adblock2privoxy's Issues

rsync: link_stat "/root/adblock2privoxy*" failed: No such file or directory (2)

After executing rsync -a ./adblock2privoxy* /usr/local/etc/adblock2privoxy, an error message appears:
rsync: link_stat "/root/adblock2privoxy*" failed: No such file or directory (2)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1207) [sender=3.1.3]

version string of filter is truncated if it not composed only of digits

This may be trivial, but in case it is somehow connected to #15 seems wise to report it as well
adblock_anty-dotacje.txt version is 100.2 and adblock2privoxy allows only digits. As the result it truncates the version to 100
adblock_adguard.txt current version is 364.2 and result in file is 364

EDIT: Looking at the source version number is treated as Integer which must be a whole number. Probably switching here to floating point is required to accept digits after dot.

empty rules

I am not sure how should converter behave in such a cases, but if the rule is not possibile to convert into privoxy understood regex than pehaps it is better to skip it with error message instead of creating an empty rule?

Examples

{+client-header-tagger{ab2p-block-dnt-R390} \
}
# |http://$subdocument,third-party,domain=clictune.com (onelist.txt: 39648)

add support pre-processor directives for filters

AdguardTeam/AdguardBrowserExtension#917

Filters are not taken effect

Hope you can help me.
I have followed the manual to integrate the filter files into the privoxy proxy.
To automatically generate these filters I have generated a little pull request (see #33).
It seems the the filters are loaded without any error, but I do not really see an effect on the homepages at all.
I have also used a separate apache server to use the css files, but there is no change seen here in improving the filters. Also I cannot see any requests from the proxy to the apache.

New feature: duplicate detection

It would be beneficial for privoxy to deal with as few records as possible which would than lead to faster processing. One of the ways to accomplish it is to limit number of created rules. From below example it is obvious that if rules ||displaymarketplace.com^ and ||disqusads.com^ completely block hosts under all circumstances than the rest of the rules may be safely skipped as they would have no effect beyond what the main rule does. At the moment all entries are processed and added to the list by the converter. Same goes for whitelisting rule starting with @@||

||displaymarketplace.com^
||displaymarketplace.com^$third-party
||disqusads.com^
||disqusads.com/ads-iframe/adsnative/
||disqusads.com/ads-iframe/prebid/
||disqusads.com^$third-party

A bit harder example where combining entries into one would also help reducing number of similar entries.

||directrev.com^$popup
||directrev.com^$popup,image,media,object,object-subrequest,other,ping,script,stylesheet,subdocument,websocket,xmlhttprequest
||directrev.com^$third-party

Yet another example that could use simplification to the (_|/)dropdown_ad. entry.

_dropdown_ad.
/dropdown_ad.

Less common case as hosts are expected to end with ^, but converting only the second entry would be beneficial in this case. They are used separately by adblock2privoxy increasing the number of rules without any actual gain

||events.reddit.com
||events.reddit.com^

Double rules on filters are too broad

Converter creates double rules on some filter sets which lead to unintended blocks.

For example czech ruleset for instance from record /emonitor. creates

# /emonitor. (filters.txt: 35)
/(?:(*PRUNE).*?/)?emonitor\.
emonitor.*.

and polish ruleset

# /inst. (adblock_social_list.txt: 84)
/(?:(*PRUNE).*?/)?inst\.
inst.*.
# /ins. (adblock_social_list.txt: 83)
/(?:(*PRUNE).*?/)?ins\.
ins.*.
# /in. (adblock_social_list.txt: 82)
/(?:(*PRUNE).*?/)?in\.
in.*.

