bug: opening a preview for an embedded PDF can take over a minute and a half

[jceipek]

Describe the bug I'm helping a friend analyze the results of a FOIA request. The data from the request was delivered in the form of several 30-300MB PDF portfolios, each with a few dozen to a few hundred embedded PDFs of emails. Datashare does a great job of identifying each of the embedded emails, but clicking on the preview button results in a white preview box that can stay blank for >1.5min.

To Reproduce Given a local Datashare instance containing a PDF portfolio, steps to reproduce the behavior:

1. Launch Datashare locally from the app icon
2. Click on 1st under Extraction levels in the Filter pane
3. Click on a document in the search pane
4. Click on the Preview tab.
5. Notice that the preview tab is white.
6. Wait 1.5 min.
7. Notice that the preview tab contains a PDF preview.

Expected behavior Launching Acrobat Reader (a very slow program) and opening one of the emails in a 300MB PDF portfolio takes around 5 seconds. I expect that previewing a local embedded PDF in local Datashare should take no more than that time, and certainly not more than 18x as long.

• Browser: Reproducible in Firefox, Edge, Safari
• Version: 14.0.4 - 2024

Hello Julian, thanks for reporting the issue.

This is no a bug from Datashare, it is own your web browser are configured. You could switch to the build-in PDF viewer which is much more lightweight than Acrobat Reader: https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-another-viewer

We have plan to improve the extraction pipeline for documents so each page of the PDF can be treated separately (with generation of static artifacts for each documents, like image preview). Unfortunately it's gonna take time so I advice you either switch to a different PDF viewer or split your files with pdfseparate or something similar.

Hi @pirhoo, unfortunately, I don't think it's how my web browsers are configured. For example, under "Applications" in about:preferences in Firefox, I see "Open in Firefox" as the action for "Portable Document Format (PDF)". If I open one of my PDF portfolios using file:/// in the browser, the file takes at most a few seconds to load and clicking on an embedded email to open it feels instantaneous. On the other hand, when I click the Preview tab in Datashare, the Datashare terminal window spews a lot of information (see below for an example), sometimes for over a minute and a half, before I see anything in the Preview pane. If my browser can display an embedded email many times faster than Datashare, I think the problem must lie with whatever Datashare is doing to preview PDFs. It's worth noting that previewing root documents also takes a long time, so the problem doesn't seem to be limited to previewing embedded PDFs.

Re using a tool like pdfseparate, I have so far been unable to find a tool that preserves the metadata of the PDF portfolios I have. pdfseparate does nothing at all to a PDF portfolio. pdfdetach is better but it fails to extract all the emails in a portfolio in cases where the individual emails have similar subjects. Additionally, it destroys critical metadata like when the emails were sent. I've managed to write a script for Acrobat Reader that extracts the information I most need, but security limitations in Acrobat mean that it requires a manual step per document, and after that, I'm not sure how I would associate the extracted metadata with the files for use in Datashare (or how to make that process easy enough for my nontechnical friend). Directly importing the PDF portfolios into Datashare is ideal because it inherently preserves the needed metadata and is able to index embedded emails and email attachments.

Example output when clicking preview on an embedded document in Datashare:

For more evidence that this is related to Datashare, I took a network profile while opening a document preview. This one "only" took 23 seconds, but I think the preview is only useful if it takes < 5 seconds; ideally much less time. From the recording, you can see that the network tab shows a 22.53 seconds "waiting for server" period for a 709 kB response. I imagine that this either means that the local server is much slower than it should be to prepare the response or to transfer it to the browser:

I'm closing this one until we redesigned the way we store embedded artifacts.
