2020-09-09Silence set-but-unused warning 1.2June McEnroe
getyx is so annoying this way.
2020-09-08Include DEL in characters ncurses will print in ^A formJune McEnroe
2020-09-07Add blank line to unread if there are already unreadJune McEnroe
This fixes the inconsistent M-u behaviour when catgirl is restarting and reconnecting to pounce, for example.
2020-09-07Call uiWrite to insert blank linesJune McEnroe
It only used to use different code to avoid adding the blank line to the soft buffer.
2020-09-07Let wrapped lines use the last columnJune McEnroe
2020-09-06Handle non-alignment tabs in line wrappingJune McEnroe
2020-09-06Add C-r, C-s for basic scrollback searchJune McEnroe
2020-09-03Add M-n, M-p to jump to highlightsJune McEnroe
2020-09-03Fix M-u behaviour difference before and after reflowJune McEnroe
2020-09-02Recalculate unreadHard on reflowJune McEnroe
2020-09-02Give blank lines timestampsJune McEnroe
Otherwise the zero timestamps totally break save data loading! Bad!
2020-09-02Hide ignored messages at the soft -> hard buffer layerJune McEnroe
This restores normal scrolling behaviour.
2020-09-02Don't call completeTouch for ignored messagesJune McEnroe
2020-09-02Preserve style after alignmentJune McEnroe
This makes wrapping text with background colour look much better.
2020-09-02Still add ignored lines to unreadHardJune McEnroe
Scrolling is still affected by hidden lines (which I'm not sure yet is good or not), so for M-u to work it needs to count ignored lines.
2020-09-02Actually insert blank lines in the soft bufferJune McEnroe
So they can be preserved forever!
2020-09-02Reimplement split scrollingJune McEnroe
2020-09-02Fix inserting blank lines BEFORE the new messageJune McEnroe
2020-09-02Only call windowUpdate when the shown window needs updatingJune McEnroe
2020-09-02Don't consider the alignment tab a wrapping pointJune McEnroe
2020-09-02Call wclear on resizeJune McEnroe
Otherwise artefects can appear when resizing to smaller width with wide characters at the right edge of the window.
2020-09-02Fix line wrapping in various waysJune McEnroe
Never split a codepoint, don't set wrapping point unless we're not already wrapping, wrap on any unicode whitespace, only clear rest of line if still on the same line...
2020-09-02Render one main window from buffersJune McEnroe
Still missing: split scrolling and preserving a blank on reflow either from resize or ignore toggling. Anecdata: on one of my instances of catgirl, RAM usage of the previous release was ~30M, RAM usage of this commit was ~12M.
2020-09-01Implement buffer line wrappingJune McEnroe
Not yet rendered in the UI! Just done in parallel.
2020-09-01Invert meaning of unreadHard/unreadSoft to match new buffer codeJune McEnroe
Not sure why I had named them this way. Hard means hard-wrapped.
2020-09-01Factor buffer out of uiJune McEnroe
In preparation for doing line wrapping outside of ncurses.
2020-09-01Move styleParse out of uiJune McEnroe
2020-08-21Use a static buffer for base directory pathsJune McEnroe
2020-08-20Document how cert/priv are searched forJune McEnroe
This has always been how it works, but it was previously undocumented.
2020-08-20Use configPath to load TLS cert/privJune McEnroe
2020-08-20Refactor base dir functions to iterate over pathsJune McEnroe
2020-08-18Match mentions case-sensitivelyJune McEnroe
The mention coloring code already matches case-sensitively, and any proper ping should be using tab-complete anyway so there's no reason for differing case. And the month of June should not ping me.
2020-08-18Preserve colon from previous tab-completeJune McEnroe
This fixes the case when pinging multiple nicks and one of them needs to be cycled through.
2020-08-16Set origin fields to "*" if missingJune McEnroe
Also determine if a message is from the server by if the host field has been copied from the nick field. EFNet sends NOTICEs with no origin during registration. RFC 1459 has this to say: > If the prefix is missing from the message, it is assumed to have > originated from the connection from which it was received. I suppose a more correct implementation would be to set the origin to the hostname of the server, but we don't store that globally, so this is good enough.
2020-08-06Set OPENSSL_BIN to /usr/bin/openssl on FreeBSD 1.1p1June McEnroe
2020-08-05Say for instead of withJune McEnroe
2020-08-04Mention LibreTLS in install instructionsJune McEnroe
2020-08-04Say "OpenSSL" in additional permission noticesJune McEnroe
LibreSSL is "a modified version of that library".
2020-08-03Fix --mandir rendering in READMEJune McEnroe
Fl Fl renders correctly in text but leaves a space between the hyphens in HTML output.
2020-08-02Add \banhammer macroJune McEnroe
From the Textual extras command /banhammer.
2020-08-01Check return value of asprintfJune McEnroe
On the awful operating system GNU, asprintf leaves the destination pointer UNDEFINED on failure.
2020-07-31Use ldd to automatically copy libs into chrootJune McEnroe
2020-07-31Fix path of cert.pem in chrootJune McEnroe
2020-07-31Fix chroot-man pathJune McEnroe
2020-07-30Replace catf with something that tracks lenJune McEnroe
Also the old catf would be broken with -DNDEBUG oops!
2020-07-30Remove dependency on libcrypto for compatJune McEnroe
2020-07-30Define explicit_bzero using memset_s on macOSJune McEnroe
2020-07-30Remove use of strlcatJune McEnroe
catf is not better though and should really be replaced.
2020-07-25Bump .so versions in chrootJune McEnroe
2020-07-23Support --prefix and --mandir in configure script 1.1June McEnroe
a3f531bde50f865cb206a&follow=1'>shell: Add subdir-objects to AM_INIT_AUTOMAKEJason Bowen I've attached a patch which adds the subdir-objects option to AM_INIT_AUTOMAKE. For a while now when I've compiled dash I received a warning from automake that there are source files in a subdirectory but that the subdir-objects automake option was not supplied. I've just been adding it myself, but I finally got around to submitting a patch. The code still compiles for now (i'm using automake 1.15.1), but warning text is rarely nice to see and, if the warning text is to be believed, then the warning will eventually become an error.

