Qore 1.0.9
- Release Summary
- Bugfix release; see below for more information
Bug Fixes in Qore
- fixed stack size reporting for the initial thread on Linux; Linux autoextends the initial thread in any case, so a large stack size is reported (8MB) regardless of the actual stack size reported by pthreads APIs; this allows code that requires a larger stack to run normally on Linux platforms that allocate a small initial stack (such as Alpine, for example, current versions allocate a 128KiB stack which caused stack exceptions in Qore or recursion exceptions in Python to be thrown in the main thread with code that would otherwise work on Linux) (issue 4325)
Qore 1.0.8
- Release Summary
- Bugfix release; see below for more information
Bug Fixes in Qore

Fixes That Can Affect Backwards-Compatibility
- The ConnectionProvider module was updated with support for verbose option reporting and a connection cache; support for the deprecated constructor was removed from
HttpConnection, HttpBasedConnection, as well as from other connection classes
- The mkdir() function was modified to provide consistent behavior and a consistent return value with and without the parents argument; this function never throws an exception now, and always returns either
0 (meaning no error occurred) or 1 (meaning an error occurred) and no longer returns the number of directories created when parents = True. Use Dir::create() to get the number of directories created as in previous versions of Qore; - See also
- Qore::mkdir_ex()
- Fixed broken range() and xrange() where the upper limit of the range was included in the result for maximum compatibility with other languages. To get the old behavior, use the %broken-range parse directive.
- Floating-point values are always converted to strings with a decimal point; in previous releases of Qore, round floating-point values were converted to strings without any decimal point; i.e.
1.0 will now be converted to "1.0" (in previous releases of Qore, it would be converted to simply "1")

Fixes That Can Affect Backwards-Compatibility
- RestHandler module: renamed
RestHandler::getPossibleSubClasses() to RestHandler::doGetPossibleSubClasses() in order to avoid a collision with a REST method name (issue 3614)

Qore 0.9
- Release Summary
- This is a major release of Qore with large portions of code subject to extensive optimizations leading to large memory and performance improvements along with more control of Program logic containers, multithreading, and a reflection API. This release breaks binary compatibility with older versions of Qore as well, requiring binary modules to support the new API and ABI.
Changes That Can Affect Backwards-Compatibility
- Qore classes and functions are now immutable once created; any attempt to add a new user variant to an existing function or method or to add new declarations to an existing class will result in a parse error.
- Program objects now only support a single complete parse action (Program::parse() or Program::parseCommit()); subsequent attempts to parse code into the same Program object will fail with an exception. If parsing fails due to a parse exception, the Program object is generally no longer usable and must be recreated to be used.
- Program::parseRollback() is now deprecated; this action removes all user code and most builtin code from the Program object; delete the object instead of using this method
- the transient keyword has been introduced to support control over object serialization; see also %no-transient
New Features in Qore
- Up to 70% reduced memory usage in Qore programs through:
- Extensive memory optimizations
- Changing the default thread stack size from 8 MB to 512 KB (issue 2701)
- Eliminating heap-allocated, atomic-reference-counted integer and floating-point values resulted in reduced memory usage as well as faster runtime execution
- Reflection API
- Data and object serialization support:
- All data types except closures, call references, references, and non-serializable objects can be serializeed
- All objects from classes inheriting Serializable can be serialized
- Class members declared with the transient keyword (new in this release) will not be serialized but instead will get their default values when deserialized
- Classes can define their own local serialization and deserialization logic by defining the serializeMembers() and deserializeMembers() methods, respectively
- The following builtin classes support serialization:
- New classes:
- AbstractSQLStatement: has been added as the parent class defining an abstract API for SQLStatement
- Serializable: a new class supporting data and object serialization
- StreamBase: a base class for stream classes allowing for a controlled handoff of a stream to another thread
- Added support for importing a split user module represented as directory (issue 2562)
- New and updated methods in existing classes:
- New functions:
- Updated functions:
- New modules:

Qore 0.8.13
- Release Summary
- Major new features and bug fixes including input and output stream support and sigificant new functionality including several new modules.
Changes That Can Affect Backwards-Compatibility
- fixed broken continue and break statements that were accepted anywhere in the source and behaved like a return statement; now such statements outside a loop context will result in a parse exception; to get the old behavior, use %broken-loop-statement in your source code
- fixed broken reference and *reference type restrictions which had no effect prior to this release; to get the old behavior, use %broken-references in your source code
- the random number generator is always seeded with a random number when the Qore library is initialized; to get a predictable sequence from rand(), you must explicitly seed the random number generator by calling srand() with a predefined seed number
- the synchronized keyword now operates differently depending on the context;
synchronized functions have a global reentrant lock associated with the function (as in previous versions of Qore), whereas now synchronized normal class methods share a reentrant lock associated with the object, while synchronized static class methods share a reentrant lock associated with the class itself. This aligns Qore's synchronized behavior with that of Java and [MethodImpl(MethodImplOptions.Synchronized)] .NET/CLR (issue 894).
- classes may not have the name
"auto" due to the introduction of this identifier as a special type name
- a new keyword hashdecl has been introduced to support type-safe hash declarations
New Features in Qore
- complex type support
- type safe hashes (Type-Safe Hash Type); ex:
hash<MyInfo> = get_info();
- new system types:
- hash with type-safe values; ex:
hash<string, int> h = ("str": 1);
- list with type-safe values; ex:
- reference with type-safe lvalues; ex:
int i = 1; reference<int> r = \i;
- auto (allows any value including complex types to be assigned without losing complex type information); ex:
- improved new, cast<>, and instanceof operators
- the instanceof operator now works with any type; ex:
bool b = v instanceof hash<string, int>;
- note that complex type information is lost when assigning to an lvalue with a compatible but more generic type or by assigning to an untyped lvalue; this was necessary to allow complex types to be introduced in Qore without breaking backwards compatibility.
- support for input and output streams for the efficient piecewise processing of small or large amounts of data with a low memory overhead
- includes the following classes:
- Three constants were introduced for accessing standard input/output using streams API:

Bug Fixes in Qore
Qore 0.8.12
- Release Summary
- Major new release with major new features and bug fixes as well as packaging fixes:
- added support for deterministic garbage collection
- standardized function naming convention
- new functions, methods, constants, operators, and user modules
- greatly improved support on Windows
Changes That Can Affect Backwards-Compatibility
- fixed broken list parsing; in previous releases, Qore's parser re-wrote lists without parentheses used as top-level statements with certain assignment operators (=, +=, -=, *=, and /=, but not with others) so that statements like
list l = 1, 2, 3; were valid assignments. Due to operator precedence, such statements should normally be interpreted as (list l = 1), 2, 3;, which is not a valid expression. Not only were the rules applied with only some assignment operators, but such lists were only rewritten if used as top-level statements, therefore the rules were applied inconsistenctly depending on where the expression was located in the parse tree. As of Qore 0.8.12, these inconsistencies have been eliminated by default from Qore; all lists are processed according to the precedence rules defined in Operators. This could break old code that relied on the old, broken behavior. To get the old behavior, use the %broken-list-parsing parse directive.
- fixed broken int and softint assignments; previously runtime type errors with these type restrictions were ignored and all values were silently converted to integers for the assignment, now runtime type errors are thrown according to the original design. Parse errors are detected as before. This could break old code that relied on the old, broken behavior. To get the old behavior, use the %broken-int-assignments parse directive.
- fixed broken multi-character operator parsing; the Qore parser has been updated to no longer accept multi-character operators with whitespace between the chacters making up the operator; it is believed that this was never used and simply caused the parser to be needlessly complicated and caused Qore to be less compatible with other languages. To get the old behavior, use the %broken-operators parse directive.
- the push, unshift, pop and shift operators now throw an exception when their first operand is not a list and %strict-args is in effect
New Features in Qore
- Added the Value Coalescing Operator (?*) which checks first argument if it evaluates to False with <value>::val() and if so assigns the second argument. The operator can be further chained; for example:
- Added the Null Coalescing Operator (??) which checks the first operand for NOTHING or NULL; if true returns the second argument. The operator can be further chained, in which case the first operand with a value is returned; ex:
- Qore identifiers can now begin with an underscore character
"_"; the following is now a valid (with %new-style):
- hash enhancements:
- new syntax for an expression giving an empty hash:
{}; for example:
- new literal hash support: hashes can now be given as literal values as follows:
(<key_expr>: <val_expr>, [...])
return (get_key(): get_value());
- new hash syntax; hash elements can now be enclosed by curly brackets as well as regular parentheses; the version with curly brackets when used with the map operator results in the hash version of the map operator being used
- Added new hash version of the map operator to build a hash from a list or iterator expression; ex:
hash h = map {$1, h2.$1}, i;
- implemented support for loading user modules in a pre-defined Program object (that can have a custom API) in the following new functions and methods:
- implemented support for code / dependency injections in Program containers with the following changes:
- Qore::Program::importClass() now accepts optional arguments that allow the imported version of the class to live in another namespace and have another name and an argument that allows the imported version of the class to remain even if it overlaps with an imported system or user class from a module
- Qore::Program::importFunction() now accepts an optional argument that allows the imported version of the function to remain even if it overlaps with an imported system or user function from a module
- the new parse option Qore::PO_ALLOW_INJECTION must be set on the Program object in order to use code / dependency injection parameters in the above methods
- Program changes:
- Once the object has an injected API set up, the system API can be imported (possibly already overridden with injected code) with the following new methods:
- Additionally user modules can be loaded with overridden injected code with the following new functions / methods:
- Furthermore the following function can be used to reload injected modules with the non-injected version:
- implemented support for user-defined thread-resource management, allowing Qore code to safely manage resources associated to a particular thread:
- new constants:
- new classes:
- other new methods:
- updated methods:

