css - What happened to `column-span: <integer>` -

searching functionality, came across 2001 draft, specified column-span defined none | | <integer> | inherit. don’t none (spans no columns? mean display:none‽), other that, it’s nice. comes useful picture.

code sth. along lines of:

article { column-count: 3 } h1 { column-span: } h2 { column-span: 2 }

a bit history: abolished in 2005. 2007, re-introduced values 1 | all, wich became none | all 2011 (reintroducting nonsensical none).

my question: why property badly curtailed? there reasoning behind that? (and behind none)

in current draft @ least, property name column-span means “spans several columns” , value none means “no” or “false.” in december 2009 draft, things more natural, property interpreted “number of columns spanned” , initial value 1 , not none.

in general, identifiers in css misleading , may reflect various stages of planning—think white-space, affects line breaking in general, not text, or letter-spacing, affects characters, not letters.

based on have read in various discussions, reason limiting values 2 (no spanning, spanning all) implementing other values different , more complicated. moreover, demand such feature appears considerably more limited basic functionality.

this sounds realistic, since basic multi-column layout has poor support: don’t think major browser supports under proposed standard names (but back upwards under browser-specific property names), , there not seem back upwards column-span: all under name. (rumors safari supports it, tests on win 7 version don’t confirm this.)

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
