-**|
-**|| Grow(): a method for requesting that a yarn instance be made

-**| (Note that no nsIMdbEnv instance is passed as argument, although one
-**| might be needed in some circumstances. So if an nsIMdbEnv is needed,
-**| a reference to one might be held inside a mdbYarn member slot.)
-**|
-**|| self: a yarn instance to be grown. Presumably this yarn is
-**| the instance which holds the mYarn_Grow method pointer. Yarn
-**| instancesshould only be passed to grow methods which they were
-**| specifically designed to fit, as indicated by the mYarn_Grow slot.
-**|
-**|| inNewSize: the new desired value for slot mYarn_Size in self.
-**| If mYarn_Size is already this big, then nothing should be done.
-**| If inNewSize is larger than seems feasible or desirable to honor,
-**| then any size restriction policy can be used to grow to some size
-**| greater than mYarn_Size. (Grow() might even grow to a size
-**| greater than inNewSize in order to make the increase in size seem
-**| worthwhile, rather than growing in many smaller steps over time.)

-typedef void (* mdbYarn_mGrow)(mdbYarn* self, mdb_size inNewSize);
-// mdbYarn_mGrow methods must be declared with C linkage in C++

-/*| mdbYarn: a variable length "string" of arbitrary binary bytes,
-**| whose length is mYarn_Fill, inside a buffer mYarn_Buf that has
-**| at most mYarn_Size byte of physical space.
-**|
-**|| mYarn_Buf: a pointer to space containing content. This slot
-**| might never be nil when mYarn_Size is nonzero, but checks for nil
-**| are recommended anyway.
-**| (Implementations of mdbYarn_mGrow methods should take care to
-**| ensure the existence of a replacement before dropping old Bufs.)
-**| Content in Buf can be anything in any format, but the mYarn_Form
-**| implies the actual format by some caller-to-callee convention.
-**| mYarn_Form==0 implies US-ASCII iso-8859-1 Latin1 string content.
-**|
-**|| mYarn_Size: the physical size of Buf in bytes. Note that if one
-**| intends to terminate a string with a null byte, that it must not
-**| be written at or after mYarn_Buf[mYarn_Size] because this is after
-**| the last byte in the physical buffer space. Size can be zero,
-**| which means the string has no content whatsoever; note that when
-**| Size is zero, this is a suitable reason for Buf==nil as well.
-**|
-**|| mYarn_Fill: the logical content in Buf in bytes, where Fill must
-**| never exceed mYarn_Size. Note that yarn strings might not have a
-**| terminating null byte (since they might not even be C strings), but
-**| when they do, such terminating nulls are considered part of content
-**| and therefore Fill will count such null bytes. So an "empty" C
-**| string will have Fill==1, because content includes one null byte.
-**| Fill does not mean "length" when applied to C strings for this
-**| reason. However, clients using yarns to hold C strings can infer
-**| that length is equal to Fill-1 (but should take care to handle the
-**| case where Fill==0). To be paranoid, one can always copy to a
-**| destination with size exceeding Fill, and place a redundant null
-**| byte in the Fill position when this simplifies matters.
-**|
-**|| mYarn_Form: a designation of content format within mYarn_Buf.
-**| The semantics of this slot are the least well defined, since the
-**| actual meaning is context dependent, to the extent that callers
-**| and callees must agree on format encoding conventions when such
-**| are not standardized in many computing contexts. However, in the
-**| context of a specific mdb database, mYarn_Form is a token for an
-**| atomized string in that database that typically names a preferred
-**| mime type charset designation. If and when mdbYarn is used for
-**| other purposes away from the mdb interface, folks can use another
-**| convention system for encoding content formats. However, in all
-**| contexts is it useful to maintain the convention that Form==0
-**| implies Buf contains US-ASCII iso-8859-1 Latin1 string content.
-**|
-**|| mYarn_Grow: either a mdbYarn_mGrow method, or else nil. When
-**| a mdbYarn_mGrow method is provided, this method can be used to
-**| request a yarn buf size increase. A caller who constructs the
-**| original mdbYarn instance decides whether a grow method is necessary
-**| or desirable, and uses only grow methods suitable for the buffering
-**| nature of a specific mdbYarn instance. (For example, Buf might be a
-**| staticly allocated string space which switches to something heap-based
-**| when grown, and subsequent calls to grow the yarn must distinguish the
-**| original static string from heap allocated space, etc.) Note that the
-**| method stored in mYarn_Grow can change, and this might be a common way
-**| to track memory managent changes in policy for mYarn_Buf.

