ReqChange V1.14 Revision history ReqChange V1.14 Revision history for ReqChange ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ReqChange V1.0 20 Jan 1992 ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Initial release. ReqChange V1.1 23 Jan 1992 ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Added support for multiselect (ASL). Hey, it was easier than I thought! But I must say the Autodocs could be more specific on the matter... :) Silly bug in argument handling removed. Now should arguments be handled properly (I forgot to add a #define when I added an option...). The Install script will now copy ReqChange's icon, and will have SYS:WBStartup/ as default destination for ReqChange. The fontrequester doesn't always show the style gadgets anymore (i.e. only if that is requested). The IGNOREHEIGHT option didn't work exactly as intended... Now the REQHEIGHT value will be doubled, if the requester is on its way up on an interlaced screen (or a screen which is higher than 400 pixels). The file/font requester patches didn't handle tags coming in. They do now. Other minor bugs removed. ReqChange V1.1a 30 Jan 1992 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Found (and fixed) a little bug in the ASL patches. If you had a device name as the only directory specification, a '/' was incorrectly added. Program is now more compact (and should load faster too. No relocation information is in the program, which is in one single hunk). Parts of code has been optimized (especially the assembler part), registerized arguments have been used (possible thanks to the new DICE version I got the other day). Page 1 ReqChange V1.14 Revision history ReqChange V1.14 A little bug in the stack-swapping routines fixed (really, it was a nasty one, but I guess it wouldn't appear very often...). Other minor bugs stamped. ReqChange V1.2 4 Feb 1992 ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Changes in ReqChange: Added the CENTERSCR and CENTERWIN switches. CENTERSCR makes all requesters to be centered on the screen (thanks to Nils Sj÷holm for suggesting this), while the CENTERWIN (added this one for completeness...) will make all requesters to be centered within the parent window (if the calling task didn't supply a pointer to any window, the requester will be centered on the screen instead). CENTERWIN will override CENTERSCR if both are used at the same time. Changes in GetFile and ReqAsk: Added the GLOBAL switch to ReqAsk and GetFile (so they can be used from ARexx). Added the MULTISELECT switch (mainly intended to be used from ARexx) and the PATTERN keyword to GetFile (and again, thanks to Nils Sj÷holm for suggesting this). GetFile will now always quote a filename if it contains any spaces. Included a GetEnv.Rexx script, to make it easier to get the results from ReqAsk and GetFile (as long as the GLOBAL flag has been used). ReqChange V1.2a 8 Feb 1992 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Discovered that ReqChange didn't close ASL when terminating. Fixed. Improved error handling a bit. Now its only if dos.library or intuition.library didn't open ReqChange silently quits. All other errors are shown. Removed some bugs during init if ARP or ASL didn't get opened. They made it impossible to remove ReqChange later on. Some other bugs removed. Page 2 ReqChange V1.14 Revision history ReqChange V1.14 ReqChange V1.3 12 Feb 1992 ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Finally! ReqChange will now auto-detach! This means that you don't need to Run ReqChange anymore. If started from CLI, most error messages will be shown on the console (some errors still appears as a requester thought. Can't do much about it really :). Note that WShell 2.0 will complain about a "***Hanging forbid!", but I can't do much about that, due to the way the auto-detaching is implemented. A few logic bugs removed. Although they shouldn't appear normally (definitively not with ASL V37.27), there was a potential source of problems. New version of reqtools.library included (V37.718, also called 1.0c). Found out that Nico Franτois is working on a similar program. The main difference is that his version has full support for req.library, but no support for asl (and mine has full asl, but no req... :). His program also requires that NO one uses req.library or arp.library when the patch is installed, to use some special tricks to get buffered files all the time etc (if I understand/guessed everything correctly... :). If you are using OS 2.04, ReqChange is to prefer, since many programs uses the asl.library if running under OS 2.04. And his