- removed support for the C++
QDBI_METHOD_ABORT_TRANSACTION_START DBI method; transactions are always assumed to be in progress even if an exec call throws an exception in the first statement in a new transaction; this is necessary to handle bulk DML where a single statement can partially succeed and partially fail; the ABI remains unchanged; drivers that set this DBI method will no longer have it called because it's not necessary; in the upcoming API/ABI change this C++ DBI method will be removed entirely

- fixed format of octal constant - there was an error if a string contained octal constant that is shorter than 3 digit
- HttpServer module fixes:
- fixed a bug setting the response encoding in HttpServer::setReplyHeaders() where the Socket encoding was not set properly and therefore the encoding in the Content-Type in the response header did not necessarily match the encoding of the response
- fixed a socket / connection performance problem with HTTPS listeners where the SSL connection was being negotiated inline with the accept instead of in the connection thread, thereby blocking new connections from being accepted
- fixed bugs where URI strings were improperly encoded and decoded (also fixed in the RestClient module)
- fixed a bug in the HttpServer module where chunked sends were not received and decoded properly in all cases for handlers that did not explicitly handle chunked messages
- fixed a bug in HttpServer::addListener() with an integer argument; a UNIX socket was opened instead of a wildcard listener on the given port
- fixed typos causing bugs in HTTP error logging (issue 308)
- fixed a bug formatting IPv6 host addresses in the return value to
HttpServer::http_get_url_from_bind() (issue 821)

- Schema module fixes:
- AbstractSchema::combineOptions() fails when an option variable contains NOTHING instead of a valid hash
- fixed a bug with "insert-only reference data" with the verbose option; the upsert strategy was changed to

- fixed a bug in the ThreadPool class where an error in shutdown handling could cause a crash in rare conditions when ThreadPool methods are called while the pool is shutting down
- fixed a crashing bug initializing some lvalues with type restrictions; affected static class variables at least
- fixed a bug where a class calling an overridden method in a base class constructor that referred to a member that should have been initialized in the subclass would be executed before the subclass's members were initialized causing the method call to fail
- fixed a memory leak in classes with multiple inheritance and base classes that are inherited multiple times with member initialization
- fixed a bug in the %include and %append-module-path parse directives where relative paths were not calculated from the script's directory but instead were calculated from the current working directory, causing such paths to fail

- fixed a bug in the Qore::FtpClient class where connection problems in the data channel when executing certain FTP commands could cause a crash due to missing error checking
- fixed a bug in Qore's internal strcasestr() function on platforms that do not support this function (ex: Solaris) that could result in a crash
- fixed a bug in Qore where string data formatted with
%n, %N, or %y could be added to another string with a different character encoding without any automatic conversions, therefore resulting in an improperly-encoded string
- fixed a crash when parsing when parsing function, method, or closure arguments when either of the duplicate-local-vars or duplicate-block-vars warnings are set due to an error handling thread-local variable info in parse initialization

Content-Encoding header would cause a crash
- fixed a memory error with receiving HTTP chunked data with receive callbacks where the buffer object was reset with reference counts > 1

737.38.toNumber() -> 737.3799999999999954525264911353588104248
- fixed a bug where %requires would fail loading a user module inside a %try-module block
- fixed a bug in Qore::Program::importClass() where the import would fail if a namespace-justified class name was given and any element of the namespace path didn't already exist in the target whereas the same import would succeed if the namespace were omitted in the call
- fixed bugs in Qore::Program::importClass(), Qore::Program::importFunction(), and Qore::Program::importGlobalVariable() when namespace-justified arguments were given, in this case when namespaces were created in the target, the internal root namespace index was not updated so the imported objects could not be found with namespace-justified references until the root indexes were updated
- fixed a bug in the %requires directive where relative paths were not calculated from the script's directory but rather from the current working directory
- fixed various bugs in path handling on Windows in the following areas:
- fixed a bug in parsing constant value assignment expressions where such expressions could use or instantiate classes with uncommitted changes and therefore a crash could result
- fixed a bug in user module initialization and destruction where call references were not accepted, contrary to the documentation and design goals
- fixed a bug in Qore::Socket::acceptSSL() and Qore::Socket::connectSSL() where the timeout argument was not respected for SSL protocol negotation by implementing non-blocking I/O support for the internal SSL calls for upgrading the socket connection
- fixed a memory leak in exception handling in the Qore::FtpClient::put() method (thanks to nros)
- fixed a memory error in string handling in the Qore::FtpClient class's FTP response handling code
- fixed a bug in aligning table data in the sqlutil example program
- fixed a bug when loading modules by a path argument; if the module is already loaded, then do not throw an exception
- adjusted the stack guard buffer for x86_64 from 20K -> 32K which solved some rare crashes related to stack exhaustion (ex: make check works consistently now on x86_64 Linux)
- fixed a bug handling HTTP send callbacks that returned zero-length strings and binary objects which would cause invalid chunked data to be sent violating the HTTP protocol
- fixed a bug in the DatasourcePool::getServerVersion() method where the connection to the server was not guaranteed to be in place before the call, in case of connection errors in the pool a crash could result
- fixed a crash in Qore::FileLineIterator::copy() when no eol attribute is set
- fixed a bug importing invalid user modules with no module declaration
- fixed bugs in Qore::Socket::accept() and Qore::Socket::acceptSSL() where the SSL configuration was not copied to the new Qore::Socket
- fixed some object encapsulation violation bugs where access to methods of a privately-inherited class was allowed from a subclass in certain situations
- fixed inconsistent object encapsulation enforcement with method references; if a reference to a method is created inside the class, then when executed the call inherits the access rights at the time of creation
- fixed inconsistent thread gating for code data structures in Program containers that could have theoretically lead to crashes in Program containers that parse code while threads are running
- fixed a bug in Qore::Program::importFunction() with function names with a namespace path
- fixed a bug in closure calls when a closure is called from within a closure and referes to closure-bound locally variables in the internal closure call which would previously result in a crash
- fixed a parse-time memory leak in call reference calls when the callable object is resolved from a class constant
- fixed a bug in maintaining the conditional compilation status when parsing %include directives and %requires directives with user modules
- fixed an obscure bug when a thread terminates in a Program object after the Program container itself has already been deleted where the termination would hang while waiting for the Program's thread count to reach zero while the last thread doing the waiting also held the last thread reference
- fixed a bug where incompatible class definitions were not verified at parse time which could cause a crash in debug builds and unpredictable behavior in non-debug builds
- fixed a race condition in finalizing thread-local data in Program objects during Program destruction that could lead to a runtime crash
- fixed a crash when user modules have recursive dependencies
- fixed a bug with %push-parse-options when used multiple times in the same file; now multiple appearances of this parse directive are ignored
- fixed a bug initializing static class variables in the parse commit phase where a crash could result due to an error in managing parse commit dependencies
- fixed Qore::is_writable():
- on Windows when used with a directory
- on UNIX to return a value for the current permissions the program is running under
- fixed a bug in Qore::regex_extract() and in the Regular Expression Pattern Extraction Operator where the result buffer was not resized when it was too small, limiting regular expressions to nine subpatterns; the maximum has been raised to between 90 and 100 before an exception is raised (since the subpattern buffer is allocated on the stack, we need to enforce a limit)
- fixed a bug with the cast<>() operator where compatible classes were not recognized at runtime that would otherwise be recognized correctly without the cast
- fixed the return type in Qore::getcwd() to *string
- fixed a bug in the return statement where the runtime return type was used at parse time which did not work when parsing embedded code
- fixed a bug validating return values in method evaluation that could lead to a qore crash
- fixed a bug in the %requires directive when applied to builtin features where code to manage user module dependencies was inappropriately applied
- fixed a bug nesting 3 levels or more of parse conditionals (%ifdef and %ifndef) where the conditional parse state could be lost (and an assertion was made in debug mode)