-**| Callers are expected to maintain one or more row instances as a buffer
-**| for staging cell content copied into or out of a table inside the db.
-**| Callers are urged to use an instance of nsIMdbRow created by the nsIMdbFactory
-**| code suite, because reading and writing might be much more efficient than
-**| when using a hand-rolled nsIMdbRow subclass with no relation to the suite.
-**|
-**|| ports: a port is a readonly interface to a specific database file. Most
-**| of the methods to access a db file are suitable for a readonly interface,
-**| so a port is the basic minimum for accessing content. This makes it
-**| possible to read other external formats for import purposes, without
-**| needing the code or competence necessary to write every such format. So
-**| we can write generic import code just once, as long as every format can
-**| show a face based on nsIMdbPort. (However, same suite import can be faster.)
-**| Given a file name and the first 512 bytes of a file, a factory can say if
-**| a port can be opened by this factory. Presumably an app maintains chains
-**| of factories for different suites, and asks each in turn about opening a
-**| a prospective file for reading (as a port) or writing (as a store). I'm
-**| not ready to tackle issues of format fidelity and factory chain ordering.
-**|
-**|| stores: a store is a mutable interface to a specific database file, and
-**| includes the port interface plus any methods particular to writing, which
-**| are few in number. Presumably the set of files that can be opened as
-**| stores is a subset of the set of files that can be opened as ports. A
-**| new store can be created with CreateNewFileStore() by supplying a new
-**| file name which does not yet exist (callers are always responsible for
-**| destroying any existing files before calling this method).

-/*| nsIMdbPort: a readonly interface to a specific database file. The mutable
-**| nsIMdbStore interface is a subclass that includes writing behavior, but
-**| most of the needed db methods appear in the readonly nsIMdbPort interface.
-**|
-**|| mdbYarn: note all nsIMdbPort and nsIMdbStore subclasses must guarantee null
-**| termination of all strings written into mdbYarn instances, as long as
-**| mYarn_Size and mYarn_Buf are nonzero. Even truncated string values must
-**| be null terminated. This is more strict behavior than mdbYarn requires,
-**| but it is part of the nsIMdbPort and nsIMdbStore interface.
-**|
-**|| attributes: methods are provided to distinguish a readonly port from a
-**| mutable store, and whether a mutable store actually has any dirty content.
-**|
-**|| filepath: the file path used to open the port from the nsIMdbFactory can be
-**| queried and discovered by GetPortFilePath(), which includes format info.
-**|
-**|| export: a port can write itself in other formats, with perhaps a typical
-**| emphasis on text interchange formats used by other systems. A port can be
-**| queried to determine its preferred export interchange format, and a port
-**| can be queried to see whether a specific export format is supported. And
-**| actually exporting a port requires a new destination file name and format.
-**|
-**|| tokens: a port supports queries about atomized strings to map tokens to
-**| strings or strings to token integers. (All atomized strings must be in
-**| US-ASCII iso-8859-1 Latin1 charset encoding.) When a port is actually a
-**| mutable store and a string has not yet been atomized, then StringToToken()
-**| will actually do so and modify the store. The QueryToken() method will not
-**| atomize a string if it has not already been atomized yet, even in stores.
-**|
-**|| tables: other than string tokens, all port content is presented through
-**| tables, which are ordered collections of rows. Tables are identified by
-**| row scope and table kind, which might or might not be unique in a port,
-**| depending on app convention. When tables are effectively unique, then
-**| queries for specific scope and kind pairs will find those tables. To see
-**| all tables that match specific row scope and table kind patterns, even in
-**| the presence of duplicates, every port supports a GetPortTableCursor()
-**| method that returns an iterator over all matching tables. Table kind is
-**| considered scoped inside row scope, so passing a zero for table kind will
-**| find all table kinds for some nonzero row scope. Passing a zero for row
-**| scope will iterate over all tables in the port, in some undefined order.
-**| (A new table can be added to a port using nsIMdbStore::NewTable(), even when
-**| the requested scope and kind combination is already used by other tables.)
-**|
-**|| memory: callers can request that a database use less memory footprint in
-**| several flavors, from an inconsequential idle flavor to a rather drastic
-**| panic flavor. Callers might perform an idle purge very frequently if desired
-**| with very little cost, since only normally scheduled memory management will
-**| be conducted, such as freeing resources for objects scheduled to be dropped.
-**| Callers should perform session memory purges infrequently because they might
-**| involve costly scanning of data structures to removed cached content, and
-**| session purges are recommended only when a caller experiences memory crunch.
-**| Callers should only rarely perform a panic purge, in response to dire memory
-**| straits, since this is likely to make db operations much more expensive
-**| than they would be otherwise. A panic purge asks a database to free as much
-**| memory as possible while staying effective and operational, because a caller
-**| thinks application failure might otherwise occur. (Apps might better close
-**| an open db, so panic purges only make sense when a db is urgently needed.)