program will probably cause a guru or two under 2.0+.. :) This is because his program does NO STACK SWITCHING on the Auto/EasyRequest patches. This is necessary, since e.g. Workbench assumes it can make a call to EasyRequest with a quite small stack. Also, "Please insert.." requesters (especially if AssignX is installed) will probably cause a GURU... Conclusion: Use ReqChange instead! :) Those of you stuck with 1.3 might find Nico's program useful though... The problems mentioned above is with RTPatch (as he calls his program) V0.9▀... Thus, some (or all) problems might be fixed in later versions. Added the CENTERTEXT switch, which makes all information-requesters' text to be centered (i.e. each line of the text is centered). When checking if the REQHEIGHT value should be doubled or not, ReqChange will check against the height of the visual portion of the screen instead of the height of the whole screen. Added shortcuts to some of the paramters. Added separate centering control for information requesters and filerequesters. The old switches affects the information requesters, while the switches with "FR" in front of them affects Page 3 ReqChange V1.14 Revision history ReqChange V1.14 the filerequesters. ReqChange V1.4 29 Feb 1992 ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Since the ReqToolss*.lib that were included with ReqTools V1.0c for DICE were incorrect, new, correct versions are supplied (look in the LibSrc.run archive). The error was that the rtReqHandler glues didn't save a6, which DICE assumed it should do (i.e. it wasn't DICEs fault... :). Those libraries were also large-data model ones, although the names implied that they were small-data ones (it wasn't fun to modify the source for that! :). Interesting... Discovered a bug, but after compilation, the code worked exactly as intended anyway! Fixed the bug though (although it probably added a few bytes of code.. :), to prevent any future problems. Now patches all functions in req.library with the equivalents in ReqTools! Supports all important features in Req V2. This includes directory-caching in the filerequester, timeout and abortmask in the TextRequest function etc. Minor bug in CLI error report fixed (a cosmetic bug). Discovered that my version of the FontRequester structure was faulty. I never noticed this bug since most programs that uses it first allocates a structure, then calls the requester routine, and then frees the requester as soon as the relevant data has been copied. Thus, the faulty requester was never passed to the original requester if ReqChange was removed (or ReqChange called the original function because it ran out of memory). The AutoRequest patch needed some more work.. Now it will sort all textlines in the body text after their y position, so that they show up properly in the requester (select the DiskCopy icon with any version prior to ReqChange V1.4 to see what I mean... :). The sort is a simple shellsort, so it is quite quick (although the amount of data to sort normally is very low... :). A number of other bugs fixed (more or less serious.. Discovered them by looking at the source => they didn't normaly show up..) ReqChange V1.05 01 Apr 92 ~~~~~~~~~~~~~~~~~~~~~~~~~~ Hey, there are many changes in this version! :) Btw, this version is 4 bytes smaller than the previous... Improved some size calculations for the REQ patches (so that Page 4 ReqChange V1.14 Revision history ReqChange V1.14 they work according to the way ReqTools work). Found a bug in the patch for REQ's filerequester. It had some problems with multiselections. If the calling program specified a multiselect limit of zero files - which should mean 65535 according to REQ - then ReqChange interpreted that as zero. Ooops... Forgot to include the *.lib files with the previous release... :) They are included in this one instead (Extra/LibSrc.Lha). Found a bug in the ARP patch (the check for the LongPath bit was faulty..), which made long directory specifications only partially copied back in the callers structure (sometimes this can happen even now when this bug has been fixed! There is nothing I can do about that though...). The REQ and ARP patches now understands some not so oftenly used features regarding the directory name. REQ splits the name if the directory specification happens to be a valid filename, while ARP allows a pattern to be used in place of what normally should be the filename. If any of the patches runs out of memory, they will return FALSE instead of calling the original function. This saves some bytes, and if the patches were short on memory, it