+// - Optionally, the fetch history can cache the ETagged data that was returned
+//   in the responses that contained Etag headers. If a later fetch
+//   results in a 304 status, the fetcher will return the cached ETagged data
+//   to the client along with a 200 status, hiding the 304.

+//
+//  GTMHTTPFetcher.h
+//
+
+// This is essentially a wrapper around NSURLConnection for POSTs and GETs.
+// If setPostData: is called, then POST is assumed.
+//
+// When would you use this instead of NSURLConnection?
+//
+// - When you just want the result from a GET, POST, or PUT
+// - When you want the "standard" behavior for connections (redirection handling
+//   an so on)
+// - When you want automatic retry on failures
+// - When you want to avoid cookie collisions with Safari and other applications
+// - When you are fetching resources with ETags and want to avoid the overhead
+//   of repeated fetches of unchanged data
+// - When you need to set a credential for the http operation
+//
+// This is assumed to be a one-shot fetch request; don't reuse the object
+// for a second fetch.
+//
+// The fetcher may be created auto-released, in which case it will release
+// itself after the fetch completion callback.  The fetcher is implicitly
+// retained as long as a connection is pending.
+//
+// But if you may need to cancel the fetcher, retain it and have the delegate
+// release the fetcher in the callbacks.
+//
+// Sample usage:
+//
+//  NSURLRequest *request = [NSURLRequest requestWithURL:myURL];
+//  GTMHTTPFetcher* myFetcher = [GTMHTTPFetcher fetcherWithRequest:request];
+//
+//  // optional upload body data
+//  [myFetcher setPostData:[postString dataUsingEncoding:NSUTF8StringEncoding]];
+//
+//  [myFetcher beginFetchWithDelegate:self
+//                  didFinishSelector:@selector(myFetcher:finishedWithData:error:)];
+//
+//  Upon fetch completion, the callback selector is invoked; it should have
+//  this signature (you can use any callback method name you want so long as
+//  the signature matches this):
+//
+//  - (void)myFetcher:(GTMHTTPFetcher *)fetcher finishedWithData:(NSData *)retrievedData error:(NSError *)error;
+//
+//  The block callback version looks like:
+//
+//  [myFetcher beginFetchWithCompletionHandler:^(NSData *retrievedData, NSError *error) {
+//    if (error != nil) {
+//      // status code or network error
+//    } else {
+//      // succeeded
+//    }
+//  }];
+
+//
+// NOTE:  Fetches may retrieve data from the server even though the server
+//        returned an error.  The failure selector is called when the server
+//        status is >= 300, with an NSError having domain
+//        kGTMHTTPFetcherStatusDomain and code set to the server status.
+//
+//        Status codes are at <http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html>
+//
+//
+// Downloading to disk:
+//
+// To have downloaded data saved directly to disk, specify either a path for the
+// downloadPath property, or a file handle for the downloadFileHandle property.
+// When downloading to disk, callbacks will be passed a nil for the NSData*
+// arguments.
+//
+//
+// HTTP methods and headers:
+//
+// Alternative HTTP methods, like PUT, and custom headers can be specified by
+// creating the fetcher with an appropriate NSMutableURLRequest
+//
+//
+// Proxies:
+//
+// Proxy handling is invisible so long as the system has a valid credential in
+// the keychain, which is normally true (else most NSURL-based apps would have
+// difficulty.)  But when there is a proxy authetication error, the the fetcher
+// will call the failedWithError: method with the NSURLChallenge in the error's
+// userInfo. The error method can get the challenge info like this:
+//
+//  NSURLAuthenticationChallenge *challenge
+//     = [[error userInfo] objectForKey:kGTMHTTPFetcherErrorChallengeKey];
+//  BOOL isProxyChallenge = [[challenge protectionSpace] isProxy];
+//
+// If a proxy error occurs, you can ask the user for the proxy username/password
+// and call fetcher's setProxyCredential: to provide those for the
+// next attempt to fetch.
+//
+//
+// Cookies:
+//
+// There are three supported mechanisms for remembering cookies between fetches.
+//
+// By default, GTMHTTPFetcher uses a mutable array held statically to track
+// cookies for all instantiated fetchers. This avoids server cookies being set
+// by servers for the application from interfering with Safari cookie settings,
+// and vice versa.  The fetcher cookies are lost when the application quits.
