IPhoto library cannot be found. How to get it back. 2009 2:42 AM PDT. Users may experience an issue with iPhoto in which the library will not load, and the application shows an empty window. Apr 01, 2020 Designate a System Photo Library in Photos If you have multiple photo libraries on your Mac, you can choose one to be the System Photo Library. The System Photo Library is the only library that can be used with iCloud Photos, Shared Albums, and My Photo Stream. Mar 11, 2019 Apache HTTP Installation Troubleshooting Guide. Expat.h: No such file or directory. C compiler not found is typical for any software build, and you can fix. Nov 09, 2012  How to Reveal Your Library Folder in Lion or Mountain Lion. By Johnny Winter 9 Nov 2012. Difficulty: Intermediate. Folder at the root level of your hard drive is a public ‘library’ of data that is required for all users of the Mac. The Library folder within the System folder is critical for the operation of your Mac. Don’t ever remove. Ever since Lion (OS X 10.7), Apple has hidden your personal Library folder (/Library) by default. In Lion and Mountain Lion (OS X 10.8), you could make the folder visible, but it required some work.

Photos in your System Photo Library are available in apps like iMovie, Pages, and Keynote. You can also sync them to iOS devices and view them on Apple TV. And if you want to use your own images as your desktop picture or screen saver, the images need to be in your System Photo Library before you can select them in System Preferences.

If you have only one photo library, then it's the System Photo Library. Otherwise, the first photo library that you create or open in Photos will become the System Photo Library. If you have more than one library, you might need to designate a System Photo Library, so other apps can access the photos and videos you want them to use.

Follow these steps to designate a System Photo Library:

1. Quit Photos.
2. Hold down the Option key and open Photos. One of the photo libraries is already designated as YourLibraryName (System Photo Library).
3. Choose the library you want to designate as the System Photo Library.
4. After Photos opens the library, choose Photos > Preferences from the menu bar.
5. Click the General tab.
6. Click the Use as System Photo Library button.
   

If you open a second or different library in the Photos app, and you haven't designated it as the System Photo Library, other applications will use photos from the original System Photo Library. Hold down the Option key when you open Photos to see which library is set as the System Photo Library.

iCloud and the System Photo Library

You can use iCloud Photos, Shared Albums, and My Photo Stream only with the System Photo Library. If you choose a different library in Photos without designating it as the System Photo Library, the iCloud tab in Photos preferences is disabled:

If you designate a new library as the System Photo Library and then turn on iCloud Photos, the photos and videos in the new library will merge with those already in your iCloud Photos. If you want to keep the contents of your photo libraries separate, don’t turn on iCloud Photos for more than one library in Photos.

Warning

The pyexpat module is not secure against maliciouslyconstructed data. If you need to parse untrusted or unauthenticated data seeXML vulnerabilities.

The xml.parsers.expat module is a Python interface to the Expatnon-validating XML parser. The module provides a single extension type,xmlparser, that represents the current state of an XML parser. Afteran xmlparser object has been created, various attributes of the objectcan be set to handler functions. When an XML document is then fed to theparser, the handler functions are called for the character data and markup inthe XML document.

This module uses the pyexpat module to provide access to the Expatparser. Direct use of the pyexpat module is deprecated.

This module provides one exception and one type object:

The exception raised when Expat reports an error. See sectionExpatError Exceptions for more information on interpreting Expat errors.

Alias for ExpatError.

The type of the return values from the ParserCreate() function.

The xml.parsers.expat module contains two functions:

Returns an explanatory string for a given error number errno.

Creates and returns a new xmlparser object. encoding, if specified,must be a string naming the encoding used by the XML data. Expat doesn’tsupport as many encodings as Python does, and its repertoire of encodings can’tbe extended; it supports UTF-8, UTF-16, ISO-8859-1 (Latin1), and ASCII. Ifencoding1 is given it will override the implicit or explicit encoding of thedocument.

Expat can optionally do XML namespace processing for you, enabled by providing avalue for namespace_separator. The value must be a one-character string; aValueError will be raised if the string has an illegal length (Noneis considered the same as omission). When namespace processing is enabled,element type names and attribute names that belong to a namespace will beexpanded. The element name passed to the element handlersStartElementHandler and EndElementHandler will be theconcatenation of the namespace URI, the namespace separator character, and thelocal part of the name. If the namespace separator is a zero byte (chr(0))then the namespace URI and the local part will be concatenated without anyseparator.

For example, if namespace_separator is set to a space character ('') andthe following document is parsed:

StartElementHandler will receive the following strings for eachelement:

Due to limitations in the Expat library used by pyexpat,the xmlparser instance returned can only be used to parse a singleXML document. Call ParserCreate for each document to provide uniqueparser instances.

