[cli] Reimplement the interactive renderer
The display pipleline looks like this:
╭──────╮
│Engine│
╰──────╯
⬇ engine events
╭────────────────╮
│Progress Display│
╰────────────────╯
⬇ display events: ticks, resource updates, system messages
╭─────────────────╮
│Progress Renderer│
╰─────────────────╯
⬇ text
╭────────╮
│Terminal│
╰────────╯
The existing implementation of the interactive Progress Renderer is broken
into two parts, the display renderer and the message renderer. The display
renderer converts display events into progress messages, each of which
generally represents a single line of text at a particular position in
the output. The message renderer converts progress messages into screen
updates by identifying whether or not the contents of a particular
message have changed and if so, re-rendering its output line. In
somewhat greater detail:
╭────────────────╮
│Display Renderer│
╰────────────────╯
⬇ convert resource rows into a tree table
⬇ convert the tree table and system messages into lines
⬇ convert each line into a progress message with an index
╭────────────────╮
│Message Renderer│
╰────────────────╯
⬇ if the line identified in a progress message has changed,
⬇ go to that line on the terminal, clear it, and update it
╭────────╮
│Terminal│
╰────────╯
This separation of concerns is unnecessary and makes it difficult to
understand where and when the terminal is updated. This approach also
makes it somewhat challenging to change the way in which the display
interacts with the terminal, as both the display renderer and the
message renderer need to e.g. understand terminal dimensions, movement,
etc.
These changes reimplement the interactive Progress Renderer using a
frame-oriented approach. The display is updated at 60 frame per second.
If nothing has happened to invalidate the display's contents (i.e. no
changes to the terminal geometry or the displayable contents have occurred),
then the frame is not redrawn. Otherwise, the contents of the display
are re-rendered and redrawn.
An advantage of this approach is that it made it relatively simple to
fix a long-standing issue with the interactive display: when the number
of rows in the output exceed the height of the terminal, the new
renderer clamps the output and allows the user to scroll the tree table
using the up and down arrow keys.

Decouple persist and display events (#15709)
<!---
Thanks so much for your contribution! If this is your first time
contributing, please ensure that you have read the
[CONTRIBUTING](https://github.com/pulumi/pulumi/blob/master/CONTRIBUTING.md)
documentation.
-->
# Description
Retry #15529 with fix for the issue that required the revert in #15705
This removes a scenario where events could not be persisted to the cloud
because they were waiting on the same event being displayed
Instead of rendering the tree every time a row is updated, instead, this
renders when the display actually happens in the the `frame` call. The
renderer instead simply marks itself as dirty in the `rowUpdated`,
`tick`, `systemMessage` and `done` methods and relies on the frame being
redrawn on a 60Hz timer (the `done` method calls `frame` explicitly).
This makes the rowUpdated call exceedingly cheap (it simply marks the
treeRenderer as dirty) which allows the ProgressDisplay instance to
service the display events faster, which prevents it from blocking the
persist events.
This requires a minor refactor to ensure that the display object is
available in the frame method
Because the treeRenderer is calling back into the ProgressDisplay object
in a goroutine, the ProgressDisplay object needs to be thread safe, so a
read-write mutex is added to protect the `eventUrnToResourceRow` map.
The unused `urnToID` map was removed in passing.
## Impact
There are scenarios where the total time taken for an operation was
dominated by servicing the events.
This reduces the time for a complex (~2000 resources) `pulumi preview`
from 1m45s to 45s
For a `pulumi up` with `-v=11` on a the same stack, where all the
register resource spans were completing in 1h6m and the
postEngineEventBatch events were taking 3h45m, this PR removes the time
impact of reporting the events (greatly inflated by the high verbosity
setting) and the operation takes the anticipated 1h6m
<!--- Please include a summary of the change and which issue is fixed.
Please also include relevant motivation and context. -->
Fixes #15668
This was happening because the renderer was being marked dirty once per
second in a tick event, which caused frame to redraw. There is a check
in the render method that `display.headerRow` is not nil that was
previously used to prevent rendering when no events had been added. This
check is now part of the `markDirty` logic
Some of the tests needed to be updated to make this work and have also
been refactored
## Checklist
- [X] I have run `make tidy` to update any new dependencies
- [X] I have run `make lint` to verify my code passes the lint check
- [ ] I have formatted my code using `gofumpt`
<!--- Please provide details if the checkbox below is to be left
unchecked. -->
- [X] I have added tests that prove my fix is effective or that my
feature works
<!---
User-facing changes require a CHANGELOG entry.
-->
- [ ] I have run `make changelog` and committed the
`changelog/pending/<file>` documenting my change
<!--
If the change(s) in this PR is a modification of an existing call to the
Pulumi Cloud,
then the service should honor older versions of the CLI where this
change would not exist.
You must then bump the API version in
/pkg/backend/httpstate/client/api.go, as well as add
it to the service.
-->
- [ ] Yes, there are changes in this PR that warrants bumping the Pulumi
Cloud API version
<!-- @Pulumi employees: If yes, you must submit corresponding changes in
the service repo. -->