While the first rule for each is OK, the later is interpreted by privoxy as the rule for whole word instead of subdomain of *. In last case it leads to blocking of interia.pl which should never happen.

ab2p.common.css causes breakage on some sites

When sites are visited privoxy is sending to browser info to ask webserver for both $host.css and ab2p.common.css like in example below

192.168.101.10 - - [04/Jul/2018:10:27:31 +0200] "GET /www.wprost.pl/ab2p.css HTTP/1.1" 200 12023
192.168.101.10 - - [04/Jul/2018:10:27:31 +0200] "GET /ab2p.common.css HTTP/1.1" 200 202974
192.168.101.10 - - [04/Jul/2018:10:27:33 +0200] "GET /www.wprost.pl/ab2p.css HTTP/1.1" 200 12023
192.168.101.10 - - [04/Jul/2018:10:27:33 +0200] "GET /ab2p.common.css HTTP/1.1" 200 202974
192.168.101.10 - - [04/Jul/2018:10:27:37 +0200] "GET /emisja.contentstream.pl/ab2p.css HTTP/1.1" 200 11937

Problem is than common.css contains all the element hidding entries from all the rulesets which for some sites causes problem as it is blocking more than it should. In this particular example common file has .cookiespopup which pl/wprost/www/ab2p.css does not have as it actually should not hence no ruleset said it should. Unintended effect is that causes whole website to completely disappear in the browser.

Ideal situation would be that browser asks for ab2p.common.css only if $host.css does not exist. Could that be acomplished by adblock2privoxy, privoxy or the webserver?

converter does not recognise rules with leading TAB

It turns out there are filters such as this one which for readability start off with leading tab. Adblock2privoxy creates many empty rules for those leading to privoxy block almost anything rendering Internet useless.

As workaround to this I used below code which downloads ruleset locally and prepares it for adblock2privoxy prior to being used by converter.

wget https://raw.githubusercontent.com/maciejtarmas/AlleBlock/master/alleblock.txt
sed -i -e 's/^[ \t]*//' alleblock.txt
adblock2privoxy http://local.website.com/alleblock.txt

I am not sure how should that be implemented in converter, but booking at the code the I found out InputParser.hs has following

lineSpaces :: Parser ()
lineSpaces = skipMany (satisfy isLineSpace) <?> "white space"
    where isLineSpace c = c == ' ' || c == '\t'

Maybe some changes to include tabs there could take care of this?

/(*PRUNE).*?

Converter translates rule to the best of abilities it has at the moment, but in this case that simply means that just about any rules used for blocking domain components would actually get trough due to being whitelisted by this record :(

That probably would not be best solution, but would it not be better to tranlate the rule to spec-komp.com/(*PRUNE).*? instead of what is currently done?

css hide rules created for HTTPS sides do not work for LAN users

ab2p.system.filter contain following rule for element hiding.

cat ab2p.system.filter |grep http
s@.*\sHTTP\/1.*@$&\r\nX-Frame-Options: DENY@i
s@[^'"\s]\s*<head[^>]*>(?=\s*[^'"\s])@$&<link rel="stylesheet" type="text/css" href="http://192.168.101.101:8445/ab2p.common.css"></link><link rel="stylesheet" type="text/css" href="http://192.168.101.101:8445/$host/ab2p.css"></link>@iUD
s@[^'"\s]\s*<head[^>]*>(?=\s*[^'"\s])@$&<link rel="stylesheet" type="text/css" href="http://192.168.101.101:8445/debug/ab2p.common.css"></link><link rel="stylesheet" type="text/css" href="http://192.168.101.101:8445/$host.debug/ab2p.css"></link>@iUD

It works for HTTP sites but does not work for HTTPS sites which got decrypted by MITM for privoxy to filter. It is due to browsers not allowing mixed content for HTTPS sites for targets other than localhost.

I tried preparing local webserver in SSL and switching all 4 links to href="https://192.168.101.101:8445, but it seems not to work either as information about https content is not send to browser at all. It also seems to break regular HTTP sites.

