V Norimberku probíhá do pátku ownCloud conference 2018, tj. konference vývojářů a uživatelů open source systému ownCloud (Wikipedie) umožňujícího provoz vlastního cloudového úložiště. Přednášky lze sledovat online. Videozáznamy jsou k dispozici na YouTube. Při této příležitosti byl vydán ownCloud Server 10.0.10. Z novinek lze zdůraznit podporu PHP 7.2. Vydán byl také ownCloud Desktop Client 2.5.0. Vyzkoušet lze online demo ownCloudu.

Po třech a půl letech od vydání verze 3.4.1 byla vydána nová verze 3.4.2 programu pro filtrování spamu Apache SpamAssassin (Wikipedie). Z novinek lze zmínit 4 nové pluginy. Pravidla budou ověřována pomocí SHA-256 a SHA-512 místo SHA-1. Řešeny jsou také 4 bezpečnostní chyby. Například chyba CVE-2018-11780 v pluginu PDFInfo zneužitelná ke vzdálenému spuštění kódů (RCE).

Linus Torvalds se v oznámení o vydání 4. rc verze Linuxu 4.19 omlouvá za své chování. Posledním commitem před zvýšením rc3 na rc4 bylo odstranění souboru s Code of Conflict a přidání souboru s Contributor Covenant Code of Conduct vycházejícího z Contributor Covenant. Vývoj Linuxu 4.19 dokončí Greg Kroah-Hartman. Linus Torvalds si bere volno a bude pracovat na svém chování. Pravděpodobně vylepší svého poštovního klienta, aby mu nedovolil odesílat emaily obsahující nadávky.

Když to v bash-i ulítne - výběr komprimační metody

23.12.2012 14:42 | Přečteno: 1000× | Linux | poslední úprava: 27.12.2012 11:52

Když to bash-i ulítne. Kdo někdy programuje, tak to zná: „jen si tady něco vyzkouším na, to je prkotinka v bash-i na 10 řádků“.
Jenže ta prkotina dává nějaké informace, které chceme rozvíjet a tak je rozvíjíme, a už při délce 20 řádků začíná být jasné, že zvolený nástroj, tedy bash, není to nejlepší, ale pokračujeme…
…přece vím(e): „Jo je to naprd, bude to sice trvat 3× déle, ale když už to mám(e), přece nebudeme začínat od začátku“. A najednou tu máme 1500 řádků.
No a přesně to se mi opět stalo.
Řešil jsem už po několikáte situaci jakou komprimaci na data zvolit.
Ve spoustě případů je to fuk, a je to zbytečné to řešit - místa je dosta a je snažší navýšit kapacitu. Někdy to naráží „zlom“ (více disků se tam nevleze a pod…) a když už, tak to udělat pořádně.
bzip2 -9 je sem-tam horší než bzip2 -5, stane se i, že je gzip na tom lépe než bzip2, záleží na typu dat.
Takže když to člověk chce pořádně, tak si to zkusí a pak to aplikuje, ale ono je to docela opruz. Tak jsem si říkal, že bych si mohl udělat takový testík, který to zkusí a vyhodnotí (hlavně druhá část byla velká chyba, na to je přece tabulkový procesor).
Řešil jsem už v zásadě 3 situace:
  1. All-in-one co nejmenší. Normální archiv či záloha maximálně zkomprimovaná.
  2. Jednotlivé soubory, každý komprimovaný zvlášť (stejným typem komprese). Konkrétní případ nebudu popisovat, ale lze to přirovnat k úložišti RAW-ů (fotek), kde jsou vygenerované náhledy a je jich smečka. Každý zvlášť chceme proto, že jej chceme rychle získat, nejen rozbalit, ale i přenést.
  3. Jednotlivé složky obsahující roj dat, každá komprimovaná zvlášť. Co složka to zakázka s velkým objemem různých dat, po určité době není třeba mít data ihned po ruce, ale běžně dostupné. Jejich komprimace + přenastavení práv archivu, hezky řeší situaci, rychle a kompaktně lze data získat a zabírají méně místa.
No jak šel čas, tak mi z toho vylezl tento „skriptík“, jistě obsahující spoustu chyb, někté označené jako vlastnost.

