add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

fix regressions with target-async A patch in the target cleanup series caused a regression when using record with target-async. Version 4 of the patch is here: https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html The immediate problem is that record supplies to_can_async_p and to_is_async_p methods, but does not supply a to_async method. So, when target-async is set, record claims to support async -- but if the underlying target does not support async, then the to_async method call will end up in that method's default implementation, namely tcomplain. This worked previously because the record target used to provide a to_async method; one that (erroneously, only at push time) checked the other members of the target stack, and then simply dropped to_async calls in the "does not implement async" case. My first thought was to simply drop tcomplain as the default for to_async. This works, but Pedro pointed out that the only reason record has to supply to_can_async_p and to_is_async_p is that these default to using the find_default_run_target machinery -- and these defaults are only needed by "run" and "attach". So, a nicer solution presents itself: change run and attach to explicitly call into the default run target when needed; and change to_is_async_p and to_can_async_p to default to "return 0". This makes the target stack simpler to use and lets us remove the method implementations from record. This is also in harmony with other plans for the target stack; namely trying to reduce the impact of find_default_run_target. This approach makes it clear that find_default_is_async_p is not needed -- it is asking whether a target that may not even be pushed is actually async, which seems like a nonsensical question. While an improvement, this approach proved to introduce the same bug when using the core target. Looking a bit deeper, the issue is that code in "attach" and "run" may need to use either the current target stack or the default run target -- but different calls into the target API in those functions could wind up querying different targets. This new patch makes the target to use more explicit in "run" and "attach". Then these commands explicitly make the needed calls against that target. This ensures that a single target is used for all relevant operations. This lets us remove a couple find_default_* functions from various targets, including the dummy target. I think this is a decent understandability improvement. One issue I see with this patch is that the new calls in "run" and "attach" are not very much like the rest of the target API. I think fundamentally this is due to bad factoring in the target API, which may need to be fixed for multi-target. Tackling that seemed ambitious for a regression fix. While working on this I noticed that there don't seem to be any test cases that involve both target-async and record, so this patch changes break-precsave.exp to add some. It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

fix regressions with target-async A patch in the target cleanup series caused a regression when using record with target-async. Version 4 of the patch is here: https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html The immediate problem is that record supplies to_can_async_p and to_is_async_p methods, but does not supply a to_async method. So, when target-async is set, record claims to support async -- but if the underlying target does not support async, then the to_async method call will end up in that method's default implementation, namely tcomplain. This worked previously because the record target used to provide a to_async method; one that (erroneously, only at push time) checked the other members of the target stack, and then simply dropped to_async calls in the "does not implement async" case. My first thought was to simply drop tcomplain as the default for to_async. This works, but Pedro pointed out that the only reason record has to supply to_can_async_p and to_is_async_p is that these default to using the find_default_run_target machinery -- and these defaults are only needed by "run" and "attach". So, a nicer solution presents itself: change run and attach to explicitly call into the default run target when needed; and change to_is_async_p and to_can_async_p to default to "return 0". This makes the target stack simpler to use and lets us remove the method implementations from record. This is also in harmony with other plans for the target stack; namely trying to reduce the impact of find_default_run_target. This approach makes it clear that find_default_is_async_p is not needed -- it is asking whether a target that may not even be pushed is actually async, which seems like a nonsensical question. While an improvement, this approach proved to introduce the same bug when using the core target. Looking a bit deeper, the issue is that code in "attach" and "run" may need to use either the current target stack or the default run target -- but different calls into the target API in those functions could wind up querying different targets. This new patch makes the target to use more explicit in "run" and "attach". Then these commands explicitly make the needed calls against that target. This ensures that a single target is used for all relevant operations. This lets us remove a couple find_default_* functions from various targets, including the dummy target. I think this is a decent understandability improvement. One issue I see with this patch is that the new calls in "run" and "attach" are not very much like the rest of the target API. I think fundamentally this is due to bad factoring in the target API, which may need to be fixed for multi-target. Tackling that seemed ambitious for a regression fix. While working on this I noticed that there don't seem to be any test cases that involve both target-async and record, so this patch changes break-precsave.exp to add some. It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target.

