GENERAL ARGUMENTS (kwargs)
Where possible, the module-level default is indicated, and legal
values are provided.
copy_local = 0 [0|1]
ignored except for file:// urls, in which case it specifies
whether urlgrab should still make a copy of the file, or simply
point to the existing copy. The module level default for this
option is 0.
close_connection = 0 [0|1]
tells URLGrabber to close the connection after a file has been
transferred. This is ignored unless the download happens with the
http keepalive handler (keepalive=1). Otherwise, the connection
is left open for further use. The module level default for this
option is 0 (keepalive connections will not be closed).
keepalive = 1 [0|1]
specifies whether keepalive should be used for HTTP/1.1 servers
that support it. The module level default for this option is 1
(keepalive is enabled).
progress_obj = None
a class instance that supports the following methods:
po.start(filename, url, basename, size, now, text)
# length will be None if unknown
po.update(read) # read == bytes read so far
po.end()
multi_progress_obj = None
a class instance that supports the following methods:
mo.start(total_files, total_size)
mo.newMeter() => meter
mo.removeMeter(meter)
mo.end()
The 'meter' object is similar to progress_obj, but multiple
instances may be created and updated at the same time.
When downloading multiple files in parallel and multi_progress_obj
is None progress_obj is used in compatibility mode: finished files
are shown but there's no in-progress display.
curl_obj = None
a pycurl.Curl instance to be used instead of the default module-level
instance.
Note that you don't have to configure the passed instance in any way;
urlgrabber will do all the necessary work.
This option exists primarily to allow using urlgrabber from multiple
threads in your application, in which case you would want to instantiate a
fresh Curl object for each thread, to avoid race conditions. See the curl
documentation on thread safety for more information:
https://curl.haxx.se/libcurl/c/threadsafe.html
Note that connection reuse (keepalive=1) is limited to the Curl instance it
was enabled on so if you're using multiple instances in your application,
connections won't be shared among them.
text = None
specifies alternative text to be passed to the progress meter
object. If not given, the default progress meter will use the
basename of the file.
throttle = 1.0
a number - if it's an int, it's the bytes/second throttle limit.
If it's a float, it is first multiplied by bandwidth. If throttle
== 0, throttling is disabled. If None, the module-level default
(which can be set on default_grabber.throttle) is used. See
BANDWIDTH THROTTLING for more information.
timeout = 300
a positive integer expressing the number of seconds to wait before
timing out attempts to connect to a server. If the value is None
or 0, connection attempts will not time out. The timeout is passed
to the underlying pycurl object as its CONNECTTIMEOUT option, see
the curl documentation on CURLOPT_CONNECTTIMEOUT for more information.
http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTCONNECTTIMEOUT
minrate = 1000
This sets the low speed threshold in bytes per second. If the server
is sending data slower than this for at least `timeout' seconds, the
library aborts the connection.
bandwidth = 0
the nominal max bandwidth in bytes/second. If throttle is a float
and bandwidth == 0, throttling is disabled. If None, the
module-level default (which can be set on
default_grabber.bandwidth) is used. See BANDWIDTH THROTTLING for
more information.
range = None
a tuple of the form (first_byte, last_byte) describing a byte
range to retrieve. Either or both of the values may set to
None. If first_byte is None, byte offset 0 is assumed. If
last_byte is None, the last byte available is assumed. Note that
the range specification is python-like in that (0,10) will yield
the first 10 bytes of the file.
If set to None, no range will be used.
reget = None [None|'simple'|'check_timestamp']
whether to attempt to reget a partially-downloaded file. Reget
only applies to .urlgrab and (obviously) only if there is a
partially downloaded file. Reget has two modes:
'simple' -- the local file will always be trusted. If there
are 100 bytes in the local file, then the download will always
begin 100 bytes into the requested file.
'check_timestamp' -- the timestamp of the server file will be
compared to the timestamp of the local file. ONLY if the
local file is newer than or the same age as the server file
will reget be used. If the server file is newer, or the
timestamp is not returned, the entire file will be fetched.
NOTE: urlgrabber can do very little to verify that the partial
file on disk is identical to the beginning of the remote file.
You may want to either employ a custom "checkfunc" or simply avoid
using reget in situations where corruption is a concern.
user_agent = 'urlgrabber/VERSION'
a string, usually of the form 'AGENT/VERSION' that is provided to
HTTP servers in the User-agent header. The module level default
for this option is "urlgrabber/VERSION".
http_headers = None
a tuple of 2-tuples, each containing a header and value. These
will be used for http and https requests only. For example, you
can do
http_headers = (('Pragma', 'no-cache'),)
ftp_headers = None
this is just like http_headers, but will be used for ftp requests.
proxies = None
a dictionary that maps protocol schemes to proxy hosts. For
example, to use a proxy server on host "foo" port 3128 for http
and https URLs:
proxies={ 'http' : 'http://foo:3128', 'https' : 'http://foo:3128' }
note that proxy authentication information may be provided using
normal URL constructs:
proxies={ 'http' : 'http://user:host@foo:3128' }
libproxy = False
Use the libproxy module (if installed) to find proxies.
The libproxy code is only used if the proxies dictionary