- // CompressCommit() is called, because that percentage of the file seems
- // to be recoverable free space. The granularity is only in terms of
- // percentage points, and any value over 100 is considered equal to 100.
- //
- // If a store only has an approximate idea how much space might be saved
- // during a compress, then a best guess should be made. For example, the
- // Mork implementation might keep track of how much file space began with
- // text content before the first updating transaction, and then consider
- // all content following the start of the first transaction as potentially
- // wasted space if it is all updates and not just new content. (This is
- // a safe assumption in the sense that behavior will stabilize on a low
- // estimate of wastage after a commit removes all transaction updates.)
- //
- // Some db formats might attempt to keep a very accurate reckoning of free
- // space size, so a very accurate determination can be made. But other db
- // formats might have difficulty determining size of free space, and might
- // require some lengthy calculation to answer. This is the reason for
- // passing in the percentage threshold of interest, so that such lengthy
- // computations can terminate early as soon as at least inPercentWaste is
- // found, so that the entire file need not be groveled when unnecessary.
- // However, we hope implementations will always favor fast but imprecise
- // heuristic answers instead of extremely slow but very precise answers.
- //
- // If the outActualWaste parameter is non-nil, it will be used to return
- // the actual estimated space wasted as a percentage of file size. (This
- // parameter is provided so callers need not call repeatedly with altered
- // inPercentWaste values to isolate the actual wastage figure.) Note the
- // actual wastage figure returned can exactly equal inPercentWaste even
- // when this grossly underestimates the real figure involved, if the db
- // finds it very expensive to determine the extent of wastage after it is
- // known to at least exceed inPercentWaste. Note we expect that whenever
- // outShould returns true, that outActualWaste returns >= inPercentWaste.
- //
- // The effect of different inPercentWaste values is not very uniform over
- // the permitted range. For example, 50 represents 50% wastage, or a file
- // that is about double what it should be ideally. But 99 represents 99%
- // wastage, or a file that is about ninety-nine times as big as it should
- // be ideally. In the smaller direction, 25 represents 25% wastage, or
- // a file that is only 33% larger than it should be ideally.
- //
- // Callers can determine what policy they want to use for considering when
- // a file holds too much wasted space, and express this as a percentage
- // of total file size to pass as in the inPercentWaste parameter. A zero
- // likely returns always trivially true, and 100 always trivially false.
- // The great majority of callers are expected to use values from 25 to 75,
- // since most plausible thresholds for compressing might fall between the
- // extremes of 133% of ideal size and 400% of ideal size. (Presumably the
- // larger a file gets, the more important the percentage waste involved, so
- // a sliding scale for compress thresholds might use smaller numbers for
- // much bigger file sizes.)

-/*| nsIMdbStore: a mutable interface to a specific database file.
-**|
-**|| tables: one can force a new table to exist in a store with NewTable()
-**| and nonzero values for both row scope and table kind. (If one wishes only
-**| one table of a certain kind, then one might look for it first using the
-**| GetTableKind() method). One can pass inMustBeUnique to force future
-**| users of this store to be unable to create other tables with the same pair
-**| of scope and kind attributes. When inMustBeUnique is true, and the table
-**| with the given scope and kind pair already exists, then the existing one
-**| is returned instead of making a new table. Similarly, if one passes false
-**| for inMustBeUnique, but the table kind has already been marked unique by a
-**| previous user of the store, then the existing unique table is returned.
-**|
-**|| import: all or some of another port's content can be imported by calling
-**| AddPortContent() with a row scope identifying the extent of content to
-**| be imported. A zero row scope will import everything. A nonzero row
-**| scope will only import tables with a matching row scope. Note that one
-**| must somehow find a way to negotiate possible conflicts between existing
-**| row content and imported row content, and this involves a specific kind of
-**| definition for row identity involving either row IDs or unique attributes,
-**| or some combination of these two. At the moment I am just going to wave
-**| my hands, and say the default behavior is to assign all new row identities
-**| to all imported content, which will result in no merging of content; this
-**| must change later because it is unacceptable in some contexts.
-**|
-**|| commits: to manage modifications in a mutable store, very few methods are
-**| really needed to indicate global policy choices that are independent of
-**| the actual modifications that happen in objects at the level of tables,
-**| rows, and cells, etc. The most important policy to specify is which sets
-**| of changes are considered associated in a manner such that they should be
-**| applied together atomically to a given store. We call each such group of
-**| changes a transaction. We handle three different grades of transaction,
-**| but they differ only in semantic significance to the application, and are
-**| not intended to nest. (If small transactions were nested inside large
-**| transactions, that would imply that a single large transaction must be
-**| atomic over all the contained small transactions; but actually we intend
-**| smalls transaction never be undone once commited due to, say, aborting a
-**| transaction of greater significance.) The small, large, and session level
-**| commits have equal granularity, and differ only in risk of loss from the
-**| perspective of an application. Small commits characterize changes that
-**| can be lost with relatively small risk, so small transactions can delay
-**| until later if they are expensive or impractical to commit. Large commits
-**| involve changes that would probably inconvenience users if lost, so the
-**| need to pay costs of writing is rather greater than with small commits.
-**| Session commits are last ditch attempts to save outstanding changes before
-**| stopping the use of a particular database, so there will be no later point
-**| in time to save changes that have been delayed due to possible high cost.
-**| If large commits are never delayed, then a session commit has about the
-**| same performance effect as another large commit; but if small and large
-**| commits are always delayed, then a session commit is likely to be rather
-**| expensive as a runtime cost compared to any earlier database usage.
-**|
-**|| aborts: the only way to abort changes to a store is by closing the store.
-**| So there is no specific method for causing any abort. Stores must discard
-**| all changes made that are uncommited when a store is closed. This design
-**| choice makes the implementations of tables, rows, and cells much less
-**| complex because they need not maintain a record of undobable changes. When
-**| a store is closed, presumably this precipitates the closure of all tables,
-**| rows, and cells in the store as well. So an application can revert the
-**| state of a store in the user interface by quietly closing and reopening a
-**| store, because this will discard uncommited changes and show old content.
-**| This implies an app that closes a store will need to send a "scramble"
-**| event notification to any views that depend on old discarded content.