- fixed a static memory leak in the parser handling out of line method declarations
- fixed a bug in handling socket disconnection errors in SSL operations where the SSL helper object was deleted and then used causing a crash
- fixed a bug where Deprecated List and return-value-ignored warnings were reported at the incorrect source location
- fixed a bug in Qore::set_thread_init() where thread initialization did not occur when foreign threads attached to a Qore::Program object with thread initialization set
- fixed a bug in call references and objects by replacing string references to the containing Program object with weak references which solved a recursive reference / memory leak issue
- fixed a memory leak when a thread init call reference was used with Qore::Program objects
- fixed bugs in Qore SSL socket handling when the remote connection is disconnected while performing an SSL upgrade (client or server) that could cause a crash
- fixed a bug where the sending an invalid HTTP header to the Qore::Socket::sendHTTPResponse() method could cause a crash
- fixed bugs in system():
- the shell was not being used to execute commands with commands where shell meta-characters were not found with a manual search which caused such commands to fail; additionally
& (ampersand) characters were not recognized as shell meta-characters
- fixed problems with signal handling in child processes on UNIXes: system() now always performs a
fork(2), enables all signals, and calls execl("/bin/sh", "sh", "-c", command, 0) in the child process (on UNIX systems; on Windows, system(3) is used directly as before)
- fixed a race condition in the DatasourcePool class when opening new datasources after a connection error in the first datasource which could cause a crash. Now the first datasource is no longer a "special" datasource used for configuration information; configuration information is contained in a separate object which serves as an internal Datasource factory
- fixed a problem where
SIGCHLD was blocked by default which caused deadlocks when spawning child processes that in turn waited on grandchild processes - now Qore no longer blocks SIGCHLD on UNIX platforms
- fixed a bug in BinaryNode::clear() where the internal pointer was freed but not set to 0 leading to a subsequent crash when the object is destroyed; affected HTTPClient chunked reads of binary data when used with a callback
- fixed a bug where the runtime exception location could be reported in the wrong location
- fixed a bug where the bzip2 library can request a buffer size that could not be handled by the bzip2 library which is not handled by qore and causes a crash while decompressing certain input
- fixed a bug handling closure-bound local variables when closures are created in the background operator expression that caused a core dump
- fixed the precedence of the assignment operator (=); now the precedence of this operator is the same as the other assignment operators (+=, -=, *=, and /=, etc); this does not break any code, but does align Qore with other programming languages (such as C, among others) and allows for expressions such as to be correctly parsed
- fixed a parse-time bug in the trim operator where the operator's return type was incorrectly returned as int instead of the type of the lvalue
- fixed a bug initializing object members with a closure that refers to self
- fixed bugs in the documentation and return types of:
- fixed a bug in Qore::GetOpt::parse(softlist<auto>), Qore::GetOpt::parse2(softlist<auto>), and Qore::GetOpt::parse3(softlist<auto>) where call-by-value and copy-on-write semantics were not enforced and a shared list argument could be modified
- fixed a bug in zoneinfo file parsing where invalid bands with no UTC offset changes against the previous band could cause invalid date/time values to be displayed by Qore for dates on the invalid transition
- fixed a bug where imported global variables (Qore::Program::importGlobalVariable()) were added to the pending global variable list and therefore were removed if a parse exception occurred, hwoever the namespace indexes remained, which could lead to unexpected problems at runtime including a crash. Additionally the pending global variable list was not checked which could lead to a memory leak if the a single global variable name is pending, imported, and then committed to the Program object.
- fixed memory errors managing program feature lists in the CharPtrList class by copying string memory instead of using sometimes temporary values in the list
- fixed minor bugs with directive parsing, mostly related to error reporting
- fixed bugs in relative date arithmetic where operands were swapped with the - operator if the first operand was a relative date/time value, additionally an operation with the - operator where the first operand is a relative date and the second operand is a absolute date is now calculated using the absolute date's epoch offset (offset in seconds and microseconds from
1970-01-01Z), and a relative date/time value is produced
- fixed a bug normalizing the result of date arithmetic between hour and minute components of relative date/time value
- fixed a bug where time components of absolute date/time values before the UNIX epoch were returned with invalid values
- fixed a bug where the %exec-class directive did not check for classes with unimplemented abstract variants

- fixed a bug where calls to Qore::HTTPClient::setConnectTimeout() had no effect (issue 323)
- fixed several bugs with logical comparison operators and arbitrary-precision numeric values (issue 330)
- fixed a bug where Qore::HashListIterator (and therefore <hash>::contextIterator()) would not iterate a simple hash with non-list values once but would instead silently ignore the hash (issue 336)
- fixed a bug where a warning was not always issued when square brackets were used on unsuitable types (issue 184), internally ported the square bracket operator to the C++ QoreOperatorNode hierarchy
- fixed a bug handling return type information for method and pseudo-method calls; uninitialized memory could be used which could cause a runtime crash (issue 364)
- corrected the name of the modulo operator (was incorrectly referred to as the "modula" operator earlier: issue 389)
- fixed a bug handling identifiers in parentheses used to dereference hashes or objects; the identifer is not resolved properly whereas previoulsy it was incorrectly interpreted as a string literal (issue 416)
- fixed a bug with handling local variables in const initializers (issue 421)
- fixed a bug where
select(2) was called after EINTR without reinitializing the descriptor array argument (issue 435)
- fixed a crashing bug on all platforms where select(2) was being called with socket descriptor values >
FD_SETSIZE (issue 436)
- fixed inconsistencies comparing relative date/time values (issue 437)
- fixed a bug where on_exit Statements and on_error Statements statements were not being executed if an exception was raised in an earlier-executed on_exit Statements, on_error Statements, or on_success Statements statement (issue 380)
- fixed a bug where Qore::HTTPClient::get() and Qore::HTTPClient::post() would try to retrieve a message body even if
Content-Length: 0 was returned (or if no Content-Length header was returned at all) which would result in a deadlock until the server would close the connection (issue 434)
- fixed a bug where regular expression substitution would go into an infinite loop when used with an empty pattern and the global flag (Qore::RE_Global, issue 329)
- fixed a bug with connection handling in the SQLStatement class; an exception is now thrown if a SQLStatement object tries to execute its prepared SQL on a connection other than the original connection used to prepare the statement (issue 465)
- fixed a bug where Qore::is_executable() would return NOTHING instead of False (as per documentation) when called with non-existent path as it's parameter (issue 470)
- fixed precedence of logical and bitwise Operators (issue 481)
- fixed a bug where nested lists were not parsed correctly in some cases (issue 320)
- fixed a bug where the type of catch parameter was ignored (issue 28)
- fixed a bug where namespace hierarchies were not indexed during parse time when added to already-committed namespaces which lead to symbol resolution errors for valid code (issue 538)
- fixed a bug where a Socket operation attempted in another thread while a callback operation on the same socket was in progress would result in a confusing error message (issue 530)
- fixed a bug where local variable declarations in class member initialization expressions caused a crash (issue 574)
- fixed a bug where HTTP data in HTTP socket events was modified even though it was shared which caused data consistency problems and crashes in the worst case (issue 576)
- fixed a bug where the `+=` operator handled NOTHING values incorrectly (issue 582)
- fixed a bug where a non-numeric define specified on the command line could cause a crash (issue 583)

- fixed bugs in Qore::ReadOnlyFile::readTextFile() and Qore::ReadOnlyFile::readBinaryFile() would return NOTHING instead of an empty object when reading empty files; now empty objects are returned in these cases (issue 508)
- fixed a bug in *printf() outputs on Windows with scientific notation with floating-point values (issue 621)
- fixed a bug where the precision of numbers during arithmetic operations was not adjusted correctly (issue 630, issue 908)
- fixed a bug where the type of subtraction of two numbers was inferred as NOTHING during parsing (issue 636)
- fixed a bug on Windows with Qore::Dir::create() (issue 643)
- fixed a bug where CRLF line endings were not handled correctly by the exec-class parse directive (issue 653)

