Now that we run code concurrently in our loaders, we need to handle that in our tests.
We could enforce a deterministic ordering by mocking waitgroup or something like that,
but I think it's fine to let our tests handle some randomness given that prod itself
will have that randomness.
I've removed the patch test file because it was clunky, not providing much value, and
it would have been hard to refactor to the new pattern
This reverts commit 90613056ce, or the part that removed
a goroutine at least.
Reverting because this has caused an infinite wait for push/pull on windows.
We'll need to find out why that happens separately
This happens consistently for my when I close my MacBook's lid. It seems that
MacOS locks the user's keychain in this case, and since I have my keychain
provide the pass phrases for my ssh keys, fetching fails because it tries to
prompt me for a pass phrase.
This all worked correctly already, we have the FailOnCredentialRequest()
mechanism specifically for this situation, so all is great. The only problem was
that it was trying to pause the ongoing task while prompting the user for input;
but the task is nil for a background fetch (and should be).
I don't know why we're getting index.lock errors but they're impossile to stop
anyway given that other processes can be calling git commands. So we're retrying
a few times before re-raising. To do this we need to clone the command and the current
implementation for that is best-effort.
I do worry about the maintainability of that but we'll see how it goes.
Also, I thought you'd need to clone the task (if it exists) but now I think not;
as long as you don't call done twice on it you should be fine, and you shouldn't
be done'ing a task as part of running a command: that should happen higher up.
It's not clear what was happening but it seemed like we sometimes weren't
fully writing to our stdout buffer (which is used for the error message)
even though we had returned from cmd.Wait().
Not sure what the cause was but removing an unnecessary goroutine fixed it.
The global counter approach is easy to understand but it's brittle and depends on implicit behaviour that is not very discoverable.
With a global counter, if any goroutine accidentally decrements the counter twice, we'll think lazygit is idle when it's actually busy.
Likewise if a goroutine accidentally increments the counter twice we'll think lazygit is busy when it's actually idle.
With the new approach we have a map of tasks where each task can either be busy or not. We create a new task and add it to the map
when we spawn a worker goroutine (among other things) and we remove it once the task is done.
The task can also be paused and continued for situations where we switch back and forth between running a program and asking for user
input.
In order for this to work with `git push` (and other commands that require credentials) we need to obtain the task from gocui when
we create the worker goroutine, and then pass it along to the commands package to pause/continue the task as required. This is
MUCH more discoverable than the old approach which just decremented and incremented the global counter from within the commands package,
but it's at the cost of expanding some function signatures (arguably a good thing).
Likewise, whenever you want to call WithWaitingStatus or WithLoaderPanel the callback will now have access to the task for pausing/
continuing. We only need to actually make use of this functionality in a couple of places so it's a high price to pay, but I don't
know if I want to introduce a WithWaitingStatusTask and WithLoaderPanelTask function (open to suggestions).
I don't know if this is a hack or not: we run a git command and increment the pending action
count to 1 but at some point the command requests a username or password, so we need to prompt
the user to enter that. At that point we don't want to say that there is a pending action,
so we decrement the action count before prompting the user and then re-increment it again afterward.
Given that we panic when the counter goes below zero, it's important that it's not zero
when we run the git command (should be impossible anyway).
I toyed with a different approach using channels and a long-running goroutine that
handles all commands that request credentials but it feels over-engineered compared to this
commit's approach.
By constructing an arg vector manually, we no longer need to quote arguments
Mandate that args must be passed when building a command
Now you need to provide an args array when building a command.
There are a handful of places where we need to deal with a string,
such as with user-defined custom commands, and for those we now require
that at the callsite they use str.ToArgv to do that. I don't want
to provide a method out of the box for it because I want to discourage its
use.
For some reason we were invoking a command through a shell when amending a
commit, and I don't believe we needed to do that as there was nothing user-
supplied about the command. So I've switched to using a regular command out-
side the shell there
Instead, query the platform defaults only if the config is empty. This will be
necessary later to distinguish an empty config from a default config, so that we
can give deprecation warnings.
The "open" command is supposed to behave in the same way as double-clicking a
file in the Finder/Explorer. The concept of jumping to a specific line in the
file doesn't make sense for this; use "edit" instead.
These files were renamed from os_windows_test.go to os_test_windows.go (etc.) in
95b2e9540a. Since then, the tests have no longer run, since go only looks for
tests in files ending with "test.go".
It isn't important that the file name ends with "_windows.go", since there are
already build constrains in the files themselves.
The 8.2 release of OpenSSH added support for FIDO/U2F hardware
authenticators, which manifests in being able to create new types of SSH
key, named `ecdsa-sk` nad `ed25519-sk`. This is relevant to lazygit,
as those SSH keys can be used to authorise git operations over SSH, as
well as signing git commits. Actual code changes are required for
correct support, as the authentication process for these types of keys
is different than the process for types supported previously.
When an operation requiring credentials is initialised with a U2F
authenticator-backed key, the first prompt is:
Enter PIN for ${key_type} key ${path_to_key}:
at which point the user is supposed to enter a numeric (and secret) PIN,
specific to the particular FIDO/U2F authenticator using which the SSH
keypair was generated. Upon entering the correct key, the user is
supposed to physically interact with the authenticator to confirm
presence. Sometimes this is accompanied by the following text prompt:
Confirm user presence for key ${key_type} ${key_fingerprint}
This second prompt does not always occur and it is presumed that the
user will know to perform this step even if not prompted specifically.
At this stage some authenticator devices may also begin to blink a LED
to indicate that they're waiting for input.
To facilitate lazygit's interoperability with these types of keys, add
support for the first PIN prompt, which allows "fetch", "pull", and
"push" git operations to complete.
