Summary: I know this is ultimately pointless but feel better about pushing back on users when there is no possible way they could be acting in good faith.

Test Plan: Read documents.

It is nearly impossible for us to resolve many issues if we can not reproduce

Unreproducible Problems
=======================
Before we can fix a bug, we need to reproduce it. If we can't reproduce a
problem, we can't tell if we've fixed it and often won't be able to figure out
why it is occurring.
Most problems reproduce easily, but some are more difficult to reproduce. We
will generally make a reasonable effort to reproduce problems, but sometimes
we will be unable to reproduce an issue.
Many of these unreproducible issues turn out to be bizarre environmental
problems that are unique to one user's install, and figuring out what is wrong
takes a very long time with a lot of back and forth as we ask questions to
narrow down the cause of the problem. When we eventually figure it out and fix
it, few others benefit (in some cases, no one else). This sort of fishing
expedition is not a good use of anyone's time, and it's very hard for us to
prioritize solving these problems because they represent a huge effort for very
little benefit.
We will make a reasonable effort to reproduce problems, but can not help with
issues which we can't reproduce. You can make sure we're able to help resolve
your issue by generating clear reproduction steps.

@title Providing Reproduction Steps
@group detail
Describes how to provide reproduction steps.
Overview
========
When you submit a bug report about Phabricator, you **MUST** include
reproduction steps. We can not help you with bugs we can not reproduce, and
will not accept reports which omit reproduction steps or have incomplete or
insufficient instructions.
This document explains what we're looking for in good reproduction steps.
Briefly:
- Reproduction steps must allow us to reproduce the problem locally on a
clean, up-to-date install of Phabricator.
- Reproduction should be as simple as possible.
Good reproduction steps can take time to write out clearly, simplify, and
verify. As a reporter, we expect you to shoulder as much of this burden as you
can, to make make it easy for us to reproduce and resolve bugs.
We do not have the resources to pursue reports with limited, inaccurate, or
incomplete reproduction steps, and will not accept them. These reports require
large amounts of our time and are often fruitless.
Example Reproduction Steps
==========================
Here's an example of what good reproduction steps might look like:
---
Reproduction steps:
- Click "Create Event" in Calendar.
- Fill in the required fields with any text (name, description, etc).
- Set an invalid time for one of the dates, like the meaningless string
"Tea Time". This is not valid, so we're expecting an error when we
submit the form.
- Click "Create" to save the event.
Expected result:
- Form reloads with an error message about the specific mistake.
- All field values are retained.
Actual result:
- Form reloads with an error message about the specific mistake.
- Most values are discarded, so I have to re-type the name, description, etc.
---
These steps are **complete** and **self-contained**: anyone can reproduce the
issue by following these steps. These steps are **clear** and **easy to
follow**. These steps are also simple and minimal: they don't include any
extra unnecessary steps.
Finally, these steps explain what the reporter expected to happen, what they
observed, and how those behaviors differ. This isn't as important when the
observation is an obvious error like an exception, but can be important if a
behavior is merely odd or ambiguous.
Reliable Reproduction
=====================
When you file a bug report, the first thing we do to fix it is to try to
reproduce the problem locally on an up-to-date install of Phabricator. We will
do this by following the steps you provide. If we can recreate the issue
locally, we can almost always resolve the problem (often very promptly).
However, many reports do not have enough information, are missing important
steps, or rely on data (like commits, users, other projects, permission
settings, feed stories, etc) that we don't have access to. We either can't
follow these steps, or can't reproduce issues by following them.
Reproduction steps must be complete and self-contained, and must allow
**anyone** to reproduce the issue on a new, empty install of Phabricator. If
the bug you're seeing depends on data or configuration which would not be
present on a new install, you need to include that information in your steps.
For example, if you're seeing an issue which depends on a particular policy
setting or configuration setting, you need to include instructions for creating
the policy or adjusting the setting in your steps.
Getting Started
===============
To generate reproduction steps, first find a sequence of actions which
reproduce the issue you're seeing reliably.
Next, write down everything you did as clearly as possible. Make sure each step
is self-contained: anyone should be able to follow your steps, without access
to private or proprietary data.
Now, to verify that your steps provide a complete, self-contained way to
reproduce the issue, follow them yourself on a new, empty, up-to-date instance
of Phabricator.
If you can't easily start an empty instance locally, you can launch an empty
instance on Phacility in about 60 seconds (see the "Resources" section for
details).
If you can follow your steps and reproduce the issue on a clean instance,
we'll probably be able to follow them and reproduce the issue ourselves.
If you can't follow your steps because they depend on information which is not
available on a clean instance (for example, a certain config setting), rewrite
them to include instrutions to create that information (for example, adjusting
the config to the problematic value).
If you follow your instructions but the issue does not reproduce, the issue
might already be fixed. Make sure your install is up to date.
If your install is up to date and the issue still doesn't reproduce on a clean
install, your reproduction steps are missing important information. You need to
figure out what key element differs between your install and the clean install.
Once you have working reproduction steps, your steps may have details which
aren't actually necessary to reproduce the issue. You may be able to simplify
them by removing some steps or describing steps more narrowly. For help, see
"Simplifying Steps" below.
Resources
=========
We provide some resources which can make it easier to start building steps, or
