(********************** User-Trigerred Conditionals **********************)

{  Those conditionals below can be enabled in your project Options,
   to tune the compilation depending your setup or your project expectations. }

{.$define USEPACKAGES}
// define this if you compile the unit within a Delphi package
// - it will avoid error like "[DCC Error] E2201 Need imported data reference
// ($G) to access 'VarCopyProc'"
// - shall be set at the package options level, and left untouched by default
// - note: you should probably also set "Generate DCUs only" in Project Options
// -> Delphi Compiler -> Output C/C++ -> C/C++ output file generation

{.$define PUREMORMOT2}
// if defined, no mORMot 1.18 compatilibity types nor functions would be enabled
// - by default, existing projects should (almost) compile with mORMot 2
// - you should eventually define this conditional to make a perfect code
// conversion to the new types and methods definitions

{.$define NEWRTTINOTUSED}
// if defined, the new RTTI (available since Delphi 2010) won't be linked to
// the executable: resulting file size will be much smaller, and mORMot won't
// be affected (unless you use the enhanced RTTI for record/dynamic array JSON
// serialization) - left undefined by default to ensure minimal impact

{.$define FPCUSEVERSIONINFO}
// link low-level fileinfo/machoreader/elfreader for TFileVersion/TExeVersion
// from mormot.core.os.pas => disabled by default, to preserve code size

{.$define NOSETTHREADNAME}
// if defined, SetThreadName() would not raise the exception used to set the
// thread name: to be defined if you have issues when debugging your application

{.$define NODIRECTTHREADMANAGER}
// on POSIX, omit direct GetThreadManager() API calls and just use RTL functions

{.$define NOEXCEPTIONINTERCEPT}
// if defined, exceptions shall not be intercepted nor logged

{.$define NOPATCHVMT}
// disable the vmtAutoTable slot runtime patch, replacing it with Rtti.FindType
// - is likely to be defined with the NOPATCHRTL conditional
// - could be used e.g. when in-memory executables can't be patched (e.g. on
// security constrained systems, or on OS without any mmap support)

{.$define NOPATCHRTL}
// if defined, FPC RTL won't be patched on x86_64 with optimized asm
// - is likely to be defined with the NOPATCHVMT conditional
// - you can enable it if you find out some compatibility problem

{$ifdef CPUX86}
  {.$define HASNOSSE2} // force x87 code on very very old CPU
{$endif CPUX86}

{.$define NOSYNDBZEOS}

{.$define NOSYNDBIBX}
// make mormot.db.sql.ibx.pas a "void" unit - defined for FPC/Lazarus packages only

{.$define MONGO_OLDPROTOCOL}
// may be used with old MongoDB instances < 3.6 with no OP_MSG in Wire protocol

{.$define DISABLEAPPSQL}
// mormot.db.sql external DB won't be linked to the executable by mormot.app

{.$define DISABLEAPPNOSQL}
// Mongo DB client won't be linked to the executable by mormot.app

{.$define NOSSPIAUTH}
// disable Windows mormot.lib.sspi support in mormot.rest.client/server units

{.$define NOGSSAPIAUTH}
// disable Posix mormot.lib.gsssapi support in mormot.rest.client/server units

{.$define NOPOINTEROFFSET}
// disable TOrmTable offsets on 64-bit if your memory is huge or fragmented
// note: FPCMM_MEDIUM32BIT may need this for data >256KB

{.$define NOTORMTABLELEN}
// disable TOrmTable internal fLen[] pre-computed table - slower but less memory

{.$define NOSQLITE3STATIC}
// disable static SQlite3 linking - to force use external dll/so library

{.$define NOSQLITE3FPUSAVE}
// disable SetFpuFlags() calls during SQlite3 engine - may enhance performance

{.$define DEBUGSTORAGELOCK}
// could be defined to force verbose log of StorageLock/StorageUnLock

{.$define DEBUGSQLVIRTUALTABLE}
// could be defined to force verbose log of SQlite3 virtual table query planner costs

{.$define ONLYUSEHTTPSOCKET}
// is defined on POSIX but may be enabled on Windows if socket+SChannel is enough

{.$define OLDLIBC}
// use only oldest libc API, e.g. accept() instead of accept4()

{.$define OLDLINUXKERNEL}
// use only oldest Linux syscalls - as in FPC RTL

{.$define USE_OPENSSL}
// is defined on POSIX (with late binding) but may be enabled on Windows too

{.$define USELIBCURL}
// define cross-platform libcurl for https
// (when our native socket+OpenSSL/SChannel doesn't seem to be good enough)

{.$define LIBCURLMULTI}
// enable the more advanced "multi session" API functions of mormot.lib.curl
// see https://curl.haxx.se/libcurl/c/libcurl-multi.html interface