ain't that likely that the original function will succeed either (this change was also needed due to the changes in the ASL patches, noted below)... Since AssignX didn't work that well when ReqChange was installed (due to differencies in ASL and ReqTools), a simplified version of AssignX has been built into ReqChange (didn't "steal" any code, but the basic idea was taken from AssignX by Steve Tibbet). Refer to the NOASSIGN parameter for further info on this subject. ReqChange will now convert '*' to '#?' (where this is needed) in patterns. This was needed for users that didn't have StarBurst or equivalent in their startup sequences. Thanks to Johan Billing for reporting this problem. New version of ReqTools included (V37.726), which also is called 1.0d. ReqChange will still swap stack if needed, although some of the functions in this new version of ReqTools does this too (increases safety, and I don't need to check exactly which version of ReqTools that is installed). CX_PRIORITY argument removed! There was no need for it, so I removed all code handling it, to save some bytes. The ASL patches have changed A LOT! Please read the manual again! These changes have (hopefully :) made ReqChange *much* safer, regarding new versions of ASL. I hope no compatibility Page 5 ReqChange V1.14 Revision history ReqChange V1.14 problems will show up now. The IGNOREASLCHECK parameter has been obsolete because of this, so that one has been removed. You can't use Disable/Enable any more either (this would cause too much trouble and/or waste memory). REQHEIGHT and IGNOREHEIGHT parameters have been replaced by MINHEIGHT and MAXHEIGHT, which gives greater flexibility. When checking for the "(min|max)height doubling", only the height of the screen will be considered, not if it is interlaced or not. Lots of internal bugfixes (too many to mention them here) and cleanups (including some C -> asm conversion, to reduce the size). ReqChange V1.06 11 Apr 92 ~~~~~~~~~~~~~~~~~~~~~~~~~~ ReqChange now works on 1.3 systems too! ARP required for this though. Some programs (incorrectly) assmed that ASL wouldn't touch a4 (when calling a hook function). This made ReqChange crash with such programs. Although the programs in question are the faulty one, ReqChange has been fixed so that it restores a4 before calling any hook. Thanks to Stefan Stuntz and "ScottE" (don't know his real name! :) for telling me about this problem. ReqChange know autodetaches, even if started from WorkBench. This is useful in the WBStartup drawer. If no DONOTWAIT field is present, ReqChange will not return until it has installed its patches. If you have some other patch program in WBStartup (e.g. MFR), this prevents some randomness in the order of which the patches gets installed (if you also have different STARTPRI for the different patches). Thanks to Stefan Stuntz for this suggestion. If the MINHEIGHT value is greater than the MAXHEIGHT value, the two will be swapped (didn't check for this in previous version... :). ReqChange V1.07 13 Apr 92 ~~~~~~~~~~~~~~~~~~~~~~~~~~ Real stubid bug in detach routine fixed.. Caused severe problems if ReqChange was started from Workbench. Thanks to Scott Ellis ("ScottE") for discovering this problem (maybe I should have done a bit more debugging before releasing new versions... :). Another stupid bug fixed.. The PathName field in the REQ filerequester patch wasn't correctly filled in under OS 1.3. Page 6 ReqChange V1.14 Revision history ReqChange V1.14 ReqChange V1.08 16 Apr 92 ~~~~~~~~~~~~~~~~~~~~~~~~~~ A couple of stupid bugs in the "AssignX" code removed. If the EasyRequest patch was about to return 2 (i.e. at least 3 gadgets, and the gadget just to the right of the leftmost gadget was pressed), a filerequester was fired up, even if this shouldn't happen. Return values could also be incorrect sometimes. Added check so that it's only when a process is calling that we allow the "AssignX" code to come in action (safety only, no problems discovered). Sure hope this version is ok.. :) I haven't got the time to test this version properly, as I'm going home over Easter today, and I wanted this bugfix out as soon as possible. ReqChange V1.09 04 May 92 ~~~~~~~~~~~~~~~~~~~~~~~~~~ The ASL patches will now buffer the contents of the file/font requester between calls. Use NOFILEBUFFER and/or NOFONTBUFFER to disable this. Fixed a bug that made ReqChange crash when terminating after a Workbench start under OS 1.3. Fixed a bug in GetFile, by splitting the FILE argument into a DIR and a FILE argument. Before GetFile would split the FILE argument, when there