This will mainly be beneficial when a very large inventory is being
used, however it may also help with some very large playbooks.
* Add a surrogate_then_replace error strategy to keep to_bytes from tracebacking by default
* Port all code that explicitly used surrogate_or_replace to surrogate_then_replace
* Fix bug (#18355) where encrypted inventories fail
This is first part of fix for #18355
* Make DataLoader._get_file_contents return bytes
The issue #18355 is caused by a change to inventory to
stop using _get_file_contents so that it can handle text
encoding itself to better protect against harmless text
encoding errors in ini files (invalid unicode text in
comment fields).
So this makes _get_file_contents return bytes so it and other
callers can handle the to_text().
The data returned by _get_file_contents() is now a bytes object
instead of a text object. The callers of _get_file_contents() have
been updated to call to_text() themselves on the results.
Previously, the ini parser attempted to work around
ini files that potentially include non-vailid unicode
in comment lines. To do this, it stopped using
DataLoader._get_file_contents() which does the decryption of
files if vault encrypted. It didn't use that because _get_file_contents
previously did to_text() on the read data itself.
_get_file_contents() returns a bytestring now, so ini.py
can call it and still special case ini file comments when
converting to_text(). That also means encrypted inventory files
are decrypted first.
Fixes#18355
Prior to this commit, the ini parser would fail if the inventory was
not 100% utf-8. This commit makes this slightly more robust by
omitting full line comments from that requirement.
Fixes#17593
* refactor ignore_limits_and_restrictions
into ignore_limits and ignore_limitations
* add ansible_play_hosts_all
* update docs re ansible_play_hosts_all
* only use play.hosts when is has a value
* replace ansible_play_hosts with ansible_play_hosts_all
* remove unnecessary var
When an inventory file looks executable (with a #!) but
isn't, the error message could be confusing. Especially
if the inventory file was named something like 'inventory'
or 'hosts'. Add some context and quote the filename.
This is based on https://github.com/ansible/ansible/pull/15758
* Add a new config option to cache the check for controlpersist on the
control machine.
Fixes#15844
* Remove the option and make the behavior the default
* Make the check for controlpersist cache its status per-ssh executable
We couldn't copy to_unicode, to_bytes, to_str into module_utils because
of licensing. So once created it we had two sets of functions that did
the same things but had different implementations. To remedy that, this
change removes the ansible.utils.unicode versions of those functions.
for `VariableManager._get_magic_variables()`.
This saves a lot of time re-iterating the nearly always constant global
list of groups and their members.
Generate once and cache, and invalidate cache in case `add_host:` or
`group_by:` are used.
The flag new_pb_basedir is not being utilized in Inventory._get_hostgroup_vars,
leading to the situation where an inventory with no playbook basedir set will
read host/group vars from the $CWD, regardless of the inventory and/or playbook
relative location. This patch corrects that by not using the playbook basedir
if it is unset (None).
This patch also corrects a bug in which the VariableManager would accumulate
host/group vars files, which could lead to incorrect vars files being used when
playbooks are run from different directories containing their own group/host vars
directories.
Fixes#16953
* Revert "There can be only one localhost"
This reverts commit 5f1bbb4fcd.
this broke several usages of localhost, see #16882, #16898 and #16886
* ensure there is only 1 localhost
fixes#16886, #16882 and #16898
- make sure localhost exists before returning it
- optimzed host caching
- ensure we always return a host object
We want to update host vars for all hosts (even those that might
have failed), and the in case of a refresh_inventory, the code has
a stale restrictions list at this point anyway.
The changes to exclude implicit localhosts from group patterns exposed
the bug that we sometimes create multiple implicit localhosts, which
caused some bugs with things like includes, where the host was used as
an entry into a dict, so having multiple meant that the incorrect host
(with a different uuid) was found and includes were not executed for
implicit localhosts.
* In the VariableManager, we were not properly tracking if a file
had already been loaded, so we continuously append data to the end
of the list there for host and group vars, meaning large sets of data
are duplicated multiple times
* In the inventory, we were merging the host/group vars with the vars
local to the host needlessly, as the VariableManager already handles that.
This leads to needless duplication of the data and makes combining the
vars in VariableManager take even longer.
Ansible excessively checks the file system for the potential presence of
`group_vars` and `host_vars` files.
For large numbers of groups this leads to combinatorial performance
issues.
This commit generates a set of group_vars and host_vars filenames using
`os.listdir()` in every possible location and then checks against the sets
before making a stat of the file system.
Also included in this commit is caching of the base directory lookup
for the inventory.
Issue #15633 observes that a meta: inventory_refresh task causes the playbook
to exit. An inventory refresh flushes all caches and rebuilds all host
objects, assigning new UUIDs to each. These new host UUIDs currently fail to
match those on host objects stored for restrictions in the inventory, causing
the playbook to exit for having no hosts to run further tasks against.
This changeset attempts to address this issue by storing host restrictions
by name, and comparing inventory host names against these names when applying
restrictions in get_hosts.
* now you can specify a yaml invenotry file
* ansible_group_priority will now set this property on groups
* added example yaml inventory
* TODO: make group var merging depend on priority
groups, child/parent relationships should remain unchanged.
The use of realpath means when following symlinks the actual path is
used when loading these files in the VariableManager, which may not
line up with the host or group name specified.
Fixes#14545
by moving to en-bloc unicode conversion to act on scripts stdout
Both python-json and simplejson always return unicode strings when using
their loads() method on unicode strings. This is true at least since
2009. This makes checking each substring unnecessary, because we do not
need to recursively check the strings contained in the inventory dict
later one-by-one
This commit makes parsing of large dynamic inventory at least 2 seconds
faster.
cf: https://github.com/towolf/ansible-large-inventory-testcase
This prevents a bug where the existing cache outside of the class
is not cleared when creating a new Inventory object. This only really
affects people using the API directly right now, but wanted to fix it
to prevent weird errors from popping up.
