python - "SSLError certificate verify failed" for every domain/url -


i broke ssl setup of machine. every request call ends in certificate verify failed.

i not sure caused this, moved module, had installed va pip install -e . , reinstalled it. after noticed error.

i tried sudo apt-get install libffi-dev , pip install requests[security] --user --upgrade did not help.

here whole output:

import requests; requests.get('https://www.google.com')  --------------------------------------------------------------------------- sslerror                                  traceback (most recent call last) <ipython-input-1-b4a9dae5ffaa> in <module>()       1 import requests ----> 2 requests.get('https://www.google.com')  /home/my_computer/.local/lib/python2.7/site-packages/requests/api.pyc in get(url, params, **kwargs)      65       66     kwargs.setdefault('allow_redirects', true) ---> 67     return request('get', url, params=params, **kwargs)      68       69   /home/my_computer/.local/lib/python2.7/site-packages/requests/api.pyc in request(method, url, **kwargs)      51     # cases, , memory leak in others.      52     sessions.session() session: ---> 53         return session.request(method=method, url=url, **kwargs)      54       55   /home/my_computer/.local/lib/python2.7/site-packages/requests/sessions.pyc in request(self, method, url, params, data, headers, cookies, files, auth, timeout, allow_redirects, proxies, hooks, stream, verify, cert, json)     466         }     467         send_kwargs.update(settings) --> 468         resp = self.send(prep, **send_kwargs)     469      470         return resp  /home/my_computer/.local/lib/python2.7/site-packages/requests/sessions.pyc in send(self, request, **kwargs)     574      575         # send request --> 576         r = adapter.send(request, **kwargs)     577      578         # total elapsed time of request (approximately)  /home/my_computer/.local/lib/python2.7/site-packages/requests/adapters.pyc in send(self, request, stream, timeout, verify, cert, proxies)     445         except (_sslerror, _httperror) e:     446             if isinstance(e, _sslerror): --> 447                 raise sslerror(e, request=request)     448             elif isinstance(e, readtimeouterror):     449                 raise readtimeout(e, request=request)  sslerror: bad handshake: error([('ssl routines', 'ssl3_get_server_certificate', 'certificate verify failed')],)

it same issue here: ssl3_get_server_certificate certificate verify failed on python when requesting (only) *.google.com

to fix 1 needs run:

pip uninstall -y certifi && pip install certifi==2015.04.28

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