does not provide any proxies.
no_cache = False
When True, server-side cache will be disabled for http and https
requests. This is equivalent to setting
http_headers = (('Pragma', 'no-cache'),)
prefix = None
a url prefix that will be prepended to all requested urls. For
example:
g = URLGrabber(prefix='http://foo.com/mirror/')
g.urlgrab('some/file.txt')
## this will fetch 'http://foo.com/mirror/some/file.txt'
This option exists primarily to allow identical behavior to
MirrorGroup (and derived) instances. Note: a '/' will be inserted
if necessary, so you cannot specify a prefix that ends with a
partial file or directory name.
opener = None
No-op when using the curl backend (default)
cache_openers = True
No-op when using the curl backend (default)
data = None
Only relevant for the HTTP family (and ignored for other
protocols), this allows HTTP POSTs. When the data kwarg is
present (and not None), an HTTP request will automatically become
a POST rather than GET. This is done by direct passthrough to
urllib2. If you use this, you may also want to set the
'Content-length' and 'Content-type' headers with the http_headers
option. Note that python 2.2 handles the case of these
badly and if you do not use the proper case (shown here), your
values will be overridden with the defaults.
urlparser = URLParser()
The URLParser class handles pre-processing of URLs, including
auth-handling for user/pass encoded in http urls, file handing
(that is, filenames not sent as a URL), and URL quoting. If you
want to override any of this behavior, you can pass in a
replacement instance. See also the 'quote' option.
quote = None
Whether or not to quote the path portion of a url.
quote = 1 -> quote the URLs (they're not quoted yet)
quote = 0 -> do not quote them (they're already quoted)
quote = None -> guess what to do
This option only affects proper urls like 'file:///etc/passwd'; it
does not affect 'raw' filenames like '/etc/passwd'. The latter
will always be quoted as they are converted to URLs. Also, only
the path part of a url is quoted. If you need more fine-grained
control, you should probably subclass URLParser and pass it in via
the 'urlparser' option.
username = None
username to use for simple http auth - is automatically quoted for special characters
password = None
password to use for simple http auth - is automatically quoted for special characters
ssl_ca_cert = None
this option can be used if M2Crypto is available and will be
ignored otherwise. If provided, it will be used to create an SSL
context. If both ssl_ca_cert and ssl_context are provided, then
ssl_context will be ignored and a new context will be created from
ssl_ca_cert.
ssl_context = None
No-op when using the curl backend (default)
ssl_verify_peer = True
Check the server's certificate to make sure it is valid with what our CA validates
ssl_verify_host = True
Check the server's hostname to make sure it matches the certificate DN
ssl_key = None
Path to the key the client should use to connect/authenticate with
ssl_key_type = 'PEM'
PEM or DER - format of key
ssl_cert = None
Path to the ssl certificate the client should use to to authenticate with
ssl_cert_type = 'PEM'
PEM or DER - format of certificate
ssl_key_pass = None
password to access the ssl_key
size = None
size (in bytes) or Maximum size of the thing being downloaded.
This is mostly to keep us from exploding with an endless datastream
max_header_size = 2097152
Maximum size (in bytes) of the headers.
ip_resolve = 'whatever'
What type of name to IP resolving to use, default is to do both IPV4 and
IPV6.
async = (key, limit)
When this option is set, the urlgrab() is not processed immediately
but queued. parallel_wait() then processes grabs in parallel, limiting
the numer of connections in each 'key' group to at most 'limit'.
max_connections
The global connection limit.
timedhosts
The filename of the host download statistics. If defined, urlgrabber
will update the stats at the end of every download. At the end of
parallel_wait(), the updated stats are saved. If synchronous grabs
are used, you should call th_save().
default_speed, half_life
These options only affect the async mirror selection code.
The default_speed option sets the speed estimate for mirrors
we have never downloaded from, and defaults to 1 MBps.
The speed estimate also drifts exponentially from the speed
actually measured to the default speed, with default
period of 30 days.
ftp_disable_epsv = False
False, True
This options disables Extended Passive Mode (the EPSV command)
which does not work correctly on some buggy ftp servers.
RETRY RELATED ARGUMENTS
retry = None
the number of times to retry the grab before bailing. If this is
zero, it will retry forever. This was intentional... really, it
was :). If this value is not supplied or is supplied but is None
retrying does not occur.
retrycodes = [-1,2,4,5,6,7]
a sequence of errorcodes (values of e.errno) for which it should
retry. See the doc on URLGrabError for more details on this. You
might consider modifying a copy of the default codes rather than
building yours from scratch so that if the list is extended in the
future (or one code is split into two) you can still enjoy the
benefits of the default list. You can do that with something like
this:
retrycodes = urlgrabber.grabber.URLGrabberOptions().retrycodes
if 12 not in retrycodes:
retrycodes.append(12)
checkfunc = None
a function to do additional checks. This defaults to None, which
means no additional checking. The function should simply return
on a successful check. It should raise URLGrabError on an
unsuccessful check. Raising of any other exception will be
considered immediate failure and no retries will occur.
If it raises URLGrabError, the error code will determine the retry
behavior. Negative error numbers are reserved for use by these
passed in functions, so you can use many negative numbers for