Add display to the engine tests (#16050)
We want to add more test coverage to the display code. The best way to
do that is to add it to the engine tests, that already cover most of the
pulumi functionality.
It's probably not really possible to review all of the output, but at
least it gives us a baseline, which we can work with.
There's a couple of tests that are flaky for reasons I don't quite
understand yet. I marked them as to skip and we can look at them later.
I'd rather get in the baseline tests sooner, rather than spending a
bunch of time looking at that. The output differences also seem very
minor, so not super concerning.
The biggest remaining issue is that this doesn't interact well with the
Chdir we're doing in the engine. We could either pass the CWD through,
or just try to get rid of that Chdir. So this should only be merged
after https://github.com/pulumi/pulumi/pull/15607.
I've tried to split this into a few commits, separating out adding the
testdata, so it's hopefully a little easier to review, even though the
PR is still quite large.
One other thing to note is that we're comparing that the output has all
the same lines, and not that it is exactly the same. Because of how the
engine is implemented, there's a bunch of race conditions otherwise,
that would make us have to skip a bunch of tests, just because e.g.
resource A is sometimes deleted before resource B and sometimes it's the
other way around.
The biggest downside of that is that running with `PULUMI_ACCEPT` will
produce a diff even when there are no changes. Hopefully we won't have
to run that way too often though, so it might not be a huge issue?

An advantage of this approach is that it made it relatively simple to
fix a long-standing issue with the interactive display: when the number
of rows in the output exceed the height of the terminal, the new
renderer clamps the output and allows the user to scroll the tree table
using the up and down arrow keys.

[cli] Reimplement the interactive renderer
The display pipleline looks like this:
╭──────╮
│Engine│
╰──────╯
⬇ engine events
╭────────────────╮
│Progress Display│
╰────────────────╯
⬇ display events: ticks, resource updates, system messages
╭─────────────────╮
│Progress Renderer│
╰─────────────────╯
⬇ text
╭────────╮
│Terminal│
╰────────╯
The existing implementation of the interactive Progress Renderer is broken
into two parts, the display renderer and the message renderer. The display
renderer converts display events into progress messages, each of which
generally represents a single line of text at a particular position in
the output. The message renderer converts progress messages into screen
updates by identifying whether or not the contents of a particular
message have changed and if so, re-rendering its output line. In
somewhat greater detail:
╭────────────────╮
│Display Renderer│
╰────────────────╯
⬇ convert resource rows into a tree table
⬇ convert the tree table and system messages into lines
⬇ convert each line into a progress message with an index
╭────────────────╮
│Message Renderer│
╰────────────────╯
⬇ if the line identified in a progress message has changed,
⬇ go to that line on the terminal, clear it, and update it
╭────────╮
│Terminal│
╰────────╯
This separation of concerns is unnecessary and makes it difficult to
understand where and when the terminal is updated. This approach also
makes it somewhat challenging to change the way in which the display
interacts with the terminal, as both the display renderer and the
message renderer need to e.g. understand terminal dimensions, movement,
etc.
These changes reimplement the interactive Progress Renderer using a
frame-oriented approach. The display is updated at 60 frame per second.

Decouple persist and display events (#15709)
<!---
Thanks so much for your contribution! If this is your first time
contributing, please ensure that you have read the
[CONTRIBUTING](https://github.com/pulumi/pulumi/blob/master/CONTRIBUTING.md)
documentation.

