  • be11235ab   env: Hide '.' variables in env print by default ... Browse Code »

    When printing all variables with env print, don't print variables that
    begin with '.'. If env print is called with a '-a' switch, then
    include variables that begin with '.' (just like the ls command).

    Variables printed explicitly will be printed even without the -a.

    Cleanup the env_nvram.c checkpatch warnings, errors and coding style.
    There are 2 wanring left about the extern used in c file:
    WARNING: externs should be avoided in .c files
    #53: FILE: env_nvram.c:53:
    +extern void *nvram_read(void *dest, const long src, size_t count);

    WARNING: externs should be avoided in .c files
    #54: FILE: env_nvram.c:54:
    +extern void nvram_write(long dest, const void *src, size_t count);

    total: 0 errors, 2 warnings, 138 lines checked

    There is no common nvram header file to use instead of the externs.

  • 37f2fe747   env: allow to export only selected variables ... Browse Code »

    New syntax:
    env export [-t | -b | -c] [-s size] addr [var ...]

    With this change it is possible to provide a list of variables names
    that shall be exported. Whenno arguments are given, the whole
    environment gets exported.

    NOTE: The new handling of the "size" argument means a change to the
    user API.

  • 2eb1573f0   hashtable: drop all non-reentrant versions ... Browse Code »

    The non-reentrant versions of the hashtable functions operate on a single
    shared hashtable. So if two different people try using these funcs for
    two different purposes, they'll cause problems for the other.

    Avoid this by converting all existing hashtable consumers over to the
    reentrant versions and then punting the non-reentrant ones.

  • ea882baf9   New implementation for internal handling of environment variables. ... Browse Code »

    Motivation:

    * Old environment code used a pessimizing implementation:
    - variable lookup used linear search => slow
    - changed/added variables were added at the end, i. e. most
    frequently used variables had the slowest access times => slow
    - each setenv() would calculate the CRC32 checksum over the whole
    environment block => slow
    * "redundant" envrionment was locked down to two copies
    * No easy way to implement features like "reset to factory defaults",
    or to select one out of several pre-defined (previously saved) sets
    of environment settings ("profiles")
    * No easy way to import or export environment settings

    ======================================================================

    API Changes:

    - Variable names starting with '#' are no longer allowed

    I didn't find any such variable names being used; it is highly
    recommended to follow standard conventions and start variable names
    with an alphanumeric character

    - "printenv" will now print a backslash at the end of all but the last
    lines of a multi-line variable value.

    Multi-line variables have never been formally defined, allthough
    there is no reason not to use them. Now we define rules how to deal
    with them, allowing for import and export.

    - Function forceenv() and the related code in saveenv() was removed.
    At the moment this is causing build problems for the only user of
    this code (schmoogie - which has no entry in MAINTAINERS); may be
    fixed later by implementing the "env set -f" feature.

    Inconsistencies:

    - "printenv" will '\\'-escape the '\n' in multi-line variables, while
    "printenv var" will not do that.

    ======================================================================

    Advantages:

    - "printenv" output much better readable (sorted)
    - faster!
    - extendable (additional variable properties can be added)
    - new, powerful features like "factory reset" or easy switching
    between several different environment settings ("profiles")

    Disadvantages:

    - Image size grows by typically 5...7 KiB (might shrink a bit again on
    systems with redundant environment with a following patch series)

    ======================================================================

    Implemented:

    - env command with subcommands:

    - env print [arg ...]

    same as "printenv": print environment

    - env set [-f] name [arg ...]

    same as "setenv": set (and delete) environment variables

    ["-f" - force setting even for read-only variables - not
    implemented yet.]

    - end delete [-f] name

    not implemented yet

    ["-f" - force delete even for read-only variables]

    - env save

    same as "saveenv": save environment

    - env export [-t | -b | -c] addr [size]

    export internal representation (hash table) in formats usable for
    persistent storage or processing:

    -t: export as text format; if size is given, data will be
    padded with '\0' bytes; if not, one terminating '\0'
    will be added (which is included in the "filesize"
    setting so you can for exmple copy this to flash and
    keep the termination).
    -b: export as binary format (name=value pairs separated by
    '\0', list end marked by double "\0\0")
    -c: export as checksum protected environment format as
    used for example by "saveenv" command
    addr: memory address where environment gets stored
    size: size of output buffer

    With "-c" and size is NOT given, then the export command will
    format the data as currently used for the persistent storage,
    i. e. it will use CONFIG_ENV_SECT_SIZE as output block size and
    prepend a valid CRC32 checksum and, in case of resundant
    environment, a "current" redundancy flag. If size is given, this
    value will be used instead of CONFIG_ENV_SECT_SIZE; again, CRC32
    checksum and redundancy flag will be inserted.

    With "-b" and "-t", always only the real data (including a
    terminating '\0' byte) will be written; here the optional size
    argument will be used to make sure not to overflow the user
    provided buffer; the command will abort if the size is not
    sufficient. Any remainign space will be '\0' padded.

    On successful return, the variable "filesize" will be set.
    Note that filesize includes the trailing/terminating '\0'
    byte(s).

    Usage szenario: create a text snapshot/backup of the current
    settings:

    => env export -t 100000
    => era ${backup_addr} +${filesize}
    => cp.b 100000 ${backup_addr} ${filesize}

    Re-import this snapshot, deleting all other settings:

    => env import -d -t ${backup_addr}

    - env import [-d] [-t | -b | -c] addr [size]

    import external format (text or binary) into hash table,
    optionally deleting existing values:

    -d: delete existing environment before importing;
    otherwise overwrite / append to existion definitions
    -t: assume text format; either "size" must be given or the
    text data must be '\0' terminated
    -b: assume binary format ('\0' separated, "\0\0" terminated)
    -c: assume checksum protected environment format
    addr: memory address to read from
    size: length of input data; if missing, proper '\0'
    termination is mandatory

    - env default -f

    reset default environment: drop all environment settings and load
    default environment

    - env ask name [message] [size]

    same as "askenv": ask for environment variable

    - env edit name

    same as "editenv": edit environment variable

    - env run

    same as "run": run commands in an environment variable

    ======================================================================

    TODO:

    - drop default env as implemented now; provide a text file based
    initialization instead (eventually using several text files to
    incrementally build it from common blocks) and a tool to convert it
    into a binary blob / object file.

    - It would be nice if we could add wildcard support for environment
    variables; this is needed for variable name auto-completion,
    but it would also be nice to be able to say "printenv ip*" or
    "printenv *addr*"

    - Some boards don't link any more due to the grown code size:
    DU405, canyonlands, sequoia, socrates.

    The AmigaOneG3SE board has been orphaned or a very long time, and
    broken for more than 12 releases resp. more than 3 years. As nobody
    seems to be interested any more in this stuff we may as well ged rid
    of it, especially as it clutters many areas of the code so it is a
    continuous pain for all kinds of ongoing work.

    The only environment type that uses this variable is spi flash, and that is
    only because it is reimplementing the common set_default_env() function.
    So fix the spi flash code and kill off the default_environment_size in the
    process.