different types of failure. By default, -1 results in a retry,
but this can be customized with retrycodes.
If you simply pass in a function, it will be given exactly one
argument: a CallbackObject instance with the .url attribute
defined and either .filename (for urlgrab) or .data (for urlread).
For urlgrab, .filename is the name of the local file. For
urlread, .data is the actual string data. If you need other
arguments passed to the callback (program state of some sort), you
can do so like this:
checkfunc=(function, ('arg1', 2), {'kwarg': 3})
if the downloaded file has filename /tmp/stuff, then this will
result in this call (for urlgrab):
function(obj, 'arg1', 2, kwarg=3)
# obj.filename = '/tmp/stuff'
# obj.url = 'http://foo.com/stuff'
NOTE: both the "args" tuple and "kwargs" dict must be present if
you use this syntax, but either (or both) can be empty.
failure_callback = None
The callback that gets called during retries when an attempt to
fetch a file fails. The syntax for specifying the callback is
identical to checkfunc, except for the attributes defined in the
CallbackObject instance. The attributes for failure_callback are:
exception = the raised exception
url = the url we're trying to fetch
tries = the number of tries so far (including this one)
retry = the value of the retry option
retry_no_cache = the value of the retry_no_cache option
The callback is present primarily to inform the calling program of
the failure, but if it raises an exception (including the one it's
passed) that exception will NOT be caught and will therefore cause
future retries to be aborted.
The callback is called for EVERY failure, including the last one.
On the last try, the callback can raise an alternate exception,
but it cannot (without severe trickiness) prevent the exception
from being raised.
failfunc = None
The callback that gets called when urlgrab request fails.
If defined, urlgrab() calls it instead of raising URLGrabError.
Callback syntax is identical to failure_callback.
Contrary to failure_callback, it's called only once. It's primary
purpose is to use urlgrab() without a try/except block.
interrupt_callback = None
This callback is called if KeyboardInterrupt is received at any
point in the transfer. Basically, this callback can have three
impacts on the fetch process based on the way it exits:
1) raise no exception: the current fetch will be aborted, but
any further retries will still take place
2) raise a URLGrabError: if you're using a MirrorGroup, then
this will prompt a failover to the next mirror according to
the behavior of the MirrorGroup subclass. It is recommended
that you raise URLGrabError with code 15, 'user abort'. If
you are NOT using a MirrorGroup subclass, then this is the
same as (3).
3) raise some other exception (such as KeyboardInterrupt), which
will not be caught at either the grabber or mirror levels.
That is, it will be raised up all the way to the caller.
This callback is very similar to failure_callback. They are
passed the same arguments, so you could use the same function for
both.
retry_no_cache = False
When True, automatically enable no_cache for future retries if
checkfunc performs an unsuccessful check.
This option is useful if your application expects a set of files
from the same server to form an atomic unit and you write your
checkfunc to ensure each file being downloaded belongs to such a
unit. If transparent proxy caching is in effect, the files can
become out-of-sync, disrupting the atomicity. Enabling this option
will prevent that, while ensuring that you still enjoy the benefits
of caching when possible.
BANDWIDTH THROTTLING
urlgrabber supports throttling via two values: throttle and
bandwidth Between the two, you can either specify and absolute
throttle threshold or specify a theshold as a fraction of maximum
available bandwidth.
throttle is a number - if it's an int, it's the bytes/second
throttle limit. If it's a float, it is first multiplied by
bandwidth. If throttle == 0, throttling is disabled. If None, the
module-level default (which can be set with set_throttle) is used.
bandwidth is the nominal max bandwidth in bytes/second. If throttle
is a float and bandwidth == 0, throttling is disabled. If None, the
module-level default (which can be set with set_bandwidth) is used.
Note that when multiple downloads run simultaneously (multiprocessing
or the parallel urlgrab() feature is used) the total bandwidth might
exceed the throttle limit. You may want to also set max_connections=1
or scale your throttle option down accordingly.
THROTTLING EXAMPLES:
Lets say you have a 100 Mbps connection. This is (about) 10^8 bits
per second, or 12,500,000 Bytes per second. You have a number of
throttling options:
*) set_bandwidth(12500000); set_throttle(0.5) # throttle is a float
This will limit urlgrab to use half of your available bandwidth.
*) set_throttle(6250000) # throttle is an int
This will also limit urlgrab to use half of your available
bandwidth, regardless of what bandwidth is set to.
*) set_throttle(6250000); set_throttle(1.0) # float
Use half your bandwidth
*) set_throttle(6250000); set_throttle(2.0) # float
Use up to 12,500,000 Bytes per second (your nominal max bandwidth)
*) set_throttle(6250000); set_throttle(0) # throttle = 0
Disable throttling - this is more efficient than a very large
throttle setting.
*) set_throttle(0); set_throttle(1.0) # throttle is float, bandwidth = 0
Disable throttling - this is the default when the module is loaded.
SUGGESTED AUTHOR IMPLEMENTATION (THROTTLING)
While this is flexible, it's not extremely obvious to the user. I
suggest you implement a float throttle as a percent to make the
distinction between absolute and relative throttling very explicit.
Also, you may want to convert the units to something more convenient
than bytes/second, such as kbps or kB/s, etc.