# Description
Retry #15529 with fix for the issue that required the revert in #15705
This removes a scenario where events could not be persisted to the cloud
because they were waiting on the same event being displayed
Instead of rendering the tree every time a row is updated, instead, this
renders when the display actually happens in the the `frame` call. The
renderer instead simply marks itself as dirty in the `rowUpdated`,
`tick`, `systemMessage` and `done` methods and relies on the frame being
redrawn on a 60Hz timer (the `done` method calls `frame` explicitly).
This makes the rowUpdated call exceedingly cheap (it simply marks the
treeRenderer as dirty) which allows the ProgressDisplay instance to
service the display events faster, which prevents it from blocking the
persist events.
This requires a minor refactor to ensure that the display object is
available in the frame method
Because the treeRenderer is calling back into the ProgressDisplay object
in a goroutine, the ProgressDisplay object needs to be thread safe, so a
read-write mutex is added to protect the `eventUrnToResourceRow` map.
The unused `urnToID` map was removed in passing.
## Impact
There are scenarios where the total time taken for an operation was
dominated by servicing the events.
This reduces the time for a complex (~2000 resources) `pulumi preview`
from 1m45s to 45s
For a `pulumi up` with `-v=11` on a the same stack, where all the
register resource spans were completing in 1h6m and the
postEngineEventBatch events were taking 3h45m, this PR removes the time
impact of reporting the events (greatly inflated by the high verbosity
setting) and the operation takes the anticipated 1h6m
<!--- Please include a summary of the change and which issue is fixed.
Please also include relevant motivation and context. -->
Fixes #15668
This was happening because the renderer was being marked dirty once per
second in a tick event, which caused frame to redraw. There is a check
in the render method that `display.headerRow` is not nil that was
previously used to prevent rendering when no events had been added. This
check is now part of the `markDirty` logic
Some of the tests needed to be updated to make this work and have also
been refactored
## Checklist
- [X] I have run `make tidy` to update any new dependencies
- [X] I have run `make lint` to verify my code passes the lint check
- [ ] I have formatted my code using `gofumpt`
<!--- Please provide details if the checkbox below is to be left

This separation of concerns is unnecessary and makes it difficult to
understand where and when the terminal is updated. This approach also
makes it somewhat challenging to change the way in which the display
interacts with the terminal, as both the display renderer and the
message renderer need to e.g. understand terminal dimensions, movement,
etc.
These changes reimplement the interactive Progress Renderer using a
frame-oriented approach. The display is updated at 60 frame per second.
If nothing has happened to invalidate the display's contents (i.e. no
changes to the terminal geometry or the displayable contents have occurred),
then the frame is not redrawn. Otherwise, the contents of the display
are re-rendered and redrawn.
An advantage of this approach is that it made it relatively simple to
fix a long-standing issue with the interactive display: when the number
of rows in the output exceed the height of the terminal, the new
renderer clamps the output and allows the user to scroll the tree table
using the up and down arrow keys.

Decouple persist and display events (#15709)

[CONTRIBUTING](https://github.com/pulumi/pulumi/blob/master/CONTRIBUTING.md)
documentation.

# Description
Retry #15529 with fix for the issue that required the revert in #15705
This removes a scenario where events could not be persisted to the cloud
because they were waiting on the same event being displayed
Instead of rendering the tree every time a row is updated, instead, this
renders when the display actually happens in the the `frame` call. The
renderer instead simply marks itself as dirty in the `rowUpdated`,
`tick`, `systemMessage` and `done` methods and relies on the frame being
redrawn on a 60Hz timer (the `done` method calls `frame` explicitly).
This makes the rowUpdated call exceedingly cheap (it simply marks the
treeRenderer as dirty) which allows the ProgressDisplay instance to
service the display events faster, which prevents it from blocking the
persist events.
This requires a minor refactor to ensure that the display object is
available in the frame method
Because the treeRenderer is calling back into the ProgressDisplay object
in a goroutine, the ProgressDisplay object needs to be thread safe, so a
read-write mutex is added to protect the `eventUrnToResourceRow` map.
The unused `urnToID` map was removed in passing.
## Impact
There are scenarios where the total time taken for an operation was
dominated by servicing the events.
This reduces the time for a complex (~2000 resources) `pulumi preview`
from 1m45s to 45s
For a `pulumi up` with `-v=11` on a the same stack, where all the
register resource spans were completing in 1h6m and the
postEngineEventBatch events were taking 3h45m, this PR removes the time
impact of reporting the events (greatly inflated by the high verbosity
setting) and the operation takes the anticipated 1h6m
<!--- Please include a summary of the change and which issue is fixed.
Please also include relevant motivation and context. -->
Fixes #15668
This was happening because the renderer was being marked dirty once per
second in a tick event, which caused frame to redraw. There is a check
in the render method that `display.headerRow` is not nil that was
previously used to prevent rendering when no events had been added. This
check is now part of the `markDirty` logic
Some of the tests needed to be updated to make this work and have also
been refactored
## Checklist