The site https://projects.zubr.me/wiki/adblock2privoxyDownloads does not open

Actually the subject. And it seems apache2 has stayed in the old configuration.

element hidding whitelists undesired behaviour

To decrease element hiding directory quite substantialy I removed from filter lists all rules starting with ## to rely only on rules dedicated for particular sites. It turned out each file still had over ~150 entries not related to the site. They came from element hidding exception rules
eg. ~tv.mail.ru##.js-springs__top instead of only removing .js-springs__top for that particular site it also installed it for every other site (about 80 000 of them). While I undestard logic behind it I do not think it should be done if there is no ##.js-springs__top to match entries for all sites.

css file could use new line for site specific rules

There filters using advanced hiding rules which are site specific. See example 1 or 2. I am no HTML expert, but my gut feeling says in such cases one probably would benefit more if converter sends such records having rules located in parenthesis into the separate line instead of placing it in default which only has {display:none!important;visibility:hidden!important}

adblock2privoxy segmentation fault

Using following filter causes crash. It used to work and still seems to work on its own, but recently for about past two weeks or so when I use my script composed of several filter sets during preparation of css files it fails due to segmentation fault.

I do not know what entry is responsible for that, but I made sure that no other filter set is making adblock2privoxy fail.

Perhaps you need to run 'stack init'?

unintended escape characters for [ and ]

I discovered that adding escape characters by the converter before brackets leads to not working rule as privoxy would than expect those characters to be present literally in the link which obviously would not happen

This adblock rule ||mypage.com/dl/201[7-8]-[0-1][0-9]/[3-4][0-9][0-9][0-9]

is translated to the ^mypage\.com/dl/201\[7-8\]-\[0-1\]\[0-9\]/\[3-4\]\[0-9\]\[0-9\]\[0-9\]

while it should be ^mypage\.com/dl/201[7-8]-[0-1][0-9]/[3-4][0-9][0-9][0-9] as only that would catch link as http://mypage.com/dl/2017-10/4014

easylist go.*. rule breaks many sites

Taking care of double rules is not enough as there even single rules which by using .*. break more sites than intended

}
# |http://go.$domain=nowvideo.sx (easylist.txt: 46984)
go.*.

Following is setting header for sites as imasdk.googleapis.com

WORKAROUND:
Use sed -i -e '/^go\.\*\./s/^/#/' /etc/privoxy/ab2p.action to disable this rule

P.S. Rulesets I created after all fixes/workarounds so far still use .*. ~1200 times. Almost all other actually seem less harmless with exception of promo.*. wich does come from easylist.txt as well.

Using ghcup to install haskell instead of stack solved my issues of installation.

TODO: remove matched element conversion

One of the element hiding features in list works with the use of ##^ https://github.com/gorhill/uBlock/wiki/Static-filter-syntax#html-filters

In part it is related to the #12 but may be used with out it if only ##^ combination is translated into the rule which would remove line containing that information during the filtering. At least it should work for records as example.com##^.badstuff

PPB_uBlock_AdGuard.txt has several sites which make use of this feature.

My guess is it should work in privoxy as it works using inling stuff, but test I have done for 4fun.tv##^#cModal actually failed so discovery of proper line would be required before actual converter implementation

removeelement.filter

SERVER-HEADER-FILTER: removeelement
s@#cModal@@i
s@id="cModal"@@i

removeelement.action

{+server-header-filter{removeelement}}
^4fun\.tv

translated records get dot in front which has adverse effects

||www.twojapogoda.pl/templates/rodo/rodo.js - original
.www.twojapogoda.pl/templates/rodo/rodo\.js - converted
Rule has no effect unless it has no dot in the front

||log. - original
.log.*. - converted
It was intended to block pages as log.mypage.com but blocks pages as krolowasuperstarblog.wordpress.com.

My idea to fix both of those cases is to add ^ in front instead of . as this stands for start of the string in regular expression and I tested that it works in both of those cases properly.

expired rules are not used

When I tried to use following filter to convert strangely no filter rules nor element hiding css files got created.

adblock2privoxy -p /tmp/privoxy -w /tmp/privoxy/www -d 192.168.101.101:8445 -t privoxy_ab2b.task \
https://raw.githubusercontent.com/KonoromiHimaries/PolishSubFilters/master/internal-filters/headers/headery.txt

task file did not yield any errors either.

