The issue is that we don't currently distinguish send "interrupt/ctrl-c" to target terminal vs "stop/pause" thread well; both cases go through "target_stop". And then, the native Linux backend (linux-nat.c) implements target_stop with SIGSTOP in non-stop mode, and SIGINT in all-stop mode. Since "maint set target-non-stop on" forces the backend to be always running in non-stop mode, even though the user-visible behavior is "set non-stop" is "off", "interrupt" causes a SIGSTOP instead of the SIGINT the test expects. Fix this by introducing a target_interrupt method to use in the "interrupt/ctrl-c" case, so "set non-stop off" can always work the same irrespective of "maint set target-non-stop on/off". I'm explictly considering changing the "set non-stop on" behavior as out of scope here. Most of the patch is an across-the-board rename of to_stop hook implementations to to_interrupt. The only targets where something more than a rename is being done are linux-nat.c and remote.c, which are the only targets that support async, and thus are the only ones the core side calls target_stop on. gdb/ChangeLog: 2015-08-07 Pedro Alves <palves@redhat.com> * darwin-nat.c (darwin_stop): Rename to ...

Use gdb_byte for bytes from the program being debugged. gdb_byte should be used for bytes from the program being debugged. We have many places using char or unsigned char instead all over the existing ports, and more ends up added over time due to copy/paste as new code is based on old code.

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.

remove pop_target This patch fixes the target double-close problem (PR remote/15266), and in the process removes pop_target entire (PR remote/15256). The first issue is that pop_target calls target_close. However, it then calls unpush_target, which also calls target_close. This means targets must be able to be closed twice. Not only is this strange, but it also directly contradicts the contract of to_xclose targets. (We currently have just a single such target, and it is never pushed; but I plan to add more, and so this latent bug is triggered.) The second issue is that it seems to me that calling pop_target is often unsafe. This is what cropped up in 15256, where the remote target assumed that it could pop_target -- but there was another target higher on the stack, leading to confusion. But, it is always just as easy to call unpush_target as it is to call pop_target; and it is also safer. So, removing pop_target seemed like an improvement. Finally, this adds an assertion to target_close to ensure that no currently-pushed target can be closed. Built and regtested on x86-64 Fedora 18; both natively and using the native-gdbserver board file.

The issue is that we don't currently distinguish send "interrupt/ctrl-c" to target terminal vs "stop/pause" thread well; both cases go through "target_stop". And then, the native Linux backend (linux-nat.c) implements target_stop with SIGSTOP in non-stop mode, and SIGINT in all-stop mode. Since "maint set target-non-stop on" forces the backend to be always running in non-stop mode, even though the user-visible behavior is "set non-stop" is "off", "interrupt" causes a SIGSTOP instead of the SIGINT the test expects. Fix this by introducing a target_interrupt method to use in the "interrupt/ctrl-c" case, so "set non-stop off" can always work the same irrespective of "maint set target-non-stop on/off". I'm explictly considering changing the "set non-stop on" behavior as out of scope here. Most of the patch is an across-the-board rename of to_stop hook implementations to to_interrupt. The only targets where something more than a rename is being done are linux-nat.c and remote.c, which are the only targets that support async, and thus are the only ones the core side calls target_stop on. gdb/ChangeLog: 2015-08-07 Pedro Alves <palves@redhat.com> * darwin-nat.c (darwin_stop): Rename to ...

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".

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 patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

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".

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".

The issue is that we don't currently distinguish send "interrupt/ctrl-c" to target terminal vs "stop/pause" thread well; both cases go through "target_stop". And then, the native Linux backend (linux-nat.c) implements target_stop with SIGSTOP in non-stop mode, and SIGINT in all-stop mode. Since "maint set target-non-stop on" forces the backend to be always running in non-stop mode, even though the user-visible behavior is "set non-stop" is "off", "interrupt" causes a SIGSTOP instead of the SIGINT the test expects. Fix this by introducing a target_interrupt method to use in the "interrupt/ctrl-c" case, so "set non-stop off" can always work the same irrespective of "maint set target-non-stop on/off". I'm explictly considering changing the "set non-stop on" behavior as out of scope here. Most of the patch is an across-the-board rename of to_stop hook implementations to to_interrupt. The only targets where something more than a rename is being done are linux-nat.c and remote.c, which are the only targets that support async, and thus are the only ones the core side calls target_stop on. gdb/ChangeLog: 2015-08-07 Pedro Alves <palves@redhat.com> * darwin-nat.c (darwin_stop): Rename to ...