RUNTIME-TYPE-ERROR exception (issue 683)
- fixed bugs reporting the current method context with certain HTTPClient methods that would report the Socket class instead (issue 689)
- fixed a bug handling aborted HTTP chunked transfers; now any data available for reading on a socket when a chunked transfer is aborted is read instead of having a
SOCKET-SEND-ERROR thrown when the remote end closes the socket during the transfer (issue 691)

- Release Summary
- Minor bugfix release for UNIX, major bugfixes for Windows
New Features in Qore
Bug Fixes in Qore
- Windows fixes:
- fixed TimeZone copying to use the standard name instead of the display name so that the info can be found in the registry
- Util module fixes:
- fixed get_random_string() on Windows
- fixed absolute_path_windows()
- HttpServer module fixes:
- when binding a wildcard address with AF_UNSPEC on Windows with HttpServer::addListeners() and both IPv6 and IPv4 addresses are returned, bind both addresses since Windows doesn't direct the IPv4 requests to the wildcard-bound IPv6 listener
- fixed file reading by always opening in binary mode
- added support for the WSAECONNABORTED socket error
- replaced Mime::MultiPartMessage::getRandomString() with Util::get_random_string() to make it work on Windows

- other fixes in the Util module (in addition to the Windows-specific fixes above):
- fixed
parse_to_qore_value() with hashes with a comma in the first key name
- read from /dev/urandom instead of /dev/random since reads from the latter can block for long periods to fill the entropy pool

Changes That Can Affect Backwards-Compatibility
- Fixed method resolution order; it's now possible to call pseudo-methods directly on classes that implement methodGate() methods
- Added the following abstract methods to AbstractDatasource:
- "hard" string comparisons now perform encoding conversions if necessary (however as usual different data types cause the comparison to fail)
New Features in Qore
- new user modules delivered with Qore:
- RestClient: Provides a simple API for communicating with HTTP servers implementing REST services
- RestHandler: Provides an easy to use interface to the Qore HttpServer module for implementing server-side REST services
- SqlUtil: Provides a high-level DB-independent API for working with database objects
- MysqlSqlUtil: Provides a high-level DB-independent API for working with MySQL database objects; loaded automatically by the SqlUtil module when working with MySQL databases
- OracleSqlUtil: Provides a high-level DB-independent API for working with Oracle database objects; loaded automatically by the SqlUtil module when working with Oracle databases
- PgsqlSqlUtil: Provides a high-level DB-independent API for working with PostgreSQL database objects; loaded automatically by the SqlUtil module when working with PostgreSQL databases
- Util: Provides a some miscellaneous generally useful routines

