2018-04-22SCI: Change workaround for PalVary / Animate race conditionWillem Jan Palenstijn
The new approach is to delay kAnimate briefly (with an 68ms timeout) while there is a zero-tick PalVary running, so that it has time to trigger. The previous workaround would immediately process a zero-tick PalVaryInit/PalVaryReverse. This caused problems in QfG3 (bug #10304) where it interfered with PalVaryPause. The previous workaround could also be modified to handle pause/resume, but this new approach should be closer to SSCI's behaviour, which used a timer for a zero-tick PalVary too. This fixes bug #10304, and keeps #5298 fixed too.

2018-04-07ALL: Load savegame thumbnail only when necessaryAdrian Frühwirth
This commit introduces the following changes: 1. Graphics::loadThumbnail() Now returns a boolean and takes a new argument skipThumbnail which defaults to false. In case of true, loadThumbnail() reads past the thumbnail data in the input stream instead of actually loading the thumbnail. This simplifies savegame handling where, up until now, many engines always read the whole savegame metadata (including the thumbnail) and then threw away the thumbnail when not needed (which is in almost all cases, the most common exception being MetaEngine::querySaveMetaInfos() which is responsible for loading savegame metadata for displaying it in the GUI launcher. 2. readSavegameHeader() Engines which already implement such a method (name varies) now take a new argument skipThumbnail (default: true) which is passed through to loadThumbnail(). This means that the default case for readSavegameHeader() is now _not_ loading the thumbnail from a savegame and just reading past it. In those cases, e.g. querySaveMetaInfos(), where we actually are interested in loading the thumbnail readSavegameHeader() needs to explicitely be called with skipThumbnail == false. Engines whose readSavegameHeader() (name varies) already takes an argument loadThumbnail have been adapted to have a similar prototype and semantics. I.e. readSaveHeader(in, loadThumbnail, header) now is readSaveHeader(in, header, skipThumbnail). 3. Error handling Engines which previously did not check the return value of readSavegameHeader() (name varies) now do so ensuring that possibly broken savegames (be it a broken thumbnail or something else) don't make it into the GUI launcher list in the first place.

This wasn't explicitly marked as intentional but it very much looks it. Committing separately in the unlikely case this needs to be reverted.

2018-02-01SCI: Avoid (false positive) uninitialized use warningWillem Jan Palenstijn
2018-02-01SCI: Sabotage qfg1vga's speed testWillem Jan Palenstijn
This ensures the detected speed will end up at the highest level. This improves the detail in Yorick's room (96), and slightly changes the timing in other rooms. Fixes bug #10296.

Fixes Trac#10416.
2018-01-16SCI32: Fix PQ4 Barbie shoe points patch selectorDavid Fioramonti
The original script patch had the correct literal value but the wrong selector name in the comment for the literal value, so when it was converted to use a selector lookup in c5dce17b1f1392feb8825aba5addbc3999eeaa51, the patch broke because the wrong selector name was used. Fixes Trac#10392. Closes gh-1107.

2017-12-03SCI: Avoid buffer overflow in amigamac sound driverWillem Jan Palenstijn
By default, frac_t is interpreted as signed. The resulting range isn't large enough to store offsets, so we interpret it as unsigned here instead. Fixes a crash in QfG1/Mac where instrument->loop_size is 49457.

2017-11-19SCI: Fix UB shifting negative integersColin Snover
2017-11-11SCI32: Fix integer overflow calculating audio durationColin Snover
Due to the need to calculate the audio duration with millisecond precision from the file size, it is possible to overflow a 32-bit integer in games with long background audio loops, like RAMA, during the calculation of the duration. It is also not necessary to give some framerate here, so eliminate the unnecessary explicit Timestamp construction with the second argument.
2017-10-29SCI: Fix UB in SegManager memcpy/strcpy operationsColin Snover
Passing overlapping buffers to C standard library memcpy, strcpy, and strncpy is undefined behavior. In SSCI these operations would perform a forward copy, and most stdlib implementations do the same, but at least newer Linux glibc on x86 copies bytes in reverse, so just using the standard library on this platform results in broken output. Because SSCI used a blind forward copy instead of memmove for overlapping copy operations, this patch implements an explicit forward copy to ensure that overlapping copies continue to operate the same as in SSCI. This fixes the Island of Dr. Brain v1.1 flamingo puzzle (script 185, flamingos::init, localCall 4c3) on platforms that do not perform forward copy in memcpy/strcpy/strncpy. Thanks to @moralrecordings for research on this bug and an initial patch using memmove. Closes gh-1034.

2017-10-21SCI: Fix offsets in disasm for multi-param opcodesWillem Jan Palenstijn
This code was assuming that retval points to the start of the next instruction, which is only true if the current parameter is the last one. This fixes op_call printing.
2017-10-16SCI32: Fix cursor color when quitting for phant1David Fioramonti
When quitting the game at the main menu and hitting no or quitting the game while playing the cursor color over the buttons will be tan the first time rather than red. This fix makes it so it will be red. This was done by removing a check in HotSpot::doit() which checks the global193 value. Removing this check fixes the problem. Fixes Trac#9977. Thanks snover and wjp for your help.
2017-10-15SCI32: Tell OSystem to show/hide cursors as appropriateColin Snover
This is needed so that the system cursor can be appropriately hidden outside the game's draw area, to match the normal behaviour of ScummVM.

2017-10-07ENGINES: Remove default1x scaler flagColin Snover
This flag is removed for a few reasons: * Engines universally set this flag to true for widths > 320, which made it redundant everywhere; * This flag functioned primarily as a "force 1x scaler" flag, since its behaviour was almost completely undocumented and users would need to figure out that they'd need an explicit non-default scaler set to get a scaler to operate at widths > 320; * (Most importantly) engines should not be in the business of deciding how the backend may choose to render its virtual screen. The choice of rendering behaviour belongs to the user, and the backend, in that order. A nearby future commit restores the default1x scaler behaviour in the SDL backend code for the moment, but in the future it is my hope that there will be a better configuration UI to allow users to specify how they want scaling to work for high resolutions.

This reverts commit ae8e4fa8e95f3ae347dfc681330bccc0b09d1f01. This change is wrong in any case. It should be specific to temp 14+15 at the very least. I also did not get an answer on what is actually happening internally. That's not how we should add workarounds. My review was also still pending.

2017-10-07SCI: Add workaround for uninit read during wordsearch in castlebrainDavid Fioramonti
During the wordsearch puzzle (room 320 click left door) the game will crash because of an uninitalized read of temp variables in word::dispatchEvent (which gets called a lot), if the player clicks the same letter or different letters aggressively or holds down the enter key. Fixes Trac#9783.
