Subject: [PATCH 03/32] chore(lint): don't allow excess trailing newlines
 (#816)

* chore(lint): don't allow excess trailing newlines

This enforces that files should not end with blank lines (i.e. more than
one trailing newline). The `eol-last` rule (inherited from airbnb's
config) already enforces that files end in at least one trailing
newline, so adding this rule enforces that it ends in exactly 1.

See https://eslint.org/docs/rules/no-multiple-empty-lines and
https://eslint.org/docs/rules/eol-last for more information.

Inspired by #809.

Subject: [PATCH 04/32] Remove separate "internal error" from exec (#802)

* Remove separate "internal error" from exec

* Fix unknown command error regex

* Add message about command not found regex

* Silence errors while reading files in exec

The stdout and stderr files may never be opened or written to in certain
circumstances. In particular, if the timeout is short enough, the child
node process does not have enough time to start, and the child script
does not execute, so the files are not written to. So, catch errors form
trying to read the files, and ignore them.

* Do not silence errors due to short timeouts

* Simplify test regex for missing command

* Default error code to 1 if not set

Subject: [PATCH 11/32] chore(appveyor): do not use latest npm (#847)

This changes appveyor from using the latest npm version to only using
the preinstalled npm version. This is safer, because it's guaranteed to
be a compatible version.

Fixes #844

Subject: [PATCH 12/32] chore: output npm version in travis (#850)

Knowing the `npm` version was a huge help to debugging issue #844. For
some reason, we output this on appveyor but not on Travis. This PR fixes
that.

Subject: [PATCH 14/32] chore: bump dev dependencies and add package-lock
 (#864)

No change to logic.

This reduces install spam by bumping codecov to avoid depending on a
deprecated graceful-fs version, as well as adding a package-lock.json.

Subject: [PATCH 15/32] fix(mocks): fix conflict between mocks and skip (#863)

This fixes a conflict between mocks.init() and
utils.skipOnWin/skipOnUnix. mocks.init() mocks out process.stderr.write,
which utils.js implicitly depends on.

Instead, preserve stderr.write in a local variable to avoid polluting
mocked stdio and to correctly output warning messages.

Fixes #862
Test: locally apply mocks.init() inside test/which.js

Subject: [PATCH 16/32] Fix cp from readonly source (#870)

This is a redo of PR #555.

This rebases, cleans up a test, and fixes a bug (the original PR uses `fs.chown()` instead of `fs.chownSync()`).

Fixes #98

Subject: [PATCH 18/32] Fix(which): match only executable files (#874)

On Unix, this only matches files with the exec bit set. On Windows, this only
matches files which are readable (since Windows has different rules for
execution).

Fixes #657.

Subject: [PATCH 20/32] docs: remove gitter badge (#880)

No change to logic.

We don't really use the gitter chatroom right now, so we shouldn't
direct users to chat there. It's best to have issues reported directly
on Github.

This PR removes the gitter badge from the README.

No change to logic.

This changes appveyor to run the entire test matrix, even if a failure
occurs early on. This is helpful for debugging.

Subject: [PATCH 22/32] chore(npm): add ci-or-install script (#896)

* chore(npm): add ci-or-install script

This adds a script which checks the npm version and runs either `npm ci`
or `npm install` based on support. This is primarily to work around an
issue where `npm install` modifies `package-lock.json` for newer npm
versions.

A side benefit is that `npm ci` is slightly faster than `npm install`.

Fixes #893

Subject: [PATCH 23/32] fix: silent exec (#892)

Unconditionally apply `silent: true` when calling `common.error()` from
`exec()`. This is because errors are already printed to stderr, or are
intentionally silenced by `shell.config.silent`.

Based on #861

Fixes #851

Subject: [PATCH 25/32] refactor: don't expose tempdir in common.state (#903)

Previously, the cached `tempdir` value was stored in `common.state`.
Unlike the other `common.state` values, this isn't immediately useful to
other commands (they can just call the tempdir API). So, this moves the
cached value into `tempdir.js`.

This also adds a unit test for the caching behavior, and exposes
test-only helpers to verify this behavior.

Finally, this adds a note to `common.state` that values should generally
be considered read-only, since this can be important for customized
behavior. Although, I recognize our code base has one exception to this
rule (`echo()`), we should strive to maintain this.

Fixes #902
Test: Added a unit test.

Subject: [PATCH 29/32] Silence potentially upcoming circular dependency
 warning (#973)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Node.js is currently considering printing a warning when a non-existent
property of `module.exports` is accessed while in a circular `require()`
dependency, in order to make it easier to catch issues with circular
dependencies.

In order to avoid printing these warnings for shelljs, checking for the
property’s existence rather than its truthiness suffices.