- [ ] I have formatted my code using `gofumpt`
<!--- Please provide details if the checkbox below is to be left

[cli] Reimplement the interactive renderer
The display pipleline looks like this:
╭──────╮
│Engine│
╰──────╯
⬇ engine events
╭────────────────╮
│Progress Display│
╰────────────────╯
⬇ display events: ticks, resource updates, system messages
╭─────────────────╮
│Progress Renderer│
╰─────────────────╯
⬇ text
╭────────╮
│Terminal│
╰────────╯
The existing implementation of the interactive Progress Renderer is broken
into two parts, the display renderer and the message renderer. The display
renderer converts display events into progress messages, each of which
generally represents a single line of text at a particular position in
the output. The message renderer converts progress messages into screen
updates by identifying whether or not the contents of a particular
message have changed and if so, re-rendering its output line. In
somewhat greater detail:
╭────────────────╮
│Display Renderer│
╰────────────────╯
⬇ convert resource rows into a tree table
⬇ convert the tree table and system messages into lines
⬇ convert each line into a progress message with an index
╭────────────────╮
│Message Renderer│
╰────────────────╯
⬇ if the line identified in a progress message has changed,
⬇ go to that line on the terminal, clear it, and update it
╭────────╮
│Terminal│
╰────────╯
This separation of concerns is unnecessary and makes it difficult to
understand where and when the terminal is updated. This approach also
makes it somewhat challenging to change the way in which the display
interacts with the terminal, as both the display renderer and the
message renderer need to e.g. understand terminal dimensions, movement,
etc.
These changes reimplement the interactive Progress Renderer using a
frame-oriented approach. The display is updated at 60 frame per second.
If nothing has happened to invalidate the display's contents (i.e. no
changes to the terminal geometry or the displayable contents have occurred),
then the frame is not redrawn. Otherwise, the contents of the display
are re-rendered and redrawn.
An advantage of this approach is that it made it relatively simple to
fix a long-standing issue with the interactive display: when the number
of rows in the output exceed the height of the terminal, the new
renderer clamps the output and allows the user to scroll the tree table
using the up and down arrow keys.

Decouple persist and display events (#15709)

# Description
Retry #15529 with fix for the issue that required the revert in #15705
This removes a scenario where events could not be persisted to the cloud
because they were waiting on the same event being displayed
Instead of rendering the tree every time a row is updated, instead, this
renders when the display actually happens in the the `frame` call. The
renderer instead simply marks itself as dirty in the `rowUpdated`,
`tick`, `systemMessage` and `done` methods and relies on the frame being
redrawn on a 60Hz timer (the `done` method calls `frame` explicitly).
This makes the rowUpdated call exceedingly cheap (it simply marks the
treeRenderer as dirty) which allows the ProgressDisplay instance to
service the display events faster, which prevents it from blocking the
persist events.
This requires a minor refactor to ensure that the display object is
available in the frame method
Because the treeRenderer is calling back into the ProgressDisplay object
in a goroutine, the ProgressDisplay object needs to be thread safe, so a
read-write mutex is added to protect the `eventUrnToResourceRow` map.
The unused `urnToID` map was removed in passing.
## Impact
There are scenarios where the total time taken for an operation was
dominated by servicing the events.
This reduces the time for a complex (~2000 resources) `pulumi preview`
from 1m45s to 45s
For a `pulumi up` with `-v=11` on a the same stack, where all the
register resource spans were completing in 1h6m and the
postEngineEventBatch events were taking 3h45m, this PR removes the time
impact of reporting the events (greatly inflated by the high verbosity
setting) and the operation takes the anticipated 1h6m
<!--- Please include a summary of the change and which issue is fixed.
Please also include relevant motivation and context. -->
Fixes #15668
This was happening because the renderer was being marked dirty once per
second in a tick event, which caused frame to redraw. There is a check
in the render method that `display.headerRow` is not nil that was
previously used to prevent rendering when no events had been added. This
check is now part of the `markDirty` logic
Some of the tests needed to be updated to make this work and have also
been refactored
## Checklist