- improvements in existing user modules:
- much improved HttpServer module, better performance, much better RFC compliance, more flexibility
- new CSV generation class in CsvUtil
- much better message serialization and email attachment handling in the SmtpClient and MailMessage modules
- there is a new ThreadPool class for implementing thread pools that automatically upscale and downscale within user-defined limits depending on the load placed on them
- it's possible to inherit concrete versions of abstract method variants from a parent class that does not define the abstract method, meaning that concrete variants of an abstract method do not have to be implemented in a direct subclass of the class declaring the abstract method
this makes using abstract base classes much easier in complex hierarchies using multiple inheritance; now common code can be separated into a single class and inherited by child classes sharing the common implementation
- major Socket read performance increase by implementing internal read buffering (up to 10x faster socket read performance for certain operations, particularly with HTTP methods)
- improved Unicode / UTF-8 support
- new Datasource and DatasourcePool methods:
- HTTPClient changes:
- new functions:
- new pseudo methods:
- other new methods and method changes:
- function changes
- added optional start and end parameters to the replace() function
- all data type declarations that optionally accept NOTHING also now accept NULL and map NULL to NOTHING; this makes direct assignments from values derived from SQL queries much easier
- added an optional reference to an integer to the Qore::backquote() function to return the return code of the program executed
- implicit index references now work in the map and select operators with lists and iterators
- the Regular Expression Pattern Extraction Operator now accepts an optional
g specifier to extract all occurrences of the pattern(s) in a string; also regex_extract() and <string>::regexExtract(string, int) now accept Qore::RE_Global to extract all occurrences of the pattern(s) in a string
- the splice and extract operators were extended to work on binary objects as well as lists and strings
- printing out binary values with the
"%y" format specifier now produces YAML-like output for the binary value
- added path name to error messages in Dir class exception strings
Bug Fixes in Qore
- fixed a bug where the ?: operator could thrown spurious exceptions when parsing because it would return the type of the initial boolean expression as the return type of the operator
- fixed a bug where classes with unimplemented inherited abstract variants would sometimes cause runtime exceptions to be thrown when instantiated but should have instead been caught at parse time
- fixed a parser bug where out-of-line class method definitions could not be defined in a namespace block
- fixed a bug parsing arguments in parse_uri_query() in the HttpServer module
- fixed several bugs where parse exceptions could show the wrong source location:
- with type errors in function calls
- when resolving global variables
- in base class constructor arguments
- for empty blocks with a missing return statement
- when validating types used with the return statement (also associated warnings)
- in methods calls
- in hash value expressions
- with redeclaring local variable return types
- in local variable object instantiations
- really fixed the bug thought to be fixed in 0.8.7 "where SSL errors would cause the affected thread to go into a infinite loop using 100% CPU" - this turned out to be easily reproducible on all platforms; when the SSL connection was shut down cleanly by the remote end before a response message was returned, an infinite loop would result
- fixed a bug where it was impossible to output a single '\' character in regex substitution expressions; '\' was taken as an escape character, and '\\' was output literally, now '\\' is output as '\'
- fixed a bug where a parse-time crash would occur when calling the copy() method for a class that does not implement an explicit copy() method
- fixed a bug where arguments passed to a copy method were ignored; now an exception is thrown
- fixed a bug where public members and static variables of privately-inherited classes were incorrectly treated as public attributes of the child class
- fixed a bug where slices could be made of objects from outside the class including private members
- fixed a bug where memberGate() methods were not being respected when taking a slice of an object
- fixed bugs in the integer Socket::recv*() methods where a
SOCKET-CLOSED exception was not thrown when the remote end closed the connection
- fixed a bug related to out-of-order parse initialization for functions and methods which resulted in the wrong return type being returned for a method with more than 1 variant where the variant could not be matched at parse time
- fixed a bug where a non-variable-reference member of an "our" variable declaration list would cause a crash due to passing the incorrect argument in sprintf()
- fixed sandboxing / protection errors with inherited code; subclasses inheriting code from a parent class with different parse options would cause the child parse options to be used when running the parent class code which caused errors; now parse options are enforced properly on the block level
- fixed the RangeIterator class; it was still abstract due to a missing Qore::RangeIterator::valid() method
- fixed a bug where the wrong error was being returned after a connection reset (remote connection close) in sockets with integer recv*() methods which could in some cases lead to an infinite loop
- fixed a bug where private members of a common base class were not accessible by objects of subclasses sharing the common base class
- fixed many bugs in CsvUtil and updated the module version to 1.1
- initialize static openssl crypto locks for multi-threaded openssl library access; without this crashes can result (for example in error queue management)
- fixed a bug where Qore::HTTPClient::getURL() returned an invalid URL when no URL was set; now it returns NOTHING in this case
- fixed a bug managing feature/module lists in inherited Program objects; user modules were listed in the child Program object even though user module code is not imported in child Program objects
- fixed a bug where an invalid guard condition in critical lvalue storage code can cause unreferenced data to be returned while in a lock which can cause a crash in a multithreaded program
- fixed a bug where references were not being written to the output variable if an exception was active when the code block exited
- fixed a bug setting the precision for arbitrary-precision numbers with large exponents (like "1e100n")
- implemented more strict adherence to RFC 2616 (HTTP 1.1) regarding message-body handling in requests and response message generation and parsing
- fixed a bug with Condition::wait() on Darwin with negative timeout values where a short timeout was used instead of an indefinite wait
- fixed bugs in the SmtpClient and MailMessage modules where mail messages were being serialized incorrectly if there were no attachments (there was no possibility to set the content transfer encoding) and also where it was not possible to set the content-type for the message body when it was sent as a part of a multipart message
- fixed bugs handling arguments declared as type *reference (reference or nothing)
- fixed bugs in executing code accross Program object barriers with reference arguments
- fixed a bug with the switch statement where character encoding differences would cause strings to mismatch even if they were otherwise identical; now hard comparisons with strings allow for implicit automatic temporary character encoding conversions for the comparison
- fixed a bug where qore failed to set the time zone region correctly when set from /etc/localtime and this file is a relative symlink rather than absolute
- fixed a bug where substr() and <string>::substr() were returning NOTHING if the arguments could not be satisifed contrary to the documentation and the declared return type, now an empty string is returned in those cases
- fixed bugs rounding number values between 10 and -10 (non-inclusive) for display, fixed bugs rounding number value regarding digits after the decimal point for display with Qore::NF_Scientific
- fixed a bug in the Qore::Dir class where it was not possible to chdir to the root directory
"/"
- fixed a bug where recursive references were allowed and memory leaks would occur due to recursive references; these are now caught at runtime and a
REFERENCE-ERROR exception is thrown
- fixed a configure bug with bison >= 3
- fixed a bug in the HttpServer module when automatically uncompressing supported content-encodings to set the resulting string's character encoding correctly
- fixed a bug in the instanceof operator when working with objects and classes created from different source Program objects
- fixed a bug in *printf() formatting with floating-point and number values where no digits were displayed right of the decimal point unless a specific number of digits was specified in the format string
- fixed the return type of <bool>::typeCode(); was returning a boolean instead of Qore::NT_BOOLEAN
- fixed a bug there NULL was evaluated as True in a boolean context rather than False
- fixed a bug where Qore::Socket::recvBinary() would ignore the first data read
- fixed starting listeners on UNIX domain sockets on Soalris in the HttpServer module
- fixed a bug where number("") was being converted to @NaN@n
- fixed return type of HTTPClient::getConnectionPath()
- fixed several bugs with logical comparison operators and arbitrary-precision numeric values where arbitrary-precision numeric values were not being prioritized as numeric values and also in some cases were being first converted to doubles and then operated on
- fixed a bug in the socket code where the socket close condition was not flagged with SSL connections when writes failed due to the remote end closing the connection; an error would only be raised on the following socket operation
- fixed a mismatched delete/malloc error with time zone initialization and the localtime file
Qore 0.8.7
- Release Summary
- Code embedding improvements
Changes That Can Affect Backwards-Compatibility
- Fixes for Code Inheritance in Program Objects
- The following changes are meant to sanitize code inheritance in child Program objects to fix long-standing design bugs in code encapsulation by addressing the lack of fine-grained control over symbol visibility in inherited code.
- public: The public keyword's usage in modules has now been expanded to provide the same functionality generically in Program objects; if classes, constants, namespaces, functions, or global variables are defined with the public keyword, then these symbols will be inherited into child Program objects as long as no parse options prohibit it.
This change was made to give programmers complete control over which symbols are inherited in child Program objects, whereas because prior to this change, the control was very course.
- the default behavior of Qore regarding inherting global variables and functions with user variants was changed to be consistent with namespaces, classes, and constants; that is; public symbols are inherited by default.
The following constants were renamed:
- builtin symbols are no longer inherited from user modules; only independent user symbols; the main change is that if a user module adds new user methods to a builtin class or new user variants to a builtin function, these changes are no longer imported into target Program objects.
- File Method Changes
- The following methods were updated to throw exceptions on all errors rather than a return code for I/O errors in order to avoid hard to debug conditions due to ignoring I/O errors by forgetting to check the return value on the following methods:
Note that the above changes will hopefully only minimally impact backwards-compatibilty since the change is in error handling, and additionally each of the above methods could also throw an exception if called when the object was not open.
New Features in Qore
- new methods offering code encapsulation enhancements
- new pseudo-methods in <nothing> to allow for <hash> pseudo-methods to be safely used with NOTHING
- other new pseudo-methods:
- removed most restrictions on embedded logic in user modules; user module Program objects are subject to the same restrictions as the parent Program object (if any)
- added the get_parse_options() function so that parse options in the current Program can be determined at runtime
- added the get_ex_pos() function to help with formatting exception locations where the
source and offset information is present
- new methods and method variants:
- new location tags
"source" and "offset" added for parse and runtime exceptions to allow for error-reporting to display information about files where sections of a source file are parsed; this allows both the label and line offset in the label and the file name and absolute file line position to be reported in exception information
- new parameters added to the following methods and function to accommodate the new location information:
- see Exception Hash and Call Stacks for new keys in exception and call stack information hashes
- <date>::format() now accepts
"us" for microseconds (see Date Formatting Codes)
- SmtpClient module improvements:
- added automatic recognition and support of the
"STARTTLS" command when connecting to an ESMTP server; this way the class will automatically upgrade the connection to a secure TLS/SSL connection if the server supports it
- added support for SMTP server schemes in the URL in the constructor (ex:
"esmtptls://user@password:smtp.example.com")
- added support for the deprecated (but still in use)
"smtps" scheme with a default port of 465
- when throwing an exception when a Message cannot be sent because it is incomplete, the reason for the error is also included in the exception (previously the exception message was generic making problems with the Message object harder to debug)
- C++ API Enhancements
- added C++ APIs to allow for Qore File and Queue object arguments to be used by modules
- added C++ APIs for controlling openssl initialization and cleanup by the qore library
- extended qpp to allow for parsing relative dates in qpp code for assignments/default argument values
- made it possible to call the C++ function QoreFunction::findVariant() from threads where there is no current QoreProgram object (such as from a thread created by foreign code)
- added APIs to allow foreign threads to be registered/deregistered as Qore threads (for example, to allow Qore code to be called in a callback in a foreign thread created by a library linked with a Qore binary module)
- added APIs to allow for TID reservations to allow (for example) for a callback that is executed in the same foreign thread to always have the same TID
- the old Datasource::execRaw() function with the args parameter was deprecated since args was ignored anyway, a new Datasource::execRaw() function was added that has no args parammeter
Bug Fixes in Qore
- fixed a runtime class matching bug when identical user classes were created in different Program objects, the match could fail at runtime because the wrong APIs were being used
- fixed a crashing bug in the map operator with a select expression when used with an AbstractIterator object for the list operand
- fixed a bug where the generation of internal strings for abstract method signatures tries to resolve class names that are declared out of order, which incorrectly resulted in a parse exception; the fix is to use the class name in the signature before class resolution; the class is resolved in the second stage of parsing (symbol resolution) anyway, if it can't be resolved then the changes to the Program are rolled back anyway
- a potential deadlock was fixed when calling exit() while background threads were running; it was possible for a thread to be canceled while holding a Mutex (for example) and then for another thread to deadlock trying to acquire the Mutex and therefore for the process to deadlock because pthread_mutex_lock() is not a cancellation point. The solution was to cancel all threads first, then wait half a second, then call exit()
- fixed a bug where global variables were being evaluated with strict mathematical boolean evaluation even when %perl-bool-eval was enabled (which is the default)
- fixed bug in Qore::parseBase64String() and Qore::parseBase64StringToString() when called with an empty string argument; in this case uninitialized memory was returned
- fixed runtime dynamic memory leaks in the Select From List Operator (select) and Map Operator (map) operators when used with iterators
- do thread-specific cleanup in the main thread when cleaning up/shutting down the qore library
- added additional openssl cleanup code for thread-local data and when cleaning up the qore library
- fixed a bug matching function/method variants at runtime
- fixed a race condition deleting global dynamic handlers in the HttpServer module
- fixed a bug where declaring an abstract method with parameters and then declaring a concrete reimplementation of the method in a child class with no parameters caused a parse-time crash
- fixed a bug where trying to dynamically call a function that does not exist results in a deadlock due to an error where a mutex is not unlocked
- fixed a bug in the Qore::Socket::sendHTTPMessage() and Qore::Socket::sendHTTPResponse() methods regarding the timeout parameter
- fixed a bug in an socket SSL error message where the method name was printed from non-string memory (used wrong ptr for the
%s format argument)
- fixed some major crashing bugs related to reference handling; a global variable assigned a reference to a reference to a local variable would cause a crash
- reference and *reference type fixes: an error in reference type handling allowed non-reference values to be passed to builtin code expecing references which caused a crash; the reference and *reference types would accept any value type
- attempted to fix a non-reproducible bug seen on rhel5 in the Socket class where SSL errors would cause the affected thread to go into a infinite loop using 100% CPU
Qore 0.8.6.2
- Release Summary
- Iterator improvements and design fixes
Changes That Can Affect Backwards-Compatibility
- Fixes for Iterator Class Design Bugs
- Iterators, particular regarding the map and select operators, were implemented in a confusing and inconsistent way; even the qore documentation was incorrect, and examples were given incorrectly. The following changes will break functionality using the badly-implemented behavior of iterators before, but since the fix comes fairly soon after the introduction, hopefully this change will not cause too many problems with existing code. All users polled about the iterator changes in this release saw them as positive and desired changes to the language.
Changes in Qore
- new iterator classes:
- new pseudo-methods:
- the internal C++ QoreProgramHelper object has been updated to wait until all background threads in the Qore library have executed before taking the Program object out of scope; this allows for callbacks and other code that might be needed by background threads started in user modules (for example) to stay valid until the threads in the user modules also have terminated. Note that this does not affect the case when using %exec-class and an application program object goes out of scope with background threads in user modules having non-static method call references as callbacks to the application program; see Program Scope in Object-Oriented Programs Using User Modules Providing Their Own Threads for more information on this topic.
Qore 0.8.6.1
- Release Summary
- Major bug fixes and minor new features
Changes in Qore
- updated the %try-module parse directive to support a variant without an exception variable for usage in Program objects where Qore::PO_NO_TOP_LEVEL_STATEMENTS is set
- added code to raise an invalid-operation warning with the elements operator when called with a type that can never return a value with this operator
- updated the File class's internal buffer size from 4KB to 16KB which greatly improves read performance
- added new public APIs for the QoreNumberNode class to allow for proper de/serialization in external modules
- Pop3Client module:
- added the Pop3Client::logPassword() methods and masked password by default in the debug log
- updated module to v1.1
- Mime module:
- declared the MultiPartMessage::getMsgAndHeaders() method abstract as originally intended
- added MultiPartMessage::parseBody() static method
- updated module to v1.3
Bug Fixes in Qore
- fixed crashing bugs due to the lack of proper lvalue checks with the expression for the background operator with operators using lvalues with local variables
- fixed rounding of arbitrary-precision numeric values for display purposes when the last significant digit is just to the right of the decimal point (ex: was displaying 10.2 as "11." for example)
- fixed a race condition in static destruction of the library when a background thread calls exit() that could cause a segfault on exit
- fixed a static memory leak in Program objects when constants contain code references to functions or static methods
- fixed a bug parsing user modules; the Program context was not set properly which could lead to a crash when parsing user modules loaded from the command-line or to incorrect parse options when loaded from user Program code
- fixed a bug where the invalid-operation warning with the keys operator was not being triggered in common cases that should have triggered the warning
- MailMessage module:
- fixed recognizing mime messages with additional text after the version number (ex:
"Mime-Version: 1.0 (Mac OS X Mail 6.2 \(1499\))")
- fixed a bug setting the content-type of message parts (this fix is now in the Mime in the MultiPartMessage::getMsgAndHeaders() method
- fixed multipart message parsing by using MultiPartMessage::parseBody() in the Mime module; now also parts with subparts are parsed correctly as well
- fixed a bug where the sender and from values were not being set properly when parsing email messages
- updated module to v1.0.3
Qore 0.8.6
- Release Summary
- Major new features and a few bug fixes
Changes That Can Affect Backwards-Compatibility
- Perl-Style Boolean Evaluation
- Qore's default boolean evaluation mode was changed from strict mathematical to a more intuitive perl- (and Python-) like style. This change was implemented to address one of the oldest design bugs in Qore: strict mathematical boolean evaluation. See %perl-bool-eval for a description of the new default boolean evaluation mode.
To get the old strict mathematical boolean evaluation, use the %strict-bool-eval parse option.
An example of the change; now the following if statement block will be executed as the if expression is now evaluated as True: string str = "hello";
if (str)
printf("Qore says hello\n");
if expression above would be evaluated as False because the string value was converted to an integer 0, however as of Qore 0.8.6 (with the default perl-bool-eval) it is True since the string is not empty; empty strings and string value "0" are evaluated as False.
Perhaps counterintuitively (and the reason this was changed to be the default in qore), the chance for regression errors in qore code is very small, because for all cases where the old logic could be applied (meaning excluding cases where the result was always False due to the data types or values being evaluated), the results are the same with the new logic, except for one case; the case where a string has more than one character and begins with a zero (ex: "00"). In this case, the old logic would always return False, because the value was first converted to an integer 0, whereas the new logic will return True. Note that in the case of a string with a single "0", both the old and new boolean logic returns False.
Basically with this option set, qore's boolean evaluation becomes like perl's and Python's, whereas any expression that has the following values is False: NOTHING, string "0" and empty strings, integer, float, and number 0 (zero), absolute date 1970-01-01Z (ie the start of the epoch with an offset of 0), relative date 0s (or any relative date with a 0 duration), NULL, empty binary objects, empty hashes, and empty lists. All other values are True.
- Note
- also affects the boolean(any) function
- Changes in the Socket Class
- The Socket class was enhanced to support timeouts with non-blocking I/O on all send operations; many Socket methods that send data were originally implemented to return an error code on error, however they would also throw exceptions if the socket were not open, so the error handling was inconsistent (exceptions versus return codes).
