Duy Nguyen	a97262c62f	diff: make -O and --output work in subdirectory Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	9 years ago
Kirill Smelkov	91921ceff6	diff test: add tests for combine-diff with orderfile In the next patch combine-diff will have special code-path for taking orderfile into account. Prepare for making changes by introducing coverage tests for that case. Signed-off-by: Kirill Smelkov <kirr@mns.spb.ru> Signed-off-by: Junio C Hamano <gitster@pobox.com>	11 years ago
Jonathan Nieder	0df49bef95	diff test: reading a directory as a file need not error out There is no guarantee that strbuf_read_file must error out for directories. On some operating systems (e.g., Debian GNU/kFreeBSD wheezy), reading a directory gives its raw content: $ head -c5 < / \| cat -A ^AM-\|^_^@^L$ As a result, 'git diff -O/' succeeds instead of erroring out on these systems, causing t4056.5 "orderfile is a directory" to fail. On some weird OS it might even make sense to pass a directory to the -O option and this is not a common user mistake that needs catching. Remove the test.

Samuel Bronson	6d8940b562	diff: add diff.orderfile configuration variable diff.orderfile acts as a default for the -O command line option. [sb: split up aw's original patch; rework tests and docs, treat option as pathname] Signed-off-by: Anders Waldenborg <anders@0x63.nu> Signed-off-by: Samuel Bronson <naesten@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	11 years ago
Samuel Bronson	a21bae33d9	diff: let "git diff -O" read orderfile from any file and fail properly The -O flag really shouldn't silently fail to do anything when given a path that it can't read from. However, it should be able to read from un-mmappable files, such as: * pipes/fifos * /dev/null: It's a character device (at least on Linux) * ANY empty file: Quoting Linux mmap(2), "SUSv3 specifies that mmap() should fail if length is 0. However, in kernels before 2.6.12, mmap() succeeded in this case: no mapping was created and the call returned addr. Since kernel 2.6.12, mmap() fails with the error EINVAL for this case." We especially want "-O/dev/null" to work, since we will be documenting it as the way to cancel "diff.orderfile" when we add that. (Note: "-O/dev/null" did have the right effect, since the existing error handling essentially worked out to "silently ignore the orderfile". But this was probably more coincidence than anything else.) So, lets toss all of that logic to get the file mmapped and just use strbuf_read_file() instead, which gives us decent error handling practically for free.