- [X] I have run `make lint` to verify my code passes the lint check
- [ ] I have formatted my code using `gofumpt`

into two parts, the display renderer and the message renderer. The display
renderer converts display events into progress messages, each of which
generally represents a single line of text at a particular position in
the output. The message renderer converts progress messages into screen
updates by identifying whether or not the contents of a particular
message have changed and if so, re-rendering its output line. In
somewhat greater detail:
╭────────────────╮
│Display Renderer│
╰────────────────╯
⬇ convert resource rows into a tree table
⬇ convert the tree table and system messages into lines
⬇ convert each line into a progress message with an index
╭────────────────╮
│Message Renderer│
╰────────────────╯
⬇ if the line identified in a progress message has changed,
⬇ go to that line on the terminal, clear it, and update it
╭────────╮
│Terminal│
╰────────╯
This separation of concerns is unnecessary and makes it difficult to
understand where and when the terminal is updated. This approach also
makes it somewhat challenging to change the way in which the display
interacts with the terminal, as both the display renderer and the
message renderer need to e.g. understand terminal dimensions, movement,
etc.
These changes reimplement the interactive Progress Renderer using a
frame-oriented approach. The display is updated at 60 frame per second.
If nothing has happened to invalidate the display's contents (i.e. no
changes to the terminal geometry or the displayable contents have occurred),
then the frame is not redrawn. Otherwise, the contents of the display
are re-rendered and redrawn.
An advantage of this approach is that it made it relatively simple to
fix a long-standing issue with the interactive display: when the number
of rows in the output exceed the height of the terminal, the new
renderer clamps the output and allows the user to scroll the tree table
using the up and down arrow keys.

Decouple persist and display events (#15709)

# Description
Retry #15529 with fix for the issue that required the revert in #15705
This removes a scenario where events could not be persisted to the cloud
because they were waiting on the same event being displayed
Instead of rendering the tree every time a row is updated, instead, this
renders when the display actually happens in the the `frame` call. The
renderer instead simply marks itself as dirty in the `rowUpdated`,
`tick`, `systemMessage` and `done` methods and relies on the frame being
redrawn on a 60Hz timer (the `done` method calls `frame` explicitly).
This makes the rowUpdated call exceedingly cheap (it simply marks the
treeRenderer as dirty) which allows the ProgressDisplay instance to
service the display events faster, which prevents it from blocking the
persist events.
This requires a minor refactor to ensure that the display object is
available in the frame method
Because the treeRenderer is calling back into the ProgressDisplay object
in a goroutine, the ProgressDisplay object needs to be thread safe, so a
read-write mutex is added to protect the `eventUrnToResourceRow` map.
The unused `urnToID` map was removed in passing.
## Impact
There are scenarios where the total time taken for an operation was
dominated by servicing the events.
This reduces the time for a complex (~2000 resources) `pulumi preview`
from 1m45s to 45s
For a `pulumi up` with `-v=11` on a the same stack, where all the
register resource spans were completing in 1h6m and the
postEngineEventBatch events were taking 3h45m, this PR removes the time
impact of reporting the events (greatly inflated by the high verbosity
setting) and the operation takes the anticipated 1h6m
<!--- Please include a summary of the change and which issue is fixed.
Please also include relevant motivation and context. -->
Fixes #15668
This was happening because the renderer was being marked dirty once per
second in a tick event, which caused frame to redraw. There is a check
in the render method that `display.headerRow` is not nil that was
previously used to prevent rendering when no events had been added. This
check is now part of the `markDirty` logic
Some of the tests needed to be updated to make this work and have also
been refactored
## Checklist

- [ ] I have formatted my code using `gofumpt`
<!--- Please provide details if the checkbox below is to be left

Add display to the engine tests (#16050)
We want to add more test coverage to the display code. The best way to
do that is to add it to the engine tests, that already cover most of the
pulumi functionality.
It's probably not really possible to review all of the output, but at
least it gives us a baseline, which we can work with.
There's a couple of tests that are flaky for reasons I don't quite
understand yet. I marked them as to skip and we can look at them later.
I'd rather get in the baseline tests sooner, rather than spending a
bunch of time looking at that. The output differences also seem very
minor, so not super concerning.
The biggest remaining issue is that this doesn't interact well with the
Chdir we're doing in the engine. We could either pass the CWD through,
or just try to get rid of that Chdir. So this should only be merged
after https://github.com/pulumi/pulumi/pull/15607.
I've tried to split this into a few commits, separating out adding the
testdata, so it's hopefully a little easier to review, even though the
PR is still quite large.
One other thing to note is that we're comparing that the output has all
the same lines, and not that it is exactly the same. Because of how the
engine is implemented, there's a bunch of race conditions otherwise,
that would make us have to skip a bunch of tests, just because e.g.
resource A is sometimes deleted before resource B and sometimes it's the
other way around.
The biggest downside of that is that running with `PULUMI_ACCEPT` will
produce a diff even when there are no changes. Hopefully we won't have
to run that way too often though, so it might not be a huge issue?