-/*| nsIMdbCollection: an object that collects a set of other objects as members.
-**| The main purpose of this base class is to unify the perceived semantics
-**| of tables and rows where their collection behavior is similar. This helps
-**| isolate the mechanics of collection behavior from the other semantics that
-**| are more characteristic of rows and tables.
-**|
-**|| count: the number of objects in a collection is the member count. (Some
-**| collection interfaces call this attribute the 'size', but that can be a
-**| little ambiguous, and counting actual members is harder to confuse.)
-**|
-**|| seed: the seed of a collection is a counter for changes in membership in
-**| a specific collection. This seed should change when members are added to
-**| or removed from a collection, but not when a member changes internal state.
-**| The seed should also change whenever the internal collection of members has
-**| a complex state change that reorders member positions (say by sorting) that
-**| would affect the nature of an iteration over that collection of members.
-**| The purpose of a seed is to inform any outstanding collection cursors that
-**| they might be stale, without incurring the cost of broadcasting an event
-**| notification to such cursors, which would need more data structure support.
-**| Presumably a cursor in a particular mdb code suite has much more direct
-**| access to a collection seed member slot that this abstract COM interface,
-**| so this information is intended more for clients outside mdb that want to
-**| make inferences similar to those made by the collection cursors. The seed
-**| value as an integer magnitude is not very important, and callers should not
-**| assume meaningful information can be derived from an integer value beyond
-**| whether it is equal or different from a previous inspection. A seed uses
-**| integers of many bits in order to make the odds of wrapping and becoming
-**| equal to an earlier seed value have probability that is vanishingly small.
-**|
-**|| port: every collection is associated with a specific database instance.
-**|
-**|| cursor: a subclass of nsIMdbCursor suitable for this specific collection
-**| subclass. The ability to GetCursor() from the base nsIMdbCollection class
-**| is not really as useful as getting a more specifically typed cursor more
-**| directly from the base class without any casting involved. So including
-**| this method here is more for conceptual illustration.
-**|
-**|| oid: every collection has an identity that persists from session to
-**| session. Implementations are probably able to distinguish row IDs from
-**| table IDs, but we don't specify anything official in this regard. A
-**| collection has the same identity for the lifetime of the collection,
-**| unless identity is swapped with another collection by means of a call to
-**| BecomeContent(), which is considered a way to swap a new representation
-**| for an old well-known object. (Even so, only content appears to change,
-**| while the identity seems to stay the same.)
-**|
-**|| become: developers can effectively cause two objects to swap identities,
-**| in order to effect a complete swap between what persistent content is
-**| represented by two oids. The caller should consider this a content swap,
-**| and not identity wap, because identities will seem to stay the same while
-**| only content changes. However, implementations will likely do this
-**| internally by swapping identities. Callers must swap content only
-**| between objects of similar type, such as a row with another row, and a
-**| table with another table, because implementations need not support
-**| cross-object swapping because it might break object name spaces.
-**|
-**|| dropping: when a caller expects a row or table will no longer be used, the
-**| caller can tell the collection to 'drop activity', which means the runtime
-**| object can have its internal representation purged to save memory or any
-**| other resource that is being consumed by the collection's representation.
-**| This has no effect on the collection's persistent content or semantics,
-**| and is only considered a runtime effect. After a collection drops
-**| activity, the object should still be as usable as before (because it has
-**| NOT been closed), but further usage can be expensive to re-instate because
-**| it might involve reallocating space and/or re-reading disk space. But
-**| since this future usage is not expected, the caller does not expect to
-**| pay the extra expense. An implementation can choose to implement
-**| 'dropping activity' in different ways, or even not at all if this
-**| operation is not really feasible. Callers cannot ask objects whether they
-**| are 'dropped' or not, so this should be transparent. (Note that
-**| implementors might fear callers do not really know whether future
-**| usage will occur, and therefore might delay the act of dropping until
-**| the near future, until seeing whether the object is used again
-**| immediately elsewhere. Such use soon after the drop request might cause
-**| the drop to be cancelled.)

