As unix cp command complains when you copy a directory into itself,
(such as `cp -r ~/Desktop/ ~/Desktop/sub/`), mc will follow the
same behavior with this commit.
The main reason is that copy or mirror command can be unpredictable
with the style of copy.
Example:
```
$ mc ls -r myminio/testbucket/
[2018-09-25 19:28:17 CET] 8B dir/object
[2018-09-25 19:28:40 CET] 8B object
$ mc -q cp -r myminio/testbucket/ myminio/testbucket/dir/
`myminio/testbucket/dir/object` -> `myminio/testbucket/dir/dir/object`
`myminio/testbucket/object` -> `myminio/testbucket/dir/object`
```
We can notice that `myminio/testbucket/dir/object` is both source and target
in the copy operation. The last copy operation that will occur will rule the
result of the total copy operation and `myminio/testbucket/dir/dir/object`
will have a different content in each copy operation.
Due to the unpredictability mentionned above, we will disallow copying or
mirroring a folder into itself.
Currently even if the command supports encrypted objects,
the syntax verification would fail on them in certain
cases. Since syntax validation of source/targets doesn't
use the parsed encrypt key pairs. This PR fixes this
behavior.
If we have any listing problem, we should stop comparing difference
between source & target lists because it is already so hard to know
what mc should do next. So, let's inform users and let them deal
with the problem.
mc used to show a warning messages during mirroring when it
detects a need to overwrite or remove a remote object but no
flag is specified. This commit efeaf2ee72
changed this behavior but this commit will restablish
the old behavior.
Added exclude options to exclude unwanted system files.
Exclude option excludes the source files/objects that match
the passed shell file name pattern
Fixes#1903
Currently `mc mirror` requires source to be
uploaded only if the size is different than the
object on remote server. This PR adds support to
check for last modified time of the source object
as well such that we upload if there are timestamp
differences as well.
Fixes#2187
This fixes#1889.
```sh
mc mirror -w
```
Now runs continous even when the source is not available.
Reconnects indefinitely in a binomially increasing fashion
and also allows jitter so that the retry has a nice
distribution as well.
This allows for 'mc mirror -w' to run continously without
further monitoring.
