Peter Wu 87a3a924ce tests/http_pipe.py: Python 3 support
The 2to3 tool converted socketserver (which I manually fixed up with an
import fallback) and the print(e) line. The xrange option was converted
to range, but it seems better to use the '*' operator here for
simplicity.

==============================================================================

1. Running

 1.1 Requires to run

  perl (and a unix-style shell)
  python (and a unix-style shell)
  diff (when a test fails, a diff is shown)
  stunnel (for HTTPS and FTPS tests)
  OpenSSH or SunSSH (for SCP, SFTP and SOCKS4/5 tests)

 1.2 Port numbers used by test servers

  - TCP/8990 for HTTP
  - TCP/8991 for HTTPS
  - TCP/8992 for FTP
  - TCP/8993 for FTPS
  - TCP/8994 for HTTP IPv6
  - TCP/8995 for FTP (2)
  - TCP/8996 for FTP IPv6
  - UDP/8997 for TFTP
  - UDP/8998 for TFTP IPv6
  - TCP/8999 for SCP/SFTP
  - TCP/9000 for SOCKS
  - TCP/9001 for POP3
  - TCP/9002 for IMAP
  - TCP/9003 for SMTP
  - TCP/9004 for SMTP IPv6
  - TCP/9005 for RTSP
  - TCP/9006 for RTSP IPv6
  - TCP/9007 for GOPHER
  - TCP/9008 for GOPHER IPv6
  - TCP/9008 for HTTPS server with TLS-SRP support

 1.3 Test servers

  The test suite runs simple FTP, POP3, IMAP, SMTP, HTTP and TFTP stand-alone
  servers on the ports listed above to which it makes requests. For SSL tests,
  it runs stunnel to handle encryption to the regular servers. For SSH, it
  runs a standard OpenSSH server. For SOCKS4/5 tests SSH is used to perform
  the SOCKS functionality and requires a SSH client and server.

  The base port number (8990), which all the individual port numbers are
  indexed from, can be set explicitly using runtests.pl' -b option to allow
  running more than one instance of the test suite simultaneously on one
  machine, or just move the servers in case you have local services on any of
  those ports.

 1.4 Run

  'make test'. This builds the test suite support code and invokes the
  'runtests.pl' perl script to run all the tests. Edit the top variables
  of that script in case you have some specific needs, or run the script
  manually (after the support code has been built).

  The script breaks on the first test that doesn't do OK. Use -a to prevent
  the script from aborting on the first error. Run the script with -v for more
  verbose output. Use -d to run the test servers with debug output enabled as
  well. Specifying -k keeps all the log files generated by the test intact.

  Use -s for shorter output, or pass test numbers to run specific tests only
  (like "./runtests.pl 3 4" to test 3 and 4 only). It also supports test case
  ranges with 'to', as in "./runtests 3 to 9" which runs the seven tests from
  3 to 9. Any test numbers starting with ! are disabled, as are any test
  numbers found in the file data/DISABLED (one per line).

  When -s is not present, each successful test will display on one line the
  test number and description and on the next line a set of flags, the test
  result, current test sequence, total number of tests to be run and an
  estimated amount of time to complete the test run. The flags consist of
  these letters describing what is checked in this test:

    s stdout
    d data
    u upload
    p protocol
    o output
    e exit code
    m memory
    v valgrind

 1.5 Shell startup scripts

  Tests which use the ssh test server, SCP/SFTP/SOCKS tests, might be badly
  influenced by the output of system wide or user specific shell startup
  scripts, .bashrc, .profile, /etc/csh.cshrc, .login, /etc/bashrc, etc. which
  output text messages or escape sequences on user login.  When these shell
  startup messages or escape sequences are output they might corrupt the
  expected stream of data which flows to the sftp-server or from the ssh
  client which can result in bad test behaviour or even prevent the test
  server from running.

  If the test suite ssh or sftp server fails to start up and logs the message
  'Received message too long' then you are certainly suffering the unwanted
  output of a shell startup script.  Locate, cleanup or adjust the shell
  script.

 1.6 Memory test

  The test script will check that all allocated memory is freed properly IF
  curl has been built with the CURLDEBUG define set. The script will
  automatically detect if that is the case, and it will use the
  'memanalyze.pl' script to analyze the memory debugging output.

