Subject: [PATCH] sd-journal: return SD_JOURNAL_INVALIDATE only if journal
|
|
|
a19bc6 |
files were actually deleted/moved (#5580)
|
|
|
a19bc6 |
|
|
|
a19bc6 |
When caller invokes sd_journal_open() we usually open at least one
|
|
|
a19bc6 |
directory with journal files. add_root_directory() function increments
|
|
|
a19bc6 |
current_invalidate_counter. After sd_journal_open() returns
|
|
|
a19bc6 |
current_invalidate_counter != last_invalidate_counter.
|
|
|
a19bc6 |
|
|
|
a19bc6 |
After caller waits for journal events (e.g. waits for new messages in
|
|
|
a19bc6 |
journal) then it usually calls sd_journal_process(). However, on first
|
|
|
a19bc6 |
call to sd_journal_process(), function determine_change() returns
|
|
|
a19bc6 |
SD_JOURNAL_INVALIDATE even though no journal files were
|
|
|
a19bc6 |
deleted/moved. This is because current_invalidate_counter !=
|
|
|
a19bc6 |
last_invalidate_counter.
|
|
|
a19bc6 |
|
|
|
a19bc6 |
After the fix we make sure counters has the same value before we begin
|
|
|
a19bc6 |
processing inotify events.
