Subject: [PATCH 15/96] Extra test - adding date -u -d

match the issuer to the root CA cert subject

* fix format

* fix https://github.com/acmesh-official/acme.sh/issues/3384

* remove the alt files. https://github.com/acmesh-official/acme.sh/issues/3384

* upgrade freebsd and solaris

* duckdns - fix "integer expression expected" errors (#3397)

* fix "integer expression expected" errors

* duckdns fix

* Update dns_duckdns.sh

* Update dns_duckdns.sh

* Implement smtp notify hook

Support notifications via direct SMTP server connection.
Uses Python (2.7.x or 3.4+) to communicate with SMTP server.

* Make shfmt happy

(I'm open to better ways of formatting the heredoc
that embeds the Python script.)

* Only save config if send is successful

* Add instructions for reporting bugs

* Prep for curl or Python; clean up SMTP_* variable usage

* Implement curl version of smtp notify-hook

* More than one blank line is an abomination, apparently

I will not try to use whitespace to group code visually

* Fix: Unifi deploy hook support Unifi Cloud Key (#3327)

* fix: unifi deploy hook also update Cloud Key nginx certs

When running on a Unifi Cloud Key device, also deploy to
/etc/ssl/private/cloudkey.{crt,key} and reload nginx. This
makes the new cert available for the Cloud Key management
app running via nginx on port 443 (as well as the port 8443
Unifi Controller app the deploy hook already supported).

Fixes #3326

* Improve settings documentation comments

* Improve Cloud Key pre-flight error messaging

* Fix typo

* Add support for UnifiOS (Cloud Key Gen2)

Since UnifiOS does not use the Java keystore (like a Unifi
Controller or Cloud Key Gen1 deploy), this also reworks
the settings validation and error messaging somewhat.

* PR review fixes

* Detect unsupported Cloud Key java keystore location

* Don't try to restart inactive services

(and remove extra spaces from reload command)

* Clean up error messages and internal variables

* Change to _getdeployconf/_savedeployconf

* Switch from cp to cat to preserve file permissions

* feat: add huaweicloud error handling

* fix: fix freebsd and solaris

* support openssl 3.0
fix https://github.com/acmesh-official/acme.sh/issues/3399

* make the fix for rsa key only

* Use PROJECT_NAME and VER for X-Mailer header

Also add X-Mailer header to Python version

* Add _clearaccountconf_mutable()

* Rework read/save config to not save default values

Add and use _readaccountconf_mutable_default and
_saveaccountconf_mutable_default helpers to capture
common default value handling.

New approach also eliminates need for separate
underscore-prefixed version of each conf var.

* Implement _rfc2822_date helper

* Clean email headers and warn on unsupported address format

Just in case, make sure CR or NL don't end up in
an email header.

* Clarify _readaccountconf_mutable_default

* Add Date email header in Python implementation

* Use email.policy.default in Python 3 implementation

Improves standards compatibility and utf-8 handling
in Python 3.3-3.8. (email.policy.default becomes the
default in Python 3.9.)

* Prefer Python to curl when both available

* Change default SMTP_SECURE to "tls"

Secure by default. Also try to minimize configuration errors.
(Many ESPs/ISPs require STARTTLS, and most support it.)

* Update dns_dp.sh

没有encode中文字符会导致提交失败

* No need to include EC parameters explicitly with the private key.
(they are embedded)

* Fixes response handling and thereby allow issuing of subdomain certs

* Adds comment

* fix https://github.com/acmesh-official/acme.sh/issues/3402

* dnsapi/ionos: Use POST instead of PATCH for adding TXT record

The API now supports a POST route for adding records. Therefore
checking for already existing records and including them in a PATCH
request is no longer necessary.

* fix https://github.com/acmesh-official/acme.sh/issues/3433

* fix https://github.com/acmesh-official/acme.sh/issues/3019

* fix format

* Update dns_servercow.sh to support wildcard certs

Updated dns_servercow.sh to support txt records with multiple entries. This supports wildcard certificates that require txt records with the same name and different contents.

* Update dns_servercow.sh to support wildcard certs

Updated dns_servercow.sh to support txt records with multiple entries. This supports wildcard certificates that require txt records with the same name and different contents.

* fix https://github.com/acmesh-official/acme.sh/issues/3312

* fix format

* feat: add dns_porkbun

* fix: prevent rate limit

Subject: [PATCH 46/96] Fix: Unifi deploy hook support Unifi Cloud Key (#3327)

* fix: unifi deploy hook also update Cloud Key nginx certs

When running on a Unifi Cloud Key device, also deploy to
/etc/ssl/private/cloudkey.{crt,key} and reload nginx. This
makes the new cert available for the Cloud Key management
app running via nginx on port 443 (as well as the port 8443
Unifi Controller app the deploy hook already supported).

Fixes #3326

* Improve settings documentation comments

* Improve Cloud Key pre-flight error messaging

* Fix typo

* Add support for UnifiOS (Cloud Key Gen2)

Since UnifiOS does not use the Java keystore (like a Unifi
Controller or Cloud Key Gen1 deploy), this also reworks
the settings validation and error messaging somewhat.

* PR review fixes

* Detect unsupported Cloud Key java keystore location

* Don't try to restart inactive services

(and remove extra spaces from reload command)

* Clean up error messages and internal variables

* Change to _getdeployconf/_savedeployconf

* Switch from cp to cat to preserve file permissions

Add and use _readaccountconf_mutable_default and
_saveaccountconf_mutable_default helpers to capture
common default value handling.

New approach also eliminates need for separate
underscore-prefixed version of each conf var.

The API now supports a POST route for adding records. Therefore
checking for already existing records and including them in a PATCH
request is no longer necessary.

Subject: [PATCH 88/96] arguments passed to printf are more generic

On systems that /bin/sh is served by shells other than bash, or
shells that don't implement the same syntax as the bash printf builtin,
printf -- fails to produce the output necessary for standalone operation.

The test case for this was SmartOS, which uses ksh93 as its /bin/sh.

This change uses the more generic method of passing a format parameter
of a single string, and then the argument to replace it with.

Subject: [PATCH 91/96] FIX: Synology sets "default" on wrong certificate

For some DSM installs, it appears that setting the "default" flag to the
string "false" actually sets it to true.  This causes Synology to set
the last updated certificate to be the default certificate.  Using an
empty string appears to still be accepted as a false-y value for DSMs
where this isn't happening and corrects the behavior in the cases that
it was.

Credit to @Run-King for identifying the fix and @buxm for reporting.
