 characters it will re-format it onto 2 lines. While I believe this is the correct behaviour to split this long line, it also re-formats all of the other lines of the String which I don't think should happen as they are under 100 characters long, therefore I think this is a bug.

NB: Because of https://github.com/google/google-java-format/issues/566 you can only see this happening using the jar on the command line as per the example below:

before - unformatted file:

package x;

public class test {

  static final String MY_SQL_QUERY =
      "SELECT "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  l.some_really_long_column_name    AS some_really_looooooooooooooooooooong_column_name, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, ";

  public test() {
    int x=1;if(x==1){x=2;}else{x=3;}
  }

}

apply google java formatting:

/tmp $ java -version
openjdk version "11.0.9" 2020-10-20
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.9+11)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.9+11, mixed mode)
/tmp $ cksum ~/lib/google-java-format-1.9-all-deps.jar

/tmp $ java -jar ~/lib/google-java-format-1.9-all-deps.jar ./test.java

after - formatted by google java formatter:

package x;

public class test {

  static final String MY_SQL_QUERY =
      "SELECT   customer_id             AS customer_id,   customer_id             AS customer_id, "
          + "  customer_id             AS customer_id,   customer_id             AS customer_id,  "
          + " customer_id             AS customer_id,   l.some_really_long_column_name    AS"
          + " some_really_looooooooooooooooooooong_column_name,   customer_id             AS"
          + " customer_id,   customer_id             AS customer_id, ";

  public test() {
    int x = 1;
    if (x == 1) {
      x = 2;
    } else {
      x = 3;
    }
  }
}

Expected - this is what I think google java formatter should do:

package x;

public class test {

  static final String MY_SQL_QUERY =
      "SELECT "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  l.some_really_long_column_name    "
                 + "AS some_really_looooooooooooooooooooong_column_name, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, ";

  public test() {
    int x = 1;
    if (x == 1) {
      x = 2;
    } else {
      x = 3;
    }
  }
}
