-
-F site.name main feed file
- opened/created, then written, by innd
- read by duct
- unlinked by duct
- tokens blanked out by duct when processed
- site.name_lock lock preventing multiple ducts
- to hold lock must open,F_SETLK[W]
- and then stat to check that locked file
- still has name site.name_lock
- holder of this lock is "duct"
- (only) lockholder may remove the lockfile
-D site.name_flushing temporary feed file during flush (or crash)
- hardlink created by duct
- unlinked by duct
- site.name_defer 431'd articles, still being written,
- created, written, used by duct
-
- site.name_backlog.<date>.<inum>
- 431'd articles, ready for innxmit or duct
- created (link/mv) by duct
- site.name_backlog<anything-else> (where <anything-else> does not
- contain '#' or '~') eg
- site.name_backlog.manual
- anything the sysadmin likes (eg, feed files
- from old feeds to be merged into this one)
- created (link/mv) by admin
- may be symlinks (in which case links
- may be written through, but only links
- will be removed.
-
- It is safe to remove backlog files manually,
- if it's desired to throw away the backlog.
-
-Backlog files are also processed by innduct. We find the oldest
-backlog file which is at least a certain amount old, and feed it
-back into our processing. When every article in it has been read
-and processed, we unlink it and look for another backlog file.
-
-If we don't have a backlog file that we're reading, we close the
-defer file that we're writing and make it into a backlog file at
-the first convenient opportunity.
