Falls entweder \fB\-\fP oder keine Datei angegeben ist, +liest \fBxz\fP aus der Standardeingabe und leitet die verarbeiteten Dateien in +die Standardausgabe.

Sollte das Kopieren der Gruppe +fehlschlagen, werden die Zugriffsrechte so angepasst, dass jenen Benutzern +der Zugriff auf die Zieldatei verwehrt bleibt, die auch keinen Zugriff auf +die Ursprungs\-\fIDatei\fP hatten. Das Kopieren anderer Metadaten wie +Zugriffssteuerlisten oder erweiterter Attribute wird von \fBxz\fP noch nicht +unterstützt. +.PP +Sobald die Zieldatei erfolgreich geschlossen wurde, wird die +Ursprungs\-\fIDatei\fP entfernt. Dies wird durch die Option \fB\-\-keep\fP +verhindert. Die Ursprungs\-\fIDatei\fP wird niemals entfernt, wenn die Ausgabe +in die Standardausgabe geschrieben wird oder falls ein Fehler auftritt. +.PP +Durch Senden der Signale \fBSIGINFO\fP oder \fBSIGUSR1\fP an den \fBxz\fP\-Prozess +werden Fortschrittsinformationen in den Fehlerkanal der Standardausgabe +geleitet. Dies ist nur eingeschränkt hilfreich, wenn die +Standardfehlerausgabe ein Terminal ist. Mittels \fB\-\-verbose\fP wird ein +automatisch aktualisierter Fortschrittsanzeiger angezeigt. +. +.SS Speicherbedarf +In Abhängigkeit von den gewählten Kompressionseinstellungen bewegt sich der +Speicherverbrauch zwischen wenigen hundert Kilobyte und mehreren +Gigabyte. Die Einstellungen bei der Kompression einer Datei bestimmen dabei +den Speicherbedarf bei der Dekompression. Die Dekompression benötigt +üblicherweise zwischen 5\ % und 20\ % des Speichers, der bei der Kompression +der Datei erforderlich war. Beispielsweise benötigt die Dekompression einer +Datei, die mit \fBxz \-9\fP komprimiert wurde, gegenwärtig etwa 65\ MiB +Speicher. Es ist jedoch auch möglich, dass \fB.xz\fP\-Dateien mehrere Gigabyte +an Speicher zur Dekompression erfordern. +.PP +Insbesondere für Benutzer älterer Systeme wird eventuell ein sehr großer +Speicherbedarf ärgerlich sein. Um unangenehme Überraschungen zu vermeiden, +verfügt \fBxz\fP über eine eingebaute Begrenzung des Speicherbedarfs, die +allerdings in der Voreinstellung deaktiviert ist. Zwar verfügen einige +Betriebssysteme über eingebaute Möglichkeiten zur prozessabhängigen +Speicherbegrenzung, doch diese sind zu unflexibel (zum Beispiel kann +\fBulimit\fP(1) beim Begrenzen des virtuellen Speichers \fBmmap\fP(2) +beeinträchtigen). +.PP +Die Begrenzung des Speicherbedarfs kann mit der Befehlszeilenoption +\fB\-\-memlimit=\fP\fIBegrenzung\fP aktiviert werden. Oft ist es jedoch bequemer, +die Begrenzung durch Setzen der Umgebungsvariable \fBXZ_DEFAULTS\fP +standardmäßig zu aktivieren, zum Beispiel +\fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP. Die Begrenzungen können getrennt für +Kompression und Dekompression mittels \fB\-\-memlimit\-compress=\fP\fIBegrenzung\fP +und \fB\-\-memlimit\-decompress=\fP\fIBegrenzung\fP festgelegt werden. Die Verwendung +einer solchen Option außerhalb der Variable \fBXZ_DEFAULTS\fP ist kaum +sinnvoll, da \fBxz\fP in einer einzelnen Aktion nicht gleichzeitig Kompression +und Dekompression ausführen kann und \fB\-\-memlimit=\fP\fIBegrenzung\fP (oder \fB\-M\fP +\fIBegrenzung\fP) lässt sich einfacher in der Befehlszeile eingeben. +.PP +Wenn die angegebene Speicherbegrenzung bei der Dekompression überschritten +wird, schlägt der Vorgang fehl und \fBxz\fP zeigt eine Fehlermeldung an. Wird +die Begrenzung bei der Kompression überschritten, dann versucht \fBxz\fP die +Einstellungen entsprechend anzupassen, außer wenn \fB\-\-format=raw\fP oder +\fB\-\-no\-adjust\fP angegeben ist. Auf diese Weise schlägt die Aktion nicht fehl, +es sei denn, die Begrenzung wurde sehr niedrig angesetzt. Die Anpassung der +Einstellungen wird schrittweise vorgenommen, allerdings entsprechen die +Schritte nicht den Voreinstellungen der Kompressionsstufen. Das bedeutet, +wenn beispielsweise die Begrenzung nur geringfügig unter den Anforderungen +für \fBxz \-9\fP liegt, werden auch die Einstellungen nur wenig angepasst und +nicht vollständig herunter zu den Werten für \fBxz \-8\fP +. +.SS "Verkettung und Auffüllung von .xz\-Dateien" +Es ist möglich, \fB.xz\fP\-Dateien direkt zu verketten. Solche Dateien werden +von \fBxz\fP genauso dekomprimiert wie eine einzelne \fB.xz\fP\-Datei. +.PP +Es ist weiterhin möglich, eine Auffüllung zwischen den verketteten Teilen +oder nach dem letzten Teil einzufügen. Die Auffüllung muss aus Null\-Bytes +bestehen und deren Größe muss ein Vielfaches von vier Byte sein.

