Subject: [PATCH 004/309] Handle the x86/x86_64 split when downloading
 setup.ini

Cygwin recently introduced an x86_64 version and so all the mirrors
now have x86 or x86_64 in their paths, depending on which version
you've installed.

The only change required is when the setup file is fetched.

The setup file itself contains the paths prefixed with either
x86 or x86_64

+Known Problem
+------------
+### Check setup (cygcheck -c) can not detect .tar.xz packages
+At cygwin 1.7.25, cygcheck is hardcoded for .tar.gz and .tar.bz2.
+So check setup (cygcheck -c) can not detect .tar.xz packages.
+This bug was already fixed with [src/winsup/utils/dump_setup.cc#rev1.28](http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/utils/dump_setup.cc?cvsroot=src#rev1.28).
+Please wait a release of cygwin 1.7.26.

Subject: [PATCH 034/309] Change place of GUNPGHOME for apt-cyg.

In previous version, GNUPGHOME for apt-cyg had been set "$cache/apt-cyg/.gnupg".
But there are some inconveniences.
For example, if you downloaded apt-cyg into "$cache/", GNUPGHOME could not be initialized.
So this patch change GNUPGHOME for apt-cyg from "$cache/apt-cyg/.gnupg" to "$cache/.apt-cyg"

In additionally, a error handler for initializing GNUPGHOME is added.

 Quick start
 -----------
 
 apt-cyg is a simple script. Once you have a copy, make it executable:
 
-  # chmod +x /bin/apt-cyg
+    # chmod +x /bin/apt-cyg
 
 Optionally place apt-cyg in a bin/ folder on your path.
 
 Then use apt-cyg, for example:
 
-  # apt-cyg install nano
+    # apt-cyg install nano
 
-True multi-architecture support
+New features
 ------------
 
+### True multi-architecture support
+
 Let think a case that you want to install the x86 package when you are working under the x86_64 environment.
 In this case, You must only append a --charch option to the first parameter of apt-cyg.
 For example:
 
-  # apt-cyg --charch x86 install chere
+    # apt-cyg --charch x86 install chere
 
 As of 2013-10-26, chere package is provided for only the repository for x86.
 
 Remarks:
 Of course, you must install both environments of x86_64 and x86, beforehand.
 
+### Signature check and key management by GnuPG
+
+The default action of apt-cyg has been changed to check signature for 'setup.ini'.
+Of course you can also avoid signature check by using --no-verify or -X options.
+Public keys of cygwin and cygwinports are already registered to trusted keys of embeded.
+If you want to use some other public keys, please use key-* subcommands.

+* Support multi mirrors: Cygwin setup can use multi mirrors. They are recorded at last-mirror section in '/etc/setup/setup.rc'. It's useful for using [Cygwinports](http://cygwinports.org/).

+* Support upgrade: But maybe, busy resources can not be upgraded, and rebase problem will happen. Cygwin setup resolves by replacing them at next reboot.
+* Support dependency check for remove subcommand.
 
 Known Problem
 ------------
-### Check setup (cygcheck -c) can not detect .tar.xz packages
+### FIXED: Check setup (cygcheck -c) can not detect .tar.xz packages
 At cygwin 1.7.25, cygcheck is hardcoded for .tar.gz and .tar.bz2.
 So check setup (cygcheck -c) can not detect .tar.xz packages.
 This bug was already fixed with [src/winsup/utils/dump_setup.cc#rev1.28](http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/utils/dump_setup.cc?cvsroot=src#rev1.28).
 Please wait a release of cygwin 1.7.26.
+
+This Problem was fixed [cygwin 1.7.26](http://cygwin.com/ml/cygwin-announce/2013-11/msg00027.html) which released at 2013-11-29.

 Public keys of cygwin and cygwinports are already registered to trusted keys of embeded.
 If you want to use some other public keys, please use key-* subcommands.
 
+### Proxy support
+
+Use --proxy, -p option.
+This option must take a parameter from one of "auto", "inherit", "none" and URL.
+
+* "auto" will determine a proxy using a part of the [Web Proxy Autodiscovery Protocol](http://en.wikipedia.org/wiki/Web_Proxy_Autodiscovery_Protocol).
+The current implementation will look for a string of "PROXY URL" from "http://wpad/wpad.dat".
+If "wpad.dat" could not be downloaded, the proxy settings are inherited from the parent environment.
+* "inherit" will inherit the proxy settings from the parent environment.
+* "none" will not use the proxy.
+* URL can take a string like "protocol://hostname:port".
+
+For example:
+
+    # apt-cyg --proxy http://proxy.home:8080 update

+It will be automatically updated when apt-cyg is upgraded to newer version.
+If you don't want to update it automatically, execute `completion-install` subcommand in conjunction with `--completion-disable-autoupdate` option.

+Some other forks, [Milly / apt-cyg](https://github.com/Milly/apt-cyg) under the cfg / apt-cyg fork, [ashumkin / apt-cyg](https://github.com/ashumkin/apt-cyg) and etc, are also supported it.

