/api /apievents Issues Fixed
| Bug ID | Severity | Description | Change |
| 614 | MINOR | original file source information not available in service code at runtime in track traces and exception info | fixed in Qorus |
| 613 | MINOR | original file source information not available at runtime in job code in track traces and exception info | fixed in Qorus |
| 612 | CRITICAL | the error status from a detach function can affect the next step executed in the same thread even if the step is actually COMPLETE | fixed in Qorus |
| 611 | CRITICAL | parse options are not enforced properly on the block level, also subclasses inheriting code with different parse options will cause the child parse options to be used when running the parent class code which causes errors | fixed in the qore library |
| 610 | CRITICAL | if a non-variable reference is included in an "our" variable declaration list, a parse-time crash will result due to a memory error in the parser | fixed in the qore library |
| 609 | CRITICAL | service APIs using event APIs can get into a spinlock condition when the system is shutdown as there is no indication that the internal API is returning immediately due to a system shutdown condition | fixed in Qorus |
| 608 | MINOR | oload fails to load system services and user services in the same call because it creates the internal service library incorrectly | fixed in oload |
| 607 | NORMAL | a bug related to out-of-order parse initialization for functions and methods can result in the wrong return type being returned for a method with more than 1 variant where the variant cannot be matched at parse time | fixed in the qore library |
| 606 | NORMAL | parse exceptions and warnings when validating types used with the return statement can be reported at the wrong source location | fixed in the qore library |
| 605 | MINOR | the info component of warning messages is repeated in the workflow log files | fixed in Qorus |
| 604 | NORMAL | parse exceptions for empty blocks with a missing return statement are reported at the wrong source location | fixed in the qore library |
| 603 | CRITICAL | public members and static variables of privately-inherited classes are incorrectly treated as public attributes of the child class | fixed in the qore library |
| 602 | MAJOR | invalid unique index on the workflow_errors table makes it impossible to associate more than one workflow-specific error against a workflow | fixed in Qorus |
| 601 | NORMAL | parse exceptions in base class constructor arguments could be reported at the wrong source location | fixed in the qore library |
| 600 | MINOR | illegal arguments passed to class copy methods are ignored and never executed | fixed in the qore library |
| 599 | CRITICAL | declaring a parameter type for copy methods causes the copy method to be unable to be called | fixed in the qore library |
| 598 | CRITICAL | a parse-time crash will occur when calling the copy() method for a class that does not implement an explicit copy() method | fixed in the qore library |
| 597 | NORMAL | it's not possible to output a single '\' character in a regex substitution expression: a single '\' is taken as an escape code, and '\' is output literally | fixed in the qore library |
| 596 | MINOR | when rescheduling a READY order with a future date, the workflow status is not updated to SCHEDULED | fixed in Qorus |
| 578 | CRITICAL | an error managing failed SSL connections causes the qorus process to take 100% CPU usage and must be killed after shutdown as well | fixed in the qore library |
This release was mostly a bugfix release; see below for more information.
Issues Fixed
| Bug ID | Severity | Description | Change |
| 595 | NORMAL | parse exceptions resolving global variables could be reported at the wrong source location | fixed in the qore library |
| 594 | NORMAL | system events for workflow order instance creation are not emitted when subworkflow order instances are created | fixed in Qorus |
| 593 | NORMAL | error_instance rows are not created when errors happen in the detach function | fixed in Qorus |
| 592 | NORMAL | the autostart flag is updated by oload even if manually set by operations with the API | fixed in oload and in Qorus |
| 591 | NORMAL | the qore library can sometimes show the incorrect source location when type errors are found in function or method calls | fixed in the qore library |
| 590 | MAJOR | some broken sftp servers set the file's mode to 0 when opening a file read-only when using the ssh2 module | fixed in the ssh2 module |
| 589 | CRITICAL | changing the global retry_delay or async_retry options in workflow code during a workflow reset in the onetimeinit function can cause a spurious exception and results in a condition where qorus has to be killed to be shut down | fixed in Qorus |
| 588 | MAJOR | oload ignores service code outside of method declarations, previously this code was included in the following code object | fixed in oload |
| 587 | MINOR | classes with unimplemented inherited abstract variants can sometimes throw runtime exceptions when instantiated but should instead be caught at parse time | fixed in the qore library |
| 586 | NORMAL | the ? : operator gives the wrong types at parse time resulting in incorrect parse type errors | fixed in the qore library |
| 585 | MINOR | oload does not refresh the step map when inserting or updating steps | fixed in oload |
Qorus 2.8.0 is a minor release over the Qorus 2.7 Series branch, however bringing major new features to the Qorus platform. It is based on the Qore 0.8.7 library, which contains major new features over previous versions of Qore as well.
Due to the RBAC changes in this release, existing user security configurations (meaning application permissions and access groups associated to users) are migrated to new custom single-use roles which are created by the upgrade logic in the Qorus application installation script and are associated only to the user being migrated.
After the migration the updated user-tool script or the updated RBAC system APIs can be used to review, change, delete, or coalesce roles and users as desired.
The goal of the migration logic is to leave existing users with the same security configuration as before the upgrade, however represented with the corrected RBAC model.

If another workflow defines the same error with different parameters, then a workflow-specific version of the error is stored in WORKFLOW_ERRORS."manually_updated". If this flag is set to True, meaning that the error has been updated through the API, then the manually-updated error will not be overwritten by definitions in workflow error functions."TAG: " and then the tag name followed by another colon and the tag value.
