This change makes it so that when an env_role is updated to be None, the
role property on the env_role is changed to be None in addition to being
marked as deleted. This also adds in a check so that previously deleted
env_roles cannot be reassigned a role.
whitespace
The validator ListItemRequired() was only checking for None and an empty
string, not for strings that were multiple whitespace characters. This
fixes this issue by checking each item with regex to make sure it
contains non whitespace characters
The filter remove_empty_string() also was not checking for strings that
were multiple whitespace characters. This was also fixed by using regex
tomake sure that the string contains non whitespace characters, and also
clips any trailing whitespace.
In local development, the app will fail to start if it does not find the
directory specified by CRL_STORAGE_CONTAINER. This adds a few lines to
safely create that directory on startup and corresponding tests.
AT-AT needs to maintain a key-value CRL cache where each key is the DER
byte-string of the issuer and the value is a dictionary of the CRL file
path and expiration. This way when it checks a client certificate, it
can load the correct CRL by comparing the issuers. This is preferable to
loading all of the CRLs in-memory. However, it still requires that AT-AT
load and parse each CRL when the application boots. Because of the size
of the CRLs and their parsed, in-memory size, this leads to the
application spiking to use nearly 900MB of memory (resting usage is
around 50MB).
This change introduces a small function to ad-hoc parse the CRL and
obtain the information in the CRL we need: the issuer and the
expiration. It does this by reading the CRL byte-by-byte until it
reaches the ASN1 sequence that corresponds to the issuer, and then looks
ahead to find the nextUpdate field (i.e., the expiration date). The
CRLCache class uses this function to build its cache and JSON-serializes
the cache to disk. If another AT-AT application process finds the
serialized version, it will load that copy instead of rebuilding it. It
also entails a change to the function signature for the init method of
CRLCache: now it expects the CRL directory as its second argument,
instead of a list of locations.
The Python script invoked by `script/sync-crls` will rebuild the
location cache each time it's run. This means that when the Kubernetes
CronJob for CRLs runs, it will refresh the cache each time. When a new
application container boots, it will get the refreshed cache.
This also adds a nightly CircleCI job to sync the CRLs and test that the
ad-hoc parsing function returns the same result as a proper parsing
using the Python cryptography library. This provides extra insurance
that the function is returning correct results on real data.
The Celery worker cannot render URLs for the app without having a
SERVER_NAME value set. AT-AT's ability to send notifications when an
environment is ready is broken as a result.
This commit sets a null default value for SERVER_NAME in the default
config file. A setting must exist in the INI file in order to be
over-written by an environment variable, which is why we declare it as
null here. There is an additional kwarg, "allow_no_value", that must be
passed to ConfigParser to allow null values.
This also applies the correct domains as SERVER_NAME environment
variables in the Kubernetes ConfigMaps for the AWS and Azure Celery
workers.
Adds a CircleCI integration for Ghost Inspector
(https://ghostinspector.com), a headless browser testing SaaS. The
README is updated with details about how to run GI locally.
Removes the bootstrap setup for Selenium testing with BrowserStack.
Replace ApplicationInvitations._update_status() with revoke() because multiple functions used _update_status() and it was causing app roles to be disabled when they shouldn't have. Now app roles are disabled within the revoke function.
Updated Invitations.resend() to accept user details so the invite info
can be changed in the new invite
