so you can write x <- failure_or_result(); y <- failure_or_result(); return op(x, y); and the compiler will generate appropriate things to propagate errors |

How large? And if one wants one page, they decompress whole large warc? |

how large depends on how big the file from the crawler is |

they use a different gzip stream per file with a cdx to tell them where to seek and start decompressing |

It does make sense if you have enough space to store it in simple format, yes. Still deflate with preseed dictionary would make it lot more (for html, or even images (headers)...) efficient adding next to no change, as zlib that is the standard for gzip, is standard and deflate is just gzip withotu header. |

yakfish: Maybe it was written in way that is confused soft and hard parts. Not sure |
17:55
🔗
|
yipdw_ |
a preseed dictionary might improve compression ratio, but it would also complicate access |
17:55
🔗
|
yipdw_ |
if you lose the dictionary -- whether it be a separate file, or a separate part of the stream -- you're in trouble |
17:55
🔗
|
yipdw_ |
one advantage of concatenated gzipped warc records is that you have many ways to access that stream, and you can recover parts of it without much hassle |
17:56
🔗
|
yipdw_ |
so you need to balance that in too. accessibility is a major concern alongside storage efficiency |
17:57
🔗
|
Yoshimura |
yipdw_: Well I meant same way, per record deflate, of course. |
17:58

if you can benchmark this and demonstrate significant gains on typical datasets that would be interesting |

yipdw_ |
Wayback Machine, pywb, webarchiveplayer are some examples |
17:59

|
Yoshimura |
And dictionary would be a standard thing that should not be lost. If the warc was compressed in way, that only body of webpage would be gzipped in final format, so you could just stream that chunk to browser it would make sense. |
17:59
🔗
|
yipdw_ |
please do investigate |
18:00
🔗
|
Yoshimura |
But if its whole warc and you do not replay whole headers, means you still need to decompress, and that would make other (potentially time expensive, but very efficient (xdelta)) compression much better. |
18:00
🔗
|
Yoshimura |
But if you still want to keep speed plus almost total compatibility (same library, different calls) then deflate would be the way. I will. |

All found is that it tests the gzip files and uses gzip for that. |
18:14
🔗
|
Yoshimura |
Which is honestly retarded. |
18:15
🔗
|
Yoshimura |
As it has to spawn a lot of processes, and the warc files are tiny, so I can see most time spent on spawning the processes then on actual tests. |
18:17

Yoshimura |
All the other gzip operations are handled via python via zlib and they are only used for json metadata. So the README.md could be in false statement or misleading. |

Not sure about capability of python, but in best case it would take only single process and would reuse handle to the library for each warc record. |

Yoshimura |
In the worse case, it would re-init the library handles. |

And also while I dislike python personally, one has to ask himself why the whole megawarc-factory is not scripted, perhaps in python, using workers with thread safe operations for the queues. |

So after going through the info, I conclude that gzip is nice, while deflate with dictionary and a new tools (one, different languages) would add little complexity for potentially great benefits (to be determined experimentally with crappy amateur with insight dictionary). Those tools would be mere wrappers for zlib, just like gzip. Which only has |
18:45
🔗
|
Yoshimura |
additional header. In this case plus dictionary, that would be elaborately selected over time by group of experts with input from amateurs over the world. So given in context of time, there could be only one universal dictionary for course of many, many years. Or optionally even language specific ones, or framework relative ones. ... Basically this |
18:45
🔗
|
Yoshimura |
process would be same like HTTP/2, which does use predefined dictionary to compress HTTP headers and both save BW and improve latency at the same time. |

🔗
|
Yoshimura |
It does iterate over warc records, unless I misunderstood. |
18:49

Yoshimura |
So pigz has no place there, also its made to test the file for errors. So I would only use gzip or zlib. |
18:50
🔗
|
Yoshimura |
If space was concern over CPU, xdelta or per-line diff could be incorporated, having per-site specific dictionaries. Which could be made HTTP/1.1 SDCH extension compatible. ... This could be a great thing with great potential for personal or small scale archiving. But if someone does not care about space or money much, the deflate would be enough. |

In time though CPU power is getting cheaper, while storage goes marginally down. |

what's a "custom WARC"? |
21:01
🔗
|
Yoshimura |
I did read stuff, not shole spec. |
21:02
🔗
|
arkiver |
JW_work: I mean like stuffing some headers and data you found somewhere in a WARC |
21:02
🔗
|
joepie91 |
Yoshimura: right. so one thing to take into consideration, aside from recommending that you read the full spec, is that not all responses are necessarily HTTP |
21:02
🔗
|
joepie91 |
for example, Heritrix also writes DNS requests and responses to the WARC |
21:02
🔗
|
joepie91 |
WARC is more-or-less agnostic to what exact kind of data it contains |
21:03
🔗
|
joepie91 |
Yoshimura: there's a few subtleties like this, plus the unusual requirements of long-term archival, that make it somewhat difficult to design new/compatible implementations |
21:03
🔗
|
joepie91 |
Yoshimura: also, I -think- the index file implementation that IA uses is not part of the WARC spec |
21:04
🔗
|
joepie91 |
not sure what limitations that introduces |
21:04
🔗
|
joepie91 |
docs-wise, there's https://archive.org/web/researcher/cdx_file_format.php and https://archive.org/web/researcher/cdx_legend.php and some stuff that can be inferred from code like https://github.com/joepie91/node-cdx |

21:06
🔗
|
joepie91 |
Yoshimura: point is, .warc.gz is pretty much a fixed format in and of itself, in part due to the cdx files |

Yoshimura: for example, the cdx contains offsets of the compressed data |

Ungzipping over http range is honorable, but it does include the warc headers, so pretty useless. Also gzip is http capability, not needed part. |

joepie91 |
Yoshimura: not sure what you mean |
21:18

Gzip is used for whole record, including warc header. |

But if you want to serve it as file you need to process first. |

So gzip over http is half useless. |

the gzip is a technical property, not a feature |

I suspect in a couple of decades, if costs/gb fail to decline fast enough, IA may be a lot more interested in de-duplication; but at this point I think computing power is not sufficiently cheap (as compared with storage) to make it worth it. |