 * Support multi mirrors: Cygwin setup can use multi mirrors. They are recorded at last-mirror section in '/etc/setup/setup.rc'. It's useful for using [Cygwinports](http://cygwinports.org/).
-* Support completion: Some other forks already supported it. For example, [Milly / apt-cyg](https://github.com/Milly/apt-cyg) under the cfg / apt-cyg fork, [ashumkin / apt-cyg](https://github.com/ashumkin/apt-cyg) and etc supported it.
 * Support upgrade: But maybe, busy resources can not be upgraded, and rebase problem will happen. Cygwin setup resolves by replacing them at next reboot.
 * Support dependency check for remove subcommand.

+
+In recent version, the cygwin changed the ACL mechanism .
+So, in the cygwin current version, if it will be installed by setup.exe with -B or --no-admin option,
+the cygwin root (/) does not have correct ACL.
+
+A new subcommand `repair-acl` tries to repair it.

 To solve this problem, the backend of `verify_signatures` function was changed from `gpgv` to `gpg`.

Subject: [PATCH 154/309] Bugfix: The process of `remove` subcommand was not
 precise.

In some packages,
postinstall scripts and preremove scripts were not detected.
Because, these scripts do not always have to be `$pkg.sh`.

Empty directories were not removed.

Subject: [PATCH 163/309] Make apt-cyg update work

Summary:
I get "bad signature" errors when I try to run "apt-cyg updates".

Expected:
apt-cyg update
...skip...
signature verified: setup.bz2.sig
...skip...

Actual:
Cache directory is /setup
Mirror is http://cygwin.mirror.constant.com
Updating setup.ini
setup.bz2      100%[=========================================================>]   3.53M  2.53MB/s    in 1.4s
2018-04-23 16:26:24 URL:http://cygwin.mirror.constant.com/x86/setup.bz2 [3700347/3700347] -> "setup.bz2" [1]
setup.bz2.sig  100%[=========================================================>]      72  --.-KB/s    in 0s
2018-04-23 16:26:24 URL:http://cygwin.mirror.constant.com/x86/setup.bz2.sig [72/72] -> "setup.bz2.sig" [1]
Error: BAD signature: setup.bz2.sig

1. Use --verify to avoid "gpg: WARNING: no command supplied.  Trying to guess what you mean ..."
2. Use --keyring pubring.kbx because pubring.gpg does not exist (at least not for my tests)
3. Use --no-default-keyring (I wish I knew exactly why, I just know that gpg returns 2 not 0 if you don't use that)

Even with all of that you still need to interactively set up gpg:
export GNUPGHOME="$cache/.apt-cyg"
gpg --gen-key
gpg --edit-key Cygwin # (set trust to 4)
gpg --edit-key Yaakov

+### Known Problems
+
+---
+
+### 2016-02-12: Problems about the ACL
+
+In recent version, the cygwin changed the ACL mechanism .
+So, in the cygwin current version, if it will be installed by `setup.exe` with `-B` or `--no-admin` option,
+the cygwin root (/) does not have correct ACL.
+
+A new subcommand `repair-acl` tries to repair it.
+But some package, that are failed to install by the ACL problem, need to be reinstalled.
+
+
+
+### 2015-04-09: gpgv seems not work correctly on 32 bit environment
+
+To solve this problem, the backend of `verify_signatures` function was changed from `gpgv` to `gpg`.
+thienhv reported this problem [#14](https://github.com/kou1okada/apt-cyg/issues/14). Thanks.
+
+### 2014-01-17: ca-certificates package is not setup correct at x86_64 with Windows 8.
+
+After clean installing with `setup-x86_64.exe`, there are something wrong about ca-certificate package as below:
+
+    $ ls -lnG \
+         /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt \
+         /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
+    -r--r--r-- 1 1001 314336 Jan 17 18:17 /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
+    -rw-r--r-- 1 1001      0 Oct 16 12:35 /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
+    $ ls -lnG \
+         /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem \
+         /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
+    -r--r--r-- 1 1001 232342 Jan 17 18:17 /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
+    -rw-r--r-- 1 1001      0 Oct 16 12:35 /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
+
+The x86 environment seems no problem except that need an additional setting for wget and ca-certificate. Hmm,,,    
+
+It seems that `/usr/bin/update-ca-trust` is failed at x86_64.
+
+It's ad hoc, but effective way to fix it, is to copy files from cygwin32 to cygwin64, as below:
+
+    cp -a /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt \
+          /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
+    cp -a /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem \
+          /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
+
+This problem is fixed at 2014-01-24.
+version 0.18.7-1 of p11-kit, p11-kit-trust and libp11-kit0 did not work at the cygwin64 under the Windows 8.
+If you face the above problem, please upgrade these three packages from version 0.18.7-1 to version 0.18.7-2.
+
+For more details, see a thread of below:

+
+### FIXED: Check setup (`cygcheck -c`) can not detect .tar.xz packages
+
+At cygwin 1.7.25, cygcheck is hardcoded for .tar.gz and .tar.bz2.
+So check setup (`cygcheck -c`) can not detect .tar.xz packages.
+This bug was already fixed with [src/winsup/utils/dump_setup.cc#rev1.28](http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/utils/dump_setup.cc?cvsroot=src#rev1.28).
+Please wait a release of cygwin 1.7.26.
+
+This Problem was fixed [cygwin 1.7.26](http://cygwin.com/ml/cygwin-announce/2013-11/msg00027.html) which released at 2013-11-29.