to simplify steps.
**Phacility Test Instances**: You can launch a new, up-to-date instance of
Phabricator on Phacility in about a minute at <https://admin.phacility.com>.
These instances run `stable`.
You can use these instances to make sure that issues haven't already been
fixed, that they reproduce on a clean install, or that your steps are really
complete, and that the root cause isn't custom code or local extensions. Using
a test instance will avoid disrupting other users on your install.
**Test Repositories**: There are several test repositories on
`secure.phabriactor.com` which you can push commits to if you need to build
an example to demonstrate a problem.
For example, if you're seeing an issue with a certain filename but the commit
where the problem occurs is in a proprietary internal repository, push a commit
that affects a file with a similar name to a test repository, then reproduce
against the test data. This will allow you to generate steps which anyone can
follow.
Simplifying Steps
=================
If you aren't sure how to simplify reproduction steps, this section has some
advice.
In general, you'll simplify reproduction steps by first finding a scenario
where the issue reproduces reliably (a "bad" case) and a second, similar
situation where it does not reproduce (a "good" case). Once you have a "bad"
case and a "good" case, you'll change the scenarios step-by-step to be more
similar to each other, until you have two scenarios which differ only a very
small amount. This remaining difference usually points clearly at the root
cause of the issue.
For example, suppose you notice that you get an error if you commit a file
named `A Banana.doc`, but not if you commit a file named `readme.md`. In
this case, `A Banana.doc` is your "bad" case and `readme.md` is your "good"
case.
There are several differences between these file names, and any of them might
be causing the problem. To narrow this down, you can try making the scenarios
more similar. For example, do these files work?
- `A_Banana.doc` - Problem with spaces?
- `A Banana.md` - File extension issue?
- `A Ban.doc` - Path length issue?
- `a banana.doc` - Issue with letter case?
Some of these probably work, while others might not. These could lead you to a
smaller case which reproduces the problem, which might be something like this:
- Files like `a b`, which contain spaces, do not work.
- Files like `a.doc`, which have the `.doc` extension, do not work.
- Files like `AAAAAAAAAA`, which have more than 9 letters, do not work.
- Files like `A`, which have uppercase letters, do not work.
With a simpler reproduction scenario, you can simplify your steps to be more
tailored and mimimal. This will help us pointpoint the issue more quickly and
be more certain that we've understood and resolved it.
It is more important that steps be complete than that they be simple, and it's
acceptable to submit complex instructions if you have difficulty simplifying
them, so long as they are complete, self-contained, and accurately reproduce
the issue.
Things to Avoid
===============
These are common mistakes when providing reproduction instructions:
**Insufficient Information**: The most common issue we see is instructions
which do not have enough information: they are missing critical details which
are necessary in order to follow them on a clean install.
**Inaccurate Steps**: The second most common issue we see is instructions
which do not actually reproduce a problem when followed on a clean, up-to-date
install. Verify your steps by testing them.
**Private Information**: Some users provide reports which hinge on the
particulars of private commits in proprietary repositories we can not access.
This is not useful, because we can not examine the underlying commit to figure
out why it is causing an issue.
Instead, reproduce the issue in a public repository. There are several test
repositories available which you can push commits to in order to construct a
reproduction case.
**Screenshots**: Screenshots can be helpful to explain a set of steps or show
what you're seeing, but they usually aren't sufficient on their own because
they don't contain all the information we need to reproduce them.
For example, a screenshot may show a particular policy or object, but not have
enough information for us rebuild a similar object locally.
Alternatives
============
If you have an issue which you can't build reproduction steps for, or which
only reproduces in your environment, or which you don't want to narrow down
to a minimal reproduction case, we can't accept it as a bug report. These
issues are tremendously time consuming for us to pursue and rarely benefit
more than one install.
If the issue is important but falls outside the scope of permissible bug
reports, we're happy to provide more tailored support at consulting rates. See
[[ https://secure.phabricator.com/w/consulting/ | Consulting ]] for details.

@title Providing Version Information
@group detail
How to provide version information with reports made to the upstream.
Overview
========
When you submit a bug report, we require that you include version information.
Despite our insistence that users update before reporting issues, many reports
we receive describe issues which have already been resolved. Including version
information in your report allows us to quickly determine that you are out of
date and that updating will fix your issue.
That said, your report must also include reproduction steps, and you should be
unable to generate valid reproduction steps for an issue which has already been
resolved because valid reproduction steps must also reproduce against a clean,
up-to-date install. See @{article:Providing Reproduction Steps} for details.
Phabricator Version
===================
To get Phabricator version information:
- Go to the {nav Config} application. You can type "Config" into the global
search box, or navigate to `https://your.install.com/config/`. You must
be an administrator to access this application.
- Click {nav Versions} in the left menu.
- Copy and paste all of the information on the page into your report.
Arcanist Version
================
To get Arcanist version information:
- Run `arc version`.
- Copy and paste all of the output into your report.
Other Versions
==============
In general, we use `git` commit hashes as version identifiers, so you can
identify the version of something by running `git show` and copy/pasting the
hash from the output. This may be useful if you're encountering an issue which
prevents you from reaching the version reporting screen.
