   1# Shell library to run an HTTP server for use in tests.
   2# Ends the test early if httpd tests should not be run,
   3# for example because the user has not enabled them.
   4#
   5# Usage:
   6#
   7#       . ./test-lib.sh
   8#       . "$TEST_DIRECTORY"/lib-httpd.sh
   9#       start_httpd
  10#
  11#       test_expect_success '...' '
  12#               ...
  13#       '
  14#
  15#       test_expect_success ...
  16#
  17#       stop_httpd
  18#       test_done
  19#
  20# Can be configured using the following variables.
  21#
  22#    GIT_TEST_HTTPD              enable HTTPD tests
  23#    LIB_HTTPD_PATH              web server path
  24#    LIB_HTTPD_MODULE_PATH       web server modules path
  25#    LIB_HTTPD_PORT              listening port
  26#    LIB_HTTPD_DAV               enable DAV
  27#    LIB_HTTPD_SVN               enable SVN at given location (e.g. "svn")
  28#    LIB_HTTPD_SSL               enable SSL
