* Update yaml-style in password-lookup example
##### SUMMARY
Update the yaml-style in a password-lookup example to match best-practices.
##### ISSUE TYPE
- Docs Pull Request
##### COMPONENT NAME
password_lookup plugin
##### ANSIBLE VERSION
devel
* remove whitespace
* Share the implementation of hashing for both vars_prompt and password_hash.
* vars_prompt with encrypt does not require passlib for the algorithms
supported by crypt.
* Additional checks ensure that there is always a result.
This works around issues in the crypt.crypt python function that returns
None for algorithms it does not know.
Some modules (like user module) interprets None as no password at all,
which is misleading.
* The password_hash filter supports all parameters of passlib.
This allows users to provide a rounds parameter, fixing #15326.
* password_hash is not restricted to the subset provided by crypt.crypt,
fixing one half of #17266.
* Updated documentation fixes other half of #17266.
* password_hash does not hard-code the salt-length, which fixes bcrypt
in connection with passlib.
bcrypt requires a salt with length 22, which fixes#25347
* Salts are only generated by ansible when using crypt.crypt.
Otherwise passlib generates them.
* Avoids deprecated functionality of passlib with newer library versions.
* When no rounds are specified for sha256/sha256_crypt and sha512/sha512_crypt
always uses the default values used by crypt, i.e. 5000 rounds.
Before when installed passlibs' defaults were used.
passlib changes its defaults with newer library versions, leading to non
idempotent behavior.
NOTE: This will lead to the recalculation of existing hashes generated
with passlib and without a rounds parameter.
Yet henceforth the hashes will remain the same.
No matter the installed passlib version.
Making these hashes idempotent.
Fixes#15326Fixes#17266Fixes#25347 except bcrypt still uses 2a, instead of the suggested 2b.
* random_salt is solely handled by encrypt.py.
There is no _random_salt function there anymore.
Also the test moved to test_encrypt.py.
* Uses pytest.skip when passlib is not available, instead of a silent return.
* More checks are executed when passlib is not available.
* Moves tests that require passlib into their own test-function.
* Uses the six library to reraise the exception.
* Fixes integration test.
When no rounds are provided the defaults of crypt are used.
In that case the rounds are not part of the resulting MCF output.
NOTE:
1. use os.open() with os.O_CREAT|os.O_EXCL to check existence
and create a lock file if not exists, it's an atomic operation
2. the fastest process will create the lock file and others will
wait until the lock file is removed
3. after the writer finished writing to the password file, all the reading
operations use built-in open so processes can read the file parallel
According to the do_encrypt interface, encrypt arg should be the hash method name used for encrypting returning password. But in the doc and lookup code it's a boolean flag, correct it to string.
* Remove uses of assert in production code
* Fix assertion
* Add code smell test for assertions, currently limited to lib/ansible
* Fix assertion
* Add docs for no-assert
* Remove new assert from enos
* Fix assert in module_utils.connection
* finalize lookup documentation
* minor fixes to ansible-doc
- actually show which file caused error on when listing plugins
- removed redundant display of type and name
* smart quote fixes from toshio
* [password] _random_password -> random_password and moved to util/encrypt.py
* [passwordstore] Use built-in random_password instead of pwgen utility
* [passwordstore] Add integration tests
* Update module_utils.six to latest
We've been held back on the version of six we could use on the module
side to 1.4.x because of python-2.4 compatibility. Now that our minimum
is Python-2.6, we can update to the latest version of six in
module_utils and get rid of the second copy in lib/ansible/compat.
I have from time to time a need of random password without
wanting to write them down (one example is mailman list creation,
that requires a password to be given to be sent to the list owner).
But using /dev/null do not return null, but the empty string, which
doesn't generate a password at all and so do not achieve my use case.
* Improve unit testing of 'password' lookup
The tests showed some UnicodeErrors for the
cases where the 'chars' param include unicode,
causing the 'getattr(string, c, c)' to fail.
So the candidate char generation code try/excepts
UnicodeErrors there now.
Some refactoring of the password.py module to make
it easier to test, and some new tests that cover more
of the password and salt generation.
* More refactoring and fixes.
* manual merge of text enc fixes from pr17475
* moving methods to module scope
* more refactoring
* A few more text encoding fixes/merges
* remove now unused code
* Add test cases and data for _gen_candidate_chars
* more test coverage for password lookup
* wip
* More text encoding fixes and test coverage
* cleanups
* reenable text_type assert
* Remove unneeded conditional in _random_password
* Add docstring for _gen_candidate_chars
* remove redundant to_text and list comphenesion
* Move set of 'chars' default in _random_password
on py2, C.DEFAULT_PASSWORD_CHARS is a regular str
type, so the assert here fails. Move setting the
default into the method and to_text(DEFAULT_PASSWORD_CHARS)
if it's needed.
* combine _random_password and _gen_password
* s/_create_password_file/_create_password_file_dir
* native strings for exception msgs
* move password to_text to _read_password_file
* move to_bytes(content) to _write_password_file
* add more test assertions about genned pw's
* Some cleanups to alikins and abadger's password lookup refactoring:
* Make DEFAULT_PASSWORD_CHARS into a text string in constants.py
- Move this into the nonconfigurable section of constants.
* Make utils.encrypt.do_encrypt() return a text string because all the
hashes in passlib should be returning ascii-only strings and they are
text strings in python3.
* Make the split up of functions more sane:
- Don't split such that conditionals have to occur in two separate functions.
- Don't go overboard: Good to split file system manipulation from parsing
but we don't need to do every file manipulation in a separate
function.
- Don't split so that creation of the password store happens in two
parts.
- Don't split in such a way that no decisions are made in run.
* Organize functions by when it gets called from run().
* Run all potential characters through the gen_candidate_chars function
because it does both normalization and validation.
* docstrings for functions
* Change when we store salt slightly. Store it whenever it was already
present in the file as well as when encrypt is requested. This will
head of potential idempotence bugs where a user has two playbook tasks
using the same password and in one they need it encrypted but in the
other they need it plaintext.
* Reorganize tests to follow the order of the functions so it's easier
to figure out if/where a function has been tested.
* Add tests for the functions that read and write the password file.
* Add tests of run() when the password has already been created.
* Test coverage currently at 100%
* Lookup unencrypted password must not include salt
* Integration test lookup: remove previous directory
* Test that lookup password doesn't return salt
* Lookup password: test behavior with empty encrypt parameter
Closes#16189
Removed deletion of salt param from lookup file by 'password' lookup_filter.
Old behaviour leads to constant changed status when two tasks uses same lookup,
one with 'encrypt' parameter, and other without.
For example:
tasks:
- name: Create user
user:
password: "{{ lookup('password', inventory_dir + '/creds/user/pass' ncrypt=sha512_crypt) }}"
...
# Lookup file 'creds/user/pass' now contain password with salt
- name: Create htpasswd
htpasswd:
password: "{{ lookup('password', inventory_dir + '/creds/user/pass') }}"
...
# Salt gets deleted from lookup file 'creds/user/pass'
# Next run of "Create user" task will create it again and will have 'changed' status