+//
+// To rely instead on WebKit's global NSHTTPCookieStorage, call
+// setCookieStorageMethod: with kGTMHTTPFetcherCookieStorageMethodSystemDefault.
+//
+// If the fetcher is created from a GTMHTTPFetcherService object
+// then the cookie storage mechanism is set to use the cookie storage in the
+// service object rather than the static storage.
+//
+//
+// Fetching for periodic checks:
+//
+// The fetcher object tracks ETag headers from responses and
+// provide an "If-None-Match" header. This allows the server to save
+// bandwidth by providing a status message instead of repeated response
+// data.
+//
+// To get this behavior, create the fetcher from an GTMHTTPFetcherService object
+// and look for a fetch callback error with code 304
+// (kGTMHTTPFetcherStatusNotModified) like this:
+//
+// - (void)myFetcher:(GTMHTTPFetcher *)fetcher finishedWithData:(NSData *)data error:(NSError *)error {
+//    if ([error code] == kGTMHTTPFetcherStatusNotModified) {
+//      // |data| is empty; use the data from the previous finishedWithData: for this URL
+//    } else {
+//      // handle other server status code
+//    }
+// }
+//
+//
+// Monitoring received data
+//
+// The optional received data selector can be set with setReceivedDataSelector:
+// and should have the signature
+//
+//  - (void)myFetcher:(GTMHTTPFetcher *)fetcher receivedData:(NSData *)dataReceivedSoFar;
+//
+// The number bytes received so far is available as [fetcher downloadedLength].
+// This number may go down if a redirect causes the download to begin again from
+// a new server.
+//
+// If supplied by the server, the anticipated total download size is available
+// as [[myFetcher response] expectedContentLength] (and may be -1 for unknown
+// download sizes.)
+//
+//
+// Automatic retrying of fetches
+//
+// The fetcher can optionally create a timer and reattempt certain kinds of
+// fetch failures (status codes 408, request timeout; 503, service unavailable;
+// 504, gateway timeout; networking errors NSURLErrorTimedOut and
+// NSURLErrorNetworkConnectionLost.)  The user may set a retry selector to
+// customize the type of errors which will be retried.
+//
+// Retries are done in an exponential-backoff fashion (that is, after 1 second,
+// 2, 4, 8, and so on.)
+//
+// Enabling automatic retries looks like this:
+//  [myFetcher setRetryEnabled:YES];
+//
+// With retries enabled, the success or failure callbacks are called only
+// when no more retries will be attempted. Calling the fetcher's stopFetching
+// method will terminate the retry timer, without the finished or failure
+// selectors being invoked.
+//
+// Optionally, the client may set the maximum retry interval:
+//  [myFetcher setMaxRetryInterval:60.0]; // in seconds; default is 60 seconds
+//                                        // for downloads, 600 for uploads
+//
+// Also optionally, the client may provide a callback selector to determine
+// if a status code or other error should be retried.
+//  [myFetcher setRetrySelector:@selector(myFetcher:willRetry:forError:)];
+//
+// If set, the retry selector should have the signature:
+//   -(BOOL)fetcher:(GTMHTTPFetcher *)fetcher willRetry:(BOOL)suggestedWillRetry forError:(NSError *)error
+// and return YES to set the retry timer or NO to fail without additional
+// fetch attempts.
+//
+// The retry method may return the |suggestedWillRetry| argument to get the
+// default retry behavior.  Server status codes are present in the
+// error argument, and have the domain kGTMHTTPFetcherStatusDomain. The
+// user's method may look something like this:
+//
+//  -(BOOL)myFetcher:(GTMHTTPFetcher *)fetcher willRetry:(BOOL)suggestedWillRetry forError:(NSError *)error {
+//
+//    // perhaps examine [error domain] and [error code], or [fetcher retryCount]
+//    //
+//    // return YES to start the retry timer, NO to proceed to the failure
+//    // callback, or |suggestedWillRetry| to get default behavior for the
+//    // current error domain and code values.
+//    return suggestedWillRetry;

+
+// Key Abstractions
+// ----------------
+//
+// This file declares multiple classes and protocols that are used by the
+// GTMLogger logging system. The 4 main abstractions used in this file are the
+// following:
+//
+//   * logger (GTMLogger) - The main logging class that users interact with. It
+//   has methods for logging at different levels and uses a log writer, a log
+//   formatter, and a log filter to get the job done.
