So we use only LockFile() and +** UnlockFile(). +** +** LockFile() prevents not just writing but also reading by other processes. +** A SHARED_LOCK is obtained by locking a single randomly-chosen +** byte out of a specific range of bytes. The lock byte is obtained at +** random so two separate readers can probably access the file at the +** same time, unless they are unlucky and choose the same lock byte. +** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range. +** There can only be one writer. A RESERVED_LOCK is obtained by locking +** a single byte of the file that is designated as the reserved lock byte. +** A PENDING_LOCK is obtained by locking a designated byte different from +** the RESERVED_LOCK byte. +** +** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available, +** which means we can use reader/writer locks. When reader/writer locks +** are used, the lock is placed on the same range of bytes that is used +** for probabilistic locking in Win95/98/ME. Hence, the locking scheme +** will support two or more Win95 readers or two or more WinNT readers. +** But a single Win95 reader will lock out all WinNT readers and a single +** WinNT reader will lock out all other Win95 readers. +** +** The following #defines specify the range of bytes used for locking. +** SHARED_SIZE is the number of bytes available in the pool from which +** a random byte is selected for a shared lock. The pool of bytes for +** shared locks begins at SHARED_FIRST. +** +** The same locking strategy and +** byte ranges are used for Unix. This leaves open the possibility of having +** clients on win95, winNT, and unix all talking to the same shared file +** and all locking correctly. To do so would require that samba (or whatever +** tool is being used for file sharing) implements locks correctly between +** windows and unix. I'm guessing that isn't likely to happen, but by +** using the same locking range we are at least open to the possibility. +** +** Locking in windows is manditory. For this reason, we cannot store +** actual data in the bytes used for locking. The pager never allocates +** the pages involved in locking therefore. SHARED_SIZE is selected so +** that all locks will fit on a single page even at the minimum page size. +** PENDING_BYTE defines the beginning of the locks.

So we use only LockFile() and -** UnlockFile(). -** -** LockFile() prevents not just writing but also reading by other processes. -** A SHARED_LOCK is obtained by locking a single randomly-chosen -** byte out of a specific range of bytes.

A RESERVED_LOCK is obtained by locking -** a single byte of the file that is designated as the reserved lock byte. -** A PENDING_LOCK is obtained by locking a designated byte different from -** the RESERVED_LOCK byte. -** -** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available, -** which means we can use reader/writer locks. When reader/writer locks -** are used, the lock is placed on the same range of bytes that is used -** for probabilistic locking in Win95/98/ME. Hence, the locking scheme -** will support two or more Win95 readers or two or more WinNT readers. -** But a single Win95 reader will lock out all WinNT readers and a single -** WinNT reader will lock out all other Win95 readers. -** -** The following #defines specify the range of bytes used for locking. -** SHARED_SIZE is the number of bytes available in the pool from which -** a random byte is selected for a shared lock. The pool of bytes for -** shared locks begins at SHARED_FIRST. -** -** The same locking strategy and -** byte ranges are used for Unix. This leaves open the possibility of having -** clients on win95, winNT, and unix all talking to the same shared file -** and all locking correctly. To do so would require that samba (or whatever -** tool is being used for file sharing) implements locks correctly between -** windows and unix. I'm guessing that isn't likely to happen, but by -** using the same locking range we are at least open to the possibility. -** -** Locking in windows is manditory. For this reason, we cannot store -** actual data in the bytes used for locking. The pager never allocates -** the pages involved in locking therefore. SHARED_SIZE is selected so -** that all locks will fit on a single page even at the minimum page size. -** PENDING_BYTE defines the beginning of the locks. By default PENDING_BYTE -** is set high so that we don't have to allocate an unused page except -** for very large databases. But one should test the page skipping logic -** by setting PENDING_BYTE low and running the entire regression suite. -** -** Changing the value of PENDING_BYTE results in a subtly incompatible -** file format.
