Comment on attachment 330629 [details] Patch v1 View in context: https://bugs.webkit.org/attachment.cgi?id=330629&action=review Looks good so far. Bot catches a bunch in: Source/WebKitLegacy/mac/Misc/WebNSDataExtras.m > Source/WebKit/Platform/cocoa/WKCrashReporter.mm:48 > - char* oldMessage = (char*)CRGetCrashLogMessage(); > + char* oldMessage = const_cast<char*>(CRGetCrashLogMessage()); > if (oldMessage) > free(oldMessage); Not caused by your changed, but this code raises multiple red flags: - How do we know we can free this data, anyone outside of WebKit could have called CRSetCrashLogMessage with their own string. - Why would we free the oldMessage here, but not care to free any potential value in the earlier case we overwrite the value (line 41-42).

Yep, you're correct! As currently written this would leak the previous message if a NULL CFStringRef were passed in. The code to free the old message should happen before the (!infoString) check.

This is the bug fix to free the old message. The bug happened if a message had been set previously, then nullptr was passed to clear it out (prior to this change). >> Source/WebKit/Shared/cf/ArgumentCodersCF.cpp:197 >> #endif > > Why not use checked_cf_cast for these instead? Because this code above already does a type check to turn the object into an enum: CFType type = typeFromCFTypeRef(typeRef); It seemed redundant to do yet another type check. >> Source/WebKit/Shared/mac/WebCoreArgumentCodersMac.mm:404 >> + CFDictionarySetValue(const_cast<CFMutableDictionaryRef>(userInfo.get()), NSUnderlyingErrorKey, underlyingNSError.get()); > > This should be done without the cast, like this: > > auto mutableUserInfo = adoptCF(CFDictionaryCreateMutableCopy(kCFAllocatorDefault, CFDictionaryGetCount(userInfo.get()) + 1, userInfo.get())); > CFDictionarySetValue(mutableUserInfo.get(), NSUnderlyingErrorKey, underlyingNSError.get()); > userInfo = WTFMove(mutableUserInfo); Will fix. >> Source/WebKitLegacy/mac/Misc/WebNSDataExtras.mm:2 >> + * Copyright (C) 2005-2018 Apple Inc.

The option to make git-diff output show the changes with the rename didn't work when I used webkit-patch. 2) I will post another patch and make sure it has the changes. >> Source/WebKitLegacy/mac/WebView/WebPDFView.mm:141 >> + NSString *appPath = [(NSURL *)appURL path]; > > Some day we should change this to use -[NSURL fileSystemRepresentation] instead of -[NSURL path]. Interestingly, we don't use [NSURL getFileSystemRepresentation:maxLength:] anywhere in WebKit, but we do use [[NSURL path] stringByStandardizingPath] in one place (HTMLConverter.mm) and -stringByStandardizingPath a number of places. Also, WebCore::URL::fileSystemPath() creates a CFURLRef and then uses CFURLCopyFileSystemPath() to get the path. Is there any preferred way of doing this?

Yes, you fixed that and it is not the bug I am referring to The bug I am referring to, something you discussed earlier in this report, I believe is that this code assumes that CRGetCrashLogMessage will return a message string set by this function or null string. But someone else could call CRSetCrashLogMessage. This function needs to instead keep around the string it allocates in a global variable and destroy the old string based on the value of that global, not call CRGetCrashLogMessage. That’s a separate fix that should be done at some point so this is a less dangerous function to use. It’s straightforward to fix; simply add a static char* that holds the value. We’ll know we have it right because we won’t be calling CRGetCrashLogMessage at all and we also need to make sure that we call CRSetCrashLogMessage before destroying the old value. >>> Source/WebKitLegacy/mac/WebView/WebPDFView.mm:141 >>> + NSString *appPath = [(NSURL *)appURL path]; >> >> Some day we should change this to use -[NSURL fileSystemRepresentation] instead of -[NSURL path]. > > Interestingly, we don't use [NSURL getFileSystemRepresentation:maxLength:] anywhere in WebKit, but we do use [[NSURL path] stringByStandardizingPath] in one place (HTMLConverter.mm) and -stringByStandardizingPath a number of places. > > Also, WebCore::URL::fileSystemPath() creates a CFURLRef and then uses CFURLCopyFileSystemPath() to get the path. > > Is there any preferred way of doing this? Thinking it through I realize I was wrong. It’s fine to use -[NSURL path] here. The main difference between the two methods is that -[NSURL fileSystemRepresentation] converts to a C-style string to make it easy to pass to POSIX functions like fopen, but that is not something we need here; we are using NSWorkspace, which takes an NSString, not a C-style string. The stringByStandardizingPath method is a separate matter, not closely related, and there is almost never a need to use it when using a path to operate on a file. It can be helpful in code that has a reason to store a path for later use, such as in preferences, but exactly what methods to use in that case can be a complex topic.

The setCrashReportApplicationSpecificInformation() function is already using the gCRAnnotations global defined in WKCrashReporter.mm: // Avoid having to link with libCrashReporterClient.a CRASH_REPORTER_CLIENT_HIDDEN struct crashreporter_annotations_t gCRAnnotations __attribute__((section("__DATA," CRASHREPORTER_ANNOTATIONS_SECTION))) = { CRASHREPORTER_ANNOTATIONS_VERSION, 0, 0, 0, 0, 0, 0, 0 }; <https://trac.webkit.org/browser/webkit/trunk/Source/WebKit/Platform/cocoa/WKCrashReporter.mm#L31> That's how the CRGetCrashLogMessage/CRSetCrashLogMessage macros work: <https://trac.webkit.org/browser/webkit/trunk/Source/WebKit/Platform/spi/Cocoa/CrashReporterClientSPI.h> Sorry if that wasn't clear in my ChangeLog message.

I guess gCRAnnotations could technically be modified by other code since it's not declared as static, but someone would have to go out of their way to do that since gCRAnnotations is not declared in Source/WebKit/Platform/cocoa/WKCrashReporter.h. Maybe I'm still missing something? Or do we want to be extra careful here by saving a second copy of the char* pointer inside setCrashReportApplicationSpecificInformation()?
