Detailed Description

This class is a wrapper around a protobuf used to collect logging information. It also provides a simple aggregation mechanism for collecting the ids of applied rewriters.

Care and feeding of log records: (1) All logging must be done through log records. No class should have static members of any logging proto class. Log records can either create the logging protos, or will take ownership of them. (2) All access and manipulation of log data must be guarded by the log record's mutex. Commonly repeated logging operations should be factored into functions in this class (and be so guarded therein). (3) In most cases, log records should be created and owned by request contexts. Subclasses may wrap some other type of protobuf; they must still provide access to a LogRecord instance, however.


Constructor & Destructor Documentation

Construct a LogRecord with a new LoggingInfo proto and caller- supplied mutex. This class takes ownership of the mutex.

Non-initializing default constructor for subclasses. Subclasses that invoke this constructor should implement and call their own initializer that instantiates the wrapped logging proto and calls set_mutex with a valid Mutex object.


Member Function Documentation

void net_instaweb::LogRecord::AddFoundPropertyToCohortInfo ( int  index,
const GoogleString property 
)

Updates the cohort info at the specified index, to include the given property in the last of properties found in the cache.

For compatibility with older logging methods, returns a comma-joined string concatenating the sorted coalesced rewriter ids of APPLIED_OK entries in the rewriter_info array. Each id will appear once in the string if any number of successful rewrites for that id have been logged.

virtual LoggingInfo* net_instaweb::LogRecord::logging_info ( ) [virtual]

Return the LoggingInfo proto wrapped by this class. Calling code must guard any reads and writes to this using mutex().

void net_instaweb::LogRecord::LogJsDisableFilter ( const char *  id,
bool  has_pagespeed_no_defer 
)
Todo:
TODO(gee): Change the callsites.
void net_instaweb::LogRecord::LogRewriterApplicationStatus ( const char *  rewriter_id,
RewriterInfo::RewriterApplicationStatus  status 
)

Log the status of a rewriter application on a resource.

Todo:
TODO(gee): I'd really prefer rewriter_id was an enum.
void net_instaweb::LogRecord::LogRewriterHtmlStatus ( const char *  rewriter_id,
RewriterStats::RewriterHtmlStatus  status 
)

Log the HTML level status for a filter. This should be called only once per filter, at the point where it is determined the filter is either active or not.

Return the mutex associated with this instance. Calling code should guard reads and writes of LogRecords

RewriterInfo* net_instaweb::LogRecord::NewRewriterInfo ( const char *  rewriter_id)

Create a new rewriter logging submessage for |rewriter_id|, returning a pointer to it for later access. Note that this can return NULL if the size of rewriter_info has grown too large. It is the caller's responsibility to handle this safely.

void net_instaweb::LogRecord::SetAllowLoggingUrls ( bool  allow_logging_urls)

Sets whether urls should be logged. This could potentially generate a lot of logs data, so this should be switched on only for debugging.

Mutex-guarded log mutation convenience methods. The rule of thumb is that if a single-field update to a logging proto occurs multiple times, it should be factored out into a method on this class.

void net_instaweb::LogRecord::SetCacheStatusForCohortInfo ( int  index,
bool  found,
int  key_state 
)

Updates the cohort info at the specified index, to indicate whether it was a cache hit.

void net_instaweb::LogRecord::SetDeviceAndCacheTypeForCohortInfo ( int  index,
int  device_type,
int  cache_type 
)

Updates the cohort info at the specified index with the device and cache type.

void net_instaweb::LogRecord::SetLogUrlIndices ( bool  log_url_indices)

Sets whether URL indices should be logged for every rewriter application or not.

Sets the maximum number of RewriterInfo submessages that can accumulate in the LoggingInfo proto wrapped by this class.

void net_instaweb::LogRecord::SetRewriterLoggingStatus ( const char *  rewriter_id,
RewriterInfo::RewriterApplicationStatus  status 
)

Creates a new rewriter logging submessage for |rewriter_id|, and sets status it.

void net_instaweb::LogRecord::SetRewriterLoggingStatus ( const char *  rewriter_id,
const GoogleString url,
RewriterInfo::RewriterApplicationStatus  status 
)

Creates a new rewriter logging submessage for |rewriter_id|, sets status and the url index.

Sets time_to_start_fetch_ms in the TimingInfo submessage as an offset from timing_info.request_start_ms (|start_time_ms| is an absolute time value and is converted into the offset). If request_start_ms is unset, this is a silent no-op. This may be called several times in sucession, for example in the case of retried fetches. In that case, if time_to_start_fetch_ms has already been set in the log record, this is again a silent no-op.

Mutex-guarded log-writing operations. Derived classes should override Impl methods. Returns false if the log write attempt failed.

virtual bool net_instaweb::LogRecord::WriteLogImpl ( ) [inline, protected, virtual]

Implements writing a log, base implementation is a no-op. Returns false if writing failed.