  Also, if you run tests on a machine where valgrind is found, the script will
  use valgrind to run the test with (unless you use -n) to further verify
  correctness.

  runtests.pl's -t option will enable torture testing mode, which runs each
  test many times and makes each different memory allocation fail on each
  successive run.  This tests the out of memory error handling code to ensure
  that memory leaks do not occur even in those situations. It can help to
  compile curl with CPPFLAGS=-DMEMDEBUG_LOG_SYNC when using this option, to
  ensure that the memory log file is properly written even if curl crashes.

 1.7 Debug

  If a test case fails, you can conveniently get the script to invoke the
  debugger (gdb) for you with the server running and the exact same command
  line parameters that failed. Just invoke 'runtests.pl <test number> -g' and
  then just type 'run' in the debugger to perform the command through the
  debugger.

 1.8 Logs

  All logs are generated in the logs/ subdirectory (it is emptied first in the
  runtests.pl script). Use runtests.pl -k to force it to keep the temporary
  files after the test run since successful runs will clean it up otherwise.

 1.9 Test input files

  All test cases are put in the data/ subdirectory. Each test is stored in the
  file named according to the test number.

  See FILEFORMAT for the description of the test case files.

 1.10 Code coverage

  gcc provides a tool that can determine the code coverage figures for
  the test suite.  To use it, configure curl with
  CFLAGS='-fprofile-arcs -ftest-coverage -g -O0'.  Make sure you run the normal
  and torture tests to get more full coverage, i.e. do:

    make test
    make test-torture

  The graphical tool ggcov can be used to browse the source and create
  coverage reports on *NIX hosts:

    ggcov -r lib src

  The text mode tool gcov may also be used, but it doesn't handle object files
  in more than one directory very well.

 1.11 Remote testing

  The runtests.pl script provides some hooks to allow curl to be tested on a
  machine where perl can not be run.  The test framework in this case runs on
  a workstation where perl is available, while curl itself is run on a remote
  system using ssh or some other remote execution method.  See the comments at
  the beginning of runtests.pl for details.

2. Numbering

 2.1 Test case numbering

     1   -  99   HTTP
     100 - 199   FTP*
     200 - 299   FILE*
     300 - 399   HTTPS
     400 - 499   FTPS
     500 - 599   libcurl source code tests, not using the curl command tool
     600 - 699   SCP/SFTP
     700 - 799   SOCKS4 (even numbers) and SOCK5 (odd numbers)
     800 - 899   POP3, IMAP, SMTP
     1000 - 1299 miscellaneous*
     1300 - 1399 unit tests*
     1400 - 1499 miscellaneous*
     1500 - 1599 libcurl source code tests, not using the curl command tool
                 (same as 5xx)
     2000 - x    multiple sequential protocols per test case*

  Since 30-apr-2003, there's nothing in the system that requires us to keep
  within these number series, and those sections marked with * actually
  contain tests for a variety of protocols. Each test case now specifies its
  own server requirements, independent of test number.

3. Write tests

  Here's a quick description on writing test cases. We basically have three
  kinds of tests: the ones that test the curl tool, the ones that build small
  applications and test libcurl directly and the unit tests that test
  individual (possibly internal) functions.

 3.1 test data

  Each test has a master file that controls all the test data. What to read,
  what the protocol exchange should look like, what exit code to expect and
  what command line arguments to use etc.

  These files are tests/data/test[num] where [num] is described in section 2
  of this document, and the XML-like file format of them is described in the
  separate tests/FILEFORMAT document.

 3.2 curl tests

  A test case that runs the curl tool and verifies that it gets the correct
  data, it sends the correct data, it uses the correct protocol primitives
  etc.

 3.3 libcurl tests

  The libcurl tests are identical to the curl ones, except that they use a
  specific and dedicated custom-built program to run instead of "curl". This
  tool is built from source code placed in tests/libtest and if you want to
  make a new libcurl test that is where you add your code.

 3.4 unit tests

  Unit tests are tests in the 13xx sequence and they are placed in tests/unit.
  There's a tests/unit/README describing the specific set of checks and macros
  that may be used when writing tests that verify behaviors of specific
  individual functions.

  The unit tests depend on curl being built with debug enabled.

4. TODO

 4.1 More protocols

  Add tests for TELNET, LDAP, DICT...

 4.2 SOCKS auth

  SOCKS4/5 test deficiencies - no proxy authentication tests as SSH (the
  test mechanism) doesn't support them
