2016-10-05trans/crash: Fix setting core file template at runtime.Justus Winter
* 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'.
2016-10-05trans/crash: Use empty core file templates to disable the feature.Justus Winter
* trans/crash.c (parse_opt): Use empty core file templates to disable the feature.
2016-10-05Avoid fatal error handling in option parsers.Justus Winter
* 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.
2016-08-09trans/crash: core file name templatesJustus Winter
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.
2016-06-07trans/crash: fix blunderJustus Winter
* trans/crash.c (S_crash_dump_task): Fix error handling.
2016-06-04trans/crash: fix resource leaksJustus Winter
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'.
2016-05-03Fix buildSamuel Thibault
* trans/crash.c: Include <assert.h>.
2016-02-21trans/crash: fix suspending taskJustus Winter
* trans/crash.c (S_crash_dump_task): Fix looking up 'user_proc'.
2015-09-27trans/crash: convert to trivfs dynamic classes and bucketsJustus Winter
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.