-Known Problem
-------------
-
-### 2016-02-12: Problems about the ACL
-
-In recent version, the cygwin changed the ACL mechanism .
-So, in the cygwin current version, if it will be installed by `setup.exe` with `-B` or `--no-admin` option,
-the cygwin root (/) does not have correct ACL.
-
-A new subcommand `repair-acl` tries to repair it.
-But some package, that are failed to install by the ACL problem, need to be reinstalled.
-
-
-
-### 2015-04-09: gpgv seems not work correctly on 32 bit environment
-
-To solve this problem, the backend of `verify_signatures` function was changed from `gpgv` to `gpg`.
-thienhv reported this problem [#14](https://github.com/kou1okada/apt-cyg/issues/14). Thanks.
-
-### 2014-01-17: ca-certificates package is not setup correct at x86_64 with Windows 8.
-
-After clean installing with `setup-x86_64.exe`, there are something wrong about ca-certificate package as below:

 ------------
 
-### 2016-02-12: Problems about the ACL
-
-In recent version, the cygwin changed the ACL mechanism .
-So, in the cygwin current version, if it will be installed by `setup.exe` with `-B` or `--no-admin` option,
-the cygwin root (/) does not have correct ACL.
-
-A new subcommand `repair-acl` tries to repair it.
-But some package, that are failed to install by the ACL problem, need to be reinstalled.
-
-
-
-### 2015-04-09: gpgv seems not work correctly on 32 bit environment
-
-To solve this problem, the backend of `verify_signatures` function was changed from `gpgv` to `gpg`.
-thienhv reported this problem [#14](https://github.com/kou1okada/apt-cyg/issues/14). Thanks.
-
-### 2014-01-17: ca-certificates package is not setup correct at x86_64 with Windows 8.
-
-After clean installing with `setup-x86_64.exe`, there are something wrong about ca-certificate package as below:
-
-    $ ls -lnG \
-         /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt \
-         /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt

-
-The x86 environment seems no problem except that need an additional setting for wget and ca-certificate. Hmm,,,    
-
-It seems that `/usr/bin/update-ca-trust` is failed at x86_64.
-
-It's ad hoc, but effective way to fix it, is to copy files from cygwin32 to cygwin64, as below:
-
-    cp -a /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt \
-          /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
-    cp -a /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem \
-          /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
-
-This problem is fixed at 2014-01-24.
-version 0.18.7-1 of p11-kit, p11-kit-trust and libp11-kit0 did not work at the cygwin64 under the Windows 8.
-If you face the above problem, please upgrade these three packages from version 0.18.7-1 to version 0.18.7-2.

-### FIXED: Check setup (`cygcheck -c`) can not detect .tar.xz packages
-
-At cygwin 1.7.25, cygcheck is hardcoded for .tar.gz and .tar.bz2.
-So check setup (`cygcheck -c`) can not detect .tar.xz packages.
-This bug was already fixed with [src/winsup/utils/dump_setup.cc#rev1.28](http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/utils/dump_setup.cc?cvsroot=src#rev1.28).
-Please wait a release of cygwin 1.7.26.
-
-This Problem was fixed [cygwin 1.7.26](http://cygwin.com/ml/cygwin-announce/2013-11/msg00027.html) which released at 2013-11-29.

Subject: [PATCH 278/309] Check that iconv command exists

libiconv and thus the iconv command may not be present in a cygwin installation.

This PR adds a check for the availability of iconv on PATH.

Without this check apt-cyg reports very misleading error messages as iconv is called indirectly in a subshell via an eval command. This results in apt-cyg not aborting when the command is not present.

Without this PR:
```
$ apt-cyg find upx

Subject: [PATCH 282/309] Bugfix: The filelist subcommand does not display
 anything in some packages.

For example,
https://cygwin.com/packages/x86_64/gccmakedep/gccmakedep-1.0.3-1
contains the HTML <tt> element around the HTML <pre> element.
That was not matched filter rule of awk.

 But, as of 2015-04-09, the cygwinports project seems still using md5.
 This fork is available for both of cygwin and cygwinports by supporting algorithm of md5, sha1, sha224, sha256 and sha512.
 
-### True multi-architecture support
-
-Let think a case that you want to install the x86 package when you are working under the x86_64 environment.
-For example:
-
-    apt-cyg --charch x86 install chere
-
-As of 2013-10-26, chere package is provided for only the repository for x86.
-
-Remarks:
-Of course, you must install both environments of x86_64 and x86, beforehand.
-
 ### Signature check and key management by GnuPG
 
 The default action of apt-cyg has been changed to check signature for 'setup.ini'.

Subject: [PATCH 308/309] Improve error messages:

* Add a check for iconv to the check for required commands
  at the start of execution.
* Remove the check for iconv before subcommand execution
  as it became unnecessary.

This related to issue #104.