fix regressions with target-async A patch in the target cleanup series caused a regression when using record with target-async. Version 4 of the patch is here: https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html The immediate problem is that record supplies to_can_async_p and to_is_async_p methods, but does not supply a to_async method. So, when target-async is set, record claims to support async -- but if the underlying target does not support async, then the to_async method call will end up in that method's default implementation, namely tcomplain. This worked previously because the record target used to provide a to_async method; one that (erroneously, only at push time) checked the other members of the target stack, and then simply dropped to_async calls in the "does not implement async" case. My first thought was to simply drop tcomplain as the default for to_async. This works, but Pedro pointed out that the only reason record has to supply to_can_async_p and to_is_async_p is that these default to using the find_default_run_target machinery -- and these defaults are only needed by "run" and "attach". So, a nicer solution presents itself: change run and attach to explicitly call into the default run target when needed; and change to_is_async_p and to_can_async_p to default to "return 0". This makes the target stack simpler to use and lets us remove the method implementations from record. This is also in harmony with other plans for the target stack; namely trying to reduce the impact of find_default_run_target. This approach makes it clear that find_default_is_async_p is not needed -- it is asking whether a target that may not even be pushed is actually async, which seems like a nonsensical question. While an improvement, this approach proved to introduce the same bug when using the core target. Looking a bit deeper, the issue is that code in "attach" and "run" may need to use either the current target stack or the default run target -- but different calls into the target API in those functions could wind up querying different targets. This new patch makes the target to use more explicit in "run" and "attach". Then these commands explicitly make the needed calls against that target. This ensures that a single target is used for all relevant operations. This lets us remove a couple find_default_* functions from various targets, including the dummy target. I think this is a decent understandability improvement. One issue I see with this patch is that the new calls in "run" and "attach" are not very much like the rest of the target API. I think fundamentally this is due to bad factoring in the target API, which may need to be fixed for multi-target. Tackling that seemed ambitious for a regression fix. While working on this I noticed that there don't seem to be any test cases that involve both target-async and record, so this patch changes break-precsave.exp to add some. It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target.

fix regressions with target-async A patch in the target cleanup series caused a regression when using record with target-async. Version 4 of the patch is here: https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html The immediate problem is that record supplies to_can_async_p and to_is_async_p methods, but does not supply a to_async method. So, when target-async is set, record claims to support async -- but if the underlying target does not support async, then the to_async method call will end up in that method's default implementation, namely tcomplain. This worked previously because the record target used to provide a to_async method; one that (erroneously, only at push time) checked the other members of the target stack, and then simply dropped to_async calls in the "does not implement async" case. My first thought was to simply drop tcomplain as the default for to_async. This works, but Pedro pointed out that the only reason record has to supply to_can_async_p and to_is_async_p is that these default to using the find_default_run_target machinery -- and these defaults are only needed by "run" and "attach". So, a nicer solution presents itself: change run and attach to explicitly call into the default run target when needed; and change to_is_async_p and to_can_async_p to default to "return 0". This makes the target stack simpler to use and lets us remove the method implementations from record. This is also in harmony with other plans for the target stack; namely trying to reduce the impact of find_default_run_target. This approach makes it clear that find_default_is_async_p is not needed -- it is asking whether a target that may not even be pushed is actually async, which seems like a nonsensical question. While an improvement, this approach proved to introduce the same bug when using the core target. Looking a bit deeper, the issue is that code in "attach" and "run" may need to use either the current target stack or the default run target -- but different calls into the target API in those functions could wind up querying different targets. This new patch makes the target to use more explicit in "run" and "attach". Then these commands explicitly make the needed calls against that target. This ensures that a single target is used for all relevant operations. This lets us remove a couple find_default_* functions from various targets, including the dummy target. I think this is a decent understandability improvement. One issue I see with this patch is that the new calls in "run" and "attach" are not very much like the rest of the target API. I think fundamentally this is due to bad factoring in the target API, which may need to be fixed for multi-target. Tackling that seemed ambitious for a regression fix. While working on this I noticed that there don't seem to be any test cases that involve both target-async and record, so this patch changes break-precsave.exp to add some. It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

Make compare-sections work against all targets; add compare-sections [-r] tests. This does two things: 1. Adds a test. Recently compare-sections got a new "-r" switch, but given no test existed for compare-sections, the patch was allowed in with no testsuite addition. This now adds a test for both compare-sections and compare-sections -r. 2. Makes the compare-sections command work against all targets. Currently, compare-sections only works with remote targets, and only those that support the qCRC packet. The patch makes it so that if the target doesn't support accelerating memory verification, then GDB falls back to comparing memory itself. This is of course slower, but it's better than nothing, IMO. While testing against extended-remote GDBserver I noticed that we send the qCRC request to the target if we're connected, but not yet running a program. That can't work of course -- the patch fixes that. This all also goes in the direction of bridging the local/remote parity gap. I didn't decouple 1. from 2., because that would mean that the test would need to handle the case of the target not supporting the command. Tested on x86_64 Fedora 17, native, remote GDBserver, and extended-remote GDBserver. I also hack-disabled qCRC support to make sure the fallback paths in remote.c work. gdb/doc/ 2014-05-20 Pedro Alves <palves@redhat.com> * gdb.texinfo (Memory) <compare-sections>: Generalize comments to not be remote specific.
