> net::ERR_CONTENT_LENGTH_MISMATCH 200 (OK)

Thomas Ward, [12.04.20 19:11]
underneath the scenes that's that error

Thomas Ward, [12.04.20 19:11]
so that's whatever file cache holds the image not giving the image proper

Thomas Ward, [12.04.20 19:11]

Thomas Ward, [12.04.20 19:11]
so if the thing is S3-compatible-API backed that's the problem

Thomas Ward, [12.04.20 19:12]
and it's failing for three separate images embedded on the page

Thomas Ward, [12.04.20 19:13]
so that's beyond my ability to fix, since what this indicates is that a full bytestring was not provided and instead was a zero-length string

Thomas Ward, [12.04.20 19:13]
or similar.

Thomas Ward, [12.04.20 19:13]
from the backend

Thomas Ward, [12.04.20 19:13]
So, @tsimonq2 if this is S3-compatible-store backed then the store backing it is at fault

Dan Simmons, [12.04.20 19:14]
1910-Lubuntu-eoan-ermine.png is one of the images?

Thomas Ward, [12.04.20 19:14]
according to the embeds yes

Thomas Ward, [12.04.20 19:14]
yep, because it's showing a diff

Thomas Ward, [12.04.20 19:14]
and trying to laod the images for display

Thomas Ward, [12.04.20 19:14]
[ Photo ]

Dan Simmons, [12.04.20 19:15]
Makes sense. It is actually removed in the diff.

Thomas Ward, [12.04.20 19:15]
AND it's only erroring for certain images

Thomas Ward, [12.04.20 19:15]
and not others

Thomas Ward, [12.04.20 19:15]
yep, and that explains the error

Thomas Ward, [12.04.20 19:15]
because it's gone from the store it can no longer render the image

Dan Simmons, [12.04.20 19:15]
They would have been uploaded last release

Thomas Ward, [12.04.20 19:16]
as i said if they're gone and deleted from the S3 compatible datastore then that's the problem there

Thomas Ward, [12.04.20 19:16]
it's trying to render a file that doesn't exist anymore

Thomas Ward, [12.04.20 19:16]
HENCE the zero-length instant close of the download link and the SHA256 error

Thomas Ward, [12.04.20 19:16]
because backend is returning 0-length string to Diffusion and SHA256-HMAC can't use that

Dan Simmons, [12.04.20 19:17]
null is bad

Thomas Ward, [12.04.20 19:17]
true

Thomas Ward, [12.04.20 19:17]
so ULTIMATELY not able to be fixed by me because in reality there's nothing really *wrong* except that Phab has no functions to handle zero-length S3-returned items