Die LZMA\-Utils tun das beim Komprimieren gewöhnlicher Dateien. Als +Alternative kann die unkomprimierte Größe als unbekannt markiert und eine +Nutzdatenende\-Markierung (end\-of\-payload) verwendet werden, um anzugeben, wo +der Dekompressor stoppen soll. Die LZMA\-Utils verwenden diese Methode, wenn +die unkomprimierte Größe unbekannt ist, was beispielsweise in Pipes +(Befehlsverkettungen) der Fall ist. +.PP +\fBxz\fP unterstützt die Dekompression von \fB.lzma\fP\-Dateien mit oder ohne +Nutzdatenende\-Markierung, aber alle von \fBxz\fP erstellten \fB.lzma\fP\-Dateien +verwenden diesen Nutzdatenende\-Markierung, wobei die unkomprimierte Größe in +den \fB.lzma\fP\-Headern als unbekannt markiert wird. Das könnte in einigen +unüblichen Situationen ein Problem sein. Zum Beispiel könnte ein +\&\fB.lzma\fP\-Dekompressor in einem Gerät mit eingebettetem System nur mit +Dateien funktionieren, deren unkomprimierte Größe bekannt ist. Falls Sie auf +dieses Problem stoßen, müssen Sie die LZMA\-Utils oder das LZMA\-SDK +verwenden, um \fB.lzma\fP\-Dateien mit bekannter unkomprimierter Größe zu +erzeugen. +. +.SS "Nicht unterstützte .lzma\-Dateien" +Das \fB.lzma\fP\-Format erlaubt \fIlc\fP\-Werte bis zu 8 und \fIlp\fP\-Werte bis zu +4. Die LZMA\-Utils können Dateien mit beliebigem \fIlc\fP und \fIlp\fP +dekomprimieren, aber erzeugen immer Dateien mit \fBlc=3\fP und \fBlp=0\fP. Das +Erzeugen von Dateien mit anderem \fIlc\fP und \fIlp\fP ist mit \fBxz\fP und mit dem +LZMA\-SDK möglich. +.PP +Die Implementation des LZMA\-Filters in liblzma setzt voraus, dass die Summe +von \fIlc\fP und \fIlp\fP nicht größer als 4 ist. Daher können \fB.lzma\fP\-Dateien, +welche diese Begrenzung überschreiten, mit \fBxz\fP nicht dekomprimiert werden. +.PP +Die LZMA\-Utils erzeugen nur \fB.lzma\fP\-Dateien mit einer Wörterbuchgröße von +2^\fIn\fP (einer Zweierpotenz), aber akzeptieren Dateien mit einer beliebigen +Wörterbuchgröße. Liblzma akzeptiert nur \fB.lzma\fP\-Dateien mit einer +Wörterbuchgröße von 2^\fIn\fP oder 2^\fIn\fP + 2^(\fIn\fP\-1). Dies dient zum +Verringern von Fehlalarmen beim Erkennen von \fB.lzma\fP\-Dateien. +.PP +Diese Einschränkungen sollten in der Praxis kein Problem sein, da praktisch +alle \fB.lzma\fP\-Dateien mit Einstellungen komprimiert wurden, die Liblzma +akzeptieren wird. +. +.SS "Angehängter Datenmüll" +Bei der Dekompression ignorieren die LZMA\-Utils stillschweigend alles nach +dem ersten \fB.lzma\fP\-Datenstrom. In den meisten Situationen ist das ein +Fehler. Das bedeutet auch, dass die LZMA\-Utils die Dekompression verketteter +\&\fB.lzma\fP\-Dateien nicht unterstützen. +.PP +Wenn nach dem ersten \fB.lzma\fP\-Datenstrom Daten verbleiben, erachtet \fBxz\fP +die Datei als beschädigt, es sei denn, die Option \fB\-\-single\-stream\fP wurde +verwendet. Dies könnte die Ausführung von Skripten beeinflussen, die davon +ausgehen, dass angehängter Datenmüll ignoriert wird. +. +.SH ANMERKUNGEN +. +.SS "Die komprimierte Ausgabe kann variieren" +Die exakte komprimierte Ausgabe, die aus der gleichen unkomprimierten +Eingabedatei erzeugt wird, kann zwischen den Versionen der XZ\-Utils +unterschiedlich sein, selbst wenn die Kompressionsoptionen identisch +sind. Das kommt daher, weil der Kodierer verbessert worden sein könnte +(hinsichtlich schnellerer oder besserer Kompression), ohne das Dateiformat +zu beeinflussen. Die Ausgabe kann sogar zwischen verschiedenen Programmen +der gleichen Version der XZ\-Utils variieren, wenn bei der Erstellung des +Binärprogramms unterschiedliche Optionen verwendet wurden. +.PP +Sobald \fB\-\-rsyncable\fP implementiert wurde, bedeutet das, dass die sich +ergebenden Dateien nicht notwendigerweise mit Rsync abgeglichen werden +können, außer wenn die alte und neue Datei mit der gleichen \fBxz\fP\-Version +erzeugt wurden.