adblock2privoxy erros out on several recods

Using https://easylist-downloads.adblockplus.org/easylistpolish.txt among others there is quite a few records on which adblock2privoxy errors out. Would it be possible to fix them?

unblock rules too unspecific for certain sites

https://easylist-downloads.adblockplus.org/easyprivacy.txt uses ||ria.ru/js/counter.js while
https://easylist-downloads.adblockplus.org/advblock.txt uses @@||ria.ru^$generichide
This leads to following combination

In file: ab2p.action View
--
{+add-header{DNT: 1} } .ria.ru/js/counter\.js
{ } .ria.ru/js/counter\.js
{+block{adblock rules} +server-header-tagger{ab2p-block-s} } .ria.ru/js/counter\.js
{ } .ria.ru
{+client-header-tagger{ab2p-unblock-dnt-R1636} } /(*PRUNE).*?
{-filter{ab2p-elemhide-filter} } .ria.ru
{+client-header-tagger{ab2p-unblock-elem-R1636} } /(*PRUNE).*?
{-block +client-header-tagger{ab2b-unblock-u} -server-header-tagger{ab2p-block-s} +server-header-tagger{ab2p-unblock-d} +server-header-tagger{ab2p-unblock-s} } .ria.ru
{-block +client-header-tagger{ab2p-unblock-request-Ai-Ci-when-R5458t} } /(*PRUNE).*?

Converter works fine for both as rules get created as intended for both records. Problem is however that using whitelist is meant only for element hidding while generated privoxy record allows all traffic for that site including counter which should be blocked as easyprivacy.txt record intended.

In case like that seems it is better to not create / remove ru/ria/ab2p.css instead creating too generic filter which would also disable other filters.

Workaround before using that filter with adblock2privoxy hashout all generichide whitelistings from the filter list using sed -i -e '/@@||/{/generichide/s/^/#/}' advblock.txt

css directories and webserver

Why not use privoxy's user-manual folder?
Put css files in there then use http://p.p/user-manual/$host.css in filters can do the same job without webserver.

Add badfilter support

Rules with badfilter should be used to eliminate bad rules.

https://github.com/gorhill/uBlock/wiki/Static-filter-syntax#badfilter

This is needed to use https://github.com/uBlockOrigin/uAssets/blob/master/filters/unbreak.txt

Installation: stack command fails with "specified targets matched no packages"

Attempting a first-time install on ubuntu 22.04. The installation instructions did not mention that users need to clone the adblock2privoxy repo first, and then run the script in the README.me from within the cloned repository. However, once I figured that out, I found that this installation failed at the "stack" phase. The stack error is:

stack install --local-bin-path /usr/local/bin --allow-different-user
Error: [S-8506]
Error parsing targets: The specified targets matched no packages.
Perhaps you need to run 'stack init'?

I then ran stack init but that gave the error:

Error: [S-2422]
       Snapshot https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/lts/20/10.yaml does not have all the packages to match
       your requirements.

           parsec-permutation not found
               - adblock2privoxy requires >=0.1.2.0

       This may be resolved by:
       * Using --omit-packages to exclude mismatching package(s).
       * Using --resolver to specify a matching snapshot/resolver.

And does not resolve the specified targets matched no packages error.

conversion errors - not abp specific

Issue 6 is about errors that are related to adblock specific extensions. I tried to see if there are any errors not related to those records and I got number of 53 cases reported with cat privoxy_ab2b.task |grep ERROR|grep -v -E -i -a 'abp-|errors'|wc
Seems they should be much easier to fix and probably require only slight change in the code itself to make it work

privoxy crash due to bad filter combination

Running command adblock2privoxy -p /tmp/privoxy -w /tmp/privoxy -d 127.0.0.1:8445 -t privoxy_ab2b.task \ https://easylist-downloads.adblockplus.org/easylist.txt even with only one source creates among others ab2p.system.action file. That file includes:

#workaround for gzip handling privoxy bugs
{ +prevent-compression }
 *.yahoo.com
 *.amazon.com

This results in privoxy crash if config files created got overridden on running app or fails to start if it was not previously running
