Run mb_convert_encoding in ALL cases to remove potentially invalid UTF-8 characters.
Add the "replacement" UTF-8 character to the whitespace array to ensure it's removed.
Don't assume that other data from a PDF is the same as the content. Bypasses some still-unfixed PDFParser encoding issues.
Also exit the crawler script if we are in debug mode and there is a crawl already running.
Make 's_show_orphans' a runtime variable and normalize the SQL queries it's used in.
Also change generic '$select' variable to more semantic '$crawldata'.
Add a third value to the sp_progress config value to let the script know if a crawl was resumed or not.
Also restore the sp_sha1 data from the crawltemp table on a resumed crawl.
If an orphan URL is blocked by a user rule, then remove it from the 'sp_exist' list so it doesn't keep coming back again and again. This only happens the next crawl after the user adds new rules.
Other misc edits.
Automatically encode/decode json when saving/reading ODATA config values.
Remove 'sp_links_crawled' config table value, now stored in 'sp_progress'.
Update Crawl Information window in real-time while crawler is running. Be more aggressive at reloading the page to get the latest data once a crawl has finished.
Time the setting of certain config values while crawling in a more sensible way.
Allow downloading of the page index as a csv.
Remove unnecessary database columns url_base and status_noindex
Store list of domains at crawl so we don't need to request them every page-load; you will need to reinstall fresh because of this change
Don't require reloading the page after a crawl has completed.
Javascript will dynamically update the Crawler Information values if we are on the Crawler Management page.
If admin UI is loaded while a crawl is not running, add a ping every 5 seconds to check if one has started. Fix issue where reloading the page while a crawl was running would cause a JS error that would cancel the crawl.
Keep Page Index pagination page within limits; add UTF-8 BOM to CSV and TXT download output; use utf8mb4_unicode_520_ci collation to remove need for SQL REGEXP; add more latin accent equivalent characters.
