Multi account support | Fix #98

[Akianonymus]

Add four new flags

• -a | --account - Use a different account than default

• -la | --list accounts - List all the accounts configured with CLIENT_ID, CLIENT_SECRET and REFRESH_TOKEN

• -ca | --create-account - Create a new account

• -da | --delete-account - Delete an existing account

--list-accounts, --create-accounts and --delete-account flags can be used without any usual input required

The config format is changed, ACCOUNT_${account}_ prefix is added to every config var, where ${account} is the account name

The old configs will be automatically migrated with account name default( if default taken then a number suffix will be added like default1, default2, etc )

move authentication/config related functions to auth-utils.[bash|sh]

create more authentication functions to reduce some clutter

add a lot of error checks, minute situations like chmod failing, failing to write to config file

bash script changes: export all sub functions in their sub scripts

export variables when it is created that are needed for parallel uploads

google-oauth2.[sh|bash]: Make changes for refactored functions | Misc changes

as it is supposed to be a sample script, so don't modify default config

new flag "add" - authenticates a new user but will use the client id and secret if available. If not, then same as create flag.

This is a huge change, literally and figuratively both.

I have tested multiple scenarios to make it break free, like with no config, with config having old values, config having old and new values both, config with just new values.

This has been working so far.

After this is merged then the service accounts pull request will be updated accordingly.

@Akianonymus is this PR safe to merge?

[Akianonymus]

@labbots Have to test again, it's been a while since i touched this.

Will be ready in this week probably, given no anamolies.

[Akianonymus]

@labbots This should be safe to merge now.

I have tried to test in many scenarios as possible, as mentioned in one of my previous comments in this thread, regarding config files and authentication.

For upload tests, i ran this script, which covers almost all of the uploading aspects of the script:-

#!/usr/bin/env bash

set -e

shell="${1:?Give Shell}"

cd "${shell}/release" || exit 1

LOGNAME="$((RANDOM * RANDOM))"
FILE="${LOGNAME}".testfile

trap 'exit' INT TERM
trap 'rm -rf "${FILE}"* "${LOGNAME}"* Test_gupload ; kill -- -$$' EXIT
trap '' TSTP # ignore ctrl + z

_show_log() {
    printf "%s\n" "$(< "${LOGNAME}")" && rm "${LOGNAME}"
    printf "\n"
}

# File test
printf "" >| "${FILE}"

DEFAULT_ARGS="./gupload ${FILE} -C Test_gupload --skip-internet-check"

${DEFAULT_ARGS}

${DEFAULT_ARGS} -d -r root -i "${LOGNAME}" -S
TEST_FILE_ID="$(: $(grep ID "${LOGNAME}") && printf "%s\n" "${_/ID: /}")"
_show_log

${DEFAULT_ARGS} -o -r root -i "${LOGNAME}" -S
_show_log

# Folder upload tests
mkdir -p Test_gupload/test

for i in {Test_gupload,Test_gupload/test}/{1..2}; do
    printf "%s\n" "" >| "${i}"
done

DEFAULT_FOLDER_ARGS="./gupload Test_gupload --skip-internet-check"

${DEFAULT_FOLDER_ARGS} -d -r root -i "${LOGNAME}" -S
_show_log

${DEFAULT_FOLDER_ARGS} -o -r root -i "${LOGNAME}"
_show_log

${DEFAULT_FOLDER_ARGS} -s -d -r root -i "${LOGNAME}"
_show_log

${DEFAULT_FOLDER_ARGS} -s -o -r root -i "${LOGNAME}" -S
_show_log

${DEFAULT_FOLDER_ARGS} -d -r root -i "${LOGNAME}" -p 2 -S
_show_log

${DEFAULT_FOLDER_ARGS} -o -r root -i "${LOGNAME}" -p 2
_show_log

${DEFAULT_FOLDER_ARGS} -s -d -r root -i "${LOGNAME}" -p 2
_show_log

${DEFAULT_FOLDER_ARGS} -s -o -r root -i "${LOGNAME}" -p 2 -S
_show_log

# file clone test
./gupload -C Test_gupload -cl "${TEST_FILE_ID}" -r root -i "${LOGNAME}" -S
_show_log

./gupload -C Test_gupload -cl "${TEST_FILE_ID}" -r root -i "${LOGNAME}" -d -S
_show_log

./gupload -C Test_gupload -cl "${TEST_FILE_ID}" -r root -i "${LOGNAME}" -o -S
_show_log