Cela a un intérêt limité +car lorsque l'erreur standard est un terminal, utiliser \fB\-\-verbose\fP +affichera automatiquement un indicateur de progression du processus. +. +.SS "Utilisation de la mémoire" +L'utilisation de la mémoire par \fBxz\fP varie de quelques centaines de +kilo\-octets à plusieurs gigaoctects en fonction des paramètres de +compression. Les réglages utilisés lors de la compression d'un fichier +déterminent les besoins en mémoire pour la décompression. Habituellement la +décompression nécessite 5\% à 20\% de la quantité de mémoire utilisée pour +la compression du fichier. Par exemple, décompresser un fichier créé avec +\fBxz\-9\fP recquiert habituellement 65\ Mio de mémoire. Bien qu'il soit +possible d'avoir des fichiers \fB.xz\fP nécessitant plusieurs gigaoctets de +mémoire pour être décompressés. +.PP +Especially users of older systems may find the possibility of very large +memory usage annoying. To prevent uncomfortable surprises, \fBxz\fP has a +built\-in memory usage limiter, which is disabled by default. While some +operating systems provide ways to limit the memory usage of processes, +relying on it wasn't deemed to be flexible enough (for example, using +\fBulimit\fP(1) to limit virtual memory tends to cripple \fBmmap\fP(2)). +.PP +The memory usage limiter can be enabled with the command line option +\fB\-\-memlimit=\fP\fIlimit\fP. Often it is more convenient to enable the limiter +by default by setting the environment variable \fBXZ_DEFAULTS\fP, for example, +\fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP. It is possible to set the limits +separately for compression and decompression by using +\fB\-\-memlimit\-compress=\fP\fIlimit\fP and \fB\-\-memlimit\-decompress=\fP\fIlimit\fP. +Using these two options outside \fBXZ_DEFAULTS\fP is rarely useful because a +single run of \fBxz\fP cannot do both compression and decompression and +\fB\-\-memlimit=\fP\fIlimit\fP (or \fB\-M\fP \fIlimit\fP) is shorter to type on the +command line. +.PP +If the specified memory usage limit is exceeded when decompressing, \fBxz\fP +will display an error and decompressing the file will fail. If the limit is +exceeded when compressing, \fBxz\fP will try to scale the settings down so that +the limit is no longer exceeded (except when using \fB\-\-format=raw\fP or +\fB\-\-no\-adjust\fP). This way the operation won't fail unless the limit is very +small. The scaling of the settings is done in steps that don't match the +compression level presets, for example, if the limit is only slightly less +than the amount required for \fBxz \-9\fP, the settings will be scaled down only +a little, not all the way down to \fBxz \-8\fP. +. +.SS "Concaténation et remplissage avec des fichiers .xz" +Il est possible de concaténer les fichiers \fB.xz\fP tels quel. \fBxz\fP +décompressera de tels fichiers comme s'ils étaient un unique fichier \fB.xz\fP. +.PP +It is possible to insert padding between the concatenated parts or after the +last part.

