As seen in #928, the `refresh` method doesn't work for an event class.
This is because event has a field called `request`, and it ends up
replacing the `request` method that it inherited from being an API
resource, so when `refresh` tries to make a request, it fails because it
tries to invoke it on the accessor added for the event's property.
Here we give `request` a much more unique name so that it will never
conflict with a property field again, and update all internal references
to use the new name. We use `alias` to make the old name available for
backwards compatibility reasons because its been around for so long that
people are probably calling it.
Fixes#928.
There are two kinds of API operations: collection and element specific.
The signature between the two is slightly different:
- **collection**: (params, opts)
- **element specific**: (id, params, opts)
If a user doesn't realize the difference, they may attempt to use the
collection signature when performing an element specific operation like:
```
Stripe::PaymentIntent.cancel('pi_1234', 'sk_test_key')
# Results in an error: NoMethodError: undefined method `key?' for "sk_test"
```
The resulting error message isn't very useful for debugging.
Instead,this PR adds a message letting the user know what it's expecting:
`request params should be either a Hash or nil (was a String)`
* Support backwards pagination with list's `#auto_paging_each`
Previously, `#auto_paging_each` would always try to paginate forward,
even if it was clear based on the list's current filters that the user
had been intending to iterate backwards by specifying an `ending_before`
filter exclusively.
Here we implement backwards iteration by detecting this condition,
reversing the current list data, and making new requests for the
previous page (instead of the next one) as needed, which allows the user
to handle elements in reverse logical order.
Reversing the current page's list is intended as a minor user feature,
but may possibly be contentious. For background, when backwards
iterating in the API, results are still returned in "normal" order. So
if I specifying `ending_before=7`, the next page would look like `[4, 5,
6`] instead of `[6, 5, 4]`. In `#auto_paging_each` I reverse it to `[6,
5, 4]` so it feels to the user like they're handling elements in the
order they're iterating, which I think is okay. The reason it might be
contentious though is that it could be a tad confusing to someone who
already understands the normal `ending_before` ordering in the API.
Fixes#864.
* Allow `ending_before` and `starting_after` to remain in hydrated list object
Previously, if you specified a non-nil non-string opt value, like a
symbol for `idempotency_key`, you'd get a pretty user-unfriendly error
from `Net::HTTP`:
```
/Users/brandur/.rbenv/versions/2.4.5/lib/ruby/2.4.0/net/http/header.rb:21:in `block in initialize_http_header': undefined method `strip' for :foo:Symbol (NoMethodError)
```
Here, we introduce a new argument error that makes it a little easier
for someone to read. The impetus for the change is that we had an
internal product quality report where someone ran into this and was
confused.
I'm pretty sure this change is backward compatible because `Net::HTTP`
would call `strip` on anything that was passed in as a value, and
generally just strings would support that. There may be some other less
common data type that was accidentally compatible that someone was
using, but that case should be quite unusual.
* Convert library to use built-in `Net::HTTP`
Moves the library off of Faraday and over onto the standard library's
built-in `Net::HTTP` module. The upside of the transition is that we
break away from a few dependencies that have caused us a fair bit of
trouble in the past, the downside is that we need more of our own code
to do things (although surprisingly, not that much more).
The biggest new pieces are:
* `ConnectionManager`: A per-thread class that manages a connection to
each Stripe infrastructure URL (like `api.stripe.com`,
`connect.stripe.com`, etc.) so that we can reuse them between
requests. It's also responsible for setting up and configuring new
`Net::HTTP` connections, which is a little more heavyweight
code-wise compared to other libraries. All of this could have lived in
`StripeClient`, but I extracted it because that class has gotten so
big.
* `MultipartEncoder`: A class that does multipart form encoding for file
uploads. Unfortunately, Ruby doesn't bundle anything like this. I
built this by referencing the Go implementation because the original
RFC is not very detailed or well-written. I also made sure that it was
behaving similarly to our other custom implementations like
stripe-node, and that it can really upload a file outside the test
suite.
There's some risk here in that it's easy to miss something across one of
these big transitions. I've tried to test out various error cases
through tests, but also by leaving scripts running as I terminate my
network connection and bring it back. That said, we'd certainly release
on a major version bump because some of the interface (like setting
`Stripe.default_client`) changes.
