Change detach_breakpoints to take a ptid instead of a pid Before this change, detach_breakpoints would take a pid, and then set inferior_ptid to a ptid that it constructs using pid_to_ptid (pid). Unfortunately, this ptid is not necessarily valid. Consider for instance the case of ia64-hpux, where ttrace refuses a register-read operation if the LWP is not provided. This problems shows up when GDB is trying to handle fork events. Assuming GDB is configured to follow the parent, GDB will try to detach from the child. But before doing so, it needs to remove all breakpoints inside that child. On ia64, this involves reading inferior (the child's) memory. And on ia64-hpux, reading memory requires us to read the bsp and bspstore registers, in order to determine where that memory is relative to the value of those registers, and thus to determine which ttrace operation to use in order to fetch that memory (see ia64_hpux_xfer_memory). This patch therefore changes detach_breakpoints to take a ptid instead of a pid, and then updates all callers. One of the consequences of this patch is that it trips an assert on GNU/Linux targets. But this assert appears to have not actual purpose, and is thus removed. gdb/ChangeLog: * breakpoint.h (detach_breakpoints): pid parameter is now a ptid. * breakpoint.c (detach_breakpoints): Change pid parameter into a ptid. Adjust code accordingly. * infrun.c (handle_inferior_event): Delete variable child_pid. Update call to detach_breakpoints to pass the child ptid for fork events. * linux-nat.c (linux_nat_iterate_watchpoint_lwps): Remove assert that inferior_ptid's lwp is zero.

Change detach_breakpoints to take a ptid instead of a pid Before this change, detach_breakpoints would take a pid, and then set inferior_ptid to a ptid that it constructs using pid_to_ptid (pid). Unfortunately, this ptid is not necessarily valid. Consider for instance the case of ia64-hpux, where ttrace refuses a register-read operation if the LWP is not provided. This problems shows up when GDB is trying to handle fork events. Assuming GDB is configured to follow the parent, GDB will try to detach from the child. But before doing so, it needs to remove all breakpoints inside that child. On ia64, this involves reading inferior (the child's) memory.

Allow making GDB not automatically connect to the native target. Sometimes it's useful to be able to disable the automatic connection to the native target. E.g., sometimes GDB disconnects from the extended-remote target I was debugging, without me noticing it, and then I do "run". That starts the program locally, and only after a little head scratch session do I figure out the program is running locally instead of remotely as intended. Same thing with "attach", "info os", etc. With the patch, we now can have this instead: (gdb) set auto-connect-native-target off (gdb) target extended-remote :9999 ... *gdb disconnects* (gdb) run Don't know how to run. Try "help target". To still be able to connect to the native target with auto-connect-native-target set to off, I've made "target native" work instead of erroring out as today. Before: (gdb) target native Use the "run" command to start a native process. After: (gdb) target native Done. Use the "run" command to start a process. (gdb) maint print target-stack The current target stack is: - native (Native process) - exec (Local exec file) - None (None) (gdb) run Starting program: ./a.out ... I've also wanted this for the testsuite, when running against the native-extended-gdbserver.exp board (runs against gdbserver in extended-remote mode). With a non-native-target board, it's always a bug to launch a program with the native target. Turns out we still have one such case this patch catches: (gdb) break main Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138. (gdb) run Don't know how to run. Try "help target". (gdb) FAIL: gdb.base/corefile.exp: run: with core On the patch itself, probably the least obvious bit is the need to go through all targets, and move the unpush_target call to after the generic_mourn_inferior call instead of before. This is what inf-ptrace.c does too, ever since multi-process support was added. The reason inf-ptrace.c does things in that order is that in the current multi-process/single-target model, we shouldn't unpush the target if there are still other live inferiors being debugged. The check for that is "have_inferiors ()" (a misnomer nowadays...), which does: have_inferiors (void) { for (inf = inferior_list; inf; inf = inf->next) if (inf->pid != 0) return 1; It's generic_mourn_inferior that ends up clearing inf->pid, so we need to call it before the have_inferiors check. To make all native targets behave the same WRT to explicit "target native", I've added an inf_child_maybe_unpush_target function that targets call instead of calling unpush_target directly, and as that includes the have_inferiors check, I needed to adjust the targets. Tested on x86_64 Fedora 20, native, and also with the extended-gdbserver board. Confirmed a cross build of djgpp gdb still builds. Smoke tested a cross build of Windows gdb under Wine.