19.15.1. XMLParser Objects¶

xmlparser objects have the following methods:

Parses the contents of the string data, calling the appropriate handlerfunctions to process the parsed data. isfinal must be true on the final callto this method; it allows the parsing of a single file in fragments,not the submission of multiple files.data can be the empty string at any time.

Parse XML data reading from the object file. file only needs to providethe read(nbytes) method, returning the empty string when there’s no moredata.

Sets the base to be used for resolving relative URIs in system identifiers indeclarations. Resolving relative identifiers is left to the application: thisvalue will be passed through as the base argument to theExternalEntityRefHandler(), NotationDeclHandler(), andUnparsedEntityDeclHandler() functions.

Returns a string containing the base set by a previous call to SetBase(),or None if SetBase() hasn’t been called.

Returns the input data that generated the current event as a string. The data isin the encoding of the entity which contains the text. When called while anevent handler is not active, the return value is None.

Create a “child” parser which can be used to parse an external parsed entityreferred to by content parsed by the parent parser. The context parametershould be the string passed to the ExternalEntityRefHandler() handlerfunction, described below. The child parser is created with theordered_attributes, returns_unicode andspecified_attributes set to the values of this parser.

Control parsing of parameter entities (including the external DTD subset).Possible flag values are XML_PARAM_ENTITY_PARSING_NEVER,XML_PARAM_ENTITY_PARSING_UNLESS_STANDALONE andXML_PARAM_ENTITY_PARSING_ALWAYS. Return true if setting the flagwas successful.

Calling this with a true value for flag (the default) will cause Expat to callthe ExternalEntityRefHandler with None for all arguments toallow an alternate DTD to be loaded. If the document does not contain adocument type declaration, the ExternalEntityRefHandler will still becalled, but the StartDoctypeDeclHandler andEndDoctypeDeclHandler will not be called.

Passing a false value for flag will cancel a previous call that passed a truevalue, but otherwise has no effect.

This method can only be called before the Parse() or ParseFile()methods are called; calling it after either of those have been called causesExpatError to be raised with the code attribute set toerrors.XML_ERROR_CANT_CHANGE_FEATURE_ONCE_PARSING.

New in version 2.3.How to install library in python mac os.

xmlparser objects have the following attributes:

The size of the buffer used when buffer_text is true.A new buffer size can be set by assigning a new integer valueto this attribute.When the size is changed, the buffer will be flushed.

Changed in version 2.6: The buffer size can now be changed.

Setting this to true causes the xmlparser object to buffer textualcontent returned by Expat to avoid multiple calls to theCharacterDataHandler() callback whenever possible. This can improveperformance substantially since Expat normally breaks character data into chunksat every line ending. This attribute is false by default, and may be changed atany time.

If buffer_text is enabled, the number of bytes stored in the buffer.These bytes represent UTF-8 encoded text. This attribute has no meaningfulinterpretation when buffer_text is false.

New in version 2.3.

Setting this attribute to a non-zero integer causes the attributes to bereported as a list rather than a dictionary. The attributes are presented inthe order found in the document text. For each attribute, two list entries arepresented: the attribute name and the attribute value. (Older versions of thismodule also used this format.) By default, this attribute is false; it may bechanged at any time.

If this attribute is set to a non-zero integer, the handler functions will bepassed Unicode strings. If returns_unicode is False, 8-bitstrings containing UTF-8 encoded data will be passed to the handlers. This isTrue by default when Python is built with Unicode support.

Changed in version 1.6: Can be changed at any time to affect the result type.

If set to a non-zero integer, the parser will report only those attributes whichwere specified in the document instance and not those which were derived fromattribute declarations. Applications which set this need to be especiallycareful to use what additional information is available from the declarations asneeded to comply with the standards for the behavior of XML processors. Bydefault, this attribute is false; it may be changed at any time.

The following attributes contain values relating to the most recent errorencountered by an xmlparser object, and will only have correct valuesonce a call to Parse() or ParseFile() has raised anxml.parsers.expat.ExpatError exception.

Byte index at which an error occurred.

Numeric code specifying the problem. This value can be passed to theErrorString() function, or compared to one of the constants defined in theerrors object.

Column number at which an error occurred.

Line number at which an error occurred.

The following attributes contain values relating to the current parse locationin an xmlparser object. During a callback reporting a parse event theyindicate the location of the first of the sequence of characters that generatedthe event. When called outside of a callback, the position indicated will bejust past the last parse event (regardless of whether there was an associatedcallback).

New in version 2.4.

