Commit 8d3d28f5 added test cases for URLs which should be ssh.
Add more tests testing all the combinations:
-IPv4 or IPv6
-path starting with "/" or with "/~"
-with and without the ssh:// scheme
Add tests for ssh:// with port number.
When a git repository "foo:bar" exist, git clone will call
absolute_path() and git_connect() will be called with
something like "/home/user/projects/foo:bar"
Tighten the test and use "foo:bar" instead of "./foo:bar",
refactor clear_ssh() and expect_ssh() into test_clone_url().
"git clone foo/bar:baz" should not be ssh:
Make the rule
"if there is a slash before the first colon, it is not ssh"
more strict by using the same is_local() in both connect.c
and transport.c. Add a test case.
Bug fixes for corner cases:
- Handle clone of [::1]:/~repo correctly (2e7766655):
Git should call "ssh ::1 ~repo", not ssh ::1 /~repo
This was caused by looking at (host != url), which never
worked for host names with literal IPv6 adresses, embedded by []
Support for the [] URLs was introduced in 356bece0a.
- Do not tamper local URLs starting with '[' which have a ']'
Bug fix for msygit in t5601 : use $PWD insted of $(pwd)
Helped-by: Jeff King <peff@xxxxxxxx>
Signed-off-by: Torsten Bögershausen <tboegi@xxxxxx>
---
Changes since V3:
- Integrated Peffs suggestions in t5601
(Remove clear_ssh)
- Decide early if it is ssl or local in connect.c
- Use "git fetch" instead of "git clone" in t5601:
clone use absolute_path() (adding a / before :), fetch does not
- Add a test for dos_drive "C:temp" for msys
- Make tests work for msys by using $PWD instead of $(pwd) (file://$PWD)
