3 | =head1 NAME |
4 | |
5 | sizeme_store.pl - process and store the raw data stream from Devel::SizeMe |
6 | |
7 | =head1 SYNOPSIS |
8 | |
9 | sizeme_store.pl [--text] [--dot=sizeme.dot] [--db=sizeme.db] |
10 | |
11 | Typically used via the C<SIZEME> env var: |
12 | |
13 | export SIZEME='|./sizeme_store.pl --text' |
14 | export SIZEME='|./sizeme_store.pl --dot=sizeme.dot' |
15 | export SIZEME='|./sizeme_store.pl --db=sizeme.db' |
16 | |
17 | =head1 DESCRIPTION |
18 | |
19 | Reads the raw memory data from Devel::SizeMe and processes the tree |
20 | via a stack, propagating data such as totals, up the tree nodes. |
21 | Output completed nodes in the request formats. |
22 | |
23 | The --text output is similar to the textual representation output by the module |
24 | when the SIZEME env var is set to an empty string. |
25 | |
26 | The --dot output is suitable for feeding to Graphviz. (On OSX the Graphviz |
27 | application will be started automatically.) |
28 | |
29 | The --db output is a SQLite database. The db schema is very subject to change. |
30 | This output is destined to be the primary one. The other output types will |
31 | probably become separate programs that read the db. |

35 | # Needs to be generalized to support pluggable output formats. |
d81c4128 |
36 | # Actually it needs to be split so sizeme_store.pl only does the store |
37 | # and another program drives the output with plugins. |
d3b8a135 |
38 | # Making nodes into (lightweight fast) objects would be smart. |
39 | # Tests would be even smarter! |
40 | # |
41 | # When working on this code it's important to have a sense of the flow. |
42 | # Specifically the way that depth drives the completion of nodes. |
43 | # It's a depth-first stream processing machine, which only ever holds |
44 | # a single stack of the currently incomplete nodes, which is always the same as |
45 | # the current depth. I.e., when a node of depth N arrives, all nodes >N are |
46 | # popped off the stack and 'completed', each rippling data up to its parent. |