The alternative is to +mark that uncompressed size is unknown and use end\-of\-payload marker to +indicate where the decompressor should stop. LZMA Utils uses this method +when uncompressed size isn't known, which is the case, for example, in +pipes. +.PP +\fBxz\fP prend en charge la décompression des fichiers \fB.lzma\fP avec ou sans +marqueur de fin de charge utile, mais tous les fichiers \fB.lzma\fP créés par +\fBxz\fP utiliseront un marqueur de fin de charge utile et ont la taille non +compréssée marquée comme inconnue dans l'en\-tête \fB.lzma\fP. Cela peut être un +problème dans quelques situations inhabituelles. Par exemple, un +décompresseur \fB.lzma\fP dans un périphérique embarqué pourrait ne fonctionner +qu'avec des fichiers dont la taille non comprimée est connue. Si vous vous +heurtez à ce problème, vous devez utiliser les utilitaires LZMA ou LZMA SDK +pour créer des fichiers \fB.lzma\fP avec une taille non compressée connue. +. +.SS "Fichiers .lzma non pris en charge" +Le format \fB.lzma\fP autorise des valeurs \fIlc\fP jusqu'à\ 8, et des valeurs +\fIlp\fP jusqu'à\ 4. Les outils LZMA peuvent décompresser des fichiers avec tous +les \fIlc\fP et \fIlp\fP, mais créez toujours les fichiers avec \fBlc=3\fP et +\fBlp=0\fP. Créer des fichiers avec d'autres valeurs \fIlc\fP et \fIlp\fP est +possible avec \fBxz\fP et avec LZMA SDK. +.PP +L'implémentation du filtre LZMA1 dans liblzma nécessite que la somme de +\fIlc\fP et \fIlp\fP soit inférieure ou égale à\ 4. Ainsi, les fichiers \fB.lzma\fP +qui excèdent cette limitation ne peuvent pas être décompressés avec \fBxz\fP. +.PP +Les outils LZMA créent seulement des fichiers \fB.lzma\fP qui ont une taille de +dictionnaire de 2^\fIn\fP (une puissance de\ 2) mais acceptent les fichiers avec +toutes les tailles de dictionnaire. Libzlma n'accepte que les fichiers +\&\fB.lzma\fP qui ont une taille dictionnaire de 2^\fIn\fP ou +2^\fIn\fP\ +\ 2^(\fIn\fP\-1). Cela afin de diminuer les faux positifs lors de la +détection des fichiers \fB.lzma\fP. +.PP +Ces limitations ne devraient pas poser problème en pratique, car +pratiquement tous les fichiers \fB.lzma\fP ont été compressés avec des réglages +que liblzma accepte. +. +.SS "Déchets excédentaires" +Lors de la décompession, l'utilitaire LZMA ignore silencieusement tout ce +qui est après le premier flux \fB.lzma\fP. Dans la majorité des situations, +c'est un bogue. Cela veut dire aussi que les outils LZMA ne gèrent pas la +décompression de fichiers \fB.lzma\fP concaténés. +.PP +S'il reste des données après le premier flux \fB.lzma\fP, \fBxz\fP considère que +le fichier est corrompu sauf si \fB\-\-single\-stream\fP a été utilisé.

