| 1 | Changes made to lpr/lpd system |
|---|
| 2 | |
|---|
| 3 | Starred (*) items should get propagated back to Berkeley. |
|---|
| 4 | |
|---|
| 5 | printjob.c Changed abortpr so that the lock file is closed immediately, |
|---|
| 6 | so that other lpd's can start printing other files. Also, 30 |
|---|
| 7 | seconds after the output filters receive a SIGTERM, if |
|---|
| 8 | they have not exited yet, abortpr sends them a SIGKILL |
|---|
| 9 | to wipe them out. |
|---|
| 10 | [tytso:19890114.2255EST]* |
|---|
| 11 | |
|---|
| 12 | lpd.c Changed MAX_ATHENA_SUBNET to be 18.141 instead of 18.92, |
|---|
| 13 | so that mit-pika is included part of the "athena |
|---|
| 14 | network", so that a hostname check is not necessary. |
|---|
| 15 | We may want to dike out this code completely, and just |
|---|
| 16 | let anybody in 18.*.*.* to print a file.... since anybody |
|---|
| 17 | whose IP address resolves into a hostname can print |
|---|
| 18 | a file anyway.... |
|---|
| 19 | [tytso:19890114.2228EST] |
|---|
| 20 | |
|---|
| 21 | lpd.c Instead of using the version of startdaemon found in |
|---|
| 22 | startdaemon.c, which opens a connection to lpd and sends |
|---|
| 23 | it a command to start a printer daemon, use a version |
|---|
| 24 | of startdaemon that forks a child which becomes the printer |
|---|
| 25 | daemon, since a copy of lpd is running anyway.... |
|---|
| 26 | [tytso:19890114.2106EST]* |
|---|
| 27 | |
|---|
| 28 | s_displayq.c Instead of printing: |
|---|
| 29 | |
|---|
| 30 | "Printer daemon %d does not exist yet, try again in a few minutes", |
|---|
| 31 | |
|---|
| 32 | (This message is bogus, since it got the pid from |
|---|
| 33 | the lock file, which meant that the daemon must |
|---|
| 34 | have existed at one time to write the lock file |
|---|
| 35 | in the first place. Lose, lose) |
|---|
| 36 | s_displayq attempts to start a new printer daemon. |
|---|
| 37 | If it succeeds, it prints: |
|---|
| 38 | |
|---|
| 39 | "Printer daemon %d does not exist; restarting a new one" |
|---|
| 40 | |
|---|
| 41 | If it fails, it prints: |
|---|
| 42 | |
|---|
| 43 | "Printer daemon $d does not exist; could not start a new one!" |
|---|
| 44 | |
|---|
| 45 | [tytso:19890113.2223EST]* |
|---|
| 46 | |
|---|
| 47 | |
|---|
| 48 | rmjob.c Each control file in the spool directory is locked by |
|---|
| 49 | printjob.c by printjob while it is being processed, and locked by |
|---|
| 50 | rmjob before it is removed. If printjob attempts to |
|---|
| 51 | lock a control file and it is already locked, it defers |
|---|
| 52 | processing the job until later (probably when it checks |
|---|
| 53 | again, it will be gone.) If rmjob attempts to lock a |
|---|
| 54 | control file and it is already locked, it trys to kill |
|---|
| 55 | the the currently active line printer daemon. This fixes |
|---|
| 56 | a race condition which caused the lpd to hang until |
|---|
| 57 | it was forcibly restarted. |
|---|
| 58 | [tytso:19890113.2107EST]* |
|---|
| 59 | |
|---|
| 60 | (source Files in /source/4.3/usr.lib/lpr and in /source/4.3/ucb/lpr |
|---|
| 61 | directory) were merged. lpr, lpq, and lprm do not spool files into |
|---|
| 62 | the spool directory but instead send files directly to |
|---|
| 63 | lpd via the network. s_lpr, s_lpq, and s_lprm are the |
|---|
| 64 | original versions which do access to the spool directory. |
|---|
