Does not work on Windows + cygwin (php/js)

No php syntax errors detected in 'test.php'

When I run the lint directly:

$ php -l test.php

Parse error: syntax error, unexpected 'adsasdsa' (T_STRING), expecting ',' or ';' in test.php on line 3
Errors parsing test.php

Any hints?

Not sure. I don't have a similar setup at my disposal, but could you try uncommenting the # set -o xtrace fine in the header of the hook? It will show you the full bash trace. Maybe that sheds a light on what happens

(the stdin: lines are red)

[kvz]

Maybe something goes wrong with the stdin redirection. Can you try by adding

tmp="${TMPDIR:-/tmp}/${$}.${ext}"

to the php section, e.g. here? https://github.com/kvz/ochtra/blob/master/pre-commit#L93 (just like for python, yaml, etc)

(let's focus on php, once that works, we can get js to work as well)

[mhujer]

Output is now:

+ tmp=/tmp/7036.php
+ cmd='php -n -l -ddisplay_errors=1 -derror_reporting=E_ALL -dlog_errrors=0 /tmp/7036.php'
+ '[' -n 'php -n -l -ddisplay_errors=1 -derror_reporting=E_ALL -dlog_errrors=0 /tmp/7036.php' ']'
++ echo 'php -n -l -ddisplay_errors=1 -derror_reporting=E_ALL -dlog_errrors=0 /tmp/7036.php'
++ cut '-d ' -f1
+ tool=php
+ paint gray red echo '--> php syntax checking for test.php'

But still No php syntax errors detected in 'test.php'.

I also tried to comment out removing of the tmp file and tried this:

$ php -n -l -ddisplay_errors=1 -derror_reporting=E_ALL -dlog_errrors=0 /tmp/7036.php

Ping @tomasfejfar ? If I can remember, you said it worked for you on Windows, right?

[mhujer]

I just tried yaml file and it works (commit fails for invalid yaml)

[tomasfejfar]

Not sure I use(d) the same version. (I installed by means of http://blog.prskavec.net/2014/01/git-a-pre-commit-hook-pro-kontrolu-syntaxe-v-mnoha-jazycich/) Unfortunatelly (if you remember) I accidentally trashed my .git with FTP sync last week so I can't really tell :(

[kvz]

Maybe pipefail doesn't work. What if you try wihout paint?

e.g. if ! git cat-file -p ${sha} | ${cmd}; then on line 122

Also, what is your bash version? bash --version could tell

[mhujer]

$ bash --version
GNU bash, version 3.1.0(1)-release (i686-pc-msys)
Copyright (C) 2005 Free Software Foundation, Inc.

After changing the line 122, error is reported from php -l (but it is still commited)

But this may be the issue:

$ paint
bash": paint: command not found

But the paint package is not available in cygwin (or is it part of some other package?)

[kvz]

paint is a function declared higher up in the file. It's just cosmetics, giving stdout & stderr a color.

I was thinking that it prevented the php exit code from bubling up because pipefail was ignored. That seems not the case. Even without the paint wrapper, it says "No php syntax errors detected" (and you clearly see the errors).

what if you type

echo "exit code; ${?}" right after the php command? take it outside of the if statement, that should reveil the exist code

[mhujer]

That's probably it:

+ php -n -l -ddisplay_errors=1 -derror_reporting=E_ALL -dlog_errrors=0 /tmp/4960.php

Parse error: syntax error, unexpected 'adsasdsa' (T_STRING), expecting ',' or ';' in C:/Users/Martin/AppData/Local/Temp/4960.php o
n line 4
Errors parsing C:/Users/Martin/AppData/Local/Temp/4960.php
+ echo 'exit code; 0'
exit code; 0

exit code is 0 eventhough there are errors. So I suppose that cygwin does not return proper error codes when it launches Windows apps.

I also tried this:
http://www.cyberciti.biz/faq/shell-how-to-determine-the-exit-status-of-linux-and-unix-command/

$ php -n -l -ddisplay_errors=1 -derror_reporting=E_ALL -dlog_errrors=0 /tmp/4960.php

Parse error: syntax error, unexpected 'adsasdsa' (T_STRING), expecting ',' or ';' in C:/Users/Martin/AppData/Local/Temp/4960.php
n line 4
Errors parsing C:/Users/Martin/AppData/Local/Temp/4960.php

$ echo $?
0


-----------

$ asdasdas
bash": asdasdas: command not found

$ echo $?
127

I will have a look on a cygwin later, to see if I can make the error codes work.
