Python 2.7 introduces a backwards incompatible change
|
2010-07-06 13:24:04 +04:00
|
|
|
(Python issue1974, r70772) in email.Generator.Generator code:
|
|
|
|
pre-2.7 code passed "continuation_ws='\t'" to the Header
|
|
|
|
constructor, and 2.7 removed this parameter.
|
|
|
|
|
|
|
|
Default argument is continuation_ws=' ', which means that the
|
2015-08-28 17:53:55 +03:00
|
|
|
behavior is different in <2.7 and 2.7

|
|
|
|
2015-08-28 17:53:55 +03:00
|
|
|
We consider the 2.7 behavior to be preferable, but need
|
|
|
|
to have an unified behavior for versions 2.4 to 2.7

smtp: add the class to verify the certificate of the SMTP server for STARTTLS
Original "smtplib.SMTP" has no route to pass "ca_certs" and
"cert_reqs" arguments to underlying SSL socket creation. This causes
that "getpeercert()" on SSL socket returns empty dict, so the peer
certificate for STARTTLS can't be verified.
This patch introduces the "STARTTLS" class derived from "smtplib.SMTP"
to pass "ca_certs" and "cert_reqs" arguments to underlying SSL socket
creation.
Almost all code of "starttls()" in this class is imported from
"smtplib.SMTP" of Python 2.7.3, but it differs from original code in
points below:
- "self.ehlo_or_helo_if_needed()" invocation is omitted, because:
- "ehlo_or_helo_if_needed()" is available with Python 2.6 or later, and
- "ehlo()" is explicitly invoked in "mercurial.mail._smtp()"
- "if not _have_ssl:" check is omitted, because:
- "_have_ssl" is available with Python 2.6 or later, and
- same checking is done in "mercurial.sslutil.ssl_wrap_socket()"
- "ssl.wrap_socket()" is replaced by "sslutil.ssl_wrap_socket()" for
compatibility between Python versions
- use "sock.recv()" also as "sock.read()", if "sock" doesn't have
"read()" method
with Python 2.5.x or earlier, "sslutil.ssl_wrap_socket()" returns
"httplib.FakeSocket"-ed object, and it doesn't have "read()"
method, which is invoked via "smtplib.SSLFakeFile".

smtp: verify the certificate of the SMTP server for STARTTLS/SMTPS
Before this patch, the certificate of the SMTP server for STARTTLS or
SMTPS isn't verified.
This may cause man-in-the-middle security problem (stealing
authentication information), even though SMTP channel itself is
encrypted by SSL.
When "[smtp] tls" is configured as "smtps" or "starttls", this patch:
- uses classes introduced by preceding patches instead of "SMTP" or
"SMTP_SSL" of smtplib, and
- verifies the certificate of the SMTP server, if "[smtp]
verifycert" is configured as other than False
"[smtp] verifycert" can be configured in 3 levels:
- "strict":
This verifies peer certificate, and aborts if:
- peer certification is not valid, or
- no configuration in "[hostfingerprints]" and "[web] cacerts"
This is default value of "[smtp] verifycert" for security.
- "loose":
This verifies peer certificate, and aborts if peer certification is
not valid.
This just shows warning message ("certificate not verified"), if
there is no configuration in "[hostfingerprints]" and "[web]
cacerts".
This is as same as verification for HTTPS connection.
- False(no verification):
Peer certificate is not verified.
This is as same as the behavior before this patch series.
"hg email --insecure" uses "loose" level, and ignores "[web] cacerts"
as same as push/pull/etc... with --insecure.
Ignoring "[web] cacerts" configuration for "hg email --insecure" is
already done in "dispatch._dispatch()" by looking "insecure" up in the
table of command options.