Additionally it was not possible to get error information at all for SSL errors if the socket was connected with SSL, which, according to Qore's socket design, should be transparent for the programmer.
For these reasons the implementation was deemed inconsistent and unintuitive; the change was to add optional timeout parameters to all send methods and to allow the methods to throw exceptions (instead of simply returning -1 and not being able to determine the cause of the error in many cases).
The following methods were updated to accept optional timeout parameters and throw exceptions on all errors rather than a return code for I/O errors:
- New Abstract Method in AbstractIterator
- The following abstract method was added:
- Qore::AbstractIterator::valid() was added (with concrete implementations in all iterator classes derived from this base class delivered with Qore); this method tells if the object is currently pointing to a valid iterator.
For any user classes inherting AbstractIterator directly (as opposed to another concrete iterator class in Qore, where the method has already been added), a concrete implementation of this method will have to be added as well or that class will become Abstract Methods with this release of Qore.
New Features in Qore
- Arbitrary-Precision Numeric Support
- Qore now uses the MPFR and GMP libraries to provide arbitrary-precision numeric support. This type can be used for high-precision mathematics or for storing
NUMERIC (ie DECIMAL or NUMBER) column values when retrieved from databases by Qore DBI drivers that support the new capability DBI_CAP_HAS_NUMBER_SUPPORT (previously these values would be retrieved as Qore strings in order to avoid information loss).
For more information, see the new number type, number, and <number>
- New CsvUtil Module
- The CsvUtil module implements the CsvFileIterator class that allows for easy parsing of csv-like text files
- %try-module Parse Directive to Handle Module Load Errors at Parse Time
- The new %try-module parse directive allows for module load errors to be handled at parse time; ex:
%try-module($ex) some-module > 1.0
printf("error loading module %y: %s: %s\n", ex.arg, ex.err, ex.desc);
exit(1);
%endtry
- Abstract Class Hierarchy Improvement
- As of this version of qore, concrete implementations of abstract methods no longer have to have exactly the same return type as the abstract method; it is now sufficient that the return type in the concrete method meets a compatibility test with the return type of the abstract method in the parent class.
For example the following is now valid (and MyConcreteClass is not abstract, whereas previously because the return types in the child class were not exact, MyConcreteClass would be considered abstract by qore): class MyAbstractClass {
abstract any doSomething();
abstract *string getString();
}
class MyConcreteClass inherits MyAbstractClass {
int doSomething() {
return 1;
}
string getString() {
return "hello";
}
}
- DBI Improvements
- Three new DBI capabilities were implemented, including a new option API as follows:
- DBI_CAP_HAS_NUMBER_SUPPORT: DBI drivers declaring this capability can accept number values and can also return number values, if a DBI driver does not declare this capability, then number values sent for binding by value are automatically converted to float values before being sent to the driver
- DBI_CAP_HAS_OPTION_SUPPORT: this indicates that the driver supports the new option API, allowing options to be set on each connection. See the following for more information:
- DBI_CAP_SERVER_TIME_ZONE: indicates that the DBI driver will convert any bound date/time values to the server's time zone before binding and also will tag date/time values retrieved from the server with the server's time zone. This capability also implies that the driver supports the new
"timezone" option.
- Socket Improvements
- The Socket class was updated to support non-blocking I/O on all send methods; the following methods were updated to accept optional timeout parameters:
The following methods were enhanced to provide better error information when throwing exceptions:
- Iterator Improvements
- The following improvements were made in qore to support more flexible and ubiquitous iterators:
- new iterator classes:
- new pseudo-methods were added to return iterator objects based on the value type:
The base pseudo-method (<value>::iterator()) ensures that any value can be iterated, and the type-specific methods ensure that the most suitable iterator for container types is returned for container values; values without an iterator class are iterated with the SingleValueIterator
- the HashIterator and HashReverseIterator classes had an additional optional boolean argument added to their constructors; if True, then the HashIterator::getValue() and HashReverseIterator::getValue() methods return a hash with the following keys:
"key" and "value", allowing for more convenient iteration with constructions that only use getValue() methods (such as the foreach statement); to accommodate this, two new methods were added to the HashIterator base class:
- all iterator classes had copy methods added to them (ex: Qore::HashIterator::copy())
- new Python-inspired range() and xrange() functions (the latter returning a RangeIterator object to efficiently iterate large integral sequences or ranges
- Text File Parsing Enhancements
- The following improvements were made in qore to support more flexible file parsing:
- the Qore::ReadOnlyFile class was added as a parent class of Qore::File to allow for a more convenient API for reading files (the Qore::File class's API remains the same as it publically inherits Qore::ReadOnlyFile)
- the ReadOnlyFile::readLine() method (formerlly a method of the Qore::File class) was enhanced to accept 2 optional arguments, allowing the end of line character(s) to be stripped from the line returned, and also to allow the end of line characters to be specified. If no end of line characters are specified, then the method automatically determines the end of line characters (can be
"\n", "\r", or "\r\n"; the last one only if the underlying file is not a TTY in order to avoid stalling I/O on an interactive TTY)
- the File Stat Constants were moved from the Qore::File class to the Qore::ReadOnlyFile class
- added a new FileLineIterator iterator class
- added a new optional parameter to <string>::split(string, string, bool) and Qore::split(string, string, string, bool) to allow for automatic stripping unquoted fields of leading and trailing whitespace (the default is the old behavior; i.e. leave the whitespace as it is read)
- added a new TimeZone method for parsing string dates in a specific TimeZone: Qore::TimeZone::date(string, string)
- added a new function for parsing text as a boolean value: parse_boolean()
- as mentioned above, the new CsvUtil module was added, implementing the CsvFileIterator class that allows for easy parsing of csv-like text files
- Other Improvements and Changes
-
Bug Fixes in Qore
- fixed a bug in the map operator with a select expression when the list operand is NOTHING; it was returning a list with one NOTHING element instead of NOTHING
- applied a patch by Reini Urban to allow for multi-arch builds on Debian
- fixed bugs calculating the byte offset for string searches in the c++ QoreString::index() and QoreString::rindex() functions when the offset is negative and the strings have a multi-byte character encoding (such as UTF-8)
- fixed a bug where calling an abstract method from a class where the abstract method is implemented was causing a parse error to be thrown
- fixed a bug where the wrong source code location was displayed when raising a parse exception in operator expression parse initialization for some operators
- fixed bugs in regexes in the HttpServer::addListeners() and HttpServer::addListenersWithHandler() methods (HttpServer module version updated to 0.3.5)
- fixed bugs handling non-blocking reads in the Socket class; the timeout setting was only enforced for the first read; subsequent reads were made as blocking reads
- fixed a bug in the Socket class when the SSL session requires renegotiation during non-blocking I/O
- File::constructor() now throws an exception if called with a tty target and %no-terminal-io is set
- fixed a bug in split with quote (<string>::split(string, string, bool) and Qore::split(string, string, string, bool)) if the separator pattern was not found and the single field was not quoted either
- fixed a bug handling nested %ifdef and %ifndef blocks with %else in the inside block
- fixed a crashing due to the failure to clear the "PF_TOP_LEVEL" flag when initializing statements, this could cause temporary variables in a statement to be marked as the start of the global thread-local variable list, and then after such variables are deleted, then a crash happens when trying to access the global thread-local variable list
- fixed a crashing bug at parse time merging function lists in namespaces declared multiple times
- fixed a bug in executing user module init() closures
- fixed a bug where the qore library could crash when destroying a Program object due to a race condition in removing signal handlers managed by the Program object; the Program calls the signal handler manager to remove the signals, but the signals can be removed concurrently to the request while the Program object is iterating the signal set (ie it is modified while being iterated), which causes a crash
- added code to detect when the same namespace is declared both with and without the public keyword when defining user modules which can result in entire namespaces being silently not exported (and can be difficult to debug); now a parse exception is thrown if this happens while parsing a user module
- added code tags to File methods without side effects
- made many minor documentation fixes
Qore 0.8.5.1
- Release Summary
- Bugfix release
Bug Fixes in Qore
- fixed a race condition accessing global and closure-bound thread-local variables in multithreaded contexts
- fixed a bug in transaction management with the DatasourcePool class when used with the SQLStatement class
- fixed an error in the MailMessage user module where mail headers requiring encoding were not encoded and those not requiring encoding were encoded with Q encoding
- fixed an error in the Mime user module where
"_" characters in q-encoded headers were not encoded correctly
Qore 0.8.5
- Release Summary
- Major new features and a few bug fixes
New Features in Qore
- Abstract Methods and Interfaces
- Qore now supports the abstract keyword when declaring methods; an abstract method has no implementation and must be implemented in child classes with the same signature for the child class to be instantiated.
Classes with abstract methods define interfaces; a concrete implementation of the interface is a class that inherits the class with abstract methods and implements all the abstract methods.
Abstract methods are defined with the following syntax: class MyAbstractInterface {
abstract string doSomething(int param);
abstract bool checkSomething(string arg);
}
- Universal References
- All restrictions on references have been removed from Qore; references to local variables may now be passed to the background operator and passed as arguments to closures.
Basically when a reference is taken of a local variable that could result in the local variable being accessed in a multi-threaded context, the variable is treated as a closure-bound local variable in the sense that it's lifetime is reference-counted, and all accesses are wrapped in a dedicated mutual-exclusion lock to ensure thread safety.
- Pop3Client Module
- A Pop3Client module has been added providing an API for communicating with POP3 servers and retrieving email messages.
The module uses functionality provided by the new MailMessage module to represent email messages (and attachment data) downloaded from the server.
- MailMessage Module
- The MailMessage module provides common functionality to the Pop3Client and SmtpClient modules to represent email messages for receiving and sending, respectively. This module was created mostly from functionality removed from the SmtpClient and enhanced to provide support for reading email messages in the new Pop3Client module.
- SmtpClient Module Changes