This means that if you construct a loop consisting of solely built-in commands and functions, then zombies can hang around indefinitely. This patch fixes this by reaping when necessary after each built-in command and function.

It appears to be working now, however, we have to change our code to detect the no-match case correctly. In particular, we need to test for GLOB_NOMAGIC | GLOB_NOCHECK instead of GLOB_MAGCHAR. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2018-04-02expand: Fix buffer overflow in expandmetaHerbert Xu The native version of expandmeta allocates a buffer that may be overrun for two reasons. First of all the size is 1 byte too small but this is normally hidden because the minimum size is rounded up to 2048 bytes. Secondly, if the directory level is deep enough, any buffer can be overrun. This patch fixes both problems by calling realloc when necessary. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2018-04-02builtin: Move echo space/nl handling into print_escape_strHerbert Xu Currently echocmd uses print_escape_str to do everything apart from printing the spaces/newlines separating its arguments. This patch moves the actual printing into print_escape_str as well using the format parameter. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2018-04-02builtin: Fix echo performance regressionHerbert Xu The commit d6c0e1e2ffbf7913ab69d51cc794d48d41c8fcb1 ("[BUILTIN] Handle embedded NULs correctly in printf") caused a performance regression in the echo built-in because every echo call now goes through the printf %b slow path where the string is always printed twice to ensure the space padding is correct in the presence of NUL characters. In fact this regression applies to printf %b as well. This is easily fixed by making printf %b take the fast path when no precision/field width modifiers are present. This patch also changes the second strchurnul call to strspn which generates slightly better code.

You're right. The proper fix to this is to ensure that nulonly is not set in varvalue for $*. It should only be set for $@ when it's inside double quotes. In fact there is another bug while we're playing with $@/$*. When IFS is set to a non-whitespace character such as :, $* outside quotes won't remove empty fields as it should. This patch fixes both problems.

First of all our tracking of quotemark is wrong so anything after "$@" becomes quoted. Once we fix that then the problem is that the first space character after "$@" is not recognised as an IFS.
