**
** The dotfile locking implementation uses the existance of separate lock
** files in order to control access to the database. This works on just
** about every filesystem imaginable. But there are serious downsides:
**
** (1) There is zero concurrency. A single reader blocks all other
** connections from reading or writing the database.
**
** (2) An application crash or power loss can leave stale lock files
** sitting around that need to be cleared manually.
**
** Nevertheless, a dotlock is an appropriate locking mode for use if no
** other locking strategy is available.
**
** Dotfile locking works by creating a file in the same directory as the
** database and with the same name but with a ".lock" extension added.
** The existance of a lock file implies an EXCLUSIVE lock. All other lock
** types (SHARED, RESERVED, PENDING) are mapped into EXCLUSIVE.

************************* Begin dot-file Locking ******************************
**
** The dotfile locking implementation uses the existance of separate lock
** files (really a directory) to control access to the database. This works
** on just about every filesystem imaginable. But there are serious downsides:
**
** (1) There is zero concurrency. A single reader blocks all other
** connections from reading or writing the database.
**
** (2) An application crash or power loss can leave stale lock files
** sitting around that need to be cleared manually.
**
** Nevertheless, a dotlock is an appropriate locking mode for use if no
** other locking strategy is available.
**
** Dotfile locking works by creating a subdirectory in the same directory as
** the database and with the same name but with a ".lock" extension added.
** The existance of a lock directory implies an EXCLUSIVE lock. All other
** lock types (SHARED, RESERVED, PENDING) are mapped into EXCLUSIVE.

Those wrappers ** are designed for use on embedded systems where memory is scarce and ** malloc failures happen frequently. Win32 does not typically run on ** embedded systems, and when it does the developers normally have bigger ** problems to worry about than running out of memory. So there is not ** a compelling need to use the wrappers. ** ** But there is a good reason to not use the wrappers. If we use the ** wrappers then we will get simulated malloc() failures within this ** driver. And that causes all kinds of problems for our tests. We ** could enhance SQLite to deal with simulated malloc failures within ** the OS driver, but the code to deal with those failure would not ** be exercised on Linux (which does not need to malloc() in the driver) ** and so we would have difficulty writing coverage tests for that ** code. Better to leave the code out, we think. ** ** The point of this discussion is as follows: When creating a new ** OS layer for an embedded system, if you use this file as an example, ** avoid the use of malloc()/free().