-**| (A table with zero table kind is never allowed because this would make it
-**| ambiguous to use a zero table kind when iterating over tables in a port to
-**| indicate that all table kinds in a row scope should be seen by a cursor.)
-**|
-**|| port: every table is considered part of some port that contains the
-**| table, so that closing the containing port will cause the table to be
-**| indirectly closed as well. We make it easy to get the containing port for
-**| a table, because the port supports important semantic interfaces that will
-**| affect how content in table is presented; the most important port context
-**| that affects a table is specified by the set of token to string mappings
-**| that affect all tokens used throughout the database, and which drive the
-**| meanings of row scope, table kind, cell columns, etc.
-**|
-**|| cursor: a cursor that iterates over the rows in this table, where rows
-**| have zero-based index positions from zero to count-1. Making a cursor
-**| with negative position will next iterate over the first row in the table.
-**|
-**|| position: given any position from zero to count-1, a table will return
-**| the row ID and row scope for the row at that position. (One can use the
-**| GetRowAllCells() method to read that row, or else use a row cursor to both
-**| get the row at some position and read its content at the same time.) The
-**| position depends on whether a table is sorted, and upon the actual sort.
-**| Note that moving a row's position is only possible in unsorted tables.
-**|
-**|| row set: every table contains a collection of rows, where a member row is
-**| referenced by the table using the row ID and row scope for the row. No
-**| single table owns a given row instance, because rows are effectively ref-
-**| counted and destroyed only when the last table removes a reference to that
-**| particular row. (But a row can be emptied of all content no matter how
-**| many refs exist, and this might be the next best thing to destruction.)
-**| Once a row exists in a least one table (after NewRow() is called), then it
-**| can be added to any other table by calling AddRow(), or removed from any
-**| table by calling CutRow(), or queried as a member by calling HasRow(). A
-**| row can only be added to a table once, and further additions do nothing and
-**| complain not at all. Cutting a row from a table only does something when
-**| the row was actually a member, and otherwise does nothing silently.
-**|
-**|| row ref count: one can query the number of tables (and/or cells)
-**| containing a row as a member or a child.
-**|
-**|| row content: one can access or modify the cell content in a table's row
-**| by moving content to or from an instance of nsIMdbRow. Note that nsIMdbRow
-**| never represents the actual row inside a table, and this is the reason
-**| why nsIMdbRow instances do not have row IDs or row scopes. So an instance
-**| of nsIMdbRow always and only contains a snapshot of some or all content in
-**| past, present, or future persistent row inside a table. This means that
-**| reading and writing rows in tables has strictly copy semantics, and we
-**| currently do not plan any exceptions for specific performance reasons.
-**|
-**|| sorting: note all rows are assumed sorted by row ID as a secondary
-**| sort following the primary column sort, when table rows are sorted.
-**|
-**|| indexes:

- // avoid calling any method that would cause the state of this text object
- // to change (say by directly or indirectly setting the text to hold more
- // content that might grow the size of the buffer and free the old buffer).
- // In particular, callers should scrupulously avoid making calls into the
- // mdb interface to write any content while using the buffer pointer found
- // in the returned yarn instance. Best safe usage involves copying content
- // into some other kind of external content representation beyond mdb.
- //
- // (The original design of this method a week earlier included the concept
- // of very fast and efficient cooperative locking via a pointer to some lock
- // member slot. But let's ignore that complexity in the current design.)

- // AliasYarn() is specifically intended as the first step in transferring
- // content from nsIMdbBlob to a nsString representation, without forcing extra
- // allocations and/or memory copies. (A standard nsIMdbBlob_AsString() utility
- // will use AliasYarn() as the first step in setting a nsString instance.)
- //
- // This is an alternative to the GetYarn() method, which has copy semantics
- // only; AliasYarn() relaxes a robust safety principle only for performance
- // reasons, to accomodate the need for callers to transform text content to
- // some other canonical representation that would necessitate an additional
- // copy and transformation when such is incompatible with the mdbYarn format.
- //
- // The implementation of AliasYarn() should have extremely little overhead
- // besides the virtual dispatch to the method implementation, and the code
- // necessary to populate all the mdbYarn member slots with internal buffer
- // address and metainformation that describes the buffer content. Note that
- // mYarn_Grow must always be set to nil to indicate no resizing is allowed.

