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 VdbeCoverage macros are used to set a coverage testing point +** for VDBE branch instructions. The coverage testing points are line +** numbers in the sqlite3.c source file. VDBE branch coverage testing +** only works with an amalagmation build. That's ok since a VDBE branch +** coverage build designed for testing the test suite only. No application +** should ever ship with VDBE branch coverage measuring turned on. ** -** 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. +** VdbeCoverage(v) // Mark the previously coded instruction +** // as a branch ** -** The same locking strategy and -** byte ranges are used for Unix. This leaves open the possiblity 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. +** VdbeCoverageIf(v, conditional) // Mark previous if conditional true ** -** 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.

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. ** -** Table.zName is the name of the table. The case of the original -** CREATE TABLE statement is stored, but case is not significant for -** comparisons. +** 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. ** -** Table.nCol is the number of columns in this table. Table.aCol is a -** pointer to an array of Column structures, one for each column. +** 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. ** -** If the table has an INTEGER PRIMARY KEY, then Table.iPKey is the index of -** the column that is that key. Otherwise Table.iPKey is negative. Note -** that the datatype of the PRIMARY KEY must be INTEGER for this field to -** be set. An INTEGER PRIMARY KEY is used as the rowid for each row of -** the table. If a table has no INTEGER PRIMARY KEY, then a random rowid -** is generated for each row of the table.

Depending on how it is changed, you might not notice +** the incompatibility right away, even running a full regression test. +** The default location of PENDING_BYTE is the first byte past the +** 1GB boundary. ** -** Table.tnum is the page number for the root BTree page of the table in the -** database file. If Table.iDb is the index of the database table backend -** in sqlite.aDb[]. 0 is for the main database and 1 is for the file that -** holds temporary tables and indices. If TF_Ephemeral is set -** then the table is stored in a file that is automatically deleted -** when the VDBE cursor to the table is closed.

Either way is valid. +# +# You'll need to run vcvars32.bat contained in the MsDev's vc(98)/bin +# directory to setup the proper environment, if needed, for your current +# setup. This is a needed bootstrap requirement and allows the swapping of +# different environments to be easier. +# +# 2) To use the Platform SDK (not expressly needed), run setenv.bat after +# vcvars32.bat according to the instructions for it. This can also turn on +# the 64-bit compiler, if your SDK has it. +# +# 3) Targets are: +# all -- Builds everything. +# -- Builds the project (eg: nmake sample) +# test -- Builds and runs the test suite. +# install -- Installs the built binaries and libraries to $(INSTALLDIR) +# in an appropriate subdirectory. +# clean/realclean/distclean -- varying levels of cleaning. +# +# 4) Macros usable on the commandline: +# INSTALLDIR= +# Sets where to install Tcl from the built binaries. +# C:\Progra~1\Tcl is assumed when not specified. +# +# OPTS=static,msvcrt,staticpkg,threads,symbols,profile,loimpact,none +# Sets special options for the core. The default is for none. +# Any combination of the above may be used (comma separated). +# 'none' will over-ride everything to nothing. +# +# static = Builds a static library of the core instead of a +# dll. The shell will be static (and large), as well. +# msvcrt = Effects the static option only to switch it from +# using libcmt(d) as the C runtime [by default] to +# msvcrt(d). This is useful for static embedding +# support. +# staticpkg = Effects the static option only to switch +# tclshXX.exe to have the dde and reg extension linked +# inside it. +# threads = Turns on full multithreading support. +# thrdalloc = Use the thread allocator (shared global free pool). +# symbols = Adds symbols for step debugging. +# profile = Adds profiling hooks. Map file is assumed. +# loimpact = Adds a flag for how NT treats the heap to keep memory +# in use, low. This is said to impact alloc performance. +# +# STATS=memdbg,compdbg,none +# Sets optional memory and bytecode compiler debugging code added +# to the core. The default is for none. Any combination of the +# above may be used (comma separated). 'none' will over-ride +# everything to nothing. +# +# memdbg = Enables the debugging memory allocator. +# compdbg = Enables byte compilation logging. +# +# MACHINE=(IX86|IA64|ALPHA) +# Set the machine type used for the compiler, linker, and +# resource compiler.
