* return value of GetLastOSError if one is available, to be consistent with handle-based implementations and Delphi behavior.
* otherwise, return -1
git-svn-id: trunk@16318 -
* added function ExcludeLeadingPathDelimiter: it removes a path delimiter in front of a path
* added function ConcatPaths: it concats multiple path fragments, path delimiters are added if necessary
git-svn-id: trunk@15167 -
significant digits before the decimal points matches the precision
parameter exactly (mantis #16188)
* round instead of cut off digits in FloatToStr with ffGeneral
* take into account the minus sign when determining whether a number needs
to be represented using ffExponent instead of ffGeneral because it has
too many digits
git-svn-id: trunk@15114 -
* GetInterface and GetInterfaceWeak is modified so that when querying for IObjectReference not an interface is returned but the object pointer
git-svn-id: trunk@15087 -
atomic operations so that in case it's created while multiple threads are
already running, all threads are guaranteed to see this initialisation
* some minor changes to the comments of TMREWS
git-svn-id: trunk@15074 -
so the TMultiReadExclusiveWriteSynchronizer routines can be safely
executed even with the default thread manager -> removed ismultithread
checks, so that it keeps working even if ismultithread is set to true
between acquiring and freeing a lock (mantis #15619)
git-svn-id: trunk@14830 -
TMultiReadExclusiveWriteSynchronizer, to ensure that out-of-order
execution cannot already perform some reads inside the critical section
before the lock has been acquired
- removed now unnecessary read barrier before releasing a read lock
git-svn-id: trunk@14820 -
critical section, so that it can be entered recursively just like
the one from TSimpleRWSync + test
- reverted r14593, since the reason for using TRWSync instead of
TMultiReadExclusiveWriteSynchronizer was because the former
supported recursive write locks
git-svn-id: trunk@14594 -
(to remove warnings)
* don't give a thread error for basicevent and threadevent routines if
isMultiThreaded is false, except for the waiting routines (the new
TMultiReadExclusiveWriteSynchronizer creates/sets such events in the
constructor, which caused thread manager errors in case cthreads was
not used under unix)
* don't perform any actual locking in TMultiReadExclusiveWriteSynchronizer
routines if isMultiThreaded is false (in order to avoid the errors
described above)
+ added generic RTLeventResetEvent stub
git-svn-id: trunk@14592 -
- Adds threadsafe (Delphi-compatible) versions of DateToStr,
TimeToStr, DateTimeToStr, FormatDateTime.
- Core functionality moved to DateTimeToString, which directly
uses 'out' parameter in order to avoid unnecessary result copying.
- Modified the code so no temporary AnsiStrings are used (speed).
- Fixes a bug which would cause infinite recursion if
(Short|Long)DateFormat variable would contain 'd' character or,
likewise, (Short|Long)TimeFormat would contain 't'.
- Fixes numerous small Delphi compatibility issues, like: empty format
string has the same effect as 'C'; overlong tokens treated as the
longest possible ones (e.g. 'ddddddddd' is the same as 'dddddd');
'AM/PM' is output preserving its case, etc.
- minor reformating
