changing `.java` files.

 * **Kotlin source compatibility** is the ability to upgrade Kotlin uses of OkHttp 3.x to 4.x
   without changing `.kt` files.

With a few small exceptions (below), OkHttp 4.x is both binary- and Java source-compatible with
OkHttp 3.x. You can use an OkHttp 4.x .jar file with applications or libraries built for OkHttp 3.x.

Environment variables could be useful for handling application **settings**, as part of the **installation** of Python, etc.

## Create and Use Env Vars { #create-and-use-env-vars }

You can **create** and use environment variables in the **shell (terminal)**, without needing Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// You could create an env var MY_NAME with
$ export MY_NAME="Wade Wilson"

     * @return retry delay or 0 if no retry

    public long getRetryDelay() {
        switch (severity) {
        case RECOVERABLE:
            return 100; // Immediate retry with small delay
        case TRANSIENT:
            return 5000; // Wait 5 seconds
        default:
            return 0; // No retry
        }
    }

    @Override
    public String toString() {

        bufferIndex += 4;

        // Validate remaining buffer size for algorithms
        if (len < 8 + (compressionCount * 2)) {
            throw new SMBProtocolDecodingException("Buffer too small for compression algorithms");
        }

        // Read compression algorithms
        this.compressionAlgorithms = new int[compressionCount];
        for (int i = 0; i < compressionCount; i++) {

	stmt := dryRunDB.Where(
		DB.Where("pizza = ?", "pepperoni").Where(DB.Where("size = ?", "small").Or("size = ?", "medium")),
	).Or(
		DB.Where("pizza = ?", "hawaiian").Where("size = ?", "xlarge"),
	).Find(&Pizza{}).Statement

	execStmt := dryRunDB.Exec("WHERE (pizza = ? AND (size = ? OR size = ?)) OR (pizza = ? AND size = ?)", "pepperoni", "small", "medium", "hawaiian", "xlarge").Statement

For example:
```shell
group_search_filter: (&(objectClass=group)(member:1.2.840.113556.1.4.1941:=%d))
user_dn_search_filter: (&(memberOf:1.2.840.113556.1.4.1941:=CN=group,DC=dc,DC=net)(sAMAccountName=%s))
```

### Sample settings

Here are some (minimal) sample settings for development or experimentation:

```shell
export MINIO_IDENTITY_LDAP_SERVER_ADDR=myldapserver.com:636

        data[7] = (byte) (high >> 24);

        PacDataInputStream pdis = createInputStream(data);
        Date date = pdis.readFiletime();
        assertNotNull(date);
        // Allow for a small difference due to precision loss
        assertEquals(time / 1000, date.getTime() / 1000);

        // Test with null date (0x7fffffff ffffffff)

  alias realpath=grealpath
  alias stat=gstat
  # By default, aliases are only expanded in interactive shells, which means
  # that they are not substituted for their corresponding commands in shell
  # scripts. By setting "expand_aliases", we enable alias expansion in
  # non-interactive shells as well.
  shopt -s expand_aliases
else
  echo '==TFCI==: Error: Cannot find path to grealpath or gstat'

        long[][] timeValues = { { 0L, 0L, 0L, 0L }, // All zeros
                { Long.MAX_VALUE, Long.MAX_VALUE, Long.MAX_VALUE, Long.MAX_VALUE }, // Max values
                { 1L, 2L, 3L, 4L }, // Small values
                { -1L, -2L, -3L, -4L } // Negative values (though unusual for file times)
        };

        for (long[] times : timeValues) {
            // Given