was no need to do so (hard to know if the path should be splitted or not). The ASL patches that handles the allocation of a FileRequester structure didn't sometimes back up properly if they ran out of memory. They have also been rewritten so that these structures normally uses somewhat less memory, especially if any (or both) of the NO(FILE|FONT)BUFFER flags are set. Fixed a real strange bug in the REQ filerequester patches. Somehow CED 'renamed' (this is the way it seemed to be, what really happened, I simply don't know) the file it got from a filerequester. I do not know where the bug was, or how I removed it, but it seems to be gone by now... :) Thanks to Frank Hoffsuemmer for reporting this bug. Other bugs in the REQ filerequester patches removed (ReqChange didn't properly fill some of the fields. I noticed this when I tried View80 II). Page 7 ReqChange V1.14 Revision history ReqChange V1.14 When trying to load/save something with the OS 2.04 prefs-editors, nothing would happen (at least not with some of them). This "bug" - that was introduced in ReqChange V1.05 - have now been fixed, although it really is the prefs-editors fault. They are not well written, and does not follow the "recommendations" in asl.h. These editors write into read only structures, and assumes certain fields that are "reserved" is used for some particular thing. This also means that sometimes the filerequester is missing e.g. a title. Thanks to Frank Hoffsuemmer for reporting this bug. ReqChange sometimes crashed when doing an assign under 1.3 (Thanks to Gerald G. Washington, who reported this problem, but it took a while before I really found it though :). It worked the first few times I tested it, but the bug involved a certain amount of randomness. Anyhow, the problem was that the 1.3 OS was doing some stack switching before calling AutoRequest() to display the "Please insert..." requester. This swap was done in a way very similar to how ReqChange worked (by only changing the a7 register, and leaving the TC_SPLOWER and TC_SPUPPER fields of the task-structure untouched), and this caused the stackswap routine in ReqChange to think that the stack-size was enough, when it really wasn't (the OS allocated a stack on 2048 bytes, which was too little for us). Therefore I made ReqChange to *always* swap in a new stack, and doing this in a way so that other stack-checking routines doesn't fail of the same reason the routines in ReqChange failed. All this to be on the safe size, although it uses some more memory, but I really have no choise... :( ReqChange V1.10 16 May 92 ~~~~~~~~~~~~~~~~~~~~~~~~~~ Some internal changes and optimizations. Resulted in a smaller executable (about 1 Kb!). Made the removal code safer (and somewhat smaller). I've never had any problems, but it never hurts to be on the safe side. The ARP patch didn't use the MINHEIGHT value to get the height of the requester. Fixed. Argument handling radically changed. All that used to be switches now takes an argument, either that specifies if the feature should be on or off, or something else. They have also been renamed. For convenience when doing a CLI-start, most flags defaults to on (this is the way it used to be). Please check the manual! Shortcuts in arguments cannot be used anymore! Sigh.. Discovered that I had an older version of reqtools.library included than the manual stated (the newer library Page 8 ReqChange V1.14 Revision history ReqChange V1.14 should be V37.276 for the 2.0 version according to documents included in the 1.0d release of ReqTools, but the library has the same version number as the 1.0c release, V37.718. They are different though...). Modified stack swap routines again. Now it will swap the stack if we're low on stack or the stack have been (improperly) swapped by someone else. This is the best solution (I hope... :). On OS 2.04 and ARP didn't successfully open, ARP would still be patched! Fixed. The FILEBUFFER/FONTBUFFER flags are now global (i.e. affects the REQ patches too). The code that was responsible for freeing ASL requesters would not free all requesters if the FILEBUFFER and/or FONTBUFFER flags were off. Fixed. The failure path if a filerequester allocation in ASL failed was bad. Fixed. ReqChange V1.11 21 Jun 92 ~~~~~~~~~~~~~~~~~~~~~~~~~~ Re-enabled shortcuts for CLI start. No shortcuts available among ToolTypes. The ON/OFF scheme for arguments is now obsolete, but ReqChange still understand these switches. Use YES/NO instead (for compatibility with "normal" Commodities). Many internal changes, to reduce size and ease coding. Window interface added! Works