-**| A coil is a self-contained blob that knows how to grow itself as

-**| morkText to include the mText_Form slot, even though this won't be

-**| will stream bytes into this self-contained coil object. The name
-**| of this morkCoil class derives more from this intended usage than
-**| from anything else. The Mork code to parse db content will use
-**| coils with associated sinks to accumulate parsed strings.
-**|
-**|| Heap: this is the heap used for memory allocation. This instance
-**| is NOT refcounted, since this coil always assumes the heap is held
-**| through a reference elsewhere (for example, through the same object
-**| that contains or holds the coil itself. This lack of refcounting
-**| is consistent with the fact that morkCoil itself is not refcounted,
-**| and is not intended for use as a standalone object.

-/*| grow: make the map arrays bigger by 33%. The old map is completely
-**| full, or else we would not have called grow() to get more space. This
-**| means the free list is empty, and also means every old key and value is in
-**| use in the old arrays. So every key and value must be copied to the new
-**| arrays, and since they are contiguous in the old arrays, we can efficiently
-**| bitwise copy them in bulk from the old arrays to the new arrays, without
-**| paying any attention to the structure of the old arrays.
-**|
-**|| The content of the old bucket and assoc arrays need not be copied because
-**| this information is going to be completely rebuilt by rehashing all the
-**| keys into their new buckets, given the new larger map capacity. The new
-**| bucket array from new_arrays() is assumed to contain all zeroes, which is
-**| necessary to ensure the lists in each bucket stay null terminated as we
-**| build the new linked lists. (Note no old bucket ordering is preserved.)
-**|
-**|| If the old capacity is N, then in the new arrays the assocs with indexes
-**| from zero to N-1 are still allocated and must be rehashed into the map.
-**| The new free list contains all the following assocs, starting with the new
-**| assoc link at index N. (We call the links in the link array "assocs"
-**| because allocating a link is the same as allocating the key/value pair
-**| with the same index as the link.)
-**|
-**|| The new free list is initialized simply by pointing at the first new link
-**| in the assoc array after the size of the old assoc array. This assumes
-**| that FeHashTable_new_arrays() has already linked all the new assocs into a
-**| list with the first at the head of the list and the last at the tail of the
-**| list. So by making the free list point to the first of the new uncopied
-**| assocs, the list is already well-formed.

-**| each val is mMap_Form.mMapForm_ValSize in size. But the key and val
-**| slots are stored in separate arrays with indexes that are parallel to the

-
-/*| morkMid: an abstraction of all the variations we might need to support
-**| in order to present an ID through the parser interface most cheaply and
-**| with minimum transformation away from the original text format.
-**|
-**|| An ID can have one of four forms:
-**| 1) idHex (mMid_Oid.mOid_Id <- idHex)
-**| 2) idHex:^scopeHex (mMid_Oid.mOid_Id <- idHex, mOid_Scope <- scopeHex)
-**| 3) idHex:scopeName (mMid_Oid.mOid_Id <- idHex, mMid_Buf <- scopeName)
-**| 4) columnName (mMid_Buf <- columnName, for columns in cells only)
-**|
-**|| Typically, mMid_Oid.mOid_Id will hold a nonzero integer value for
-**| an ID, but we might have an optional scope specified by either an integer
-**| in hex format, or a string name. (Note that while the first ID can be
-**| scoped variably, any integer ID for a scope is assumed always located in
-**| the same scope, so the second ID need not be disambiguated.)
-**|
-**|| The only time mMid_Oid.mOid_Id is ever zero is when mMid_Buf alone
-**| is nonzero, to indicate an explicit string instead of an alias appeared.
-**| This case happens to make the representation of columns in cells somewhat
-**| easier to represent, since columns can just appear as a string name; and
-**| this unifies those interfaces with row and table APIs expecting IDs.
-**|

