Go 1.12 introduced a change to the internal map representation where empty map cells can be marked with a tophash value of 1 instead of just 0. Fixes #1531

RestoreRegisters on linux would also restore FS_BASE and GS_BASE, if the target goroutine migrated to a different thread during the call injection this would result in two threads of the target process pointing to the same TLS area which would greatly confuse the target runtime, leading to fatal panics with nonsensical stack traces. Other backends are unaffected: - native/windows doesn't store the TLS in the same CONTEXT struct as the other register values. - native/darwin doesn't support function calls (and wouldn't store the TLS value in the same struct) - gdbserial/rr doesn't support function calls (because it's a recording) - gsdbserial/lldb extracts the value of TLS by executing code in the target process.

* *: use loglevel to control what gets logged instead of output redirection This stops logrus from doing all the formatting just to discard it immediately afterwards. * logflags: replace default formatter of logrus The default formatter of logrus emits logs in two different formats depending on whether or not the output is going to a terminal. The output format for non-terminals is indented to be machine readable, but we mostly read logs ourselves and the excessive quoting makes that format unreadable. When outputting to terminals it uses ANSI escape codes unconditionally, without checking whether the terminal it is connected to actually supports colors. This commit replaces the default formatter with a much simpler formatter that always uses a more readable format, doesn't use colors and places the key-value pairs at the beginning of the line (which is a better match for how we use them). * cmd/dlv: add command line options to redirect logs Adds two options, --log-to-file and --log-to-fd, to redirect logs to a file or to a file descriptor. When one of those two options is specified the "API server listening at:" message will also be redirected to the specified file/file descriptor. This allows clients that want to use the "API server listening at:" message to do so even if they want to redirect the target's stdout to another file or device. Implements #1179, #1523

Adds initial support for plugins, this is only the code needed to keep track of loaded plugins on linux (both native and gdbserial backend). It does not actually implement support for debugging plugins on linux. Updates #865

Like we do with unrecovered panics, create a default breakpoint to catch runtime errors that will cause the program to terminate. Primarily intended to give users the opportunity to examine the state of a deadlocked process.

runtime.clone (on some operating systems?) work similarly to fork: when a thread calls runtime.clone a new thread is created. For a short period of time both the parent thread and the child thread appear to be running the same goroutine, until the child thread adjusts its TLS to point to the correct goroutine. This means that proc.GetG for a thread that's currently running 'runtime.clone' could be wrong and, consequently, the field proc.(G).thread of a G struct returned by GoroutinesInfo could be also wrong. And, finally, that FindGoroutine could sometimes return a *G with a bad associated thread if the goroutine of interest recently called 'runtime.clone'. To work around this problem this commit makes two changes: 1. proc.GetG will return nil for all threads executing runtime.clone. 2. FindGoroutine will return the selected goroutine as long as the ID matches the one requested. Change (1) takes care of the 'runtime.clone' problem. If we stop the target process shortly after a thread executed the SYSCALL instruction in 'runtime.clone' there are three possibilities: a. Both the parent thread and the child thread are stopped inside 'runtime.clone'. In this case the state we report is slightly incorrect, because both threads will be reported as not running any goroutine when we do know which goorutine one of them (the parent) is running. This doesn't actually matter since runtime.clone is always called on the system stack and therefore the goroutine in runtime.allgs will have the correct location. b. The child thread managed to exit 'runtime.clone' but the parent thread didn't. This is similar to (a) but in this case GetG on the child thread will return the correct goroutine. GetG on the parent thread will still return (incorrectly) nil but this doesn't matter for the samer reason as described in (a). c. The parent thread managed to exit 'runtime.clone' but the child thread didn't. In this case GetG will return the correct goroutine both for the parent thread (because it's not executing runtime.clone) and the child thread. Change (2) means that even if a thread has a completely nonsensical TLS (for example because it's set through cgo) evaluating a variable with a valid GoroutineID will still work as long as it's the current goroutine (which is the most common case). This change also doubles as an optimization for FindGoroutine. Fixes #1469

When compression is applied by default running the DWZ tool on the resulting binary will crash. The actual default compression code will look and see if compression makes any difference and if so replace the normal `.debug_*` section with `.zdebug_*`. This is why it may not have been hit before. On one of my workstations I build with 1.12rc1 and no compression happens, but on a Fedora VM I build and the binary results in compressed DWARF sections. Adding this flag will make this test more consistent overall.

* config/config.go This change checks for the environmental variable XDG_CONFIG_HOME before storing the configuration file in the home directory. Closes #1454 * config/config.go This change attempts to move the previous config file location to the new XDG_CONFIG_HOME compliant location on linux systems or when XDG_CONFIG_HOME is set. This change removes the old config file location if the file is successfully moved. * config/config.go Consolidate messages about config moving and clean up into one. Remove extraneous newlines. * pkg/config: config path error messages print to stderr This change updates the output location of error messages related to the config path. This will prevent clients from getting unexpected output when an error occurs. * pkg/config: Update path used when returning unable to move config error This change fixes the error message when Delve was unable to move the config. Previously returned a FileInfo object not the file path. * pkg/config: Remove check for stderr when printing error messages * pkg/config: Move success message for moving config to stderr This prevents the success message from being printed to stdout and breaking frontends. * pkg/config: Rename variable to be more descriptive

FindGoroutine can be slow when there are many goroutines running. This can not be fixed in the general case, however: 1. Instead of getting the entire list of goroutines at once just get a few at a time and return as soon as we find the one we want. 2. Since FindGoroutine is mostly called by ConvertEvalScope and users are more likely to request informations about a goroutine running on a thread, look within the threads first.

As specified in line dwarf/godwarf/type.go:507 the typeCache entry should always be set before recursive calls to readType to avoid infite recursion. Most code in readType already does this but some of the code added later to handle Go types was wrong. Fix this bug and also fix the String and Size methods of Type so that they handle recursive types "correctly" (i.e. they don't recur forever). No test is added for this since all legitimate uses of cyclical types were already handled correctly and the malformed types emitted by the go compiler will probably be removed in 1.12. See: https://github.com/golang/go/issues/29264 Fixes #1444

Some build environments (such as when building RPMs) enjoy symlinking things. This unfortunately causes our tests to fail as we record the path of fixtures and use that when looking up file:line information. However, the debug info in the binary records the original file location, not the location of the symlink.

The size of the TLS memory arena needs to be aligned to pointer sized boundaries on 86x64 architectures, otherwise some programs using cgo will not have the correct offset for the g struct. No tests because reproducing this problem depends on behavior of the GNU ld linker caused by unclear influences. Fixes #1428.