때, 압축 프로그램 메모리 사용량의 +5% 에서 20% 정도 필요합니다. 예를 들면, \fBxz \-9\fP로 압축한 파일 압축 해제시 현재 65MiB 메모리 용량이 필요합니다. +여전하게도, 압축 해제시 수 기가 바이트의 메모리가 필요한 \fB.xz\fP 파일에도 가능한 이야기입니다. +.PP +특히 이전 시스템 사용자의 경우 메모리 사용량이 엄청나게 늘어나는 점에 짜증이 날 수 있습니다. 이런 불편한 상황을 피하기 위해, +\fBxz\fP에 기본적으로 비활성 상태인 내장 메모리 사용 제한 기능을 넣었습니다. 일부 운영체제에서 처리 중 메모리 사용을 제한하는 +수단을 제공하긴 하지만, 여기에 의지하기에는 충분히 유연하지 않습니다(예를 들면, \fBulimit\fP(1)을 사용하면 가상 메모리를 +제한하여 \fBmmap\fP(2)을 먹통으로 만듭니다). +.PP +메모리 사용 제한 기능은 \fB\-\-memlimit=\fP\fI<제한용량>\fP 명령행 옵션으로 사용할 수 있습니다. 종종 +\fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP와 같이 \fBXZ_DEFAULTS\fP 환경 변수를 설정하여 제한 기능을 켜는게 더 +편합니다. \fB\-\-memlimit\-compress=\fP\fI<제한용량>\fP 옵션과 +\fB\-\-memlimit\-decompress=\fP\fI<제한용량>\fP 옵션을 활용하여 압축 및 압축 해제시 별도로 한계 값을 +설정할 수 있습니다. 이 두 가지 옵션의 \fBXZ_DEFAULTS\fP 환경 변수 밖에서의 사용은, \fBxz\fP를 단일 실행할 때 압축 및 +압축 해제 동작을 동시에 수행하지 않으며, 앞서 언급한 두가지 옵션을 명령행에 입력하기에는 +\fB\-\-memlimit=\fP\fI<제한용량>\fP(또는 \fB\-M\fP \fI<제한용량>\fP)이 더 짧기 때문에 별로 쓸모가 +없습니다. +.PP +압축 해제시 메모리 사용 제한 지정 한계를 초과하면, \fBxz\fP 유틸리티에서 오류를 나타내며 파일 압축 해제는 실패합니다. 압축을 +실행할 때 사용 제한 지정 한계를 넘어서면 \fBxz\fP에서는 설정 값을 줄여서 어쨌든 한계를 넘지 못하게 +합니다(\fB\-\-format=raw\fP 옵션 또는 \fB\-\-no\-adjust\fP 옵션 사용시 제외). 설정 한계 값이 엄청 작지 않은 이상 이 +방식대로 처리하면 어쨌든 실패하지 않습니다. 설정 값조정은 압축 래벨 사전 설정과 일치하지 않을 때 단계적으로 진행하는데, 이를테면, +\fBxz \-9\fP 명령 수행에 필요한 양보다 한계 값이 약간 작으면, 설정 값을 \fBxz \-8\fP에 못미치게 약간 줄여서 진행합니다. +. +.SS ".xz 파일 결합 및 패딩" +\&\fB.xz\fP 파일을 있는 그대로 합칠 수 있습니다.

Isso tem uso limitado, +pois quando o erro padrão é um terminal, usar \fB\-\-verbose\fP exibirá um +indicador de progresso de atualização automática. +. +.SS "Uso de memória" +O uso de memória de \fBxz\fP varia de algumas centenas de kilobytes a vários +gigabytes, dependendo das configurações de compactação. As configurações +usadas ao compactar um arquivo determinam os requisitos de memória do +descompactador. Normalmente, o descompactador precisa de 5\ % a 20\ % da +quantidade de memória que o compactador precisou ao criar o arquivo. Por +exemplo, descompactar um arquivo criado com \fBxz \-9\fP atualmente requer 65\ MiB de memória. Ainda assim, é possível ter arquivos \fB.xz\fP que requerem +vários gigabytes de memória para descompactar. +.PP +Especialmente os usuários de sistemas mais antigos podem achar irritante a +possibilidade de uso de memória muito grande. Para evitar surpresas +desconfortáveis, o \fBxz\fP possui um limitador de uso de memória embutido, que +está desabilitado por padrão. Embora alguns sistemas operacionais forneçam +maneiras de limitar o uso de memória dos processos, confiar nele não foi +considerado flexível o suficiente (por exemplo, usar \fBulimit\fP(1) para +limitar a memória virtual tende a prejudicar \fBmmap\fP(2)). +.PP +O limitador de uso de memória pode ser ativado com a opção de linha de +comando \fB\-\-memlimit=\fP\fIlimite\fP. Geralmente é mais conveniente habilitar o +limitador por padrão definindo a variável de ambiente \fBXZ_DEFAULTS\fP, por +exemplo, \fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP. É possível definir os limites +separadamente para compactação e descompactação usando +\fB\-\-memlimit\-compress=\fP\fIlimite\fP e \fB\-\-memlimit\-decompress=\fP\fIlimite\fP. Usar +essas duas opções fora de \fBXZ_DEFAULTS\fP raramente é útil porque uma única +execução de \fBxz\fP não pode fazer compactação e descompactação e +\fB\-\-memlimit=\fP\fIlimite\fP (ou \fB\-M\fP \fIlimite\fP ) é mais curto para digitar na +linha de comando. +.PP +Se o limite de uso de memória especificado for excedido durante a +descompactação, \fBxz\fP exibirá um erro e a descompactação do arquivo +falhará. Se o limite for excedido durante a compactação, \fBxz\fP tentará +reduzir as configurações para que o limite não seja mais excedido (exceto ao +usar \fB\-\-format=raw\fP ou \fB\-\-no\-adjust\fP). Dessa forma, a operação não +falhará, a menos que o limite seja muito pequeno. A escala das configurações +é feita em etapas que não correspondem às predefinições do nível de +compactação, por exemplo, se o limite for apenas um pouco menor que o valor +necessário para \fBxz \-9\fP, as configurações serão reduzidas apenas um pouco , +não até \fBxz \-8\fP. +. +.SS "Concatenação e preenchimento com arquivos .xz" +É possível concatenar arquivos \fB.xz\fP como estão. \fBxz\fP irá descompactar +tais arquivos como se fossem um único arquivo \fB.xz\fP. +.PP +É possível inserir preenchimento entre as partes concatenadas ou após a +última parte. O preenchimento deve consistir em bytes nulos e o tamanho do +preenchimento deve ser um múltiplo de quatro bytes.