-/*| morkSink is intended to be a very cheap buffered i/o sink which
-**| writes to bufs and other strings a single byte at a time. The
-**| basic idea is that writing a single byte has a very cheap average
-**| cost, because a polymophic function call need only occur when the
-**| space between At and End is exhausted. The rest of the time a
-**| very cheap inline method will write a byte, and then bump a pointer.
-**|
-**|| At: the current position in some sequence of bytes at which to
-**| write the next byte put into the sink. Presumably At points into
-**| the private storage of some space which is not yet filled (except
-**| when At reaches End, and the overflow must then spill). Note both
-**| At and End are zeroed in the destructor to help show that a sink
-**| is no longer usable; this is safe because At==End causes the case
-**| where SpillPutc() is called to handled an exhausted buffer space.
-**|
-**|| End: an address one byte past the last byte which can be written
-**| without needing to make a buffer larger than previously. When At
-**| and End are equal, this means there is no space to write a byte,
-**| and that some underlying buffer space must be grown before another
-**| byte can be written. Note At must always be less than or equal to
-**| End, and otherwise an important invariant has failed severely.
-**|
-**|| Buf: this original class slot has been commented out in the new
-**| and more abstract version of this sink class, but the general idea
-**| behind this slot should be explained to help design subclasses.
-**| Each subclass should provide space into which At and End can point,
-**| where End is beyond the last writable byte, and At is less than or
-**| equal to this point inside the same buffer. With some kinds of
-**| medium, such as writing to an instance of morkBlob, it is feasible
-**| to point directly into the final resting place for all the content
-**| written to the medium. Other mediums such as files, which write
-**| only through function calls, will typically need a local buffer
-**| to efficiently accumulate many bytes between such function calls.
-**|
-**|| FlushSink: this flush method should move any buffered content to
-**| its final destination. For example, for buffered writes to a
-**| string medium, where string methods are function calls and not just
-**| inline macros, it is faster to accumulate many bytes in a small
-**| local buffer and then move these en masse later in a single call.
-**|
-**|| SpillPutc: when At is greater than or equal to End, this means an
-**| underlying buffer has become full, so the buffer must be flushed
-**| before a new byte can be written. The intention is that SpillPutc()
-**| will be equivalent to calling FlushSink() followed by another call
-**| to Putc(), where the flush is expected to make At less then End once
-**| again. Except that FlushSink() need not make the underlying buffer
-**| any larger, and SpillPutc() typically must make room for more bytes.
-**| Note subclasses might want to guard against the case that both At
-**| and End are null, which happens when a sink is destroyed, which sets
-**| both these pointers to null as an indication the sink is disabled.

- // not be persistent (but this seems desirable if it is cheap to do so).
- // Note that lazy index creation in readonly DBs is not very feasible.

- // This FindRow() interface assumes that attribute inColumn is effectively

- // so correct behavior is only guaranteed when no duplicates for this col
- // appear in the given set of rows. (If more than one row has the same cell
- // value in this column, no more than one will be found; and cutting one of
- // two duplicate rows can cause the index to assume no other such row lives
- // in the row space, so future calls return nil for negative search results
- // even though some duplicate row might still live within the rowspace.)
- //
- // In other words, the FindRow() implementation is allowed to assume simple
- // hash tables mapping unqiue column keys to associated row values will be
- // sufficient, where any duplication is not recorded because only one copy
- // of a given key need be remembered. Implementors are not required to sort

- // CompressCommit() is called, because that percentage of the file seems
- // to be recoverable free space. The granularity is only in terms of
- // percentage points, and any value over 100 is considered equal to 100.
- //
- // If a store only has an approximate idea how much space might be saved
- // during a compress, then a best guess should be made. For example, the
- // Mork implementation might keep track of how much file space began with
- // text content before the first updating transaction, and then consider
- // all content following the start of the first transaction as potentially
- // wasted space if it is all updates and not just new content. (This is
- // a safe assumption in the sense that behavior will stabilize on a low
- // estimate of wastage after a commit removes all transaction updates.)
- //
- // Some db formats might attempt to keep a very accurate reckoning of free
- // space size, so a very accurate determination can be made. But other db
- // formats might have difficulty determining size of free space, and might
- // require some lengthy calculation to answer. This is the reason for
- // passing in the percentage threshold of interest, so that such lengthy
- // computations can terminate early as soon as at least inPercentWaste is
- // found, so that the entire file need not be groveled when unnecessary.
- // However, we hope implementations will always favor fast but imprecise
- // heuristic answers instead of extremely slow but very precise answers.
- //
- // If the outActualWaste parameter is non-nil, it will be used to return
- // the actual estimated space wasted as a percentage of file size. (This
- // parameter is provided so callers need not call repeatedly with altered
- // inPercentWaste values to isolate the actual wastage figure.) Note the
- // actual wastage figure returned can exactly equal inPercentWaste even
- // when this grossly underestimates the real figure involved, if the db
- // finds it very expensive to determine the extent of wastage after it is
- // known to at least exceed inPercentWaste. Note we expect that whenever
- // outShould returns true, that outActualWaste returns >= inPercentWaste.
- //
- // The effect of different inPercentWaste values is not very uniform over
- // the permitted range. For example, 50 represents 50% wastage, or a file
- // that is about double what it should be ideally. But 99 represents 99%
- // wastage, or a file that is about ninety-nine times as big as it should
- // be ideally. In the smaller direction, 25 represents 25% wastage, or
- // a file that is only 33% larger than it should be ideally.
- //
- // Callers can determine what policy they want to use for considering when
- // a file holds too much wasted space, and express this as a percentage
- // of total file size to pass as in the inPercentWaste parameter. A zero
- // likely returns always trivially true, and 100 always trivially false.
- // The great majority of callers are expected to use values from 25 to 75,
- // since most plausible thresholds for compressing might fall between the
- // extremes of 133% of ideal size and 400% of ideal size. (Presumably the
- // larger a file gets, the more important the percentage waste involved, so
- // a sliding scale for compress thresholds might use smaller numbers for
- // much bigger file sizes.)

