When rclone received a SIGINT (Ctrl+C) or SIGTERM signal while an atexit
function is registered it always terminated with status code 0. Unix
convention is to exit with a non-zero status code. Often it's
`128 + int(signum), but at least not zero.
With this change fatal signals handled by the `atexit` package cause
a non-zero exit code. On Unix systems it's `128 + int(signum)` while
on other systems, such as Windows, it's always 2 ("error not otherwise
categorised").
Resolves#5437.

Signal handling by the `atexit` package needs acceess to
`exitCodeUncategorizedError`. With this change all exit status values
are moved to a dedicated package so that they can be reused.

Currently rclone check supports matching two file trees by sizes and hashes.
This change adds support for SUM files produced by GNU utilities like sha1sum.
Fixes#1005
Note: checksum by default checks, hashsum by default prints sums.
New flag is named "--checkfile" but carries hash name.
Summary of introduced command forms:
```
rclone check sums.sha1 remote:path --checkfile sha1
rclone checksum sha1 sums.sha1 remote:path
rclone hashsum sha1 remote:path --checkfile sums.sha1
rclone sha1sum remote:path --checkfile sums.sha1
rclone md5sum remote:path --checkfile sums.md5
```
This change fixes the bug described below:
if a file is removed while the local backend List() runs,
the call will flag an accounting error.
The bug manifests itself if local backend is the Sync target
due to intrinsic concurrency.
The odds to hit this bug depend on --checkers and --transfers.
Chunker over local backend is affected even more because
updating a composite object with a smaller size content
translates into removing chunks on the underlying file system
and involves a number of List() calls.
There was no easy way to automatically test the end-to-end functionality
of commands, flags, environment variables etc.
The need for end-to-end testing was highlighted by the issues fixed
in #5341. There was no automated test to continually verify current
behaviour, nor a framework to quickly test the correctness of the fixes.
This change adds an end-to-end testing framework in the cmdtest folder.
It has some simple examples in func TestCmdTest in cmdtest_test.go. The
tests should be readable by anybody familiar with rclone and look like
this:
// Test the rclone version command with debug logging (-vv)
out, err = rclone("version", "-vv")
if assert.NoError(t, err) {
assert.Contains(t, out, "rclone v")
assert.Contains(t, out, "os/version:")
assert.Contains(t, out, " DEBUG : ")
}
The end-to-end tests are executed just like the Go unit tests, that is:
go test ./cmdtest -v
The change also contains a thorough test of environment variables in
environment_test.go.
Thanks to @ncw for encouragement and introduction to the TestMain trick.
Some environment variables didn’t behave like their corresponding
command line flags. The affected flags were --stats, --log-level,
--separator, --multi-tread-streams, --rc-addr, --rc-user and --rc-pass.
Example:
RCLONE_STATS='10s'
rclone check remote: remote: --progress
# Expected: rclone check remote: remote: --progress –-stats=10s
# Actual: rclone check remote: remote: --progress
Remote specific options set by environment variables was overruled by
less specific backend options set by environment variables. Example:
RCLONE_DRIVE_USE_TRASH='false'
RCLONE_CONFIG_MYDRIVE_USE_TRASH='true'
rclone deletefile myDrive:my-test-file
# Expected: my-test-file is recoverable in the trash folder
# Actual: my-test-file is permanently deleted (not recoverable)
Backend specific options set by environment variables was overruled by
general backend options set by environment variables. Example:
RCLONE_SKIP_LINKS='true'
RCLONE_LOCAL_SKIP_LINKS='false'
rclone lsd local:
# Expected result: Warnings when symlinks are skipped
# Actual result: No warnings when symlinks are skipped
# That is RCLONE_SKIP_LINKS takes precedence
The above issues have been fixed.
The debug logging (-vv) has been enhanced to show when flags are set by
environment variables.
The documentation has been enhanced with details on the precedence of
configuration options.

Improved/added steps to:
* Install Git with basic setup
* Use both SSH and HTTPS for the git origin
* Install Go and verify the GOPATH
* Update the forked master
* Find a popular editor for Go
Nothing is added or removed and no package is renamed by this change.
Just rearrange definitions between source files in the fs directory.
New source files:
- types.go Filesystem types and interfaces
- features.go Features and optional interfaces
- registry.go Filesystem registry and backend options
- newfs.go NewFs and its helpers
- configmap.go Getters and Setters for ConfigMap
- pacer.go Pacer with logging and calculator
The final fs.go contains what is left.
Also rename options.go to open_options.go
to dissociate from registry options.