Isso é para diminuir +os falsos positivos ao detectar arquivos \fB.lzma\fP. +.PP +Essas limitações não devem ser um problema na prática, já que praticamente +todos os arquivos \fB.lzma\fP foram compactados com configurações que o liblzma +aceitará. +. +.SS "Lixo à direita" +Ao descompactar, o LZMA Utils silenciosamente ignora tudo após o primeiro +fluxo \fB.lzma\fP. Na maioria das situações, isso é um bug. Isso também +significa que o LZMA Utils não oferece suporte a descompactação de arquivos +\&\fB.lzma\fP concatenados. +.PP +Se houver dados restantes após o primeiro fluxo de \fB.lzma\fP, \fBxz\fP considera +o arquivo corrompido, a menos que \fB\-\-single\-stream\fP tenha sido usado.

A saída pode variar mesmo entre diferentes compilações da mesma +versão do XZ Utils, se diferentes opções de compilação forem usadas. +.PP +A informação acima significa que, uma vez que \fB\-\-rsyncable\fP tenha sido +implementado, os arquivos resultantes não serão necessariamente +"rsyncáveis", a menos que os arquivos antigos e novos tenham sido +compactados com a mesma versão xz.

De obicei, instrumentul de +decomprimare are nevoie de 5% până la 20% din cantitatea de memorie de care +a avut nevoie instrumentul de comprimare la crearea fișierului. De exemplu, +decomprimarea unui fișier creat cu \fBxz \-9\fP necesită în prezent 65Mio de +memorie. Totuși, este posibil să aveți fișiere \fB.xz\fP care necesită câțiva +gigaocteți de memorie pentru decomprimare. +.PP +În special utilizatorii de sisteme mai vechi pot considera deranjantă +posibilitatea unei utilizări foarte mari a memoriei. Pentru a preveni +surprizele neplăcute, \fBxz\fP are încorporat un limitator de utilizare a +memoriei, care este dezactivat implicit. În timp ce unele sisteme de +operare oferă modalități de a limita utilizarea memoriei proceselor, bazarea +pe aceasta nu a fost considerată a fi suficient de flexibilă (de exemplu, +utilizarea \fBulimit\fP(1) pentru a limita memoria virtuală tinde să paralizeze +\fBmmap\fP(2)). +.PP +Limitatorul de utilizare a memoriei poate fi activat cu opțiunea din linia +de comandă \fB\-\-memlimit=\fP\fIlimita\fP. Adesea este mai convenabil să activați +limitatorul în mod implicit prin definirea variabilei de mediu +\fBXZ_DEFAULTS\fP, de exemplu, \fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP. Este posibil +să stabiliți limitele separat pentru comprimare și decomprimare folosind +\fB\-\-memlimit\-compress=\fP\fIlimita\fP și \fB\-\-memlimit\-decompress=\fP\fIlimita\fP. +Utilizarea acestor două opțiuni în afara \fBXZ_DEFAULTS\fP este foarte rar +utilă, deoarece o singură rulare a \fBxz\fP nu poate face atât comprimarea, cât +și decomprimarea și \fB\-\-memlimit=\fP\fIlimita\fP (sau \fB\-M\fP \fIlimita\fP ) este mai +scurt de tastat pe linia de comandă. +.PP +Dacă limita de utilizare a memoriei specificată este depășită la +decomprimare, \fBxz\fP va afișa o eroare și decomprimarea fișierului va eșua. +Dacă limita este depășită la comprimare, \fBxz\fP va încerca să reducă valorile +stabilite astfel încât limita să nu mai fie depășită (cu excepția cazului în +care se utilizează opțiunea \fB\-\-format=raw\fP sau \fB\-\-no\-adjust\fP). În acest +fel, operațiunea nu va eșua decât dacă limita stabilită este foarte mică. +Scalarea valorilor stabilite se face în pași care nu se potrivesc cu +valorile prestabilite ale nivelului de comprimare, de exemplu, dacă limita +este doar puțin mai mică decât cantitatea necesară pentru \fBxz \-9\fP, valorile +stabilite vor fi reduse doar puțin , nu până la valoarea prestabilită a lui +\fBxz \-8\fP. +. +.SS "Concatenare și completare (prin umplere cu octeți nuli) cu fișiere .xz" +Este posibil să concatenați fișierele \fB.xz\fP așa cum sunt. \fBxz\fP va +decomprima astfel de fișiere ca și cum ar fi un singur fișier \fB.xz\fP. +.PP +Este posibil să se introducă umplutură între părțile concatenate sau după +ultima parte.

