mdoc: order prologue macros consistently by Dd/Dt/Os

2010-04-14T19:08:06Z

Although groff_mdoc(7) gives another impression, this is the ordering most widely used and also required by mdocml/mandoc. Reviewed by: ru Approved by: philip, ed (mentors)

Remove utmpx stub from libulog.

2010-01-13T18:53:06Z

I'm not increasing the shlib major version for this, because not a single application outside the base system should have used these functions in such a short timespan. Rewrite ulog_login(3) and ulog_logout(3) to build on top of the utmpx implementation in libc.

Implement .

2010-01-13T17:29:55Z

The utmpx interface is the standardized interface of the user accounting database. The standard only defines a subset of the functions that were present in System V-like systems. I'd like to highlight some of the traits my implementation has: - The standard allows the on-disk format to be different than the in-memory representation (struct utmpx). Most operating systems don't do this, but we do. This allows us to keep our ABI more stable, while giving us the opportunity to modify the on-disk format. It also allows us to use a common file format across different architectures (i.e. byte ordering). - Our implementation of pututxline() also updates wtmp and lastlog (now called utx.log and utx.lastlogin). This means the databases are more likely to be in sync. - Care must be taken that our implementation discard any fields that are not applicable. For example, our DEAD_PROCESS records do not hold a TTY name. Just a time stamp, a record identifier and a process identifier. It also guarantees that strings (ut_host, ut_line and ut_user) are null terminated. ut_id is obviously not null terminated, because it's not a string. - The API and its behaviour should be conformant to POSIX, but there may be things that slightly deviate from the standard. This implementation uses separate file descriptors when writing to the log files. It also doesn't use getutxid() to search for a field to overwrite. It uses an allocation strategy similar to getutxid(), but prevents DEAD_PROCESS records from accumulating. Make sure libulog doesn't overwrite the manpages shipped with our C library. Also keep the symbol list in Symbol.map sorted. I'll bump __FreeBSD_version later this evening. I first want to convert everything to and get rid of .

Build lib/ with WARNS=6 by default.

2010-01-02T09:58:07Z

Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and lower it when needed. I'm setting WARNS?=0 for secure/. It seems secure/ includes the Makefile.inc provided by lib/. I'm not going to touch that directory. Most of the code there is contributed anyway.

Parse DEAD_PROCESS entries properly.

2009-12-27T22:26:29Z

The TTY line name should always be set for DEAD_PROCESS entries right now. When we parse a clean utmp entry, we don't want to interpret it as a DEAD_PROCESS entry if the TTY has never been used yet.

Several refinements to libulog's API.

2009-12-26T22:36:05Z

- Only set the fields in the ulog_utmpx structure that are valid for the command in question. This means that strings like "shutdown" or "~" are not visible to the user anymore. - Rename UTXF_* to UTXI_*, indicating the indexation, instead of using the `antique' filename. If we ever get rid of utmp, it makes little sense calling it by its old name.

Don't corrupt logout entries in utmp files.

2009-12-25T20:04:36Z

An older version of the code used a structure on the stack, instead of a pointer to the structure. It looks like I didn't adjust the parameters of the write(2) call, causing the first four/eight bytes of the entry to be corrupted, instead of writing the entire entry to disk.

The hostname passed to ulog_login(3) may be optional.

Don't trip on a null pointer being passed to this function when performing a local login. Noticed by: dougb
