Add a "maxbyte" param as a control variable #5

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Currently there is no option to limit download by a cumulative maximum
amount of bytes. The file limit as of now only implements a maximum limit
on the size of a single URL.

Implement a "maxbyte" param which will monitor the maximum net download
size and end the crawl when it reaches the limit. 

Specifications
--------------
1. Param part of control:limits section.
2. Should accept plain numbers and also KB, MB and GB.
     For example.

    <maxbytes value="5000" /> - End crawl at 5000 bytes
    <maxbytes value="10kb" /> - End crawl at 10kb 
    <maxbytes value="50MB" /> - End crawl at 50 MB.
     <maxbytes value="1GB" /> - End crawl at 1 GB.

The value should accept strings like "5 kb", "5kb", "5.0KB",
"5 KB" etc. In other words spaces and case are ignored.

Hint: Use a regular expression for parsing this param's value. Let me know if 
you
need help.

Done 95%, need to implement logic to stop threads from saving data to disk after
controller kills them.

Verified. 
 <maxbytes value="300kb"/>
 <maxbandwidth value="30"/>
Final
 HarvestMan mirror foo completed in 18.46 seconds.
[00:01:00] 169 links scanned in 1 server .
[00:01:00] 11 files written.
[00:01:00] 409728  bytes received at the rate of 21.67 KB/sec .
[00:01:00] 292887  bytes were written to disk.

Thanks. That worked. It is time to download some websites at 5kb per second for 
few
hours. The config settings are working.