-/*=============================================================================
- * morkStream: buffered file i/o
- */
-
-/*| morkStream exists to define an morkFile subclass that provides buffered
-**| i/o for an underlying content file. Naturally this arrangement only makes
-**| sense when the underlying content file is itself not efficiently buffered
-**| (especially for character by character i/o).
-**|
-**|| morkStream is intended for either reading use or writing use, but not
-**| both simultaneously or interleaved. Pick one when the stream is created
-**| and don't change your mind. This restriction is intended to avoid obscure
-**| and complex bugs that might arise from interleaved reads and writes -- so
-**| just don't do it. A stream is either a sink or a source, but not both.
-**|
-**|| (When the underlying content file is intended to support both reading and
-**| writing, a developer might use two instances of morkStream where one is for
-**| reading and the other is for writing. In this case, a developer must take
-**| care to keep the two streams in sync because each will maintain a separate
-**| buffer representing a cache consistency problem for the other. A simple
-**| approach is to invalidate the buffer of one when one uses the other, with
-**| the assumption that closely mixed reading and writing is not expected, so
-**| that little cost is associated with changing read/write streaming modes.)
-**|
-**|| Exactly one of mStream_ReadEnd or mStream_WriteEnd must be a null pointer,
-**| and this will cause the right thing to occur when inlines use them, because
-**| mStream_At < mStream_WriteEnd (for example) will always be false and the
-**| else branch of the statement calls a function that raises an appropriate
-**| error to complain about either reading a sink or writing a source.
-**|
-**|| morkStream is a direct clone of ab_Stream from Communicator 4.5's
-**| address book code, which in turn was based on the stream class in the
-**| public domain Mithril programming language.

- // inspect the row membership and remove any duplicates; this can have big
- // impact if a collection holds tens of thousands of rows or more, when
- // the original cursor with dups simply referenced rows indirectly by row
- // position ranges, without using an explicit row set representation.
- // Callers are encouraged to use nsIMdbCursor::GetCount() to determine

-(I'm putting the text of this message in file morkWriter.cpp.)
-
-I'm making a change which should cause rows and tables to go away
-when a Mork db is compress committed, when the rows and tables
-are no longer needed. Because this is subtle, I'm describing it
-here in case misbehavior is ever observed. Otherwise you'll have
-almost no hope of fixing a related bug.
-
-This is done entirely in morkWriter.cpp: morkWriter::DirtyAll(),
-which currently marks all rows and tables dirty so they will be
-written in a later phase of the commit. My change is to merely
-selectively not mark certain rows and tables dirty, when they seem
-to be superfluous.
-
-A row is no longer needed when the mRow_GcUses slot hits zero, and
-this is used by the following inline morkRow method:
-
- mork_bool IsRowUsed() const { return mRow_GcUses != 0; }
-
-Naturally disaster ensues if mRow_GcUses is ever smaller than right.
-
-Similarly, we should drop tables when mTable_GcUses hits zero, but
-only when a table contains no row members. We consider tables to
-self reference (and prevent collection) when they contain content.
-Again, disaster ensues if mTable_GcUses is ever smaller than right.
-
- mork_count GetRowCount() const
- { return mTable_RowArray.mArray_Fill; }
-
- mork_bool IsTableUsed() const
- { return (mTable_GcUses != 0 || this->GetRowCount() != 0); }
-
-Now let's question why the design involves filtering what gets set
-to dirty. Why not apply a filter in the later phase when we write
-content? Because I'm afraid of missing some subtle interaction in
-updating table and row relationships. It seems safer to write a row
-or table when it starts out dirty, before morkWriter::DirtyAll() is
-called. So this design calls for writing out rows and tables when
-they are still clearly used, and additionally, <i>when we have just
-been actively writing to them right before this commit</i>.
-
-Presumably if they are truly useless, they will no longer be dirtied
-in later sessions and will get collected during the next compress
-commit. So we wait to collect them until they become all dead, and
-not just mostly dead. (At which time you can feel free to go through
-their pockets looking for loose change.)