- The Message and Attachment classes were removed from the SmtpClient module to the MailMessage module. Backwards-compatible definitions for the Message and Attachment classes are provided in the SmtpClient module to rexport the removed functionality for backwards compatibility.
- Other Minor Improvements and Changes
- qpp updated to support abstract methods and multiple inheritance (+ other minor qpp enhancements)
- improved the
QOREADDRINFO-GETINFO-ERROR exception description by adding information about the arguments passed
- added a string argument to char(softint, *string) to accept an output encoding
- added a int(string, int) variant to parse a string as a number and give the base
- added a new parameter to parse_url() and parseURL() to allow for any [] in the hostname to be included in the
"host" output key for indicating that the ipv6 protocol be used
- added the following pseudo-methods:
- added the xxhash FAST algorithm with unordered_map to Qore on supported platforms resuling in nearly 2x haster hash lookups
- added the Qore::File::isOpen() method
- added the Qore::call_pseudo() function to explicitly call a pseudo method on a value
- added the Qore::symlink() function to create symbolic links
- added Qore::TypeCodeMap and Qore::TypeNameMap to lookup type codes from type names and vice versa
- added the following functions to allow the time zone to be set per thread:
Bug Fixes in Qore
- fixed format_date() output for
"MON" and "DAY", etc
- fixed a memory leak in the parser related to parse exception handling with namespace members
- fixed an invalid assert() in module handling when an error occurs loading the module (only affected debug builds)
- tagged digest and crypto functions internally as RET_VALUE_ONLY
- do not kill TID 1 (the initial / main thread) when calling exit() in background threads as a crash can result with some 3rd party libraries that spawn their own threads on some platforms (observed on Darwin & Solaris 10 at least)
- fixed a memory bug in the new builtin function API used by modules built with qpp
- fixed memory bugs in the type system where uninitialized type pointers could be used causing a crash
- fixed a memory bug in handling "or nothing" types where a non-null pointer would be assumed to be a pointer to the type, however it could actually be a pointer to the NOTHING object, the fix was to ensure that any NOTHING objects in argument lists would be substituted with a null pointer
- fixed a bug in parse-time variant matching where an argument with parse-time type "object" would be matched as a perfect match to any parameter with any class restriction; this would cause run-time type errors if another valid class was passed that matched another variant of the method or function
- fixed a build bug that caused qore to be built twice
Qore 0.8.4
- Release Summary
- Major new features and changes that can affect backwards-compatibility, plus 40 bug fixes
Changes That Can Affect Backwards-Compatibility
- Namespace Changes
- Qore's internal namespace handling was nearly completely rewritten for Qore 0.8.4. This is because the old code was inefficient and applied namespaces inconsistently to Program objects.
The main change that can cause backwards-compatibility issues is that now functions are full namespace members. If no namespace is explicitly given in a function definition, the function is a member of the unnamed root namespace.
Also the distinction between builtin and user functions was removed. Internally, there is only one kind of function object, which can contain both builtin and user function variants (overloaded variants of the same function with the same name but different arguments).
All Qore builtin functions were moved to the Qore namespace.
Other namespace changes:
- loading namespaces provided by builtin modules into a Program object is now an atomic operation that may fail, if, for example, objects have already been defined in the target Program with the same name as objects provided by the builtin module. Previously this could cause undefined behavior.
- namespace lookups are now truly breadth-first as documented; previously the algorithm was depth-first (contrary to the documentation)
- namespace lookups are now done (both at parse time and runtime) with the help of symbol lookup tables for fast lookups; tables are maintained for both committed and temporary uncomitted parse symbols; this leads to up to 3x faster parsing for Qore code
- global variables are also now full namespace members, however this does not cause problems with backwards-compatibility
New Features in Qore
- User Modules
- It is now possible to develop user modules in Qore; several user modules are now included in the Qore distribution, forming Qore-language components of Qore's runtime library.
User modules delivered with Qore 0.8.4:
- HttpServer: a multi-threaded HTTP server implementation
- SmtpClient: an SMTP client library
- TelnetClient: a TELNET client implementation
- Mime: a set of MIME definitions and functions for manipulating MIME data
There are also new example programs for the above modules in the examples/ directory.
User modules are subject to Qore's functional restriction framework.
- Namespace Changes
- As listed above:
- global variables and functions are now full namespace members
- all builtin functions are now in the Qore namespace
- real depth-first searches are used for namespace symbols
- symbols are resolved first in the current namespace when parsing declarations/code in a namespace
- The
final Keyword - Classes and methods can now be declared "final" to prevent subclassing or overriding in a subclass
- Pseudo Methods
- Pseudo-methods are class methods that can be implemented on any value; they are also part of class hierarchy. The methods that can be executed on the value depend on the value's type, and all "pseudo-classes" inherit methods from a common base class.
For example: "string".strlen()
<abf05da3>.size()
500.typeCode()
Some expensive operations such as getting the first or last key (or value) of a hash are now cheap using pseudo-methods, for example: hash.firstKey()
hash.lastValue()
- New Doxygen-Based Documentation
- The Qore reference documentation is now generated by Doxygen, and is generated directly from the Qore sources. In fact, a new preprocessor known as "qpp" was developed for Qore 0.8.4 to facilitate and enforce doxygen documentation on Qore's runtime library (as well as abstract the relatively complex APIs used to bind C++ code to the Qore runtime library from the C++ programmer).
The documentation is more comprehensive, and corresponds much closer to the actual internal implementation since the documentation is now also contained in and directly generated from the internal C++ implementation of Qore.
For example, there is the <value>::val() method. This method is implemented in the base pseudo class and is reimplemented in other pseudo-classes for other runtime data types as necessary. This method returns True if the value has a value in the same sense as Perl's boolean context evaluation. For example, if the value is a hash with no keys, it returns False; if it is a hash with keys, it returns True; if it is an empty string, it returns False; if it is a non-empty string, it returns True, etc.
- LValue Handling Changes
- lvalue handling was rewritten as the old implementation was ugly and subject to deadlocks (in rare corner cases).
Furthermore, medium-term, an architectural goal of Qore is to store all ints, floats, and bools internally as the basic C++ type instead of using a class wrapper for each value, which needs dynamic allocation and destruction, which takes up more memory and negatively affects execution speed.
With Qore 0.8.4, all local and global variables are stored using optimized C++ types when declared with the appropriate type restrictions; for example: These declares local and global variables that can only be assigned integer values; in Qore 0.8.4 the value internally will be stored as an "int64" value (and not a dynamically-allocated QoreBigIntNode object).
The same holds for:
Note that the optimized lvalue handling has not yet been applied to all lvalues, in particular non-static object members with declared types are not yet implemented with optimized storage; to do this requires a rewrite of Qore's API and ABI (will happen in the next major release of Qore).
This change leads to improved integer and floating-point performance and a smaller runtime memory footprint.
- Runtime Optimizations
- In addition to the up to 3x faster parsing (as decribed in the namespace changes above), Qore 0.8.4 contains many runtime optimizations designed to reduce the number of dynamic memory allocations performed at runtime.
The optimizations included in this version of Qore are only a half-measure compared to future changes that will necessitate a new binary Qore API.
- Per-Thread Initialization
- the new set_thread_init() function allows a call reference or closure to be set which will be automatically executed when new threads are started (or a new thread accesses a Program object) which can be used to transparently initialize thread-local data.
- More Control Over Thread Resource Exceptions
- new functions:
- throw_thread_resource_exceptions_to_mark()
- mark_thread_resources()
Allow for only thread resouces created after a certain point to be processed (for example only thread resources left after some embedded code was called)
- New Socket Methods
- new methods:
Allow upgrading an already-existing socket connection to SSL
- Better Socket Error Messages
- More information has been added to socket exceptions to provide better feedback when errors occur.
- New Socket Event Fields
-
- Support For Blocking Writes in the Queue Class
- Queue objects can now be used as a blocking message channel (similar to a Go channel); if a maximum size is given to the Queue constructor, then trying to write data to the Queue when it is full will block until the Queue's size goes below the maximum size; optional timeout parameters have been added to Queue methods that write to the Queue.
- New Queue::clear() Method
- Does just what you think it does :)
- date(string, string) Improvement
- added the possibility to specify microseconds when parsing dates against a mask with the date() function
- New Support For ++ And – Operators With Floating-Point Lvalues
- previously this would either convert the lvalue to an int or throw an exception if the lvalue could not be converted to an int due to type restrictions
- Class Recognition/Compatibility Between Program Objects
- The problem is that a user class created from the same source code in two different Program objects would be recognized as a different class with parameter and variable type restrictions - ie you could not declare a variable or parameter with a class type restrictions and assign it an object created from the same class source code but created in another Program object.
This problem is analogous to a similar problem with java in that classes built from the same source but from different classloaders are also recognized as different classes.
In Qore 0.8.4 a class signature is created of all public and private objects, and an SHA1 hash is maintained of the class signature, and if the class names and signatures match, then the classes are assumed to be identical, even if they have different internal class IDs (because they were created in different Program objects, for example).
- New TimeZone::date(string) Method
- to support creating arbitrary dates in a given TimeZone
- New GetOpt::parse3() method
- This method will display any errors on stderr and exit the program (which is the most typical way of handling command line errors anyway)
- += Operator Optimization For object += hash
- this operation is faster in this release
- New Parse Option PO_NO_MODULES
- Using this option disables module loading
- New Parse Option PO_NO_EMBEDDED_LOGIC
- Using this option disables all dynamic parsing
- New Parse Directives
-
- New Context Functions
- cx_value(): returns the value of the given key
- cx_first(): returns True if iterating the first row
- cx_last(): returns True if iterating the last row
- cx_pos(): returns the current row number (starting from 0)
- cx_total(): returns the total number of rows in the set
- SOCKET-HTTP-ERROR Exception Enhancement
- The invalid header info received is reported in the exception's
"arg" key
- Improved Parse Error Messages
- Improved some parse error messages dealing with namespace and class declaration errors
- Added NT_CLOSURE Constant
- type code for runtime closure values