Allow making GDB not automatically connect to the native target. Sometimes it's useful to be able to disable the automatic connection to the native target. E.g., sometimes GDB disconnects from the extended-remote target I was debugging, without me noticing it, and then I do "run". That starts the program locally, and only after a little head scratch session do I figure out the program is running locally instead of remotely as intended. Same thing with "attach", "info os", etc. With the patch, we now can have this instead: (gdb) set auto-connect-native-target off (gdb) target extended-remote :9999 ... *gdb disconnects* (gdb) run Don't know how to run. Try "help target". To still be able to connect to the native target with auto-connect-native-target set to off, I've made "target native" work instead of erroring out as today. Before: (gdb) target native Use the "run" command to start a native process. After: (gdb) target native Done. Use the "run" command to start a process. (gdb) maint print target-stack The current target stack is: - native (Native process) - exec (Local exec file) - None (None) (gdb) run Starting program: ./a.out ... I've also wanted this for the testsuite, when running against the native-extended-gdbserver.exp board (runs against gdbserver in extended-remote mode). With a non-native-target board, it's always a bug to launch a program with the native target. Turns out we still have one such case this patch catches: (gdb) break main Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138. (gdb) run Don't know how to run. Try "help target". (gdb) FAIL: gdb.base/corefile.exp: run: with core On the patch itself, probably the least obvious bit is the need to go through all targets, and move the unpush_target call to after the generic_mourn_inferior call instead of before. This is what inf-ptrace.c does too, ever since multi-process support was added. The reason inf-ptrace.c does things in that order is that in the current multi-process/single-target model, we shouldn't unpush the target if there are still other live inferiors being debugged. The check for that is "have_inferiors ()" (a misnomer nowadays...), which does: have_inferiors (void) { for (inf = inferior_list; inf; inf = inf->next) if (inf->pid != 0) return 1; It's generic_mourn_inferior that ends up clearing inf->pid, so we need to call it before the have_inferiors check. To make all native targets behave the same WRT to explicit "target native", I've added an inf_child_maybe_unpush_target function that targets call instead of calling unpush_target directly, and as that includes the have_inferiors check, I needed to adjust the targets. Tested on x86_64 Fedora 20, native, and also with the extended-gdbserver board. Confirmed a cross build of djgpp gdb still builds. Smoke tested a cross build of Windows gdb under Wine.

Allow making GDB not automatically connect to the native target. Sometimes it's useful to be able to disable the automatic connection to the native target. E.g., sometimes GDB disconnects from the extended-remote target I was debugging, without me noticing it, and then I do "run". That starts the program locally, and only after a little head scratch session do I figure out the program is running locally instead of remotely as intended. Same thing with "attach", "info os", etc. With the patch, we now can have this instead: (gdb) set auto-connect-native-target off (gdb) target extended-remote :9999 ... *gdb disconnects* (gdb) run Don't know how to run. Try "help target". To still be able to connect to the native target with auto-connect-native-target set to off, I've made "target native" work instead of erroring out as today. Before: (gdb) target native Use the "run" command to start a native process. After: (gdb) target native Done. Use the "run" command to start a process. (gdb) maint print target-stack The current target stack is: - native (Native process) - exec (Local exec file) - None (None) (gdb) run Starting program: ./a.out ... I've also wanted this for the testsuite, when running against the native-extended-gdbserver.exp board (runs against gdbserver in extended-remote mode). With a non-native-target board, it's always a bug to launch a program with the native target. Turns out we still have one such case this patch catches: (gdb) break main Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138. (gdb) run Don't know how to run. Try "help target". (gdb) FAIL: gdb.base/corefile.exp: run: with core On the patch itself, probably the least obvious bit is the need to go through all targets, and move the unpush_target call to after the generic_mourn_inferior call instead of before. This is what inf-ptrace.c does too, ever since multi-process support was added. The reason inf-ptrace.c does things in that order is that in the current multi-process/single-target model, we shouldn't unpush the target if there are still other live inferiors being debugged. The check for that is "have_inferiors ()" (a misnomer nowadays...), which does: have_inferiors (void) { for (inf = inferior_list; inf; inf = inf->next) if (inf->pid != 0) return 1; It's generic_mourn_inferior that ends up clearing inf->pid, so we need to call it before the have_inferiors check. To make all native targets behave the same WRT to explicit "target native", I've added an inf_child_maybe_unpush_target function that targets call instead of calling unpush_target directly, and as that includes the have_inferiors check, I needed to adjust the targets. Tested on x86_64 Fedora 20, native, and also with the extended-gdbserver board. Confirmed a cross build of djgpp gdb still builds. Smoke tested a cross build of Windows gdb under Wine.

constify to_detach This patch constifies the target_ops method to_detach. This is a small cleanup, but also, I think, a bug-prevention fix, since gdb already acts as if the "args" argument here was const. In particular, top.c:quit_force calls kill_or_detach via iterate_over_inferiors. kill_or_detach calls target_detach, passing the same argument each time. So, if one of these methods was not const-correct, then kill_or_detach would change its behavior in a strange way. I could not build every target I modified in this patch. I've inspected them all by hand, though. Many targets do not use the "args" parameter; a couple pass it to atoi; and a few pass it on to the to_detach method of the target beneath. The only code that required a real change was in linux-nat.c, and that only needed the introduction of a temporary variable for const-correctness. 2013-11-08 Tom Tromey <tromey@redhat.com> * aix-thread.c (aix_thread_detach): Update. * corelow.c (core_detach): Update. * darwin-nat.c (darwin_detach): Update. * dec-thread.c (dec_thread_detach): Update. * gnu-nat.c (gnu_detach): Update. * go32-nat.c (go32_detach): Update. * inf-ptrace.c (inf_ptrace_detach): Update. * inf-ttrace.c (inf_ttrace_detach): Update. * linux-fork.c (linux_fork_detach): Update. * linux-fork.h (linux_fork_detach): Update. * linux-nat.c (linux_nat_detach): Update.

Allow making GDB not automatically connect to the native target. Sometimes it's useful to be able to disable the automatic connection to the native target. E.g., sometimes GDB disconnects from the extended-remote target I was debugging, without me noticing it, and then I do "run". That starts the program locally, and only after a little head scratch session do I figure out the program is running locally instead of remotely as intended. Same thing with "attach", "info os", etc. With the patch, we now can have this instead: (gdb) set auto-connect-native-target off (gdb) target extended-remote :9999 ... *gdb disconnects* (gdb) run Don't know how to run.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0".

This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.
