Alasdair G Kergon	7f747a0d73	logging: add debug classes ... Add log/debug_classes to lvm.conf to allow debug messages to be classified and filtered at runtime. The dm_errno field is only used by log_error(), so I've redefined it for log_debug() messages to hold the message class. By default, all existing messages appear, but we can add categories that generate high volumes of data, such as logging all traffic to/from lvmetad.	2013-01-07 22:25:19 +00:00

Petr Rockai	99a304bc17	Optionally abort on internal errors (and leverage this option in the ... testsuite). (This is showing a problem in the pvmove test for me, so I expect the tests to start failing -- this needs to be fixed separately though.)	2009-11-30 17:17:11 +00:00
Dave Wysochanski	a0b1b1872e	Change default errno value to 0 (no error) and add prototypes in lvm.h ... Since we are using errno values, we should use '0' as a default value which indicates a non-error, rather than defining some made-up default value that is not defined in errno. If we need to deviate from errno values, this will most likely indicate a flaw in our design. Add prototypes for lvm_errno and lvm_errmsg inside lvm.h and provide a basic description of their function. This fixes a couple compile warnings.

Alasdair Kergon	9fac443591	Add log_errno to set a specific errno and replace log_error in due course.	2009-07-16 00:52:06 +00:00
Alasdair Kergon	d917192f00	Add lvm_errno and lvm_errmsg to liblvm to obtain failure information. ... Change create_toolcontext to still return an object if it fails part-way. Add EUNCLASSIFIED (-1) as the default LVM errno code.	2009-07-16 00:36:59 +00:00
Alasdair Kergon	d614646157	Store any errno and error messages issued while processing each command. ... (Enabled by default while we test it, but in due course we'll only store the error messages when we need to.)	2009-07-15 23:57:54 +00:00
Alasdair Kergon	a9cb6969b0	Add dm_log_with_errno and dm_log_with_errno_init, deprecating the old ... Change plog to use dm_log_with_errno unless deprecated dm_log_init was used. Rename plog macro to LOG_LINE and use in dm_dump_memory_debug.	2009-07-10 09:59:37 +00:00
