What's new in Euphoria Programming Language 3.1.1
Sep 3, 2009
- bug fixed: A storage leak (memory allocated but never freed) was introduced in version 3.1, on the Linux and FreeBSD platforms. Fixed by Matthew Lewis.
- bug fixed: When Euphoria failed to open the main program file, the error message would sometimes show the wrong file type. Fixed by Matthew Lewis.
- bug fixed: Bugs in the new library routines, find_from() and match_from() were corrected. The third argument (the starting index) is now tightly-checked. Fixed by Matthew Lewis and Rob Craig.
- bug fixed: The ed script on Linux was changed to allow blanks in the path of the file to be edited. Fixed by Rob Craig.
- bug fixed: Double-quotes were added to ed.ex so Esc e will work with paths containing blanks. Reported by Alex Caracatsanis. Fixed by Rob Craig.
- bug fixed: database.e was fixed so forward slashes are allowed in the db_compress() file name. Reported by Frank Dowling. Fixed by Rob Craig.
New in Euphoria Programming Language 3.1 (Sep 3, 2009)
- New Features:
- New built-in routines, find_from() and match_from() have been added. These work like find() and match() but they let you start searching from any element in the sequence, not necessarily at element 1. This makes some algorithms simpler and much faster. Implemented by Matthew Lewis.
- When searching for an include file specified with a relative (i.e. not absolute) file path, Euphoria will check first for a file relative to the location of the current source file. If not found, then the usual rules will apply, i.e. it will check relative to the main program file, then check the EUINC directories (if any), and finally euphoriainclude. Suggested by C.K. Lester and, in various forms, by several other people. Implemented by C.K. Lester. Checked in by Matt Lewis.
- ex int.ex (in euphoriasource) will now work, since the interpreter now supports machine_proc(65,...) which passes IL to the fast C-coded back-end. You can also run int.ex with exw or exu. This lets you easily modify the front end and get a modified Euphoria interpreter, for all platforms, that runs programs at full speed (much faster than the Euphoria-coded execute.e). You might also bind int.ex to get a single executable file for whatever platform you like.
- If the user does not supply a filename with an extension, Euphoria will attempt to open the file first with the standard extension for its respective platform, but if it does not find it, it will also look for files with the standard extensions for the other platforms. Implemented by Matthew Lewis.
- Translator: The limit on the number of additional .c files that can be created per Euphoria file has been raised from 36 to well over 1000.
- New Documentation:
- The "storage cache" compression technique that's used for bound executables and .il files, was documented in comments added to compress.e. It reduces the size of the IL by 30% or more, while allowing fast decompression.
- A documentation file, tasks.doc, was added to euphoriademolangwar. It describes the multiple tasks used in Language War.
- Bug Fixes:
- bug fixed: Translator: Translated code for routine_id() erroneously returned -1 when a global symbol was looked up which matched a symbol in the same file as the call to routine_id(), as well as a global symbol in another earlier file. It was treated incorrectly as a multiply-defined symbol that was lacking a namespace qualifier. Thanks to Daniel Kluss.
- bug fixed: Translator: In rare situations, a naming conflict could occur when more than one .c file is created for a Euphoria file. Thanks to DB James.
- bug fixed: Translator: get_key(), when translated/compiled with Borland or LCC, required an extra keystroke after a carriage return. Implemented by Jacques Deschenes.
- bug fixed: Source Code Portability: euphoria.h: CLK_TCK is now defined as CLOCKS_PER_SEC if not defined previously in the source. Implemented by Matt Lewis.
- bug fixed: Installer: Double-quotes were added around several filenames used in the INNO installer script (though this did not seem to affect many people).
New in Euphoria Programming Language 3.0.2 (Mar 2, 2007)
- Translator: Programs translated to C and compiled for Windows would crash if they used the new multitasking feature. (This worked in 3.0.0 but was broken accidentally in 3.0.1 because some stack offsets changed.)
- Interpreter: In fairly rare situations, the interpreter for Windows might crash. This was due to a bug in load_private_block() where it was freeing a block of memory and then returning a pointer into that block. In rare cases, a page of virtual memory might be removed from the heap by the Windows O/S before the block could be read. Thanks to Andy Serpa, Pete Lomax, Matt Lewis, Derek Parnell, and others for helping to pin-point the location of the bug.
- Source Code: "euphoria" was changed to to %EUDIR% in 4 .bat files in the source directory. Thanks to Jaime Marcos.
- A new document (translator.doc) was added to euphoriasource. It describes the internals of the Translator, with emphasis on the many optimizations that the Translator performs.
- The user documentation was also improved in a few places.
- Matthew Lewis added a Linux/FreeBSD make file, and made source code changes to better support Open Watcom and a newer version of GCC.
