mysql - Delta Indexing by timestamp in Sphinx -


i attempting setup main+delta index scheme using timestamp field instead of max_doc_id in example in docs.

source main {     sql_query_pre   = \     replace sph_counter (counter_id, last_update_time) values (1, now())  sql_query       = \     select id, filename, absolute_path, last_update_time \     files \     last_update_time <= ( select last_update_time sph_counter counter_id=1) }  source delta { sql_query       = \     select id, filename, absolute_path, last_update_time \     files \     last_update_time > ( select last_update_time sph_counter counter_id=1)  sql_query_pre   = }

the indexing , merging works intended, sql_query_pre main source never updates last_update_time in sph_counter table.

i unsure problem might be.

i running doing following:

re-index delta       (every 30 seconds)

and:

merge delta main    (every 10 mins) re-index delta       (after merge)

am wrong in thinking merge run sql_query_pre update sph_counter last_update_time?

am wrong in thinking merge run sql_query_pre update sph_counter last_update_time?

yes. during merge sphinx not run of queries 'source' indexes. doesnt read information config file, apart getting location of index files.

the simplest way, have delta index update (seperate) counter, sql_query_pre.

then during right after merge, can copy timestamp delta record main record.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