on OS 2.0 only. Because of this, the arguments CX_POPUP, CX_POPKEY and CX_PRIORITY have been added. This means that ReqChange is a "full-blown" commodity now. Added "Mount" and "Deny" to the "AssignX" part (Paul Howett). Two new centering types added, TOPLEFTWIN and TOPLEFTSCR. Also added offset-arguments, TOPOFFSET and LEFTOFFSET, which affects all centering modes except POINTER. ReqChange will now remember the pattern between calls in the ASL patch, unless changed by the calling program in some way (Oliver Kasper). The ASL patches didn't free any multi-selected files when the requester was freed. And when they tried to free them (which could happen if a requester was fired up twice with the same structure), Page 9 ReqChange V1.14 Revision history ReqChange V1.14 a guru would appear. These bugs should have been fixed long ago! :( The patch for AutoRequest now uses a bit less memory (and is slightly faster, but I doubt you'll notice that). IDFILE argument added (upon request). If specified, ReqChange will try to send an apropriate message to Upd when that is needed (i.e. you get requesters "with sound effects"). Please read the manual for further information. Rewrote the DICE-glue for ReqTools, so that it can generate largedata versions too. During this, another bug in the libs was found, regarding the _rtEZRequestA function. When fetching arguments from the stack, the a2 register wasn't filled in, and a3 and a4 got wrong data. Fixed an old bug in the openlibrary routine. Would show the "Ignore" gadget when it shouldn't, and vice versa. The ASL patches will no longer add any '/' to the directory name. Why can't some programs (like Commodores Ed) use proper routines for adding a filname to a directory name?? :( (Steve Galle) The ASL fontrequester patch will now set the fontname properly, before showing the requester. The min/max-height doubling on high screens didn't work for all requesters. Fixed. ReqChange V1.13 05 Aug 92 ~~~~~~~~~~~~~~~~~~~~~~~~~~ Major update! Maybe should call this 1.20 instead?? :) Sigh... Stupid little mistake caused that docs and programs stated (mostly) that it was 1.12 rather than 1.11 in the previous release. The archive was named ReqChange1_11.run though. Because of this, I see myself forced to call this V1.13... :) The mistake was cause by my semi-automated revision system, in combination with last-minute changes and some "ignorance" from my part... :( Stupid (but not serious) bug regarding the REQ patches removed. Didn't show up often though ('less than' when it should be 'less than or equal' in a compare). Some enforcer hits (i.e. bad behaviour) stomped. Quickly fixed thanks to a good bug-report. Took me about 5 minutes to locate and remove the bug! (Franz Schwarz) When ReqChange shows a requester that it failed to remove itself, it will now give you the option to retry to remove ReqChange. Page 10 ReqChange V1.14 Revision history ReqChange V1.14 Some more code rewritten into assembler, to reduce size. Now requires ReqTools V2.0 (V38)! This version is ofcourse included. POP argument added. Decide if requesters should pop the screen they appear on to the front or not. ASL filerequester patch now allows user to enter an empty filename in the filerequester (thanks to a new feature in ReqTools 2.0). They also support so called IntuiMsgFuncs. The DICE-glue for ReqTools have been updated to reflect ReqTools V2.0. Fixed bug so that ReqChange no more will complain about a bad CX_POPKEY argument, when the default argument was used. Only seemed to happen on certain Amigas. (Richard Hartmann) Fixed some bugs in the init code. Also, cleanup code should be safer now. No problems encountered, but I thought it was best to fix it anyway. Fixed a bug that caused ReqChange to crash if certain errors occured during startup. (Found thanks to the CX_POPKEY bug) The ASL filerequester patch will now always return a multiselection list when multiselect is enabled, even if only one file was selected. (Franz Schwarz) Rewrote the manual quite a bit. The ASL filerequester patch now understand a not so oftenly used feature regarding the directory name. ASL allows a pattern to be used in place of what normally should be the filename (as ARP works..). But this pattern is ignored by ReqChange at the moment (Ok, I could use a so called hook to fix this (not so good solution), or make a double pattern like "(a|b)", where "a" is the normal pattern, and "b" is the pattern found in the dir-buffer (better solution), but I don't consider this as important. I have not yet seen a program that uses this feature :). Fixed a "bug" in the ASL filerequester patch (i.e. a missing "feature" has been added) that caused rexxarplib.library to get strange returns on multiselected files in the getfile function. (Franz Schwarz) A fix to the AutoRequest() patch in V1.4 had became "unfixed" by mistake. Fixed it again (sort all textlines in the body text after their y position) Page 11 ReqChange V1.14 Revision history ReqChange V1.14 Window interface now looks somewhat different (and *much* better :) ). The window is no longer a SIMPLE_REFRESH one due to this. BACKFILL argument added. Specifies if the GetString() and GetLong() changes in REQ should have a backfill pattern in the requester or not. Key shortcuts added in window interface and in all requesters generated by ReqChange. Some memory was not freed after (trying) to save the settings. Fixed. The settings window will now use the same centering mode as the filerequesters. (A Mattias Johansson) The "AssignX" part now disables DOS requesters while trying to mount or make an assign. Just for safety. The "AssignX" part now also understands translated system requesters! (locale.library on OS 2.0, or SRT (mainly on OS 1.3)). Thanks to Olaf Barthel for this, since I "borrowed" the idea from his program AssignWedge. Fixed the GetLong() patch to that it doesn't show the default value when it shouldn't (which could happen sometimes). (Andreas M. Kirchwitz) ReqChange will no longer try to open the window interface if you managed to send it a break f signal on OS 1.3. This would lead to a guru... :( SignalRC program included, to make it easier to send break signals to ReqChange (especially needed on OS 1.3). ReqChange V1.14 04 Sep 92 ~~~~~~~~~~~~~~~~~~~~~~~~~~ The filename field in the idfile requester wasn't properly filled in. Fixed. Now ReqChange will *really* wait until the patches have been installed (or for a maximum of 5 seconds). ReqChange didn't really wait all the time in 1.13.. New version of Upd (1.20) included. The "iconified" settings window will now be placed in the upper left corner of the screen. The setting window will look a little better on 1 bitplane Page 12 ReqChange V1.14 Revision history ReqChange V1.14 screens now. Fixed a "bug" that (potentially) could cause "read from location zero" problems. Don't know if it actually could happen (depends on some ROM routines. The usual problem: The AutoDocs doesn't mention what happens in some certain cases... :) Added enable/disable possibility again! This also means that the gadgets in the Changes section in the window interface really affects the changes right away (if so possible. If not, the patches will be as transparant as possible). (Franz Schwarz) Rewrote the patching routines, so that the libraries only are patched if the library in question is opened (ala the routines in RTPatch). Intuition will always be patched though. This also made ReqChange less likley to be locked in memory, in case some buggy program forgot to free/purge a file/font requester (for this to work, the buggy program must at least close the library properly). The settings window will now follow the state of the BACKFILL flag. The settings window will now use the screen font (if fixedwidth, otherwise system default font). Quite simple routines actually (*very* easy to modify the source, after having written a few, small and simple routines), inspired by the principels in GadToolsBox by Jan van den Baard (only a bit better... :). Seems to work quite well (although not perfect...), especially considering they only added 500 bytes to the program! :). Added a quit-confirmation requester. Found a bug (using MungWall), that was introduced in 1.13. It occured when freeing a multi-selection list in the ASL patches. Fixed. The ARP FileRequest() patch will now share the IDCMP port with the caller's window (unless told to not to), if such should exist. Fixed a bug in the window interface. If any gadget creation failed, some memory might be freed twice. Made some minor cosmetical changes in ReqAsk and GetFile. Rewrote the ARP patch into assembler. While at it, I also added support for the DoWildFunc (could be called "program controlled pattern"). If this feature is seldom used, I think it has a reason... :) The docs are incorrect. It claims the DoWildFunc gets a FileInfoBlock as object. It doesn't. It gets an AnchorPath structure. Fixed a real stupid bug which could lead to a crash if there was Page 13 ReqChange V1.14 Revision history ReqChange V1.14 an error while reading the idfile on OS 1.3. New version of reqtools.library included (38.810). May the Amiga be with you! Page 14