[cli] Reimplement the interactive renderer
The display pipleline looks like this:
╭──────╮
│Engine│
╰──────╯
⬇ engine events
╭────────────────╮
│Progress Display│
╰────────────────╯
⬇ display events: ticks, resource updates, system messages
╭─────────────────╮
│Progress Renderer│
╰─────────────────╯
⬇ text
╭────────╮
│Terminal│
╰────────╯
The existing implementation of the interactive Progress Renderer is broken
into two parts, the display renderer and the message renderer. The display
renderer converts display events into progress messages, each of which
generally represents a single line of text at a particular position in
the output. The message renderer converts progress messages into screen
updates by identifying whether or not the contents of a particular
message have changed and if so, re-rendering its output line. In
somewhat greater detail:
╭────────────────╮
│Display Renderer│
╰────────────────╯
⬇ convert resource rows into a tree table
⬇ convert the tree table and system messages into lines
⬇ convert each line into a progress message with an index
╭────────────────╮
│Message Renderer│
╰────────────────╯
⬇ if the line identified in a progress message has changed,
⬇ go to that line on the terminal, clear it, and update it
╭────────╮
│Terminal│
╰────────╯
This separation of concerns is unnecessary and makes it difficult to
understand where and when the terminal is updated. This approach also
makes it somewhat challenging to change the way in which the display
interacts with the terminal, as both the display renderer and the
message renderer need to e.g. understand terminal dimensions, movement,
etc.
These changes reimplement the interactive Progress Renderer using a
frame-oriented approach. The display is updated at 60 frame per second.
If nothing has happened to invalidate the display's contents (i.e. no
changes to the terminal geometry or the displayable contents have occurred),
then the frame is not redrawn. Otherwise, the contents of the display
are re-rendered and redrawn.
An advantage of this approach is that it made it relatively simple to
fix a long-standing issue with the interactive display: when the number
of rows in the output exceed the height of the terminal, the new
renderer clamps the output and allows the user to scroll the tree table
using the up and down arrow keys.

Decouple persist and display events (#15709)

# Description
Retry #15529 with fix for the issue that required the revert in #15705
This removes a scenario where events could not be persisted to the cloud
because they were waiting on the same event being displayed
Instead of rendering the tree every time a row is updated, instead, this
renders when the display actually happens in the the `frame` call. The
renderer instead simply marks itself as dirty in the `rowUpdated`,
`tick`, `systemMessage` and `done` methods and relies on the frame being
redrawn on a 60Hz timer (the `done` method calls `frame` explicitly).
This makes the rowUpdated call exceedingly cheap (it simply marks the
treeRenderer as dirty) which allows the ProgressDisplay instance to
service the display events faster, which prevents it from blocking the
persist events.
This requires a minor refactor to ensure that the display object is
available in the frame method
Because the treeRenderer is calling back into the ProgressDisplay object
in a goroutine, the ProgressDisplay object needs to be thread safe, so a
read-write mutex is added to protect the `eventUrnToResourceRow` map.
The unused `urnToID` map was removed in passing.
## Impact
There are scenarios where the total time taken for an operation was
dominated by servicing the events.
This reduces the time for a complex (~2000 resources) `pulumi preview`
from 1m45s to 45s
For a `pulumi up` with `-v=11` on a the same stack, where all the
register resource spans were completing in 1h6m and the
postEngineEventBatch events were taking 3h45m, this PR removes the time
impact of reporting the events (greatly inflated by the high verbosity
setting) and the operation takes the anticipated 1h6m
<!--- Please include a summary of the change and which issue is fixed.
Please also include relevant motivation and context. -->
Fixes #15668
This was happening because the renderer was being marked dirty once per
second in a tick event, which caused frame to redraw. There is a check
in the render method that `display.headerRow` is not nil that was
previously used to prevent rendering when no events had been added. This
check is now part of the `markDirty` logic
Some of the tests needed to be updated to make this work and have also
been refactored
## Checklist