Current byte index in the parser input.

Current column number in the parser input.

Current line number in the parser input.

Here is the list of handlers that can be set. To set a handler on anxmlparser object o, use o.handlername=func. handlername mustbe taken from the following list, and func must be a callable object acceptingthe correct number of arguments. The arguments are all strings, unlessotherwise stated.

Called when the XML declaration is parsed. The XML declaration is the(optional) declaration of the applicable version of the XML recommendation, theencoding of the document text, and an optional “standalone” declaration.version and encoding will be strings of the type dictated by thereturns_unicode attribute, and standalone will be 1 if thedocument is declared standalone, 0 if it is declared not to be standalone,or -1 if the standalone clause was omitted. This is only available withExpat version 1.95.0 or newer.

Called when Expat begins parsing the document type declaration (<!DOCTYPE..). The doctypeName is provided exactly as presented. The systemId andpublicId parameters give the system and public identifiers if specified, orNone if omitted. has_internal_subset will be true if the documentcontains and internal document declaration subset. This requires Expat version1.2 or newer.

Called when Expat is done parsing the document type declaration. This requiresExpat version 1.2 or newer.

Called once for each element type declaration. name is the name of theelement type, and model is a representation of the content model.

Called for each declared attribute for an element type. If an attribute listdeclaration declares three attributes, this handler is called three times, oncefor each attribute. elname is the name of the element to which thedeclaration applies and attname is the name of the attribute declared. Theattribute type is a string passed as type; the possible values are'CDATA', 'ID', 'IDREF', … default gives the default value forthe attribute used when the attribute is not specified by the document instance,or None if there is no default value (#IMPLIED values). If theattribute is required to be given in the document instance, required will betrue. This requires Expat version 1.95.0 or newer.

Called for the start of every element. name is a string containing theelement name, and attributes is a dictionary mapping attribute names to theirvalues.

Called for the end of every element.

Called for every processing instruction.

Called for character data. This will be called for normal character data, CDATAmarked content, and ignorable whitespace. Applications which must distinguishthese cases can use the StartCdataSectionHandler,EndCdataSectionHandler, and ElementDeclHandler callbacks tocollect the required information.

Called for unparsed (NDATA) entity declarations. This is only present forversion 1.2 of the Expat library; for more recent versions, useEntityDeclHandler instead. (The underlying function in the Expatlibrary has been declared obsolete.)

Called for all entity declarations. For parameter and internal entities,value will be a string giving the declared contents of the entity; this willbe None for external entities. The notationName parameter will beNone for parsed entities, and the name of the notation for unparsedentities. is_parameter_entity will be true if the entity is a parameter entityor false for general entities (most applications only need to be concerned withgeneral entities). This is only available starting with version 1.95.0 of theExpat library.

New in version 2.1.

Called for notation declarations. notationName, base, and systemId, andpublicId are strings if given. If the public identifier is omitted,publicId will be None.

Called when an element contains a namespace declaration. Namespace declarationsare processed before the StartElementHandler is called for the elementon which declarations are placed.

Called when the closing tag is reached for an element that contained anamespace declaration. This is called once for each namespace declaration onthe element in the reverse of the order for which theStartNamespaceDeclHandler was called to indicate the start of eachnamespace declaration’s scope. Calls to this handler are made after thecorresponding EndElementHandler for the end of the element.

Called for comments. data is the text of the comment, excluding the leading'<!--' and trailing '-->'.

Called at the start of a CDATA section. This and EndCdataSectionHandlerare needed to be able to identify the syntactical start and end for CDATAsections.

Called at the end of a CDATA section.

Called for any characters in the XML document for which no applicable handlerhas been specified. This means characters that are part of a construct whichcould be reported, but for which no handler has been supplied.

This is the same as the DefaultHandler(), but doesn’t inhibit expansionof internal entities. The entity reference will not be passed to the defaulthandler.

Called if the XML document hasn’t been declared as being a standalone document.This happens when there is an external subset or a reference to a parameterentity, but the XML declaration does not set standalone to yes in an XMLdeclaration. If this handler returns 0, then the parser will raise anXML_ERROR_NOT_STANDALONE error. If this handler is not set, noexception is raised by the parser for this condition.

Called for references to external entities. base is the current base, as setby a previous call to SetBase(). The public and system identifiers,systemId and publicId, are strings if given; if the public identifier is notgiven, publicId will be None. The context value is opaque and shouldonly be used as described below.

For external entities to be parsed, this handler must be implemented. It isresponsible for creating the sub-parser usingExternalEntityParserCreate(context), initializing it with the appropriatecallbacks, and parsing the entity. This handler should return an integer; if itreturns 0, the parser will raise anXML_ERROR_EXTERNAL_ENTITY_HANDLING error, otherwise parsing willcontinue.