the environment variable URLGRABBER_DEBUG is set, but can also be

the logging module and would like to incorporate urlgrabber logging,
then it can do so this way. It's probably not necessary as most
internal logging is only for debugging purposes.
The passed-in object should be a logging.Logger instance. It will
be pushed into the keepalive and byterange modules if they're
being used. The mirror module pulls this object in on import, so
you will need to manually push into it. In fact, you may find it
tidier to simply push your logging object (or objects) into each
of these modules independently.

[ this range reserved for application-specific error codes ]
Retry codes (< 0)
-1 - retry the download, unknown reason
Note: to test which group a code is in, you can simply do integer
division by 256: e.errno / 256
Negative codes are reserved for use by functions passed in to
retrygrab with checkfunc. The value -1 is built in as a generic
retry code and is already included in the retrycodes list.
Therefore, you can create a custom check function that simply
returns -1 and the fetch will be re-tried. For more customized
retries, you can use other negative number and include them in
retry-codes. This is nice for outputting useful messages about
what failed.
You can use these error codes like so:
try: urlgrab(url)
except URLGrabError, e:
if e.errno == 3: ...
# or
print e.strerror
# or simply
print e #### print '[Errno %i] %s' % (e.errno, e.strerror)

This is currently a dummy class into which urlgrabber can stuff
information for passing to callbacks. This way, the prototype for
all callbacks is the same, regardless of the data that will be
passed back. Any function that accepts a callback function as an
argument SHOULD document what it will define in this object.
It is possible that this class will have some greater
functionality in the future.

This class does several things:
* add any prefix
* translate a "raw" file to a proper file: url
* handle any http or https auth that's encoded within the url
* quote the url
Only the "parse" method is called directly, and it calls sub-methods.
An instance of this class is held in the options object, which
means that it's easy to change the behavior by sub-classing and
passing the replacement in. It need only have a method like:
url, parts = urlparser.parse(url, opts)
c C sE t | } | j } | j r6 | j | | j } n t j | } | \ } } } } } }

Note: a raw file WILL be quoted when it's converted to a URL.
However, other urls (ones which come with a proper scheme) may
or may not be quoted according to opts.quote
opts.quote = 1 --> quote it
opts.quote = 0 --> do not quote it
opts.quote = None --> guess

This method quotes ONLY the path part. If you need to quote
other parts, you should override this and pass in your derived
class. The other alternative is to quote other parts before
passing into urlgrabber.