* Drop support for old versions of Ruby
Drops support for Ruby 2.1 (EOL March 31, 2017) and 2.2 (EOL March 31,
2018). They're removed from `.travis.yml` and the gemspec and RuboCop
configuration have also been updated to the new lower bound.
Most of the diff here are minor updates to styling as required by
RuboCop:
* String literals are frozen by default, so the `.freeze` we had
everywhere is now considered redundant.
* We can now use Ruby 1.9 style hash syntax with string keys like `{
"foo": "bar" }`.
* Converted a few heredocs over to use squiggly (leading whitespace
removed) syntax.
As discussed in Slack, I didn't drop support for Ruby 2.3 (EOL March 31,
2019) as we still have quite a few users on it. As far as I know
dropping it doesn't get us access to any major syntax improvements or
anything, so it's probably not a big deal.
* Make `CardError`'s `code` parameter named instead of positional (#816)
Makes the `code` parameter on `CardError` named instead of positional.
This makes it more consistent with the rest of the constructor's
parameters and makes instantiating `CardError` from `StripeClient`
cleaner.
This is a minor breaking change so we're aiming to release it for the
next major version of stripe-ruby.
* Bump Rubocop to latest version (#818)
* Ruby minimum version increase followup (#819)
* Remove old deprecated methods (#820)
* Remove all alias for list methods (#823)
* Remove UsageRecord.create method (#826)
* Remove IssuerFraudRecord (#827)
* Add ErrorObject to StripeError exceptions (#811)
* Tweak retry logic to be a little more like stripe-node (#828)
Tweaks the retry logic to be a little more like stripe-node's. In
particular, we also retry under these conditions:
* If we receive a 500 on a non-`POST` request.
* If we receive a 503.
I made it slightly different from stripe-node which checks for a 500
with `>= 500`. I don't really like that -- if we want to retry specific
status codes we should be explicit about it.
We're actively re-examining ways on how to make it easier for clients to
figure out when to retry right now, but I figure V5 is a good time to
tweak this because the modifications change the method signature of
`should_retry?` slightly, and it's technically a public method.
* Fix inverted sign for 500 retries (#830)
I messed up in #828 by (1) accidentally flipping the comparison against
`:post` when checking whether to retry on 500, and (2) forgetting to
write new tests for the condition, which is how (1) got through.
This patch fixes both those problems.
* Remove a few more very old deprecated methods (#831)
I noticed that we had a couple of other deprecated methods on `Stripe`
and `StripeObject` that have been around for a long time. May as well
get rid of them too -- luckily they were using `Gem::Deprecate` so
they've been producing annoying deprecated warnings for quite a while
now.
* Remove extraneous slash at the end of the line
* Reset connections when connection-changing configuration changes (#829)
Adds a few basic features around connection and connection manager
management:
* `clear` on connection manager, which calls `finish` on each active
connection and then disposes of it.
* A centralized cross-thread tracking system for connection managers in
`StripeClient` and `clear_all_connection_managers` which clears all
known connection managers across all threads in a thread-safe way.
The addition of these allow us to modify the implementation of some of
our configuration on `Stripe` so that it can reset all currently open
connections when its value changes.
This fixes a currently problem with the library whereby certain
configuration must be set before the first request or it remains fixed
on any open connections. For example, if `Stripe.proxy` is set after a
request is made from the library, it has no effect because the proxy
must have been set when the connection was originally being initialized.
The impetus for getting this out is that I noticed that we will need
this internally in a few places when we're upgrading to stripe-ruby V5.
Those spots used to be able to hack around the unavailability of this
feature by just accessing the Faraday connection directly and resetting
state on it, but in V5 `StripeClient#conn` is gone, and that's no longer
possible.
* Minor cleanup in `StripeClient` (#832)
I ended up having to relax the maximum method line length in a few
previous PRs, so I wanted to try one more cleanup pass in
`execute_request` to see if I could get it back at all.
The answer was "not by much" (without reducing clarity), but I found a
few places that could be tweaked. Unfortunately, ~50 lines is probably
the "right" length for this method in that you _could_ extract it
further, but you'd end up passing huge amounts of state all over the
place in method parameters, and it really wouldn't look that good.