+//
+//   * log writer (GTMLogWriter) - Writes a given string to some log file, where
+//   a "log file" can be a physical file on disk, a POST over HTTP to some URL,
+//   or even some in-memory structure (e.g., a ring buffer).
+//
+//   * log formatter (GTMLogFormatter) - Given a format string and arguments as
+//   a va_list, returns a single formatted NSString. A "formatted string" could
+//   be a string with the date prepended, a string with values in a CSV format,
+//   or even a string of XML.
+//
+//   * log filter (GTMLogFilter) - Given a formatted log message as an NSString
+//   and the level at which the message is to be logged, this class will decide
+//   whether the given message should be logged or not. This is a flexible way
+//   to filter out messages logged at a certain level, messages that contain
+//   certain text, or filter nothing out at all. This gives the caller the
+//   flexibility to dynamically enable debug logging in Release builds.
+//
+// This file also declares some classes to handle the common log writer, log
+// formatter, and log filter cases. Callers can also create their own writers,
+// formatters, and filters and they can even build them on top of the ones
+// declared here. Keep in mind that your custom writer/formatter/filter may be
+// called from multiple threads, so it must be thread-safe.
+
+#import <Foundation/Foundation.h>
+#import "GTMDefines.h"
+
+// Predeclaration of used protocols that are declared later in this file.
+@protocol GTMLogWriter, GTMLogFormatter, GTMLogFilter;
+
+// GTMLogger
+//
+// GTMLogger is the primary user-facing class for an object-oriented logging
+// system. It is built on the concept of log formatters (GTMLogFormatter), log
+// writers (GTMLogWriter), and log filters (GTMLogFilter). When a message is
+// sent to a GTMLogger to log a message, the message is formatted using the log
+// formatter, then the log filter is consulted to see if the message should be
+// logged, and if so, the message is sent to the log writer to be written out.
+//
+// GTMLogger is intended to be a flexible and thread-safe logging solution. Its
+// flexibility comes from the fact that GTMLogger instances can be customized
+// with user defined formatters, filters, and writers. And these writers,
+// filters, and formatters can be combined, stacked, and customized in arbitrary
+// ways to suit the needs at hand. For example, multiple writers can be used at
+// the same time, and a GTMLogger instance can even be used as another
+// GTMLogger's writer. This allows for arbitrarily deep logging trees.
+//
+// A standard GTMLogger uses a writer that sends messages to standard out, a
+// formatter that smacks a timestamp and a few other bits of interesting
+// information on the message, and a filter that filters out debug messages from
+// release builds. Using the standard log settings, a log message will look like
+// the following:
+//
+//   2007-12-30 10:29:24.177 myapp[4588/0xa07d0f60] [lvl=1] foo=<Foo: 0x123>
+//
+// The output contains the date and time of the log message, the name of the
+// process followed by its process ID/thread ID, the log level at which the
+// message was logged (in the previous example the level was 1:
+// kGTMLoggerLevelDebug), and finally, the user-specified log message itself (in
+// this case, the log message was @"foo=%@", foo).
+//
+// Multiple instances of GTMLogger can be created, each configured their own
+// way.  Though GTMLogger is not a singleton (in the GoF sense), it does provide
+// access to a shared (i.e., globally accessible) GTMLogger instance. This makes
+// it convenient for all code in a process to use the same GTMLogger instance.
+// The shared GTMLogger instance can also be configured in an arbitrary, and
+// these configuration changes will affect all code that logs through the shared
+// instance.
+
+//
+// Log Levels
+// ----------
+// GTMLogger has 3 different log levels: Debug, Info, and Error. GTMLogger
+// doesn't take any special action based on the log level; it simply forwards
+// this information on to formatters, filters, and writers, each of which may
+// optionally take action based on the level. Since log level filtering is
+// performed at runtime, log messages are typically not filtered out at compile
+// time.  The exception to this rule is that calls to the GTMLoggerDebug() macro
+// *ARE* filtered out of non-DEBUG builds. This is to be backwards compatible
+// with behavior that many developers are currently used to. Note that this
+// means that GTMLoggerDebug(@"hi") will be compiled out of Release builds, but
+// [[GTMLogger sharedLogger] logDebug:@"hi"] will NOT be compiled out.