[cli] Reimplement the interactive renderer
The display pipleline looks like this:
╭──────╮
│Engine│
╰──────╯
⬇ engine events
╭────────────────╮
│Progress Display│
╰────────────────╯
⬇ display events: ticks, resource updates, system messages
╭─────────────────╮
│Progress Renderer│
╰─────────────────╯
⬇ text
╭────────╮
│Terminal│
╰────────╯
The existing implementation of the interactive Progress Renderer is broken
into two parts, the display renderer and the message renderer. The display
renderer converts display events into progress messages, each of which
generally represents a single line of text at a particular position in
the output. The message renderer converts progress messages into screen
updates by identifying whether or not the contents of a particular
message have changed and if so, re-rendering its output line. In
somewhat greater detail:
╭────────────────╮
│Display Renderer│
╰────────────────╯
⬇ convert resource rows into a tree table
⬇ convert the tree table and system messages into lines
⬇ convert each line into a progress message with an index
╭────────────────╮
│Message Renderer│
╰────────────────╯
⬇ if the line identified in a progress message has changed,
⬇ go to that line on the terminal, clear it, and update it
╭────────╮
│Terminal│
╰────────╯
This separation of concerns is unnecessary and makes it difficult to
understand where and when the terminal is updated. This approach also
makes it somewhat challenging to change the way in which the display
interacts with the terminal, as both the display renderer and the
message renderer need to e.g. understand terminal dimensions, movement,
etc.
These changes reimplement the interactive Progress Renderer using a
frame-oriented approach. The display is updated at 60 frame per second.
If nothing has happened to invalidate the display's contents (i.e. no
changes to the terminal geometry or the displayable contents have occurred),
then the frame is not redrawn. Otherwise, the contents of the display
are re-rendered and redrawn.
An advantage of this approach is that it made it relatively simple to
fix a long-standing issue with the interactive display: when the number
of rows in the output exceed the height of the terminal, the new
renderer clamps the output and allows the user to scroll the tree table
using the up and down arrow keys.

[cli] Reimplement the interactive renderer
The display pipleline looks like this:
╭──────╮
│Engine│
╰──────╯
⬇ engine events
╭────────────────╮
│Progress Display│
╰────────────────╯
⬇ display events: ticks, resource updates, system messages
╭─────────────────╮
│Progress Renderer│
╰─────────────────╯
⬇ text
╭────────╮
│Terminal│
╰────────╯
The existing implementation of the interactive Progress Renderer is broken
into two parts, the display renderer and the message renderer. The display
renderer converts display events into progress messages, each of which
generally represents a single line of text at a particular position in
the output. The message renderer converts progress messages into screen
updates by identifying whether or not the contents of a particular
message have changed and if so, re-rendering its output line. In
somewhat greater detail:
╭────────────────╮
│Display Renderer│
╰────────────────╯
⬇ convert resource rows into a tree table
⬇ convert the tree table and system messages into lines
⬇ convert each line into a progress message with an index
╭────────────────╮
│Message Renderer│
╰────────────────╯
⬇ if the line identified in a progress message has changed,
⬇ go to that line on the terminal, clear it, and update it
╭────────╮
│Terminal│
╰────────╯
This separation of concerns is unnecessary and makes it difficult to
understand where and when the terminal is updated. This approach also
makes it somewhat challenging to change the way in which the display
interacts with the terminal, as both the display renderer and the
message renderer need to e.g. understand terminal dimensions, movement,
etc.
These changes reimplement the interactive Progress Renderer using a
frame-oriented approach. The display is updated at 60 frame per second.
If nothing has happened to invalidate the display's contents (i.e. no
changes to the terminal geometry or the displayable contents have occurred),
then the frame is not redrawn. Otherwise, the contents of the display
are re-rendered and redrawn.
An advantage of this approach is that it made it relatively simple to
fix a long-standing issue with the interactive display: when the number
of rows in the output exceed the height of the terminal, the new
renderer clamps the output and allows the user to scroll the tree table
using the up and down arrow keys.

