PHP 8.5.0RC1 the stream_isatty test failed when running the tests.

[ArchMaster2024]

Description

The following code:

require __DIR__.'/stream_isatty.inc';
testToStdErr();
<?php

Resulted in this output:

STDIN (constant): bool(false)
STDIN (fopen): bool(false)
STDIN (php://fd/0): bool(false)
STDOUT (constant): bool(false)
STDOUT (fopen): bool(false)
STDOUT (php://fd/1): bool(false)
STDERR (constant): bool(false)
STDERR (fopen): bool(false)
STDERR (php://fd/2): bool(false)
Invalid stream (php://temp): bool(false)
Invalid stream (php://input): bool(false)
Invalid stream (php://memory): bool(false)
File stream: bool(false)

But I expected this output instead:

STDIN (constant): bool(true)
STDIN (fopen): bool(true)
STDIN (php://fd/0): bool(true)
STDOUT (constant): bool(true)
STDOUT (fopen): bool(true)
STDOUT (php://fd/1): bool(true)
STDERR (constant): bool(false)
STDERR (fopen): bool(false)
STDERR (php://fd/2): bool(false)
Invalid stream (php://temp): bool(false)
Invalid stream (php://input): bool(false)
Invalid stream (php://memory): bool(false)
File stream: bool(false)

It should be noted that there were other errors, but they are really the same at the level of the file logic, but the error is exactly the same, so I am not going to report it.

[ArchMaster2024]

However, I'll indicate which specific files are throwing the error:

1. Test stream_isatty with redirected STDERR [tests/output/stream_isatty_err.phpt] (This is the one I reported)
2. Test stream_isatty with redirected STDIN/STDERR [tests/output/stream_isatty_in-err.phpt]
3. Test stream_isatty with redirected STDIN/STDOUT [tests/output/stream_isatty_in-out.phpt]
4. Test stream_isatty with redirected STDOUT/STDERR [tests/output/stream_isatty_out-err.phpt]
5. Test stream_isatty with redirected STDOUT [tests/output/stream_isatty_out.phpt]

How are you running the tests? Are you actually running it from the terminal rather as part of a script? If it's the latter, you can set the SKIP_IO_CAPTURE_TESTS=1 environment variable.

[ArchMaster2024]

I running the tests with this command: make TEST_PHP_ARGS=-j4 test

[iluuu1994]

Can you elaborate a bit more? You mention it's a container, do you run it by connecting to the container through bash, or as part of the entrypoint/cmd?

[ArchMaster2024]

I run this command with bash script and RUN directive of Dockerfile.

I share the bash script and Dockerfile I use.

Dockerfile:

COPY . .

RUN chmod +x prepare_workspace.sh &&

Bash script:

#!/bin/bash

tar -xvjf php-8.5.0RC1.tar.bz2 # Decompress the file
cd php-8.5.0RC1 # Enter the directory
./buildconf # Generate the configure script
./configure # Configure
