This is just a cosmetic change that renames `Stripe.configuration` to
just `Stripe.config`. We use the shorter "config" in most other places
including `StripeClient#config`, so I feel that this is overall more
consistent.
This change is backwards compatible because the new accessor came in
with #968, and that hasn't been given a formal release yet.
I've left the class name as `StripeConfiguration` which IMO is fine. The
class uses the expanded form of the name while vars and accessors use
the shorter `config`. Also, `StripeConfiguration` has been around a
little bit longer, so renaming it is somewhat backwards incompatible
too.
This changes allows for each instance of StripeClient to have its own
configuration object instead of relying on the global config. Each
instance can be configured to override any global config values
previously set.
If #857 comes in, it turns out that we don't need Timecop anymore (it
doesn't freeze the monotic clock, so I had to find another way) -- here
we remove all mentions of it and drop the dependency.
I don't find it causes too much trouble so I'm not against bringing it
back in the future if we need it again, but it seems good for project
cleanliness to take it out for now.
Drops the use of `Time.now` in favor of using the system's monotonic
clock for various operations that calculate and use elapsed duration.
The latter is preferable because in some cases `Time.now` can be
unstable, like if it's set manually by a system administrator or an NTP
daemon.
I don't expect that the previous code would actually have caused trouble
in the vast majority of normal situations, so I'm not going to backport
anything, but this seems like good hygiene.
For better or worse I had to wrap the monotonic time calls in a new
`Util` function because (1) the normal invocation is long enough to have
caused a lot of overruns on our 80 character line lengths, and (2)
Timecop doesn't stub the monotonic clock, so the `Util` method gives us
a nice place that we can stub on where necessary.
* 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
Changes all arrays from classic Rack encoding:
``` sh
arr[]=...&arr[]=...&arr[]=...
```
To integer-indexed encoding:
``` sh
arr[0]=...&arr[1]=...&arr[2]=...
```
We think that this should be tractable now that we've fully converted
all endpoints over to the new AbstractAPIMethod infrastructure on the
backend (although we should do a little more testing to make sure that
all endpoints still work).
As part of the conversion, we also remove any places that we were "spot
encoding" to get required integer-indexed syntax. This should now all be
built in.
Remi pointed out in #666 that we basically just have to keep adding more
more onto the `Max` exception for both these rules every time we add a
new API resource.
Here I suggest that we modify the check on method length in two ways:
1. Permanently disable the cop on `Util.object_classes`. This is just
going to keep growing until we change are approach to it.
2. Choose a more reasonable maximum of 50 lines for elsewhere (IMO, the
default of 10 is just too short). Most of our methods already come in
below this, but there's a couple outliers like `#execute_request` in
`StripeClient`. If we knock over some of those, we could lower this
number again, but I suspect that we'd probably want somewhere closer
to 30 (instead of 10) event then.
I also disable the check on module length completely. I'm not convinced
this is a very good heuristic for code quality.
This changes the predicate supplied to the #colorize method to ensure
that if a logger is set, the colorizing ANSI escape codes are not applied.
This definitely appears to have been the intention behind the original
implementation, but the tests didn't reflect how .log_internal was
actually called. In reality, it is always supplied with an `out:`
argument, not nil. This caused all logger bound output to also be
colorized.
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.