If this handler is not provided, external entities are reported by theDefaultHandler callback, if provided.

19.15.2. ExpatError Exceptions¶

ExpatError exceptions have a number of interesting attributes:

Expat’s internal error number for the specific error. This will match one ofthe constants defined in the errors object from this module.

Line number on which the error was detected. The first line is numbered 1.

New in version 2.1.

Character offset into the line where the error occurred. The first column isnumbered 0.

19.15.3. Example¶

The following program defines three handlers that just print out theirarguments.

The output from this program is:

19.15.4. Content Model Descriptions¶

Content models are described using nested tuples. Each tuple contains fourvalues: the type, the quantifier, the name, and a tuple of children. Childrenare simply additional content model descriptions.

The values of the first two fields are constants defined in the model objectof the xml.parsers.expat module. These constants can be collected in twogroups: the model type group and the quantifier group.

The constants in the model type group are:

The element named by the model name was declared to have a content model ofANY.

The named element allows a choice from a number of options; this is used forcontent models such as (ABC).

Elements which are declared to be EMPTY have this model type.

xml.parsers.expat.XML_CTYPE_MIXED

xml.parsers.expat.XML_CTYPE_NAME

Models which represent a series of models which follow one after the other areindicated with this model type. This is used for models such as (A,B,C).

The constants in the quantifier group are:

No modifier is given, so it can appear exactly once, as for A.

The model is optional: it can appear once or not at all, as for A?.

The model must occur one or more times (like A+).

The model must occur zero or more times, as for A*.

19.15.5. Expat error constants¶

The following constants are provided in the errors object of thexml.parsers.expat module. These constants are useful in interpretingsome of the attributes of the ExpatError exception objects raised when anerror has occurred.

The errors object has the following attributes:

xml.parsers.expat.XML_ERROR_ASYNC_ENTITY

An entity reference in an attribute value referred to an external entity insteadof an internal entity.

A character reference referred to a character which is illegal in XML (forexample, character 0, or ‘�’).

An entity reference referred to an entity which was declared with a notation, socannot be parsed.

An attribute was used more than once in a start tag.

xml.parsers.expat.XML_ERROR_INCORRECT_ENCODING

Raised when an input byte could not properly be assigned to a character; forexample, a NUL byte (value 0) in a UTF-8 input stream.

Something other than whitespace occurred after the document element.

An XML declaration was found somewhere other than the start of the input data.

The document contains no elements (XML requires all documents to contain exactlyone top-level element).

Expat Library Not Found Machines

Expat was not able to allocate memory internally.

A parameter entity reference was found where it was not allowed.

An incomplete character was found in the input.

An entity reference contained another reference to the same entity; possibly viaa different name, and possibly indirectly.

Some unspecified syntax error was encountered.

An end tag did not match the innermost open start tag.

Some token (such as a start tag) was not closed before the end of the stream orthe next token was encountered.

A reference was made to an entity which was not defined.

3. Mac mp3 library manager. You can transfer iTunes music to your Android too.

The document encoding is not supported by Expat.

A CDATA marked section was not closed.

xml.parsers.expat.XML_ERROR_EXTERNAL_ENTITY_HANDLING

Expat Library Not Found Machine

The parser determined that the document was not “standalone” though it declareditself to be in the XML declaration, and the NotStandaloneHandler wasset and returned 0.

xml.parsers.expat.XML_ERROR_UNEXPECTED_STATE

xml.parsers.expat.XML_ERROR_ENTITY_DECLARED_IN_PE

An operation was requested that requires DTD support to be compiled in, butExpat was configured without DTD support. This should never be reported by astandard build of the xml.parsers.expat module.

A behavioral change was requested after parsing started that can only be changedbefore parsing has started. This is (currently) only raised byUseForeignDTD().

An undeclared prefix was found when namespace processing was enabled.

The document attempted to remove the namespace declaration associated with aprefix.

A parameter entity contained incomplete markup.

The document contained no document element at all.

There was an error parsing a text declaration in an external entity.

Characters were found in the public id that are not allowed.

Expat Library Not Found Mac Os

The requested operation was made on a suspended parser, but isn’t allowed. Thisincludes attempts to provide additional input or to stop the parser.

An attempt to resume the parser was made when the parser had not been suspended.

This should not be reported to Python applications.

The requested operation was made on a parser which was finished parsing input,but isn’t allowed. This includes attempts to provide additional input or tostop the parser.

xml.parsers.expat.XML_ERROR_SUSPEND_PE
