Add file size columns to download status table

[ANAMASGARD]

Fixes #249

Summary

Adds file size information (total_MB, mean_MB, and rows) to the download status table, helping users understand disk usage for each geom.

Problem

Currently, the download status table shows how many TSV files need to be downloaded, but doesn't show file sizes. Users can't see if they're downloading 1MB or 100MB.

Test output:

Only added the test case in this first commit in the next commit will try to fix the issue !

Add download size info to status table (#249)

Adds total_MB, mean_MB, and rows columns to the download status table. Calculates total data size and row count for each geom by iterating through all downloaded chunks. Handles both array and object data structures. Values update as data is downloaded and displayed.

Browser screenshot verification included showing new columns working.

Thanks! This is a good start. I see the result below using https://github.com/animint/animint2/blob/master/inst/examples/WorldBank-paper.R

Can you please make the following changes?

• remove selected chunk and status columns
• right justify numeric columns
• remove mean MB column
• combine downloaded and total columns into one column named "files" value "4/52"
• same for MB and rows, value should be " # downloaded / # possible "
• This data viz, for geom3 and geom4, makes 52 numbered chunk files (chunk1 to chunk52.tsv) plus a chunk_common.tsv file. Currently the common file is counted for the numbr downloaded "4" but not for the total number "52" but we should change so that the common file is counted for both. (and for each attribute, files/MB/rows)

please click Resolve so I can see which previous comments you have already addressed

[tdhock]

can you please post a screenshot like this one https://github.com/animint/animint2/pull/272#issuecomment-3473335127 but created with the new code?

[ANAMASGARD]

Sir @tdhock Here's the updated screenshot with the new download status table format:

Changes implemented:

• ✅ Removed "selected chunk" and "status" columns
• ✅ Removed "mean MB" column
• ✅ Combined columns into "files", "MB", and "rows" format (downloaded/total)
• ✅ Right-justified all numeric columns
• ✅ Common chunk now counted in BOTH downloaded and total for all metrics

All values update correctly as data downloads, and common chunk is properly counted in both downloaded and total counts.

Please give your feedback and suggest what changes I need to make so that the failing test can be passed on the GitHub , Thank You !

https://github.com/animint/animint2/pull/272#issuecomment-3538898963 seems to have the wrong old screenshot, please revise

[ANAMASGARD]

Updated screenshot with WorldBank-paper.R example showing new download status table format:

• "files", "MB", and "rows" columns in "downloaded/total" format
• Removed "selected chunk", "status", and "mean MB" columns
• Right-justified numeric columns
• Common chunk counted in both downloaded and total counts

[tdhock]

that new screenshot looks good, thanks! please fix test failures.

[ANAMASGARD]

• Added id="download_status" to the table element for test discovery
• Added initial display values ("0 / X" format) for files, MB, and rows columns

The remaining test failures in CI (ghpages permission issues, knit-print duplicate IDs) are unrelated to this PR's download status table changes.

[tdhock]

this needs to be fixed

── Failure ('test-renderer3-knit-print.R:67:3'): id property is unique over entire page ──
Expected `length(not.unique)` to equal 0.

using this branch I see

• large number of rows would benefit from having commas, like 4,321 instead of 4321 -- can you please fix?
• sometimes 0.00 is displayed for MB which could be confusing. I'm not sure what the best fix for this would be. Either change to 0 (without .00) or change column heading to "disk space" and use KB or MB in each row (depending on how big they are).

also please change the computation or column name "MB" to be consistent with "man du" which says

       The SIZE argument is an integer and optional unit (example: 10K is
       10*1024).  Units are K,M,G,T,P,E,Z,Y,R,Q (powers of 1024) or
       KB,MB,... (powers of 1000).  Binary prefixes can be used, too:
       KiB=K, MiB=M, and so on.

in the example above we see 15.62 MB for geom2. but looking at the file sizes in R we see:

> sum(size.dt[grep("geom2",name), R_bytes/1000/1000])
[1] 16.38009
> sum(size.dt[grep("geom2",name), R_bytes/1024/1024])
[1] 15.62127

15.62 is the number you get when you divide by 1024, which should be MiB (not MB as currently written in column header) so please

• change MB to MiB in header, or
• change divisor from 1024 to 1000

thanks!

[ANAMASGARD]

• Updated NEWS/DESCRIPTION to version 2025.12.4 with the final download table description.
• Download status table now shows files/disk/rows in “downloaded / total”, rows use commas, disk uses KiB/MiB (1024 divisor, man du consistent), and all numeric columns are right‑aligned.
• Tests now target rendered HTML (headers and alignment) and are passing; full CI (JS/R/CRAN) is green.

Sir @tdhock can you please again review this PR .

[ANAMASGARD]

Sir @tdhock Updated screenshot showing the new download status table format:

[tdhock]

the updated screenshot looks better, thanks! it would be easier to read if there were a grey or black line to separate each row/column in the table. Can you add that please?

[tdhock]

also can you please post updated screenshot?

[ANAMASGARD]

Yes Sir @tdhock I will definitely create a function and post the updated screenshot. Actually my laptop screen is broken, ASAP it is fixed I will make the changes.

[ANAMASGARD]

Sir @tdhock Updated screenshot with table borders :-

[ANAMASGARD]

Sir @tdhock The CI test failures in test-compiler-ghpages.R are not related to this PR's changes.

• The failures are caused by a race condition: both JS_coverage and R_coverage jobs run in parallel and use the same test repo (animint-test/animint2pages_test_repo), causing them to interfere with each other.

• I can fix this by making each test suite use a unique repo name based on the TEST_SUITE environment variable. Should I push that fix to this PR, or would you prefer to handle it separately (Like I raise an issue regarding this one )?

• The download status table feature is complete and working. The test failures are flaky tests that sometimes pass (run #1335 passed, #1339 failed with same code).
