* trans/crash.c (corefile_template_lock): New variable.
(S_crash_dump_task): Serialize access to 'corefile_template'.
(parse_opt): Likewise. Also strdup the template.
(trivfs_append_args): Serialize access to 'corefile_template'.
|
|
* trans/crash.c (parse_opt): Use empty core file templates to disable
the feature.
|
|
* trans/crash.c (parse_opt): Avoid 'error' in favor of the appropriate
argp error reporting mechanism.
* trans/remap.c (parse_opt): Likewise.
* utils/msgids.c (parse_opt): Likewise.

Add an option to specify a template used to construct core file names.
This way core files can be collected at a predictable central
location.
* hurd/crash.defs (crash_dump_task): Return EEXIST if the core file
has been written elsewhere.
* trans/crash.c (corefile_template): New variable.
(template_valid): New function.
(template_make_file_name): Likewise.
(S_crash_dump_task): Use the template to construct a name, open the
file, and write the core dump there instead of the handle provided by
the caller.
(argp_option): New option.
(doc): Document the format.
(parse_opt): Handle new option
(trivfs_append_args): Likewise.

* trans/crash.c (S_crash_dump_task): Fix error handling.

Previously, 'task', 'core_file', and 'ctty_id' were not deallocated if
crash was configured to write core files, and 'ctty_id' was leaked if
the crashing task was suspended. This lead to resources not being
released in the kernel, the filesystem, and the terminal subsystem,
and could very well be responsible for making the Debian/Hurd shutdown
hang.
* trans/crash.c (S_crash_dump_task): Properly deallocate 'task',
'core_file', and 'ctty_id'.
|
|
* trans/crash.c: Include <assert.h>.
|
|
* trans/crash.c (S_crash_dump_task): Fix looking up 'user_proc'.

libtrivfs contains two ways of managing more than one port class and
bucket. There is the old way of using a statically allocated array
with explicit length, and the new way with dynamically allocated
vectors.
Converting all users to the new way of handling multiple classes
and/or buckets, we can simplify the code in libtrivfs. In many cases,
the code will be simpler and more expressive for the user.
This also fixes a mild bug. The classes and buckets given to
`trivfs_startup' end up in the dynamic vectors too, making the object
lookup code use the more complicated code path.
* trans/crash.c: Convert to dynamic classes and buckets.

* crash.c (S_msg_startup_dosync): Remove function.

* crash.c: Correct the usage of the argp documentation string.

* symlink.c (S_fsys_getroot, S_fsys_getfile): u_int -> size_t
* streamio.c (device_open_reply): size_t -> int for dev_status_t
* crash.c (S_msg_report_wait): int -> mach_msg_id_t
(S_crash_dump_task): int -> integer_t
|

* streamio.c (device_open_reply): size_t -> int for dev_status_t
* crash.c (S_msg_report_wait): int -> mach_msg_id_t

(struct crasher): New member `core_limit'.
(dead_crasher): Pass C->core_limit to dump_core.
(S_crash_dump_task): Set C->core_limit, to (off_t) -1 for now.
(dump_core): Function removed; now ../exec/elfcore.c defines it.
* Makefile (OBJS, crash): Add elfcore.o.
(elfcore.c): vpath decl to find this in $(top_srcdir)/exec.
