A tool for displaying and manipulating Private Web Archive Web Request+Response (pwebarc WRR) files of Private Web Archive (pwebarc) project
Project description
What?
wrrarms
(pwebarc-wrrarms
) is a tool for displaying and manipulating Private Web Archive (pwebarc) Web Request+Response (WRR) files produced by pWebArc browser extension.
Quickstart
Installation
- Install with:
pip install pwebarc-wrrarms
and run aswrrarms --help
- Alternatively, install it via Nix
nix-env -i -f ./default.nix
- Alternatively, run without installing:
python3 -m wrrarms --help
Building a hierarchy of latest versions of all URLs
Assuming you keep your WRR dumps in ~/pwebarc/raw
you can generate a wget
-like file hierarchy of symlinks under ~/pwebarc/latest
pointing to the latest version of each URL in ~/pwebarc/raw
with
wrrarms organize --action symlink-update --output hupq --to ~/pwebarc/latest --and "status|== 200C" ~/pwebarc/raw
or, using a bit better format:
wrrarms organize --action symlink-update --output hupnq --to ~/pwebarc/latest --and "status|== 200C" ~/pwebarc/raw
Personally, I prefer the flat
format as I dislike deep file hierarchies and it allows to see and filter new dumps more easily in ranger
file browser:
wrrarms organize --action symlink-update --output flat --to ~/pwebarc/latest --and "status|== 200C" ~/pwebarc/raw
If you have a lot of WRR files all of the above commands could be rather slow, so if you want to keep your tree updated in real-time you should use a two-stage --stdin0
pipeline shown in the examples section below instead.
Previewing WRR files
See wrrarms-xdg-open
script for a way to xdg-open
.wrr
files.
See wrrarms-w3m
script for an example of how you can use wrrarms
and w3m
to turn your WRR files containing HTML pages into readable plain-text.
There is also wrrarms-pandoc
script that does the same via pandoc
.
See the scripts sub-directory for more examples.
TODO
-
Rendering into static website mirrors a-la
wget -k
.Currently, the extension archives everything except WebSockets data but
wrrarms
+pandoc
only work well for dumps of mostly plain text websites (which is the main use case I use this whole thing for: scrape a website and then mass-convert everything to PDFs via somepandoc
magic, then index those withrecoll
). -
Converter from
mitmproxy
dumps, HAR, WARC, and PCAP files into WRR. -
Converter from WRR to WARC.
-
Data deduplication.
-
Non-dumb server with time+URL index and replay, i.e. a local Wayback Machine.
-
Full text indexing and search.
Usage
wrrarms
A tool to pretty-print, compute and print values from, search, organize (programmatically rename/move/symlink/hardlink files), (WIP: check, deduplicate, and edit) pWebArc WRR (WEBREQRES, Web REQuest+RESponse) archive files.
Terminology: a reqres
(Reqres
when a Python type) is an instance of a structure representing HTTP request+response pair with some additional metadata.

: only work on reqres which match any of these expressions...--and EXPR
: ... and all of these expressions, both can be specified multiple times, both use the same expression format aswrrarms get --expr
, which see
wrrarms get

: terminate output values with\0
(NUL) bytes
wrrarms run
Compute output values by evaluating expressions EXPR
s for each of NUM
reqres stored at PATH
s, dump the results into into newly generated temporary files (terminating each value as specified), spawn a given COMMAND
with given arguments ARG
s and the resulting temporary file paths appended as the last NUM
arguments, wait for it to finish, delete the temporary files, exit with the return code of the spawned process.

wrrarms organize
Rename/hardlink/symlink given WRR files to DESTINATION
based on their metadata.
Operations that could lead to accidental data loss are not permitted.
E.g. wrrarms organize --action rename
will not overwrite any files, which is why the default --output
contains %(num)d
.

positional arguments:
PATH
: inputs, can be a mix of files and directories (which will be traversed recursively)
-
options:
--dry-run
: perform a trial run without actually performing any changes-q, --quiet
: don't log computed updates to stderr-a {rename,hardlink,symlink,symlink-update}, --action {rename,hardlink,symlink,symlink-update}
: organize how:rename
: rename source files underDESTINATION
, will fail if target already exists (default)hardlink
: create hardlinks from source files to paths underDESTINATION
, will fail if target already existssymlink

--batch-number INT
: batch at most this many--action
s together (default:1024
), making this larger improves performance at the cost of increased memory consumption, setting it to zero will force all--action
s to be applied immediately--lazy
: sets--batch-number
to positive infinity; most useful in combination with--action symlink-update
in which case it will forcewrrarms
to compute the desired file system state first and then perform disk writes in a single batch-o FORMAT, --output FORMAT