+//
+// Standard loggers are created with the GTMLogLevelFilter log filter, which
+// filters out certain log messages based on log level, and some other settings.
+//
+// In addition to the -logDebug:, -logInfo:, and -logError: methods defined on
+// GTMLogger itself, there are also C macros that make usage of the shared
+// GTMLogger instance very convenient. These macros are:
+//
+//   GTMLoggerDebug(...)
+//   GTMLoggerInfo(...)
+//   GTMLoggerError(...)
+//
+// Again, a notable feature of these macros is that GTMLogDebug() calls *will be
+// compiled out of non-DEBUG builds*.
+//
+// Standard Loggers
+// ----------------
+// GTMLogger has the concept of "standard loggers". A standard logger is simply
+// a logger that is pre-configured with some standard/common writer, formatter,
+// and filter combination. Standard loggers are created using the creation
+// methods beginning with "standard". The alternative to a standard logger is a
+// regular logger, which will send messages to stdout, with no special
+// formatting, and no filtering.
+//
+// How do I use GTMLogger?
+// ----------------------
+// The typical way you will want to use GTMLogger is to simply use the
+// GTMLogger*() macros for logging from code. That way we can easily make
+// changes to the GTMLogger class and simply update the macros accordingly. Only
+// your application startup code (perhaps, somewhere in main()) should use the
+// GTMLogger class directly in order to configure the shared logger, which all
+// of the code using the macros will be using. Again, this is just the typical
+// situation.
+//
+// To be complete, there are cases where you may want to use GTMLogger directly,
+// or even create separate GTMLogger instances for some reason. That's fine,
+// too.
+//
+// Examples
+// --------
+// The following show some common GTMLogger use cases.
+//
+// 1. You want to log something as simply as possible. Also, this call will only
+//    appear in debug builds. In non-DEBUG builds it will be completely removed.
+//
+//      GTMLoggerDebug(@"foo = %@", foo);
+//
+// 2. The previous example is similar to the following. The major difference is
+//    that the previous call (example 1) will be compiled out of Release builds
+//    but this statement will not be compiled out.
+//
+//      [[GTMLogger sharedLogger] logDebug:@"foo = %@", foo];
+//
+// 3. Send all logging output from the shared logger to a file. We do this by
+//    creating an NSFileHandle for writing associated with a file, and setting
+//    that file handle as the logger's writer.
+//
+//      NSFileHandle *f = [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log"
+//                                                          create:YES];
+//      [[GTMLogger sharedLogger] setWriter:f];
+//      GTMLoggerError(@"hi");  // This will be sent to /tmp/f.log
+//
+// 4. Create a new GTMLogger that will log to a file. This example differs from
+//    the previous one because here we create a new GTMLogger that is different
+//    from the shared logger.
+//
+//      GTMLogger *logger = [GTMLogger standardLoggerWithPath:@"/tmp/temp.log"];
+//      [logger logInfo:@"hi temp log file"];
+//
+// 5. Create a logger that writes to stdout and does NOT do any formatting to
+//    the log message. This might be useful, for example, when writing a help
+//    screen for a command-line tool to standard output.
+//
+//      GTMLogger *logger = [GTMLogger logger];
+//      [logger logInfo:@"%@ version 0.1 usage", progName];
+//
+// 6. Send log output to stdout AND to a log file. The trick here is that
+//    NSArrays function as composite log writers, which means when an array is
+//    set as the log writer, it forwards all logging messages to all of its
+//    contained GTMLogWriters.
+//
+//      // Create array of GTMLogWriters
+//      NSArray *writers = [NSArray arrayWithObjects:
+//          [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log" create:YES],
+//          [NSFileHandle fileHandleWithStandardOutput], nil];
+//
+//      GTMLogger *logger = [GTMLogger standardLogger];
+//      [logger setWriter:writers];
+//      [logger logInfo:@"hi"];  // Output goes to stdout and /tmp/f.log
+//
+// For futher details on log writers, formatters, and filters, see the
+// documentation below.
+//
+// NOTE: GTMLogger is application level logging.  By default it does nothing