Decouple persist and display events (#15709)
<!---
Thanks so much for your contribution! If this is your first time
contributing, please ensure that you have read the
[CONTRIBUTING](https://github.com/pulumi/pulumi/blob/master/CONTRIBUTING.md)
documentation.
-->
# Description
Retry #15529 with fix for the issue that required the revert in #15705
This removes a scenario where events could not be persisted to the cloud
because they were waiting on the same event being displayed
Instead of rendering the tree every time a row is updated, instead, this
renders when the display actually happens in the the `frame` call. The
renderer instead simply marks itself as dirty in the `rowUpdated`,
`tick`, `systemMessage` and `done` methods and relies on the frame being
redrawn on a 60Hz timer (the `done` method calls `frame` explicitly).
This makes the rowUpdated call exceedingly cheap (it simply marks the
treeRenderer as dirty) which allows the ProgressDisplay instance to
service the display events faster, which prevents it from blocking the
persist events.
This requires a minor refactor to ensure that the display object is
available in the frame method
Because the treeRenderer is calling back into the ProgressDisplay object
in a goroutine, the ProgressDisplay object needs to be thread safe, so a
read-write mutex is added to protect the `eventUrnToResourceRow` map.
The unused `urnToID` map was removed in passing.
## Impact
There are scenarios where the total time taken for an operation was
dominated by servicing the events.
This reduces the time for a complex (~2000 resources) `pulumi preview`
from 1m45s to 45s
For a `pulumi up` with `-v=11` on a the same stack, where all the
register resource spans were completing in 1h6m and the
postEngineEventBatch events were taking 3h45m, this PR removes the time
impact of reporting the events (greatly inflated by the high verbosity
setting) and the operation takes the anticipated 1h6m
<!--- Please include a summary of the change and which issue is fixed.
Please also include relevant motivation and context. -->
Fixes #15668
This was happening because the renderer was being marked dirty once per
second in a tick event, which caused frame to redraw. There is a check
in the render method that `display.headerRow` is not nil that was
previously used to prevent rendering when no events had been added. This
check is now part of the `markDirty` logic
Some of the tests needed to be updated to make this work and have also
been refactored
## Checklist
- [X] I have run `make tidy` to update any new dependencies
- [X] I have run `make lint` to verify my code passes the lint check
- [ ] I have formatted my code using `gofumpt`
<!--- Please provide details if the checkbox below is to be left
unchecked. -->
- [X] I have added tests that prove my fix is effective or that my
feature works
<!---
User-facing changes require a CHANGELOG entry.
-->
- [ ] I have run `make changelog` and committed the
`changelog/pending/<file>` documenting my change
<!--
If the change(s) in this PR is a modification of an existing call to the
Pulumi Cloud,
then the service should honor older versions of the CLI where this
change would not exist.
You must then bump the API version in
/pkg/backend/httpstate/client/api.go, as well as add

[cli] Reimplement the interactive renderer
The display pipleline looks like this:
╭──────╮
│Engine│
╰──────╯
⬇ engine events
╭────────────────╮
│Progress Display│
╰────────────────╯
⬇ display events: ticks, resource updates, system messages
╭─────────────────╮
│Progress Renderer│
╰─────────────────╯
⬇ text
╭────────╮
│Terminal│
╰────────╯
The existing implementation of the interactive Progress Renderer is broken
into two parts, the display renderer and the message renderer. The display
renderer converts display events into progress messages, each of which
generally represents a single line of text at a particular position in
the output. The message renderer converts progress messages into screen
updates by identifying whether or not the contents of a particular
message have changed and if so, re-rendering its output line. In
somewhat greater detail:
╭────────────────╮
│Display Renderer│
╰────────────────╯
⬇ convert resource rows into a tree table
⬇ convert the tree table and system messages into lines
⬇ convert each line into a progress message with an index
╭────────────────╮
│Message Renderer│
╰────────────────╯
⬇ if the line identified in a progress message has changed,
⬇ go to that line on the terminal, clear it, and update it
╭────────╮
│Terminal│
╰────────╯
This separation of concerns is unnecessary and makes it difficult to
understand where and when the terminal is updated. This approach also
makes it somewhat challenging to change the way in which the display
interacts with the terminal, as both the display renderer and the
message renderer need to e.g. understand terminal dimensions, movement,
etc.
These changes reimplement the interactive Progress Renderer using a
frame-oriented approach. The display is updated at 60 frame per second.
If nothing has happened to invalidate the display's contents (i.e. no
changes to the terminal geometry or the displayable contents have occurred),
then the frame is not redrawn. Otherwise, the contents of the display
are re-rendered and redrawn.
An advantage of this approach is that it made it relatively simple to
fix a long-standing issue with the interactive display: when the number
of rows in the output exceed the height of the terminal, the new
renderer clamps the output and allows the user to scroll the tree table
using the up and down arrow keys.