Běžné spuštení pro test souborů všemi metodami a jejich kombinacemi:
find /absolute/path/dir -type f | ./comptest.bash -v -n 42 -w /absolute/path/to/save/dir/result.res -f

Běžné spuštení pro test adesářů (které si zataruje), jen compresí gz -9, bz-9 a 7z může vypadat nějak takto:
find /absolute/path/dir -mindepth 1 -maxdepth 1 -type d | ./comptest.bash -v -n 'e0 1 4' -w /absolute/path/to/save/dir/result.res -d

A případné opakované zobrazení výsledků:
./comptest.bash -o /absolute/path/to/save/dir/result.res
nebo
./comptest.bash -o -R 0.8 -S 8388608 /absolute/path/to/save/dir/result.res

Pro vytvořeni a uchování nejmenšího archivu:
./comptest.bash -t /directory/to/save/ -T noexistsdirname -L -n allbest1 -f /full/file/path/name
nebo pro tar adresáře
echo /full/dir/path/name | ./comptest.bash -t /directory/to/save/ -T noexistsdirname -L -n allbest1 -d

…si to vytvoří pomocnou složku (v /tmp , přestavit lze pomocí -t), kam si každý zadaný úkol připraví a otestuje (v případě -L, -l i archiv-y zanechá).
V případě úkolu 'po souboru' (-i nebo -f) si bere soubor, v případě adreářů (-d) si vytvoří tar ze zadaného adresáře. Zvláštností je, že každý cesta MUSÍ být zadána plná-absolutní (to není bug to je právě feature).
Umí to vybrat a zanechat nejmenší archiv (-L) nebo případně i všechny (-l). U menších dat nemusí být tak důležitá velikost, ale kolik zabírají bloků, což lze zadat (-b), někdy máme předvolený čas (server se třeba v noci fláká) nebo nás zajímá kompresní poměr, tak je lze zadat (-S -R) a v grafu se pak objeví jako dvojtečkovaná či tildová čára.
Výsledky si lze uložit do souboru (-w) a pak opět načíst (-o), ale nelze pak už změnit velikost bloku…
-w je dobré použít, uloží to údaje po každém testovaném soouboru a tedy i když se to pak zeštřelí, bo nás už nebaví na to čekat, tak něco z toho je.
(Pokud se to udělá kill <PID toho testu>, snad se to zestřelí až po skončení právě testovaného souboru - po všech vybraných kompresích.)

Tady je pár zbytečností či zajímavostí, ke ketrým jsme došel.

Výsledek z různých specifckých dat (80 adresářů/vzorků celkem do 15GiB), kde 20 % dole považuji za účelné (rcyhlost není důležitá, ale je hezky vidět jak je gzip rychlý):

Jinak na VMWare adresáře virtuálních strojů je 7z i 10 % efektivnější než bz2 či gz.

Když nic, tak jsem si opět připoměl, že minimálně za − (minus) pro bc je vhodné dávat mezeru, protože XY=-5; echo "10-${XY}" | bc to nesežere.

A fčul hurá na bramborový salát… (vyrobit, ne zlikvidovat…)

Jinak na VMWare adresáře virtuálních strojů je 7z i 10 % efektivnější než bz2 či gz.

Jestli si dobre pamatuju, tak je to tim ze 7z u kazdeho souboru testne jestli nejsou komprimovana data delsi nez nekomprimovana a pokud jo, tak ulozi do archivu ty nekomprimovana. Takze pokud je tam smeska ruznych typu souboru, muze to mit velmi pozitivni ucinek na vyslednou velikost.

Zaujímavé by bolo porovnať aj rzip, prípadne lrzip (a možno aj xz/lzip, ale tam budú asi výsledky o niečo horšie ako 7zip)

Jistě to podpoříš argumentem, a sice nejlépe odkazem na výjimku z pravidel českého pravopisu, která o takové grafické úpravě skloňování přejatých slov a jmen hovoří. Tvrdím, že taková úprava nejen neexistuje, ale navíc to vypadá nechutně.

Tyhle věci se nechávají bez skloňování. Stejně jako například číslovky psané číslicemi.

Souhlasím, možná je to správné, ale zato dementní (dle mého názoru) :-D. Kdo nehrotí normy a netrápí ho pohoršené pohledy puristů, nemá problém ;-). Ale napsal bych v bashi.