Examples
-
Pretty-print all reqres in
../dumb_server/pwebarc-dump
using an abridged (for ease of reading and rendering) verbose textual representation:wrrarms pprint ../dumb_server/pwebarc-dump
-
Pipe response body from a given WRR file to stdout:
wrrarms get ../dumb_server/pwebarc-dump/path/to/file.wrr
-
Get first 4 characters of a hex digest of sha256 hash computed on the URL without the fragment/hash part:
wrrarms get -e "net_url|sha256|prefix 4" ../dumb_server/pwebarc-dump/path/to/file.wrr
-
Pipe response body from a given WRR file to stdout, but less efficiently, by generating a temporary file and giving it to
cat
:wrrarms run cat ../dumb_server/pwebarc-dump/path/to/file.wrr
Thus
wrrarms run
can be used to do almost anything you want, e.g.wrrarms run less ../dumb_server/pwebarc-dump/path/to/file.wrr
wrrarms run -- sort -R ../dumb_server/pwebarc-dump/path/to/file.wrr
wrrarms run -n 2 -- diff -u ../dumb_server/pwebarc-dump/path/to/file-v1.wrr ../dumb_server/pwebarc-dump/path/to/file-v2.wrr
-
List paths of all WRR files from
../dumb_server/pwebarc-dump
that contain only complete200 OK
responses with bodies larger than 1K:wrrarms find --and "status|== 200C" --and "response.body|len|> 1024" ../dumb_server/pwebarc-dump
-
Rename all WRR files in
../dumb_server/pwebarc-dump/default
according to their metadata using--output default
(see thewrrarms organize
section for its definition, thedefault
format is designed to be human-readable while causing almost no collisions, thus makingnum
substitution parameter to almost always stay equal to0
, making things nice and deterministic):wrrarms organize ../dumb_server/pwebarc-dump/default
alternatively, just show what would be done
wrrarms organize --dry-run ../dumb_server/pwebarc-dump/default
-
The output of
wrrarms organize --zero-terminated
can be piped intowrrarms organize --stdin0
to perform complex updates. E.g. the following will rename new reqres from../dumb_server/pwebarc-dump
to~/pwebarc/raw
renaming them with--output default
, thefor
loop is there to preserve profiles:for arg in ../dumb_server/pwebarc-dump/* ; do wrrarms organize --zero-terminated --to ~/pwebarc/raw/"$(basename "$arg")" "$arg" done > changes
then, we can reuse
changes
to symlink all new files from~/pwebarc/raw
to~/pwebarc/all
using--output hupq_msn
, which would show most of the URL in the file name:wrrarms organize --stdin0 --action symlink --to ~/pwebarc/all --output hupq_msn < changes
and then, we can reuse
changes
again and use them to update~/pwebarc/latest
, filling it with symlinks pointing to the latest200 OK
complete reqres from~/pwebarc/raw
, similar to whatwget -r
would produce (exceptwget
would do network requests and produce responce bodies, while this will build a file system tree of symlinks to WRR files in/pwebarc/raw
):wrrarms organize --stdin0 --action symlink-update --to ~/pwebarc/latest --output hupq --and "status|== 200C" < changes

by dumping their whole structure into the unabridged Pythonic Object Representation (repr) format:wrrarms stream --unabridged --expr . ../dumb_server/pwebarc-dump
wrrarms stream -ue . ../dumb_server/pwebarc-dump
-
Produce a JSON list of
[<file path>, <time it finished loading in milliseconds since UNIX epoch>, <URL>]
tuples (one per reqres) and pipe it intojq
for indented and colored output:wrrarms stream --format=json -ue fs_path -e finished_at -e request.url ../dumb_server/pwebarc-dump | jq .
-
Similarly, but produce a CBOR output:
wrrarms stream --format=cbor -ue fs_path -e finished_at -e request.url ../dumb_server/pwebarc-dump | less
-
Concatenate all response bodies of all the requests in
../dumb_server/pwebarc-dump
:wrrarms stream --format=raw --not-terminated -ue "response.body|es" ../dumb_server/pwebarc-dump | less
-
Print all unique visited URLs, one per line:
wrrarms stream --format=raw --lf-terminated -ue request.url ../dumb_server/pwebarc-dump | sort | uniq
-
Same idea, but using NUL bytes while processing, and prints two URLs per line:
wrrarms stream --format=raw --zero-terminated -ue request.url ../dumb_server/pwebarc-dump | sort -z | uniq -z | xargs -0 -n2 echo
Handling binary data
Trying to use response bodies produced by wrrarms stream --format=json
is likely to result garbled data as JSON can't represent raw sequences of bytes, thus binary data will have to be encoded into UNICODE using replacement characters:
wrrarms stream --format=json -ue . ../dumb_server/pwebarc-dump/path/to/file.wrr | jq .
The most generic solution to this is to use --format=cbor
instead, which would produce a verbose CBOR representation equivalent to the one used by --format=json
but with binary data preserved as-is:
wrrarms stream --format=cbor -ue . ../dumb_server/pwebarc-dump/path/to/file.wrr | less
Or you could just dump raw response bodies separately:
wrrarms stream --format=raw -ue response.body ../dumb_server/pwebarc-dump/path/to/file.wrr | less
wrrarms get ../dumb_server/pwebarc-dump/path/to/file.wrr | less