Alternativa +este să marcați că dimensiunea necomprimată este necunoscută și să folosiți +marcajul de sfârșit de încărcare pentru a indica unde ar trebui să se +oprească decomprimarea. LZMA Utils folosește această metodă atunci când +dimensiunea necomprimată nu este cunoscută, ceea ce este cazul, de exemplu, +când se folosesc conducte. +.PP +\fBxz\fP acceptă decomprimarea fișierelor \fB.lzma\fP cu sau fără marcaj de +sfârșit de încărcare, dar toate fișierele \fB.lzma\fP create de \fBxz\fP vor +folosi marcajul de sfârșit de încărcare și vor avea dimensiunea necomprimată +marcată ca necunoscută în antetul \fB.lzma\fP. Aceasta poate fi o problemă în +unele situații mai puțin frecvente. De exemplu, un instrument de +decomprimare \fB.lzma\fP încorporat într\-un dispozitiv poate funcționa numai cu +fișiere care au dimensiunea necomprimată cunoscută. Dacă întâmpinați +această problemă, trebuie să utilizați LZMA Utils sau LZMA SDK pentru a crea +fișiere \fB.lzma\fP cu dimensiunea necomprimată cunoscută. +. +.SS "Fișiere .lzma neacceptate" +Formatul \fB.lzma\fP permite valori \fIlc\fP de până la 8 și valori \fIlp\fP de până +la 4. LZMA Utils poate decomprima fișiere cu orice \fIlc\fP și \fIlp\fP, dar +creează întotdeauna fișiere cu \fBlc=3\fP și \fBlp=0\fP. Crearea de fișiere cu +alte \fIlc\fP și \fIlp\fP este posibilă cu \fBxz\fP și cu LZMA SDK. +.PP +Implementarea filtrului LZMA1 în liblzma necesită ca suma \fIlc\fP și \fIlp\fP să +nu depășească 4. Altfel, fișierele \fB.lzma\fP, care depășesc această +limitare, nu pot fi decomprimate cu \fBxz\fP. +.PP +LZMA Utils creează numai fișiere \fB.lzma\fP care au o dimensiune de dicționar +de 2^\fIn\fP (o putere de 2), dar acceptă fișiere cu orice dimensiune de +dicționar. liblzma acceptă numai fișierele \fB.lzma\fP care au dimensiunea de +dicționar de 2^\fIn\fP sau 2^\fIn\fP + 2^(\fIn\fP\-1). Acest lucru este pentru a +reduce numărul de „fals pozitiv” atunci când se detectează fișiere \fB.lzma\fP. +.PP +Aceste limitări nu ar trebui să fie o problemă în practică, deoarece practic +toate fișierele \fB.lzma\fP au fost comprimate cu opțiuni pe care liblzma le va +accepta. +. +.SS "Resturi rămase" +Când decomprimă, LZMA Utils ignoră în tăcere totul după primul flux +\&\fB.lzma\fP. În majoritatea situațiilor, aceasta este o eroare. Aceasta +înseamnă, de asemenea, că LZMA Utils nu acceptă decomprimarea fișierelor +\&\fB.lzma\fP concatenate. +.PP +Dacă au rămas date după primul flux \fB.lzma\fP, \fBxz\fP consideră că fișierul +este corupt, cu excepția cazului în care a fost utilizată opțiunea +\fB\-\-single\-stream\fP. Acest lucru poate rupe scripturile obscure(scrise +deficitar) care presupun că resturile rămase sunt ignorate. +. +.SH NOTE +. +.SS "Rezultatul comprimării poate varia" +Ieșirea exactă comprimată produsă din același fișier de intrare necomprimat +poate varia între versiunile XZ Utils, chiar dacă opțiunile de comprimare +sunt identice. Acest lucru se datorează faptului că instrumentul +codificator poate fi îmbunătățit (comprimare mai rapidă sau mai bună) fără a +afecta formatul fișierului. Ieșirea poate varia chiar și între compilările +diferite ale aceleiași versiuni XZ Utils, dacă sunt utilizate opțiuni +diferite de compilare. +.PP +Cele de mai sus înseamnă că odată ce opțiunea \fB\-\-rsyncable\fP a fost +utilizată, fișierele rezultate nu vor fi neapărat sincronizate cu rsync +decât dacă atât fișierele vechi, cât și cele noi au fost comprimate cu +aceeași versiune xz. Această problemă poate fi remediată dacă o parte a +implementării codificatorului este înghețată pentru a menține stabilă +ieșirea „rsyncabilă” între versiunile xz. +. +.SS "Instrumente de decomprimare .xz încorporate" +Implementările instrumentului de decomprimare \fB.xz\fP încorporat, cum ar fi +XZ Embedded, nu acceptă neapărat fișiere create cu tipuri de \fIverificare\fP a +integrității, altele decât \fBnone\fP și \fBcrc32\fP.

Параметри, які +використано при стисканні файла, визначають вимоги до об'єму пам'яті при +розпакуванні.

Наприклад, розпаковування файла, який створено з використанням \fBxz \-9\fP, у поточній версії потребує 65\ МіБ пам'яті. Втім, можливе створення +файлів \fB.xz\fP, які потребуватимуть для розпаковування декількох гігабайтів +пам'яті. +.PP +Ймовірність високого рівня використання пам'яті може бути особливо +дошкульною для користувачів застарілих комп'ютерів. Щоб запобігти прикрим +несподіванкам, у \fBxz\fP передбачено вбудований обмежувач пам'яті, який типово +вимкнено. Хоча у деяких операційних системах передбачено спосіб обмежити +використання пам'яті процесами, сподівання на його ефективність не є аж +надто гнучким (наприклад, використання \fBulimit\fP(1) для обмеження +віртуальної пам'яті призводить до викривлення даних \fBmmap\fP(2)). +.PP +Обмежувач пам'яті можна увімкнути за допомогою параметра командного рядка +\fB\-\-memlimit=\fP\fIобмеження\fP. Часто, зручніше увімкнути обмежувач на типовому +рівні, встановивши значення для змінної середовища \fBXZ_DEFAULTS\fP, +наприклад, \fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP. Можна встановити обмеження +окремо для стискання і розпакування за допомогою +\fB\-\-memlimit\-compress=\fP\fIlimit\fP and +\fB\-\-memlimit\-decompress=\fP\fIобмеження\fP. Використання цих двох параметрів поза +\fBXZ_DEFAULTS\fP не таке вже і корисне, оскільки одноразовий запуск \fBxz\fP не +може одночасно призводити до стискання та розпаковування, а набрати у +командному рядку \fB\-\-memlimit=\fP\fIобмеження\fP (або \fB\-M\fP \fIобмеження\fP) +набагато швидше. +.PP +Якщо під час розпаковування вказане обмеження буде перевищено, \fBxz\fP покаже +повідомлення про помилку, а розпаковування файла зазнає невдачі. Якщо +обмеження буде перевищено при стисканні, \fBxz\fP спробує масштабувати +параметри так, щоб не перевищувати обмеження (окрім випадків використання +\fB\-\-format=raw\fP або \fB\-\-no\-adjust\fP). Отже, дію буде виконано, якщо обмеження +не є надто жорстким. Масштабування параметрів буде виконано кроками, які не +збігаються із рівнями шаблонів стискання. Наприклад, якщо обмеження лише +трохи не вкладається у об'єм потрібний для \fBxz \-9\fP, параметри буде змінено +лише трохи, не до рівня \fBxz \-8\fP. +. +.SS "Поєднання і заповнення з файлами .xz" +Можна поєднати файли \fB.xz\fP без додаткової обробки. \fBxz\fP розпакує такі +файли так, наче вони є єдиним файлом \fB.xz\fP. +.PP +Можна додати доповнення між з'єднаними частинами або після останньої +частини.