* Do better bookkeeping when tracking state in `Thread.current` (#833)
This is largely just another cleanup patch, but does a couple main
things:
* Hoists the `last_response` value into thread state. This is a very
minor nicety, but effectively makes `StripeClient` fully thread-safe,
which seems like a minor nicety. Two calls to `#request` to the same
`StripeObject` can now be executed on two different threads and their
results won't interfere with each other.
* Moves state off one-off `Thread.current` keys and into a single one
for the whole client which stores a new simple type of record called
`ThreadContext`. Again, this doesn't change much, but adds some minor
type safety and lets us document each field we expect to have in a
thread's context.
* Add Invoice.list_upcoming_line_items method (#834)
* Bump Rubocop to 0.57.2
* Style/StderrPuts: Use warn instead of .puts
* Style/ExpandPathArguments: Use expand_path('../test_helper', __dir__) instead of expand_path('../../test_helper', __FILE__)
* Style/Encoding: Unnecessary utf-8 encoding comment
* Style/StringLiterals: Prefer double-quoted strings
* Style/AccessModifierDeclarations
* Style/FormatStringToken: Prefer annotated tokens
* Naming/UncommunicativeMethodParamName
* Metrics/LineLength: set maximum line length to 100 characters
* Style/IfUnlessModifier: Favor modifier if usage when having a single-line body
* Style/ClassVars
* Metrics/LineLength: set maximum line length to 80 characters (default)
* Style/AccessModifierDeclarations: EnforcedStyle: inline
Adds the magic `frozen_string_literal: true` comment to every file and
enables a Rubocop rule to make sure that it's always going to be there
going forward as well.
See here for more background [1], but the basic idea is that unlike many
other languages, static strings in code are mutable by default. This has
since been acknowledged as not a particularly good idea, and the
intention is to rectify the mistake when Ruby 3 comes out, where all
string literals will be frozen. The `frozen_string_literal` magic
comment was introduced in Ruby 2.3 as a way of easing the transition,
and allows libraries and projects to freeze their literals in advance.
I don't think this is breaking in any way: it's possible that users
might've been pulling out one of are literals somehow and mutating it,
but that would probably not have been useful for anything and would
certainly not be recommended, so I'm quite comfortable pushing this
change through as a minor version.
As discussed in #641.

Makes the `operations` argument to `nested_resource_class_methods`
required and adds explicit lists to any invocations that were missing
one.
The impetus here is that I think it's more easily digestible if each
call site is explicit about what operations it supports and therefore
which methods it's about to create on the class.
Excludes `idempotency_key` from opts to persist between API requests.
Obviously the same idempotency key is not something that we ever want to
use again.
Fixes#598.
We were previously using a bit of a hack to get a free deep copy
implementation through Ruby's marshaling framework. Lint call this out
as a security problem though, and rightfully so: when combined with
unsanitized user input, unmarshaling can result in very serious security
breaches involving arbitrary code execution.
This patch removes all uses of marshal/unmarshal in favor of
implementing a deep copy method for `StripeObject`. I also reworked some
of the constants around what keys are available for `opts`. I'm still
not completely happy with the results, but I think it's going to need a
slightly larger refactor in order to get somewhere truly good.
There is what could be a breaking change for people doing non-standard
stuff with the library: the opts that we copy with an object are now
whitelisted, so if they were being used to pass around extraneous data,
that might not work as expected anymore. But because this is a contract
that we never committed to, I don't think I'd bump the major version for
change.
I wanted to see what fixing Rubocop TODOs was like, so I tried to
eliminate all the easy ones. Most of these were pretty easy, and the
changes required are relatively minimal.
Some of the stuff left is harder. Pretty much everything under
`Metrics/*` is going to be a pretty big yak shave. A few of the others
are just going to need a little more work (e.g. `Style/ClassVars` and
`Style/GuardClause`). Going to stop here for now.
As described in #481, adding a protected field like `legal_entity` as
part of an update API operation can cause some issues like a custom
encoding scheme not being considered and special handling around empty
values being ignored.
As a an easy fix for this, let's disallow access to protected fields in
the same way that we disallow them from being set directly on an
instance of a given model.
Helps address (but is not a complete fix for) #481.
* Rename the `Update` operation to `Save`
* Add the `update` class method to all saveable resources
* Add tests for update method
* Add tests for plans, invoice items, and application fees
