QUESTION

fetch stream html like ajax onprogress

Asked 2021-Jun-09 at 00:43

is it possible to do simple simple modification to this ?

the goal if to "draw" the html as it's being received.

possible scenario : a php that takes 5 to 8 seconds to execute, and push every echo while processing.

The regular fetch.then is WAITING for all lines to BEGIN the render.

I would like that it begins to render AS SOON as the data comes in.

I have nginx with output buffer off so that every echo is pushed to the browser lines (i don't have to wait for the completion of the php to start seeing the echos...) when I hit this php in a browser, I see live all lines appearing, but fetch is waiting for all lines.

here the regular fetch.then (working but waits)

Uint8Array to string in Javascript

Here a mix and tested

the php can push ANY html with CSS AND javascript that will be executable as soon as it arrives YAY ;)

The test on the php was echo some html, echo '1', sleep(3) and repear a couple times.

when I trigger that "fetchsrteam" function, I see each echo live streamed, I don't have to wait to the completion of the php. That way i can see feedbacks of what's going on (rare but possible) long php scripts that retreive info from APIs, do stuff, compute, etc.

You use .toDataURL() to encode that huge image as a lossless .png file. That probably generates a multimegabyte string that you try to POST. Somewhere along the way Safari probably runs out of contiguous RAM and gacks, either on allocation or garbage collection. It's also likely your POST's payload size exceeds php's maximum.

Try .toDataURL('image/jpeg', 0.3) to get a low-quality JPEG image, which will generate a much smaller string. If that works, crank up the quality (0.3 to 0.4, 0.5, etc).

Or, better, convert your canvas to a binary Blob, then post that. It will take less space than a data URL. Something like this. Not, repeat not, debugged.

QUESTION

Is _mm_prefetch asynchronous? Profiling shows a lot of cycles on it

Asked 2021-Jan-23 at 10:55

I understood that _mm_prefetch() causes the requested value to be fetched into processor's cache, and my code will be executed while something pre-fetches.

However, my VS2017 profiler states that 5.7% is spent on the line that accesses my cache and 8.63% on the _mm_prefetch line. Is the profiler mistaken? If I am waiting for the data to be fetched, what do I need it for? I could wait in the next function call, when I need it...

On the other hand, the overall timing shows significant benefit of that prefetch call.

So the question is: is the data being fetch asynchronously?

Additional information.

I have multiple caches, for various key width, up to 32-bit keys (that I am currently profiling). The access to cache and pre-fetching are extracted into separate __declspec(noinline) functions to isolate them from surrounding code.

Substantially everything on an out-of-order CPU is "asynchronous" in the way you describe (really, running in parallel and out of order). In that sense, prefetch isn't really different than regular loads, which can also run out of order or "async" with other instructions.

Once that is understood, the exact behavior of prefetch is hardware dependent, but it is my observation that:

On Intel, prefetch instructions can retire before their data arrives. So a prefetch instruction that successfully begins execution won't block the CPU pipeline after that. However, note "successfully executes": the prefetch instruction still requires a line fill buffer (MSHR) if it misses in L1 and on Intel it will wait for that resource if not available. So if you issue a lot of prefetch misses in parallel, they end up waiting for fill buffers which makes them act quite similarly to vanilla loads in that scenario.
On AMD Zen [2], prefetches do not wait for a fill buffer if none is available. Presumably, the prefetch is simply dropped. So a large number of prefetch misses behave quite differently than Intel: they will complete very quickly, regardless if they miss or not, but many of the associated lines will not actually be fetched.

QUESTION

Empty Pivot Cache when creating a pivot table in VBA

Asked 2020-Apr-21 at 20:59

I'm using code from https://excelchamps.com/blog/vba-to-create-pivot-table/ to create a pivot table in a long macro I'm writing. The pivot table recently stopped working; this sub runs with no errors but there is no sign of the pivot table. Was fully functional until recently. On trying to troubleshoot I've found the PCache variable is empty, I'm assuming this is where everything is breaking down. The only thing changed since this was working is I changed the cell formats of two columns in the data range for the pivot table, however they seem irrelevant and are not being used for the pivot table.

I have also recorded my own macro to try and fix this. Manually creating the pivot table works fine but this is not a solution to my problem. The recorded macro from this does not work however. I have tried code from multiple different sites as well and have used non-variable ranges but nothing has worked.

The reason you're not getting an error is that you've included an On Error statement, which masks any errors. If you comment out or delete that line, you'll get an error here...

QUESTION

VBA Excel file size containing multiple pivot tables is huge

Asked 2020-Apr-01 at 18:03

I am automating the process of creating pivot tables in excel. The problem I have is that the pivot tables I create using my macro is way larger than the ones I create manually. Both of the pivot tables look identical but there is a great difference in file size.

As seen in the image above, the one created by my macro is about 6 times larger! I suspect that it is the way I cache for the data when creating my pivot tables. So, here is the general code I use to create my pivot tables.
