[issue12619] Automatically regenerate platform-specific modules

[STINNER Victor]

STINNER Victor <victor.stinner at haypocalc.com> added the comment:

For Freevo: yes, it uses the CDROM module. But this module doesn't look to be perfect because Freevo has a fallback for FreeBSD and another for... Linux (because of missing CDROM.CDROM_DRIVE_STATUS?):
-----------------------------
try:
    from CDROM import *
    # test if CDROM_DRIVE_STATUS is there
    # (for some strange reason, this is missing sometimes)
    CDROM_DRIVE_STATUS
except:
    if os.uname()[0] == 'FreeBSD':
        # FreeBSD ioctls - there is no CDROM.py...
        CDIOCEJECT = 0x20006318
        CDIOCCLOSE = 0x2000631c
        CDIOREADTOCENTRYS = 0xc0086305
        CD_LBA_FORMAT = 1
        CD_MSF_FORMAT = 2
        CDS_NO_DISC = 1
        CDS_DISC_OK = 4
    else:
        # see linux/cdrom.h and Documentation/ioctl/cdrom.txt
        CDROMEJECT           = 0x5309
        CDROM_GET_CAPABILITY = 0x5331
        CDROMCLOSETRAY       = 0x5319  # pendant of CDROMEJECT
        CDROM_SET_OPTIONS    = 0x5320  # Set behavior options
        CDROM_CLEAR_OPTIONS  = 0x5321  # Clear behavior options
        CDROM_SELECT_SPEED   = 0x5322  # Set the CD-ROM speed
        CDROM_SELECT_DISC    = 0x5323  # Select disc (for juke-boxes)
        CDROM_MEDIA_CHANGED  = 0x5325  # Check is media changed
        CDROM_DRIVE_STATUS   = 0x5326  # Get tray position, etc.
        CDROM_DISC_STATUS    = 0x5327  # Get disc type, etc.
        CDROM_CHANGER_NSLOTS = 0x5328  # Get number of slots
        CDROM_LOCKDOOR       = 0x5329  # lock or unlock door
        CDROM_DEBUG          = 0x5330  # Turn debug messages on/off
        CDROM_GET_CAPABILITY = 0x5331  # get capabilities
        # CDROM_DRIVE_STATUS
        CDS_NO_INFO = 0
        CDS_NO_DISC = 1
        CDS_TRAY_OPEN = 2
        CDS_DRIVE_NOT_READY = 3
        CDS_DISC_OK = 4
        # capability flags
        CDC_CLOSE_TRAY       = 0x1     # caddy systems _can't_ close
        CDC_OPEN_TRAY        = 0x2     # but _can_ eject.
        CDC_LOCK             = 0x4     # disable manual eject
        CDC_SELECT_SPEED     = 0x8     # programmable speed
        CDC_SELECT_DISC      = 0x10    # select disc from juke-box
CDC_MO_DRIVE         = 0x40000
CDC_MRW              = 0x80000
CDC_MRW_W            = 0x100000
CDC_RAM              = 0x200000
# CDROM_DISC_STATUS
CDS_AUDIO = 100
CDS_DATA_1 = 101
CDS_DATA_2 = 102
CDS_XA_2_1 = 103
CDS_XA_2_2 = 104
CDS_MIXED = 105
-----------------------------

So Freevo does stil work if we remove the CDROM module. I still think that the Python standard library is not the right place for such constants. A third party module providing an API would be a better idea.

socket.SO_PEERCRED has been added to Python 3.3 by c64216addd7f:

"Add support for the send/recvmsg API to the socket module. Patch by David Watson and Heiko Wundram. (Closes #6560)"

socket.SO_PEERCRED is not listed in socket documentation.

socket has no SO_BINDTODEVICE constant yet.

RTLD_NOW, RTLD_GLOBAL and RTLD_LAZY will added to the posix module if my issue #13226 is accepted.
